1 NEWS for rsync 3.0.8 (26 Mar 2011)
2 Protocol: 30 (unchanged)
7 - Fixed two buffer-overflow issues: one where a directory path that is
8 exactly MAXPATHLEN was not handled correctly, and one handling a
9 --backup-dir that is extra extra large.
11 - Fixed a data-corruption issue when preserving hard-links without
12 preserving file ownership, and doing deletions either before or during
13 the transfer (CVE-2011-1097). This fixes some assert errors in the
14 hard-linking code, and some potential failed checksums (via -c) that
17 - Fixed a potential crash when an rsync daemon has a filter/exclude list
18 and the transfer is using ACLs or xattrs.
20 - Fixed a hang if a really large file is being processed by an rsync that
21 can't handle 64-bit numbers. Rsync will now complain about the file
22 being too big and skip it.
24 - For devices and special files, we now avoid gathering useless ACL and/or
25 xattr information for files that aren't being copied. (The un-copied
26 files are still put into the file list, but there's no need to gather
27 data that is not going to be used.) This ensures that if the user uses
28 --no-D, that rsync can't possibly complain about being unable to gather
29 extended information from special files that are in the file list (but
32 - Properly handle requesting remote filenames that start with a dash. This
33 avoids a potential error where a filename could be interpreted as a
34 (usually invalid) option.
36 - Fixed a bug in the comparing of upper-case letters in file suffixes for
39 - If an rsync daemon has a module configured without a path setting, rsync
40 will now disallow access to that module.
42 - If the destination arg is an empty string, it will be treated as a
43 reference to the current directory (as 2.x used to do).
45 - If rsync was compiled with a newer time-setting function (such as
46 lutimes), rsync will fall-back to an older function (such as utimes) on a
47 system where the newer function is not around. This helps to make the
48 rsync binary more portable in mixed-OS-release situations.
50 - Fixed a batch-file writing bug that would not write out the full set of
51 compatibility flags that the transfer was using. This fixes a potential
52 protocol problem for a batch file that contains a sender-side I/O error:
53 it would have been sent in a way that the batch-reader wasn't expecting.
55 - Some improvements to the hard-linking code to ensure that device-number
56 hashing is working right, and to supply more information if the hard-link
59 - The --inplace code was improved to not search for an impossible checksum
60 position. The quadruple-verbose chunk[N] message will now mention when
61 an inplace chunk was handled by a seek rather than a read+write.
63 - Improved ACL mask handling, e.g. for Solaris.
65 - Fixed a bug that prevented --numeric-ids from disabling the translation
66 of user/group IDs for ACLs.
68 - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
69 option (e.g. --link-dest) could output an error trying to itemize the
70 changes against the alt-dest directory's xattr/ACL info but was instead
71 trying to access the not-yet-existing new destination directory.
73 - Improved xattr system-error messages to mention the full path to the
76 - The --link-dest checking for identical symlinks now avoids considering
77 attribute differences that cannot be changed on the receiver.
79 - Avoid trying to read/write xattrs on certain file types for certain OSes.
80 Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
81 NO_SPECIAL_XATTRS defines in config.h.
83 - Improved the unsafe-symlink errors messages.
85 - Fixed a bug setting xattrs on new files that aren't user writable.
87 - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
89 - Fixed a bug with --fake-super when copying files and dirs that aren't
92 - Fixed a bug where a sparse file could have its last sparse block turned
93 into a real block when rsync sets the file size (requires ftruncate).
95 - If a temp-file name is too long, rsync now avoids truncating the name in
96 the middle of adjacent high-bit characters. This prevents a potential
97 filename error if the filesystem doesn't allow a name to contain an
98 invalid multi-byte sequence.
100 - If a muli-protocol socket connection fails (i.e., when contacting a
101 daemon), we now report all the failures, not just the last one. This
102 avoids losing a relevant error (e.g. an IPv4 connection-refused error)
103 that happened before the final error (e.g. an IPv6 protocol-not-supported
106 - Generate a transfer error if we try to call chown with a -1 for a uid or
107 a gid (which is not settable).
109 - Fixed the working of --force when used with --one-file-system.
111 - Fix the popt arg parsing so that an option that doesn't take an arg will
112 reject an attempt to supply one (can configure --with-included-popt if
113 your system's popt library doesn't yet have this fix).
115 - A couple minor option tweaks to the support/rrsync script, and also some
116 regex changes that make vim highlighting happier.
118 - Fixed some issues in the support/mnt-excl script.
120 - Various manpage improvements.
124 - Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).
128 - Use lchmod() whenever it is available (not just on symlinks).
130 - A couple fixes to the socketpair_tcp() routine.
132 - Updated the helper scripts in the packaging subdirectory.
134 - Renamed configure.in to configure.ac.
136 - Fixed configure's checking for iconv routines for newer OS X versions.
138 - Fixed the testsuite/xattrs.test script on OS X.
141 NEWS for rsync 3.0.7 (31 Dec 2009)
142 Protocol: 30 (unchanged)
147 - Fixed a bogus free when using --xattrs with --backup.
149 - Avoid an error when --dry-run was trying to stat a prior hard-link file
150 that hasn't really been created.
152 - Fixed a problem with --compress (-z) where the receiving side could
153 return the error "inflate (token) returned -5".
155 - Fixed a bug where --delete-during could delete in a directory before it
156 noticed that the sending side sent an I/O error for that directory (both
157 sides of the transfer must be at least 3.0.7).
159 - Improved --skip-compress's error handling of bad character-sets and got
160 rid of a lingering debug fprintf().
162 - Fixed the daemon's conveyance of io_error value from the sender.
164 - An rsync daemon use seteuid() (when available) if it used setuid().
166 - Get the permissions right on a --fake-super transferred directory that
167 needs more owner permissions to emulate root behavior.
169 - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
170 its modifier when sending the filter rules to the remote rsync.
172 - Improved the "--delete does not work without -r or -d" message.
174 - Improved rsync's handling of --timeout to avoid a weird timeout case
175 where the sender could timeout even though it has recently written data
176 to the socket (but hasn't read data recently, due to the writing).
178 - Some misc manpage improvements.
180 - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
182 - Make sure that a timeout specified in the daemon's config is used as a
183 maximum timeout value when the user also specifies a timeout.
185 - Improved the error-exit reporting when rsync gets an error trying to
186 cleanup after an error: the initial error is reported.
188 - Improved configure's detection of IPv6 for solaris and cygwin.
190 - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
192 - Made our (only used if missing) getaddrinfo() routine use inet_pton()
193 (which we also provide) instead of inet_aton().
195 - The exit-related debug messages now mention the program's role so it is
196 clear who output what message.
200 - Got rid of type-punned compiler warnings output by newer gcc versions.
202 - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
204 - The testsuite no longer uses "id -u", so it works better on solaris.
207 NEWS for rsync 3.0.6 (8 May 2009)
208 Protocol: 30 (unchanged)
213 - Fixed a --read-batch hang when rsync is reading a batch file that was
214 created from an incremental-recursion transfer.
216 - Fixed the daemon's socket code to handle the simultaneous arrival of
217 multiple connections.
219 - Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
220 have consecutive slashes in the value.
222 - Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
224 - The sender now skips a (bogus) symlink that has a 0-length value, which
225 avoids a transfer error in the receiver.
227 - Fixed a case where the sender could die with a tag-0 error if there was
228 an I/O during the sending of the file list.
230 - Fixed the rrsync script to avoid a server-side problem when -e is at the
231 start of the short options.
233 - Fixed a problem where a vanished directory could turn into an exit code
234 23 instead of the proper exit code 24.
236 - Fixed the --iconv conversion of symlinks when doing a local copy.
238 - Fixed a problem where --one-file-system was not stopping deletions on the
239 receiving side when a mount-point directory did not match a directory in
242 - Fixed the dropping of an ACL mask when no named ACL values were present.
244 - Fixed an ACL/xattr corruption issue where the --backup option could cause
245 rsync to associate the wrong ACL/xattr information with received files.
247 - Fixed the use of --xattrs with --only-write-batch.
249 - Fixed the use of --dry-run with --read-batch.
251 - Fixed configure's erroneous use of target.
253 - Fixed configure's --disable-debug option.
255 - Fixed a run-time issue for systems that can't find iconv_open() by adding
256 the --disable-iconv-open configure option.
258 - Complain and die if the user tries to combine --remove-source-files (or
259 the deprecated --remove-sent-files) with --read-batch.
261 - Fixed an failure transferring special files from Solaris to Linux.
264 NEWS for rsync 3.0.5 (28 Dec 2008)
265 Protocol: 30 (unchanged)
270 - Initialize xattr data in a couple spots in the hlink code, which avoids a
271 crash when the xattr pointer's memory happens to start out non-zero.
272 Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
274 - Don't send a bogus "-" option to an older server if there were no short
277 - Fixed skipping of unneeded updates in a batch file when incremental
278 recursion is active. Added a test for this. Made batch-mode handle
279 "redo" files properly (and without hanging).
281 - Fix the %P logfile escape when the daemon logs from inside a chroot.
283 - Fixed the use of -s (--protect-args) when used with a remote source or
284 destination that had an empty path (e.g. "host:"). Also fixed a problem
285 when -s was used when accessing a daemon via a remote-shell.
287 - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from
288 file when the root of the transfer isn't the current directory.
290 - Fixed a bug with "-K --delete" removing symlinks to directories when
291 incremental recursion is active.
293 - Fixed a hard to trigger hang when using --remove-source-files.
295 - Got rid of an annoying delay when accessing a daemon via a remote-shell.
297 - Properly ignore (superfluous) source args on a --read-batch command.
299 - Improved the manpage's description of the '*' wildcard to remove the
300 confusing "non-empty" qualifier.
302 - Fixed reverse lookups in the compatibility-library version of
305 - Fixed a bug when using --sparse on a sparse file that has over 2GB of
306 consecutive sparse data.
308 - Avoid a hang when using at least 3 --verbose options on a transfer with a
309 client sender (which includes local copying).
311 - Fixed a problem with --delete-delay reporting an error when it was ready
312 to remove a directory that was now gone.
314 - Got rid of a bunch of "warn_unused_result" compiler warnings.
316 - If an ftruncate() on a received file fails, it now causes a partial-
319 - Allow a path with a leading "//" to be preserved (CYGWIN only).
323 - Made the support/atomic-rsync script able to perform a fully atomic
324 update of the copied hierarchy when the destination is setup using a
325 particular symlink idiom.
328 NEWS for rsync 3.0.4 (6 Sep 2008)
329 Protocol: 30 (unchanged)
334 - Fixed a bug in the hard-linking code where it would sometimes try to
335 allocate 0 bytes of memory (which fails on some OSes, such as AIX).
337 - Fixed the hard-linking of files from a device that has a device number
338 of 0 (which seems to be a common device number on NetBSD).
340 - Fixed the handling of a --partial-dir that cannot be created. This
341 particularly impacts the --delay-updates option (since the files cannot
342 be delayed without a partial-dir), and was potentially destructive if
343 the --remove-source-files was also specified.
345 - Fixed a couple issues in the --fake-super handling of xattrs when the
346 destination files have root-level attributes (e.g. selinux values) that
347 a non-root copy can't affect.
349 - Improved the keep-alive check in the generator to fire consistently in
350 incremental-recursion mode when --timeout is enabled.
352 - The --iconv option now converts the content of a symlink too, instead
353 of leaving it in the wrong character-set (requires 3.0.4 on both sides
356 - When using --iconv, if a filename fails to convert on the receiving side,
357 this no longer makes deletions in the root-dir of the transfer fail
358 silently (the user now gets a warning about deletions being disabled
359 due to IO error as long as --ignore-errors was not specified).
361 - When using --iconv, if a server-side receiver can't convert a filename,
362 the error message sent back to the client no longer mangles the name
363 with the wrong charset conversion.
365 - Fixed a potential alignment issue in the IRIX ACL code when allocating
366 the initial "struct acl" object. Also, cast mallocs to avoid warnings.
368 - Changed some errors that were going to stdout to go to stderr.
370 - Made human_num() and human_dnum() able to output a negative number
371 (rather than outputting a cryptic string of punctuation).
375 - Rsync will avoid sending an -e option to the server if an older protocol
376 is requested (and thus the option would not be useful). This lets the
377 user specify the --protocol=29 option to access an overly-restrictive
378 server that is rejecting the protocol-30 use of -e to the server.
380 - Improved the message output for an RERR_PARTIAL exit.
384 - The Makefile will not halt for just a timestamp change on the Makefile
385 or the configure files, only for actual changes in content.
387 - Changed some commands in the testsuite's xattrs.test that called "rsync"
390 - Enhanced the release scripts to be able to handle a branch release and
391 to do even more consistency checks on the files.
394 NEWS for rsync 3.0.3 (29 Jun 2008)
395 Protocol: 30 (unchanged)
400 - Fixed a wildcard matching problem in the daemon when a module has
401 "use chroot" enabled.
403 - Fixed a crash bug in the hard-link code.
405 - Fixed the sending of xattr directory information when the code finds a
406 --link-dest or --copy-dest directory with unchanged xattrs -- the
407 destination directory now gets these unchanged xattrs properly applied.
409 - Fixed an xattr-sending glitch that could cause an "Internal abbrev"
412 - Fixed the combination of --xattrs and --backup.
414 - The generator no longer allows a '.' dir to be excluded by a daemon-
417 - Fixed deletion handling when copying a single, empty directory (with no
418 files) to a differently named, non-existent directory.
420 - Fixed the conversion of spaces into dashes in the %M log escape.
422 - Fixed several places in the code that were not returning the right
423 errno when a function failed.
425 - Fixed the backing up of a device or special file into a backup dir.
427 - Moved the setting of the socket options prior to the connect().
429 - If rsync exits in the middle of a --progress output, it now outputs a
430 newline to help prevent the progress line from being overwritten.
