----------------------- x.y.z (to be announced) ----------------------- - Improved error diagnostics for the kill subcommand. - The --no-resume option has been removed. - The gengetopt option parser has been replaced by the [lopsub](http://people.tuebingen.mpg.de/~maan/lopsub) library. Hence lopsub must be installed to compile this package. Also help2man is no longer required since lopsub has built-in roff support. - "make install" will install the executable and the man page. - In run mode, dss no longer exits successfully if another instance is already running. - New option --checksum to let rsync compute checksums occasionally. - CFLAGS, CPPFLAGS and LDFLAGS can now be used to override the flags of the build system. ------------------ 0.1.7 (2017-04-17) ------------------ - Documentation improvements. - Improved error diagnostics. - dss no longer refuses to run in daemon mode without a log file. - Minor tweaks to the snapshot pruning algorithm. - A fix for create mode when rsync exists unsuccessfully. - NEWS and README have been converted to markdown format. - We now compile with -Wunused-parameter and -Wshadow. ------------------ 0.1.6 (2015-08-05) ------------------ - New option --min-complete to specify the minimal number of snapshots to keep. - Improved handling of rsync errors. The new --max-rsync-errors option tells dss to terminate after the given number of rsync failures. - New home page URL and email address. - Reworked rsync restart logic, new --max-rsync-errors option. - Avoidance of "Errors with program diagnostics" error from rsync. - Improved signal handling. ------------------ 0.1.5 (2014-01-14) ------------------ - snapshot recycling: outdated, redundant and orphaned snapshots are reused as the basis for new snapshots. - New subcommands: --kill, --reload. - The semaphore-based locking system prevents to start multiple instances of dss. - When dss receives SIGHUP it now writes the internal state and the configuration to the log file - First steps to make the source code ANSI C conform (thanks to Daniel Richard G). - dss writes log messages to stderr rather than to the logfile unless running in daemon mode. - Default hooks work also on systems where "/bin/true" does not exist, e.g. Mac OS. ------------------ 0.1.4 (2010-11-08) ------------------ This version of dss contains some new features, many improvements of existing features and several bug fixes. Support for resuming snapshot creation after restart has been added and snapshot removal is deferred until at least one current snapshot exists. The internal handling of the various hooks has been simplified and many error messages have been clarified. On SIGHUP, dss now writes its configuration and internal state to the log file. ------------------ 0.1.3 (2009-06-06) ------------------ You can now specify pre-rm/post-rm-hooks that are executed whenever a snapshot is deleted. This release adds better compatibility with rsync 3.0, and avoids busy loops when automatically restarting the rsync process. ------------------ 0.1.2 (2009-03-05) ------------------ This release includes the reason why a snapshot gets removed in the log message. It will never remove the snapshot that is currently being created. It will really pass the full path to the last complete snapshot in the post_create_hook. ------------------ 0.1.1 (2008-11-13) ------------------ This release prevents busy loops on rsync exit code 13. It ignores any snapshot directory with creation time >= completion time. It opens /dev/null for reading and writing when executing rsync. It shows human readable snapshot creation duration when listing snapshots. It restarts the rsync process if it returned with exit code 13. ------------------ 0.1.0 (2008-10-10) ------------------ Initial public release.
