-NEWS for rsync 2.6.7 (UNRELEASED)
-Protocol: 29 (unchanged)
-Changes since 2.6.6:
-
- OUTPUT CHANGES:
-
- - The itemized output now uses 'S' for a special file instead of
- clumping them together with the 'D' for devices. The number of
- characters is also different (to remove an unused field).
-
- - The way rsync escapes unreadable characters has changed. First, rsync
- now has support for recognizing valid multibyte character sequences in
- your current locale, allowing it to escape fewer characters than before
- for a locale such as UTF-8. Second, it now uses an escape idiom of
- "\#123", which is the literal string "\#" followed by exactly 3 octal
- digits. Rsync no longer doubles a backslash character in a filename
- (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
- escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
- (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also
- the --8-bit-output (-8) option, mentioned below.
-
- Script writers: the local rsync is the one that outputs escaped names,
- so if you need to support unescaping of filenames for older rsyncs, I'd
- suggest that you parse the output of "rsync --version" and only use the
- old unescaping rules for 2.6.5 and 2.6.6.
+NEWS for rsync 3.0.0 (UNRELEASED)
+Protocol: 30 (changed)
+Changes since 2.6.9:
- BUG FIXES:
-
- - Fixed a really old bug that caused --checksum (-c) to checksum all the
- files encountered during the delete scan (ouch).
+ NOTABLE CHANGE IN BEHAVIOR:
- - Fixed a potential hang in a remote generator: when the receiver gets a
- read-error on the socket, it now signals the generator about this so that
- the generator does not try to send any of the terminating error messages
- to the client (avoiding a potential hang in some setups).
+ - The handling of implied directories when using --relative has changed
+ to send them as directories (e.g. no implied dir is ever sent as a
+ symlink). This avoids unexpected behavior and should not adversely
+ affect most people. If you're one of those rare people who relied
+ upon having an implied dir be duplicated as a symlink, either specify
+ --keep-dirlinks or --no-implied-dirs.
- - Made hard-links work with symlinks and devices again.
+ BUG FIXES:
- - 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).
+ - Fixed the output of -ii when combined with one of the --*-dest options:
+ it now itemizes all the items, not just the changed ones.
- - If a device-file/special-file changes permissions, rsync now updates the
- permissions without recreating the file.
+ - 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.
- - 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.
+ - 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.
- - 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.
+ - A negated filter rule (with a '!' modifier) no longer loses the negation
+ when sending the filter rules to the remote rsync.
- - Reject the combination of --inplace and --sparse since the sparse-output
- algorithm doesn't work when overwriting existing data.
+ - Fixed a problem with the --out-format (aka --log-format) option %f: it
+ would output superfluous directory information for a non-daemon rsync.
- - Fixed the directory name in the error that is output when pop_dir()
- fails.
+ - 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.
- - Really fixed the parsing of a "!" entry in .cvsignore files this time.
+ - If --password-file is used on a non-daemon transfer, rsync now complains
+ and exits. This should help users figure out that they can't use this
+ option to control a remote shell's password prompt.
- - 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).
+ - Make sure that directory permissions of a newly-created destination
+ directory are handled right when --perms is left off.
- - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
- the exit status properly and generate a better error.
+ - The itemized output of a newly-created destination directory is now
+ output as a creation event, not a change event.
- - Fixed some glitches in the double-verbose output when using --copy-dest,
- --link-dest, or --compare-dest.
+ - Improved --hard-link so that more corner cases are handled correctly
+ when combined with options such as --link-dest and/or --ignore-existing.
- - Fixed the matching of the dont-compress items (e.g. *.gz) against files
- that have a path component containing a slash.
+ - The --append option no longer updates a file that has the same size.
- - 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 when combining --backup and --backup-dir with --inplace:
+ any missing backup directories are now created.
- - 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.
+ - Fixed a bug when using --backup and --inplace with --whole-file or
+ --read-batch: backup files are actually created now.
- - 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.
+ - Starting up an extra copy of an rsync daemon does not delete the pidfile
+ for the running daemon -- if the pidfile exists, the extra program will
+ exit with an error.
- - Got rid of the need for --force to be used in some circumstances with
- --delete-after (making it consistent with --delete-before/-during).
+ - The daemon pidfile is checked and created sooner in the startup sequence.
ENHANCEMENTS:
- - 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).
-
- - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
- high-bit characters that it thinks are unreadable in the current locale.
-
- - The new option --human-readable (-h) changes the output of --progress,
- --stats, and the end-of-run summary to be easier to read. If repeated,
- the units become powers of 1024 instead of powers of 1000.
-
- - 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 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.)
-
- - 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).
-
- - 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.
-
- - Added the --chmod=MODE option that allows the destination permissions to
- be changed from the source permissions. E.g. --chmod=g+w,o-rwx
-
- - 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.
+ - A new incremental-recursion algorithm is now used when rsync is talking
+ to another 3.x version. This starts the transfer going more quickly
+ (before all the files have been found), and requires much less memory.
+ See the --recursive option in the manpage for some restrictions.
+
+ - Saved memory in the non-incremental-recursion algorithm for typical
+ option values (usually saving from 21-29 bytes per file).
+
+ - The default --delete algorithm is now --delete-during when talking to a
+ 3.x rsync. This is a faster scan than using --delete-before (which is
+ the default when talking to older rsync versions), and is compatible with
+ the new incremental recursion mode.
+
+ - Rsync now allows multiple remote-source args to be specified rather than
+ having to rely on a special space-splitting side-effect of the remote-
+ shell. Additional remote args must specify the same host or have an
+ empty hostname, as seen here: :file1 ::module/file2. This means that
+ local use of brace expansion now works: rsync -av host:path/{f1,f2} .
+
+ - 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.
+
+ - Added the --acls (-A) option to preserve Access Control Lists. This is
+ an improved version of the prior patch that was available, and it even
+ supports OS X ACLs. (If you need to have backward compatibility with
+ old, patched versions of rsync, apply the acls.diff file from the patches
+ dir.)
+
+ - Added the --xattrs (-X) option to preserver extended attributes. This is
+ an improved version of the prior patch that was available. (If you need
+ to have backward compatibility with old, patched versions of rsync, apply
+ the xattrs.diff file from the patches dir.)
+
+ - Added the --fake-super option that allows a non-super user to preserve
+ all attributes of a file by using a special extended-attribute idiom.
+ There is also an analogous "fake super" option for an rsync daemon.
+
+ - Added the --iconv option, which allows rsync to convert filenames from
+ one character-set to another during the transfer. The default is to make
+ this feature available as long as your system has iconv_open(). If
+ compilation fails, specify --disable-iconv to configure, and then
+ rebuild. If you want rsync to perform character-set conversions by
+ default, you can specify --enable-iconv=CONVERT_STRING with the default
+ value for the --iconv option that you wish to use. For example,
+ --enable-iconv=. is a good choice. See the rsync manpage for an
+ explanation of the --iconv option's settings.
+
+ - Added the --skip-compress=LIST option to override of the default list of
+ file suffixes that will not be compressed when using --compress.
+
+ - The daemon's default for "dont compress" was extended to include:
+ *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
+ The matching routine was also optimized to run more quickly.
+
+ - The --max-delete option now outputs a warning if it skipped any file
+ deletions, including a count of how many deletions were skipped. (Older
+ versions just silently stopped deleting things.)
+
+ - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
+ about extraneous files without deleting anything. If you're not sure
+ what version the client is, you can use the less-obvious --max-delete=-1,
+ as both old and new versions will treat that as the same request (though
+ older versions don't warn).
+
+ - 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 (rather than adding more
+ data), and limits the in-memory storage of the device+inode information
+ to just the sending side for the new protocol 30, or to the receiving
+ side when speaking an older protocol (note that older rsync versions kept
+ the device+inode information on both sides).
+
+ - The filter rules now support a perishable ("p") modifier that marks rules
+ that should not have an effect in a directory that is being deleted. e.g.
+ -f '-p .svn/' would only affect "live" .svn directories.
+
+ - If we get an error setting the time on a symlink, we don't complain about
+ it anymore (since some operating systems don't support that, and it's not
+ that important).
+
+ - Protocol 30 now uses MD5 checksums instead of MD4.
+
+ - If a daemon module's "path" value is not an absolute pathname, the code
+ now makes it absolute internally (making it work properly).
+
+ - Changed the --append option to not checksum the existing data in the
+ destination file, which speeds up file appending.
