Ada depencencies musst be build with the same gnat version as the
project. Use a namespace as preperation to build with different gnat
versions.
gprbuild and gnatprove are still globaly visable.
this equates to -ftrivial-auto-var-init=pattern
clang has removed support for -ftrivial-auto-var-init=zero and
are unlikely to re-add it, so use -ftrivial-auto-var-init=pattern
on both compilers if only to make behaviour more consistent
between the two.
add to pkgsExtraHardening's defaultHardeningFlags.
This commit adds support for swapping out the compression algorithm
used in all major docker-tools commands that generate images. The
default algorithm remains unchanged (gzip).
This fetcher is to be used with PyPi mirrors exposing the "legacy" API, such as devpi.
A variant of this fetcher has been used in poetry2nix for years and
has served us well there to support private PyPi mirrors and Devpi.
Example usage:
``` nix
fetchPypiLegacy {
file = "urllib3-1.26.2.tar.gz";
hash = "sha256:19188f96923873c92ccb987120ec4acaa12f0461fa9ce5d3d0772bc965a39e08";
pname = "urllib3";
url = "https://pypi.org/simple";
}
```

Let's always produce empty output for zero-modules tests.
The previous version didn't work in the case of relative symlinks in
subdirectories. If "foo/bar" was a link to "baz", it would check for
a link to "baz" in the root, rather than under "foo".
We don't need to dereference the symlink ourselves for [ anyway, as it
dereferences its arguments itself, so all we need to do to fix this is
to pass it the link.
