should it be log.Warn instead, and include more info about the command being run and the name of the function it's coming from ?

That would be a bit of more involved since there is an existing function called log within the package. I can give a nickname to the logger at the import statement but that looks weird and inconsistent with the rest of the package. The plan B is to rename the internal log function with another name, or to migrate all the uses of the log function with the logger's equivalent. But that would be beyond the scope of this PR.

Oops, sorry. I just realized this was the git module and not gitea itself.

Why do you want to remove documentation in those comments ?

Since that is encapsulated into RunInDirTimeoutPipeline and the test won't be exposed to the nuances anymore (which is what I hope for).

t.Fatalf("Testing %d/%d: %v", i, maxLoops, err)
