1 NEWS for rsync 3.0.6 (8 May 2009)
2 Protocol: 30 (unchanged)
7 - Fixed a --read-batch hang when rsync is reading a batch file that was
8 created from an incremental-recursion transfer.
10 - Fixed the daemon's socket code to handle the simultaneous arrival of
13 - Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
14 have consecutive slashes in the value.
16 - Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
18 - The sender now skips a (bogus) symlink that has a 0-length value, which
19 avoids a transfer error in the receiver.
21 - Fixed a case where the sender could die with a tag-0 error if there was
22 an I/O during the sending of the file list.
24 - Fixed the rrsync script to avoid a server-side problem when -e is at the
25 start of the short options.
27 - Fixed a problem where a vanished directory could turn into an exit code
28 23 instead of the proper exit code 24.
30 - Fixed the --iconv conversion of symlinks when doing a local copy.
32 - Fixed a problem where --one-file-system was not stopping deletions on the
33 receiving side when a mount-point directory did not match a directory in
36 - Fixed the dropping of an ACL mask when no named ACL values were present.
38 - Fixed an ACL/xattr corruption issue where the --backup option could cause
39 rsync to associate the wrong ACL/xattr information with received files.
41 - Fixed the use of --xattrs with --only-write-batch.
43 - Fixed the use of --dry-run with --read-batch.
45 - Fixed configure's erroneous use of target.
47 - Fixed configure's --disable-debug option.
49 - Fixed a run-time issue for systems that can't find iconv_open() by adding
50 the --disable-iconv-open configure option.
52 - Complain and die if the user tries to combine --remove-source-files (or
53 the deprecated --remove-sent-files) with --read-batch.
55 - Fixed an failure transferring special files from Solaris to Linux.
58 NEWS for rsync 3.0.5 (28 Dec 2008)
59 Protocol: 30 (unchanged)
64 - Initialize xattr data in a couple spots in the hlink code, which avoids a
65 crash when the xattr pointer's memory happens to start out non-zero.
66 Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
68 - Don't send a bogus "-" option to an older server if there were no short
71 - Fixed skipping of unneeded updates in a batch file when incremental
72 recursion is active. Added a test for this. Made batch-mode handle
73 "redo" files properly (and without hanging).
75 - Fix the %P logfile escape when the daemon logs from inside a chroot.
77 - Fixed the use of -s (--protect-args) when used with a remote source or
78 destination that had an empty path (e.g. "host:"). Also fixed a problem
79 when -s was used when accessing a daemon via a remote-shell.
81 - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from
82 file when the root of the transfer isn't the current directory.
84 - Fixed a bug with "-K --delete" removing symlinks to directories when
85 incremental recursion is active.
87 - Fixed a hard to trigger hang when using --remove-source-files.
89 - Got rid of an annoying delay when accessing a daemon via a remote-shell.
91 - Properly ignore (superfluous) source args on a --read-batch command.
93 - Improved the manpage's description of the '*' wildcard to remove the
94 confusing "non-empty" qualifier.
96 - Fixed reverse lookups in the compatibility-library version of
99 - Fixed a bug when using --sparse on a sparse file that has over 2GB of
100 consecutive sparse data.
102 - Avoid a hang when using at least 3 --verbose options on a transfer with a
103 client sender (which includes local copying).
105 - Fixed a problem with --delete-delay reporting an error when it was ready
106 to remove a directory that was now gone.
108 - Got rid of a bunch of "warn_unused_result" compiler warnings.
110 - If an ftruncate() on a received file fails, it now causes a partial-
113 - Allow a path with a leading "//" to be preserved (CYGWIN only).
117 - Made the support/atomic-rsync script able to perform a fully atomic
118 update of the copied hierarchy when the destination is setup using a
119 particular symlink idiom.
122 NEWS for rsync 3.0.4 (6 Sep 2008)
123 Protocol: 30 (unchanged)
128 - Fixed a bug in the hard-linking code where it would sometimes try to
129 allocate 0 bytes of memory (which fails on some OSes, such as AIX).
131 - Fixed the hard-linking of files from a device that has a device number
132 of 0 (which seems to be a common device number on NetBSD).
134 - Fixed the handling of a --partial-dir that cannot be created. This
135 particularly impacts the --delay-updates option (since the files cannot
136 be delayed without a partial-dir), and was potentially destructive if
137 the --remove-source-files was also specified.
139 - Fixed a couple issues in the --fake-super handling of xattrs when the
140 destination files have root-level attributes (e.g. selinux values) that
141 a non-root copy can't affect.
143 - Improved the keep-alive check in the generator to fire consistently in
144 incremental-recursion mode when --timeout is enabled.
146 - The --iconv option now converts the content of a symlink too, instead
147 of leaving it in the wrong character-set (requires 3.0.4 on both sides
150 - When using --iconv, if a filename fails to convert on the receiving side,
151 this no longer makes deletions in the root-dir of the transfer fail
152 silently (the user now gets a warning about deletions being disabled
153 due to IO error as long as --ignore-errors was not specified).
155 - When using --iconv, if a server-side receiver can't convert a filename,
156 the error message sent back to the client no longer mangles the name
157 with the wrong charset conversion.
159 - Fixed a potential alignment issue in the IRIX ACL code when allocating
160 the initial "struct acl" object. Also, cast mallocs to avoid warnings.
162 - Changed some errors that were going to stdout to go to stderr.
164 - Made human_num() and human_dnum() able to output a negative number
165 (rather than outputting a cryptic string of punctuation).
169 - Rsync will avoid sending an -e option to the server if an older protocol
170 is requested (and thus the option would not be useful). This lets the
171 user specify the --protocol=29 option to access an overly-restrictive
172 server that is rejecting the protocol-30 use of -e to the server.
174 - Improved the message output for an RERR_PARTIAL exit.
178 - The Makefile will not halt for just a timestamp change on the Makefile
179 or the configure files, only for actual changes in content.
181 - Changed some commands in the testsuite's xattrs.test that called "rsync"
184 - Enhanced the release scripts to be able to handle a branch release and
185 to do even more consistency checks on the files.
188 NEWS for rsync 3.0.3 (29 Jun 2008)
189 Protocol: 30 (unchanged)
194 - Fixed a wildcard matching problem in the daemon when a module has
195 "use chroot" enabled.
197 - Fixed a crash bug in the hard-link code.
199 - Fixed the sending of xattr directory information when the code finds a
200 --link-dest or --copy-dest directory with unchanged xattrs -- the
201 destination directory now gets these unchanged xattrs properly applied.
203 - Fixed an xattr-sending glitch that could cause an "Internal abbrev"
206 - Fixed the combination of --xattrs and --backup.
208 - The generator no longer allows a '.' dir to be excluded by a daemon-
211 - Fixed deletion handling when copying a single, empty directory (with no
212 files) to a differently named, non-existent directory.
214 - Fixed the conversion of spaces into dashes in the %M log escape.
216 - Fixed several places in the code that were not returning the right
217 errno when a function failed.
219 - Fixed the backing up of a device or special file into a backup dir.
221 - Moved the setting of the socket options prior to the connect().
223 - If rsync exits in the middle of a --progress output, it now outputs a
224 newline to help prevent the progress line from being overwritten.
226 - Fixed a problem with how a destination path with a trailing slash or
227 a trailing dot-dir was compared against the daemon excludes.
229 - Fixed the sending of large (size > 16GB) files when talking to an older
230 rsync (protocols < 30): we now use a compatible block size limit.
232 - If a file's length is so huge that we overflow a checksum buffer count
233 (i.e. several hundred TB), warn the user and avoid sending an invalid
234 checksum struct over the wire.
236 - If a source arg is excluded, --relative no longer adds the excluded
237 arg's implied dirs to the transfer. This fix also made the exclude
238 check happen in the better place in the sending code.
240 - Use the overflow_exit() function for overflows, not out_of_memory().
242 - Improved the code to better handle a system that has only 32-bit file
247 - The rsyncd.conf manpage now consistently refers to the parameters in
248 the daemon config file as "parameters".
250 - The description of the --inplace option was improved.
254 - Added a new script in the support directory, deny-rsync, which allows
255 an admin to (temporarily) replace the rsync command with a script that
256 sends an error message to the remote client via the rsync protocol.
260 - Fixed a testcase failure if the tests are run as root and made some
261 compatibility improvements.
263 - Improved the daemon tests, including checking module comments, the
264 listing of files, and the ensuring that daemon excludes can't affect
267 - Improved some build rules for those that build in a separate directory
268 from the source, including better install rules for the man pages, and
269 the fixing of a proto.h-tstamp rule that could make the binaries get
270 rebuild without cause.
272 - Improved the testsuite to work around a problem with some utilities
273 (e.g. cp -p & touch -r) rounding sub-second timestamps.
275 - Ensure that the early patches don't cause any generated-file hunks to
276 bleed-over into patches that follow.
279 NEWS for rsync 3.0.2 (8 Apr 2008)
280 Protocol: 30 (unchanged)
285 - Fixed a potential buffer overflow in the xattr code.
293 - The RPM spec file was improved to install more useful files.
295 - A few developer-oriented scripts were moved from the support dir
296 to the packaging dir.
299 NEWS for rsync 3.0.1 (3 Apr 2008)
300 Protocol: 30 (unchanged)
303 NOTABLE CHANGES IN BEHAVIOR:
305 - Added the 'c'-flag to the itemizing of non-regular files so that the
306 itemized output doesn't get hidden if there were no attribute changes,
307 and also so that the itemizing of a --copy-links run will distinguish
308 between copying an identical non-regular file and the creation of a
309 revised version with a new value (e.g. a changed symlink referent, a
310 new device number, etc.).
314 - Fixed a crash bug when a single-use rsync daemon (via remote shell) was
315 run without specifying a --config=FILE option.
317 - Fixed a crash when backing up a directory that has a default ACL.
319 - Fixed a bug in the handling of xattr values that could cause rsync to
320 not think that a file's extended attributes are up-to-date.
322 - Fixed the working of --fake-super with --link-dest and --xattrs.
324 - Fixed a hang when combining --dry-run with --remove-source-files.
326 - Fixed a bug with --iconv's handling of files that cannot be converted:
327 a failed name can no longer cause a transfer failure.
329 - Fixed the building of the rounding.h file on systems that need custom
330 CPPFLAGS to be used. Also improved the error reporting if the building
333 - Fixed the use of the --protect-args (-s) option when talking to a daemon.
335 - Fixed the --ignore-existing option's protection of files on the receiver
336 that are non-regular files on the sender (e.g. if a symlink or a dir on
337 the sender is trying to replace a file on the receiver). The reverse
338 protection (protecting a dir/symlink/device from being replaced by a
339 file) was already working.
341 - Fixed an assert failure if --hard-links is combined with an option that
342 can skip a file in a set of hard-linked files (i.e. --ignore-existing,
343 --append, etc.), without skipping all the files in the set.
345 - Avoid setting the modify time on a directory that already has the right
346 modify time set. This avoids tweaking the dir's ctime.
348 - Improved the daemon-exclude handling to do a better job of applying the
349 exclude rules to path entries. It also sends the user an error just as
350 if the files were actually missing (instead of silently ignoring the
351 user's args), and avoids sending the user the filter-action messages
352 for these non-user-initiated rules.
354 - Fixed some glitches with the dry-run code's missing-directory
355 handling, including a problem when combined with --fuzzy.
357 - Fixed some glitches with the skipped-directory handling.
359 - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
361 - Fixed a glitch in the itemizing of permissions with the -E option.
363 - The --append option's restricting of transfers to those that add data no
364 longer prevents the updating of non-content changes to otherwise up-to-
365 date files (i.e. those with the same content but differing permissions,
366 ownership, xattrs, etc.).
368 - Don't allow --fake-super to be specified with -XX (double --xattrs)
369 because the options conflict. If a daemon has "fake super" enabled,
370 it automatically downgrades a -XX request to -X.
372 - Fixed a couple bugs in the parsing of daemon-config excludes that could
373 make a floating exclude rule get treated as matching an absolute path.
375 - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
376 wasn't compiled in to the daemon (avoiding a warning in the logs).
378 - Fixed the inclusion of per-dir merge files from implied dirs.
380 - Fixed the support/rrsync script to work with the latest options that
381 rsync sends (including its flag-specifying use of -e to the server).
385 - Added the --old-dirs (--old-d) option to make it easier for a user to
386 ask for file-listings with older rsync versions (this is easier than
387 having to type "-r --exclude='/*/*'" manually).
