Cc: Trac Release:


I installed the TracWatchlistPlugin-1.0.1-py2.7.egg built from svn sources. But it breaks trac at start:

I also tried with empty configuration [watchlist]. I did upgrade the db before.

The workaround of installing Babel should work, however the issue should be fixed so that Babel is not required.

Please try the following patch.

  • watchlistplugin/0.12/tracwatchlist/

    diff --git a/watchlistplugin/0.12/tracwatchlist/ b/watchlistplugin/0.12/tracwatchlist/
    index 38a387d..eaff75a 100755
    a b class WatchlistPlugin(Component): 
    8989    def __init__(self):
    9090        # bind the 'watchlist' catalog to the specified locale directory
    91         locale_dir = resource_filename(__name__, 'locale')
    92         add_domain(self.env.path, locale_dir)
     91        try:
     92            locale_dir = resource_filename(__name__, 'locale')
     93        except KeyError:
     94            pass  # no locale directory
     95        else:
     96            add_domain(self.env.path, locale_dir)
    9498        #
    9599        self.realms = []

you can also try AnnouncerPlugin

comment:5 Changed 5 years ago by massimo.b@…

Thanks. Working now with that patch. Please integrate that, as Babel is optional in most environments.

While using AnnouncerPlugin at the same time, what benefit do I have from the WatchlistPlugin? Both offer a watch button on tickets and wikis.

Resolution: fixed

In 14415:

1.0.1: fixed a KeyError being raised when translations unavailable (closes #12176)

comment:7 Changed 5 years ago by Jun Omae

I think AnnouncerPlugin is currently unstable.

Replying to jun66j5:

I think AnnouncerPlugin is currently unstable.

Hm, where do you know that from? There is nothing about developing status or known bugs, no, at least for the release versions. Ok, I'm using trunk build ... Do you mean the comment "The email distribution is not as stable..."?

Experience using it. Also, take a look at the list of known issues and lack of development activity. If it is working for you in your use cases, great, but in general there are a lot of issues to beware of.
