builtin-mailinfo.c infrastrcture changes I am working on a project that required parsing through regular mboxes that didn't necessarily have patches embedded in them. I started by creating my own modified copy of git-am and working from there. Very quickly, I noticed git-mailinfo wasn't able to handle a big chunk of my email. After hacking up numerous solutions and running into more limitations, I decided it was just easier to rewrite a big chunk of it. The following patch has a bunch of fixes and features that I needed in order for me do what I wanted. Note: I'm didn't follow any email rfc papers but I don't think any of the changes I did required much knowledge (besides the boundary stuff). List of major changes/fixes: - can't create empty patch files fix - empty patch files don't fail, this failure will come inside git-am - multipart boundaries are now handled - only output inbody headers if a patch exists otherwise assume those headers are part of the reply and instead output the original headers - decode and filter base64 patches correctly - various other accidental fixes I believe I didn't break any existing functionality or compatibility (other than what I describe above, which is really only the empty patch file). I tested this through various mailing list archives and everything seemed to parse correctly (a couple thousand emails). [jc: squashed in another patch from Don's five patch series to fix the test case, as this patch exposes the bug in the test.] Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
