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
--------------

- 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)

- Replaced xargs rm with find -exec rm to better handle file names in soft deletion
- 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
