    1: NEWS for rsync 3.0.9 (23 Sep 2011)
    2: Protocol: 30 (unchanged)
    3: Changes since 3.0.8:
    4: 
    5:   BUG FIXES:
    6: 
    7:     - Fix a crash bug in checksum scanning when --inplace is used.
    8: 
    9:     - Fix a hang if a hard-linked file cannot be opened by the sender (e.g.
   10:       if it has no read permission).
   11: 
   12:     - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
   13: 
   14:     - Fix a memory leak in the xattr code.
   15: 
   16:     - Fixed a bug with --delete-excluded when a filter merge file has a rule
   17:       that specifies a receiver-only side restriction.
   18: 
   19:     - Fix a bug with the modifying of unwritable directories.
   20: 
   21:     - Fix --fake-super's interaction with --link-dest same-file comparisons.
   22: 
   23:     - Fix the updating of the curr_dir buffer to avoid a duplicate slash.
   24: 
   25:     - Fix the directory permissions on an implied dot-dir when using --relative
   26:       (e.g. /outside/path/././send/path).
   27: 
   28:     - Fixed some too-long sleeping instances when using --bwlimit.
   29: 
   30:     - Fixed when symlink ownership difference-checking gets compiled into
   31:       unchanged_attrs().
   32: 
   33:     - Improved the socket-error reporting when multiple protocols fail.
   34: 
   35:     - Fixed a case where a socket error could reference just-freed memory.
   36: 
   37:     - Failing to use a password file that was specified on the command-line is
   38:       now a fatal error.
   39: 
   40:     - Fix the non-root updating of directories that don't have the read and/or
   41:       execute permission.
   42: 
   43:     - Make daemon-excluded file errors more error-like.
   44: 
   45:     - Fix a compilation issue on older C compilers (due to a misplaced var
   46:       declaration).
   47: 
   48:     - Make configure avoid finding socketpair on cygwin.
   49: 
   50:     - Avoid trying to reference SO_BROADCAST if the OS doesn't support it.

   58: NEWS for rsync 3.0.8 (26 Mar 2011)
   59: Protocol: 30 (unchanged)
   60: Changes since 3.0.7:
   61: 
   62:   BUG FIXES:
   63: 
   64:     - Fixed two buffer-overflow issues: one where a directory path that is
   65:       exactly MAXPATHLEN was not handled correctly, and one handling a
   66:       --backup-dir that is extra extra large.
   67: 
   68:     - Fixed a data-corruption issue when preserving hard-links without
   69:       preserving file ownership, and doing deletions either before or during
   70:       the transfer (CVE-2011-1097).  This fixes some assert errors in the
   71:       hard-linking code, and some potential failed checksums (via -c) that
   72:       should have matched.
   73: 
   74:     - Fixed a potential crash when an rsync daemon has a filter/exclude list
   75:       and the transfer is using ACLs or xattrs.
   76: 
   77:     - Fixed a hang if a really large file is being processed by an rsync that
   78:       can't handle 64-bit numbers.  Rsync will now complain about the file
   79:       being too big and skip it.
   80: 
   81:     - For devices and special files, we now avoid gathering useless ACL and/or
   82:       xattr information for files that aren't being copied.  (The un-copied
   83:       files are still put into the file list, but there's no need to gather
   84:       data that is not going to be used.)  This ensures that if the user uses
   85:       --no-D, that rsync can't possibly complain about being unable to gather
   86:       extended information from special files that are in the file list (but
   87:       not in the transfer).
   88: 
   89:     - Properly handle requesting remote filenames that start with a dash.  This
   90:       avoids a potential error where a filename could be interpreted as a
   91:       (usually invalid) option.
   92: 
   93:     - Fixed a bug in the comparing of upper-case letters in file suffixes for
   94:       --skip-compress.
   95: 
   96:     - If an rsync daemon has a module configured without a path setting, rsync
   97:       will now disallow access to that module.
   98: 
   99:     - If the destination arg is an empty string, it will be treated as a
  100:       reference to the current directory (as 2.x used to do).
  101: 
  102:     - If rsync was compiled with a newer time-setting function (such as
  103:       lutimes), rsync will fall-back to an older function (such as utimes) on a
  104:       system where the newer function is not around.  This helps to make the
  105:       rsync binary more portable in mixed-OS-release situations.
  106: 
  107:     - Fixed a batch-file writing bug that would not write out the full set of
  108:       compatibility flags that the transfer was using.  This fixes a potential
  109:       protocol problem for a batch file that contains a sender-side I/O error:
  110:       it would have been sent in a way that the batch-reader wasn't expecting.
  111: 
  112:     - Some improvements to the hard-linking code to ensure that device-number
  113:       hashing is working right, and to supply more information if the hard-link
  114:       code fails.
  115: 
  116:     - The --inplace code was improved to not search for an impossible checksum
  117:       position.  The quadruple-verbose chunk[N] message will now mention when
  118:       an inplace chunk was handled by a seek rather than a read+write.
  119: 
  120:     - Improved ACL mask handling, e.g. for Solaris.
  121: 
  122:     - Fixed a bug that prevented --numeric-ids from disabling the translation
  123:       of user/group IDs for ACLs.
  124: 
  125:     - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
  126:       option (e.g. --link-dest) could output an error trying to itemize the
  127:       changes against the alt-dest directory's xattr/ACL info but was instead
  128:       trying to access the not-yet-existing new destination directory.
  129: 
  130:     - Improved xattr system-error messages to mention the full path to the
  131:       file.
  132: 
  133:     - The --link-dest checking for identical symlinks now avoids considering
  134:       attribute differences that cannot be changed on the receiver.
  135: 
  136:     - Avoid trying to read/write xattrs on certain file types for certain OSes.
  137:       Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
  138:       NO_SPECIAL_XATTRS defines in config.h.
  139: 
  140:     - Improved the unsafe-symlink errors messages.
  141: 
  142:     - Fixed a bug setting xattrs on new files that aren't user writable.
  143: 
  144:     - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
  145: 
  146:     - Fixed a bug with --fake-super when copying files and dirs that aren't
  147:       user writable.
  148: 
  149:     - Fixed a bug where a sparse file could have its last sparse block turned
  150:       into a real block when rsync sets the file size (requires ftruncate).
  151: 
  152:     - If a temp-file name is too long, rsync now avoids truncating the name in
  153:       the middle of adjacent high-bit characters.  This prevents a potential
  154:       filename error if the filesystem doesn't allow a name to contain an
  155:       invalid multi-byte sequence.
  156: 
  157:     - If a muli-protocol socket connection fails (i.e., when contacting a
  158:       daemon), we now report all the failures, not just the last one.  This
  159:       avoids losing a relevant error (e.g. an IPv4 connection-refused error)
  160:       that happened before the final error (e.g. an IPv6 protocol-not-supported
  161:       error).
  162: 
  163:     - Generate a transfer error if we try to call chown with a -1 for a uid or
  164:       a gid (which is not settable).
  165: 
  166:     - Fixed the working of --force when used with --one-file-system.
  167: 
  168:     - Fix the popt arg parsing so that an option that doesn't take an arg will
  169:       reject an attempt to supply one (can configure --with-included-popt if
  170:       your system's popt library doesn't yet have this fix).
  171: 
  172:     - A couple minor option tweaks to the support/rrsync script, and also some
  173:       regex changes that make vim highlighting happier.
  174: 
  175:     - Fixed some issues in the support/mnt-excl script.
  176: 
  177:     - Various manpage improvements.
  178: 
  179:   ENHANCEMENTS:
  180: 
  181:     - Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).
  182: 
  183:   DEVELOPER RELATED:
  184: 
  185:     - Use lchmod() whenever it is available (not just on symlinks).
  186: 
  187:     - A couple fixes to the socketpair_tcp() routine.
  188: 
  189:     - Updated the helper scripts in the packaging subdirectory.
  190: 
  191:     - Renamed configure.in to configure.ac.
  192: 
  193:     - Fixed configure's checking for iconv routines for newer OS X versions.
  194: 
  195:     - Fixed the testsuite/xattrs.test script on OS X.

  197: NEWS for rsync 3.0.7 (31 Dec 2009)
  198: Protocol: 30 (unchanged)
  199: Changes since 3.0.6:
  200: 
  201:   BUG FIXES:
  202: 
  203:     - Fixed a bogus free when using --xattrs with --backup.
  204: 
  205:     - Avoid an error when --dry-run  was trying to stat a prior hard-link file
  206:       that hasn't really been created.
  207: 
  208:     - Fixed a problem with --compress (-z) where the receiving side could
  209:       return the error "inflate (token) returned -5".
  210: 
  211:     - Fixed a bug where --delete-during could delete in a directory before it
  212:       noticed that the sending side sent an I/O error for that directory (both
  213:       sides of the transfer must be at least 3.0.7).
  214: 
  215:     - Improved --skip-compress's error handling of bad character-sets and got
  216:       rid of a lingering debug fprintf().
  217: 
  218:     - Fixed the daemon's conveyance of io_error value from the sender.
  219: 
  220:     - An rsync daemon use seteuid() (when available) if it used setuid().
  221: 
  222:     - Get the permissions right on a --fake-super transferred directory that
  223:       needs more owner permissions to emulate root behavior.
  224: 
  225:     - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
  226:       its modifier when sending the filter rules to the remote rsync.
  227: 
  228:     - Improved the "--delete does not work without -r or -d" message.
  229: 
  230:     - Improved rsync's handling of --timeout to avoid a weird timeout case
  231:       where the sender could timeout even though it has recently written data
  232:       to the socket (but hasn't read data recently, due to the writing).
  233: 
  234:     - Some misc manpage improvements.
  235: 
  236:     - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
  237: 
  238:     - Make sure that a timeout specified in the daemon's config is used as a
  239:       maximum timeout value when the user also specifies a timeout.
  240: 
  241:     - Improved the error-exit reporting when rsync gets an error trying to
  242:       cleanup after an error:  the initial error is reported.
  243: 
  244:     - Improved configure's detection of IPv6 for solaris and cygwin.
  245: 
  246:     - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
  247: 
  248:     - Made our (only used if missing) getaddrinfo() routine use inet_pton()
  249:       (which we also provide) instead of inet_aton().
  250: 
  251:     - The exit-related debug messages now mention the program's role so it is
  252:       clear who output what message.
  253: 
  254:   DEVELOPER RELATED:
  255: 
  256:     - Got rid of type-punned compiler warnings output by newer gcc versions.
  257: 
  258:     - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
  259: 
  260:     - The testsuite no longer uses "id -u", so it works better on solaris.
  261: 
  262: 
  263: NEWS for rsync 3.0.6 (8 May 2009)
  264: Protocol: 30 (unchanged)
  265: Changes since 3.0.5:
  266: 
  267:   BUG FIXES:
  268: 
  269:     - Fixed a --read-batch hang when rsync is reading a batch file that was
  270:       created from an incremental-recursion transfer.
  271: 
  272:     - Fixed the daemon's socket code to handle the simultaneous arrival of
  273:       multiple connections.
  274: 
  275:     - Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
  276:       have consecutive slashes in the value.
  277: 
  278:     - Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
  279: 
  280:     - The sender now skips a (bogus) symlink that has a 0-length value, which
  281:       avoids a transfer error in the receiver.
  282: 
  283:     - Fixed a case where the sender could die with a tag-0 error if there was
  284:       an I/O during the sending of the file list.
  285: 
  286:     - Fixed the rrsync script to avoid a server-side problem when -e is at the
  287:       start of the short options.
  288: 
  289:     - Fixed a problem where a vanished directory could turn into an exit code
  290:       23 instead of the proper exit code 24.
  291: 
  292:     - Fixed the --iconv conversion of symlinks when doing a local copy.
  293: 
  294:     - Fixed a problem where --one-file-system was not stopping deletions on the
  295:       receiving side when a mount-point directory did not match a directory in
  296:       the transfer.
  297: 
  298:     - Fixed the dropping of an ACL mask when no named ACL values were present.
  299: 
  300:     - Fixed an ACL/xattr corruption issue where the --backup option could cause
  301:       rsync to associate the wrong ACL/xattr information with received files.
  302: 
  303:     - Fixed the use of --xattrs with --only-write-batch.
  304: 
  305:     - Fixed the use of --dry-run with --read-batch.
  306: 
  307:     - Fixed configure's erroneous use of target.
  308: 
  309:     - Fixed configure's --disable-debug option.
  310: 
  311:     - Fixed a run-time issue for systems that can't find iconv_open() by adding
  312:       the --disable-iconv-open configure option.
  313: 
  314:     - Complain and die if the user tries to combine --remove-source-files (or
  315:       the deprecated --remove-sent-files) with --read-batch.
  316: 
  317:     - Fixed an failure transferring special files from Solaris to Linux.

  319: 
  320: NEWS for rsync 3.0.5 (28 Dec 2008)
  321: Protocol: 30 (unchanged)
  322: Changes since 3.0.4:
  323: 
  324:   BUG FIXES:
  325: 
  326:     - Initialize xattr data in a couple spots in the hlink code, which avoids a
  327:       crash when the xattr pointer's memory happens to start out non-zero.
  328:       Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
  329: 
  330:     - Don't send a bogus "-" option to an older server if there were no short
  331:       options specified.
  332: 
  333:     - Fixed skipping of unneeded updates in a batch file when incremental
  334:       recursion is active.  Added a test for this.  Made batch-mode handle
  335:       "redo" files properly (and without hanging).
  336: 
  337:     - Fix the %P logfile escape when the daemon logs from inside a chroot.
  338: 
  339:     - Fixed the use of -s (--protect-args) when used with a remote source or
  340:       destination that had an empty path (e.g. "host:").  Also fixed a problem
  341:       when -s was used when accessing a daemon via a remote-shell.
  342: 
  343:     - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from
  344:       file when the root of the transfer isn't the current directory.
  345: 
  346:     - Fixed a bug with "-K --delete" removing symlinks to directories when
  347:       incremental recursion is active.
  348: 
  349:     - Fixed a hard to trigger hang when using --remove-source-files.
  350: 
  351:     - Got rid of an annoying delay when accessing a daemon via a remote-shell.
  352: 
  353:     - Properly ignore (superfluous) source args on a --read-batch command.
  354: 
  355:     - Improved the manpage's description of the '*' wildcard to remove the
  356:       confusing "non-empty" qualifier.
  357: 
  358:     - Fixed reverse lookups in the compatibility-library version of
  359:       getnameinfo().
  360: 
  361:     - Fixed a bug when using --sparse on a sparse file that has over 2GB of
  362:       consecutive sparse data.
  363: 
  364:     - Avoid a hang when using at least 3 --verbose options on a transfer with a
  365:       client sender (which includes local copying).
  366: 
  367:     - Fixed a problem with --delete-delay reporting an error when it was ready
  368:       to remove a directory that was now gone.
  369: 
  370:     - Got rid of a bunch of "warn_unused_result" compiler warnings.
  371: 
  372:     - If an ftruncate() on a received file fails, it now causes a partial-
  373:       transfer warning.
  374: 
  375:     - Allow a path with a leading "//" to be preserved (CYGWIN only).
  376: 
  377:   ENHANCEMENTS:
  378: 
  379:     - Made the support/atomic-rsync script able to perform a fully atomic
  380:       update of the copied hierarchy when the destination is setup using a
  381:       particular symlink idiom.
  382: 
  383: 
  384: NEWS for rsync 3.0.4 (6 Sep 2008)
  385: Protocol: 30 (unchanged)
  386: Changes since 3.0.3:
  387: 
  388:   BUG FIXES:
  389: 
  390:     - Fixed a bug in the hard-linking code where it would sometimes try to
  391:       allocate 0 bytes of memory (which fails on some OSes, such as AIX).
  392: 
  393:     - Fixed the hard-linking of files from a device that has a device number
  394:       of 0 (which seems to be a common device number on NetBSD).
  395: 
  396:     - Fixed the handling of a --partial-dir that cannot be created.  This
  397:       particularly impacts the --delay-updates option (since the files cannot
  398:       be delayed without a partial-dir), and was potentially destructive if
  399:       the --remove-source-files was also specified.
  400: 
  401:     - Fixed a couple issues in the --fake-super handling of xattrs when the
  402:       destination files have root-level attributes (e.g. selinux values) that
  403:       a non-root copy can't affect.
  404: 
  405:     - Improved the keep-alive check in the generator to fire consistently in
  406:       incremental-recursion mode when --timeout is enabled.
  407: 
  408:     - The --iconv option now converts the content of a symlink too, instead
  409:       of leaving it in the wrong character-set (requires 3.0.4 on both sides
  410:       of the transfer).
  411: 
  412:     - When using --iconv, if a filename fails to convert on the receiving side,
  413:       this no longer makes deletions in the root-dir of the transfer fail
  414:       silently (the user now gets a warning about deletions being disabled
  415:       due to IO error as long as --ignore-errors was not specified).
  416: 
  417:     - When using --iconv, if a server-side receiver can't convert a filename,
  418:       the error message sent back to the client no longer mangles the name
  419:       with the wrong charset conversion.
  420: 
  421:     - Fixed a potential alignment issue in the IRIX ACL code when allocating
  422:       the initial "struct acl" object.  Also, cast mallocs to avoid warnings.
  423: 
  424:     - Changed some errors that were going to stdout to go to stderr.
  425: 
  426:     - Made human_num() and human_dnum() able to output a negative number
  427:       (rather than outputting a cryptic string of punctuation).
  428: 
  429:   ENHANCEMENTS:
  430: 
  431:     - Rsync will avoid sending an -e option to the server if an older protocol
  432:       is requested (and thus the option would not be useful).  This lets the
  433:       user specify the --protocol=29 option to access an overly-restrictive
  434:       server that is rejecting the protocol-30 use of -e to the server.
  435: 
  436:     - Improved the message output for an RERR_PARTIAL exit.
  437: 
  438:   DEVELOPER RELATED:
  439: 
  440:     - The Makefile will not halt for just a timestamp change on the Makefile
  441:       or the configure files, only for actual changes in content.
  442: 
  443:     - Changed some commands in the testsuite's xattrs.test that called "rsync"
  444:       instead of "$RSYNC".
  445: 
  446:     - Enhanced the release scripts to be able to handle a branch release and
  447:       to do even more consistency checks on the files.

