* Bump to 0.36.0 * Add a two-week delay to Wasmtime's release process This commit is a proposal to update Wasmtime's release process with a two-week delay from branching a release until it's actually officially released. We've had two issues lately that came up which led to this proposal: * In #3915 it was realized that changes just before the 0.35.0 release weren't enough for an embedding use case, but the PR didn't meet the expectations for a full patch release. * At Fastly we were about to start rolling out a new version of Wasmtime when over the weekend the fuzz bug #3951 was found. This led to the desire internally to have a "must have been fuzzed for this long" period of time for Wasmtime changes which we felt were better reflected in the release process itself rather than something about Fastly's own integration with Wasmtime. This commit updates the automation for releases to unconditionally create a `release-X.Y.Z` branch on the 5th of every month. The actual release from this branch is then performed on the 20th of every month, roughly two weeks later. This should provide a period of time to ensure that all changes in a release are fuzzed for at least two weeks and avoid any further surprises. This should also help with any last-minute changes made just before a release if they need tweaking since backporting to a not-yet-released branch is much easier. Overall there are some new properties about Wasmtime with this proposal as well: * The `main` branch will always have a section in `RELEASES.md` which is listed as "Unreleased" for us to fill out. * The `main` branch will always be a version ahead of the latest release. For example it will be bump pre-emptively as part of the release process on the 5th where if `release-2.0.0` was created then the `main` branch will have 3.0.0 Wasmtime. * Dates for major versions are automatically updated in the `RELEASES.md` notes. The associated documentation for our release process is updated and the various scripts should all be updated now as well with this commit. * Add notes on a security patch * Clarify security fixes shouldn't be previewed early on CI
wasi-common
A Bytecode Alliance project
A library providing a common implementation of WASI hostcalls for re-use in any WASI-enabled runtime.
The wasi-common crate will ultimately serve as a library providing a common implementation of
WASI hostcalls for re-use in any WASI (and potentially non-WASI) runtimes
such as Wasmtime and Lucet.
The library is an adaption of lucet-wasi crate from the Lucet project, and it is currently based on 40ae1df git revision.
Please note that the library requires Rust compiler version at least 1.37.0.
Supported syscalls
*nix
In our *nix implementation, we currently support the entire WASI API with the exception of socket hostcalls:
sock_recvsock_sendsock_shutdown
We expect these to be implemented when network access is standardised.
We also currently do not support the proc_raise hostcall, as it is expected to
be dropped entirely from WASI.
Windows
In our Windows implementation, we currently support the minimal subset of WASI API which allows for running the very basic "Hello world!" style WASM apps. More coming shortly, so stay tuned!
Development hints
When testing the crate, you may want to enable and run full wasm32 integration testsuite. This
requires wasm32-wasi target installed which can be done as follows using rustup
rustup target add wasm32-wasi
Now, you should be able to run the integration testsuite by running cargo test on the
test-programs package with test-programs/test_programs feature enabled:
cargo test --features test-programs/test_programs --package test-programs
