* Document the `wasmtime::Instance` APIs
This documents oddities like the import list and export list and how to
match them all up. Addtionally this largely just expands all the docs
related to `Instance` to get filled out.
This also moves the `set_signal_handler` functions into
platform-specific modules in order to follow Rust idioms about how to
expose platform-specific information. Additionally the methods are
marked `unsafe` because I figure anything having to do with signal
handling is `unsafe` inherently. I don't actually know what these
functions do, so they're currently still undocumented.
* Fix build of python bindings
* Fix some rebase conflicts
* Don't require `Store` in `Instance` constructor
This can be inferred from the `Module` argument. Additionally add a
`store` accessor to an `Instance` in case it's needed to instantiate
another `Module`.
cc #708
* Update more constructors
* Fix a doctest
* Don't ignore store in `wasm_instance_new`
* Run rustfmt
* Remove `HostRef` from the `wasmtime` public API
This commit removes all remaining usages of `HostRef` in the public API
of the `wasmtime` crate. This involved a number of API decisions such
as:
* None of `Func`, `Global`, `Table`, or `Memory` are wrapped in `HostRef`
* All of `Func`, `Global`, `Table`, and `Memory` implement `Clone` now.
* Methods called `type` are renamed to `ty` to avoid typing `r#type`.
* Methods requiring mutability for external items now no longer require
mutability. The mutable reference here is sort of a lie anyway since
the internals are aliased by the underlying module anyway. This
affects:
* `Table::set`
* `Table::grow`
* `Memory::grow`
* `Instance::set_signal_handler`
* The `Val::FuncRef` type is now no longer automatically coerced to
`AnyRef`. This is technically a breaking change which is pretty bad,
but I'm hoping that we can live with this interim state while we sort
out the `AnyRef` story in general.
* The implementation of the C API was refactored and updated in a few
locations to account for these changes:
* Accessing the exports of an instance are now cached to ensure we
always hand out the same `HostRef` values.
* `wasm_*_t` for external values no longer have internal cache,
instead they all wrap `wasm_external_t` and have an unchecked
accessor for the underlying variant (since the type is proof that
it's there). This makes casting back and forth much more trivial.
This is all related to #708 and while there's still more work to be done
in terms of documentation, this is the major bulk of the rest of the
implementation work on #708 I believe.
* More API updates
* Run rustfmt
* Fix a doc test
* More test updates
This commit continues previous work and also #708 by removing the need
to use `HostRef<Module>` in the API of the `wasmtime` crate. The API
changes performed here are:
* The `Module` type is now itself internally reference counted.
* The `Module::store` function now returns the `Store` that was used to
create a `Module`
* Documentation for `Module` and its methods have been expanded.
* Remove the need for `HostRef<Module>`
This commit continues previous work and also #708 by removing the need
to use `HostRef<Module>` in the API of the `wasmtime` crate. The API
changes performed here are:
* The `Module` type is now itself internally reference counted.
* The `Module::store` function now returns the `Store` that was used to
create a `Module`
* Documentation for `Module` and its methods have been expanded.
* Fix compliation of test programs harness
* Fix the python extension
* Update `CodeMemory` to be `Send + Sync`
This commit updates the `CodeMemory` type in wasmtime to be both `Send`
and `Sync` by updating the implementation of `Mmap` to not store raw
pointers. This avoids the need for an `unsafe impl` and leaves the
unsafety as it is currently.
* Fix a typo
* Remove the need for `HostRef<Store>`
This commit goes through the public API of the `wasmtime` crate and
removes the need for `HostRef<Store>`, as discussed in #708. This commit
is accompanied with a few changes:
* The `Store` type now also implements `Default`, creating a new
`Engine` with default settings and returning that.
* The `Store` type now implements `Clone`, and is documented as being a
"cheap clone" aka being reference counted. As before there is no
supported way to create a deep clone of a `Store`.
* All APIs take/return `&Store` or `Store` instead of `HostRef<Store>`,
and `HostRef<T>` is left as purely a detail of the C API.
* The `global_exports` function is tagged as `#[doc(hidden)]` for now
while we await its removal.
