1.1.1.3 ! misho       1: NEWS for rsync 3.1.1 (22 Jun 2014)
        !             2: Protocol: 31 (unchanged)
        !             3: Changes since 3.1.0:
        !             4: 
        !             5:   BUG FIXES:
        !             6: 
        !             7:     - If the receiver gets bogus filenames from the sender (an unexpected
        !             8:       leading slash or a ".." infix dir), exit with an error.  This prevents a
        !             9:       malicious sender from trying to inject filenames that would affect an
        !            10:       area outside the destination directories.
        !            11: 
        !            12:     - Fixed a failure to remove the partial-transfer temp file when interrupted
        !            13:       (and rsync is not saving the partial files).
        !            14: 
        !            15:     - Changed the chown/group/xattr-set order to avoid losing some security-
        !            16:       related xattr info (that would get cleared by a chown).
        !            17: 
        !            18:     - Fixed a bug in the xattr-finding code that could make a non-root-run
        !            19:       receiver not able to find some xattr numbers.
        !            20: 
        !            21:     - Fixed a bug in the early daemon protocol where a timeout failed to be
        !            22:       honored (e.g. if the remote side fails to send us the initial protocol
        !            23:       greeting).
        !            24: 
        !            25:     - Fixed unintended inclusion of commas in file numbers in the daemon log.
        !            26: 
        !            27:     - We once again send the 'f' sub-flag (of -e) to the server side so it
        !            28:       knows that we can handle incremental-recursion directory errors properly
        !            29:       in older protocols.
        !            30: 
        !            31:     - Fixed an issue with too-aggressive keep-alive messages causing a problem
        !            32:       for older rsync versions early in the transfer.
        !            33: 
        !            34:     - Fixed an incorrect message about backup-directory-creation when using
        !            35:       --dry-run and the backup dir is not an absolute path.
        !            36: 
        !            37:     - Fixed a bug where a failed deletion and/or a failed sender-side removal
        !            38:       would not affect the exit code.
        !            39: 
        !            40:     - Fixed a bug that caused a failure when combining --delete-missing-args
        !            41:       with --xattrs and/or --acls.
        !            42: 
        !            43:     - Fixed a strange dir_depth assertion error that was caused by empty-dir
        !            44:       removals and/or duplicate files in the transfer.
        !            45: 
        !            46:     - Fixed a problem with --info=progress2's output stats where rsync would
        !            47:       only update the stats at the end of each file's transfer.  It now uses
        !            48:       the data that is flowing for the current file, making the stats more
        !            49:       accurate and less jumpy.
        !            50: 
        !            51:     - Fixed an itemize bug that affected the combo of --link-dest, -X, and -n.
        !            52: 
        !            53:     - Fixed a problem with delete messages not appearing in the log file when
        !            54:       the user didn't use --verbose.
        !            55: 
        !            56:     - Improve chunked xattr reading for OS X.
        !            57: 
        !            58:     - Removed an attempted hard-link xattr optimization that was causing a
        !            59:       transfer failure.  This removal is flagged in the compatibility code, so
        !            60:       if a better fix can be discovered, we have a way to flip it on again.
        !            61: 
        !            62:     - Fixed a bug when the receiver is not configured to be able to hard link
        !            63:       symlimks/devices/special-file items but the sender sent some of these
        !            64:       items flagged as hard-linked.
        !            65: 
        !            66:     - We now generate a better error if the buffer overflows in do_mknod().
        !            67: 
        !            68:     - Fixed a problem reading more than 16 ACLs on some OSes.
        !            69: 
        !            70:     - Fixed the reading of the secrets file to avoid an infinite wait when
        !            71:       the username is missing.
        !            72: 
        !            73:     - Fixed a parsing problem in the --usermap/--groupmap options when using
        !            74:       MIN-MAX numbers.
        !            75: 
        !            76:     - Switched Cygwin back to using socketpair "pipes" to try to speed it up.
        !            77: 
        !            78:     - Added knowledge of a few new options to rrsync.
        !            79: 
        !            80:   ENHANCEMENTS:
        !            81: 
        !            82:     - Tweaked the temp-file naming when --temp-dir=DIR is used: the temp-file
        !            83:       names will not get a '.' prepended.
        !            84: 
        !            85:     - Added support for a new-compression idiom that does not compress all the
        !            86:       matching data in a transfer.  This can help rsync to use less cpu when a
        !            87:       transfer has a lot of matching data, and also makes rsync compatible with
        !            88:       a non-bundled zlib.  See the --new-compress and --old-compress options in
        !            89:       the manpage.
        !            90: 
        !            91:     - Added the support/rsync-no-vanished wrapper script.
        !            92: 
        !            93:     - Made configure more prominently mention when we failed to find yodl (in
        !            94:       case the user wants to be able to generate manpages from *.yo files).
        !            95: 
        !            96:     - Have manpage mention how a daemon's max-verbosity setting affects info
        !            97:       and debug options.  Also added more clarification on backslash removals
        !            98:       for excludes that contain wildcards.
        !            99: 
        !           100:     - Have configure check if for the attr lib (for getxattr) for those systems
        !           101:       that need to link against it explicitly.
        !           102: 
        !           103:     - Change the early dir-creation logic to only use that idiom in an
        !           104:       inc-recursive copy that is preserving directory times. e.g. using
        !           105:       --omit-dir-times will avoid these early directories being created.
        !           106: 
        !           107:     - Fix a bug in cmp_time() that would return a wrong result if the 2 times
        !           108:       differed by an amount greater than what a time_t can hold.
        !           109: 
        !           110:   DEVELOPER RELATED:
        !           111: 
        !           112:     - We now include an example systemd file (in packaging/systemd).
        !           113: 
        !           114:     - Tweaked configure to make sure that any intended use of the included popt
        !           115:       and/or zlib code is put early in the CFLAGS.
        !           116: 
        !           117: NEWS for rsync 3.1.0 (28 Sep 2013)
        !           118: Protocol: 31 (changed)
        !           119: Changes since 3.0.9:
        !           120: 
        !           121:   OUTPUT CHANGES:
        !           122: 
        !           123:     - Output numbers in 3-digit groups by default (e.g. 1,234,567).  See the
        !           124:       --human-readable option for a way to turn it off.  See also the daemon's
        !           125:       "log format" parameter and related command-line options (including
        !           126:       --out-format) for a modifier that can be used to request digit-grouping
        !           127:       or human-readable output in log escapes. (Note that log output is
        !           128:       unchanged by default.)
        !           129: 
        !           130:     - The --list-only option is now affected by the --human-readable setting.
        !           131:       It will display digit groupings by default, and unit suffixes if higher
        !           132:       levels of readability are requested.  Also, the column width for the size
        !           133:       output has increased from 11 to 14 characters when human readability is
        !           134:       enabled.  Use --no-h to get the old-style output and column size.
        !           135: 
        !           136:     - The output of the --progress option has changed:  the string "xfer" was
        !           137:       shortened to "xfr", and the string "to-check" was shortened to "to-chk",
        !           138:       both designed to make room for the (by default) wider display of file
        !           139:       size numbers without making the total line-length longer.  Also, when
        !           140:       incremental recursion is enabled, the string "ir-chk" will be used
        !           141:       instead of "to-chk" up until the incremental-recursion scan is done,
        !           142:       letting you know that the value to check and the total value will still
        !           143:       be increasing as new files are found.
        !           144: 
        !           145:     - Enhanced the --stats output: 1) to mention how many files were created
        !           146:       (protocol >= 28), 2) to mention how many files were deleted (a new line
        !           147:       for protocol 31, but only output when --delete is in effect), and 3) to
        !           148:       follow the file-count, created-count, and deleted-count with a subcount
        !           149:       list that shows the counts by type.  The wording of the transferred count
        !           150:       has also changed so that it is clearer that it is only a count of regular
        !           151:       files.
        !           152: 
        !           153:   BUG FIXES:
        !           154: 
        !           155:     - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a
        !           156:       full output buffer.
        !           157: 
        !           158:     - Fixed some rare bugs in --iconv processing that might cause a multibyte
        !           159:       character to get translated incorrectly.
        !           160: 
        !           161:     - Fixed a bogus "vanished file" error if some files were specified with
        !           162:       "./" prefixes and others were not.
        !           163: 
        !           164:     - Fixed a bug in --sparse where an extra gap could get inserted after a
        !           165:       partial write.
        !           166: 
        !           167:     - Changed the way --progress overwrites its prior output in order to make
        !           168:       it nearly impossible for the progress to get overwritten by an error.
        !           169: 
        !           170:     - Improved the propagation of abnormal-exit error messages.  This should
        !           171:       help the client side to receive errors from the server when it is exiting
        !           172:       abnormally, and should also avoid dying with an "connection unexpectedly
        !           173:       closed" exit when the closed connection is really expected.
        !           174: 
        !           175:     - The sender now checks each file it plans to remove to ensure that it
        !           176:       hasn't changed from the first stat's info.  This helps to avoid losing
        !           177:       file data when the user is not using the option in a safe manner.
        !           178: 
        !           179:     - Fixed a data-duplication bug in the compress option that made compression
        !           180:       less efficient.  This improves protocol 31 onward, while behaving in a
        !           181:       compatible (buggy) manner with older rsync protocols.
        !           182: 
        !           183:     - When creating a temp-file, rsync is now a bit smarter about it dot-char
        !           184:       choices, which can fix a problem on OS X with names that start with "..".
        !           185: 
        !           186:     - Rsync now sets a cleanup flag for --inplace and --append transfers that
        !           187:       will flush the write buffer if the transfer aborts.  This ensures that
        !           188:       more received data gets written out to the disk on an aborted transfer
        !           189:       (which is quite helpful on a slow, flaky connection).
        !           190: 
        !           191:     - The reads that map_ptr() now does are aligned on 1K boundaries.  This
        !           192:       helps some filesystems and/or files that don't like unaligned reads.
        !           193: 
        !           194:     - Fix an issue in the msleep() function if time jumps backwards.
        !           195: 
        !           196:     - Fix daemon-server module-name splitting bug where an arg would get split
        !           197:       even if --protect-args was used.
        !           198: 
        !           199:   ENHANCEMENTS:
        !           200: 
        !           201:     - Added the --remote-option=OPT (-M OPT) command-line option that is useful
        !           202:       for things like sending a remote --log-file=FILE or --fake-super option.
        !           203: 
        !           204:     - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained
        !           205:       control over what is output.  Added an extra type of --progress output
        !           206:       using --info=progress2.
        !           207: 
        !           208:     - The --msgs2stderr option can help with debugging rsync by allowing the
        !           209:       debug messages to get output to stderr rather than travel via the socket
        !           210:       protocol.
        !           211: 
        !           212:     - Added the --delete-missing-args and --ignore-missing-args options to
        !           213:       either delete or ignore user-specified files on the receiver that are
        !           214:       missing on the sender (normally the absence of user-specified files
        !           215:       generates an error).
        !           216: 
        !           217:     - Added a "T" (terabyte) category to the --human-readable size suffixes.
        !           218: 
        !           219:     - Added the --usermap/--groupmap/--chown options for manipulating file
        !           220:       ownership during the copy.
        !           221: 
        !           222:     - Added the "%C" escape to the log-output handling, which will output the
        !           223:       MD5 checksum of any transferred file, or all files if --checksum was
        !           224:       specified (when protocol 30 or above is in effect).
        !           225: 
        !           226:     - Added the "reverse lookup" parameter to the rsync daemon config file to
        !           227:       allow reverse-DNS lookups to be disabled.
        !           228: 
        !           229:     - Added a forward-DNS lookup for the daemon's hosts allow/deny config.  Can
        !           230:       be disabled via "forward lookup" parameter (defaults to enabled).
        !           231: 
        !           232:     - Added a way for more than one group to be specified in the daemon's
        !           233:       config file, including a way to specify that you want all of the
        !           234:       specified user's groups without having to name them.  Also changed the
        !           235:       daemon to complain about an inability to set explicitly-specified uid/gid
        !           236:       values, even when not run by a super-user.
        !           237: 
        !           238:     - The daemon now tries to send the user the error messages from the
        !           239:       pre-xfer exec script when it fails.
        !           240: 
        !           241:     - Improved the use of alt-dest options into an existing hierarchy of files:
        !           242:       If a match is found in an alt-dir, it takes precedence over an existing
        !           243:       file.  (We'll need to wait for a future version before attribute-changes
        !           244:       on otherwise unchanged files are safe when using an existing hierarchy.)
        !           245: 
        !           246:     - Added per-user authorization options and group-authorization support to
        !           247:       the daemon's "auth users" parameter.
        !           248: 
        !           249:     - Added a way to reference environment variables in a daemon's config file
        !           250:       (using %VAR% references).
        !           251: 
        !           252:     - When replacing a non-dir with a symlink/hard-link/device/special-file,
        !           253:       the update should now be done in an atomic manner.
        !           254: 
        !           255:     - Avoid re-sending xattr info for hard-linked files w/the same xattrs
        !           256:       (protocol 31).
        !           257: 
        !           258:     - The backup code was improved to use better logic maintaining the backup
        !           259:       directory hierarchy.  Also, when a file is being backed up, rsync tries
        !           260:       to hard-link it into place so that the upcoming replacement of the
        !           261:       destination file will be atomic (for the normal, non-inplace logic).
        !           262: 
        !           263:     - Added the ability to synchronize nano-second modified times.
        !           264: 
        !           265:     - Added a few more default suffixes for the "dont compress" settings.
        !           266: 
        !           267:     - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
        !           268:       the default for the --protect-args command-line option to be overridden.
        !           269: 
        !           270:     - Added the --preallocate command-line option.
        !           271: 
        !           272:     - Allow --password-file=- to read the password from stdin (filename "-").
        !           273: 
        !           274:     - Rsync now comes packaged with an rsync-ssl helper script that can be
        !           275:       used to contact a remote rsync daemon using a piped-stunnel command.
        !           276:       It also includes an stunnel config file to run the server side to
        !           277:       support ssl daemon connections.  See the packaging/lsb/rsync.spec
        !           278:       file for one way to package the resulting files.  (Suggestions for
        !           279:       how to make this even easier to install & use are welcomed.)
        !           280: 
        !           281:     - Improved the speed of some --inplace updates when there are lots of
        !           282:       identical checksum blocks that end up being unusable.
        !           283: 
        !           284:     - Added the --outbuf=N|L|B option for choosing the output buffering.
        !           285: 
        !           286:     - Repeating the --fuzzy option now causes the code to look for fuzzy
        !           287:       matches inside alt-dest directories too.
        !           288: 
        !           289:     - The --chmod option now supports numeric modes, e.g. --chmod=644,D755
        !           290: 
        !           291:     - Added some Solaris xattr code.
        !           292: 
        !           293:     - Made an rsync daemon (the listening process) exit with a 0 status when
        !           294:       it was signaled to die.  This helps launchd.
        !           295: 
        !           296:     - Improved the RSYNC_* environment variables for the pre-xfer exec script:
        !           297:       when a daemon is sent multiple request args, they are now joined into a
        !           298:       single return value (separated by spaces) so that the RSYNC_REQUEST
        !           299:       environment variable is accurate for any "pre-xfer exec".  The values in
        !           300:       RSYNC_ARG# vars are no longer truncated at the "." arg (prior to the
        !           301:       request dirs/files), so that all the requested values are also listed
        !           302:       (separately) in RSYNC_ARG# variables.
        !           303: 
        !           304:   EXTRAS:
        !           305: 
        !           306:     - Added an "instant-rsyncd" script to the support directory, which makes
        !           307:       it easy to configure a simple rsync daemon in the current directory.
        !           308: 
        !           309:     - Added the "mapfrom" and "mapto" scripts to the support directory, which
        !           310:       makes it easier to do user/group mapping in a local transfer based on
        !           311:       passwd/group files from another machine.
        !           312: 
        !           313:     - There's a new, improved version of the lsh script in the support dir:
        !           314:       it's written in perl and supports -u without resorting to using sudo
        !           315:       (when run as root).  The old shell version is now named lsh.sh.
        !           316: 
        !           317:     - There is a helper script named rsync-slash-strip in the support directory
        !           318:       for anyone that wants to change the way rsync handles args with trailing
        !           319:       slashes.  (e.g. arg/ would get stripped to arg while arg/. would turn into
        !           320:       arg/).
        !           321: 
        !           322:   INTERNAL:
        !           323: 
        !           324:     - The I/O code was rewritten to be simpler and do bigger buffered reads
        !           325:       over the socket.  The I/O between the receiver and the generator was
        !           326:       changed to be standard multiplexed-I/O (like that over the socket).
        !           327: 
        !           328:     - The sender tries to use any dead time while the generator is looking for
        !           329:       files to transfer in order to do sender-side directory scanning in a more
        !           330:       parallel manner.
        !           331: 
        !           332:     - A daemon can now inform a client about a daemon-configured timeout value
        !           333:       so that the client can assist in the keep-alive activity (protocol 31).
        !           334: 
        !           335:     - The filter code received some refactoring to make it more extendible, to
        !           336:       read better, and do better sanity checking.
        !           337: 
        !           338:     - Really big numbers are now output using our own big-num routine rather
        !           339:       than casting them to a double and using a %.0f conversion.
        !           340: 
        !           341:     - The pool_alloc library has received some minor improvements in alignment
        !           342:       handling.
        !           343: 
        !           344:     - Added init_stat_x() function to avoid duplication of acl/xattr init code.
        !           345: 
        !           346:     - The included zlib was upgraded from 1.2.3 to 1.2.8.
        !           347: 
        !           348:     - Rsync can now be compiled to use an unmodified zlib library instead of
        !           349:       the tweaked one that is included with rsync.  This will eventually
        !           350:       become the default, at which point we'll start the countdown to removing
        !           351:       the included zlib.  Until then, feel free to configure using:
        !           352: 
        !           353:        ./configure --with-included-zlib=no

        !           355:   DEVELOPER RELATED:
        !           356: 
        !           357:     - Added more conditional debug output.
        !           358: 
        !           359:     - Fixed some build issues for android and minix.

