Hmm okay, you sound like you are giving up on this :) I know how many hours (we probably need to measure those in days or even weeks) you have spent on this though. Let’s pool resources together and finally get this done.

As most packages are bundling all Rust deps, there should be some we won’t need any more in the system. Then, we hopefully have much less to update/worry about in any other way when we start touching python-cryptography. So who is volunteering to do this? Commenting out all Rust packages, then build python-cryptography which will fail as it requires some Rust crates. Those will be there so they will only have to be commented in again. Once the package builds, we should then have a couple of packages still commented that we can drop. > I think a problem moving forward is that more python modules are ending up > being a combination of python and rust as the cryptography and maturin > modules have already done.

Yes it does, but we will have to find a way whether we want it or not. -Michael > Regards, > > Adolf. > > >> All the best, >> -Michael >>> On 22 Jan 2026, at 17:38, Stefan Schantl <[email protected]> wrote: >>> >>> Hello list followers, >>> >>> I'm currently updating rust and affected modules. >>> >>> This happends mainly because I'm trying to fix the "suricata cache >>> grows infinite" problem, which a lot of people are affected. >>> >>> To archive this, I ported the patches from suricata main development >>> branch to our used suricata version (8.0.3). >>> >>> To perform a full build, a new tool called cbindgen - which is a rust >>> to c bindings generator, is required. >>> >>> Sadly this tool is also written in rust and requires some new >>> dependencies and a more up to date rust compiler. >>> >>> I hope to send a patchset for all this very soon to the mailing list. >>> >>> Best regards, >>> >>> -Stefan
