766e718f67 devshells: only enable pch for clang
clangd seems to break if GCC is using precompiled headers for C++'s
standard library, so this sets -Denable-pch-std=${stdenv.cc.isClang}

Fixes #374.

06e65e537b build: expose option to enable or disable precompiled std headers
They are enabled by default, and Meson will also prints whether or not
they're enabled at the bottom at the end of configuration.

tests/nixos: make the tarball-flakes test better reflect real use cases
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.

-g '!doc/' --pcre2

All items from this query have been tackled. For the documentation side:

e54d4c9381 build: fix static linking with a hack
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.

713cd7e9e7 truncate WAL files on exit
Fix for https://github.com/NixOS/nix/issues/10300

18a2620273  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

d4b7e6baca build-remote: truncate+hash store URI used in lockfile paths
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.

ac78c1dcd5 libutil: fix args assert being thrown on Darwin in nix-eval-jobs
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.

We also found that if we did this:
class [[gnu::visibility("default")]] RootArgs : virtual public Args

it would work properly (???!). This is of course, very strange, because
objdump -Ct output on liblixexpr.dylib is identical both with and
without it.

0f99ed43f1 build-time: remove 20% more by PCH'ing C++ stdlib
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.

e6e5cacabe shellHook: make it actually run
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.

7575db522e Remove 100s of CPU time (10%) from build times (1465s -> 1302s)
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.

eac3546d50 package: return from shellHook correctly
If our shellHook is being run from a nested nix-shell (see 7a12bc200¹),
then (I think) it is run from a bash function due to the nesting, then
`return` is correct. If its `eval`'d though, then there isn't really a
correct way to early exit. So we can just unconditionally be executed in
a function.

Basically, we have IIFE at home.

285bc67318 tests/filetransfer: reënable on Darwin
Since we put __darwinAllowLocalNetworking in our derivation in
I752b81c85ebeaab4e582ac01c239d69d65580f37, this stuff will just work
fine. I checked our derivation works on the darwin community builder.

26b3a1b9ce unix-domain-socket.cc: add comment explaining why bindConnectProcHelper
We reviewed this code a while ago, and we neglected to get a comment in
saying why it's Like This at the time. Let's fix that, since it is code
that looks very absurd at first glance.

afeaa2371c docs: enable non-default TOC folding
Folding by default would prevent things like "Ctrl+F for nix-env" from
working trivially, but the user should be able to fold if they want to.
