* Wasmtime 0.15.0 and Cranelift 0.62.0. (#1398)
* Bump more ad-hoc versions.
* Add build.rs to wasi-common's Cargo.toml.
* Update the env var name in more places.
* Remove a redundant echo.
* Bump Wasmtime to 0.14.0.
* Update the publish script for the wiggle crate wiggle.
* More fixes.
* Fix lightbeam depenency version.
* cargo update
* Cargo update wasi-tests too.
And add cargo update to the version-bump scripts.
* Add support for virtual files (eg, not backed by an OS file).
Virtual files are implemented through trait objects, with a default
implementation that tries to behave like on-disk files, but entirely
backed by in-memory structures.

* 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
This commit implements `fd_fdstat_set_flags` for Windows.
Additionally, it fixes a problem where `O_APPEND` was not working correctly
because `GENERIC_WRITE` was always being set; as a result, `FILE_WRITE_DATA`
could not be removed from the permission set to properly enable append-only
mode.
It also treats `O_TRUNC` with `O_APPEND` as an invalid argument error. This is
because Windows cannot support these two flags together. To support `O_TRUNC`,
the `GENERIC_WRITE` bit must be set for the file access flags. Setting this
bit will cause `FILE_WRITE_DATA` to be set, which will not properly treat the
file as append-only (it requires `FILE_APPEND_DATA` without `FILE_WRITE_DATA`).
* Fix path_open granting more rights than requested
* Add missing rights checks in: fd_fdstat_set_flags, fd_filestat_get, poll_oneoff
* Fix `open_scratch_directory` not requesting any rights.
* Properly request needed rights in various tests
* Add some extra trace-level logging
* Remove a no-op restriction of rights to the ones returned by
`determine_type_rights`. It was redundant, because `FdEntry:from`
internally also called `determine_type_rights` and only dropped some of them.
This commit updates _all_ WASI test programs to use the latest
version of the `wasi` crate (`v0.9.0`). While at it, it also
unifies asserting error conditions across all test programs.
* 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
* 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 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!`.
