This is probably why the last tag was failing.

If we merge conda-forge/constructor-feedstock#61 we don't need this pip install override, right?

This will pull libmambapy plus its deps so I wonder if just the presence of mamba as a command is enough to justify the existence of Mambaforge. Like, if we merge, Miniforge and Mambaforge are almost the same. IIRC, Mambaforge was provided separately because it shipped more deps.

conda-forge/constructor-feedstock#61 was merged, so we can remove this in a couple hours.

A few notes on this:
Some context first: The new solver integration was released as a separate package as a means for users to "opt-in" into the experimental phase of the engineering effort, basically for us to be able to collect feedback from real world environments. The goal is to gain the confidence that our integration layer with libmamba indeed works as closely as possible to conda's default solver. It's not just a straight port of libmamba but does extra steps to be closer to what users expect from conda. The extra installation step was a design decision to make sure we're not accidentally cargo-cult the experimental solver into "production environments" such as conda-forge.
The miniconda 4.12.0 installer will not automatically install conda-libmamba-solver. It largely depends on the real world user feedback, but I'm expecting it to be added in the next release of miniconda at the end of Q2, start of Q3 time frame instead, when we hope to have finalized the experiment.
For conda-forge I would strongly suggest to wait for at least one or two bugfix releases before adding conda-libmamba-solver to miniforge, simply because it would make it easier for Jaime, Wolf and me to ship breaking changes in conda-libmamba-solver when they become necessary following user feedback.
Regarding mambaforge and how conda-libmamba-solver fits into this, I want to encourage us to think about this before we make decisions (like merging this PR here) before we regret it afterwards. mambaforge/miniforge and mamba are reasonable alternatives to miniconda and conda and I'd rather gain more experience with conda-libmamba-solver before we change the installers that a lot of users use.
The alternative to this PR right now is: conda install conda-libmamba-solver.
Could we maybe put this PR on hold for a bit?

IIUC sounds like we are now good to include Would we like to revitalize this PR or start a new one? |
|
@jakirkham - I added a comment on 284 to figure out how we want to move forward! Thanks for the reminder! |
|
Updated PR as discussed in #284. Note that I am not copying the installers yet. The name of the installer, as taken by I suggest we advertise this in the release notes and maybe in other channels (blog post, Twitter, Element, etc), and then change it to a copy in the next release or two. |

This is ready for review @conda-forge/miniforge. Thanks! |
|
FWIW LGTM. Thanks Jaime! 🙏 |
|
@hmaarrfk could you please take a look? |
|
Friendly nudge @hmaarrfk 😉 |
|
Sorry, trying to enable boa compatibility tests on miniforge too. |
|
Thanks everyone! 🙏 |
|
Release is now out. Give it a try! |
|
Thanks Mark! Looks like it's gone live in macOS and Windows and no one has complained in Element yet :D I have sent a PR to change the base Miniforge install in our Linux Docker images at conda-forge/docker-images#239 I also updated the release description a bit to add a couple extra details. Hope that's ok! |

Noticed the tag is 23.3.1. Am wondering if it should be 23.8.0 |

Ah nvm looks like the version is tied to how Conda & friends are versioned. Submitted PR ( #480 ) to address this
