2024-06-12tests/libcmd: set HOME to a temporary directoryAlois Wohlschlager
The libcmd unit test creates files (more specifically, the fetcher cache) in its home directory. In the single-user sandbox, this leads to the creation of /homeless-shelter, since this is the default HOME and the root is writable. Unfortunately, this conflicts with the assumption of the functional tests that this directory does not exist. Use a different home directory to prevent these test failures, and thus restore the ability to build inside the single-user sandbox.

2024-06-10Revert "flake: update nixpkgs pin 23.11->24.05 (+ boehmgc compat changes)"jade
This reverts commit 28a079f841834ac11105ce5762115904d1e40ce1. Reason for revert: This caused a pile of regressions in CI, and does not pass nix flake check. Some number of them are fixed in CL: https://gerrit.lix.systems/c/lix/+/1429 but there's more to be fixed. We should defer this after 2.90. Change-Id: Ib839d0fcb08eb52094af2b521145e3c1b4e0556f
2024-06-09releng: add prod environment, ready for releaseJade Lovelace
I am *reasonably* confident that this releng infrastructure can actually build a Lix 2.90 and release it successfully. Let's make it possible to do, and add some cute colours to the confirmation message. Change-Id: I85e498b6fb49ffc5e75c0a72c5e45fb1f69030d3
2024-06-09releng: automatically figure out if we should tag latest for dockerJade Lovelace
For example, when releasing from release-2.90, if `main` has a 2.91 tag ancestor, we know that 2.91 was released, so we should *not* tag latest. Change-Id: Ia56b17a2ee03bbec74b7c271c742858c690d450d
2024-06-09releng: support multiarch docker imagesJade Lovelace
If we don't want to have separate registry tags by architecture (EWWWW), we need to be able to build multiarch docker images. This is pretty simple, and just requires making a manifest pointing to each of the component images. I was *going* to just do this API prodding with manifest-tool, but it doesn't support putting metadata on the outer manifest, which is actually kind of a problem because it then doesn't render the metadata on github. So I guess we get a simple little containers API implementation that is 90% auth code. Change-Id: I8bdd118d4cbc13b23224f2fb174b232432686bea

2024-06-09Rewrite docker to be sensible and smallerJade Lovelace
I have checked the image can build things and inspected `diff -ru` compared to the old image. As far as I can tell it is more or less the same besides the later git change. Layers are now 65MB or less, and we aren't against the maxLayers limit for the broken automatic layering to do anything but shove one store path in a layer (which is good behaviour, actually). This uses nix2container which streams images, so the build time is much shorter. I have also taken the opportunity to, in addition to fixing the 400MB single layer (terrible, and what motivated this in the first place), delete about 200MB of closure size inflicted by git vs gitMinimal causing both perl and python to get into closure. People mostly use this thing for CI, so I don't really think you need advanced git operations, and large git can be added at the user side if really motivated. With love for whichever container developer somewhat ironically assumed that one would not run skopeo in a minimal container that doesn't have a /var/tmp.

2024-06-09flake: update nixpkgs pin 23.11->24.05 (+ boehmgc compat changes)Pierre Bourdon
The boehmgc changes are bundled into this commit because doing otherwise would require an annoying dance of "adding compatibility for < 8.2.6 and >= 8.2.6" then updating the pin then removing the (now unneeded) compatibility. It doesn't seem worth the trouble to me given the low complexity of said changes.

2024-06-08tests: fix daemon version in isDaemonNewer functionMario Rodas
Since ad8a4b380e, the version printer returns "nix (Lix, like Nix) 2.x", hence the `daemonVersion` was being set to the string "like". Using `compareVersions` with a letter compares them lexicographically: builtins.compareVersions "like" "2.12pre20230103" // => -1 builtins.compareVersions "like" "2.16.0" // => -1 This caused that `isDaemonNewer` always returned 1, falsy in Bash terms. Therefore, the test suite skipped those tests where they use it. Fixes https://git.lix.systems/lix-project/lix/issues/324 Change-Id: If6682515bf0bf8b8add641af9a4e98b50a9acb51

2024-05-31build: fix static linking with a hackQyriad
This causes libstore, libexpr, libfetchers, and libutil to be linked with -Wl,--whole-archive to executables, when building statically. libstore for the store backends, libexpr for the primops, libfetchers for the fetcher backends I assume(?), and libutil for the nix::logger initializer (which notably shows in pre-main constructors when HOME is not owned by the user. cursed.).

Fix for https://github.com/NixOS/nix/issues/10300 https://github.com/lix-project/lix/commit/18a26202737a74f216d285d92bd4a84761788026 enabled persistent WAL files that will never get truncated. to fix this, journal_size_limit is set to 2^40, which results in the WAL files being truncated to 0 on exit, as well as limiting the WAL files to 2^40 bytes following a checkpoint. this aligns lix with the nix change: https://github.com/NixOS/nix/pull/10301 https://www.sqlite.org/c3ref/c_fcntl_begin_atomic_write.html#sqlitefcntlpersistwal https://www.sqlite.org/pragma.html#pragma_journal_size_limit https://github.com/sqlite/sqlite/blob/ed517a708284b6e00b6ae5f1e3f702bbfcbd32ed/src/wal.c#L2518 PR-Link: https://github.com/lix-project/lix/pull/9 Co-Authored-By: paparodeo <170618376+paparodeo@users.noreply.github.com> Change-Id: I90ec1a467c92c582ff8c07dd363a4cf789782214

Fixes: https://git.lix.systems/lix-project/lix/issues/157 Fixes: https://git.lix.systems/lix-project/lix/issues/221 Previously the entire escaped store URI was included. This would cause build failures if a very long or deeply nested path was being used in the store. Now, we use the first 48 characters of the URL (escaped), then 16 bytes of hash of the entire URL. This should never collide and limits the length of the file name to a bit over 64, which is fine. Change-Id: Ic1ba690a94e83749567c2c29460b8d1bcf2ac413
2024-05-31libutil: fix args assert being thrown on Darwin in nix-eval-jobsJade Lovelace
This is because a dynamic_cast<nix::RootArgs *> of a (n-e-j) MyArgs returns nullptr even though MyArgs has virtual nix::RootArgs as a parent. class MyArgs : virtual public nix::MixEvalArgs, virtual public nix::MixCommonArgs, virtual nix::RootArgs { ... }; So this should work right?? But it does not. We found out that it's caused by -fvisibility=hidden in n-e-j, but honestly this code was bad anyway. The trivial solution is to simply stop relying on RTTI working properly here, which is probably better OO architecture anyway. However, I am not 100% confident *this* is sound, since we have this horrible hierarchy: Args (defines getRoot) / | \ RootArgs MixCommonArgs MixEvalArgs (overrides) I am not confident that this is guaranteed to resolve from Args always in the case of this override. Assertion failed: (res), function getRoot, file src/libutil/args.cc, line 67. 6MyArgsProcess 60503 stopped * thread #1, queue = 'com.apple.main-thread', stop reason = hit program assert frame #4: 0x0000000100b1a41c liblixutil.dylib`nix::Args::processArgs(std::__1::list<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>, std::__1::allocator<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>>> const&, bool) [inlined] nix::Args::getRoot(this=0x00000001000d0688) at args.cc:67:5 [opt] 64 std::cout << typeid(*p).name(); 65 66 auto * res = dynamic_cast<RootArgs *>(p); -> 67 assert(res); 68 return *res; 69 } 70 Target 0: (nix-eval-jobs) stopped.
