2024-10-18packaging: use in-tree capnproto derivationJade Lovelace
This is done because the one in nixpkgs has several problems and we don't want to conflict with them fixing those problems: - not building shared libs - not building debuginfo (more critical for us due to https://git.lix.systems/lix-project/lix/issues/549) - not setting the correct cmake build type - not setting the correct cxxflags to build the coroutine library - not building with clang (required for the coroutine library since gcc is known to miscompile coroutines *in kj*).

2024-09-27build: fix deprecated uses of configure_fileOlivia Crain
Using `configure_file` to copy files has been deprecated since Meson 0.64.0. The intended replacement is the `fs.copyfile` method. This removes the following deprecation warning that arises when a minimum Meson version is specified: `` Project [...] uses feature deprecated since '0.64.0': copy arg in configure_file. Use fs.copyfile instead `` Change-Id: I09ffc92e96311ef9ed594343a0a16d51e74b114a
2024-09-11fish-completion: leave the shell prompt intactAlois Wohlschlager
When generating shell completions, no logging output should be visible because it would destroy the shell prompt. Originally this was attempted to be done by simply disabling the progress bar (ca946860ce6ce5d4800b0d93d3f83c30d3c953c0), since the situation is particularly bad there (the screen clearing required for the rendering ends up erasing the shell prompt). Due to overlooking the implementation of this hack, it was accidentally undone during a later change (0dd1d8ca1cdccfc620644a7f690ed35bcd2d1e74). Since even with the hack correctly in place, it is still possible to mess up the prompt by logging output (for example warnings for disabled experimental features, or messages generated by `builtins.trace`), simply send it to the bit bucket where it belongs. This was already done for bash and zsh (9d840758a8d195e52e8b7d08cd9c15f6b8259724), and it seems that fish was simply missed at that time. The last trace of the no-longer-working and obsolete hack is deleted too. Fixes: https://git.lix.systems/lix-project/lix/issues/513 Change-Id: I59f1ebf90903034e2059298fa8d76bf970bc3315
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.

2024-06-25libexpr: rewrite the parser with pegtl instead of flex/bisoneldritch horrors
this gives about 20% performance improvements on pure parsing. obviously it will be less on full eval, but depending on how much parsing is to be done (e.g. including hackage-packages.nix or not) it's more like 4%-10%. this has been tested (with thousands of core hours of fuzzing) to ensure that the ASTs produced by the new parser are exactly the same as the old one would have produced. error messages will change (sometimes by a lot) and are not yet perfect, but we would rather leave this as is for later. test results for running only the parser (excluding the variable binding code) in a tight loop with inputs and parameters as given are promising: - 40% faster on lix's package.nix at 10000 iterations - 1.3% faster on nixpkgs all-packages.nix at 1000 iterations - equivalent on all of nixpkgs concatenated at 100 iterations (excluding invalid files, each file surrounded with parens) more realistic benchmarks are somewhere in between the extremes, parsing once again getting the largest uplift. other realistic workloads improve by a few percentage points as well, notably system builds are 4% faster.

2024-05-30build-time: remove 20% more by PCH'ing C++ stdlibJade Lovelace
It seems like someone implemented precompiled headers a long time ago and then it never got ported to meson or maybe didn't work at all. This is, however, blessedly easy to simply implement. I went looking for `#define` that could affect the result of precompiling the headers, and as far as I can tell we aren't doing any of that, so this should truly just be free build time savings. Previous state: Compilation (551 times): Parsing (frontend): 1302.1 s Codegen & opts (backend): 956.3 s New state: **** Time summary: Compilation (567 times): Parsing (frontend): 1123.0 s Codegen & opts (backend): 1078.1 s I wonder if the "regression" in codegen time is just doing the PCH operation a few times, because meson does it per-target.

2024-05-07Always initialize curl in parent process on darwinNikodem Rabuliński
Because of an objc quirk[1], calling curl_global_init for the first time after fork() will always result in a crash. Up until now the solution has been to set OBJC_DISABLE_INITIALIZE_FORK_SAFETY for every nix process to ignore that error. This is less than ideal because we were setting it in package.nix, which meant that running nix tests locally would fail because that variable was not set. Instead of working around that error we address it at the core - by calling curl_global_init inside initLibStore, which should mean curl will already have been initialized by the time we try to do so in a forked process.

2024-03-27build: replace changelog-d with local scripteldritch horrors
hacking changelog-d to support not just github but also forgejo and gerrit is a lot more complicated than it's worth, even moreso since the entire thing can just as well be done with ~60 lines of python. this new script is also much cheaper to instantiate (being python), so having it enabled in all shells is far less of a hassle. we've also adjusted existing release notes that referenced a gerrit cl to auto-link to the cl in question, making the diff a bit bigger closes https://git.lix.systems/lix-project/lix/issues/176 Change-Id: I8ba7dd0070aad9ba4474401731215fcf5d9d2130

This provides a platform-independent way to configure the SSL certificates file in the Nix daemon.

2022-03-18nix-daemon.conf.in: add tmpfiles file to create nix/daemon-socket directoryFlorian Klink
nix-daemon.socket is used to socket-activate nix-daemon.service when /nix/var/nix/daemon-socket/socket is accessed. In container usecases, sometimes /nix/var/nix/daemon-socket is bind-mounted read-only into the container. In these cases, we want to skip starting nix-daemon.socket. However, since systemd 250, `ConditionPathIsReadWrite` is also not met if /nix/var/nix/daemon-socket doesn't exist at all. This means, a regular NixOS system will skip starting nix-daemon.socket: > [ 237.187747] systemd[1]: Nix Daemon Socket was skipped because of a failed condition check (ConditionPathIsReadWrite=/nix/var/nix/daemon-socket). To prevent this from happening, ship a tmpfiles file that'll cause the directory to be created if it doesn't exist already. In the case of NixOS, we can just add Nix to `systemd.tmpfiles.packages` and have these files picked up automatically.