432 - Fixed a problem with how a destination path with a trailing slash or
433 a trailing dot-dir was compared against the daemon excludes.
435 - Fixed the sending of large (size > 16GB) files when talking to an older
436 rsync (protocols < 30): we now use a compatible block size limit.
438 - If a file's length is so huge that we overflow a checksum buffer count
439 (i.e. several hundred TB), warn the user and avoid sending an invalid
440 checksum struct over the wire.
442 - If a source arg is excluded, --relative no longer adds the excluded
443 arg's implied dirs to the transfer. This fix also made the exclude
444 check happen in the better place in the sending code.
446 - Use the overflow_exit() function for overflows, not out_of_memory().
448 - Improved the code to better handle a system that has only 32-bit file
453 - The rsyncd.conf manpage now consistently refers to the parameters in
454 the daemon config file as "parameters".
456 - The description of the --inplace option was improved.
460 - Added a new script in the support directory, deny-rsync, which allows
461 an admin to (temporarily) replace the rsync command with a script that
462 sends an error message to the remote client via the rsync protocol.
466 - Fixed a testcase failure if the tests are run as root and made some
467 compatibility improvements.
469 - Improved the daemon tests, including checking module comments, the
470 listing of files, and the ensuring that daemon excludes can't affect
473 - Improved some build rules for those that build in a separate directory
474 from the source, including better install rules for the man pages, and
475 the fixing of a proto.h-tstamp rule that could make the binaries get
476 rebuild without cause.
478 - Improved the testsuite to work around a problem with some utilities
479 (e.g. cp -p & touch -r) rounding sub-second timestamps.
481 - Ensure that the early patches don't cause any generated-file hunks to
482 bleed-over into patches that follow.
485 NEWS for rsync 3.0.2 (8 Apr 2008)
486 Protocol: 30 (unchanged)
491 - Fixed a potential buffer overflow in the xattr code.
499 - The RPM spec file was improved to install more useful files.
501 - A few developer-oriented scripts were moved from the support dir
502 to the packaging dir.
505 NEWS for rsync 3.0.1 (3 Apr 2008)
506 Protocol: 30 (unchanged)
509 NOTABLE CHANGES IN BEHAVIOR:
511 - Added the 'c'-flag to the itemizing of non-regular files so that the
512 itemized output doesn't get hidden if there were no attribute changes,
513 and also so that the itemizing of a --copy-links run will distinguish
514 between copying an identical non-regular file and the creation of a
515 revised version with a new value (e.g. a changed symlink referent, a
516 new device number, etc.).
520 - Fixed a crash bug when a single-use rsync daemon (via remote shell) was
521 run without specifying a --config=FILE option.
523 - Fixed a crash when backing up a directory that has a default ACL.
525 - Fixed a bug in the handling of xattr values that could cause rsync to
526 not think that a file's extended attributes are up-to-date.
528 - Fixed the working of --fake-super with --link-dest and --xattrs.
530 - Fixed a hang when combining --dry-run with --remove-source-files.
532 - Fixed a bug with --iconv's handling of files that cannot be converted:
533 a failed name can no longer cause a transfer failure.
535 - Fixed the building of the rounding.h file on systems that need custom
536 CPPFLAGS to be used. Also improved the error reporting if the building
539 - Fixed the use of the --protect-args (-s) option when talking to a daemon.
541 - Fixed the --ignore-existing option's protection of files on the receiver
542 that are non-regular files on the sender (e.g. if a symlink or a dir on
543 the sender is trying to replace a file on the receiver). The reverse
544 protection (protecting a dir/symlink/device from being replaced by a
545 file) was already working.
547 - Fixed an assert failure if --hard-links is combined with an option that
548 can skip a file in a set of hard-linked files (i.e. --ignore-existing,
549 --append, etc.), without skipping all the files in the set.
551 - Avoid setting the modify time on a directory that already has the right
552 modify time set. This avoids tweaking the dir's ctime.
554 - Improved the daemon-exclude handling to do a better job of applying the
555 exclude rules to path entries. It also sends the user an error just as
556 if the files were actually missing (instead of silently ignoring the
557 user's args), and avoids sending the user the filter-action messages
558 for these non-user-initiated rules.
560 - Fixed some glitches with the dry-run code's missing-directory
561 handling, including a problem when combined with --fuzzy.
563 - Fixed some glitches with the skipped-directory handling.
565 - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
567 - Fixed a glitch in the itemizing of permissions with the -E option.
569 - The --append option's restricting of transfers to those that add data no
570 longer prevents the updating of non-content changes to otherwise up-to-
571 date files (i.e. those with the same content but differing permissions,
572 ownership, xattrs, etc.).
574 - Don't allow --fake-super to be specified with -XX (double --xattrs)
575 because the options conflict. If a daemon has "fake super" enabled,
576 it automatically downgrades a -XX request to -X.
578 - Fixed a couple bugs in the parsing of daemon-config excludes that could
579 make a floating exclude rule get treated as matching an absolute path.
581 - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
582 wasn't compiled in to the daemon (avoiding a warning in the logs).
584 - Fixed the inclusion of per-dir merge files from implied dirs.
586 - Fixed the support/rrsync script to work with the latest options that
587 rsync sends (including its flag-specifying use of -e to the server).
591 - Added the --old-dirs (--old-d) option to make it easier for a user to
592 ask for file-listings with older rsync versions (this is easier than
593 having to type "-r --exclude='/*/*'" manually).
595 - When getting an error while asking an older rsync daemon for a file
596 listing, rsync will try to notice if the error is a rejection of the
597 --dirs (-d) option and let the user know how to work around the issue.
599 - Added a few more --no-OPTION overrides.
601 - Improved the documentation of the --append option.
603 - Improved the documentation of the filter/exclude/include daemon
608 - Fixed a couple minor bugs in the included popt library (ones which I
609 sent to the official popt project for inclusion in the 1.14 release).
611 - Fixed a stat() call that should have been do_stat() so that the proper
612 normal/64-bit stat() function gets called. (Was in an area that should
613 not have caused problems, though.)
615 - Changed the file-glob code to do a directory scan without using the
616 "glob" and "glob.h". This lets us do the globbing with less memory
617 churn, and also avoid adding daemon-excluded items to the returned
622 - The configure script tries to get the user's compiler to not warn about
623 unused function parameters if the build is not including one or more of
624 the ACL/xattrs/iconv features.
626 - The configure script now has better checks for figuring out if the
627 included popt code should be used or not.
629 - Fixed two testsuite glitches: avoid a failure if someone's "cd" command
630 outputs the current directory when cd-ing to a relative path, and made
631 the itemized test query how rsync was built to determine if it should
632 expect hard-linked symlinks or not.
634 - Updated the testsuite to verify that various bug fixes remain fixed.
636 - The RPM spec file was updated to have: (1) comments for how to use the
637 rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
639 - Updated the build scripts to work with a revised FTP directory
643 NEWS for rsync 3.0.0 (1 Mar 2008)
644 Protocol: 30 (changed)
647 NOTABLE CHANGES IN BEHAVIOR:
649 - The handling of implied directories when using --relative has changed to
650 send them as directories (e.g. no implied dir is ever sent as a symlink).
651 This avoids unexpected behavior and should not adversely affect most
652 people. If you're one of those rare individuals who relied upon having
653 an implied dir be duplicated as a symlink, you should specify the
654 transfer of the symlink and the transfer of the referent directory as
655 separate args. (See also --keep-dirlinks and --no-implied-dirs.)
656 Also, exclude rules no longer have a partial effect on implied dirs.
658 - Requesting a remote file-listing without specifying -r (--recursive) now
659 sends the -d (--dirs) option to the remote rsync rather than sending -r
660 along with an extra exclude of /*/*. If the remote rsync does not
661 understand the -d option (i.e. it is 2.6.3 or older), you will need to
662 either turn off -d (--no-d), or specify -r --exclude='/*/*' manually.
664 - In --dry-run mode, the last line of the verbose summary text is output
665 with a "(DRY RUN)" suffix to help remind you that no updates were made.
666 Similarly, --only-write-batch outputs "(BATCH ONLY)".
668 - A writable rsync daemon with "use chroot" disabled now defaults to a
669 symlink-munging behavior designed to make symlinks safer while also
670 allowing absolute symlinks to be stored and retrieved. This also has
671 the effect of making symlinks unusable while they're in the daemon's
672 hierarchy. See the daemon's "munge symlinks" parameter for details.
674 - Starting up an extra copy of an rsync daemon will not clobber the pidfile
675 for the running daemon -- if the pidfile exists, the new daemon will exit
676 with an error. This means that your wrapper script that starts the rsync
677 daemon should be made to handle lock-breaking (if you want any automatic
678 breaking of locks to be done).
682 - A daemon with "use chroot = no" and excluded items listed in the daemon
683 config file now properly checks an absolute-path arg specified for these
684 options: --compare-dest, --link-dest, --copy-dest, --partial-dir,
685 --backup-dir, --temp-dir, and --files-from.
687 - A daemon can now be told to disable all user- and group-name translation
688 on a per-module basis. This avoids a potential problem with a writable
689 daemon module that has "use chroot" enabled -- if precautions weren't
690 taken, a user could try to add a missing library and get rsync to use
691 it. This makes rsync safer by default, and more configurable when id-
692 translation is not desired. See the daemon's "numeric ids" parameter
695 - A chroot daemon can now indicate which part of its path should affect the
696 chroot call, and which part should become an inside-chroot path for the
697 module. This allows you to have outside-the-transfer paths (such as for
698 libraries) even when you enable chroot protection. The idiom used in the
699 rsyncd.conf file is: path = /chroot/dirs/./dirs/inside
701 - If a file's data arrived successfully on the receiving side but the
702 rename of the temporary file to the destination file failed AND the
703 --remove-source-files (or the deprecated --remove-sent-files) option
704 was specified, rsync no longer erroneously removes the associated
707 - Fixed the output of -ii when combined with one of the --*-dest options:
708 it now itemizes all the items, not just the changed ones.
710 - Made the output of all file types consistent when using a --*-dest
711 option. Prior versions would output too many creation events for
714 - The code that waits for a child pid now handles being interrupted by a
715 signal. This fixes a problem with the pre-xfer exec function not being
716 able to get the exit status from the script.
718 - A negated filter rule (i.e. with a '!' modifier) no longer loses the
719 negation when sending the filter rules to the remote rsync.
721 - Fixed a problem with the --out-format (aka --log-format) option %f: it
722 no longer outputs superfluous directory info for a non-daemon rsync.
724 - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
725 files (which includes local copies). Version 2.6.9 would complete the
726 copy, but exit with an error when the receiver output its memory stats.
728 - If --password-file is used on a non-daemon transfer, rsync now complains
729 and exits. This should help users figure out that they can't use this
730 option to control a remote shell's password prompt.
732 - Make sure that directory permissions of a newly-created destination
733 directory are handled right when --perms is left off.
735 - The itemized output of a newly-created destination directory is now
736 output as a creation event, not a change event.
738 - Improved --hard-link so that more corner cases are handled correctly
739 when combined with options such as --link-dest and/or --ignore-existing.
741 - The --append option no longer updates a file that has the same size.
743 - Fixed a bug when combining --backup and --backup-dir with --inplace:
744 any missing backup directories are now created.
746 - Fixed a bug when using --backup and --inplace with --whole-file or
747 --read-batch: backup files are actually created now.
749 - The daemon pidfile is checked and created sooner in the startup sequence.
751 - If a daemon module's "path" value is not an absolute pathname, the code
752 now makes it absolute internally (making it work properly).
754 - Ensure that a temporary file always has owner-write permission while we
755 are writing to it. This avoids problems with some network filesystems
756 when transfering read-only files.
758 - Any errors output about password-file reading no longer cause an error at
759 the end of the run about a partial transfer.
761 - The --read-batch option for protocol 30 now ensures that several more
762 options are set correctly for the current batch file: --iconv, --acls,
763 --xattrs, --inplace, --append, and --append-verify.
765 - Using --only-write-batch to a daemon receiver now works properly (older
766 versions would update some files while writing the batch).
768 - Avoid outputting a "file has vanished" message when the file is a broken
769 symlink and --copy-unsafe-links or --copy-dirlinks is used (the code
770 already handled this for --copy-links).
772 - Fixed the combination of --only-write-batch and --dry-run.
774 - Fixed rsync's ability to remove files that are not writable by the file's
775 owner when rsync is running as the same user.
777 - When transferring large files, the sender's hashtable of checksums is
778 kept at a more reasonable state of fullness (no more than 80% full) so
779 that the scanning of the hashtable will not bog down as the number of
784 - A new incremental-recursion algorithm is now used when rsync is talking
785 to another 3.x version. This starts the transfer going more quickly
786 (before all the files have been found), and requires much less memory.
787 See the --recursive option in the manpage for some restrictions.
789 - Lowered memory use in the non-incremental-recursion algorithm for typical
790 option values (usually saving from 21-29 bytes per file).
792 - The default --delete algorithm is now --delete-during when talking to a
793 3.x rsync. This is a faster scan than using --delete-before (which is
794 the default when talking to older rsync versions), and is compatible with
795 the new incremental recursion mode.
797 - Rsync now allows multiple remote-source args to be specified rather than
798 having to rely on a special space-splitting side-effect of the remote-
799 shell. Additional remote args must specify the same host or an empty one
800 (e.g. empty: :file1 or ::module/file2). For example, this means that
801 local use of brace expansion now works: rsync -av host:dir/{f1,f2} .
803 - Added the --protect-args (-s) option, that tells rsync to send most of
804 the command-line args at the start of the transfer rather than as args
805 to the remote-shell command. This protects them from space-splitting,
806 and only interprets basic wildcard special shell characters (*?[).
808 - Added the --delete-delay option, which is a more efficient way to delete
809 files at the end of the transfer without needing a separate delete pass.
