2024-03-31libutil: remove Pool::flushBadeldritch horrors
this was never actually used, and bad design in the first place—why should a bad resource be put back into the idle pool? just drop it. Change-Id: Idab8774bee19dadae0209d404c4fb86dd4aeba1e
2024-03-30libutil: drop Pool resources on exceptional freeeldritch horrors
if a scope owning a resource does not gracefully drop that resource while handling exceptions from deeper down the call stack we should assume the resource is invalid state and drop it. currently it *is* true that such cases do not cause resources to be freed, but thanks to validator misuses this has so far not caused any larger problem.

2023-12-01Move tests to separate directories, and documentJohn Ericson
Today, with the tests inside a `tests` intermingled with the corresponding library's source code, we have a few problems: - We have to be careful that wildcards don't end up with tests being built as part of Nix proper, or test headers being installed as part of Nix proper. - Tests in libraries but not executables is not right: - It means each executable runs the previous unit tests again, because it needs the libraries. - It doesn't work right on Windows, which doesn't want you to load a DLL just for the side global variable . It could be made to work with the dlopen equivalent, but that's gross! This reorg solves these problems. There is a remaining problem which is that sibbling headers (like `hash.hh` the test header vs `hash.hh` the main `libnixutil` header) end up shadowing each other. This PR doesn't solve that. That is left as future work for a future PR.
