2024-05-27shell.nix: conform to documentationstuebinm
According to doc/manual/src/contributing/hacking.md, all development shells should also be available in classic nix using the -A argument to nix-shell, e.g. nix-shell -A native-clangStdenvPackages This was not actually the case; flake-compat generates attrsets like nix-shell -A devShells.x86_64-linux.native-clangStdenvPackages instead. These are unwieldy to use, so rather than changing the docs, this changes the shell.nix file to result in the documented behavior. Change-Id: I0920ccbdfddacf371f0aeaae7e290db65cf76ee7

2024-05-26worker: process timeouts first, and exclusivelyeldritch horrors
check goals for timeouts first, and their activity fds only if no timeout has occurred. checking for timeouts *after* activity sets us up for assertion failures by running multiple build completion notifiers, the first of which will kill/reap the the goal process and consuming the Pid instance. when the second notifier attempts to do the same it will core dump with an assertion failure in Pid and take down not only the single goal, but the entire daemon and all goals it was building. luckily this is rare in practice since it requires a build to both finish and time out at the same time. writing a test for this is not feasible due to how much it relies on scheduling to actually trigger the underlying bug, but on idle machines it can usually be triggered by running multiple sleeping builds with timeout set to the sleep duration and `--keep-going`: nix-build --timeout 10 --builders '' --keep-going -E ' with import <nixpkgs> {}; builtins.genList (i: runCommand "foo-${toString i}" {} "sleep 10") 100 ' Change-Id: I394d36b2e5ffb909cf8a19977d569bbdb71cb67b

2024-05-25libfetchers: fix URL loggingQyriad
8c06b7b43¹ made libfetchers log the URL being fetched just before the actual fetch, particularly in case something freezes. This used the base URL, to not include query parameters, as the Nixpkgs lib tests assume that stderr logs will be equal across shallow and non-shallow git fetches (and shallow fetches have the ?shallow=1 query parameter). 8c06b7b43 assumed that the `base` field of ParsedURL would be populated, as the comment simply says "URL without query/fragment"... but apparently it is not populated when the URL being fetched is *already* fetched, which caused libfetchers to log things like fetching gitlab input '' which is. silly. but you know, busted lix be busted. Anyway, with this commit we just remove the query params before printing instead, which seems to do the right thing [1]: 8c06b7b431d73431d8872c28d1ec5009cecd5d03 Change-Id: I9b9988992029aa6abef786f20b66e68c2ebb97d4
2024-05-25libstore: remove duplicate builder variableArtemis Tosini
The `builder` local variable and duplicate `args.push_back` are no longer required since the Darwin sandbox stopped using `sandbox-exec`. The `drv->isBuiltin` check is not required either, as args are not accessed when the builder is builtin. Change-Id: I80b939bbd6f727b01793809921810ff09b579d54

2024-05-24libstore/build: always enable seccomp filtering and no-new-privilegesAlois Wohlschlager
Seccomp filtering and the no-new-privileges functionality improve the security of the sandbox, and have been enabled by default for a long time. In https://git.lix.systems/lix-project/lix/issues/265 it was decided that they should be enabled unconditionally. Accordingly, remove the allow-new-privileges (which had weird behavior anyway) and filter-syscall settings, and force the security features on. Syscall filtering can still be enabled at build time to support building on architectures libseccomp doesn't support. Change-Id: Iedbfa18d720ae557dee07a24f69b2520f30119cb

2024-05-24[emergency revert]: make pname nix once moreJade Lovelace
Embarrassingly, I submitted a CL overriding submit requirements since I thought it was spurious failures. However, the CI failure was in fact real, and I have hopefully learned my lesson. The CI failure is that: ``` vm-test-run-nix-upgrade-nix> machine # installing 'nix-2.18.1' vm-test-run-nix-upgrade-nix> machine # building '/nix/store/2b6fdf7wvahd00bg2ff0393bhd597a0h-user-environment.drv'... vm-test-run-nix-upgrade-nix> machine # error: Unable to build profile.

2024-05-23packaging: rename nixexpr -> lixexpr and so onJade Lovelace
This breaks downstreams linking to us on purpose to make sure that if someone is linking to Lix they're doing it on purpose and crucially not mixing up Nix and Lix versions in compatibility code. We still need to fix the internal includes to follow the same schema so we can drop the single-level include system entirely. However, this requires a little more effort. This adds pkg-config for libfetchers and config.h. Migration path: expr.hh -> lix/libexpr/expr.hh nix/config.h -> lix/config.h To apply this migration automatically, remove all `<nix/>` from includes, so: `#include <nix/expr.hh>` -> `#include <expr.hh>`. Then, the correct paths will be resolved from the tangled mess, and the clang-tidy automated fix will work. Then run the following for out of tree projects: ``` lix_root=$HOME/lix (cd $lix_root/clang-tidy && nix develop -c 'meson setup build && ninja -C build') run-clang-tidy -checks='-*,lix-fixincludes' -load=$lix_root/clang-tidy/build/liblix-clang-tidy.so -p build/ -fix src ``` Related: https://git.lix.systems/lix-project/nix-eval-jobs/pulls/5 Fixes: https://git.lix.systems/lix-project/lix/issues/279 Change-Id: I7498e903afa6850a731ef8ce77a70da6b2b46966

2024-05-23repl: do not crash when tab-completing import errorsPierre Bourdon
File not found while importing causes a SysError, not an EvalError, which is not currently caught by the tab-completion handler. Ignoring all SysErrors might seem "dangerous" but this is the tab-completion handler, any exception being bubbled up from there causes unexpected behavior (causes the whole repl to exit). Fixes #340.