811 - Added the --acls (-A) option to preserve Access Control Lists. This is
812 an improved version of the prior patch that was available, and it even
813 supports OS X ACLs. If you need to have backward compatibility with old,
814 ACL-patched versions of rsync, apply the acls.diff file from the patches
817 - Added the --xattrs (-X) option to preserve extended attributes. This is
818 an improved version of the prior patch that was available, and it even
819 supports OS X xattrs (which includes their resource fork data). If you
820 need to have backward compatibility with old, xattr-patched versions of
821 rsync, apply the xattrs.diff file from the patches dir.
823 - Added the --fake-super option that allows a non-super user to preserve
824 all attributes of a file by using a special extended-attribute idiom.
825 It even supports the storing of foreign ACL data on your backup server.
826 There is also an analogous "fake super" parameter for an rsync daemon.
828 - Added the --iconv option, which allows rsync to convert filenames from
829 one character-set to another during the transfer. The default is to
830 make this feature available as long as your system has iconv_open().
831 If compilation fails, specify --disable-iconv to configure, and then
832 rebuild. If you want rsync to perform character-set conversions by
833 default, you can specify --enable-iconv=CONVERT_STRING with the default
834 value for the --iconv option that you wish to use. For example,
835 "--enable-iconv=." is a good choice. See the rsync manpage for an
836 explanation of the --iconv option's settings.
838 - A new daemon config parameter, "charset", lets you control the character-
839 set that is used during an --iconv transfer to/from a daemon module. You
840 can also set your daemon to refuse "no-iconv" if you want to force the
841 client to use an --iconv transfer (requiring an rsync 3.x client).
843 - Added the --skip-compress=LIST option to override the default list of
844 file suffixes that will not be compressed when using --compress (-z).
846 - The daemon's default for "dont compress" was extended to include:
847 *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
848 The name-matching routine was also optimized to run more quickly.
850 - The --max-delete option now outputs a warning if it skipped any file
851 deletions, including a count of how many deletions were skipped. (Older
852 versions just silently stopped deleting things.)
854 - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
855 about extraneous files without deleting anything. If you're not sure
856 what version the client is, you can use the less-obvious --max-delete=-1,
857 as both old and new versions will treat that as the same request (though
858 older versions don't warn).
860 - The --hard-link option now uses less memory on both the sending and
861 receiving side for all protocol versions. For protocol 30, the use of a
862 hashtable on the sending side allows us to more efficiently convey to the
863 receiver what files are linked together. This reduces the amount of data
864 sent over the socket by a considerable margin (rather than adding more
865 data), and limits the in-memory storage of the device+inode information
866 to just the sending side for the new protocol 30, or to the receiving
867 side when speaking an older protocol (note that older rsync versions kept
868 the device+inode information on both sides).
870 - The filter rules now support a perishable ("p") modifier that marks rules
871 that should not have an effect in a directory that is being deleted. e.g.
872 -f '-p .svn/' would only affect "live" .svn directories.
874 - Rsync checks all the alternate-destination args for validity (e.g.
875 --link-dest). This lets the user know when they specified a directory
878 - If we get an ENOSYS error setting the time on a symlink, we don't
879 complain about it anymore (for those systems that even support the
880 setting of the modify-time on a symlink).
882 - Protocol 30 now uses MD5 checksums instead of MD4.
884 - Changed the --append option to not checksum the existing data in the
885 destination file, which speeds up file appending.
887 - Added the --append-verify option, which works like the older --append
888 option (verifying the existing data in the destination file). For
889 compatibility with older rsync versions, any use of --append that is
890 talking protocol 29 or older will revert to the --append-verify method.
892 - Added the --contimeout=SECONDS option that lets the user specify a
893 connection timeout for rsync daemon access.
895 - Documented and extended the support for the RSYNC_CONNECT_PROG variable
896 that can be used to enhance the client side of a daemon connection.
898 - Improved the dashes and double-quotes in the nroff manpage output.
900 - Rsync now supports a lot more --no-OPTION override options.
904 - The file-list sorting algorithm now uses a sort that keeps any same-
905 named items in the same order as they were specified. This allows
906 rsync to always ensure that the first of the duplicates is the one
907 that will be included in the copy. The new sort is also faster
908 than the glibc version of qsort() and mergesort().
910 - Rsync now supports the transfer of 64-bit timestamps (time_t values).
912 - Made the file-deletion code use a little less stack when recursing
913 through a directory hierarchy of extraneous files.
915 - Fixed a build problem with older (2.x) versions of gcc.
917 - Added some isType() functions that make dealing with signed characters
918 easier without forcing variables via casts.
920 - Changed strcat/strcpy/sprintf function calls to use safer versions.
922 - Upgraded the included popt version to 1.10.2 and improved its use of
923 string-handling functions.
925 - Added missing prototypes for compatibility functions from the lib dir.
927 - Configure determines if iconv() has a const arg, allowing us to avoid a
930 - Made the sending of some numbers more efficient for protocol 30.
932 - Make sure that a daemon process doesn't mind if the client was weird and
933 omitted the --server option.
935 - There are more internal logging categories available in protocol 30 than
936 the age-old FINFO and FERROR, including FERROR_XFER and FWARN. These new
937 categories allow some errors and warnings to go to stderr without causing
938 an erroneous end-of-run warning about some files not being able to be
941 - Improved the use of "const" on pointers.
943 - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
944 older sections of a pool's memory.
946 - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
947 some new code (derived from samba, derived from PostgreSQL) that has a
948 better license than the old code.
952 - Rsync is now licensed under the GPLv3 or later.
954 - Rsync is now being maintained in a "git" repository instead of CVS
955 (though the old CVS repository still exists for historical access).
956 Several maintenance scripts were updated to work with git.
958 - Generated files are no longer committed into the source repository. The
959 autoconf and autoheader commands are now automatically run during the
960 normal use of "configure" and "make". The latest dev versions of all
961 generated files can also be copied from the samba.org web site (see the
962 prepare-source script's fetch option).
964 - The "patches" directory of diff files is now built from branches in the
965 rsync git repository (branch patch/FOO creates file patches/FOO.diff).
966 This directory is now distributed in a separate separate tar file named
967 rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
969 - The proto.h file is now built using a simple perl script rather than a
970 complex awk script, which proved to be more widely compatible.
972 - When running the tests, we now put our per-test temp dirs into a sub-
973 directory named testtmp (which is created, if missing). This allows
974 someone to symlink the testtmp directory to another filesystem (which is
975 useful if the build dir's filesystem does not support ACLs and xattrs,
976 but another filesystem does).
978 - Rsync now has a way of handling protocol-version changes during the
979 development of a new protocol version. This causes any out-of-sync
980 versions to speak an older protocol rather than fail in a cryptic manner.
981 This addition makes it safer to deploy a pre-release version that may
982 interact with the public. This new exchange of sub-version info does not
983 interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
984 does not have enough range to allow the main protocol number to be
985 incremented for every minor tweak in that happens during development).
987 - The csprotocol.txt file was updated to mention the daemon protocol change
988 in the 3.0.0 release.
991 NEWS for rsync 2.6.9 (6 Nov 2006)
992 Protocol: 29 (unchanged)
997 - If rsync is interrupted via a handled signal (such as SIGINT), it will
998 once again clean-up its temp file from the destination dir.
1000 - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
1001 --copy-dest, and --compare-dest options to a daemon without chroot: if
1002 the copy's destination dir is deeper than the top of the module's path,
1003 these options now accept a safe number of parent-dir (../) references
1004 (since these options are relative to the destination dir). The old code
1005 incorrectly chopped off all "../" prefixes for these options, no matter
1006 how deep the destination directory was in the module's hierarchy.
1008 - Fixed a bug where a deferred info/error/log message could get sent
1009 directly to the sender instead of being handled by rwrite() in the
1010 generator. This fixes an "unexpected tag 3" fatal error, and should
1011 also fix a potential problem where a deferred info/error message from
1012 the receiver might bypass the log file and get sent only to the client
1013 process. (These problems could only affect an rsync daemon that was
1016 - Fixed a bug when --inplace was combined with a --*-dest option and we
1017 update a file's data using an alternate basis file. The code now
1018 notices that it needs to copy the matching data from the basis file
1019 instead of (wrongly) assuming that it was already present in the file.
1021 - Fixed a bug where using --dry-run with a --*-dest option with a path
1022 relative to a directory that does not yet exist: the affected option
1023 gets its proper path value so that the output of the dry-run is right.
1025 - Fixed a bug in the %f logfile escape when receiving files: the
1026 destination path is now included in the output (e.g. you can now tell
1027 when a user specifies a subdir inside a module).
1029 - If the receiving side fails to create a directory, it will now skip
1030 trying to update everything that is inside that directory.
1032 - If --link-dest is specified with --checksum but without --times, rsync
1033 will now allow a hard-link to be created to a matching link-dest file
1034 even when the file's modify-time doesn't match the server's file.
1036 - The daemon now calls more timezone-using functions prior to doing a
1037 chroot. This should help some C libraries to generate proper timestamps
1038 from inside a chrooted daemon (and to not try to access /etc/timezone
1039 over and over again).
1041 - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
1042 it now deletes an alternate basis file from the partial-dir that was used
1043 to successfully update a destination file.
1045 - Fixed a bug in the handling of --delete-excluded when using a per-dir
1046 merge file: the merge file is now honored on the receiving side, and
1047 only its unqualified include/exclude commands are ignored (just as is
1048 done for global include/excludes).
1050 - Fixed a recent bug where --delete was not working when transferring from
1051 the root (/) of the filesystem with --relative enabled.
1053 - Fixed a recent bug where an --exclude='*' could affect the root (/) of
1054 the filesystem with --relative enabled.
1056 - When --inplace creates a file, it is now created with owner read/write
1057 permissions (0600) instead of no permissions at all. This avoids a
1058 problem continuing a transfer that was interrupted (since --inplace
1059 will not update a file that has no write permissions).
1061 - If either --remove-source-files or --remove-sent-files is enabled and we
1062 are unable to remove the source file, rsync now outputs an error.
1064 - Fixed a bug in the daemon's "incoming chmod" rule: newly-created
1065 directories no longer get the 'F' (file) rules applied to them.
1067 - Fixed an infinite loop bug when a filter rule was rejected due to being
1070 - When the server receives a --partial-dir option from the client, it no
1071 longer runs the client-side code that adds an assumed filter rule (since
1072 the client will be sending us the rules in the usual manner, and they
1073 may have chosen to override the auto-added rule).
1077 - Added the --log-file=FILE and --log-file-format=FORMAT options. These
1078 can be used to tell any rsync to output what it is doing to a log file.
1079 They work with a client rsync, a non-daemon server rsync (see the man
1080 page for instructions), and also allows the overriding of rsyncd.conf
1081 settings when starting a daemon.
1083 - The --log-format option was renamed to be --out-format to avoid confusing
1084 it with affecting the log-file output. (The old option remains as an
1085 alias for the new to preserve backward compatibility.)
1087 - Made "log file" and "syslog facility" settable on a per-module basis in
1088 the daemon's config file.
1090 - Added the --remove-source-files option as a replacement for the (now
1091 deprecated) --remove-sent-files option. This new option removes all
1092 non-dirs from the source directories, even if the file was already
1093 up-to-date. This fixes a problem where interrupting an rsync that
1094 was using --remove-sent-files and restarting it could leave behind
1095 a file that the earlier rsync synchronized, but didn't get to remove.
1096 (The deprecated --remove-sent-files is still understood for now, and
1097 still behaves in the same way as before.)
1099 - Added the option --no-motd to suppress the message-of-the-day output
1100 from a daemon when doing a copy. (See the manpage for a caveat.)
1102 - Added a new environment variable to the pre-/post-xfer exec commands (in
1103 the daemon's config file): RSYNC_PID. This value will be the same in
1104 both the pre- and post-xfer commands, so it can be used as a unique ID
1105 if the pre-xfer command wants to cache some arg/request info for the
1110 - Did a code audit using IBM's code-checker program and made several
1111 changes, including: replacing most of the strcpy() and sprintf()
1112 calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
1113 an enum that had been intermingling a literal 0 with the defined enum
1114 values, silencing some uninitialized memory checks, marking some
1115 functions with a "noreturn" attribute, and changing an "if" that
1116 could never succeed on some platforms into a pre-processor directive
1117 that conditionally compiles the code.
1119 - Fixed a potential bug in f_name_cmp() when both the args are a
1120 top-level "." dir (which doesn't happen in normal operations).
1122 - Changed exit_cleanup() so that it can never return instead of exit.
1123 The old code might return if it found the exit_cleanup() function
1124 was being called recursively. The new code is segmented so that
1125 any recursive calls move on to the next step of the exit-processing.
1127 - The macro WIFEXITED(stat) will now be defined if the OS didn't already
1132 - The acls.diff and xattrs.diff patches have received a bunch of work to
1133 make them much closer to being acceptable in the main distribution.
1134 The xattrs patch also has some preliminary Mac OS X and FreeBSD
1135 compatibility code that various system types to exchange extended
1138 - A new diff in the patches dir, fake-root.diff, allows rsync to
1139 maintain a backup hierarchy with full owner, group, and device info
1140 without actually running as root. It does this using a special
1141 extended attribute, so it depends on xattrs.diff (which depends on
1144 - The rsync.yo and rsyncd.conf.yo files have been updated to work
1145 better with the latest yodl 2.x releases.
1147 - Updated config.guess and config.sub to their 2006-07-02 versions.
1149 - Updated various files to include the latest FSF address and to have
1150 consistent opening comments.
1153 NEWS for rsync 2.6.8 (22 Apr 2006)
1154 Protocol: 29 (unchanged)
1155 Changes since 2.6.7:
1159 - Fixed a bug in the exclude code where an anchored exclude without any
1160 wildcards fails to match an absolute source arg, but only when --relative
1163 - Improved the I/O code for the generator to fix a potential hang when the
1164 receiver gets an EOF on the socket but the generator's select() call
1165 never indicates that the socket is writable for it to be notified about
1166 the EOF. (This can happen when using stunnel).
