I do not see how such a major change can be justified in a minor point

sqlite database on Debian Sid since they package it with sqlite 3.2.5.
Shouldn't this have waited for 4.0?
XMMS2 also stoped working for sid and gentoo users and we got a shitload
On the other hand I was forced to rewrite the horrible sqlite3 support.
While on the subject I have a few questions.
How "expensive" is it to open a new sqlite3 handler? My new method
doesn't really cache the handlers, could this be a problem?
My new internal api looks something like this:
each part of the code that would like to change something in the db
needs to aquire a session:
session = xmms_medialib_begin();
this will open a sqlite3 handler and do some checking of the db.
then make some changes:
xmms_medialib_entry_property_set_int (session, entry, key, value);
and then end it:
and this will close it.
At first I used a transaction that automaticly begun when you did
medialib_begin(). But I got a lot of strange "Database is locked" errors.
This seems to occur when this happens:
thread1: insert ()
thread2: select () -> EBUSY
thread1: commit -> EBUSY
to solve this you have to rollback thread2 before you can commit
thread1. It was a strange behaviour that didn't fit my code at all so I
reverted to not using transactions, this works well but probably hurt my
Is there a better way to handle this?
