Auto-upgrade a Trac environment

Notice: This plugin does not necessarily meet coding standards or functions correctly in all use cases.


The AutoUpgradePlugin, when enabled, will automatically upgrade the environment when it needs an upgrade. Except for checking for the AutoUpgradePlugin being enabled, it is equivalent to a small patch to trac.env:

  • trac/

    594594            env.log.error("Exception caught while checking for upgrade: %s",
    595595                          exception_to_unicode(e, traceback=True))
    596596        if needs_upgrade:
    597             raise TracError(_('The Trac Environment needs to be upgraded.\n\n'
    598                               'Run "trac-admin %(path)s upgrade"',
    599                               path=env_path))
     597            try:
     598                env.upgrade(backup=True)
     599            except TracError, e:
     600                env.upgrade()
    601602    return env
