[Buildroot] [PATCH v8 0/9] Add support for the Rust programming language

[Eric Le Bihan]

This series adds support for the Rust programming language by adding the
following packages:

 - rustc: a virtual package for the Rust compiler.
 - rust-bin: provides a pre-built version of rustc.
 - cargo-bin: provides a pre-built version of Rust package manager.
 - rust: builds rustc from source.
 - cargo: builds Rust package manager from source.
 - rust-cargo: a virtual package for the Rust package manager.

Only the host variants are provided.

The rustc and rust-cargo virtual packages are inspired by the mysql one.

v7 -> v8:

 - replace cargo-bootstrap by cargo-bin
 - drop rust-bootstrap and use rust-bin instead
 - rust-bin and rust versions are the same
 - cargo-bin and cargo versions are the same
 - bump cargo to 0.23.0
 - bump rust to 1.22.1
 - add rust-cargo virtual package

v6 -> v7:

 - add cargo 0.20.0
 - bump rust to 1.19.0
 - bump rust-bootstrap to 1.18.0
 - bump cargo-bootstrap to 0.19.0
 - bump rust-bin to 1.19.0
 - fix mips64 target name in rustc

v5 -> v6:

 - bump rust to 1.18.0
 - bump rust-bootstrap to 1.17.0
 - bump rust-bin to 1.18.0

v4 -> v5:

 - add rustc virtual package
 - add rust-bin, provider for rustc
 - rework rust to be a provider for rustc
 - rework some commit messages

v3 -> v4:

 - bump rust to 1.16.0
 - bump rust-bootstrap to 1.15.1
 - add cargo-bootstrap
 - use built-in target specifications
 - drop external Python script to generate target specifications
 - enable support for PowerPC
 - expose host variant in menuconfig

v2 -> v3:

 - bump rust to 1.10.0
 - rework and bump rust-bootstrap to 1.9.0
 - host-rust requires at least GCC 4.7 because of LLVM (suggested by R. Naour)
 - rust requires a glibc-based cross-compiler
 - rust requires GCC 5.x or above for Aarch64

v1 -> v2:

 - bump rust to version 1.9.0.
 - drop patch for bzip2 support in host-python.
 - add package for jemalloc.
 - add dependency on host being a x86 machine.
 - add dependency on toolchain.
 - use dedicated package to provide bootstrapping binary: rust-bootstrap.
 - let ./configure find out host/build on its own.
 - remove entry from configuration menu.

[Buildroot] [PATCH 1/9] rustc: new virtual package

[Eric Le Bihan]

The compiler for the Rust programming language is called rustc.

There is only one reference implementation for it, based on LLVM, from
the Rust project [1]. It can generate code for various architectures so
it can be labeled as a cross-compiler. But, as for GCC, building it
from source takes time.

So it would be sensible to have at least one package which provides it
as a pre-built version, fetched from the upstream project. Later another
package can be added, to build it from source code.

In addition to the compiler, the standard library for the host and/or
the target should also be fetched/built.

So, add a virtual package named rustc to enable support for multiple
providers.

Currently, only the host variant will be available to allow the user to
cross-compile Rust programs for the target.

[Buildroot] [PATCH 2/9] rust-bin: new package

[Eric Le Bihan]

This package provides a pre-built version of rustc, the compiler for the
Rust programming language, fetched from the upstream project.

A pre-built version of the standard library for the host as well as one
for the chosen target are also fetched and installed.

Only the host variant is provided to allow the user to cross-compile
Rust programs and run them on the target.

The menuconfig entry for rustc is also updated to expose this provider.

[Buildroot] [PATCH 8/9] cargo: new package

[Eric Le Bihan]

This new package provides Cargo, the Rust official package manager.
Cargo is written in Rust and uses Cargo as its build system. It also
depends on other Rust packages.

