This just handles systems (mac) without realpath installed and with a version of bash
that doesn't support &>>. It also trims path information from the benchmark name

* [wasm] Convert MonoString to string without utf8
Previously when converting strings from mono objects to js we used a utf8 intermediate buffer, this change builds the js string from the mono string without an intermediate.

breakpoints (#19134)
Handle the case where the breakpoint request comes in very early before the runtime initialized by deferring resolution until normal runtime init.
|
|
Try to follow CDP ordering constraints by not responding Debugger.enable until
we've fired scriptParsed events for any already loaded assemblies.
Send Debugger.scriptParsed asynchronously as we load assemblies instead of
waiting for them all to load first and fix some of the sequence point processing
to speed up debugger initialization time.
Rework breakpoint request handling by always passing the request to the browser
then storing both the request and the resultant id for use in when any new scripts
are loaded.
Pass any previous breakpoint requests to the new execution context on page reload.

* [wasm][debug] use console.trace instead to init runtime
Using a `debugger` breakpoint in Mono.mono_wasm_runtime_ready has
unfortunate side effects, this changes the logic to use console.trace
and checks the stackTrace when the event is arrives.
* add a console.trace stub to runtime-test.js
* Use console.debug with a magic number instead

* [wasm][debugger] Always pass failed breakpoint requests to target
Originally we had a simple way to detect that breakpoints were
meant for the runtime but that is no longer true. Now if we
can't location a breakpoint we need to pass the request on to the
target so it can make an attempt.
* Fix test byUrl is a logical breakpoint and should not fail

processed incompatibly

Currently, the Mono WebAssembly debug proxy logic is treated as "shared source" with ASP.NET Core. Each time we update by copying the sources from this repo into the ASP.NET Core repo, we need to make some updates to avoid problems. The intention of this PR is to make the updates here at source, so we can simply copy the sources as-is and don't need to update them each time.
The changes are:
Making everything internal, since this is not intended as public API surface for ASP.NET Core developers. It's an internal implementation detail of the framework.
To retain convenience for the ProxyDriver and Mono test code, this PR also adds a simple public entrypoint called DebuggerProxy. This exposes nothing except the ability to connect a debugger proxy instance to a websocket. In the ASP.NET Core code, we'll simply omit this file since it's not needed, but even if we did get it in the future when the proxy feature is published as a package, it would still be fine since it doesn't expose any public API that would be expensive to support and maintain.
Replacing all the Console.WriteLine calls with use of ILogger from the standard Microsoft.Extensions.Logging package, as used by most .NET Core-based application frameworks including ASP.NET Core.
This allows external code to control what happens with log output, what severity levels are filtered in/out, etc. In ProxyDriver and Mono test code, I've configured it to behave just like before: it logs to console, and doesn't filter out anything.
This has the benefit that various bits of commented-out logging code no longer need to be commented out. Instead, when calling the logger.Log* methods, each call site can specify a severity level and then (for example) the filter level could be set to Debug so that all Trace items are filtered out by default.

[wasm][debugger] Fixes to get async method locals
|
|
|
|
Adds a basic set of standalone benchmarks from multiple sources, along with simple infrastructure for running them in mono, netcore and node.js wasm. A couple of them also have original JS versions you can run from a JS shell.
|
|
- async local field names don't start with `<`, surface those
- `this` for the actual async method is in a field named like
`<>4__this`, surface it as the `this` object

.. commands.

.. breakpoints. Chrome tries set the breakpoints from previous sessions
when the debugger starts up. And we set that in mono, if the runtime is
ready.
But in `MonoProxy.RuntimeReady`, we mark the runtime ready *before*
clearing the breakpoints. So, we end up setting the breakpoints, as
asked by chrome debugger, but then subsequently clearing them!
This manifests as previously set breakpoints in managed code not getting
hit, but if we reset the breakpoint manually then it gets hit.

[wasm][debugger] Improve accessing locals

`mono_wasm_get_var_info` didn't correctly reset the `data.cur_frame`
required for `mono_walk_stack_with_ctx`, as the stack is walked
repeatedly to get the variables.

* [wasm][debugger] Store more per session state and force some event ordering
Register a DebugStore and ExecutionContext per session and force some commands
to block on source loading so that scripts are loaded before attempting to use
them. This should populate the sources in vscode-js-debug properly.

* [wasm] Improve locals visualization in the debugger
- improves handling of generic types, null objects, delegates
- improves getting the name for nested types, arrays, generic types
top todos from this:
- Remove arity in "foo`2<int, int>" from the type name
- Convert nested type names from `foo/bar` to `foo.bar`.
* [wasm] Fix scoping for `mono_wasm_add_null_var`
- which caused runtime uncaught exceptions
* [wasm] Fix possible lost exception in GetScopeProperties
- An exception, eg., because of an invalid scope id just ends up
uncaught instead of showing up as a failed Result.
* [wasm] Address review feedback
- Replace `stringify_type` with `mono_type_full_name` which does exactly
the same thing!
* [wasm][debugger] Fixup nested class, and generic type names
```
// Fix up generic names like Foo`2<int, string> to Foo<int, string>
// and nested class names like Foo/Bar to Foo.Bar
```

The linker can completely link away some assemblies, but the rest of the ninja
build still requires them. Previously they were generated by running csc, but
thats too slow, so generate them using Cecil from wasm-tuner.

(#18814)
The Xamarin.Android team prefers that we ship two different `libmonosgen-2.0.so` for each target, e.g. for arm64 we will have with this PR:
* `./sdks/out/android-arm64-v8a-release/lib/libmonosgen-2.0.so`
* `./sdks/out/android-interpreter-arm64-v8a-release/lib/libmonosgen-2.0.so`
As the names indicate one has the interpreter enabled.
This is contrary to what we do for Xamarin.iOS. There, `--enable-minimal=interpreter` has the side-effect that the build will produce a `libmono-ee-interp.dylib` that can be linked next to `libmonosgen-2.0.dylib`. We _could_ do the same for Android, but that would require us to
* Add `--disable-visibility-hidden` to the Android Mono runtime builds. There are concerns however that this will slow down `dlopen (libmonosgen-2.0.so)` on the Xamarin.Android side.
* Do some changes to the interpreter infrastructure, because `--disable-minimal=interpreter` is designed to be used with a cross compiler in mind. For example, we would need a different solution for this: https://github.com/mono/mono/blob/d7e6fcbda82639fd5afe106b0e7a65a2a72a4f63/mono/mini/tramp-arm64.c#L631-L634
