Increasing the priority since this is blocking a ChromeDriver release.

I think we can drop this back to Pri-1, since the release went out for Windows, Mac and Linux64. It's only Linux32 that's being delayed, so as long as this gets in the next few hours we're OK.

It's failing on the bot_update step, apparently a clobber is needed:

Gauri just noticed that it's looking for svn and failing:

running "git config remote.origin.url svn://svn.chromium.org/chrome-internal/trunk/src-internal" in "/b/build/slave/cache_dir/_cache_tmpK0fpMCsvn.chromium.org-chrome--internal-trunk-src--internal"
...
fatal: Unable to find remote helper for 'svn'

It seems we're still using svn for src-internal on these bots? So this could've started failing with:

https://chromium.googlesource.com/chromium/tools/depot_tools/+/3454ae85da8913a18a67adaaf8727fa9783127d3%5E%21/#F0

Aaron, do you know more about what's going on?

+iannucci@, who has also been working on bot_update.

SVN is no longer supported, so the waterfall's configuration should be updated to use Git.

That said, it's not a bad idea to have "bot_update" assert that the remote URL begins with http(s)?://.

Specifically, SVN references here should be changed to Git:

https://chromium.googlesource.com/chromium/tools/build/+/master/scripts/slave/recipes/chromium.chromedriver.recipe_autogen.py

Is https://chrome-internal.googlesource.com/chrome/src-internal.git the correct url?

I believe so, yeah.

Looks like we're past bot_update now:

Yep, on all platforms. Thanks for helping, I think we can close this.
