help with git query

[E R]

Hi,

I'd like to generate the following report from git:

for each branch:
  - info about the latest commit on that branch (date and time, message, etc.)
  - info about the last time it was merged into master

What commands can I run to figure this out? I think I can figure out
the first one - it's the second one I'm having trouble with.

And if it would easier to do it from the C API (or something like the
perl Git::PurePerl module) I'd be interested in knowing that, too.

Thanks,
ER

Depending on what you want to do---from a bash shell, you could do:

for i in $(git branch -a | cut -b3-); do echo $i; git show -s $i; echo; done

>  - info about the last time it was merged into master

for i in $(git branch -a | cut -b3-); do echo $i; git show -s $(git
merge-base $i master); echo; done

Thanks - that's very helpful.

For the second question, is it possible to find the commit that
represents the merge in the master branch?

i.e.

   git merge-base XXX master

returns the commit in branch XXX that got merged into master. I'd like
to also find the commit that represents the merge in master.

There might not be an actual commit, if the merge was a fast forward.

If one exists, I think this might do what you want:

git log --pretty=oneline master --not $(git merge-base XXX master) | tail -1

Ick, please use the plumbing designed for this exact thing instead of
trying to parse "git branch":

  $ git for-each-ref --format='%(subject)
    %(authorname) %(authoremail)
    %(authordate)' refs/heads/

or however you want to format it. See "git help for-each-ref" for a list
of fields (you can also just pipe the output of for-each-ref into a
shell loop, as in your example, but with the format options there is
often no need).

git log --no-walk --branches --decorate --pretty=short

is what I use, sometimes. Some other "pretty" format might be more
suitable for your use case.