  450: NEWS for rsync 3.0.3 (29 Jun 2008)
  451: Protocol: 30 (unchanged)
  452: Changes since 3.0.2:
  453: 
  454:   BUG FIXES:
  455: 
  456:     - Fixed a wildcard matching problem in the daemon when a module has
  457:       "use chroot" enabled.
  458: 
  459:     - Fixed a crash bug in the hard-link code.
  460: 
  461:     - Fixed the sending of xattr directory information when the code finds a
  462:       --link-dest or --copy-dest directory with unchanged xattrs -- the
  463:       destination directory now gets these unchanged xattrs properly applied.
  464: 
  465:     - Fixed an xattr-sending glitch that could cause an "Internal abbrev"
  466:       error.
  467: 
  468:     - Fixed the combination of --xattrs and --backup.
  469: 
  470:     - The generator no longer allows a '.' dir to be excluded by a daemon-
  471:       exclude rule.
  472: 
  473:     - Fixed deletion handling when copying a single, empty directory (with no
  474:       files) to a differently named, non-existent directory.
  475: 
  476:     - Fixed the conversion of spaces into dashes in the %M log escape.
  477: 
  478:     - Fixed several places in the code that were not returning the right
  479:       errno when a function failed.
  480: 
  481:     - Fixed the backing up of a device or special file into a backup dir.
  482: 
  483:     - Moved the setting of the socket options prior to the connect().
  484: 
  485:     - If rsync exits in the middle of a --progress output, it now outputs a
  486:       newline to help prevent the progress line from being overwritten.
  487: 
  488:     - Fixed a problem with how a destination path with a trailing slash or
  489:       a trailing dot-dir was compared against the daemon excludes.
  490: 
  491:     - Fixed the sending of large (size > 16GB) files when talking to an older
  492:       rsync (protocols < 30):  we now use a compatible block size limit.
  493: 
  494:     - If a file's length is so huge that we overflow a checksum buffer count
  495:       (i.e. several hundred TB), warn the user and avoid sending an invalid
  496:       checksum struct over the wire.
  497: 
  498:     - If a source arg is excluded, --relative no longer adds the excluded
  499:       arg's implied dirs to the transfer.  This fix also made the exclude
  500:       check happen in the better place in the sending code.
  501: 
  502:     - Use the overflow_exit() function for overflows, not out_of_memory().
  503: 
  504:     - Improved the code to better handle a system that has only 32-bit file
  505:       offsets.
  506: 
  507:   ENHANCEMENTS:
  508: 
  509:     - The rsyncd.conf manpage now consistently refers to the parameters in
  510:       the daemon config file as "parameters".
  511: 
  512:     - The description of the --inplace option was improved.
  513: 
  514:   EXTRAS:
  515: 
  516:     - Added a new script in the support directory, deny-rsync, which allows
  517:       an admin to (temporarily) replace the rsync command with a script that
  518:       sends an error message to the remote client via the rsync protocol.
  519: 
  520:   DEVELOPER RELATED:
  521: 
  522:     - Fixed a testcase failure if the tests are run as root and made some
  523:       compatibility improvements.
  524: 
  525:     - Improved the daemon tests, including checking module comments, the
  526:       listing of files, and the ensuring that daemon excludes can't affect
  527:       a dot-dir arg.
  528: 
  529:     - Improved some build rules for those that build in a separate directory
  530:       from the source, including better install rules for the man pages, and
  531:       the fixing of a proto.h-tstamp rule that could make the binaries get
  532:       rebuild without cause.
  533: 
  534:     - Improved the testsuite to work around a problem with some utilities
  535:       (e.g. cp -p & touch -r) rounding sub-second timestamps.
  536: 
  537:     - Ensure that the early patches don't cause any generated-file hunks to
  538:       bleed-over into patches that follow.

  545:   BUG FIXES:
  546:

  561: NEWS for rsync 3.0.1 (3 Apr 2008)
  562: Protocol: 30 (unchanged)
  563: Changes since 3.0.0:
  564: 
  565:   NOTABLE CHANGES IN BEHAVIOR:
  566: 
  567:     - Added the 'c'-flag to the itemizing of non-regular files so that the
  568:       itemized output doesn't get hidden if there were no attribute changes,
  569:       and also so that the itemizing of a --copy-links run will distinguish
  570:       between copying an identical non-regular file and the creation of a
  571:       revised version with a new value (e.g. a changed symlink referent, a
  572:       new device number, etc.).
  573: 
  574:   BUG FIXES:
  575: 
  576:     - Fixed a crash bug when a single-use rsync daemon (via remote shell) was
  577:       run without specifying a --config=FILE option.
  578: 
  579:     - Fixed a crash when backing up a directory that has a default ACL.
  580: 
  581:     - Fixed a bug in the handling of xattr values that could cause rsync to
  582:       not think that a file's extended attributes are up-to-date.
  583: 
  584:     - Fixed the working of --fake-super with --link-dest and --xattrs.
  585: 
  586:     - Fixed a hang when combining --dry-run with --remove-source-files.
  587: 
  588:     - Fixed a bug with --iconv's handling of files that cannot be converted:
  589:       a failed name can no longer cause a transfer failure.
  590: 
  591:     - Fixed the building of the rounding.h file on systems that need custom
  592:       CPPFLAGS to be used.  Also improved the error reporting if the building
  593:       of rounding.h fails.
  594: 
  595:     - Fixed the use of the --protect-args (-s) option when talking to a daemon.
  596: 
  597:     - Fixed the --ignore-existing option's protection of files on the receiver
  598:       that are non-regular files on the sender (e.g. if a symlink or a dir on
  599:       the sender is trying to replace a file on the receiver).  The reverse
  600:       protection (protecting a dir/symlink/device from being replaced by a
  601:       file) was already working.
  602: 
  603:     - Fixed an assert failure if --hard-links is combined with an option that
  604:       can skip a file in a set of hard-linked files (i.e. --ignore-existing,
  605:       --append, etc.), without skipping all the files in the set.
  606: 
  607:     - Avoid setting the modify time on a directory that already has the right
  608:       modify time set.  This avoids tweaking the dir's ctime.
  609: 
  610:     - Improved the daemon-exclude handling to do a better job of applying the
  611:       exclude rules to path entries.  It also sends the user an error just as
  612:       if the files were actually missing (instead of silently ignoring the
  613:       user's args), and avoids sending the user the filter-action messages
  614:       for these non-user-initiated rules.
  615: 
  616:     - Fixed some glitches with the dry-run code's missing-directory
  617:       handling, including a problem when combined with --fuzzy.
  618: 
  619:     - Fixed some glitches with the skipped-directory handling.
  620: 
  621:     - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
  622: 
  623:     - Fixed a glitch in the itemizing of permissions with the -E option.
  624: 
  625:     - The --append option's restricting of transfers to those that add data no
  626:       longer prevents the updating of non-content changes to otherwise up-to-
  627:       date files (i.e. those with the same content but differing permissions,
  628:       ownership, xattrs, etc.).
  629: 
  630:     - Don't allow --fake-super to be specified with -XX (double --xattrs)
  631:       because the options conflict.  If a daemon has "fake super" enabled,
  632:       it automatically downgrades a -XX request to -X.
  633: 
  634:     - Fixed a couple bugs in the parsing of daemon-config excludes that could
  635:       make a floating exclude rule get treated as matching an absolute path.
  636: 
  637:     - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
  638:       wasn't compiled in to the daemon (avoiding a warning in the logs).
  639: 
  640:     - Fixed the inclusion of per-dir merge files from implied dirs.
  641: 
  642:     - Fixed the support/rrsync script to work with the latest options that
  643:       rsync sends (including its flag-specifying use of -e to the server).
  644: 
  645:   ENHANCEMENTS:
  646: 
  647:     - Added the --old-dirs (--old-d) option to make it easier for a user to
  648:       ask for file-listings with older rsync versions (this is easier than
  649:       having to type "-r --exclude='/*/*'" manually).
  650: 
  651:     - When getting an error while asking an older rsync daemon for a file
  652:       listing, rsync will try to notice if the error is a rejection of the
  653:       --dirs (-d) option and let the user know how to work around the issue.
  654: 
  655:     - Added a few more --no-OPTION overrides.
  656: 
  657:     - Improved the documentation of the --append option.
  658: 
  659:     - Improved the documentation of the filter/exclude/include daemon
  660:       parameters.
  661: 
  662:   INTERNAL:
  663: 
  664:     - Fixed a couple minor bugs in the included popt library (ones which I
  665:       sent to the official popt project for inclusion in the 1.14 release).
  666: 
  667:     - Fixed a stat() call that should have been do_stat() so that the proper
  668:       normal/64-bit stat() function gets called.  (Was in an area that should
  669:       not have caused problems, though.)
  670: 
  671:     - Changed the file-glob code to do a directory scan without using the
  672:       "glob" and "glob.h".  This lets us do the globbing with less memory
  673:       churn, and also avoid adding daemon-excluded items to the returned
  674:       args.
  675: 
  676:   DEVELOPER RELATED:
  677: 
  678:     - The configure script tries to get the user's compiler to not warn about
  679:       unused function parameters if the build is not including one or more of
  680:       the ACL/xattrs/iconv features.
  681: 
  682:     - The configure script now has better checks for figuring out if the
  683:       included popt code should be used or not.
  684: 
  685:     - Fixed two testsuite glitches: avoid a failure if someone's "cd" command
  686:       outputs the current directory when cd-ing to a relative path, and made
  687:       the itemized test query how rsync was built to determine if it should
  688:       expect hard-linked symlinks or not.
  689: 
  690:     - Updated the testsuite to verify that various bug fixes remain fixed.
  691: 
  692:     - The RPM spec file was updated to have: (1) comments for how to use the
  693:       rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
  694: 
  695:     - Updated the build scripts to work with a revised FTP directory
  696:       structure.

