* Collection needs to be closed prior to backup even when not downgrading
* Backups -> BackupLimits
* Some improvements to backup_task
- backup_inner now returns the error instead of logging it, so that
the frontend can discover the issue when they await a backup (or create
another one)
- start_backup() was acquiring backup_task twice, and if another thread
started a backup between the two locks, the task could have been accidentally
overwritten without awaiting it
* Backups no longer require a collection close
- Instead of closing the collection, we ensure there is no active
transaction, and flush the WAL to disk. This means the undo history
is no longer lost on backup, which will be particularly useful if we
add a periodic backup in the future.
- Because a close is no longer required, backups are now achieved with
a separate command, instead of being included in CloseCollection().
- Full sync no longer requires an extra close+reopen step, and we now
wait for the backup to complete before proceeding.
- Create a backup before 'check db'

* Defer checkpoint until we know we need it
When running periodic backups on a timer, we don't want to be fsync()ing
unnecessarily.
* Skip backup if modification time has not changed
We don't want the user leaving Anki open overnight, and coming back
to lots of identical backups.
* Periodic backups
Creates an automatic backup every 30 minutes if the collection has been
modified.
If there's a legacy checkpoint active, tries again 5 minutes later.
* Switch to a user-configurable backup duration
CreateBackup() now uses a simple force argument to determine whether
the user's limits should be respected or not, and only potentially
destructive ops (full download, check DB) override the user's configured
limit.
I considered having a separate limit for collection close and automatic
backups (eg keeping the previous 5 minute limit for collection close),
but that had two downsides:
- When the user closes their collection at the end of the day, they'd
get a recent backup. When they open the collection the next day, it
would get backed up again within 5 minutes, even though not much had
changed.
- Multiple limits are harder to communicate to users in the UI
Some remaining decisions I wasn't 100% sure about:
- If force is true but the collection has not been modified, the backup
will be skipped. If the user manually deleted their backups without
closing Anki, they wouldn't get a new one if the mtime hadn't changed.
- Force takes preference over the configured backup interval - should
we be ignored the user here, or take no backups at all?
Did a sneaky edit of the existing ftl string, as it hasn't been live
long.
* Move maybe_backup() into Collection
* Use a single method for manual and periodic backups
When manually creating a backup via the File menu, we no longer make
the user wait until the backup completes. As we continue waiting for
the backup in the background, if any errors occur, the user will get
notified about it fairly quickly.
* Show message to user if backup was skipped due to no changes
+ Don't incorrectly assert a backup will be created on force
* Add "automatic" to description
* Ensure we backup prior to importing colpkg if collection open
The backup doesn't happen when invoked from 'open backup' in the profile
screen, which matches Anki's previous behaviour. The user could
potentially clobber up to 30 minutes of their work if they exited to
the profile screen and restored a backup, but the alternative is we
create backups every time a backup is restored, which may happen a number
of times if the user is trying various ones. Or we could go back to a
separate throttle amount for this case, at the cost of more complexity.

Ideally this would have been in beta 6 :-) No add-ons appear to be
using customstudy.py/taglimit.py though, so it should hopefully not be
disruptive.
In the earlier custom study changes, we didn't get around to addressing
issue #1136. Now instead of trying to determine the maximum increase
to allow (which doesn't work correctly with nested decks), we just
present the total available to the user again, and let them decide. There's
plenty of room for improvement here still, but further work here might
be better done once we look into decoupling deck limits from deck presets.
Tags and available cards are fetched prior to showing the dialog now,
and will show a progress dialog if things take a while.
Tags are stored in an aux var now, so they don't inflate the deck
object size.

This brings the behaviour a bit closer to the default ordering of new
cards when they are reset, and is better than an undefined template
order. But it's a stopgap solution, and in the long run, filtered decks
need a bit of a rethink with the improved ordering than v3 has brought.
This was broken by an SQLite upgrade - previously we received the rows
in ix_cards_sched order, but recent versions use a table scan for that
query when the order is unspecified. Solved by being explicit about the
order we expect results to arrive.
https://forums.ankiweb.net/t/skipping-new-cards/15410
Matches should arrive in alphabetical order. Currently results are not
capped (JS should be able to handle ~1k tags without too much hassle),
and no reordering based on match location is done. Matches are substring
based, and multiple can be provided, eg "foo::bar" will match
"foof::baz::abbar".
This is not hooked up properly on the frontend at the moment -
updateSuggestions() seems to be missing the most recently typed character,
and is not updating the list of completions half the time.

