rsync 3.1.2

    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
  354: 
  355:   DEVELOPER RELATED:
  356: 
  357:     - Added more conditional debug output.
  358: 
  359:     - Fixed some build issues for android and minix.
  360: 
  361: NEWS for rsync 3.0.9 (23 Sep 2011)
  362: Protocol: 30 (unchanged)
  363: Changes since 3.0.8:
  364: 
  365:   BUG FIXES:
  366: 
  367:     - Fix a crash bug in checksum scanning when --inplace is used.
  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.
  380: 
  381:     - Fix --fake-super's interaction with --link-dest same-file comparisons.
  382: 
  383:     - Fix the updating of the curr_dir buffer to avoid a duplicate slash.
  384: 
  385:     - Fix the directory permissions on an implied dot-dir when using --relative
  386:       (e.g. /outside/path/././send/path).
  387: 
  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: 
  397:     - Failing to use a password file that was specified on the command-line is
  398:       now a fatal error.
  399: 
  400:     - Fix the non-root updating of directories that don't have the read and/or
  401:       execute permission.
  402: 
  403:     - Make daemon-excluded file errors more error-like.
  404: 
  405:     - Fix a compilation issue on older C compilers (due to a misplaced var
  406:       declaration).
  407: 
  408:     - Make configure avoid finding socketpair on cygwin.
  409: 
  410:     - Avoid trying to reference SO_BROADCAST if the OS doesn't support it.
  411: 
  412:     - Fix some issues with the post-processing of the man pages.
  413: 
  414:     - Fixed the user home-dir handling in the support/lsh script.
  415: 
  416:     - Some minor manpage improvements.

  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
  431:       hard-linking code, and some potential failed checksums (via -c) that
  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: 
  614:   DEVELOPER RELATED:
  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.

  623: NEWS for rsync 3.0.6 (8 May 2009)
  624: Protocol: 30 (unchanged)
  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.
  651: 
  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
  655:       receiving side when a mount-point directory did not match a directory in
  656:       the transfer.
  657: 
  658:     - Fixed the dropping of an ACL mask when no named ACL values were present.
  659: 
  660:     - Fixed an ACL/xattr corruption issue where the --backup option could cause
  661:       rsync to associate the wrong ACL/xattr information with received files.
  662: 
  663:     - Fixed the use of --xattrs with --only-write-batch.
  664: 
  665:     - Fixed the use of --dry-run with --read-batch.
  666: 
  667:     - Fixed configure's erroneous use of target.
  668: 
  669:     - Fixed configure's --disable-debug option.
  670: 
  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: 
  677:     - Fixed an failure transferring special files from Solaris to Linux.

  679: 
  680: NEWS for rsync 3.0.5 (28 Dec 2008)
  681: Protocol: 30 (unchanged)
  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
  704:       file when the root of the transfer isn't the current directory.
  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-
  733:       transfer warning.
  734: 
  735:     - Allow a path with a leading "//" to be preserved (CYGWIN only).
  736: 
  737:   ENHANCEMENTS:
  738: 
  739:     - Made the support/atomic-rsync script able to perform a fully atomic
  740:       update of the copied hierarchy when the destination is setup using a
  741:       particular symlink idiom.
  742: 
  743: 
  744: NEWS for rsync 3.0.4 (6 Sep 2008)
  745: Protocol: 30 (unchanged)
  746: Changes since 3.0.3:
  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).
  788: 
  789:   ENHANCEMENTS:
  790: 
  791:     - Rsync will avoid sending an -e option to the server if an older protocol
  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.
  797: 
  798:   DEVELOPER RELATED:
  799: 
  800:     - The Makefile will not halt for just a timestamp change on the Makefile
  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"
  804:       instead of "$RSYNC".
  805: 
  806:     - Enhanced the release scripts to be able to handle a branch release and
  807:       to do even more consistency checks on the files.

