[PATCH 0/3] Avoid forking a process when checking merge bases

[PATCH 0/3] Avoid forking a process when checking merge bases

[Christian Couder]

The goal of this patch series is to check if good revisions are
ancestor of the bad revision without forking a process to launch
"git rev-list $good ^$bad".

To do that it introduces an "unparse_commit" function that may be
usefull in other cases, for example see:

Ps: sorry to send this cover letter late because of a bug in the
script I used to send the series.

  bisect: rework some rev related functions to make them more reusable
  commit: add function to unparse a commit and its parents
  bisect: check ancestors without forking a "git rev-list" process
