* Preload external css files to prevent flash of unstyled content
This is an implementation of the approach mentioned in the commit
message of 46b85d5.
* Tweak max_age value for css files
Ensure that css preloading works even on a slow PC.
We want to preserve the backend checks, because they may also detect
bugs. So we do the debouncing on the frontend instead, transitioning
into a temporary state until the background op completes.

When we updated to flask 2.0, the default caching time changed to
0. When setting the HTML of a new card side in the DOM, the browser
first removes the existing content (including styling), then sends a
HTTP request to us to check whether the file has changed or not. By the
time the answer has arrived, the browser has repainted without the
styling, and thus we get a flicker.
A side-effect of reverting to flask 1.x behaviour is that external changes
to media files will not be reflected in Anki for an hour, unless Anki
is restarted, or the caches are cleared manually with an add-on. An
alternative approach would be to pre-fetch the css files like we do with
images, but there are other things like fonts to think about as well.

* Add "Show duplicates" to LabelContainer
* Avoid bubbling down the duplicate logic into EditorField
* Move duplicate link into its own slot
to center it between name/description and field-state.
* Revert "Move duplicate link into its own slot"

* Set QT_QPA_PLATFORM for Win on recent Qt versions
Erroneously dropped for Qt 5.15.1+.
* Enable original shortcut to create copy
* minor tweaks to comment to make it clearer (dae)
* Add py3.9 to hooks
This follows examples from efb1ce46d4 I assume the
hooks were missed because those were not considered types but strings.
I did not even try to run pyupgrade and did the change manually, then used bazel format
* remove wildcard import in find.py, and change Any to object (dae)
Kept the favicon, but have reverted the rest, as it unfortunately did
not seem to prevent the issue from occurring.

Fixes#983
This has been a long-standing issue that was infrequent enough on
developer machines that we weren't able to get to the bottom of it before
now. As luck would have it, the new ARM build had just the right timing
for this to occur every few invocations, and I was able to narrow it down
to the call that turns off the cache.
We don't really want the cache, so this is not a great solution. But I
ran into trouble when trying to figure out a better solution:
- Calling setHttpCacheType() earlier (eg immediately after creating the
page) fails.
- It even fails if you attempt to change the setting in the shared
default profile before any webviews are loaded:
```
def setupMainWindow(self) -> None:
QWebEngineProfile.defaultProfile().setHttpCacheType(QWebEngineProfile.HttpCacheType.NoCache)
```
- Creating a profile separately, and passing it into QWebEnginePage()
does work. But it introduces a warning each time a webview is deallocated,
and I fear it may lead to crashes:
```
Release of profile requested but WebEnginePage still not deleted. Expect troubles !
```
I tried various combinations of parents for the profile and page, and
turning web._page into an unretained property, but could not figure it out.
Some Googling pulls up a bunch of other people who seem to have hit similar
issues with PyQt. If anyone has any ideas, they'd be welcome; in the mean
time, I guess we're better off using up some of the user's disk
space than sometimes failing to load.
The profile-in-advance code I tried is below:

This was motivated by the fact that recording was crashing on the native
M1 build. That ended up being mostly a PEBKAC problem - turns out the
Mac Mini has no built-in microphone 🤦.
I still thinks this has some value though - it doesn't crash in such
cases, and probably doesn't suffer from the problem shown in this thread
either:

For now, this is only enabled when running on arm64. If it turns out to
be reliable, it could be offered as an option on amd64 as well.
More pleasant to work with than ObjectiveC, which will help with the
following commit.
Swift libraries weren't added to macOS until 10.14.4, so theme
autodetection will fail on 10.14.0-10.14.3. The Qt6 build will have its
minimum version bumped to 10.14.4; the Qt5 build will remain on 10.13.4.
Bazel's rules_swift doesn't currently support building Swift dylibs, so
we need to invoke swiftc directly via a genrule().
* Update about.py
* Add cqg to list

* Remove unneeded old.note_type() call
Fixes TypeError thrown after deleting a notetype that's currently selected in the editor.
* Handle IndexError on notetype change
Occurs in the Add window when changing the notetype via NotetypeChooser from

- to a notetype with fewer fields than the auto-selected one
* Add return to exception handler
to properly ignore the command.
The packaged builds of 2.1.50 use python -OO, which means our assertion
statements won't be run. This is not an issue for unit tests (as we
don't run them from a packaged build), or for type assertions (which are
added for mypy's benefit), but we do need to ensure that invariant checks
are still run.
* Allow theme change at runtime and add hook
* Save or restore default palette on theme change
* Update aqt widget styles on theme change
* styling fixes
- drop _light_palette, as default_palette serves the same purpose
- save default platform theme, and restore it when switching away
from nightmode
- update macOS light/dark mode on theme switch
- fix unreadable menus on Windows
* update night-mode classes on theme change
This is the easy part - CSS styling that uses standard_css or our
css variables should update automatically. The main remaining issue
is JS code that sets colors based on the theme at the time it's run -
eg the graph code, and the editor.
* switch night mode value on toggle
* expose current theme via a store; switch graphs to use it

Our unpickle_type() was incorrectly ignoring any non-PyQt class when
unpickling, so it was choking on the reference to _codecs.

