Only affects a daemon if it allows uploads and does not refuse + the --compress option. - - The --stats output will contain file-list time-statistics if both - sides are 2.6.4, or if the local side is 2.6.4 and the files are - being pushed (since the stats come from the sending side). - (Requires protocol 29 for a pull.) - BUG FIXES: - - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3 - was only treating it as a special token in an rsync include/exclude - file). + - The setting of flist->high in clean_flist() was wrong for an empty list. + This could cause flist_find() to crash in certain rare circumstances + (e.g. if just the right directory setup was around when --fuzzy was + combined with --link-dest). - - The combination of --verbose and --dry-run now mentions the full list - of changes that would be output without --dry-run. + - The outputting of hard-linked files when verbosity was > 1 was not right: + without -i it would output the name of each hard-linked file as though + it had been changed (it now outputs a "is hard linked" message for the + file); with -i it would output all dots for the unchanged attributes of + a hard-link (it now changes those dots to spaces, as is done for other + totally unchanged items). - - Avoid a mkdir warning when removing a directory in the destination - that already exists in the --backup-dir. + - When backing up a changed symlink or device, get rid of any old backup + item so that we don't get an "already exists" error. - - An OS that has a binary mode for its files (such as cygwin0 needed - setmode(fd, O_BINARY) called on the temp-file we opened with - mkstemp(). (Fix derived from the Cygwin's 2.6.3 rsync package.) + - A couple places that were comparing a local and a remote modification- + time were not honoring the --modify-window option. - - Fixed a potential hang when verbosity is high, the client side is - the sender, and the file-list is large. + - Fixed a really old, minor bug that could cause rsync to warn about being + unable to mkdir() a path that ends in "/." because it just created the + directory (required --relative, --no-implied-dirs, a source path that + ended in either a trailing slash or a trailing "/.", and a non-existing + destination dir to tickle the bug in a recent version). - - 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 an off-by-one error in the handling of --max-delete=N. - - - One place in the code wasn't checking if fork() failed. - - - The "ignore nonreadable" daemon parameter used to erroneously affect - symlinks that pointed to a non-existent file. This has been fixed. - - - 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. - - - 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. - - - 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. - - - One call to flush_write_file() was not being checked for an error. - - - The --no-relative option was not being sent from the client to a - server sender. - - - 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). - - - If a daemon can't open the specified log file (i.e. syslog is not - being used), die without crashing. We also output an error about - the failure on stderr (which will only be seen if --no-detach was - specified). - - - A local transfer no longer duplicates all its include/exclude options - (since the forked process already has a copy of the exclude list, - there's no need to send them a set of duplicates). + - If the user specifies a remote-host for both the source and destination, + we now output a syntax error rather than trying to open the destination + hostspec as a filename. ENHANCEMENTS: - - 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. This makes it more efficient than the - default, before-the-transfer behavior, which is now available as - --delete-before (this is the default --delete-WHEN option that will - be chosen if --delete or --delete-excluded is specified without a - --delete-WHEN choice). All the --del* options infer --delete, so an - rsync daemon that refuses "delete" will still refuse to allow any - file-deleting options. - - - 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 (e.g. 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 - internal option kluges (e.g. the age-old use of "-r --exclude="/*/*" - for a non-recursive listing). This option is used automatically - (behind the scenes) 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 and enhanced.) - - - 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. + - Made the "max verbosity" setting in the rsyncd.conf file settable on a + per-module basis (which now matches the documentation). - - Documented the "max verbosity" setting for rsyncd.conf. (This - setting was added a couple releases ago, but left undocumented.) + - The support/rrsync script has been upgraded to verify the args of options + that take them (instead of rejecting any such options). The script was + also changed to try to be more secure and to fix a problem in the parsing + of a pull operation that has multiple sources. - - The sender and the generator now double-check the file-list index - they are given, and refuse to try to do a file transfer on a - non-file index (since that would indicate that something had gone - very wrong). - - - Added the --itemize-changes (-i) option, which is a way to output a - more detailed list of what files changed in any way and how they - changed. The effect is the same as specifying a --log-format of - "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run too. - - - 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.) - - - Improved the option descriptions in the --help text. - - SUPPORT FILES: - - - Added atomic-rsync to the support dir: 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 mnt-excl to the support dir: a perl script 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 savetransfer.c to the support dir: 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 rrsync to the support dir: this is 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. - - INTERNAL: - - - Added better checking of the checksum-header values that come over - the socket. - - - Merged a variety of file-deleting functions into a single function so - that it is easier to maintain. - - - Improved the type of some variables (particularly blocksize vars) for - consistency and proper size. - - - Got rid of the uint64 type (which we didn't need). - - - Use a slightly more compatible set of core #include directives. - - - Defined int32 in a way that ensures that the build dies if we can't - find a variable with at least 32 bits. - - - 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. - - PROTOCOL DIFFERENCES FOR VERSION 29: - - - A 16-bit flag-word is transmitted after every file-list index. This - indicates what is changing between the sender and the receiver. The - generator now transmits an index and a flag-word to indicate when - dirs and symlinks have changed (resorting to the old-style outputting - of local change-messages for older protocols). - - - If --inplace is specified, the generator sends an extra byte after - the flag-word indicating what kind of basis file is being used for - the transfer (see the FNAMECMP_* defines). This information is used - to optimize the transfer when the basis file is not the destination. - - - 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). - - - 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".) - - - 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 encluded in the options sent over the - socket. - - - 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). - - - When --delete-excluded is specified with some filter rules (AKA - excludes), a client sender will now initiate a send of the filter - rules to the receiver (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). Note that, as with - all the filter-list sending, only items that are significant to the - other side will actually be sent over the wire, so the filter-rule - list is often empty in this scenario. - - - 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. + - Upgraded the zlib code from 1.1.4 to 1.2.2 (plus the security fix + mentioned above). BUILD CHANGES: - - Handle an operating system that use mkdev() in place of makedev(). + - Made configure define NOBODY_USER (currently hard-wired to "nobody") and + NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we + find in the /etc/group file). + + - Added a test to the test suite, itemized.test, that tests the output of + -i (log-format w/%i) and some double-verbose messages. - - Improved configure to better handle cross-compiling.