1168 - Fixed a problem with the file-reading code where a failed read (such as
1169 that caused by a bad sector) would not advance the file's read-position
1170 beyond the failed read's data.
1172 - Fixed a logging bug where the "log file" directive was not being honored
1173 in a single-use daemon (one spawned by a remote-shell connection or by
1176 - If rsync cannot honor the --delete option, we output an error and exit
1177 instead of silently ignoring the option.
1179 - Fixed a bug in the --link-dest code that prevented special files (such as
1180 fifos) from being linked.
1182 - The ability to hard-link symlinks and special files is now determined at
1183 configure time instead of at runtime. This fixes a bug with --link-dest
1184 creating a hard-link to a symlink's referent on a BSD system.
1188 - In daemon mode, if rsync fails to bind to the requested port, the
1189 error(s) returned by socket() and/or bind() are now logged.
1191 - When we output a fatal error, we now output the version of rsync in the
1194 - Improved the documentation for the --owner and --group options.
1196 - The rsyncstats script in "support" has an improved line-parsing regex
1197 that is easier to read and also makes it to parse syslog-generated lines.
1199 - A new script in "support": file-attr-restore, can be used to restore the
1200 attributes of a file-set (the permissions, ownership, and group info)
1201 taken from the cached output of a "find ARG... -ls" command.
1205 - Removed the unused function write_int_named(), the unused variable
1206 io_read_phase, and the rarely used variable io_write_phase. This also
1207 elides the confusing 'phase "unknown"' part of one error message.
1209 - Removed two unused configure checks and two related (also unused)
1210 compatibility functions.
1212 - The xattrs.diff patch received a security fix that prevents a potential
1213 buffer overflow in the receive_xattr() code.
1215 - The acls.diff patch has been improved quite a bit, with more to come.
1217 - A new patch was added: log-file.diff. This contains an early version of
1218 a future option, --log-file=FILE, that will allow any rsync to log its
1219 actions to a file (something that only a daemon supports at present).
1222 NEWS for rsync 2.6.7 (11 Mar 2006)
1223 Protocol: 29 (unchanged)
1224 Changes since 2.6.6:
1228 - The letter 'D' in the itemized output was being used for both devices
1229 (character or block) as well as other special files (such as fifos and
1230 named sockets). This has changed to separate non-device special files
1231 under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the
1232 "--specials" option, below.
1234 - The way rsync escapes unreadable characters has changed. First, rsync
1235 now has support for recognizing valid multibyte character sequences in
1236 your current locale, allowing it to escape fewer characters than before
1237 for a locale such as UTF-8. Second, it now uses an escape idiom of
1238 "\#123", which is the literal string "\#" followed by exactly 3 octal
1239 digits. Rsync no longer doubles a backslash character in a filename
1240 (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
1241 escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
1242 (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also
1243 the --8-bit-output (-8) option, mentioned below.
1245 Script writers: the local rsync is the one that outputs escaped names,
1246 so if you need to support unescaping of filenames for older rsyncs, I'd
1247 suggest that you parse the output of "rsync --version" and only use the
1248 old unescaping rules for 2.6.5 and 2.6.6.
1252 - Fixed a really old bug that caused --checksum (-c) to checksum all the
1253 files encountered during the delete scan (ouch).
1255 - Fixed a potential hang in a remote generator: when the receiver gets a
1256 read-error on the socket, it now signals the generator about this so that
1257 the generator does not try to send any of the terminating error messages
1258 to the client (avoiding a potential hang in some setups).
1260 - Made hard-links work with symlinks and devices again.
1262 - If the sender gets an early EOF reading a source file, we propagate this
1263 error to the receiver so that it can discard the file and try requesting
1264 it again (which is the existing behavior for other kinds of read errors).
1266 - If a device-file/special-file changes permissions, rsync now updates the
1267 permissions without recreating the file.
1269 - If the user specifies a remote-host for both the source and destination,
1270 we now output a syntax error rather than trying to open the destination
1271 hostspec as a filename.
1273 - When --inplace creates a new destination file, rsync now creates it with
1274 permissions 0600 instead of 0000 -- this makes restarting possible when
1275 the transfer gets interrupted in the middle of sending a new file.
1277 - Reject the combination of --inplace and --sparse since the sparse-output
1278 algorithm doesn't work when overwriting existing data.
1280 - Fixed the directory name in the error that is output when pop_dir()
1283 - Really fixed the parsing of a "!" entry in .cvsignore files this time.
1285 - If the generator gets a stat() error on a file, output it (this used to
1286 require at least -vv for the error to be seen).
1288 - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
1289 the exit status properly and generate a better error.
1291 - Fixed some glitches in the double-verbose output when using --copy-dest,
1292 --link-dest, or --compare-dest. Also improved how the verbose output
1293 handles hard-links (within the transfer) that had an up-to-date alternate
1294 "dest" file, and copied files (via --copy-dest).
1296 - Fixed the matching of the dont-compress items (e.g. *.gz) against files
1297 that have a path component containing a slash.
1299 - If the code reading a filter/exclude file gets an EINTR error, rsync now
1300 clears the error flag on the file handle so it can keep on reading.
1302 - If --relative is active, the sending side cleans up trailing "/" or "/."
1303 suffixes to avoid triggering a bug in older rsync versions. Also, we now
1304 reject a ".." dir if it would be sent as a relative dir.
1306 - If a non-directory is in the way of a directory and rsync is run with
1307 --dry-run and --delete, rsync no longer complains about not being able
1308 to opendir() the not-yet present directory.
1310 - When --list-only is used and a non-existent local destination dir was
1311 also specified as a destination, rsync no longer generates a warning
1312 about being unable to create the missing directory.
1314 - Fixed some problems with --relative --no-implied-dirs when the
1315 destination directory did not yet exist: we can now create a symlink or
1316 device when it is the first thing in the missing dir, and --fuzzy no
1317 longer complains about being unable to open the missing dir.
1319 - Fixed a bug where the --copy-links option would not affect implied
1320 directories without --copy-unsafe-links (see --relative).
1322 - Got rid of the need for --force to be used in some circumstances with
1323 --delete-after (making it consistent with --delete-before/-during).
1325 - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
1326 when a file is too large (rsync handles the write error).
1328 - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
1329 was not properly padded with trailing '=' chars. This only affects a
1330 user that need to use a password-authenticated proxy for an outgoing
1331 daemon-rsync connection.
1333 - If we're transferring an empty directory to a new name, rsync no longer
1334 forces S_IWUSR if it wasn't already set, nor does it accidentally leave
1337 - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
1338 checksum for the current file offset.
1340 - Rsync no longer allows a single directory to be copied over a non-
1341 directory destination arg.
1345 - Added the --append option that makes rsync append data onto files that
1346 are longer on the source than the destination (this includes new files).
1348 - Added the --min-size=SIZE option to exclude small files from the
1351 - Added the --compress-level option to allow you to set how aggressive
1352 rsync's compression should be (this option implies --compress).
1354 - Enhanced the parsing of the SIZE value for --min-size and --max-size to
1355 allow easy entry of multiples of 1000 (instead of just multiples of 1024)
1356 and off-by-one values too (e.g. --max-size=8mb-1).
1358 - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
1359 high-bit characters that it thinks are unreadable in the current locale.
1361 - The new option --human-readable (-h) changes the output of --progress,
1362 --stats, and the end-of-run summary to be easier to read. If repeated,
1363 the units become powers of 1024 instead of powers of 1000. (The old
1364 meaning of -h, as a shorthand for --help, still works as long as you
1365 just use it on its own, as in "rsync -h".)
1367 - If lutimes() and/or lchmod() are around, use them to allow the
1368 preservation of attributes on symlinks.
1370 - The --link-dest option now affects symlinks and devices (when possible).
1372 - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and
1373 "post-xfer exec". These allow a command to be specified on a per-module
1374 basis that will be run before and/or after a daemon-mode transfer. (See
1375 the man page for a list of the environment variables that are set with
1376 information about the transfer.)
1378 - When using the --relative option, you can now insert a dot dir in
1379 the source path to indicate where the replication of the source dirs
1380 should start. For example, if you specify a source path of
1381 rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
1382 replicate the "baz/dir" part of the source path (note: a trailing
1383 dot dir is unaffected unless it also has a trailing slash).
1385 - Added some new --no-FOO options that make it easier to override unwanted
1386 implied or default options. For example, "-a --no-o" (aka "--archive
1387 --no-owner") can be used to turn off the preservation of file ownership
1388 that is implied by -a.
1390 - Added the --chmod=MODE option that allows the destination permissions to
1391 be changed from the source permissions. E.g. --chmod=g+w,o-rwx
1393 - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
1394 a module to specify what permissions changes should be applied to all
1395 files copied to and from the daemon.
1397 - Allow the --temp-dir option to be specified when starting a daemon, which
1398 sets the default temporary directory for incoming files.
1400 - If --delete is combined with --dirs without --recursive, rsync will now
1401 delete in any directory whose content is being synchronized.
1403 - If --backup is combined with --delete without --backup-dir (and without
1404 --delete-excluded), we add a "protect" filter-rule to ensure that files
1405 with the backup suffix are not deleted.
1407 - The file-count stats that are output by --progress were improved to
1408 better indicate what the numbers mean. For instance, the output:
1409 "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
1410 to be transferred, and we still need to check 8383 more files out of
1413 - The include/exclude code now allows a dir/*** directive (with 3 trailing
1414 stars) to match both the dir itself as well as all the content below the
1415 dir (dir/** would not match the dir).
1417 - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
1418 discard empty chains of directories from the file-list. This makes it
1419 easier to selectively copy files from a source hierarchy and end up with
1420 just the directories needed to hold the resulting files.
1422 - If the --itemize-changes (-i) option is repeated, rsync now includes
1423 unchanged files in the itemized output (similar to -vv, but without all
1424 the other verbose messages that can get in the way). Of course, the
1425 client must be version 2.6.7 for this to work, but the remote rsync only
1426 needs to be 2.6.7 if you're pushing files.
1428 - Added the --specials option to tell rsync to copy non-device special
1429 files (which rsync now attempts even as a normal user). The --devices
1430 option now requests the copying of just devices (character and block).
1431 The -D option still requests both (e.g. --devices and --specials), -a
1432 still implies -D, and non-root users still get a silent downgrade that
1433 omits device copying.
1435 - Added the --super option to make the receiver always attempt super-user
1436 activities. This is useful for systems that allow things such as devices
1437 to be created or ownership to be set without being UID 0, and is also
1438 useful for someone who wants to ensure that errors will be output if the
1439 receiving rsync isn't being run as root.
1441 - Added the --sockopts option for those few who want to customize the TCP
1442 options used to contact a daemon rsync.
1444 - Added a way for the --temp-dir option to be combined with a partial-dir
1445 setting that lets rsync avoid non-atomic updates (for those times when
1446 --temp-dir is not being used because space is tight).
1448 - A new support script, files-to-excludes, will transform a list of files
1449 into a set of include/exclude directives that will copy those files.
1451 - A new option, --executability (-E) can be used to preserve just the
1452 execute bit on files, for those times when using the --perms option is
1455 - The daemon now logs each connection and also each module-list request
1458 - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
1459 (permission bits, e.g. "rwxr-xrwt").
1461 - The --dry-run option no longer forces the enabling of --verbose.
1463 - The --remove-sent-files option now does a better job of incrementally
1464 removing the sent files on the sending side (older versions tended to
1465 clump up all the removals at the end).
1467 - A daemon now supersedes its minimal SIGCHLD handler with the standard
1468 PID-remembering version after forking. This ensures that the generator
1469 can get the child-exit status from the receiver.
1471 - Use of the --bwlimit option no longer interferes with the remote rsync
1472 sending error messages about invalid/refused options.
1474 - Rsync no longer returns a usage error when used with one local source arg
1475 and no destination: this now implies the --list-only option, just like
1476 the comparable situation with a remote source arg.
1478 - Added the --copy-dirlinks option, a more limited version of --copy-links.
1480 - Various documentation improvements, including: a better synopsis, some
1481 improved examples, a better discussion of the presence and absence of
1482 --perms (including how it interacts with the new --executability and
1483 --chmod options), an extended discussion of --temp-dir, an improved
1484 discussion of --partial-dir, a better description of rsync's pattern
1485 matching characters, an improved --no-implied-dirs section, and the
1486 documenting of what the --stats option outputs.
1488 - Various new and updated diffs in the patches dir, including: acls.diff,
1489 xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
1493 - We now use sigaction() and sigprocmask() if possible, and fall back on
1494 signal() if not. Using sigprocmask() ensures that rsync enables all the
1495 signals that it needs, just in case it was started in a masked state.
1497 - Some buffer sizes were expanded a bit, particularly on systems where
1498 MAXPATHLEN is overly small (e.g. cygwin).
1500 - If io_printf() tries to format more data than fits in the buffer, exit
1501 with an error instead of transmitting a truncated buffer.
1503 - If a va_copy macro is defined, lib/snprintf.c will use it when defining
1506 - Reduced the amount of stack memory needed for each level of directory
1507 recursion by nearly MAXPATHLEN bytes.
1509 - The wildmatch function was extended to allow an array of strings to be
1510 supplied as the string to match. This allows the exclude code to do less
1513 - Got rid of the safe_fname() function (and all the myriad calls) and
1514 replaced it with a new function in the log.c code that filters all the
1515 output going to the terminal.
1517 - Unified the f_name() and the f_name_to() functions.
1519 - Improved the hash-table code the sender uses to handle checksums to make
1520 it use slightly less memory and run just a little faster.
1524 - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
1525 the previous -p0. Also, the version included in the release tar now
1526 affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
1527 it is no longer necessary to run autoconf and/or yodl unless you're
1528 applying a patch that was checked out from CVS.