  810: NEWS for rsync 3.0.3 (29 Jun 2008)
  811: Protocol: 30 (unchanged)
  812: Changes since 3.0.2:
  813: 
  814:   BUG FIXES:
  815: 
  816:     - Fixed a wildcard matching problem in the daemon when a module has
  817:       "use chroot" enabled.
  818: 
  819:     - Fixed a crash bug in the hard-link code.
  820: 
  821:     - Fixed the sending of xattr directory information when the code finds a
  822:       --link-dest or --copy-dest directory with unchanged xattrs -- the
  823:       destination directory now gets these unchanged xattrs properly applied.
  824: 
  825:     - Fixed an xattr-sending glitch that could cause an "Internal abbrev"
  826:       error.
  827: 
  828:     - Fixed the combination of --xattrs and --backup.
  829: 
  830:     - The generator no longer allows a '.' dir to be excluded by a daemon-
  831:       exclude rule.
  832: 
  833:     - Fixed deletion handling when copying a single, empty directory (with no
  834:       files) to a differently named, non-existent directory.
  835: 
  836:     - Fixed the conversion of spaces into dashes in the %M log escape.
  837: 
  838:     - Fixed several places in the code that were not returning the right
  839:       errno when a function failed.
  840: 
  841:     - Fixed the backing up of a device or special file into a backup dir.
  842: 
  843:     - Moved the setting of the socket options prior to the connect().
  844: 
  845:     - If rsync exits in the middle of a --progress output, it now outputs a
  846:       newline to help prevent the progress line from being overwritten.
  847: 
  848:     - Fixed a problem with how a destination path with a trailing slash or
  849:       a trailing dot-dir was compared against the daemon excludes.
  850: 
  851:     - Fixed the sending of large (size > 16GB) files when talking to an older
  852:       rsync (protocols < 30):  we now use a compatible block size limit.
  853: 
  854:     - If a file's length is so huge that we overflow a checksum buffer count
  855:       (i.e. several hundred TB), warn the user and avoid sending an invalid
  856:       checksum struct over the wire.
  857: 
  858:     - If a source arg is excluded, --relative no longer adds the excluded
  859:       arg's implied dirs to the transfer.  This fix also made the exclude
  860:       check happen in the better place in the sending code.
  861: 
  862:     - Use the overflow_exit() function for overflows, not out_of_memory().
  863: 
  864:     - Improved the code to better handle a system that has only 32-bit file
  865:       offsets.
  866: 
  867:   ENHANCEMENTS:
  868: 
  869:     - The rsyncd.conf manpage now consistently refers to the parameters in
  870:       the daemon config file as "parameters".
  871: 
  872:     - The description of the --inplace option was improved.
  873: 
  874:   EXTRAS:
  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.
  879: 
  880:   DEVELOPER RELATED:
  881: 
  882:     - Fixed a testcase failure if the tests are run as root and made some
  883:       compatibility improvements.
  884: 
  885:     - Improved the daemon tests, including checking module comments, the
  886:       listing of files, and the ensuring that daemon excludes can't affect
  887:       a dot-dir arg.
  888: 
  889:     - Improved some build rules for those that build in a separate directory
  890:       from the source, including better install rules for the man pages, and
  891:       the fixing of a proto.h-tstamp rule that could make the binaries get
  892:       rebuild without cause.
  893: 
  894:     - Improved the testsuite to work around a problem with some utilities
  895:       (e.g. cp -p & touch -r) rounding sub-second timestamps.
  896: 
  897:     - Ensure that the early patches don't cause any generated-file hunks to
  898:       bleed-over into patches that follow.

  903: Changes since 3.0.1:
  904: 
  905:   BUG FIXES:
  906: 
  907:     - Fixed a potential buffer overflow in the xattr code.
  908:

  921: NEWS for rsync 3.0.1 (3 Apr 2008)
  922: Protocol: 30 (unchanged)
  923: Changes since 3.0.0:
  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.
 1021: 
 1022:   INTERNAL:
 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.
 1035: 
 1036:   DEVELOPER RELATED:
 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
 1048:       expect hard-linked symlinks or not.
 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
 1053:       rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
 1054: 
 1055:     - Updated the build scripts to work with a revised FTP directory
 1056:       structure.

 1059: NEWS for rsync 3.0.0 (1 Mar 2008)
 1060: Protocol: 30 (changed)
 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: 
 1406: 
 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.

 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).
 1636: 
 1637: 
 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.
 2023: 
 2024: 
 2025: NEWS for rsync 2.6.5 (1 Jun 2005)
 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.

 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.

 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: 
 2892:   DEVELOPER RELATED:
 2893: 
 2894:     - Improved the testsuite's "merge" test to work on OSF1.
 2895: 
 2896:     - Two new diffs were added to the patches dir.
 2897: 
 2898: 
 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.

