Anki 25.06 Beta

[cjdduarte]

I really liked the decision to migrate to Python 3.13! Was there any specific factor that weighed more in choosing this moment to make the migration?

By the way, could this change to Python 3.13 impact or delay the release of the stable Anki version, or are you confident about it? I’ll take the opportunity to revisit my addons.

Anki 25.06 Beta

If I change the DR and then go back to the previous one, the estimated workload doesn’t update: @A_Blokee Plus, the “higher this value, …” message flickers when changing to/from the saved DR.

@Keks Is this the same issue?

[A_Blokee]

I’m not sure if this is a problem with my computers drivers but now whenever I start Anki with Vulkan enabled it crashes without even the “Do you want to switch drivers” message. A git bisect found 04996c77 to be the bad commit, specifically d459af8b8 (It’s a big commit so not very helpful).

I would have updated to it much sooner, but had been waiting for PyOxdizer to gain support past 3.10.

The beta testing period should give us an approximate idea of the impact, and as we’re not depending on any post-3.9 functionality yet, it can be backed out if necessary. Aside from add-ons that vendor Python-version-specific extension modules, I suspect it won’t be that impactful. Anki itself required very few changes to support past 3.9. And users that depend on on a specific broken add-on could easily switch their install back to 3.9 by editing .python-version in AnkiProgramFiles.

Run bash tools\run-qt6.6. It won’t work fully on Windows, but you should then be able to use out\pyenv66\scripts\python to run tools\run.py. If it works, it indicates the Qt version change is the issue.

[Sunong2008]

I’m using a card template called Cloze Interactive (which allows revealing clozes sequentially via shortcut keys) and modified the shortcut keys within it.
When the shortcut keys are ← and →, they don’t work, but when set to q and w, they function properly. Could it be that the new version of Anki has blocked the behavior of ← and → in templates?
Moreover, it seems that navigator.clipboard.writeText in another template is no longer functioning either.

[A_Blokee]

Running with ./tools/run-qt6.6 fixes the issue. (I use Linux so I didn’t need to do the extra steps.)

[dae]

How do 6.7 and 6.9 fare? You’ll need to pull down the latest git for them.

[A_Blokee]

6.7 doesn’t work but 6.9 does.

I produced a corrupt collection.anki2 database ~5 years ago which produced DiskFull

25.06b4 changes the error associated with loading this file. Could someone test in the Desktop UI to be sure the functionality is ‘expected’ (probably unchanging from 25.06b1)

Technical Details

The file produced the following when loaded in 25.06b1 and executing create table nums (id int)

error while compiling: "create table nums (id int)": DBError { info: "SqliteFailure(Error { code: DiskFull, extended_code: 13 }, Some(\"database or disk is full\"))", kind: Other }

In 25.06b4, this now outputs:

JsonError { info: "decoding deck config: expected value at line 1 column 1" }

The Android Framework still outputs a SQLiteFullException when accessing the file

In DataGrip (sqlite 3.45.1):

• SQLITE_IOERR_SHORT_READ when accessing col
• SQLITE_CORRUPT when accessing sqlite_stat1
• other tables seem fine

[vaibhav]

Not sure if it is specific to this beta but I am today, for the first time, seeing a weird error message when clicking “Add to Dictionary” in the editor with @Shigeyuki’s Spell Checker add-on.

Edit: I got this when running Anki from Terminal.

Traceback (most recent call last):

ValueError: invalid mode: 'rbU'

Looks like an add-on bug but I never encountered it before.

Also, I think Anki should return an error window like other errors with an option to copy the debug info so that the user doesn’t need to launch Anki in a terminal to get this.

[Shigeyuki]

Thanks for the report, I’ll look into it. Maybe this update will break a lot of add-ons, if you find other add-ons of mine that are broken, or if you find broken add-ons that the author no longer active, feel free to request them to me through this thread.

@Sunong2008

I’m using a card template called Cloze Interactive

It’s more likely a difference in Qt version and WebEngine. You could try with different Qt version - I’ll try to provide instructions on how to do so in the next beta.

@A_Blokee

6.7 doesn’t work but 6.9 does.

That’s good news. I’d like to get at least one stable release out with 6.8 so that we can get an idea of regresions/improvements with a subsequent upgrade to 6.9, but as they have the same min OS versions, it hopefully wouldn’t be disruptive upgrade.

@David

25.06b4 changes the error associated with loading this file. Could someone test in the Desktop UI to be sure the functionality is ‘expected’ (probably unchanging from 25.06b1)

I think it’s more likely changed in b4, as I bumped the rusqlite version, which likely brought in a newer vendored SQLite. They’re probably being more tolerant of this particular corruption than they were previously.

@vaibhav

ValueError: invalid mode: 'rbU'

This appears to have been deprecated since Python 3.3, and the add-on author would have been alerted to this if they’d been following recommended practice: Console Output - Writing Anki Add-ons

Building the standalone sync-server using the instructions

Will be fixed, thanks.

A new beta has been posted: Release 25.06b5 · ankitects/anki · GitHub

Once it’s available for download, I’ll update New online installer/launcher with instructions.

[jcznk]

It seems these issues have re-occurred:

Anki 25.01/02 Beta/RC

Thanks for the beta! On Windows 11, in the Editor, it seems I cannot use the keyboard arrows to navigate the tag bar. Neither left/right (to move between tags or select which tag to edit) nor up/down (to choose which tag to insert from Anki’s suggestions) work. However, I can still move left and right within a tag when it is already selected.

As Damien says this was just due to old Python code. I fixed it and uploaded it.

I forgot to add the Qt instructions. I’ve edited the post:

New online installer/launcher

A new beta has been released: Auto-update If you start Anki, you’ll notice nothing has changed, because update checks do not happen on every run. To simulate what happens after agreeing to an update pop-up, open the debug console and run the following: from aqt.update import update_and_restart as u; u() Or you can remove the pyproject.toml file mentioned below. Switching between versions The standard pyproject.toml that you’ll find in your AnkiProgramFiles folder (see top post) looks like…

Is mpv installed? Does Anki print something when run from a terminal?

[rihiv]

Reinstalling mpv fixed it! Thank you.
