From 9b2c65753ff308df36f832d77c453e8502aef7ee Mon Sep 17 00:00:00 2001 From: Joel Dice Date: Wed, 13 Dec 2023 14:27:14 -0700 Subject: [PATCH] add support for `wasi:http/incoming-handler@0.2.0-rc-2023-11-10` (#2166) * add support for `wasi:http/incoming-handler@0.2.0-rc-2023-11-10` This builds upon Alex's excellent work in https://github.com/fermyon/spin/pull/2108, adding the ability to run guests which target the `0.2.0-rc-2023-11-10` version of `wasi-http`. I've added a test which uses `wit-bindgen` and `wit-component` directly to ensure it uses the correct snapshot for everything `wasi-http`, `wasi-cli`, etc. Note that we're not yet updating any SDKs to use the new snapshot, since we still want people to be able to use the new SDK to target Spin 2.0. Signed-off-by: Joel Dice * use different names for `wasi-http-rust-rc-2023-11-10` module and component Previously, I tried to be clever and overwrite the module with the component, but that led to a filesystem-level race condition and was just generally fragile.
