Empty cards become undoable (#3386)
* Empty cards is undoable

If there was a reason for this operation not to be undoable, I can't easily guess it. My main hyposhesis was that the number of deleted card may be too big. But I realized that deleting a deck is undoable and may delete as many note.

As you may know, I realized that only the undoable operations triggered notification in AnkiDroid that we may have to update the UI. And while I just wanted to trigger more notifications, some reviewers thought it would be nicer if the operation were returning a OpChanges. So here it's done. If you would please consider merging it.

I decided to introduce a new string because the closest strings I could find currently are "Empty cards..." and the trailing commas don't seem nice in "undo". And the title, which we may not be able to reuse in all language

* Don't count cards that have already been removed (dae)

Add apkg import/export on backend (#1743)
* Add apkg export on backend

* Filter out missing media-paths at write time

* Make TagMatcher::new() infallible

* Gather export data instead of copying directly

* Revert changes to rslib/src/tags/

* Reuse filename_is_safe/check_filename_safe()

* Accept func to produce MediaIter in export_apkg()

* Only store file folder once in MediaIter

* Use temporary tables for gathering

export_apkg() now accepts a search instead of a deck id. Decks are
gathered according to the matched notes' cards.

* Use schedule_as_new() to reset cards

* ExportData → ExchangeData

* Ignore ascii case when filtering system tags

* search_notes_cards_into_table →

search_cards_of_notes_into_table

* Start on apkg importing on backend

* Fix due dates in days for apkg export

* Refactor import-export/package

- Move media and meta code into appropriate modules.
- Normalize/check for normalization when deserializing media entries.

* Add SafeMediaEntry for deserialized MediaEntries

* Prepare media based on checksums

- Ensure all existing media files are hashed.
- Hash incoming files during preparation to detect conflicts.
- Uniquify names of conflicting files with hash (not notetype id).
- Mark media files as used while importing notes.
- Finally copy used media.

* Handle encoding in `replace_media_refs()`

* Add trait to keep down cow boilerplate

* Add notetypes immediately instaed of preparing

* Move target_col into Context

* Add notes immediately instaed of preparing

* Note id, not guid of conflicting notes

* Add import_decks()

* decks_configs → deck_configs

* Add import_deck_configs()

* Add import_cards(), import_revlog()

* Use dyn instead of generic for media_fn

Otherwise, would have to pass None with type annotation in the default
case.

* Fix signature of import_apkg()

* Fix search_cards_of_notes_into_table()

* Test new functions in text.rs

* Add roundtrip test for apkg (stub)

* Keep source id of imported cards (or skip)

* Keep source ids of imported revlog (or skip)

* Try to keep source ids of imported notes

* Make adding notetype with id undoable

* Wrap apkg import in transaction

* Keep source ids of imported deck configs (or skip)

* Handle card due dates and original due/did

* Fix importing cards/revlog

Card ids are manually uniquified.

* Factor out card importing

* Refactor card and revlog importing

* Factor out card importing

Also handle missing parents .

* Factor out note importing

* Factor out media importing

* Maybe upgrade scheduler of apkg

* Fix parent deck gathering

* Unconditionally import static media

* Fix deck importing edge cases

Test those edge cases, and add some global test helpers.

* Test note importing

* Let import_apkg() take a progress func

* Expand roundtrip apkg test

* Use fat pointer to avoid propogating generics

* Fix progress_fn type

* Expose apkg export/import on backend

* Return note log when importing apkg

* Fix archived collection name on apkg import

* Add CollectionOpWithBackendProgress

* Fix wrong Interrupted Exception being checked

* Add ClosedCollectionOp

* Add note ids to log and strip HTML

* Update progress when checking incoming media too

* Conditionally enable new importing in GUI

* Fix all_checksums() for media import

Entries of deleted files are nulled, not removed.

* Make apkg exporting on backend abortable

* Return number of notes imported from apkg

* Fix exception printing for QueryOp as well

* Add QueryOpWithBackendProgress

Also support backend exporting progress.

* Expose new apkg and colpkg exporting

* Open transaction in insert_data()

Was slowing down exporting by several orders of magnitude.

* Handle zstd-compressed apkg

* Add legacy arg to ExportAnkiPackage

Currently not exposed on the frontend

* Remove unused import in proto file

* Add symlink for typechecking of import_export_pb2

* Avoid kwargs in pb message creation, so typechecking is not lost

Protobuf's behaviour is rather subtle and I had to dig through the docs
to figure it out: set a field on a submessage to automatically assign 
the submessage to the parent, or call SetInParent() to persist a default
version of the field you specified.