 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
 3153:         there aren't any interior slashes in the term.  E.g. "foo**bar"
 3154:         would exclude "/path/foo-bar" (just like before) as well as
 3155:         "/foo-path/baz-bar" (unlike before).  [Use "foo*bar" to get the
 3156:         old behavior in all versions.]
 3157: 
 3158:     * The exclude list specified in the daemon's config file is now
 3159:       properly applied to the pulled items no matter how deep the
 3160:       user's file-args are in the source tree.  (Wayne Davison)
 3161: 
 3162:     * For protocol version >= 27, mdfour_tail() is called when the
 3163:       block size (including checksum_seed) is a multiple of 64.
 3164:       Previously it was not called, giving the wrong MD4 checksum.
 3165:       (Craig Barratt)
 3166: 
 3167:     * For protocol version >= 27, a 64 bit bit counter is used in
 3168:       mdfour.c as required by the RFC.  Previously only a 32 bit bit
 3169:       counter was used, causing incorrect MD4 file checksums for
 3170:       file sizes >= 512MB - 4.  (Craig Barratt)
 3171: 
 3172:     * Fixed a crash bug when interacting with older rsync versions and
 3173:       multiple files of the same name are destined for the same dir.
 3174:       (Wayne Davison)
 3175: 
 3176:     * Keep tmp names from overflowing MAXPATHLEN.
 3177: 
 3178:     * Make --link-dest honor the absence of -p, -o, and -g.
 3179: 
 3180:     * Made rsync treat a trailing slash in the destination in a more
 3181:       consistent manner.
 3182: 
 3183:     * Fixed file I/O error detection.  (John Van Essen)
 3184: 
 3185:     * Fixed bogus "malformed address {hostname}" message in rsyncd log
 3186:       when checking IP address against hostnames from "hosts allow"
 3187:       and "hosts deny" parameters in config file.
 3188: 
 3189:     * Print heap statistics when verbose >= 2 instead of when >= 1.
 3190: 
 3191:     * Fixed a compression (-z) bug when syncing a mostly-matching file
 3192:       that contains already-compressed data.  (Yasuoka Masahiko and
 3193:       Wayne Davison)
 3194: 
 3195:     * Fixed a bug in the --backup code that could cause deleted files
 3196:       to not get backed up.
 3197: 
 3198:     * When the backup code makes new directories, create them with mode
 3199:       0700 instead of 0755 (since the directory permissions in the
 3200:       backup tree are not yet copied from the main tree).
 3201: 
 3202:     * Call setgroups() in a more portable manner.
 3203: 
 3204:     * Improved file-related error messages to better indicate exactly
 3205:       what pathname failed. (Wayne Davison)
 3206: 
 3207:     * Fixed some bugs in the handling of --delete and --exclude when
 3208:       using the --relative (-R) option. (Wayne Davison)
 3209: 
 3210:     * Fixed bug that prevented regular files from replacing
 3211:       special files and caused a directory in --link-dest or
 3212:       --compare-dest to block the creation of a file with the
 3213:       same path.  A directory still cannot be replaced by a
 3214:       regular file unless --delete specified.  (J.W. Schultz)
 3215: 
 3216:     * Detect and report when open or opendir succeed but read and
 3217:       readdir fail caused by network filesystem issues and truncated
 3218:       files.  (David Norwood, Michael Brown, J.W. Schultz)
 3219: 
 3220:     * Added a fix that should give ssh time to restore the tty settings
 3221:       if the user presses Ctrl-C at an ssh password prompt.
 3222: 
 3223:   INTERNAL:
 3224: 
 3225:     * Eliminated vestigial support for old versions that we stopped
 3226:       supporting. (J.W. Schultz)
 3227: 
 3228:     * Simplified some of the option-parsing code. (Wayne Davison)
 3229: 
 3230:     * Some cleanup made to the exclude code, as well as some new
 3231:       defines added to enhance readability. (Wayne Davison)
 3232: 
 3233:     * Changed the protocol-version code so that it can interact at a
 3234:       lower protocol level than the maximum supported by both sides.
 3235:       Added an undocumented option, --protocol=N, to force the value
 3236:       we advertise to the other side (primarily for testing purposes).