  699: NEWS for rsync 3.0.0 (1 Mar 2008)
  700: Protocol: 30 (changed)
  701: Changes since 2.6.9:
  702: 
  703:   NOTABLE CHANGES IN BEHAVIOR:
  704: 
  705:     - The handling of implied directories when using --relative has changed to
  706:       send them as directories (e.g. no implied dir is ever sent as a symlink).
  707:       This avoids unexpected behavior and should not adversely affect most
  708:       people.  If you're one of those rare individuals who relied upon having
  709:       an implied dir be duplicated as a symlink, you should specify the
  710:       transfer of the symlink and the transfer of the referent directory as
  711:       separate args.  (See also --keep-dirlinks and --no-implied-dirs.)
  712:       Also, exclude rules no longer have a partial effect on implied dirs.
  713: 
  714:     - Requesting a remote file-listing without specifying -r (--recursive) now
  715:       sends the -d (--dirs) option to the remote rsync rather than sending -r
  716:       along with an extra exclude of /*/*.  If the remote rsync does not
  717:       understand the -d option (i.e. it is 2.6.3 or older), you will need to
  718:       either turn off -d (--no-d), or specify  -r --exclude='/*/*'  manually.
  719: 
  720:     - In --dry-run mode, the last line of the verbose summary text is output
  721:       with a "(DRY RUN)" suffix to help remind you that no updates were made.
  722:       Similarly, --only-write-batch outputs "(BATCH ONLY)".
  723: 
  724:     - A writable rsync daemon with "use chroot" disabled now defaults to a
  725:       symlink-munging behavior designed to make symlinks safer while also
  726:       allowing absolute symlinks to be stored and retrieved.  This also has
  727:       the effect of making symlinks unusable while they're in the daemon's
  728:       hierarchy.  See the daemon's "munge symlinks" parameter for details.
  729: 
  730:     - Starting up an extra copy of an rsync daemon will not clobber the pidfile
  731:       for the running daemon -- if the pidfile exists, the new daemon will exit
  732:       with an error.  This means that your wrapper script that starts the rsync
  733:       daemon should be made to handle lock-breaking (if you want any automatic
  734:       breaking of locks to be done).
  735: 
  736:   BUG FIXES:
  737: 
  738:     - A daemon with "use chroot = no" and excluded items listed in the daemon
  739:       config file now properly checks an absolute-path arg specified for these
  740:       options:  --compare-dest, --link-dest, --copy-dest, --partial-dir,
  741:       --backup-dir, --temp-dir, and --files-from.
  742: 
  743:     - A daemon can now be told to disable all user- and group-name translation
  744:       on a per-module basis.  This avoids a potential problem with a writable
  745:       daemon module that has "use chroot" enabled -- if precautions weren't
  746:       taken, a user could try to add a missing library and get rsync to use
  747:       it.  This makes rsync safer by default, and more configurable when id-
  748:       translation is not desired.  See the daemon's "numeric ids" parameter
  749:       for full details.
  750: 
  751:     - A chroot daemon can now indicate which part of its path should affect the
  752:       chroot call, and which part should become an inside-chroot path for the
  753:       module.  This allows you to have outside-the-transfer paths (such as for
  754:       libraries) even when you enable chroot protection.  The idiom used in the
  755:       rsyncd.conf file is:  path = /chroot/dirs/./dirs/inside
  756: 
  757:     - If a file's data arrived successfully on the receiving side but the
  758:       rename of the temporary file to the destination file failed AND the
  759:       --remove-source-files (or the deprecated --remove-sent-files) option
  760:       was specified, rsync no longer erroneously removes the associated
  761:       source file.
  762: 
  763:     - Fixed the output of -ii when combined with one of the --*-dest options:
  764:       it now itemizes all the items, not just the changed ones.
  765: 
  766:     - Made the output of all file types consistent when using a --*-dest
  767:       option.  Prior versions would output too many creation events for
  768:       matching items.
  769: 
  770:     - The code that waits for a child pid now handles being interrupted by a
  771:       signal.  This fixes a problem with the pre-xfer exec function not being
  772:       able to get the exit status from the script.
  773: 
  774:     - A negated filter rule (i.e. with a '!' modifier) no longer loses the
  775:       negation when sending the filter rules to the remote rsync.
  776: 
  777:     - Fixed a problem with the --out-format (aka --log-format) option %f:  it
  778:       no longer outputs superfluous directory info for a non-daemon rsync.
  779: 
  780:     - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
  781:       files (which includes local copies).  Version 2.6.9 would complete the
  782:       copy, but exit with an error when the receiver output its memory stats.
  783: 
  784:     - If --password-file is used on a non-daemon transfer, rsync now complains
  785:       and exits.  This should help users figure out that they can't use this
  786:       option to control a remote shell's password prompt.
  787: 
  788:     - Make sure that directory permissions of a newly-created destination
  789:       directory are handled right when --perms is left off.
  790: 
  791:     - The itemized output of a newly-created destination directory is now
  792:       output as a creation event, not a change event.
  793: 
  794:     - Improved --hard-link so that more corner cases are handled correctly
  795:       when combined with options such as --link-dest and/or --ignore-existing.
  796: 
  797:     - The --append option no longer updates a file that has the same size.
  798: 
  799:     - Fixed a bug when combining --backup and --backup-dir with --inplace:
  800:       any missing backup directories are now created.
  801: 
  802:     - Fixed a bug when using --backup and --inplace with --whole-file or
  803:       --read-batch: backup files are actually created now.
  804: 
  805:     - The daemon pidfile is checked and created sooner in the startup sequence.
  806: 
  807:     - If a daemon module's "path" value is not an absolute pathname, the code
  808:       now makes it absolute internally (making it work properly).
  809: 
  810:     - Ensure that a temporary file always has owner-write permission while we
  811:       are writing to it.  This avoids problems with some network filesystems
  812:       when transfering read-only files.
  813: 
  814:     - Any errors output about password-file reading no longer cause an error at
  815:       the end of the run about a partial transfer.
  816: 
  817:     - The --read-batch option for protocol 30 now ensures that several more
  818:       options are set correctly for the current batch file:  --iconv, --acls,
  819:       --xattrs, --inplace, --append, and --append-verify.
  820: 
  821:     - Using --only-write-batch to a daemon receiver now works properly (older
  822:       versions would update some files while writing the batch).
  823: 
  824:     - Avoid outputting a "file has vanished" message when the file is a broken
  825:       symlink and --copy-unsafe-links or --copy-dirlinks is used (the code
  826:       already handled this for --copy-links).
  827: 
  828:     - Fixed the combination of --only-write-batch and --dry-run.
  829: 
  830:     - Fixed rsync's ability to remove files that are not writable by the file's
  831:       owner when rsync is running as the same user.
  832: 
  833:     - When transferring large files, the sender's hashtable of checksums is
  834:       kept at a more reasonable state of fullness (no more than 80% full) so
  835:       that the scanning of the hashtable will not bog down as the number of
  836:       blocks increases.
  837: 
  838:   ENHANCEMENTS:
  839: 
  840:     - A new incremental-recursion algorithm is now used when rsync is talking
  841:       to another 3.x version.  This starts the transfer going more quickly
  842:       (before all the files have been found), and requires much less memory.
  843:       See the --recursive option in the manpage for some restrictions.
  844: 
  845:     - Lowered memory use in the non-incremental-recursion algorithm for typical
  846:       option values (usually saving from 21-29 bytes per file).
  847: 
  848:     - The default --delete algorithm is now --delete-during when talking to a
  849:       3.x rsync.  This is a faster scan than using --delete-before (which is
  850:       the default when talking to older rsync versions), and is compatible with
  851:       the new incremental recursion mode.
  852: 
  853:     - Rsync now allows multiple remote-source args to be specified rather than
  854:       having to rely on a special space-splitting side-effect of the remote-
  855:       shell.  Additional remote args must specify the same host or an empty one
  856:       (e.g. empty:  :file1  or  ::module/file2).  For example, this means that
  857:       local use of brace expansion now works:  rsync -av host:dir/{f1,f2} .
  858: 
  859:     - Added the --protect-args (-s) option, that tells rsync to send most of
  860:       the command-line args at the start of the transfer rather than as args
  861:       to the remote-shell command.  This protects them from space-splitting,
  862:       and only interprets basic wildcard special shell characters (*?[).
  863: 
  864:     - Added the --delete-delay option, which is a more efficient way to delete
  865:       files at the end of the transfer without needing a separate delete pass.
  866: 
  867:     - Added the --acls (-A) option to preserve Access Control Lists.  This is
  868:       an improved version of the prior patch that was available, and it even
  869:       supports OS X ACLs.  If you need to have backward compatibility with old,
  870:       ACL-patched versions of rsync, apply the acls.diff file from the patches
  871:       dir.
  872: 
  873:     - Added the --xattrs (-X) option to preserve extended attributes.  This is
  874:       an improved version of the prior patch that was available, and it even
  875:       supports OS X xattrs (which includes their resource fork data).  If you
  876:       need to have backward compatibility with old, xattr-patched versions of
  877:       rsync, apply the xattrs.diff file from the patches dir.
  878: 
  879:     - Added the --fake-super option that allows a non-super user to preserve
  880:       all attributes of a file by using a special extended-attribute idiom.
  881:       It even supports the storing of foreign ACL data on your backup server.
  882:       There is also an analogous "fake super" parameter for an rsync daemon.
  883: 
  884:     - Added the --iconv option, which allows rsync to convert filenames from
  885:       one character-set to another during the transfer.  The default is to
  886:       make this feature available as long as your system has iconv_open().
  887:       If compilation fails, specify --disable-iconv to configure, and then
  888:       rebuild.  If you want rsync to perform character-set conversions by
  889:       default, you can specify --enable-iconv=CONVERT_STRING with the default
  890:       value for the --iconv option that you wish to use.  For example,
  891:       "--enable-iconv=." is a good choice.  See the rsync manpage for an
  892:       explanation of the --iconv option's settings.
  893: 
  894:     - A new daemon config parameter, "charset", lets you control the character-
  895:       set that is used during an --iconv transfer to/from a daemon module.  You
  896:       can also set your daemon to refuse "no-iconv" if you want to force the
  897:       client to use an --iconv transfer (requiring an rsync 3.x client).
  898: 
  899:     - Added the --skip-compress=LIST option to override the default list of
  900:       file suffixes that will not be compressed when using --compress (-z).
  901: 
  902:     - The daemon's default for "dont compress" was extended to include:
  903: 	  *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
  904:       The name-matching routine was also optimized to run more quickly.
  905: 
  906:     - The --max-delete option now outputs a warning if it skipped any file
  907:       deletions, including a count of how many deletions were skipped.  (Older
  908:       versions just silently stopped deleting things.)
  909: 
  910:     - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
  911:       about extraneous files without deleting anything.  If you're not sure
  912:       what version the client is, you can use the less-obvious --max-delete=-1,
  913:       as both old and new versions will treat that as the same request (though
  914:       older versions don't warn).
  915: 
  916:     - The --hard-link option now uses less memory on both the sending and
  917:       receiving side for all protocol versions.  For protocol 30, the use of a
  918:       hashtable on the sending side allows us to more efficiently convey to the
  919:       receiver what files are linked together.  This reduces the amount of data
  920:       sent over the socket by a considerable margin (rather than adding more
  921:       data), and limits the in-memory storage of the device+inode information
  922:       to just the sending side for the new protocol 30, or to the receiving
  923:       side when speaking an older protocol (note that older rsync versions kept
  924:       the device+inode information on both sides).
  925: 
  926:     - The filter rules now support a perishable ("p") modifier that marks rules
  927:       that should not have an effect in a directory that is being deleted.  e.g.
  928:       -f '-p .svn/' would only affect "live" .svn directories.
  929: 
  930:     - Rsync checks all the alternate-destination args for validity (e.g.
  931:       --link-dest).  This lets the user know when they specified a directory
  932:       that does not exist.
  933: 
  934:     - If we get an ENOSYS error setting the time on a symlink, we don't
  935:       complain about it anymore (for those systems that even support the
  936:       setting of the modify-time on a symlink).
  937: 
  938:     - Protocol 30 now uses MD5 checksums instead of MD4.
  939: 
  940:     - Changed the --append option to not checksum the existing data in the
  941:       destination file, which speeds up file appending.
  942: 
  943:     - Added the --append-verify option, which works like the older --append
  944:       option (verifying the existing data in the destination file).  For
  945:       compatibility with older rsync versions, any use of --append that is
  946:       talking protocol 29 or older will revert to the --append-verify method.
  947: 
  948:     - Added the --contimeout=SECONDS option that lets the user specify a
  949:       connection timeout for rsync daemon access.
  950: 
  951:     - Documented and extended the support for the RSYNC_CONNECT_PROG variable
  952:       that can be used to enhance the client side of a daemon connection.
  953: 
  954:     - Improved the dashes and double-quotes in the nroff manpage output.
  955: 
  956:     - Rsync now supports a lot more --no-OPTION override options.
  957: 
  958:   INTERNAL:
  959: 
  960:     - The file-list sorting algorithm now uses a sort that keeps any same-
  961:       named items in the same order as they were specified.  This allows
  962:       rsync to always ensure that the first of the duplicates is the one
  963:       that will be included in the copy.  The new sort is also faster
  964:       than the glibc version of qsort() and mergesort().
  965: 
  966:     - Rsync now supports the transfer of 64-bit timestamps (time_t values).
  967: 
  968:     - Made the file-deletion code use a little less stack when recursing
  969:       through a directory hierarchy of extraneous files.
  970: 
  971:     - Fixed a build problem with older (2.x) versions of gcc.
  972: 
  973:     - Added some isType() functions that make dealing with signed characters
  974:       easier without forcing variables via casts.
  975: 
  976:     - Changed strcat/strcpy/sprintf function calls to use safer versions.
  977: 
  978:     - Upgraded the included popt version to 1.10.2 and improved its use of
  979:       string-handling functions.
  980: 
  981:     - Added missing prototypes for compatibility functions from the lib dir.
  982: 
  983:     - Configure determines if iconv() has a const arg, allowing us to avoid a
  984:       compiler warning.
  985: 
  986:     - Made the sending of some numbers more efficient for protocol 30.
  987: 
  988:     - Make sure that a daemon process doesn't mind if the client was weird and
  989:       omitted the --server option.
  990: 
  991:     - There are more internal logging categories available in protocol 30 than
  992:       the age-old FINFO and FERROR, including FERROR_XFER and FWARN.  These new
  993:       categories allow some errors and warnings to go to stderr without causing
  994:       an erroneous end-of-run warning about some files not being able to be
  995:       transferred.
  996: 
  997:     - Improved the use of "const" on pointers.
  998: 
  999:     - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
 1000:       older sections of a pool's memory.
 1001: 
 1002:     - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
 1003:       some new code (derived from samba, derived from PostgreSQL) that has a
 1004:       better license than the old code.
 1005: 
 1006:   DEVELOPER RELATED:
 1007: 
 1008:     - Rsync is now licensed under the GPLv3 or later.
 1009: 
 1010:     - Rsync is now being maintained in a "git" repository instead of CVS
 1011:       (though the old CVS repository still exists for historical access).
 1012:       Several maintenance scripts were updated to work with git.
 1013: 
 1014:     - Generated files are no longer committed into the source repository.  The
 1015:       autoconf and autoheader commands are now automatically run during the
 1016:       normal use of "configure" and "make".  The latest dev versions of all
 1017:       generated files can also be copied from the samba.org web site (see the
 1018:       prepare-source script's fetch option).
 1019: 
 1020:     - The "patches" directory of diff files is now built from branches in the
 1021:       rsync git repository (branch patch/FOO creates file patches/FOO.diff).
 1022:       This directory is now distributed in a separate separate tar file named
 1023:       rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
 1024: 
 1025:     - The proto.h file is now built using a simple perl script rather than a
 1026:       complex awk script, which proved to be more widely compatible.
 1027: 
 1028:     - When running the tests, we now put our per-test temp dirs into a sub-
 1029:       directory named testtmp (which is created, if missing).  This allows
 1030:       someone to symlink the testtmp directory to another filesystem (which is
 1031:       useful if the build dir's filesystem does not support ACLs and xattrs,
 1032:       but another filesystem does).
 1033: 
 1034:     - Rsync now has a way of handling protocol-version changes during the
 1035:       development of a new protocol version.  This causes any out-of-sync
 1036:       versions to speak an older protocol rather than fail in a cryptic manner.
 1037:       This addition makes it safer to deploy a pre-release version that may
 1038:       interact with the public.  This new exchange of sub-version info does not
 1039:       interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
 1040:       does not have enough range to allow the main protocol number to be
 1041:       incremented for every minor tweak in that happens during development).
 1042: 
 1043:     - The csprotocol.txt file was updated to mention the daemon protocol change
 1044:       in the 3.0.0 release.
 1045: 
 1046: 
 1047: NEWS for rsync 2.6.9 (6 Nov 2006)
 1048: Protocol: 29 (unchanged)
 1049: Changes since 2.6.8:
 1050: 
 1051:   BUG FIXES:
 1052: 
 1053:     - If rsync is interrupted via a handled signal (such as SIGINT), it will
 1054:       once again clean-up its temp file from the destination dir.
 1055: 
 1056:     - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
 1057:       --copy-dest, and --compare-dest options to a daemon without chroot: if
 1058:       the copy's destination dir is deeper than the top of the module's path,
 1059:       these options now accept a safe number of parent-dir (../) references
 1060:       (since these options are relative to the destination dir).  The old code
 1061:       incorrectly chopped off all "../" prefixes for these options, no matter
 1062:       how deep the destination directory was in the module's hierarchy.
 1063: 
 1064:     - Fixed a bug where a deferred info/error/log message could get sent
 1065:       directly to the sender instead of being handled by rwrite() in the
 1066:       generator.  This fixes an "unexpected tag 3" fatal error, and should
 1067:       also fix a potential problem where a deferred info/error message from
 1068:       the receiver might bypass the log file and get sent only to the client
 1069:       process.  (These problems could only affect an rsync daemon that was
 1070:       receiving files.)
 1071: 
 1072:     - Fixed a bug when --inplace was combined with a --*-dest option and we
 1073:       update a file's data using an alternate basis file.  The code now
 1074:       notices that it needs to copy the matching data from the basis file
 1075:       instead of (wrongly) assuming that it was already present in the file.
 1076: 
 1077:     - Fixed a bug where using --dry-run with a --*-dest option with a path
 1078:       relative to a directory that does not yet exist:  the affected option
 1079:       gets its proper path value so that the output of the dry-run is right.
 1080: 
 1081:     - Fixed a bug in the %f logfile escape when receiving files: the
 1082:       destination path is now included in the output (e.g. you can now tell
 1083:       when a user specifies a subdir inside a module).
 1084: 
 1085:     - If the receiving side fails to create a directory, it will now skip
 1086:       trying to update everything that is inside that directory.
 1087: 
 1088:     - If --link-dest is specified with --checksum but without --times, rsync
 1089:       will now allow a hard-link to be created to a matching link-dest file
 1090:       even when the file's modify-time doesn't match the server's file.
 1091: 
 1092:     - The daemon now calls more timezone-using functions prior to doing a
 1093:       chroot.  This should help some C libraries to generate proper timestamps
 1094:       from inside a chrooted daemon (and to not try to access /etc/timezone
 1095:       over and over again).
 1096: 
 1097:     - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
 1098:       it now deletes an alternate basis file from the partial-dir that was used
 1099:       to successfully update a destination file.
 1100: 
 1101:     - Fixed a bug in the handling of --delete-excluded when using a per-dir
 1102:       merge file:  the merge file is now honored on the receiving side, and
 1103:       only its unqualified include/exclude commands are ignored (just as is
 1104:       done for global include/excludes).
 1105: 
 1106:     - Fixed a recent bug where --delete was not working when transferring from
 1107:       the root (/) of the filesystem with --relative enabled.
 1108: 
 1109:     - Fixed a recent bug where an --exclude='*' could affect the root (/) of
 1110:       the filesystem with --relative enabled.
 1111: 
 1112:     - When --inplace creates a file, it is now created with owner read/write
 1113:       permissions (0600) instead of no permissions at all.  This avoids a
 1114:       problem continuing a transfer that was interrupted (since --inplace
 1115:       will not update a file that has no write permissions).
 1116: 
 1117:     - If either --remove-source-files or --remove-sent-files is enabled and we
 1118:       are unable to remove the source file, rsync now outputs an error.
 1119: 
 1120:     - Fixed a bug in the daemon's "incoming chmod" rule:  newly-created
 1121:       directories no longer get the 'F' (file) rules applied to them.
 1122: 
 1123:     - Fixed an infinite loop bug when a filter rule was rejected due to being
 1124:       overly long.
 1125: 
 1126:     - When the server receives a --partial-dir option from the client, it no
 1127:       longer runs the client-side code that adds an assumed filter rule (since
 1128:       the client will be sending us the rules in the usual manner, and they
 1129:       may have chosen to override the auto-added rule).
 1130: 
 1131:   ENHANCEMENTS:
 1132: 
 1133:     - Added the --log-file=FILE and --log-file-format=FORMAT options.  These
 1134:       can be used to tell any rsync to output what it is doing to a log file.
 1135:       They work with a client rsync, a non-daemon server rsync (see the man
 1136:       page for instructions), and also allows the overriding of rsyncd.conf
 1137:       settings when starting a daemon.
 1138: 
 1139:     - The --log-format option was renamed to be --out-format to avoid confusing
 1140:       it with affecting the log-file output.  (The old option remains as an
 1141:       alias for the new to preserve backward compatibility.)
 1142: 
 1143:     - Made "log file" and "syslog facility" settable on a per-module basis in
 1144:       the daemon's config file.
 1145: 
 1146:     - Added the --remove-source-files option as a replacement for the (now
 1147:       deprecated) --remove-sent-files option.  This new option removes all
 1148:       non-dirs from the source directories, even if the file was already
 1149:       up-to-date.  This fixes a problem where interrupting an rsync that
 1150:       was using --remove-sent-files and restarting it could leave behind
 1151:       a file that the earlier rsync synchronized, but didn't get to remove.
 1152:       (The deprecated --remove-sent-files is still understood for now, and
 1153:       still behaves in the same way as before.)
 1154: 
 1155:     - Added the option --no-motd to suppress the message-of-the-day output
 1156:       from a daemon when doing a copy.  (See the manpage for a caveat.)
 1157: 
 1158:     - Added a new environment variable to the pre-/post-xfer exec commands (in
 1159:       the daemon's config file):  RSYNC_PID.  This value will be the same in
 1160:       both the pre- and post-xfer commands, so it can be used as a unique ID
 1161:       if the pre-xfer command wants to cache some arg/request info for the
 1162:       post-xfer command.
 1163: 
 1164:   INTERNAL:
 1165: 
 1166:     - Did a code audit using IBM's code-checker program and made several
 1167:       changes, including: replacing most of the strcpy() and sprintf()
 1168:       calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
 1169:       an enum that had been intermingling a literal 0 with the defined enum
 1170:       values, silencing some uninitialized memory checks, marking some
 1171:       functions with a "noreturn" attribute, and changing an "if" that
 1172:       could never succeed on some platforms into a pre-processor directive
 1173:       that conditionally compiles the code.
 1174: 
 1175:     - Fixed a potential bug in f_name_cmp() when both the args are a
 1176:       top-level "." dir (which doesn't happen in normal operations).
 1177: 
 1178:     - Changed exit_cleanup() so that it can never return instead of exit.
 1179:       The old code might return if it found the exit_cleanup() function
 1180:       was being called recursively.  The new code is segmented so that
 1181:       any recursive calls move on to the next step of the exit-processing.
 1182: 
 1183:     - The macro WIFEXITED(stat) will now be defined if the OS didn't already
 1184:       define it.
 1185: 
 1186:   DEVELOPER RELATED:
 1187: 
 1188:     - The acls.diff and xattrs.diff patches have received a bunch of work to
 1189:       make them much closer to being acceptable in the main distribution.
 1190:       The xattrs patch also has some preliminary Mac OS X and FreeBSD
 1191:       compatibility code that various system types to exchange extended
 1192:       file-attributes.
 1193: 
 1194:     - A new diff in the patches dir, fake-root.diff, allows rsync to
 1195:       maintain a backup hierarchy with full owner, group, and device info
 1196:       without actually running as root.  It does this using a special
 1197:       extended attribute, so it depends on xattrs.diff (which depends on
 1198:       acls.diff).
 1199: 
 1200:     - The rsync.yo and rsyncd.conf.yo files have been updated to work
 1201:       better with the latest yodl 2.x releases.
 1202: 
 1203:     - Updated config.guess and config.sub to their 2006-07-02 versions.
 1204: 
 1205:     - Updated various files to include the latest FSF address and to have
 1206:       consistent opening comments.

