Note regarding the new-api-needs-documentation label:

This serves as a reminder for when your PR is modifying a ref *.cs file and adding/modifying public APIs, please make sure the API implementation in the src *.cs file is documented with triple slash comments, so the PR reviewers can sign off that change.

The current approach doesn't solve the blocking wait in JS interop, which is then throwing the exception for us too.

[20:37:25] fail: MONO_WASM: at System.Threading.Monitor.Wait(Object obj, Int32 millisecondsTimeout)
at System.Threading.ManualResetEventSlim.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken)
at System.Threading.ManualResetEventSlim.Wait()
at System.Runtime.InteropServices.JavaScript.JavaScriptExports.CompleteTask(JSMarshalerArgument* arguments_buffer)
Error: blocking Wait is not supported on the JS interop thread.

We discussed it in chat and agreed on the introduction of a new flag to signal that the wait comes from JS interop code. The flag can be added to the Monitor class and thus simplify the thread JS interop thread detection.

…row-from-blocking-wait

To not mix intree references and source project

This replaces the previous context base and makes it possible to disable throw for blocking calls in JS interop

Quick list of APIs, for which we need to validate that they internally use something we already addressed so far.
Or we need to address them too.

Task - WaitAll, WaitAny
WaitSubsystem - Wait
WaitableObject - .Wait, SatisfyWaitForAll, Wait_Locked
ThreadWaitInfo - .Wait, Sleep,
LowLevelLock - WaitAndAcquire
LowLevelMonitor - Wait, Acquire
LowLevelSpinWaiter - Wait
LowLevelLifoSemaphore - Wait
FileSystemWatcher - WaitForChanged
GC - WaitForFullGCApproach, WaitForFullGCComplete, WaitForPendingFinalizers
CancellationTokenSource - WaitForCallbackToComplete
ManualResetEventSlim - Wait
SemaphoreSlim - Wait
SynchronizationContext - Wait
WaitHandle - WaitOne, WaitAll
ManualResetEventWithAwaiterSupport - Wait
CountdownEvent - Wait
Interop.Sys.LowLevelMonitor_TimedWait & SystemNative_LowLevelMonitor_Wait

I'm sure I missed some places.

radekdoulik · 2024-02-01T07:21:11Z

Lets get this in and I can extend the tests and API coverage in follow up PR.

pavelsavara · 2024-02-01T08:43:22Z

 public static bool Wait(object obj, int millisecondsTimeout)
 {
 ArgumentNullException.ThrowIfNull(obj);
+#if FEATURE_WASM_THREADS


Let's make helper method for this and localize the message.
The method should be "public" but suppressed same like ThrowOnBlockingWaitOnJSInteropThread.
So that we could use it in other places in the runtime.

pavelsavara · 2024-02-01T11:06:27Z

+ var threadFlag = Monitor.ThrowOnBlockingWaitOnJSInteropThread;
+ Monitor.ThrowOnBlockingWaitOnJSInteropThread = false;
 signal.Wait();
+ Monitor.ThrowOnBlockingWaitOnJSInteropThread = threadFlag;


should this be in try-finally ?
could .Wait ever throw ?
@radekdoulik

I'll will change that on my PR #97832

pavelsavara · 2024-02-01T18:52:52Z

This is unrelated.

It was actually related but hiding behind another problem.
This is now throwing PNSE (as it should), but the test was not ready for it.

runtime/src/libraries/System.Runtime.InteropServices.JavaScript/tests/System.Runtime.InteropServices.JavaScript.UnitTests/System/Runtime/InteropServices/JavaScript/WebWorkerTest.cs

Line 88 in 5cee418

blocker.Wait();

I'm fixing it in #97832
