How to use the latest Pyodide for Pyxel Web #462

kitao · 2023-04-17T22:29:56Z

Since the latest Pyodide supports SDL2, I'd like update Pyxel Web to work with it instead of the modified version, pyodide-sdl2.

Any help is welcome for that.
@pmp-p, I would appreciate it if you could give me some advice.

ryanking13 · 2023-04-20T04:32:15Z

Hello, Pyodide dev here. I made following changes when porting pyxel:

To reduce the size of the Pyodide main module, I only linked JS parts of SDL2 library to Pyodide main module. So you need to link SDL2 to pyxel itself. I added the following RUSTFLAG that links SDL2 when building pyxel:

export RUSTFLAGS="\
  -C link-arg=-sUSE_SDL=2 \
  -C link-arg=-fPIC \
  -C link-arg=-lSDL2 \
"

We added an API: pyodide.canvas.setElement2D(). This API is used to set a canvas to draw on.

let sdl2Canvas = document.createElement("canvas");
sdl2Canvas.id = "canvas";
pyodide.canvas.setCanvas2D(sdl2Canvas);

Handling unwind exception (Pyodide fatal error occurs in Pyxel on WASM #418) is not yet fully resolved. We found that throwing unwind exceptions corrupts the call stack ([Discussion] Handling "unwind" exception pyodide/pyodide#3697). So for now we added an opt-in flag (pyodide._api._skip_unwind_fatal_error) to ignore unwind errors.

pyodide._api_skip_unwind_fatal_error = true

Thank you for your information.
I tried it and wasm-ld: error: unable to find library -lSDL2 error occured.
I'm wondering Emscripten (emsdk) has the library or not.

ryanking13 · 2023-04-23T12:31:18Z

I guess you need to explicitly build SDL2 first with embuilder build sdl2 --pic.

kitao · 2023-04-23T15:37:44Z

@ryanking13 Thank you! It worked.
Now I'm thinking why it doesn't work when I write the same settings in config under .cargo like this:

[target.wasm32-unknown-emscripten]
rustflags = [
    "-C", "link-arg=-sUSE_SDL=2",
    "-C", "link-arg=-fPIC",
    "-C", "link-arg=-lSDL2",
]

Other options like this in the same file works:

[target.aarch64-apple-darwin]
rustflags = [
    "-C", "link-arg=-undefined",
    "-C", "link-arg=dynamic_lookup",
]

ryanking13 · 2023-04-24T01:22:56Z

Hmm, yeah I think I also failed to add those configs to config file so I ended up using RUSTFLAGS env variable. I don't know much about how cargo read the config but maybe that file is ignored?

When I look at the cargo documentation, there's following explanation. Maybe it's relevant?

At present, when being invoked from a workspace, Cargo does not read config files from crates within the workspace.
i.e. if a workspace has two crates in it, named /projects/foo/bar/baz/mylib and /projects/foo/bar/baz/mybin,
and there are Cargo configs at /projects/foo/bar/baz/mylib/.cargo/config.toml and /projects/foo/bar/baz/mybin/.cargo/config.toml,
Cargo does not read those configuration files if it is invoked from the workspace root (/projects/foo/bar/baz/).

kitao · 2023-04-24T06:03:58Z

Thank you for the useful information. In Makefile, actually I use the same commands except the target name. Specifically, I just call maturin build command.
@messense Do you have any idea of this?

messense · 2023-04-24T06:57:54Z

@kitao It's not read by maturin 0.14, but it's implemented in PyO3/maturin#1405, you can try maturin pre-release to test it out: pip install -U --pre maturin.

kitao · 2023-04-24T10:53:41Z

@messense Thank you!
Let me make sure the current situation.
After changing the build system to Maturin, Pyxel's config files in .cargo are not used actually.
But Maturin handled the build options for Python extension for Mac instead of the configs and then Pyxel worked.
And now I added new options for new Pyodide and it didn't work because the config files were ignored in the first place.
Is my understanding correct?

And now I changed Maturin 1.0.0-beta.7, but it seems that the configs are not read.
Is there other correct place for the config files?

kitao · 2023-04-24T10:54:44Z

By the way, thank you for your continued Maturin updates! @messense

messense · 2023-04-24T12:09:57Z

maturin sets RUSTFLAGS env var so cargo ignores .cargo files, this is because cargo prefer RUSTFLAGS over config files.

And now I changed Maturin 1.0.0-beta.7, but it seems that the configs are not read.

maturin 1.0.0 beta versions read .cargo config files and merge with RUSTFLAGS using cargo-config2. I'm not sure why it's not working for you, I'll add some logging in maturin so it can be diagnosed with RUST_LOG=maturin=debug maturin build.

messense · 2023-04-24T12:15:50Z

Actually CARGO_ENCODED_RUSTFLAGS is already printed with RUST_LOG=maturin=debug maturin build, you can check that.

kitao · 2023-04-25T09:11:08Z

@messense
I tried RUST_LOG=maturin=debug maturin build and it seems that CARGO_ENCODED_RUSTFLAGS doesn't refer to .cargo/config of crates.
Is there any possibility that this setting affects it?

