Bug 231836

Hmm...  Here are the requires for python-sqlite:

libc.so.6  
libc.so.6(GLIBC_2.0)  
libc.so.6(GLIBC_2.1.3)  
libc.so.6(GLIBC_2.3)  
libc.so.6(GLIBC_2.4)  
libpthread.so.0  
libsqlite3.so.0  
python(abi) = 2.4
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rtld(GNU_HASH)  

And here are the requires for python-sqlite2:

libc.so.6  
libc.so.6(GLIBC_2.0)  
libc.so.6(GLIBC_2.1.3)  
libc.so.6(GLIBC_2.3)  
libc.so.6(GLIBC_2.4)  
libpthread.so.0  
libsqlite3.so.0  
python(abi) = 2.4
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rtld(GNU_HASH)  
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-0.10.3.1-1.fc6.noarch.rpm with python-sqlite2.

I realize now that the bug report title is misleading, since as you say, there
is no python-sqlite3.

So the old version (trac-0.10.3.1) 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.

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?

Yes, exactly: python-sqlite2 was installed as a dependency for the update to
trac-0.10.3.1-1

I got some info that this might be a known issue from the trac-users list:
http://initd.org/tracker/pysqlite/ticket/146

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.

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.

I'm the poster of https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=231907. 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.

The python-sqlite2 bug is bug # 231848.

Thank you.

The latest version in Extras no longer depends on python-sqlite2.

Thanks for all your help.
