The progress bar add-ons appear to be the only active users of it;
they can switch their old code from iterating over the list to
simply locating the selected deck in deckDueTree(), as its counts should
summarize all the child decks.
- front/back/css shown in tabs
- front/back preview switchable; only one webview needs to be loaded
- dropdown to select cloze number in preview
- search box to search in front/back/css
Like adding individual cards, we now support importing material even
if it wouldn't generate any cards, and the old availOrds check can't
handle negated conditionals.
- changes are now committed in bulk when closing the dialog,
and can be canceled
- it's not necessary to save the note to the database to preview it
- duplicate fields are now shown as duplicates in the top list
- redraw preview more quickly
- use + instead of _ when deduplicating names, as the latter is a
glob character
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.
Originally removed because some users were adding cloze deletions to
it, but removing it just replaced that problem with a new problem where
users add the field but don't add it to their card templates.
If the schema confirmation dialog is shown on a background thread it
will crash the app, so we convert this to an assertion error that gets
caught by the error handler. Code still needs to be updated to modify
the schema prior to moving to the background, but at least this way
it doesn't crash.
