* Get rid of the dependency on RCS' merge programJohannes Schindelin2006-12-121-62/+13
| | | | | | | | Now that we have git-merge-file, an RCS merge lookalike, we no longer need it. So long, merge, and thanks for all the fish! Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
* Replace uses of strdup with xstrdup.Shawn Pearce2006-09-021-1/+1
| | | | | | | | | | | | | | | | Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code. [jc: removed the part that deals with last_XXX, which I am finding more and more dubious these days.] Signed-off-by: Shawn O.

* Improved three-way blob merging codeLinus Torvalds2006-06-281-0/+166
This fleshes out the code that generates a three-way merge of a set of blobs. It still actually does the three-way merge using an external executable (ie just calling "merge"), but the interfaces have been cleaned up a lot and are now fully based on the 'mmfile_t' interface, so if libxdiff were to ever grow a compatible three-way-merge, it could probably be directly plugged in. It also uses the previous XDL_EMIT_COMMON functionality extension to libxdiff to generate a made-up base file for the merge for the case where no base file previously existed. This should be equivalent to what we currently do in git-merge-one-file.sh: diff -u -La/$orig -Lb/$orig $orig $src2 | git-apply --no-add except it should be much simpler and can be done using the direct libxdiff interfaces.
