[wasm] improve startup

[pavelsavara]

streaming wasm instantiation, more parallel download of DLLs

and other goodnes seen in Blazor

• new hook downloadResource?: (request: ResourceRequest) => LoadingResource allows Blazor to delegate the details to runtime while keeping the caching responsibility.
• existing config.assets could now have resolvedUrl and pending response. That's blazor could tell us what to load and also provide pending cache promise.
• made emsripten events async, our callbacks are called in correct order and block on previous one before the next is started.
• improved log messages
• load assets into memory as they arrive from network, avoiding memory allocation spike
• run mono_wasm_pre_init_esential also in Blazor loader. This will fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. This will enable new [JSImport] for blazor.
• locateFile is now used for all assets including mono-config.json. I also fixed scriptDirectory detection on all but v8+CJS. Therefore apps could be executed from different folder than is dotnet.js location. Credits to @yamachu
• run init_crypto also on blazor startup sequence

Issue Details

---

• load assemblies into memory synchronously during onRuntimeInitialized because async user postRun run in parallel to each other and therefore can't use loaded assemblies yet. We will do the same in Blazor.
• run mono_wasm_pre_init_esential also in Blazor loader. This will also fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. We will eliminate it from Blazor code.

Threaded sample isn't happy after the merge. I'm investigating

repro steps:

./build.sh --os browser -c Debug /p:WasmEnablePerfTracing=true
cd src/mono/sample/wasm/browser-eventpipe
make CONFIG=Debug clean publish run V=1 MSBUILD_ARGS=/p:MonoDiagnosticsMock=true

[lambdageek]

Update: the fix helps, but there is still a problem.

I think what's happening is that dotnet.worker.js initializes a Module global and passes it to createDotnetRuntime but this Module = instance assignment (https://github.com/emscripten-core/emscripten/blob/940ae7fe759a81c64e0bde0a41eb33655ad496e1/src/worker.js#L156) is never executed

Which might be because createDotnetRuntimedoesn't return a Promise for some reason. That''s the avenue I'm going to explore tonight. returns a promise that is never settled for some reason.

[lambdageek]

Here's what our dotnet.js and dotnet.worker.js look like from this PR, with threading enabled https://gist.github.com/lambdageek/e54206e2e5365e3f3440a4942a303721#file-dotnet-worker-js

[lambdageek]

Ok, so the issue is in this run function in Emscripten. Note that if it's in a pthread, then it doesn't call doRun (or preRun or any of the rest), it calls a different function that's specific to pthreads. In that function it calls readyResolvePromise(Module) but it never calls postRun.

functionrun(args){args=args||arguments_;if(runDependencies>0){return;}if(ENVIRONMENT_IS_PTHREAD){readyPromiseResolve(Module);initRuntime();postMessage({"cmd": "loaded"});return;}preRun();if(runDependencies>0){return;}functiondoRun(){if(calledRun)return;calledRun=true;Module["calledRun"]=true;if(ABORT)return;initRuntime();readyPromiseResolve(Module);if(Module["onRuntimeInitialized"])Module["onRuntimeInitialized"]();postRun();}if(Module["setStatus"]){Module["setStatus"]("Running...");setTimeout(function(){setTimeout(function(){Module["setStatus"]("");},1);doRun();},1);}else{doRun();}}

So when we do

module.ready=module.ready.then(async()=>{// wait for previous stageawaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

Because nothing resolved afterPostRun, module.ready never resolves, and dotnet.worker.js just returns from self.onmessage ("load") without assigning Module = instance and the worker is left in a bad state.

Update it's less misleading to just return from configure_emscripten_startup without doing anything if we're in a pthread worker. The solution, I think is to change module.ready like this:

module.ready=module.ready.then(async()=>{// wait for previous stage// on pthread workers, postRun is never called, so there is nothing to wait forif(!ENVIRONMENT_IS_PTHREAD)awaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

@pavelsavara

With the above change, the diagnostics sample works for me.

Maybe we should just return from configure_emscripten_startup without changing preRun, onRuntimeInitialized, postRun and ready if we're in a worker since it's just misleading and i'm not sure if running any of the other config-based callbacks makes a ton of sense

[lambdageek]

@pavelsavarapavelsavara#3

As follow-up to this PR we should figure out what kind of JS initialization we want to do in pthread workers. the normal callbacks don't fire. i'm not sure if that's ok or if it's leaving some part of our JS state incorrect.

[pavelsavara]

@lambdageek there is alredy condition in initializeImportsAndExports and I used it to exit startup sequence for workers.
That makes it work up to

WASM ERROR Error: System.PlatformNotSupportedException: Operation is not supported on this platform.
at System.Threading.Thread.ThrowIfNoThreadStart(Boolean )
at System.Threading.Thread.Start(Boolean , Boolean )
at System.Threading.Thread.Start()
at Sample.Test.TestMeaning() in C:\Dev\runtime\src\mono\sample\wasm\browser-mt-eventpipe\Program.cs:line 27

Which is I guess some different issue. If the build is green, I will merge as is and we will continue in follow-up PRs.

