[release/6.0] Don't create multiple large files at the same time #63032
Conversation
* move existing large file tests into a separate type (no code changes) * don't run the large file tests in parallel * use FileOptions.DeleteOnClose to ensure that each test removes it's own file use single large file to test File.ReadAllBytes and ile.ReadAllBytesAsync for both limits

we don't actually need this since we already have the same one here which you can include instead: https://github.com/dotnet/runtime/blob/release/6.0/src/libraries/Common/tests/System/Xml/DisableParallelization.cs

ah looks like it is already that way in main, you'll need to include the file in the .csproj so it works:

File src\libraries\Common\tests\TestUtilities\System\DisableParallelization.cs doesn't exists in release/6.0.
I added the class here because that's how we were doing it prior to #62132.

Yeah it was in a different path in release/6.0 (see the linked file in my first comment), but this is just a cosmetic issue so fine if we keep what you have :)

Will need to get rid of this case because it's an edge case that isn't fixed in 6.0; see: #61519.

locked as resolved and limited conversation to collaborators
Backport of #60606 and #62519.
Move tests that create large files (~4 gb) to OuterLoop and disables parallelization to avoid running into out of memory and time out errors.
Customer Impact
None, this is required to have a clean CI in 6.0 branch.
Testing
Changes have been tested in main for a while.
Risk
Low.