Normally, a previously installed version of Cargo would be used to:

 1. Fetch the dependencies.
 2. Build the new version of Cargo, using the available Rust compiler.

But the fetching step prevents offline builds. So instead two features
of Cargo are levelled: vendoring [1] and local registry.

First, a tarball of the build dependencies generated using `cargo
vendor` is fetched along with Cargo source code.

Then, the build process is as follows:

 1. The tarball of the build dependencies is uncompressed in a local
    registry.
 2. A snapshot of Cargo, provided by cargo-bin, builds the final
    version of Cargo.
 3. A configuration file telling Cargo how to cross-compile programs for
    the target is generated and installed.

Currently, only the host variant is provided.

[Buildroot] [PATCH 9/9] rust-cargo: new virtual package

[Eric Le Bihan]

Add a new host virtual package to provide Cargo, the package manager for
the Rust language.

Currently, two providers are available: host-cargo and host-cargo-bin.

Also remove host-cargo from menuconfig.

One patch of this series adds a package to build rust from source. It
contains a patch to remove *.orig files from usptream tarball and patch
some checksum files which list these files (used by Cargo).

Unfortunately, one of these checksum files has a line which exceeds 998
characters, which does not make git-send-email happy. I sent the patch
series using --no-validate, but this may not make all mail clients (or
mailman) happy too!

Should I resent as attachment instead?

What about --with-ssl=...? Isn't that needed for the linking with 
host-openssl?

This patch didn't make it to the list, because it is too large (2.48

The patch which adds the package to build Rust from source provides a 
patch to fix a problem involving files ending with *.orig.

As the Rust compiler is built using Cargo, the tarball contains vendored
versions of the crates (e.g. src/vendor/backtrace-sys). Each crate 
contains a file named Cargo.toml.orig. An associated file named
.cargo-checksum.json will contain a checksum for Cargo.toml.orig (and
the other source files).

But support/scripts/apply-patches.sh will delete the Cargo.toml.orig 
files. This will cause the build to fail, as Cargo will not be able to 
find the file and verify the checksum.

So the patch included in the rust package removes all Cargo.toml.orig 
entries from the affected .cargo-checksum.json. As these files list all
the source files, this results in a huge patch.

Besides, as these are non-indented JSON files, some are one-lined and 
thus the 998 characters limit enforced by git-send-email is exceeded.

So, if there a way to stop support/scripts/apply-patches.sh from pruning
Cargo.toml.orig files, so this patch can be dropped?

Do we really have a reason to remove *.orig files in
apply-patches.sh ? .orig backup files are only produced if -b is passed
to patch, which we are not using.

Are there other cases where .orig files are produced by patch *and* we
really need to remove them?

Peter, Arnout, Yann?

Now that I think of it, adding a post-extract hook to remove the
Cargo.toml.orig entries from .cargo-checksum.json files may do 
the trick... No more big patch nor apply-patches.sh modifications.

I have no idea about this, but the removal of .orig file has been there
since the dawn of ages, more than 15 years ago now, and the reason is
not explained.

I think we could very well live with .orig files, though.

Alternatively, we could set and export SIMPLE_BACKUP_SUFFIX=.orig.br (or
to any other singling-out value) which will force the backup suffix just
in case, and then we only remove those files.

Yet, this is adding a bit of complexity, when we could probably lives
happy with .orig files.

Except I suspect some badly-behaving packages could very well do things
like:

    data:
        call_my_tool $(wildcard #(top_srcdir)/data/*)

and thus, if we happen to patch a file in the data/ subdir, we'd break
the build of that package.

So, I would go for not removing .orig files, and in case there is one
package where this causes a problem, either we fix it, or we add a
post-patch hook to remove the .orig files, or we switch to using the
SIMPLE_BACKUP_SUFFIX variable if too many packages are impacted.

Deal? ;-)

Yann E. MORIN.

Though the configuration script properly detects the openssl library and
enables support for it, it is true that it might be better to explicitly
enable it. I'll add this in the next spin. Thanks.
