Re: [Vala] Equivalent for sqlitebck (sqlite backup)

Can't you just create a file with the DB in the SHM filesystem and then
copy it to the regular filesystem?

But I'm stuck on an equivalent for the Python module sqlitebck.

sqlitebck wraps the SQLite backup/restore procedures.

The applications 'opens' and SQLite database - restoring it to a
memory:// database - and 'saves' that in memory database back to an
SQLite on-disk database using sqlitebck.copy(source, target).

How would one do an equivalent thing in Vala?


You need to start by looking at the C 
API:https://www.sqlite.org/c3ref/backup_finish.html
This API is bound in Vala as an 
object:https://git.gnome.org/browse/vala/tree/vapi/sqlite3.vapi#n448
So you create a new Backup( ... ), do what the API advises and that's it. You 
don't need to free the object, the binding will call the correct free function 
for you.
