Forcing an svn revert on every checkout

[Galina Kistanova via llvm-commits]

Hello Zachary,

I do not think the svn revert would help in your case, as it seems your
problem is in unreliable access to the SVN server.
Here is what I see in the log (
http://lab.llvm.org:8011/builders/lldb-x86-windows-msvc2015/builds/18885/steps/svn-llvm/logs/stdio
):

Updating '.':
svn: E175012: Unable to connect to a repository at URL '
http://llvm.org/svn/llvm-project/llvm/trunk'
svn: E175012: Connection timed out

And then, on top of that you have issues with your file system:

exceptions.WindowsError: [Error 5] Access is denied:
u'C:\\buildbot\\lldb-windows-x86\\lldb-windows-x86\\llvm\\tools\\lldb\\packages\\Python\\lldbsuite\\test\\functionalities\\attach_resume\\AttachResume'

Given that, revert would not help at all, as it could fail the same way
because of the same reasons.
I think your only way is to solve the root problems, i.e. investigate and
fix the network issues, and fix whatever holds a lock (antivirus? indexer?).

Anyway, if you want to run svn revert, you can do so by adding a
ShellCommand​ step.

Thanks

Galina
