2024-08-30libstore: print dependency errors from DerivationGoaleldritch horrors
this is not ideal, but it's better than having this stuck in the worker loop itself. setting ex on all failing goals is not problematic because only toplevel goals can ever be observable, all the others are ignored. notably only derivation goals ever set `ex`, substitution goals do not.

2024-08-30libstore: hide Worker goal factory methodseldritch horrors
this doesn't serve a great purpose yet except to confine construction of goals to the stack frame of Worker::run() and its child frames. we don't need this yet (and the goal constructors remain fully visible), but in a future change that fully removes the current worker loop we'll need some way of knowing which goals are top-level goals without passing the goals themselves around. once that's possible we can remove visible goals as a concept and rely on build result futures and a scheduler built upon them Change-Id: Ia73cdeffcfb9ba1ce9d69b702dc0bc637a4c4ce6
2024-08-30libstore: add "is dependency" info to goaleldritch horrors
whether goal errors are reported via the `ex` member or just printed to the log depends on whether the goal is a toplevel goal or a dependency. if goals are aware of this themselves we can move error printing out of the worker loop, and since a running worker can only be used by running goals it's totally sufficient to keep a `Worker::running` flag for this Change-Id: I6b5cbe6eccee1afa5fde80653c4b968554ddd16f

2024-08-28tree-wide: shuffle headers around for about 30s compile timeJade Lovelace
This didn't really feel so worth it afterwards, but I did untangle a bunch of stuff that should not have been tangled. The general gist of this change is that variant bullshit was causing a bunch of compile time, and it seems like the only way to deal with variant induced compile time is to keep variant types out of headers. Explicit template instantiation seems to do nothing for them. I also seem to have gotten some back-end time improvement from explicitly instantiating regex, but I don't know why. There is no corresponding front-end time improvement from it: regex is still at the top of the sinners list. **** Templates that took longest to instantiate: 15231 ms: std::basic_regex<char>::_M_compile (28 times, avg 543 ms) 15066 ms: std::__detail::_Compiler<std::regex_traits<char>>::_Compiler (28 times, avg 538 ms) 12571 ms: std::__detail::_Compiler<std::regex_traits<char>>::_M_disjunction (28 times, avg 448 ms) 12454 ms: std::__detail::_Compiler<std::regex_traits<char>>::_M_alternative (28 times, avg 444 ms) 12225 ms: std::__detail::_Compiler<std::regex_traits<char>>::_M_term (28 times, avg 436 ms) 11363 ms: nlohmann::basic_json<>::parse<const char *> (21 times, avg 541 ms) 10628 ms: nlohmann::basic_json<>::basic_json (109 times, avg 97 ms) 10134 ms: std::__detail::_Compiler<std::regex_traits<char>>::_M_atom (28 times, avg 361 ms) Back-end time before messing with the regex: **** Function sets that took longest to compile / optimize: 8076 ms: void boost::io::detail::put<$>(boost::io::detail::put_holder<$> cons...

2024-08-26treewide: fix a bunch of lintsJade Lovelace
Fixes: - Identifiers starting with _ are prohibited - Some driveby header dependency cleaning which wound up with doing some extra fixups. - Fucking C style casts, man. C++ made these 1000% worse by letting you also do memory corruption with them with references. - Remove casts to Expr * where ExprBlackHole is an incomplete type by introducing an explicitly-cast eBlackHoleAddr as Expr *. - An incredibly illegal cast of the text bytes of the StorePath hash into a size_t directly. You can't DO THAT. Replaced with actually parsing the hash so we get 100% of the bits being entropy, then memcpying the start of the hash. If this shows up in a profile we should just make the hash parser faster with a lookup table or something sensible like that. - This horrendous bit of UB which I thankfully slapped a deprecation warning on, built, and it didn't trigger anywhere so it was dead code and I just deleted it. But holy crap you *cannot* do that. inline void mkString(const Symbol & s) { mkString(((const std::string &) s).c_str()); } - Some wrong lints. Lots of wrong macro lints, one wrong suspicious-sizeof lint triggered by the template being instantiated with only pointers, but the calculation being correct for both pointers and not-pointers. - Exceptions in destructors strike again. I tried to catch the exceptions that might actually happen rather than all the exceptions imaginable. We can let the runtime hard-kill it on other exceptions imo.