 1209: NEWS for rsync 2.6.8 (22 Apr 2006)
 1210: Protocol: 29 (unchanged)
 1211: Changes since 2.6.7:
 1212: 
 1213:   BUG FIXES:
 1214: 
 1215:     - Fixed a bug in the exclude code where an anchored exclude without any
 1216:       wildcards fails to match an absolute source arg, but only when --relative
 1217:       is in effect.
 1218: 
 1219:     - Improved the I/O code for the generator to fix a potential hang when the
 1220:       receiver gets an EOF on the socket but the generator's select() call
 1221:       never indicates that the socket is writable for it to be notified about
 1222:       the EOF.  (This can happen when using stunnel).
 1223: 
 1224:     - Fixed a problem with the file-reading code where a failed read (such as
 1225:       that caused by a bad sector) would not advance the file's read-position
 1226:       beyond the failed read's data.
 1227: 
 1228:     - Fixed a logging bug where the "log file" directive was not being honored
 1229:       in a single-use daemon (one spawned by a remote-shell connection or by
 1230:       init).
 1231: 
 1232:     - If rsync cannot honor the --delete option, we output an error and exit
 1233:       instead of silently ignoring the option.
 1234: 
 1235:     - Fixed a bug in the --link-dest code that prevented special files (such as
 1236:       fifos) from being linked.
 1237: 
 1238:     - The ability to hard-link symlinks and special files is now determined at
 1239:       configure time instead of at runtime.  This fixes a bug with --link-dest
 1240:       creating a hard-link to a symlink's referent on a BSD system.
 1241: 
 1242:   ENHANCEMENTS:
 1243: 
 1244:     - In daemon mode, if rsync fails to bind to the requested port, the
 1245:       error(s) returned by socket() and/or bind() are now logged.
 1246: 
 1247:     - When we output a fatal error, we now output the version of rsync in the
 1248:       message.
 1249: 
 1250:     - Improved the documentation for the --owner and --group options.
 1251: 
 1252:     - The rsyncstats script in "support" has an improved line-parsing regex
 1253:       that is easier to read and also makes it to parse syslog-generated lines.
 1254: 
 1255:     - A new script in "support": file-attr-restore, can be used to restore the
 1256:       attributes of a file-set (the permissions, ownership, and group info)
 1257:       taken from the cached output of a "find ARG... -ls" command.
 1258: 
 1259:   DEVELOPER RELATED:
 1260: 
 1261:     - Removed the unused function write_int_named(), the unused variable
 1262:       io_read_phase, and the rarely used variable io_write_phase.  This also
 1263:       elides the confusing 'phase "unknown"' part of one error message.
 1264: 
 1265:     - Removed two unused configure checks and two related (also unused)
 1266:       compatibility functions.
 1267: 
 1268:     - The xattrs.diff patch received a security fix that prevents a potential
 1269:       buffer overflow in the receive_xattr() code.
 1270: 
 1271:     - The acls.diff patch has been improved quite a bit, with more to come.
 1272: 
 1273:     - A new patch was added: log-file.diff.  This contains an early version of
 1274:       a future option, --log-file=FILE, that will allow any rsync to log its
 1275:       actions to a file (something that only a daemon supports at present).
 1276: 
 1277: 
 1278: NEWS for rsync 2.6.7 (11 Mar 2006)
 1279: Protocol: 29 (unchanged)
 1280: Changes since 2.6.6:
 1281: 
 1282:   OUTPUT CHANGES:
 1283: 
 1284:     - The letter 'D' in the itemized output was being used for both devices
 1285:       (character or block) as well as other special files (such as fifos and
 1286:       named sockets).  This has changed to separate non-device special files
 1287:       under the 'S' designation (e.g. "cS+++++++ path/fifo").  See also the
 1288:       "--specials" option, below.
 1289: 
 1290:     - The way rsync escapes unreadable characters has changed.  First, rsync
 1291:       now has support for recognizing valid multibyte character sequences in
 1292:       your current locale, allowing it to escape fewer characters than before
 1293:       for a locale such as UTF-8.  Second, it now uses an escape idiom of
 1294:       "\#123", which is the literal string "\#" followed by exactly 3 octal
 1295:       digits.  Rsync no longer doubles a backslash character in a filename
 1296:       (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
 1297:       escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
 1298:       (e.g. it will output "foo\#134#789" when copying "foo\#789").  See also
 1299:       the --8-bit-output (-8) option, mentioned below.
 1300: 
 1301:       Script writers: the local rsync is the one that outputs escaped names,
 1302:       so if you need to support unescaping of filenames for older rsyncs, I'd
 1303:       suggest that you parse the output of "rsync --version" and only use the
 1304:       old unescaping rules for 2.6.5 and 2.6.6.
 1305: 
 1306:   BUG FIXES:
 1307: 
 1308:     - Fixed a really old bug that caused --checksum (-c) to checksum all the
 1309:       files encountered during the delete scan (ouch).
 1310: 
 1311:     - Fixed a potential hang in a remote generator:  when the receiver gets a
 1312:       read-error on the socket, it now signals the generator about this so that
 1313:       the generator does not try to send any of the terminating error messages
 1314:       to the client (avoiding a potential hang in some setups).
 1315: 
 1316:     - Made hard-links work with symlinks and devices again.
 1317: 
 1318:     - If the sender gets an early EOF reading a source file, we propagate this
 1319:       error to the receiver so that it can discard the file and try requesting
 1320:       it again (which is the existing behavior for other kinds of read errors).
 1321: 
 1322:     - If a device-file/special-file changes permissions, rsync now updates the
 1323:       permissions without recreating the file.
 1324: 
 1325:     - If the user specifies a remote-host for both the source and destination,
 1326:       we now output a syntax error rather than trying to open the destination
 1327:       hostspec as a filename.
 1328: 
 1329:     - When --inplace creates a new destination file, rsync now creates it with
 1330:       permissions 0600 instead of 0000 -- this makes restarting possible when
 1331:       the transfer gets interrupted in the middle of sending a new file.
 1332: 
 1333:     - Reject the combination of --inplace and --sparse since the sparse-output
 1334:       algorithm doesn't work when overwriting existing data.
 1335: 
 1336:     - Fixed the directory name in the error that is output when pop_dir()
 1337:       fails.
 1338: 
 1339:     - Really fixed the parsing of a "!" entry in .cvsignore files this time.
 1340: 
 1341:     - If the generator gets a stat() error on a file, output it (this used to
 1342:       require at least -vv for the error to be seen).
 1343: 
 1344:     - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
 1345:       the exit status properly and generate a better error.
 1346: 
 1347:     - Fixed some glitches in the double-verbose output when using --copy-dest,
 1348:       --link-dest, or --compare-dest.  Also improved how the verbose output
 1349:       handles hard-links (within the transfer) that had an up-to-date alternate
 1350:       "dest" file, and copied files (via --copy-dest).
 1351: 
 1352:     - Fixed the matching of the dont-compress items (e.g. *.gz) against files
 1353:       that have a path component containing a slash.
 1354: 
 1355:     - If the code reading a filter/exclude file gets an EINTR error, rsync now
 1356:       clears the error flag on the file handle so it can keep on reading.
 1357: 
 1358:     - If --relative is active, the sending side cleans up trailing "/" or "/."
 1359:       suffixes to avoid triggering a bug in older rsync versions.  Also, we now
 1360:       reject a ".." dir if it would be sent as a relative dir.
 1361: 
 1362:     - If a non-directory is in the way of a directory and rsync is run with
 1363:       --dry-run and --delete, rsync no longer complains about not being able
 1364:       to opendir() the not-yet present directory.
 1365: 
 1366:     - When --list-only is used and a non-existent local destination dir was
 1367:       also specified as a destination, rsync no longer generates a warning
 1368:       about being unable to create the missing directory.
 1369: 
 1370:     - Fixed some problems with --relative --no-implied-dirs when the
 1371:       destination directory did not yet exist:  we can now create a symlink or
 1372:       device when it is the first thing in the missing dir, and --fuzzy no
 1373:       longer complains about being unable to open the missing dir.
 1374: 
 1375:     - Fixed a bug where the --copy-links option would not affect implied
 1376:       directories without --copy-unsafe-links (see --relative).
 1377: 
 1378:     - Got rid of the need for --force to be used in some circumstances with
 1379:       --delete-after (making it consistent with --delete-before/-during).
 1380: 
 1381:     - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
 1382:       when a file is too large (rsync handles the write error).
 1383: 
 1384:     - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
 1385:       was not properly padded with trailing '=' chars.  This only affects a
 1386:       user that need to use a password-authenticated proxy for an outgoing
 1387:       daemon-rsync connection.
 1388: 
 1389:     - If we're transferring an empty directory to a new name, rsync no longer
 1390:       forces S_IWUSR if it wasn't already set, nor does it accidentally leave
 1391:       it set.
 1392: 
 1393:     - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
 1394:       checksum for the current file offset.
 1395: 
 1396:     - Rsync no longer allows a single directory to be copied over a non-
 1397:       directory destination arg.
 1398: 
 1399:   ENHANCEMENTS:
 1400: 
 1401:     - Added the --append option that makes rsync append data onto files that
 1402:       are longer on the source than the destination (this includes new files).
 1403: 
 1404:     - Added the --min-size=SIZE option to exclude small files from the
 1405:       transfer.
 1406: 
 1407:     - Added the --compress-level option to allow you to set how aggressive
 1408:       rsync's compression should be (this option implies --compress).
 1409: 
 1410:     - Enhanced the parsing of the SIZE value for --min-size and --max-size to
 1411:       allow easy entry of multiples of 1000 (instead of just multiples of 1024)
 1412:       and off-by-one values too (e.g. --max-size=8mb-1).
 1413: 
 1414:     - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
 1415:       high-bit characters that it thinks are unreadable in the current locale.
 1416: 
 1417:     - The new option --human-readable (-h) changes the output of --progress,
 1418:       --stats, and the end-of-run summary to be easier to read.  If repeated,
 1419:       the units become powers of 1024 instead of powers of 1000.  (The old
 1420:       meaning of -h, as a shorthand for --help, still works as long as you
 1421:       just use it on its own, as in "rsync -h".)
 1422: 
 1423:     - If lutimes() and/or lchmod() are around, use them to allow the
 1424:       preservation of attributes on symlinks.
 1425: 
 1426:     - The --link-dest option now affects symlinks and devices (when possible).
 1427: 
 1428:     - Added two config items to the rsyncd.conf parsing:  "pre-xfer exec" and
 1429:       "post-xfer exec".  These allow a command to be specified on a per-module
 1430:       basis that will be run before and/or after a daemon-mode transfer.  (See
 1431:       the man page for a list of the environment variables that are set with
 1432:       information about the transfer.)
 1433: 
 1434:     - When using the --relative option, you can now insert a dot dir in
 1435:       the source path to indicate where the replication of the source dirs
 1436:       should start.  For example, if you specify a source path of
 1437:       rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
 1438:       replicate the "baz/dir" part of the source path (note: a trailing
 1439:       dot dir is unaffected unless it also has a trailing slash).
 1440: 
 1441:     - Added some new --no-FOO options that make it easier to override unwanted
 1442:       implied or default options.  For example, "-a --no-o" (aka "--archive
 1443:       --no-owner") can be used to turn off the preservation of file ownership
 1444:       that is implied by -a.
 1445: 
 1446:     - Added the --chmod=MODE option that allows the destination permissions to
 1447:       be changed from the source permissions.  E.g. --chmod=g+w,o-rwx
 1448: 
 1449:     - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
 1450:       a module to specify what permissions changes should be applied to all
 1451:       files copied to and from the daemon.
 1452: 
 1453:     - Allow the --temp-dir option to be specified when starting a daemon, which
 1454:       sets the default temporary directory for incoming files.
 1455: 
 1456:     - If --delete is combined with --dirs without --recursive, rsync will now
 1457:       delete in any directory whose content is being synchronized.
 1458: 
 1459:     - If --backup is combined with --delete without --backup-dir (and without
 1460:       --delete-excluded), we add a "protect" filter-rule to ensure that files
 1461:       with the backup suffix are not deleted.
 1462: 
 1463:     - The file-count stats that are output by --progress were improved to
 1464:       better indicate what the numbers mean.  For instance, the output:
 1465:       "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
 1466:       to be transferred, and we still need to check 8383 more files out of
 1467:       a total of 9999.
 1468: 
 1469:     - The include/exclude code now allows a dir/*** directive (with 3 trailing
 1470:       stars) to match both the dir itself as well as all the content below the
 1471:       dir (dir/** would not match the dir).
 1472: 
 1473:     - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
 1474:       discard empty chains of directories from the file-list.  This makes it
 1475:       easier to selectively copy files from a source hierarchy and end up with
 1476:       just the directories needed to hold the resulting files.
 1477: 
 1478:     - If the --itemize-changes (-i) option is repeated, rsync now includes
 1479:       unchanged files in the itemized output (similar to -vv, but without all
 1480:       the other verbose messages that can get in the way).  Of course, the
 1481:       client must be version 2.6.7 for this to work, but the remote rsync only
 1482:       needs to be 2.6.7 if you're pushing files.
 1483: 
 1484:     - Added the --specials option to tell rsync to copy non-device special
 1485:       files (which rsync now attempts even as a normal user).  The --devices
 1486:       option now requests the copying of just devices (character and block).
 1487:       The -D option still requests both (e.g. --devices and --specials), -a
 1488:       still implies -D, and non-root users still get a silent downgrade that
 1489:       omits device copying.
 1490: 
 1491:     - Added the --super option to make the receiver always attempt super-user
 1492:       activities.  This is useful for systems that allow things such as devices
 1493:       to be created or ownership to be set without being UID 0, and is also
 1494:       useful for someone who wants to ensure that errors will be output if the
 1495:       receiving rsync isn't being run as root.
 1496: 
 1497:     - Added the --sockopts option for those few who want to customize the TCP
 1498:       options used to contact a daemon rsync.
 1499: 
 1500:     - Added a way for the --temp-dir option to be combined with a partial-dir
 1501:       setting that lets rsync avoid non-atomic updates (for those times when
 1502:       --temp-dir is not being used because space is tight).
 1503: 
 1504:     - A new support script, files-to-excludes, will transform a list of files
 1505:       into a set of include/exclude directives that will copy those files.
 1506: 
 1507:     - A new option, --executability (-E) can be used to preserve just the
 1508:       execute bit on files, for those times when using the --perms option is
 1509:       not desired.
 1510: 
 1511:     - The daemon now logs each connection and also each module-list request
 1512:       that it receives.
 1513: 
 1514:     - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
 1515:       (permission bits, e.g. "rwxr-xrwt").
 1516: 
 1517:     - The --dry-run option no longer forces the enabling of --verbose.
 1518: 
 1519:     - The --remove-sent-files option now does a better job of incrementally
 1520:       removing the sent files on the sending side (older versions tended to
 1521:       clump up all the removals at the end).
 1522: 
 1523:     - A daemon now supersedes its minimal SIGCHLD handler with the standard
 1524:       PID-remembering version after forking.  This ensures that the generator
 1525:       can get the child-exit status from the receiver.
 1526: 
 1527:     - Use of the --bwlimit option no longer interferes with the remote rsync
 1528:       sending error messages about invalid/refused options.
 1529: 
 1530:     - Rsync no longer returns a usage error when used with one local source arg
 1531:       and no destination: this now implies the --list-only option, just like
 1532:       the comparable situation with a remote source arg.
 1533: 
 1534:     - Added the --copy-dirlinks option, a more limited version of --copy-links.
 1535: 
 1536:     - Various documentation improvements, including: a better synopsis, some
 1537:       improved examples, a better discussion of the presence and absence of
 1538:       --perms (including how it interacts with the new --executability and
 1539:       --chmod options), an extended discussion of --temp-dir, an improved
 1540:       discussion of --partial-dir, a better description of rsync's pattern
 1541:       matching characters, an improved --no-implied-dirs section, and the
 1542:       documenting of what the --stats option outputs.
 1543: 
 1544:     - Various new and updated diffs in the patches dir, including: acls.diff,
 1545:       xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
 1546: 
 1547:   INTERNAL:
 1548: 
 1549:     - We now use sigaction() and sigprocmask() if possible, and fall back on
 1550:       signal() if not.  Using sigprocmask() ensures that rsync enables all the
 1551:       signals that it needs, just in case it was started in a masked state.
 1552: 
 1553:     - Some buffer sizes were expanded a bit, particularly on systems where
 1554:       MAXPATHLEN is overly small (e.g. cygwin).
 1555: 
 1556:     - If io_printf() tries to format more data than fits in the buffer, exit
 1557:       with an error instead of transmitting a truncated buffer.
 1558: 
 1559:     - If a va_copy macro is defined, lib/snprintf.c will use it when defining
 1560:       the VA_COPY macro.
 1561: 
 1562:     - Reduced the amount of stack memory needed for each level of directory
 1563:       recursion by nearly MAXPATHLEN bytes.
 1564: 
 1565:     - The wildmatch function was extended to allow an array of strings to be
 1566:       supplied as the string to match.  This allows the exclude code to do less
 1567:       string copying.
 1568: 
 1569:     - Got rid of the safe_fname() function (and all the myriad calls) and
 1570:       replaced it with a new function in the log.c code that filters all the
 1571:       output going to the terminal.
 1572: 
 1573:     - Unified the f_name() and the f_name_to() functions.
 1574: 
 1575:     - Improved the hash-table code the sender uses to handle checksums to make
 1576:       it use slightly less memory and run just a little faster.
 1577: 
 1578:   DEVELOPER RELATED:
 1579: 
 1580:     - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
 1581:       the previous -p0.  Also, the version included in the release tar now
 1582:       affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
 1583:       it is no longer necessary to run autoconf and/or yodl unless you're
 1584:       applying a patch that was checked out from CVS.
 1585: 
 1586:     - Several diffs in the patches dir now use the proper --enable-FOO
 1587:       configure option instead of --with-FOO to turn on the inclusion of
 1588:       the newly patched feature.
 1589: 
 1590:     - There is a new script, "prepare-source" than can be used to update the
 1591:       various generated files (proto.h, configure, etc.) even before configure
 1592:       has created the Makefile (this is mainly useful when patching the source
 1593:       with a patch that doesn't affect generated files).
 1594: 
 1595:     - The testsuite now sets HOME so that it won't be affected by a file such
 1596:       as ~/.popt.

