The latest kdiff3 currently shipped with Tumbleweed is unsuitable for everyday use. I, for example, use it as my go-to `git mergetool` and I need that a lot. And it must be reliable and not messing up merge-output. Since the upgrade from 1.8.4 to 1.9.2, many regressions have to be experienced, please see the list of fixed issues below.
From a distribution point of view, I see two options: Fix-up 1.9.2 like proposed here, or (really!) downgrade to 1.8.5 until a new reliable 1.9 release comes out. I have contributed many fixes to upstream meanwhile.
- Remove GCC 11 build fix:
* 0001-Explicitly-include-limits-for-compatibility-with-gcc.patch
now contained in squashed patch
- Add collected fixes from upstream master:
* 0001-Collected-fixes-from-master.patch
contains the original and many more fixes:
+ misalignment and wrong conflict resolutions when using manual
alignment markers
+ uninitialized variables causing crashes
+ hangs and crashes due to wrong loop conditions
+ wrong handling of new-line at end-of-file
+ spurious insertion of empty lines in merge result
+ access of uninitialized iterators causing crashes
+ wrong buffer length calculations causing out-of-bounds access
+ wrong bit-logic causing comments to always be treated as white-space
+ crashes when hitting a key on empty merge results
+ technical details allowing fixes to be cherry-picked
