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.

This uses skopeo to not think about docker daemons. I, however, noticed
that the docker image we had would have totally terrible cache hits, so
I rewrote it.

This can release x86_64-linux binaries to staging, with ephemeral keys.
I think it's good enough to review at least at this point, so we don't
keep adding more stuff to it to make it harder to review.

We realized that there's really no good place to put these dev facing
bulletins, and the user-facing release notes aren't really the worst
place to put them, I guess, and we do kind of hope that it converts
users to devs.

In most real world cases, the Link header is set on the redirect, not on
the final file. This regressed in Lix earlier and while new unit tests
were added to cover it, this integration test should probably have also
caught it.

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.).
This workaround should be removed when #359 is fixed.
Fixes #306.

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

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.

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.

without it.

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.

New state:
**** Time summary:

I wonder if the "regression" in codegen time is just doing the PCH
operation a few times, because meson does it per-target.

When we changed this in I91cb6eb6668f3a8eace36ecbdb01eb367861d77b to
not run in nested shells, we didn't predict that `nix develop` would do
something ridiculous and append -env to things silently. `nix-shell` of
course does not do this, so we need to tolerate both.

Reason for revert: https://git.lix.systems/lix-project/lix/issues/364
For some reason this broke `main` even though the change we are reverting passed CI! Mysterious, haunted, etc. Needs more debugging, let's turn it off for now.

I saw that boost/lexical_cast was costing about 100s in CPU time on our
compiles. We can fix this trivially by doing explicit template
instantiation in exactly one place and eliminating all other includes of
it, which is a code improvement anyway by hiding the boost.
