makes the pythonsrc reproducible by making the file date and
ordering static.
A more general solution to this problem has been proposed in
https://github.com/NixOS/nixpkgs/issues/106643
As requested in #99553. Closes#99553.
Libraries that install python modules as part of the build are
problematic, because they either
- only support a single python version, because the input for
pythonPackages gets fixed in all-packages.nix, or
- need to be rebuild the underlying C code for *every* python version
resulting in libfoo-python37, libfoo-python38, and so on
We would prefer to use the second approach because it works correctly
for all versions of python. However, it creates duplicate copies of
libseccomp.so and that can be expensive. Instead we 'deduplicate' the
copies of libseccomp.so by
- attaching a new $pythonsrc output to the libseccomp deriv, and
- exposing a new 'seccomp' package in python-packages.nix using
libseccomp as input, and
- having a custom python.nix derivation that builds the cython
extension using libseccomp to get the python source and the
package version
This means we build 1 copy of the seccomp python package, one for each
version of python, but all of those packages refer to a single instance
of the libseccomp C library, giving us the best of both worlds.
NOTE: because this requires changing the postInstall of libseccomp, it
requires a mass rebuild.

He prefers to contribute to his own nixpkgs fork triton.
Since he is still marked as maintainer in many packages
this leaves the wrong impression he still maintains those.
The isSeccomputable flag treated Linux without seccomp as just a
normal variant, when it really should be treated as a special case
incurring complexity debt to support.
Ensure that bin/scmp_sys_resolver doesn't have $TMPDIR in its RPATH.
I can't reproduce the issue reported in
98edb24368 that required the addition of
a wrapper script. It seems to work fine without.
In line with the Nixpkgs manual.
A mechanical change, done with this command:
find pkgs -name "*.nix" | \
while read f; do \
sed -e 's/description\s*=\s*"\([a-z]\)/description = "\u\1/' -i "$f"; \
done
I manually skipped some:
* Descriptions starting with an abbreviation, a user name or package name
* Frequently generated expressions (haskell-packages.nix)