I noticed on the screenshot that the init_crypto is running multiple times. I think the latest in this PR should not do that anymore.

[pavelsavara]

@lambdageek when I rebuild with /p:WasmEnableThreads=true and not only /p:WasmEnablePerfTracing=true I could start threads :-D

[pavelsavara]

This is release version

This is release version

That's an asssert that we resumed a thread more times than we suspended it. Probably not due to this PR.

streaming wasm instantiation, more parallel download of DLLs

and other goodnes seen in Blazor

• new hook downloadResource?: (request: ResourceRequest) => LoadingResource allows Blazor to delegate the details to runtime while keeping the caching responsibility.
• existing config.assets could now have resolvedUrl and pending response. That's blazor could tell us what to load and also provide pending cache promise.
• made emsripten events async, our callbacks are called in correct order and block on previous one before the next is started.
• improved log messages
• load assets into memory as they arrive from network, avoiding memory allocation spike
• run mono_wasm_pre_init_esential also in Blazor loader. This will fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. This will enable new [JSImport] for blazor.
• locateFile is now used for all assets including mono-config.json. I also fixed scriptDirectory detection on all but v8+CJS. Therefore apps could be executed from different folder than is dotnet.js location. Credits to @yamachu
• run init_crypto also on blazor startup sequence

Issue Details

---

• load assemblies into memory synchronously during onRuntimeInitialized because async user postRun run in parallel to each other and therefore can't use loaded assemblies yet. We will do the same in Blazor.
• run mono_wasm_pre_init_esential also in Blazor loader. This will also fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. We will eliminate it from Blazor code.

Threaded sample isn't happy after the merge. I'm investigating

repro steps:

./build.sh --os browser -c Debug /p:WasmEnablePerfTracing=true
cd src/mono/sample/wasm/browser-eventpipe
make CONFIG=Debug clean publish run V=1 MSBUILD_ARGS=/p:MonoDiagnosticsMock=true

Update: the fix helps, but there is still a problem.

I think what's happening is that dotnet.worker.js initializes a Module global and passes it to createDotnetRuntime but this Module = instance assignment (https://github.com/emscripten-core/emscripten/blob/940ae7fe759a81c64e0bde0a41eb33655ad496e1/src/worker.js#L156) is never executed

Which might be because createDotnetRuntimedoesn't return a Promise for some reason. That''s the avenue I'm going to explore tonight. returns a promise that is never settled for some reason.

[lambdageek]

Here's what our dotnet.js and dotnet.worker.js look like from this PR, with threading enabled https://gist.github.com/lambdageek/e54206e2e5365e3f3440a4942a303721#file-dotnet-worker-js

[lambdageek]

Ok, so the issue is in this run function in Emscripten. Note that if it's in a pthread, then it doesn't call doRun (or preRun or any of the rest), it calls a different function that's specific to pthreads. In that function it calls readyResolvePromise(Module) but it never calls postRun.

functionrun(args){args=args||arguments_;if(runDependencies>0){return;}if(ENVIRONMENT_IS_PTHREAD){readyPromiseResolve(Module);initRuntime();postMessage({"cmd": "loaded"});return;}preRun();if(runDependencies>0){return;}functiondoRun(){if(calledRun)return;calledRun=true;Module["calledRun"]=true;if(ABORT)return;initRuntime();readyPromiseResolve(Module);if(Module["onRuntimeInitialized"])Module["onRuntimeInitialized"]();postRun();}if(Module["setStatus"]){Module["setStatus"]("Running...");setTimeout(function(){setTimeout(function(){Module["setStatus"]("");},1);doRun();},1);}else{doRun();}}

So when we do

module.ready=module.ready.then(async()=>{// wait for previous stageawaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

Because nothing resolved afterPostRun, module.ready never resolves, and dotnet.worker.js just returns from self.onmessage ("load") without assigning Module = instance and the worker is left in a bad state.

Update it's less misleading to just return from configure_emscripten_startup without doing anything if we're in a pthread worker. The solution, I think is to change module.ready like this:

module.ready=module.ready.then(async()=>{// wait for previous stage// on pthread workers, postRun is never called, so there is nothing to wait forif(!ENVIRONMENT_IS_PTHREAD)awaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

@pavelsavara

With the above change, the diagnostics sample works for me.

