- because the cutoff adds a few hours past midnight, it's possible for a card
that's scheduled for 1.0 days ahead to fall within the current cutoff, so we
need to make sure that doesn't happen
- set spaceUntil=0 when answering card again
- fix randomizeNewCards() query. the whole codebase needs auditing for type
references which need updating
* Adjust type to remove cards from the queues, so we don't have to rebuild
priorities to restore them:
Type -= 3 when suspending
Type += 3 when burying
Type += 6 when cramming / reviewing early
We still need to adjust priorities for backwards compatibility, but this can
be removed in the future.
* Factor out scheduler-specific code in answerCard(), so the different
schedulers are now fully modular
* Differentiate between a card's current queue and its type
* Make sure dueCutoff cuts off at the chosen offset instead of midnight
- new type, combinedDue for failed cards & count checks
- only reset() on deck load if not already done
- remove isDue from dynamic indices but leave old ones around for now
- cramming is now a separate scheduler type
- correctly answering a card while cramming causes its scheduling to be
changed in the standard review too
- options to sort cards by earliest modified, ordered, random
- render priority 0 obsolete, as it's all done at queue generation time now
- reimplement reviewEarly and newEarly by replacing parts of the scheduler,
instead of adding special conditions
- remove references to isDue and priority (1,2,3,4) which is not necessary
anymore
- add option to switch between per-day scheduling and due now scheduling
- newCardsToday() -> newCardsDoneToday()
- don't decrement counts for suspended cards
- make sure to update type when suspending/unsuspending
- fix findCards()
- set hardInterval = 1-1.1 on upgrade, or the default per day scheduling doesn't
make sense
Previously we used getCard() to fetch a card at the time. This required a
number of indices to perform efficiently, and the indices were expensive in
terms of disk space and time required to keep them up to date. Instead we now
gather a bunch of cards at once.
- Drop checkDue()/isDue so writes are not necessary to the DB when checking
for due cards
- Due counts checked on deck load, and only updated once a day or at the end
of a session. This prevents cards from expiring during reviews, leading to
confusing undo behaviour and due counts that go up instead of down as you
review. The default will be to only expire cards once a day, which represents
a change from the way things were done previously.
- Set deck var defaults on deck load/create instead of upgrade, which should
fix upgrade issues
- The scheduling code can now have bits and pieces switched out, which should
make review early / cram etc easier to integrate
- Cards with priority <= 0 now have their type incremented by three, so we can
get access to schedulable cards with a single column.
- rebuildQueue() -> reset()
- refresh() -> refreshSession()
- Views and many of the indices on the cards table are now obsolete and will
be removed in the future. I won't remove them straight away, so as to not
break backward compatibility.
- Use bigger intervals between successive card templates, as the previous
intervals were too small to represent in doubles in some circumstances
Still to do:
- review early
- learn more
- failing mature cards where delay1 > delay0
