The number of + characters is also different (to remove an unused field). BUG FIXES: - - Fixed a crash bug that might appear when --delete was used and - multiple source directories were specified. + - Fixed a really old bug that caused --checksum (-c) to checksum all the + files encountered during the delete scan (ouch). + + - Made hard-links work with symlinks and devices again. + + - If the sender gets an early EOF reading a source file, we propagate this + error to the receiver so that it can discard the file and try requesting + it again (which is the existing behavior for other kinds of read errors). - - The --backup code no longer attempts to create some directories - over and over again (generating warnings along the way). + - If a device-file/special-file changes permissions, rsync now updates the + permissions without recreating the file. - - Fixed a bug in the reading of the secrets file (by the daemon) and - the password file (by the client): the files no longer need to be - terminated by a newline for their content to be read in. + - 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. - - If a file has a read error on the sending side, the receiver will - no longer keep the resulting file unless the --partial option was - specified. (Note: both sides must be running 2.6.3 for this to - work -- older receivers always keep the file, and older senders - don't tell the receiver that the file was not read correctly.) + - When --inplace creates a new destination file, rsync now creates it with + permissions 0600 instead of 0000 -- this makes restarting possible when + the transfer gets interrupted in the middle of sending a new file. - - If a file gets resent in a single transfer and the --backup option - is enabled, rsync no longer performs a duplicate backup (losing the - original file in the process). + - Reject the combination of --inplace and --sparse since the sparse-output + algorithm doesn't work when overwriting existing data. - - Fixed an age-old crash problem with --read-batch on a local copy - (rsync was improperly assuming --whole-file for the local copy). + - Fixed the directory name in the error that is output when pop_dir() + fails. - - Files specified in the daemon's "exclude" or "exclude from" config - items are now excluded from being uploaded (assuming that the module - allows uploading at all) in addition to the old download exclusion. + - Really fixed the parsing of a "!" entry in .cvsignore files this time. - - Got rid of a potential hang in the receiver when near the end of a - phase. + - If the generator gets a stat() error on a file, output it (this used to + require at least -vv for the error to be seen). - - When using --backup without a --backup-dir, rsync no longer preserves - the modify time on directories. This avoids confusing NFS. + - If waitpid() fails or the child rsync didn't exit cleanly, we now handle + the exit status properly and generate a better error. - - When --copy-links (-L) is specified, we now output a separate error - for a symlink that has no referent instead of claiming that a file - "vanished". + - Fixed some glitches in the double-verbose output when using --copy-dest, + --link-dest, or --compare-dest. - - Error messages from the daemon server's option-parsing (such as - refused options) now get sent back to the client (the server used - to just exit because the socket wasn't in the right state to send - the message). + - Fixed the matching of the dont-compress items (e.g. *.gz) against files + that have a path component containing a slash. - - Most errors that occur during a daemon transfer are now returned to - the user in addition to being logged (some messages are intended to - be daemon-only). + - If code reading a filter/exclude file an EINTR error, rsync now clears + the error flag on the file handle so it can keep on reading. - - Fixed a bug in the daemon authentication code when using one of the - batch-processing options. + - If --relative is active, the sending side cleans up trailing "/" or "/." + suffixes to avoid triggering a bug in older rsync versions. Also, we now + reject a ".." dir if it would be sent as a relative dir. + + - If a non-directory is in the way of a directory and rsync is run with + --dry-run and --delete, rsync no longer complains about not being able + to opendir() the not-yet present directory. + + - Got rid of the need for --force to be used in some circumstances with + --delete-after (making it consistent with --delete-before/-during). ENHANCEMENTS: - - Added --keep-dirlinks (-K), which allows you to symlink a directory - onto another patition on the receiving side and have rsync treat it - as matching a normal directory from the sender. + - Added the --specials option to tell rsync to copy special files (and does + not require root). The --devices option now affects just character and + block devices (which now matches the documentation). The -D option still + requests both --devices and --specials, and -a still implies -D. + + - Added the --append option that makes rsync append data onto files that + are longer on the source than the destination (this includes new files). + + - Added the --min-size=SIZE option to exclude small files from the + transfer. + + - Added the --compress-level option to allow you to set how aggressive + rsync's compression should be (this option implies --compress). + + - Enhanced the parsing of the SIZE value for --min-size and --max-size to + allow easy entry of multiples of 1000 (instead of just multiples of 1024) + and off-by-one values too (e.g. --max-size=8mb-1). + + - The options --human-readable (-h) and --si change the output of the + --stats and the end-of-run summary to be easier to read. + + - If lutimes() and/or lchmod() are around, use them to allow the + preservation of attributes on symlinks. + + - The --link-dest option now affects symlinks and devices (when possible). + + - Improved the output of hard-linked and copied files when using + --link-dest, --copy-dest, or --compare-dest. - - Added the "write only" option to the daemon's config file. + - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and + "post-xfer exec". These allow a command to be specified on a per-module + basis that will be run before and/or after a daemon-mode transfer. (See + the