Bump version

Use CSP to block inline JS content in editor (#3939 )
* Revert "Sanitize field content in editor" This reverts commit 1c156905f8. * Use CSP to block inline JS content in editor This blocks inline scripts, scripts in the media folder, and handlers like onclick in the editor. This is nicer than the previous solution - it doesn't make any permanent changes, and leaves other content like SVGs alone. Thanks to Nil Admirari for the suggestion. (cherry picked from commit ddb8573e8d)

- We use the fluent system+code generation for translation.
- New strings should be added to rslib/core/. Ask for the appropriate file if you're not sure.
- Assuming a string addons-you-have-count has been added to addons.ftl, that string is accessible in our different languages as follows:
-  - Python: from aqt.utils import tr; msg = tr.addons_you_have_count(count=3)
-  - TypeScript: import * as tr from "@generated/ftl"; tr.addonsYouHaveCount({count: 3})
-  - Rust: collection.tr.addons_you_have_count(3)
- In Qt .ui files, strings that are marked as translatable will automatically use the registered ftl strings. So a QLabel with a title 'addons_you_have_count' that is marked as translatable will automatically use the translation defined in our addons.ftl file.

-# Claude Code Configuration
-
-## Project Overview
-
-Anki is a spaced repetition flashcard program with a multi-layered architecture. Main components:
-
- Web frontend: Svelte/TypeScript in ts/
- PyQt GUI, which embeds the web components in aqt/
- Python library which wraps our rust Layer (pylib/, with Rust module in pylib/rsbridge)
- Core Rust layer in rslib/
- Protobuf definitions in proto/ that are used by the different layers to
-  talk to each other.
-
-## Building/checking
-
-./check (check.bat) will format the code and run the main build & checks.
-Please do this as a final step before marking a task as completed.
-
-## Quick iteration
-
-During development, you can build/check subsections of our code:
-
- Rust: 'cargo check'
- Python: './tools/dmypy', and if wheel-related, './ninja wheels'
- TypeScript/Svelte: './ninja check:svelte'
-
-Be mindful that some changes (such as modifications to .proto files) may
-need a full build with './check' first.
-
-## Build tooling
-
-'./check' and './ninja' invoke our build system, which is implemented in build/. It takes care of downloading required deps and invoking our build
-steps.
-
-## Translations
-
-ftl/ contains our Fluent translation files. We have scripts in rslib/i18n
-to auto-generate an API for Rust, TypeScript and Python so that our code can
-access the translations in a type-safe manner. Changes should be made to
-ftl/core or ftl/qt. Except for features specific to our Qt interface, prefer
-the core module. When adding new strings, confirm the appropriate ftl file
-first, and try to match the existing style.
-
-## Protobuf and IPC
-
-Our build scripts use the .proto files to define our Rust library's
-non-Rust API. pylib/rsbridge exposes that API, and _backend.py exposes
-snake_case methods for each protobuf RPC that call into the API.
-Similar tooling creates a @generated/backend TypeScript module for
-communicating with the Rust backend (which happens over POST requests).
-
-## Fixing errors
-
-When dealing with build errors or failing tests, invoke 'check' or one
-of the quick iteration commands regularly. This helps verify your changes
-are correct. To locate other instances of a problem, run the check again -
-don't attempt to grep the codebase.
-
-## Ignores
-
-The files in out/ are auto-generated. Mostly you should ignore that folder,
-though you may sometimes find it useful to view out/{pylib/anki,qt/_aqt,ts/lib/generated} when dealing with cross-language communication or our other generated sourcecode.
-
-## Launcher/installer
-
-The code for our launcher is in qt/launcher, with separate code for each
-platform.
-
-## Rust dependencies
-
-Prefer adding to the root workspace, and using dep.workspace = true in the individual Rust project.
-
-## Rust utilities
-
-rslib/{process,io} contain some helpers for file and process operations,
-which provide better error messages/context and some ergonomics. Use them
-when possible.
-
-## Rust error handling
-
-in rslib, use error/mod.rs's AnkiError/Result and snafu. In our other Rust modules, prefer anyhow + additional context where appropriate. Unwrapping
-in build scripts/tests is fine.
-
-## Individual preferences
-
-See @.claude/user.md

