[Buildbot-devel] Buildbot locks and multiple project features not working

[Kay Hayen]

Hello Dustin,

in fact, I did reproduce it, when I added it back to use, and I probably 
was only confused, but it seems, there was also locks = [ heavy_lock ] 
applied to all builds, so none was performed.

I now applied it only to the ones that I want to not build in paralell 
on the same slave and then I get this in the build log:

2013-12-10 07:40:02+0100 [-] <Build reflected-python2.7>.buildException

As you can see, I am on buildbot 0.8.8, and the way I create it is:

         ShellCommand(
            env={"PYTHON":python},
            command=command,
            locks = [] if not is_heavy else [ heavy_lock ]
         )

and it has been created lick this:

from buildbot.locks import SlaveLock
heavy_lock = SlaveLock("heavy")

The result in walterfall is a build exception when forcing it and status 
"not finished" in the build. And it says something like this:

2013-12-10 07:40:02+0100 [-]  <Build reflected-python2.7>: build finished
2013-12-10 07:40:02+0100 [-] releaseLocks(<BuildSlave 
'laptop-linux-slave'>): []

So, the multiple project feature is now working, but I still cannot use 
locks.

Yours,
Kay
