@jozkee PTAL

[jozkee]

I do agree that the test takes too long, it is already marked as OuterLoop. Is the next step for tests prone to hang to just annotate them with IgnoreForCI?

[akoeplinger]

@jozkee I think a test which takes more than an hour to finish is too long even for OuterLoop.

It should be ran manually only, we have that pattern for other cases already, e.g.

• https://github.com/dotnet/runtime/blob/main/src/libraries/System.IO.FileSystem/tests/ManualTests/ManualTests.cs
• https://github.com/dotnet/runtime/blob/main/src/libraries/System.Console/tests/ManualTests/ManualTests.cs

[akoeplinger]

Hmm though judging from your comment in #77012 (comment) the test took just ~8 minutes on your machine apparently, weird.

[wfurt]

That may depend on the filesystem. Some systems may have /tmp as ramfs. My MacBook is corporate machine and I suspect that AV or some other security functions may be involved. For one, disco encryption is forced by policy.

[akoeplinger]

On CI we're also seeing it time out on Linux and I don't think there's any AV/security thing there though.

[akoeplinger]

I tried running the test locally (after #79899) on my intune'd Mac using Mono and Release config and it took just about 8 minutes too.

[akoeplinger]

I'm also seeing the test not cleaning up the test file right away so it takes more space then necessary even after #79899, sent a PR: #79907
