NEWS for rsync 3.0.8 (26 Mar 2011)
Protocol: 30 (unchanged)
Changes since 3.0.7:
BUG FIXES:
- Fixed two buffer-overflow issues: one where a directory path that is
exactly MAXPATHLEN was not handled correctly, and one handling a
--backup-dir that is extra extra large.
- Fixed a data-corruption issue when preserving hard-links without
preserving file ownership, and doing deletions either before or during
the transfer (CVE-2011-1097). This fixes some assert errors in the
hard-linking code, and some potential failed checksums (via -c) that
should have matched.
- Fixed a potential crash when an rsync daemon has a filter/exclude list
and the transfer is using ACLs or xattrs.
- Fixed a hang if a really large file is being processed by an rsync that
can't handle 64-bit numbers. Rsync will now complain about the file
being too big and skip it.
- For devices and special files, we now avoid gathering useless ACL and/or
xattr information for files that aren't being copied. (The un-copied
files are still put into the file list, but there's no need to gather
data that is not going to be used.) This ensures that if the user uses
--no-D, that rsync can't possibly complain about being unable to gather
extended information from special files that are in the file list (but
not in the transfer).
- Properly handle requesting remote filenames that start with a dash. This
avoids a potential error where a filename could be interpreted as a
(usually invalid) option.
- Fixed a bug in the comparing of upper-case letters in file suffixes for
--skip-compress.
- If an rsync daemon has a module configured without a path setting, rsync
will now disallow access to that module.
- If the destination arg is an empty string, it will be treated as a
reference to the current directory (as 2.x used to do).
- If rsync was compiled with a newer time-setting function (such as
lutimes), rsync will fall-back to an older function (such as utimes) on a
system where the newer function is not around. This helps to make the
rsync binary more portable in mixed-OS-release situations.
- Fixed a batch-file writing bug that would not write out the full set of
compatibility flags that the transfer was using. This fixes a potential
protocol problem for a batch file that contains a sender-side I/O error:
it would have been sent in a way that the batch-reader wasn't expecting.
- Some improvements to the hard-linking code to ensure that device-number
hashing is working right, and to supply more information if the hard-link
code fails.
- The --inplace code was improved to not search for an impossible checksum
position. The quadruple-verbose chunk[N] message will now mention when
an inplace chunk was handled by a seek rather than a read+write.
- Improved ACL mask handling, e.g. for Solaris.
- Fixed a bug that prevented --numeric-ids from disabling the translation
of user/group IDs for ACLs.
- Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
option (e.g. --link-dest) could output an error trying to itemize the
changes against the alt-dest directory's xattr/ACL info but was instead
trying to access the not-yet-existing new destination directory.
- Improved xattr system-error messages to mention the full path to the
file.
- The --link-dest checking for identical symlinks now avoids considering
attribute differences that cannot be changed on the receiver.
- Avoid trying to read/write xattrs on certain file types for certain OSes.
Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
NO_SPECIAL_XATTRS defines in config.h.
- Improved the unsafe-symlink errors messages.
- Fixed a bug setting xattrs on new files that aren't user writable.
- Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
- Fixed a bug with --fake-super when copying files and dirs that aren't
user writable.
- Fixed a bug where a sparse file could have its last sparse block turned
into a real block when rsync sets the file size (requires ftruncate).
- If a temp-file name is too long, rsync now avoids truncating the name in
the middle of adjacent high-bit characters. This prevents a potential
filename error if the filesystem doesn't allow a name to contain an
invalid multi-byte sequence.
- If a muli-protocol socket connection fails (i.e., when contacting a
daemon), we now report all the failures, not just the last one. This
avoids losing a relevant error (e.g. an IPv4 connection-refused error)
that happened before the final error (e.g. an IPv6 protocol-not-supported
error).
- Generate a transfer error if we try to call chown with a -1 for a uid or
a gid (which is not settable).
- Fixed the working of --force when used with --one-file-system.
- Fix the popt arg parsing so that an option that doesn't take an arg will
reject an attempt to supply one (can configure --with-included-popt if
your system's popt library doesn't yet have this fix).
- A couple minor option tweaks to the support/rrsync script, and also some
regex changes that make vim highlighting happier.
- Fixed some issues in the support/mnt-excl script.
- Various manpage improvements.
ENHANCEMENTS:
- Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).
DEVELOPER RELATED:
- Use lchmod() whenever it is available (not just on symlinks).
- A couple fixes to the socketpair_tcp() routine.
- Updated the helper scripts in the packaging subdirectory.
- Renamed configure.in to configure.ac.
- Fixed configure's checking for iconv routines for newer OS X versions.
- Fixed the testsuite/xattrs.test script on OS X.
