PHP 7.3 won't be supported by upstream for the entire life cycle of
the 21.11 release.
Also drop the pcre' alias since it isn't needed anymore since we don't
need different pcre versions anymore.
continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
This will make it easier to make overridable.
Had to rename `packages` attribute to `tools` in `php-packages.nix` because `packages` is shadowed by `makeScope`.
* Backported patches from `php-7.4` which fixes the env for all
`gettext` and `zlib` tests.
* Setting `--with-libxml-dir` is still needed for versions 7.2 and 7.3.
Some PECLs depend on other PECLs and, like internal PHP extension
dependencies, need to be loaded in the correct order. This makes this
possible by adding the argument "peclDeps" to buildPecl, which adds
the extension to buildInputs and is treated the same way as
internalDeps when the extension config is generated.
At the moment, using .withExtensions on a PHP derivation will
produce something which can't be used inside an
environment.systemPackages array, because outputsToInstall refers
to an output which doesn't exist on the final derivation.
Instead, override it back to just containing the single output
"out".
Also passthrough the meta of the package to have description,
homepage, license, maintainers and other metadata passed through to
the commonly used attribute.
Instead of using two different php packages in php-packages.nix, one
wrapper and one unwrapped, simply use the wrapper and use its
"unwrapped" attribute when necessary. Also, get rid of the packages
and extensions attributes from the base package, since they're no
longer needed.
Since the introduction of php.unwrapped there's no real need for the
phpXXbase attributes, so let's remove them to lessen potential
confusion and clutter. Also update the docs to make it clear how to
get hold of an unwrapped PHP if needed.