389 - When getting an error while asking an older rsync daemon for a file
390 listing, rsync will try to notice if the error is a rejection of the
391 --dirs (-d) option and let the user know how to work around the issue.
393 - Added a few more --no-OPTION overrides.
395 - Improved the documentation of the --append option.
397 - Improved the documentation of the filter/exclude/include daemon
402 - Fixed a couple minor bugs in the included popt library (ones which I
403 sent to the official popt project for inclusion in the 1.14 release).
405 - Fixed a stat() call that should have been do_stat() so that the proper
406 normal/64-bit stat() function gets called. (Was in an area that should
407 not have caused problems, though.)
409 - Changed the file-glob code to do a directory scan without using the
410 "glob" and "glob.h". This lets us do the globbing with less memory
411 churn, and also avoid adding daemon-excluded items to the returned
416 - The configure script tries to get the user's compiler to not warn about
417 unused function parameters if the build is not including one or more of
418 the ACL/xattrs/iconv features.
420 - The configure script now has better checks for figuring out if the
421 included popt code should be used or not.
423 - Fixed two testsuite glitches: avoid a failure if someone's "cd" command
424 outputs the current directory when cd-ing to a relative path, and made
425 the itemized test query how rsync was built to determine if it should
426 expect hard-linked symlinks or not.
428 - Updated the testsuite to verify that various bug fixes remain fixed.
430 - The RPM spec file was updated to have: (1) comments for how to use the
431 rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
433 - Updated the build scripts to work with a revised FTP directory
437 NEWS for rsync 3.0.0 (1 Mar 2008)
438 Protocol: 30 (changed)
441 NOTABLE CHANGES IN BEHAVIOR:
443 - The handling of implied directories when using --relative has changed to
444 send them as directories (e.g. no implied dir is ever sent as a symlink).
445 This avoids unexpected behavior and should not adversely affect most
446 people. If you're one of those rare individuals who relied upon having
447 an implied dir be duplicated as a symlink, you should specify the
448 transfer of the symlink and the transfer of the referent directory as
449 separate args. (See also --keep-dirlinks and --no-implied-dirs.)
450 Also, exclude rules no longer have a partial effect on implied dirs.
452 - Requesting a remote file-listing without specifying -r (--recursive) now
453 sends the -d (--dirs) option to the remote rsync rather than sending -r
454 along with an extra exclude of /*/*. If the remote rsync does not
455 understand the -d option (i.e. it is 2.6.3 or older), you will need to
456 either turn off -d (--no-d), or specify -r --exclude='/*/*' manually.
458 - In --dry-run mode, the last line of the verbose summary text is output
459 with a "(DRY RUN)" suffix to help remind you that no updates were made.
460 Similarly, --only-write-batch outputs "(BATCH ONLY)".
462 - A writable rsync daemon with "use chroot" disabled now defaults to a
463 symlink-munging behavior designed to make symlinks safer while also
464 allowing absolute symlinks to be stored and retrieved. This also has
465 the effect of making symlinks unusable while they're in the daemon's
466 hierarchy. See the daemon's "munge symlinks" parameter for details.
468 - Starting up an extra copy of an rsync daemon will not clobber the pidfile
469 for the running daemon -- if the pidfile exists, the new daemon will exit
470 with an error. This means that your wrapper script that starts the rsync
471 daemon should be made to handle lock-breaking (if you want any automatic
472 breaking of locks to be done).
476 - A daemon with "use chroot = no" and excluded items listed in the daemon
477 config file now properly checks an absolute-path arg specified for these
478 options: --compare-dest, --link-dest, --copy-dest, --partial-dir,
479 --backup-dir, --temp-dir, and --files-from.
481 - A daemon can now be told to disable all user- and group-name translation
482 on a per-module basis. This avoids a potential problem with a writable
483 daemon module that has "use chroot" enabled -- if precautions weren't
484 taken, a user could try to add a missing library and get rsync to use
485 it. This makes rsync safer by default, and more configurable when id-
486 translation is not desired. See the daemon's "numeric ids" parameter
489 - A chroot daemon can now indicate which part of its path should affect the
490 chroot call, and which part should become an inside-chroot path for the
491 module. This allows you to have outside-the-transfer paths (such as for
492 libraries) even when you enable chroot protection. The idiom used in the
493 rsyncd.conf file is: path = /chroot/dirs/./dirs/inside
495 - If a file's data arrived successfully on the receiving side but the
496 rename of the temporary file to the destination file failed AND the
497 --remove-source-files (or the deprecated --remove-sent-files) option
498 was specified, rsync no longer erroneously removes the associated
501 - Fixed the output of -ii when combined with one of the --*-dest options:
502 it now itemizes all the items, not just the changed ones.
504 - Made the output of all file types consistent when using a --*-dest
505 option. Prior versions would output too many creation events for
508 - The code that waits for a child pid now handles being interrupted by a
509 signal. This fixes a problem with the pre-xfer exec function not being
510 able to get the exit status from the script.
512 - A negated filter rule (i.e. with a '!' modifier) no longer loses the
513 negation when sending the filter rules to the remote rsync.
515 - Fixed a problem with the --out-format (aka --log-format) option %f: it
516 no longer outputs superfluous directory info for a non-daemon rsync.
518 - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
519 files (which includes local copies). Version 2.6.9 would complete the
520 copy, but exit with an error when the receiver output its memory stats.
522 - If --password-file is used on a non-daemon transfer, rsync now complains
523 and exits. This should help users figure out that they can't use this
524 option to control a remote shell's password prompt.
526 - Make sure that directory permissions of a newly-created destination
527 directory are handled right when --perms is left off.
529 - The itemized output of a newly-created destination directory is now
530 output as a creation event, not a change event.
532 - Improved --hard-link so that more corner cases are handled correctly
533 when combined with options such as --link-dest and/or --ignore-existing.
535 - The --append option no longer updates a file that has the same size.
537 - Fixed a bug when combining --backup and --backup-dir with --inplace:
538 any missing backup directories are now created.
540 - Fixed a bug when using --backup and --inplace with --whole-file or
541 --read-batch: backup files are actually created now.
543 - The daemon pidfile is checked and created sooner in the startup sequence.
545 - If a daemon module's "path" value is not an absolute pathname, the code
546 now makes it absolute internally (making it work properly).
548 - Ensure that a temporary file always has owner-write permission while we
549 are writing to it. This avoids problems with some network filesystems
550 when transfering read-only files.
552 - Any errors output about password-file reading no longer cause an error at
553 the end of the run about a partial transfer.
555 - The --read-batch option for protocol 30 now ensures that several more
556 options are set correctly for the current batch file: --iconv, --acls,
557 --xattrs, --inplace, --append, and --append-verify.
559 - Using --only-write-batch to a daemon receiver now works properly (older
560 versions would update some files while writing the batch).
562 - Avoid outputting a "file has vanished" message when the file is a broken
563 symlink and --copy-unsafe-links or --copy-dirlinks is used (the code
564 already handled this for --copy-links).
566 - Fixed the combination of --only-write-batch and --dry-run.
568 - Fixed rsync's ability to remove files that are not writable by the file's
569 owner when rsync is running as the same user.
571 - When transferring large files, the sender's hashtable of checksums is
572 kept at a more reasonable state of fullness (no more than 80% full) so
573 that the scanning of the hashtable will not bog down as the number of
578 - A new incremental-recursion algorithm is now used when rsync is talking
579 to another 3.x version. This starts the transfer going more quickly
580 (before all the files have been found), and requires much less memory.
581 See the --recursive option in the manpage for some restrictions.
583 - Lowered memory use in the non-incremental-recursion algorithm for typical
584 option values (usually saving from 21-29 bytes per file).
586 - The default --delete algorithm is now --delete-during when talking to a
587 3.x rsync. This is a faster scan than using --delete-before (which is
588 the default when talking to older rsync versions), and is compatible with
589 the new incremental recursion mode.
591 - Rsync now allows multiple remote-source args to be specified rather than
592 having to rely on a special space-splitting side-effect of the remote-
593 shell. Additional remote args must specify the same host or an empty one
594 (e.g. empty: :file1 or ::module/file2). For example, this means that
595 local use of brace expansion now works: rsync -av host:dir/{f1,f2} .
597 - Added the --protect-args (-s) option, that tells rsync to send most of
598 the command-line args at the start of the transfer rather than as args
599 to the remote-shell command. This protects them from space-splitting,
600 and only interprets basic wildcard special shell characters (*?[).
602 - Added the --delete-delay option, which is a more efficient way to delete
603 files at the end of the transfer without needing a separate delete pass.
605 - Added the --acls (-A) option to preserve Access Control Lists. This is
606 an improved version of the prior patch that was available, and it even
607 supports OS X ACLs. If you need to have backward compatibility with old,
608 ACL-patched versions of rsync, apply the acls.diff file from the patches
611 - Added the --xattrs (-X) option to preserve extended attributes. This is
612 an improved version of the prior patch that was available, and it even
613 supports OS X xattrs (which includes their resource fork data). If you
614 need to have backward compatibility with old, xattr-patched versions of
615 rsync, apply the xattrs.diff file from the patches dir.
617 - Added the --fake-super option that allows a non-super user to preserve
618 all attributes of a file by using a special extended-attribute idiom.
619 It even supports the storing of foreign ACL data on your backup server.
620 There is also an analogous "fake super" parameter for an rsync daemon.
622 - Added the --iconv option, which allows rsync to convert filenames from
623 one character-set to another during the transfer. The default is to
624 make this feature available as long as your system has iconv_open().
625 If compilation fails, specify --disable-iconv to configure, and then
626 rebuild. If you want rsync to perform character-set conversions by
627 default, you can specify --enable-iconv=CONVERT_STRING with the default
628 value for the --iconv option that you wish to use. For example,
629 "--enable-iconv=." is a good choice. See the rsync manpage for an
630 explanation of the --iconv option's settings.
632 - A new daemon config parameter, "charset", lets you control the character-
633 set that is used during an --iconv transfer to/from a daemon module. You
634 can also set your daemon to refuse "no-iconv" if you want to force the
635 client to use an --iconv transfer (requiring an rsync 3.x client).
637 - Added the --skip-compress=LIST option to override the default list of
638 file suffixes that will not be compressed when using --compress (-z).
640 - The daemon's default for "dont compress" was extended to include:
641 *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
642 The name-matching routine was also optimized to run more quickly.
644 - The --max-delete option now outputs a warning if it skipped any file
645 deletions, including a count of how many deletions were skipped. (Older
646 versions just silently stopped deleting things.)
648 - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
649 about extraneous files without deleting anything. If you're not sure
650 what version the client is, you can use the less-obvious --max-delete=-1,
651 as both old and new versions will treat that as the same request (though
652 older versions don't warn).
654 - The --hard-link option now uses less memory on both the sending and
655 receiving side for all protocol versions. For protocol 30, the use of a
656 hashtable on the sending side allows us to more efficiently convey to the
657 receiver what files are linked together. This reduces the amount of data
658 sent over the socket by a considerable margin (rather than adding more
659 data), and limits the in-memory storage of the device+inode information
660 to just the sending side for the new protocol 30, or to the receiving
661 side when speaking an older protocol (note that older rsync versions kept
662 the device+inode information on both sides).
664 - The filter rules now support a perishable ("p") modifier that marks rules
665 that should not have an effect in a directory that is being deleted. e.g.
666 -f '-p .svn/' would only affect "live" .svn directories.
668 - Rsync checks all the alternate-destination args for validity (e.g.
669 --link-dest). This lets the user know when they specified a directory
672 - If we get an ENOSYS error setting the time on a symlink, we don't
673 complain about it anymore (for those systems that even support the
674 setting of the modify-time on a symlink).
676 - Protocol 30 now uses MD5 checksums instead of MD4.
678 - Changed the --append option to not checksum the existing data in the
679 destination file, which speeds up file appending.
681 - Added the --append-verify option, which works like the older --append
682 option (verifying the existing data in the destination file). For
683 compatibility with older rsync versions, any use of --append that is
684 talking protocol 29 or older will revert to the --append-verify method.
686 - Added the --contimeout=SECONDS option that lets the user specify a
687 connection timeout for rsync daemon access.
689 - Documented and extended the support for the RSYNC_CONNECT_PROG variable
690 that can be used to enhance the client side of a daemon connection.
692 - Improved the dashes and double-quotes in the nroff manpage output.
