Extracted repeated logic for clearing FSRS-related fields into a new Card::clear_fsrs_data() method. Updated set_deck and FSRS disabling code paths to use this method for improved code reuse and maintainability.
* Feat/FSRS-6
* update comment
* add decay to Card
* ./ninja fix:minilints
* pass check
* fix NaN in evaluation
* remove console
* decay should fallback to 0.5 when it's None.
* Update SimulatorModal.svelte
* Update a few comments
* Update FSRS decay defaults to use constants for better maintainability and clarity
* Update rslib/src/storage/card/data.rs
* Don't recalculate remaining steps, conditionally
Bug report reproduction steps:
Create a new profile so that everything is set to default.
Create a new card.
Click Good.
Open deck options and empty learning steps. Save.
No go back and put 1m 10m as LS.
Go back to the card and it should show 10m on the Good button.
Check if old_steps is empty and if it is just use remaining
steps for the new_remaining steps. Add test.
* Update contributers
* Format code
* Fix clippy error
* Use more idiomatic imports
* 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)
Caused by using due instead of original_due when card was in learning.
I think the original goal of that code was to ignore the learning timestamp
and show the next review date instead, but it's both simpler and more
intuitive to show the learning date instead.

If we want to be able to factor the desired retention into a sort based
on relative overdueness, having the values accessible on the card makes
things easier.
Will allow user to see a record of difficulty changes, and allows us
to identify reviews that have been done with FSRS vs SM-2, since the
valid range is different.

* Automatically elide empty inputs and outputs to backend methods
* Refactor service generation
Despite the fact that the majority of our Protobuf service methods require
an open collection, they were not accessible with just a Collection
object. To access the methods (e.g. because we haven't gotten around to
exposing the correct API in Collection yet), you had to wrap the collection
in a Backend object, and pay a mutex-acquisition cost for each call, even
if you have exclusive access to the object.
This commit migrates the majority of service methods to the Collection, so
they can now be used directly, and improves the ergonomics a bit at the
same time.
The approach taken:
- The service generation now happens in rslib instead of anki_proto, which
avoids the need for trait constraints and associated types.
- Service methods are assumed to be collection-based by default. Instead of
implementing the service on Backend, we now implement it on Collection, which
means our methods no longer need to use self.with_col(...).
- We automatically generate methods in Backend which use self.with_col() to
delegate to the Collection method.
- For methods that are only appropriate for the backend, we add a flag in
the .proto file. The codegen uses this flag to write the method into a
BackendFooService instead of FooService, which the backend implements.
- The flag can also allows us to define separate implementations for collection
and backend, so we can e.g. skip the collection mutex in the i18n service
while also providing the service on a collection.
* Ensure state mutator runs after card is rendered
* Ensure ease buttons only show when states are ready
* Pass context into states mutator
* Revert queuing of state mutator hook
Now that context data is exposed users shouldn't rely on the question
having been rendered anymore.
* Use callbacks instead of signals and timeout
... to track whether the states mutator ran or failed.
* Make mutator async
* Remove State enum
* Reduce requests and compute seed on backend