Maybe we should just return from configure_emscripten_startup without changing preRun, onRuntimeInitialized, postRun and ready if we're in a worker since it's just misleading and i'm not sure if running any of the other config-based callbacks makes a ton of sense

[lambdageek]

@pavelsavarapavelsavara#3

As follow-up to this PR we should figure out what kind of JS initialization we want to do in pthread workers. the normal callbacks don't fire. i'm not sure if that's ok or if it's leaving some part of our JS state incorrect.

[pavelsavara]

@lambdageek there is alredy condition in initializeImportsAndExports and I used it to exit startup sequence for workers.
That makes it work up to

WASM ERROR Error: System.PlatformNotSupportedException: Operation is not supported on this platform.
at System.Threading.Thread.ThrowIfNoThreadStart(Boolean )
at System.Threading.Thread.Start(Boolean , Boolean )
at System.Threading.Thread.Start()
at Sample.Test.TestMeaning() in C:\Dev\runtime\src\mono\sample\wasm\browser-mt-eventpipe\Program.cs:line 27

Which is I guess some different issue. If the build is green, I will merge as is and we will continue in follow-up PRs.

I noticed on the screenshot that the init_crypto is running multiple times. I think the latest in this PR should not do that anymore.

@lambdageek when I rebuild with /p:WasmEnableThreads=true and not only /p:WasmEnablePerfTracing=true I could start threads :-D

This is release version

This is release version

That's an asssert that we resumed a thread more times than we suspended it. Probably not due to this PR.

streaming wasm instantiation, more parallel download of DLLs

and other goodnes seen in Blazor

• new hook downloadResource?: (request: ResourceRequest) => LoadingResource allows Blazor to delegate the details to runtime while keeping the caching responsibility.
• existing config.assets could now have resolvedUrl and pending response. That's blazor could tell us what to load and also provide pending cache promise.
• made emsripten events async, our callbacks are called in correct order and block on previous one before the next is started.
• improved log messages
• load assets into memory as they arrive from network, avoiding memory allocation spike
• run mono_wasm_pre_init_esential also in Blazor loader. This will fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. This will enable new [JSImport] for blazor.
• locateFile is now used for all assets including mono-config.json. I also fixed scriptDirectory detection on all but v8+CJS. Therefore apps could be executed from different folder than is dotnet.js location. Credits to @yamachu
• run init_crypto also on blazor startup sequence

Issue Details

---

• load assemblies into memory synchronously during onRuntimeInitialized because async user postRun run in parallel to each other and therefore can't use loaded assemblies yet. We will do the same in Blazor.
• run mono_wasm_pre_init_esential also in Blazor loader. This will also fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. We will eliminate it from Blazor code.

Threaded sample isn't happy after the merge. I'm investigating

repro steps:

./build.sh --os browser -c Debug /p:WasmEnablePerfTracing=true
cd src/mono/sample/wasm/browser-eventpipe
make CONFIG=Debug clean publish run V=1 MSBUILD_ARGS=/p:MonoDiagnosticsMock=true

[lambdageek]

Update: the fix helps, but there is still a problem.

I think what's happening is that dotnet.worker.js initializes a Module global and passes it to createDotnetRuntime but this Module = instance assignment (https://github.com/emscripten-core/emscripten/blob/940ae7fe759a81c64e0bde0a41eb33655ad496e1/src/worker.js#L156) is never executed

Which might be because createDotnetRuntimedoesn't return a Promise for some reason. That''s the avenue I'm going to explore tonight. returns a promise that is never settled for some reason.

[lambdageek]

Here's what our dotnet.js and dotnet.worker.js look like from this PR, with threading enabled https://gist.github.com/lambdageek/e54206e2e5365e3f3440a4942a303721#file-dotnet-worker-js

[lambdageek]

Ok, so the issue is in this run function in Emscripten. Note that if it's in a pthread, then it doesn't call doRun (or preRun or any of the rest), it calls a different function that's specific to pthreads. In that function it calls readyResolvePromise(Module) but it never calls postRun.

functionrun(args){args=args||arguments_;if(runDependencies>0){return;}if(ENVIRONMENT_IS_PTHREAD){readyPromiseResolve(Module);initRuntime();postMessage({"cmd": "loaded"});return;}preRun();if(runDependencies>0){return;}functiondoRun(){if(calledRun)return;calledRun=true;Module["calledRun"]=true;if(ABORT)return;initRuntime();readyPromiseResolve(Module);if(Module["onRuntimeInitialized"])Module["onRuntimeInitialized"]();postRun();}if(Module["setStatus"]){Module["setStatus"]("Running...");setTimeout(function(){setTimeout(function(){Module["setStatus"]("");},1);doRun();},1);}else{doRun();}}

So when we do

module.ready=module.ready.then(async()=>{// wait for previous stageawaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

Because nothing resolved afterPostRun, module.ready never resolves, and dotnet.worker.js just returns from self.onmessage ("load") without assigning Module = instance and the worker is left in a bad state.

