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.

2023-05-25primops: lazy evaluation of replaceStrings replacementspolykernel
The primop `builtins.replaceStrings` currently always strictly evaluates the replacement strings, however time and space are wasted for their computation if the corresponding pattern do not occur in the input string. This commit makes the evaluation of the replacement strings lazy by deferring their evaluation to when the corresponding pattern are matched and memoize the result for efficient retrieval on subsequent matches. The testcases for replaceStrings was updated to check for lazy evaluation of the replacements. A note was also added in the release notes to document the behavior change.
2023-01-29Allow unit test infra to be reused across libs' testsJohn Ericson
This allows using Arbitrary "instances" defined in libstore-tests in libexpr-tests, something we will leverage in a moment.
