KeyError: 'announcer/locale' on email notification

[Crunk]

I am using Trac 0.12 and moved from Announcer-Plugin 1.0-a1 to 0.12-p2.dev (trunk).

Now, each time a ticket is changed Trac experiences an error. I attached the error information page.

AnnouncerPlugin is configured as follows:

[components]
announcer.api.announcementsystem = enabled
announcer.distributors.mail.emaildistributor = enabled
announcer.formatters.ticket.ticketformatter = enabled
announcer.formatters.wiki.wikiformatter = enabled
announcer.pref.announcerpreferences = enabled

announcer.subscribers.ticket_custom.ticketcustomfieldsubscriber = enabled

If you need further information... let me know

Oh well. You're aware, that we added i18n stuff lately, right? So you need to take care about the fancy additional command

python ./setup.py compile_catalog

before packaging. The error you present suggests that something went wrong and directory announcer/locale (holding translatable strings catalogs in different languages) never got created (inside the Python egg). You have Babel >= 0.9.5 installed, don't you?

Most probably it is related to this, so need to push it up to highest prio. :-) Still we might, and possibly we will resort to a more backwards-compatible implementation soon. Until then you'll be out of luck, if you don't take care for this additional dependency, even for native-English applications. Sorry for that, there is a learning curve with developers too. And thanks for taking care and reporting back. Would like to see you continuing your feedback.

Hello again.

Now, I am not getting crashes any more.

After killig and repairing my complete Trac installation after installing Babel (I did not have installed Babel on Trac installation) (see Trac Bug #9439 ​http://trac.edgewall.org/ticket/9439 and solution ​http://trac.edgewall.org/ticket/9439#comment:16 AnnouncerPlugin still did not work as intended.

After one more hour of investigation I found out that the option email_enabled = true also has to be set, and it worked. As mentioned in other Bugs this parameter should be better documented.

AnnouncerPlugin sends mail on correct events... but not using the configured smtp server as it seems... I will keep investigating....

[Steffen Hoffmann]

I've just finished a major rewrite of AnnouncerPlugin's wiki page and hope, that you'll find it easier now to get relevant information for a quick start. Any comments are still appreciated.

[Robert Corsaro]

I've turned email_enabled to true by default. I've also changed the way install works so that locales are automatically compiled. You'll still need to make sure Babel is installed before installing TracAnnouncer

My recent comment on #7314 applies here as well.

[Steffen Hoffmann]

(In [10920]) AnnouncerPlugin: Refactor i18n in a more compatible way, refs #7314, #7666, #7380, #8062 and #9192.

Lessons learned meanwhile with other plugins, so the code applied here has actually been tested and proven to work. This reverts [8409] effectively, but let's keep proper Babel and Trac versions for i18n explicitly as an extra.

After these changes the plugin finally loads cleanly in Trac 0.11 again.
