This happens up to a few times per week or more. Let get it onto Kitware's radar.

I have yet to be inconvenienced myself, but @jamiesnape @BetsyMcPhail, PTAL?

Has anyone observed this on a non-Ninja build?

We have enough information now and are trying to reproduce. Post if there is a failure that is not Linux and Ninja.

mwoehlke-kitware commented 7 years ago

RobotLocomotion/drake-ci#62 will hopefully give us some information if it happens again, and should also work around the problem by retrying the failed git command. Builds that have git errors should show as 'unstable'. (For build-cop purposes, these can be treated as "clean", but the strace output should be inspected for clues.)

SeanCurtis-TRI commented 7 years ago

This cropped up again. This time affecting libccd. Per @jamiesnape's request, this is in a mac build.

liangfok commented 7 years ago

@SeanCurtis-TRI can you provide a link to the console log or CI build page?

SeanCurtis-TRI commented 7 years ago

Sorry, here you go: https://drake-jenkins.csail.mit.edu/view/Nightly%20Production/job/mac-clang-ninja-nightly-minimal-debug/160/

jamiesnape commented 7 years ago

(Aside: CDash links persist longer than Jenkins links)

SeanCurtis-TRI commented 7 years ago

I suspected that might be the case, which is why the original posting used a cdash link.

mwoehlke-kitware commented 7 years ago

The build should not have failed outright, however. Looking closer, there are issues other than the "could not lock config file" problem:

The failure despite succeeding on retry is due to a stupid logic error in the wrapper, fixed by RobotLocomotion/drake-ci#70. What is interesting however are the errors from the submodule sync attempt, which makes me wonder if all the "could not lock config file" errors are merely symptomatic of something having gone wrong earlier...

Demoting high -> medium, because the git retry logic is helping, and because in BazelDrake land we won't be shelling out to git commands for submodules anymore.
