Conda installation of Ruff not running on aarch64

[bcaddy]

I'm trying to run Ruff on an NVIDIA Grace (i.e. ARM Neoverse v2) CPU and getting the following error:

<jemalloc>: Unsupported system page size
<jemalloc>: Unsupported system page size
memory allocation of 5 bytes failed
Aborted

This appears to be a reappearance of the page size issue noted in #3791 and I'm not sure how to fix it. I've installed Ruff with Conda from the Conda-forge channel and I'm on the latest version. Any suggestions?

Do you know if Ruff installs a pre-built wheel or is it installed from source?

Do you know what page size your system uses?

[bcaddy]

The page size is 64k and I'm just installing it with conda install -c conda-forge ruff.

I tried with the exact same version of Ruff installed via pip and it works just fine, so the issue is not actually with Ruff but with the version built/installed with Conda; I've updated the title accordingly.

Presumably we need to set this variable over in the conda-forge builds?

[MichaReiser]

Yes, I can take a look. @zanieb do you know who has access to our conda forge recipe and how it can be changed?

Anyone can open a pull request https://github.com/conda-forge/ruff-feedstock

[MichaReiser]

@bcaddy would you be interested in PRing a fix? It's on my todo list but it probably takes me a while before I get to and I have no prior conda forge knowledge

[bcaddy]

I also have no experience with conda forge and don't see an obvious place to change the jemalloc setting so I opened an issue on the ruff feedstock, hopefully they can help out.