                    368: 
                    369:     - Fix a hang if a hard-linked file cannot be opened by the sender (e.g.
                    370:       if it has no read permission).
                    371: 
                    372:     - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
                    373: 
                    374:     - Fix a memory leak in the xattr code.
                    375: 
                    376:     - Fixed a bug with --delete-excluded when a filter merge file has a rule
                    377:       that specifies a receiver-only side restriction.
                    378: 
                    379:     - Fix a bug with the modifying of unwritable directories.

                    385:     - Fix the directory permissions on an implied dot-dir when using --relative
                    386:       (e.g. /outside/path/././send/path).

                    388:     - Fixed some too-long sleeping instances when using --bwlimit.
                    389: 
                    390:     - Fixed when symlink ownership difference-checking gets compiled into
                    391:       unchanged_attrs().
                    392: 
                    393:     - Improved the socket-error reporting when multiple protocols fail.
                    394: 
                    395:     - Fixed a case where a socket error could reference just-freed memory.
                    396:

                    406:       declaration).
                    407:

1.1       misho     418: NEWS for rsync 3.0.8 (26 Mar 2011)
                    419: Protocol: 30 (unchanged)
                    420: Changes since 3.0.7:
                    421: 
                    422:   BUG FIXES:
                    423: 
                    424:     - Fixed two buffer-overflow issues: one where a directory path that is
                    425:       exactly MAXPATHLEN was not handled correctly, and one handling a
                    426:       --backup-dir that is extra extra large.
                    427: 
                    428:     - Fixed a data-corruption issue when preserving hard-links without
                    429:       preserving file ownership, and doing deletions either before or during
                    430:       the transfer (CVE-2011-1097).  This fixes some assert errors in the

                    432:       should have matched.
                    433: 
                    434:     - Fixed a potential crash when an rsync daemon has a filter/exclude list
                    435:       and the transfer is using ACLs or xattrs.
                    436: 
                    437:     - Fixed a hang if a really large file is being processed by an rsync that
                    438:       can't handle 64-bit numbers.  Rsync will now complain about the file
                    439:       being too big and skip it.
                    440: 
                    441:     - For devices and special files, we now avoid gathering useless ACL and/or
                    442:       xattr information for files that aren't being copied.  (The un-copied
                    443:       files are still put into the file list, but there's no need to gather
                    444:       data that is not going to be used.)  This ensures that if the user uses
                    445:       --no-D, that rsync can't possibly complain about being unable to gather
                    446:       extended information from special files that are in the file list (but
                    447:       not in the transfer).
                    448: 
                    449:     - Properly handle requesting remote filenames that start with a dash.  This
                    450:       avoids a potential error where a filename could be interpreted as a
                    451:       (usually invalid) option.
                    452: 
                    453:     - Fixed a bug in the comparing of upper-case letters in file suffixes for
                    454:       --skip-compress.
                    455: 
                    456:     - If an rsync daemon has a module configured without a path setting, rsync
                    457:       will now disallow access to that module.
                    458: 
                    459:     - If the destination arg is an empty string, it will be treated as a
                    460:       reference to the current directory (as 2.x used to do).
                    461: 
                    462:     - If rsync was compiled with a newer time-setting function (such as
                    463:       lutimes), rsync will fall-back to an older function (such as utimes) on a
                    464:       system where the newer function is not around.  This helps to make the
                    465:       rsync binary more portable in mixed-OS-release situations.
                    466: 
                    467:     - Fixed a batch-file writing bug that would not write out the full set of
                    468:       compatibility flags that the transfer was using.  This fixes a potential
                    469:       protocol problem for a batch file that contains a sender-side I/O error:
                    470:       it would have been sent in a way that the batch-reader wasn't expecting.
                    471: 
                    472:     - Some improvements to the hard-linking code to ensure that device-number
                    473:       hashing is working right, and to supply more information if the hard-link
                    474:       code fails.
                    475: 
                    476:     - The --inplace code was improved to not search for an impossible checksum
                    477:       position.  The quadruple-verbose chunk[N] message will now mention when
                    478:       an inplace chunk was handled by a seek rather than a read+write.
                    479: 
                    480:     - Improved ACL mask handling, e.g. for Solaris.
                    481: 
                    482:     - Fixed a bug that prevented --numeric-ids from disabling the translation
                    483:       of user/group IDs for ACLs.
                    484: 
                    485:     - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
                    486:       option (e.g. --link-dest) could output an error trying to itemize the
                    487:       changes against the alt-dest directory's xattr/ACL info but was instead
                    488:       trying to access the not-yet-existing new destination directory.
                    489: 
                    490:     - Improved xattr system-error messages to mention the full path to the
                    491:       file.
                    492: 
                    493:     - The --link-dest checking for identical symlinks now avoids considering
                    494:       attribute differences that cannot be changed on the receiver.
                    495: 
                    496:     - Avoid trying to read/write xattrs on certain file types for certain OSes.
                    497:       Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
                    498:       NO_SPECIAL_XATTRS defines in config.h.
                    499: 
                    500:     - Improved the unsafe-symlink errors messages.
                    501: 
                    502:     - Fixed a bug setting xattrs on new files that aren't user writable.
                    503: 
                    504:     - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
                    505: 
                    506:     - Fixed a bug with --fake-super when copying files and dirs that aren't
                    507:       user writable.
                    508: 
                    509:     - Fixed a bug where a sparse file could have its last sparse block turned
                    510:       into a real block when rsync sets the file size (requires ftruncate).
                    511: 
                    512:     - If a temp-file name is too long, rsync now avoids truncating the name in
                    513:       the middle of adjacent high-bit characters.  This prevents a potential
                    514:       filename error if the filesystem doesn't allow a name to contain an
                    515:       invalid multi-byte sequence.
                    516: 
                    517:     - If a muli-protocol socket connection fails (i.e., when contacting a
                    518:       daemon), we now report all the failures, not just the last one.  This
                    519:       avoids losing a relevant error (e.g. an IPv4 connection-refused error)
                    520:       that happened before the final error (e.g. an IPv6 protocol-not-supported
                    521:       error).
                    522: 
                    523:     - Generate a transfer error if we try to call chown with a -1 for a uid or
                    524:       a gid (which is not settable).
                    525: 
                    526:     - Fixed the working of --force when used with --one-file-system.
                    527: 
                    528:     - Fix the popt arg parsing so that an option that doesn't take an arg will
                    529:       reject an attempt to supply one (can configure --with-included-popt if
                    530:       your system's popt library doesn't yet have this fix).
                    531: 
                    532:     - A couple minor option tweaks to the support/rrsync script, and also some
                    533:       regex changes that make vim highlighting happier.
                    534: 
                    535:     - Fixed some issues in the support/mnt-excl script.
                    536: 
                    537:     - Various manpage improvements.
                    538: 
                    539:   ENHANCEMENTS:
                    540: 
                    541:     - Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).
                    542: 
                    543:   DEVELOPER RELATED:
                    544: 
                    545:     - Use lchmod() whenever it is available (not just on symlinks).
                    546: 
                    547:     - A couple fixes to the socketpair_tcp() routine.
                    548: 
                    549:     - Updated the helper scripts in the packaging subdirectory.
                    550: 
                    551:     - Renamed configure.in to configure.ac.
                    552: 
                    553:     - Fixed configure's checking for iconv routines for newer OS X versions.
                    554: 
                    555:     - Fixed the testsuite/xattrs.test script on OS X.

                    557: NEWS for rsync 3.0.7 (31 Dec 2009)
                    558: Protocol: 30 (unchanged)
                    559: Changes since 3.0.6:
                    560: 
                    561:   BUG FIXES:
                    562: 
                    563:     - Fixed a bogus free when using --xattrs with --backup.
                    564: 
                    565:     - Avoid an error when --dry-run  was trying to stat a prior hard-link file
                    566:       that hasn't really been created.
                    567: 
                    568:     - Fixed a problem with --compress (-z) where the receiving side could
                    569:       return the error "inflate (token) returned -5".
                    570: 
                    571:     - Fixed a bug where --delete-during could delete in a directory before it
                    572:       noticed that the sending side sent an I/O error for that directory (both
                    573:       sides of the transfer must be at least 3.0.7).
                    574: 
                    575:     - Improved --skip-compress's error handling of bad character-sets and got
                    576:       rid of a lingering debug fprintf().
                    577: 
                    578:     - Fixed the daemon's conveyance of io_error value from the sender.
                    579: 
                    580:     - An rsync daemon use seteuid() (when available) if it used setuid().
                    581: 
                    582:     - Get the permissions right on a --fake-super transferred directory that
                    583:       needs more owner permissions to emulate root behavior.
                    584: 
                    585:     - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
                    586:       its modifier when sending the filter rules to the remote rsync.
                    587: 
                    588:     - Improved the "--delete does not work without -r or -d" message.
                    589: 
                    590:     - Improved rsync's handling of --timeout to avoid a weird timeout case
                    591:       where the sender could timeout even though it has recently written data
                    592:       to the socket (but hasn't read data recently, due to the writing).
                    593: 
                    594:     - Some misc manpage improvements.
                    595: 
                    596:     - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
                    597: 
                    598:     - Make sure that a timeout specified in the daemon's config is used as a
                    599:       maximum timeout value when the user also specifies a timeout.
                    600: 
                    601:     - Improved the error-exit reporting when rsync gets an error trying to
                    602:       cleanup after an error:  the initial error is reported.
                    603: 
                    604:     - Improved configure's detection of IPv6 for solaris and cygwin.
                    605: 
                    606:     - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
                    607: 
                    608:     - Made our (only used if missing) getaddrinfo() routine use inet_pton()
                    609:       (which we also provide) instead of inet_aton().
                    610: 
                    611:     - The exit-related debug messages now mention the program's role so it is
                    612:       clear who output what message.
                    613:

                    615: 
                    616:     - Got rid of type-punned compiler warnings output by newer gcc versions.
                    617: 
                    618:     - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
                    619: 
                    620:     - The testsuite no longer uses "id -u", so it works better on solaris.

                    625: Changes since 3.0.5:
                    626: 
                    627:   BUG FIXES:
                    628: 
                    629:     - Fixed a --read-batch hang when rsync is reading a batch file that was
                    630:       created from an incremental-recursion transfer.
                    631: 
                    632:     - Fixed the daemon's socket code to handle the simultaneous arrival of
                    633:       multiple connections.
                    634: 
                    635:     - Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
                    636:       have consecutive slashes in the value.
                    637: 
                    638:     - Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
                    639: 
                    640:     - The sender now skips a (bogus) symlink that has a 0-length value, which
                    641:       avoids a transfer error in the receiver.
                    642: 
                    643:     - Fixed a case where the sender could die with a tag-0 error if there was
                    644:       an I/O during the sending of the file list.
                    645: 
                    646:     - Fixed the rrsync script to avoid a server-side problem when -e is at the
                    647:       start of the short options.
                    648: 
                    649:     - Fixed a problem where a vanished directory could turn into an exit code
                    650:       23 instead of the proper exit code 24.

                    652:     - Fixed the --iconv conversion of symlinks when doing a local copy.
                    653: 
                    654:     - Fixed a problem where --one-file-system was not stopping deletions on the

                    661:       rsync to associate the wrong ACL/xattr information with received files.
                    662:

                    671:     - Fixed a run-time issue for systems that can't find iconv_open() by adding
                    672:       the --disable-iconv-open configure option.
                    673: 
                    674:     - Complain and die if the user tries to combine --remove-source-files (or
                    675:       the deprecated --remove-sent-files) with --read-batch.
                    676:

                    682: Changes since 3.0.4:
                    683: 
                    684:   BUG FIXES:
                    685: 
                    686:     - Initialize xattr data in a couple spots in the hlink code, which avoids a
                    687:       crash when the xattr pointer's memory happens to start out non-zero.
                    688:       Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
                    689: 
                    690:     - Don't send a bogus "-" option to an older server if there were no short
                    691:       options specified.
                    692: 
                    693:     - Fixed skipping of unneeded updates in a batch file when incremental
                    694:       recursion is active.  Added a test for this.  Made batch-mode handle
                    695:       "redo" files properly (and without hanging).
                    696: 
                    697:     - Fix the %P logfile escape when the daemon logs from inside a chroot.
                    698: 
                    699:     - Fixed the use of -s (--protect-args) when used with a remote source or
                    700:       destination that had an empty path (e.g. "host:").  Also fixed a problem
                    701:       when -s was used when accessing a daemon via a remote-shell.
                    702: 
                    703:     - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from

                    705: 
                    706:     - Fixed a bug with "-K --delete" removing symlinks to directories when
                    707:       incremental recursion is active.
                    708: 
                    709:     - Fixed a hard to trigger hang when using --remove-source-files.
                    710: 
                    711:     - Got rid of an annoying delay when accessing a daemon via a remote-shell.
                    712: 
                    713:     - Properly ignore (superfluous) source args on a --read-batch command.
                    714: 
                    715:     - Improved the manpage's description of the '*' wildcard to remove the
                    716:       confusing "non-empty" qualifier.
                    717: 
                    718:     - Fixed reverse lookups in the compatibility-library version of
                    719:       getnameinfo().
                    720: 
                    721:     - Fixed a bug when using --sparse on a sparse file that has over 2GB of
                    722:       consecutive sparse data.
                    723: 
                    724:     - Avoid a hang when using at least 3 --verbose options on a transfer with a
                    725:       client sender (which includes local copying).
                    726: 
                    727:     - Fixed a problem with --delete-delay reporting an error when it was ready
                    728:       to remove a directory that was now gone.
                    729: 
                    730:     - Got rid of a bunch of "warn_unused_result" compiler warnings.
                    731: 
                    732:     - If an ftruncate() on a received file fails, it now causes a partial-

                    738: 
                    739:     - Made the support/atomic-rsync script able to perform a fully atomic

                    747: 
                    748:   BUG FIXES:
                    749: 
                    750:     - Fixed a bug in the hard-linking code where it would sometimes try to
                    751:       allocate 0 bytes of memory (which fails on some OSes, such as AIX).
                    752: 
                    753:     - Fixed the hard-linking of files from a device that has a device number
                    754:       of 0 (which seems to be a common device number on NetBSD).
                    755: 
                    756:     - Fixed the handling of a --partial-dir that cannot be created.  This
                    757:       particularly impacts the --delay-updates option (since the files cannot
                    758:       be delayed without a partial-dir), and was potentially destructive if
                    759:       the --remove-source-files was also specified.
                    760: 
                    761:     - Fixed a couple issues in the --fake-super handling of xattrs when the
                    762:       destination files have root-level attributes (e.g. selinux values) that
                    763:       a non-root copy can't affect.
                    764: 
                    765:     - Improved the keep-alive check in the generator to fire consistently in
                    766:       incremental-recursion mode when --timeout is enabled.
                    767: 
                    768:     - The --iconv option now converts the content of a symlink too, instead
                    769:       of leaving it in the wrong character-set (requires 3.0.4 on both sides
                    770:       of the transfer).
                    771: 
                    772:     - When using --iconv, if a filename fails to convert on the receiving side,
                    773:       this no longer makes deletions in the root-dir of the transfer fail
                    774:       silently (the user now gets a warning about deletions being disabled
                    775:       due to IO error as long as --ignore-errors was not specified).
                    776: 
                    777:     - When using --iconv, if a server-side receiver can't convert a filename,
                    778:       the error message sent back to the client no longer mangles the name
                    779:       with the wrong charset conversion.
                    780: 
                    781:     - Fixed a potential alignment issue in the IRIX ACL code when allocating
                    782:       the initial "struct acl" object.  Also, cast mallocs to avoid warnings.
                    783: 
                    784:     - Changed some errors that were going to stdout to go to stderr.
                    785: 
                    786:     - Made human_num() and human_dnum() able to output a negative number
                    787:       (rather than outputting a cryptic string of punctuation).

                    792:       is requested (and thus the option would not be useful).  This lets the
                    793:       user specify the --protocol=29 option to access an overly-restrictive
                    794:       server that is rejecting the protocol-30 use of -e to the server.
                    795: 
                    796:     - Improved the message output for an RERR_PARTIAL exit.

                    801:       or the configure files, only for actual changes in content.
                    802: 
                    803:     - Changed some commands in the testsuite's xattrs.test that called "rsync"

                    827: 
                    828:     - Fixed the combination of --xattrs and --backup.
                    829:

                    834:       files) to a differently named, non-existent directory.
                    835:

                    847:

                    875: 
                    876:     - Added a new script in the support directory, deny-rsync, which allows
                    877:       an admin to (temporarily) replace the rsync command with a script that
                    878:       sends an error message to the remote client via the rsync protocol.