* The `Store` type is not yet `Send` nor `Sync` due to the usage of
`global_exports`, but it is intended to become so eventually.
* Touch up comments on some examples
* Run rustfmt
Instead expose a number of boolean accessors which doesn't require users
to construct a foreign `Features` type and allows us to decouple the API
of the `wasmtime` crate from the underlying implementation detail.
This commit removes the need to use `HostRef<Engine>` in the Rust API.
Usage is retained in the C API in one location, but otherwise `Engine`
can always be used directly.
This is the first step of progress on #708 for the `Engine` type.
Changes here include:
* `Engine` is now `Clone`, and is documented as being cheap. It's not
intended that cloning an engine creates a deep copy.
* `Engine` is now both `Send` and `Sync`, and asserted to be so.
* Usage of `Engine` in APIs no longer requires or uses `HostRef`.
* Refactor the `types.rs` types and structures
A few changes applied along the way:
* Documentation added to most methods and types.
* Limits are now stored with the maximum as optional rather than a
sentinel u32 value for `None`.
* The `Name` type was removed in favor of just using a bare `String`.
* The `Extern` prefix in the varaints of `ExternType` has been removed
since it was redundant.
* Accessors of `ExternType` variants no longer panic, and unwrapping
versions were added with "unwrap" in the name.
* Fields and methods named `r#type` were renamed to `ty` to avoid
requiring a raw identifier to use them.
* Remove `fail-fast: false`
This was left around since the development of GitHub Actions for
wasmtime, but they're no longer needed!
* Fix compilation of the test-programs code
* Fix compilation of wasmtime-py package
* Run rustfmt
* Rename the `wasmtime_api` library to match the containing `wasmtime` crate
Commit d9ca508f80 renamed the
`wasmtime-api` crate to `wasmtime`, but left the name of the library it
contains as `wasmtime_api`.
It's fairly unusual for a crate to contain a library with a different
name, and it results in rather confusing error messages for a user; if
you list `wasmtime = "0.7"` in `Cargo.toml`, you can't `use
wasmtime::*`, you have to `use wasmtime_api::*;`.
Rename the `wasmtime_api` library to `wasmtime`.
* Stop renaming wasmtime to api on imports
Various users renamed the crate formerly known as wasmtime_api to api,
and then used api:: prefixes everywhere; change those all to wasmtime::
and drop the renaming.
This commit does two things: 1) it fixes `wasmtime_rust::wasmtime` proc macro by
adding the missing import to the `__rt` module, and fixing the scoping inside
the macro itself; and 2) it augments the `wasmtime_rust::wasmtime` proc macro with
custom error messages in case the implementor forgets the `self` argument in the
trait methods.
* Fix fuzz target compilation.
* Bump version to 0.7.0
* Temporarily disable fuzz tests
Temporarily disable fuzz tests until https://github.com/bytecodealliance/cranelift/issues/1216 is resolved.
* Fix publish-all.sh to not modify the witx crate.
* Remove the "publish = false" attribute from Lightbeam.
* Add a README.md for wasmtime-interface-types.
* Remove the "rust" category.
This fixes the following warning:
warning: the following are not valid category slugs and were ignored: rust. Please see https://crates.io/category_slugs for the list of all category slugs.
* Mark wasmtime-cli as "publish = false".
* Sort the publishing rules in topological order.
Also, publish nightly-only crates with cargo +nightly.
This commit is an attempt to reduce the number of crates necessary to
link to when using `wasmtime::Config` in "default mode" or with only one
or two tweaks. The change moves to a builder-style pattern for `Config`
to only require importing crates as necessary if you configure a
particular setting. This then also propagates that change to `Context`
as well by taking a `Config` instead of requiring that all arguments are
passed alone.
* General Cargo.toml cleanup.
- Remove travis-ci attributes.
- Remove "experimental" badges from actively-developed crates.
- Reflow some long lines.
- Use dependency features consistently.
- Add readme attributes
* Update WASI to the latest trunk.
This notably adds a .gitignore file for the WASI directory.
