Missing symbols in libcomponentize_py_runtime.so

[hishamhm]

I followed all build steps in the README and they worked succesfully, apart from cargo test --release failing during build on the first try. The error message suggested me to run rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu. When running this then trying cargo test --release again, then the build succeeded, but tests then failed with unresolved symbols in libcomponentize_py_runtime.so, as shown in the log below:

Hope that helps diagnosing! Happy to provide any more info.

Searching around I found this, which might be related? https://github.com/python/cpython/pull/115757

Thanks for reporting this, @hishamhm. I'll try to reproduce it locally and see what the problem is.

Note that this repo isn't really being maintained, and most of the dependencies are quite out-of-date at this point, so I don't recommend doing anything serious with it :)

[dicej]

I was able to reproduce the issue. The Cargo.toml points to an immutable commit of componentize-py, which in turn points to an immutable commit of CPython as a submodule, and we're building with the same fork of wasi-sdk as before, so I'm not sure what could have changed to break the build. I'm going to update both componentize-py and wasi-sdk to see if that helps.

[dicej]

I just pushed an update to the main branch. All the tests are now passing locally for me. Please let me know if you still have issues.

Note that I've updated the instructions in README.md to use a newer wasi-sdk build, as well as to configure and build the Rust fork a bit differently.

@dicej Thank you! I'll do a full rebuild and report here ASAP!

Noted! I just wanted a starting point to be able to play a bit and start getting acquainted with the preview2 stuff. (since clearly there are a lot of moving parts and things under development in the dependencies!) Thank you for the initiative of putting together this repo!

[dicej]

FYI, I accidentally committed some debug lines to server/Cargo.toml earlier and then fixed that, so please pull one more time to make sure you have the latest code.

Hi! Happy to report that I got (most) tests passing!

After your updates I was still getting most tests failing with a "file not found", but I managed to address it by fetching the command test adapter separately like this:

mkdir target
cd target
wget https://github.com/bytecodealliance/wasmtime/releases/download/v18.0.4/wasi_snapshot_preview1.command.wasm
cd ..
export WASI_SOCKETS_TEST_ADAPTER=$(pwd)/target/wasi_snapshot_preview1.command.wasm

(I tried just updating the URL in server/src/lib.rs but that alone didn't work, and using the environment variable did the trick.)

Also, for some reason localhost seems to only match IPv4 on Ubuntu 22.04 (it has ip6-localhost for IPv6), but adding that to my /etc/hosts made the *_name tests pass. I bring this up for the benefit of search of any other Linux users.

The only remaining test failures are a couple of python_redis* tests which fail with ModuleNotFoundError: No module named 'redis'. But with 14 out of 16 passing, that already gives me enough of an environment to start playing with wasi-sockets! Thank you!
