(Fix derived from the cygwin's rsync package.) - - - Fixed a potential hang when verbosity is high, the client side is - the sender, and the file-list is large. - - - 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 no longer affects symlinks - that are being copied, even if they point nowhere. - - - 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. + - Fixed the output of -ii when combined with one of the --*-dest options: + it now itemizes all the items, not just the changed ones. - - One call to flush_write_file() was not being checked for an error. + - Made the output of all file types consistent when using a --*-dest + option. Prior versions used to output too many creation events for + matching items. - - The --no-relative option was not being sent from the client to a - server sender. + - The code that waits for a child pid now handles being interrupted by + a signal. This fixes a problem with the pre-xfer exec function not + being able to get the exit status from the script. - - 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). + - A negated filter rule now sends the negation option when sending the + filter rules. - - 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). - - - A local transfer no longer duplicates all its include/exclude options - by sending the forked process a copy of the list it already has. + - Fixed a problem with -vv (double --verbose) and --stats when "pushing" + files (which includes local copies). Version 2.6.9 would complete the + copy, but exit with an error when the receiver output its memory stats. 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 (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. + - Added the --delete-delay option, which is a more efficient way to + delete files at the end of the transfer without needing a separate + delete pass. + + - You may specify --max-delete=0 to a 3.0.0 client as long as the + receiving side is at least version 3.0.0. This means that you + can pull from an older rsync with this option, but pushing to an + older rsync will generate an error. *Be sure to never specify a 0 + value to an older rsync client, or it will be silently ignored.* + + - The --hard-link option now uses less memory on both the sending and + receiving side for all protocol versions. For protocol 30, the use + of a hashtable on the sending side allows us to more efficiently + convey to the receiver what files are linked together. This reduces + the amount of data sent over the socket by a considerable margin, and + moves the in-memory storage of the device+inode information from the + receiving side (for protocols < 30) to the sending side (note that + older rsync versions kept the device+inode information on both + sides). INTERNAL: - - Added better checking of the checksum-header values that come over - the socket. - - - Merged the various delete-file 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: - - - 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). - - - 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".) + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. - - 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. + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - - 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). + - Added missing prototypes for compatibility functions from the lib dir. - - 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). + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - - 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. + - Made the sending of some numbers more efficient for protocol 30. - BUILD CHANGES: + - Improved the use of "const" on pointers. - - Handle an operating system that use mkdev() in place of makedev(). + DEVELOPER RELATED: - - Improved configure to better handle cross-compiling. + - ...
