Repeatability
We want to be able to check certain configuration into svn that can be checked out and reproduced.
We let buildout tell what versions it picked for distributions
Run with -v
Look for outout lines of form:
Picked: foo = 1.2
Include a versions section:
[buildout] ... versions = myversions [myversions] foo = 1.2 ...
Deployment issues
- Need a way to record the versions of eggs used.
- Need a way to generate distributable buildouts that contain all of the source distributions needed to build on a target machine (e.g. source RPMs).
- Need to be able to generate source distributions. We need a way of gathering the sources used by a buildout so they can be distributed with it.
PyPI availability
A fairly significant issue is the availability of PyPI. PyPI is sometimes not available for minutes or hours at a time. This can cause buildout to become unusable.
