Previously it was Backend's responsibility to store the last progress,
and when calling routines in Collection, one had to construct and pass
in a Fn, which wasn't the most ergonomic. This PR adds the last progress
state to the collection, so that the routines no longer need a separate
progress arg, and makes some other tweaks to improve ergonomics.
ThrottlingProgressHandler has been tweaked so that it now stores the
current state, so that callers don't need to store it separately. When
a long-running routine starts, it calls col.new_progress_handler(),
which automatically initializes the data to defaults, and updates the
shared UI state, so we no longer need to manually update the state at
the start of an operation.
The backend shares the Arc<Mutex<>> with the collection, so it can get
at the current state, and so we can update the state when importing a
backup.
Other tweaks:
- The current Incrementor was awkward to use in the media check, which
uses a single incrementing value across multiple method calls, so I've
added a simpler alternative for such cases. The old incrementor method
has been kept, but implemented directly on ThrottlingProgressHandler.
- The full sync code was passing the progress handler in a complicated
way that may once have been required, but no longer is.
- On the Qt side, timers are now stopped before deletion, or they keep
running for a few seconds.
- I left the ChangeTracker using a closure, as it's used for both importing
and syncing.
A 10ms delay was chosen as it tends to result in the progress window
appearing immediately when clicking into the unfocused window, preventing
another action from being started before the progress window appears.
Closes#1873
* 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.

* 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 8f0b2c175f4794d642823b60414d142a12768441.
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.

* Add progress.single_shot()
* Fix periodic garbage collection
* Properly cleanup mediasync timers
* Revert some replacements with `single_shot()`
These timers shouldn't fire if their widget is destroyed.
* Add timer docs explaining issues and alternatives
* Apply suggestions from code review
* Tweak docstrings
* Fix wrong hook being torn down
* Fix item models not being destroyed
* Add missing gc for FilteredDeckConfigDialog
* Add missing type annotation
* Pass calling widget as parent to QTimer
Implicitly passing `self.mw` as the parent means that the QTimer won't
get destroyed before quitting the app, which also thwarts garbage
collection of any data captured by a passed closure.
* Make `Editor._links` an instance variable
Browser is inserting a closure into this dict capturing itself. As a class
variable, it won't get destroyed, so neither will the browser.
* Make `Editor._links` funcs take instance again
* Deprecate calling progress.timer() without parent
* show caller location when printing deprecation warning (dae)
The enum changes should work on PyQt 5.x, and are required in PyQt 6.x.
They are not supported by the PyQt5 typings however, so we need to run
our tests with PyQt6.
This adds Python 3.9 and 3.10 typing syntax to files that import
attributions from __future___. Python 3.9 should be able to cope with
the 3.10 syntax, but Python 3.8 will no longer work.
On Windows/Mac, install the latest Python 3.9 version from python.org.
There are currently no orjson wheels for Python 3.10 on Windows/Mac,
which will break the build unless you have Rust installed separately.
On Linux, modern distros should have Python 3.9 available already. If
you're on an older distro, you'll need to build Python from source first.
- 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
Setting it straight away causes the cursor to flash on quick operations,
like saving the current note. Delay it for 300ms, which should hopefully
be long enough to not get in the way, but short enough to give indication
that long-running requests are being processed.
For things like updating the deck list, it makes no sense to do it
multiple times at the end of a long operation, and the once/second signal
timer was causing hundreds or thousands of 100ms timers to be created.
https://forums.ankiweb.net/t/anki-memory-usage/3842
Also:
- provide a way for the progress handler to skip the throttling so that
we can ensure progress is updated at the end of a stage
- show 'checking' at the end of full sync
This code was an awful hack to provide some semblance of UI
responsiveness while executing DB statements on the main thread.
Instead, we can just run DB statements in a background thread now,
keeping the UI responsive.
We were previously relying on the DB progress hook to cause the
progress window to display.
Qt's progress dialogs do have built in support for automatically
showing, but it's easier to add a timer than change the existing
code to use it.
Instead, set the busy cursor immediately to give the user feedback,
but defer popup for at least 500ms. This will hopefully address the
white flash in night mode on Windows, and prevent progress dialogs
from rapidly appearing and disappearing for short operations.