                    884: 
                    885:     - Improved the daemon tests, including checking module comments, the

                    888: 
                    889:     - Improved some build rules for those that build in a separate directory

                    893:

                    924: 
                    925:   NOTABLE CHANGES IN BEHAVIOR:
                    926: 
                    927:     - Added the 'c'-flag to the itemizing of non-regular files so that the
                    928:       itemized output doesn't get hidden if there were no attribute changes,
                    929:       and also so that the itemizing of a --copy-links run will distinguish
                    930:       between copying an identical non-regular file and the creation of a
                    931:       revised version with a new value (e.g. a changed symlink referent, a
                    932:       new device number, etc.).
                    933: 
                    934:   BUG FIXES:
                    935: 
                    936:     - Fixed a crash bug when a single-use rsync daemon (via remote shell) was
                    937:       run without specifying a --config=FILE option.
                    938: 
                    939:     - Fixed a crash when backing up a directory that has a default ACL.
                    940: 
                    941:     - Fixed a bug in the handling of xattr values that could cause rsync to
                    942:       not think that a file's extended attributes are up-to-date.
                    943: 
                    944:     - Fixed the working of --fake-super with --link-dest and --xattrs.
                    945: 
                    946:     - Fixed a hang when combining --dry-run with --remove-source-files.
                    947: 
                    948:     - Fixed a bug with --iconv's handling of files that cannot be converted:
                    949:       a failed name can no longer cause a transfer failure.
                    950: 
                    951:     - Fixed the building of the rounding.h file on systems that need custom
                    952:       CPPFLAGS to be used.  Also improved the error reporting if the building
                    953:       of rounding.h fails.
                    954: 
                    955:     - Fixed the use of the --protect-args (-s) option when talking to a daemon.
                    956: 
                    957:     - Fixed the --ignore-existing option's protection of files on the receiver
                    958:       that are non-regular files on the sender (e.g. if a symlink or a dir on
                    959:       the sender is trying to replace a file on the receiver).  The reverse
                    960:       protection (protecting a dir/symlink/device from being replaced by a
                    961:       file) was already working.
                    962: 
                    963:     - Fixed an assert failure if --hard-links is combined with an option that
                    964:       can skip a file in a set of hard-linked files (i.e. --ignore-existing,
                    965:       --append, etc.), without skipping all the files in the set.
                    966: 
                    967:     - Avoid setting the modify time on a directory that already has the right
                    968:       modify time set.  This avoids tweaking the dir's ctime.
                    969: 
                    970:     - Improved the daemon-exclude handling to do a better job of applying the
                    971:       exclude rules to path entries.  It also sends the user an error just as
                    972:       if the files were actually missing (instead of silently ignoring the
                    973:       user's args), and avoids sending the user the filter-action messages
                    974:       for these non-user-initiated rules.
                    975: 
                    976:     - Fixed some glitches with the dry-run code's missing-directory
                    977:       handling, including a problem when combined with --fuzzy.
                    978: 
                    979:     - Fixed some glitches with the skipped-directory handling.
                    980: 
                    981:     - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
                    982: 
                    983:     - Fixed a glitch in the itemizing of permissions with the -E option.
                    984: 
                    985:     - The --append option's restricting of transfers to those that add data no
                    986:       longer prevents the updating of non-content changes to otherwise up-to-
                    987:       date files (i.e. those with the same content but differing permissions,
                    988:       ownership, xattrs, etc.).
                    989: 
                    990:     - Don't allow --fake-super to be specified with -XX (double --xattrs)
                    991:       because the options conflict.  If a daemon has "fake super" enabled,
                    992:       it automatically downgrades a -XX request to -X.
                    993: 
                    994:     - Fixed a couple bugs in the parsing of daemon-config excludes that could
                    995:       make a floating exclude rule get treated as matching an absolute path.
                    996: 
                    997:     - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
                    998:       wasn't compiled in to the daemon (avoiding a warning in the logs).
                    999: 
                   1000:     - Fixed the inclusion of per-dir merge files from implied dirs.
                   1001: 
                   1002:     - Fixed the support/rrsync script to work with the latest options that
                   1003:       rsync sends (including its flag-specifying use of -e to the server).
                   1004: 
                   1005:   ENHANCEMENTS:
                   1006: 
                   1007:     - Added the --old-dirs (--old-d) option to make it easier for a user to
                   1008:       ask for file-listings with older rsync versions (this is easier than
                   1009:       having to type "-r --exclude='/*/*'" manually).
                   1010: 
                   1011:     - When getting an error while asking an older rsync daemon for a file
                   1012:       listing, rsync will try to notice if the error is a rejection of the
                   1013:       --dirs (-d) option and let the user know how to work around the issue.
                   1014: 
                   1015:     - Added a few more --no-OPTION overrides.
                   1016: 
                   1017:     - Improved the documentation of the --append option.
                   1018: 
                   1019:     - Improved the documentation of the filter/exclude/include daemon
                   1020:       parameters.

                   1023: 
                   1024:     - Fixed a couple minor bugs in the included popt library (ones which I
                   1025:       sent to the official popt project for inclusion in the 1.14 release).
                   1026: 
                   1027:     - Fixed a stat() call that should have been do_stat() so that the proper
                   1028:       normal/64-bit stat() function gets called.  (Was in an area that should
                   1029:       not have caused problems, though.)
                   1030: 
                   1031:     - Changed the file-glob code to do a directory scan without using the
                   1032:       "glob" and "glob.h".  This lets us do the globbing with less memory
                   1033:       churn, and also avoid adding daemon-excluded items to the returned
                   1034:       args.

                   1037: 
                   1038:     - The configure script tries to get the user's compiler to not warn about
                   1039:       unused function parameters if the build is not including one or more of
                   1040:       the ACL/xattrs/iconv features.
                   1041: 
                   1042:     - The configure script now has better checks for figuring out if the
                   1043:       included popt code should be used or not.
                   1044: 
                   1045:     - Fixed two testsuite glitches: avoid a failure if someone's "cd" command
                   1046:       outputs the current directory when cd-ing to a relative path, and made
                   1047:       the itemized test query how rsync was built to determine if it should

                   1049: 
                   1050:     - Updated the testsuite to verify that various bug fixes remain fixed.
                   1051: 
                   1052:     - The RPM spec file was updated to have: (1) comments for how to use the

                   1061: Changes since 2.6.9:
                   1062: 
                   1063:   NOTABLE CHANGES IN BEHAVIOR:
                   1064: 
                   1065:     - The handling of implied directories when using --relative has changed to
                   1066:       send them as directories (e.g. no implied dir is ever sent as a symlink).
                   1067:       This avoids unexpected behavior and should not adversely affect most
                   1068:       people.  If you're one of those rare individuals who relied upon having
                   1069:       an implied dir be duplicated as a symlink, you should specify the
                   1070:       transfer of the symlink and the transfer of the referent directory as
                   1071:       separate args.  (See also --keep-dirlinks and --no-implied-dirs.)
                   1072:       Also, exclude rules no longer have a partial effect on implied dirs.
                   1073: 
                   1074:     - Requesting a remote file-listing without specifying -r (--recursive) now
                   1075:       sends the -d (--dirs) option to the remote rsync rather than sending -r
                   1076:       along with an extra exclude of /*/*.  If the remote rsync does not
                   1077:       understand the -d option (i.e. it is 2.6.3 or older), you will need to
                   1078:       either turn off -d (--no-d), or specify  -r --exclude='/*/*'  manually.
                   1079: 
                   1080:     - In --dry-run mode, the last line of the verbose summary text is output
                   1081:       with a "(DRY RUN)" suffix to help remind you that no updates were made.
                   1082:       Similarly, --only-write-batch outputs "(BATCH ONLY)".
                   1083: 
                   1084:     - A writable rsync daemon with "use chroot" disabled now defaults to a
                   1085:       symlink-munging behavior designed to make symlinks safer while also
                   1086:       allowing absolute symlinks to be stored and retrieved.  This also has
                   1087:       the effect of making symlinks unusable while they're in the daemon's
                   1088:       hierarchy.  See the daemon's "munge symlinks" parameter for details.
                   1089: 
                   1090:     - Starting up an extra copy of an rsync daemon will not clobber the pidfile
                   1091:       for the running daemon -- if the pidfile exists, the new daemon will exit
                   1092:       with an error.  This means that your wrapper script that starts the rsync
                   1093:       daemon should be made to handle lock-breaking (if you want any automatic
                   1094:       breaking of locks to be done).
                   1095: 
                   1096:   BUG FIXES:
                   1097: 
                   1098:     - A daemon with "use chroot = no" and excluded items listed in the daemon
                   1099:       config file now properly checks an absolute-path arg specified for these
                   1100:       options:  --compare-dest, --link-dest, --copy-dest, --partial-dir,
                   1101:       --backup-dir, --temp-dir, and --files-from.
                   1102: 
                   1103:     - A daemon can now be told to disable all user- and group-name translation
                   1104:       on a per-module basis.  This avoids a potential problem with a writable
                   1105:       daemon module that has "use chroot" enabled -- if precautions weren't
                   1106:       taken, a user could try to add a missing library and get rsync to use
                   1107:       it.  This makes rsync safer by default, and more configurable when id-
                   1108:       translation is not desired.  See the daemon's "numeric ids" parameter
                   1109:       for full details.
                   1110: 
                   1111:     - A chroot daemon can now indicate which part of its path should affect the
                   1112:       chroot call, and which part should become an inside-chroot path for the
                   1113:       module.  This allows you to have outside-the-transfer paths (such as for
                   1114:       libraries) even when you enable chroot protection.  The idiom used in the
                   1115:       rsyncd.conf file is:  path = /chroot/dirs/./dirs/inside
                   1116: 
                   1117:     - If a file's data arrived successfully on the receiving side but the
                   1118:       rename of the temporary file to the destination file failed AND the
                   1119:       --remove-source-files (or the deprecated --remove-sent-files) option
                   1120:       was specified, rsync no longer erroneously removes the associated
                   1121:       source file.
                   1122: 
                   1123:     - Fixed the output of -ii when combined with one of the --*-dest options:
                   1124:       it now itemizes all the items, not just the changed ones.
                   1125: 
                   1126:     - Made the output of all file types consistent when using a --*-dest
                   1127:       option.  Prior versions would output too many creation events for
                   1128:       matching items.
                   1129: 
                   1130:     - The code that waits for a child pid now handles being interrupted by a
                   1131:       signal.  This fixes a problem with the pre-xfer exec function not being
                   1132:       able to get the exit status from the script.
                   1133: 
                   1134:     - A negated filter rule (i.e. with a '!' modifier) no longer loses the
                   1135:       negation when sending the filter rules to the remote rsync.
                   1136: 
                   1137:     - Fixed a problem with the --out-format (aka --log-format) option %f:  it
                   1138:       no longer outputs superfluous directory info for a non-daemon rsync.
                   1139: 
                   1140:     - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
                   1141:       files (which includes local copies).  Version 2.6.9 would complete the
                   1142:       copy, but exit with an error when the receiver output its memory stats.
                   1143: 
                   1144:     - If --password-file is used on a non-daemon transfer, rsync now complains
                   1145:       and exits.  This should help users figure out that they can't use this
                   1146:       option to control a remote shell's password prompt.
                   1147: 
                   1148:     - Make sure that directory permissions of a newly-created destination
                   1149:       directory are handled right when --perms is left off.
                   1150: 
                   1151:     - The itemized output of a newly-created destination directory is now
                   1152:       output as a creation event, not a change event.
                   1153: 
                   1154:     - Improved --hard-link so that more corner cases are handled correctly
                   1155:       when combined with options such as --link-dest and/or --ignore-existing.
                   1156: 
                   1157:     - The --append option no longer updates a file that has the same size.
                   1158: 
                   1159:     - Fixed a bug when combining --backup and --backup-dir with --inplace:
                   1160:       any missing backup directories are now created.
                   1161: 
                   1162:     - Fixed a bug when using --backup and --inplace with --whole-file or
                   1163:       --read-batch: backup files are actually created now.
                   1164: 
                   1165:     - The daemon pidfile is checked and created sooner in the startup sequence.
                   1166: 
                   1167:     - If a daemon module's "path" value is not an absolute pathname, the code
                   1168:       now makes it absolute internally (making it work properly).
                   1169: 
                   1170:     - Ensure that a temporary file always has owner-write permission while we
                   1171:       are writing to it.  This avoids problems with some network filesystems
                   1172:       when transfering read-only files.
                   1173: 
                   1174:     - Any errors output about password-file reading no longer cause an error at
                   1175:       the end of the run about a partial transfer.
                   1176: 
                   1177:     - The --read-batch option for protocol 30 now ensures that several more
                   1178:       options are set correctly for the current batch file:  --iconv, --acls,
                   1179:       --xattrs, --inplace, --append, and --append-verify.
                   1180: 
                   1181:     - Using --only-write-batch to a daemon receiver now works properly (older
                   1182:       versions would update some files while writing the batch).
                   1183: 
                   1184:     - Avoid outputting a "file has vanished" message when the file is a broken
                   1185:       symlink and --copy-unsafe-links or --copy-dirlinks is used (the code
                   1186:       already handled this for --copy-links).
                   1187: 
                   1188:     - Fixed the combination of --only-write-batch and --dry-run.
                   1189: 
                   1190:     - Fixed rsync's ability to remove files that are not writable by the file's
                   1191:       owner when rsync is running as the same user.
                   1192: 
                   1193:     - When transferring large files, the sender's hashtable of checksums is
                   1194:       kept at a more reasonable state of fullness (no more than 80% full) so
                   1195:       that the scanning of the hashtable will not bog down as the number of
                   1196:       blocks increases.
                   1197: 
                   1198:   ENHANCEMENTS:
                   1199: 
                   1200:     - A new incremental-recursion algorithm is now used when rsync is talking
                   1201:       to another 3.x version.  This starts the transfer going more quickly
                   1202:       (before all the files have been found), and requires much less memory.
                   1203:       See the --recursive option in the manpage for some restrictions.
                   1204: 
                   1205:     - Lowered memory use in the non-incremental-recursion algorithm for typical
                   1206:       option values (usually saving from 21-29 bytes per file).
                   1207: 
                   1208:     - The default --delete algorithm is now --delete-during when talking to a
                   1209:       3.x rsync.  This is a faster scan than using --delete-before (which is
                   1210:       the default when talking to older rsync versions), and is compatible with
                   1211:       the new incremental recursion mode.
                   1212: 
                   1213:     - Rsync now allows multiple remote-source args to be specified rather than
                   1214:       having to rely on a special space-splitting side-effect of the remote-
                   1215:       shell.  Additional remote args must specify the same host or an empty one
                   1216:       (e.g. empty:  :file1  or  ::module/file2).  For example, this means that
                   1217:       local use of brace expansion now works:  rsync -av host:dir/{f1,f2} .
                   1218: 
                   1219:     - Added the --protect-args (-s) option, that tells rsync to send most of
                   1220:       the command-line args at the start of the transfer rather than as args
                   1221:       to the remote-shell command.  This protects them from space-splitting,
                   1222:       and only interprets basic wildcard special shell characters (*?[).
                   1223: 
                   1224:     - Added the --delete-delay option, which is a more efficient way to delete
                   1225:       files at the end of the transfer without needing a separate delete pass.
                   1226: 
                   1227:     - Added the --acls (-A) option to preserve Access Control Lists.  This is
                   1228:       an improved version of the prior patch that was available, and it even
                   1229:       supports OS X ACLs.  If you need to have backward compatibility with old,
                   1230:       ACL-patched versions of rsync, apply the acls.diff file from the patches
                   1231:       dir.
                   1232: 
                   1233:     - Added the --xattrs (-X) option to preserve extended attributes.  This is
                   1234:       an improved version of the prior patch that was available, and it even
                   1235:       supports OS X xattrs (which includes their resource fork data).  If you
                   1236:       need to have backward compatibility with old, xattr-patched versions of
                   1237:       rsync, apply the xattrs.diff file from the patches dir.
                   1238: 
                   1239:     - Added the --fake-super option that allows a non-super user to preserve
                   1240:       all attributes of a file by using a special extended-attribute idiom.
                   1241:       It even supports the storing of foreign ACL data on your backup server.
                   1242:       There is also an analogous "fake super" parameter for an rsync daemon.
                   1243: 
                   1244:     - Added the --iconv option, which allows rsync to convert filenames from
                   1245:       one character-set to another during the transfer.  The default is to
                   1246:       make this feature available as long as your system has iconv_open().
                   1247:       If compilation fails, specify --disable-iconv to configure, and then
                   1248:       rebuild.  If you want rsync to perform character-set conversions by
                   1249:       default, you can specify --enable-iconv=CONVERT_STRING with the default
                   1250:       value for the --iconv option that you wish to use.  For example,
                   1251:       "--enable-iconv=." is a good choice.  See the rsync manpage for an
                   1252:       explanation of the --iconv option's settings.
                   1253: 
                   1254:     - A new daemon config parameter, "charset", lets you control the character-
                   1255:       set that is used during an --iconv transfer to/from a daemon module.  You
                   1256:       can also set your daemon to refuse "no-iconv" if you want to force the
                   1257:       client to use an --iconv transfer (requiring an rsync 3.x client).
                   1258: 
                   1259:     - Added the --skip-compress=LIST option to override the default list of
                   1260:       file suffixes that will not be compressed when using --compress (-z).
                   1261: 
                   1262:     - The daemon's default for "dont compress" was extended to include:
                   1263:          *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
                   1264:       The name-matching routine was also optimized to run more quickly.
                   1265: 
                   1266:     - The --max-delete option now outputs a warning if it skipped any file
                   1267:       deletions, including a count of how many deletions were skipped.  (Older
                   1268:       versions just silently stopped deleting things.)
                   1269: 
                   1270:     - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
                   1271:       about extraneous files without deleting anything.  If you're not sure
                   1272:       what version the client is, you can use the less-obvious --max-delete=-1,
                   1273:       as both old and new versions will treat that as the same request (though
                   1274:       older versions don't warn).
                   1275: 
                   1276:     - The --hard-link option now uses less memory on both the sending and
                   1277:       receiving side for all protocol versions.  For protocol 30, the use of a
                   1278:       hashtable on the sending side allows us to more efficiently convey to the
                   1279:       receiver what files are linked together.  This reduces the amount of data
                   1280:       sent over the socket by a considerable margin (rather than adding more
                   1281:       data), and limits the in-memory storage of the device+inode information
                   1282:       to just the sending side for the new protocol 30, or to the receiving
                   1283:       side when speaking an older protocol (note that older rsync versions kept
                   1284:       the device+inode information on both sides).
                   1285: 
                   1286:     - The filter rules now support a perishable ("p") modifier that marks rules
                   1287:       that should not have an effect in a directory that is being deleted.  e.g.
                   1288:       -f '-p .svn/' would only affect "live" .svn directories.
                   1289: 
                   1290:     - Rsync checks all the alternate-destination args for validity (e.g.
                   1291:       --link-dest).  This lets the user know when they specified a directory
                   1292:       that does not exist.
                   1293: 
                   1294:     - If we get an ENOSYS error setting the time on a symlink, we don't
                   1295:       complain about it anymore (for those systems that even support the
                   1296:       setting of the modify-time on a symlink).
                   1297: 
                   1298:     - Protocol 30 now uses MD5 checksums instead of MD4.
                   1299: 
                   1300:     - Changed the --append option to not checksum the existing data in the
                   1301:       destination file, which speeds up file appending.
                   1302: 
                   1303:     - Added the --append-verify option, which works like the older --append
                   1304:       option (verifying the existing data in the destination file).  For
                   1305:       compatibility with older rsync versions, any use of --append that is
                   1306:       talking protocol 29 or older will revert to the --append-verify method.
                   1307: 
                   1308:     - Added the --contimeout=SECONDS option that lets the user specify a
                   1309:       connection timeout for rsync daemon access.
                   1310: 
                   1311:     - Documented and extended the support for the RSYNC_CONNECT_PROG variable
                   1312:       that can be used to enhance the client side of a daemon connection.
                   1313: 
                   1314:     - Improved the dashes and double-quotes in the nroff manpage output.
                   1315: 
                   1316:     - Rsync now supports a lot more --no-OPTION override options.
                   1317: 
                   1318:   INTERNAL:
                   1319: 
                   1320:     - The file-list sorting algorithm now uses a sort that keeps any same-
                   1321:       named items in the same order as they were specified.  This allows
                   1322:       rsync to always ensure that the first of the duplicates is the one
                   1323:       that will be included in the copy.  The new sort is also faster
                   1324:       than the glibc version of qsort() and mergesort().
                   1325: 
                   1326:     - Rsync now supports the transfer of 64-bit timestamps (time_t values).
                   1327: 
                   1328:     - Made the file-deletion code use a little less stack when recursing
                   1329:       through a directory hierarchy of extraneous files.
                   1330: 
                   1331:     - Fixed a build problem with older (2.x) versions of gcc.
                   1332: 
                   1333:     - Added some isType() functions that make dealing with signed characters
                   1334:       easier without forcing variables via casts.
                   1335: 
                   1336:     - Changed strcat/strcpy/sprintf function calls to use safer versions.
                   1337: 
                   1338:     - Upgraded the included popt version to 1.10.2 and improved its use of
                   1339:       string-handling functions.
                   1340: 
                   1341:     - Added missing prototypes for compatibility functions from the lib dir.
                   1342: 
                   1343:     - Configure determines if iconv() has a const arg, allowing us to avoid a
                   1344:       compiler warning.
                   1345: 
                   1346:     - Made the sending of some numbers more efficient for protocol 30.
                   1347: 
                   1348:     - Make sure that a daemon process doesn't mind if the client was weird and
                   1349:       omitted the --server option.
                   1350: 
                   1351:     - There are more internal logging categories available in protocol 30 than
                   1352:       the age-old FINFO and FERROR, including FERROR_XFER and FWARN.  These new
                   1353:       categories allow some errors and warnings to go to stderr without causing
                   1354:       an erroneous end-of-run warning about some files not being able to be
                   1355:       transferred.
                   1356: 
                   1357:     - Improved the use of "const" on pointers.
                   1358: 
                   1359:     - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
                   1360:       older sections of a pool's memory.
                   1361: 
                   1362:     - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
                   1363:       some new code (derived from samba, derived from PostgreSQL) that has a
                   1364:       better license than the old code.
                   1365: 
                   1366:   DEVELOPER RELATED:
                   1367: 
                   1368:     - Rsync is now licensed under the GPLv3 or later.
                   1369: 
                   1370:     - Rsync is now being maintained in a "git" repository instead of CVS
                   1371:       (though the old CVS repository still exists for historical access).
                   1372:       Several maintenance scripts were updated to work with git.
                   1373: 
                   1374:     - Generated files are no longer committed into the source repository.  The
                   1375:       autoconf and autoheader commands are now automatically run during the
                   1376:       normal use of "configure" and "make".  The latest dev versions of all
                   1377:       generated files can also be copied from the samba.org web site (see the
                   1378:       prepare-source script's fetch option).
                   1379: 
                   1380:     - The "patches" directory of diff files is now built from branches in the
                   1381:       rsync git repository (branch patch/FOO creates file patches/FOO.diff).
                   1382:       This directory is now distributed in a separate separate tar file named
                   1383:       rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
                   1384: 
                   1385:     - The proto.h file is now built using a simple perl script rather than a
                   1386:       complex awk script, which proved to be more widely compatible.
                   1387: 
                   1388:     - When running the tests, we now put our per-test temp dirs into a sub-
                   1389:       directory named testtmp (which is created, if missing).  This allows
                   1390:       someone to symlink the testtmp directory to another filesystem (which is
                   1391:       useful if the build dir's filesystem does not support ACLs and xattrs,
                   1392:       but another filesystem does).
                   1393: 
                   1394:     - Rsync now has a way of handling protocol-version changes during the
                   1395:       development of a new protocol version.  This causes any out-of-sync
                   1396:       versions to speak an older protocol rather than fail in a cryptic manner.
                   1397:       This addition makes it safer to deploy a pre-release version that may
                   1398:       interact with the public.  This new exchange of sub-version info does not
                   1399:       interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
                   1400:       does not have enough range to allow the main protocol number to be
                   1401:       incremented for every minor tweak in that happens during development).
                   1402: 
                   1403:     - The csprotocol.txt file was updated to mention the daemon protocol change
                   1404:       in the 3.0.0 release.
                   1405:

                   1407: NEWS for rsync 2.6.9 (6 Nov 2006)
                   1408: Protocol: 29 (unchanged)
                   1409: Changes since 2.6.8:
                   1410: 
                   1411:   BUG FIXES:
                   1412: 
                   1413:     - If rsync is interrupted via a handled signal (such as SIGINT), it will
                   1414:       once again clean-up its temp file from the destination dir.
                   1415: 
                   1416:     - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
                   1417:       --copy-dest, and --compare-dest options to a daemon without chroot: if
                   1418:       the copy's destination dir is deeper than the top of the module's path,
                   1419:       these options now accept a safe number of parent-dir (../) references
                   1420:       (since these options are relative to the destination dir).  The old code
                   1421:       incorrectly chopped off all "../" prefixes for these options, no matter
                   1422:       how deep the destination directory was in the module's hierarchy.
                   1423: 
                   1424:     - Fixed a bug where a deferred info/error/log message could get sent
                   1425:       directly to the sender instead of being handled by rwrite() in the
                   1426:       generator.  This fixes an "unexpected tag 3" fatal error, and should
                   1427:       also fix a potential problem where a deferred info/error message from
                   1428:       the receiver might bypass the log file and get sent only to the client
                   1429:       process.  (These problems could only affect an rsync daemon that was
                   1430:       receiving files.)
                   1431: 
                   1432:     - Fixed a bug when --inplace was combined with a --*-dest option and we
                   1433:       update a file's data using an alternate basis file.  The code now
                   1434:       notices that it needs to copy the matching data from the basis file
                   1435:       instead of (wrongly) assuming that it was already present in the file.
                   1436: 
                   1437:     - Fixed a bug where using --dry-run with a --*-dest option with a path
                   1438:       relative to a directory that does not yet exist:  the affected option
                   1439:       gets its proper path value so that the output of the dry-run is right.
                   1440: 
                   1441:     - Fixed a bug in the %f logfile escape when receiving files: the
                   1442:       destination path is now included in the output (e.g. you can now tell
                   1443:       when a user specifies a subdir inside a module).
                   1444: 
                   1445:     - If the receiving side fails to create a directory, it will now skip
                   1446:       trying to update everything that is inside that directory.
                   1447: 
                   1448:     - If --link-dest is specified with --checksum but without --times, rsync
                   1449:       will now allow a hard-link to be created to a matching link-dest file
                   1450:       even when the file's modify-time doesn't match the server's file.
                   1451: 
                   1452:     - The daemon now calls more timezone-using functions prior to doing a
                   1453:       chroot.  This should help some C libraries to generate proper timestamps
                   1454:       from inside a chrooted daemon (and to not try to access /etc/timezone
                   1455:       over and over again).
                   1456: 
                   1457:     - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
                   1458:       it now deletes an alternate basis file from the partial-dir that was used
                   1459:       to successfully update a destination file.
                   1460: 
                   1461:     - Fixed a bug in the handling of --delete-excluded when using a per-dir
                   1462:       merge file:  the merge file is now honored on the receiving side, and
                   1463:       only its unqualified include/exclude commands are ignored (just as is
                   1464:       done for global include/excludes).
                   1465: 
                   1466:     - Fixed a recent bug where --delete was not working when transferring from
                   1467:       the root (/) of the filesystem with --relative enabled.
                   1468: 
                   1469:     - Fixed a recent bug where an --exclude='*' could affect the root (/) of
                   1470:       the filesystem with --relative enabled.
                   1471: 
                   1472:     - When --inplace creates a file, it is now created with owner read/write
                   1473:       permissions (0600) instead of no permissions at all.  This avoids a
                   1474:       problem continuing a transfer that was interrupted (since --inplace
                   1475:       will not update a file that has no write permissions).
                   1476: 
                   1477:     - If either --remove-source-files or --remove-sent-files is enabled and we
                   1478:       are unable to remove the source file, rsync now outputs an error.
                   1479: 
                   1480:     - Fixed a bug in the daemon's "incoming chmod" rule:  newly-created
                   1481:       directories no longer get the 'F' (file) rules applied to them.
                   1482: 
                   1483:     - Fixed an infinite loop bug when a filter rule was rejected due to being
                   1484:       overly long.
                   1485: 
                   1486:     - When the server receives a --partial-dir option from the client, it no
                   1487:       longer runs the client-side code that adds an assumed filter rule (since
                   1488:       the client will be sending us the rules in the usual manner, and they
                   1489:       may have chosen to override the auto-added rule).
                   1490: 
                   1491:   ENHANCEMENTS:
                   1492: 
                   1493:     - Added the --log-file=FILE and --log-file-format=FORMAT options.  These
                   1494:       can be used to tell any rsync to output what it is doing to a log file.
                   1495:       They work with a client rsync, a non-daemon server rsync (see the man
                   1496:       page for instructions), and also allows the overriding of rsyncd.conf
                   1497:       settings when starting a daemon.
                   1498: 
                   1499:     - The --log-format option was renamed to be --out-format to avoid confusing
                   1500:       it with affecting the log-file output.  (The old option remains as an
                   1501:       alias for the new to preserve backward compatibility.)
                   1502: 
                   1503:     - Made "log file" and "syslog facility" settable on a per-module basis in
                   1504:       the daemon's config file.
                   1505: 
                   1506:     - Added the --remove-source-files option as a replacement for the (now
                   1507:       deprecated) --remove-sent-files option.  This new option removes all
                   1508:       non-dirs from the source directories, even if the file was already
                   1509:       up-to-date.  This fixes a problem where interrupting an rsync that
                   1510:       was using --remove-sent-files and restarting it could leave behind
                   1511:       a file that the earlier rsync synchronized, but didn't get to remove.
                   1512:       (The deprecated --remove-sent-files is still understood for now, and
                   1513:       still behaves in the same way as before.)
                   1514: 
                   1515:     - Added the option --no-motd to suppress the message-of-the-day output
                   1516:       from a daemon when doing a copy.  (See the manpage for a caveat.)
                   1517: 
                   1518:     - Added a new environment variable to the pre-/post-xfer exec commands (in
                   1519:       the daemon's config file):  RSYNC_PID.  This value will be the same in
                   1520:       both the pre- and post-xfer commands, so it can be used as a unique ID
                   1521:       if the pre-xfer command wants to cache some arg/request info for the
                   1522:       post-xfer command.
                   1523: 
                   1524:   INTERNAL:
                   1525: 
                   1526:     - Did a code audit using IBM's code-checker program and made several
                   1527:       changes, including: replacing most of the strcpy() and sprintf()
                   1528:       calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
                   1529:       an enum that had been intermingling a literal 0 with the defined enum
                   1530:       values, silencing some uninitialized memory checks, marking some
                   1531:       functions with a "noreturn" attribute, and changing an "if" that
                   1532:       could never succeed on some platforms into a pre-processor directive
                   1533:       that conditionally compiles the code.
                   1534: 
                   1535:     - Fixed a potential bug in f_name_cmp() when both the args are a
                   1536:       top-level "." dir (which doesn't happen in normal operations).
                   1537: 
                   1538:     - Changed exit_cleanup() so that it can never return instead of exit.
                   1539:       The old code might return if it found the exit_cleanup() function
                   1540:       was being called recursively.  The new code is segmented so that
                   1541:       any recursive calls move on to the next step of the exit-processing.
                   1542: 
                   1543:     - The macro WIFEXITED(stat) will now be defined if the OS didn't already
                   1544:       define it.
                   1545: 
                   1546:   DEVELOPER RELATED:
                   1547: 
                   1548:     - The acls.diff and xattrs.diff patches have received a bunch of work to
                   1549:       make them much closer to being acceptable in the main distribution.
                   1550:       The xattrs patch also has some preliminary Mac OS X and FreeBSD
                   1551:       compatibility code that various system types to exchange extended
                   1552:       file-attributes.
                   1553: 
                   1554:     - A new diff in the patches dir, fake-root.diff, allows rsync to
                   1555:       maintain a backup hierarchy with full owner, group, and device info
                   1556:       without actually running as root.  It does this using a special
                   1557:       extended attribute, so it depends on xattrs.diff (which depends on
                   1558:       acls.diff).
                   1559: 
                   1560:     - The rsync.yo and rsyncd.conf.yo files have been updated to work
                   1561:       better with the latest yodl 2.x releases.
                   1562: 
                   1563:     - Updated config.guess and config.sub to their 2006-07-02 versions.
                   1564: 
                   1565:     - Updated various files to include the latest FSF address and to have
                   1566:       consistent opening comments.
                   1567:

                   1569: NEWS for rsync 2.6.8 (22 Apr 2006)
                   1570: Protocol: 29 (unchanged)
                   1571: Changes since 2.6.7:
                   1572: 
                   1573:   BUG FIXES:
                   1574: 
                   1575:     - Fixed a bug in the exclude code where an anchored exclude without any
                   1576:       wildcards fails to match an absolute source arg, but only when --relative
                   1577:       is in effect.
                   1578: 
                   1579:     - Improved the I/O code for the generator to fix a potential hang when the
                   1580:       receiver gets an EOF on the socket but the generator's select() call
                   1581:       never indicates that the socket is writable for it to be notified about
                   1582:       the EOF.  (This can happen when using stunnel).
                   1583: 
                   1584:     - Fixed a problem with the file-reading code where a failed read (such as
                   1585:       that caused by a bad sector) would not advance the file's read-position
                   1586:       beyond the failed read's data.
                   1587: 
                   1588:     - Fixed a logging bug where the "log file" directive was not being honored
                   1589:       in a single-use daemon (one spawned by a remote-shell connection or by
                   1590:       init).
                   1591: 
                   1592:     - If rsync cannot honor the --delete option, we output an error and exit
                   1593:       instead of silently ignoring the option.
                   1594: 
                   1595:     - Fixed a bug in the --link-dest code that prevented special files (such as
                   1596:       fifos) from being linked.
                   1597: 
                   1598:     - The ability to hard-link symlinks and special files is now determined at
                   1599:       configure time instead of at runtime.  This fixes a bug with --link-dest
                   1600:       creating a hard-link to a symlink's referent on a BSD system.
                   1601: 
                   1602:   ENHANCEMENTS:
                   1603: 
                   1604:     - In daemon mode, if rsync fails to bind to the requested port, the
                   1605:       error(s) returned by socket() and/or bind() are now logged.
                   1606: 
                   1607:     - When we output a fatal error, we now output the version of rsync in the
                   1608:       message.
                   1609: 
                   1610:     - Improved the documentation for the --owner and --group options.
                   1611: 
                   1612:     - The rsyncstats script in "support" has an improved line-parsing regex
                   1613:       that is easier to read and also makes it to parse syslog-generated lines.
                   1614: 
                   1615:     - A new script in "support": file-attr-restore, can be used to restore the
                   1616:       attributes of a file-set (the permissions, ownership, and group info)
                   1617:       taken from the cached output of a "find ARG... -ls" command.
                   1618: 
                   1619:   DEVELOPER RELATED:
                   1620: 
                   1621:     - Removed the unused function write_int_named(), the unused variable
                   1622:       io_read_phase, and the rarely used variable io_write_phase.  This also
                   1623:       elides the confusing 'phase "unknown"' part of one error message.
                   1624: 
                   1625:     - Removed two unused configure checks and two related (also unused)
                   1626:       compatibility functions.
                   1627: 
                   1628:     - The xattrs.diff patch received a security fix that prevents a potential
                   1629:       buffer overflow in the receive_xattr() code.
                   1630: 
                   1631:     - The acls.diff patch has been improved quite a bit, with more to come.
                   1632: 
                   1633:     - A new patch was added: log-file.diff.  This contains an early version of
                   1634:       a future option, --log-file=FILE, that will allow any rsync to log its
                   1635:       actions to a file (something that only a daemon supports at present).

