# [1.0.0-alpha.2](https://git.gitlab.arm.com/bazel/rules_toolchain/compare/v1.0.0-alpha.1...v1.0.0-alpha.2) (2023-11-16)

### Bug Fixes

* **resolved:** forward on `basename` attribute ([e71e807b](https://git.gitlab.arm.com/bazel/rules_toolchain/commit/e71e807b6ded13a3baf2d430900f675a1f8849fd))
* **test:** correctly output `stderr` from toolchain executable on error ([22cd1081](https://git.gitlab.arm.com/bazel/rules_toolchain/commit/22cd108126e8917d7142d7f447fdc61f69ea2521))

### Features

* **local_which:** make local binaries non-mandatory ([5d9a292c](https://git.gitlab.arm.com/bazel/rules_toolchain/commit/5d9a292cfd4a7f9dd5b952ca33c34b01da0fc796))

This allows the implicit `:resolved` target to be used even when the
local binary is not provided.

Technically, we can avoid that because one could set up both `local`
_and_ `resolved` repository rules. That is a boilerplate pain though.

This moves the error to execution time which is a bit of a pain.

Previously, because the repository was only resolved when a target
explicitly requested the local toolchain the error would be caught
before execution time. However, moving the convenience `:resolved`
target into the `local` repository nullifies that because the
repository needs to be resolved for _any_ toolchain because the
`:resolved` target is re-used.

The trade-off here seems worth it for simple `MODULE.bazel`
repository definitions.

Allows setting up resolved toolchains for multi-call binaries.

Implements a nice label in the release page for the source archive.

This removes the need for a custom `resolved` rule for every toolchain.

Upgrade path is to add the `toolchain_type` to the local repository
rule in `MODULE.bazel` and change the `resolved` target to an alias.

A `toolchain_resolved` repository rule is added as well for toolchains
that do not use local binaries.

This patch hugely simplifies the creation of toolchains downstream.

The default is to set files as executable in repository rules.

We often do not want that.

Especially disabling legacy runfiles.

`use_repo_rule` is available in `6.4.0` and above.

It _hugely_ simplifies what we want to do.

That should be the new minimum version for our rulesets.

As of writing, `6.4.0` is not released. The release candidates do not have
the `use_repo_rule` added, yet. Most rules use `last_rc` Bazel version.

`visibility` is available in 6.0+.

Adds an tag class that can select a repository based on the current local machine triplet.

For some reason, the `triplet:test` target creates all the Posix shell
scripts for each triplet.

We need a more efficient `triplet` rule implementation.

We also need to figure out why every single triplet is getting resolved.

It is almost impossible to correctly transfer all the local files necessary
for a local binary to the remote service.

For safety, constraint all local toolchains to run on the local client until we
have more time to validate that local toolchains work remotely.

This is certainly possible: C/C++ toolchain define all the local files needed
for remote execution.

We will need to expose the `data` attribute through so that arbitary files can
be globbed and sent along with the binary.