+
+ - Added the --append-verify option, which works like the older --append
+ option (verifying the existing data in the destination file). For
+ compatibility with older rsync versions, any use of --append that is
+ talking protocol 29 or older will revert to the --append-verify method.
+
+ - Documented and extended the support for the RSYNC_CONNECT_PROG variable
+ that can be used to enhance the client side of a daemon connection.
+
+ - Added the --protect-args (-s) option, that tells rsync to send most of
+ the command-line args at the start of the transfer rather than as args
+ to the remote-shell command. This protects them from space-splitting,
+ and only interprets basic wildcard special shell characters (*?[).
+
+ - Improved the dashes and double-quotes in the nroff manpage output.
+
+ - We now support a lot more --no-OPTION override options.
- - 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).
-
- - 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.
-
- - A new option, --executability (-E) can be used to preserve just the
- execute bit on files, for those times when using the --perms option is
- not desired.
-
- - The daemon now logs each module-list request it receives.
-
- - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
- (permission bits, e.g. "rwxr-xrwt").
+ INTERNAL:
- - The --dry-run option no longer forces the enabling of --verbose.
+ - The file-list sorting algorithm now uses a sort that keeps any same-
+ named items in the same order as they were specified. This allows
+ rsync to always ensure that the first of the duplicates is the one
+ that will be included in the copy. The new sort was also faster
+ than the glibc version of qsort() and mergesort() in my testing.
- - Some minor documentation improvements.
+ - Rsync now supports the transfer of 64-bit timestamps (time_t values).
- - Updated some diffs in the patches dir.
+ - Fixed a build problem with older (2.x) versions of gcc.
- INTERNAL:
+ - Added some isType() functions that make dealing with signed characters
+ easier without forcing variables via casts.
- - We now use sigaction() and sigprocmask() if possible, and fall back on
- signal() if not. Using sigprocmask() ensures that rsync enables all the
- signals that it needs, just in case it was started in a masked state.
+ - Changed strcat/strcpy/sprintf function calls to use safer versions.
- - Some buffer sizes were expanded a bit, particularly on systems where
- MAXPATHLEN is overly small (e.g. cygwin).
+ - Upgraded the included popt version to 1.10.2 and improved its use of
+ string-handling functions.
- - If io_printf() tries to format more data than fits in the buffer, exit
- with an error instead of transmitting a truncated buffer.
+ - Added missing prototypes for compatibility functions from the lib dir.
- - If a va_copy macro is defined, lib/snprintf.c will use it when defining
- the VA_COPY macro.
+ - Configure determines if iconv() has a const arg, allowing us to avoid a
+ compiler warning.
- - Reduced the amount of stack memory needed for each level of directory
- recursion by nearly MAXPATHLEN bytes.
+ - Made the sending of some numbers more efficient for protocol 30.
- - 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.
+ - Make sure that a daemon process doesn't mind if the client was weird and
+ omitted the --server option.
- - 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.
+ - Improved the use of "const" on pointers.
- - Unified the f_name() and the f_name_to() functions.
+ - Improved J.W.'s pool_alloc routines to add a way of freeing older
+ sections of a pool's memory.
DEVELOPER RELATED:
- - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
- the previous -p0. Also, the version included in the release tar now
- affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
- it is no longer necessary to run autoconf and/or yodl unless you're
- applying a patch that was checked out from CVS.
-
- - 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.
+ - Rsync is now licensed under the GPLv3 or later.
- - There is a new script, "prepare-source" than can be used to update the
- various generated files (proto.h, configure, etc.) even before configure
- has created the Makefile (this is mainly useful when patching the source
- with a patch that doesn't affect generated files).
+ - When running the tests, we now put our per-test temp dirs into a sub-
+ directory named testtmp (which is created, if missing). This allows
+ someone to symlink the testtmp directory to another filesystem (which is
+ useful if the build dir's filesystem does not support ACLs and xattrs,
+ and another file system does).
- - The testsuite now sets HOME so that it won't be affected by a file such
- as ~/.popt.
+ - Rsync now has a way of handling protocol-version changes during the
+ development of a new protocol version. This exchange of sub-version
+ info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking
+ in older versions (since we'd quickly exceed the MAX_PROTOCOL_VERSION
+ if we incremented the main PROTOCOL_VERSION value for every minor
+ change during development).
