(Fix derived from the cygwin's rsync package.) + - Fixed an overzealous sanitizing bug in the handling of the --link-dest, + --copy-dest, and --compare-dest options to a daemon without chroot: if + the copy's destination dir is deeper than the top of the module's path, + these options now accept a safe number of parent-dir (../) references + (since these options are relative to the destination dir). The old code + incorrectly chopped off all "../" prefixes for these options, no matter + how deep the destination directory was in the module's hierarchy. - - Fixed a potential hang when verbosity is high, the client side is - the sender, and the file-list is large. + - Fixed a bug where a deferred info/error/log message could get sent + directly to the sender instead of being handled by rwrite() in the + generator. This fixes an "unexpected tag 3" fatal error, and should + also fix a potential problem where a deferred info/error message from + the receiver might bypass the log file and get sent only to the client + process. (These problems could only affect an rsync daemon that was + receiving files.) - - We now check if the OS doesn't support using mknod() for creating - FIFOs and sockets, and compile-in using mkfifo() and socket() when - necessary. + - Fixed a bug when --inplace was combined with a --*-dest option and we + update a file's data using an alternate basis file. The code now + notices that it needs to copy the matching data from the basis file + instead of (wrongly) assuming that it was already present in the file. - - Fixed an off-by-one error in the handling of --max-delete=N. + - Fixed a bug where using --dry-run with a --*-dest option with a path + relative to a directory that does not yet exist: the affected option + gets its proper path value so that the output of the dry-run is right. - - One place in the code wasn't checking if fork() failed. + - Fixed a bug in the %f logfile escape when receiving files: the + destination path is now included in the output (e.g. you can now tell + when a user specifies a subdir inside a module). - - The "ignore nonreadable" daemon parameter no longer affects symlinks - that are being copied, even if they point nowhere. + - If the receiving side fails to create a directory, it will now skip + trying to update everything that is inside that directory. - - If the OS does not have lchown() and its chown() tries to set the - referent of a symlink (as it should), we no longer try to set the - user and group of a symlink. + - If --link-dest is specified with --checksum but without --times, rsync + will now allow a hard-link to be created to a matching link-dest file + even when the file's modify-time doesn't match the server's file. - - The generator now properly runs the hard-link loop and the dir-time - rewriting loop after we're sure that the redo phase is complete. + - The daemon now calls more timezone-using functions prior to doing a + chroot. This should help some C libraries to generate proper timestamps + from inside a chrooted daemon (and to not try to access /etc/timezone + over and over again). - - When --backup was specified with --partial-dir=DIR (where DIR is a - relative path), the backup code was erroneously trying to backup a - file that was put into the partial-dir. + - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option: + it now deletes an alternate basis file from the partial-dir that was used + to successfully update a destination file. - - One call to flush_write_file() was not being checked for an error. + - Fixed a bug in the handling of --delete-excluded when using a per-dir + merge file: the merge file is now honored on the receiving side, and + only its unqualified include/exclude commands are ignored (just as is + done for global include/excludes). - - The --no-relative option was not being sent from the client to a - server sender. + - Fixed a recent bug where --delete was not working when transferring from + the root (/) of the filesystem with --relative enabled. - - If an rsync daemon specified "dont compress = ..." for a file and the - client tried to specify --compress, the libz code was not handling a - compression level of 0 properly. This could cause a transfer failure - if the block-size for a file was large enough (i.e. rsync might have - exited with an error for large files). + - Fixed a recent bug where an --exclude='*' could affect the root (/) of + the filesystem with --relative enabled. - - If a daemon can't open the specified log file (i.e. syslog is not - being used), die without crashing. We also try to output an error - about the failure (which will only be seen if --no-detach was - specified). + - When --inplace creates a file, it is now created with owner read/write + permissions (0600) instead of no permissions at all. This avoids a + problem continuing a transfer that was interrupted (since --inplace + will not update a file that has no write permissions). - - A local transfer no longer duplicates all its include/exclude options - by sending the forked process a copy of the list it already has. + - If either --remove-source-files or --remove-sent-files is enabled and we + are unable to remove the source file, rsync now outputs an error. - ENHANCEMENTS: + - Fixed a bug in the daemon's "incoming chmod" rule: newly-created + directories no longer get the 'F' (file) rules applied to them. - - Rsync now supports popt's option aliases, which means that you can - use /etc/popt and/or ~/.popt to create your own option aliases. - - - Added the --delete-during (--del) option which will delete files - from on the receiving side incrementally as each directory in the - transfer is being processed (which makes it more efficient than the - default, before-the-transfer behavior of --delete). Note that the - --del option is implemented as an internally-defined popt alias, so - an rsync daemon that refuses "delete" (which, for safety's sake, - really matches "delete*") will still refuse all delete options. The - default --delete behavior is also explicitly selectable via - --delete-before. - - - All the --delete-WHEN options are now more memory