(Fix derived from the cygwin's rsync package.) + - Fixed the working of --fake-super with --link-dest and --xattrs. - - Fixed a potential hang when verbosity is high, the client side is - the sender, and the file-list is large. + - Fixed a hang when combining --dry-run with --remove-source-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 with --iconv's handling of files that cannot be converted: + a failed name can no longer cause a transfer failure. - - Fixed an off-by-one error in the handling of --max-delete=N. + - Fixed the building of the rounding.h file on systems that need custom + CPPFLAGS to be used. Also improved the error reporting if the building + of rounding.h fails. - - One place in the code wasn't checking if fork() failed. + - Fixed the use of the --protect-args (-s) option when talking to a daemon. - - The "ignore nonreadable" daemon parameter no longer affects symlinks - that are being copied, even if they point nowhere. + - Fixed the --ignore-existing option's protection of files on the receiver + that are non-regular files on the sender (e.g. if a symlink or a dir on + the sender is trying to replace a file on the receiver). The reverse + protection (protecting a dir/symlink/device from being replaced by a + file) was already working. - - 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. + - Fixed an assert failure if --hard-links is combined with an option that + can skip a file in a set of hard-linked files (i.e. --ignore-existing, + --append, etc.), without skipping all the files in the set. - - 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. + - Avoid setting the modify time on a directory that already has the right + modify time set. This avoids tweaking the dir's ctime. - - 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. + - Improved the daemon-exclude handling to do a better job of applying the + exclude rules to path entries. It also sends the user an error just as + if the files were actually missing (instead of silently ignoring the + user's args), and avoids sending the user the filter-action messages + for these non-user-initiated rules. - - One call to flush_write_file() was not being checked for an error. + - Fixed some glitches with the dry-run code's missing-directory + handling, including a problem when combined with --fuzzy. - - The --no-relative option was not being sent from the client to a - server sender. + - Fixed some glitches with the skipped-directory handling. - - 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 the 'T'-flag itemizing of symlinks when --time isn't preserved. - - 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). + - Fixed a glitch in the itemizing of permissions with the -E option. - - A local transfer no longer duplicates all its include/exclude options - by sending the forked process a copy of the list it already has. + - The --append option's restricting of transfers to those that add data no + longer prevents the updating of non-content changes to otherwise up-to- + date files (i.e. those with the same content but differing permissions, + ownership, xattrs, etc.). - ENHANCEMENTS: + - Don't allow --fake-super to be specified with -XX (double --xattrs) + because the options conflict. If a daemon has "fake super" enabled, + it automatically downgrades a -XX request to -X. - - 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. Also 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 a couple bugs in the parsing of daemon-config excludes that could + make a floating exclude rule get treated as matching an absolute path. - INTERNAL: + - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support + wasn't compiled in to the daemon (avoiding a warning in the logs). - - Added better checking of the checksum-header values that come over - the socket. + - Fixed the inclusion of per-dir merge files from implied dirs. - - Merged the various delete-file functions into a single function so - that it is easier to maintain. + - Fixed the support/rrsync script to work with the latest options that + rsync sends (including its flag-specifying use of -e to the server). - - Improved the type of some variables (particularly blocksize vars) for - consistency and proper size. + ENHANCEMENTS: - - Got rid of the uint64 type (which we didn't need). + - Added the --old-dirs (--old-d) option to make it easier for a user to + ask for file-listings with older rsync versions (this is easier than + having to type "-r --exclude='/*/*'" manually). - - Use a slightly more compatible set of core #include directives. + - When getting an error while asking an older rsync daemon for a file + listing, rsync will try to notice if the error is a rejection of the + --dirs (-d) option and let the user know how to work around the issue. - - Defined int32 in a way that ensures that the build dies if we can't - find a variable with at least 32 bits. + - Added a few more --no-OPTION overrides. - - 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. + - Improved the documentation of the --append option. - PROTOCOL DIFFERENCES FOR VERSION 29: + - Improved the documentation of the filter/exclude/include daemon + parameters. + + 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). + - Fixed a couple minor bugs in the included popt library (ones which I + sent to the official popt project for inclusion in the 1.14 release). - - 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 stat() call that should have been do_stat() so that the proper + normal/64-bit stat() function gets called. (Was in an area that should + not have caused problems, though.) - - 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 the file-glob code to do a directory scan without using the + "glob" and "glob.h". This lets us do the globbing with less memory + churn, and also avoid adding daemon-excluded items to the returned + args. - - 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. + DEVELOPER RELATED: - - 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). + - The configure script tries to get the user's compiler to not warn about + unused function parameters if the build is not including one or more of + the ACL/xattrs/iconv features. - - 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 configure script now has better checks for figuring out if the + included popt code should be used or not. - - 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. + - Fixed two testsuite glitches: avoid a failure if someone's "cd" command + outputs the current directory when cd-ing to a relative path, and made + the itemized test query how rsync was built to determine if it should + expect hard-linked symlinks or not. - BUILD CHANGES: + - Updated the testsuite to verify that various bug fixes remain fixed. - - Handle an operating system that use mkdev() in place of makedev(). + - The RPM spec file was updated to have: (1) comments for how to use the + rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file. - - Improved configure to better handle cross-compiling. + - Updated the build scripts to work with a revised FTP directory + structure.
