V8 nightly tests failing, svn no longer supported

[mhdawson]

• Version: master
• Platform: all
• Subsystem: v8

The v8 test jobs started failing yesterday (the previous nightly run was ok).

See this as an example: https://ci.nodejs.org/job/node-test-commit-v8-linux/nodes=ppcle-ubuntu1404,v8test=v8test/370/console

On first glance it looks like the url is pointing to the node.js repo instead of the v8 repo

@ofrobots you aware of anything that went in yesterday that might be related ?

[matthewloring]

The builds seem to be failing at the tools/make-v8.sh v8 step. The last few successful runs of the CI printed this message at that step:

Oh hai! You are using subversion. Chrome infra is eager to get rid of svn support so please switch to git. Tracking bug: http://crbug.com/475320 If you are a project owner, you may request git migration assistance at: https://code.google.com/p/chromium/issues/entry?template=Infra-Git

I'm traveling to a conference next week so I won't be able to investigate in detail but have asked @jbajwa to take a look.

[jbajwa]

google build tool gclient doesn't support SVN anymore, hence we are seeing this error.

Need to update tools/make-v8.sh to use git alternate

[jbajwa]

I'm working on this issue. Will update the tools/make-v8.sh script to use the git alternate.

[jbajwa]

I updated the script to configure gclient with nodejs/v8.git repository, and performed "gclient sync". As per the documentation here, gclient sync should only pull dependencies mentioned in the DEPS file, but gclient sync seems to be updating the src as well, which is not the intended behaviour. I'm not quite sure how svn was setup before.
I'm going to request git migration assistance at the link provided in the warning msg before they nuked svn support.

Hi @s3ththompson,
I've opened a bug for assistance in migration to git. Could you help on this issue? Thank you.

[mhdawson]

@jbajwa any progress on this ?

[jbajwa]

@mhdawson
Hi Michael, I didn't get any update on the bug I opened regarding git migration assistance. I've decided to take another approach where I use gclient fetch to get the latest v8 (+ dependencies) and then do a git cleanup (checkout the files that were modified, and delete unstaged files). I've tested it and its working as expected.
Pull request #9393

[fhinkel]

@jbajwa Sorry for not hearing back on the issue. It's fall vacation time (and a holiday today). I'll ping a few people in the office tomorrow.

[mhdawson]

landed #9393 and updated build job. Looks all good now, closing.
