is there a lock file version / pixi version map exists?

[trim21]

I'm currently working on adding pixi support for https://github.com/renovatebot/renovate, which is a dependency automation tool.

There is a need to refresh user's lock file after it update pixi.toml to keey repo's pixi config files in a valid state. And it whould be best to generate same version of pixi lock file so it doesn't break user with old toolchain.

Is there a lock file pixi version map so I can know which version of pixi should I install based on the version of lockfile?

for example, if it's a pixi.lock with version: 5, what's the latest version of pixi should I pick to generate lock?

I think this is related to #1061 , which pixi version a user should pick based on pixi.toml and pixi.lock.

also : #2278

Current result: #3187 (reply in thread)

It's not a issue if we don't have such thing, always use latest pixi and generate latest lock file is also a acceptable solution, (like uv).

There is currently no map or automation to check the version, apart from pixi giving you the error if it doesn't fit.

Ps. I'm excited about the renovate work!

Yeah, that's extractly the error I want to avoid....

Would you mind help me with when we start to generate lock file version 6 instead of 5? before 4 maybe too old and I'm not planing to support then.

you should be able to relatively easily construct this mapping yourself by repeatedly trying pixi exec -s pixi=<custom-pixi-version> -- pixi list and see where it starts failing.
You can write a small shell script that gets all github releases using pixi exec gh release list -R prefix-dev/pixi --json tagName

you can use pixi exec micromamba search pixi --json | jq -r '.result.pkgs[].version'. pixi search --json is something @delsner and i want to tackle at some point

I'm using github api and download releases from github now

latest pixi still support lock file version 1 so I didn't which lock file version it support, it should support any version less or equal than it generated

a more readable result:

lock version	pixi version
1	<= 0.6.0
2	== 0.7.0
3	>= 0.8.0, <= 0.12.0
4	>= 0.13.0, <= 0.20.1
5	>= 0.21.0, <= 0.38.0
6	>= 0.39.0

But I don't want to submit a PR for it....