Update it's less misleading to just return from configure_emscripten_startup without doing anything if we're in a pthread worker. The solution, I think is to change module.ready like this:

module.ready=module.ready.then(async()=>{// wait for previous stage// on pthread workers, postRun is never called, so there is nothing to wait forif(!ENVIRONMENT_IS_PTHREAD)awaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

@pavelsavara

With the above change, the diagnostics sample works for me.

Maybe we should just return from configure_emscripten_startup without changing preRun, onRuntimeInitialized, postRun and ready if we're in a worker since it's just misleading and i'm not sure if running any of the other config-based callbacks makes a ton of sense

[lambdageek]

@pavelsavarapavelsavara#3

As follow-up to this PR we should figure out what kind of JS initialization we want to do in pthread workers. the normal callbacks don't fire. i'm not sure if that's ok or if it's leaving some part of our JS state incorrect.

[pavelsavara]

@lambdageek there is alredy condition in initializeImportsAndExports and I used it to exit startup sequence for workers.
That makes it work up to

WASM ERROR Error: System.PlatformNotSupportedException: Operation is not supported on this platform.
at System.Threading.Thread.ThrowIfNoThreadStart(Boolean )
at System.Threading.Thread.Start(Boolean , Boolean )
at System.Threading.Thread.Start()
at Sample.Test.TestMeaning() in C:\Dev\runtime\src\mono\sample\wasm\browser-mt-eventpipe\Program.cs:line 27

Which is I guess some different issue. If the build is green, I will merge as is and we will continue in follow-up PRs.

I noticed on the screenshot that the init_crypto is running multiple times. I think the latest in this PR should not do that anymore.

[pavelsavara]

@lambdageek when I rebuild with /p:WasmEnableThreads=true and not only /p:WasmEnablePerfTracing=true I could start threads :-D

[pavelsavara]

This is release version

This is release version

That's an asssert that we resumed a thread more times than we suspended it. Probably not due to this PR.

streaming wasm instantiation, more parallel download of DLLs

and other goodnes seen in Blazor

• new hook downloadResource?: (request: ResourceRequest) => LoadingResource allows Blazor to delegate the details to runtime while keeping the caching responsibility.
• existing config.assets could now have resolvedUrl and pending response. That's blazor could tell us what to load and also provide pending cache promise.
• made emsripten events async, our callbacks are called in correct order and block on previous one before the next is started.
• improved log messages
• load assets into memory as they arrive from network, avoiding memory allocation spike
• run mono_wasm_pre_init_esential also in Blazor loader. This will fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. This will enable new [JSImport] for blazor.
• locateFile is now used for all assets including mono-config.json. I also fixed scriptDirectory detection on all but v8+CJS. Therefore apps could be executed from different folder than is dotnet.js location. Credits to @yamachu
• run init_crypto also on blazor startup sequence

Issue Details

---

• load assemblies into memory synchronously during onRuntimeInitialized because async user postRun run in parallel to each other and therefore can't use loaded assemblies yet. We will do the same in Blazor.
• run mono_wasm_pre_init_esential also in Blazor loader. This will also fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. We will eliminate it from Blazor code.

Threaded sample isn't happy after the merge. I'm investigating

repro steps:

./build.sh --os browser -c Debug /p:WasmEnablePerfTracing=true
cd src/mono/sample/wasm/browser-eventpipe
make CONFIG=Debug clean publish run V=1 MSBUILD_ARGS=/p:MonoDiagnosticsMock=true

[lambdageek]

Update: the fix helps, but there is still a problem.

I think what's happening is that dotnet.worker.js initializes a Module global and passes it to createDotnetRuntime but this Module = instance assignment (https://github.com/emscripten-core/emscripten/blob/940ae7fe759a81c64e0bde0a41eb33655ad496e1/src/worker.js#L156) is never executed

Which might be because createDotnetRuntimedoesn't return a Promise for some reason. That''s the avenue I'm going to explore tonight. returns a promise that is never settled for some reason.

[lambdageek]

Here's what our dotnet.js and dotnet.worker.js look like from this PR, with threading enabled https://gist.github.com/lambdageek/e54206e2e5365e3f3440a4942a303721#file-dotnet-worker-js

[lambdageek]

Ok, so the issue is in this run function in Emscripten. Note that if it's in a pthread, then it doesn't call doRun (or preRun or any of the rest), it calls a different function that's specific to pthreads. In that function it calls readyResolvePromise(Module) but it never calls postRun.

functionrun(args){args=args||arguments_;if(runDependencies>0){return;}if(ENVIRONMENT_IS_PTHREAD){readyPromiseResolve(Module);initRuntime();postMessage({"cmd": "loaded"});return;}preRun();if(runDependencies>0){return;}functiondoRun(){if(calledRun)return;calledRun=true;Module["calledRun"]=true;if(ABORT)return;initRuntime();readyPromiseResolve(Module);if(Module["onRuntimeInitialized"])Module["onRuntimeInitialized"]();postRun();}if(Module["setStatus"]){Module["setStatus"]("Running...");setTimeout(function(){setTimeout(function(){Module["setStatus"]("");},1);doRun();},1);}else{doRun();}}

So when we do

module.ready=module.ready.then(async()=>{// wait for previous stageawaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

Because nothing resolved afterPostRun, module.ready never resolves, and dotnet.worker.js just returns from self.onmessage ("load") without assigning Module = instance and the worker is left in a bad state.

