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 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).
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 code reading a filter/exclude file an EINTR error, rsync now clears
the error flag on the file handle so it can keep on reading.
- 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.
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.
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