2024-08-22libexpr: Replace regex engine with boost::regexsugar
This avoids C++'s standard library regexes, which aren't the same across platforms, and have many other issues, like using stack so much that they stack overflow when processing a lot of data. To avoid backwards and forward compatibility issues, regexes are processed using a function converting libstdc++ regexes into Boost regexes, escaping characters that Boost needs to have escaped, and rejecting features that Boost has and libstdc++ doesn't. Related context: - Original failed attempt to use `boost::regex` in CppNix, failed due to boost icu dependency being large (disabling ICU is no longer necessary because linking ICU requires using a different header file, `boost/regex/icu.hpp`): https://github.com/NixOS/nix/pull/3826 - An attempt to use PCRE, rejected due to providing less backwards compatibility with `std::regex` than `boost::regex`: https://github.com/NixOS/nix/pull/7336 - Second attempt to use `boost::regex`, failed due to `}` regex failing to compile (dealt with by writing a wrapper that parses a regular expression and escapes `}` characters): https://github.com/NixOS/nix/pull/7762 Closes #34.

2024-08-21fix: build with meson 1.5 alsoJade Lovelace
nixpkgs delivered us the untimely gift of a meson 1.5 upgrade, which *does* make our lives easier by allowing us to delete wrap generation code, but it does so at the cost of renaming all rust crates in such a way that the wrap logic cannot tolerate the new names on the old meson version 😭. It also means that support burden for this is going to be atrocious until we either give in and vendor meson 1.5 or we make a CI target for it. Neither seems appealing, though the latter is not super absurd for ensuring we don't break nixpkgs unstable. This commit causes meson 1.5 to ignore the .wrap files in subprojects/ entirely (since they have the wrong names lol) and instead use Cargo.lock, so it now hard-depends on our workspace reshuffling improvement. It also deletes the hack that we were using to get the sources of Cargo deps into meson by using a feature that went unnoticed when this code was originally written: MESON_PACKAGE_CACHE_DIR: https://github.com/mesonbuild/meson/blob/8a202de6ec763284cbb7160b9d43d5e7e0703f19/mesonbuild/wrap/wrap.py#L490-L502 Change-Id: I7a28f12fc2812c6ed7537b60bc3025c141a05874

There have been multiple setting types for paths that are supposed to be canonicalised, depending on whether zero or one, one, or any number of paths is to be specified. Naturally, they behaved in slightly different ways in the code. Simplify things by unifying them and removing special behaviour (mainly the "multiple paths type can coerce to boolean" thing).

This check is wrong and would cause the close_range() function being called even when it's not available Change-Id: Ide65b36830e705fe772196c37349873353622761
2024-08-19tests/functional/restricted: Don't use a process substitutionAudrey Dutcher
The <() process substitution syntax doesn't work for this one testcase in bash for FreeBSD. The exact reason for this is unknown, possibly to do with pipe vs file vs fifo EOF behavior. The prior behavior was this test hanging forever, with no children of the bash process. Change-Id: I71822a4b9dea6059b34300568256c5b7848109ac
2024-08-19flake: don't refetch unmodified inputs by recursive followsMaximilian Bosch
Closes #460 I managed to trigger the issue by having the following inputs (shortened): authentik-nix.url = "github:nix-community/authentik-nix"; authentik-nix.inputs.poetry2nix.inputs.nixpkgs.follows = "nixpkgs"; When evaluating this using nix-eval-jobs --flake .#hydraJobs I got the following error: error: cannot update unlocked flake input 'authentik-nix/poetry2nix' in pure mode The issue we have here is that `authentik-nix/poetry2nix` was written into the `overrideMap` which caused Nix to assume it's a new input and tried to refetch it (#460) or errored out in pure mode (nix-eval-jobs / Hydra). The testcase unfortunately only involves checking for the output log and makes sure that something *is* logged on the first fetch so that the test doesn't rot when the logging changes since I didn't manage to trigger the error above with the reproducer from #460. In fact, I only managed to trigger the `cannot update unlocked flake input` error in this context with `nix-eval-jobs`. Change-Id: Ifd00091eec9a0067ed4bb3e5765a15d027328807
