Single Threat Assertions

[MathiasBartl]

Regarding the problems with resize, I thought about making some assertions that hold for single thread use, like f.e. adding a value increses the size by one (dumb example).
Since otherwise there are very few assertions that can be made in multi threted code.
How do I best realize assertions that depend on some flag?

Aren't normal Haskell asserts turned off automatically when compiling with optimization?

[MathiasBartl]

I just want to kind of assertions, one that are checked during every test, and one that are onky checked during single threated tests.

[rrnewton]

Ah well then it sounds like you just need a runtime boolean flag that controls whether the asserts are active -- i.e. passed in as an argument to the function that builds the test suite, or via a Reader monad.

Yes technically its simple, but should be an very usefull idea.
