patches between commits

Bahadir Balban· Dec 12, 2005, 15:31 UTC · lore

Hi,

A very basic question - how could I generate patches across different commits?

Suppose I have a HEAD branch, which is the latest. And I want to generate `individual' patches for each commit I did since the beginning of development for this branch.

Secondly, is the sha1 of a tree what appears next to each commit when I type git-log? Is this the only command that lets us know the sha1's of commits?

Thanks, Bahadir

That is what I think "git format-patch <commit>" is for. It will generate patches to bring "<commit>" to HEAD.

"git rev-list", I think

Yes, but I think the real question Bahadir wants to know is what the <commit> parameter should be, if you want to export the whole history (I do not think there is any suitable argument to "format-patch" that does this).

Depends on what you have, to ask the question "what are their object names?".

 - I have this commit, how do I find out its object name?
   E.g. I want to know the HEAD commit's object name, second to
   the last commit on "test" branch.

   $ git rev-parse --verify HEAD
   $ git rev-parse --verify test^

 - I have bunch of commits leading to the head of my "test"
   branch.  What are they?

   $ git rev-list test ;# unadorned list of object names and nothing else
   $ git rev-list --pretty test ;# this is git-log
   $ git whatchanged -m -M -p test ;# with patch in full glory
