This was a source of massive confusion for me when I first learned my way around nixpkgs' rust machinery. I seek to save others from that confusion.
* `buildRustPackage` should have been named `buildRustPackageUsingCargo`
* `buildRustCrate` should have been named `buildRustPackageUsingNix`
It is, unfortunately, too late to fix this. Let's do the next best thing and make the names `buildRustPackage` and `buildRustCrate` very prominent in the documentation, so readers see immediately that they need to learn the following jargon:
* `buildRustPackage` means "build this Rust crate by calling `cargo` in one (or two) monolithic derivations"
* `buildRustCrate` means "build this Rust crate by calling `rustc` in one derivation for each crate"
Fixes#186752. This adds buildVMMemorySize (defaults to 512 MiB) to
buildImage, which is passed to vm.runInLinuxVM. This is needed for
larger base images, which may otherwise cause container build failures
due to OOM in the VM.
Python package sets can be overridden by overriding an interpreter
and passing in `packageOverrides = self: super: {...};`. This is fine
in case you need a single interpreter, however, it does not help you
when you want to override all sets.
With this change it is possible to override all sets at once by
appending a list of "extensions" to `pythonPackagesExtensions`.
From reading the implementation you might wonder why a list is used, and
not
`lib.composeExtensions`? The reason is the latter requires knowledge of
the library function. This approach should be easier for most users
as it is similar to how we append to lists of e.g. inputs or patches
when overriding a derivation.
This section was broken out into its own file in efb55d2a42 but
apparently never actually got included anywhere.
Since then a more detailed section on using unfree packages has been
introduced.
Copied the introduction and removed the rest of the file.
This change mimics existing strip{All,Debug}List variables to
allow special stripping directories just for Target.
The primary use case in mind is gcc where package has to install
both host and target ELFs. They have to be stripped by their own
strip tools accordingly.
