-rsync 2.5.1 (2002-01-03)
+NEWS for rsync 2.6.9 (6 Nov 2006)
+Protocol: 29 (unchanged)
+Changes since 2.6.8:
+
+ BUG FIXES:
+
+ - If rsync is interrupted via a handled signal (such as SIGINT), it will
+ once again clean-up its temp file from the destination dir.
+
+ - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
+ --copy-dest, and --compare-dest options to a daemon without chroot: if
+ the copy's destination dir is deeper than the top of the module's path,
+ these options now accept a safe number of parent-dir (../) references
+ (since these options are relative to the destination dir). The old code
+ incorrectly chopped off all "../" prefixes for these options, no matter
+ how deep the destination directory was in the module's hierarchy.
+
+ - Fixed a bug where a deferred info/error/log message could get sent
+ directly to the sender instead of being handled by rwrite() in the
+ generator. This fixes an "unexpected tag 3" fatal error, and should
+ also fix a potential problem where a deferred info/error message from
+ the receiver might bypass the log file and get sent only to the client
+ process. (These problems could only affect an rsync daemon that was
+ receiving files.)
+
+ - Fixed a bug when --inplace was combined with a --*-dest option and we
+ update a file's data using an alternate basis file. The code now
+ notices that it needs to copy the matching data from the basis file
+ instead of (wrongly) assuming that it was already present in the file.
+
+ - Fixed a bug where using --dry-run with a --*-dest option with a path
+ relative to a directory that does not yet exist: the affected option
+ gets its proper path value so that the output of the dry-run is right.
+
+ - Fixed a bug in the %f logfile escape when receiving files: the
+ destination path is now included in the output (e.g. you can now tell
+ when a user specifies a subdir inside a module).
+
+ - If the receiving side fails to create a directory, it will now skip
+ trying to update everything that is inside that directory.
+
+ - If --link-dest is specified with --checksum but without --times, rsync
+ will now allow a hard-link to be created to a matching link-dest file
+ even when the file's modify-time doesn't match the server's file.
+
+ - The daemon now calls more timezone-using functions prior to doing a
+ chroot. This should help some C libraries to generate proper timestamps
+ from inside a chrooted daemon (and to not try to access /etc/timezone
+ over and over again).
+
+ - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
+ it now deletes an alternate basis file from the partial-dir that was used
+ to successfully update a destination file.
+
+ - Fixed a bug in the handling of --delete-excluded when using a per-dir
+ merge file: the merge file is now honored on the receiving side, and
+ only its unqualified include/exclude commands are ignored (just as is
+ done for global include/excludes).
+
+ - Fixed a recent bug where --delete was not working when transferring from
+ the root (/) of the filesystem with --relative enabled.
+
+ - Fixed a recent bug where an --exclude='*' could affect the root (/) of
+ the filesystem with --relative enabled.
+
+ - When --inplace creates a file, it is now created with owner read/write
+ permissions (0600) instead of no permissions at all. This avoids a
+ problem continuing a transfer that was interrupted (since --inplace
+ will not update a file that has no write permissions).
+
+ - If either --remove-source-files or --remove-sent-files is enabled and we
+ are unable to remove the source file, rsync now outputs an error.
+
+ - Fixed a bug in the daemon's "incoming chmod" rule: newly-created
+ directories no longer get the 'F' (file) rules applied to them.
+
+ - Fixed an infinite loop bug when a filter rule was rejected due to being
+ overly long.
+
+ - When the server receives a --partial-dir option from the client, it no
+ longer runs the client-side code that adds an assumed filter rule (since
+ the client will be sending us the rules in the usual manner, and they
+ may have chosen to override the auto-added rule).
+
+ ENHANCEMENTS:
+
+ - Added the --log-file=FILE and --log-file-format=FORMAT options. These
+ can be used to tell any rsync to output what it is doing to a log file.
+ They work with a client rsync, a non-daemon server rsync (see the man
+ page for instructions), and also allows the overriding of rsyncd.conf
+ settings when starting a daemon.
+
+ - The --log-format option was renamed to be --out-format to avoid confusing
+ it with affecting the log-file output. (The old option remains as an
+ alias for the new to preserve backward compatibility.)
+
+ - Made "log file" and "syslog facility" settable on a per-module basis in
+ the daemon's config file.
+
+ - Added the --remove-source-files option as a replacement for the (now
+ deprecated) --remove-sent-files option. This new option removes all
+ non-dirs from the source directories, even if the file was already
+ up-to-date. This fixes a problem where interrupting an rsync that
+ was using --remove-sent-files and restarting it could leave behind
+ a file that the earlier rsync synchronized, but didn't get to remove.
+ (The deprecated --remove-sent-files is still understood for now, and
+ still behaves in the same way as before.)
+
+ - Added the option --no-motd to suppress the message-of-the-day output
+ from a daemon when doing a copy. (See the manpage for a caveat.)
+
+ - Added a new environment variable to the pre-/post-xfer exec commands (in
+ the daemon's config file): RSYNC_PID. This value will be the same in
+ both the pre- and post-xfer commands, so it can be used as a unique ID
+ if the pre-xfer command wants to cache some arg/request info for the
+ post-xfer command.
+
+ INTERNAL:
+
+ - Did a code audit using IBM's code-checker program and made several
+ changes, including: replacing most of the strcpy() and sprintf()
+ calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
+ an enum that had been intermingling a literal 0 with the defined enum
+ values, silencing some uninitialized memory checks, marking some
+ functions with a "noreturn" attribute, and changing an "if" that
+ could never succeed on some platforms into a pre-processor directive
+ that conditionally compiles the code.
+
+ - Fixed a potential bug in f_name_cmp() when both the args are a
+ top-level "." dir (which doesn't happen in normal operations).
+
+ - Changed exit_cleanup() so that it can never return instead of exit.
+ The old code might return if it found the exit_cleanup() function
+ was being called recursively. The new code is segmented so that
+ any recursive calls move on to the next step of the exit-processing.
+
+ - The macro WIFEXITED(stat) will now be defined if the OS didn't already
+ define it.
+
+ DEVELOPER RELATED:
+
+ - The acls.diff and xattrs.diff patches have received a bunch of work to
+ make them much closer to being acceptable in the main distribution.
+ The xattrs patch also has some preliminary Mac OS X and FreeBSD
+ compatibility code that various system types to exchange extended
+ file-attributes.
+
+ - A new diff in the patches dir, fake-root.diff, allows rsync to
+ maintain a backup hierarchy with full owner, group, and device info
+ without actually running as root. It does this using a special
+ extended attribute, so it depends on xattrs.diff (which depends on
+ acls.diff).
+
+ - The rsync.yo and rsyncd.conf.yo files have been updated to work
+ better with the latest yodl 2.x releases.
+
+ - Updated config.guess and config.sub to their 2006-07-02 versions.
+
+ - Updated various files to include the latest FSF address and to have
+ consistent opening comments.

+NEWS for rsync 2.6.8 (22 Apr 2006)
+Protocol: 29 (unchanged)
+Changes since 2.6.7:
+
+ BUG FIXES:
+
+ - Fixed a bug in the exclude code where an anchored exclude without any
+ wildcards fails to match an absolute source arg, but only when --relative
+ is in effect.
+
+ - Improved the I/O code for the generator to fix a potential hang when the
+ receiver gets an EOF on the socket but the generator's select() call
+ never indicates that the socket is writable for it to be notified about
+ the EOF. (This can happen when using stunnel).
+
+ - Fixed a problem with the file-reading code where a failed read (such as
+ that caused by a bad sector) would not advance the file's read-position
+ beyond the failed read's data.
+
+ - Fixed a logging bug where the "log file" directive was not being honored
+ in a single-use daemon (one spawned by a remote-shell connection or by
+ init).
+
+ - If rsync cannot honor the --delete option, we output an error and exit
+ instead of silently ignoring the option.
+
+ - Fixed a bug in the --link-dest code that prevented special files (such as
+ fifos) from being linked.
+
+ - The ability to hard-link symlinks and special files is now determined at
+ configure time instead of at runtime. This fixes a bug with --link-dest
+ creating a hard-link to a symlink's referent on a BSD system.
+
+ ENHANCEMENTS:
+
+ - In daemon mode, if rsync fails to bind to the requested port, the
+ error(s) returned by socket() and/or bind() are now logged.
+
+ - When we output a fatal error, we now output the version of rsync in the
+ message.
+
+ - Improved the documentation for the --owner and --group options.
+
+ - The rsyncstats script in "support" has an improved line-parsing regex
+ that is easier to read and also makes it to parse syslog-generated lines.
+
+ - A new script in "support": file-attr-restore, can be used to restore the
+ attributes of a file-set (the permissions, ownership, and group info)
+ taken from the cached output of a "find ARG... -ls" command.
+
+ DEVELOPER RELATED:
+
+ - Removed the unused function write_int_named(), the unused variable
+ io_read_phase, and the rarely used variable io_write_phase. This also
+ elides the confusing 'phase "unknown"' part of one error message.
+
+ - Removed two unused configure checks and two related (also unused)
+ compatibility functions.
+
+ - The xattrs.diff patch received a security fix that prevents a potential
+ buffer overflow in the receive_xattr() code.
+
+ - The acls.diff patch has been improved quite a bit, with more to come.
+
+ - A new patch was added: log-file.diff. This contains an early version of
+ a future option, --log-file=FILE, that will allow any rsync to log its
+ actions to a file (something that only a daemon supports at present).
+
+\f
+NEWS for rsync 2.6.7 (11 Mar 2006)
+Protocol: 29 (unchanged)
+Changes since 2.6.6:
+
+ OUTPUT CHANGES:
+
+ - The letter 'D' in the itemized output was being used for both devices
+ (character or block) as well as other special files (such as fifos and
+ named sockets). This has changed to separate non-device special files
+ under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the
+ "--specials" option, below.
+
+ - 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.
+
+ BUG FIXES:
+
+ - Fixed a really old bug that caused --checksum (-c) to checksum all the
+ files encountered during the delete scan (ouch).
+
+ - 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).
+
+ - 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).
+
+ - If a device-file/special-file changes permissions, rsync now updates the
+ permissions without recreating the file.
+
+ - 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.
+
+ - 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.
+
+ - Reject the combination of --inplace and --sparse since the sparse-output
+ algorithm doesn't work when overwriting existing data.
+
+ - Fixed the directory name in the error that is output when pop_dir()
+ fails.
+
+ - Really fixed the parsing of a "!" entry in .cvsignore files this time.
+
+ - 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).
+
+ - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
+ the exit status properly and generate a better error.
+
+ - Fixed some glitches in the double-verbose output when using --copy-dest,
+ --link-dest, or --compare-dest. Also improved how the verbose output
+ handles hard-links (within the transfer) that had an up-to-date alternate
+ "dest" file, and copied files (via --copy-dest).
+
+ - Fixed the matching of the dont-compress items (e.g. *.gz) against files
+ that have a path component containing a slash.
+
+ - If the code reading a filter/exclude file gets an EINTR error, rsync now
+ clears the error flag on the file handle so it can keep on reading.
+
+ - 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.
+
+ - When --list-only is used and a non-existent local destination dir was
+ also specified as a destination, rsync no longer generates a warning
+ about being unable to create the missing directory.
+
+ - Fixed some problems with --relative --no-implied-dirs when the
+ destination directory did not yet exist: we can now create a symlink or
+ device when it is the first thing in the missing dir, and --fuzzy no
+ longer complains about being unable to open the missing dir.
+
+ - Fixed a bug where the --copy-links option would not affect implied
+ directories without --copy-unsafe-links (see --relative).
+
+ - Got rid of the need for --force to be used in some circumstances with
+ --delete-after (making it consistent with --delete-before/-during).
+
+ - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
+ when a file is too large (rsync handles the write error).
+
+ - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
+ was not properly padded with trailing '=' chars. This only affects a
+ user that need to use a password-authenticated proxy for an outgoing
+ daemon-rsync connection.
+
+ - If we're transferring an empty directory to a new name, rsync no longer
+ forces S_IWUSR if it wasn't already set, nor does it accidentally leave
+ it set.
+
+ - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
+ checksum for the current file offset.
+
+ - Rsync no longer allows a single directory to be copied over a non-
+ directory destination arg.
+
+ ENHANCEMENTS:
+
+ - 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. (The old
+ meaning of -h, as a shorthand for --help, still works as long as you
+ just use it on its own, as in "rsync -h".)
+
+ - 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).
+
+ - 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 man page 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.
+
+ - 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 --specials option to tell rsync to copy non-device special
+ files (which rsync now attempts even as a normal user). The --devices
+ option now requests the copying of just devices (character and block).
+ The -D option still requests both (e.g. --devices and --specials), -a
+ still implies -D, and non-root users still get a silent downgrade that
+ omits device copying.
+
+ - 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 connection and also each module-list request
+ that it receives.
+
+ - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
+ (permission bits, e.g. "rwxr-xrwt").
+
+ - The --dry-run option no longer forces the enabling of --verbose.
+
+ - The --remove-sent-files option now does a better job of incrementally
+ removing the sent files on the sending side (older versions tended to
+ clump up all the removals at the end).
+
+ - A daemon now supersedes its minimal SIGCHLD handler with the standard
+ PID-remembering version after forking. This ensures that the generator
+ can get the child-exit status from the receiver.
+
+ - Use of the --bwlimit option no longer interferes with the remote rsync
+ sending error messages about invalid/refused options.
+
+ - Rsync no longer returns a usage error when used with one local source arg
+ and no destination: this now implies the --list-only option, just like
+ the comparable situation with a remote source arg.
+
+ - Added the --copy-dirlinks option, a more limited version of --copy-links.
+
+ - Various documentation improvements, including: a better synopsis, some
+ improved examples, a better discussion of the presence and absence of
+ --perms (including how it interacts with the new --executability and
+ --chmod options), an extended discussion of --temp-dir, an improved
+ discussion of --partial-dir, a better description of rsync's pattern
+ matching characters, an improved --no-implied-dirs section, and the
+ documenting of what the --stats option outputs.
+
+ - Various new and updated diffs in the patches dir, including: acls.diff,
+ xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
+
+ INTERNAL:
+
+ - 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.
+
+ - Some buffer sizes were expanded a bit, particularly on systems where
+ MAXPATHLEN is overly small (e.g. cygwin).
+
+ - If io_printf() tries to format more data than fits in the buffer, exit
+ with an error instead of transmitting a truncated buffer.
+
+ - If a va_copy macro is defined, lib/snprintf.c will use it when defining
+ the VA_COPY macro.
+
+ - Reduced the amount of stack memory needed for each level of directory
+ recursion by nearly MAXPATHLEN bytes.
+
+ - 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.
+
+ - 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.
+
+ - Unified the f_name() and the f_name_to() functions.
+
+ - Improved the hash-table code the sender uses to handle checksums to make
+ it use slightly less memory and run just a little faster.
+
+ 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.
+
+ - 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).
+
+ - The testsuite now sets HOME so that it won't be affected by a file such
+ as ~/.popt.

+\f
+NEWS for rsync 2.6.6 (28 Jul 2005)
+Protocol: 29 (unchanged)
+Changes since 2.6.5:
+
+ SECURITY FIXES:
+
+ - The zlib code was upgraded to version 1.2.3 in order to make it more
+ secure. While the widely-publicized security problem in zlib 1.2.2 did
+ not affect rsync, another security problem surfaced that affects rsync's
+ zlib 1.1.4.
+
+ BUG FIXES:
+
+ - 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 outputting of hard-linked files when verbosity was > 1 was not right:
+ (1) 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. (2) 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.
+
+ - 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.
+
+ - A couple places that were comparing a local and a remote modification-
+ time were not honoring the --modify-window option.
+
+ - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
+ set too often (if some non-significant mode bits differed).
+
+ - 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).
+
+ ENHANCEMENTS:
+
+ - Made the "max verbosity" setting in the rsyncd.conf file settable on a
+ per-module basis (which now matches the documentation).
+
+ - The support/rrsync script has been upgraded to verify the args of options
+ that take args (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.
+
+ - Improved the documentation that explains the difference between a
+ normal daemon transfer and a daemon-over remote-shell transfer.
+
+ - Some of the diffs supplied in the patches dir were fixed and/or
+ improved.
+
+ BUILD CHANGES:
+
+ - 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.

+NEWS for rsync 2.6.5 (1 Jun 2005)
+Protocol: 29 (unchanged)
+Changes since 2.6.4:
+
+ OUTPUT CHANGES:
+
+ - Non-printable chars in filenames are now output using backslash-
+ escaped characters rather than '?'s. Any non-printable character is
+ output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
+ is now output as "\\". Rsync also uses your locale setting, which
+ can make it treat fewer high-bit characters as non-printable.
+
+ - If rsync received an empty file-list when pulling files, it would
+ output a "nothing to do" message and exit with a 0 (success) exit
+ status, even if the remote rsync returned an error (it did not do
+ this under the same conditions when pushing files). This was changed
+ to make the pulling behavior the same as the pushing behavior: we
+ now do the normal end-of-run outputting (depending on options) and
+ exit with the appropriate exit status.
+
+ BUG FIXES:
+
+ - A crash bug was fixed when a daemon had its "path" set to "/", did
+ not have chroot enabled, and used some anchored excludes in the
+ rsyncd.conf file.
+
+ - Fixed a bug in the transfer of a single file when -H is specified
+ (rsync would either infinite loop or perhaps crash).
+
+ - Fixed a case where the generator might try (and fail) to tweak the
+ write-permissions of a read-only directory in list-only mode (this
+ only caused an annoying warning message).
+
+ - If --compare-dest or --link-dest uses a locally-copied file as the
+ basis for an updated version, log this better when --verbose or -i
+ is in effect.
+
+ - Fixed the accidental disabling of --backup during the --delete-after
+ processing.
+
+ - Restored the ability to use the --address option in client mode (in
+ addition to its use in daemon mode).
+
+ - Make sure that some temporary progress information from the delete
+ processing does not get left on the screen when it is followed by a
+ newline.
+
+ - When --existing skips a directory with extra verbosity, refer to it
+ as a "directory", not a "file".
+
+ - When transferring a single file to a different-named file, any
+ generator messages that are source-file related no longer refer to
+ the file by the destination filename.
+
+ - Fixed a bug where hard-linking a group of files might fail if the
+ generator hasn't created a needed destination directory yet.
+
+ - Fixed a bug where a hard-linked group of files that is newly-linked
+ to a file in a --link-dest dir doesn't link the files from the rest
+ of the cluster.
+
+ - When deleting files with the --one-file-system (-x) option set, rsync
+ no longer tries to remove files from inside a mount-point on the
+ receiving side. Also, we don't complain about being unable to remove
+ the mount-point dir.
+
+ - Fixed a compatibility problem when using --cvs-ignore (-C) and
+ sending files to an older rsync without using --delete.
+
+ - Make sure that a "- !" or "+ !" include/exclude pattern does not
+ trigger the list-clearing action that is reserved for "!".
+
+ - Avoid a timeout in the generator when the sender/receiver aren't
+ handling the generator's checksum output quickly enough.
+
+ - Fixed the omission of some directories in the delete processing when
+ --relative (-R) was combined with a source path that had a trailing
+ slash.
+
+ - Fixed a case where rsync would erroneously delete some files and then
+ re-transfer them when the options --relative (-R) and --recursive
+ (-r) were both enabled (along with --delete) and a source path had a
+ trailing slash.
+
+ - Make sure that --max-size doesn't affect a device or a symlink.
+
+ - Make sure that a system with a really small MAXPATHLEN does not cause
+ the buffers in readfd_unbuffered() to be too small to receive normal
+ messages. (This mainly affected Cygwin.)
+
+ - If a source pathname ends with a filename of "..", treat it as if
+ "../" had been specified (so that we don't copy files to the parent
+ dir of the destination).
+
+ - If --delete is combined with a file-listing rsync command (i.e. no
+ transfer is happening), avoid outputting a warning that we couldn't
+ delete anything.
+
+ - If --stats is specified with --delete-after, ensure that all the
+ "deleting" messages are output before the statistics.
+
+ - Improved one "if" in the deletion code that was only checking errno
+ for ENOTEMPTY when it should have also been checking for EEXIST (for
+ compatibility with OS variations).
+
+ ENHANCEMENTS:
+
+ - Added the --only-write-batch=FILE option that may be used (instead
+ of --write-batch=FILE) to create a batch file without doing any
+ actual updating of the destination. This allows you to divert all
+ the file-updating data away from a slow data link (as long as you
+ are pushing the data to the remote server when creating the batch).
+
+ - When the generator is taking a long time to fill up its output buffer
+ (e.g. if the transferred files are few, small, or missing), it now
+ periodically flushes the output buffer so that the sender/receiver
+ can get started on the files sooner rather than later.
+
+ - Improved the keep-alive code to handle a long silence between the
+ sender and the receiver that can occur when the sender is receiving
+ the checksum data for a large file.
+
+ - Improved the auth-errors that are logged by the daemon to include
+ some information on why the authorization failed: wrong user,
+ password mismatch, etc. (The client-visible message is unchanged!)
+
+ - Improved the client's handling of an "@ERROR" from a daemon so that
+ it does not complain about an unexpectedly closed socket (since we
+ really did expect the socket to close).
+
+ - If the daemon can't open the log-file specified in rsyncd.conf, fall
+ back to using syslog and log an appropriate warning. This is better
+ than what was typically a totally silent (and fatal) failure (since a
+ daemon is not usually run with the --no-detach option that was
+ necessary to see the error on stderr).
+
+ - The man pages now consistently refer to an rsync daemon as a "daemon"
+ instead of a "server" (to distinguish it from the server process in a
+ non-daemon transfer).
+
+ - Made a small change to the rrsync script (restricted rsync -- in the
+ support dir) to make a read-only server reject all --remove-* options
+ when sending files (to future-proof it against the possibility of
+ other similar options being added at some point).
+
+ INTERNAL:
+
+ - Rsync now calls setlocale(LC_CTYPE, ""). This enables isprint() to
+ better discern which filename characters need to be escaped in
+ messages (which should result in fewer escaped characters in some
+ locales).
+
+ - Improved the naming of the log-file open/reopen/close functions.
+
+ - Removed some protocol-compatibility code that was only needed to help
+ someone running a pre-release of 2.6.4.
+
+ BUILD CHANGES:
+
+ - Added configure option "--disable-locale" to disable any use of
+ setlocale() in the binary.
+
+ - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
+ rsync from being built without symlink or hard-link support.
+
+ - Only #define HAVE_REMSH if it is going to be set to 1.
+
+ - Configure now disables the use of mkstemp() under HP-UX (since they
+ refuse to fix its broken handling of large files).
+
+ - Configure now explicitly checks for the lseek64() function so that
+ the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
+ presence based on the presence of the off64_t type.
+
+ - Configure no longer mentions the change in the default remote-shell
+ (from rsh to ssh) that occurred for the 2.6.0 release.
+
+ - Some minor enhancements to the test scripts.
+
+ - Added a few new *.diff files to the patches dir, including a patch
+ that enables the optional copying of extended attributes.
+
+\f
+NEWS for rsync 2.6.4 (30 March 2005)
+Protocol: 29 (changed)
+Changes since 2.6.3:
+
+ OUTPUT CHANGES:
+
+ - When rsync deletes a directory and outputs a verbose message about
+ it, it now appends a trailing slash to the name instead of (only
+ sometimes) outputting a preceding "directory " string.
+
+ - 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.)
+
+ - The "%o" (operation) log-format escape now has a third value (besides
+ "send" and "recv"): "del." (with trailing dot to make it 4 chars).
+ This changes the way deletions are logged in the daemon's log file.
+
+ - When the --log-format option is combined with --verbose, rsync now
+ avoids outputting the name of the file twice in most circumstances.
+ As long as the --log-format item does not refer to any post-transfer
+ items (such as %b or %c), the --log-format message is output prior to
+ the transfer, so --verbose is now the equivalent of a --log-format of
+ '%n%L' (which outputs the name and any link info). If the log output
+ must occur after the transfer to be complete, the only time the name
+ is also output prior to the transfer is when --progress was specified
+ (so that the name will precede the progress stats, and the full
+ --log-format output will come after).
+
+ - Non-printable characters in filenames are replaced with a '?' to
+ avoid corrupting the screen or generating empty lines in the output.
+
+ 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 combination of --verbose and --dry-run now mentions the full list
+ of changes that would be output without --dry-run.
+
+ - Avoid a mkdir warning when removing a directory in the destination
+ that already exists in the --backup-dir.
+
+ - An OS that has a binary mode for its files (such as cygwin) needed
+ setmode(fd, O_BINARY) called on the temp-file we opened with
+ mkstemp(). (Fix derived from cygwin's 2.6.3 rsync package.)
+
+ - Fixed a potential hang when verbosity is high, the client side is
+ the sender, and the file-list is large.
+
+ - Fixed a potential protocol-corrupting bug where the generator could
+ merge a message from the receiver into the middle of a multiplexed
+ packet of data if only part of that data had been written out to the
+ socket when the message from the generator arrived.
+
+ - We now check if the OS doesn't support using mknod() for creating
+ FIFOs and sockets, and compile-in some compatibility code using
+ mkfifo() and socket() when necessary.
+
+ - Fixed an off-by-one error in the handling of --max-delete=N. Also,
+ if the --max-delete limit is exceeded during a run, we now output a
+ warning about this at the end of the run and exit with a new error
+ code (25).
+
+ - One place in the code wasn't checking if fork() failed.
+
+ - The "ignore nonreadable" daemon parameter used to erroneously affect
+ readable symlinks that pointed to a non-existent file.
+
+ - If the OS does not have lchown() and a chown() of a symlink will
+ affect 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.
+
+ - If a file gets resent in a single transfer and the --backup option is
+ enabled along with --inplace, rsync no longer performs a duplicate
+ backup (it used to overwrite the first backup with the failed file).
+
+ - 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 (e.g. rsync might have
+ exited with an error for large files).
+
+ - Fixed a bug that would sometimes surface when using --compress and
+ sending a file with a block-size larger than 64K (either manually
+ specified, or computed due to the file being really large). Prior
+ versions of rsync would sometimes fail to decompress the data
+ properly, and thus the transferred file would fail its verification.
+
+ - 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) and exit with a new error code (6).
+
+ - 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).
+
+ - The output of the items that are being updated by the generator (dirs,
+ symlinks, devices) is now intermingled in the proper order with the
+ output from the items that the receiver is updating (regular files)
+ when pulling. This misordering was particularly bad when --progress
+ was specified. (Requires protocol 29.)
+
+ - When --timeout is specified, lulls that occur in the transfer while
+ the generator is doing work that does not generate socket traffic
+ (looking for changed files, deleting files, doing directory-time
+ touch-ups, etc.) will cause a new keep-alive packet to be sent that
+ should keep the transfer going as long as the generator continues to
+ make progress. (Requires protocol 29.)
+
+ - The stat size of a device is not added to the total file size of the
+ items in the transfer (the size might be undefined on some OSes).
+
+ - Fixed a problem with refused-option messages sometimes not making it
+ back to the client side when a remote --files-from was in effect and
+ the daemon was the receiver.
+
+ - The --compare-dest option was not updating a file that differed in
+ (the preserved) attributes from the version in the compare-dest DIR.
+
+ - When rsync is copying files into a write-protected directory, fixed
+ the change-report output for the directory so that we don't report
+ an identical directory as changed.
+
+ 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 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 also available as
+ --delete-before (and is still 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 (including the new --remove-sent-files option).
+
+ - All the --delete-WHEN options are now more memory efficient:
+ Previously an 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 (for files
+ inside the transfer).
+
+ - Added the --copy-dest option, which works like --link-dest except
+ that it locally copies identical files instead of hard-linking them.
+
+ - 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.) (Requires protocol 29.)
+
+ - Added the --max-size option. (Promoted from the patches dir.)
+
+ - The daemon-mode options are now separated from the normal rsync
+ options so that they can't be mixed together. This makes it
+ impossible to start a daemon that has improper default option values
+ (which could cause problems when a client connects, such as hanging
+ or crashing).
+
+ - 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". The command-line options
+ 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. Any directories that are encountered are created
+ on the destination. Specifying a directory with a trailing slash
+ copies its immediate contents to the destination.
+
+ - The --files-from option now implies --dirs (-d).
+
+ - 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 may provide
+ 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.
+
+ - 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 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 and in what way. The effect
+ is the same as specifying a --log-format of "%i %n%L" (see both the
+ rsync and rsyncd.conf manpages). Works with --dry-run too.
+
+ - Added the --fuzzy (-y) 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.) (Requires protocol 29.)
+
+ - Added the --remove-sent-files option, which lets you move files
+ between systems.
+
+ - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
+ enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
+ literals in the rsync://HOST:PORT/PATH format.)
+
+ - When rsync recurses to build the file list, it no longer keeps open
+ one or more directory handles from the dir's parent dirs.
+
+ - When building under windows, the default for --daemon is now to
+ avoid detaching, requiring the new --detach option to force rsync
+ to detach.
+
+ - The --dry-run option can now be combined with either --write-batch or
+ --read-batch, allowing you to run a do-nothing test command to see
+ what would happen without --dry-run.
+
+ - 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.
+
+ - The log-format % escapes can now have a numeric field width in
+ between the % and the escape letter (e.g. "%-40n %08p").
+
+ - 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) and provides one way to debug a protocol error.
+
+ - Added rrsync to the support dir: this is an updated 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.
+
+ 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 (instead of producing a message),
+ which makes the outputting of the information more consistent and
+ less prone to screen corruption (because the local receiver/sender is
+ now outputting all the file-change info messages).
+
+ - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
+ in the flag-word and the name of the file that was linked immediately
+ follows in vstring format (see below).
+
+ - If a file is being transferred with an alternate-basis file, the
+ ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
+ byte follows, indicating what type of basis file was chosen. If that
+ indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
+ is set in the flag-word and the name of the match in vstring format
+ follows the basis byte. A vstring is a variable length string that
+ has its size written prior to the string, and no terminating null.
+ If the string is from 1-127 bytes, the length is a single byte. If
+ it is from 128-32767 bytes, the length is written as ((len >> 8) |
+ 0x80) followed by (len % 0x100).
+
+ - 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 included in the options.
+
+ - 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 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
+ that is sent in this scenario is often empty.
+
+ - An index equal to the file-list count is sent as a keep-alive packet
+ from the generator to the sender, which then forwards it on to the
+ receiver. This normally invalid index is only a valid keep-alive
+ packet if the 16-bit flag-word that follows it contains a single bit
+ (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
+
+ - A protocol-29 batch file includes a bit for the setting of the --dirs
+ option and for the setting of the --compress option. Also, the shell
+ script created by --write-batch will use the --filter option instead
+ of --exclude-from to capture any filter rules.
+
+ BUILD CHANGES:
+
+ - Handle an operating system that use mkdev() in place of makedev().
+
+ - Improved configure to better handle cross-compiling.

+NEWS for rsync 2.6.3 (30 Sep 2004)
+Protocol: 28 (unchanged)
+Changes since 2.6.2:
+
+ SECURITY FIXES:
+
+ - A bug in the sanitize_path routine (which affects a non-chrooted
+ rsync daemon) could allow a user to craft a pathname that would get
+ transformed into an absolute path for certain options (but not for
+ file-transfer names). If you're running an rsync daemon with chroot
+ disabled, *please upgrade*, ESPECIALLY if the user privs you run
+ rsync under is anything above "nobody".
+
+ OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
+
+ - Please note that the 2-line footer (output when verbose) now uses the
+ term "sent" instead of "wrote" and "received" instead of "read". If
+ you are not parsing the numeric values out of this footer, a script
+ would be better off using the empty line prior to the footer as the
+ indicator that the verbose output is over.
+
+ - The output from the --stats option was similarly affected to change
+ "written" to "sent" and "read" to "received".
+
+ - Rsync ensures that a filename that contains a newline gets mentioned
+ with each newline transformed into a question mark (which prevents a
+ filename from causing an empty line to be output).
+
+ - The "backed up ..." message that is output when at least 2 --verbose
+ options are specified is now the same both with and without the
+ --backup-dir option.
+
+ BUG FIXES:
+
+ - Fixed a crash bug that might appear when --delete was used and
+ multiple source directories were specified.
+
+ - Fixed a 32-bit truncation of the file length when generating the
+ checksums.
+
+ - The --backup code no longer attempts to create some directories
+ over and over again (generating warnings along the way).
+
+ - 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 a file has a read error on the sending side or the reconstructed
+ data doesn't match the expected checksum (perhaps due to the basis
+ file changing during the transfer), the receiver will no longer
+ retain the resulting file unless the --partial option was specified.
+ (Note: for the read-error detection to work, neither side can be
+ older than 2.6.3 -- older receivers will always retain the file, and
+ older senders don't tell the receiver that the file had a read
+ error.)
+
+ - If a file gets resent in a single transfer and the --backup option
+ is enabled, rsync no longer performs a duplicate backup (it used to
+ overwrite the original file in the backup area).
+
+ - 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.
+
+ - Got rid of a potential hang in the receiver when near the end of a
+ phase.
+
+ - When using --backup without a --backup-dir, rsync no longer preserves
+ the modify time on directories. This avoids confusing NFS.
+
+ - 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".
+
+ - The --copy-links (-L) option no longer has the side-effect of telling
+ the receiving side to follow symlinks. See the --keep-dirlinks
+ option (mentioned below) for a way to specify that behavior.
+
+ - Error messages from the daemon server's option-parsing (such as
+ refused options) are now successfully transferred back to the client
+ (the server used to fail to send the message because the socket
+ wasn't in the right state for the message to get through).
+
+ - Most transfer 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 and are not affected by this).
+
+ - Fixed a bug in the daemon authentication code when using one of the
+ batch-processing options.
+
+ - We try to work around some buggy IPv6 implementations that fail to
+ implement IPV6_V6ONLY. This should fix the "address in use" error
+ that some daemons get when running on an OS with a buggy IPv6
+ implementation. Also, if the new code gets this error, we might
+ suggest that the user specify --ipv4 or --ipv6 (if we think it will
+ help).
+
+ - When the remote rsync dies, make a better effort to recover any error
+ messages it may have sent before dying (the local rsync used to just
+ die with a socket-write error).
+
+ - When using --delete and a --backup-dir that contains files that are
+ hard-linked to their destination equivalents, rsync now makes sure
+ that removed files really get removed (avoids a really weird rename()
+ behavior).
+
+ - Avoid a bogus run-time complaint about a lack of 64-bit integers when
+ the int64 type is defined as an off_t and it actually has 64-bits.
+
+ - Added a configure check for open64() without mkstemp64() so that we
+ can avoid using mkstemp() when such a combination is encountered.
+ This bypasses a problem writing out large temp files on OSes such as
+ AIX and HP-UX.
+
+ - Fixed an age-old crash problem with --read-batch on a local copy
+ (rsync was improperly assuming --whole-file for the local copy).
+
+ - When --dry-run (-n) is used and the destination directory does not
+ exist, rsync now produces a correct report of files that would be
+ sent instead of dying with a chdir() error.
+
+ - Fixed a bug that could cause a slow-to-connect rsync daemon to die
+ with an error instead of waiting for the connection to finish.
+
+ - Fixed an ssh interaction that could cause output to be lost when the
+ user chose to combine the output of rsync's stdout and stderr (e.g.
+ using the "2>&1").
+
+ - Fixed an option-parsing bug when --files-from got passed to a daemon.
+
+ ENHANCEMENTS:
+
+ - Added the --partial-dir=DIR option that lets you specify where to
+ (temporarily) put a partially transferred file (instead of over-
+ writing the destination file). E.g. --partial-dir=.rsync-partial
+ Also added support for the RSYNC_PARTIAL_DIR environment variable
+ that, when found, transforms a regular --partial option (such as
+ the convenient -P option) into one that also specifies a directory.
+
+ - Added --keep-dirlinks (-K), which allows you to symlink a directory
+ onto another partition on the receiving side and have rsync treat it
+ as matching a normal directory from the sender.
+
+ - Added the --inplace option that tells rsync to write each destination
+ file without using a temporary file. The matching of existing data
+ in the destination file can be severely limited by this, but there
+ are also cases where this is more efficient (such as appending data).
+ Use only when needed (see the man page for more details).
+
+ - Added the "write only" option for the daemon's config file.
+
+ - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
+ and documented all these options in the man page.
+
+ - Improved the handling of the --bwlimit option so that it's less
+ bursty, more accurate, and works properly over a larger range of
+ values.
+
+ - 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 --checksum-seed=N option for advanced users.
+
+ - Batch writing/reading has a brand-new implementation that is simpler,
+ fixes a few weird problems with the old code (such as no longer
+ sprinkling the batch files into different dirs or even onto different
+ systems), and is much less intrusive into the code (making it easier
+ to maintain for the future). The new code generates just one data
+ file instead of three, which makes it possible to read the batch on
+ stdin via a remote shell. Also, the old requirement of forcing the
+ same fixed checksum-seed for all batch processing has been removed.
+
+ - If an rsync daemon has a module set with "list = no" (which hides its
+ presence in the list of available modules), a user that fails to
+ authenticate gets the same "unknown module" error that they would get
+ if the module were actually unknown (while still logging the real
+ error to the daemon's log file). This prevents fishing for module
+ names.
+
+ - The daemon's "refuse options" config item now allows you to match
+ option names using wildcards and/or the single-letter option names.
+
+ - Each transferred file now gets its permissions and modified-time
+ updated before the temp-file gets moved into place. Previously, the
+ finished file would have a very brief window where its permissions
+ disallowed all group and world access.
+
+ - Added the ability to parse a literal IPv6 address in an "rsync:" URL
+ (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
+
+ - The daemon's wildcard expanding code can now handle more than 1000
+ filenames (it's now limited by memory instead of having a hard-wired
+ limit).
+
+ INTERNAL:
+
+ - Some cleanup in the exclude code has saved some per-exclude memory
+ and made the code easier to maintain.
+
+ - Improved the argv-overflow checking for a remote command that has a
+ lot of args.
+
+ - Use rsyserr() in the various places that were still calling rprintf()
+ with strerror() as an arg.
+
+ - 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 connection (we used to close just one of
+ them).
+
+ - Optimized the handling of larger block sizes (rsync used to slow to a
+ crawl if the block size got too large).
+
+ - Optimized away a loop in hash_search().
+
+ - Some improvements to the sanitize_path() and clean_fname() functions
+ makes them more efficient and produce better results (while still
+ being compatible with the file-name cleaning that gets done on both
+ sides when sending the file-list).
+
+ - Got rid of alloc_sanitize_path() after adding a destination-buffer
+ arg to sanitize_path() made it possible to put all the former's
+ functionality into the latter.
+
+ - The file-list that is output when at least 4 verbose options are
+ specified reports the uid value on the sender even when rsync is
+ not running as root (since we might be sending to a root receiver).
+
+ BUILD CHANGES:
+
+ - Added a "gen" target to rebuild most of the generated files,
+ including configure, config.h.in, the man pages, and proto.h.
+
+ - If "make proto" doesn't find some changes in the prototypes, the
+ proto.h file is left untouched (its time-stamp used to always be
+ updated).
+
+ - The variable $STRIP (that is optionally set by the install-strip
+ target's rule) was changed to $INSTALL_STRIP because some systems
+ have $STRIP already set in the environment.
+
+ - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
+
+ - When cross-compiling, the gettimeofday() function is now assumed to
+ be a modern version that takes two-args (since we can't test it).
+
+ DEVELOPER RELATED:
+
+ - The scripts in the testsuite dir were cleaned up a bit and a few
+ new tests added.
+
+ - Some new diffs were added to the patches dir, and some accepted
+ ones were removed.

+NEWS for rsync 2.6.2 (30 Apr 2004)
+Protocol: 28 (unchanged)
+Changes since 2.6.1:
+
+ BUG FIXES:
+
+ - Fixed a major bug in the sorting of the filenames when --relative
+ is used for some sources (just sources such as "/" and "/*" were
+ affected). This fix ensures that we ask for the right file-list
+ item when requesting changes from the sender.
+
+ - Rsync now checks the return value of the close() function to
+ better report disk-full problems on an NFS file system.
+
+ - Restored the old daemon-server behavior of logging error messages
+ rather than returning them to the user. (A better long-term fix
+ will be sought in the future.)
+
+ - An obscure uninitialized-variable bug was fixed in the uid/gid
+ code. (This bug probably had no ill effects.)
+
+ BUILD CHANGES:
+
+ - Got rid of the configure check for sys/sysctl.h (it wasn't used
+ and was causing a problem on some systems). Also improved the
+ broken-largefile-locking test to try to avoid failure due to an
+ NFS build-dir.
+
+ - Fixed a compile problem on systems that don't define
+ AI_NUMERICHOST.
+
+ - Fixed a compile problem in the popt source for compilers that
+ don't support __attribute__.
+
+ DEVELOPER RELATED:

+\f
+NEWS for rsync 2.6.1 (26 Apr 2004)
+Protocol: 28 (changed)
+Changes since 2.6.0:
+
+ SECURITY FIXES:
+
+ - Paths sent to an rsync daemon are more thoroughly sanitized when
+ chroot is not used. If you're running a non-read-only rsync
+ daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
+ user privs you run rsync under is anything above "nobody".
+
+ ENHANCEMENTS:
+
+ - Lower memory use, more optimal transfer of data over the socket,
+ and lower CPU usage (see the INTERNAL section for details).
+
+ - The RSYNC_PROXY environment variable can now contain a
+ "USER:PASS@" prefix before the "HOST:PORT" information.
+ (Bardur Arantsson)
+
+ - The --progress output now mentions how far along in the transfer
+ we are, including both a count of files transferred and a
+ percentage of the total file-count that we've processed. It also
+ shows better current-rate-of-transfer and remaining-transfer-time
+ values.
+
+ - Documentation changes now attempt to describe some often mis-
+ understood features more clearly.
+
+ BUG FIXES:
+
+ - When -x (--one-file-system) is combined with -L (--copy-links) or
+ --copy-unsafe-links, no symlinked files are skipped, even if the
+ referent file is on a different filesystem.
+
+ - The --link-dest code now works properly for a non-root user when
+ (1) the UIDs of the source and destination differ and -o was
+ specified, or (2) when the group of the source can't be used on
+ the destination and -g was specified.
+
+ - Fixed a bug in the handling of -H (hard-links) that might cause
+ the expanded PATH/NAME value of the current item to get
+ overwritten (due to an expanded-name caching bug).
+
+ - We now reset the "new data has been sent" flag at the start of
+ each file we send. This makes sure that an interrupted transfer
+ with the --partial option set doesn't keep a shorter temp file
+ than the current basis file when no new data has been transferred
+ over the wire for that file.
+
+ - Fixed a byte-order problem in --batch-mode on big-endian machines.
+ (Jay Fenlason)
+
+ - When using --cvs-exclude, the exclude items we get from a
+ per-directory's .cvsignore file once again only affect that one
+ directory (not all following directories too). The items are also
+ now properly word-split and parsed without any +/- prefix parsing.
+
+ - When specifying the USER@HOST: prefix for a file, the USER part
+ can now contain an '@', if needed (i.e. the last '@' is used to
+ find the HOST, not the first).
+
+ - Fixed some bugs in the handling of group IDs for non-root users:
+ (1) It properly handles a group that the sender didn't have a name
+ for (it would previously skip changing the group on any files in
+ that group). (2) If --numeric-ids is used, rsync no longer
+ attempts to set groups that the user doesn't have the permission
+ to set.
+
+ - Fixed the "refuse options" setting in the rsyncd.conf file.
+
+ - Improved the -x (--one-file-system) flag's handling of any mount-
+ point directories we encounter. It is both more optimal (in that
+ it no longer does a useless scan of the contents of the mount-
+ point dirs) and also fixes a bug where a remapped mount of the
+ original filesystem could get discovered in a subdir we should be
+ ignoring.
+
+ - Rsync no longer discards a double-slash at the start of a filename
+ when trying to open the file. It also no longer constructs names
+ that start with a double slash (unless the user supplied them).
+
+ - Path-specifying options to a daemon should now work the same with
+ or without chroot turned on. Previously, such a option (such as
+ --link-dest) would get its absolute path munged into a relative
+ one if chroot was not on, making that setting fairly useless.
