This commit updates the minimum Rust version supported by Wasmtime to
1.74.0 which is two behind the current stable 1.76. At the same time
this additionally updates nightly in CI to stay up-to-date there.
* update capstone dependency to 0.12.0
this is only used for benchmarking, so the cargo vet is just an exemption which I updated to the latest version.
* winch filetests: fix capstone changes
* Add a "custom" platform configuration for Wasmtime
This commit leverages adds a new "platform" to Wasmtime to be supported
in the `crates/runtime/src/sys` folder. This joins preexisting platforms
such as Unix and Windows. The goal of this platform is to be an opt-in
way to build Wasmtime for targets that don't have a predefined way to
run.
The new "custom" platform requires `--cfg wasmtime_custom_platform` to
be passed to the Rust compiler, for example by using `RUSTFLAGS`. This
new platform bottoms out in a C API that is intended to be small and
Linux-like. The C API is effectively the interface to virtual memory
that Wasmtime requires. This C API is also available as a header file at
`examples/min-platform/embedding/wasmtime-platform.h` (generated by
`cbindgen`).
The main purpose of this is to make it easier to experiment with porting
Wasmtime to new platforms. By decoupling a platform implementation from
Wasmtime itself it should be possible to run these experiments
out-of-tree. An example of this I've been working on is getting
Wasmtime running on bare-metal with a custom kernel. This support
enables defining the platform interface of the custom kernel's syscalls
outside of Wasmtime.
* Exclude wasmtime-platform.h from formatting
* Include build-wasmtime-target-wasm32 in final job
* Don't force any single toolchain
* Add notes to no_std docs
* Add rust-src to CI
* Review comments
* Change APIs to be fallible
* Only compile the min-platform example on Linux
* Fix compile of min-platform example
* Fix another compile error in the example
First of all, it is just a nice separation of concerns.
Second of all, as I design the GC rooting APIs for Wasmtime's upcoming Wasm GC
support, I want this same thing and I'd rather not open code it multiple times.
* Enable compiling the Wasmtime CLI to Wasm
While not the most useful thing to do in the world it's kind of neat to
play around with. This builds on the previous work to exclude the
runtime from the `wasmtime` crate so it's now possible to compile the
Wasmtime CLI's `compile` command, and only the `compile` command, to
wasm itself. This means you can run Wasmtime in Wasmtime!
* Fix warning on wasm
* Fix some feature combos
* Remove the `WASI` submodule
Historically the `WASI` submodule in this repository was used to pull
the sources of the `*.witx` files for preview1. This has never been used
by the `wasmtime-wasi` crate (which has its own copy in the
`crates/wasi/witx` folder) and was only ever used by `wasi-common`. This
submodule also served as a location for the `witx` crate itself.
Neither of these are really needed any more as the `*.witx` files are
unlikely to ever really change again. This commit removes the submodule
entirely, as well as the `path` dependency on `witx`, and copies the
`*.witx` files in the same manner as the `wasmtime-wasi` crate.
* Updated vet entries for witx
* Remove witx special cases in publish script
* Change how the wasi-common package is built

not a very modular design, but at this point wasi-common and
wasi-threads are forever wed
* fix wasmtime's docs
* re-introduce wasmtime-wasi's exports of wasi-common definitions behind deprecated
* factor out determining i32 process exit code
and remove libc dep because rustix provides the same constant

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.
* Move `jit` crate to `environ`
Move the platform agnostic parts of the crate `wasmtime-jit` to
`wasmtime-environ`. This is the first part of the refactoring discussed
here: https://github.com/bytecodealliance/wasmtime/issues/7652 and a
follow up will move the remaining parts of `wasmtime-jit` so that the
crate can be deleted.
* Move `jit` crate to `wasmtime`
Move the remaining parts of `wasmtime-jit` to the `wasmtime` crate and
remove `wasmtime-jit`. This is part of the refactoring discussed in
https://github.com/bytecodealliance/wasmtime/issues/7652.

