Using arguments: benchmark 'System.Text.Json.Serialization.Tests.ReadJson<Int32>*'

@MihaZupan This didn't work. Is there currently a way to trigger a benchmark job without opening a PR against dotnet/runtime?

I'm trying to validate whether there are still regressions related to dotnet/runtime#112138.

[MihaZupan]

Not from the UI, that's limited to JitDiff right now.
I have controls for it over Discord, started #1428.

The filter fails locally too, due to the character entity references :

The filter 'System.Text.Json.Serialization.Tests.ReadJson<Int32>*' that you have provided returned 0 benchmarks.

From the dotnet/runtime#112138 (comment) issue description:

git clone https://github.com/dotnet/performance.git
python3 .\performance\scripts\benchmarks_ci.py -f net8.0 --filter 'System.Text.Json.Serialization.Tests.ReadJson<Int32>*'

@DrewScoggins Could you please take a look at this perf-autofiling-issues issue description issue?

[DrewScoggins]

Yeah, I will take a look and see why it is not properly displaying.

[xtqqczze]

@DrewScoggins It looks like this issue is still occurring, for example, see dotnet/perf-autofiling-issues#63240:

--filter 'System.Collections.IndexerSet<Int32>*'

Would you be able to confirm if there’s a more appropriate place to track this ongoing problem?

[DrewScoggins]

Thanks for the ping. Got busy on other stuff and hadn't had time to get back around to this. I have a PR up to stop doing the angle bracket encoding when we are inside a code block.
