mamba failed to parse complicated re package spec as conda

[holymonson]

Troubleshooting docs

• My problem is not solved in the Troubleshooting docs

Anaconda default channels

• I do NOT use the Anaconda default channels (pkgs/* etc.)

How did you install Mamba?

Mambaforge or latest Miniforge

Search tried in issue tracker

#1853

Latest version of Mamba

• My problem is not solved with the latest version

Tried in Conda?

I do not have this problem with Conda, just with Mamba

Describe your issue

Here is a complicated package spec libblas[build=^.*(accelerate|mkl)$], conda could parse it correctly and give libblas-3.9.0-21_osx64_accelerate, while mamba wrongly gives libblas-3.9.0-21_osx64_openblas. It seems mamba simply omitted those selectors.

Do the selectors work when not using regexes but simple wildcards?

Hello, yes I can confirm this is not implemented, neither in libolv, nor (yet) in our replacement.

[jaimergp]

This is a duplicate of #1853.

I submitted a PR for libsolv at openSUSE/libsolv#506, but it never received attention.

[jonashaag]

Try pinging the maintainer, worked for me

[AntoinePrv]

We'll soon be able to provided our own matchspec, so the PR is not strictly required.
(matchspecs inside repodata.json are still being adressed by libsolv for now, as we would need to investigate if our MatchSpec bring a performance hit).