manpage for a list of the environment variables that are set with + information about the transfer.) - - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) - and documented all these options in the man page. + - When using the --relative option, you can now insert a dot dir in + the source path to indicate where the replication of the source dirs + should start. For example, if you specify a source path of + rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only + replicate the "baz/dir" part of the source path (note: a trailing + dot dir is unaffected unless it also has a trailing slash). - - If the daemon get an address-in-use error starting up, we sometimes - suggest that the user specify --ipv4 or --ipv6 to work around their - buggy socket implementation. + - Added some new --no-FOO options that make it easier to override unwanted + implied or default options. For example, "-a --no-o" (aka "--archive + --no-owner") can be used to turn off the preservation of file ownership + that is implied by -a. - - Improved the handling of the --bwlimit option so that it's less - bursty, more accurate, and works properly over a larger range of - values. + - Added the --chmod=MODE option that allows the destination permissions to + be changed from the source permissions. E.g. --chmod=g+w,o-rwx - - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and - SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address. + - Added the "incoming chmod" and "outgoing chmod" daemon options that allow + a module to specify what permissions changes should be applied to all + files copied to and from the daemon. - - Added the --checksum-seed=N option for advanced users. + - Allow the --temp-dir option to be specified when starting a daemon, which + sets the default temporary directory for incoming files. + + - If --delete is combined with --dirs without --recursive, rsync will now + delete in any directory whose content is being synchronized. + + - If --backup is combined with --delete without --backup-dir (and without + --delete-excluded), we add a "protect" filter-rule to ensure that files + with the backup suffix are not deleted. + + - The file-count stats that are output by --progress were improved to + better indicate what the numbers mean. For instance, the output: + "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file + to be transferred, and we still need to check 8383 more files out of + a total of 9999. + + - The include/exclude code now allows a dir/*** directive (with 3 trailing + stars) to match both the dir itself as well as all the content below the + dir (dir/** would not match the dir). + + - Added the --prune-empty-dirs (-m) option that makes the receiving rsync + discard empty chains of directories from the file-list. This makes it + easier to selectively copy files from a source hierarchy and end up with + just the directories needed to hold the resulting files. + + - If the --itemize-changes (-i) option is repeated, rsync now includes + unchanged files in the itemized output (similar to -vv, but without all + the other verbose messages that can get in the way). Of course, the + client must be version 2.6.7 for this to work, but the remote rsync only + needs to be 2.6.7 if you're pushing files. + + - Added the --super option to make the receiver always attempt super- user + activities. This is useful for systems that allow things such as devices + to be created or ownership to be set without being UID 0, and is also + useful for someone who wants to ensure that errors will be output if the + receiving rsync isn't being run as root. + + - Added the --sockopts option for those few who want to customize the TCP + options used to contact a daemon rsync. + + - Added a way for the --temp-dir option to be combined with a partial-dir + setting that lets rsync avoid non-atomic updates (for those times when + --temp-dir is not being used because space is tight). + + - Some minor documentation improvements. + + - Updated some diffs in the patches dir. + + - A new support script, files-to-excludes, will transform a list of files + into a set of include/exclude directives that will copy those files. INTERNAL: - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. + - Some buffer sizes were expanded a bit, particularly on systems where + MAXPATHLEN is overly small (e.g. cygwin). - - Use rsyserr() in the various places that were still calling - rprintf() with strerror() as an arg. + - If io_printf() tries to format more data than fits in the buffer, exit + with an error instead of transmitting a truncated buffer. - - If an rsync daemon is listening on multiple sockets (to handle both - IPv4 and IPv6 to a single port), we now close all the unneeded file - handles after we accept a connecton (we used to close just one of - them). + - If a va_copy macro is defined, lib/snprintf.c will use it when defining + the VA_COPY macro. - BUILD CHANGES: + - Reduced the amount of stack memory needed for each level of directory + recursion by nearly MAXPATHLEN bytes. - - Added a "gen" target to rebuild most of the generated files, - including configure, config.h.in, the man pages, and proto.h. + - The wildmatch function was extended to allow an array of strings to be + supplied as the string to match. This allows the exclude code to do less + string copying. - - If "make proto" doesn't find some changes in the prototypes, the - proto.h file is left untouched (its timestamp used to always be - updated). + - Got rid of the safe_fname() function (and all the myriad calls) and + replaced it with a new function in the log.c code that filters all the + output going to the terminal. - - The variable $STRIP (that is optionally set by the install-strip - target's rule) was changed to $INSTALL_STRIP because some systems - have $STRIP set in the environment. + - Unified the f_name() and the f_name_to() functions. DEVELOPER RELATED: - - The scripts in the testsuite dir were cleaned up a bit. - - - Some new diffs were added to the patches dir, and some accepted - ones were removed. + - Several diffs in the patches dir now use the proper --enable-FOO + configure option instead of --with-FOO to turn on the inclusion of + the newly patched feature. + - The testsuite now sets HOME so that it won't be affecting by a file + such as ~/.popt.
