Compilers in nixpkgs have caught up and major distros
should also have recent enough compilers. It would be
nice to have newer features like more full featured
ranges and deducing this.
Fix description of `NIX_CONF_DIR`. It currently say that it defaults to `prefix/etc/nix`, which would mean `/nix/etc/nix` on default installations, and contradicts the description in `conf-file-prefix.md`.
This fix makes the description of `NIX_CONF_DIR` consistent with `conf-file-prefix.md`, assuming that the latter is correct.
* Adds support for NIX_SSHOPTS
* Properly uses the parsed port from URL (fixes#13337)
* Don't guess the HTTP endpoint, use the response of git-lfs-authenticate
* Add an SSH Git LFS test
* Removed some unused test code
This patch allows users to specify the connection port
in the store URLS like so:
```
nix store info --store "ssh-ng://localhost:22" --json
```
Previously this failed with: `error: failed to start SSH connection to 'localhost:22'`,
because the code did not distinguish the port from the hostname. This
patch remedies that problem by introducing a ParsedURL::Authority type
for working with parsed authority components of URIs.
Now that the URL parsing code is less ad-hoc we can
add more long-awaited fixes for specifying SSH connection
ports in store URIs.

Prior patches in 54dc5314e8
and 6db6190002 fixed the default
system double for i686 and ppc/ppc64. This also patch also covers
32 bit arm and mips. ARM cpu names are taken from host_machine.cpu()
for a lack of a better option, but host_machine.cpu_family() is
preferred, since that is supposed to be somewhat standard for cross
files. Endianness is handled correctly by looking at host_machine.endian().
This also updates the documentation to be up to date to how system cpu
is translated from the host_machine specification.
For regular, non-executable files, there is no str("") between str("regular")
and str("contents"). Note that str("") is exactly 8 zero bytes, while just ""
is actual empty string (0 bytes).
This changes makes nix detect a machines available cores automatically whenever build-cores is set to 0.
So far, nix simply passed NIX_BUILD_CORES=0 whenever build-cores is set to 0. (only when build-cores is unset it was detecting cores automatically)
The behavior of passing NIX_BUILD_CORES=0 leads to a performance penalty when sourcing nixpkgs' generic builder's `setup.sh`, as setup.sh has to execute `nproc`. This significantly slows down sourcing of setup.sh
If a build directory is accessible to other users it is possible to
smuggle data in and out of build directories. Usually this is only
a build purity problem, but in combination with other issues it can
be used to break out of a build sandbox. to prevent this we default
to using a subdirectory of nixStateDir (which is more restrictive).

Makes the behavoral change of #13263 without the underlying refactor.
Hopefully this clearly safe from a perf and GC perspective, and will
make it easier to benchmark #13263.
