Exclude System.IO.Compression async tests from wasm #114769

carlossanlop · 2025-04-17T09:55:46Z

The newly added async tests in System.IO.Compression and System.IO.Compression.ZipFile are passing in all platforms and architectures except in the wasm libraries tests. They throw 'PlatformNotSupportedException' with the message 'Cannot wait on monitors on this runtime' which seems to be due to async tests not playing nicely in a single threaded environment.

Because I modified the existing tests so they would run the sync and async code depending on the boolean argument, both sync and async tests are currently failing in those wasm platforms.

The fix would be to split the async tests from the sync tests and either excluding the async tests from wasm or finding a way for them to run without issues in wasm.

Why are the zip file tests ever blocking on monitors? Which tests?

Why are the zip file tests ever blocking on monitors? Which tests?

I see some of them quoted in the issue. This isn't an issue with wasm, it's an issue at a minimum with how the tests are written, e.g.
https://github.com/dotnet/runtime/blob/2e8ea867980da8331e821c0e1cb1c6cf89656ede/src/libraries/System.IO.Compression/tests/ZipArchive/zip_InvalidParametersAndStrangeFiles.cs#L286C35-L286C49
e.g.

doing

MemoryStream stream = PopulateStream().Result

instead of

MemoryStream stream = await PopulateStream();

Oh, that's it. I couldn't find that . Result so I thought it was something else about async code causing this issue. Making that line await should make the failure go away.

I did learn about .Result being a cause for such exception based on this S.O. thread.
