ucx() problem with versions with the suffix -rc

[lmagdanello]

What happens is that when using versions with the -rc suffix with the UCX building block, we encounter the following issue:

The module attempts to download the path: https://github.com/openucx/ucx/releases/download/v1.15.0-rc4/ucx-1.15.0-rc4.tar.gz. However, UCX provides the path for -rc versions in the following way: https://github.com/openucx/ucx/releases/download/v1.15.0-rc4/ucx-1.15.0.tar.gz.

Recipe:

Stage0 += ucx(version='1.15.0-rc4')

Log:

My idea is that with this simple regex, we can give users the freedom to use pre-release versions.

Does this work?

Stage0 += ucx(url='https://github.com/openucx/ucx/releases/download/v1.15.0-rc4/ucx-1.15.0.tar.gz')

[lmagdanello]

Yes, but in theory we could natively support pre-release versions, as they are provided in the UCX default repository.

[lmagdanello]

I was thinking about my suggestion and thought of another solution: perhaps the UCX building block can receive _prerelease as a parameter and if it is True it will deal with versions with the -rc suffix. What do you think?

[samcmill]

I am concerned about maintaining the pre-release logic.

Since there is a straightforward workaround using the url parameter, I'm inclined not to try to fix this.

[lmagdanello]

Of course, I understand. I'll close the issue in this case then.