efficient: - Previously an entire duplicate set of file-list objects was created - on the receiving side for the entire destination hierarchy. The new - algorithm only creates one directory of objects at a time. - - - Added the --copy-dest option, which works like --link-dest except - that it includes copies of identical files. - - - Added support for specifying multiple --compare-dest, --copy-dest, or - --link-dest options, but only of a single type. (Promoted from the - patches dir and enhanced.) - - - Added the --max-size option. (Promoted from the patches dir.) - - - The daemon-mode options were separated from the normal rsync options - so that they can't be mixed together. This makes it impossible to - start a daemon that had improper default option values that could - cause problems (such as a hang or an abort) when a client connects. - - - The --bwlimit option may now be used in combination with --daemon - to specify both a default value for the daemon side and a value - that cannot be exceeded by a user-specified --bwlimit option. - - - Added the "port" parameter to the rsyncd.conf file. (Promoted from - the patches dir.) Also added "address". A command-line option - will take precedence over a config-file option, as expected. - - - In _exit_cleanup(): when we are exiting with a partially-received - file, we now flush any data in the write-cache before closing the - partial file. - - - The --inplace support was enhanced to work with --compare-dest, - --link-dest, and (the new) --copy-dest options. (Requires protocol - 29.) - - - Added the --dirs (-d) option for an easier way to copy directories - without recursion. - - - Added the --list-only option which is mainly a way for the client to - put the server into listing mode without needing to resort to any - option kluges (e.g. the age-old use of "-r --exclude="/*/*" for a - non-recursive listing). This option is used automatically when a - modern rsync speaks to a modern daemon, but may also be specified - manually if you want to force the use of the --list-only option over - a remote-shell connection. - - - Added the --omit-dir-times (-O) option which will avoid updating the - modified time for directories when --times was specified. This - option will avoid an extra pass through the file-list at the end of - the transfer (to tweak all the directory times), which can result in - an appreciable speedup for a really large transfer. (Promoted from - the patches dir.) - - - Added the --filter (-f) option and its helper option, -F. Filter - rules are an extension to the existing include/exclude handling - that also supports nested filter files as well as per-directory - filter files (like .cvsignore, but with full filter-rule parsing). - This new option was chosen in order to ensure that all existing - include/exclude processing remained 100% compatible with older - versions. Protocol 29 is needed for full filter-rule support, but - backward-compatible rules work with earlier protocol versions. - (Promoted from the patches dir.) - - - Added the --delay-updates option that puts all updated files into - a temporary directory (by default ".~tmp~", but settable via the - --partial-dir=DIR option) until the end of the transfer. This - makes the updates a little more atomic for a large transfer. - - - If rsync is put into the background, any output from --progress is - reduced. - - - Documented the "max verbosity" setting for rsyncd.conf. (This - setting was added a couple releases ago, but left undocumented.) - - - The sender and the generator now double-check the file-list index - they are given, and refuse to operate on a directory index (since - that would indicate that something had gone very wrong). - - - Added the --itemize-changes (-i) option that is a way to output the - list of files that got transferred and/or changed in any way, and how - they changed. The effect is the same as specifying --log-format - "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run. - - - Added the --fuzzy option, which attempts to find a basis file for a - file that is being created from scratch. The current algorithm - only looks in the destination directory for the created file, but - it does attempt to find a match based on size/mod-time (in case the - file was renamed with no other changes) as well as based on a fuzzy - name-matching algorithm. This option requires protocol 29 because - it needs the new file-sorting order. (Promoted from patches dir - and enhanced.) - - SUPPORT FILES: - - - Added support/atomic-rsync -- a perl script that will transfer some - files using rsync, and then move the updated files into place all at - once at the end of the transfer. Only works when pulling, and uses - --link-dest and a parallel hierarchy of files to effect its update. - - - Added support/mnt-excl that takes the /proc/mounts file and - translates it into a set of excludes that will exclude all mount - points (even mapped mounts to the same disk). The excludes are made - relative to the specified source dir and properly anchored. - - - Added support/savetransfer.c -- a C program that can make a copy of - all the data that flows over the wire. This lets you test for data - corruption (by saving the data on both the sending side and the - receiving side) or provides a way to help debug a protocol error. - - - Added support/rrsync -- my version of Joe Smith's restricted rsync - perl script. This helps to ensure that only certain rsync commands - can be run by an ssh invocation. - - - Improved the option descriptions in the --help text. + - Fixed an infinite loop bug when a filter rule was rejected due to being + overly long. - INTERNAL: + - When the server receives a --partial-dir option from the client, it no + longer runs the client-side code that adds an assumed filter rule (since + the client will be sending us the rules in the usual manner, and they + may have chosen to override the auto-added rule). - - Added better checking of the checksum-header values that come over - the socket. + ENHANCEMENTS: - - Merged the various delete-file functions into a single function so - that it is easier