Download rsync 2.6.5

A new version of rsync has been released on the Samba.org website, which has been given 2.6.5 as the version number. The program provides a quick way to synchronize changes to a file to another location. It is therefore widely used in all kinds of synchronization programs, but also, for example, on file servers to be able to offer snapshot functionalities. If you want to know more about this, you can documentation read through which also lists some tutorials. The changelog looks like this:

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 (eg “n” -> “12”), 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 (ie 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 (eg 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 then 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” rel=”external”>,_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.
