Changes since 2.17:
* The native OS X user interface has been enormously improved by Ben
Willmore and Trevor Jim.
* The backup functionality has been completely rewritten. The
external interface has not changed, but numerous bugs, irregular
behaviors, and cross-platform inconsistencies have been corrected.
* Some important safety improvements:
+ Added a new mountpoint preference, which can be used to
specify a path that must exist in both replicas at the end of
update detection (otherwise Unison aborts).
+ The confirmation of "big deletes" is now controlled by a
boolean preference confirmbigdeletes. Default is true, which
gives the same behavior as previously.
+ If Unison is asked to "follow" a symbolic link but there is
nothing at the other end of the link, it will now flag this
path as an error, rather than treating the symlink itself as
missing or deleted.
* Smaller changes:
+ Added forcepartial and preferpartial preferences
+ Refined debugging code so that the verbosity of individual
modules can be controlled separately. Instead of just putting
'-debug verbose' on the command line, you can put '-debug
update+', which causes all the extra messages in the Update
module, but not other modules, to be printed. Putting '-debug
verbose' causes all modules to print with maximum verbosity.
+ Rewrote some of the merging functionality, for better
cooperation with external Harmony instances.
+ Changed the temp file prefix from .# to .unison.
+ Compressed the output from the text user interface
+ Added .mpp files to the "never fastcheck" list
* Many small bugfixes, including:
+ Fixed a bug that would occasionally cause the archives to be
left in non-identical states on the two hosts after
synchronization.
+ Fixed a bug that prevented Unison from communicating
correctly between 32- and 64-bit architectures.
+ Set read-only file to R/W on OSX before attempting to change
other attributes.
+ Fixed bug resulting in spurious "Aborted" errors during
transport (thanks to Jerome Vouillon)
+ Enable diff if file contents have changed in one replica, but
only properties in the other.
+ Removed misleading documentation for 'repeat' preference.
+ Fixed a bug in merging code where Unison could sometimes
deadlock with the external merge program, if the latter
produced large amounts of output.
+ Workaround for a bug compiling gtk2 user interface against
current versions of gtk2+ libraries.
+ Added a better error message for "ambiguous paths".
+ Squashed a longstanding bug that would cause file transfer to
fail with the message "Failed: Error in readWrite: Is a
directory."
Main changelog entries:
- GUI improvements
- Improved error handling code. In particular, make sure all files are closed in case of a transient failure
- Improvements to syncing resource forks between Macs via a non-Mac system.
- Lots of changes, in summary:
- Archive format has changed
- Major tidying and enhancement of 'merge' functionality
- Files larger than 2Gb are now supported
- support for ocaml >3.07
- Substantial reworking of the internal logic of the text UI
version of unison (see pkgsrc/net/unison/DESCR) and is provided to allow
synchronizing against unison servers using version 2.9.2 of the Unison
protocol.