694 - Rsync now supports a lot more --no-OPTION override options.
698 - The file-list sorting algorithm now uses a sort that keeps any same-
699 named items in the same order as they were specified. This allows
700 rsync to always ensure that the first of the duplicates is the one
701 that will be included in the copy. The new sort is also faster
702 than the glibc version of qsort() and mergesort().
704 - Rsync now supports the transfer of 64-bit timestamps (time_t values).
706 - Made the file-deletion code use a little less stack when recursing
707 through a directory hierarchy of extraneous files.
709 - Fixed a build problem with older (2.x) versions of gcc.
711 - Added some isType() functions that make dealing with signed characters
712 easier without forcing variables via casts.
714 - Changed strcat/strcpy/sprintf function calls to use safer versions.
716 - Upgraded the included popt version to 1.10.2 and improved its use of
717 string-handling functions.
719 - Added missing prototypes for compatibility functions from the lib dir.
721 - Configure determines if iconv() has a const arg, allowing us to avoid a
724 - Made the sending of some numbers more efficient for protocol 30.
726 - Make sure that a daemon process doesn't mind if the client was weird and
727 omitted the --server option.
729 - There are more internal logging categories available in protocol 30 than
730 the age-old FINFO and FERROR, including FERROR_XFER and FWARN. These new
731 categories allow some errors and warnings to go to stderr without causing
732 an erroneous end-of-run warning about some files not being able to be
735 - Improved the use of "const" on pointers.
737 - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
738 older sections of a pool's memory.
740 - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
741 some new code (derived from samba, derived from PostgreSQL) that has a
742 better license than the old code.
746 - Rsync is now licensed under the GPLv3 or later.
748 - Rsync is now being maintained in a "git" repository instead of CVS
749 (though the old CVS repository still exists for historical access).
750 Several maintenance scripts were updated to work with git.
752 - Generated files are no longer committed into the source repository. The
753 autoconf and autoheader commands are now automatically run during the
754 normal use of "configure" and "make". The latest dev versions of all
755 generated files can also be copied from the samba.org web site (see the
756 prepare-source script's fetch option).
758 - The "patches" directory of diff files is now built from branches in the
759 rsync git repository (branch patch/FOO creates file patches/FOO.diff).
760 This directory is now distributed in a separate separate tar file named
761 rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
763 - The proto.h file is now built using a simple perl script rather than a
764 complex awk script, which proved to be more widely compatible.
766 - When running the tests, we now put our per-test temp dirs into a sub-
767 directory named testtmp (which is created, if missing). This allows
768 someone to symlink the testtmp directory to another filesystem (which is
769 useful if the build dir's filesystem does not support ACLs and xattrs,
770 but another filesystem does).
772 - Rsync now has a way of handling protocol-version changes during the
773 development of a new protocol version. This causes any out-of-sync
774 versions to speak an older protocol rather than fail in a cryptic manner.
775 This addition makes it safer to deploy a pre-release version that may
776 interact with the public. This new exchange of sub-version info does not
777 interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
778 does not have enough range to allow the main protocol number to be
779 incremented for every minor tweak in that happens during development).
781 - The csprotocol.txt file was updated to mention the daemon protocol change
782 in the 3.0.0 release.
785 NEWS for rsync 2.6.9 (6 Nov 2006)
786 Protocol: 29 (unchanged)
791 - If rsync is interrupted via a handled signal (such as SIGINT), it will
792 once again clean-up its temp file from the destination dir.
794 - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
795 --copy-dest, and --compare-dest options to a daemon without chroot: if
796 the copy's destination dir is deeper than the top of the module's path,
797 these options now accept a safe number of parent-dir (../) references
798 (since these options are relative to the destination dir). The old code
799 incorrectly chopped off all "../" prefixes for these options, no matter
800 how deep the destination directory was in the module's hierarchy.
802 - Fixed a bug where a deferred info/error/log message could get sent
803 directly to the sender instead of being handled by rwrite() in the
804 generator. This fixes an "unexpected tag 3" fatal error, and should
805 also fix a potential problem where a deferred info/error message from
806 the receiver might bypass the log file and get sent only to the client
807 process. (These problems could only affect an rsync daemon that was
810 - Fixed a bug when --inplace was combined with a --*-dest option and we
811 update a file's data using an alternate basis file. The code now
812 notices that it needs to copy the matching data from the basis file
813 instead of (wrongly) assuming that it was already present in the file.
815 - Fixed a bug where using --dry-run with a --*-dest option with a path
816 relative to a directory that does not yet exist: the affected option
817 gets its proper path value so that the output of the dry-run is right.
819 - Fixed a bug in the %f logfile escape when receiving files: the
820 destination path is now included in the output (e.g. you can now tell
821 when a user specifies a subdir inside a module).
823 - If the receiving side fails to create a directory, it will now skip
824 trying to update everything that is inside that directory.
826 - If --link-dest is specified with --checksum but without --times, rsync
827 will now allow a hard-link to be created to a matching link-dest file
828 even when the file's modify-time doesn't match the server's file.
830 - The daemon now calls more timezone-using functions prior to doing a
831 chroot. This should help some C libraries to generate proper timestamps
832 from inside a chrooted daemon (and to not try to access /etc/timezone
833 over and over again).
835 - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
836 it now deletes an alternate basis file from the partial-dir that was used
837 to successfully update a destination file.
839 - Fixed a bug in the handling of --delete-excluded when using a per-dir
840 merge file: the merge file is now honored on the receiving side, and
841 only its unqualified include/exclude commands are ignored (just as is
842 done for global include/excludes).
844 - Fixed a recent bug where --delete was not working when transferring from
845 the root (/) of the filesystem with --relative enabled.
847 - Fixed a recent bug where an --exclude='*' could affect the root (/) of
848 the filesystem with --relative enabled.
850 - When --inplace creates a file, it is now created with owner read/write
851 permissions (0600) instead of no permissions at all. This avoids a
852 problem continuing a transfer that was interrupted (since --inplace
853 will not update a file that has no write permissions).
855 - If either --remove-source-files or --remove-sent-files is enabled and we
856 are unable to remove the source file, rsync now outputs an error.
858 - Fixed a bug in the daemon's "incoming chmod" rule: newly-created
859 directories no longer get the 'F' (file) rules applied to them.
861 - Fixed an infinite loop bug when a filter rule was rejected due to being
864 - When the server receives a --partial-dir option from the client, it no
865 longer runs the client-side code that adds an assumed filter rule (since
866 the client will be sending us the rules in the usual manner, and they
867 may have chosen to override the auto-added rule).
871 - Added the --log-file=FILE and --log-file-format=FORMAT options. These
872 can be used to tell any rsync to output what it is doing to a log file.
873 They work with a client rsync, a non-daemon server rsync (see the man
874 page for instructions), and also allows the overriding of rsyncd.conf
875 settings when starting a daemon.
877 - The --log-format option was renamed to be --out-format to avoid confusing
878 it with affecting the log-file output. (The old option remains as an
879 alias for the new to preserve backward compatibility.)
881 - Made "log file" and "syslog facility" settable on a per-module basis in
882 the daemon's config file.
884 - Added the --remove-source-files option as a replacement for the (now
885 deprecated) --remove-sent-files option. This new option removes all
886 non-dirs from the source directories, even if the file was already
887 up-to-date. This fixes a problem where interrupting an rsync that
888 was using --remove-sent-files and restarting it could leave behind
889 a file that the earlier rsync synchronized, but didn't get to remove.
890 (The deprecated --remove-sent-files is still understood for now, and
891 still behaves in the same way as before.)
893 - Added the option --no-motd to suppress the message-of-the-day output
894 from a daemon when doing a copy. (See the manpage for a caveat.)
896 - Added a new environment variable to the pre-/post-xfer exec commands (in
897 the daemon's config file): RSYNC_PID. This value will be the same in
898 both the pre- and post-xfer commands, so it can be used as a unique ID
899 if the pre-xfer command wants to cache some arg/request info for the
904 - Did a code audit using IBM's code-checker program and made several
905 changes, including: replacing most of the strcpy() and sprintf()
906 calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
907 an enum that had been intermingling a literal 0 with the defined enum
908 values, silencing some uninitialized memory checks, marking some
909 functions with a "noreturn" attribute, and changing an "if" that
910 could never succeed on some platforms into a pre-processor directive
911 that conditionally compiles the code.
913 - Fixed a potential bug in f_name_cmp() when both the args are a
914 top-level "." dir (which doesn't happen in normal operations).
916 - Changed exit_cleanup() so that it can never return instead of exit.
917 The old code might return if it found the exit_cleanup() function
918 was being called recursively. The new code is segmented so that
919 any recursive calls move on to the next step of the exit-processing.
921 - The macro WIFEXITED(stat) will now be defined if the OS didn't already
926 - The acls.diff and xattrs.diff patches have received a bunch of work to
927 make them much closer to being acceptable in the main distribution.
928 The xattrs patch also has some preliminary Mac OS X and FreeBSD
929 compatibility code that various system types to exchange extended
932 - A new diff in the patches dir, fake-root.diff, allows rsync to
933 maintain a backup hierarchy with full owner, group, and device info
934 without actually running as root. It does this using a special
935 extended attribute, so it depends on xattrs.diff (which depends on
938 - The rsync.yo and rsyncd.conf.yo files have been updated to work
939 better with the latest yodl 2.x releases.
941 - Updated config.guess and config.sub to their 2006-07-02 versions.
943 - Updated various files to include the latest FSF address and to have
944 consistent opening comments.
947 NEWS for rsync 2.6.8 (22 Apr 2006)
948 Protocol: 29 (unchanged)
953 - Fixed a bug in the exclude code where an anchored exclude without any
954 wildcards fails to match an absolute source arg, but only when --relative
957 - Improved the I/O code for the generator to fix a potential hang when the
958 receiver gets an EOF on the socket but the generator's select() call
959 never indicates that the socket is writable for it to be notified about
960 the EOF. (This can happen when using stunnel).
962 - Fixed a problem with the file-reading code where a failed read (such as
963 that caused by a bad sector) would not advance the file's read-position
964 beyond the failed read's data.
966 - Fixed a logging bug where the "log file" directive was not being honored
967 in a single-use daemon (one spawned by a remote-shell connection or by
970 - If rsync cannot honor the --delete option, we output an error and exit
971 instead of silently ignoring the option.
973 - Fixed a bug in the --link-dest code that prevented special files (such as
974 fifos) from being linked.
976 - The ability to hard-link symlinks and special files is now determined at
977 configure time instead of at runtime. This fixes a bug with --link-dest
978 creating a hard-link to a symlink's referent on a BSD system.
982 - In daemon mode, if rsync fails to bind to the requested port, the
983 error(s) returned by socket() and/or bind() are now logged.
985 - When we output a fatal error, we now output the version of rsync in the
988 - Improved the documentation for the --owner and --group options.
990 - The rsyncstats script in "support" has an improved line-parsing regex
991 that is easier to read and also makes it to parse syslog-generated lines.
993 - A new script in "support": file-attr-restore, can be used to restore the
994 attributes of a file-set (the permissions, ownership, and group info)
995 taken from the cached output of a "find ARG... -ls" command.
999 - Removed the unused function write_int_named(), the unused variable
1000 io_read_phase, and the rarely used variable io_write_phase. This also
1001 elides the confusing 'phase "unknown"' part of one error message.
1003 - Removed two unused configure checks and two related (also unused)
1004 compatibility functions.
1006 - The xattrs.diff patch received a security fix that prevents a potential
1007 buffer overflow in the receive_xattr() code.
1009 - The acls.diff patch has been improved quite a bit, with more to come.
1011 - A new patch was added: log-file.diff. This contains an early version of
1012 a future option, --log-file=FILE, that will allow any rsync to log its
1013 actions to a file (something that only a daemon supports at present).
1016 NEWS for rsync 2.6.7 (11 Mar 2006)
1017 Protocol: 29 (unchanged)
1018 Changes since 2.6.6:
1022 - The letter 'D' in the itemized output was being used for both devices
1023 (character or block) as well as other special files (such as fifos and
1024 named sockets). This has changed to separate non-device special files
1025 under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the
1026 "--specials" option, below.