 1599: NEWS for rsync 2.6.6 (28 Jul 2005)
 1600: Protocol: 29 (unchanged)
 1601: Changes since 2.6.5:
 1602: 
 1603:   SECURITY FIXES:
 1604: 
 1605:     - The zlib code was upgraded to version 1.2.3 in order to make it more
 1606:       secure.  While the widely-publicized security problem in zlib 1.2.2 did
 1607:       not affect rsync, another security problem surfaced that affects rsync's
 1608:       zlib 1.1.4.
 1609: 
 1610:   BUG FIXES:
 1611: 
 1612:     - The setting of flist->high in clean_flist() was wrong for an empty list.
 1613:       This could cause flist_find() to crash in certain rare circumstances
 1614:       (e.g. if just the right directory setup was around when --fuzzy was
 1615:       combined with --link-dest).
 1616: 
 1617:     - The outputting of hard-linked files when verbosity was > 1 was not right:
 1618:       (1) Without -i it would output the name of each hard-linked file as
 1619:       though it had been changed; it now outputs a "is hard linked" message for
 1620:       the file. (2) With -i it would output all dots for the unchanged
 1621:       attributes of a hard-link; it now changes those dots to spaces, as is
 1622:       done for other totally unchanged items.
 1623: 
 1624:     - When backing up a changed symlink or device, get rid of any old backup
 1625:       item so that we don't get an "already exists" error.
 1626: 
 1627:     - A couple places that were comparing a local and a remote modification-
 1628:       time were not honoring the --modify-window option.
 1629: 
 1630:     - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
 1631:       set too often (if some non-significant mode bits differed).
 1632: 
 1633:     - Fixed a really old, minor bug that could cause rsync to warn about being
 1634:       unable to mkdir() a path that ends in "/." because it just created the
 1635:       directory (required --relative, --no-implied-dirs, a source path that
 1636:       ended in either a trailing slash or a trailing "/.", and a non-existing
 1637:       destination dir to tickle the bug in a recent version).
 1638: 
 1639:   ENHANCEMENTS:
 1640: 
 1641:     - Made the "max verbosity" setting in the rsyncd.conf file settable on a
 1642:       per-module basis (which now matches the documentation).
 1643: 
 1644:     - The support/rrsync script has been upgraded to verify the args of options
 1645:       that take args (instead of rejecting any such options).  The script was
 1646:       also changed to try to be more secure and to fix a problem in the parsing
 1647:       of a pull operation that has multiple sources.
 1648: 
 1649:     - Improved the documentation that explains the difference between a
 1650:       normal daemon transfer and a daemon-over remote-shell transfer.
 1651: 
 1652:     - Some of the diffs supplied in the patches dir were fixed and/or
 1653:       improved.
 1654: 
 1655:   BUILD CHANGES:
 1656: 
 1657:     - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
 1658:       NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
 1659:       find in the /etc/group file).
 1660: 
 1661:     - Added a test to the test suite, itemized.test, that tests the output of
 1662:       -i (log-format w/%i) and some double-verbose messages.
 1663:

 1665: NEWS for rsync 2.6.5 (1 Jun 2005)
 1666: Protocol: 29 (unchanged)
 1667: Changes since 2.6.4:
 1668: 
 1669:   OUTPUT CHANGES:
 1670: 
 1671:     - Non-printable chars in filenames are now output using backslash-
 1672:       escaped characters rather than '?'s.  Any non-printable character is
 1673:       output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
 1674:       is now output as "\\".  Rsync also uses your locale setting, which
 1675:       can make it treat fewer high-bit characters as non-printable.
 1676: 
 1677:     - If rsync received an empty file-list when pulling files, it would
 1678:       output a "nothing to do" message and exit with a 0 (success) exit
 1679:       status, even if the remote rsync returned an error (it did not do
 1680:       this under the same conditions when pushing files).  This was changed
 1681:       to make the pulling behavior the same as the pushing behavior:  we
 1682:       now do the normal end-of-run outputting (depending on options) and
 1683:       exit with the appropriate exit status.
 1684: 
 1685:   BUG FIXES:
 1686: 
 1687:     - A crash bug was fixed when a daemon had its "path" set to "/", did
 1688:       not have chroot enabled, and used some anchored excludes in the
 1689:       rsyncd.conf file.
 1690: 
 1691:     - Fixed a bug in the transfer of a single file when -H is specified
 1692:       (rsync would either infinite loop or perhaps crash).
 1693: 
 1694:     - Fixed a case where the generator might try (and fail) to tweak the
 1695:       write-permissions of a read-only directory in list-only mode (this
 1696:       only caused an annoying warning message).
 1697: 
 1698:     - If --compare-dest or --link-dest uses a locally-copied file as the
 1699:       basis for an updated version, log this better when --verbose or -i
 1700:       is in effect.
 1701: 
 1702:     - Fixed the accidental disabling of --backup during the --delete-after
 1703:       processing.
 1704: 
 1705:     - Restored the ability to use the --address option in client mode (in
 1706:       addition to its use in daemon mode).
 1707: 
 1708:     - Make sure that some temporary progress information from the delete
 1709:       processing does not get left on the screen when it is followed by a
 1710:       newline.
 1711: 
 1712:     - When --existing skips a directory with extra verbosity, refer to it
 1713:       as a "directory", not a "file".
 1714: 
 1715:     - When transferring a single file to a different-named file, any
 1716:       generator messages that are source-file related no longer refer to
 1717:       the file by the destination filename.
 1718: 
 1719:     - Fixed a bug where hard-linking a group of files might fail if the
 1720:       generator hasn't created a needed destination directory yet.
 1721: 
 1722:     - Fixed a bug where a hard-linked group of files that is newly-linked
 1723:       to a file in a --link-dest dir doesn't link the files from the rest
 1724:       of the cluster.
 1725: 
 1726:     - When deleting files with the --one-file-system (-x) option set, rsync
 1727:       no longer tries to remove files from inside a mount-point on the
 1728:       receiving side.  Also, we don't complain about being unable to remove
 1729:       the mount-point dir.
 1730: 
 1731:     - Fixed a compatibility problem when using --cvs-ignore (-C) and
 1732:       sending files to an older rsync without using --delete.
 1733: 
 1734:     - Make sure that a "- !" or "+ !" include/exclude pattern does not
 1735:       trigger the list-clearing action that is reserved for "!".
 1736: 
 1737:     - Avoid a timeout in the generator when the sender/receiver aren't
 1738:       handling the generator's checksum output quickly enough.
 1739: 
 1740:     - Fixed the omission of some directories in the delete processing when
 1741:       --relative (-R) was combined with a source path that had a trailing
 1742:       slash.
 1743: 
 1744:     - Fixed a case where rsync would erroneously delete some files and then
 1745:       re-transfer them when the options --relative (-R) and --recursive
 1746:       (-r) were both enabled (along with --delete) and a source path had a
 1747:       trailing slash.
 1748: 
 1749:     - Make sure that --max-size doesn't affect a device or a symlink.
 1750: 
 1751:     - Make sure that a system with a really small MAXPATHLEN does not cause
 1752:       the buffers in readfd_unbuffered() to be too small to receive normal
 1753:       messages.  (This mainly affected Cygwin.)
 1754: 
 1755:     - If a source pathname ends with a filename of "..", treat it as if
 1756:       "../" had been specified (so that we don't copy files to the parent
 1757:       dir of the destination).
 1758: 
 1759:     - If --delete is combined with a file-listing rsync command (i.e. no
 1760:       transfer is happening), avoid outputting a warning that we couldn't
 1761:       delete anything.
 1762: 
 1763:     - If --stats is specified with --delete-after, ensure that all the
 1764:       "deleting" messages are output before the statistics.
 1765: 
 1766:     - Improved one "if" in the deletion code that was only checking errno
 1767:       for ENOTEMPTY when it should have also been checking for EEXIST (for
 1768:       compatibility with OS variations).
 1769: 
 1770:   ENHANCEMENTS:
 1771: 
 1772:     - Added the --only-write-batch=FILE option that may be used (instead
 1773:       of --write-batch=FILE) to create a batch file without doing any
 1774:       actual updating of the destination.  This allows you to divert all
 1775:       the file-updating data away from a slow data link (as long as you
 1776:       are pushing the data to the remote server when creating the batch).
 1777: 
 1778:     - When the generator is taking a long time to fill up its output buffer
 1779:       (e.g. if the transferred files are few, small, or missing), it now
 1780:       periodically flushes the output buffer so that the sender/receiver
 1781:       can get started on the files sooner rather than later.
 1782: 
 1783:     - Improved the keep-alive code to handle a long silence between the
 1784:       sender and the receiver that can occur when the sender is receiving
 1785:       the checksum data for a large file.
 1786: 
 1787:     - Improved the auth-errors that are logged by the daemon to include
 1788:       some information on why the authorization failed:  wrong user,
 1789:       password mismatch, etc.  (The client-visible message is unchanged!)
 1790: 
 1791:     - Improved the client's handling of an "@ERROR" from a daemon so that
 1792:       it does not complain about an unexpectedly closed socket (since we
 1793:       really did expect the socket to close).
 1794: 
 1795:     - If the daemon can't open the log-file specified in rsyncd.conf, fall
 1796:       back to using syslog and log an appropriate warning.  This is better
 1797:       than what was typically a totally silent (and fatal) failure (since a
 1798:       daemon is not usually run with the --no-detach option that was
 1799:       necessary to see the error on stderr).
 1800: 
 1801:     - The man pages now consistently refer to an rsync daemon as a "daemon"
 1802:       instead of a "server" (to distinguish it from the server process in a
 1803:       non-daemon transfer).
 1804: 
 1805:     - Made a small change to the rrsync script (restricted rsync -- in the
 1806:       support dir) to make a read-only server reject all --remove-* options
 1807:       when sending files (to future-proof it against the possibility of
 1808:       other similar options being added at some point).
 1809: 
 1810:   INTERNAL:
 1811: 
 1812:     - Rsync now calls setlocale(LC_CTYPE, "").  This enables isprint() to
 1813:       better discern which filename characters need to be escaped in
 1814:       messages (which should result in fewer escaped characters in some
 1815:       locales).
 1816: 
 1817:     - Improved the naming of the log-file open/reopen/close functions.
 1818: 
 1819:     - Removed some protocol-compatibility code that was only needed to help
 1820:       someone running a pre-release of 2.6.4.
 1821: 
 1822:   BUILD CHANGES:
 1823: 
 1824:     - Added configure option "--disable-locale" to disable any use of
 1825:       setlocale() in the binary.
 1826: 
 1827:     - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
 1828:       rsync from being built without symlink or hard-link support.
 1829: 
 1830:     - Only #define HAVE_REMSH if it is going to be set to 1.
 1831: 
 1832:     - Configure now disables the use of mkstemp() under HP-UX (since they
 1833:       refuse to fix its broken handling of large files).
 1834: 
 1835:     - Configure now explicitly checks for the lseek64() function so that
 1836:       the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
 1837:       presence based on the presence of the off64_t type.
 1838: 
 1839:     - Configure no longer mentions the change in the default remote-shell
 1840:       (from rsh to ssh) that occurred for the 2.6.0 release.
 1841: 
 1842:     - Some minor enhancements to the test scripts.
 1843: 
 1844:     - Added a few new *.diff files to the patches dir, including a patch
 1845:       that enables the optional copying of extended attributes.

