Fortunately, these cases are rare in +practice, and when they do occur, the worst case is simply a little +extra highlighting. This section documents some cases known to be +sub-optimal, in case somebody feels like working on improving the +heuristics. + +1. Two changes on the same line get highlighted in a blob. For example, + highlighting: + +---------------------------------------------- +-foo(buf, size); ++foo(obj->buf, obj->size); +---------------------------------------------- + + yields (where the inside of "+{}" would be highlighted): + +---------------------------------------------- +-foo(buf, size); ++foo(+{obj->buf, obj->}size); +---------------------------------------------- + + whereas a more semantically meaningful output would be: + +---------------------------------------------- +-foo(buf, size); ++foo(+{obj->}buf, +{obj->}size); +---------------------------------------------- + + Note that doing this right would probably involve a set of + content-specific boundary patterns, similar to word-diff.

The multi-line matching assumes that lines in the pre- and post-image + match by position.

Unless the lines in the middle are also changed, diffs + will show this as two hunks, and it will not get highlighted at all + (which is good).

To submit all changes that are in the current git branch but not in -the "p4" branch (or "origin" if "p4" doesn't exist) simply call - - git-p4 submit - -in your git repository. If you want to submit changes in a specific branch that -is not your current git branch you can also pass that as an argument: - - git-p4 submit mytopicbranch - -You can override the reference branch with the --origin=mysourcebranch option. - -The Perforce changelists will be created with the user who ran git-p4. If you -use --preserve-user then git-p4 will attempt to create Perforce changelists -with the Perforce user corresponding to the git commit author. You need to -have sufficient permissions within Perforce, and the git users need to have -Perforce accounts. Permissions can be granted using 'p4 protect'. - -If a submit fails you may have to "p4 resolve" and submit manually.