                   1638: NEWS for rsync 2.6.7 (11 Mar 2006)
                   1639: Protocol: 29 (unchanged)
                   1640: Changes since 2.6.6:
                   1641: 
                   1642:   OUTPUT CHANGES:
                   1643: 
                   1644:     - The letter 'D' in the itemized output was being used for both devices
                   1645:       (character or block) as well as other special files (such as fifos and
                   1646:       named sockets).  This has changed to separate non-device special files
                   1647:       under the 'S' designation (e.g. "cS+++++++ path/fifo").  See also the
                   1648:       "--specials" option, below.
                   1649: 
                   1650:     - The way rsync escapes unreadable characters has changed.  First, rsync
                   1651:       now has support for recognizing valid multibyte character sequences in
                   1652:       your current locale, allowing it to escape fewer characters than before
                   1653:       for a locale such as UTF-8.  Second, it now uses an escape idiom of
                   1654:       "\#123", which is the literal string "\#" followed by exactly 3 octal
                   1655:       digits.  Rsync no longer doubles a backslash character in a filename
                   1656:       (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
                   1657:       escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
                   1658:       (e.g. it will output "foo\#134#789" when copying "foo\#789").  See also
                   1659:       the --8-bit-output (-8) option, mentioned below.
                   1660: 
                   1661:       Script writers: the local rsync is the one that outputs escaped names,
                   1662:       so if you need to support unescaping of filenames for older rsyncs, I'd
                   1663:       suggest that you parse the output of "rsync --version" and only use the
                   1664:       old unescaping rules for 2.6.5 and 2.6.6.
                   1665: 
                   1666:   BUG FIXES:
                   1667: 
                   1668:     - Fixed a really old bug that caused --checksum (-c) to checksum all the
                   1669:       files encountered during the delete scan (ouch).
                   1670: 
                   1671:     - Fixed a potential hang in a remote generator:  when the receiver gets a
                   1672:       read-error on the socket, it now signals the generator about this so that
                   1673:       the generator does not try to send any of the terminating error messages
                   1674:       to the client (avoiding a potential hang in some setups).
                   1675: 
                   1676:     - Made hard-links work with symlinks and devices again.
                   1677: 
                   1678:     - If the sender gets an early EOF reading a source file, we propagate this
                   1679:       error to the receiver so that it can discard the file and try requesting
                   1680:       it again (which is the existing behavior for other kinds of read errors).
                   1681: 
                   1682:     - If a device-file/special-file changes permissions, rsync now updates the
                   1683:       permissions without recreating the file.
                   1684: 
                   1685:     - If the user specifies a remote-host for both the source and destination,
                   1686:       we now output a syntax error rather than trying to open the destination
                   1687:       hostspec as a filename.
                   1688: 
                   1689:     - When --inplace creates a new destination file, rsync now creates it with
                   1690:       permissions 0600 instead of 0000 -- this makes restarting possible when
                   1691:       the transfer gets interrupted in the middle of sending a new file.
                   1692: 
                   1693:     - Reject the combination of --inplace and --sparse since the sparse-output
                   1694:       algorithm doesn't work when overwriting existing data.
                   1695: 
                   1696:     - Fixed the directory name in the error that is output when pop_dir()
                   1697:       fails.
                   1698: 
                   1699:     - Really fixed the parsing of a "!" entry in .cvsignore files this time.
                   1700: 
                   1701:     - If the generator gets a stat() error on a file, output it (this used to
                   1702:       require at least -vv for the error to be seen).
                   1703: 
                   1704:     - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
                   1705:       the exit status properly and generate a better error.
                   1706: 
                   1707:     - Fixed some glitches in the double-verbose output when using --copy-dest,
                   1708:       --link-dest, or --compare-dest.  Also improved how the verbose output
                   1709:       handles hard-links (within the transfer) that had an up-to-date alternate
                   1710:       "dest" file, and copied files (via --copy-dest).
                   1711: 
                   1712:     - Fixed the matching of the dont-compress items (e.g. *.gz) against files
                   1713:       that have a path component containing a slash.
                   1714: 
                   1715:     - If the code reading a filter/exclude file gets an EINTR error, rsync now
                   1716:       clears the error flag on the file handle so it can keep on reading.
                   1717: 
                   1718:     - If --relative is active, the sending side cleans up trailing "/" or "/."
                   1719:       suffixes to avoid triggering a bug in older rsync versions.  Also, we now
                   1720:       reject a ".." dir if it would be sent as a relative dir.
                   1721: 
                   1722:     - If a non-directory is in the way of a directory and rsync is run with
                   1723:       --dry-run and --delete, rsync no longer complains about not being able
                   1724:       to opendir() the not-yet present directory.
                   1725: 
                   1726:     - When --list-only is used and a non-existent local destination dir was
                   1727:       also specified as a destination, rsync no longer generates a warning
                   1728:       about being unable to create the missing directory.
                   1729: 
                   1730:     - Fixed some problems with --relative --no-implied-dirs when the
                   1731:       destination directory did not yet exist:  we can now create a symlink or
                   1732:       device when it is the first thing in the missing dir, and --fuzzy no
                   1733:       longer complains about being unable to open the missing dir.
                   1734: 
                   1735:     - Fixed a bug where the --copy-links option would not affect implied
                   1736:       directories without --copy-unsafe-links (see --relative).
                   1737: 
                   1738:     - Got rid of the need for --force to be used in some circumstances with
                   1739:       --delete-after (making it consistent with --delete-before/-during).
                   1740: 
                   1741:     - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
                   1742:       when a file is too large (rsync handles the write error).
                   1743: 
                   1744:     - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
                   1745:       was not properly padded with trailing '=' chars.  This only affects a
                   1746:       user that need to use a password-authenticated proxy for an outgoing
                   1747:       daemon-rsync connection.
                   1748: 
                   1749:     - If we're transferring an empty directory to a new name, rsync no longer
                   1750:       forces S_IWUSR if it wasn't already set, nor does it accidentally leave
                   1751:       it set.
                   1752: 
                   1753:     - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
                   1754:       checksum for the current file offset.
                   1755: 
                   1756:     - Rsync no longer allows a single directory to be copied over a non-
                   1757:       directory destination arg.
                   1758: 
                   1759:   ENHANCEMENTS:
                   1760: 
                   1761:     - Added the --append option that makes rsync append data onto files that
                   1762:       are longer on the source than the destination (this includes new files).
                   1763: 
                   1764:     - Added the --min-size=SIZE option to exclude small files from the
                   1765:       transfer.
                   1766: 
                   1767:     - Added the --compress-level option to allow you to set how aggressive
                   1768:       rsync's compression should be (this option implies --compress).
                   1769: 
                   1770:     - Enhanced the parsing of the SIZE value for --min-size and --max-size to
                   1771:       allow easy entry of multiples of 1000 (instead of just multiples of 1024)
                   1772:       and off-by-one values too (e.g. --max-size=8mb-1).
                   1773: 
                   1774:     - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
                   1775:       high-bit characters that it thinks are unreadable in the current locale.
                   1776: 
                   1777:     - The new option --human-readable (-h) changes the output of --progress,
                   1778:       --stats, and the end-of-run summary to be easier to read.  If repeated,
                   1779:       the units become powers of 1024 instead of powers of 1000.  (The old
                   1780:       meaning of -h, as a shorthand for --help, still works as long as you
                   1781:       just use it on its own, as in "rsync -h".)
                   1782: 
                   1783:     - If lutimes() and/or lchmod() are around, use them to allow the
                   1784:       preservation of attributes on symlinks.
                   1785: 
                   1786:     - The --link-dest option now affects symlinks and devices (when possible).
                   1787: 
                   1788:     - Added two config items to the rsyncd.conf parsing:  "pre-xfer exec" and
                   1789:       "post-xfer exec".  These allow a command to be specified on a per-module
                   1790:       basis that will be run before and/or after a daemon-mode transfer.  (See
                   1791:       the man page for a list of the environment variables that are set with
                   1792:       information about the transfer.)
                   1793: 
                   1794:     - When using the --relative option, you can now insert a dot dir in
                   1795:       the source path to indicate where the replication of the source dirs
                   1796:       should start.  For example, if you specify a source path of
                   1797:       rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
                   1798:       replicate the "baz/dir" part of the source path (note: a trailing
                   1799:       dot dir is unaffected unless it also has a trailing slash).
                   1800: 
                   1801:     - Added some new --no-FOO options that make it easier to override unwanted
                   1802:       implied or default options.  For example, "-a --no-o" (aka "--archive
                   1803:       --no-owner") can be used to turn off the preservation of file ownership
                   1804:       that is implied by -a.
                   1805: 
                   1806:     - Added the --chmod=MODE option that allows the destination permissions to
                   1807:       be changed from the source permissions.  E.g. --chmod=g+w,o-rwx
                   1808: 
                   1809:     - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
                   1810:       a module to specify what permissions changes should be applied to all
                   1811:       files copied to and from the daemon.
                   1812: 
                   1813:     - Allow the --temp-dir option to be specified when starting a daemon, which
                   1814:       sets the default temporary directory for incoming files.
                   1815: 
                   1816:     - If --delete is combined with --dirs without --recursive, rsync will now
                   1817:       delete in any directory whose content is being synchronized.
                   1818: 
                   1819:     - If --backup is combined with --delete without --backup-dir (and without
                   1820:       --delete-excluded), we add a "protect" filter-rule to ensure that files
                   1821:       with the backup suffix are not deleted.
                   1822: 
                   1823:     - The file-count stats that are output by --progress were improved to
                   1824:       better indicate what the numbers mean.  For instance, the output:
                   1825:       "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
                   1826:       to be transferred, and we still need to check 8383 more files out of
                   1827:       a total of 9999.
                   1828: 
                   1829:     - The include/exclude code now allows a dir/*** directive (with 3 trailing
                   1830:       stars) to match both the dir itself as well as all the content below the
                   1831:       dir (dir/** would not match the dir).
                   1832: 
                   1833:     - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
                   1834:       discard empty chains of directories from the file-list.  This makes it
                   1835:       easier to selectively copy files from a source hierarchy and end up with
                   1836:       just the directories needed to hold the resulting files.
                   1837: 
                   1838:     - If the --itemize-changes (-i) option is repeated, rsync now includes
                   1839:       unchanged files in the itemized output (similar to -vv, but without all
                   1840:       the other verbose messages that can get in the way).  Of course, the
                   1841:       client must be version 2.6.7 for this to work, but the remote rsync only
                   1842:       needs to be 2.6.7 if you're pushing files.
                   1843: 
                   1844:     - Added the --specials option to tell rsync to copy non-device special
                   1845:       files (which rsync now attempts even as a normal user).  The --devices
                   1846:       option now requests the copying of just devices (character and block).
                   1847:       The -D option still requests both (e.g. --devices and --specials), -a
                   1848:       still implies -D, and non-root users still get a silent downgrade that
                   1849:       omits device copying.
                   1850: 
                   1851:     - Added the --super option to make the receiver always attempt super-user
                   1852:       activities.  This is useful for systems that allow things such as devices
                   1853:       to be created or ownership to be set without being UID 0, and is also
                   1854:       useful for someone who wants to ensure that errors will be output if the
                   1855:       receiving rsync isn't being run as root.
                   1856: 
                   1857:     - Added the --sockopts option for those few who want to customize the TCP
                   1858:       options used to contact a daemon rsync.
                   1859: 
                   1860:     - Added a way for the --temp-dir option to be combined with a partial-dir
                   1861:       setting that lets rsync avoid non-atomic updates (for those times when
                   1862:       --temp-dir is not being used because space is tight).
                   1863: 
                   1864:     - A new support script, files-to-excludes, will transform a list of files
                   1865:       into a set of include/exclude directives that will copy those files.
                   1866: 
                   1867:     - A new option, --executability (-E) can be used to preserve just the
                   1868:       execute bit on files, for those times when using the --perms option is
                   1869:       not desired.
                   1870: 
                   1871:     - The daemon now logs each connection and also each module-list request
                   1872:       that it receives.
                   1873: 
                   1874:     - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
                   1875:       (permission bits, e.g. "rwxr-xrwt").
                   1876: 
                   1877:     - The --dry-run option no longer forces the enabling of --verbose.
                   1878: 
                   1879:     - The --remove-sent-files option now does a better job of incrementally
                   1880:       removing the sent files on the sending side (older versions tended to
                   1881:       clump up all the removals at the end).
                   1882: 
                   1883:     - A daemon now supersedes its minimal SIGCHLD handler with the standard
                   1884:       PID-remembering version after forking.  This ensures that the generator
                   1885:       can get the child-exit status from the receiver.
                   1886: 
                   1887:     - Use of the --bwlimit option no longer interferes with the remote rsync
                   1888:       sending error messages about invalid/refused options.
                   1889: 
                   1890:     - Rsync no longer returns a usage error when used with one local source arg
                   1891:       and no destination: this now implies the --list-only option, just like
                   1892:       the comparable situation with a remote source arg.
                   1893: 
                   1894:     - Added the --copy-dirlinks option, a more limited version of --copy-links.
                   1895: 
                   1896:     - Various documentation improvements, including: a better synopsis, some
                   1897:       improved examples, a better discussion of the presence and absence of
                   1898:       --perms (including how it interacts with the new --executability and
                   1899:       --chmod options), an extended discussion of --temp-dir, an improved
                   1900:       discussion of --partial-dir, a better description of rsync's pattern
                   1901:       matching characters, an improved --no-implied-dirs section, and the
                   1902:       documenting of what the --stats option outputs.
                   1903: 
                   1904:     - Various new and updated diffs in the patches dir, including: acls.diff,
                   1905:       xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
                   1906: 
                   1907:   INTERNAL:
                   1908: 
                   1909:     - We now use sigaction() and sigprocmask() if possible, and fall back on
                   1910:       signal() if not.  Using sigprocmask() ensures that rsync enables all the
                   1911:       signals that it needs, just in case it was started in a masked state.
                   1912: 
                   1913:     - Some buffer sizes were expanded a bit, particularly on systems where
                   1914:       MAXPATHLEN is overly small (e.g. cygwin).
                   1915: 
                   1916:     - If io_printf() tries to format more data than fits in the buffer, exit
                   1917:       with an error instead of transmitting a truncated buffer.
                   1918: 
                   1919:     - If a va_copy macro is defined, lib/snprintf.c will use it when defining
                   1920:       the VA_COPY macro.
                   1921: 
                   1922:     - Reduced the amount of stack memory needed for each level of directory
                   1923:       recursion by nearly MAXPATHLEN bytes.
                   1924: 
                   1925:     - The wildmatch function was extended to allow an array of strings to be
                   1926:       supplied as the string to match.  This allows the exclude code to do less
                   1927:       string copying.
                   1928: 
                   1929:     - Got rid of the safe_fname() function (and all the myriad calls) and
                   1930:       replaced it with a new function in the log.c code that filters all the
                   1931:       output going to the terminal.
                   1932: 
                   1933:     - Unified the f_name() and the f_name_to() functions.
                   1934: 
                   1935:     - Improved the hash-table code the sender uses to handle checksums to make
                   1936:       it use slightly less memory and run just a little faster.
                   1937: 
                   1938:   DEVELOPER RELATED:
                   1939: 
                   1940:     - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
                   1941:       the previous -p0.  Also, the version included in the release tar now
                   1942:       affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
                   1943:       it is no longer necessary to run autoconf and/or yodl unless you're
                   1944:       applying a patch that was checked out from CVS.
                   1945: 
                   1946:     - Several diffs in the patches dir now use the proper --enable-FOO
                   1947:       configure option instead of --with-FOO to turn on the inclusion of
                   1948:       the newly patched feature.
                   1949: 
                   1950:     - There is a new script, "prepare-source" than can be used to update the
                   1951:       various generated files (proto.h, configure, etc.) even before configure
                   1952:       has created the Makefile (this is mainly useful when patching the source
                   1953:       with a patch that doesn't affect generated files).
                   1954: 
                   1955:     - The testsuite now sets HOME so that it won't be affected by a file such
                   1956:       as ~/.popt.

                   1959: NEWS for rsync 2.6.6 (28 Jul 2005)
                   1960: Protocol: 29 (unchanged)
                   1961: Changes since 2.6.5:
                   1962: 
                   1963:   SECURITY FIXES:
                   1964: 
                   1965:     - The zlib code was upgraded to version 1.2.3 in order to make it more
                   1966:       secure.  While the widely-publicized security problem in zlib 1.2.2 did
                   1967:       not affect rsync, another security problem surfaced that affects rsync's
                   1968:       zlib 1.1.4.
                   1969: 
                   1970:   BUG FIXES:
                   1971: 
                   1972:     - The setting of flist->high in clean_flist() was wrong for an empty list.
                   1973:       This could cause flist_find() to crash in certain rare circumstances
                   1974:       (e.g. if just the right directory setup was around when --fuzzy was
                   1975:       combined with --link-dest).
                   1976: 
                   1977:     - The outputting of hard-linked files when verbosity was > 1 was not right:
                   1978:       (1) Without -i it would output the name of each hard-linked file as
                   1979:       though it had been changed; it now outputs a "is hard linked" message for
                   1980:       the file. (2) With -i it would output all dots for the unchanged
                   1981:       attributes of a hard-link; it now changes those dots to spaces, as is
                   1982:       done for other totally unchanged items.
                   1983: 
                   1984:     - When backing up a changed symlink or device, get rid of any old backup
                   1985:       item so that we don't get an "already exists" error.
                   1986: 
                   1987:     - A couple places that were comparing a local and a remote modification-
                   1988:       time were not honoring the --modify-window option.
                   1989: 
                   1990:     - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
                   1991:       set too often (if some non-significant mode bits differed).
                   1992: 
                   1993:     - Fixed a really old, minor bug that could cause rsync to warn about being
                   1994:       unable to mkdir() a path that ends in "/." because it just created the
                   1995:       directory (required --relative, --no-implied-dirs, a source path that
                   1996:       ended in either a trailing slash or a trailing "/.", and a non-existing
                   1997:       destination dir to tickle the bug in a recent version).
                   1998: 
                   1999:   ENHANCEMENTS:
                   2000: 
                   2001:     - Made the "max verbosity" setting in the rsyncd.conf file settable on a
                   2002:       per-module basis (which now matches the documentation).
                   2003: 
                   2004:     - The support/rrsync script has been upgraded to verify the args of options
                   2005:       that take args (instead of rejecting any such options).  The script was
                   2006:       also changed to try to be more secure and to fix a problem in the parsing
                   2007:       of a pull operation that has multiple sources.
                   2008: 
                   2009:     - Improved the documentation that explains the difference between a
                   2010:       normal daemon transfer and a daemon-over remote-shell transfer.
                   2011: 
                   2012:     - Some of the diffs supplied in the patches dir were fixed and/or
                   2013:       improved.
                   2014: 
                   2015:   BUILD CHANGES:
                   2016: 
                   2017:     - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
                   2018:       NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
                   2019:       find in the /etc/group file).
                   2020: 
                   2021:     - Added a test to the test suite, itemized.test, that tests the output of
                   2022:       -i (log-format w/%i) and some double-verbose messages.

