"Category" bugs have been solved in recent versions of Polars (upgrade needed!)
I am unsure how involved the upgrade will be, but creating an issue to share what I found.
After finding data corruption when doing things like:
defmodule DataFrameAdapter do
@dtypes [
{:level, {:u, 8}},
{:node, :category},
{:text, :category},
{:attributes, {:list, {:struct, [name: :category, value: :category]}}}
]
where unit tests showed that the "value" field in our attributes were sometimes corrupt, I did a bit of digging.
It appears that the whole family of similar bugs has been fixed here:
- https://github.com/pola-rs/polars/pull/23016
Our version of Polars (rust crate) is set here:
https://github.com/elixir-explorer/explorer/blob/607ed7f92aa0f19bf348d5bbaae3be07bef92d1d/native/explorer/Cargo.toml#L30
I could not find release notes for the Rust crate (only for the Python library), but found out you can use tags here to compare, FWIW:
https://github.com/pola-rs/polars/compare/rs-0.49.0...rs-0.52.0
I started poking around with an upgrade to 0.50 : it is already a bit involved, but at a quick glance I believe it would include the category fixes.
Rust release notes are also in GitHub releases, mixed in with the Python releases, but there's so many Python releases that the rust ones get buried and hard to find. Here's direct links to all the releases since 0.49.1 https://github.com/pola-rs/polars/releases/tag/rs-0.50.0 https://github.com/pola-rs/polars/releases/tag/rs-0.51.0 https://github.com/pola-rs/polars/releases/tag/rs-0.52.0
I also started poking around with a upgrade to 0.50, but it is indeed a bit involved. There are 67 compile errors (29 after removing duplicates), and the release notes don't give any guidance on how to upgrade.

This is beyond my ability in rust to investigate and fix all of these on my own, but these categorical bugs have been bugging me a lot, and I'm willing to contribute if there's anything I can do to to help.
@skyqrose @thbar Apologies for the delayed responses! I've been working on some other life stuff and have fallen behind Explorer.
As you say, an upgrade to Polars 0.50 is quite involved. I tried an upgrade a little while back but my progress stalled when I realized that they'd completely redone their Category implementation. A decent portion of the Rust code will need to be rewritten to accommodate.
That said, @skyqrose if you want to push up your attempt I'll be happy to take a look.
I didn't make any progress. I just got far enough to see the compiler errors but didn't fix any of them.