Update it's less misleading to just return from configure_emscripten_startup without doing anything if we're in a pthread worker. The solution, I think is to change module.ready like this:

module.ready=module.ready.then(async()=>{// wait for previous stage// on pthread workers, postRun is never called, so there is nothing to wait forif(!ENVIRONMENT_IS_PTHREAD)awaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

@pavelsavara

With the above change, the diagnostics sample works for me.

Maybe we should just return from configure_emscripten_startup without changing preRun, onRuntimeInitialized, postRun and ready if we're in a worker since it's just misleading and i'm not sure if running any of the other config-based callbacks makes a ton of sense

[lambdageek]

@pavelsavarapavelsavara#3

As follow-up to this PR we should figure out what kind of JS initialization we want to do in pthread workers. the normal callbacks don't fire. i'm not sure if that's ok or if it's leaving some part of our JS state incorrect.

[pavelsavara]

@lambdageek there is alredy condition in initializeImportsAndExports and I used it to exit startup sequence for workers.
That makes it work up to

WASM ERROR Error: System.PlatformNotSupportedException: Operation is not supported on this platform.
at System.Threading.Thread.ThrowIfNoThreadStart(Boolean )
at System.Threading.Thread.Start(Boolean , Boolean )
at System.Threading.Thread.Start()
at Sample.Test.TestMeaning() in C:\Dev\runtime\src\mono\sample\wasm\browser-mt-eventpipe\Program.cs:line 27

Which is I guess some different issue. If the build is green, I will merge as is and we will continue in follow-up PRs.

I noticed on the screenshot that the init_crypto is running multiple times. I think the latest in this PR should not do that anymore.

[pavelsavara]

@lambdageek when I rebuild with /p:WasmEnableThreads=true and not only /p:WasmEnablePerfTracing=true I could start threads :-D

[pavelsavara]

This is release version

This is release version

That's an asssert that we resumed a thread more times than we suspended it. Probably not due to this PR.

streaming wasm instantiation, more parallel download of DLLs

and other goodnes seen in Blazor

• new hook downloadResource?: (request: ResourceRequest) => LoadingResource allows Blazor to delegate the details to runtime while keeping the caching responsibility.
• existing config.assets could now have resolvedUrl and pending response. That's blazor could tell us what to load and also provide pending cache promise.
• made emsripten events async, our callbacks are called in correct order and block on previous one before the next is started.
• improved log messages
• load assets into memory as they arrive from network, avoiding memory allocation spike
• run mono_wasm_pre_init_esential also in Blazor loader. This will fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. This will enable new [JSImport] for blazor.
• locateFile is now used for all assets including mono-config.json. I also fixed scriptDirectory detection on all but v8+CJS. Therefore apps could be executed from different folder than is dotnet.js location. Credits to @yamachu
• run init_crypto also on blazor startup sequence

Issue Details

---

• load assemblies into memory synchronously during onRuntimeInitialized because async user postRun run in parallel to each other and therefore can't use loaded assemblies yet. We will do the same in Blazor.
• run mono_wasm_pre_init_esential also in Blazor loader. This will also fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. We will eliminate it from Blazor code.

Threaded sample isn't happy after the merge. I'm investigating

repro steps:

./build.sh --os browser -c Debug /p:WasmEnablePerfTracing=true
cd src/mono/sample/wasm/browser-eventpipe
make CONFIG=Debug clean publish run V=1 MSBUILD_ARGS=/p:MonoDiagnosticsMock=true

[lambdageek]

Update: the fix helps, but there is still a problem.

I think what's happening is that dotnet.worker.js initializes a Module global and passes it to createDotnetRuntime but this Module = instance assignment (https://github.com/emscripten-core/emscripten/blob/940ae7fe759a81c64e0bde0a41eb33655ad496e1/src/worker.js#L156) is never executed

Which might be because createDotnetRuntimedoesn't return a Promise for some reason. That''s the avenue I'm going to explore tonight. returns a promise that is never settled for some reason.

