[Bug]: protoc-gen-validate@1.2.1 regressed the usage of rules_python resulting in a breaking change for later releases

[qtica]

What happened?

The latest protoc-gen-validate@1.2.1 introduced in #3783 changed the behavior of utilizing rules_python's extensions. The pip.parse was changed from hub_name to name.

A later release of rules_python removed the name attribute from pip.parse. This regression of the attribute in the MODULE.bazel makes it impossible to upgrade to later rules_python versions with the new protoc-gen-validate@1.2.1 version without patching.

Version

Development (host) and target OS/architectures: linux/linux

Output of bazel --version: 7.4.1

Version of relevant rules from the WORKSPACE or MODULE.bazel file: rules_python@1.2.0-rc0

Language(s) and/or frameworks involved:

rules_python@1.2.0-rc0

How to reproduce

In a MODULE.bazel file:

bazel_dep(name = "protoc-gen-validate", version = "1.2.1")
bazel_dep(name = "rules_python", version = "1.2.0-rc0")

Then run:

bazel mod deps --lockfile_mode=update

You will get an error about an unknown attribute name in pip.parse.

Any other information?

Additionally the version of rules_python was downgraded in this release's MODULE.abzel file, as well as the configuration for rules_python's extensions. These changes do not matter so much to me, but I do find it odd to move versions backwards in a newer release. But the main issue is just the regression of hub_name to name.

Would you be interested in sending a fixed version as e.g. 1.2.1.bcr.1? You could also add yourself as a module maintainer (you don't need to be an upstream maintainer for that) so that you will be asked to review new versions.
