feat(libstore/s3): add toHttpsUrl

libexpr: Fix weird formatting after treewide reformat

I didn't want to block that PR on further code review while I figured
out these new (to us) C++23 goodies.

This is a workaround for NixOS#13515
(opening the SQLite DB randomly taking a couple of seconds on ZFS).

(cherry picked from commit a7fceb5)

…3ToHttpsURL

`ParsedS3URL::toHttpsUrl` Slight optimize

SQLite: fsync db.sqlite-shm before opening the database

It is suppposed to be "post build" not "during the build" after all. Its
location now matches that for the hook case (see elsewhere in
`DerivationdBuildingGoal`).

It was in a try-catch before, and now it isn't, but I believe that it is
impossible for it to throw `BuildError`, which is sufficient for this
code motion to be correct.

Update work meeting time in README

Handle empty ports with new URL parsing

I need this for some `ParseURL` improvements, but I figure this is
better to send as its own PR.

I changed the tests willy-nilly to sometimes use
`std::list<std::string_view>` instead of `Strings` (which is
`std::list<std::string>`).

This update contains d1266642a8722f2a05e311fa151c1413d2b9653c, which
is necessary for the TOML timestamps to get tested via nixpkgsLibTests job.

This allows us to replace some very hacky and not correct string
concatentation in `HttpBinaryCacheStore`. It will especially be useful
with NixOS#13752, when today's hacks started to cause problems in practice,
not just theory.

Also make `fixGitURL` returned a `ParsedURL`.

Implement `parseURLRelative`, use in `HttpBinaryCacheStore`

flake: Update nixpkgs

With the migration to /nix/var/nix/builds we now have failing builds
when the derivation name is too long.
This change removes the derivation name from the temporary build to have
a predictable prefix length:

Also see: NixOS/infra#764
for context.

I am not sure how/why this started working. C++23?

…r-params-aggregate-initialize

No more `DerivationBuilderParams:` constructor!

A follow-up optimization will make it impossible to make a find function
that returns an iterator in an efficient manner. All consumer code can
easily use the `get` variant.

- Use `const K`, not `K`, otherwise we don't get auto referencing of

meson: add soversion with nix version to give SONAME to libs

Since `nix flake check` doesn't produce a `result` symlink, it doesn't
actually need to build/substitute derivations that are already known
to have succeeded, i.e. that are substitutable.

This can speed up CI jobs in cases where the derivations have already
been built by other jobs. For instance, a command like

  nix flake check github:NixOS/hydra/aa62c7f7db31753f0cde690f8654dd1907fc0ce2

should no longer build anything because the outputs are already in
cache.nixos.org.

Use `MemorySourceAccessor` in `DummyStore` so writes work

This changes the implementation of Bindings to allow
for a more space-efficient implementation of attribute
set merges. This is accomplished by "layering" over the "base" Bindings.
The top "layer" is naturally the right-hand-side of the update operator //.

Such an implementation leads to significantly better memory usage on
something like nixpkgs:

nix-env --query --available --out-path --file ../nixpkgs --eval-system x86_64-linux > /dev/null

Overall this does slow down the evaluator slightly (no more than ~10% in most cases),
but this seems like a very decent tradeoff for shaving off 33% of memory usage.
