rerere: how to remove an erroneous resolution?

rerere: how to remove an erroneous resolution?

[SZEDER Gábor]

Hi,

some time ago I mistakenly resolved a merge conflict incorrectly.  Of
course, rerere noted the erroneous conflict resolution, and whenever
the same merge conflict occurs rerere offers me that erroneous
conflict resolution, even though I correct it each time.

So, the question is how could I make rerere forget that particular
merge conflict resolution?  Is it at all possible?


Thanks,
Gábor

Ok, I should have investigated a little longer before sending that
email.

I thought that .git/rr-cache contains some kind of sha1-named objects,
and did not realize that those are indeed directories with just
plaintext pre- and postimage files in it.  So, after some grepping I
could identify the sought conflict resolution fairly easily, and
correct it.

Best,
Gábor

Hmm. I have never actually used rerere in a real setting, so I am
somewhat clueless. But from your description, it sounds like it would
make sense for it to update the resolution to the latest one used. If
you changed it, it was probably to correct it; you would have no need to
make a change to break an already-working resolution.

Then you would not have had to go mucking about in .git.
