* Move `wasi` to `wasi_old` in wasi-tests
Leave space for the new `wasi` crate but allow us to incrementally
update tests.
* Update the big_random_buf test
* Update clock_time_get test
* Update close_preopen test
* Review comments
* Update to latest Wasmtime API
* 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
* Deny warnings in the CI by default
This commit passes `-D warnings` flag to `rustc` in the Test stage
of the CI in order to deny warnings on _all_ tested platforms.
* Fix warnings
* Fix warnings
* Support fd_fdstat_get on stdin/stdout/stderr.
Add a routine for obtaining an `OsFile` containing a file descriptor for
stdin/stdout/stderr so that we can do fd_fdstat_get on them.
* Add a testcase for fd_fdstat_get etc. on stdin etc.
* Don't dup file descriptors in fd_renumber.
* Fix compilation on macOS
* Rename OsFile to OsHandle
This commits renames `OsFile` to `OsHandle` which seems to make
more sense semantically as it is permitted to hold a valid OS handle
to OS entities other than simply file/dir (e.g., socket, stream, etc.).
As such, this commit also renames methods on `Descriptor` struct
from `as_actual_file` to `as_file` as this in reality does pertain
ops on FS entities such as files/dirs, and `as_file` to `as_os_handle`
as in this case it can be anything, from file, through a socket, to
a stream.
* Fix compilation on Linux
* Introduce `OsHandleRef` for borrowing OS resources.
To prevent a `ManuallyDrop<OsHandleRef>` from outliving the resource it
holds on to, create an `OsHandleRef` class parameterized on the lifetime
of the `Descriptor`.
* Fix scoping to pub-priv and backport to snapshot_0
This commit fully implements `__wasi_fd_fdstat_get` on Windows so that
the descriptor flags can be determined.
It does this by calling into `NtQueryInformationFile` (safe to call from
user mode) to get the open mode and access of the underlying OS handle.
`NtQueryInformationFile` isn't included in the `winapi` crate, so it is
manually being linked against.
This commit also fixes several bugs on Windows:
* Ignore `__WASI_FDFLAG_NONBLOCK` by not setting `FILE_FLAG_OVERLAPPED`
on file handles (the POSIX behavior for `O_NONBLOCK` on files).
* Use `FILE_FLAG_WRITE_THROUGH` for the `__WASI_FDFLAG_?SYNC` flags.
* `__WASI_FDFLAG_APPEND` should disallow `FILE_WRITE_DATA` access to
force append-only on write operations.
* Use `GENERIC_READ` and `GENERIC_WRITE` access flags. The
latter is required when opening a file for truncation.
* Fix feature-gating of test-programs
This commit fixes bugs in enabling feature-gating of `test-programs`
which was introduced in #600. It turns out, #600 accidentally
disabled `test-programs` from ever running, and this commit fixes
that.
* Fix the CI
* 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.
* Add support for wasi_snapshot_preview1.
This adds support for the new ABI, while preserving compatibility
support for the old ABI.
* Fix compilation on platforms where nlink_t isn't 64-bit.
* rustfmt
* Fix Windows build errors.
* Remove unneded prefix argument from `instantiate_wasi`.
This was an artifact of an earlier backwards-compatibility mechanism
which is no longer needed.
* Remove unneeded prefix arg from remaning uses
* Add test for dangling file/dir handles
This commit adds a test for dangling file/dir handles. The logic is
quite simple: we first create a resource (file or dir), get a WASI file
descriptor to it, remove the resource without closing the FD, and then
try to re-create it.
* Disable on Windows for now
* 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 fixes rights check for `fd_pread` and `fd_pwrite` to be
conformant with the WASI spec. In the spec, it is clearly stated that
the right to invoke `__wasi_fd_pread()` requires a combination of
`__WASI_RIGHT_FD_READ` with `__WASI_RIGHT_FD_SEEK`, and similarly for
`__wasi_fd_pwrite()` the combination is `__WASI_RIGHT_FD_WRITE` with
`__WASI_RIGHT_FD_SEEK`. Relevant link to the spec: [__wasi_rights_t].

* Reorganize wasi-misc-tests.
Move wasi-misc-tests out of wasi-common, to break a dependency cycle;
previously, wasmtime-* depended on wasi-common, but wasi-common
dev-dependended on wasmtime-*.
Now, wasi-common no longer dev-depends on wasmtime-*; instead, the
tests are in their own crate which depends on wasi-common and on
wasmtime-*.
Also, rename wasi-misc-tests to wasi-tests for simplicity.
This also removes the "wasm_tests" feature; it's replaced by the
"test-programs" feature.
* Update the CI script to use the new feature name.
* Update the CI script to use the new feature name in one more place.
* Change a `write!` to a `writeln!`.
