- mtime is tracked on each key individually, which will allow
merging of config changes when syncing in the future
- added col.(get|set|remove)_config()
- in order to support existing code that was mutating returned
values (eg col.conf["something"]["another"] = 5), the returned list/dict
will be automatically wrapped so that when the value is dropped, it
will save the mutated item back to the DB if it's changed. Code that
is fetching lists/dicts from the config like so:
col.conf["foo"]["bar"] = baz
col.setMod()
will continue to work in most case, but should be gradually updated to:
conf = col.get_config("foo")
conf["bar"] = baz
col.set_config("foo", conf)
- on collection load, the schema is upgraded to 12
- on collection close, the changes are reversed so older clients
can continue to open the collection
- in the future, we could potentially skip the reversal except
when exporting/doing a full sync
- the same approach should work for decks, note types and tags in the
future too
- the deck list code needs updating to cache the deck confs for the
life of the call
This is safer than just dropping the backend, as .close() will
block if something else is holding the mutex. Also means we can
drop the extra I18nBackend code.
Media syncing still needs fixing.
We no longer need to worry about pysqlite implicitly beginning
transactions, and can be more explicit about beginning/ending
transactions
save() now also has a trx argument controlling whether a
transaction should be started / left open
committing the Protobuf implementation for posterity, but will replace
it with json, as Protobuf measures about 6x slower for some workloads
like 'select * from notes'
- Adding files inside Anki now updates the media DB, so a full file
scan at sync time is no longer required if no other changes have been
made.
- Use a protobuf message for backend initialization, and return a
string error if initialization fails.