 1848: NEWS for rsync 2.6.4 (30 March 2005)
 1849: Protocol: 29 (changed)
 1850: Changes since 2.6.3:
 1851: 
 1852:   OUTPUT CHANGES:
 1853: 
 1854:     - When rsync deletes a directory and outputs a verbose message about
 1855:       it, it now appends a trailing slash to the name instead of (only
 1856:       sometimes) outputting a preceding "directory " string.
 1857: 
 1858:     - The --stats output will contain file-list time-statistics if both
 1859:       sides are 2.6.4, or if the local side is 2.6.4 and the files are
 1860:       being pushed (since the stats come from the sending side).
 1861:       (Requires protocol 29 for a pull.)
 1862: 
 1863:     - The "%o" (operation) log-format escape now has a third value (besides
 1864:       "send" and "recv"):  "del." (with trailing dot to make it 4 chars).
 1865:       This changes the way deletions are logged in the daemon's log file.
 1866: 
 1867:     - When the --log-format option is combined with --verbose, rsync now
 1868:       avoids outputting the name of the file twice in most circumstances.
 1869:       As long as the --log-format item does not refer to any post-transfer
 1870:       items (such as %b or %c), the --log-format message is output prior to
 1871:       the transfer, so --verbose is now the equivalent of a --log-format of
 1872:       '%n%L' (which outputs the name and any link info).  If the log output
 1873:       must occur after the transfer to be complete, the only time the name
 1874:       is also output prior to the transfer is when --progress was specified
 1875:       (so that the name will precede the progress stats, and the full
 1876:       --log-format output will come after).
 1877: 
 1878:     - Non-printable characters in filenames are replaced with a '?' to
 1879:       avoid corrupting the screen or generating empty lines in the output.
 1880:   
 1881:   BUG FIXES:
 1882: 
 1883:     - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
 1884:       was only treating it as a special token in an rsync include/exclude
 1885:       file).
 1886: 
 1887:     - The combination of --verbose and --dry-run now mentions the full list
 1888:       of changes that would be output without --dry-run.
 1889: 
 1890:     - Avoid a mkdir warning when removing a directory in the destination
 1891:       that already exists in the --backup-dir.
 1892: 
 1893:     - An OS that has a binary mode for its files (such as cygwin) needed
 1894:       setmode(fd, O_BINARY) called on the temp-file we opened with
 1895:       mkstemp().  (Fix derived from cygwin's 2.6.3 rsync package.)
 1896: 
 1897:     - Fixed a potential hang when verbosity is high, the client side is
 1898:       the sender, and the file-list is large.
 1899: 
 1900:     - Fixed a potential protocol-corrupting bug where the generator could
 1901:       merge a message from the receiver into the middle of a multiplexed
 1902:       packet of data if only part of that data had been written out to the
 1903:       socket when the message from the generator arrived.
 1904: 
 1905:     - We now check if the OS doesn't support using mknod() for creating
 1906:       FIFOs and sockets, and compile-in some compatibility code using
 1907:       mkfifo() and socket() when necessary.
 1908: 
 1909:     - Fixed an off-by-one error in the handling of --max-delete=N.  Also,
 1910:       if the --max-delete limit is exceeded during a run, we now output a
 1911:       warning about this at the end of the run and exit with a new error
 1912:       code (25).
 1913: 
 1914:     - One place in the code wasn't checking if fork() failed.
 1915: 
 1916:     - The "ignore nonreadable" daemon parameter used to erroneously affect
 1917:       readable symlinks that pointed to a non-existent file.
 1918: 
 1919:     - If the OS does not have lchown() and a chown() of a symlink will
 1920:       affect the referent of a symlink (as it should), we no longer try
 1921:       to set the user and group of a symlink.
 1922: 
 1923:     - The generator now properly runs the hard-link loop and the dir-time
 1924:       rewriting loop after we're sure that the redo phase is complete.
 1925: 
 1926:     - When --backup was specified with --partial-dir=DIR, where DIR is a
 1927:       relative path, the backup code was erroneously trying to backup a
 1928:       file that was put into the partial-dir.
 1929: 
 1930:     - If a file gets resent in a single transfer and the --backup option is
 1931:       enabled along with --inplace, rsync no longer performs a duplicate
 1932:       backup (it used to overwrite the first backup with the failed file).
 1933: 
 1934:     - One call to flush_write_file() was not being checked for an error.
 1935: 
 1936:     - The --no-relative option was not being sent from the client to a
 1937:       server sender.
 1938: 
 1939:     - If an rsync daemon specified "dont compress = ..." for a file and the
 1940:       client tried to specify --compress, the libz code was not handling a
 1941:       compression level of 0 properly.  This could cause a transfer failure
 1942:       if the block-size for a file was large enough (e.g. rsync might have
 1943:       exited with an error for large files).
 1944: 
 1945:     - Fixed a bug that would sometimes surface when using --compress and
 1946:       sending a file with a block-size larger than 64K (either manually
 1947:       specified, or computed due to the file being really large).  Prior
 1948:       versions of rsync would sometimes fail to decompress the data
 1949:       properly, and thus the transferred file would fail its verification.
 1950: 
 1951:     - If a daemon can't open the specified log file (i.e. syslog is not
 1952:       being used), die without crashing.  We also output an error about
 1953:       the failure on stderr (which will only be seen if --no-detach was
 1954:       specified) and exit with a new error code (6).
 1955: 
 1956:     - A local transfer no longer duplicates all its include/exclude options
 1957:       (since the forked process already has a copy of the exclude list,
 1958:       there's no need to send them a set of duplicates).
 1959: 
 1960:     - The output of the items that are being updated by the generator (dirs,
 1961:       symlinks, devices) is now intermingled in the proper order with the
 1962:       output from the items that the receiver is updating (regular files)
 1963:       when pulling.  This misordering was particularly bad when --progress
 1964:       was specified.  (Requires protocol 29.)
 1965: 
 1966:     - When --timeout is specified, lulls that occur in the transfer while
 1967:       the generator is doing work that does not generate socket traffic
 1968:       (looking for changed files, deleting files, doing directory-time
 1969:       touch-ups, etc.) will cause a new keep-alive packet to be sent that
 1970:       should keep the transfer going as long as the generator continues to
 1971:       make progress.  (Requires protocol 29.)
 1972: 
 1973:     - The stat size of a device is not added to the total file size of the
 1974:       items in the transfer (the size might be undefined on some OSes).
 1975: 
 1976:     - Fixed a problem with refused-option messages sometimes not making it
 1977:       back to the client side when a remote --files-from was in effect and
 1978:       the daemon was the receiver.
 1979: 
 1980:     - The --compare-dest option was not updating a file that differed in
 1981:       (the preserved) attributes from the version in the compare-dest DIR.
 1982: 
 1983:     - When rsync is copying files into a write-protected directory, fixed
 1984:       the change-report output for the directory so that we don't report
 1985:       an identical directory as changed.
 1986: 
 1987:   ENHANCEMENTS:
 1988: 
 1989:     - Rsync now supports popt's option aliases, which means that you can
 1990:       use /etc/popt and/or ~/.popt to create your own option aliases.
 1991: 
 1992:     - Added the --delete-during (--del) option which will delete files
 1993:       from the receiving side incrementally as each directory in the
 1994:       transfer is being processed.  This makes it more efficient than the
 1995:       default, before-the-transfer behavior, which is now also available as
 1996:       --delete-before (and is still the default --delete-WHEN option that
 1997:       will be chosen if --delete or --delete-excluded is specified without
 1998:       a --delete-WHEN choice).  All the --del* options infer --delete, so
 1999:       an rsync daemon that refuses "delete" will still refuse to allow any
 2000:       file-deleting options (including the new --remove-sent-files option).
 2001: 
 2002:     - All the --delete-WHEN options are now more memory efficient:
 2003:       Previously an duplicate set of file-list objects was created on the
 2004:       receiving side for the entire destination hierarchy.  The new
 2005:       algorithm only creates one directory of objects at a time (for files
 2006:       inside the transfer).
 2007: 
 2008:     - Added the --copy-dest option, which works like --link-dest except
 2009:       that it locally copies identical files instead of hard-linking them.
 2010: 
 2011:     - Added support for specifying multiple --compare-dest, --copy-dest, or
 2012:       --link-dest options, but only of a single type. (Promoted from the
 2013:       patches dir and enhanced.) (Requires protocol 29.)
 2014: 
 2015:     - Added the --max-size option. (Promoted from the patches dir.)
 2016: 
 2017:     - The daemon-mode options are now separated from the normal rsync
 2018:       options so that they can't be mixed together.  This makes it
 2019:       impossible to start a daemon that has improper default option values
 2020:       (which could cause problems when a client connects, such as hanging
 2021:       or crashing).
 2022: 
 2023:     - The --bwlimit option may now be used in combination with --daemon
 2024:       to specify both a default value for the daemon side and a value
 2025:       that cannot be exceeded by a user-specified --bwlimit option.
 2026: 
 2027:     - Added the "port" parameter to the rsyncd.conf file. (Promoted from
 2028:       the patches dir.)  Also added "address".  The command-line options
 2029:       take precedence over a config-file option, as expected.
 2030: 
 2031:     - In _exit_cleanup(): when we are exiting with a partially-received
 2032:       file, we now flush any data in the write-cache before closing the
 2033:       partial file.
 2034: 
 2035:     - The --inplace support was enhanced to work with --compare-dest,
 2036:       --link-dest, and (the new) --copy-dest options. (Requires protocol
 2037:       29.)
 2038: 
 2039:     - Added the --dirs (-d) option for an easier way to copy directories
 2040:       without recursion.  Any directories that are encountered are created
 2041:       on the destination.  Specifying a directory with a trailing slash
 2042:       copies its immediate contents to the destination.
 2043: 
 2044:     - The --files-from option now implies --dirs (-d).
 2045: 
 2046:     - Added the --list-only option, which is mainly a way for the client to
 2047:       put the server into listing mode without needing to resort to any
 2048:       internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
 2049:       for a non-recursive listing).  This option is used automatically
 2050:       (behind the scenes) when a modern rsync speaks to a modern daemon,
 2051:       but may also be specified manually if you want to force the use of
 2052:       the --list-only option over a remote-shell connection.
 2053: 
 2054:     - Added the --omit-dir-times (-O) option, which will avoid updating
 2055:       the modified time for directories when --times was specified.  This
 2056:       option will avoid an extra pass through the file-list at the end of
 2057:       the transfer (to tweak all the directory times), which may provide
 2058:       an appreciable speedup for a really large transfer. (Promoted from
 2059:       the patches dir.)
 2060: 
 2061:     - Added the --filter (-f) option and its helper option, -F.  Filter
 2062:       rules are an extension to the existing include/exclude handling
 2063:       that also supports nested filter files as well as per-directory
 2064:       filter files (like .cvsignore, but with full filter-rule parsing).
 2065:       This new option was chosen in order to ensure that all existing
 2066:       include/exclude processing remained 100% compatible with older
 2067:       versions.  Protocol 29 is needed for full filter-rule support, but
 2068:       backward-compatible rules work with earlier protocol versions.
 2069:       (Promoted from the patches dir and enhanced.)
 2070: 
 2071:     - Added the --delay-updates option that puts all updated files into
 2072:       a temporary directory (by default ".~tmp~", but settable via the
 2073:       --partial-dir=DIR option) until the end of the transfer.  This
 2074:       makes the updates a little more atomic for a large transfer.
 2075: 
 2076:     - If rsync is put into the background, any output from --progress is
 2077:       reduced.
 2078: 
 2079:     - Documented the "max verbosity" setting for rsyncd.conf.  (This
 2080:       setting was added a couple releases ago, but left undocumented.)
 2081: 
 2082:     - The sender and the generator now double-check the file-list index
 2083:       they are given, and refuse to try to do a file transfer on a
 2084:       non-file index (since that would indicate that something had gone
 2085:       very wrong).
 2086: 
 2087:     - Added the --itemize-changes (-i) option, which is a way to output a
 2088:       more detailed list of what files changed and in what way.  The effect
 2089:       is the same as specifying a --log-format of "%i %n%L" (see both the
 2090:       rsync and rsyncd.conf manpages).  Works with --dry-run too.
 2091: 
 2092:     - Added the --fuzzy (-y) option, which attempts to find a basis file
 2093:       for a file that is being created from scratch.  The current algorithm
 2094:       only looks in the destination directory for the created file, but it
 2095:       does attempt to find a match based on size/mod-time (in case the file
 2096:       was renamed with no other changes) as well as based on a fuzzy
 2097:       name-matching algorithm.  This option requires protocol 29 because it
 2098:       needs the new file-sorting order.  (Promoted from patches dir and
 2099:       enhanced.) (Requires protocol 29.)
 2100: 
 2101:     - Added the --remove-sent-files option, which lets you move files
 2102:       between systems.
 2103: 
 2104:     - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
 2105:       enclosed in '[' and ']' (e.g. "[::1]").  (We already allowed IPv6
 2106:       literals in the rsync://HOST:PORT/PATH format.)
 2107: 
 2108:     - When rsync recurses to build the file list, it no longer keeps open
 2109:       one or more directory handles from the dir's parent dirs.
 2110: 
 2111:     - When building under windows, the default for --daemon is now to
 2112:       avoid detaching, requiring the new --detach option to force rsync
 2113:       to detach.
 2114: 
 2115:     - The --dry-run option can now be combined with either --write-batch or
 2116:       --read-batch, allowing you to run a do-nothing test command to see
 2117:       what would happen without --dry-run.
 2118: 
 2119:     - The daemon's "read only" config item now sets an internal read_only
 2120:       variable that makes extra sure that no write/delete calls on the
 2121:       read-only side can succeed.
 2122: 
 2123:     - The log-format % escapes can now have a numeric field width in
 2124:       between the % and the escape letter (e.g. "%-40n %08p").
 2125: 
 2126:     - Improved the option descriptions in the --help text.
 2127: 
 2128:   SUPPORT FILES:
 2129: 
 2130:     - Added atomic-rsync to the support dir: a perl script that will
 2131:       transfer some files using rsync, and then move the updated files into
 2132:       place all at once at the end of the transfer.  Only works when
 2133:       pulling, and uses --link-dest and a parallel hierarchy of files to
 2134:       effect its update.
 2135: 
 2136:     - Added mnt-excl to the support dir: a perl script that takes the
 2137:       /proc/mounts file and translates it into a set of excludes that will
 2138:       exclude all mount points (even mapped mounts to the same disk).  The
 2139:       excludes are made relative to the specified source dir and properly
 2140:       anchored.
 2141: 
 2142:     - Added savetransfer.c to the support dir: a C program that can make
 2143:       a copy of all the data that flows over the wire.  This lets you test
 2144:       for data corruption (by saving the data on both the sending side and
 2145:       the receiving side) and provides one way to debug a protocol error.
 2146: 
 2147:     - Added rrsync to the support dir: this is an updated version of Joe
 2148:       Smith's restricted rsync perl script.  This helps to ensure that only
 2149:       certain rsync commands can be run by an ssh invocation.
 2150: 
 2151:   INTERNAL:
 2152: 
 2153:     - Added better checking of the checksum-header values that come over
 2154:       the socket.
 2155: 
 2156:     - Merged a variety of file-deleting functions into a single function so
 2157:       that it is easier to maintain.
 2158: 
 2159:     - Improved the type of some variables (particularly blocksize vars) for
 2160:       consistency and proper size.
 2161: 
 2162:     - Got rid of the uint64 type (which we didn't need).
 2163: 
 2164:     - Use a slightly more compatible set of core #include directives.
 2165: 
 2166:     - Defined int32 in a way that ensures that the build dies if we can't
 2167:       find a variable with at least 32 bits.
 2168: 
 2169:   PROTOCOL DIFFERENCES FOR VERSION 29:
 2170: 
 2171:     - A 16-bit flag-word is transmitted after every file-list index.  This
 2172:       indicates what is changing between the sender and the receiver.  The
 2173:       generator now transmits an index and a flag-word to indicate when
 2174:       dirs and symlinks have changed (instead of producing a message),
 2175:       which makes the outputting of the information more consistent and
 2176:       less prone to screen corruption (because the local receiver/sender is
 2177:       now outputting all the file-change info messages).
 2178: 
 2179:     - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
 2180:       in the flag-word and the name of the file that was linked immediately
 2181:       follows in vstring format (see below).
 2182: 
 2183:     - If a file is being transferred with an alternate-basis file, the
 2184:       ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
 2185:       byte follows, indicating what type of basis file was chosen.  If that
 2186:       indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
 2187:       is set in the flag-word and the name of the match in vstring format
 2188:       follows the basis byte.  A vstring is a variable length string that
 2189:       has its size written prior to the string, and no terminating null.
 2190:       If the string is from 1-127 bytes, the length is a single byte.  If
 2191:       it is from 128-32767 bytes, the length is written as ((len >> 8) |
 2192:       0x80) followed by (len % 0x100).
 2193: 
 2194:     - The sending of exclude names is done using filter-rule syntax.  This
 2195:       means that all names have a prefixed rule indicator, even excludes
 2196:       (which used to be sent as a bare pattern, when possible).  The -C
 2197:       option will include the per-dir .cvsignore merge file in the list of
 2198:       filter rules so it is positioned correctly (unlike in some older
 2199:       transfer scenarios).
 2200: 
 2201:     - Rsync sorts the filename list in a different way: it sorts the subdir
 2202:       names after the non-subdir names for each dir's contents, and it
 2203:       always puts a dir's contents immediately after the dir's name in the
 2204:       list.  (Previously an item named "foo.txt" would sort in between
 2205:       directory "foo/" and "foo/bar".)
 2206: 
 2207:     - When talking to a protocol 29 rsync daemon, a list-only request
 2208:       is able to note this before the options are sent over the wire and
 2209:       the new --list-only option is included in the options.
 2210: 
 2211:     - When the --stats bytes are sent over the wire (or stored in a batch),
 2212:       they now include two elapsed-time values: one for how long it took to
 2213:       build the file-list, and one for how long it took to send it over the
 2214:       wire (each expressed in thousandths of a second).
 2215: 
 2216:     - When --delete-excluded is specified with some filter rules (AKA
 2217:       excludes), a client sender will now initiate a send of the rules to
 2218:       the receiver (older protocols used to omit the sending of excludes in
 2219:       this situation since there were no receiver-specific rules that
 2220:       survived --delete-excluded back then).  Note that, as with all the
 2221:       filter-list sending, only items that are significant to the other
 2222:       side will actually be sent over the wire, so the filter-rule list
 2223:       that is sent in this scenario is often empty.
 2224: 
 2225:     - An index equal to the file-list count is sent as a keep-alive packet
 2226:       from the generator to the sender, which then forwards it on to the
 2227:       receiver.  This normally invalid index is only a valid keep-alive
 2228:       packet if the 16-bit flag-word that follows it contains a single bit
 2229:       (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
 2230: 
 2231:     - A protocol-29 batch file includes a bit for the setting of the --dirs
 2232:       option and for the setting of the --compress option.  Also, the shell
 2233:       script created by --write-batch will use the --filter option instead
 2234:       of --exclude-from to capture any filter rules.
 2235: 
 2236:   BUILD CHANGES:
 2237: 
 2238:     - Handle an operating system that use mkdev() in place of makedev().
 2239: 
 2240:     - Improved configure to better handle cross-compiling.

