613723 - hg diff --git does not include base revision in output

Status: RESOLVED WONTFIX

(Tamarin Graveyard :: Tools, enhancement)

Description

[Felix S. Klock II [:pnkfelix, :fklock]]

A discussion amongst the team revealed a short-coming of generating git-formatted diff's from Mercurial: it does not include the base revision in its output, which can sometimes be useful information for someone planning to apply a patch.

Illustration:

hgplay/diffdemo % hg log
changeset:   0:594fee7fd309

I am not the only person who has noticed this; perhaps a solution will appear here:
  http://stackoverflow.com/questions/2967493/mercurial-include-revisions-in-git-diff

but if none appears there, it would be worth a couple hours of effort to see if its easy to make a Mercurial extension that added that first line of information back in.
