* wiggle: no longer need to guard wasmtime integration behind a feature
this existed so we could use wiggle in lucet, but lucet is long EOL
* replace wiggle::Trap with wiggle::wasmtime_crate::Trap
* wiggle tests: unwrap traps because we cant assert_eq on them
* wasi-common: emit a wasmtime::Trap instead of a wiggle::Trap
formally add a dependency on wasmtime here to make it obvious, though
we do now have a transitive one via wiggle no matter what (and therefore
can get rid of the default-features=false on the wiggle dep)
* wasi-nn: use wasmtime::Trap instead of wiggle::Trap
there's no way the implementation of this func is actually
a good idea, it will panic the host process on any error,
but I'll ask @mtr to fix that
* wiggle test-helpers examples: fixes
* wasi-common cant cross compile to wasm32-unknown-emscripten anymore
this was originally for the WASI polyfill for web targets. Those days
are way behind us now.
* wasmtime wont compile for armv7-unknown-linux-gnueabihf either
* Leverage Cargo's workspace inheritance feature
This commit is an attempt to reduce the complexity of the Cargo
manifests in this repository with Cargo's workspace-inheritance feature
becoming stable in Rust 1.64.0. This feature allows specifying fields in
the root workspace `Cargo.toml` which are then reused throughout the
workspace. For example this PR shares definitions such as:
* All of the Wasmtime-family of crates now use `version.workspace =
true` to have a single location which defines the version number.
* All crates use `edition.workspace = true` to have one default edition
for the entire workspace.
* Common dependencies are listed in `[workspace.dependencies]` to avoid
typing the same version number in a lot of different places (e.g. the
`wasmparser = "0.89.0"` is now in just one spot.
Currently the workspace-inheritance feature doesn't allow having two
different versions to inherit, so all of the Cranelift-family of crates
still manually specify their version. The inter-crate dependencies,
however, are shared amongst the root workspace.
This feature can be seen as a method of "preprocessing" of sorts for
Cargo manifests. This will help us develop Wasmtime but shouldn't have
any actual impact on the published artifacts -- everything's dependency
lists are still the same.
* Fix wasi-crypto tests
This commit replaces #4869 and represents the actual version bump that
should have happened had I remembered to bump the in-tree version of
Wasmtime to 1.0.0 prior to the branch-cut date. Alas!
* Upgrade all crates to the Rust 2021 edition
I've personally started using the new format strings for things like
`panic!("some message {foo}")` or similar and have been upgrading crates
on a case-by-case basis, but I think it probably makes more sense to go
ahead and blanket upgrade everything so 2021 features are always
available.
* Fix compile of the C API
* Fix a warning
* Fix another warning
* 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
* Adjust dependency directives between crates
This commit is a preparation for the release process for Wasmtime. The
specific changes here are to delineate which crates are "public", and
all version requirements on non-public crates will now be done with
`=A.B.C` version requirements instead of today's `A.B.C` version
requirements.
The purpose for doing this is to assist with patch releases that might
happen in the future. Patch releases of wasmtime are already required to
not break the APIs of "public" crates, but no such guarantee is given
about "internal" crates. This means that a patch release runs the risk,
for example, of breaking an internal API. In doing so though we would
also need to release a new major version of the internal crate, but we
wouldn't have a great hole in the number scheme of major versions to do
so. By using `=A.B.C` requirements for internal crates it means we can
safely ignore strict semver-compatibility between releases of internal
crates for patch releases, since the only consumers of the crate will be
the corresponding patch release of the `wasmtime` crate itself (or other
public crates).
The `publish.rs` script has been updated with a check to verify that
dependencies on internal crates are all specified with an `=`
dependency, and dependnecies on all public crates are without a `=`
dependency. This will hopefully make it so we don't have to worry about
what to use where, we just let CI tell us what to do. Using this
modification all version dependency declarations have been updated.
Note that some crates were adjusted to simply remove their `version`
requirement in cases such as the crate wasn't published anyway (`publish
= false` was specified) or it's in the `dev-dependencies` section which
doesn't need version specifiers for path dependencies.
* Switch to normal sever deps for cranelift dependencies
These crates will now all be considered "public" where in patch releases
they will be guaranteed to not have breaking changes.
* wasi-common: update wasi submodule
This updates the WASI submodule, pulling in changes to the witx crate,
now that there is a 0.9.1 version including some bug fixes. See
WebAssembly/WASI#434 for more information.
* wiggle: update witx dependencies
* publish: verify and vendor witx-cli
* adjust root workspace members
This commit removes some items from the root manifest's workspace
members array, and adds `witx-cli` to the root `workspace.exclude`
array.
The motivation for this stems from a cargo bug described in
rust-lang/cargo#6745: `workspace.exclude` does not work if it is nested
under a `workspace.members` path.
