since Google doesn't help I'm pretty sure there is no well-traveled path but has anyone looked into this yet?
Joel Dice (Jul 03 2023 at 13:40):You might want to look at componentize-py and/or spin-python-sdk, both of which use Py03 to bridge Rust and Python in a WASI guest. The key to making it work is building CPython to target WASI and setting the lib_dir option in your Py03 config file to point to it, e.g. https://github.com/dicej/componentize-py/blob/7f7489dcae8104f501902854a901394c8a17c4c3/build.rs#L222-L248.
Ramon Klass (Jul 03 2023 at 14:44):oh I didn't realize componentize actually uses pyo3, thank you I will have a deeper look :)
side question, is there any update on supporting the new wit format with packages?
Joel Dice (Jul 03 2023 at 15:31):The snapshot branch in the componentize-py repo uses the new WIT format, but that branch also includes native extension support (i.e. the "pseudo-dynamic linking" stuff I mentioned above), which depends on toolchain changes which haven't been upstreamed yet. I'm hoping to work on that later this week. The WIT-related changes could probably be backported to the main branch, but I'm not sure that's worth the effort.
Ramon Klass (Jul 03 2023 at 15:53):I agree backporting is too much effort, thanks a lot for the progress report :) I hope upstream merges will go smoothly
Notification Bot (Jul 03 2023 at 16:14):Ramon Klass has marked this topic as resolved.
Robin Brown (Jul 10 2023 at 19:34):@Ramon Klass if you're interested in keeping up with the progress on Python. @Joel Dice and @Kevin Smith are the organizers of the Python Subgroup of the Guest Languages SIG and they meet as a group on an every other week cadence to talk about Python guest work.
Ramon Klass (Jul 11 2023 at 14:55):I'm generally interested, I wasn't sure how open those meetings are and never dared to sign up for one
Ralph (Jul 11 2023 at 16:53):no harm in dropping in to find out!
Jamey Sharp (Jul 11 2023 at 19:09):I'd love to see more interested folks show up!
Robin Brown (Jul 11 2023 at 19:28):All meetings for SIG Guest Languages and its subgroups are fully open to the public. You're welcome to join us!
