#1464 closed defect (fixed)

stronger isolation between the Python libraries imported by build steps and those used by buildbot

Reported by: davidsarah Owned by: somebody
Priority: major Milestone: 1.11.0
Component: dev-infrastructure Version: 1.8.2
Keywords: buildbot twisted pywin32 Cc:
Launchpad Bug:

Description (last modified by warner)

buildbot uses some of the same Python libraries as Tahoe, for example Twisted and pywin32. This creates problems for build steps that want to test what happens when those libraries are not installed, or when a version that is not compatible with buildbot is installed.

#1334 is a special case of this problem, and it also affects #1346.

Possible solutions include using virtualenv, or setting up PYTHONPATH differently for buildbot and for the code under test.

Something else that might help with this would be using exocet instead of the builtin Python module loader: #1443 "use exocet instead of the builtin Python module loader"

We now use tox and virtualenv, which gives us the isolation we need.
