[wasm] cleanup testing and host support in templates and tests #73785

pavelsavara · 2022-08-11T16:37:17Z

added new module exports dotnet, exit to dotnet.js
exit method is replacement for our internal set_exit_code
dotnet is a builder pattern with following usage

import { dotnet } from './dotnet.js'

dotnet
    .withDiagnosticTracing(false)
    .withApplicationArguments("dotnet", "is", "great!")
    .run()

The builder methods are

    withConfig(config: MonoConfig): DotnetHostBuilder
    withConfigSrc(configSrc: string): DotnetHostBuilder
    withApplicationArguments(...args: string[]): DotnetHostBuilder
    withEnvironmentVariable(name: string, value: string): DotnetHostBuilder
    withEnvironmentVariables(variables: { [i: string]: string; }): DotnetHostBuilder
    withVirtualWorkingDirectory(vfsPath: string): DotnetHostBuilder
    withDiagnosticTracing(enabled: boolean): DotnetHostBuilder
    withDebugging(level: number): DotnetHostBuilder
    create(): Promise<RuntimeAPI>
    run(): Promise<number>

There are also internal methods useful when testing.
withRuntimeOptions, withWaitingForDebugger, withElementOnExit, withConsoleForwarding, withExitCodeLogging and withModuleConfig

changed implementation of stdout flusing on NodeJS, that it would only delay the process.exit if the exit code is 0
updated templates
updated tests
fixed license headers

TODO

update WBT to use withElementOnExit, withConsoleForwarding, withExitCodeLogging as necessary for templates test
Update WasmAppHost to always pass parameters as query string and add withApplicationArgumentFromQuery
INTERNAL.require may not work (WS unit tests)
add readme to the templates
withAsyncNodeJsFlushOnExit as non-public opt-in nodejs flush on exit (enable optionally on windows only tests?)
public API withMainAssembly for setting main assembly name
create should return this.instance once it exists
fix CI build (possibly we may need to move everything to the post.ex)
dotnet.es6.extpost.js requires a change in the SDK

Contributes to #70892
Fixes #71047

src/mono/sample/wasm/browser/main.js

+    const { runtimeBuildInfo, setModuleImports, getAssemblyExports, runMain, getConfig } = await dotnet
+        .withConsoleForwarding()
+        .withElementOnExit()
+        .withModuleConfig({


why are we configuring some things with a literate '.withXxx' api here and then passing in a big config dictionary?

It's just for backward compatibility. We don't allow everything with those with* methods. Also this method is not "public" as it is not in the typescript public definition.

We actually don't need any of those callbacks now. They could be removed from the sample. It's just showing that they are still there and working, in case somebody needs to go low level.

This could be further improved later and it should not block the PR, I think

WebHostBuilder* seems to go with Use* or Configure* rather than With*?

lewing · 2022-08-14T19:31:54Z

The failures here seem to be the linker related problems that are also in main.

lewing · 2022-08-14T23:22:28Z

src/mono/wasm/runtime/dotnet.d.ts

+    withDiagnosticTracing(enabled: boolean): DotnetHostBuilder;
+    withDebugging(level: number): DotnetHostBuilder;
+    withMainAssembly(mainAssemblyName: string): DotnetHostBuilder;
+    withApplicationArgumentsFromQuery(): DotnetHostBuilder;


This seems like it could have an optional string parameter that defaults to "args"