1530 - Several diffs in the patches dir now use the proper --enable-FOO
1531 configure option instead of --with-FOO to turn on the inclusion of
1532 the newly patched feature.
1534 - There is a new script, "prepare-source" than can be used to update the
1535 various generated files (proto.h, configure, etc.) even before configure
1536 has created the Makefile (this is mainly useful when patching the source
1537 with a patch that doesn't affect generated files).
1539 - The testsuite now sets HOME so that it won't be affected by a file such
1543 NEWS for rsync 2.6.6 (28 Jul 2005)
1544 Protocol: 29 (unchanged)
1545 Changes since 2.6.5:
1549 - The zlib code was upgraded to version 1.2.3 in order to make it more
1550 secure. While the widely-publicized security problem in zlib 1.2.2 did
1551 not affect rsync, another security problem surfaced that affects rsync's
1556 - The setting of flist->high in clean_flist() was wrong for an empty list.
1557 This could cause flist_find() to crash in certain rare circumstances
1558 (e.g. if just the right directory setup was around when --fuzzy was
1559 combined with --link-dest).
1561 - The outputting of hard-linked files when verbosity was > 1 was not right:
1562 (1) Without -i it would output the name of each hard-linked file as
1563 though it had been changed; it now outputs a "is hard linked" message for
1564 the file. (2) With -i it would output all dots for the unchanged
1565 attributes of a hard-link; it now changes those dots to spaces, as is
1566 done for other totally unchanged items.
1568 - When backing up a changed symlink or device, get rid of any old backup
1569 item so that we don't get an "already exists" error.
1571 - A couple places that were comparing a local and a remote modification-
1572 time were not honoring the --modify-window option.
1574 - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
1575 set too often (if some non-significant mode bits differed).
1577 - Fixed a really old, minor bug that could cause rsync to warn about being
1578 unable to mkdir() a path that ends in "/." because it just created the
1579 directory (required --relative, --no-implied-dirs, a source path that
1580 ended in either a trailing slash or a trailing "/.", and a non-existing
1581 destination dir to tickle the bug in a recent version).
1585 - Made the "max verbosity" setting in the rsyncd.conf file settable on a
1586 per-module basis (which now matches the documentation).
1588 - The support/rrsync script has been upgraded to verify the args of options
1589 that take args (instead of rejecting any such options). The script was
1590 also changed to try to be more secure and to fix a problem in the parsing
1591 of a pull operation that has multiple sources.
1593 - Improved the documentation that explains the difference between a
1594 normal daemon transfer and a daemon-over remote-shell transfer.
1596 - Some of the diffs supplied in the patches dir were fixed and/or
1601 - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
1602 NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
1603 find in the /etc/group file).
1605 - Added a test to the test suite, itemized.test, that tests the output of
1606 -i (log-format w/%i) and some double-verbose messages.
1609 NEWS for rsync 2.6.5 (1 Jun 2005)
1610 Protocol: 29 (unchanged)
1611 Changes since 2.6.4:
1615 - Non-printable chars in filenames are now output using backslash-
1616 escaped characters rather than '?'s. Any non-printable character is
1617 output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
1618 is now output as "\\". Rsync also uses your locale setting, which
1619 can make it treat fewer high-bit characters as non-printable.
1621 - If rsync received an empty file-list when pulling files, it would
1622 output a "nothing to do" message and exit with a 0 (success) exit
1623 status, even if the remote rsync returned an error (it did not do
1624 this under the same conditions when pushing files). This was changed
1625 to make the pulling behavior the same as the pushing behavior: we
1626 now do the normal end-of-run outputting (depending on options) and
1627 exit with the appropriate exit status.
1631 - A crash bug was fixed when a daemon had its "path" set to "/", did
1632 not have chroot enabled, and used some anchored excludes in the
1635 - Fixed a bug in the transfer of a single file when -H is specified
1636 (rsync would either infinite loop or perhaps crash).
1638 - Fixed a case where the generator might try (and fail) to tweak the
1639 write-permissions of a read-only directory in list-only mode (this
1640 only caused an annoying warning message).
1642 - If --compare-dest or --link-dest uses a locally-copied file as the
1643 basis for an updated version, log this better when --verbose or -i
1646 - Fixed the accidental disabling of --backup during the --delete-after
1649 - Restored the ability to use the --address option in client mode (in
1650 addition to its use in daemon mode).
1652 - Make sure that some temporary progress information from the delete
1653 processing does not get left on the screen when it is followed by a
1656 - When --existing skips a directory with extra verbosity, refer to it
1657 as a "directory", not a "file".
1659 - When transferring a single file to a different-named file, any
1660 generator messages that are source-file related no longer refer to
1661 the file by the destination filename.
1663 - Fixed a bug where hard-linking a group of files might fail if the
1664 generator hasn't created a needed destination directory yet.
1666 - Fixed a bug where a hard-linked group of files that is newly-linked
1667 to a file in a --link-dest dir doesn't link the files from the rest
1670 - When deleting files with the --one-file-system (-x) option set, rsync
1671 no longer tries to remove files from inside a mount-point on the
1672 receiving side. Also, we don't complain about being unable to remove
1673 the mount-point dir.
1675 - Fixed a compatibility problem when using --cvs-ignore (-C) and
1676 sending files to an older rsync without using --delete.
1678 - Make sure that a "- !" or "+ !" include/exclude pattern does not
1679 trigger the list-clearing action that is reserved for "!".
1681 - Avoid a timeout in the generator when the sender/receiver aren't
1682 handling the generator's checksum output quickly enough.
1684 - Fixed the omission of some directories in the delete processing when
1685 --relative (-R) was combined with a source path that had a trailing
1688 - Fixed a case where rsync would erroneously delete some files and then
1689 re-transfer them when the options --relative (-R) and --recursive
1690 (-r) were both enabled (along with --delete) and a source path had a
1693 - Make sure that --max-size doesn't affect a device or a symlink.
1695 - Make sure that a system with a really small MAXPATHLEN does not cause
1696 the buffers in readfd_unbuffered() to be too small to receive normal
1697 messages. (This mainly affected Cygwin.)
1699 - If a source pathname ends with a filename of "..", treat it as if
1700 "../" had been specified (so that we don't copy files to the parent
1701 dir of the destination).
1703 - If --delete is combined with a file-listing rsync command (i.e. no
1704 transfer is happening), avoid outputting a warning that we couldn't
1707 - If --stats is specified with --delete-after, ensure that all the
1708 "deleting" messages are output before the statistics.
1710 - Improved one "if" in the deletion code that was only checking errno
1711 for ENOTEMPTY when it should have also been checking for EEXIST (for
1712 compatibility with OS variations).
1716 - Added the --only-write-batch=FILE option that may be used (instead
1717 of --write-batch=FILE) to create a batch file without doing any
1718 actual updating of the destination. This allows you to divert all
1719 the file-updating data away from a slow data link (as long as you
1720 are pushing the data to the remote server when creating the batch).
1722 - When the generator is taking a long time to fill up its output buffer
1723 (e.g. if the transferred files are few, small, or missing), it now
1724 periodically flushes the output buffer so that the sender/receiver
1725 can get started on the files sooner rather than later.
1727 - Improved the keep-alive code to handle a long silence between the
1728 sender and the receiver that can occur when the sender is receiving
1729 the checksum data for a large file.
1731 - Improved the auth-errors that are logged by the daemon to include
1732 some information on why the authorization failed: wrong user,
1733 password mismatch, etc. (The client-visible message is unchanged!)
1735 - Improved the client's handling of an "@ERROR" from a daemon so that
1736 it does not complain about an unexpectedly closed socket (since we
1737 really did expect the socket to close).
1739 - If the daemon can't open the log-file specified in rsyncd.conf, fall
1740 back to using syslog and log an appropriate warning. This is better
1741 than what was typically a totally silent (and fatal) failure (since a
1742 daemon is not usually run with the --no-detach option that was
1743 necessary to see the error on stderr).
1745 - The man pages now consistently refer to an rsync daemon as a "daemon"
1746 instead of a "server" (to distinguish it from the server process in a
1747 non-daemon transfer).
1749 - Made a small change to the rrsync script (restricted rsync -- in the
1750 support dir) to make a read-only server reject all --remove-* options
1751 when sending files (to future-proof it against the possibility of
1752 other similar options being added at some point).
1756 - Rsync now calls setlocale(LC_CTYPE, ""). This enables isprint() to
1757 better discern which filename characters need to be escaped in
1758 messages (which should result in fewer escaped characters in some
1761 - Improved the naming of the log-file open/reopen/close functions.
1763 - Removed some protocol-compatibility code that was only needed to help
1764 someone running a pre-release of 2.6.4.
1768 - Added configure option "--disable-locale" to disable any use of
1769 setlocale() in the binary.
1771 - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
1772 rsync from being built without symlink or hard-link support.
1774 - Only #define HAVE_REMSH if it is going to be set to 1.
1776 - Configure now disables the use of mkstemp() under HP-UX (since they
1777 refuse to fix its broken handling of large files).
1779 - Configure now explicitly checks for the lseek64() function so that
1780 the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
1781 presence based on the presence of the off64_t type.
1783 - Configure no longer mentions the change in the default remote-shell
1784 (from rsh to ssh) that occurred for the 2.6.0 release.
1786 - Some minor enhancements to the test scripts.
1788 - Added a few new *.diff files to the patches dir, including a patch
1789 that enables the optional copying of extended attributes.
1792 NEWS for rsync 2.6.4 (30 March 2005)
1793 Protocol: 29 (changed)
1794 Changes since 2.6.3:
1798 - When rsync deletes a directory and outputs a verbose message about
1799 it, it now appends a trailing slash to the name instead of (only
1800 sometimes) outputting a preceding "directory " string.
1802 - The --stats output will contain file-list time-statistics if both
1803 sides are 2.6.4, or if the local side is 2.6.4 and the files are
1804 being pushed (since the stats come from the sending side).
1805 (Requires protocol 29 for a pull.)
1807 - The "%o" (operation) log-format escape now has a third value (besides
1808 "send" and "recv"): "del." (with trailing dot to make it 4 chars).
1809 This changes the way deletions are logged in the daemon's log file.
1811 - When the --log-format option is combined with --verbose, rsync now
1812 avoids outputting the name of the file twice in most circumstances.
1813 As long as the --log-format item does not refer to any post-transfer
1814 items (such as %b or %c), the --log-format message is output prior to
1815 the transfer, so --verbose is now the equivalent of a --log-format of
1816 '%n%L' (which outputs the name and any link info). If the log output
1817 must occur after the transfer to be complete, the only time the name
1818 is also output prior to the transfer is when --progress was specified
1819 (so that the name will precede the progress stats, and the full
1820 --log-format output will come after).
1822 - Non-printable characters in filenames are replaced with a '?' to
1823 avoid corrupting the screen or generating empty lines in the output.
1827 - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
1828 was only treating it as a special token in an rsync include/exclude
1831 - The combination of --verbose and --dry-run now mentions the full list
1832 of changes that would be output without --dry-run.
1834 - Avoid a mkdir warning when removing a directory in the destination
1835 that already exists in the --backup-dir.
1837 - An OS that has a binary mode for its files (such as cygwin) needed
1838 setmode(fd, O_BINARY) called on the temp-file we opened with
1839 mkstemp(). (Fix derived from cygwin's 2.6.3 rsync package.)
1841 - Fixed a potential hang when verbosity is high, the client side is
1842 the sender, and the file-list is large.
1844 - Fixed a potential protocol-corrupting bug where the generator could
1845 merge a message from the receiver into the middle of a multiplexed
1846 packet of data if only part of that data had been written out to the
1847 socket when the message from the generator arrived.
1849 - We now check if the OS doesn't support using mknod() for creating
1850 FIFOs and sockets, and compile-in some compatibility code using
1851 mkfifo() and socket() when necessary.
1853 - Fixed an off-by-one error in the handling of --max-delete=N. Also,
1854 if the --max-delete limit is exceeded during a run, we now output a
1855 warning about this at the end of the run and exit with a new error
1858 - One place in the code wasn't checking if fork() failed.
1860 - The "ignore nonreadable" daemon parameter used to erroneously affect
1861 readable symlinks that pointed to a non-existent file.
1863 - If the OS does not have lchown() and a chown() of a symlink will
1864 affect the referent of a symlink (as it should), we no longer try
1865 to set the user and group of a symlink.
1867 - The generator now properly runs the hard-link loop and the dir-time
1868 rewriting loop after we're sure that the redo phase is complete.
1870 - When --backup was specified with --partial-dir=DIR, where DIR is a
1871 relative path, the backup code was erroneously trying to backup a
1872 file that was put into the partial-dir.
1874 - If a file gets resent in a single transfer and the --backup option is
1875 enabled along with --inplace, rsync no longer performs a duplicate
1876 backup (it used to overwrite the first backup with the failed file).
1878 - One call to flush_write_file() was not being checked for an error.
1880 - The --no-relative option was not being sent from the client to a
1883 - If an rsync daemon specified "dont compress = ..." for a file and the
1884 client tried to specify --compress, the libz code was not handling a
1885 compression level of 0 properly. This could cause a transfer failure
1886 if the block-size for a file was large enough (e.g. rsync might have
1887 exited with an error for large files).
1889 - Fixed a bug that would sometimes surface when using --compress and
1890 sending a file with a block-size larger than 64K (either manually
1891 specified, or computed due to the file being really large). Prior
1892 versions of rsync would sometimes fail to decompress the data
1893 properly, and thus the transferred file would fail its verification.
1895 - If a daemon can't open the specified log file (i.e. syslog is not
1896 being used), die without crashing. We also output an error about
1897 the failure on stderr (which will only be seen if --no-detach was
1898 specified) and exit with a new error code (6).
1900 - A local transfer no longer duplicates all its include/exclude options
1901 (since the forked process already has a copy of the exclude list,
1902 there's no need to send them a set of duplicates).
