2024-10-14ssh-ng: better way to keep SSH errors visibleMaximilian Bosch
A better fix than in 104448e75d87d03d2fb0b4ac96d4da72e1dae50d, hence a revert + the fix. It turns out that this commit has the side-effect that when having e.g. `StrictHostKeyChecking=accept-new` for a remote builder, the warnings à la Warning: Permanently added 'builder' (ED25519) to the list of known hosts. actually end up in the derivation's log whereas hostkey verification errors don't, but only in the stderr of the `nix-build` invocation (which was the motivation for the patch). This change writes the stderr from the build-hook to * the daemon's stderr, so that the SSH errors appear in the journal (which was the case before 104448e75d87d03d2fb0b4ac96d4da72e1dae50d) * the client's stderr, as a log message * NOT to the drv log (this is handled via `handleJSONLogMessage`) I tried to fix the issue for legacy-ssh as well, but failed and ultimately decided to not bother. I know that we'll sooner or later replace the entire component, however this is the part of the patch I have working for a while, so I figured I might still submit it for the time being.

I am tired of bad shell scripts, let me write bad python quickly instead. It's definitely, $100%, better. This is not planned as an immediate replacement of the old test suite, but we::jade would not oppose tests getting ported. What is here is a mere starting point and there is a lot more functionality that we need.

2024-10-08Avoid calling memcpy when len == 0 in filetransfer.ccLulu
There was a bug report about a potential call to `memcpy` with a null pointer which is not reproducible: https://git.lix.systems/lix-project/lix/issues/492 This occurred in `src/libstore/filetransfer.cc` in `InnerSource::read`. To ensure that this doesn't happen, an early return is added before calling `memcpy` if the length of the data to be copied is 0. This change also adds a test that ensures that when `InnerSource::read` is called with an empty file, it throws an `EndOfFile` exception. Change-Id: Ia18149bee9a3488576c864f28475a3a0c9eadfbb
2024-10-05fix build test error count checkseldritch horrors
with async runtime scheduling we can no longer guarantee exact error counts for builds that do not set keepGoing. the old behavior can be recovered with a number of hacks that affect scheduling, but none of those are very easy to follow now advisable. exact error counts will like not be needed for almost all uses except tests, and *those* had better check the actual messages rather than how many they got. more messages can even help to avoid unnecessary rebuilds for most users.

2024-10-01Remove static initializers for `RegisterLegacyCommand`Rebecca Turner
This moves the "legacy"/"nix2" commands under a new `src/legacy/` directory, instead of being scattered around in a bunch of different directories. A new `liblegacy` build target is defined, and the `nix` binary is linked against it. Then, `RegisterLegacyCommand` is replaced with `LegacyCommand::add` calls in functions like `registerNixCollectGarbage()`. These registration functions are called explicitly in `src/nix/main.cc`.

2024-09-29libstore: remove Goal::keyeldritch horrors
this was a debugging aid from day one that should not have any impact on build semantics, and if it *does* have an impact on build semantics then build semantics are seriously broken. keeping the order imposed by these keys will be impossible once we let a real event loop schedule our jobs.

2024-09-29libstore: fix build testseldritch horrors
the new event loop could very occasionally notice that a dependency of some goal has failed, process the failure, cause the depending goal to fail accordingly, and in the doing of the latter two steps let further dependencies that previously have not been reported as failed do their reporting anyway. in such cases a goal could fail with "1 dependencies failed", but more than one dependency failure message was shown. we'll now report the correct number of failed dependency goals in all cases.