 3253: 
 3254:   ENHANCEMENTS:
 3255: 
 3256:     * The --delete-after option now implies --delete.  (Wayne Davison)
 3257: 
 3258:     * The --suffix option can now be used with --backup-dir.  (Michael
 3259:       Zimmerman)
 3260: 
 3261:     * Combining "::" syntax with the --rsh/-e option now uses the
 3262:       specified remote-shell as a transport to talk to a (newly-spawned)
 3263:       server-daemon.  This allows someone to use daemon features, such
 3264:       as modules, over a secure protocol, such as ssh.  (JD Paul)

 3284: 
 3285:     * Changed exclude file handling to permit DOS or MAC style line

 3294:       L. Allen, Martin Pool)
 3295: 
 3296:     * Generate each file's rolling-checksum data as we send it, not

 3396:     * Merge in changes from zlib 1.1.3 to zlib 1.1.4.  (Jos Backus)
 3397:       (Note that rsync still uses a custom version of zlib; you can
 3398:       not just link against a system library.  See zlib/README.rsync)

 3408: 
 3409:     * Make sure that supplementary groups are removed from a server
 3410:       process after changing uid and gid. (Ethan Benson) (Debian bug
 3411:       #132272, CVE CAN-2002-0080)
 3412: 
 3413:   BUG FIXES:
 3414: 
 3415:     * Fix zlib double-free bug.  (Owen Taylor, Mark J Cox) (CVE
 3416:       CAN-2002-0059)
 3417: 
 3418:     * Fixed problem that in many cases caused the error message
 3419: 	unexpected read size of 0 in map_ptr
 3420:       and resulted in the wrong data being copied.
 3421: 
 3422:     * Fixed compilation errors on some systems caused by the use of
 3423:       "unsigned int64" in rsync.h.
 3424: 
 3425:     * Fixed problem on systems such as Sunos4 that do not support realloc
 3426:       on a NULL pointer; error was "out of memory in flist_expand".
 3427: 
 3428:     * Fix for rsync server processes hanging around after the client
 3429:       unexpectedly disconnects.  (Colin Walters) (Debian bug #128632)
 3430: 
 3431:     * Cope with BSD systems on which mkdir() will not accept a trailing
 3432:       slash.
 3433: 
 3434:   ENHANCEMENTS:
 3435: 
 3436:     * Merge in changes from zlib 1.1.2 to zlib 1.1.3.  (Note that
 3437:       rsync still uses a custom version of zlib; you can not just link
 3438:       against a system library.  See zlib/README.rsync)
 3439: 
 3440:     * Command to initiate connections is only shown with -vv, rather
 3441:       than -v as in 2.5.2.  Output from plain -v is more similar to
 3442:       what was historically used so as not to break scripts that try
 3443:       to parse the output.
 3444: 
 3445:     * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
 3446: 
 3447:     * Made the --write-batch and --read-batch options actually work
 3448:       and added documentation in the man page (Jos Backus)
 3449: 
 3450:     * If the daemon is unable to fork a child to accept a connection,
 3451:       print an error message.  (Colin Walters)

 3456: Changes since 2.5.1:
 3457: 
 3458:   SECURITY FIXES:
 3459: 
 3460:     * Signedness security patch from Sebastian Krahmer
 3461:       <krahmer@suse.de> -- in some cases we were not sufficiently
 3462:       careful about reading integers from the network.
 3463: 
 3464:   BUG FIXES:
 3465: 
 3466:     * Fix possible string mangling in log files.
 3467: 
 3468:     * Fix for setting local address of outgoing sockets.
 3469: 
 3470:     * Better handling of hardlinks and devices on platforms with
 3471:       64-bit dev_t or ino_t.
 3472: 
 3473:     * Name resolution on machines supporting IPv6 is improved.
 3474: 
 3475:     * Fix for device nodes.  (dann frazier)   (Debian #129135)
 3476: 
 3477:   ENHANCEMENTS:
 3478: 
 3479:     * With -v, rsync now shows the command used to initiate an ssh/rsh
 3480:       connection.
 3481: 
 3482:     * --statistics now shows memory heap usage on platforms that
 3483:       support mallinfo().
 3484: 
 3485:     * "The Ted T'so school of program optimization": make progress
 3486:       visible and people will think it's faster.  (With --progress,
 3487:       rsync will show you how many files it has seen as it builds the
 3488:       file_list, giving some indication that it has not hung.)
 3489: 
 3490:     * Improvements to batch mode support.  This is still experimental
 3491:       but testing would be welcome.   (Jos Backus)
 3492: 
 3493:     * New --ignore-existing option, patch previously distributed with
 3494:       Vipul's Razor.  (Debian #124286)