* Avoid re-exporting protobuf msgs we only use internally

* Stop after one test failure

mypy often fails much faster than pylint

* Avoid an extra allocation when extracting media checksums

* Update progress after prepare_media() finishes

Otherwise the bulk of the import ends up being shown as "Checked: 0"
in the progress window.

* Show progress of note imports

Note import is the slowest part, so showing progress here makes the UI
feel more responsive.

* Reset filtered decks at import time

Before this change, filtered decks exported with scheduling remained
filtered on import, and maybe_remove_from_filtered_deck() moved cards
into them as their home deck, leading to errors during review.

We may still want to provide a way to preserve filtered decks on import,
but to do that we'll need to ensure we don't rewrite the home decks of
cards, and we'll need to ensure the home decks are included as part of
the import (or give an error if they're not).

https://github.com/ankitects/anki/pull/1743/files#r839346423

* Fix a corner-case where due dates were shifted by a day

This issue existed in the old Python code as well. We need to include
the user's UTC offset in the exported file, or days_elapsed falls back
on the v1 cutoff calculation, which may be a day earlier or later than
the v2 calculation.

* Log conflicting note in remapped nt case

* take_fields() → into_fields()

* Alias `[u8; 20]` with `Sha1Hash`

* Truncate logged fields

* Rework apkg note import tests

- Use macros for more helpful errors.
- Split monolith into unit tests.
- Fix some unknown error with the previous test along the way.
(Was failing after 969484de4388d225c9f17d94534b3ba0094c3568.)

* Fix sorting of imported decks

Also adjust the test, so it fails without the patch. It was only passing
before, because the parent deck happened to come before the
inconsistently capitalised child alphabetically. But we want all parent
decks to be imported before their child decks, so their children can
adopt their capitalisation.

* target[_id]s → existing_card[_id]s

* export_collection_extracting_media() → ...

export_into_collection_file()

* target_already_exists→card_ordinal_already_exists

* Add search_cards_of_notes_into_table.sql

* Imrove type of apkg export selector/limit

* Remove redundant call to mod_schema()

* Parent tooltips to mw

* Fix a crash when truncating note text

String::truncate() is a bit of a footgun, and I've hit this before
too :-)

* Remove ExportLimit in favour of separate classes

* Remove OpWithBackendProgress and ClosedCollectionOp

Backend progress logic is now in ProgressManager. QueryOp can be used
for running on closed collection.

Also fix aborting of colpkg exports, which slipped through in #1817.

* Tidy up import log

* Avoid QDialog.exec()

* Default to excluding scheuling for deck list deck

* Use IncrementalProgress in whole import_export code

* Compare checksums when importing colpkgs

* Avoid registering changes if hashes are not needed

* ImportProgress::Collection → ImportProgress::File

* Make downgrading apkgs depend on meta version

* Generalise IncrementableProgress

And use it in entire import_export code instead.

* Fix type complexity lint

* Take count_map for IncrementableProgress::get_inner

* Replace import/export env with Shift click

* Accept all args from update() for backend progress

* Pass fields of ProgressUpdate explicitly

* Move update_interval into IncrementableProgress

* Outsource incrementing into Incrementor

* Mutate ProgressUpdate in progress_update callback

* Switch import/export legacy toggle to profile setting

Shift would have been nice, but the existing shortcuts complicate things.
If the user triggers an import with ctrl+shift+i, shift is unlikely to
have been released by the time our code runs, meaning the user accidentally
triggers the new code. We could potentially wait a while before bringing
up the dialog, but then we're forced to guess at how long it will take the
user to release the key.

One alternative would be to use alt instead of shift, but then we need to
trigger our shortcut when that key is pressed as well, and it could
potentially cause a conflict with an add-on that already uses that
combination.

* Show extension in export dialog

* Continue to provide separate options for schema 11+18 colpkg export

* Default to colpkg export when using File>Export

* Improve appearance of combo boxes when switching between apkg/colpkg

+ Deal with long deck names

* Convert newlines to spaces when showing fields from import

Ensures each imported note appears on a separate line

* Don't separate total note count from the other summary lines

This may come down to personal preference, but I feel the other counts
are equally as important, and separating them feels like it makes it
a bit easier to ignore them.

* Fix 'deck not normal' error when importing a filtered deck for the 2nd time

* Fix [Identical] being shown on first import

* Revert "Continue to provide separate options for schema 11+18 colpkg export"

This reverts commit 8f0b2c175f.

