This appears to be needed in some Python distutils for the library to
get on RPATH correctly. I’m not sure why this worked before, but I
needed this value set for Python 3.8 numpy to work correctly.
This is needed to build the CUDNN samples, so we should make sure it
winds up in $out/lib. The library is too big to support patchelf, so
we need to skip it. Most programs will still get the opengl path
because it also links to other libraries.
This adds an option to skip adding --copt and --linkopt to Bazel
flags. In some cases, Bazel doesn’t like these flags, like when a
custom toolchain is being used (as opposed to the builtin one. The
compiler can still get the dependencies since it is invoked through
gcc wrapper and picks up the NIX_CFLAGS_COMPILE / NIX_LDFLAGS.
This appears to avoid requiring KVM when it’s not available. This is
what I originally though -cpu host did. Unfortunately not much
documentation available from the QEMU side on this, but this appears
to square with help:
$ qemu-system-x86 -cpu help
...
x86 host KVM processor with all supported host features
x86 max Enables all features supported by the accelerator in the current host
...
Whether we actually want to support this not clear, since this only
happens when your CPU doesn’t have full KVM support. Some Nix builders
are lying about kvm support though. Things aren’t too slow without it
though.

In some contexts, we don’t want to have to build the whole i686 stdenv
just to use the x86_64 nvidia driver. It’s hard to know ahead of time
what we want, so it’s best to leave this as an overridable option.
This adds a warning to the top of each “boot” package that reads:
Note: this package is used for bootstrapping fetchurl, and thus cannot
use fetchpatch! All mutable patches (generated by GitHub or cgit) that
are needed here should be included directly in Nixpkgs as files.
This makes it clear to maintainer that they may need to treat this
package a little differently than others. Importantly, we can’t use
fetchpatch here due to using <nix/fetchurl.nix>. To avoid having stale
hashes, we need to include patches that are subject to changing
overtime (for instance, gitweb’s patches contain a version number at
the bottom).
Unfortunately the output of git.savannah.nongnu.org changes with each
gitweb update. This means that the current has
“0gja54fz79a9ma6b4mprnjxq77l5yg2z9xknlwhmkcrfnam02qxp” is no longer
correct:
$ nix-prefetch-url
https://git.savannah.nongnu.org/cgit/attr.git/patch/\?id=14adc898a36948267bfe5c63b399996879e94c98

Normally, we use fetchpatch to strip this out, but unfortunately attr
cannot use fetchpatch due to being used in bootstrapping fetchurl.
That is, it can’t use a custom postFetch since <nix/fetchurl.nix>
doesn’t support that.
To solve this problem, just inline the patch for now.
This is needed for cross-compiling for LLVM.
After https://github.com/NixOS/nixpkgs/pull/94088, we still need some
of these, so I’ve whitelisted those that are in binutils.

We need to set FC so that CMake and other tools can find the fortran
compiler. Also we need to limit the hardening flags since fortify and
format don’t work with fortran.

This makes it possible to only start IPFS when needed. So a user’s
IPFS daemon only starts when they actually use it.
A few important warnings though:
- This probably shouldn’t be mixed with services.ipfs.autoMount
since you want /ipfs and /ipns aren’t activated like this
- ipfs.socket assumes that you are using ports 5001 and 8080 for the
API and gateway respectively. We could do some parsing to figure
out what is in apiAddress and gatewayAddress, but that’s kind of
difficult given the nonstandard address format.
- Apparently? this doesn’t work with the --api commands used in the tests.
Of course you can always start automatically with startWhenNeeded =
false, or just running ‘systemctl start ipfs.service’.
Tested with the following test (modified from tests/ipfs.nix):
import ./make-test-python.nix ({ pkgs, ...} : {
name = "ipfs";
nodes.machine = { ... }: {
services.ipfs = {
enable = true;
startWhenNeeded = true;
};
};
testScript = ''
start_all()
machine.wait_until_succeeds("ipfs id")
ipfs_hash = machine.succeed("echo fnord | ipfs add | awk '{ print $2 }'")
machine.succeed(f"ipfs cat /ipfs/{ipfs_hash.strip()} | grep fnord")
'';
})

Previously we had three services for different config flavors. This is
confusing because only one instance of IPFS can run on a host / port
combination at once. So move all into ipfs.service, which contains the
configuration specified in services.ipfs.
Also remove the env wrapper and just use systemd env configuration.
