flake: fix devShell on i686-linux by disabling ClangBuildAnalyzer on it
flake: fix eval of checks & devshell on i686-linux
flake: move the pre-commit definition to its own file
ClangBuildAnalyzer doesn't build on i686-linux due to
`long long int`/`size_t` conversion errors, so let's just exclude it
from the devshell on that platform

Because of an objc quirk[1], calling curl_global_init for the first time
after fork() will always result in a crash.
Up until now the solution has been to set
OBJC_DISABLE_INITIALIZE_FORK_SAFETY for every nix process to ignore
that error.
This is less than ideal because we were setting it in package.nix,
which meant that running nix tests locally would fail because
that variable was not set.
Instead of working around that error we address it at the core -
by calling curl_global_init inside initLibStore, which should mean
curl will already have been initialized by the time we try to do so in
a forked process.

The big ones here are `trim-trailing-whitespace` and `end-of-file-fixer`
(which makes sure that every file ends with exactly one newline
character).

I didn't enable this by default for clang due to making the build time
10% worse or so. Unfortunate, but tbh devs for whom 10% of build time is
not *that* bad should probably simply enable this.

hacking changelog-d to support not just github but also forgejo and
gerrit is a lot more complicated than it's worth, even moreso since
the entire thing can just as well be done with ~60 lines of python.
this new script is also much cheaper to instantiate (being python),
so having it enabled in all shells is far less of a hassle.
we've also adjusted existing release notes that referenced a gerrit
cl to auto-link to the cl in question, making the diff a bit bigger

This provides a platform-independent way to configure the SSL
certificates file in the Nix daemon. Previously we provided
instructions for overriding the environment variable in launchd, but
that obviously doesn't work with systemd. Now we can just tell users
to add
ssl-cert-file = /etc/ssl/my-certificate-bundle.crt
to their nix.conf.
This matches the behavior of bash. We don’t want to add a space after
completion on attrs. Uses -S.
Switches to new compadd style comppletions instead of _describe.
Shouldn’t have any negative issues from what I can tell.
Users may want to mount a filesystem just for the Nix database, with
the filesystem's parameters specially tuned for sqlite. For example, on
ZFS you might set the recordsize to 64k after changing the database's
page size to 65536.
nix-daemon.socket is used to socket-activate nix-daemon.service when
/nix/var/nix/daemon-socket/socket is accessed.
In container usecases, sometimes /nix/var/nix/daemon-socket is
bind-mounted read-only into the container.
In these cases, we want to skip starting nix-daemon.socket.
However, since systemd 250, `ConditionPathIsReadWrite` is also not met
if /nix/var/nix/daemon-socket doesn't exist at all. This means, a
regular NixOS system will skip starting nix-daemon.socket:
> [ 237.187747] systemd[1]: Nix Daemon Socket was skipped because of a failed condition check (ConditionPathIsReadWrite=/nix/var/nix/daemon-socket).
To prevent this from happening, ship a tmpfiles file that'll cause the
directory to be created if it doesn't exist already.
In the case of NixOS, we can just add Nix to `systemd.tmpfiles.packages`
and have these files picked up automatically.
Allows completing `nix build ~/flake#<Tab>`.
We can implement expansion for `~user` later if needed.
Not using wordexp(3) since that expands way too much.
The default maxfiles on macOS 11 and macOS 12 is 256, which is too low
for nix to work:
```
$ launchctl limit maxfiles
maxfiles 256 unlimited
```
Set NumberOfFiles of nix-daemon to 4096 to avoid `Too many open files`
error.
This is only rudimentary support as allowed by `NIX_GET_COMPLETIONS`.
In the future, we could use complete’s `--wraps` argument to autocomplete arguments for programs after `nix shell -c`.
Previously, the build system used uname(1) output when it wanted to
check the operating system it was being built for, which meant that it
didn't take into-account cross-compilation when the build and host
operating systems were different.
To fix this, instead of consulting uname output, we consult the host
triple, specifically the third "kernel" part.
For "kernel"s with stable ABIs, like Linux or Cygwin, we can use a
simple ifeq to test whether we're compiling for that system, but for
other platforms, like Darwin, FreeBSD, or Solaris, we have to use a
more complicated check to take into account the version numbers at the
end of the "kernel"s. I couldn't find a way to just strip these
version numbers in GNU Make without shelling out, which would be even
more ugly IMO. Because these checks differ between kernels, and the
patsubst ones are quite fiddly, I've added variables for each host OS
we might want to check to make them easier to reuse.
Make nix output completions in the form `completion\tdescription`.
This can't be used by bash (afaik), but other shells like zsh or fish
can display it along the completion choices
Mac OS multi-user installations are currently broken because all requests
made by nix-daemon to the binary cache fail with:
```
unable to download ... Problem with the SSL CA cert (path? access rights?) (77).
```
This change ensures that the nix-daemon knows where to find the SSL CA cert file.
Fixes#2899 and #3261.
We're calling `wait4path` on the full, resolved `@bindir@/nix-daemon` path.
That means we're hardcoding something like:
/bin/wait4path /nix/store/zs9c5xhp3zv9p23qnjxp87nl5injsi1i-nix-2.3/bin/nix-daemon && /nix/var/nix/profiles/default/bin/nix-daemon
That seems unnecessarily fragile.
It might be better to wait4path on the path we intend to call.
On Catalina, the /nix filesystem might not be mounted at start time.
To avoid this service not starting, we need to keep the launch agent
outside of the Nix store. A wait4pid will hold for our /nix dir to be
mounted.
Fixes#3125.
