From 2ecbf48820253f83f240f6a03ba6e5a3985acfd0 Mon Sep 17 00:00:00 2001 From: Eduardo de Moura Rodrigues <16357187+eduardomourar@users.noreply.github.com> Date: Mon, 11 Sep 2023 18:58:45 +0200 Subject: [PATCH] feat(wasmtime-cli): restore support for wasi http module (#6878) (#6974) * feat(wasmtime-cli): add async support flag Within the wasmtime CLI, the current default behavior is to only inject the synchronous functions to linkers. This will add a flag called `--async` that will inject the asynchronous one instead. * chore: refactor wasi http crate * feat(wasmtime-wasi): make in_tokio function public * feat(wasi-http): define default feature called sync * Revert "feat(wasmtime-cli): add async support flag" This reverts commit b743ff2003a2e391972330aa8e8437c6356e580a. * chore: improve flaky tests for wasi http * feat(wasi-http): expose sync api for components * chore: add tests for sync api of wasi http components * feat(wasmtime-cli): restore support for wasi http module * chore: revert change to outbound http request invalid test * chore: have extra tracing to help debugging * feat(wasi-http): allow modules with sync functions in linker * fix(wasi-http): missing response body in sync api * feat: include blocking for io streams * chore: add tests for wasi http module in cli * chore: disable preview2 flag in wasi http test * chore: use preview2 flag in wasi http test * fix(wasi-http): missing stream output in sync api * chore: fix tests for wasi http * chore: add tracing for poll oneoff call * chore: send exit signal on wasi http test * chore: swap println to tracing debug * chore: set http server timeout to 50 secs by default * chore: add test posting large file * chore: revert formatting in cargo toml * chore: fix wasi-http feature and skip failing tests prtest:full ---------
