osync/CHANGELOG.md

SHORT FUTURE IMPROVEMENTS

• Tree functions execute piped commands (grep, awk) on local system when launched on remote slave which can cause more bandwith usage

FAR FUTURE IMPROVEMENTS

• MultiMaster support
  • Rethink of .osync_workdir/state/* files with PIDs, Host and Task Names to better identify multiple instances on the same fileset
  • Improve Master / Slave schema to Multimaster schema
  • State files should exist per replica for Multimaster schema

KNOWN ISSUES

• RC3 is tested against Linux, FreeBSD and MacOS X. More testing needed in MSYS Windows environment.
• Cannot finish sync if one replica contains a directory and the other replica contains a file named the same way (Unix doesn't allow this)

UNDER WORK

• sync test automation

RECENT CHANGES

• Added treat dir symlink as dir parameter
• 27 May 2014: Osync 0.99 RC3
• Additionnal delete fix for *BSD and MSYS (deleted file list not created right)
• Fixed dry mode to use non dry after run treelists to create delete lists
• Added follow symlink parameter
• Minor fixes in parameter list when bandwidth parameter is used
• Added some additionnal checks for *BSD and MacOS environments
• Changed /bin/bash to /usr/bin/env bash for sanity on other systems, also check for bash presence before running
• Changed default behavior for quick sync tasks: Will try to resume failed sync tasks once
• Some code cleanup for state filenames and sync action names
• Fixed deletion propagation (again). Rsync is definitly not designed to delete a list of files / folders. Rsync replaced by rm function which downloads deletion list to remote system.
• Added path detection for exclude list file
• Added a simple init script and an install script
• Fixed an issue with MacOSX using rsync -E differently than other *nix (Thanks to Pierre Clement)
• Multislave asynchronous task support (Thanks to Ulrich Norbisrath)
  • This breaks compat with elder osync runs. Add the SYNC_ID suffix to elder state files to keep deleted file information.
• Added an easier debug setting i.e DEBUG=yes ./osync.sh (Again, thanks to Ulrich Norbisrath)
• Added hardlink preservation (Thanks to Ulrich Norbisrath)
• Added external exclusion file support (Thanks to Pierre Clement)

• Fixed soft deletion not happening with relative paths
• Improved process termination behavior
• More code merging and cleanup
• Fixed a bug preventing deleted files in subdirectories propagation (Thanks to Richard Faasen for pointing that out)

• Improved forced quit command by killing all child processes
• Before / after commands are now ignored on dryruns
• Improved verbose output
• Fixed various typos
• Enforced CheckConnectivityRemoteHost and CheckConnectivity3rdPartyHosts checks (if one of these fails, osync is stopped)
• 18 Aug. 2013: Osync 0.99 RC1
• Added possibility to change default logfile
• Fixed a possible error upon master replica lock check
• Fixed exclude directorires with spaces in names generate errros on master replica tree functions
• Dryruns won't create after run tree lists and therefore not prevent building real run delete lists
• Softdelete and conflict backup functions are now time controlled