Previously, interday learning cards and reviews were gathered at the
same time in v3, with the review limit being applied to both of them. The
order cards were gathered in would change the ratio of gathered learning
cards and reviews, but as they were displayed together in a single count,
a changing ratio was not apparent, and no special handling was required
by the deck tree code.
Showing interday learning cards in the learning count, while still
applying a review limit to them, makes things more complicated, as
a changing ratio will result in different counts. The deck tree code
is not able to know which order cards will appear in, so without changes,
we would have had a situation where the deck list may show different counts
to those seen when clicking on a deck.
One way to solve this would have been to introduce a separate limit for
interday learning cards. But this would have meant users needed to
juggle two different limits, instead of having a single one that controls
total number of (non-intraday) cards shown.
Instead, the scheduler now fetches interday cards prior to reviews -
the rationale for that order is that learning cards tend to be more
fragile/urgent than reviews. The option to show learning cards
before/after/mixed with reviews still exists, but it applies only after
cards have been capped to the daily limit.
To ensure the deck tree code matches the counts the scheduler gives,
it too applies limits to interday learning cards first, and reviews
afterwards.
Interday learning cards are now counted in the learning count again,
and are no longer subject to the daily review limit.
The thinking behind the original change was that interday learning cards
are scheduled more like reviews, and counting them in the review count
would allow the learning count to focus on intraday learning - the red
number reflecting the fact that they are the most fragile memories. And
counting them together made it practical to apply the review limit
to both at once.
Since the release, there have been a number of users expecting to see
interday learning cards included in the learning count (the latest being
https://forums.ankiweb.net/t/feedback-and-a-feature-adjustment-request-for-2-1-45/12308),
and a good argument can be made for that too - they are, after all, listed
in the learning steps, and do tend to be harder than reviews. Short of
introducing another count to keep track of interday and intraday learning
separately, moving back to the old behaviour seems like the best move.
This also means it is not really practical to apply the review limit to
interday learning cards anymore, as the limit would be split between two
different numbers, and how much each number is capped would depend on
the order cards are introduced. The scheduler could figure this out, but
the deck list code does not know card order, and would need significant
changes to be able to produce numbers that matched the scheduler. And
even if we ignore implementation complexities, I think it would be more
difficult for users to reason about - the influence of the review limit
on new cards is confusing enough as it is.
Multiple configs with the same inner id would lead to errors like the
following when trying to open the collection:
DeckConfigInner.interval_multiplier: invalid wire type: StartGroup (expected ThirtyTwoBit)
This makes the review backlog case more expensive, since we end up
shuffling items outside the daily limit, but for the common case it's
about the same speed, and it means we don't need two separate sorting
steps. New cards remain handled the same way, since a backlog
is common there.
Also ensures that interday learning cards honor the deck sorting, and
that the non-default sort orders shuffle at the end.
- The "unbury deck" option was broken, as it was ignoring child
decks. It would be nice if we could use active_decks instead, but
plugging that into the old scheduler without breaking undo seems a bit
tricky.
- Remove the implicit From impl for decks, so we need to be forced to
think about whether we want child decks or not.
- Daily limits are no longer inherited - each deck limits its own
cards, and the selected deck enforces a maximum limit.
- Fetching of review cards now uses a single query, and sorts in advance.
In collections with a large number of overdue cards and decks, this is
faster than iterating over each deck in turn.
- Include interday learning count in review count & review limit, and
allow them to be buried.
- Warn when parent review limit is lower than child deck in deck options.
- Cap the new card limit to the review limit.
- Add option to control whether new card fetching short-circuits.
- split new card fetch order and subsequent sort order; use latter
when building queues
- default to spacing siblings when burying is off, with options to
show each sibling in turn, and shuffle the fetched cards
The bury new/review flags are now pulled from each card's home deck,
instead of using a global setting that had not been hooked up. This
unfortunately means we need to fetch the map of all decks up front, as
we need to be able to look up a deck configuration for cards that are
in filtered decks.
Fixes a "card was modified" error caused by cards being buried during
review, when they weren't removed up-front.
