[devel at bb.net] Buildbot on Mac OS X

[Craig Treleaven]

Hi:

Sorry if you are seeing this for the second time.  I posted on the users list and it was suggested that perhaps I should repost on devel...

I’m attempting to set up a Mac OS X buildbot slave for the MythTV project.  They haven’t had a Mac builder for several years and so I need to temporarily set up a buildbot master to work out the build process.  However, my initial attempts have been stymied by the sqlalchemy / sqlalchemy-migrate situation.

I also contribute a bit to the MacPorts package management system so I want to use that to install buildbot. It appeared to install OK but everytime I try to run ‘buildbot start blah’ or ‘buildbot checkconfig blah’, I get the following error message (full log below):

	exceptions.AttributeError: Requirements are not satisfied for buildbot.changes:GitPoller: (sqlalchemy-migrate 0.10.0 (/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages), Requirement.parse('sqlalchemy-migrate==0.7.2’))

Indeed, MacPorts installs  py27-sqlalchemy-migrate version 0.10.0 .  However, it is from (a new fork) at:

http://sqlalchemy-migrate.googlecode.com/

This fork had quite a few releases in 2014 and 2015.  

Has buildbot not been tested with the newer releases of sqlalchemy-migrate?  Or are there still compatibility problems?

Craig
PS I don’t know Python, much less the various python package processes.  I’m willing to get changes made at MacPorts to fix the package there.