1028 - The way rsync escapes unreadable characters has changed. First, rsync
1029 now has support for recognizing valid multibyte character sequences in
1030 your current locale, allowing it to escape fewer characters than before
1031 for a locale such as UTF-8. Second, it now uses an escape idiom of
1032 "\#123", which is the literal string "\#" followed by exactly 3 octal
1033 digits. Rsync no longer doubles a backslash character in a filename
1034 (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
1035 escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
1036 (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also
1037 the --8-bit-output (-8) option, mentioned below.
1039 Script writers: the local rsync is the one that outputs escaped names,
1040 so if you need to support unescaping of filenames for older rsyncs, I'd
1041 suggest that you parse the output of "rsync --version" and only use the
1042 old unescaping rules for 2.6.5 and 2.6.6.
1046 - Fixed a really old bug that caused --checksum (-c) to checksum all the
1047 files encountered during the delete scan (ouch).
1049 - Fixed a potential hang in a remote generator: when the receiver gets a
1050 read-error on the socket, it now signals the generator about this so that
1051 the generator does not try to send any of the terminating error messages
1052 to the client (avoiding a potential hang in some setups).
1054 - Made hard-links work with symlinks and devices again.
1056 - If the sender gets an early EOF reading a source file, we propagate this
1057 error to the receiver so that it can discard the file and try requesting
1058 it again (which is the existing behavior for other kinds of read errors).
1060 - If a device-file/special-file changes permissions, rsync now updates the
1061 permissions without recreating the file.
1063 - If the user specifies a remote-host for both the source and destination,
1064 we now output a syntax error rather than trying to open the destination
1065 hostspec as a filename.
1067 - When --inplace creates a new destination file, rsync now creates it with
1068 permissions 0600 instead of 0000 -- this makes restarting possible when
1069 the transfer gets interrupted in the middle of sending a new file.
1071 - Reject the combination of --inplace and --sparse since the sparse-output
1072 algorithm doesn't work when overwriting existing data.
1074 - Fixed the directory name in the error that is output when pop_dir()
1077 - Really fixed the parsing of a "!" entry in .cvsignore files this time.
1079 - If the generator gets a stat() error on a file, output it (this used to
1080 require at least -vv for the error to be seen).
1082 - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
1083 the exit status properly and generate a better error.
1085 - Fixed some glitches in the double-verbose output when using --copy-dest,
1086 --link-dest, or --compare-dest. Also improved how the verbose output
1087 handles hard-links (within the transfer) that had an up-to-date alternate
1088 "dest" file, and copied files (via --copy-dest).
1090 - Fixed the matching of the dont-compress items (e.g. *.gz) against files
1091 that have a path component containing a slash.
1093 - If the code reading a filter/exclude file gets an EINTR error, rsync now
1094 clears the error flag on the file handle so it can keep on reading.
1096 - If --relative is active, the sending side cleans up trailing "/" or "/."
1097 suffixes to avoid triggering a bug in older rsync versions. Also, we now
1098 reject a ".." dir if it would be sent as a relative dir.
1100 - If a non-directory is in the way of a directory and rsync is run with
1101 --dry-run and --delete, rsync no longer complains about not being able
1102 to opendir() the not-yet present directory.
1104 - When --list-only is used and a non-existent local destination dir was
1105 also specified as a destination, rsync no longer generates a warning
1106 about being unable to create the missing directory.
1108 - Fixed some problems with --relative --no-implied-dirs when the
1109 destination directory did not yet exist: we can now create a symlink or
1110 device when it is the first thing in the missing dir, and --fuzzy no
1111 longer complains about being unable to open the missing dir.
1113 - Fixed a bug where the --copy-links option would not affect implied
1114 directories without --copy-unsafe-links (see --relative).
1116 - Got rid of the need for --force to be used in some circumstances with
1117 --delete-after (making it consistent with --delete-before/-during).
1119 - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
1120 when a file is too large (rsync handles the write error).
1122 - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
1123 was not properly padded with trailing '=' chars. This only affects a
1124 user that need to use a password-authenticated proxy for an outgoing
1125 daemon-rsync connection.
1127 - If we're transferring an empty directory to a new name, rsync no longer
1128 forces S_IWUSR if it wasn't already set, nor does it accidentally leave
1131 - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
1132 checksum for the current file offset.
1134 - Rsync no longer allows a single directory to be copied over a non-
1135 directory destination arg.
1139 - Added the --append option that makes rsync append data onto files that
1140 are longer on the source than the destination (this includes new files).
1142 - Added the --min-size=SIZE option to exclude small files from the
1145 - Added the --compress-level option to allow you to set how aggressive
1146 rsync's compression should be (this option implies --compress).
1148 - Enhanced the parsing of the SIZE value for --min-size and --max-size to
1149 allow easy entry of multiples of 1000 (instead of just multiples of 1024)
1150 and off-by-one values too (e.g. --max-size=8mb-1).
1152 - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
1153 high-bit characters that it thinks are unreadable in the current locale.
1155 - The new option --human-readable (-h) changes the output of --progress,
1156 --stats, and the end-of-run summary to be easier to read. If repeated,
1157 the units become powers of 1024 instead of powers of 1000. (The old
1158 meaning of -h, as a shorthand for --help, still works as long as you
1159 just use it on its own, as in "rsync -h".)
1161 - If lutimes() and/or lchmod() are around, use them to allow the
1162 preservation of attributes on symlinks.
1164 - The --link-dest option now affects symlinks and devices (when possible).
1166 - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and
1167 "post-xfer exec". These allow a command to be specified on a per-module
1168 basis that will be run before and/or after a daemon-mode transfer. (See
1169 the man page for a list of the environment variables that are set with
1170 information about the transfer.)
1172 - When using the --relative option, you can now insert a dot dir in
1173 the source path to indicate where the replication of the source dirs
1174 should start. For example, if you specify a source path of
1175 rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
1176 replicate the "baz/dir" part of the source path (note: a trailing
1177 dot dir is unaffected unless it also has a trailing slash).
1179 - Added some new --no-FOO options that make it easier to override unwanted
1180 implied or default options. For example, "-a --no-o" (aka "--archive
1181 --no-owner") can be used to turn off the preservation of file ownership
1182 that is implied by -a.
1184 - Added the --chmod=MODE option that allows the destination permissions to
1185 be changed from the source permissions. E.g. --chmod=g+w,o-rwx
1187 - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
1188 a module to specify what permissions changes should be applied to all
1189 files copied to and from the daemon.
1191 - Allow the --temp-dir option to be specified when starting a daemon, which
1192 sets the default temporary directory for incoming files.
1194 - If --delete is combined with --dirs without --recursive, rsync will now
1195 delete in any directory whose content is being synchronized.
1197 - If --backup is combined with --delete without --backup-dir (and without
1198 --delete-excluded), we add a "protect" filter-rule to ensure that files
1199 with the backup suffix are not deleted.
1201 - The file-count stats that are output by --progress were improved to
1202 better indicate what the numbers mean. For instance, the output:
1203 "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
1204 to be transferred, and we still need to check 8383 more files out of
1207 - The include/exclude code now allows a dir/*** directive (with 3 trailing
1208 stars) to match both the dir itself as well as all the content below the
1209 dir (dir/** would not match the dir).
1211 - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
1212 discard empty chains of directories from the file-list. This makes it
1213 easier to selectively copy files from a source hierarchy and end up with
1214 just the directories needed to hold the resulting files.
1216 - If the --itemize-changes (-i) option is repeated, rsync now includes
1217 unchanged files in the itemized output (similar to -vv, but without all
1218 the other verbose messages that can get in the way). Of course, the
1219 client must be version 2.6.7 for this to work, but the remote rsync only
1220 needs to be 2.6.7 if you're pushing files.
1222 - Added the --specials option to tell rsync to copy non-device special
1223 files (which rsync now attempts even as a normal user). The --devices
1224 option now requests the copying of just devices (character and block).
1225 The -D option still requests both (e.g. --devices and --specials), -a
1226 still implies -D, and non-root users still get a silent downgrade that
1227 omits device copying.
1229 - Added the --super option to make the receiver always attempt super-user
1230 activities. This is useful for systems that allow things such as devices
1231 to be created or ownership to be set without being UID 0, and is also
1232 useful for someone who wants to ensure that errors will be output if the
1233 receiving rsync isn't being run as root.
1235 - Added the --sockopts option for those few who want to customize the TCP
1236 options used to contact a daemon rsync.
1238 - Added a way for the --temp-dir option to be combined with a partial-dir
1239 setting that lets rsync avoid non-atomic updates (for those times when
1240 --temp-dir is not being used because space is tight).
1242 - A new support script, files-to-excludes, will transform a list of files
1243 into a set of include/exclude directives that will copy those files.
1245 - A new option, --executability (-E) can be used to preserve just the
1246 execute bit on files, for those times when using the --perms option is
1249 - The daemon now logs each connection and also each module-list request
1252 - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
1253 (permission bits, e.g. "rwxr-xrwt").
1255 - The --dry-run option no longer forces the enabling of --verbose.
1257 - The --remove-sent-files option now does a better job of incrementally
1258 removing the sent files on the sending side (older versions tended to
1259 clump up all the removals at the end).
1261 - A daemon now supersedes its minimal SIGCHLD handler with the standard
1262 PID-remembering version after forking. This ensures that the generator
1263 can get the child-exit status from the receiver.
1265 - Use of the --bwlimit option no longer interferes with the remote rsync
1266 sending error messages about invalid/refused options.
1268 - Rsync no longer returns a usage error when used with one local source arg
1269 and no destination: this now implies the --list-only option, just like
1270 the comparable situation with a remote source arg.
1272 - Added the --copy-dirlinks option, a more limited version of --copy-links.
1274 - Various documentation improvements, including: a better synopsis, some
1275 improved examples, a better discussion of the presence and absence of
1276 --perms (including how it interacts with the new --executability and
1277 --chmod options), an extended discussion of --temp-dir, an improved
1278 discussion of --partial-dir, a better description of rsync's pattern
1279 matching characters, an improved --no-implied-dirs section, and the
1280 documenting of what the --stats option outputs.
1282 - Various new and updated diffs in the patches dir, including: acls.diff,
1283 xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
1287 - We now use sigaction() and sigprocmask() if possible, and fall back on
1288 signal() if not. Using sigprocmask() ensures that rsync enables all the
1289 signals that it needs, just in case it was started in a masked state.
1291 - Some buffer sizes were expanded a bit, particularly on systems where
1292 MAXPATHLEN is overly small (e.g. cygwin).
1294 - If io_printf() tries to format more data than fits in the buffer, exit
1295 with an error instead of transmitting a truncated buffer.
1297 - If a va_copy macro is defined, lib/snprintf.c will use it when defining
1300 - Reduced the amount of stack memory needed for each level of directory
1301 recursion by nearly MAXPATHLEN bytes.
1303 - The wildmatch function was extended to allow an array of strings to be
1304 supplied as the string to match. This allows the exclude code to do less
1307 - Got rid of the safe_fname() function (and all the myriad calls) and
1308 replaced it with a new function in the log.c code that filters all the
1309 output going to the terminal.
1311 - Unified the f_name() and the f_name_to() functions.
1313 - Improved the hash-table code the sender uses to handle checksums to make
1314 it use slightly less memory and run just a little faster.
1318 - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
1319 the previous -p0. Also, the version included in the release tar now
1320 affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
1321 it is no longer necessary to run autoconf and/or yodl unless you're
1322 applying a patch that was checked out from CVS.
1324 - Several diffs in the patches dir now use the proper --enable-FOO
1325 configure option instead of --with-FOO to turn on the inclusion of
1326 the newly patched feature.
1328 - There is a new script, "prepare-source" than can be used to update the
1329 various generated files (proto.h, configure, etc.) even before configure
1330 has created the Makefile (this is mainly useful when patching the source
1331 with a patch that doesn't affect generated files).
1333 - The testsuite now sets HOME so that it won't be affected by a file such
1337 NEWS for rsync 2.6.6 (28 Jul 2005)
1338 Protocol: 29 (unchanged)
1339 Changes since 2.6.5:
1343 - The zlib code was upgraded to version 1.2.3 in order to make it more
1344 secure. While the widely-publicized security problem in zlib 1.2.2 did
1345 not affect rsync, another security problem surfaced that affects rsync's
1350 - The setting of flist->high in clean_flist() was wrong for an empty list.
1351 This could cause flist_find() to crash in certain rare circumstances
1352 (e.g. if just the right directory setup was around when --fuzzy was
1353 combined with --link-dest).