1904 - The output of the items that are being updated by the generator (dirs,
1905 symlinks, devices) is now intermingled in the proper order with the
1906 output from the items that the receiver is updating (regular files)
1907 when pulling. This misordering was particularly bad when --progress
1908 was specified. (Requires protocol 29.)
1910 - When --timeout is specified, lulls that occur in the transfer while
1911 the generator is doing work that does not generate socket traffic
1912 (looking for changed files, deleting files, doing directory-time
1913 touch-ups, etc.) will cause a new keep-alive packet to be sent that
1914 should keep the transfer going as long as the generator continues to
1915 make progress. (Requires protocol 29.)
1917 - The stat size of a device is not added to the total file size of the
1918 items in the transfer (the size might be undefined on some OSes).
1920 - Fixed a problem with refused-option messages sometimes not making it
1921 back to the client side when a remote --files-from was in effect and
1922 the daemon was the receiver.
1924 - The --compare-dest option was not updating a file that differed in
1925 (the preserved) attributes from the version in the compare-dest DIR.
1927 - When rsync is copying files into a write-protected directory, fixed
1928 the change-report output for the directory so that we don't report
1929 an identical directory as changed.
1933 - Rsync now supports popt's option aliases, which means that you can
1934 use /etc/popt and/or ~/.popt to create your own option aliases.
1936 - Added the --delete-during (--del) option which will delete files
1937 from the receiving side incrementally as each directory in the
1938 transfer is being processed. This makes it more efficient than the
1939 default, before-the-transfer behavior, which is now also available as
1940 --delete-before (and is still the default --delete-WHEN option that
1941 will be chosen if --delete or --delete-excluded is specified without
1942 a --delete-WHEN choice). All the --del* options infer --delete, so
1943 an rsync daemon that refuses "delete" will still refuse to allow any
1944 file-deleting options (including the new --remove-sent-files option).
1946 - All the --delete-WHEN options are now more memory efficient:
1947 Previously an duplicate set of file-list objects was created on the
1948 receiving side for the entire destination hierarchy. The new
1949 algorithm only creates one directory of objects at a time (for files
1950 inside the transfer).
1952 - Added the --copy-dest option, which works like --link-dest except
1953 that it locally copies identical files instead of hard-linking them.
1955 - Added support for specifying multiple --compare-dest, --copy-dest, or
1956 --link-dest options, but only of a single type. (Promoted from the
1957 patches dir and enhanced.) (Requires protocol 29.)
1959 - Added the --max-size option. (Promoted from the patches dir.)
1961 - The daemon-mode options are now separated from the normal rsync
1962 options so that they can't be mixed together. This makes it
1963 impossible to start a daemon that has improper default option values
1964 (which could cause problems when a client connects, such as hanging
1967 - The --bwlimit option may now be used in combination with --daemon
1968 to specify both a default value for the daemon side and a value
1969 that cannot be exceeded by a user-specified --bwlimit option.
1971 - Added the "port" parameter to the rsyncd.conf file. (Promoted from
1972 the patches dir.) Also added "address". The command-line options
1973 take precedence over a config-file option, as expected.
1975 - In _exit_cleanup(): when we are exiting with a partially-received
1976 file, we now flush any data in the write-cache before closing the
1979 - The --inplace support was enhanced to work with --compare-dest,
1980 --link-dest, and (the new) --copy-dest options. (Requires protocol
1983 - Added the --dirs (-d) option for an easier way to copy directories
1984 without recursion. Any directories that are encountered are created
1985 on the destination. Specifying a directory with a trailing slash
1986 copies its immediate contents to the destination.
1988 - The --files-from option now implies --dirs (-d).
1990 - Added the --list-only option, which is mainly a way for the client to
1991 put the server into listing mode without needing to resort to any
1992 internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
1993 for a non-recursive listing). This option is used automatically
1994 (behind the scenes) when a modern rsync speaks to a modern daemon,
1995 but may also be specified manually if you want to force the use of
1996 the --list-only option over a remote-shell connection.
1998 - Added the --omit-dir-times (-O) option, which will avoid updating
1999 the modified time for directories when --times was specified. This
2000 option will avoid an extra pass through the file-list at the end of
2001 the transfer (to tweak all the directory times), which may provide
2002 an appreciable speedup for a really large transfer. (Promoted from
2005 - Added the --filter (-f) option and its helper option, -F. Filter
2006 rules are an extension to the existing include/exclude handling
2007 that also supports nested filter files as well as per-directory
2008 filter files (like .cvsignore, but with full filter-rule parsing).
2009 This new option was chosen in order to ensure that all existing
2010 include/exclude processing remained 100% compatible with older
2011 versions. Protocol 29 is needed for full filter-rule support, but
2012 backward-compatible rules work with earlier protocol versions.
2013 (Promoted from the patches dir and enhanced.)
2015 - Added the --delay-updates option that puts all updated files into
2016 a temporary directory (by default ".~tmp~", but settable via the
2017 --partial-dir=DIR option) until the end of the transfer. This
2018 makes the updates a little more atomic for a large transfer.
2020 - If rsync is put into the background, any output from --progress is
2023 - Documented the "max verbosity" setting for rsyncd.conf. (This
2024 setting was added a couple releases ago, but left undocumented.)
2026 - The sender and the generator now double-check the file-list index
2027 they are given, and refuse to try to do a file transfer on a
2028 non-file index (since that would indicate that something had gone
2031 - Added the --itemize-changes (-i) option, which is a way to output a
2032 more detailed list of what files changed and in what way. The effect
2033 is the same as specifying a --log-format of "%i %n%L" (see both the
2034 rsync and rsyncd.conf manpages). Works with --dry-run too.
2036 - Added the --fuzzy (-y) option, which attempts to find a basis file
2037 for a file that is being created from scratch. The current algorithm
2038 only looks in the destination directory for the created file, but it
2039 does attempt to find a match based on size/mod-time (in case the file
2040 was renamed with no other changes) as well as based on a fuzzy
2041 name-matching algorithm. This option requires protocol 29 because it
2042 needs the new file-sorting order. (Promoted from patches dir and
2043 enhanced.) (Requires protocol 29.)
2045 - Added the --remove-sent-files option, which lets you move files
2048 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
2049 enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
2050 literals in the rsync://HOST:PORT/PATH format.)
2052 - When rsync recurses to build the file list, it no longer keeps open
2053 one or more directory handles from the dir's parent dirs.
2055 - When building under windows, the default for --daemon is now to
2056 avoid detaching, requiring the new --detach option to force rsync
2059 - The --dry-run option can now be combined with either --write-batch or
2060 --read-batch, allowing you to run a do-nothing test command to see
2061 what would happen without --dry-run.
2063 - The daemon's "read only" config item now sets an internal read_only
2064 variable that makes extra sure that no write/delete calls on the
2065 read-only side can succeed.
2067 - The log-format % escapes can now have a numeric field width in
2068 between the % and the escape letter (e.g. "%-40n %08p").
2070 - Improved the option descriptions in the --help text.
2074 - Added atomic-rsync to the support dir: a perl script that will
2075 transfer some files using rsync, and then move the updated files into
2076 place all at once at the end of the transfer. Only works when
2077 pulling, and uses --link-dest and a parallel hierarchy of files to
2080 - Added mnt-excl to the support dir: a perl script that takes the
2081 /proc/mounts file and translates it into a set of excludes that will
2082 exclude all mount points (even mapped mounts to the same disk). The
2083 excludes are made relative to the specified source dir and properly
2086 - Added savetransfer.c to the support dir: a C program that can make
2087 a copy of all the data that flows over the wire. This lets you test
2088 for data corruption (by saving the data on both the sending side and
2089 the receiving side) and provides one way to debug a protocol error.
2091 - Added rrsync to the support dir: this is an updated version of Joe
2092 Smith's restricted rsync perl script. This helps to ensure that only
2093 certain rsync commands can be run by an ssh invocation.
2097 - Added better checking of the checksum-header values that come over
2100 - Merged a variety of file-deleting functions into a single function so
2101 that it is easier to maintain.
2103 - Improved the type of some variables (particularly blocksize vars) for
2104 consistency and proper size.
2106 - Got rid of the uint64 type (which we didn't need).
2108 - Use a slightly more compatible set of core #include directives.
2110 - Defined int32 in a way that ensures that the build dies if we can't
2111 find a variable with at least 32 bits.
2113 PROTOCOL DIFFERENCES FOR VERSION 29:
2115 - A 16-bit flag-word is transmitted after every file-list index. This
2116 indicates what is changing between the sender and the receiver. The
2117 generator now transmits an index and a flag-word to indicate when
2118 dirs and symlinks have changed (instead of producing a message),
2119 which makes the outputting of the information more consistent and
2120 less prone to screen corruption (because the local receiver/sender is
2121 now outputting all the file-change info messages).
2123 - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
2124 in the flag-word and the name of the file that was linked immediately
2125 follows in vstring format (see below).
2127 - If a file is being transferred with an alternate-basis file, the
2128 ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
2129 byte follows, indicating what type of basis file was chosen. If that
2130 indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
2131 is set in the flag-word and the name of the match in vstring format
2132 follows the basis byte. A vstring is a variable length string that
2133 has its size written prior to the string, and no terminating null.
2134 If the string is from 1-127 bytes, the length is a single byte. If
2135 it is from 128-32767 bytes, the length is written as ((len >> 8) |
2136 0x80) followed by (len % 0x100).
2138 - The sending of exclude names is done using filter-rule syntax. This
2139 means that all names have a prefixed rule indicator, even excludes
2140 (which used to be sent as a bare pattern, when possible). The -C
2141 option will include the per-dir .cvsignore merge file in the list of
2142 filter rules so it is positioned correctly (unlike in some older
2143 transfer scenarios).
2145 - Rsync sorts the filename list in a different way: it sorts the subdir
2146 names after the non-subdir names for each dir's contents, and it
2147 always puts a dir's contents immediately after the dir's name in the
2148 list. (Previously an item named "foo.txt" would sort in between
2149 directory "foo/" and "foo/bar".)
2151 - When talking to a protocol 29 rsync daemon, a list-only request
2152 is able to note this before the options are sent over the wire and
2153 the new --list-only option is included in the options.
2155 - When the --stats bytes are sent over the wire (or stored in a batch),
2156 they now include two elapsed-time values: one for how long it took to
2157 build the file-list, and one for how long it took to send it over the
2158 wire (each expressed in thousandths of a second).
2160 - When --delete-excluded is specified with some filter rules (AKA
2161 excludes), a client sender will now initiate a send of the rules to
2162 the receiver (older protocols used to omit the sending of excludes in
2163 this situation since there were no receiver-specific rules that
2164 survived --delete-excluded back then). Note that, as with all the
2165 filter-list sending, only items that are significant to the other
2166 side will actually be sent over the wire, so the filter-rule list
2167 that is sent in this scenario is often empty.
2169 - An index equal to the file-list count is sent as a keep-alive packet
2170 from the generator to the sender, which then forwards it on to the
2171 receiver. This normally invalid index is only a valid keep-alive
2172 packet if the 16-bit flag-word that follows it contains a single bit
2173 (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
2175 - A protocol-29 batch file includes a bit for the setting of the --dirs
2176 option and for the setting of the --compress option. Also, the shell
2177 script created by --write-batch will use the --filter option instead
2178 of --exclude-from to capture any filter rules.
2182 - Handle an operating system that use mkdev() in place of makedev().
2184 - Improved configure to better handle cross-compiling.
2187 NEWS for rsync 2.6.3 (30 Sep 2004)
2188 Protocol: 28 (unchanged)
2189 Changes since 2.6.2:
2193 - A bug in the sanitize_path routine (which affects a non-chrooted
2194 rsync daemon) could allow a user to craft a pathname that would get
2195 transformed into an absolute path for certain options (but not for
2196 file-transfer names). If you're running an rsync daemon with chroot
2197 disabled, *please upgrade*, ESPECIALLY if the user privs you run
2198 rsync under is anything above "nobody".
2200 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
2202 - Please note that the 2-line footer (output when verbose) now uses the
2203 term "sent" instead of "wrote" and "received" instead of "read". If
2204 you are not parsing the numeric values out of this footer, a script
2205 would be better off using the empty line prior to the footer as the
2206 indicator that the verbose output is over.
2208 - The output from the --stats option was similarly affected to change
2209 "written" to "sent" and "read" to "received".
2211 - Rsync ensures that a filename that contains a newline gets mentioned
2212 with each newline transformed into a question mark (which prevents a
2213 filename from causing an empty line to be output).
2215 - The "backed up ..." message that is output when at least 2 --verbose
2216 options are specified is now the same both with and without the
2217 --backup-dir option.
2221 - Fixed a crash bug that might appear when --delete was used and
2222 multiple source directories were specified.
2224 - Fixed a 32-bit truncation of the file length when generating the
2227 - The --backup code no longer attempts to create some directories
2228 over and over again (generating warnings along the way).
2230 - Fixed a bug in the reading of the secrets file (by the daemon) and
2231 the password file (by the client): the files no longer need to be
2232 terminated by a newline for their content to be read in.
2234 - If a file has a read error on the sending side or the reconstructed
2235 data doesn't match the expected checksum (perhaps due to the basis
2236 file changing during the transfer), the receiver will no longer
2237 retain the resulting file unless the --partial option was specified.
2238 (Note: for the read-error detection to work, neither side can be
2239 older than 2.6.3 -- older receivers will always retain the file, and
2240 older senders don't tell the receiver that the file had a read
2243 - If a file gets resent in a single transfer and the --backup option
2244 is enabled, rsync no longer performs a duplicate backup (it used to
2245 overwrite the original file in the backup area).
2247 - Files specified in the daemon's "exclude" or "exclude from" config
2248 items are now excluded from being uploaded (assuming that the module
2249 allows uploading at all) in addition to the old download exclusion.