 3508:       Hagino)
 3509: 
 3510:     * Various fixes for IPv6 support.  (Dave Dykstra)
 3511: 
 3512:     * rsync.1 typo fix.  (Matt Kraai)
 3513: 
 3514:     * Test suite typo fixes.  (Tom Schmidt)

 3516:     * rsync.1 grammar and clarity improvements.  (Edward
 3517:       Welbourne)
 3518:

 3520: 
 3521:   ENHANCEMENTS:
 3522: 
 3523:     * --progress and -P now show estimated data transfer rate (in a
 3524:       multiple of bytes/s) and estimated time to completion.  (Rik
 3525:       Faith)
 3526: 
 3527:     * --no-detach option, required to run as a W32 service and also
 3528:       useful when running on Unix under daemontools, AIX's SRC, or a
 3529:       debugger.  (Max Bowsher, Jos Backus)
 3530:

 3537: 
 3538:   ANNOUNCEMENTS
 3539: 
 3540:     * Martin Pool <mbp@samba.org> is now a co-maintainer.
 3541: 
 3542:   NEW FEATURES
 3543: 
 3544:     * Support for LSB-compliant packaging <http://www.linuxbase.org/>
 3545: 
 3546:     * Shell wildcards are allowed in "auth users" lines.
 3547: 
 3548:     * Merged UNC rsync+ patch to support creation of standalone patch
 3549:       sets.  By Bert J. Dempsey and Debra Weiss, updated by Jos
 3550:       Backus.  <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
 3551: 
 3552:     * IPv6 support based on a patch from KAME.net, on systems
 3553:       including modern versions of Linux, Solaris, and HP-UX.  Also
 3554:       includes IPv6 compatibility functions for old OSs by the
 3555:       Internet Software Consortium, Paul Vixie, the OpenSSH
 3556:       portability project, and OpenBSD.
 3557: 
 3558:   ENHANCEMENTS
 3559: 
 3560:     * Include/exclude cluestick: with -vv, print out whether files are
 3561:       included or excluded and why.
 3562: 
 3563:     * Many error messages have more friendly explanations and more
 3564:       details.
 3565: 
 3566:     * Manual page improvements plus scanty protocol documentation.
 3567: 
 3568:     * When running as --daemon in the background and using a "log
 3569:       file" rsyncd.conf directive, close the log file every time it is
 3570:       open when going to sleep on the socket.  This allows the log
 3571:       file to get cleaned out by another process.
 3572: 
 3573:     * Change to using libpopt rather than getopt for processing
 3574:       options.	This makes the code cleaner and the behaviour more
 3575:       consistent across platforms.  popt is included and built if not
 3576:       installed on the platform.
 3577: 
 3578:     * More details in --version, including note about whether 64-bit
 3579:       files, symlinks and hardlinks are supported.
 3580: 
 3581:     * MD4 code may use less CPU cycles.
 3582: 
 3583:     * Use mkstemp on systems where it is secure.  If we use mktemp,
 3584:       explain that we do it in a secure way.
 3585: 
 3586:     * --whole-file is the default when source and target are on the
 3587: 	local machine.
 3588: 
 3589:   BUG FIXES:
 3590: 
 3591:     * Fix for various bugs causing rsync to hang.
 3592: 
 3593:     * Attempt to fix Large File Summit support on AIX.
 3594: 
 3595:     * Attempt to fix error handling lockup bug.
 3596: 
 3597:     * Give a non-0 exit code if *any* of the files we have been asked
 3598:       to transfer fail to transfer.
 3599: 
 3600:     * For log messages containing ridiculously long strings that might
 3601:       overflow a buffer rsync no longer aborts, but rather prints an
 3602:       ellipsis at the end of the string.  (Patch from Ed Santiago.)
 3603: 
 3604:   PLATFORMS:
 3605: 
 3606:     * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
 3607: 
 3608:     * autoconf2.52 (or later) is now required to rebuild the autoconf
 3609:       scripts.  It is not required to simply build rsync.