Will use a different approach

* Move legacy support into a separate exporter option; add to apkg export

* Adjust 'too new' message to also apply to .apkg import case

* Show a better message when attempting to import new apkg into old code

Previously the user could end seeing a message like:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb5 in position 1: invalid start byte

Unfortunately we can't retroactively fix this for older clients.

* Hide legacy support option in older exporting screen

* Reflect change from paths to fnames in type & name

* Make imported decks normal at once

Then skip special casing in update_deck(). Also skip updating
description if new one is empty.

f3e81c8a95 Move custom study tag and limit gathering+saving into the backend
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.

d52c36e920 Make flag changes undoable again
The previous change in 1871b57663 failed
to consider the browser refreshing case, as reported here:
https://forums.ankiweb.net/t/anki-2-1-50-beta-3-4/17501/30

I previously attempted to solve this by having SetFlag skip the queue
rebuild, then mutating the captured mtimes in the queues. That didn't
work correctly when undoing, as the queue mutations weren't recorded.
This approach combines that attempt and the previous change: flag
setting is an undoable operation again, but does not change the card's
modification time, so it can be applied/undone without a queue build
being required. Instead of special-casing flag changes in the review
screen, we now just redraw the flag on changes.card, as any other card
op will have triggered a queue rebuild.

1871b57663 don't put flag changes in the undo queue, and don't bump mtime
This is not ideal, but I struggled to come up with a better solution.

Background:

- The scheduler records the mtime of cards as it's building the queues,
and will throw an error in get_queued_cards() if the card on the DB
has a different mtime. This is to catch bugs - any operation that modifies
cards should be triggering a queue rebuild, or should adjust the queues
appropriately.
- The review screen skips the usual queue rebuild redraw, and directly
updates the flag icon. This is because a rebuild could cause a different
card to appear, or the answer side to switch back to the question side,
neither of which the user expects when they flag a card.

The current behaviour was broken: the queue rebuilding was still happening
on the backend, and the frontend was just failing to reflect it.

I initially tried to special-case Op::SetFlag, having it skip the queue
rebuild, and having set_card_flag() update the mtimes in the active
queue. But those mutations weren't captured by the undo log, so they
didn't get undone when undoing the set flag operation. We could perhaps
work around it by adding a separate undo entry to capture the mutation,
but it started to feel like it would be a pain to maintain moving forward.

By skipping the undo queue and retaining the same mtime, no queue
rebuild is required. Because we're setting usn, the cards will still
sync, but as mtime is not bumped, in the case of a conflict, an older
unsynced change from another client may revert the flag change.

73d9391f64 update undo skipping; exclude deck/tag expand/collapse
Instead of calling a method inside the transaction body, routines
can now pass Op::SkipUndo if they wish the changes to be discarded
at the end of the transaction. The advantage of doing it this way is
that the list of changes can still be returned, allowing the sync
indicator to update immediately.

be994f4102 add support for custom undo steps, and merging multiple actions
Allows add-on authors to define their own label for a group of undoable
operations. For example:

def mark_and_bury(
    *,
    parent: QWidget,
    card_id: CardId,
) -> CollectionOp[OpChanges]:
    def op(col: Collection) -> OpChanges:
        target = col.add_custom_undo_entry("Mark and Bury")
        col.sched.bury_cards([card_id])
        card = col.get_card(card_id)
        col.tags.bulk_add(note_ids=[card.nid], tags="marked")
        return col.merge_undo_entries(target)

    return CollectionOp(parent, op)

The .add_custom_undo_entry() is for adding your own custom actions.
When extending a standard Anki action, instead store `target = 
col.undo_status().last_step` after executing the standard operation.

This started out as a bigger refactor that required a separate
.commit_undoable() call to be run after each operation, instead of
having each operation return changes directly. But that proved to be
somewhat cumbersome in unit tests, and ran the risk of unexpected
behaviour if the caller invoked an operation without remembering to
finalize it.

Updating a deck via protobuf is now exposed on the backend, but not

undo description for free.