[lambdageek]

Here's what our dotnet.js and dotnet.worker.js look like from this PR, with threading enabled https://gist.github.com/lambdageek/e54206e2e5365e3f3440a4942a303721#file-dotnet-worker-js

[lambdageek]

Ok, so the issue is in this run function in Emscripten. Note that if it's in a pthread, then it doesn't call doRun (or preRun or any of the rest), it calls a different function that's specific to pthreads. In that function it calls readyResolvePromise(Module) but it never calls postRun.

functionrun(args){args=args||arguments_;if(runDependencies>0){return;}if(ENVIRONMENT_IS_PTHREAD){readyPromiseResolve(Module);initRuntime();postMessage({"cmd": "loaded"});return;}preRun();if(runDependencies>0){return;}functiondoRun(){if(calledRun)return;calledRun=true;Module["calledRun"]=true;if(ABORT)return;initRuntime();readyPromiseResolve(Module);if(Module["onRuntimeInitialized"])Module["onRuntimeInitialized"]();postRun();}if(Module["setStatus"]){Module["setStatus"]("Running...");setTimeout(function(){setTimeout(function(){Module["setStatus"]("");},1);doRun();},1);}else{doRun();}}

So when we do

module.ready=module.ready.then(async()=>{// wait for previous stageawaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

Because nothing resolved afterPostRun, module.ready never resolves, and dotnet.worker.js just returns from self.onmessage ("load") without assigning Module = instance and the worker is left in a bad state.

Update it's less misleading to just return from configure_emscripten_startup without doing anything if we're in a pthread worker. The solution, I think is to change module.ready like this:

module.ready=module.ready.then(async()=>{// wait for previous stage// on pthread workers, postRun is never called, so there is nothing to wait forif(!ENVIRONMENT_IS_PTHREAD)awaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

@pavelsavara

With the above change, the diagnostics sample works for me.

Maybe we should just return from configure_emscripten_startup without changing preRun, onRuntimeInitialized, postRun and ready if we're in a worker since it's just misleading and i'm not sure if running any of the other config-based callbacks makes a ton of sense

[lambdageek]

@pavelsavarapavelsavara#3

As follow-up to this PR we should figure out what kind of JS initialization we want to do in pthread workers. the normal callbacks don't fire. i'm not sure if that's ok or if it's leaving some part of our JS state incorrect.

[pavelsavara]

@lambdageek there is alredy condition in initializeImportsAndExports and I used it to exit startup sequence for workers.
That makes it work up to

WASM ERROR Error: System.PlatformNotSupportedException: Operation is not supported on this platform.
at System.Threading.Thread.ThrowIfNoThreadStart(Boolean )
at System.Threading.Thread.Start(Boolean , Boolean )
at System.Threading.Thread.Start()
at Sample.Test.TestMeaning() in C:\Dev\runtime\src\mono\sample\wasm\browser-mt-eventpipe\Program.cs:line 27

Which is I guess some different issue. If the build is green, I will merge as is and we will continue in follow-up PRs.

I noticed on the screenshot that the init_crypto is running multiple times. I think the latest in this PR should not do that anymore.

[pavelsavara]

@lambdageek when I rebuild with /p:WasmEnableThreads=true and not only /p:WasmEnablePerfTracing=true I could start threads :-D

[pavelsavara]

This is release version

[lambdageek]

This is release version

That's an asssert that we resumed a thread more times than we suspended it. Probably not due to this PR.

streaming wasm instantiation, more parallel download of DLLs

and other goodnes seen in Blazor

• new hook downloadResource?: (request: ResourceRequest) => LoadingResource allows Blazor to delegate the details to runtime while keeping the caching responsibility.
• existing config.assets could now have resolvedUrl and pending response. That's blazor could tell us what to load and also provide pending cache promise.
• made emsripten events async, our callbacks are called in correct order and block on previous one before the next is started.
• improved log messages
• load assets into memory as they arrive from network, avoiding memory allocation spike
• run mono_wasm_pre_init_esential also in Blazor loader. This will fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. This will enable new [JSImport] for blazor.
• locateFile is now used for all assets including mono-config.json. I also fixed scriptDirectory detection on all but v8+CJS. Therefore apps could be executed from different folder than is dotnet.js location. Credits to @yamachu
• run init_crypto also on blazor startup sequence

Issue Details

---

• load assemblies into memory synchronously during onRuntimeInitialized because async user postRun run in parallel to each other and therefore can't use loaded assemblies yet. We will do the same in Blazor.
• run mono_wasm_pre_init_esential also in Blazor loader. This will also fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. We will eliminate it from Blazor code.

Threaded sample isn't happy after the merge. I'm investigating

repro steps:

./build.sh --os browser -c Debug /p:WasmEnablePerfTracing=true
cd src/mono/sample/wasm/browser-eventpipe
make CONFIG=Debug clean publish run V=1 MSBUILD_ARGS=/p:MonoDiagnosticsMock=true

[lambdageek]

Update: the fix helps, but there is still a problem.

