problems with hg plugin

[Matt Fair]

I'm having horrible reliability issues with the mercurial retrieving
via hgweb, specifically for one of my matrix jobs where I have a total
of 4 jobs. The error I get is:

$ hg log --rev 39d1d4c9d7496469ffbdea22cdad48c96642dc70

Could there be an issue with all of my jobs trying to hit the hgweb at
the same time? The repository hgweb server is running locally. Is
there a way to not have to use hgweb and instead just give the local
path to the repository?

Is anyone else having this problem? If I re-run the jobs, they will
work and others will fail, completely random. Which makes me believe
it could be an issue retrieving the change log via hgweb because it's
being hit simultaneously by 4 jobs.

Thanks,
Matt

I tried the local file system instead of giving a URL and it didn't
work for remote hosts, as the repository isn't local to those
machines, only for the CI server.

I switched from 'hg serve' to
http://mercurial.selenic.com/wiki/modwsgi using Apache and that fixed
my problem.