                   2026: Protocol: 29 (unchanged)
                   2027: Changes since 2.6.4:
                   2028: 
                   2029:   OUTPUT CHANGES:
                   2030: 
                   2031:     - Non-printable chars in filenames are now output using backslash-
                   2032:       escaped characters rather than '?'s.  Any non-printable character is
                   2033:       output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
                   2034:       is now output as "\\".  Rsync also uses your locale setting, which
                   2035:       can make it treat fewer high-bit characters as non-printable.
                   2036: 
                   2037:     - If rsync received an empty file-list when pulling files, it would
                   2038:       output a "nothing to do" message and exit with a 0 (success) exit
                   2039:       status, even if the remote rsync returned an error (it did not do
                   2040:       this under the same conditions when pushing files).  This was changed
                   2041:       to make the pulling behavior the same as the pushing behavior:  we
                   2042:       now do the normal end-of-run outputting (depending on options) and
                   2043:       exit with the appropriate exit status.
                   2044: 
                   2045:   BUG FIXES:
                   2046: 
                   2047:     - A crash bug was fixed when a daemon had its "path" set to "/", did
                   2048:       not have chroot enabled, and used some anchored excludes in the
                   2049:       rsyncd.conf file.
                   2050: 
                   2051:     - Fixed a bug in the transfer of a single file when -H is specified
                   2052:       (rsync would either infinite loop or perhaps crash).
                   2053: 
                   2054:     - Fixed a case where the generator might try (and fail) to tweak the
                   2055:       write-permissions of a read-only directory in list-only mode (this
                   2056:       only caused an annoying warning message).
                   2057: 
                   2058:     - If --compare-dest or --link-dest uses a locally-copied file as the
                   2059:       basis for an updated version, log this better when --verbose or -i
                   2060:       is in effect.
                   2061: 
                   2062:     - Fixed the accidental disabling of --backup during the --delete-after
                   2063:       processing.
                   2064: 
                   2065:     - Restored the ability to use the --address option in client mode (in
                   2066:       addition to its use in daemon mode).
                   2067: 
                   2068:     - Make sure that some temporary progress information from the delete
                   2069:       processing does not get left on the screen when it is followed by a
                   2070:       newline.
                   2071: 
                   2072:     - When --existing skips a directory with extra verbosity, refer to it
                   2073:       as a "directory", not a "file".
                   2074: 
                   2075:     - When transferring a single file to a different-named file, any
                   2076:       generator messages that are source-file related no longer refer to
                   2077:       the file by the destination filename.
                   2078: 
                   2079:     - Fixed a bug where hard-linking a group of files might fail if the
                   2080:       generator hasn't created a needed destination directory yet.
                   2081: 
                   2082:     - Fixed a bug where a hard-linked group of files that is newly-linked
                   2083:       to a file in a --link-dest dir doesn't link the files from the rest
                   2084:       of the cluster.
                   2085: 
                   2086:     - When deleting files with the --one-file-system (-x) option set, rsync
                   2087:       no longer tries to remove files from inside a mount-point on the
                   2088:       receiving side.  Also, we don't complain about being unable to remove
                   2089:       the mount-point dir.
                   2090: 
                   2091:     - Fixed a compatibility problem when using --cvs-ignore (-C) and
                   2092:       sending files to an older rsync without using --delete.
                   2093: 
                   2094:     - Make sure that a "- !" or "+ !" include/exclude pattern does not
                   2095:       trigger the list-clearing action that is reserved for "!".
                   2096: 
                   2097:     - Avoid a timeout in the generator when the sender/receiver aren't
                   2098:       handling the generator's checksum output quickly enough.
                   2099: 
                   2100:     - Fixed the omission of some directories in the delete processing when
                   2101:       --relative (-R) was combined with a source path that had a trailing
                   2102:       slash.
                   2103: 
                   2104:     - Fixed a case where rsync would erroneously delete some files and then
                   2105:       re-transfer them when the options --relative (-R) and --recursive
                   2106:       (-r) were both enabled (along with --delete) and a source path had a
                   2107:       trailing slash.
                   2108: 
                   2109:     - Make sure that --max-size doesn't affect a device or a symlink.
                   2110: 
                   2111:     - Make sure that a system with a really small MAXPATHLEN does not cause
                   2112:       the buffers in readfd_unbuffered() to be too small to receive normal
                   2113:       messages.  (This mainly affected Cygwin.)
                   2114: 
                   2115:     - If a source pathname ends with a filename of "..", treat it as if
                   2116:       "../" had been specified (so that we don't copy files to the parent
                   2117:       dir of the destination).
                   2118: 
                   2119:     - If --delete is combined with a file-listing rsync command (i.e. no
                   2120:       transfer is happening), avoid outputting a warning that we couldn't
                   2121:       delete anything.
                   2122: 
                   2123:     - If --stats is specified with --delete-after, ensure that all the
                   2124:       "deleting" messages are output before the statistics.
                   2125: 
                   2126:     - Improved one "if" in the deletion code that was only checking errno
                   2127:       for ENOTEMPTY when it should have also been checking for EEXIST (for
                   2128:       compatibility with OS variations).
                   2129: 
                   2130:   ENHANCEMENTS:
                   2131: 
                   2132:     - Added the --only-write-batch=FILE option that may be used (instead
                   2133:       of --write-batch=FILE) to create a batch file without doing any
                   2134:       actual updating of the destination.  This allows you to divert all
                   2135:       the file-updating data away from a slow data link (as long as you
                   2136:       are pushing the data to the remote server when creating the batch).
                   2137: 
                   2138:     - When the generator is taking a long time to fill up its output buffer
                   2139:       (e.g. if the transferred files are few, small, or missing), it now
                   2140:       periodically flushes the output buffer so that the sender/receiver
                   2141:       can get started on the files sooner rather than later.
                   2142: 
                   2143:     - Improved the keep-alive code to handle a long silence between the
                   2144:       sender and the receiver that can occur when the sender is receiving
                   2145:       the checksum data for a large file.
                   2146: 
                   2147:     - Improved the auth-errors that are logged by the daemon to include
                   2148:       some information on why the authorization failed:  wrong user,
                   2149:       password mismatch, etc.  (The client-visible message is unchanged!)
                   2150: 
                   2151:     - Improved the client's handling of an "@ERROR" from a daemon so that
                   2152:       it does not complain about an unexpectedly closed socket (since we
                   2153:       really did expect the socket to close).
                   2154: 
                   2155:     - If the daemon can't open the log-file specified in rsyncd.conf, fall
                   2156:       back to using syslog and log an appropriate warning.  This is better
                   2157:       than what was typically a totally silent (and fatal) failure (since a
                   2158:       daemon is not usually run with the --no-detach option that was
                   2159:       necessary to see the error on stderr).
                   2160: 
                   2161:     - The man pages now consistently refer to an rsync daemon as a "daemon"
                   2162:       instead of a "server" (to distinguish it from the server process in a
                   2163:       non-daemon transfer).
                   2164: 
                   2165:     - Made a small change to the rrsync script (restricted rsync -- in the
                   2166:       support dir) to make a read-only server reject all --remove-* options
                   2167:       when sending files (to future-proof it against the possibility of
                   2168:       other similar options being added at some point).
                   2169: 
                   2170:   INTERNAL:
                   2171: 
                   2172:     - Rsync now calls setlocale(LC_CTYPE, "").  This enables isprint() to
                   2173:       better discern which filename characters need to be escaped in
                   2174:       messages (which should result in fewer escaped characters in some
                   2175:       locales).
                   2176: 
                   2177:     - Improved the naming of the log-file open/reopen/close functions.
                   2178: 
                   2179:     - Removed some protocol-compatibility code that was only needed to help
                   2180:       someone running a pre-release of 2.6.4.
                   2181: 
                   2182:   BUILD CHANGES:
                   2183: 
                   2184:     - Added configure option "--disable-locale" to disable any use of
                   2185:       setlocale() in the binary.
                   2186: 
                   2187:     - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
                   2188:       rsync from being built without symlink or hard-link support.
                   2189: 
                   2190:     - Only #define HAVE_REMSH if it is going to be set to 1.
                   2191: 
                   2192:     - Configure now disables the use of mkstemp() under HP-UX (since they
                   2193:       refuse to fix its broken handling of large files).
                   2194: 
                   2195:     - Configure now explicitly checks for the lseek64() function so that
                   2196:       the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
                   2197:       presence based on the presence of the off64_t type.
                   2198: 
                   2199:     - Configure no longer mentions the change in the default remote-shell
                   2200:       (from rsh to ssh) that occurred for the 2.6.0 release.
                   2201: 
                   2202:     - Some minor enhancements to the test scripts.
                   2203: 
                   2204:     - Added a few new *.diff files to the patches dir, including a patch
                   2205:       that enables the optional copying of extended attributes.
                   2206: 
                   2207: 
                   2208: NEWS for rsync 2.6.4 (30 March 2005)
                   2209: Protocol: 29 (changed)
                   2210: Changes since 2.6.3:
                   2211: 
                   2212:   OUTPUT CHANGES:
                   2213: 
                   2214:     - When rsync deletes a directory and outputs a verbose message about
                   2215:       it, it now appends a trailing slash to the name instead of (only
                   2216:       sometimes) outputting a preceding "directory " string.
                   2217: 
                   2218:     - The --stats output will contain file-list time-statistics if both
                   2219:       sides are 2.6.4, or if the local side is 2.6.4 and the files are
                   2220:       being pushed (since the stats come from the sending side).
                   2221:       (Requires protocol 29 for a pull.)
                   2222: 
                   2223:     - The "%o" (operation) log-format escape now has a third value (besides
                   2224:       "send" and "recv"):  "del." (with trailing dot to make it 4 chars).
                   2225:       This changes the way deletions are logged in the daemon's log file.
                   2226: 
                   2227:     - When the --log-format option is combined with --verbose, rsync now
                   2228:       avoids outputting the name of the file twice in most circumstances.
                   2229:       As long as the --log-format item does not refer to any post-transfer
                   2230:       items (such as %b or %c), the --log-format message is output prior to
                   2231:       the transfer, so --verbose is now the equivalent of a --log-format of
                   2232:       '%n%L' (which outputs the name and any link info).  If the log output
                   2233:       must occur after the transfer to be complete, the only time the name
                   2234:       is also output prior to the transfer is when --progress was specified
                   2235:       (so that the name will precede the progress stats, and the full
                   2236:       --log-format output will come after).
                   2237: 
                   2238:     - Non-printable characters in filenames are replaced with a '?' to
                   2239:       avoid corrupting the screen or generating empty lines in the output.
                   2240:   
                   2241:   BUG FIXES:
                   2242: 
                   2243:     - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
                   2244:       was only treating it as a special token in an rsync include/exclude
                   2245:       file).
                   2246: 
                   2247:     - The combination of --verbose and --dry-run now mentions the full list
                   2248:       of changes that would be output without --dry-run.
                   2249: 
                   2250:     - Avoid a mkdir warning when removing a directory in the destination
                   2251:       that already exists in the --backup-dir.
                   2252: 
                   2253:     - An OS that has a binary mode for its files (such as cygwin) needed
                   2254:       setmode(fd, O_BINARY) called on the temp-file we opened with
                   2255:       mkstemp().  (Fix derived from cygwin's 2.6.3 rsync package.)
                   2256: 
                   2257:     - Fixed a potential hang when verbosity is high, the client side is
                   2258:       the sender, and the file-list is large.
                   2259: 
                   2260:     - Fixed a potential protocol-corrupting bug where the generator could
                   2261:       merge a message from the receiver into the middle of a multiplexed
                   2262:       packet of data if only part of that data had been written out to the
                   2263:       socket when the message from the generator arrived.
                   2264: 
                   2265:     - We now check if the OS doesn't support using mknod() for creating
                   2266:       FIFOs and sockets, and compile-in some compatibility code using
                   2267:       mkfifo() and socket() when necessary.
                   2268: 
                   2269:     - Fixed an off-by-one error in the handling of --max-delete=N.  Also,
                   2270:       if the --max-delete limit is exceeded during a run, we now output a
                   2271:       warning about this at the end of the run and exit with a new error
                   2272:       code (25).
                   2273: 
                   2274:     - One place in the code wasn't checking if fork() failed.
                   2275: 
                   2276:     - The "ignore nonreadable" daemon parameter used to erroneously affect
                   2277:       readable symlinks that pointed to a non-existent file.
                   2278: 
                   2279:     - If the OS does not have lchown() and a chown() of a symlink will
                   2280:       affect the referent of a symlink (as it should), we no longer try
                   2281:       to set the user and group of a symlink.
                   2282: 
                   2283:     - The generator now properly runs the hard-link loop and the dir-time
                   2284:       rewriting loop after we're sure that the redo phase is complete.
                   2285: 
                   2286:     - When --backup was specified with --partial-dir=DIR, where DIR is a
                   2287:       relative path, the backup code was erroneously trying to backup a
                   2288:       file that was put into the partial-dir.
                   2289: 
                   2290:     - If a file gets resent in a single transfer and the --backup option is
                   2291:       enabled along with --inplace, rsync no longer performs a duplicate
                   2292:       backup (it used to overwrite the first backup with the failed file).
                   2293: 
                   2294:     - One call to flush_write_file() was not being checked for an error.
                   2295: 
                   2296:     - The --no-relative option was not being sent from the client to a
                   2297:       server sender.
                   2298: 
                   2299:     - If an rsync daemon specified "dont compress = ..." for a file and the
                   2300:       client tried to specify --compress, the libz code was not handling a
                   2301:       compression level of 0 properly.  This could cause a transfer failure
                   2302:       if the block-size for a file was large enough (e.g. rsync might have
                   2303:       exited with an error for large files).
                   2304: 
                   2305:     - Fixed a bug that would sometimes surface when using --compress and
                   2306:       sending a file with a block-size larger than 64K (either manually
                   2307:       specified, or computed due to the file being really large).  Prior
                   2308:       versions of rsync would sometimes fail to decompress the data
                   2309:       properly, and thus the transferred file would fail its verification.
                   2310: 
                   2311:     - If a daemon can't open the specified log file (i.e. syslog is not
                   2312:       being used), die without crashing.  We also output an error about
                   2313:       the failure on stderr (which will only be seen if --no-detach was
                   2314:       specified) and exit with a new error code (6).
                   2315: 
                   2316:     - A local transfer no longer duplicates all its include/exclude options
                   2317:       (since the forked process already has a copy of the exclude list,
                   2318:       there's no need to send them a set of duplicates).
                   2319: 
                   2320:     - The output of the items that are being updated by the generator (dirs,
                   2321:       symlinks, devices) is now intermingled in the proper order with the
                   2322:       output from the items that the receiver is updating (regular files)
                   2323:       when pulling.  This misordering was particularly bad when --progress
                   2324:       was specified.  (Requires protocol 29.)
                   2325: 
                   2326:     - When --timeout is specified, lulls that occur in the transfer while
                   2327:       the generator is doing work that does not generate socket traffic
                   2328:       (looking for changed files, deleting files, doing directory-time
                   2329:       touch-ups, etc.) will cause a new keep-alive packet to be sent that
                   2330:       should keep the transfer going as long as the generator continues to
                   2331:       make progress.  (Requires protocol 29.)
                   2332: 
                   2333:     - The stat size of a device is not added to the total file size of the
                   2334:       items in the transfer (the size might be undefined on some OSes).
                   2335: 
                   2336:     - Fixed a problem with refused-option messages sometimes not making it
                   2337:       back to the client side when a remote --files-from was in effect and
                   2338:       the daemon was the receiver.
                   2339: 
                   2340:     - The --compare-dest option was not updating a file that differed in
                   2341:       (the preserved) attributes from the version in the compare-dest DIR.
                   2342: 
                   2343:     - When rsync is copying files into a write-protected directory, fixed
                   2344:       the change-report output for the directory so that we don't report
                   2345:       an identical directory as changed.
                   2346: 
                   2347:   ENHANCEMENTS:
                   2348: 
                   2349:     - Rsync now supports popt's option aliases, which means that you can
                   2350:       use /etc/popt and/or ~/.popt to create your own option aliases.
                   2351: 
                   2352:     - Added the --delete-during (--del) option which will delete files
                   2353:       from the receiving side incrementally as each directory in the
                   2354:       transfer is being processed.  This makes it more efficient than the
                   2355:       default, before-the-transfer behavior, which is now also available as
                   2356:       --delete-before (and is still the default --delete-WHEN option that
                   2357:       will be chosen if --delete or --delete-excluded is specified without
                   2358:       a --delete-WHEN choice).  All the --del* options infer --delete, so
                   2359:       an rsync daemon that refuses "delete" will still refuse to allow any
                   2360:       file-deleting options (including the new --remove-sent-files option).
                   2361: 
                   2362:     - All the --delete-WHEN options are now more memory efficient:
                   2363:       Previously an duplicate set of file-list objects was created on the
                   2364:       receiving side for the entire destination hierarchy.  The new
                   2365:       algorithm only creates one directory of objects at a time (for files
                   2366:       inside the transfer).
                   2367: 
                   2368:     - Added the --copy-dest option, which works like --link-dest except
                   2369:       that it locally copies identical files instead of hard-linking them.
                   2370: 
                   2371:     - Added support for specifying multiple --compare-dest, --copy-dest, or
                   2372:       --link-dest options, but only of a single type. (Promoted from the
                   2373:       patches dir and enhanced.) (Requires protocol 29.)
                   2374: 
                   2375:     - Added the --max-size option. (Promoted from the patches dir.)
                   2376: 
                   2377:     - The daemon-mode options are now separated from the normal rsync
                   2378:       options so that they can't be mixed together.  This makes it
                   2379:       impossible to start a daemon that has improper default option values
                   2380:       (which could cause problems when a client connects, such as hanging
                   2381:       or crashing).
                   2382: 
                   2383:     - The --bwlimit option may now be used in combination with --daemon
                   2384:       to specify both a default value for the daemon side and a value
                   2385:       that cannot be exceeded by a user-specified --bwlimit option.
                   2386: 
                   2387:     - Added the "port" parameter to the rsyncd.conf file. (Promoted from
                   2388:       the patches dir.)  Also added "address".  The command-line options
                   2389:       take precedence over a config-file option, as expected.
                   2390: 
                   2391:     - In _exit_cleanup(): when we are exiting with a partially-received
                   2392:       file, we now flush any data in the write-cache before closing the
                   2393:       partial file.
                   2394: 
                   2395:     - The --inplace support was enhanced to work with --compare-dest,
                   2396:       --link-dest, and (the new) --copy-dest options. (Requires protocol
                   2397:       29.)
                   2398: 
                   2399:     - Added the --dirs (-d) option for an easier way to copy directories
                   2400:       without recursion.  Any directories that are encountered are created
                   2401:       on the destination.  Specifying a directory with a trailing slash
                   2402:       copies its immediate contents to the destination.
                   2403: 
                   2404:     - The --files-from option now implies --dirs (-d).
                   2405: 
                   2406:     - Added the --list-only option, which is mainly a way for the client to
                   2407:       put the server into listing mode without needing to resort to any
                   2408:       internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
                   2409:       for a non-recursive listing).  This option is used automatically
                   2410:       (behind the scenes) when a modern rsync speaks to a modern daemon,
                   2411:       but may also be specified manually if you want to force the use of
                   2412:       the --list-only option over a remote-shell connection.
                   2413: 
                   2414:     - Added the --omit-dir-times (-O) option, which will avoid updating
                   2415:       the modified time for directories when --times was specified.  This
                   2416:       option will avoid an extra pass through the file-list at the end of
                   2417:       the transfer (to tweak all the directory times), which may provide
                   2418:       an appreciable speedup for a really large transfer. (Promoted from
                   2419:       the patches dir.)
                   2420: 
                   2421:     - Added the --filter (-f) option and its helper option, -F.  Filter
                   2422:       rules are an extension to the existing include/exclude handling
                   2423:       that also supports nested filter files as well as per-directory
                   2424:       filter files (like .cvsignore, but with full filter-rule parsing).
                   2425:       This new option was chosen in order to ensure that all existing
                   2426:       include/exclude processing remained 100% compatible with older
                   2427:       versions.  Protocol 29 is needed for full filter-rule support, but
                   2428:       backward-compatible rules work with earlier protocol versions.
                   2429:       (Promoted from the patches dir and enhanced.)
                   2430: 
                   2431:     - Added the --delay-updates option that puts all updated files into
                   2432:       a temporary directory (by default ".~tmp~", but settable via the
                   2433:       --partial-dir=DIR option) until the end of the transfer.  This
                   2434:       makes the updates a little more atomic for a large transfer.
                   2435: 
                   2436:     - If rsync is put into the background, any output from --progress is
                   2437:       reduced.
                   2438: 
                   2439:     - Documented the "max verbosity" setting for rsyncd.conf.  (This
                   2440:       setting was added a couple releases ago, but left undocumented.)
                   2441: 
                   2442:     - The sender and the generator now double-check the file-list index
                   2443:       they are given, and refuse to try to do a file transfer on a
                   2444:       non-file index (since that would indicate that something had gone
                   2445:       very wrong).
                   2446: 
                   2447:     - Added the --itemize-changes (-i) option, which is a way to output a
                   2448:       more detailed list of what files changed and in what way.  The effect
                   2449:       is the same as specifying a --log-format of "%i %n%L" (see both the
                   2450:       rsync and rsyncd.conf manpages).  Works with --dry-run too.
                   2451: 
                   2452:     - Added the --fuzzy (-y) option, which attempts to find a basis file
                   2453:       for a file that is being created from scratch.  The current algorithm
                   2454:       only looks in the destination directory for the created file, but it
                   2455:       does attempt to find a match based on size/mod-time (in case the file
                   2456:       was renamed with no other changes) as well as based on a fuzzy
                   2457:       name-matching algorithm.  This option requires protocol 29 because it
                   2458:       needs the new file-sorting order.  (Promoted from patches dir and
                   2459:       enhanced.) (Requires protocol 29.)
                   2460: 
                   2461:     - Added the --remove-sent-files option, which lets you move files
                   2462:       between systems.
                   2463: 
                   2464:     - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
                   2465:       enclosed in '[' and ']' (e.g. "[::1]").  (We already allowed IPv6
                   2466:       literals in the rsync://HOST:PORT/PATH format.)
                   2467: 
                   2468:     - When rsync recurses to build the file list, it no longer keeps open
                   2469:       one or more directory handles from the dir's parent dirs.
                   2470: 
                   2471:     - When building under windows, the default for --daemon is now to
                   2472:       avoid detaching, requiring the new --detach option to force rsync
                   2473:       to detach.
                   2474: 
                   2475:     - The --dry-run option can now be combined with either --write-batch or
                   2476:       --read-batch, allowing you to run a do-nothing test command to see
                   2477:       what would happen without --dry-run.
                   2478: 
                   2479:     - The daemon's "read only" config item now sets an internal read_only
                   2480:       variable that makes extra sure that no write/delete calls on the
                   2481:       read-only side can succeed.
                   2482: 
                   2483:     - The log-format % escapes can now have a numeric field width in
                   2484:       between the % and the escape letter (e.g. "%-40n %08p").
                   2485: 
                   2486:     - Improved the option descriptions in the --help text.
                   2487: 
                   2488:   SUPPORT FILES:
                   2489: 
                   2490:     - Added atomic-rsync to the support dir: a perl script that will
                   2491:       transfer some files using rsync, and then move the updated files into
                   2492:       place all at once at the end of the transfer.  Only works when
                   2493:       pulling, and uses --link-dest and a parallel hierarchy of files to
                   2494:       effect its update.
                   2495: 
                   2496:     - Added mnt-excl to the support dir: a perl script that takes the
                   2497:       /proc/mounts file and translates it into a set of excludes that will
                   2498:       exclude all mount points (even mapped mounts to the same disk).  The
                   2499:       excludes are made relative to the specified source dir and properly
                   2500:       anchored.
                   2501: 
                   2502:     - Added savetransfer.c to the support dir: a C program that can make
                   2503:       a copy of all the data that flows over the wire.  This lets you test
                   2504:       for data corruption (by saving the data on both the sending side and
                   2505:       the receiving side) and provides one way to debug a protocol error.
                   2506: 
                   2507:     - Added rrsync to the support dir: this is an updated version of Joe
                   2508:       Smith's restricted rsync perl script.  This helps to ensure that only
                   2509:       certain rsync commands can be run by an ssh invocation.
                   2510: 
                   2511:   INTERNAL:
                   2512: 
                   2513:     - Added better checking of the checksum-header values that come over
                   2514:       the socket.
                   2515: 
                   2516:     - Merged a variety of file-deleting functions into a single function so
                   2517:       that it is easier to maintain.
                   2518: 
                   2519:     - Improved the type of some variables (particularly blocksize vars) for
                   2520:       consistency and proper size.
                   2521: 
                   2522:     - Got rid of the uint64 type (which we didn't need).
                   2523: 
                   2524:     - Use a slightly more compatible set of core #include directives.
                   2525: 
                   2526:     - Defined int32 in a way that ensures that the build dies if we can't
                   2527:       find a variable with at least 32 bits.
                   2528: 
                   2529:   PROTOCOL DIFFERENCES FOR VERSION 29:
                   2530: 
                   2531:     - A 16-bit flag-word is transmitted after every file-list index.  This
                   2532:       indicates what is changing between the sender and the receiver.  The
                   2533:       generator now transmits an index and a flag-word to indicate when
                   2534:       dirs and symlinks have changed (instead of producing a message),
                   2535:       which makes the outputting of the information more consistent and
                   2536:       less prone to screen corruption (because the local receiver/sender is
                   2537:       now outputting all the file-change info messages).
                   2538: 
                   2539:     - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
                   2540:       in the flag-word and the name of the file that was linked immediately
                   2541:       follows in vstring format (see below).
                   2542: 
                   2543:     - If a file is being transferred with an alternate-basis file, the
                   2544:       ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
                   2545:       byte follows, indicating what type of basis file was chosen.  If that
                   2546:       indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
                   2547:       is set in the flag-word and the name of the match in vstring format
                   2548:       follows the basis byte.  A vstring is a variable length string that
                   2549:       has its size written prior to the string, and no terminating null.
                   2550:       If the string is from 1-127 bytes, the length is a single byte.  If
                   2551:       it is from 128-32767 bytes, the length is written as ((len >> 8) |
                   2552:       0x80) followed by (len % 0x100).
                   2553: 
                   2554:     - The sending of exclude names is done using filter-rule syntax.  This
                   2555:       means that all names have a prefixed rule indicator, even excludes
                   2556:       (which used to be sent as a bare pattern, when possible).  The -C
                   2557:       option will include the per-dir .cvsignore merge file in the list of
                   2558:       filter rules so it is positioned correctly (unlike in some older
                   2559:       transfer scenarios).
                   2560: 
                   2561:     - Rsync sorts the filename list in a different way: it sorts the subdir
                   2562:       names after the non-subdir names for each dir's contents, and it
                   2563:       always puts a dir's contents immediately after the dir's name in the
                   2564:       list.  (Previously an item named "foo.txt" would sort in between
                   2565:       directory "foo/" and "foo/bar".)
                   2566: 
                   2567:     - When talking to a protocol 29 rsync daemon, a list-only request
                   2568:       is able to note this before the options are sent over the wire and
                   2569:       the new --list-only option is included in the options.
                   2570: 
                   2571:     - When the --stats bytes are sent over the wire (or stored in a batch),
                   2572:       they now include two elapsed-time values: one for how long it took to
                   2573:       build the file-list, and one for how long it took to send it over the
                   2574:       wire (each expressed in thousandths of a second).
                   2575: 
                   2576:     - When --delete-excluded is specified with some filter rules (AKA
                   2577:       excludes), a client sender will now initiate a send of the rules to
                   2578:       the receiver (older protocols used to omit the sending of excludes in
                   2579:       this situation since there were no receiver-specific rules that
                   2580:       survived --delete-excluded back then).  Note that, as with all the
                   2581:       filter-list sending, only items that are significant to the other
                   2582:       side will actually be sent over the wire, so the filter-rule list
                   2583:       that is sent in this scenario is often empty.
                   2584: 
                   2585:     - An index equal to the file-list count is sent as a keep-alive packet
                   2586:       from the generator to the sender, which then forwards it on to the
                   2587:       receiver.  This normally invalid index is only a valid keep-alive
                   2588:       packet if the 16-bit flag-word that follows it contains a single bit
                   2589:       (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
                   2590: 
                   2591:     - A protocol-29 batch file includes a bit for the setting of the --dirs
                   2592:       option and for the setting of the --compress option.  Also, the shell
                   2593:       script created by --write-batch will use the --filter option instead
                   2594:       of --exclude-from to capture any filter rules.
                   2595: 
                   2596:   BUILD CHANGES:
                   2597: 
                   2598:     - Handle an operating system that use mkdev() in place of makedev().
                   2599: 
                   2600:     - Improved configure to better handle cross-compiling.
                   2601: 
                   2602: 
                   2603: NEWS for rsync 2.6.3 (30 Sep 2004)
                   2604: Protocol: 28 (unchanged)
                   2605: Changes since 2.6.2:
                   2606: 
                   2607:   SECURITY FIXES:
                   2608: 
                   2609:     - A bug in the sanitize_path routine (which affects a non-chrooted
                   2610:       rsync daemon) could allow a user to craft a pathname that would get
                   2611:       transformed into an absolute path for certain options (but not for
                   2612:       file-transfer names).  If you're running an rsync daemon with chroot
                   2613:       disabled, *please upgrade*, ESPECIALLY if the user privs you run
                   2614:       rsync under is anything above "nobody".
                   2615: 
                   2616:   OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
                   2617: 
                   2618:     - Please note that the 2-line footer (output when verbose) now uses the
                   2619:       term "sent" instead of "wrote" and "received" instead of "read".  If
                   2620:       you are not parsing the numeric values out of this footer, a script
                   2621:       would be better off using the empty line prior to the footer as the
                   2622:       indicator that the verbose output is over.
                   2623:       
                   2624:     - The output from the --stats option was similarly affected to change
                   2625:       "written" to "sent" and "read" to "received".
                   2626: 
                   2627:     - Rsync ensures that a filename that contains a newline gets mentioned
                   2628:       with each newline transformed into a question mark (which prevents a
                   2629:       filename from causing an empty line to be output).
                   2630: 
                   2631:     - The "backed up ..." message that is output when at least 2 --verbose
                   2632:       options are specified is now the same both with and without the
                   2633:       --backup-dir option.
                   2634: 
                   2635:   BUG FIXES:
                   2636: 
                   2637:     - Fixed a crash bug that might appear when --delete was used and
                   2638:       multiple source directories were specified.
                   2639: 
                   2640:     - Fixed a 32-bit truncation of the file length when generating the
                   2641:       checksums.
                   2642: 
                   2643:     - The --backup code no longer attempts to create some directories
                   2644:       over and over again (generating warnings along the way).
                   2645: 
                   2646:     - Fixed a bug in the reading of the secrets file (by the daemon) and
                   2647:       the password file (by the client):  the files no longer need to be
                   2648:       terminated by a newline for their content to be read in.
                   2649: 
                   2650:     - If a file has a read error on the sending side or the reconstructed
                   2651:       data doesn't match the expected checksum (perhaps due to the basis
                   2652:       file changing during the transfer), the receiver will no longer
                   2653:       retain the resulting file unless the --partial option was specified.
                   2654:       (Note: for the read-error detection to work, neither side can be
                   2655:       older than 2.6.3 -- older receivers will always retain the file, and
                   2656:       older senders don't tell the receiver that the file had a read
                   2657:       error.)
                   2658: 
                   2659:     - If a file gets resent in a single transfer and the --backup option
                   2660:       is enabled, rsync no longer performs a duplicate backup (it used to
                   2661:       overwrite the original file in the backup area).
                   2662: 
                   2663:     - Files specified in the daemon's "exclude" or "exclude from" config
                   2664:       items are now excluded from being uploaded (assuming that the module
                   2665:       allows uploading at all) in addition to the old download exclusion.
                   2666: 
                   2667:     - Got rid of a potential hang in the receiver when near the end of a
                   2668:       phase.
                   2669: 
                   2670:     - When using --backup without a --backup-dir, rsync no longer preserves
                   2671:       the modify time on directories.  This avoids confusing NFS.
                   2672: 
                   2673:     - When --copy-links (-L) is specified, we now output a separate error
                   2674:       for a symlink that has no referent instead of claiming that a file
                   2675:       "vanished".
                   2676: 
                   2677:     - The --copy-links (-L) option no longer has the side-effect of telling
                   2678:       the receiving side to follow symlinks.  See the --keep-dirlinks
                   2679:       option (mentioned below) for a way to specify that behavior.
                   2680: 
                   2681:     - Error messages from the daemon server's option-parsing (such as
                   2682:       refused options) are now successfully transferred back to the client
                   2683:       (the server used to fail to send the message because the socket
                   2684:       wasn't in the right state for the message to get through).
                   2685: 
                   2686:     - Most transfer errors that occur during a daemon transfer are now
                   2687:       returned to the user in addition to being logged (some messages are
                   2688:       intended to be daemon-only and are not affected by this).
                   2689: 
                   2690:     - Fixed a bug in the daemon authentication code when using one of the
                   2691:       batch-processing options.
                   2692: 
                   2693:     - We try to work around some buggy IPv6 implementations that fail to
                   2694:       implement IPV6_V6ONLY.  This should fix the "address in use" error
                   2695:       that some daemons get when running on an OS with a buggy IPv6
                   2696:       implementation.  Also, if the new code gets this error, we might
                   2697:       suggest that the user specify --ipv4 or --ipv6 (if we think it will
                   2698:       help).
                   2699: 
                   2700:     - When the remote rsync dies, make a better effort to recover any error
                   2701:       messages it may have sent before dying (the local rsync used to just
                   2702:       die with a socket-write error).
                   2703: 
                   2704:     - When using --delete and a --backup-dir that contains files that are
                   2705:       hard-linked to their destination equivalents, rsync now makes sure
                   2706:       that removed files really get removed (avoids a really weird rename()
                   2707:       behavior).
                   2708: 
                   2709:     - Avoid a bogus run-time complaint about a lack of 64-bit integers when
                   2710:       the int64 type is defined as an off_t and it actually has 64-bits.
                   2711: 
                   2712:     - Added a configure check for open64() without mkstemp64() so that we
                   2713:       can avoid using mkstemp() when such a combination is encountered.
                   2714:       This bypasses a problem writing out large temp files on OSes such as
                   2715:       AIX and HP-UX.
                   2716: 
                   2717:     - Fixed an age-old crash problem with --read-batch on a local copy
                   2718:       (rsync was improperly assuming --whole-file for the local copy).
                   2719: 
                   2720:     - When --dry-run (-n) is used and the destination directory does not
                   2721:       exist, rsync now produces a correct report of files that would be
                   2722:       sent instead of dying with a chdir() error.
                   2723: 
                   2724:     - Fixed a bug that could cause a slow-to-connect rsync daemon to die
                   2725:       with an error instead of waiting for the connection to finish.
                   2726: 
                   2727:     - Fixed an ssh interaction that could cause output to be lost when the
                   2728:       user chose to combine the output of rsync's stdout and stderr (e.g.
                   2729:       using the "2>&1").
                   2730: 
                   2731:     - Fixed an option-parsing bug when --files-from got passed to a daemon.
                   2732: 
                   2733:   ENHANCEMENTS:
                   2734: 
                   2735:     - Added the --partial-dir=DIR option that lets you specify where to
                   2736:       (temporarily) put a partially transferred file (instead of over-
                   2737:       writing the destination file).  E.g.  --partial-dir=.rsync-partial
                   2738:       Also added support for the RSYNC_PARTIAL_DIR environment variable
                   2739:       that, when found, transforms a regular --partial option (such as
                   2740:       the convenient -P option) into one that also specifies a directory.
                   2741: 
                   2742:     - Added --keep-dirlinks (-K), which allows you to symlink a directory
                   2743:       onto another partition on the receiving side and have rsync treat it
                   2744:       as matching a normal directory from the sender.
                   2745: 
                   2746:     - Added the --inplace option that tells rsync to write each destination
                   2747:       file without using a temporary file.  The matching of existing data
                   2748:       in the destination file can be severely limited by this, but there
                   2749:       are also cases where this is more efficient (such as appending data).
                   2750:       Use only when needed (see the man page for more details).
                   2751: 
                   2752:     - Added the "write only" option for the daemon's config file.
                   2753: 
                   2754:     - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
                   2755:       and documented all these options in the man page.
                   2756: 
                   2757:     - Improved the handling of the --bwlimit option so that it's less
                   2758:       bursty, more accurate, and works properly over a larger range of
                   2759:       values.
                   2760: 
                   2761:     - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
                   2762:       SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
                   2763: 
                   2764:     - Added the --checksum-seed=N option for advanced users.
                   2765: 
                   2766:     - Batch writing/reading has a brand-new implementation that is simpler,
                   2767:       fixes a few weird problems with the old code (such as no longer
                   2768:       sprinkling the batch files into different dirs or even onto different
                   2769:       systems), and is much less intrusive into the code (making it easier
                   2770:       to maintain for the future).  The new code generates just one data
                   2771:       file instead of three, which makes it possible to read the batch on
                   2772:       stdin via a remote shell.  Also, the old requirement of forcing the
                   2773:       same fixed checksum-seed for all batch processing has been removed.
                   2774: 
                   2775:     - If an rsync daemon has a module set with "list = no" (which hides its
                   2776:       presence in the list of available modules), a user that fails to
                   2777:       authenticate gets the same "unknown module" error that they would get
                   2778:       if the module were actually unknown (while still logging the real
                   2779:       error to the daemon's log file).  This prevents fishing for module
                   2780:       names.
                   2781: 
                   2782:     - The daemon's "refuse options" config item now allows you to match
                   2783:       option names using wildcards and/or the single-letter option names.
                   2784: 
                   2785:     - Each transferred file now gets its permissions and modified-time
                   2786:       updated before the temp-file gets moved into place.  Previously, the
                   2787:       finished file would have a very brief window where its permissions
                   2788:       disallowed all group and world access.
                   2789: 
                   2790:     - Added the ability to parse a literal IPv6 address in an "rsync:" URL
                   2791:       (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
                   2792: 
                   2793:     - The daemon's wildcard expanding code can now handle more than 1000
                   2794:       filenames (it's now limited by memory instead of having a hard-wired
                   2795:       limit).
                   2796: 
                   2797:   INTERNAL:
                   2798: 
                   2799:     - Some cleanup in the exclude code has saved some per-exclude memory
                   2800:       and made the code easier to maintain.
                   2801: 
                   2802:     - Improved the argv-overflow checking for a remote command that has a
                   2803:       lot of args.
                   2804: 
                   2805:     - Use rsyserr() in the various places that were still calling rprintf()
                   2806:       with strerror() as an arg.
                   2807: 
                   2808:     - If an rsync daemon is listening on multiple sockets (to handle both
                   2809:       IPv4 and IPv6 to a single port), we now close all the unneeded file
                   2810:       handles after we accept a connection (we used to close just one of
                   2811:       them).
                   2812: 
                   2813:     - Optimized the handling of larger block sizes (rsync used to slow to a
                   2814:       crawl if the block size got too large).
                   2815: 
                   2816:     - Optimized away a loop in hash_search().
                   2817: 
                   2818:     - Some improvements to the sanitize_path() and clean_fname() functions
                   2819:       makes them more efficient and produce better results (while still
                   2820:       being compatible with the file-name cleaning that gets done on both
                   2821:       sides when sending the file-list).
                   2822: 
                   2823:     - Got rid of alloc_sanitize_path() after adding a destination-buffer
                   2824:       arg to sanitize_path() made it possible to put all the former's
                   2825:       functionality into the latter.
                   2826: 
                   2827:     - The file-list that is output when at least 4 verbose options are
                   2828:       specified reports the uid value on the sender even when rsync is
                   2829:       not running as root (since we might be sending to a root receiver).
                   2830: 
                   2831:   BUILD CHANGES:
                   2832: 
                   2833:     - Added a "gen" target to rebuild most of the generated files,
                   2834:       including configure, config.h.in, the man pages, and proto.h.
                   2835: 
                   2836:     - If "make proto" doesn't find some changes in the prototypes, the
                   2837:       proto.h file is left untouched (its time-stamp used to always be
                   2838:       updated).
                   2839: 
                   2840:     - The variable $STRIP (that is optionally set by the install-strip
                   2841:       target's rule) was changed to $INSTALL_STRIP because some systems
                   2842:       have $STRIP already set in the environment.
                   2843: 
                   2844:     - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
                   2845: 
                   2846:     - When cross-compiling, the gettimeofday() function is now assumed to
                   2847:       be a modern version that takes two-args (since we can't test it).
                   2848: 
                   2849:   DEVELOPER RELATED:
                   2850: 
                   2851:     - The scripts in the testsuite dir were cleaned up a bit and a few
                   2852:       new tests added.
                   2853: 
                   2854:     - Some new diffs were added to the patches dir, and some accepted
                   2855:       ones were removed.

