Looks like it's been awhile since our last update. I've updated the
dependency here and additionally vetted the various dependency upgrades.
I notably did not vet `zstd-sys` since that would require vetting all of
zstd's C implementation itself which I am not, nor do I suspect many of
are, equipped to do. In lieu of that I've updated the exemption of
`zstd-sys` to the newer version.
Closes#7869
* Update and add lots of docs, mostly for components
When I originally implemented the embedding API for the component model
I left a lot of `// TODO: say more here` style comments assuming I'd
come back around before stabilization. While I didn't quite make it in
time for Wasmtime 17 this is my attempt to improve things for the
future. This should add substantive documentation for all component-model
related things and flesh out some more details here and there. Nowhere
near comprehensive but, hey, Rome wasn't built in a day either.

* mpk: enable MPK if available in CI
After discussing several options for testing MPK in CI, this stopgap
measure at least provides some coverage. Other options include
maintaining a separate MPK-enabled CI runner (configuration is not
transparent, hard to maintain) or running the MPK-enabled tests in a
system-mode QEMU VM (tricky to get right, also hard to maintain). For
now, those of us at the Cranelift meeting agreed this at least gets some
CI testing for the MPK bits, which shouldn't be changing too often.
Since not all GitHub runners have MPK available, we only set the
`WASMTIME_TEST_FORCE_MPK` environment variable when it is. This change
also emits a warning to the GitHub logs in either case for easier
troubleshooting (e.g., to attempt to provide context if MPK logic breaks
and is only found in a later CI run).
prtest:full
* review: create a separate matrix entry
As requested by @alexcrichton, this change limits the MPK testing (and
the associated warnings) to a new matrix target: `Test Linux x86_64 with
MPK`.
* Fix handling of `Tunables` on cross-compiles
This commit fixes how Wasmtime handles `Tunables` when targetting
non-host platforms (or namely platforms with different pointer widths).
Previously the host's `Tunables` would always be used instead of the
target's tunables which meant that modules couldn't be loaded on the
other platform due to the host having differing tunables by default.
This commit updates tunables in `wasmtime::Config` to all be optional
and loading the actual `Tunables` is deferred until the target is known
during `Engine`-creation time.
* Fix warning
Using an epoch of `1` and setting its duration to the full timeout
configured does not work for `wasmtime serve`, as the epoch is counted
globally per engine. This commit switches to dividing the timeout by 10,
and expiring an instance after 11 epochs have been observed, giving a
maximum overshoot of 10%.

Like the rest of the `windows-*` crates published by Kenny Kerr, this
change also adds the `windows` crate itself to the trusted list. This is
necessary for use in #7807.
Simplify the implementation of the serve command by removing the
explicit Service trait impl, and using `service_fn` instead.

This commit updates the `wasmtime` crate itself to have the
`component-model` feature enabled by default. This was also done for the
CLI but only for clarity because the `component-model` feature was
already eanbled by default transitively through the `serve` feature.
Don't force-enable the `wasmtime-wast` crate if the `component-model`
feature is active, only activate component model support if
`wasmtime-wast` is otherwise activated.
* Shuffle some items around in `wasmtime`
This is a follow-up to #7766 with some more changes and reorganization.
These are some small items here and there which shouldn't have any
actual impact on functionality but are intended to reorganize a bit.
Changes here include:
* Move component artifact definitions to `wasmtime-environ` as core
module ones already live there.
* Rename the module with module artifacts from `instantiate` to
`module_artifacts`.
* Make `wasmtime-jit-icache-coherence` an optional dependency as only
the `runtime` feature requires it.
* Reorganize serialized metadata for wasmtime ELF files to consolidate
everything back into `wasmtime::engine::serialization`. This is to
prevent the definition of the serialization format being spread across
a few files.
* Touching up the `serialization` module to compile in all builds of the
`wasmtime` crate.
* fix docs typo

Currently translation of Wasm code uses the `FUNCREF_MASK` constant
which has type `usize` but this type is not always appropriate in
cross-compiled situations. This commit fixes the usage of `FUNCREF_MASK`
by using the platform-independent value (a negative value) along with
some extra asserts and an explantation of how to update if necessary.
Purely mechanical, no functional changes.
This is to help differentiate between value types (i32, i64, reference types,
etc...) and defined types (function signatures, struct definitions, array
definitions).
* Add `runtime` feature to `wasmtime` crate
This feature can be disabled to build `wasmtime` only for compilation.
This can be useful when cross-compiling, especially on a target that
can't run wasmtime itself (e.g. `wasm32`).
* prtest:full
* don't round pages without runtime feature
* fix async assertions
* move profiling into runtime
* enable runtime for wasmtime-wasi
* enable runtime for c-api
* fix build_artifacts in non-cache case
* fix miri extensions

