Diagnostic build log not emitting properties anymore?

[jonathanpeppers]

Issue Description

We first noticed this through Maestro bumps:

• [main] Update dependencies from dotnet/installer android#6029
• [release/6.0.1xx-preview6] Update dependencies from dotnet/installer android#6034

We have a unit test that is asserting several MSBuild properties are in the diagnostic MSBuild log:

build.zip

It's looking for text like AndroidSdkBuildToolsVersion = . I see this as parameters to tasks, but that's it.

That's when I noticed I'm seeing env vars in this log but not properties? Did we regress on that? Thanks!

Steps to Reproduce

I think, just build a project with /flp1:LogFile=build.log;Verbosity=diag and look for properties in the file?

Expected Behavior

Properties are in diagnostic build logs.

Actual Behavior

I don't see properties in diagnostic build logs?

Versions & Configurations

.NET 6.0.100-preview.6.21321.13

Attach a binlog

I don't really see properties in here either:

msbuild.zip

From my minimal local testing, this should be fixed in our current build which will flow through soonish. Please let me know if you see this after tomorrow.

(we talked about this offline but commenting here so it's not lost)

I think this is still happening here: dotnet/android#6046

This should be using 67ba2df.

It looks like the fix in #6520 is there:

msbuild/src/Build/BackEnd/Components/Logging/LoggingService.cs

Lines 511 to 530 in 67ba2df

	/// <summary>
	/// Should properties and items be logged on <see cref="ProjectEvaluationFinishedEventArgs"/>
	/// instead of <see cref="ProjectStartedEventArgs"/>?
	/// </summary>
	public bool IncludeEvaluationPropertiesAndItems
	{
	get
	{
	if (_includeEvaluationPropertiesAndItems == null)
	{
	var sinks = _eventSinkDictionary.Values.OfType<EventSourceSink>();
	// .All() on an empty list defaults to true, we want to default to false
	_includeEvaluationPropertiesAndItems = sinks.Any() && sinks.All(sink => sink.IncludeEvaluationPropertiesAndItems);
	}
	return _includeEvaluationPropertiesAndItems ?? false;
	}
	set => _includeEvaluationPropertiesAndItems = value;
	}

But maybe there is still a newer commit we need? Let me know, thanks.

cc @KirillOsenkov in case something jumps out at you here

Could it be something about using /bl and /flp1 at the same time? We are basically doing:

/noconsolelogger "/flp1:LogFile=build.log;Encoding=UTF-8;Verbosity=Diagnostic" /bl

We're doing this in some integration tests, just to capture every possible log. If we hit something like a crash, sometimes it was easier to read the text log.

[KirillOsenkov]

Curious if you play back the binlog, will the properties be there?

[jonathanpeppers]

Replaying the log above & opening it in VS Code, I don't think I see any properties:

dotnet msbuild msbuild.binlog -v:diag | code -

I see the env vars, but not properties:

Environment at start of build:
                   ALLUSERSPROFILE = C:\ProgramData
...

[KirillOsenkov]

mind sending me both the binlog and the original text log?

[jonathanpeppers]

Oh, they're on the issue above, sorry.

[KirillOsenkov]

Wow, the properties are not in the binlog, neither on ProjectStarted nor on ProjectEvaluationFinished.

This is alarming. I'm taking a look.