This is currently causing an ugly redraw in the browse screen, which

de668441b5 clear_unused_tags and browser redraw improvements
- clear_unused_tags() is now undoable, and returns the number of removed
notes
- add a new mw.query_op() helper for immutable queries
- decouple "freeze/unfreeze ui state" hooks from the "interface update
required" hook, so that the former is fired even on error, and can be
made re-entrant
- use a 'block_updates' flag in Python, instead of setUpdatesEnabled(),
as the latter has the side-effect of preventing child windows like
tooltips from appearing, and forces a full redrawn when updates are
enabled again. The new behaviour leads to the card list blanking out
when a long-running op is running, but in the future if we cache the
cell values we can just display them from the cache instead.
- we were indiscriminately saving the note with saveNow(), due to the
call to saveTags(). Changed so that it only saves when the tags field
is focused.
- drain the "on_done" queue on main before launching a new background
task, to lower the chances of something in on_done making a small query
to the DB and hanging until a long op finishes
- the duplicate check in the editor was executed after the webview loads,
leading to it hanging until the sidebar finishes loading. Run it at
set_note() time instead, so that the editor loads first.
- don't throw an error when a long-running op started with with_progress()
finishes after the window it was launched from has closed
- don't throw an error when the browser is closed before the sidebar
has finished loading

6b0fe4b381 undoable ops now return changes directly; add new *_ops.py files
- Introduced a new transact() method that wraps the return value
in a separate struct that describes the changes that were made.
- Changes are now gathered from the undo log, so we don't need to
guess at what was changed - eg if update_note() is called with identical
note contents, no changes are returned. Card changes will only be set
if cards were actually generated by the update_note() call, and tag
will only be set if a new tag was added.
- mw.perform_op() has been updated to expect the op to return the changes,
or a structure with the changes in it, and it will use them to fire the
change hook, instead of fetching the changes from undo_status(), so there
is no risk of race conditions.
- the various calls to mw.perform_op() have been split into separate
files like card_ops.py. Aside from making the code cleaner, this works
around a rather annoying issue with mypy. Because we run it with
no_strict_optional, mypy is happy to accept an operation that returns None,
despite the type signature saying it requires changes to be returned.
Turning no_strict_optional on for the whole codebase is not practical
at the moment, but we can enable it for individual files.

Still todo:
- The cursor keeps moving back to the start of a field when typing -
we need to ignore the refresh hook when we are the initiator.
- The busy cursor icon should probably be delayed a few hundreds ms.
- Still need to think about a nicer way of handling saveNow()
- op_made_changes(), op_affects_study_queue() might be better embedded
as properties in the object instead

1e849316be more reset refactoring
'card modified' covers the common case where we need to rebuild the
study queue, but is also set when changing the card flags. We want to
avoid a queue rebuild in that case, as it causes UI flicker, and may
result in a different card being shown. Note marking doesn't trigger
a queue build, but still causes flicker, and may return the user back
to the front side when they were looking at the answer.

I still think entity-based change tracking is the simplest in the
common case, but to solve the above, I've introduced an enum describing
the last operation that was taken. This currently is not trying to list
out all possible operations, and just describes the ones we want to
special-case.

Other changes:

- Fire the old 'state_did_reset' hook after an operation is performed,
so legacy code can refresh itself after an operation is performed.
- Fire the new `operation_did_execute` hook when mw.reset() is called,
so that as the UI is updated to the use the new hook, it will still
be able to refresh after legacy code calls mw.reset()
- Update the deck browser, overview and review screens to listen to
the new hook, instead of relying on the main window to call moveToState()
- Add a 'set flag' backend action, so we can distinguish it from a
normal card update.
- Drop the separate added/modified entries in the change list in
favour of a single entry per entity.
- Add typing to mw.state
- Tweak perform_op()
- Convert a few more actions to use perform_op()

112cbe8b59 experiment with finer-scoped reset in perform_op()
Basic proof of concept, where the 'delete note' operation in the
reviewer has been updated to use mw.perform_op(). Instead of manually
calling .reset() afterwards, a summary of the changes is returned as
part of the undo status query, and various parts of the GUI can listen
to gui_hooks.operation_did_execute and decide whether they want to
redraw based on the scope of the changes. This should allow the sidebar
to selectively redraw just the tags area in the future for example.

Currently we're just listing out all possible areas that might be changed;
in the future we could theoretically inspect the specific changes in the
undo log to provide a more accurate report (avoiding refreshing the tags
list when no tags were added for example).

You can test it out by opening the browse screen while studying, and
then deleting the current card - the browser should update to show (deleted)
on the cards due the earlier change.

If going ahead with this, aside from updating all the screens that currently
listen for resets, some thought will be required on how we can integrate
it with legacy code that expects to called when resets are made, and expects
to call .reset() when it makes changes.

Thoughts?
