Maintaining the Tycoon Trac

4/9/2007::

(klai) Experimented with Trac 0.11. Disastrous. Deal-breaker is need to convert custom templates from ClearSilver? to Genshi format.

1/9/2007::

(klai) Triggered an upgrade cycle up updating Mercurial.

5/23/2006::

(klai) Upgraded to trunk r3344 to try to fix hg changeset and self account registration problems

  • Had to patch Trac Mercurial plugin because hg looks for sys.argv, which doesn't exist in mod_python:

  • The above patch also prevents an error when looking at arbitrary diffs, which seemed to cause unbounded CPU utilization in httpd.
  • Changeset links now work
  • Image attachments can now be referred to as just

  • Account manager was bugged. Fixed using the following patches:

3/16/2006::

(klai) Upgraded to 0.10dev because TracMercurial plugin was updated

2/2/2006::

(klai) Aborted upgrade from Trac 0.9 to 0.9.3 for security patches. This consisted of the following steps:

  • Install 0.9.3 RPM
  • Remove /etc/httpd/conf.d/trac.conf
  • Get new version of account management and webadmin plugins
  • Web admin still did not work. Forgot to remove .zip extension from egg. Works now.
  • Mercurial plugin is incompatible.
  • Abandon patch of Trac macro.py code in favor of fixing Image reference by changing

    to 
    [Image(wiki:WikiStart:JeanLeonGeromeTheCarpetMarket.jpg, float:right, width: 20em)]]
  • Aborted because of Mercurial incompatibility. Will resume when Trac 0.10 is released.
