Show ticket relative changelogs


This plugin adds a changelog list in a Trac ticket.

Compose your log message with a ticket reference pattern. The default pattern in versions 0.12 and 1.0 of the plugin is to add #ticketid before the log messages:

#ticketid any messages

In version 1.2 of the plugin the CommitTicketUpdater options are used to configure the pattern. With the default option values, patterns such like refs #1 and fixes #2 will be matched.

Tested with Subversion, Mercurial and Git.


For mercurial backend, since TracMecurial does not support the repository cache yet, you should install TracMercurialChangesetPlugin to generate the repository cache.


For the Git backend, you should add following config to the [git] section of your trac.ini file:

cached_repository = true
persistent_cache = true

You need to run trac-admin repository resync after the change.

You can install this plugin following the standard procedures described in TracPlugins.

  1. Uninstall TracTicketChangelogPlugin if you have installed it before.
  2. Change to the directory containning
    • (Optional): If you have Babel installed and would like to have translations available:
      python compile_catalog -f
  3. If you want to install this plugin globally, you need to install this plugin to the Python path:
    • python install
  4. If you want to install this plugin to the Trac instance only:
    • python bdist_egg
    • copy the generated egg file to the Trac instance's plugin directory
      cp dist/*.egg /srv/trac/env/plugins
  5. Add the following to the trac.ini file in the components section:
    ticketlog.* = enabled
    ; optional: custom your log message pattern
    log_pattern = ^\s*#%s[:\s]+.*$  # version 0.12 and 1.0
    ; optional: set log message's max length, default is no limit
    log_message_maxlength = 100
  6. (Version 1.2) Sync the ticket-revision table:
    $ trac-admin $env ticketlog sync
    You must configure repository caching and explicit synchronization, and resync all of the repositories before running ticketlog sync.


In version 0.12 and 1.0 of the plugin you can configure log_pattern:

  • %s in the pattern will be replaced with the referenced ticket number (e.g. 12345), so \s*#%s+\s+.* will be evaluated as \s*#12345+\s+.*.
  • (?:\n|[^#])*#%s(?:\D|$) matches ticket references in the form #xyz anywhere in the commit message.
    See comment:5:ticket:7884

In version 1.2 of the plugin, the pattern is configured using the CommitTicketUpdater options.
