Probably a race condition. `.get_row()` is not a reliable check for card
or note existence, because it returns from an outdated cache,
if the backend is currently blocked.
* Add Deleted error and disable all bad browser rows
* Avoid error when opening the browse screen to a card with a missing note (dae)
* In cards mode, a missing note is NotFound, not Deleted (dae)
So we distinguish between referential integrity error, and explicit
deletion.
* Remove redundant try block
* 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)
* Use submodule imports in aqt
* Use submodule imports in pylib
* More submodule imports in pylib
These required removing some direct imports to get rid of import cycles.
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.
