Support content syndication using the RSS (Really Simple Syndication) XML format from Discussoins

[dgreen@…]

Please consider supporting RSS feed from discussion plugin.

[Radek Bartoň]

Discussion events are be recorded to Trac's timeline which has RSS format too. Do you mean that feature or something else?

[dgreen@…]

I do see discussions posted to timeline. I do have "discussions=on" in RSS feed but the discussions (neither first post in topic or successive posts) do not show in the feed.

I testested it recently but there could be something broken since. I'll take a look again.

[Radek Bartoň]

I've tested it and it seems that it works.

Using:

http://localhost:8000/Test/timeline?discussion=on&max=50&daysback=90&format=rss

I got:

<?xml version="1.0"?>
<rss version="2.0">

If are you getting something else please post more info about your sytem Trac version and so one...

Using that URL (modified for my server) strangely gives an RSS feed for the other components (Wiki, Changeset, Ticket, Milestones, etc. but no discussion.

Trac 0.9.5 Just downloaded Discussion Plug-in from Trac Hacks Using SQLITE3

In changeset 1038 I've added some debug outputs for timeline module. Could you please test it again with lastest changeset and then post relevant parts of debug log? Information about your web server where you run your Trac would be usefull too. Thank you.

[dgreen@…]

requested log file

[dgreen@…]

I used changeset 1048 which I believe, for the DiscussionPlugIn is the same thing.

Added another reply to an existing discussion and then a new topic within existing forum.

at 00:00:26 I hit it with (domain of server removed)

I see errors related to not having webadmin.web.ui loaded. Is that a dependency I missed? I thought it was optional.

bug500log.txt attached.

Using apache on/from SUSE 10.1, (Apache/2.2.0 (Linux/SUSE))

using an include to get:

If you don't have WebAdminPlugin installed don't use admin module of Discussion plugin (put tracdiscussion.admin.discussionwebadmin = disable) in [components] section in trac.ini). But I don't think that this is the problem with missing items in timeline. Post here please lines from your log starting with "Trac[timeline]". This could tell me more.

[Radek Bartoň]

Sorry, I didn't notice attachment.

[Radek Bartoň]

I studied log output. There is nothing wrong with timeline events generation and them should be corectly returned to Trac. Maybe error when loading non-existing module from WebAdminPlugin prevents Trac from display them so I was maybe wrong to say that this eror is not relevant. Please append or change

[components]
tracdiscussion.admin.discussionwebadmin = disable

line in your trac.ini. If this doesn't help error has to be somewhere between Trac and RSS page output.

[dgreen@…]

OK, anonymous did not have DISCUSSION_VIEW which was keeping the feed from being accessible (even when the feed request was supplying credentials). Giving anonymous DISCUSSION_VIEW gets feed to work but has the unfortunate side effect that I wanted to avoid of having folks be able to post without authentication.

Perhaps that would be an enhancement request to separate DISCUSSION_VIEW and DISCUSSION_POST/REPLY/PARTICIPATE (or whatever).

Additionally, FWIW, even disabling doing the

[components]
tracdiscussion.admin.discussionwebadmin = disable

Did not eliminate the message about webadmin.web.ui

So as it stands, I have to choose between anonymous discussion posters (no issue with viewers) and RSS feed.

Thanks for help. I think the behavior is by design (although that is your call) so probably this ticket could close and either one or two other tickets could be started (enhancement for splitting permissions VIEW from Participate, minor defect where discussionadmin tries to initialize even when disabled although that may be "by design" or within Trac).

[Radek Bartoň]

Defined permission is heritage from old Athomas's concept. They could be changed as you suggested. Anyway thank you for your clarification and interest.
