Some weird errors in Jenkins on post-ino64 -CURRENT

[Li-Wen Hsu]

Hi -java,

With FreeBSD cluster update, we migrated several Jenkins builders to
post-ino64 -CURRENT, but since then, we encountered several mysterious
errors.

What happens here is Jenkins (which uses SVNKit, subversion client library
written in Java) refuses checkout codes from svn.freebsd.org.  Some logs
like these:

https://ci.freebsd.org/job/FreeBSD-head-amd64-build/3674/console

  00:00:10.759 ERROR: Failed to check out svn://svn.freebsd.org/base/head
  00:00:10.760 org.tmatesoft.svn.core.SVNException: svn: E200030: BUSY

https://ci.freebsd.org/job/FreeBSD-head-amd64-build/3676/console

  00:00:00.104 ERROR: Failed to check out svn://svn.freebsd.org/base/head
  00:00:00.104 org.tmatesoft.svn.core.SVNException: svn: E155018:
'/jenkins/workspace/FreeBSD-head-amd64-build/src' already exists and is not
a directory

I've talked this with Ed at BSDCan, and we suspect this is related to
ino64.  Normally, recompiling the binaries should solve the problem.  But I
have tried to recompile everything that Jenkins depends on but it still
doesn't work.  I also tried to use openjdk7 to build a new openjdk7-version
bootstrap-openjdk but it still doesn't help.

This is reproducible with latest -CURRENT snapshot, installing Jenkins and
checking out codes from svn.freebsd.org.

Any ideas, suggest what to test next?


Thanks,
Li-Wen