* enable runtime for explorer
* support cranelift all-arch on wasm32
* add doc links for `WeakEngine`
* simplify lib runtime cfgs
* move limits and resources to runtime
* move stack to runtime
* move coredump and debug to runtime
* add runtime to coredump and async features
* add wasm32 build job
* combine engine modules
* single compile mod
* remove allow for macro paths
* add comments
* wasmtime: Rename `SignatureFooBar` to `TypeFooBar`
No functional changes, just the following mechanical renames:
* `VMSharedSignatureIndex` to `VMSharedTypeIndex`
* `SignatureIndex` to `TypeIndex`
* `SignatureRegistry` to `TypeRegistry`
* and more
This is intended to start paving the way for Wasm GC support, where there are
more than just function signatures in a Wasm module's type section, and we are
going to need to register non-function-signature types in the registry as well,
for things like casting between reference types and passing reference types
across Wasm modules.

* Break more data dependencies in float-related instructions
This commit takes a stab at #7816 without diving a whole lot into it. I
noticed that the loop started with `vcvtss2sd` which is along the same
lines as previous false dependencies found earlier in PRs such as #7098.
I had forgotten these instructions at the time and meant to go back and
touch them up and #7731 has provided sufficient motivation to do so!
Locally this takes that test case from 1.6s to 0.4s for me.
* Fix inst emit tests
* Update winch codegen
* Enable all winch tests on windows
prtest:mingw-x64
* Plumb through x64 unwind info creation
* Add the frame regs unwind info
* Emit UnwindInfo::SaveReg instructions
* Review feedback
* Comment the offset_downward_to_clobbers value
* Enable the component model by default
This commit enables the component model by default in the embedding API
and the CLI. This means that an opt-in of `-W component-model` is no
longer required and additionally `.wasm_component_model(true)` is no
longer required. Note that this won't impact existing embeddings since
the component model feature doesn't do much less `wasmtime::component`
is used, and if that's being used this is probably good news for you.
* Fix non-component model build
* WASI: copy in the version 0.2.0 wits
* wasmtime's wits: use versions 0.2.0 of wasi packages
* bindgens and other fixed version strings: change 0.2.0-rc-etc to 0.2.0
Previously temporary streams created as part of the preview1 adapter in
the wasmtime-wasi crate were left open which meant that they continued
to occupy space in the resource table and the underlying file
accidentally wasn't ever actually closed.
cc #7813
* update Wasmi fuzzing oracle to version 0.31.0
This allows us to enable the bulk-memory, reference-types and tail-call Wasm proposals for the Wasmi fuzzing oracle.
* apply rustfmt
* be more explicit about supported Wasm features
* align Wasmi config to input config
I am not sure if this is how it is intended to be used. Please review and provide feedback.
* remove duplicate threads_enabled
* remove min and max tables
We can do this since Wasmi supports reference-types Wasm proposal.
* add comment about config mutation
* use Wasmi v0.31.1
* be more explicit about supported Wasm features
* add comment about config mutation
* update wasmi_arena to v0.4.1
* preview 1 test-programs: fdflags_sync always unsupported
we never pursued making the fdflags_sync supported on any platform. rather than carry around this baggage, delete the configuration variable and make the single test that considered it always assert that fdflags_sync is not supported.
* fix warning
* Update to the latest wasi-io and wasi-sockets.
The only changes here are documentation changes in the Wit files. This
is just updating things so that it's easier to see what's up to date.
* Update wasi-http's copy of wasi-sockets too.
* Remove `+ Sync` constraints from preview2 implementation
* Only use mutable references in WasiView to guarantee unique access to Preview2 resources. Removed the _mut suffixes to align with WasiHttpView.
* Always use Descriptor::Directory for directories, regardless of whether they were preopened or opened using open_at. This fixes build errors regarding overlapping mutable lifetimes introduced in the previous commit.
* Remove some more `+ Sync`s
* Remove one more
* typo
* Fix build errors on Rust <= 1.73. Code already compiled fine on >= 1.74
