## [1.0.2](https://git.gitlab.arm.com/bazel/toolchain_utils/compare/v1.0.1...v1.0.2) (2025-02-06)

### Bug Fixes

* allow four-part `uname -r` versions ([555a6740](https://git.gitlab.arm.com/bazel/toolchain_utils/commit/555a67407e3639c71356950f2d2151860ba2fb4f))
* **toolchain_test:** use `$@` rather than `${@}` ([c4020797](https://git.gitlab.arm.com/bazel/toolchain_utils/commit/c4020797351cd3f968c286e834b6a9720a579511))

`rules_python` expects `install_name_tool` to be available on the system.

This is not the case when MacOS does not have developer tools installed.

`rules_python` attempts to perform the following:

```
/usr/bin/install_name_tool -id @rpath/libpython3.11.dylib lib/libpython3.11.dylib
```

We should do either:

- Upstream support for hermetic `install_name_tool`
- Switch the runfiles test to `rules_go`

The latter is likely the best choice.

`${@}` syntax is not supported on Bash 3.2 which is the default on MacOS.

On WSL2, the kernel version is reported as a four-part version such as `5.15.167.4-microsoft-standard-WSL2`.

The extra part is the increment number that Microsoft put onto of the upstream kernel headers.

We drop the extra patch part to stay consistent.

This likely needs a follow-up series of patches to validate the detection under WSL.

### BREAKING CHANGES

* **info:** `toolchain_info#variable` now defaults to the basename of the target executable.

Previously the variable defaulted to the `name` attribute:

```py
go_binary(
    name = "abc,
)

toolchain_info(
    name = "def",
    target = ":abc",
    # variable = "DEF",
)
```

Now the rule defaults the basename of the target executable:

```py
go_binary(
    name = "abc,
)

toolchain_info(
    name = "def",
    target = ":abc",
    # variable = "ABC",
)
```

In most situations, this is the prefered default.

In cases where the name is the variable name wanted, the `variable` now needs to be added:

```py
go_binary(
    name = "abc,
)

toolchain_info(
    name = "def",
    target = ":abc",
    variable = "ABC",
)
```
* **info:** `toolchain_info` removes `ToochainInfo#env`.

Allowing access to the original `env` attribute of the `toolchain_info` target can result in unexpected errors. `env` is usual subject to Make variable and expand location expansion. The expansion is done in the scope of the original rule. Re-using the environment results in errors with miscalculated paths, etc.

If it is required to capture the environment variables for a binary, it is much better to use a rule that bakes the environment variables into the execution of the binary. This can be done with launcher scripts that write out the environment variables for later use.
* **info:** `variables` is no longer available on the `ToolchainInfo` generated by `toolchain_info`.

The `TemplateVariableInfo` is created in the scope of the `toolchain_info` rule. Using the provider in downstream rules that access the `ToolchainInfo` will no longer be relevant.

A `ToolchainInfo#variable` attribute is provided to reconstruct a `TemplateVariableInfo` in the scope of a downstream rule.
* **resolved:** The `resolved` repository rule has removed the `basename` attribute in favour or symlinking the binary directly.

This change prevents unwanted symlink basename changes which can prevent multi-tool binaries from functioning correctly.

To set the basename of a symlink use the `toolchain_symlink_target` rule.
* **toolchain_local_select:** `toolchain_local_select#map` is now flipped taking the labels as they keys rather than as the values.

Previous releases had the following setup:

```py
download_file(
    name = "abc-arm64-linux-gnu",
    output = "abc",
)

download_file(
    name = "abc-arm64-linux-musl",
    output = "abc",
)

toolchain_local_select(
    name = "abc",
    map = {
        "arm64-linux-gnu": "@abc-arm64-linux-gnu",
        "arm64-linux-musl": "@abc-arm64-linux-musl",
    },
)
```

This prevented eagarly overfetching all the repositories that would be
selected. As of Bazel 7.4.0+[1], it no longer overfetches so the `map`
attribute has been switched to a `label_keyed_string_dict`:

```py
toolchain_local_select(
    name = "abc",
    map = {
        "@abc-arm64-linux-gnu": "arm64-linux-gnu",
        "@abc-arm64-linux-musl": "arm64-linux-musl",
    },
)
```

The repository rule will _only_ fetch the repostory label that has been selected due
to the triplet value matching.