2251 - Got rid of a potential hang in the receiver when near the end of a
2254 - When using --backup without a --backup-dir, rsync no longer preserves
2255 the modify time on directories. This avoids confusing NFS.
2257 - When --copy-links (-L) is specified, we now output a separate error
2258 for a symlink that has no referent instead of claiming that a file
2261 - The --copy-links (-L) option no longer has the side-effect of telling
2262 the receiving side to follow symlinks. See the --keep-dirlinks
2263 option (mentioned below) for a way to specify that behavior.
2265 - Error messages from the daemon server's option-parsing (such as
2266 refused options) are now successfully transferred back to the client
2267 (the server used to fail to send the message because the socket
2268 wasn't in the right state for the message to get through).
2270 - Most transfer errors that occur during a daemon transfer are now
2271 returned to the user in addition to being logged (some messages are
2272 intended to be daemon-only and are not affected by this).
2274 - Fixed a bug in the daemon authentication code when using one of the
2275 batch-processing options.
2277 - We try to work around some buggy IPv6 implementations that fail to
2278 implement IPV6_V6ONLY. This should fix the "address in use" error
2279 that some daemons get when running on an OS with a buggy IPv6
2280 implementation. Also, if the new code gets this error, we might
2281 suggest that the user specify --ipv4 or --ipv6 (if we think it will
2284 - When the remote rsync dies, make a better effort to recover any error
2285 messages it may have sent before dying (the local rsync used to just
2286 die with a socket-write error).
2288 - When using --delete and a --backup-dir that contains files that are
2289 hard-linked to their destination equivalents, rsync now makes sure
2290 that removed files really get removed (avoids a really weird rename()
2293 - Avoid a bogus run-time complaint about a lack of 64-bit integers when
2294 the int64 type is defined as an off_t and it actually has 64-bits.
2296 - Added a configure check for open64() without mkstemp64() so that we
2297 can avoid using mkstemp() when such a combination is encountered.
2298 This bypasses a problem writing out large temp files on OSes such as
2301 - Fixed an age-old crash problem with --read-batch on a local copy
2302 (rsync was improperly assuming --whole-file for the local copy).
2304 - When --dry-run (-n) is used and the destination directory does not
2305 exist, rsync now produces a correct report of files that would be
2306 sent instead of dying with a chdir() error.
2308 - Fixed a bug that could cause a slow-to-connect rsync daemon to die
2309 with an error instead of waiting for the connection to finish.
2311 - Fixed an ssh interaction that could cause output to be lost when the
2312 user chose to combine the output of rsync's stdout and stderr (e.g.
2315 - Fixed an option-parsing bug when --files-from got passed to a daemon.
2319 - Added the --partial-dir=DIR option that lets you specify where to
2320 (temporarily) put a partially transferred file (instead of over-
2321 writing the destination file). E.g. --partial-dir=.rsync-partial
2322 Also added support for the RSYNC_PARTIAL_DIR environment variable
2323 that, when found, transforms a regular --partial option (such as
2324 the convenient -P option) into one that also specifies a directory.
2326 - Added --keep-dirlinks (-K), which allows you to symlink a directory
2327 onto another partition on the receiving side and have rsync treat it
2328 as matching a normal directory from the sender.
2330 - Added the --inplace option that tells rsync to write each destination
2331 file without using a temporary file. The matching of existing data
2332 in the destination file can be severely limited by this, but there
2333 are also cases where this is more efficient (such as appending data).
2334 Use only when needed (see the man page for more details).
2336 - Added the "write only" option for the daemon's config file.
2338 - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
2339 and documented all these options in the man page.
2341 - Improved the handling of the --bwlimit option so that it's less
2342 bursty, more accurate, and works properly over a larger range of
2345 - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
2346 SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
2348 - Added the --checksum-seed=N option for advanced users.
2350 - Batch writing/reading has a brand-new implementation that is simpler,
2351 fixes a few weird problems with the old code (such as no longer
2352 sprinkling the batch files into different dirs or even onto different
2353 systems), and is much less intrusive into the code (making it easier
2354 to maintain for the future). The new code generates just one data
2355 file instead of three, which makes it possible to read the batch on
2356 stdin via a remote shell. Also, the old requirement of forcing the
2357 same fixed checksum-seed for all batch processing has been removed.
2359 - If an rsync daemon has a module set with "list = no" (which hides its
2360 presence in the list of available modules), a user that fails to
2361 authenticate gets the same "unknown module" error that they would get
2362 if the module were actually unknown (while still logging the real
2363 error to the daemon's log file). This prevents fishing for module
2366 - The daemon's "refuse options" config item now allows you to match
2367 option names using wildcards and/or the single-letter option names.
2369 - Each transferred file now gets its permissions and modified-time
2370 updated before the temp-file gets moved into place. Previously, the
2371 finished file would have a very brief window where its permissions
2372 disallowed all group and world access.
2374 - Added the ability to parse a literal IPv6 address in an "rsync:" URL
2375 (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
2377 - The daemon's wildcard expanding code can now handle more than 1000
2378 filenames (it's now limited by memory instead of having a hard-wired
2383 - Some cleanup in the exclude code has saved some per-exclude memory
2384 and made the code easier to maintain.
2386 - Improved the argv-overflow checking for a remote command that has a
2389 - Use rsyserr() in the various places that were still calling rprintf()
2390 with strerror() as an arg.
2392 - If an rsync daemon is listening on multiple sockets (to handle both
2393 IPv4 and IPv6 to a single port), we now close all the unneeded file
2394 handles after we accept a connection (we used to close just one of
2397 - Optimized the handling of larger block sizes (rsync used to slow to a
2398 crawl if the block size got too large).
2400 - Optimized away a loop in hash_search().
2402 - Some improvements to the sanitize_path() and clean_fname() functions
2403 makes them more efficient and produce better results (while still
2404 being compatible with the file-name cleaning that gets done on both
2405 sides when sending the file-list).
2407 - Got rid of alloc_sanitize_path() after adding a destination-buffer
2408 arg to sanitize_path() made it possible to put all the former's
2409 functionality into the latter.
2411 - The file-list that is output when at least 4 verbose options are
2412 specified reports the uid value on the sender even when rsync is
2413 not running as root (since we might be sending to a root receiver).
2417 - Added a "gen" target to rebuild most of the generated files,
2418 including configure, config.h.in, the man pages, and proto.h.
2420 - If "make proto" doesn't find some changes in the prototypes, the
2421 proto.h file is left untouched (its time-stamp used to always be
2424 - The variable $STRIP (that is optionally set by the install-strip
2425 target's rule) was changed to $INSTALL_STRIP because some systems
2426 have $STRIP already set in the environment.
2428 - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
2430 - When cross-compiling, the gettimeofday() function is now assumed to
2431 be a modern version that takes two-args (since we can't test it).
2435 - The scripts in the testsuite dir were cleaned up a bit and a few
2438 - Some new diffs were added to the patches dir, and some accepted
2442 NEWS for rsync 2.6.2 (30 Apr 2004)
2443 Protocol: 28 (unchanged)
2444 Changes since 2.6.1:
2448 - Fixed a major bug in the sorting of the filenames when --relative
2449 is used for some sources (just sources such as "/" and "/*" were
2450 affected). This fix ensures that we ask for the right file-list
2451 item when requesting changes from the sender.
2453 - Rsync now checks the return value of the close() function to
2454 better report disk-full problems on an NFS file system.
2456 - Restored the old daemon-server behavior of logging error messages
2457 rather than returning them to the user. (A better long-term fix
2458 will be sought in the future.)
2460 - An obscure uninitialized-variable bug was fixed in the uid/gid
2461 code. (This bug probably had no ill effects.)
2465 - Got rid of the configure check for sys/sysctl.h (it wasn't used
2466 and was causing a problem on some systems). Also improved the
2467 broken-largefile-locking test to try to avoid failure due to an
2470 - Fixed a compile problem on systems that don't define
2473 - Fixed a compile problem in the popt source for compilers that
2474 don't support __attribute__.
2478 - Improved the testsuite's "merge" test to work on OSF1.
2480 - Two new diffs were added to the patches dir.
2483 NEWS for rsync 2.6.1 (26 Apr 2004)
2484 Protocol: 28 (changed)
2485 Changes since 2.6.0:
2489 - Paths sent to an rsync daemon are more thoroughly sanitized when
2490 chroot is not used. If you're running a non-read-only rsync
2491 daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
2492 user privs you run rsync under is anything above "nobody".
2496 - Lower memory use, more optimal transfer of data over the socket,
2497 and lower CPU usage (see the INTERNAL section for details).
2499 - The RSYNC_PROXY environment variable can now contain a
2500 "USER:PASS@" prefix before the "HOST:PORT" information.
2503 - The --progress output now mentions how far along in the transfer
2504 we are, including both a count of files transferred and a
2505 percentage of the total file-count that we've processed. It also
2506 shows better current-rate-of-transfer and remaining-transfer-time
2509 - Documentation changes now attempt to describe some often mis-
2510 understood features more clearly.
2514 - When -x (--one-file-system) is combined with -L (--copy-links) or
2515 --copy-unsafe-links, no symlinked files are skipped, even if the
2516 referent file is on a different filesystem.
2518 - The --link-dest code now works properly for a non-root user when
2519 (1) the UIDs of the source and destination differ and -o was
2520 specified, or (2) when the group of the source can't be used on
2521 the destination and -g was specified.
2523 - Fixed a bug in the handling of -H (hard-links) that might cause
2524 the expanded PATH/NAME value of the current item to get
2525 overwritten (due to an expanded-name caching bug).
2527 - We now reset the "new data has been sent" flag at the start of
2528 each file we send. This makes sure that an interrupted transfer
2529 with the --partial option set doesn't keep a shorter temp file
2530 than the current basis file when no new data has been transferred
2531 over the wire for that file.
2533 - Fixed a byte-order problem in --batch-mode on big-endian machines.
2536 - When using --cvs-exclude, the exclude items we get from a
2537 per-directory's .cvsignore file once again only affect that one
2538 directory (not all following directories too). The items are also
2539 now properly word-split and parsed without any +/- prefix parsing.
2541 - When specifying the USER@HOST: prefix for a file, the USER part
2542 can now contain an '@', if needed (i.e. the last '@' is used to
2543 find the HOST, not the first).
2545 - Fixed some bugs in the handling of group IDs for non-root users:
2546 (1) It properly handles a group that the sender didn't have a name
2547 for (it would previously skip changing the group on any files in
2548 that group). (2) If --numeric-ids is used, rsync no longer
2549 attempts to set groups that the user doesn't have the permission
2552 - Fixed the "refuse options" setting in the rsyncd.conf file.
2554 - Improved the -x (--one-file-system) flag's handling of any mount-
2555 point directories we encounter. It is both more optimal (in that
2556 it no longer does a useless scan of the contents of the mount-
2557 point dirs) and also fixes a bug where a remapped mount of the
2558 original filesystem could get discovered in a subdir we should be
2561 - Rsync no longer discards a double-slash at the start of a filename
2562 when trying to open the file. It also no longer constructs names
2563 that start with a double slash (unless the user supplied them).
2565 - Path-specifying options to a daemon should now work the same with
2566 or without chroot turned on. Previously, such a option (such as
2567 --link-dest) would get its absolute path munged into a relative
2568 one if chroot was not on, making that setting fairly useless.
2569 Rsync now transforms the path into one that is based on the
2570 module's base dir when chroot is not enabled.
2572 - Fixed a compatibility problem interacting with older rsync
2573 versions that might send us an empty --suffix value without
2574 telling us that --backup-dir was specified.
2576 - The "hosts allow" option for a daemon-over-remote-shell process
2577 now has improved support for IPv6 addresses and a fix for systems
2578 that have a length field in their socket structs.
2580 - Fixed the ability to request an empty backup --suffix when sending
2581 files to an rsync daemon.
2583 - Fixed an option-parsing bug when --files-from was sent to a server
2588 - Most of the I/O is now buffered, which results in a pretty large
2589 speedup when running under MS Windows. (Craig Barratt)
2591 - Optimizations to the name-handling/comparing code have made some
2592 significant reductions in user-CPU time for large file sets.
2594 - Some cleanup of the variable types make the code more consistent.
2596 - Reduced memory requirements of hard link preservation.
2599 - Implemented a new algorithm for hard-link handling that speeds up
2600 the code significantly. (J.W. Schultz and Wayne Davison)
2602 - The --hard-link option now uses the first existing file in the
2603 group of linked files as the basis for the transfer. This
2604 prevents the sub-optimal transfer of a file's data when a new
2605 hardlink is added on the sending side and it sorts alphabetically
2606 earlier in the list than the files that are already present on the
2609 - Dropped support for protocol versions less than 20 (2.3.0 released
2610 15 Mar 1999) and activated warnings for protocols less than 25
2611 (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
2614 - More optimal data transmission for --hard-links (protocol 28).
2616 - More optimal data transmission for --checksum (protocol 28).
2618 - Less memory is used when --checksum is specified.
2620 - Less memory is used in the file list (a per-file savings).
2622 - The generator is now better about not modifying the file list
2623 during the transfer in order to avoid a copy-on-write memory
2624 bifurcation (on systems where fork() uses shared memory).
2625 Previously, rsync's shared memory would slowly become unshared,
2626 resulting in real memory usage nearly doubling on the receiving
2627 side by the end of the transfer. Now, as long as permissions
2628 are being preserved, the shared memory should remain that way
2629 for the entire transfer.
2631 - Changed hardlink info and file_struct + strings to use allocation
2632 pools. This reduces memory use for large file-sets and permits
2633 freeing memory to the OS. (J.W. Schultz)
2635 - The 2 pipes used between the receiver and generator processes
2636 (which are forked on the same machine) were reduced to 1 pipe and
2637 the protocol improved so that (1) it is now impossible to have the
2638 "redo" pipe fill up and hang rsync, and (2) trailing messages from
2639 the receiver don't get lost on their way through the generator
2640 over to the sender (which mainly affected hard-link messages and
2641 verbose --stats output).