 2243: NEWS for rsync 2.6.3 (30 Sep 2004)
 2244: Protocol: 28 (unchanged)
 2245: Changes since 2.6.2:
 2246: 
 2247:   SECURITY FIXES:
 2248: 
 2249:     - A bug in the sanitize_path routine (which affects a non-chrooted
 2250:       rsync daemon) could allow a user to craft a pathname that would get
 2251:       transformed into an absolute path for certain options (but not for
 2252:       file-transfer names).  If you're running an rsync daemon with chroot
 2253:       disabled, *please upgrade*, ESPECIALLY if the user privs you run
 2254:       rsync under is anything above "nobody".
 2255: 
 2256:   OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
 2257: 
 2258:     - Please note that the 2-line footer (output when verbose) now uses the
 2259:       term "sent" instead of "wrote" and "received" instead of "read".  If
 2260:       you are not parsing the numeric values out of this footer, a script
 2261:       would be better off using the empty line prior to the footer as the
 2262:       indicator that the verbose output is over.
 2263:       
 2264:     - The output from the --stats option was similarly affected to change
 2265:       "written" to "sent" and "read" to "received".
 2266: 
 2267:     - Rsync ensures that a filename that contains a newline gets mentioned
 2268:       with each newline transformed into a question mark (which prevents a
 2269:       filename from causing an empty line to be output).
 2270: 
 2271:     - The "backed up ..." message that is output when at least 2 --verbose
 2272:       options are specified is now the same both with and without the
 2273:       --backup-dir option.
 2274: 
 2275:   BUG FIXES:
 2276: 
 2277:     - Fixed a crash bug that might appear when --delete was used and
 2278:       multiple source directories were specified.
 2279: 
 2280:     - Fixed a 32-bit truncation of the file length when generating the
 2281:       checksums.
 2282: 
 2283:     - The --backup code no longer attempts to create some directories
 2284:       over and over again (generating warnings along the way).
 2285: 
 2286:     - Fixed a bug in the reading of the secrets file (by the daemon) and
 2287:       the password file (by the client):  the files no longer need to be
 2288:       terminated by a newline for their content to be read in.
 2289: 
 2290:     - If a file has a read error on the sending side or the reconstructed
 2291:       data doesn't match the expected checksum (perhaps due to the basis
 2292:       file changing during the transfer), the receiver will no longer
 2293:       retain the resulting file unless the --partial option was specified.
 2294:       (Note: for the read-error detection to work, neither side can be
 2295:       older than 2.6.3 -- older receivers will always retain the file, and
 2296:       older senders don't tell the receiver that the file had a read
 2297:       error.)
 2298: 
 2299:     - If a file gets resent in a single transfer and the --backup option
 2300:       is enabled, rsync no longer performs a duplicate backup (it used to
 2301:       overwrite the original file in the backup area).
 2302: 
 2303:     - Files specified in the daemon's "exclude" or "exclude from" config
 2304:       items are now excluded from being uploaded (assuming that the module
 2305:       allows uploading at all) in addition to the old download exclusion.
 2306: 
 2307:     - Got rid of a potential hang in the receiver when near the end of a
 2308:       phase.
 2309: 
 2310:     - When using --backup without a --backup-dir, rsync no longer preserves
 2311:       the modify time on directories.  This avoids confusing NFS.
 2312: 
 2313:     - When --copy-links (-L) is specified, we now output a separate error
 2314:       for a symlink that has no referent instead of claiming that a file
 2315:       "vanished".
 2316: 
 2317:     - The --copy-links (-L) option no longer has the side-effect of telling
 2318:       the receiving side to follow symlinks.  See the --keep-dirlinks
 2319:       option (mentioned below) for a way to specify that behavior.
 2320: 
 2321:     - Error messages from the daemon server's option-parsing (such as
 2322:       refused options) are now successfully transferred back to the client
 2323:       (the server used to fail to send the message because the socket
 2324:       wasn't in the right state for the message to get through).
 2325: 
 2326:     - Most transfer errors that occur during a daemon transfer are now
 2327:       returned to the user in addition to being logged (some messages are
 2328:       intended to be daemon-only and are not affected by this).
 2329: 
 2330:     - Fixed a bug in the daemon authentication code when using one of the
 2331:       batch-processing options.
 2332: 
 2333:     - We try to work around some buggy IPv6 implementations that fail to
 2334:       implement IPV6_V6ONLY.  This should fix the "address in use" error
 2335:       that some daemons get when running on an OS with a buggy IPv6
 2336:       implementation.  Also, if the new code gets this error, we might
 2337:       suggest that the user specify --ipv4 or --ipv6 (if we think it will
 2338:       help).
 2339: 
 2340:     - When the remote rsync dies, make a better effort to recover any error
 2341:       messages it may have sent before dying (the local rsync used to just
 2342:       die with a socket-write error).
 2343: 
 2344:     - When using --delete and a --backup-dir that contains files that are
 2345:       hard-linked to their destination equivalents, rsync now makes sure
 2346:       that removed files really get removed (avoids a really weird rename()
 2347:       behavior).
 2348: 
 2349:     - Avoid a bogus run-time complaint about a lack of 64-bit integers when
 2350:       the int64 type is defined as an off_t and it actually has 64-bits.
 2351: 
 2352:     - Added a configure check for open64() without mkstemp64() so that we
 2353:       can avoid using mkstemp() when such a combination is encountered.
 2354:       This bypasses a problem writing out large temp files on OSes such as
 2355:       AIX and HP-UX.
 2356: 
 2357:     - Fixed an age-old crash problem with --read-batch on a local copy
 2358:       (rsync was improperly assuming --whole-file for the local copy).
 2359: 
 2360:     - When --dry-run (-n) is used and the destination directory does not
 2361:       exist, rsync now produces a correct report of files that would be
 2362:       sent instead of dying with a chdir() error.
 2363: 
 2364:     - Fixed a bug that could cause a slow-to-connect rsync daemon to die
 2365:       with an error instead of waiting for the connection to finish.
 2366: 
 2367:     - Fixed an ssh interaction that could cause output to be lost when the
 2368:       user chose to combine the output of rsync's stdout and stderr (e.g.
 2369:       using the "2>&1").
 2370: 
 2371:     - Fixed an option-parsing bug when --files-from got passed to a daemon.
 2372: 
 2373:   ENHANCEMENTS:
 2374: 
 2375:     - Added the --partial-dir=DIR option that lets you specify where to
 2376:       (temporarily) put a partially transferred file (instead of over-
 2377:       writing the destination file).  E.g.  --partial-dir=.rsync-partial
 2378:       Also added support for the RSYNC_PARTIAL_DIR environment variable
 2379:       that, when found, transforms a regular --partial option (such as
 2380:       the convenient -P option) into one that also specifies a directory.
 2381: 
 2382:     - Added --keep-dirlinks (-K), which allows you to symlink a directory
 2383:       onto another partition on the receiving side and have rsync treat it
 2384:       as matching a normal directory from the sender.
 2385: 
 2386:     - Added the --inplace option that tells rsync to write each destination
 2387:       file without using a temporary file.  The matching of existing data
 2388:       in the destination file can be severely limited by this, but there
 2389:       are also cases where this is more efficient (such as appending data).
 2390:       Use only when needed (see the man page for more details).
 2391: 
 2392:     - Added the "write only" option for the daemon's config file.
 2393: 
 2394:     - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
 2395:       and documented all these options in the man page.
 2396: 
 2397:     - Improved the handling of the --bwlimit option so that it's less
 2398:       bursty, more accurate, and works properly over a larger range of
 2399:       values.
 2400: 
 2401:     - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
 2402:       SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
 2403: 
 2404:     - Added the --checksum-seed=N option for advanced users.
 2405: 
 2406:     - Batch writing/reading has a brand-new implementation that is simpler,
 2407:       fixes a few weird problems with the old code (such as no longer
 2408:       sprinkling the batch files into different dirs or even onto different
 2409:       systems), and is much less intrusive into the code (making it easier
 2410:       to maintain for the future).  The new code generates just one data
 2411:       file instead of three, which makes it possible to read the batch on
 2412:       stdin via a remote shell.  Also, the old requirement of forcing the
 2413:       same fixed checksum-seed for all batch processing has been removed.
 2414: 
 2415:     - If an rsync daemon has a module set with "list = no" (which hides its
 2416:       presence in the list of available modules), a user that fails to
 2417:       authenticate gets the same "unknown module" error that they would get
 2418:       if the module were actually unknown (while still logging the real
 2419:       error to the daemon's log file).  This prevents fishing for module
 2420:       names.
 2421: 
 2422:     - The daemon's "refuse options" config item now allows you to match
 2423:       option names using wildcards and/or the single-letter option names.
 2424: 
 2425:     - Each transferred file now gets its permissions and modified-time
 2426:       updated before the temp-file gets moved into place.  Previously, the
 2427:       finished file would have a very brief window where its permissions
 2428:       disallowed all group and world access.
 2429: 
 2430:     - Added the ability to parse a literal IPv6 address in an "rsync:" URL
 2431:       (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
 2432: 
 2433:     - The daemon's wildcard expanding code can now handle more than 1000
 2434:       filenames (it's now limited by memory instead of having a hard-wired
 2435:       limit).
 2436: 
 2437:   INTERNAL:
 2438: 
 2439:     - Some cleanup in the exclude code has saved some per-exclude memory
 2440:       and made the code easier to maintain.
 2441: 
 2442:     - Improved the argv-overflow checking for a remote command that has a
 2443:       lot of args.
 2444: 
 2445:     - Use rsyserr() in the various places that were still calling rprintf()
 2446:       with strerror() as an arg.
 2447: 
 2448:     - If an rsync daemon is listening on multiple sockets (to handle both
 2449:       IPv4 and IPv6 to a single port), we now close all the unneeded file
 2450:       handles after we accept a connection (we used to close just one of
 2451:       them).
 2452: 
 2453:     - Optimized the handling of larger block sizes (rsync used to slow to a
 2454:       crawl if the block size got too large).
 2455: 
 2456:     - Optimized away a loop in hash_search().
 2457: 
 2458:     - Some improvements to the sanitize_path() and clean_fname() functions
 2459:       makes them more efficient and produce better results (while still
 2460:       being compatible with the file-name cleaning that gets done on both
 2461:       sides when sending the file-list).
 2462: 
 2463:     - Got rid of alloc_sanitize_path() after adding a destination-buffer
 2464:       arg to sanitize_path() made it possible to put all the former's
 2465:       functionality into the latter.
 2466: 
 2467:     - The file-list that is output when at least 4 verbose options are
 2468:       specified reports the uid value on the sender even when rsync is
 2469:       not running as root (since we might be sending to a root receiver).
 2470: 
 2471:   BUILD CHANGES:
 2472: 
 2473:     - Added a "gen" target to rebuild most of the generated files,
 2474:       including configure, config.h.in, the man pages, and proto.h.
 2475: 
 2476:     - If "make proto" doesn't find some changes in the prototypes, the
 2477:       proto.h file is left untouched (its time-stamp used to always be
 2478:       updated).
 2479: 
 2480:     - The variable $STRIP (that is optionally set by the install-strip
 2481:       target's rule) was changed to $INSTALL_STRIP because some systems
 2482:       have $STRIP already set in the environment.
 2483: 
 2484:     - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
 2485: 
 2486:     - When cross-compiling, the gettimeofday() function is now assumed to
 2487:       be a modern version that takes two-args (since we can't test it).
 2488: 
 2489:   DEVELOPER RELATED:
 2490: 
 2491:     - The scripts in the testsuite dir were cleaned up a bit and a few
 2492:       new tests added.
 2493: 
 2494:     - Some new diffs were added to the patches dir, and some accepted
 2495:       ones were removed.