-Anki's codebase uses three layers.
-
-1. The web frontend, created in Svelte and typescript,
-2. The Python layer and
-3. The core Rust layer.
-
-Each layer can can makes RPC (Remote Procedure Call) to the layers below it. While it should be avoided, Python can also invoke Typescript functions. The Rust layers never make calls to the other layers. Note that it can make RPC to AnkiWeb and other servers, which is out of scope of this document.
-
-In this document we'll provide examples of bridge between languages, explaining:
-
- where the RPC is declared,
- where it is called (with the appropriate imports) and
- where it is implemented.
-
-Imitating those examples should allow you to make call and create new RPCs.
-
-## Declaring RPCs
-
-Let's consider the method `NewDeck` of `DecksServices`. It's declared in [decks.proto](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/proto/anki/decks.proto#L14) as `rpc NewDeck(generic.Empty) returns (Deck);`. This means this methods takes no argument (technically, an argument containing no information), and returns a [`Deck`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/proto/anki/decks.proto#L54).
-
-Read [protobuf](./protobuf.md) to learn more about how those input and output types are defined.
-
-If the RPC implementation is in Python, it should be declared in the service [frontend.proto](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/proto/anki/frontend.proto#L24C3-L24C66)'s `FrontendService`. RPCs declared in any other services are implemented in Rust.
-
-## Making a Remote Procedure Call
-
-In this section we'll consider how to make Remote Procedure Call (RPC) from languages used in Anki. Languages used for AnkiDroid and AnkiMobile are out of scope of this document.
-
-### Making a RPC from Python
-
-Python can invoke the `NewDeck` method with [`col._backend.new_deck()`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/pylib/anki/decks.py#L168). This python method takes no argument and returns a `Deck` value.
-
-However, most Python code should not call this method directly. Instead it should call [`col.decks.new_deck()`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/pylib/anki/decks.py#L166). Generally speaking, all back-end functions called from Python should be called through a helper method defined in `pylib/anki/`. The `_backend` part is an implementation detail that most callers should ignore. This is especially important because add-ons should expect a relatively stable API independent of the implementation details of the RPC.
-
-### Invoking method from TypeScript
-
-Let's consider the method [`rpc GetCsvMetadata(CsvMetadataRequest) returns (CsvMetadata);`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/proto/anki/import_export.proto#L20) from `ImportExportService`..
-
-It's used in the TypeScript class [`ImportCsvState`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/ts/routes/import-csv/lib.ts#L102), as an asynchronous function. It's argument is a single javascript object, whose keys are as in [`CsvMetadataRequest`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/proto/anki/import_export.proto#L138) and it returns a `CsvMetadata`.
-
-The method was imported with `import { getCsvMetadata } from "@generated/backend";` and the types were imported with `import type { CsvMetadata } from "@generated/anki/import_export_pb";`. Note that it was not necessary to import the input type given that it's simply an untyped javascript object.
-
-## Implementation
-
-Let's now look at implementations of those RPCs.
-
-### Implementation in Rust
-
-The method NewDeck is implemented in Rust's [DecksService](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/rslib/src/decks/service.rs#L21) as `fn new_deck(&mut self) -> error::Result<anki_proto::decks::Deck>`. It should be noted that the method name was changed from Pascal case to snake case, and the rps's argument of type `generic.Empty` is ignored.
-
-### Implementation in Python
-
-Let's consider the implementation of the method [DeckOptionsRequireClose](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/qt/aqt/mediasrv.py#L578). It's defined as `def deck_options_require_close() -> bytes:`. In this case, there should be a returned value. However, it'll be ignored, so returning `b""` is perfectly fine.
-
-Note that the incoming HTTP request is not processed on the main thread. In order to do any work with the GUI, we should call `aqt.mw.taskman.run_on_main`.
-
-## Invoking a TypeScript method from Python
-
-This case should be avoided if possible, as we generally should avoid
-calls to the upper layer. Contrary to the previous cases, we don't use
-protobuf.
-
-### Calling a TS function.
-
-Let's take as Example [`export function getTypedAnswer(): string | null`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/ts/reviewer/index.ts#L35). It's an exported function, and its return type can be encoded in JSON.
-
-It's called in the Reviewer class through [`self.web.evalWithCallback("getTypedAnswer();", self._onTypedAnswer)`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/qt/aqt/reviewer.py#L785). The result is then sent to [`_onTypedAnswer`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/qt/aqt/reviewer.py#L787).
-
-If no return value is needed, `web.eval` would have been sufficient.
-
-### Calling a Svelte method
-
-Let's now consider the case where the method we want to call is implemented in a Svelte library. Let's take as example [`deckOptionsPendingChanges`](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/ts/routes/deck-options/%5BdeckId%5D/%2Bpage.svelte#L17). We define it with:
-
-```js
-globalThis.anki || = {};
-globalThis.anki.methodName = async (): Promise<void>=>{body}
-```
-
-Note that if the function is asynchronous, you can't directly send the
-result to a callback. Instead your function will have to call a post
-method that will be sent to Python or Rust.
-
-This method is called in [deckoptions.py](https://github.com/ankitects/anki/blob/acaeee91fa853e4a7a78dcddbb832d009ec3529a/qt/aqt/deckoptions.py#L68) with `self.web.eval("anki.deckOptionsPendingChanges();"`.

