we don't even need this outside of tests. maybe we should not do
automatic retries at this level at all and use retrying wrappers
instead? at some point we may have to do this, but not just yet.

it's only used by HttpBinaryCacheStore, and even there used in only on

it only sets the one field anyway (and the parent activity as a side
effect that does not depend on the exact location of the constructor
call). when FileTransferRequest goes away we would need this anyway.

this is fragile, slow as fuck, breaks constantly under high concurrency,
and completely unnecessary since ssh bypasses the stdio file descriptors
*anyway*. we do still check that we see ssh messages to ensure that none
of our subprocess handling messes with ssh's /dev/tty, but that's it now

* changes:
treewide: make more settings conditionally available
libstore/build: only send overridden settings to the build hook
treewide: consistently mark overridden settings as such
a first little step into pushing the event loops up, up and away.
eventually we will want them to be instantiated only at the roots
of every thread (since kj binds loops to threads), but not today.

goals should be considered internal to the worker architecture due to
the tight coupling of the two, and we can finally do that. doing this
is also a prerequisite for turning Worker::run() into a real promise.

previously it was possible to fetchurl a dict server, or an ldap server,
or an imap server. this is a bit of a problem, both because rare schemes
may not be available on all systems, and because some schemes (e.g. scp)
are inherently insecure in potentially surprising ways we needn't allow.
Change-Id: I18fc567c6f58c3221b5ea8ce927f4da780057828
we already have a results type for the entire worker call, we may as
well put this bit of info in there. we do keep the assumption of the
old code that the field will only be read if some goals have failed;
fixing that is a very different mess, and not immediately necessary.

without this derivations do not show as completely processed in the
internal-json logs (or the newer multiline output). the former also
breaks external tools like nix-output-monitor which, like multiline
output, grow vertically until at least some goals are finally freed

optimise-store.cc used std::regex on darwin, but forgot to include the
header. This probably compiled due to the precompiled headers file, but
it caused errors in the editor.

It's not clear to me if `proc_pidinfo()` or `proc_pidfdinfo()` can
actually return negative values, the syscall wrappers convert `-1` into
zero and the semantics suggest that negative values don't make sense,
but just to be safe we'll preserve the int type until we've checked that
it's a positive value.

some promises capture `this`. we could also allocate a shared state,
but this thing doesn't really need to ever be moved anyway. so there.

not doing this can freeze slots until the goal that occupied them is
freed (rather than simply complete), and then can freeze the system.

Daemon client handler processes are forked off of the main nix process
and thus will not have a signal handler thread anymore. This leads to a
high likelihood of bustage, since the Worker infrastructure expects the
interrupt infrastructure to actually, you know, work, to be able to get
interrupted.
The expected behaviour after fork is either:
- Start a signal handler thread if you expect to do complicated things
that need ReceiveInterrupts.
- Call restoreProcessContext and don't handle signals specially
otherwise.

This is done because the one in nixpkgs has several problems and we
don't want to conflict with them fixing those problems:
- not building shared libs
- not building debuginfo (more critical for us due to
lix-project/lix#549)
- not setting the correct cmake build type
- not setting the correct cxxflags to build the coroutine library
- not building with clang (required for the coroutine library since gcc
is known to miscompile coroutines *in kj*).

The old behavior results in lots of concatenations happening for no good
reason and is an artifact of the technical limitations of the old parser
(combined with some lack of care for such details).
Change-Id: I0d78d6220ca6aeaa10bc437e48e08bf7922e0bb3
This is only a minor semantical distinction, but we should be able to
properly test it, and the parser tests rely on show for that.

This commit should faithfully reproduce the old behavior down to the
bugs. The new code is a lot more readable, all quirks are well
documented, and it is overall much more maintainable.

Some settings only make sense on particular platforms, or only when a certain
experimental feature is enabled. Several of those were already conditionally
available. Do the same for a bunch more instead of silently ignoring them.
Exceptionally, the use-case-hack setting is not made conditional because it is
included in the test suite.
Change-Id: I29e66ad8ee6178a7c0eff9efb55c3410fae32514
The build hook is still running locally, so it will run with the same default
settings. Hence, just as with the daemon, it is enough to send it only the
overridden settings. This will prevent warnings like
warning: Ignoring setting 'auto-allocate-uids' because experimental feature 'auto-allocate-uids' is not enabled
when the user didn't actually set those settings.
This is inspired by and an alternative to [0].

Only overridden settings are sent to the daemon, and we're going to do the same
for the build hook to. It needs to be ensured that overridden settings are in
fact consistently marked as such, so that they actually get sent.

This failed due to https://github.com/NixOS/nixpkgs/pull/346945, which
makes a second lowdown-unsandboxed that works in nix builds, and the
regular lowdown has executables that fail closed when the sandbox setup
fails.
The actual failure here is only visible on nixos-unstable at the moment,
not 24.05, but this commit should fix it up for all versions.