                   2858: NEWS for rsync 2.6.2 (30 Apr 2004)
                   2859: Protocol: 28 (unchanged)
                   2860: Changes since 2.6.1:
                   2861: 
                   2862:   BUG FIXES:
                   2863: 
                   2864:     - Fixed a major bug in the sorting of the filenames when --relative
                   2865:       is used for some sources (just sources such as "/" and "/*" were
                   2866:       affected).  This fix ensures that we ask for the right file-list
                   2867:       item when requesting changes from the sender.
                   2868: 
                   2869:     - Rsync now checks the return value of the close() function to
                   2870:       better report disk-full problems on an NFS file system.
                   2871: 
                   2872:     - Restored the old daemon-server behavior of logging error messages
                   2873:       rather than returning them to the user.  (A better long-term fix
                   2874:       will be sought in the future.)
                   2875: 
                   2876:     - An obscure uninitialized-variable bug was fixed in the uid/gid
                   2877:       code.  (This bug probably had no ill effects.)
                   2878: 
                   2879:   BUILD CHANGES:
                   2880: 
                   2881:     - Got rid of the configure check for sys/sysctl.h (it wasn't used
                   2882:       and was causing a problem on some systems).  Also improved the
                   2883:       broken-largefile-locking test to try to avoid failure due to an
                   2884:       NFS build-dir.
                   2885: 
                   2886:     - Fixed a compile problem on systems that don't define
                   2887:       AI_NUMERICHOST.
                   2888: 
                   2889:     - Fixed a compile problem in the popt source for compilers that
                   2890:       don't support __attribute__.
                   2891:

                   2893: 
                   2894:     - Improved the testsuite's "merge" test to work on OSF1.
                   2895: 
                   2896:     - Two new diffs were added to the patches dir.

                   2899: NEWS for rsync 2.6.1 (26 Apr 2004)
                   2900: Protocol: 28 (changed)
                   2901: Changes since 2.6.0:
                   2902: 
                   2903:   SECURITY FIXES:
                   2904: 
                   2905:     - Paths sent to an rsync daemon are more thoroughly sanitized when
                   2906:       chroot is not used.  If you're running a non-read-only rsync
                   2907:       daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
                   2908:       user privs you run rsync under is anything above "nobody".
                   2909: 
                   2910:   ENHANCEMENTS:
                   2911: 
                   2912:     - Lower memory use, more optimal transfer of data over the socket,
                   2913:       and lower CPU usage (see the INTERNAL section for details).
                   2914: 
                   2915:     - The RSYNC_PROXY environment variable can now contain a
                   2916:       "USER:PASS@" prefix before the "HOST:PORT" information.
                   2917:       (Bardur Arantsson)
                   2918: 
                   2919:     - The --progress output now mentions how far along in the transfer
                   2920:       we are, including both a count of files transferred and a
                   2921:       percentage of the total file-count that we've processed.  It also
                   2922:       shows better current-rate-of-transfer and remaining-transfer-time
                   2923:       values.
                   2924: 
                   2925:     - Documentation changes now attempt to describe some often mis-
                   2926:       understood features more clearly.
                   2927: 
                   2928:   BUG FIXES:
                   2929: 
                   2930:     - When -x (--one-file-system) is combined with -L (--copy-links) or
                   2931:       --copy-unsafe-links, no symlinked files are skipped, even if the
                   2932:       referent file is on a different filesystem.
                   2933: 
                   2934:     - The --link-dest code now works properly for a non-root user when
                   2935:       (1) the UIDs of the source and destination differ and -o was
                   2936:       specified, or (2) when the group of the source can't be used on
                   2937:       the destination and -g was specified.
                   2938: 
                   2939:     - Fixed a bug in the handling of -H (hard-links) that might cause
                   2940:       the expanded PATH/NAME value of the current item to get
                   2941:       overwritten (due to an expanded-name caching bug).
                   2942:       
                   2943:     - We now reset the "new data has been sent" flag at the start of
                   2944:       each file we send.  This makes sure that an interrupted transfer
                   2945:       with the --partial option set doesn't keep a shorter temp file
                   2946:       than the current basis file when no new data has been transferred
                   2947:       over the wire for that file.
                   2948: 
                   2949:     - Fixed a byte-order problem in --batch-mode on big-endian machines.
                   2950:       (Jay Fenlason)
                   2951: 
                   2952:     - When using --cvs-exclude, the exclude items we get from a
                   2953:       per-directory's .cvsignore file once again only affect that one
                   2954:       directory (not all following directories too).  The items are also
                   2955:       now properly word-split and parsed without any +/- prefix parsing.
                   2956: 
                   2957:     - When specifying the USER@HOST: prefix for a file, the USER part
                   2958:       can now contain an '@', if needed (i.e. the last '@' is used to
                   2959:       find the HOST, not the first).
                   2960: 
                   2961:     - Fixed some bugs in the handling of group IDs for non-root users:
                   2962:       (1) It properly handles a group that the sender didn't have a name
                   2963:       for (it would previously skip changing the group on any files in
                   2964:       that group).  (2) If --numeric-ids is used, rsync no longer
                   2965:       attempts to set groups that the user doesn't have the permission
                   2966:       to set.
                   2967: 
                   2968:     - Fixed the "refuse options" setting in the rsyncd.conf file.
                   2969: 
                   2970:     - Improved the -x (--one-file-system) flag's handling of any mount-
                   2971:       point directories we encounter.  It is both more optimal (in that
                   2972:       it no longer does a useless scan of the contents of the mount-
                   2973:       point dirs) and also fixes a bug where a remapped mount of the
                   2974:       original filesystem could get discovered in a subdir we should be
                   2975:       ignoring.
                   2976: 
                   2977:     - Rsync no longer discards a double-slash at the start of a filename
                   2978:       when trying to open the file.  It also no longer constructs names
                   2979:       that start with a double slash (unless the user supplied them).
                   2980: 
                   2981:     - Path-specifying options to a daemon should now work the same with
                   2982:       or without chroot turned on.  Previously, such a option (such as
                   2983:       --link-dest) would get its absolute path munged into a relative
                   2984:       one if chroot was not on, making that setting fairly useless.
                   2985:       Rsync now transforms the path into one that is based on the
                   2986:       module's base dir when chroot is not enabled.
                   2987: 
                   2988:     - Fixed a compatibility problem interacting with older rsync
                   2989:       versions that might send us an empty --suffix value without
                   2990:       telling us that --backup-dir was specified.
                   2991: 
                   2992:     - The "hosts allow" option for a daemon-over-remote-shell process
                   2993:       now has improved support for IPv6 addresses and a fix for systems
                   2994:       that have a length field in their socket structs.
                   2995: 
                   2996:     - Fixed the ability to request an empty backup --suffix when sending
                   2997:       files to an rsync daemon.
                   2998: 
                   2999:     - Fixed an option-parsing bug when --files-from was sent to a server
                   3000:       sender.
                   3001: 
                   3002:   INTERNAL:
                   3003: 
                   3004:     - Most of the I/O is now buffered, which results in a pretty large
                   3005:       speedup when running under MS Windows.  (Craig Barratt)
                   3006: 
                   3007:     - Optimizations to the name-handling/comparing code have made some
                   3008:       significant reductions in user-CPU time for large file sets.
                   3009: 
                   3010:     - Some cleanup of the variable types make the code more consistent.
                   3011: 
                   3012:     - Reduced memory requirements of hard link preservation.
                   3013:       (J.W. Schultz)
                   3014: 
                   3015:     - Implemented a new algorithm for hard-link handling that speeds up
                   3016:       the code significantly.  (J.W. Schultz and Wayne Davison)
                   3017: 
                   3018:     - The --hard-link option now uses the first existing file in the
                   3019:       group of linked files as the basis for the transfer.  This
                   3020:       prevents the sub-optimal transfer of a file's data when a new
                   3021:       hardlink is added on the sending side and it sorts alphabetically
                   3022:       earlier in the list than the files that are already present on the
                   3023:       receiving side.
                   3024: 
                   3025:     - Dropped support for protocol versions less than 20 (2.3.0 released
                   3026:       15 Mar 1999) and activated warnings for protocols less than 25
                   3027:       (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
                   3028:       severally)
                   3029: 
                   3030:     - More optimal data transmission for --hard-links (protocol 28).
                   3031: 
                   3032:     - More optimal data transmission for --checksum (protocol 28).
                   3033: 
                   3034:     - Less memory is used when --checksum is specified.
                   3035: 
                   3036:     - Less memory is used in the file list (a per-file savings).
                   3037: 
                   3038:     - The generator is now better about not modifying the file list
                   3039:       during the transfer in order to avoid a copy-on-write memory
                   3040:       bifurcation (on systems where fork() uses shared memory).
                   3041:       Previously, rsync's shared memory would slowly become unshared,
                   3042:       resulting in real memory usage nearly doubling on the receiving
                   3043:       side by the end of the transfer.  Now, as long as permissions
                   3044:       are being preserved, the shared memory should remain that way
                   3045:       for the entire transfer.
                   3046: 
                   3047:     - Changed hardlink info and file_struct + strings to use allocation
                   3048:       pools.  This reduces memory use for large file-sets and permits
                   3049:       freeing memory to the OS.  (J.W. Schultz) 
                   3050: 
                   3051:     - The 2 pipes used between the receiver and generator processes
                   3052:       (which are forked on the same machine) were reduced to 1 pipe and
                   3053:       the protocol improved so that (1) it is now impossible to have the
                   3054:       "redo" pipe fill up and hang rsync, and (2) trailing messages from
                   3055:       the receiver don't get lost on their way through the generator
                   3056:       over to the sender (which mainly affected hard-link messages and
                   3057:       verbose --stats output).
                   3058: 
                   3059:     - Improved the internal uid/gid code to be more portable and a
                   3060:       little more optimized.
                   3061: 
                   3062:     - The device numbers sent when using --devices are now sent as
                   3063:       separate major/minor values with 32-bit accuracy (protocol 28).
                   3064:       Previously, the copied devices were sent as a single 32-bit
                   3065:       number.  This will make inter-operation of 64-bit binaries more
                   3066:       compatible with their 32-bit brethren (with both ends of the
                   3067:       connection are using protocol 28).  Note that optimizations in the
                   3068:       binary protocol for sending the device numbers often results in
                   3069:       fewer bytes being used than before, even though more precision is
                   3070:       now available.
                   3071: 
                   3072:     - Some cleanup of the exclude/include structures and its code made
                   3073:       things clearer (internally), simpler, and more efficient.
                   3074: 
                   3075:     - The reading & writing of the file-list in batch-mode is now
                   3076:       handled by the same code that sends & receives the list over the
                   3077:       wire.  This makes it much easier to maintain.  (Note that the
                   3078:       batch code is still considered to be experimental.)
                   3079: 
                   3080:   BUILD CHANGES:
                   3081: 
                   3082:     - The configure script now accepts --with-rsyncd-conf=PATH to
                   3083:       override the default value of the /etc/rsyncd.conf file.
                   3084: 
                   3085:     - Fixed configure bug when running "./configure --disable-ipv6".
                   3086: 
                   3087:     - Fixed compilation problem on Tru64 Unix (having to do with
                   3088:       sockaddr.sa_len and sockaddr.sin_len).
                   3089: 
                   3090:   DEVELOPER RELATED:
                   3091: 
                   3092:     - Fixed "make test" bug when build dir is not the source dir.
                   3093: 
                   3094:     - Added a couple extra diffs in the "patches" dir, removed the ones
                   3095:       that got applied, and rebuilt the rest.
                   3096:

                   3098: NEWS for rsync 2.6.0 (1 Jan 2004)
                   3099: Protocol: 27 (changed)
                   3100: Changes since 2.5.7:
                   3101: 
                   3102:   ENHANCEMENTS:
                   3103: 
                   3104:     * "ssh" is now the default remote shell for rsync.  If you want to
                   3105:       change this, configure like this:  "./configure --with-rsh=rsh".
                   3106: 
                   3107:     * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
                   3108:       Note that --from0 affects the line-ending character for all the
                   3109:       files read by the --*-from options. (Wayne Davison)
                   3110: 
                   3111:     * Length of csum2 is now per-file starting with protocol version
                   3112:       27. (J.W. Schultz)
                   3113: 
                   3114:     * Per-file dynamic block size is now sqrt(file length).  The
                   3115:       per-file checksum size is determined according to an algorithm
                   3116:       provided by Donovan Baarda which reduces the probability of rsync
                   3117:       algorithm corrupting data and falling back using the whole md4
                   3118:       checksums. (J.W. Schultz, Donovan Baarda)
                   3119: 
                   3120:     * The --stats option no longer includes the (debug) malloc summary
                   3121:       unless the verbose option was specified at least twice.
                   3122: 
                   3123:     * Added a new error/warning code for when files vanish from the
                   3124:       sending side.  Made vanished source files not interfere with the
                   3125:       file-deletion pass when --delete-after was specified.
                   3126: 
                   3127:     * Various trailing-info sections are now preceded by a newline.
                   3128: 
                   3129:   BUG FIXES:
                   3130: 
                   3131:     * Fixed several exclude/include matching bugs when using wild-cards.
                   3132:       This has a several user-visible effects, all of which make the
                   3133:       matching more consistent and intuitive.  This should hopefully not
                   3134:       cause anyone problems since it makes the matching work more like
                   3135:       what people are expecting. (Wayne Davison)
                   3136: 
                   3137:       - A pattern with a "**" no longer causes a "*" to match slashes.
                   3138:         For example, with "/*/foo/**", "foo" must be 2 levels deep.
                   3139:        [If your string has BOTH "*" and "**" wildcards, changing the
                   3140:        "*" wildcards to "**" will provide the old behavior in all
                   3141:        versions.]
                   3142: 
                   3143:       - "**/foo" now matches at the base of the transfer (like /foo
                   3144:         does).  [Use "/**/foo" to get the old behavior in all versions.]
                   3145: 
                   3146:       - A non-anchored wildcard term floats to match beyond the base of
                   3147:         the transfer.  E.g. "CVS/R*" matches at the end of the path,
                   3148:         just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
                   3149:         to get the old behavior in all versions.]
                   3150: 
                   3151:       - Including a "**" in the match term causes it to be matched
                   3152:         against the entire path, not just the name portion, even if
