Description Aakash Jain 2019-07-11 13:19:31 PDT
Sometimes some bots gets into a state when git operations fail with an error: "fatal: Unable to create 'build/.git/index.lock': File exists." , e.g.: https://ews-build.webkit-uat.org/#/builders/40/builds/177

This usually happens when a git operation is interrupted (e.g.: by buildbot restart while git operation was running). Once that happens bot can't recover themself, and they burn through all the build-requests very quickly. This is pretty bad.

To make EWS robust against such issues, we should add build step to delete .git/index.lock file.
