The cron job that runs patchtest sometimes (twice this year) is unable to test incoming patches because some incoming data (patches?) is causing the share folder to get corrupted. The first time this happened [1], the git commands under the latter folder could not be done, indicating corruption on the .git folder, and the second one [1], someone the credentials were removed. [1] first series untested by patchtest the first time this year https://patchwork.openembedded.org/series/6725/ [2] first series untested by patchtest the second time this year https://patchwork.openembedded.org/series/7405/
This is a workaround to avoid filesystem corruption http://git.yoctoproject.org/cgit/cgit.cgi/patchtest/commit/?h=master-next&id=beda622775cbdce6315afc0a46aa6c3f7e5cbb9d The commit message describes in detail the problem and findings. the commit is in master-next so will be merged into master as soon as the testing finishes.
