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.
Some extensions depend on other extensions. Previously, these had to
be added manually to the list of included extensions, or we got a
cryptic error message pointing to strings-with-deps.nix, which wasn't
very helpful. This makes sure all required extensions are included in
the set from which textClosureList chooses its snippets.
Rework withExtensions / buildEnv to handle currently enabled
extensions better and make them compatible with override. They now
accept a function with the named arguments enabled and all, where
enabled is a list of currently enabled extensions and all is the set
of all extensions. This gives us several nice properties:
- You always get the right version of the list of currently enabled
extensions
- Invocations chain
- It works well with overridden PHP packages - you always get the
correct versions of extensions
As a contrived example of what's possible, you can add ImageMagick,
then override the version and disable fpm, then disable cgi, and
lastly remove the zip extension like this:
{ pkgs ? (import <nixpkgs>) {} }:
with pkgs;
let
phpWithImagick = php74.withExtensions ({ all, enabled }: enabled ++ [ all.imagick ]);
phpWithImagickWithoutFpm743 = phpWithImagick.override {
version = "7.4.3";
sha256 = "wVF7pJV4+y3MZMc6Ptx21PxQfEp6xjmYFYTMfTtMbRQ=";
fpmSupport = false;
};
phpWithImagickWithoutFpmZip743 = phpWithImagickWithoutFpm743.withExtensions (
{ enabled, all }:
lib.filter (e: e != all.zip) enabled);
phpWithImagickWithoutFpmZipCgi743 = phpWithImagickWithoutFpmZip743.override {
cgiSupport = false;
};

Make buildEnv take earlier overridden values into account by
forwarding all arguments (a merge of generic's arguments, all previous
arguments and the current arguments) to the next invocation of
buildEnv.
Make all arguments to a PHP build overridable; i.e, both configuration
flags, such as valgrindSupport, and packages, such as valgrind:
php.override { valgrindSupport = false; valgrind = valgrind-light; }
This applies to packages built by generic and buildEnv/withExtensions;
i.e, it works with both phpXX and phpXXBase packages.
The following changes were also made to facilitate this:
- generic and generic' are merged into one function
- generic now takes all required arguments for a complete build and
is meant to be called by callPackage
- The main function called from all-packages.nix no longer takes all
required arguments for a complete build - all arguments passed to it
are however forwarded to the individual builds, thus default
arguments can still be overridden from all-packages.nix
This implements the override pattern for builds done with buildEnv, so
that we can, for example, write
php.override { fpmSupport = false; }
and get a PHP package with the default extensions enabled, but PHP
compiled without fpm support.