2643 - Improved the internal uid/gid code to be more portable and a
2644 little more optimized.
2646 - The device numbers sent when using --devices are now sent as
2647 separate major/minor values with 32-bit accuracy (protocol 28).
2648 Previously, the copied devices were sent as a single 32-bit
2649 number. This will make inter-operation of 64-bit binaries more
2650 compatible with their 32-bit brethren (with both ends of the
2651 connection are using protocol 28). Note that optimizations in the
2652 binary protocol for sending the device numbers often results in
2653 fewer bytes being used than before, even though more precision is
2656 - Some cleanup of the exclude/include structures and its code made
2657 things clearer (internally), simpler, and more efficient.
2659 - The reading & writing of the file-list in batch-mode is now
2660 handled by the same code that sends & receives the list over the
2661 wire. This makes it much easier to maintain. (Note that the
2662 batch code is still considered to be experimental.)
2666 - The configure script now accepts --with-rsyncd-conf=PATH to
2667 override the default value of the /etc/rsyncd.conf file.
2669 - Fixed configure bug when running "./configure --disable-ipv6".
2671 - Fixed compilation problem on Tru64 Unix (having to do with
2672 sockaddr.sa_len and sockaddr.sin_len).
2676 - Fixed "make test" bug when build dir is not the source dir.
2678 - Added a couple extra diffs in the "patches" dir, removed the ones
2679 that got applied, and rebuilt the rest.
2682 NEWS for rsync 2.6.0 (1 Jan 2004)
2683 Protocol: 27 (changed)
2684 Changes since 2.5.7:
2688 * "ssh" is now the default remote shell for rsync. If you want to
2689 change this, configure like this: "./configure --with-rsh=rsh".
2691 * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
2692 Note that --from0 affects the line-ending character for all the
2693 files read by the --*-from options. (Wayne Davison)
2695 * Length of csum2 is now per-file starting with protocol version
2698 * Per-file dynamic block size is now sqrt(file length). The
2699 per-file checksum size is determined according to an algorithm
2700 provided by Donovan Baarda which reduces the probability of rsync
2701 algorithm corrupting data and falling back using the whole md4
2702 checksums. (J.W. Schultz, Donovan Baarda)
2704 * The --stats option no longer includes the (debug) malloc summary
2705 unless the verbose option was specified at least twice.
2707 * Added a new error/warning code for when files vanish from the
2708 sending side. Made vanished source files not interfere with the
2709 file-deletion pass when --delete-after was specified.
2711 * Various trailing-info sections are now preceded by a newline.
2715 * Fixed several exclude/include matching bugs when using wild-cards.
2716 This has a several user-visible effects, all of which make the
2717 matching more consistent and intuitive. This should hopefully not
2718 cause anyone problems since it makes the matching work more like
2719 what people are expecting. (Wayne Davison)
2721 - A pattern with a "**" no longer causes a "*" to match slashes.
2722 For example, with "/*/foo/**", "foo" must be 2 levels deep.
2723 [If your string has BOTH "*" and "**" wildcards, changing the
2724 "*" wildcards to "**" will provide the old behavior in all
2727 - "**/foo" now matches at the base of the transfer (like /foo
2728 does). [Use "/**/foo" to get the old behavior in all versions.]
2730 - A non-anchored wildcard term floats to match beyond the base of
2731 the transfer. E.g. "CVS/R*" matches at the end of the path,
2732 just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
2733 to get the old behavior in all versions.]
2735 - Including a "**" in the match term causes it to be matched
2736 against the entire path, not just the name portion, even if
2737 there aren't any interior slashes in the term. E.g. "foo**bar"
2738 would exclude "/path/foo-bar" (just like before) as well as
2739 "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
2740 old behavior in all versions.]
2742 * The exclude list specified in the daemon's config file is now
2743 properly applied to the pulled items no matter how deep the
2744 user's file-args are in the source tree. (Wayne Davison)
2746 * For protocol version >= 27, mdfour_tail() is called when the
2747 block size (including checksum_seed) is a multiple of 64.
2748 Previously it was not called, giving the wrong MD4 checksum.
2751 * For protocol version >= 27, a 64 bit bit counter is used in
2752 mdfour.c as required by the RFC. Previously only a 32 bit bit
2753 counter was used, causing incorrect MD4 file checksums for
2754 file sizes >= 512MB - 4. (Craig Barratt)
2756 * Fixed a crash bug when interacting with older rsync versions and
2757 multiple files of the same name are destined for the same dir.
2760 * Keep tmp names from overflowing MAXPATHLEN.
2762 * Make --link-dest honor the absence of -p, -o, and -g.
2764 * Made rsync treat a trailing slash in the destination in a more
2767 * Fixed file I/O error detection. (John Van Essen)
2769 * Fixed bogus "malformed address {hostname}" message in rsyncd log
2770 when checking IP address against hostnames from "hosts allow"
2771 and "hosts deny" parameters in config file.
2773 * Print heap statistics when verbose >= 2 instead of when >= 1.
2775 * Fixed a compression (-z) bug when syncing a mostly-matching file
2776 that contains already-compressed data. (Yasuoka Masahiko and
2779 * Fixed a bug in the --backup code that could cause deleted files
2780 to not get backed up.
2782 * When the backup code makes new directories, create them with mode
2783 0700 instead of 0755 (since the directory permissions in the
2784 backup tree are not yet copied from the main tree).
2786 * Call setgroups() in a more portable manner.
2788 * Improved file-related error messages to better indicate exactly
2789 what pathname failed. (Wayne Davison)
2791 * Fixed some bugs in the handling of --delete and --exclude when
2792 using the --relative (-R) option. (Wayne Davison)
2794 * Fixed bug that prevented regular files from replacing
2795 special files and caused a directory in --link-dest or
2796 --compare-dest to block the creation of a file with the
2797 same path. A directory still cannot be replaced by a
2798 regular file unless --delete specified. (J.W. Schultz)
2800 * Detect and report when open or opendir succeed but read and
2801 readdir fail caused by network filesystem issues and truncated
2802 files. (David Norwood, Michael Brown, J.W. Schultz)
2804 * Added a fix that should give ssh time to restore the tty settings
2805 if the user presses Ctrl-C at an ssh password prompt.
2809 * Eliminated vestigial support for old versions that we stopped
2810 supporting. (J.W. Schultz)
2812 * Simplified some of the option-parsing code. (Wayne Davison)
2814 * Some cleanup made to the exclude code, as well as some new
2815 defines added to enhance readability. (Wayne Davison)
2817 * Changed the protocol-version code so that it can interact at a
2818 lower protocol level than the maximum supported by both sides.
2819 Added an undocumented option, --protocol=N, to force the value
2820 we advertise to the other side (primarily for testing purposes).

2848 as modules, over a secure protocol, such as ssh. (JD Paul)

2866 * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"

2870 terminations. (J.W. Schultz)

2877 * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
2878 L. Allen, Martin Pool)
2880 * Generate each file's rolling-checksum data as we send it, not
2881 in a separate (memory-eating) pass before hand. This prevents

2884 * Fix compilation on Tru64. (Albert Chin, Zoong Pham)

2893 dups in a row. (Wayne Davison)

2896 processes and sometimes return an exit code of 0 instead of showing
2897 an error. (David R. Staples, Dave Dykstra)
2899 * Fixed bug in --copy-unsafe-links that caused it to be completely

2942 a fatal signal rsync will try to open an xterm running gdb,
2943 similarly to Samba's "panic action" or GNOME's bug-buddy.

2970 Protocol: 26 (unchanged)
2971 Changes since 2.5.3:
2975 * Additional fix for zlib double-free bug. (Martin Pool, Andrew
2976 Tridgell) (CVE CAN-2002-0059)
2980 * Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus)
2981 (Note that rsync still uses a custom version of zlib; you can
2982 not just link against a system library. See zlib/README.rsync)

2988 Protocol: 26 (unchanged)
2989 Changes since 2.5.2:
2993 * Make sure that supplementary groups are removed from a server
2994 process after changing uid and gid. (Ethan Benson) (Debian bug
2995 #132272, CVE CAN-2002-0080)
2999 * Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE
3002 * Fixed problem that in many cases caused the error message
3003 unexpected read size of 0 in map_ptr
3004 and resulted in the wrong data being copied.
3006 * Fixed compilation errors on some systems caused by the use of
3007 "unsigned int64" in rsync.h.
3009 * Fixed problem on systems such as Sunos4 that do not support realloc
3010 on a NULL pointer; error was "out of memory in flist_expand".
3012 * Fix for rsync server processes hanging around after the client
3013 unexpectedly disconnects. (Colin Walters) (Debian bug #128632)
3015 * Cope with BSD systems on which mkdir() will not accept a trailing
3020 * Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that
3021 rsync still uses a custom version of zlib; you can not just link
3022 against a system library. See zlib/README.rsync)
3024 * Command to initiate connections is only shown with -vv, rather
3025 than -v as in 2.5.2. Output from plain -v is more similar to
3026 what was historically used so as not to break scripts that try
3027 to parse the output.
3029 * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
3031 * Made the --write-batch and --read-batch options actually work
3032 and added documentation in the man page (Jos Backus)
3034 * If the daemon is unable to fork a child to accept a connection,
3035 print an error message. (Colin Walters)
3038 NEWS for rsync 2.5.2 (26 Jan 2002)
3039 Protocol: 26 (changed)
3040 Changes since 2.5.1:
3044 * Signedness security patch from Sebastian Krahmer
3045 <krahmer@suse.de> -- in some cases we were not sufficiently
3046 careful about reading integers from the network.
3050 * Fix possible string mangling in log files.
3052 * Fix for setting local address of outgoing sockets.
3054 * Better handling of hardlinks and devices on platforms with
3055 64-bit dev_t or ino_t.
3057 * Name resolution on machines supporting IPv6 is improved.
3059 * Fix for device nodes. (dann frazier) (Debian #129135)
3063 * With -v, rsync now shows the command used to initiate an ssh/rsh
3066 * --statistics now shows memory heap usage on platforms that
3069 * "The Ted T'so school of program optimization": make progress
3070 visible and people will think it's faster. (With --progress,
3071 rsync will show you how many files it has seen as it builds the
3072 file_list, giving some indication that it has not hung.)
3074 * Improvements to batch mode support. This is still experimental
3075 but testing would be welcome. (Jos Backus)
3077 * New --ignore-existing option, patch previously distributed with
3078 Vipul's Razor. (Debian #124286)
3081 NEWS for rsync 2.5.1 (3 Jan 2002)
3082 Protocol: 25 (unchanged)

3090 * Correct string<->address parsing for both IPv4 and 6.
3091 (YOSHIFUJI Hideaki, SUMIKAWA Munechika and Jun-ichiro "itojun"
3094 * Various fixes for IPv6 support. (Dave Dykstra)
3096 * rsync.1 typo fix. (Matt Kraai)
3098 * Test suite typo fixes. (Tom Schmidt)
3100 * rsync.1 grammar and clarity improvements. (Edward
3103 * Correction to ./configure tests for inet_ntop. (Jeff Garzik)
3107 * --progress and -P now show estimated data transfer rate (in a
3108 multiple of bytes/s) and estimated time to completion. (Rik
3111 * --no-detach option, required to run as a W32 service and also
3112 useful when running on Unix under daemontools, AIX's SRC, or a
3113 debugger. (Max Bowsher, Jos Backus)
3115 * Clearer error messages for some conditions.
3118 NEWS for rsync 2.5.0 (30 Nov 2001)
3119 Protocol: 25 (changed)
3120 Changes since 2.4.6:
3124 * Martin Pool <mbp@samba.org> is now a co-maintainer.
3128 * Support for LSB-compliant packaging <http://www.linuxbase.org/>
3130 * Shell wildcards are allowed in "auth users" lines.
3132 * Merged UNC rsync+ patch to support creation of standalone patch
3133 sets. By Bert J. Dempsey and Debra Weiss, updated by Jos
3134 Backus. <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
3136 * IPv6 support based on a patch from KAME.net, on systems
3137 including modern versions of Linux, Solaris, and HP-UX. Also
3138 includes IPv6 compatibility functions for old OSs by the
3139 Internet Software Consortium, Paul Vixie, the OpenSSH
3140 portability project, and OpenBSD.
3144 * Include/exclude cluestick: with -vv, print out whether files are
3145 included or excluded and why.
3147 * Many error messages have more friendly explanations and more
3150 * Manual page improvements plus scanty protocol documentation.
3152 * When running as --daemon in the background and using a "log
3153 file" rsyncd.conf directive, close the log file every time it is
3154 open when going to sleep on the socket. This allows the log
3155 file to get cleaned out by another process.
3157 * Change to using libpopt rather than getopt for processing
3158 options. This makes the code cleaner and the behaviour more
3159 consistent across platforms. popt is included and built if not
3160 installed on the platform.
3162 * More details in --version, including note about whether 64-bit
3163 files, symlinks and hardlinks are supported.
3165 * MD4 code may use less CPU cycles.
3167 * Use mkstemp on systems where it is secure. If we use mktemp,
3168 explain that we do it in a secure way.
3170 * --whole-file is the default when source and target are on the
3175 * Fix for various bugs causing rsync to hang.
3177 * Attempt to fix Large File Summit support on AIX.
3179 * Attempt to fix error handling lockup bug.
3181 * Give a non-0 exit code if *any* of the files we have been asked
3182 to transfer fail to transfer.
3184 * For log messages containing ridiculously long strings that might
3185 overflow a buffer rsync no longer aborts, but rather prints an
3186 ellipsis at the end of the string. (Patch from Ed Santiago.)
3190 * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
3192 * autoconf2.52 (or later) is now required to rebuild the autoconf
3193 scripts. It is not required to simply build rsync.
