Failing tests with Trac 0.11.5rc1, Darwin, Python 2.4

[osimons]

Latest (r648) gives two errors on my development setup. Tests also fails for r641, so failures are not caused by my committs. Still, need to look at why (suspecting some change in recent Trac):

These errors do not show up in the builds for Bitten itself on Linux (build:1470) or Windows (build:1471), so not quite sure what the magic difference is (platform and/or versions).

I'll look into adding a new step to our own build config that just prints out relevant environment information (such as Trac, Python and Subversion versions). That would help when researching such differences.

Would anyone mind if I updated the Bitten build script to record environment information? Here is what works in my local testing at least - adding a new environment recorder as first step:

  <step id="environment" title="Record environment information">
    <sh:exec executable="python"
      args="-c 'import platform; print &quot;Python:&quot;, platform.python_version()'" />
    <sh:exec executable="python"
      args="-c 'import trac; print &quot;Trac:&quot;, trac.__version__'" />
  </step>

On my (failing) setup this step just prints:

Python: 2.4.6
Trac: 0.11.5rc1

Got it. Fixed in [651].

As for recording environment information, that would still be useful as this example shows. I'll keep a note of that and add it to our own builds at some stage.