I think what's happening is that dotnet.worker.js initializes a Module global and passes it to createDotnetRuntime but this Module = instance assignment (https://github.com/emscripten-core/emscripten/blob/940ae7fe759a81c64e0bde0a41eb33655ad496e1/src/worker.js#L156) is never executed

Which might be because createDotnetRuntimedoesn't return a Promise for some reason. That''s the avenue I'm going to explore tonight. returns a promise that is never settled for some reason.

[lambdageek]

Here's what our dotnet.js and dotnet.worker.js look like from this PR, with threading enabled https://gist.github.com/lambdageek/e54206e2e5365e3f3440a4942a303721#file-dotnet-worker-js

[lambdageek]

Ok, so the issue is in this run function in Emscripten. Note that if it's in a pthread, then it doesn't call doRun (or preRun or any of the rest), it calls a different function that's specific to pthreads. In that function it calls readyResolvePromise(Module) but it never calls postRun.

functionrun(args){args=args||arguments_;if(runDependencies>0){return;}if(ENVIRONMENT_IS_PTHREAD){readyPromiseResolve(Module);initRuntime();postMessage({"cmd": "loaded"});return;}preRun();if(runDependencies>0){return;}functiondoRun(){if(calledRun)return;calledRun=true;Module["calledRun"]=true;if(ABORT)return;initRuntime();readyPromiseResolve(Module);if(Module["onRuntimeInitialized"])Module["onRuntimeInitialized"]();postRun();}if(Module["setStatus"]){Module["setStatus"]("Running...");setTimeout(function(){setTimeout(function(){Module["setStatus"]("");},1);doRun();},1);}else{doRun();}}

So when we do

module.ready=module.ready.then(async()=>{// wait for previous stageawaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

Because nothing resolved afterPostRun, module.ready never resolves, and dotnet.worker.js just returns from self.onmessage ("load") without assigning Module = instance and the worker is left in a bad state.

Update it's less misleading to just return from configure_emscripten_startup without doing anything if we're in a pthread worker. The solution, I think is to change module.ready like this:

module.ready=module.ready.then(async()=>{// wait for previous stage// on pthread workers, postRun is never called, so there is nothing to wait forif(!ENVIRONMENT_IS_PTHREAD)awaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

@pavelsavara

With the above change, the diagnostics sample works for me.

Maybe we should just return from configure_emscripten_startup without changing preRun, onRuntimeInitialized, postRun and ready if we're in a worker since it's just misleading and i'm not sure if running any of the other config-based callbacks makes a ton of sense

[lambdageek]

@pavelsavarapavelsavara#3

As follow-up to this PR we should figure out what kind of JS initialization we want to do in pthread workers. the normal callbacks don't fire. i'm not sure if that's ok or if it's leaving some part of our JS state incorrect.

[pavelsavara]

@lambdageek there is alredy condition in initializeImportsAndExports and I used it to exit startup sequence for workers.
That makes it work up to

WASM ERROR Error: System.PlatformNotSupportedException: Operation is not supported on this platform.
at System.Threading.Thread.ThrowIfNoThreadStart(Boolean )
at System.Threading.Thread.Start(Boolean , Boolean )
at System.Threading.Thread.Start()
at Sample.Test.TestMeaning() in C:\Dev\runtime\src\mono\sample\wasm\browser-mt-eventpipe\Program.cs:line 27

Which is I guess some different issue. If the build is green, I will merge as is and we will continue in follow-up PRs.

I noticed on the screenshot that the init_crypto is running multiple times. I think the latest in this PR should not do that anymore.

[pavelsavara]

@lambdageek when I rebuild with /p:WasmEnableThreads=true and not only /p:WasmEnablePerfTracing=true I could start threads :-D

[pavelsavara]

This is release version

This is release version

That's an asssert that we resumed a thread more times than we suspended it. Probably not due to this PR.

streaming wasm instantiation, more parallel download of DLLs

and other goodnes seen in Blazor

• new hook downloadResource?: (request: ResourceRequest) => LoadingResource allows Blazor to delegate the details to runtime while keeping the caching responsibility.
• existing config.assets could now have resolvedUrl and pending response. That's blazor could tell us what to load and also provide pending cache promise.
• made emsripten events async, our callbacks are called in correct order and block on previous one before the next is started.
• improved log messages
• load assets into memory as they arrive from network, avoiding memory allocation spike
• run mono_wasm_pre_init_esential also in Blazor loader. This will fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. This will enable new [JSImport] for blazor.
• locateFile is now used for all assets including mono-config.json. I also fixed scriptDirectory detection on all but v8+CJS. Therefore apps could be executed from different folder than is dotnet.js location. Credits to @yamachu
• run init_crypto also on blazor startup sequence

Issue Details

---

• load assemblies into memory synchronously during onRuntimeInitialized because async user postRun run in parallel to each other and therefore can't use loaded assemblies yet. We will do the same in Blazor.
• run mono_wasm_pre_init_esential also in Blazor loader. This will also fix subtle crypto for them.
• run mono_wasm_after_runtime_initialized also in Blazor loader. This would do mono_wasm_load_runtime, , mono_wasm_runtime_ready and bindings_lazy_init for them. We will eliminate it from Blazor code.