1355 - The outputting of hard-linked files when verbosity was > 1 was not right:
1356 (1) Without -i it would output the name of each hard-linked file as
1357 though it had been changed; it now outputs a "is hard linked" message for
1358 the file. (2) With -i it would output all dots for the unchanged
1359 attributes of a hard-link; it now changes those dots to spaces, as is
1360 done for other totally unchanged items.
1362 - When backing up a changed symlink or device, get rid of any old backup
1363 item so that we don't get an "already exists" error.
1365 - A couple places that were comparing a local and a remote modification-
1366 time were not honoring the --modify-window option.
1368 - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
1369 set too often (if some non-significant mode bits differed).
1371 - Fixed a really old, minor bug that could cause rsync to warn about being
1372 unable to mkdir() a path that ends in "/." because it just created the
1373 directory (required --relative, --no-implied-dirs, a source path that
1374 ended in either a trailing slash or a trailing "/.", and a non-existing
1375 destination dir to tickle the bug in a recent version).
1379 - Made the "max verbosity" setting in the rsyncd.conf file settable on a
1380 per-module basis (which now matches the documentation).
1382 - The support/rrsync script has been upgraded to verify the args of options
1383 that take args (instead of rejecting any such options). The script was
1384 also changed to try to be more secure and to fix a problem in the parsing
1385 of a pull operation that has multiple sources.
1387 - Improved the documentation that explains the difference between a
1388 normal daemon transfer and a daemon-over remote-shell transfer.
1390 - Some of the diffs supplied in the patches dir were fixed and/or
1395 - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
1396 NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
1397 find in the /etc/group file).
1399 - Added a test to the test suite, itemized.test, that tests the output of
1400 -i (log-format w/%i) and some double-verbose messages.
1403 NEWS for rsync 2.6.5 (1 Jun 2005)
1404 Protocol: 29 (unchanged)
1405 Changes since 2.6.4:
1409 - Non-printable chars in filenames are now output using backslash-
1410 escaped characters rather than '?'s. Any non-printable character is
1411 output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
1412 is now output as "\\". Rsync also uses your locale setting, which
1413 can make it treat fewer high-bit characters as non-printable.
1415 - If rsync received an empty file-list when pulling files, it would
1416 output a "nothing to do" message and exit with a 0 (success) exit
1417 status, even if the remote rsync returned an error (it did not do
1418 this under the same conditions when pushing files). This was changed
1419 to make the pulling behavior the same as the pushing behavior: we
1420 now do the normal end-of-run outputting (depending on options) and
1421 exit with the appropriate exit status.
1425 - A crash bug was fixed when a daemon had its "path" set to "/", did
1426 not have chroot enabled, and used some anchored excludes in the
1429 - Fixed a bug in the transfer of a single file when -H is specified
1430 (rsync would either infinite loop or perhaps crash).
1432 - Fixed a case where the generator might try (and fail) to tweak the
1433 write-permissions of a read-only directory in list-only mode (this
1434 only caused an annoying warning message).
1436 - If --compare-dest or --link-dest uses a locally-copied file as the
1437 basis for an updated version, log this better when --verbose or -i
1440 - Fixed the accidental disabling of --backup during the --delete-after
1443 - Restored the ability to use the --address option in client mode (in
1444 addition to its use in daemon mode).
1446 - Make sure that some temporary progress information from the delete
1447 processing does not get left on the screen when it is followed by a
1450 - When --existing skips a directory with extra verbosity, refer to it
1451 as a "directory", not a "file".
1453 - When transferring a single file to a different-named file, any
1454 generator messages that are source-file related no longer refer to
1455 the file by the destination filename.
1457 - Fixed a bug where hard-linking a group of files might fail if the
1458 generator hasn't created a needed destination directory yet.
1460 - Fixed a bug where a hard-linked group of files that is newly-linked
1461 to a file in a --link-dest dir doesn't link the files from the rest
1464 - When deleting files with the --one-file-system (-x) option set, rsync
1465 no longer tries to remove files from inside a mount-point on the
1466 receiving side. Also, we don't complain about being unable to remove
1467 the mount-point dir.
1469 - Fixed a compatibility problem when using --cvs-ignore (-C) and
1470 sending files to an older rsync without using --delete.
1472 - Make sure that a "- !" or "+ !" include/exclude pattern does not
1473 trigger the list-clearing action that is reserved for "!".
1475 - Avoid a timeout in the generator when the sender/receiver aren't
1476 handling the generator's checksum output quickly enough.
1478 - Fixed the omission of some directories in the delete processing when
1479 --relative (-R) was combined with a source path that had a trailing
1482 - Fixed a case where rsync would erroneously delete some files and then
1483 re-transfer them when the options --relative (-R) and --recursive
1484 (-r) were both enabled (along with --delete) and a source path had a
1487 - Make sure that --max-size doesn't affect a device or a symlink.
1489 - Make sure that a system with a really small MAXPATHLEN does not cause
1490 the buffers in readfd_unbuffered() to be too small to receive normal
1491 messages. (This mainly affected Cygwin.)
1493 - If a source pathname ends with a filename of "..", treat it as if
1494 "../" had been specified (so that we don't copy files to the parent
1495 dir of the destination).
1497 - If --delete is combined with a file-listing rsync command (i.e. no
1498 transfer is happening), avoid outputting a warning that we couldn't
1501 - If --stats is specified with --delete-after, ensure that all the
1502 "deleting" messages are output before the statistics.
1504 - Improved one "if" in the deletion code that was only checking errno
1505 for ENOTEMPTY when it should have also been checking for EEXIST (for
1506 compatibility with OS variations).
1510 - Added the --only-write-batch=FILE option that may be used (instead
1511 of --write-batch=FILE) to create a batch file without doing any
1512 actual updating of the destination. This allows you to divert all
1513 the file-updating data away from a slow data link (as long as you
1514 are pushing the data to the remote server when creating the batch).
1516 - When the generator is taking a long time to fill up its output buffer
1517 (e.g. if the transferred files are few, small, or missing), it now
1518 periodically flushes the output buffer so that the sender/receiver
1519 can get started on the files sooner rather than later.
1521 - Improved the keep-alive code to handle a long silence between the
1522 sender and the receiver that can occur when the sender is receiving
1523 the checksum data for a large file.
1525 - Improved the auth-errors that are logged by the daemon to include
1526 some information on why the authorization failed: wrong user,
1527 password mismatch, etc. (The client-visible message is unchanged!)
1529 - Improved the client's handling of an "@ERROR" from a daemon so that
1530 it does not complain about an unexpectedly closed socket (since we
1531 really did expect the socket to close).
1533 - If the daemon can't open the log-file specified in rsyncd.conf, fall
1534 back to using syslog and log an appropriate warning. This is better
1535 than what was typically a totally silent (and fatal) failure (since a
1536 daemon is not usually run with the --no-detach option that was
1537 necessary to see the error on stderr).
1539 - The man pages now consistently refer to an rsync daemon as a "daemon"
1540 instead of a "server" (to distinguish it from the server process in a
1541 non-daemon transfer).
1543 - Made a small change to the rrsync script (restricted rsync -- in the
1544 support dir) to make a read-only server reject all --remove-* options
1545 when sending files (to future-proof it against the possibility of
1546 other similar options being added at some point).
1550 - Rsync now calls setlocale(LC_CTYPE, ""). This enables isprint() to
1551 better discern which filename characters need to be escaped in
1552 messages (which should result in fewer escaped characters in some
1555 - Improved the naming of the log-file open/reopen/close functions.
1557 - Removed some protocol-compatibility code that was only needed to help
1558 someone running a pre-release of 2.6.4.
1562 - Added configure option "--disable-locale" to disable any use of
1563 setlocale() in the binary.
1565 - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
1566 rsync from being built without symlink or hard-link support.
1568 - Only #define HAVE_REMSH if it is going to be set to 1.
1570 - Configure now disables the use of mkstemp() under HP-UX (since they
1571 refuse to fix its broken handling of large files).
1573 - Configure now explicitly checks for the lseek64() function so that
1574 the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
1575 presence based on the presence of the off64_t type.
1577 - Configure no longer mentions the change in the default remote-shell
1578 (from rsh to ssh) that occurred for the 2.6.0 release.
1580 - Some minor enhancements to the test scripts.
1582 - Added a few new *.diff files to the patches dir, including a patch
1583 that enables the optional copying of extended attributes.
1586 NEWS for rsync 2.6.4 (30 March 2005)
1587 Protocol: 29 (changed)
1588 Changes since 2.6.3:
1592 - When rsync deletes a directory and outputs a verbose message about
1593 it, it now appends a trailing slash to the name instead of (only
1594 sometimes) outputting a preceding "directory " string.
1596 - The --stats output will contain file-list time-statistics if both
1597 sides are 2.6.4, or if the local side is 2.6.4 and the files are
1598 being pushed (since the stats come from the sending side).
1599 (Requires protocol 29 for a pull.)
1601 - The "%o" (operation) log-format escape now has a third value (besides
1602 "send" and "recv"): "del." (with trailing dot to make it 4 chars).
1603 This changes the way deletions are logged in the daemon's log file.
1605 - When the --log-format option is combined with --verbose, rsync now
1606 avoids outputting the name of the file twice in most circumstances.
1607 As long as the --log-format item does not refer to any post-transfer
1608 items (such as %b or %c), the --log-format message is output prior to
1609 the transfer, so --verbose is now the equivalent of a --log-format of
1610 '%n%L' (which outputs the name and any link info). If the log output
1611 must occur after the transfer to be complete, the only time the name
1612 is also output prior to the transfer is when --progress was specified
1613 (so that the name will precede the progress stats, and the full
1614 --log-format output will come after).
1616 - Non-printable characters in filenames are replaced with a '?' to
1617 avoid corrupting the screen or generating empty lines in the output.
1621 - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
1622 was only treating it as a special token in an rsync include/exclude
1625 - The combination of --verbose and --dry-run now mentions the full list
1626 of changes that would be output without --dry-run.
1628 - Avoid a mkdir warning when removing a directory in the destination
1629 that already exists in the --backup-dir.
1631 - An OS that has a binary mode for its files (such as cygwin) needed
1632 setmode(fd, O_BINARY) called on the temp-file we opened with
1633 mkstemp(). (Fix derived from cygwin's 2.6.3 rsync package.)
1635 - Fixed a potential hang when verbosity is high, the client side is
1636 the sender, and the file-list is large.
1638 - Fixed a potential protocol-corrupting bug where the generator could
1639 merge a message from the receiver into the middle of a multiplexed
1640 packet of data if only part of that data had been written out to the
1641 socket when the message from the generator arrived.
1643 - We now check if the OS doesn't support using mknod() for creating
1644 FIFOs and sockets, and compile-in some compatibility code using
1645 mkfifo() and socket() when necessary.
1647 - Fixed an off-by-one error in the handling of --max-delete=N. Also,
1648 if the --max-delete limit is exceeded during a run, we now output a
1649 warning about this at the end of the run and exit with a new error
1652 - One place in the code wasn't checking if fork() failed.
1654 - The "ignore nonreadable" daemon parameter used to erroneously affect
1655 readable symlinks that pointed to a non-existent file.
1657 - If the OS does not have lchown() and a chown() of a symlink will
1658 affect the referent of a symlink (as it should), we no longer try
1659 to set the user and group of a symlink.
1661 - The generator now properly runs the hard-link loop and the dir-time
1662 rewriting loop after we're sure that the redo phase is complete.
1664 - When --backup was specified with --partial-dir=DIR, where DIR is a
1665 relative path, the backup code was erroneously trying to backup a
1666 file that was put into the partial-dir.
1668 - If a file gets resent in a single transfer and the --backup option is
1669 enabled along with --inplace, rsync no longer performs a duplicate
1670 backup (it used to overwrite the first backup with the failed file).
1672 - One call to flush_write_file() was not being checked for an error.
1674 - The --no-relative option was not being sent from the client to a
1677 - If an rsync daemon specified "dont compress = ..." for a file and the
1678 client tried to specify --compress, the libz code was not handling a
1679 compression level of 0 properly. This could cause a transfer failure
1680 if the block-size for a file was large enough (e.g. rsync might have
1681 exited with an error for large files).
1683 - Fixed a bug that would sometimes surface when using --compress and
1684 sending a file with a block-size larger than 64K (either manually
1685 specified, or computed due to the file being really large). Prior
1686 versions of rsync would sometimes fail to decompress the data
1687 properly, and thus the transferred file would fail its verification.