to maintain. + - Added the --log-file=FILE and --log-file-format=FORMAT options. These + can be used to tell any rsync to output what it is doing to a log file. + They work with a client rsync, a non-daemon server rsync (see the man + page for instructions), and also allows the overriding of rsyncd.conf + settings when starting a daemon. - - Improved the type of some variables (particularly blocksize vars) for - consistency and proper size. + - The --log-format option was renamed to be --out-format to avoid confusing + it with affecting the log-file output. (The old option remains as an + alias for the new to preserve backward compatibility.) - - Got rid of the uint64 type (which we didn't need). + - Made "log file" and "syslog facility" settable on a per-module basis in + the daemon's config file. - - Use a slightly more compatible set of core #include directives. + - Added the --remove-source-files option as a replacement for the (now + deprecated) --remove-sent-files option. This new option removes all + non-dirs from the source directories, even if the file was already + up-to-date. This fixes a problem where interrupting an rsync that + was using --remove-sent-files and restarting it could leave behind + a file that the earlier rsync synchronized, but didn't get to remove. + (The deprecated --remove-sent-files is still understood for now, and + still behaves in the same way as before.) - - Defined int32 in a way that ensures that the build dies if we can't - find a variable with at least 32 bits. + - Added the option --no-motd to suppress the message-of-the-day output + from a daemon when doing a copy. (See the manpage for a caveat.) - - The daemon's "read only" config item now sets an internal read_only - variable that makes extra sure that no write/delete calls on the - read-only side can succeed. + - Added a new environment variable to the pre-/post-xfer exec commands (in + the daemon's config file): RSYNC_PID. This value will be the same in + both the pre- and post-xfer commands, so it can be used if the pre-xfer + command wants to cache some arg/request info for the post-xfer command. - PROTOCOL DIFFERENCES FOR VERSION 29: + INTERNAL: - - If --inplace is specified, the generator sends an extra byte after - each index integer indicating what kind of basis file is being used - for the transfer (see the FNAMECMP_* defines). + - Did a code audit using IBM's code-checker program and made several + changes, including: replacing most of the strcpy() and sprintf() + calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to + an enum that had been intermingling a literal 0 with the defined enum + values, silencing some uninitialized memory checks, marking some + functions with a "noreturn" attribute, and changing an "if" that + could never succeed on some platforms into a pre-processor directive + that conditionally compiles the code. - - The sending of exclude names is done using filter-rule syntax. This - means that all names have a prefixed rule indicator, even excludes - (which used to be sent as a bare pattern, when possible). The -C - option will include the per-dir .cvsignore merge file in the list of - filter rules so it is positioned correctly (unlike in some older - transfer scenarios). + - Fixed a potential bug in f_name_cmp() when both the args are a + top-level "." dir (which doesn't happen in normal operations). - - Rsync sorts the filename list in a different way: it sorts the - subdir names after the non-subdir names for each dir's contents, and - it always puts a dir's contents immediately after the dir's name in - the list. (Previously an item named "foo.txt" would sort in between - directory "foo/" and "foo/bar".) + - Changed exit_cleanup() so that it can never return instead of exit. + The old code might return if it found the exit_cleanup() function + was being called recursively. The new code is segmented so that + any recursive calls move on to the next step of the exit-processing. - - When talking to a protocol 29 rsync daemon, a list-only request - is able to note this before the options are sent over the wire, and - the new --list-only option is enabled. + - The macro WIFEXITED(stat) will now be defined if the OS didn't already + define it. - - When the --stats bytes are sent over the wire (or stored in a batch), - they now include two elapsed-time values: one for how long it took to - build the file-list, and one for how long it took to send it over the - wire (each expressed in thousandths of a second). + DEVELOPER RELATED: - - When --delete-excluded is specified with some filter rules (AKA - excludes), a client sender will still initiate a send of the filter - rules to the receiver, but it only includes those rules that are - receiver-specific. Older protocols used to omit the sending of - excludes in this situation (since there were no receiver-specific - rules that survived --delete-excluded back then). + - The acls.diff and xattrs.diff patches have received a bunch of work to + make them much closer to being acceptable in the main distribution. + The xattrs patch also has some preliminary Mac OS X compatibility code + that allows Macs and non-macs to exchange extended attributes. - - A protocol-29 batch file includes a bit for the setting of the --dirs - option. Also, the shell script created by --write-batch will use the - --filter option instead of --exclude-from to capture any filter rules. + - A new diff in the patches dir, fake-root.diff, allows rsync to + maintain a backup hierarchy with full owner, group, and device info + without actually running as root. It does this using a special + extended attribute, so it depends on xattrs.diff (which depends on + acls.diff). - BUILD CHANGES: + - The rsync.yo and rsyncd.conf.yo files have been updated to work + better with the latest yodl 2.x releases. - - Handle an operating system that use mkdev() in place of makedev(). + - Updated config.guess and config.sub to their 2006-02-23 version. - - Improved configure to better handle cross-compiling. + - Updated various files to include the latest FSF address and to have + consistent opening comments.
