For consistency with other toolchains (and to save typing) I recommend naming this simply "toolchain_type".

Most of this file is the repository rule that autodetects the shell toolchain. Is it worth splitting the definition of the actual shell_toolchain rule to a separate .bzl file, so that people defining standalone shell toolchains aren't loading all of this?

Good point, done.

Also, and this isn't part of this change but a general comment, we need a general purpose library of repository functions for common tasks like os detection.

I'll fix up #5001 and submit it today to unblock you. |

Bazel automatically detects the local Bash and creates a custom toolchain rule for it. Later, rules that use Bash will require this toolchain and retrieve Bash's path from it instead of relying on hardcoded paths or the --shell_executable flag.

The assertion in line bazelbuild#235 passes on Linux if the limit is 9, on Darwin if it is 10. Commenting out the code in BazelRulesModule.java that automatically loads the sh_configure() rule which instantiates @local_config_sh makes the test pass with the old limit (8).