Whilst this is a breaking change, it will introduce a regression on Bazel 7.3 and below
which will overfetch the repositories. It is *highly* recommended to use Bazel 7.4 and above.

* `ToolchainInfo#inherited` removed

It is not possible to use these in an action as the host
environment variables cannot be read host environment variables.
* The `toolchain_symlink_target` no longer exports
`ToolchainInfo`/`TemplateVariableInfo`.

The `toolchain_info` can provide those providers. The `toolchain_symlink_target`
is purely for creating a symlink to a previous target. This still enables
changing the basename for multi-call binaries.

To gain the old functionality, if `basename` attribute is not being used,
`toolchain_symlink_target` can be switched directly for `toolchain_info`. If
`basename` is being used, an extra `toolchain_info` rule will need to be created
to wrap the `toolchain_symlink_target` rule.
* **symlink/target:** the `files_to_run` property has been removed from the `ToolchainInfo` provider. Use `info.default.files_to_run` instead.

A new `info.run` has been added that is `info.default.files_to_run` or `info.default.executable`.
This is a convenience property that can be passed to `ctx.actions.run#execute`.
* **symlink/target:** `toolchain_symlink_path` no longer provides `ToolchainInfo`/`TemplateVariableInfo`.

It is required to use `toolchain_symlink_target` to the `toolchain_symlink_path`.

This is due to `toolchain_symlink_target` needing to export the `DefaultInfo.file_to_run` from the
symlinked target. That is not possible with a filesystem path.

This should not affect most users as `toolchain_symlink_path` is mainly used in `toolchain_local_which`.

If `toolchain_symlink_path` is being used, then to gain the previous functionality, create a
`toolchain_symlink_target` to the `toolchain_symlink_path` label.

`toolchain_symlink_*` targets no longer export `ToolchainInfo`.

Removes `reuse` support in favour of `rules_license` to generate software bill of materials (SBOM).

There are unnecessary list comprehensions in the constraints that
have been flattened to raw aliases.

The default visibility has been removed in favour of explicitly setting
the visibility on each rule. This prevents accidental exporting of
constraints that are expected to be internal.

BREAKING CHANGE: `toolchain_info#variable` now defaults to the basename of the target executable.

Previously the variable defaulted to the `name` attribute:

```py
go_binary(
    name = "abc,
)

toolchain_info(
    name = "def",
    target = ":abc",
    # variable = "DEF",
)
```

Now the rule defaults the basename of the target executable:

```py
go_binary(
    name = "abc,
)

toolchain_info(
    name = "def",
    target = ":abc",
    # variable = "ABC",
)
```

In most situations, this is the prefered default.

In cases where the name is the variable name wanted, the `variable` now needs to be added:

```py
go_binary(
    name = "abc,
)

toolchain_info(
    name = "def",
    target = ":abc",
    variable = "ABC",
)
```

Avoids building during `bazel build ...`

BREAKING CHANGE: `toolchain_info` removes `ToochainInfo#env`.

Allowing access to the original `env` attribute of the `toolchain_info` target can result in unexpected errors. `env` is usual subject to Make variable and expand location expansion. The expansion is done in the scope of the original rule. Re-using the environment results in errors with miscalculated paths, etc.

If it is required to capture the environment variables for a binary, it is much better to use a rule that bakes the environment variables into the execution of the binary. This can be done with launcher scripts that write out the environment variables for later use.

It is renamed to `download_utils`

BREAKING CHANGE: `variables` is no longer available on the `ToolchainInfo` generated by `toolchain_info`.

The `TemplateVariableInfo` is created in the scope of the `toolchain_info` rule. Using the provider in downstream rules that access the `ToolchainInfo` will no longer be relevant.

A `ToolchainInfo#variable` attribute is provided to reconstruct a `TemplateVariableInfo` in the scope of a downstream rule.

The variable must point to an executable generated from this rule to work
in `genrule`'

This reverts commit f82eb108.

The resolved rule incorrectly rebuilt and forwarded on providers
in such a way that the variable was not able to be used in a `genrule`
because runfiles were not correctly found.

This patch resolves this issue by correctly constructing the providers.

BREAKING CHANGE: The `resolved` repository rule has removed the `basename` attribute in favour or symlinking the binary directly.

This change prevents unwanted symlink basename changes which can prevent multi-tool binaries from functioning correctly.

To set the basename of a symlink use the `toolchain_symlink_target` rule.

Allows redirecting the variable later, if needed.
