This updates to rustix 0.35.6, and updates wasi-common to use cap-std 0.25 and
windows-sys (instead of winapi).
Changes include:
- Better error code mappings on Windows.
- Fixes undefined references to `utimensat` on Darwin.
- Fixes undefined references to `preadv64` and `pwritev64` on Android.
- Updates to io-lifetimes 0.7, which matches the io_safety API in Rust.
- y2038 bug fixes for 32-bit platforms
* Update wasm-tools crates
This commit updates the wasm-tools family of crates as used in Wasmtime.
Notably this brings in the update which removes module linking support
as well as a number of internal refactorings around names and such
within wasmparser itself. This updates all of the wasm translation
support which binds to wasmparser as appropriate.
Other crates all had API-compatible changes for at least what Wasmtime
used so no further changes were necessary beyond updating version
requirements.
* Update a test expectation
* 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
Other than doc updates, this just contains bytecodealliance/cap-std#235,
a fix for compilation errors on Rust nightly that look like this:
```
error[E0308]: mismatched types

22 | let (old_dir, old_basename) = open_parent(old_start, &old_path)?;

```
Following up on #3696, use the new is-terminal crate to test for a tty
rather than having platform-specific logic in Wasmtime. The is-terminal
crate has a platform-independent API which takes a handle.
This also updates the tree to cap-std 0.24 etc., to avoid depending on
multiple versions of io-lifetimes at once, as enforced by the cargo deny
check.
* Update to cap-std 0.22.0.
The main change relevant to Wasmtime here is that this includes the
rustix fix for compilation errors on Rust nightly with the `asm!` macro.
* Add itoa to deny.toml.
* Update the doc and fuzz builds to the latest Rust nightly.
* Update to libc 0.2.112 to pick up the `POLLRDHUP` fix.
* Update to cargo-fuzz 0.11, for compatibility with Rust nightly.
This appears to be the fix for rust-fuzz/cargo-fuzz#277.
This pulls in a fix for Android, where Android's seccomp policy on older
versions is to make `openat2` irrecoverably crash the process, so we have
to do a version check up front rather than relying on `ENOSYS` to
determine if `openat2` is supported.
And it pulls in the fix for the link errors when multiple versions of
rsix/rustix are linked in.
And it has updates for two crate renamings: rsix has been renamed to
rustix, and unsafe-io has been renamed to io-extras.
* Use rsix to make system calls in Wasmtime.
`rsix` is a system call wrapper crate that we use in `wasi-common`,
which can provide the following advantages in the rest of Wasmtime:
- It eliminates some `unsafe` blocks in Wasmtime's code. There's
still an `unsafe` block in the library, but this way, the `unsafe`
is factored out and clearly scoped.
- And, it makes error handling more consistent, factoring out code for
checking return values and `io::Error::last_os_error()`, and code that
does `errno::set_errno(0)`.
This doesn't cover *all* system calls; `rsix` doesn't implement
signal-handling APIs, and this doesn't cover calls made through `std` or
crates like `userfaultfd`, `rand`, and `region`.
- Fixes for compiling on OpenBSD
- io-lifetimes 0.3.0 has an option (io_lifetimes_use_std, which is off
by default) for testing the `io_safety` feature in Rust nightly.
* Port wasi-common to io-lifetimes.
This ports wasi-common from unsafe-io to io-lifetimes.
Ambient authority is now indicated via calls to `ambient_authority()`
from the ambient-authority crate, rather than using `unsafe` blocks.
The `GetSetFdFlags::set_fd_flags` function is now split into two phases,
to simplify lifetimes in implementations which need to close and re-open
the underlying file.
* Use posish for errno values instead of libc.
This eliminates one of the few remaining direct libc dependencies.
* Port to posish::io::poll.
Use posish::io::poll instead of calling libc directly. This factors out
more code from Wasmtime, and eliminates the need to manipulate raw file
descriptors directly.
And, this eliminates the last remaining direct dependency on libc in
wasi-common.
* Port wasi-c-api to io-lifetimes.
* Update to posish 0.16.0.
* Embeded NULs in filenames now get `EINVAL` instead of `EILSEQ`.
* Accept either `EILSEQ` or `EINVAL` for embedded NULs.
* Bump the nightly toolchain to 2021-07-12.
This fixes build errors on the semver crate, which as of this writing
builds with latest nightly and stable but not 2021-04-11, the old pinned
version.
* Have cap-std-sync re-export ambient_authority so that users get the same version.
This bumps target-lexicon and adds support for the AppleAarch64 calling
convention. Specifically for WebAssembly support, we only have to worry
about the new stack slots convention. Stack slots don't need to be at
least 8-bytes, they can be as small as the data type's size. For
instance, if we need stack slots for (i32, i32), they can be located at
offsets (+0, +4). Note that they still need to be properly aligned on
the data type they're containing, though, so if we need stack slots for
(i32, i64), we can't start the i64 slot at the +4 offset (it must start
at the +8 offset).
Added one test that was failing on the Mac M1, as well as other tests
stressing different yet similar situations.
* Update wasm-tools crates
* Update Wasm SIMD spec tests
* Invert 'experimental_x64_should_panic' logic
By doing this, it is easier to see which spec tests currently panic. The new tests correspond to recently-added instructions.
* Fix: ignore new spec tests for all backends
