[PATCH v3 00/10] transport-helper: updates

[Felipe Contreras]

Hi,

Here are the patches that allow transport helpers to be completely transparent;
renaming branches, deleting them, custom refspecs, --force, --dry-run,
reporting forced update, everything works.

Some of these were were sent before and rejected without a reason, but here
they are again in case anybody is interested.

Diff from v2:

[PATCH v3 03/10] transport-helper: check for 'forced update' message

[Felipe Contreras]

So the remote-helpers can tell us when a forced push was needed.

[PATCH v3 02/10] transport-helper: fix extra lines

[Felipe Contreras]

Commit 9c51558 (transport-helper: trivial code shuffle) moved these
lines above, but 99d9ec0 (Merge branch 'fc/transport-helper-no-refspec')
had a wrong merge conflict and readded them.

Looks awfully familiar to:

http://article.gmane.org/gmane.comp.version-control.git/235973

But since the project does have double standards, you might have
better luck by simply not using my name.

Ahh, nevermind, it's a fix on top of my patch. I actually found this
and fixed it on my local branch, but didn't push it. Now I have.

These patches don't cleanly apply to master anymore; would you be
willing to rebase and post a new version?

I wanted to test these changes via git-remote-bzr on a bzr repository
I'm working on, but unfortunately git-remote-bzr doesn't yet support
force pushes.  I may look into adding force push support to
git-remote-bzr, unless you beat me to it.  :)

In general these patches look good to me and I'd like to see them merged
to master.

Thanks,
Richard