[tool.maturin]
manifest-path = "crates/pyxel-extension/Cargo.toml"

messense · 2023-04-25T11:41:52Z

I'm not sure. Do you have a branch that I can try to debug?

kitao · 2023-04-25T11:47:14Z

Now I've pushed the latest test code to the develop brunch.
Config files are under each crates' directory.
And if you type make under the project root, RUST_LOG=maturin=debug maturin build is called.

kitao · 2023-04-25T11:49:24Z

One more thing, you can set up the venv environment by type `. scripts/setup_python_venv'.
But it's not mandatory if your environment meets Pyxel's requirements.txt

Well you can just write maturin==1.0.0b7 in it.

I changed the requirements.txt, but the old version was installed.
Does the appropriate wheel for Mac exist?

Ah sorry, I didn't commit button yet and now I've pushed it.

My mistake. Now the correct version of Maturin is installed.

@messense Thank you.
In the copied directory (not under OneDrive), Maturin referred to the config file correctly though I don't know how to work it under the OneDrive path. Probably its unicode path causes this trouble, but I don't know how to change OneDrive's default system path. In my terminal, it consists of ascii characters, but it is changed into unicode path automatically by OneDrive.

@ryanking13 I've faced an another issue.
After loading the latest Pyxel wheel in JavaScript, some error occurs when a Python code impots Pyxel.

ModuleNotFoundError: The module 'pyxel' is included in the Pyodide distribution, but it is not installed.
You can install it by calling:
  await micropip.install("pyxel") in Python, or
  await pyodide.loadPackage("pyxel") in JavaScript
See https://pyodide.org/en/stable/usage/loading-packages.html for more details.

Is this the result of conflict between the pre-registered Pyxel in Pyodide and the latest Pyxel?

ryanking13 · 2023-04-26T00:38:47Z

Is this the result of conflict between the pre-registered Pyxel in Pyodide and the latest Pyxel?

I don't think so. Is there other error messages showing in browser console?

kitao · 2023-04-26T03:52:41Z

@ryanking13

There's no error on browser console.

Launch Pyxel

And what pyxel.js does is as follows:

async function _loadPyodideAndPyxel(canvas) {
  await _loadScript(NO_SLEEP_URL);
  let noSleep = new NoSleep();
  noSleep.enable();
  await _loadScript(PYODIDE_URL);
  let pyodide = await loadPyodide();
  pyodide._api._skip_unwind_fatal_error = true;
  pyodide.canvas.setCanvas2D(canvas);
  await pyodide.loadPackage(_scriptDir() + PYXEL_WHEEL_PATH);
  let FS = pyodide.FS;
  FS.mkdir(PYXEL_WORKING_DIRECTORY);
  FS.chdir(PYXEL_WORKING_DIRECTORY);
  return pyodide;
}

It just does pyodide.loadPackage(PYXEL_WHEEL) after loadPyodide() and worked with the previous Pyodide.

ryanking13 · 2023-04-26T05:37:49Z

Hmm, okay. Could you share the wheel file so that I can test?

The error was this:

ImportError: dlopen(/Users/takashi/Library/CloudStorage/OneDrive-個人用/projects/pyxel/venv/lib/python3.11/site-packages/pyxel/pyxel_extension.abi3.so, 0x0002): symbol not found in flat namespace '___isPlatformVersionAtLeast'

Extension lib exists but is doesn't satisfy some condition?

You can try this: https://github.com/alexcrichton/curl-rust/pull/283/files

kitao · 2023-04-27T09:46:00Z

@messense Thank you.
I'm wondering why I faces this error now and looking for the simplest solution.

kitao · 2023-04-28T00:10:48Z

@messense
If I restore the version of Maturin to 0.13.7, symbol not found in flat namespace '___isPlatformVersionAtLeast' doesn't occur and Pyxel works on my M2 Mac.
What's the difference of Mac build envirionment between 0.13.7 and 1.0.0b7?

messense · 2023-04-28T02:04:06Z

MACOSX_DEPLOYMENT_TARGET, #431

kitao · 2023-04-28T03:25:14Z

Yes. I had set the targets according to your past advices.
https://github.com/kitao/pyxel/blob/develop/pyproject.toml#L35-L39

I also tried "10.12" for aarch64 but the result was the same though I'm not sure its the proper version.

kitao · 2023-04-28T23:53:13Z

I understood it happened when the version was too old and decided to add build.rs for covering old versions.
Thank you.