* Gate more functionality behind `debug-builtins`
This commit extends the gating behavior of the preexisting
`debug-builtins` Cargo feature to cover more GDB-related functionality
associated with debugging. This can additionally slim down the set of
exposed symbols from Wasmtime over the default with them included.
* Move timing in Cranelift behind a Cargo feature
This commit adds a `timing` feature to the `cranelift-codegen` crate
which is enabled by default. This feature gates the timing functionality
in Cranelift to enable turning it off if desired. The goal of this
commit is to remove a system dependency on `Instant` for possibly
esoteric environments.
* Consolidate platform-specific definitions in Wasmtime
Prior to this commit Wasmtime did not not have a style or system for
containing platform-specific logic in files. The goal of this commit is
to consolidate all platform-specific functionality into one location to
make it easier to port Wasmtime to new systems. This commit creates a
`sys` module within the `wasmtime-runtime` crate which conditionally
defines all of the platform support that Wasmtime requires, namely
things related to virtual memory management and trap handling. Many of
the previous `unix.rs` files interspersed throughout the tree are now
all located in a single `unix` directory. This additionally helps split
out `miri`-specific functionality by pretending `miri` is its own
platform.
This change additionally goes through `#[cfg]` directives throughout
`wasmtime-runtime`, `wasmtime-jit`, and `wasmtime` itself to place all
of this target-specific functionality within this `sys` directory. The
end state is that there are two new top-level modules in the
`wasmtime-runtime` crate:
* `arch` - this conditionally defines architecture-specific logic such
as the state used by backtraces, libcalls, etc.
* `sys` - this conditionally defines OS or platform-specific logic such
as virtual memory management.
One secondary goal of this commit is to enable the ability to easily
add new platforms to Wasmtime, even if it's in a fork of Wasmtime.
Previously patches might have to touch a good number of locations where
now they'd ideally only have to touch `sys/mod.rs` to declare a new
platform and `sys/$platform/*.rs` to define all the functionality.

* mpk: allow checking for MPK without a config instance
It is inconvenient to have to construct a `PoolingAllocationConfig` in
order to check if memory protection keys are available. This removes
the unused `&self` restriction.
* mpk: improve logging of calculated slab layout
When double-checking the slab layout calculations it is quite convenient
to see the total slab size. This helps in correlating with mapped
regions.
* mpk: add an example testing the memory limits
This adds an example that can be run with `cargo run --example mpk`. Not
only does the example demonstrate how to build a pool-allocated engine
that uses MPK, it performs an exponential search to find the maximum
number of slots the system can support, with and without MPK.