2024-09-28libfetchers/git: restore compat with `builtins.fetchGit` from 2.3Maximilian Bosch
Since fb38459d6e58508245553380cccc03c0dbaa1542, each `ref` is appended with `refs/heads` unless it starts with `refs/` already. This regressed two use-cases that worked fine before: * Specifying a commit hash as `ref`: now, if `ref` looks like a commit hash it will be directly passed to `git fetch`. * Specifying a tag without `refs/tags` as prefix: now, the fetcher prepends `refs/*` to a ref that doesn't start with `refs/` and doesn't look like a commit hash. That way, both a branch and a tag specified in `ref` can be fetched. The order of preference in git is * file in `refs/` (e.g. `HEAD`) * file in `refs/tags/` * file in `refs/heads` (i.e. a branch) After fetching `refs/*`, ref is resolved the same way as git does.

2024-09-26fix(nix fmt): remove the default "." argumentzimbatm
When `nix fmt` is called without an argument, Nix appends the "." argument before calling the formatter. The comment in the code is: > Format the current flake out of the box This also happens when formatting sub-folders. This means that the formatter is now unable to distinguish, as an interface, whether the "." argument is coming from the flake or the user's intent to format the current folder. This decision should be up to the formatter. Treefmt, for example, will automatically look up the project's root and format all the files. This is the desired behaviour. But because the "." argument is passed, it cannot function as expected. Upstream-PR: https://github.com/nixos/nix/pull/11438 Change-Id: I60fb6b3ed4ec1b24f81b5f0d76c0be98470817ce

2024-09-25main: log stack traces for std::terminateJade Lovelace
These stack traces kind of suck for the reasons mentioned on the CppTrace page here (no symbols for inline functions is a major one): https://github.com/jeremy-rifkin/cpptrace I would consider using CppTrace if it were packaged, but to be honest, I think that the more reasonable option is actually to move entirely to out-of-process crash handling and symbolization. The reason for this is that if you want to generate anything of substance on SIGSEGV or really any deadly signal, you are stuck in async-signal-safe land, which is not a place to be trying to run a symbolizer. LLVM does it anyway, probably carefully, and chromium *can* do it on debug builds but in general uses crashpad: https://source.chromium.org/chromium/chromium/src/+/main:base/debug/stack_trace_posix.cc;l=974;drc=82dff63dbf9db05e9274e11d9128af7b9f51ceaa;bpv=1;bpt=1 However, some stack traces are better than *no* stack traces when we get mystery exceptions falling out the bottom of the program. I've also promoted the path for "mystery exceptions falling out the bottom of the program" to hard crash and generate a core dump because although there's been some months since the last one of these, these are nonetheless always *atrociously* diagnosed. We can't improve the crash handling further until either we use Crashpad (which involves more C++ deps, no thanks) or we put in the ostensibly work in progress Rust minidump infrastructure, in which case we need to finish full support for Rust in libutil first. Sample report: Lix crashed. This is a bug.

2024-09-18util: fix brotli decompression of empty inputJade Lovelace
This caused an infinite loop before since it would just keep asking the underlying source for more data. In practice this happened because an HTTP server served a response to a HEAD request (for which curl will not retrieve any body or call our write callback function) with Content-Encoding: br, leading to decompressing nothing at all and going into an infinite loop. This adds a test to make sure none of our compression methods do that again, as well as just patching the HTTP client to never feed empty data into a compression algorithm (since they absolutely have the right to throw CompressionError on unexpectedly-short streams!).

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.

2024-08-21libutil/config: unify path setting typesAlois Wohlschlager
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).

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

2024-08-10nix: remove explosions if you have a window size less than fourJade Lovelace
Turns out strings do not like being resized to -4. This was discovered while messing with the tests to remove unbuffer and trying stdbuf instead. Turns out that was not the right approach. This basically rewrites the handling of this case to be much more correct, and fixes a bug where with small window sizes where it would ALSO truncate the attr names in addition to the optional descriptions.

2024-08-10build: remove expect as a dependencyJade Lovelace
I was packaging Lix 2.91 for nixpkgs and was annoyed at the expect dependency. Turns out that you can replace unbuffer with a pretty-short Python script. It became less short after I found out that Linux was converting \n to \r\n in the terminal subsystem, which was not very funny, but is at least solved by twiddling termios bits.
