Saves having to serialize the note fields and q/a templates, which
is particularly a win when rendering question/answer in the browse
screen.
Also some work towards being able to preview notes without having to
commit them to the database.
- notes with wrong field count are now recovered instead of
being deleted
- notes with missing note types are now recovered
- notes with missing cards are now recovered
- recover_missing_deck() still needs implementing
- checks required
May reduce the amount of seeking on conventional disks. Chunking and
fetching batches of notes at once would improve things further, at the
cost of more memory use.
changes to note:
- add_note() now takes a provided deck id instead of looking it up
in the notetype
- note type use counts fetched using a single table scan
- make sure note type changes are persisted
- expose optionalness of ords in templates and fields json
Still a prototype at this stage - we'll likely want a caching layer
for note types, and I'm not sure of the merit of having fields in
a separate table, since they're almost always required.
Some third party clients that create apkg files appear to be saving
a millisecond timestamp into this column. While this could also be
solved by increasing this field to a 64 bit number, some older clients
expect this column to be a 32 bit number.
- 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)
Disabled for now; when enabled it will allow faster collection
open and close in the normal case, while continuing to downgrade
when exporting or doing a full sync.
Also, when downgrading is disabled, the journal mode is no longer
changed back to delete.
- tag list stored in a separate DB table
- non-wildcard searches now do full unicode case folding
(eg tag:masse matches 'Maße')
- wildcard matches do simple unicode case folding
- some functions haven't been updated yet, so ascii folding will
continue to be used in some operations
