[browser] threads & js cleanup #86278

pavelsavara · 2023-05-15T20:41:18Z

This is just cleanup. There are no intended functional changes.

TimerQueue

renamed SetTimeout to MainThreadScheduleTimer
renamed ReplaceNextSetTimeout to ReplaceNextTimer
renamed TimeoutCallback to TimerHandler
renamed mono_wasm_set_timeout to mono_wasm_main_thread_schedule_timer
renamed mono_set_timeout_exec to mono_wasm_execute_timer
use [UnmanagedCallersOnly] instead of mono_runtime_try_invoke

ThreadPool

renamed QueueCallback to MainThreadScheduleBackgroundJob using mono_main_thread_schedule_background_job
renamed Callback to BackgroundJobHandler
use [UnmanagedCallersOnly] instead of mono_runtime_try_invoke

JSSynchronizationContext

dropped unused RequestPumpCallback
renamed ScheduleBackgroundJob to MainThreadScheduleBackgroundJob using mono_main_thread_schedule_background_job

Jobs

split mono_threads_schedule_background_job into mono_current_thread_schedule_background_job and mono_main_thread_schedule_background_job
made background job queue TLS

MT Debugger

I added stricter assert about usage of legacy interop with MT and could make debugger tests fail more explicitly on it because they still use bind_static_method.

Other

fixed assert for install_sync_context
fixed browser-threads-minimal to pass on Windows
added mono_threads_wasm_async_run_in_target_thread
added mono_bound_thread_schedule_background_job in preparation for next step
more logging in the sample
cleanup in legacy interop, more asserts about threads
moved conv_string to different file
removed unused _get_class_name, _get_type_name, _get_type_aqn methods
added named wrapper Function into mono_wasm_bind_cs_function and mono_wasm_bind_js_function only under Debug build of the runtime. It makes debugging easier because names the exported/imported function are visible on the stack trace.
fixed how config is applied in the worker via normalizeConfig after it arrived by message.

@lambdageek or @kg please have yet another look and approve. I think the only part which needs your attention is change from invoke via mono reflection to invoke via [UnmanagedCallersOnly] with passing fn pointer. I think it would do the right thing about GC regions ?

lambdageek

Mostly LGTM. A couple of nits.

Two things to consider addressing:

The _DataIsAvailable delegate is there to avoid allocating a new delegate object each time
The 25s delay is testing the threadpool worker timeout doesn't kill a worker that has unsettled promise. Changing to 5s changes the test.

src/mono/System.Private.CoreLib/src/System/Threading/ThreadPool.Browser.Mono.cs

-        [DynamicDependency("Callback")]
        [MethodImplAttribute(MethodImplOptions.InternalCall)]
-        private static extern void QueueCallback();
+        internal static extern unsafe void MainThreadScheduleBackgroundJob(void* callback);


nit: It would be nice to collect all of these internal calls that are called inside S.P.C into a single class

I'm not sure that invoking via UnmanagedCallersOnly will transition from one GC mode to another correctly. @lambdageek do you know?

It will work correctly (unless you use CallConvSuppressGCTransition)
