Subject: bug#2676: 23.0.91; annoying/unnecessary vc-next-action conflict in vc-dir buffer
Date: Sun, 15 Mar 2009 11:57:36 +0900

[Note: I have Dan's patch for fixing whole-directory vc-dir commit in
Git applied, though I don't think it should affect the following, as it
relates to final commit.]

If I have a vc-dir buffer showing a tree with a new file (not yet
registered with source-control), and a changed file (already
registered):

   VC backend : Git
   Working dir: /tmp/zonk/
   Branch     : master

                            ./
        unregistered        newf4
        edited              ppling

Then hitting "v" on the first line of the buffer gives the following
error:

   vc-dir-deduce-fileset: /tmp/zonk/ppling:edited clashes with /tmp/zonk/newf4:unregistered

While I guess I understand the reason for this, it's slightly annoying.

Given vc-next-action's "do-the-right-next-thing" functionality, it would
seem better in such a case to instead do a "register files only" step
(ignoring any changed-but-already-registered entries); subsequently, the
user could just hit "v" again to commit everything (the old changed file
and the files newly registered by the first "v").

I think this behavior would be a better match for vc-next-action's
behavior on single files.

Because registering/deregistering files is typically a local and
easily reversible operation, it would be "safe".

[Probably the "register files only" step should handle deletions too,
unregistering any deleted files.]

Thanks,

-Miles
