As part of the splicing the build/host/target combinations of the interpreter
need to be passed around internally. The chosen names were not very clear,
implying they were package sets whereas actually there were derivations.
This hook was added to get reproducible bytecode. Because it was causing
issues it was disabled, but still kept as a dependency. Now the main
issue with bytecode reproducibility has been resolved by updating pip to
20.2.4, we remove this hook as a dependency.
If a package with Python code is not yet reproducible, one could add
this hook to `nativeBuildInputs`.
fixes c88f3adb17, which resulted in
qt 5.15 being used in pythonPackages, despite 5.14 being
declared, and adapts qutebrowser accordingly.
'callPackage { pkgs = pkgs // { … }; }' does not work, because
it does not take into account the recursive evaluation of nixpkgs:
`pkgs/development/interpreters/python/default.nix` calls
`pkgs/top-level/python-packages.nix` with `callPackage`.
Thus, even if the former gets passed the updated `pkgs`,
the latter always gets passed `pkgs.pkgs`.
For the change in the qt5 version to apply consistently, 'pkgs.extend'
must be used.
qutebrowser only used the right qt5 version (5.15) because all
pythonPackages used it anyway.
Optional setting of format == "pyproject", "egg" had been documented
in the manual, but they weren't listed in the function header for
``mk-python-derivation.nix``.
This commit introduces two changes.
First, cpython gets optional BlueZ support, which is needed for
AF_BLUETOOTH sockets. Therefore bluezSupport was added as a parameter.
Second, the call to the pythonFull packages has been adjusted. The
Python packages have a self-reference called self. This was not adjusted
for the override. As a result, Python packages for this special version
of Python were not built with the overridden Python, but with the
original one.
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).