QLineEdit seems like the best option, as it saves space and motivates users to keep their descriptions concise.

We're getting an enum instead of an int in Qt6
normal/reversed have been renamed to ascending/descending; no add-ons
appear to be using the old versions.
* Alias PyQt5 to PyQt6 on PyQt6 builds
Restores basic compatibility with PyQt5 add-ons
* Register QtCore early to work around sip error
* Monkey-patch unscoped enums that are in use by add-ons back in
Enums whose namespace moved with PyQt6 were determined using the tooling in https://github.com/qutebrowser/qutebrowser/issues/5904
Relevant enums for the Anki add-on ecosystem were found by grepping through all AnkiWeb add-ons and a selection of GitHub-released add-ons.
* Add full Qt.Key namespace
Maintains compatibility with add-ons that allow specifying key bindings via Qt.Key enums
* Reintroduce PyQt6.Qt as an alias for QtCore.Qt
* Alias classes shifted from QtWidgets to QtGui
* Add missing enums
Adds ≈200 enums that were missed during the initial grep
* Map exec_ calls to exec
* Tweak section headers
* Fix QtWebEngineWidgets imports failing due to delayed import
Addesses: "QtWebEngineWidgets must be imported before a QCoreApplication instance is created"
* Register additional aliases for top-level Qt modules
Given how we have had to deal with side-effects when not registering other aliased imports ahead of time, it seems safer to also register the remaining few with sys.modules.
* Handle calls to deprecated PyQt resource API graciously
* Create QtWebEngineWidgets aliases for classes moved to QtWebEngineCore
* Alias QShortcut
* Restore QWebEnginePage.view()
* Alias sip to PyQt6.sip
* Alias QtCore.QRegExp to QtCore.QRegularExpression
* Restructure aqt.qt into package
Pre-requirement for aliasing the PyQt5.Qt namespace correctly.
Should hopefully also make it easier to keep an overview as Qt-compat-related modules were proliferating.
* Properly alias PyQt5.Qt
PyQt5.Qt used to serve as a common namespace for all Qt classes, not just QtCore.Qt.*
While this changes does not make all classes accessible via PyQt5.Qt, it does so for the most important Qt submodules, which should cover most add-on breakages.
* Simplify Qt resource system legacy handling
* Also alias PyQt6.Qt
Covers imports of the form `from PyQt5 import import Qt` (due to previous aliasing of PyQt5 to PyQt6)
* Add missing enums
Better approach to grepping through add-ons yielded additional hits
* Run formatters
* Satisfy pylint
* PEP8 dbproxy.py
* PEP8 errors.py
* PEP8 httpclient.py
* PEP8 lang.py
* PEP8 latex.py
* Add decorator to deprectate key words
* Make replacement for deprecated attribute optional
* Use new helper `_print_replacement_warning()`

* PEP8 rsbackend.py
* PEP8 sound.py
* PEP8 stdmodels.py
* PEP8 storage.py
* PEP8 sync.py
* PEP8 tags.py
* PEP8 template.py
* PEP8 types.py
* Fix DeprecatedNamesMixinForModule
The class methods need to be overridden with instance methods, so every
module has its own dicts.
* Use `# pylint: disable=invalid-name` instead of id
* PEP8 utils.py
* Only decorate `__getattr__` with `@no_type_check`
* Fix mypy issue with snakecase
Importing it from `anki._vendor` raises attribute errors.
* Format
* Remove inheritance of DeprecatedNamesMixin
There's almost no shared code now and overriding classmethods with
instance methods raises mypy issues.
* Fix traceback frames of deprecation warnings
* remove fn/TimedLog (dae)
Neither Anki nor add-ons appear to have been using it
* fix some issues with stringcase use (dae)
- the wheel was depending on the PyPI version instead of our vendored
version
- _vendor:stringcase should not have been listed in the anki py_library.
We already include the sources in py_srcs, and need to refer to them
directly. By listing _vendor:stringcase as well, we were making a
top-level stringcase library available, which would have only worked for
distributing because the wheel definition was also incorrect.
- mypy errors are what caused me to mistakenly add the above - they
were because the type: ignore at the top of stringcase.py was causing
mypy to completely ignore the file, so it was not aware of any attributes
it contained.