See WebAssembly/WASI#438 for the underlying change to the WASI submodule
which reorganized the `witx-cli` crate, and WebAssembly/WASI#398 for the
original PR introducing `witx-cli`.
See [this
comment](https://github.com/bytecodealliance/wasmtime/pull/3025#issuecomment-867741175)
for more details about the compilation errors, and failed alternative
approaches that necessitated this change.
N.B. This is not a functional change, these crates are still implicitly
workspace members as transitive dependencies, but this will allow us to
side-step the aforementioned cargo bug.

Implement Wasmtime's new API as designed by RFC 11. This is quite a large commit which has had lots of discussion externally, so for more information it's best to read the RFC thread and the PR thread.
async methods used by wiggle currently need to Not have the Send
constraint, so rather than make all use sites pass the argument
to the re-exported async_trait macro, define a new macro that
applies the argument.
This commit updates to the 0.9 version of the witx crate implemented in
WebAssembly/wasi#395. This new version drastically changes code
generation and how we interface with the crate. The intention is to
abstract the code generation aspects and allow code generators to
implement much more low-level instructions to enable more flexible APIs
in the future. Additionally a bunch of `*.witx` files were updated in
the WASI repository.
It's worth pointing out, however, that `wasi-common` does not change as
a result of this change. The shape of the APIs that we need to implement
are effectively the same and the only difference is that the shim
functions generated by wiggle are a bit different.
* Add AArch64 tests to CI
This commit enhances our CI with an AArch64 builder. Currently we have
no physical hardware to run on so for now we run all tests in an
emulator. The AArch64 build is cross-compiled from x86_64 from Linux.
Tests all happen in release mode with a recent version of QEMU (recent
version because it's so much faster, and in release mode because debug
mode tests take quite a long time in an emulator).
The goal here was not to get all tests passing on CI, but rather to get
AArch64 running on CI and get it green at the same time. To achieve that
goal many tests are now ignored on aarch64 platforms. Many tests fail
due to unimplemented functionality in the aarch64 backend (#1521), and
all wasmtime tests involving compilation are also disabled due to
panicking attempting to generate generate instruction offset information
for trap symbolication (#1523).
Despite this, though, all Cranelift tests and other wasmtime tests
should be runnin on AArch64 through QEMU with this PR. Additionally
we'll have an AArch64 binary release of Wasmtime for Linux, although it
won't be too useful just yet since it will panic on almost all wasm
modules.

* wiggle-generate: paramaterize library on module path to runtime
This change makes no functional difference to users who only use the
wiggle crate.
Add a parameter to the `Names` constructor that determines the module
that runtime components (e.g. GuestPtr, GuestError etc) of wiggle come
from. For `wiggle` users this is just `quote!(wiggle)`, but other
libraries which consume wiggle-generate may wrap and re-export wiggle
under some other path, and not want their consumers to have to know
about the wiggle dependency, e.g. `quote!(my_crate::some_path::wiggle)`.
* wiggle-generate,macro: move more logic into macro
better for code reuse elsewhere
* Wasmtime 0.15.0 and Cranelift 0.62.0. (#1398)
* Bump more ad-hoc versions.
* Add build.rs to wasi-common's Cargo.toml.
* Update the env var name in more places.
* Remove a redundant echo.
* Move back to only one WASI submodule
This commit fixes the issue where we have two WASI submodules for build
reasons in this repository. The fix was to place the submodule in the
`wasi-common` crate, and then anyone using the `wig` crate has to be
sure to define a `WASI_ROOT` env var in a build script to be able to
parse witx files.
With all that in place `wasi-common` becomes the source of truth for the
witx files we're parsing, and crates like `wasmtime-wasi` use
build-scripts shenanigans to read the same witx files. This should
hopefully get us so we're compatible with publishing and still only have
one submodule!
* rustfmt
* Bump Wasmtime to 0.14.0.
* Update the publish script for the wiggle crate wiggle.
* More fixes.
* Fix lightbeam depenency version.
* cargo update
* Cargo update wasi-tests too.
And add cargo update to the version-bump scripts.
* Shuffle around the wiggle crates
This commit reorganizes the wiggle crates slightly by performing the
following transforms:
* The `crates/wiggle` crate, previously named `wiggle`, was moved to
`crates/wiggle/crates/macro` and is renamed to `wiggle-macro`.
* The `crates/wiggle/crates/runtime` crate, previously named
`wiggle-runtime`, was moved to `crates/wiggle` and is renamed to
`wiggle`.
* The new `wiggle` crate depends on `wiggle-macro` and reexports the macro.
The goal here is that consumers only deal with the `wiggle` crate
itself. No more crates depend on `wiggle-runtime` and all dependencies
are entirely on just the `wiggle` crate.
* Remove the `crates/wiggle/crates` directory
Move everything into `crates/wiggle` directly, like `wasi-common`
* Add wiggle-macro to test-all script
* Fixup a test
