Some issues I had when doing the setup again

[udovdh@…]

config session logging

[danielk]

looks like we're trying to fix a legacy DB table which hasn't been created yet..

[sphery <mtdean@…>]

If there is an issue (and I couldn't duplicate it--see other ticket), it's probably a dup of #5250.

[udovdh@…]

Yes and no. Yes it has the same fults but with more info and *also* other issues I encountered.

[danielk]

(In [17160]) Refs #5267. Fixes two chicken and egg problems with DB initialization.

The first is not to do the datadirect programid update if the DB is empty. This didn't do any harm, but caused some error messages to be logged. The second is not to do the database backup on an empty database, since it will fail to find settings and housekeeping tables.

There are some other problems running mythtv-setup to initialize the database, but these seem to be Qt4 port related. svn commit -m Refs

[danielk]

The end of that commit message got messed up, it should read: "This also skips printing a 'would you like to upgrade the schema' message on empty databases." not "svn commit -m Refs"

[danielk]

udovdh, I need a backtrace to fix your other problem, the segfault. See TicketHowTo.

[Nigel]

(In [17165]) Also test for DBSchemaVer of 0, which some users' setups are returning. See #5250, #5267

Which segfault exatcly? The qt4 one? This is 21-fixes so no qt4 but qt 3.3 AFAIK.

I assume Daniel meant the one at line 118 of your log:

Table 'mythconverg.settings' doesn't exist

2008-04-28 16:05:25.795 Couldn't upgrade database to new schema.

Here the setup crashed! Database connection is OK:

Hopefully, the original issue (not upgrading database) has now been fixed on 0-21-fixes and trunk.

[anonymous]

So I try without rebuilding software (and provide bt) and then with latest 21-fixes to confirm?

[danielk]

I didn't fix any segfaults, and I meant where you said "Here the setup crashed!" ... You only have to rebuild if the version you are running doesn't have debugging symbols.

[udovdh@…]

I stalled the mythtv debuginfo rpm. I backed up my database, dropped the database, used mc.sql to recreate the empty dB and ran mythtv-setup from gdb. I got complaints about no debuginfo in the debug files so I dunno of there's enough info. Here's the trace:

[danielk]

this looks like a problem somewhere in unichrome or Qt