* vet: audit `bytesize`
* fix: provide `main` for non-Linux systems
* fix: move `cfg` to avoid unused code
This commit updates to the latest wasm-tools and `wit-bindgen` to bring
the family of crates forward. This update notably includes Nick's work
on packed indices in the `wasmparser` crate for validation for the
upcoming implementation of GC types. This meant that translation from
`wasmparser` types to Wasmtime types now may work with a "type id"
instead of just a type index which required plumbing not only Wasmtime's
own type information but additionally `wasmparser`'s type information
throughout translation.
This required a fair bit of refactoring to get this working but no
change in functionality is intended, only a different way of doing
everything prior.
* Configure Rust lints at the workspace level
This commit adds necessary configuration knobs to have lints configured
at the workspace level in Wasmtime rather than the crate level. This
uses a feature of Cargo first released with 1.74.0 (last week) of the
`[workspace.lints]` table. This should help create a more consistent set
of lints applied across all crates in our workspace in addition to
possibly running select clippy lints on CI as well.
* Move `unused_extern_crates` to the workspace level
This commit configures a `deny` lint level for the
`unused_extern_crates` lint to the workspace level rather than the
previous configuration at the individual crate level.
* Move `trivial_numeric_casts` to workspace level
* Change workspace lint levels to `warn`
CI will ensure that these don't get checked into the codebase and
otherwise provide fewer speed bumps for in-process development.
* Move `unstable_features` lint to workspace level
* Move `unused_import_braces` lint to workspace level
* Start running Clippy on CI
This commit configures our CI to run `cargo clippy --workspace` for all
merged PRs. Historically this hasn't been all the feasible due to the
amount of configuration required to control the number of warnings on
CI, but with Cargo's new `[lint]` table it's possible to have a
one-liner to silence all lints from Clippy by default. This commit by
default sets the `all` lint in Clippy to `allow` to by-default disable
warnings from Clippy. The goal of this PR is to enable selective access
to Clippy lints for Wasmtime on CI.
* Selectively enable `clippy::cast_sign_loss`
This would have fixed#7558 so try to head off future issues with that
by warning against this situation in a few crates. This lint is still
quite noisy though for Cranelift for example so it's not worthwhile at
this time to enable it for the whole workspace.
* Fix CI error
prtest:full
Pull in bytecodealliance/wasm-tools#1277 to switch the defaults for some
WIT behaviors:
* Semicolons are now required by default in WIT files
* Wasm-encoded WIT packages now use the "new" format by default.
WIT files without semicolons can still be parsed with
`WIT_REQUIRE_SEMICOLONS=0`. The "old" format for wasm-encoded WIT
packages can be emitted via `WIT_COMPONENT_ENCODING_V2=0`. Note that for
wasm-encoded WIT packages both the old and the new format can be decoded
irregardless of env vars.
* Enable `wasmtime/wat` when the `wat` feature is enabled on the CLI
* Additionally always enable the `wasmtime/wat` feature for the
`wasmtime-wast` crate since the text format is used by some tests.
Closes#7460
* Update wasm-tools crates
This commit updates the wasm-tools family of crate for a number of
notable updates:
* bytecodealliance/wasm-tools#1257 - wasmparser's ID-based
infrastructure has been refactored to have more precise types for each
ID rather than one all-purpose `TypeId`.
* bytecodealliance/wasm-tools#1262 - the implementation of
"implementation imports" for the component model which both updates
the binary format in addition to adding more syntactic forms of
imports.
* bytecodealliance/wasm-tools#1260 - a new encoding scheme for component
information for `wit-component` in objects (not used by Wasmtime but
used by bindings generators).
Translation for components needed to be updated to account for the first
change, but otherwise this was a straightforward update.
* Remove a TODO
* Add compatibility shims for Wasmtime 13 CLI
This commit introduces a compatibility shim for the Wasmtime 13 CLI and
prior. The goal of this commit is to address concerns raised in #7336
and other locations as well. While the new CLI cannot be un-shipped at
this point this PR attempts to ameliorate the situation somewhat through
a few avenues:
* A complete copy of the old CLI parser is now included in `wasmtime` by
default.
* The `WASMTIME_NEW_CLI=0` environment variable can force usage of the
old CLI parser for the `run` and `compile` commands.
* The `WASMTIME_NEW_CLI=1` environment variable can force usage of the
new CLI parser.
* Otherwise both the old and the new CLI parser are executed. Depending
on the result one is selected to be executed, possibly with a warning
printed.
* If both CLI parsers succeed but produce the same result, then no
warning is emitted and execution continues as usual.
* If both CLI parsers succeed but produce different results then a
warning is emitted indicating this. The warning points to #7384 which
has further examples of how to squash the warning. The warning also
mentions the above env var to turn the warning off. In this situation
the old semantics are used at this time instead of the new semantics.
It's intended that eventually this will change in the future.
* If the new CLI succeeds and the old CLI fails then the new semantics
are executed without warning.
* If the old CLI succeeds and the new CLI fails then a warning is issued
and the old semantics are used.
* If both the old and the new CLI fail to parse then the error message
for the new CLI is emitted.
Note that this doesn't add up to a perfect transition. The hope is that
most of the major cases of change at the very least have something
printed. My plan is to land this on `main` and then backport it to the
14.0.0 branch as a 14.0.3 release.

This is required to compile for a target which doesn't have a cranelift
backend. Before this change using any of the cranelift crates that
depend on cranelift-codegen would forcefully enable all default features
and thus host-arch. With this change only the std and unwind features
are still forcefully enabled as cranelift-codegen doesn't compile with
either disabled.
This commit introduces a wrapper crate which is now the new "real" C
API. The purpose of this change is to enable using LTO when building the
C API. Currently LTO is disabled because one of the crate types of the C
API is an "rlib" which means that it can't have LTO performed due to
rustc limitations. The solution here is to remove the "cdylib" and
"staticlib" crate types from the "wasmtime-c-api" crate, rename that
crate to "wasmtime-c-api-impl", and reintroduce 'wasmtime-c-api' as a
new crate which wraps the previous crate and reexports it.
This way LTO can be enabled when just building the artifacts and the use
case from #6765 is still satisfied by having a crate that can be linked
to from Rust. Locally this reduces the size of the C API artifact for me
by nearly 1M.
While not a large amount of binary size if the purpose of the
`--no-default-features` build is to showcase "minimal Wasmtime" then may
as well try to make `clap` as small as possible.