1689 - If a daemon can't open the specified log file (i.e. syslog is not
1690 being used), die without crashing. We also output an error about
1691 the failure on stderr (which will only be seen if --no-detach was
1692 specified) and exit with a new error code (6).
1694 - A local transfer no longer duplicates all its include/exclude options
1695 (since the forked process already has a copy of the exclude list,
1696 there's no need to send them a set of duplicates).
1698 - The output of the items that are being updated by the generator (dirs,
1699 symlinks, devices) is now intermingled in the proper order with the
1700 output from the items that the receiver is updating (regular files)
1701 when pulling. This misordering was particularly bad when --progress
1702 was specified. (Requires protocol 29.)
1704 - When --timeout is specified, lulls that occur in the transfer while
1705 the generator is doing work that does not generate socket traffic
1706 (looking for changed files, deleting files, doing directory-time
1707 touch-ups, etc.) will cause a new keep-alive packet to be sent that
1708 should keep the transfer going as long as the generator continues to
1709 make progress. (Requires protocol 29.)
1711 - The stat size of a device is not added to the total file size of the
1712 items in the transfer (the size might be undefined on some OSes).
1714 - Fixed a problem with refused-option messages sometimes not making it
1715 back to the client side when a remote --files-from was in effect and
1716 the daemon was the receiver.
1718 - The --compare-dest option was not updating a file that differed in
1719 (the preserved) attributes from the version in the compare-dest DIR.
1721 - When rsync is copying files into a write-protected directory, fixed
1722 the change-report output for the directory so that we don't report
1723 an identical directory as changed.
1727 - Rsync now supports popt's option aliases, which means that you can
1728 use /etc/popt and/or ~/.popt to create your own option aliases.
1730 - Added the --delete-during (--del) option which will delete files
1731 from the receiving side incrementally as each directory in the
1732 transfer is being processed. This makes it more efficient than the
1733 default, before-the-transfer behavior, which is now also available as
1734 --delete-before (and is still the default --delete-WHEN option that
1735 will be chosen if --delete or --delete-excluded is specified without
1736 a --delete-WHEN choice). All the --del* options infer --delete, so
1737 an rsync daemon that refuses "delete" will still refuse to allow any
1738 file-deleting options (including the new --remove-sent-files option).
1740 - All the --delete-WHEN options are now more memory efficient:
1741 Previously an duplicate set of file-list objects was created on the
1742 receiving side for the entire destination hierarchy. The new
1743 algorithm only creates one directory of objects at a time (for files
1744 inside the transfer).
1746 - Added the --copy-dest option, which works like --link-dest except
1747 that it locally copies identical files instead of hard-linking them.
1749 - Added support for specifying multiple --compare-dest, --copy-dest, or
1750 --link-dest options, but only of a single type. (Promoted from the
1751 patches dir and enhanced.) (Requires protocol 29.)
1753 - Added the --max-size option. (Promoted from the patches dir.)
1755 - The daemon-mode options are now separated from the normal rsync
1756 options so that they can't be mixed together. This makes it
1757 impossible to start a daemon that has improper default option values
1758 (which could cause problems when a client connects, such as hanging
1761 - The --bwlimit option may now be used in combination with --daemon
1762 to specify both a default value for the daemon side and a value
1763 that cannot be exceeded by a user-specified --bwlimit option.
1765 - Added the "port" parameter to the rsyncd.conf file. (Promoted from
1766 the patches dir.) Also added "address". The command-line options
1767 take precedence over a config-file option, as expected.
1769 - In _exit_cleanup(): when we are exiting with a partially-received
1770 file, we now flush any data in the write-cache before closing the
1773 - The --inplace support was enhanced to work with --compare-dest,
1774 --link-dest, and (the new) --copy-dest options. (Requires protocol
1777 - Added the --dirs (-d) option for an easier way to copy directories
1778 without recursion. Any directories that are encountered are created
1779 on the destination. Specifying a directory with a trailing slash
1780 copies its immediate contents to the destination.
1782 - The --files-from option now implies --dirs (-d).
1784 - Added the --list-only option, which is mainly a way for the client to
1785 put the server into listing mode without needing to resort to any
1786 internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
1787 for a non-recursive listing). This option is used automatically
1788 (behind the scenes) when a modern rsync speaks to a modern daemon,
1789 but may also be specified manually if you want to force the use of
1790 the --list-only option over a remote-shell connection.
1792 - Added the --omit-dir-times (-O) option, which will avoid updating
1793 the modified time for directories when --times was specified. This
1794 option will avoid an extra pass through the file-list at the end of
1795 the transfer (to tweak all the directory times), which may provide
1796 an appreciable speedup for a really large transfer. (Promoted from
1799 - Added the --filter (-f) option and its helper option, -F. Filter
1800 rules are an extension to the existing include/exclude handling
1801 that also supports nested filter files as well as per-directory
1802 filter files (like .cvsignore, but with full filter-rule parsing).
1803 This new option was chosen in order to ensure that all existing
1804 include/exclude processing remained 100% compatible with older
1805 versions. Protocol 29 is needed for full filter-rule support, but
1806 backward-compatible rules work with earlier protocol versions.
1807 (Promoted from the patches dir and enhanced.)
1809 - Added the --delay-updates option that puts all updated files into
1810 a temporary directory (by default ".~tmp~", but settable via the
1811 --partial-dir=DIR option) until the end of the transfer. This
1812 makes the updates a little more atomic for a large transfer.
1814 - If rsync is put into the background, any output from --progress is
1817 - Documented the "max verbosity" setting for rsyncd.conf. (This
1818 setting was added a couple releases ago, but left undocumented.)
1820 - The sender and the generator now double-check the file-list index
1821 they are given, and refuse to try to do a file transfer on a
1822 non-file index (since that would indicate that something had gone
1825 - Added the --itemize-changes (-i) option, which is a way to output a
1826 more detailed list of what files changed and in what way. The effect
1827 is the same as specifying a --log-format of "%i %n%L" (see both the
1828 rsync and rsyncd.conf manpages). Works with --dry-run too.
1830 - Added the --fuzzy (-y) option, which attempts to find a basis file
1831 for a file that is being created from scratch. The current algorithm
1832 only looks in the destination directory for the created file, but it
1833 does attempt to find a match based on size/mod-time (in case the file
1834 was renamed with no other changes) as well as based on a fuzzy
1835 name-matching algorithm. This option requires protocol 29 because it
1836 needs the new file-sorting order. (Promoted from patches dir and
1837 enhanced.) (Requires protocol 29.)
1839 - Added the --remove-sent-files option, which lets you move files
1842 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
1843 enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
1844 literals in the rsync://HOST:PORT/PATH format.)
1846 - When rsync recurses to build the file list, it no longer keeps open
1847 one or more directory handles from the dir's parent dirs.
1849 - When building under windows, the default for --daemon is now to
1850 avoid detaching, requiring the new --detach option to force rsync
1853 - The --dry-run option can now be combined with either --write-batch or
1854 --read-batch, allowing you to run a do-nothing test command to see
1855 what would happen without --dry-run.
1857 - The daemon's "read only" config item now sets an internal read_only
1858 variable that makes extra sure that no write/delete calls on the
1859 read-only side can succeed.
1861 - The log-format % escapes can now have a numeric field width in
1862 between the % and the escape letter (e.g. "%-40n %08p").
1864 - Improved the option descriptions in the --help text.
1868 - Added atomic-rsync to the support dir: a perl script that will
1869 transfer some files using rsync, and then move the updated files into
1870 place all at once at the end of the transfer. Only works when
1871 pulling, and uses --link-dest and a parallel hierarchy of files to
1874 - Added mnt-excl to the support dir: a perl script that takes the
1875 /proc/mounts file and translates it into a set of excludes that will
1876 exclude all mount points (even mapped mounts to the same disk). The
1877 excludes are made relative to the specified source dir and properly
1880 - Added savetransfer.c to the support dir: a C program that can make
1881 a copy of all the data that flows over the wire. This lets you test
1882 for data corruption (by saving the data on both the sending side and
1883 the receiving side) and provides one way to debug a protocol error.
1885 - Added rrsync to the support dir: this is an updated version of Joe
1886 Smith's restricted rsync perl script. This helps to ensure that only
1887 certain rsync commands can be run by an ssh invocation.
1891 - Added better checking of the checksum-header values that come over
1894 - Merged a variety of file-deleting functions into a single function so
1895 that it is easier to maintain.
1897 - Improved the type of some variables (particularly blocksize vars) for
1898 consistency and proper size.
1900 - Got rid of the uint64 type (which we didn't need).
1902 - Use a slightly more compatible set of core #include directives.
1904 - Defined int32 in a way that ensures that the build dies if we can't
1905 find a variable with at least 32 bits.
1907 PROTOCOL DIFFERENCES FOR VERSION 29:
1909 - A 16-bit flag-word is transmitted after every file-list index. This
1910 indicates what is changing between the sender and the receiver. The
1911 generator now transmits an index and a flag-word to indicate when
1912 dirs and symlinks have changed (instead of producing a message),
1913 which makes the outputting of the information more consistent and
1914 less prone to screen corruption (because the local receiver/sender is
1915 now outputting all the file-change info messages).
1917 - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
1918 in the flag-word and the name of the file that was linked immediately
1919 follows in vstring format (see below).
1921 - If a file is being transferred with an alternate-basis file, the
1922 ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
1923 byte follows, indicating what type of basis file was chosen. If that
1924 indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
1925 is set in the flag-word and the name of the match in vstring format
1926 follows the basis byte. A vstring is a variable length string that
1927 has its size written prior to the string, and no terminating null.
1928 If the string is from 1-127 bytes, the length is a single byte. If
1929 it is from 128-32767 bytes, the length is written as ((len >> 8) |
1930 0x80) followed by (len % 0x100).
1932 - The sending of exclude names is done using filter-rule syntax. This
1933 means that all names have a prefixed rule indicator, even excludes
1934 (which used to be sent as a bare pattern, when possible). The -C
1935 option will include the per-dir .cvsignore merge file in the list of
1936 filter rules so it is positioned correctly (unlike in some older
1937 transfer scenarios).
1939 - Rsync sorts the filename list in a different way: it sorts the subdir
1940 names after the non-subdir names for each dir's contents, and it
1941 always puts a dir's contents immediately after the dir's name in the
1942 list. (Previously an item named "foo.txt" would sort in between
1943 directory "foo/" and "foo/bar".)
1945 - When talking to a protocol 29 rsync daemon, a list-only request
1946 is able to note this before the options are sent over the wire and
1947 the new --list-only option is included in the options.
1949 - When the --stats bytes are sent over the wire (or stored in a batch),
1950 they now include two elapsed-time values: one for how long it took to
1951 build the file-list, and one for how long it took to send it over the
1952 wire (each expressed in thousandths of a second).
1954 - When --delete-excluded is specified with some filter rules (AKA
1955 excludes), a client sender will now initiate a send of the rules to
1956 the receiver (older protocols used to omit the sending of excludes in
1957 this situation since there were no receiver-specific rules that
1958 survived --delete-excluded back then). Note that, as with all the
1959 filter-list sending, only items that are significant to the other
1960 side will actually be sent over the wire, so the filter-rule list
1961 that is sent in this scenario is often empty.
1963 - An index equal to the file-list count is sent as a keep-alive packet
1964 from the generator to the sender, which then forwards it on to the
1965 receiver. This normally invalid index is only a valid keep-alive
1966 packet if the 16-bit flag-word that follows it contains a single bit
1967 (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
1969 - A protocol-29 batch file includes a bit for the setting of the --dirs
1970 option and for the setting of the --compress option. Also, the shell
1971 script created by --write-batch will use the --filter option instead
1972 of --exclude-from to capture any filter rules.
1976 - Handle an operating system that use mkdev() in place of makedev().
1978 - Improved configure to better handle cross-compiling.
1981 NEWS for rsync 2.6.3 (30 Sep 2004)
1982 Protocol: 28 (unchanged)
1983 Changes since 2.6.2:
1987 - A bug in the sanitize_path routine (which affects a non-chrooted
1988 rsync daemon) could allow a user to craft a pathname that would get
1989 transformed into an absolute path for certain options (but not for
1990 file-transfer names). If you're running an rsync daemon with chroot
1991 disabled, *please upgrade*, ESPECIALLY if the user privs you run
1992 rsync under is anything above "nobody".
