Apache log from trying to open existing trac environment (deleted)

Description Matthew Gillen 2007-03-12 13:59:48 UTC
Description of problem:
trac- is linked against python-sqlite2.  Previous
versions were linked against python-sqlite3.  This makes old environments not
work with the new version, since they sqlite2-based version cannot read the
sqlite3 databases.  Trac should be linked against the sqlite3 version.

Version-Release number of selected component (if applicable):

Comment 1 Jeffrey C. Ollie 2007-03-12 14:32:03 UTC
Hmm...  Here are the requires for python-sqlite:  
python(abi) = 2.4
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1

And here are the requires for python-sqlite2:  
python(abi) = 2.4
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
sqlite >= 3.3.3

This looks to me like both versions of the sqlite python bindings link
against sqlite version 3.  AFAICS, there is no package named
python-sqlite3 in FC6.

Apache log from trying to open existing trac environment

These are the errors I got from apache when trying to access Trac URLs after
upgrading to trac- with python-sqlite2.

Comment 3 Matthew Gillen 2007-03-12 15:07:19 UTC
I realize now that the bug report title is misleading, since as you say, there
is no python-sqlite3.

So the old version (trac- was linked against python-sqlite, and the new
10.3.1-1 version is python-sqlite2 (but from what I now understand, both should
support sqlite3 databases).

The problem is still that the new version could not read my existing trac
databases.  I'm not sure why (the apache logs I attached earlier indicate that
it might be trying to do an upgrade), and given this new information about
python-sqlite2, it seems like there shouldn't be a problem.  But downgrading
made the problem illustrated by the apache logs go away, so there is certainly
something wrong.

Comment 4 Jeffrey C. Ollie 2007-03-12 15:14:39 UTC
Trac isn't really "linked" against python-sqlite or python-sqlite2.  The trac
code is supposed to auto-detect which one is installed.  If both are installed I
believe that it prefers the python-sqlite2 version based upon what I read in the
code.  When you upgraded trac was python-sqlite2 installed as a dependency when
it wasn't installed before?

Comment 5 Matthew Gillen 2007-03-12 15:19:03 UTC
Yes, exactly: python-sqlite2 was installed as a dependency for the update to

Comment 6 Matthew Gillen 2007-03-12 15:24:13 UTC
I got some info that this might be a known issue from the trac-users list:

A possible work-around is listed there, which involves tweaking apache's config.
 Looks like some sort of Apache cache is built.  I'll try to poke around an see
if I can't figure out how to clear it.

Comment 7 Matthew Gillen 2007-03-12 15:35:21 UTC
After carefully reading the bug report from comment #6, it seems that there is a
bug in python-sqlite2-2.3.2; the issue I described with trac is appearently
fixed by using python-sqlite-2.3.3.

I'll file a bug report against python-sqlite instead.

Comment 9 Jonathan S. Shapiro 2007-03-13 04:07:16 UTC
I'm the poster of I
just wanted to confirm that the workaround suggested there:

  rpm -e --nodeps python-sqlite2

has restored function on my system. If you are contemplating applying this
patch, I do suggest that you run "rpm -e" (without the --nodeps) to make sure
that the only dependency is trac. Trac will run fine after the removal.

Matt: what was the bug # for python-sqlite? I'ld like to track that one.

Comment 10 Jeffrey C. Ollie 2007-03-13 04:15:14 UTC
The python-sqlite2 bug is bug # 231848.

Comment 11 Jonathan S. Shapiro 2007-03-13 05:19:11 UTC
Thank you.

Comment 12 Matthew Gillen 2007-03-13 14:27:32 UTC
The latest version in Extras no longer depends on python-sqlite2.

Thanks for all your help.