 2498: NEWS for rsync 2.6.2 (30 Apr 2004)
 2499: Protocol: 28 (unchanged)
 2500: Changes since 2.6.1:
 2501: 
 2502:   BUG FIXES:
 2503: 
 2504:     - Fixed a major bug in the sorting of the filenames when --relative
 2505:       is used for some sources (just sources such as "/" and "/*" were
 2506:       affected).  This fix ensures that we ask for the right file-list
 2507:       item when requesting changes from the sender.
 2508: 
 2509:     - Rsync now checks the return value of the close() function to
 2510:       better report disk-full problems on an NFS file system.
 2511: 
 2512:     - Restored the old daemon-server behavior of logging error messages
 2513:       rather than returning them to the user.  (A better long-term fix
 2514:       will be sought in the future.)
 2515: 
 2516:     - An obscure uninitialized-variable bug was fixed in the uid/gid
 2517:       code.  (This bug probably had no ill effects.)
 2518: 
 2519:   BUILD CHANGES:
 2520: 
 2521:     - Got rid of the configure check for sys/sysctl.h (it wasn't used
 2522:       and was causing a problem on some systems).  Also improved the
 2523:       broken-largefile-locking test to try to avoid failure due to an
 2524:       NFS build-dir.
 2525: 
 2526:     - Fixed a compile problem on systems that don't define
 2527:       AI_NUMERICHOST.
 2528: 
 2529:     - Fixed a compile problem in the popt source for compilers that
 2530:       don't support __attribute__.
 2531: 
 2532:   DEVELOPER RELATED:
 2533: 
 2534:     - Improved the testsuite's "merge" test to work on OSF1.
 2535: 
 2536:     - Two new diffs were added to the patches dir.
 2537: 
 2538: 
 2539: NEWS for rsync 2.6.1 (26 Apr 2004)
 2540: Protocol: 28 (changed)
 2541: Changes since 2.6.0:
 2542: 
 2543:   SECURITY FIXES:
 2544: 
 2545:     - Paths sent to an rsync daemon are more thoroughly sanitized when
 2546:       chroot is not used.  If you're running a non-read-only rsync
 2547:       daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
 2548:       user privs you run rsync under is anything above "nobody".
 2549: 
 2550:   ENHANCEMENTS:
 2551: 
 2552:     - Lower memory use, more optimal transfer of data over the socket,
 2553:       and lower CPU usage (see the INTERNAL section for details).
 2554: 
 2555:     - The RSYNC_PROXY environment variable can now contain a
 2556:       "USER:PASS@" prefix before the "HOST:PORT" information.
 2557:       (Bardur Arantsson)
 2558: 
 2559:     - The --progress output now mentions how far along in the transfer
 2560:       we are, including both a count of files transferred and a
 2561:       percentage of the total file-count that we've processed.  It also
 2562:       shows better current-rate-of-transfer and remaining-transfer-time
 2563:       values.
 2564: 
 2565:     - Documentation changes now attempt to describe some often mis-
 2566:       understood features more clearly.
 2567: 
 2568:   BUG FIXES:
 2569: 
 2570:     - When -x (--one-file-system) is combined with -L (--copy-links) or
 2571:       --copy-unsafe-links, no symlinked files are skipped, even if the
 2572:       referent file is on a different filesystem.
 2573: 
 2574:     - The --link-dest code now works properly for a non-root user when
 2575:       (1) the UIDs of the source and destination differ and -o was
 2576:       specified, or (2) when the group of the source can't be used on
 2577:       the destination and -g was specified.
 2578: 
 2579:     - Fixed a bug in the handling of -H (hard-links) that might cause
 2580:       the expanded PATH/NAME value of the current item to get
 2581:       overwritten (due to an expanded-name caching bug).
 2582:       
 2583:     - We now reset the "new data has been sent" flag at the start of
 2584:       each file we send.  This makes sure that an interrupted transfer
 2585:       with the --partial option set doesn't keep a shorter temp file
 2586:       than the current basis file when no new data has been transferred
 2587:       over the wire for that file.
 2588: 
 2589:     - Fixed a byte-order problem in --batch-mode on big-endian machines.
 2590:       (Jay Fenlason)
 2591: 
 2592:     - When using --cvs-exclude, the exclude items we get from a
 2593:       per-directory's .cvsignore file once again only affect that one
 2594:       directory (not all following directories too).  The items are also
 2595:       now properly word-split and parsed without any +/- prefix parsing.
 2596: 
 2597:     - When specifying the USER@HOST: prefix for a file, the USER part
 2598:       can now contain an '@', if needed (i.e. the last '@' is used to
 2599:       find the HOST, not the first).
 2600: 
 2601:     - Fixed some bugs in the handling of group IDs for non-root users:
 2602:       (1) It properly handles a group that the sender didn't have a name
 2603:       for (it would previously skip changing the group on any files in
 2604:       that group).  (2) If --numeric-ids is used, rsync no longer
 2605:       attempts to set groups that the user doesn't have the permission
 2606:       to set.
 2607: 
 2608:     - Fixed the "refuse options" setting in the rsyncd.conf file.
 2609: 
 2610:     - Improved the -x (--one-file-system) flag's handling of any mount-
 2611:       point directories we encounter.  It is both more optimal (in that
 2612:       it no longer does a useless scan of the contents of the mount-
 2613:       point dirs) and also fixes a bug where a remapped mount of the
 2614:       original filesystem could get discovered in a subdir we should be
 2615:       ignoring.
 2616: 
 2617:     - Rsync no longer discards a double-slash at the start of a filename
 2618:       when trying to open the file.  It also no longer constructs names
 2619:       that start with a double slash (unless the user supplied them).
 2620: 
 2621:     - Path-specifying options to a daemon should now work the same with
 2622:       or without chroot turned on.  Previously, such a option (such as
 2623:       --link-dest) would get its absolute path munged into a relative
 2624:       one if chroot was not on, making that setting fairly useless.
 2625:       Rsync now transforms the path into one that is based on the
 2626:       module's base dir when chroot is not enabled.
 2627: 
 2628:     - Fixed a compatibility problem interacting with older rsync
 2629:       versions that might send us an empty --suffix value without
 2630:       telling us that --backup-dir was specified.
 2631: 
 2632:     - The "hosts allow" option for a daemon-over-remote-shell process
 2633:       now has improved support for IPv6 addresses and a fix for systems
 2634:       that have a length field in their socket structs.
 2635: 
 2636:     - Fixed the ability to request an empty backup --suffix when sending
 2637:       files to an rsync daemon.
 2638: 
 2639:     - Fixed an option-parsing bug when --files-from was sent to a server
 2640:       sender.
 2641: 
 2642:   INTERNAL:
 2643: 
 2644:     - Most of the I/O is now buffered, which results in a pretty large
 2645:       speedup when running under MS Windows.  (Craig Barratt)
 2646: 
 2647:     - Optimizations to the name-handling/comparing code have made some
 2648:       significant reductions in user-CPU time for large file sets.
 2649: 
 2650:     - Some cleanup of the variable types make the code more consistent.
 2651: 
 2652:     - Reduced memory requirements of hard link preservation.
 2653:       (J.W. Schultz)
 2654: 
 2655:     - Implemented a new algorithm for hard-link handling that speeds up
 2656:       the code significantly.  (J.W. Schultz and Wayne Davison)
 2657: 
 2658:     - The --hard-link option now uses the first existing file in the
 2659:       group of linked files as the basis for the transfer.  This
 2660:       prevents the sub-optimal transfer of a file's data when a new
 2661:       hardlink is added on the sending side and it sorts alphabetically
 2662:       earlier in the list than the files that are already present on the
 2663:       receiving side.
 2664: 
 2665:     - Dropped support for protocol versions less than 20 (2.3.0 released
 2666:       15 Mar 1999) and activated warnings for protocols less than 25
 2667:       (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
 2668:       severally)
 2669: 
 2670:     - More optimal data transmission for --hard-links (protocol 28).
 2671: 
 2672:     - More optimal data transmission for --checksum (protocol 28).
 2673: 
 2674:     - Less memory is used when --checksum is specified.
 2675: 
 2676:     - Less memory is used in the file list (a per-file savings).
 2677: 
 2678:     - The generator is now better about not modifying the file list
 2679:       during the transfer in order to avoid a copy-on-write memory
 2680:       bifurcation (on systems where fork() uses shared memory).
 2681:       Previously, rsync's shared memory would slowly become unshared,
 2682:       resulting in real memory usage nearly doubling on the receiving
 2683:       side by the end of the transfer.  Now, as long as permissions
 2684:       are being preserved, the shared memory should remain that way
 2685:       for the entire transfer.
 2686: 
 2687:     - Changed hardlink info and file_struct + strings to use allocation
 2688:       pools.  This reduces memory use for large file-sets and permits
 2689:       freeing memory to the OS.  (J.W. Schultz) 
 2690: 
 2691:     - The 2 pipes used between the receiver and generator processes
 2692:       (which are forked on the same machine) were reduced to 1 pipe and
 2693:       the protocol improved so that (1) it is now impossible to have the
 2694:       "redo" pipe fill up and hang rsync, and (2) trailing messages from
 2695:       the receiver don't get lost on their way through the generator
 2696:       over to the sender (which mainly affected hard-link messages and
 2697:       verbose --stats output).
 2698: 
 2699:     - Improved the internal uid/gid code to be more portable and a
 2700:       little more optimized.
 2701: 
 2702:     - The device numbers sent when using --devices are now sent as
 2703:       separate major/minor values with 32-bit accuracy (protocol 28).
 2704:       Previously, the copied devices were sent as a single 32-bit
 2705:       number.  This will make inter-operation of 64-bit binaries more
 2706:       compatible with their 32-bit brethren (with both ends of the
 2707:       connection are using protocol 28).  Note that optimizations in the
 2708:       binary protocol for sending the device numbers often results in
 2709:       fewer bytes being used than before, even though more precision is
 2710:       now available.
 2711: 
 2712:     - Some cleanup of the exclude/include structures and its code made
 2713:       things clearer (internally), simpler, and more efficient.
 2714: 
 2715:     - The reading & writing of the file-list in batch-mode is now
 2716:       handled by the same code that sends & receives the list over the
 2717:       wire.  This makes it much easier to maintain.  (Note that the
 2718:       batch code is still considered to be experimental.)
 2719: 
 2720:   BUILD CHANGES:
 2721: 
 2722:     - The configure script now accepts --with-rsyncd-conf=PATH to
 2723:       override the default value of the /etc/rsyncd.conf file.
 2724: 
 2725:     - Fixed configure bug when running "./configure --disable-ipv6".
 2726: 
 2727:     - Fixed compilation problem on Tru64 Unix (having to do with
 2728:       sockaddr.sa_len and sockaddr.sin_len).
 2729: 
 2730:   DEVELOPER RELATED:
 2731: 
 2732:     - Fixed "make test" bug when build dir is not the source dir.
 2733: 
 2734:     - Added a couple extra diffs in the "patches" dir, removed the ones
 2735:       that got applied, and rebuilt the rest.

 2738: NEWS for rsync 2.6.0 (1 Jan 2004)
 2739: Protocol: 27 (changed)
 2740: Changes since 2.5.7:
 2741: 
 2742:   ENHANCEMENTS:
 2743: 
 2744:     * "ssh" is now the default remote shell for rsync.  If you want to
 2745:       change this, configure like this:  "./configure --with-rsh=rsh".
 2746: 
 2747:     * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
 2748:       Note that --from0 affects the line-ending character for all the
 2749:       files read by the --*-from options. (Wayne Davison)
 2750: 
 2751:     * Length of csum2 is now per-file starting with protocol version
 2752:       27. (J.W. Schultz)
 2753: 
 2754:     * Per-file dynamic block size is now sqrt(file length).  The
 2755:       per-file checksum size is determined according to an algorithm
 2756:       provided by Donovan Baarda which reduces the probability of rsync
 2757:       algorithm corrupting data and falling back using the whole md4
 2758:       checksums. (J.W. Schultz, Donovan Baarda)
 2759: 
 2760:     * The --stats option no longer includes the (debug) malloc summary
 2761:       unless the verbose option was specified at least twice.
 2762: 
 2763:     * Added a new error/warning code for when files vanish from the
 2764:       sending side.  Made vanished source files not interfere with the
 2765:       file-deletion pass when --delete-after was specified.
 2766: 
 2767:     * Various trailing-info sections are now preceded by a newline.
 2768: 
 2769:   BUG FIXES:
 2770: 
 2771:     * Fixed several exclude/include matching bugs when using wild-cards.
 2772:       This has a several user-visible effects, all of which make the
 2773:       matching more consistent and intuitive.  This should hopefully not
 2774:       cause anyone problems since it makes the matching work more like
 2775:       what people are expecting. (Wayne Davison)
 2776: 
 2777:       - A pattern with a "**" no longer causes a "*" to match slashes.
 2778:         For example, with "/*/foo/**", "foo" must be 2 levels deep.
 2779: 	[If your string has BOTH "*" and "**" wildcards, changing the
 2780: 	"*" wildcards to "**" will provide the old behavior in all
 2781: 	versions.]
 2782: 
 2783:       - "**/foo" now matches at the base of the transfer (like /foo
 2784:         does).  [Use "/**/foo" to get the old behavior in all versions.]
 2785: 
 2786:       - A non-anchored wildcard term floats to match beyond the base of
 2787:         the transfer.  E.g. "CVS/R*" matches at the end of the path,
 2788:         just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
 2789:         to get the old behavior in all versions.]
 2790: 
 2791:       - Including a "**" in the match term causes it to be matched
 2792:         against the entire path, not just the name portion, even if
 2793:         there aren't any interior slashes in the term.  E.g. "foo**bar"
 2794:         would exclude "/path/foo-bar" (just like before) as well as
 2795:         "/foo-path/baz-bar" (unlike before).  [Use "foo*bar" to get the
 2796:         old behavior in all versions.]
 2797: 
 2798:     * The exclude list specified in the daemon's config file is now
 2799:       properly applied to the pulled items no matter how deep the
 2800:       user's file-args are in the source tree.  (Wayne Davison)
 2801: 
 2802:     * For protocol version >= 27, mdfour_tail() is called when the
 2803:       block size (including checksum_seed) is a multiple of 64.
 2804:       Previously it was not called, giving the wrong MD4 checksum.
 2805:       (Craig Barratt)
 2806: 
 2807:     * For protocol version >= 27, a 64 bit bit counter is used in
 2808:       mdfour.c as required by the RFC.  Previously only a 32 bit bit
 2809:       counter was used, causing incorrect MD4 file checksums for
 2810:       file sizes >= 512MB - 4.  (Craig Barratt)
 2811: 
 2812:     * Fixed a crash bug when interacting with older rsync versions and
 2813:       multiple files of the same name are destined for the same dir.
 2814:       (Wayne Davison)
 2815: 
 2816:     * Keep tmp names from overflowing MAXPATHLEN.
 2817: 
 2818:     * Make --link-dest honor the absence of -p, -o, and -g.
 2819: 
 2820:     * Made rsync treat a trailing slash in the destination in a more
 2821:       consistent manner.
 2822: 
 2823:     * Fixed file I/O error detection.  (John Van Essen)
 2824: 
 2825:     * Fixed bogus "malformed address {hostname}" message in rsyncd log
 2826:       when checking IP address against hostnames from "hosts allow"
 2827:       and "hosts deny" parameters in config file.
 2828: 
 2829:     * Print heap statistics when verbose >= 2 instead of when >= 1.
 2830: 
 2831:     * Fixed a compression (-z) bug when syncing a mostly-matching file
 2832:       that contains already-compressed data.  (Yasuoka Masahiko and
 2833:       Wayne Davison)
 2834: 
 2835:     * Fixed a bug in the --backup code that could cause deleted files
 2836:       to not get backed up.
 2837: 
 2838:     * When the backup code makes new directories, create them with mode
 2839:       0700 instead of 0755 (since the directory permissions in the
 2840:       backup tree are not yet copied from the main tree).
 2841: 
 2842:     * Call setgroups() in a more portable manner.
 2843: 
 2844:     * Improved file-related error messages to better indicate exactly
 2845:       what pathname failed. (Wayne Davison)
 2846: 
 2847:     * Fixed some bugs in the handling of --delete and --exclude when
 2848:       using the --relative (-R) option. (Wayne Davison)
 2849: 
 2850:     * Fixed bug that prevented regular files from replacing
 2851:       special files and caused a directory in --link-dest or
 2852:       --compare-dest to block the creation of a file with the
 2853:       same path.  A directory still cannot be replaced by a
 2854:       regular file unless --delete specified.  (J.W. Schultz)
 2855: 
 2856:     * Detect and report when open or opendir succeed but read and
 2857:       readdir fail caused by network filesystem issues and truncated
 2858:       files.  (David Norwood, Michael Brown, J.W. Schultz)
 2859: 
 2860:     * Added a fix that should give ssh time to restore the tty settings
 2861:       if the user presses Ctrl-C at an ssh password prompt.
 2862: 
 2863:   INTERNAL:
 2864: 
 2865:     * Eliminated vestigial support for old versions that we stopped
 2866:       supporting. (J.W. Schultz)
 2867: 
 2868:     * Simplified some of the option-parsing code. (Wayne Davison)
 2869: 
 2870:     * Some cleanup made to the exclude code, as well as some new
 2871:       defines added to enhance readability. (Wayne Davison)
 2872: 
 2873:     * Changed the protocol-version code so that it can interact at a
 2874:       lower protocol level than the maximum supported by both sides.
 2875:       Added an undocumented option, --protocol=N, to force the value
 2876:       we advertise to the other side (primarily for testing purposes).

 2893: 
 2894:   ENHANCEMENTS:
 2895: 
 2896:     * The --delete-after option now implies --delete.  (Wayne Davison)
 2897: 
 2898:     * The --suffix option can now be used with --backup-dir.  (Michael
 2899:       Zimmerman)
 2900: 
 2901:     * Combining "::" syntax with the --rsh/-e option now uses the
 2902:       specified remote-shell as a transport to talk to a (newly-spawned)
 2903:       server-daemon.  This allows someone to use daemon features, such
 2904:       as modules, over a secure protocol, such as ssh.  (JD Paul)
 2905:

 2924: 
 2925:     * Changed exclude file handling to permit DOS or MAC style line

 2934:       L. Allen, Martin Pool)
 2935: 
 2936:     * Generate each file's rolling-checksum data as we send it, not

 3056:       CAN-2002-0059)
 3057: 
 3058:     * Fixed problem that in many cases caused the error message
 3059: 	unexpected read size of 0 in map_ptr
 3060:       and resulted in the wrong data being copied.
 3061: 
 3062:     * Fixed compilation errors on some systems caused by the use of

 3064: 
 3065:     * Fixed problem on systems such as Sunos4 that do not support realloc

 3080:     * Command to initiate connections is only shown with -vv, rather
 3081:       than -v as in 2.5.2.  Output from plain -v is more similar to
 3082:       what was historically used so as not to break scripts that try

 3084: 
 3085:     * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)

 3126:       visible and people will think it's faster.  (With --progress,
 3127:       rsync will show you how many files it has seen as it builds the

 3131:       but testing would be welcome.   (Jos Backus)

 3179: 
 3180:     * Martin Pool <mbp@samba.org> is now a co-maintainer.
 3181: 
 3182:   NEW FEATURES
 3183: 
 3184:     * Support for LSB-compliant packaging <http://www.linuxbase.org/>
 3185: 
 3186:     * Shell wildcards are allowed in "auth users" lines.
 3187: 
 3188:     * Merged UNC rsync+ patch to support creation of standalone patch
 3189:       sets.  By Bert J. Dempsey and Debra Weiss, updated by Jos
 3190:       Backus.  <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
 3191: 
 3192:     * IPv6 support based on a patch from KAME.net, on systems
 3193:       including modern versions of Linux, Solaris, and HP-UX.  Also
 3194:       includes IPv6 compatibility functions for old OSs by the
 3195:       Internet Software Consortium, Paul Vixie, the OpenSSH
 3196:       portability project, and OpenBSD.
 3197: 
 3198:   ENHANCEMENTS
 3199: 
 3200:     * Include/exclude cluestick: with -vv, print out whether files are
 3201:       included or excluded and why.
 3202: 
 3203:     * Many error messages have more friendly explanations and more
 3204:       details.
 3205: 
 3206:     * Manual page improvements plus scanty protocol documentation.
 3207: 
 3208:     * When running as --daemon in the background and using a "log
 3209:       file" rsyncd.conf directive, close the log file every time it is
 3210:       open when going to sleep on the socket.  This allows the log
 3211:       file to get cleaned out by another process.
 3212: 
 3213:     * Change to using libpopt rather than getopt for processing
 3214:       options.	This makes the code cleaner and the behaviour more
 3215:       consistent across platforms.  popt is included and built if not
 3216:       installed on the platform.
 3217: 
 3218:     * More details in --version, including note about whether 64-bit
 3219:       files, symlinks and hardlinks are supported.
 3220: 
 3221:     * MD4 code may use less CPU cycles.
 3222: 
 3223:     * Use mkstemp on systems where it is secure.  If we use mktemp,
 3224:       explain that we do it in a secure way.
 3225: 
 3226:     * --whole-file is the default when source and target are on the
 3227: 	local machine.
 3228: 
 3229:   BUG FIXES:
 3230: 
 3231:     * Fix for various bugs causing rsync to hang.
 3232: 
 3233:     * Attempt to fix Large File Summit support on AIX.
 3234: 
 3235:     * Attempt to fix error handling lockup bug.
 3236: 
 3237:     * Give a non-0 exit code if *any* of the files we have been asked
 3238:       to transfer fail to transfer.
 3239: 
 3240:     * For log messages containing ridiculously long strings that might
 3241:       overflow a buffer rsync no longer aborts, but rather prints an
 3242:       ellipsis at the end of the string.  (Patch from Ed Santiago.)
 3243: 
 3244:   PLATFORMS:
 3245: 
 3246:     * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
 3247:
