+NEWS for rsync 2.6.5 (1 Jun 2005)
+Protocol: 29 (unchanged)
+Changes since 2.6.4:
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.
+ - 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.
- - 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.)
-
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).
+ - 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.
- - The combination of --verbose and --dry-run now mentions changes in
- directories and it now includes the full update information that
- would be output without --dry-run at higher levels of verbosity.
+ - Fixed a bug in the transfer of a single file when -H is specified
+ (rsync would either infinite loop or perhaps crash).
- - Avoid a mkdir warning when removing a directory in the destination
- that already exists in the --backup-dir.
+ - 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).
- - An OS that has a binary mode for its files (such as cygwin0 needed
- setmode(fd, O_BINARY) called on the temp-file we opened with
- mkstemp(). (Fix derived from the cygwin's rsync package.)
+ - 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 a potential hang when verbosity is high, the client side is
- the sender, and the file-list is large.
+ - Fixed the accidental disabling of --backup during the --delete-after
+ processing.
- - We now check if the OS doesn't support using mknod() for creating
- FIFOs and sockets, and compile-in using mkfifo() and socket() when
- necessary.
+ - Restored the ability to use the --address option in client mode (in
+ addition to its use in daemon mode).
- - Fixed an off-by-one error in the handling of --max-delete=N.
+ - 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.
- - One place in the code wasn't checking if fork() failed.
+ - When --existing skips a directory with extra verbosity, refer to it
+ as a "directory", not a "file".
- - The "ignore nonreadable" daemon parameter no longer affects symlinks
- that are being copied, even if they point nowhere.
+ - 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.
- - If the OS does not have lchown() and its chown() tries to set the
- referent of a symlink (as it should), we no longer try to set the
- user and group of a symlink.
+ - Fixed a bug where hard-linking a group of files might fail if the
+ generator hasn't created a needed destination directory yet.
- - 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.
+ - 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 --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.
+ - 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.
- - One call to flush_write_file() was not being checked for an error.
+ - Fixed a compatibility problem when using --cvs-ignore (-C) and
+ sending files to an older rsync without using --delete.
- - The --no-relative option was not being sent from the client to a
- server sender.
+ - Make sure that a "- !" or "+ !" include/exclude pattern does not
+ trigger the list-clearing action that is reserved for "!".
- - If an rsync daemon specified "dont compress = ..." for a file and the
- client tried to specify --compress, the libz code was not handling a
- compression level of 0 properly. This could cause a transfer failure
- if the block-size for a file was large enough (i.e. rsync might have
- exited with an error for large files).
+ - Avoid a timeout in the generator when the sender/receiver aren't
+ handling the generator's checksum output quickly enough.
- - If a daemon can't open the specified log file (i.e. syslog is not
- being used), die without crashing. We also try to output an error
- about the failure (which will only be seen if --no-detach was
- specified).
+ - Fixed the omission of some directories in the delete processing when
+ --relative (-R) was combined with a source path that had a trailing
+ slash.
- - A local transfer no longer duplicates all its include/exclude options
- by sending the forked process a copy of the list it already has.
+ - Fixed a 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.
- ENHANCEMENTS:
+ - Make sure that --max-size doesn't affect a device or a symlink.
- - Rsync now supports popt's option aliases, which means that you can
- use /etc/popt and/or ~/.popt to create your own option aliases.
-
- - Added the --delete-during (--del) option which will delete files
- from on the receiving side incrementally as each directory in the
- transfer is being processed (which makes it more efficient than the
- default, before-the-transfer behavior of --delete). Note that the
- --del option is implemented as an internally-defined popt alias, so
- an rsync daemon that refuses "delete" (which, for safety's sake,
- really matches "delete*") will still refuse all delete options. The
- default --delete behavior is also explicitly selectable via
- --delete-before.
-
- - All the --delete-WHEN options are now more memory efficient:
- Previously an entire duplicate set of file-list objects was created
- on the receiving side for the entire destination hierarchy. The new
- algorithm only creates one directory of objects at a time.
-
- - Added the --copy-dest option, which works like --link-dest except
- that it includes copies of identical files.
-
- - Added support for specifying multiple --compare-dest, --copy-dest, or
- --link-dest options, but only of a single type. (Promoted from the
- patches dir and enhanced.)
-
- - Added the --max-size option. (Promoted from the patches dir.)
-
- - The daemon-mode options were separated from the normal rsync options
- so that they can't be mixed together. This makes it impossible to
- start a daemon that had improper default option values that could
- cause problems (such as a hang or an abort) when a client connects.
-
- - The --bwlimit option may now be used in combination with --daemon
- to specify both a default value for the daemon side and a value
- that cannot be exceeded by a user-specified --bwlimit option.
-
- - Added the "port" parameter to the rsyncd.conf file. (Promoted from
- the patches dir.) Also added "address". A command-line option
- will take precedence over a config-file option, as expected.
-
- - In _exit_cleanup(): when we are exiting with a partially-received
- file, we now flush any data in the write-cache before closing the
- partial file.
-
- - The --inplace support was enhanced to work with --compare-dest,
- --link-dest, and (the new) --copy-dest options. (Requires protocol
- 29.)
-
- - Added the --dirs (-d) option for an easier way to copy directories
- without recursion.
-
- - Added the --list-only option which is mainly a way for the client to
- put the server into listing mode without needing to resort to any
- option kluges (e.g. the age-old use of "-r --exclude="/*/*" for a
- non-recursive listing). This option is used automatically when a
- modern rsync speaks to a modern daemon, but may also be specified
- manually if you want to force the use of the --list-only option over
- a remote-shell connection.
-
- - Added the --omit-dir-times (-O) option which will avoid updating the
- modified time for directories when --times was specified. This
- option will avoid an extra pass through the file-list at the end of
- the transfer (to tweak all the directory times), which can result in
- an appreciable speedup for a really large transfer. (Promoted from
- the patches dir.)
-
- - Added the --filter (-f) option and its helper option, -F. Filter
- rules are an extension to the existing include/exclude handling
- that also supports nested filter files as well as per-directory
- filter files (like .cvsignore, but with full filter-rule parsing).
- This new option was chosen in order to ensure that all existing
- include/exclude processing remained 100% compatible with older
- versions. (Protocol 29 needed for full filter-rule support, but
- backward-compatible rules work with earlier protocol versions.)
-
- - Added the --delay-updates option that puts all updated files into
- a temporary directory (by default ".~tmp~", but settable via the
- --partial-dir=DIR option) until the end of the transfer. This
- makes the updates a little more atomic for a large transfer.
-
- - If rsync is put into the background, any output from --progress is
- reduced.
-
- - Documented the "max verbosity" setting for rsyncd.conf. (This
- setting was added a couple releases ago, but left undocumented.)
-
- - The sender and the generator now double-check the file-list index
- they are given, and refuse to operate on a directory index (since
- that would indicate that something had gone very wrong).
-
- SUPPORT FILES:
-
- - Added support/atomic-rsync -- a perl script that will transfer some
- files using rsync, and then move the updated files into place all at
- once at the end of the transfer. Only works when pulling, and uses
- --link-dest and a parallel hierarchy of files to effect its update.
-
- - Added support/mnt-excl that takes the /proc/mounts file and
- translates it into a set of excludes that will exclude all mount
- points (even mapped mounts to the same disk). The excludes are made
- relative to the specified source dir and properly anchored.
-
- - Added support/savetransfer.c -- a C program that can make a copy of
- all the data that flows over the wire. This lets you test for data
- corruption (by saving the data on both the sending side and the
- receiving side) or provides a way to help debug a protocol error.
-
- - Added support/rrsync -- my version of Joe Smith's restricted rsync
- perl script. This helps to ensure that only certain rsync commands
- can be run by an ssh invocation.
-
- - Improved the option descriptions in the --help text.
+ - 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.)
- INTERNAL:
+ - 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).
- - Added better checking of the checksum-header values that come over
- the socket.
+ - 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.
- - Merged the various delete-file functions into a single function so
- that it is easier to maintain.
+ - If --stats is specified with --delete-after, ensure that all the
+ "deleting" messages are output before the statistics.
- - Improved the type of some variables (particularly blocksize vars) for
- consistency and proper size.
+ - 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).
- - Got rid of the uint64 type (which we didn't need).
+ ENHANCEMENTS:
- - Use a slightly more compatible set of core #include directives.
+ - 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).
- - Defined int32 in a way that ensures that the build dies if we can't
- find a variable with at least 32 bits.
+ - 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.
- PROTOCOL DIFFERENCES FOR VERSION 29:
+ - 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.
- - If --inplace is specified, the generator sends an extra byte after
- each index integer indicating what kind of basis file is being used
- for the transfer (see the FNAMECMP_* defines).
+ - 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!)
- - 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).
+ - 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).
- - 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".)
+ - 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).
- - When talking to a protocol 29 rsync daemon, a list-only request
- is able to note this before the options are sent over the wire, and
- the new --list-only option is enabled.
+ - 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:
- - 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).
+ - 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).
- - When --delete-excluded is specified with some filter rules (AKA
- excludes), a client sender will still initiate a send of the filter
- rules to the receiver, but it only includes those rules that are
- receiver-specific. Older protocols used to omit the sending of
- excludes in this situation (since there were no receiver-specific
- rules that survived --delete-excluded back then).
+ - Improved the naming of the log-file open/reopen/close functions.
- - A protocol-29 batch file includes a bit for the setting of the --dirs
- option. Also, the shell script created by --write-batch will use the
- --filter option instead of --exclude-from to capture any filter rules.
+ - Removed some protocol-compatibility code that was only needed to help
+ someone running a pre-release of 2.6.4.
BUILD CHANGES:
- - Handle an operating system that use mkdev() in place of makedev().
+ - 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.
- - Improved configure to better handle cross-compiling.
+ - Added a few new *.diff files to the patches dir, including a patch
+ that enables the optional copying of extended attributes.
