Cannot create forums with Trac 1.0.1.

Severity: normal Keywords: ProgrammingError, closed, cursor

Description

Hi,

I'm trying to use the plug-in in Trac 1.0.1.

I use changeset:9787 of ​http://trac-hacks.org/svn/discussionplugin/0.11.

I'm unable to create forums.

I get the following Trac error in the timeline. 

Event provider DiscussionTimeline failed for filters "Discussion changes": ProgrammingError: Cannot operate on a closed cursor.

The log file includes: 

2014-02-20 16:46:15,809 Trac[web_ui] ERROR: Timeline event provider failed:

Any idea of what is going on?

By the way, I also tried with changeset:13444 and had the same issues.

The db object goes out of scope in api.get_changed_forums. Fix is on the way.

comment:2 Changed 11 years ago by anonymous

Hi,

Thanks for your comment. By the way, the error goes away if I disable 

DiscussionTimeline	(tracdiscussion.timeline.*)

This still does not enable me to create forums so perhaps there are two issues here.

Thanks,

Vincent

comment:3 Changed 11 years ago by Ryan J Ollos

Activity at log:discussionplugin/0.11 shows that r9787 is far out of date. I'll work on resolving the timeline issue, but please upgrade to the latest before we go hunting for the issue about creating forums, since it may already be fixed.

comment:4 Changed 11 years ago by Ryan J Ollos

In 13706:

0.9dev: Fix for Cannot operate on a closed cursor because db object is out-of-scope when using the cursor to retrieve timeline events. Refs #11592.

comment:5 Changed 11 years ago by Ryan J Ollos

Would you kindly let me know if both your issues are resolved after upgrading to 0.9dev-r13706?

Hi,

Thank you for the great support.

The timeline issue is indeed resolved.

I'm still unable to create forums though.

I originally tried with changeset:13444 and could not create forums. I then tried changeset:9787 since DiscussionPlugin#PluginVersions seemed to indicate that changeset:9787 could be the most stable version.

What should be the next step?

Regards,

Vincent

Thanks, I've removed that comment. I would advise running r13706, as it contains all the bug fixes.

I'll need more information on what happens when you try to create a forum. Any errors or tracebacks? Anything in TracLogging?

I do not get any errors.

What database backend are you using?

Replying to rjollos:

What database backend are you using?

How do I retrieve this information?

comment:11 Changed 11 years ago by Ryan J Ollos

You [trac] database string is a good indicator. Does it begin with postgres:, mysql: or sqlite:?

comment:12 Changed 11 years ago by anonymous

We have the following: 

[trac]
database = sqlite:db/trac.db

Please set [trac] debug_sql = true and post the recording from the log when creating a forum (see TracIni#trac-section).

Thanks, I will reply shortly.

comment:16 Changed 11 years ago by Ryan J Ollos

So after you create a forum from /discussion, you are redirected back to /discussion and you just see?:

Forum List

There are no forums created.

comment:17 Changed 11 years ago by Ryan J Ollos

In 13708:

0.9dev: Keep db object in scope when using a cursor. Refs #11592.

Also fixed an unresolved import and removed logging of SQL because it is implicitly logged (see the [trac] debug_sql configuration item).

comment:18 Changed 11 years ago by Ryan J Ollos

Okay, I think the issue is the same - the db object is going out of scope. I implemented the changes quickly, and they are extensive, so more testing will be needed. Would you kindly test it out and report back?

comment:19 Changed 11 years ago by anonymous

Hi,

comment:16 accurately captures the issue that I'm experiencing.

Just tried changeset:13708 and I still cannot create forums.

Here is what I find in the log file.

That's frustrating. Can you create a forum from the admin page?: /admin/discussion/forum.

comment:21 Changed 11 years ago by anonymous

It does not work either.

Excellent! It looks like there are several places that we might see a similar problem. I'll have a more thorough change committed within the hour.

comment:26 Changed 11 years ago by anonymous

I do not know if that is related but editing the subject or the description of a forum after having created it does not work...

comment:27 Changed 11 years ago by Ryan J Ollos

In 13709:

0.9dev: Do a db.commit after each transaction, because having a single db.commit doesn't seem to be effective either due to scoping issues, or because the statement isn't encountered in certain scenarios. Refs #11592.

comment:28 Changed 11 years ago by Ryan J Ollos

Hopefully will be fixed after [13709], but please let me know if you spot anything.

comment:29 Changed 11 years ago by Ryan J Ollos

Also, please go ahead and close the ticket whenever you are satisfied that the issues have been resolved. Thanks!

comment:30 Changed 11 years ago by anonymous

Resolution: → fixed
Status: accepted → closed

Hi,

I have tried changeset:13709 and I can now create forums as well as edit their subjects or descriptions after the fact.

Closing the case.

Thank you for the outstanding support.

Regards,

Vincent

Thank you for all the testing and following through on the issue. It's particularly hard to fix a defect that I can't reproduce, so this wouldn't have been fixed without your help. The cannot operate on closed cursor errors are mysterious in that they are often not seen by all users. I have no idea what factors determine whether or not they will be seen. The issue has come up rather frequently in various contexts.

Does this help? ​https://groups.google.com/forum/#!msg/trac-dev/trRtzv5waoQ/Uz1T1sBhTR8J

  • when a connection is put back in the cache, or rather, as soon as the connection wrapper you got from get_db_cnx() gets garbage collected, the connection is rolled back
  • rollback used to fail when there with active cursors, for old pysqlite version (<= 2.3.3), so for each connection we maintain a list of active cursors, and before the actual rollback we explicitly close the cursors
  • anyway, newer pysqlite versions would do that by themselves (pysqlite:#197)

works [only when] there are other references kept on that "db" higher in the stack (if a db is active, get_db_cnx() from within the same thread is guaranteed to return it

comment:34 Changed 11 years ago by Ryan J Ollos

The changes made so far were based on the principle of keeping the db object active and in scope.

We are both running a 1.0.x version of Trac though; I'm using Python 2.7. There must be some difference in our environments that is leading to the issue appearing in yours, but not mine.

Indeed. I've been adding another preventive measure in [13887].

comment:36 in reply to:  17 Changed 11 years ago by Steffen Hoffmann

Replying to rjollos:

Also fixed an unresolved import and removed logging of SQL because it is implicitly logged (see the [trac] debug_sql configuration item). }}}

Almost. Keep in mind, that this option was added after Trac 0.11, but in general I still agree to the notion of reducing debug logging for clarity.