Bazel brought a lot of nice things to the table, such as rebuilds based on
content changes instead of modification times, caching of build products,
detection of incorrect build rules via a sandbox, and so on. Rewriting the build
in Bazel was also an opportunity to improve on the Makefile-based build we had
prior, which was pretty poor: most dependencies were external or not pinned, and
the build graph was poorly defined and mostly serialized. It was not uncommon
for fresh checkouts to fail due to floating dependencies, or for things to break
when trying to switch to an older commit.
For day-to-day development, I think Bazel served us reasonably well - we could
generally switch between branches while being confident that builds would be
correct and reasonably fast, and not require full rebuilds (except on Windows,
where the lack of a sandbox and the TS rules would cause build breakages when TS
files were renamed/removed).
Bazel achieves that reliability by defining rules for each programming language
that define how source files should be turned into outputs. For the rules to
work with Bazel's sandboxing approach, they often have to reimplement or
partially bypass the standard tools that each programming language provides. The
Rust rules call Rust's compiler directly for example, instead of using Cargo,
and the Python rules extract each PyPi package into a separate folder that gets
added to sys.path.
These separate language rules allow proper declaration of inputs and outputs,
and offer some advantages such as caching of build products and fine-grained
dependency installation. But they also bring some downsides:
- The rules don't always support use-cases/platforms that the standard language
tools do, meaning they need to be patched to be used. I've had to contribute a
number of patches to the Rust, Python and JS rules to unblock various issues.
- The dependencies we use with each language sometimes make assumptions that do
not hold in Bazel, meaning they either need to be pinned or patched, or the
language rules need to be adjusted to accommodate them.
I was hopeful that after the initial setup work, things would be relatively
smooth-sailing. Unfortunately, that has not proved to be the case. Things
frequently broke when dependencies or the language rules were updated, and I
began to get frustrated at the amount of Anki development time I was instead
spending on build system upkeep. It's now about 2 years since switching to
Bazel, and I think it's time to cut losses, and switch to something else that's
a better fit.
The new build system is based on a small build tool called Ninja, and some
custom Rust code in build/. This means that to build Anki, Bazel is no longer
required, but Ninja and Rust need to be installed on your system. Python and
Node toolchains are automatically downloaded like in Bazel.
This new build system should result in faster builds in some cases:
- Because we're using cargo to build now, Rust builds are able to take advantage
of pipelining and incremental debug builds, which we didn't have with Bazel.
It's also easier to override the default linker on Linux/macOS, which can
further improve speeds.
- External Rust crates are now built with opt=1, which improves performance
of debug builds.
- Esbuild is now used to transpile TypeScript, instead of invoking the TypeScript
compiler. This results in faster builds, by deferring typechecking to test/check
time, and by allowing more work to happen in parallel.
As an example of the differences, when testing with the mold linker on Linux,
adding a new message to tags.proto (which triggers a recompile of the bulk of
the Rust and TypeScript code) results in a compile that goes from about 22s on
Bazel to about 7s in the new system. With the standard linker, it's about 9s.
Some other changes of note:
- Our Rust workspace now uses cargo-hakari to ensure all packages agree on
available features, preventing unnecessary rebuilds.
- pylib/anki is now a PEP420 implicit namespace, avoiding the need to merge
source files and generated files into a single folder for running. By telling
VSCode about the extra search path, code completion now works with generated
files without needing to symlink them into the source folder.
- qt/aqt can't use PEP420 as it's difficult to get rid of aqt/__init__.py.
Instead, the generated files are now placed in a separate _aqt package that's
added to the path.
- ts/lib is now exposed as @tslib, so the source code and generated code can be
provided under the same namespace without a merging step.
- MyPy and PyLint are now invoked once for the entire codebase.
- dprint will be used to format TypeScript/json files in the future instead of
the slower prettier (currently turned off to avoid causing conflicts). It can
automatically defer to prettier when formatting Svelte files.
- svelte-check is now used for typechecking our Svelte code, which revealed a
few typing issues that went undetected with the old system.
- The Jest unit tests now work on Windows as well.
If you're upgrading from Bazel, updated usage instructions are in docs/development.md and docs/build.md. A summary of the changes:
- please remove node_modules and .bazel
- install rustup (https://rustup.rs/)
- install rsync if not already installed (on windows, use pacman - see docs/windows.md)
- install Ninja (unzip from https://github.com/ninja-build/ninja/releases/tag/v1.11.1 and
place on your path, or from your distro/homebrew if it's 1.10+)
- update .vscode/settings.json from .vscode.dist

bug in older Rust version?
* Add card meta for persisting custom scheduling state
* Rename meta -> custom_data
* Enforce limits on size of custom data
Large values will slow down table scans of the cards table, and it's
easier to be strict now and possibly relax things in the future than
the opposite.

* 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.

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.
* Replace Card.data with .original_position
* Use and update original position in v3
* Show original position in card info
* Revert restoring original position for now
* Fix pb card to/from pylib card
* Try original_position as the last pb field
* minor wording tweaks (dae)
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.
Fixes https://forums.ankiweb.net/t/anki-2-1-50-beta-1-2/15608/145
- make sure we set flag in changes when config var changed
- move current deck get/set into backend
- set_config() now returns a bool indicating whether a change was
made, so other operations can be gated off it
- active decks generation is deferred until sched.reset()
So, this is fun. Apparently "DeckId" is considered preferable to the
"DeckID" were were using until now, and the latest clippy will start
warning about it. We could of course disable the warning, but probably
better to bite the bullet and switch to the naming that's generally
considered best.
- 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
'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()
This splits update_card() into separate undoable/non-undoable ops
like the change to notes in b4396b94abdeba3347d30025c5c0240d991006c9
It means that actions get a blanket 'Update Card' description - in the
future we'll probably want to either add specific actions to the backend,
or allow an enum or string to be passed in to describe the op.
Other changes:
- card.flush() can no longer be used to add new cards. Card creation
is only supposed to be done in response to changes in a note's fields,
and this functionality was only exposed because the card generation
hadn't been migrated to the backend at that point. As far as I'm aware,
only Arthur's "copy notes" add-on used this functionality, and that should
be an easy fix - when the new note is added, the associated cards will

be able to get the original Undoable type, which is awkward to do with
a trait object.