Threaded sample isn't happy after the merge. I'm investigating

repro steps:

./build.sh --os browser -c Debug /p:WasmEnablePerfTracing=true
cd src/mono/sample/wasm/browser-eventpipe
make CONFIG=Debug clean publish run V=1 MSBUILD_ARGS=/p:MonoDiagnosticsMock=true

Update: the fix helps, but there is still a problem.

I think what's happening is that dotnet.worker.js initializes a Module global and passes it to createDotnetRuntime but this Module = instance assignment (https://github.com/emscripten-core/emscripten/blob/940ae7fe759a81c64e0bde0a41eb33655ad496e1/src/worker.js#L156) is never executed

Which might be because createDotnetRuntimedoesn't return a Promise for some reason. That''s the avenue I'm going to explore tonight. returns a promise that is never settled for some reason.

[lambdageek]

Here's what our dotnet.js and dotnet.worker.js look like from this PR, with threading enabled https://gist.github.com/lambdageek/e54206e2e5365e3f3440a4942a303721#file-dotnet-worker-js

[lambdageek]

Ok, so the issue is in this run function in Emscripten. Note that if it's in a pthread, then it doesn't call doRun (or preRun or any of the rest), it calls a different function that's specific to pthreads. In that function it calls readyResolvePromise(Module) but it never calls postRun.

functionrun(args){args=args||arguments_;if(runDependencies>0){return;}if(ENVIRONMENT_IS_PTHREAD){readyPromiseResolve(Module);initRuntime();postMessage({"cmd": "loaded"});return;}preRun();if(runDependencies>0){return;}functiondoRun(){if(calledRun)return;calledRun=true;Module["calledRun"]=true;if(ABORT)return;initRuntime();readyPromiseResolve(Module);if(Module["onRuntimeInitialized"])Module["onRuntimeInitialized"]();postRun();}if(Module["setStatus"]){Module["setStatus"]("Running...");setTimeout(function(){setTimeout(function(){Module["setStatus"]("");},1);doRun();},1);}else{doRun();}}

So when we do

module.ready=module.ready.then(async()=>{// wait for previous stageawaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

Because nothing resolved afterPostRun, module.ready never resolves, and dotnet.worker.js just returns from self.onmessage ("load") without assigning Module = instance and the worker is left in a bad state.

Update it's less misleading to just return from configure_emscripten_startup without doing anything if we're in a pthread worker. The solution, I think is to change module.ready like this:

module.ready=module.ready.then(async()=>{// wait for previous stage// on pthread workers, postRun is never called, so there is nothing to wait forif(!ENVIRONMENT_IS_PTHREAD)awaitafterPostRun.promise;// - here we resolve the promise returned by createDotnetRuntime exportreturnexportedAPI;// - any code after createDotnetRuntime is executed now});

With the above change, the diagnostics sample works for me.

Maybe we should just return from configure_emscripten_startup without changing preRun, onRuntimeInitialized, postRun and ready if we're in a worker since it's just misleading and i'm not sure if running any of the other config-based callbacks makes a ton of sense

As follow-up to this PR we should figure out what kind of JS initialization we want to do in pthread workers. the normal callbacks don't fire. i'm not sure if that's ok or if it's leaving some part of our JS state incorrect.

@lambdageek there is alredy condition in initializeImportsAndExports and I used it to exit startup sequence for workers.
That makes it work up to

WASM ERROR Error: System.PlatformNotSupportedException: Operation is not supported on this platform.
at System.Threading.Thread.ThrowIfNoThreadStart(Boolean )
at System.Threading.Thread.Start(Boolean , Boolean )
at System.Threading.Thread.Start()
at Sample.Test.TestMeaning() in C:\Dev\runtime\src\mono\sample\wasm\browser-mt-eventpipe\Program.cs:line 27

Which is I guess some different issue. If the build is green, I will merge as is and we will continue in follow-up PRs.

I noticed on the screenshot that the init_crypto is running multiple times. I think the latest in this PR should not do that anymore.

@lambdageek when I rebuild with /p:WasmEnableThreads=true and not only /p:WasmEnablePerfTracing=true I could start threads :-D

That's an asssert that we resumed a thread more times than we suspended it. Probably not due to this PR.