Damien Elmes	bfc87c0427	Use CSP to block inline JS content in editor (#3939 ) * Revert "Sanitize field content in editor" This reverts commit `1c156905f8`. * Use CSP to block inline JS content in editor This blocks inline scripts, scripts in the media folder, and handlers like onclick in the editor. This is nicer than the previous solution - it doesn't make any permanent changes, and leaves other content like SVGs alone. Thanks to Nil Admirari for the suggestion. (cherry picked from commit `ddb8573e8d`)	2025-04-23 16:23:18 +10:00
Aristotelis	e9dfb7a13d	Fix `AnkiWebPage` not being initialized for default web view kinds (e.g. in add-ons) (#3933 ) * add AnkiWebView subclasses for stats, empty cards and find dupes ui * update ui files to use subclassed webviews instead * remove superfluous calls to AnkiWebView.set_kind * Avoid set_kind() race condition in legacy stats webview Replacing the web view is a hacky workaround, but likely a reasonable compromise for a legacy view that we do not want to maintain a separate Qt form for. * Slightly refactor AnkiWebView subclass creation and tweak inline comment + Extend create_ankiwebview_subclass() with the ability to set any init time AnkiWebView argument + Introduce some nice-to-haves in terms of static type checking support and IDE autocompletion + Mark helper function as private to discourage add-on use * Drop `AnkiWebView.set_kind` completely There no longer is an Anki-internal use case for changing the web view kind after initializing a web view, and add-ons almost certainly do not have any use for it either. Given that setting the kind after web view construction can lead to known race conditions with `domDone` signals, we should remove this method to discourage uses like this in both Anki code and add-on consumers. There currenty only seems to be one add-on calling `set_kind()`, so this seem like a justifiable API change. --------- Co-authored-by: llama <100429699+iamllama@users.noreply.github.com> (cherry picked from commit `5b0f371791`)	2025-04-23 16:23:02 +10:00

Damien Elmes	8d9c8c91b5	Check collection size when syncing Currently we only check the size on a one-way sync, allowing users to bypass the limits by incrementally syncing a lot of material. To prevent this: - The server now checks if the collection is already oversize, and forces a one-way sync if it is - The client checks if the local collection is oversize and refuses to proceed, so they don't waste time uploading material that will likely trigger the limit the next time they sync.

Aristotelis P	269fb073e9	Inject bridge script when profile set-up skipped Some add-ons fully override AnkiWebPage.__init__ and thus depend on _setupBridge injecting the JS bridge script. With this change we account for these cases, while giving add-ons the opportunity to look for solutions that do not require overriding AnkiWebPage.__init__ completely. (cherry picked from commit `2a97b135ee`)	2025-04-17 11:19:07 +10:00

Damien Elmes	2fc6b72460	Require an auth token for API access We were previously inspecting the referrer, but that is spoofable, and doesn't guard against other processes on the machine. To accomplish this, we use a request interceptor to automatically add an auth token to webviews with the right context. Some related changes were required: - We avoid storing _page, which was leading to leaks & warning on exit - At webview creation (or set_kind() invocation), we assign either an authenticated or unauthenticated web profile. - Some of our screens initialize the AnkiWebView when calling, e.g., aqt.forms.stats.Ui_Dialog(). They then immediately call .set_kind(). This reveals a race condition in our DOM handling code: the webview initialization creates an empty page with the injected script, which causes a domDone signal to be sent back. This signal arrives after we've created another page with .set_kind(), causing our code to think the DOM is ready when it's not. Then when we try to inject the dynamic styling, we get an error, as the DOM is not ready yet. In the absence of better solutions, I've added a hack to set_kind() to deal with this for now. (cherry picked from commit `24bca15fd3`)	2025-04-17 11:17:47 +10:00
Damien Elmes	82f3778340	Sanitize field content in editor The editor already strips script tags from fields, but was allowing through Javascript in things like onclick handlers. We block this now, as the editor context has access to internal APIs that we don't want to expose to untrusted third-party code. (cherry picked from commit `1c156905f8`)	2025-04-17 11:16:57 +10:00