+ Rsync now transforms the path into one that is based on the
+ module's base dir when chroot is not enabled.
+
+ - Fixed a compatibility problem interacting with older rsync
+ versions that might send us an empty --suffix value without
+ telling us that --backup-dir was specified.
+
+ - The "hosts allow" option for a daemon-over-remote-shell process
+ now has improved support for IPv6 addresses and a fix for systems
+ that have a length field in their socket structs.
+
+ - Fixed the ability to request an empty backup --suffix when sending
+ files to an rsync daemon.
+
+ - Fixed an option-parsing bug when --files-from was sent to a server
+ sender.
+
+ INTERNAL:
+
+ - Most of the I/O is now buffered, which results in a pretty large
+ speedup when running under MS Windows. (Craig Barratt)
+
+ - Optimizations to the name-handling/comparing code have made some
+ significant reductions in user-CPU time for large file sets.
+
+ - Some cleanup of the variable types make the code more consistent.
+
+ - Reduced memory requirements of hard link preservation.
+ (J.W. Schultz)
+
+ - Implemented a new algorithm for hard-link handling that speeds up
+ the code significantly. (J.W. Schultz and Wayne Davison)
+
+ - The --hard-link option now uses the first existing file in the
+ group of linked files as the basis for the transfer. This
+ prevents the sub-optimal transfer of a file's data when a new
+ hardlink is added on the sending side and it sorts alphabetically
+ earlier in the list than the files that are already present on the
+ receiving side.
+
+ - Dropped support for protocol versions less than 20 (2.3.0 released
+ 15 Mar 1999) and activated warnings for protocols less than 25
+ (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
+ severally)
+
+ - More optimal data transmission for --hard-links (protocol 28).
+
+ - More optimal data transmission for --checksum (protocol 28).
+
+ - Less memory is used when --checksum is specified.
+
+ - Less memory is used in the file list (a per-file savings).
+
+ - The generator is now better about not modifying the file list
+ during the transfer in order to avoid a copy-on-write memory
+ bifurcation (on systems where fork() uses shared memory).
+ Previously, rsync's shared memory would slowly become unshared,
+ resulting in real memory usage nearly doubling on the receiving
+ side by the end of the transfer. Now, as long as permissions
+ are being preserved, the shared memory should remain that way
+ for the entire transfer.
+
+ - Changed hardlink info and file_struct + strings to use allocation
+ pools. This reduces memory use for large file-sets and permits
+ freeing memory to the OS. (J.W. Schultz)
+
+ - The 2 pipes used between the receiver and generator processes
+ (which are forked on the same machine) were reduced to 1 pipe and
+ the protocol improved so that (1) it is now impossible to have the
+ "redo" pipe fill up and hang rsync, and (2) trailing messages from
+ the receiver don't get lost on their way through the generator
+ over to the sender (which mainly affected hard-link messages and
+ verbose --stats output).
+
+ - Improved the internal uid/gid code to be more portable and a
+ little more optimized.
+
+ - The device numbers sent when using --devices are now sent as
+ separate major/minor values with 32-bit accuracy (protocol 28).
+ Previously, the copied devices were sent as a single 32-bit
+ number. This will make inter-operation of 64-bit binaries more
+ compatible with their 32-bit brethren (with both ends of the
+ connection are using protocol 28). Note that optimizations in the
+ binary protocol for sending the device numbers often results in
+ fewer bytes being used than before, even though more precision is
+ now available.
+
+ - Some cleanup of the exclude/include structures and its code made
+ things clearer (internally), simpler, and more efficient.
+
+ - The reading & writing of the file-list in batch-mode is now
+ handled by the same code that sends & receives the list over the
+ wire. This makes it much easier to maintain. (Note that the
+ batch code is still considered to be experimental.)
+
+ BUILD CHANGES:
+
+ - The configure script now accepts --with-rsyncd-conf=PATH to
+ override the default value of the /etc/rsyncd.conf file.
+
+ - Fixed configure bug when running "./configure --disable-ipv6".
+
+ - Fixed compilation problem on Tru64 Unix (having to do with
+ sockaddr.sa_len and sockaddr.sin_len).
+
+ DEVELOPER RELATED:
+
+ - Fixed "make test" bug when build dir is not the source dir.
+
+ - Added a couple extra diffs in the "patches" dir, removed the ones
+ that got applied, and rebuilt the rest.

+NEWS for rsync 2.6.0 (1 Jan 2004)
+Protocol: 27 (changed)
+Changes since 2.5.7:
+
+ ENHANCEMENTS:
+
+ * "ssh" is now the default remote shell for rsync. If you want to
+ change this, configure like this: "./configure --with-rsh=rsh".
+
+ * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
+ Note that --from0 affects the line-ending character for all the
+ files read by the --*-from options. (Wayne Davison)
+
+ * Length of csum2 is now per-file starting with protocol version
+ 27. (J.W. Schultz)
+
+ * Per-file dynamic block size is now sqrt(file length). The
+ per-file checksum size is determined according to an algorithm
+ provided by Donovan Baarda which reduces the probability of rsync
+ algorithm corrupting data and falling back using the whole md4
+ checksums. (J.W. Schultz, Donovan Baarda)
+
+ * The --stats option no longer includes the (debug) malloc summary
+ unless the verbose option was specified at least twice.
+
+ * Added a new error/warning code for when files vanish from the
+ sending side. Made vanished source files not interfere with the
+ file-deletion pass when --delete-after was specified.
+
+ * Various trailing-info sections are now preceded by a newline.
+
+ BUG FIXES:
+
+ * Fixed several exclude/include matching bugs when using wild-cards.
+ This has a several user-visible effects, all of which make the
+ matching more consistent and intuitive. This should hopefully not
+ cause anyone problems since it makes the matching work more like
+ what people are expecting. (Wayne Davison)
+
+ - A pattern with a "**" no longer causes a "*" to match slashes.
+ For example, with "/*/foo/**", "foo" must be 2 levels deep.
+ [If your string has BOTH "*" and "**" wildcards, changing the
+ "*" wildcards to "**" will provide the old behavior in all
+ versions.]
+
+ - "**/foo" now matches at the base of the transfer (like /foo
+ does). [Use "/**/foo" to get the old behavior in all versions.]
+
+ - A non-anchored wildcard term floats to match beyond the base of
+ the transfer. E.g. "CVS/R*" matches at the end of the path,
+ just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
+ to get the old behavior in all versions.]
+
+ - Including a "**" in the match term causes it to be matched
+ against the entire path, not just the name portion, even if
+ there aren't any interior slashes in the term. E.g. "foo**bar"
+ would exclude "/path/foo-bar" (just like before) as well as
+ "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
+ old behavior in all versions.]
+
+ * The exclude list specified in the daemon's config file is now
+ properly applied to the pulled items no matter how deep the
+ user's file-args are in the source tree. (Wayne Davison)
+
+ * For protocol version >= 27, mdfour_tail() is called when the
+ block size (including checksum_seed) is a multiple of 64.
+ Previously it was not called, giving the wrong MD4 checksum.
+ (Craig Barratt)
+
+ * For protocol version >= 27, a 64 bit bit counter is used in
+ mdfour.c as required by the RFC. Previously only a 32 bit bit
+ counter was used, causing incorrect MD4 file checksums for
+ file sizes >= 512MB - 4. (Craig Barratt)
+
+ * Fixed a crash bug when interacting with older rsync versions and
+ multiple files of the same name are destined for the same dir.
+ (Wayne Davison)
+
+ * Keep tmp names from overflowing MAXPATHLEN.
+
+ * Make --link-dest honor the absence of -p, -o, and -g.
+
+ * Made rsync treat a trailing slash in the destination in a more
+ consistent manner.
+
+ * Fixed file I/O error detection. (John Van Essen)
+
+ * Fixed bogus "malformed address {hostname}" message in rsyncd log
+ when checking IP address against hostnames from "hosts allow"
+ and "hosts deny" parameters in config file.
+
+ * Print heap statistics when verbose >= 2 instead of when >= 1.
+
+ * Fixed a compression (-z) bug when syncing a mostly-matching file
+ that contains already-compressed data. (Yasuoka Masahiko and
+ Wayne Davison)
+
+ * Fixed a bug in the --backup code that could cause deleted files
+ to not get backed up.
+
+ * When the backup code makes new directories, create them with mode
+ 0700 instead of 0755 (since the directory permissions in the
+ backup tree are not yet copied from the main tree).
+
+ * Call setgroups() in a more portable manner.
+
+ * Improved file-related error messages to better indicate exactly
+ what pathname failed. (Wayne Davison)
+
+ * Fixed some bugs in the handling of --delete and --exclude when
+ using the --relative (-R) option. (Wayne Davison)
+
+ * Fixed bug that prevented regular files from replacing
+ special files and caused a directory in --link-dest or
+ --compare-dest to block the creation of a file with the
+ same path. A directory still cannot be replaced by a
+ regular file unless --delete specified. (J.W. Schultz)
+
+ * Detect and report when open or opendir succeed but read and
+ readdir fail caused by network filesystem issues and truncated
+ files. (David Norwood, Michael Brown, J.W. Schultz)
+
+ * Added a fix that should give ssh time to restore the tty settings
+ if the user presses Ctrl-C at an ssh password prompt.
+
+ INTERNAL:
+
+ * Eliminated vestigial support for old versions that we stopped
+ supporting. (J.W. Schultz)
+
+ * Simplified some of the option-parsing code. (Wayne Davison)
+
+ * Some cleanup made to the exclude code, as well as some new
+ defines added to enhance readability. (Wayne Davison)
+
+ * Changed the protocol-version code so that it can interact at a
+ lower protocol level than the maximum supported by both sides.
+ Added an undocumented option, --protocol=N, to force the value
+ we advertise to the other side (primarily for testing purposes).

+ * Fixed the file-name duplicate-removal code when dealing with multiple
+ dups in a row. (Wayne Davison)
+
+ * Fixed a bug that caused rsync to lose the exit status of its child
+ processes and sometimes return an exit code of 0 instead of showing
+ an error. (David R. Staples, Dave Dykstra)
+
+ * Fixed bug in --copy-unsafe-links that caused it to be completely
+ broken. (Dave Dykstra)
+
+ * Prevent infinite recursion in cleanup code under certain circumstances.
+ (Sviatoslav Sviridov and Marc Espie)
+
+ * Fixed a bug that prevented rsync from creating intervening directories
+ when --relative-paths/-R is set. (Craig Barratt)
+
+ * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
+
+ INTERNAL:
+
+ * Many code cleanups and improved internal documentation. (Martin
+ Pool, Nelson Beebe)
+

+ * Some test-case fixes. (Brian Poole, Wayne Davison)
+
+ * Updated included popt to the latest vendor drop, version 1.6.4.
+ (Jos Backus)

+NEWS for rsync 2.5.5, aka Snowy River (2 Apr 2002)
+Protocol: 26 (unchanged)
+Changes since 2.5.4:
+
+ ENHANCEMENTS:
+
+ * With --progress, when a transfer is complete show the time taken;
+ otherwise show expected time to complete. (Cameron Simpson)
+
+ * Make "make install-strip" works properly, and "make install"
+ accepts a DESTDIR variable for help in building binary packages.
+ (Peter Breitenlohner, Greg Louis)
+
+ * If configured with --enable-maintainer-mode, then on receipt of
+ a fatal signal rsync will try to open an xterm running gdb,
+ similarly to Samba's "panic action" or GNOME's bug-buddy.
+ (Martin Pool)
+
+
+ BUG FIXES:
+
+ * Fix situation where failure to fork (e.g. because out of process
+ slots) would cause rsync to kill all processes owned by the
+ current user. Yes, really! (Paul Haas, Martin Pool)
+
+ * Fix test suite on Solaris. (Jos Backus, Martin Pool)
+
+ * Fix minor memory leak in socket code. (Dave Dykstra, Martin
+ Pool.)
+
+ * Fix --whole-file problem that caused it to be the default even
+ for remote connections. (Martin Pool, Frank Schulz)
+
+ * Work around bug in Mac OS X mkdir(2), which cannot handle
+ trailing slashes.
+ <http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html>

+
+ * Additional fix for zlib double-free bug. (Martin Pool, Andrew
+ Tridgell) (CVE CAN-2002-0059)
+
+ ENHANCEMENTS:
+
+ * Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus)
+ (Note that rsync still uses a custom version of zlib; you can
+ not just link against a system library. See zlib/README.rsync)

+ * Make sure that supplementary groups are removed from a server
+ process after changing uid and gid. (Ethan Benson) (Debian bug

+
+ BUG FIXES:
+
+ * Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE
+ CAN-2002-0059)
+
+ * Fixed problem that in many cases caused the error message
+ unexpected read size of 0 in map_ptr
+ and resulted in the wrong data being copied.
+
+ * Fixed compilation errors on some systems caused by the use of
+ "unsigned int64" in rsync.h.
+
+ * Fixed problem on systems such as Sunos4 that do not support realloc
+ on a NULL pointer; error was "out of memory in flist_expand".
+
+ * Fix for rsync server processes hanging around after the client
+ unexpectedly disconnects. (Colin Walters) (Debian bug #128632)
+
+ * Cope with BSD systems on which mkdir() will not accept a trailing
+ slash.
+
+ ENHANCEMENTS:
+
+ * Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that
+ rsync still uses a custom version of zlib; you can not just link
+ against a system library. See zlib/README.rsync)
+
+ * Command to initiate connections is only shown with -vv, rather
+ than -v as in 2.5.2. Output from plain -v is more similar to
+ what was historically used so as not to break scripts that try
+ to parse the output.
+
+ * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
+
+ * Made the --write-batch and --read-batch options actually work
+ and added documentation in the man page (Jos Backus)
+
+ * If the daemon is unable to fork a child to accept a connection,
+ print an error message. (Colin Walters)

+ careful about reading integers from the network.
+
+ BUG FIXES:
+
+ * Fix possible string mangling in log files.
+
+ * Fix for setting local address of outgoing sockets.
+
+ * Better handling of hardlinks and devices on platforms with
+ 64-bit dev_t or ino_t.
+
+ * Name resolution on machines supporting IPv6 is improved.
+
+ * Fix for device nodes. (dann frazier) (Debian #129135)
+
+ ENHANCEMENTS:
+
+ * With -v, rsync now shows the command used to initiate an ssh/rsh
+ connection.
+
+ * --statistics now shows memory heap usage on platforms that
+ support mallinfo().
+
+ * "The Ted T'so school of program optimization": make progress
+ visible and people will think it's faster. (With --progress,
+ rsync will show you how many files it has seen as it builds the
+ file_list, giving some indication that it has not hung.)
+
+ * Improvements to batch mode support. This is still experimental
+ but testing would be welcome. (Jos Backus)
+
+ * New --ignore-existing option, patch previously distributed with
+ Vipul's Razor. (Debian #124286)
