Spin public developer meeting

Monday, 1:30-2:30 pm PDT

Monday, June 13th

template version affinity
- Ivan summarizing the proposal and complications involved with #556.
- Primrarily a concern for template maintainers
- Original user issue: https://github.com/fermyon/spin/issues/517
Spin state SIP
- tl;dr Proposal to expose logs and other metadata to the outside world.
- Focus is on logs for now as a host feature (i.e. mount wasi file into the component environment)
- Future goal is to enable an introspection interface
Spin v0.3
- Includes usability and ergonomic improvments and work to mitigate the ubuntu installation issue
  - https://github.com/fermyon/spin/issues/498
  - https://github.com/fermyon/spin/issues/539
- For linux, statically linking in required version of openssl is happy path
Component Model
- Traditionally, Spin has dependended on module linking (via use of wit-bindgen), however the latest version of wasmtime doesn't support component linking. Goal is to update to latest version of wit-bingen and wasmtime where module linking is still supported.
- Relevant PR:
  - https://github.com/bytecodealliance/wit-bindgen/pull/239
- As expected, the component model is a breaking change for the spin ecosystem and the spin developers will attempt to adapt as cohesively as possible to minimize the user / developer pain.
- "hostage to fortune"
- Implementation for wasmtime support of component model is well-underway (landing in next few releases)
- Exciting Go work for Host
