A writable git repo for collaboration and code dumps

[Isaac Levy]

Hi all,

We now have a blink repository which accepts pushes by

chromium committers. This repository keeps refs/heads/*

closely in sync with the official git mirror (normal delay <5s).

Here's a quickstart guide for using:
1) Navigate to https://chromium.googlesource.com/, log in with your
    chromium account, click 'Generate New Password', and follow the
    instructions.
2) cd <blink_src>; git remote add -f wip https://chromium.googlesource.com/experimental/chromium/blink
<hack on some code, commit locally>
3) git push wip HEAD:refs/wip/ilevy/awyeah

This creates a publicly accessible branch. Any developer can pull

with: git fetch wip '+refs/wip/ilevy/awyeah:refs/heads/awyeah'

You can also run:

git config --add remote.wip.fetch '+refs/wip/ilevy/*:refs/wip/ilevy/*'

and then use 'git fetch wip'

Please restrict pushes to the refs/wip namespace, specifically in the

following format: refs/wip/<username or codeword>/<branch name>

That's all for now :-)

Cheers,

Isaac

FAQ:

Q: Why not change my origin url to the experimental remote?

A: Gclient sync will change origin back to the official mirror.

    Patches to gclient (specifically gclient_scm.py::update) are welcome.

Q: git push freezes!

A: The wip remote may be stale. Try running git fetch wip.

Q: How do I delete a branch?

A: Users with push also have delete (and force push) permissions.

    git push wip :refs/wip/ilevy/iaccedentally

Q: There's another chromium git repository that I want to collaborate on.

A: Send me an email.

Update: gclient patch has landed.  Improved workflow below:

Instead of adding a second remote, I'd suggest changing your origin

remote to the experimental branch.

Replace steps 2-3 with:

2) cd <blink src>; git config remote.origin.url https://chromium.googlesource.com/experimental/chromium/blink

3) git config remote.origin.gclient getoffmylawn

4) git remote update

Then push to origin instead of wip, i.e.: git push origin HEAD:refs/wip/ilevy/blah

[Isaac Levy]

Apologies, the magic git config entry to prevent gclient sync from resetting origin url has changed again.  The new instructions are:

2) cd <blink src>; git config remote.origin.url https://chromium.googlesource.com/experimental/chromium/blink

3) git config remote.origin.gclient-auto-fix-url False

4) git remote update

I finally tried to use this today:

1) I created the new user/password

2) I tried to push a new branch in from my repo:

$ git push -u wip navcontroller

Username for 'https://chromium.googlesource.com': git-alecflett.chromium.org

Password for 'https://git-alecflett...@chromium.googlesource.com':

To https://chromium.googlesource.com/experimental/chromium/blink

 ! [remote rejected] navcontroller -> navcontroller (read-only)

error: failed to push some refs to 'https://chromium.googlesource.com/experimental/chromium/blink'

Are we not allowed to create branches in the new repository?

Also, I closed the tab that had the username/password and now I have no idea where to retrieve that from or create a new username/password..

You need to push to a specific namespace:

3) git push wip HEAD:refs/wip/ilevy/awyeah

This creates a publicly accessible branch. Any developer can pull

with: git fetch wip '+refs/wip/ilevy/awyeah:refs/heads/awyeah'

You can also run:

git config --add remote.wip.fetch '+refs/wip/ilevy/*:refs/wip/ilevy/*'

and then use 'git fetch wip'

Please restrict pushes to the refs/wip namespace, specifically in the

following format: refs/wip/<username or codeword>/<branch name>

So you should be doing something like:

git push wip HEAD:refs/wip/alecflett/navcontroller

However, if you've changed your origin as described below, you'll need to use something more like: (though from the command you gave, it doesn't look like this applies)

git push origin HEAD:refs/wip/alecflett/navcontroller

Hope that helps,

So I'm trying to setup an experimental branch, and I'm getting a "fatal: remote error: Git access forbidden" when I try to push. I know this is a lame thing to say, but I'm pretty confident I've followed ilevy's instructions to the 't', and I've tried several times at this point. Has anything changed with these repos, or am is this a "good back and try again because you're clearly screwing something obvious up" kind of moment? Here are the commands I've run (in order, after CD'ing into my Blink src and putting my creds in .netrc):

git remote add -f wip https://chromium.googlesource.com/experimental/chromium/blink

git config --add remote.wip.fetch '+refs/wip/jww/*:refs/wip/jww/*'

git fetch wip

git push wip HEAD:refs/wip/jww/testbranch

I had a permissions problem out of the box, and it turned out to be because my @google.com address and not my @chromium.org address had been added to commi...@chromium.org. Asking mal nicely rectified this.

So... it might be that. YMMV.

Ah, there's the problem... I'm not a committer yet :-) I didn't realize that I needed to be a committer to push an experimental branch. Problem solved, thanks!

[Isaac Levy]

Right. If this is an issue for others, we could consider setting up a whitelist group.  Maybe it's time to become a committer :-)
