mergetool: honor mergetool.$tool.trustExitCode for built-in tools

2016-11-29T18:54:03Z

Built-in merge tools contain a hard-coded assumption about whether or not a tool's exit code can be trusted to determine the success or failure of a merge. Tools whose exit codes are not trusted contain calls to check_unchanged() in their merge_cmd() functions. A problem with this is that the trustExitCode configuration is not honored for built-in tools. Teach built-in tools to honor the trustExitCode configuration. Extend run_merge_cmd() so that it is responsible for calling check_unchanged() when a tool's exit code cannot be trusted. Remove check_unchanged() calls from scriptlets since they are no longer responsible for calling it. When no configuration is present, exit_code_trustable() is checked to see whether the exit code should be trusted. The default implementation returns false. Tools whose exit codes can be trusted override exit_code_trustable() to true. Reported-by: Dun Peal Signed-off-by: David Aguilar Signed-off-by: Junio C Hamano

mergetools: stop setting $status in merge_cmd()

2014-11-21T19:27:53Z

No callers rely on $status so there's don't need to set it during merge_cmd() for diffmerge, emerge, and kdiff3. Signed-off-by: David Aguilar Signed-off-by: Junio C Hamano

mergetools/kdiff3: do not use --auto when diffing

2013-05-09T18:59:39Z

The `kdiff3 --auto` help message is, "No GUI if all conflicts are auto- solvable." This flag was carried over from the original mergetool commands. diff_cmd() is for two-way comparisons only so remove the superfluous flag. Signed-off-by: David Aguilar Signed-off-by: Junio C Hamano

mergetool--lib: Refactor tools into separate files

2011-08-19T07:09:19Z

Individual merge tools are now defined in a mergetools/$tool file which is sourced at runtime. The individual files are installed into $(git --exec-path)/mergetools/. New tools can be added by creating a new file instead of editing the git-mergetool--lib.sh scriptlet. http://thread.gmane.org/gmane.comp.version-control.git/134906/focus=135006 Signed-off-by: David Aguilar Signed-off-by: Junio C Hamano