1994 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
1996 - Please note that the 2-line footer (output when verbose) now uses the
1997 term "sent" instead of "wrote" and "received" instead of "read". If
1998 you are not parsing the numeric values out of this footer, a script
1999 would be better off using the empty line prior to the footer as the
2000 indicator that the verbose output is over.
2002 - The output from the --stats option was similarly affected to change
2003 "written" to "sent" and "read" to "received".
2005 - Rsync ensures that a filename that contains a newline gets mentioned
2006 with each newline transformed into a question mark (which prevents a
2007 filename from causing an empty line to be output).
2009 - The "backed up ..." message that is output when at least 2 --verbose
2010 options are specified is now the same both with and without the
2011 --backup-dir option.
2015 - Fixed a crash bug that might appear when --delete was used and
2016 multiple source directories were specified.
2018 - Fixed a 32-bit truncation of the file length when generating the
2021 - The --backup code no longer attempts to create some directories
2022 over and over again (generating warnings along the way).
2024 - Fixed a bug in the reading of the secrets file (by the daemon) and
2025 the password file (by the client): the files no longer need to be
2026 terminated by a newline for their content to be read in.
2028 - If a file has a read error on the sending side or the reconstructed
2029 data doesn't match the expected checksum (perhaps due to the basis
2030 file changing during the transfer), the receiver will no longer
2031 retain the resulting file unless the --partial option was specified.
2032 (Note: for the read-error detection to work, neither side can be
2033 older than 2.6.3 -- older receivers will always retain the file, and
2034 older senders don't tell the receiver that the file had a read
2037 - If a file gets resent in a single transfer and the --backup option
2038 is enabled, rsync no longer performs a duplicate backup (it used to
2039 overwrite the original file in the backup area).
2041 - Files specified in the daemon's "exclude" or "exclude from" config
2042 items are now excluded from being uploaded (assuming that the module
2043 allows uploading at all) in addition to the old download exclusion.
2045 - Got rid of a potential hang in the receiver when near the end of a
2048 - When using --backup without a --backup-dir, rsync no longer preserves
2049 the modify time on directories. This avoids confusing NFS.
2051 - When --copy-links (-L) is specified, we now output a separate error
2052 for a symlink that has no referent instead of claiming that a file
2055 - The --copy-links (-L) option no longer has the side-effect of telling
2056 the receiving side to follow symlinks. See the --keep-dirlinks
2057 option (mentioned below) for a way to specify that behavior.
2059 - Error messages from the daemon server's option-parsing (such as
2060 refused options) are now successfully transferred back to the client
2061 (the server used to fail to send the message because the socket
2062 wasn't in the right state for the message to get through).
2064 - Most transfer errors that occur during a daemon transfer are now
2065 returned to the user in addition to being logged (some messages are
2066 intended to be daemon-only and are not affected by this).
2068 - Fixed a bug in the daemon authentication code when using one of the
2069 batch-processing options.
2071 - We try to work around some buggy IPv6 implementations that fail to
2072 implement IPV6_V6ONLY. This should fix the "address in use" error
2073 that some daemons get when running on an OS with a buggy IPv6
2074 implementation. Also, if the new code gets this error, we might
2075 suggest that the user specify --ipv4 or --ipv6 (if we think it will
2078 - When the remote rsync dies, make a better effort to recover any error
2079 messages it may have sent before dying (the local rsync used to just
2080 die with a socket-write error).
2082 - When using --delete and a --backup-dir that contains files that are
2083 hard-linked to their destination equivalents, rsync now makes sure
2084 that removed files really get removed (avoids a really weird rename()
2087 - Avoid a bogus run-time complaint about a lack of 64-bit integers when
2088 the int64 type is defined as an off_t and it actually has 64-bits.
2090 - Added a configure check for open64() without mkstemp64() so that we
2091 can avoid using mkstemp() when such a combination is encountered.
2092 This bypasses a problem writing out large temp files on OSes such as
2095 - Fixed an age-old crash problem with --read-batch on a local copy
2096 (rsync was improperly assuming --whole-file for the local copy).
2098 - When --dry-run (-n) is used and the destination directory does not
2099 exist, rsync now produces a correct report of files that would be
2100 sent instead of dying with a chdir() error.
2102 - Fixed a bug that could cause a slow-to-connect rsync daemon to die
2103 with an error instead of waiting for the connection to finish.
2105 - Fixed an ssh interaction that could cause output to be lost when the
2106 user chose to combine the output of rsync's stdout and stderr (e.g.
2109 - Fixed an option-parsing bug when --files-from got passed to a daemon.
2113 - Added the --partial-dir=DIR option that lets you specify where to
2114 (temporarily) put a partially transferred file (instead of over-
2115 writing the destination file). E.g. --partial-dir=.rsync-partial
2116 Also added support for the RSYNC_PARTIAL_DIR environment variable
2117 that, when found, transforms a regular --partial option (such as
2118 the convenient -P option) into one that also specifies a directory.
2120 - Added --keep-dirlinks (-K), which allows you to symlink a directory
2121 onto another partition on the receiving side and have rsync treat it
2122 as matching a normal directory from the sender.
2124 - Added the --inplace option that tells rsync to write each destination
2125 file without using a temporary file. The matching of existing data
2126 in the destination file can be severely limited by this, but there
2127 are also cases where this is more efficient (such as appending data).
2128 Use only when needed (see the man page for more details).
2130 - Added the "write only" option for the daemon's config file.
2132 - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
2133 and documented all these options in the man page.
2135 - Improved the handling of the --bwlimit option so that it's less
2136 bursty, more accurate, and works properly over a larger range of
2139 - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
2140 SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
2142 - Added the --checksum-seed=N option for advanced users.
2144 - Batch writing/reading has a brand-new implementation that is simpler,
2145 fixes a few weird problems with the old code (such as no longer
2146 sprinkling the batch files into different dirs or even onto different
2147 systems), and is much less intrusive into the code (making it easier
2148 to maintain for the future). The new code generates just one data
2149 file instead of three, which makes it possible to read the batch on
2150 stdin via a remote shell. Also, the old requirement of forcing the
2151 same fixed checksum-seed for all batch processing has been removed.
2153 - If an rsync daemon has a module set with "list = no" (which hides its
2154 presence in the list of available modules), a user that fails to
2155 authenticate gets the same "unknown module" error that they would get
2156 if the module were actually unknown (while still logging the real
2157 error to the daemon's log file). This prevents fishing for module
2160 - The daemon's "refuse options" config item now allows you to match
2161 option names using wildcards and/or the single-letter option names.
2163 - Each transferred file now gets its permissions and modified-time
2164 updated before the temp-file gets moved into place. Previously, the
2165 finished file would have a very brief window where its permissions
2166 disallowed all group and world access.
2168 - Added the ability to parse a literal IPv6 address in an "rsync:" URL
2169 (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
2171 - The daemon's wildcard expanding code can now handle more than 1000
2172 filenames (it's now limited by memory instead of having a hard-wired
2177 - Some cleanup in the exclude code has saved some per-exclude memory
2178 and made the code easier to maintain.
2180 - Improved the argv-overflow checking for a remote command that has a
2183 - Use rsyserr() in the various places that were still calling rprintf()
2184 with strerror() as an arg.
2186 - If an rsync daemon is listening on multiple sockets (to handle both
2187 IPv4 and IPv6 to a single port), we now close all the unneeded file
2188 handles after we accept a connection (we used to close just one of
2191 - Optimized the handling of larger block sizes (rsync used to slow to a
2192 crawl if the block size got too large).
2194 - Optimized away a loop in hash_search().
2196 - Some improvements to the sanitize_path() and clean_fname() functions
2197 makes them more efficient and produce better results (while still
2198 being compatible with the file-name cleaning that gets done on both
2199 sides when sending the file-list).
2201 - Got rid of alloc_sanitize_path() after adding a destination-buffer
2202 arg to sanitize_path() made it possible to put all the former's
2203 functionality into the latter.
2205 - The file-list that is output when at least 4 verbose options are
2206 specified reports the uid value on the sender even when rsync is
2207 not running as root (since we might be sending to a root receiver).
2211 - Added a "gen" target to rebuild most of the generated files,
2212 including configure, config.h.in, the man pages, and proto.h.
2214 - If "make proto" doesn't find some changes in the prototypes, the
2215 proto.h file is left untouched (its time-stamp used to always be
2218 - The variable $STRIP (that is optionally set by the install-strip
2219 target's rule) was changed to $INSTALL_STRIP because some systems
2220 have $STRIP already set in the environment.
2222 - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
2224 - When cross-compiling, the gettimeofday() function is now assumed to
2225 be a modern version that takes two-args (since we can't test it).
2229 - The scripts in the testsuite dir were cleaned up a bit and a few
2232 - Some new diffs were added to the patches dir, and some accepted
2236 NEWS for rsync 2.6.2 (30 Apr 2004)
2237 Protocol: 28 (unchanged)
2238 Changes since 2.6.1:
2242 - Fixed a major bug in the sorting of the filenames when --relative
2243 is used for some sources (just sources such as "/" and "/*" were
2244 affected). This fix ensures that we ask for the right file-list
2245 item when requesting changes from the sender.
2247 - Rsync now checks the return value of the close() function to
2248 better report disk-full problems on an NFS file system.
2250 - Restored the old daemon-server behavior of logging error messages
2251 rather than returning them to the user. (A better long-term fix
2252 will be sought in the future.)
2254 - An obscure uninitialized-variable bug was fixed in the uid/gid
2255 code. (This bug probably had no ill effects.)
2259 - Got rid of the configure check for sys/sysctl.h (it wasn't used
2260 and was causing a problem on some systems). Also improved the
2261 broken-largefile-locking test to try to avoid failure due to an
2264 - Fixed a compile problem on systems that don't define
2267 - Fixed a compile problem in the popt source for compilers that
2268 don't support __attribute__.
2272 - Improved the testsuite's "merge" test to work on OSF1.
2274 - Two new diffs were added to the patches dir.
2277 NEWS for rsync 2.6.1 (26 Apr 2004)
2278 Protocol: 28 (changed)
2279 Changes since 2.6.0:
2283 - Paths sent to an rsync daemon are more thoroughly sanitized when
2284 chroot is not used. If you're running a non-read-only rsync
2285 daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
2286 user privs you run rsync under is anything above "nobody".
2290 - Lower memory use, more optimal transfer of data over the socket,
2291 and lower CPU usage (see the INTERNAL section for details).
2293 - The RSYNC_PROXY environment variable can now contain a
2294 "USER:PASS@" prefix before the "HOST:PORT" information.
2297 - The --progress output now mentions how far along in the transfer
2298 we are, including both a count of files transferred and a
2299 percentage of the total file-count that we've processed. It also
2300 shows better current-rate-of-transfer and remaining-transfer-time
2303 - Documentation changes now attempt to describe some often mis-
2304 understood features more clearly.
2308 - When -x (--one-file-system) is combined with -L (--copy-links) or
2309 --copy-unsafe-links, no symlinked files are skipped, even if the
2310 referent file is on a different filesystem.
2312 - The --link-dest code now works properly for a non-root user when
2313 (1) the UIDs of the source and destination differ and -o was
2314 specified, or (2) when the group of the source can't be used on
2315 the destination and -g was specified.
2317 - Fixed a bug in the handling of -H (hard-links) that might cause
2318 the expanded PATH/NAME value of the current item to get
2319 overwritten (due to an expanded-name caching bug).
2321 - We now reset the "new data has been sent" flag at the start of
2322 each file we send. This makes sure that an interrupted transfer
2323 with the --partial option set doesn't keep a shorter temp file
2324 than the current basis file when no new data has been transferred
2325 over the wire for that file.
2327 - Fixed a byte-order problem in --batch-mode on big-endian machines.
2330 - When using --cvs-exclude, the exclude items we get from a
2331 per-directory's .cvsignore file once again only affect that one
2332 directory (not all following directories too). The items are also
2333 now properly word-split and parsed without any +/- prefix parsing.
2335 - When specifying the USER@HOST: prefix for a file, the USER part
2336 can now contain an '@', if needed (i.e. the last '@' is used to
2337 find the HOST, not the first).
2339 - Fixed some bugs in the handling of group IDs for non-root users:
2340 (1) It properly handles a group that the sender didn't have a name
2341 for (it would previously skip changing the group on any files in
2342 that group). (2) If --numeric-ids is used, rsync no longer
2343 attempts to set groups that the user doesn't have the permission
2346 - Fixed the "refuse options" setting in the rsyncd.conf file.
