2024-08-28 | tree-wide: shuffle headers around for about 30s compile time | Jade 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...

2024-08-26 | treewide: fix a bunch of lints | Jade 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.

2024-08-08 | tree-wide: fix a pile of lints | Jade Lovelace | |
This: - Converts a bunch of C style casts into C++ casts. - Removes some very silly pointer subtraction code (which is no more or less busted on i686 than it began) - Fixes some "technically UB" that never had to be UB in the first place. - Makes finally follow the noexcept status of the inner function. Maybe in the future we should ban the function from not being noexcept, but that is not today. - Makes various locally-used exceptions inherit from std::exception.

2024-08-08 | build: integrate clang-tidy into CI | Jade Lovelace | |
This still has utterly unacceptably bad output format design that I would not inflict on anyone I like, but it *does* now exist, and you *can* find the errors in the log. Future work would obviously be to fix that and integrate the actual errors into Gerrit using codechecker or so.

don't consume a sink, return a source instead. the only reason to not do this is a very slight reduction in dynamic allocations, but since we are going to *at least* do disk io that will not be a lot of overhead anyway Change-Id: Iae2f879ec64c3c3ac1d5310eeb6a85e696d4614a | |||

2023-04-07 | Rename and protect `BufferedSink::write` | Théophane Hufschmitt | |
The `write` name is ambiguous and could lead to some funny bugs like https://github.com/NixOS/nix/pull/8173#issuecomment-1500009480. So rename it to the more explicit `writeUnbuffered`. Besides, this method shouldn't be (and isn't) used outside of the class implementation, so mark it `protected`. This makes it more symetrical to `BufferedSource` which uses a `protected readUnbuffered` method. | |||
