Re: Migration from sqlite2 to sqlite3

Hi Frederik,

F-Spot does use sqlite3 by default. I mean, if both sqlite2 and sqlite3
are available on your system and you start f-spot for the first time,
your db will be version 3.

Upgrading your old db from version 2 to version 3 is pretty trivial, and
a script called f-spot-sqlite-upgrade is available in the tools folder
of the sources.

Right now, we can't auto-upgrade everyone database by running this
script to ease the pain of packages maintainers, cause this script need
both sqlite2 and sqlite3 installed at the same time (and if we do so, I
guess quite a lot of packages maintainers will start to become really
angry :) )

I know, upgrading the db is not a task that should be left to the user,
and most of the packaging systems do not have any ways to run scripts on
user owned files...

My guess is that the only working (but unelegant) option to solve both
user and maintainers headaches is, from a F-Spot point of view, bundle a
copy of sqlite2 in our tree and toolbox, and check for db version at
every start... hopefully this hack could be removed after 2 years or
more... Patch for this is welcome.

Hope this clarify the situation and helps you