2348 - Improved the -x (--one-file-system) flag's handling of any mount-
2349 point directories we encounter. It is both more optimal (in that
2350 it no longer does a useless scan of the contents of the mount-
2351 point dirs) and also fixes a bug where a remapped mount of the
2352 original filesystem could get discovered in a subdir we should be
2355 - Rsync no longer discards a double-slash at the start of a filename
2356 when trying to open the file. It also no longer constructs names
2357 that start with a double slash (unless the user supplied them).
2359 - Path-specifying options to a daemon should now work the same with
2360 or without chroot turned on. Previously, such a option (such as
2361 --link-dest) would get its absolute path munged into a relative
2362 one if chroot was not on, making that setting fairly useless.
2363 Rsync now transforms the path into one that is based on the
2364 module's base dir when chroot is not enabled.
2366 - Fixed a compatibility problem interacting with older rsync
2367 versions that might send us an empty --suffix value without
2368 telling us that --backup-dir was specified.
2370 - The "hosts allow" option for a daemon-over-remote-shell process
2371 now has improved support for IPv6 addresses and a fix for systems
2372 that have a length field in their socket structs.
2374 - Fixed the ability to request an empty backup --suffix when sending
2375 files to an rsync daemon.
2377 - Fixed an option-parsing bug when --files-from was sent to a server
2382 - Most of the I/O is now buffered, which results in a pretty large
2383 speedup when running under MS Windows. (Craig Barratt)
2385 - Optimizations to the name-handling/comparing code have made some
2386 significant reductions in user-CPU time for large file sets.
2388 - Some cleanup of the variable types make the code more consistent.
2390 - Reduced memory requirements of hard link preservation.
2393 - Implemented a new algorithm for hard-link handling that speeds up
2394 the code significantly. (J.W. Schultz and Wayne Davison)
2396 - The --hard-link option now uses the first existing file in the
2397 group of linked files as the basis for the transfer. This
2398 prevents the sub-optimal transfer of a file's data when a new
2399 hardlink is added on the sending side and it sorts alphabetically
2400 earlier in the list than the files that are already present on the
2403 - Dropped support for protocol versions less than 20 (2.3.0 released
2404 15 Mar 1999) and activated warnings for protocols less than 25
2405 (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
2408 - More optimal data transmission for --hard-links (protocol 28).
2410 - More optimal data transmission for --checksum (protocol 28).
2412 - Less memory is used when --checksum is specified.
2414 - Less memory is used in the file list (a per-file savings).
2416 - The generator is now better about not modifying the file list
2417 during the transfer in order to avoid a copy-on-write memory
2418 bifurcation (on systems where fork() uses shared memory).
2419 Previously, rsync's shared memory would slowly become unshared,
2420 resulting in real memory usage nearly doubling on the receiving
2421 side by the end of the transfer. Now, as long as permissions
2422 are being preserved, the shared memory should remain that way
2423 for the entire transfer.
2425 - Changed hardlink info and file_struct + strings to use allocation
2426 pools. This reduces memory use for large file-sets and permits
2427 freeing memory to the OS. (J.W. Schultz)
2429 - The 2 pipes used between the receiver and generator processes
2430 (which are forked on the same machine) were reduced to 1 pipe and
2431 the protocol improved so that (1) it is now impossible to have the
2432 "redo" pipe fill up and hang rsync, and (2) trailing messages from
2433 the receiver don't get lost on their way through the generator
2434 over to the sender (which mainly affected hard-link messages and
2435 verbose --stats output).
2437 - Improved the internal uid/gid code to be more portable and a
2438 little more optimized.
2440 - The device numbers sent when using --devices are now sent as
2441 separate major/minor values with 32-bit accuracy (protocol 28).
2442 Previously, the copied devices were sent as a single 32-bit
2443 number. This will make inter-operation of 64-bit binaries more
2444 compatible with their 32-bit brethren (with both ends of the
2445 connection are using protocol 28). Note that optimizations in the
2446 binary protocol for sending the device numbers often results in
2447 fewer bytes being used than before, even though more precision is
2450 - Some cleanup of the exclude/include structures and its code made
2451 things clearer (internally), simpler, and more efficient.
2453 - The reading & writing of the file-list in batch-mode is now
2454 handled by the same code that sends & receives the list over the
2455 wire. This makes it much easier to maintain. (Note that the
2456 batch code is still considered to be experimental.)
2460 - The configure script now accepts --with-rsyncd-conf=PATH to
2461 override the default value of the /etc/rsyncd.conf file.
2463 - Fixed configure bug when running "./configure --disable-ipv6".
2465 - Fixed compilation problem on Tru64 Unix (having to do with
2466 sockaddr.sa_len and sockaddr.sin_len).
2470 - Fixed "make test" bug when build dir is not the source dir.
2472 - Added a couple extra diffs in the "patches" dir, removed the ones
2473 that got applied, and rebuilt the rest.
2476 NEWS for rsync 2.6.0 (1 Jan 2004)
2477 Protocol: 27 (changed)
2478 Changes since 2.5.7:
2482 * "ssh" is now the default remote shell for rsync. If you want to
2483 change this, configure like this: "./configure --with-rsh=rsh".
2485 * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
2486 Note that --from0 affects the line-ending character for all the
2487 files read by the --*-from options. (Wayne Davison)
2489 * Length of csum2 is now per-file starting with protocol version
2492 * Per-file dynamic block size is now sqrt(file length). The
2493 per-file checksum size is determined according to an algorithm
2494 provided by Donovan Baarda which reduces the probability of rsync
2495 algorithm corrupting data and falling back using the whole md4
2496 checksums. (J.W. Schultz, Donovan Baarda)
2498 * The --stats option no longer includes the (debug) malloc summary
2499 unless the verbose option was specified at least twice.
2501 * Added a new error/warning code for when files vanish from the
2502 sending side. Made vanished source files not interfere with the
2503 file-deletion pass when --delete-after was specified.
2505 * Various trailing-info sections are now preceded by a newline.
2509 * Fixed several exclude/include matching bugs when using wild-cards.
2510 This has a several user-visible effects, all of which make the
2511 matching more consistent and intuitive. This should hopefully not
2512 cause anyone problems since it makes the matching work more like
2513 what people are expecting. (Wayne Davison)
2515 - A pattern with a "**" no longer causes a "*" to match slashes.
2516 For example, with "/*/foo/**", "foo" must be 2 levels deep.
2517 [If your string has BOTH "*" and "**" wildcards, changing the
2518 "*" wildcards to "**" will provide the old behavior in all
2521 - "**/foo" now matches at the base of the transfer (like /foo
2522 does). [Use "/**/foo" to get the old behavior in all versions.]
2524 - A non-anchored wildcard term floats to match beyond the base of
2525 the transfer. E.g. "CVS/R*" matches at the end of the path,
2526 just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
2527 to get the old behavior in all versions.]
2529 - Including a "**" in the match term causes it to be matched
2530 against the entire path, not just the name portion, even if
2531 there aren't any interior slashes in the term. E.g. "foo**bar"
2532 would exclude "/path/foo-bar" (just like before) as well as
2533 "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
2534 old behavior in all versions.]
2536 * The exclude list specified in the daemon's config file is now
2537 properly applied to the pulled items no matter how deep the
2538 user's file-args are in the source tree. (Wayne Davison)
2540 * For protocol version >= 27, mdfour_tail() is called when the
2541 block size (including checksum_seed) is a multiple of 64.
2542 Previously it was not called, giving the wrong MD4 checksum.
2545 * For protocol version >= 27, a 64 bit bit counter is used in
2546 mdfour.c as required by the RFC. Previously only a 32 bit bit
2547 counter was used, causing incorrect MD4 file checksums for
2548 file sizes >= 512MB - 4. (Craig Barratt)
2550 * Fixed a crash bug when interacting with older rsync versions and
2551 multiple files of the same name are destined for the same dir.
2554 * Keep tmp names from overflowing MAXPATHLEN.
2556 * Make --link-dest honor the absence of -p, -o, and -g.
2558 * Made rsync treat a trailing slash in the destination in a more
2561 * Fixed file I/O error detection. (John Van Essen)
2563 * Fixed bogus "malformed address {hostname}" message in rsyncd log
2564 when checking IP address against hostnames from "hosts allow"
2565 and "hosts deny" parameters in config file.
2567 * Print heap statistics when verbose >= 2 instead of when >= 1.
2569 * Fixed a compression (-z) bug when syncing a mostly-matching file
2570 that contains already-compressed data. (Yasuoka Masahiko and
2573 * Fixed a bug in the --backup code that could cause deleted files
2574 to not get backed up.
2576 * When the backup code makes new directories, create them with mode
2577 0700 instead of 0755 (since the directory permissions in the
2578 backup tree are not yet copied from the main tree).
2580 * Call setgroups() in a more portable manner.
2582 * Improved file-related error messages to better indicate exactly
2583 what pathname failed. (Wayne Davison)
2585 * Fixed some bugs in the handling of --delete and --exclude when
2586 using the --relative (-R) option. (Wayne Davison)
2588 * Fixed bug that prevented regular files from replacing
2589 special files and caused a directory in --link-dest or
2590 --compare-dest to block the creation of a file with the
2591 same path. A directory still cannot be replaced by a
2592 regular file unless --delete specified. (J.W. Schultz)
2594 * Detect and report when open or opendir succeed but read and
2595 readdir fail caused by network filesystem issues and truncated
2596 files. (David Norwood, Michael Brown, J.W. Schultz)
2598 * Added a fix that should give ssh time to restore the tty settings
2599 if the user presses Ctrl-C at an ssh password prompt.
2603 * Eliminated vestigial support for old versions that we stopped
2604 supporting. (J.W. Schultz)
2606 * Simplified some of the option-parsing code. (Wayne Davison)
2608 * Some cleanup made to the exclude code, as well as some new
2609 defines added to enhance readability. (Wayne Davison)
2611 * Changed the protocol-version code so that it can interact at a
2612 lower protocol level than the maximum supported by both sides.
2613 Added an undocumented option, --protocol=N, to force the value
2614 we advertise to the other side (primarily for testing purposes).

2671 * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
2672 L. Allen, Martin Pool)
2674 * Generate each file's rolling-checksum data as we send it, not
2675 in a separate (memory-eating) pass before hand. This prevents

2690 processes and sometimes return an exit code of 0 instead of showing

2736 a fatal signal rsync will try to open an xterm running gdb,
2737 similarly to Samba's "panic action" or GNOME's bug-buddy.

2801 "unsigned int64" in rsync.h.
2803 * Fixed problem on systems such as Sunos4 that do not support realloc
2804 on a NULL pointer; error was "out of memory in flist_expand".

2927 sets. By Bert J. Dempsey and Debra Weiss, updated by Jos
2928 Backus. <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
2930 * IPv6 support based on a patch from KAME.net, on systems
2931 including modern versions of Linux, Solaris, and HP-UX. Also
2932 includes IPv6 compatibility functions for old OSs by the
2933 Internet Software Consortium, Paul Vixie, the OpenSSH
2934 portability project, and OpenBSD.

2939 included or excluded and why.
2941 * Many error messages have more friendly explanations and more
2944 * Manual page improvements plus scanty protocol documentation.
2946 * When running as --daemon in the background and using a "log
2947 file" rsyncd.conf directive, close the log file every time it is
2948 open when going to sleep on the socket. This allows the log
2949 file to get cleaned out by another process.
2951 * Change to using libpopt rather than getopt for processing
2952 options. This makes the code cleaner and the behaviour more
2953 consistent across platforms. popt is included and built if not
2954 installed on the platform.
2956 * More details in --version, including note about whether 64-bit
2957 files, symlinks and hardlinks are supported.
2959 * MD4 code may use less CPU cycles.
2961 * Use mkstemp on systems where it is secure. If we use mktemp,
2962 explain that we do it in a secure way.
2964 * --whole-file is the default when source and target are on the
2969 * Fix for various bugs causing rsync to hang.

2976 to transfer fail to transfer.
2978 * For log messages containing ridiculously long strings that might
2979 overflow a buffer rsync no longer aborts, but rather prints an
2980 ellipsis at the end of the string. (Patch from Ed Santiago.)
2984 * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
2986 * autoconf2.52 (or later) is now required to rebuild the autoconf
2987 scripts. It is not required to simply build rsync.
