[PATCH v4 05/11] rebase: invoke post-rewrite hook

From
Thomas Rast <trast@student.ethz.ch>
Date
Feb 22, 2010, 00:10 UTC
Message-ID
<407d05a63f09aa006f8d1cd2fa4d1836e25dc9ac.1266797028.git.trast@student.ethz.ch>
In-Reply-To
<cover.1266797028.git.trast@student.ethz.ch>

We have to deal with two separate code paths: a normal rebase, which actually goes through git-am; and rebase {-m|-s}.

The only small issue with both is that they need to remember the original sha1 across a possible conflict resolution. rebase -m already puts this information in $dotest/current, and we just introduce a similar file for git-am.

Note that in git-am, the hook really only runs when coming from git-rebase: the code path that sets the $dotest/original-commit file is guarded by a test for $dotest/rebasing.
