* Rename the crate to wasi-misc-tests.
* Update to wasi 0.7.0.
This switches from using the libc wasi bindings to using the wasi
crate's bindings. This eliminates a git dependency on libc, updates
to the new-style bindings which use Result where possible, and treats
functions that operate on raw file descriptors as unsafe.
* Add various tests for trailing-slash behavior.
* Sync new testcases with latest upstream
* Fix path_filestat testcase
* Add smoke test for fd_advise
This test is a true smoke test as it only tests whether issuing
an advise call to the host's kernel doesn't yield an error. The
consequence of issuing such a syscall is not tested.

This commit adds a test case for `poll_oneoff` syscall. In particular,
it builds on the excellent test use case provided by @dunnock in their
repo [poll_oneoff_tests] (thanks!), and tests:
* simple timeout

* Add smoke test for STDOUT/ERR readwrite poll
* Add comment on stdin/out/err
* Add a test for `*at`-style functions returning `ENOTDIR` when `dirfd` is not a dir.
* Remove misc_testsuite submodule
* Add "publish=false" to Cargo.toml; remove LICENSE
* fix Linux `isatty` implementation
* defer `WasiCtxBuilder` errors to `build()`; don't change API yet
This changes the fields on the builder to types that let the various `.arg()`, `.env()`, etc methods
infallible, so we don't have to worry about handling any errors till we actually build. This reduces
line noise when using a builder in a downstream application.
Deferring the processing of the builder fields also has the advantage of eliminating the opening and
closing of `/dev/null` for the default stdio file descriptors unless they're actually used by the
resulting `WasiCtx`.
Unicode errors when inheriting arguments and environment variables no longer cause a panic, but
instead go through `OsString`. We return `ENOTCAPABLE` at the end if there are NULs, or if UTF-8
conversion fails on Windows.
This also changes the bounds on some of the methods from `AsRef<str>` to `AsRef<[u8]>`. This
shouldn't break any existing code, but allows more flexibility when providing arguments. Depending
on the outcome of https://github.com/WebAssembly/WASI/issues/8 we may eventually want to require
these bytes be UTF-8, so we might want to revisit this later.
Finally, this fixes a tiny bug that could arise if we had exactly the maximum number of file
descriptors when populating the preopens.
* make `WasiCtxBuilder` method types less restrictive
This is a separate commit, since it changes the interface that downstream clients have to use, and
therefore requires a different commit of `wasmtime` for testing. That `wasmtime` commit is currently
on my private fork, so this will need to be amended before merging.
Now that failures are deferred until `WasiCtxBuilder::build()`, we don't need to have `Result` types
on the other methods any longer.
Additionally, using `IntoIterator` rather than `Iterator` as the trait bound for these methods is
slightly more general, and saves the client some typing.
* enforce that arguments and environment variables are valid UTF-8
* remove now-unnecessary platform-specific OsString handling
* `ENOTCAPABLE` -> `EILSEQ` for failed arg/env string conversions
* fix up comment style
* Apply @acfoltzer's fix to isatty on Linux to BSD
* Implement clock_time_get on Windows.
Also update misc_testsuite to include latest clock_time_get test
changes.
* Try to somehow implement clock_res_get on Windows.
* Fix 55ms
* Cache the perf counter resolution
* Fix integration tests
* Bump crate versions.
* Update dependency version numbers too.
This is a follow-up to f96b6c9e72ae50fcddd488be47a2d4b5ac7b926b to
update the version numbers in the local dependencies too.
* Use generated type bindings.
Use the witx API descriptions to generate the bulk of the contents of
host.rs, wasi.rs, and wasi32.rs.
This also prunes out many of the miscellaneous libc definitions from
those files which aren't currently in use by wasi-common. If there's
anything removed that's still needed by someone, it's easy to add things
back in.
* Remove unneeded iovec conversion routines.
Since `wasmtime` now uses `wasi` and `wasi32` modules, we can now
safely remove the `wasm32` module. This commit also updates `wasmtime`
to the latest upstream.
* Reorganize host.rs and wasm32.rs.
Reorganize host.rs and wasm32.rs into host.rs, wasi.rs, and wasi32.rs.
Most of the contents of host.rs was not actually host-specific, as most
of the types are fixed-size types like u32 or i64. These types are now
in wasi.rs.
The few types which do have pointer or usize-sized values now remain,
in two versions: host.rs has versions which use actual raw pointers and
usize, and wasi32.rs has versions which use u32 to represent them.
* Fix compilation on BSD
* Fix compilation on Windows
* Fully encapsulate endianness in memory.rs.
This refactors memory.rs to fully encapsulte endianness concerns, so
that outside that file, all values are in host-endian order.
This adds a dependency on the `num` crate, though it's only used for
the `PrimInt` trait, for handling endianness in a generic way.
* Use pub(crate).
* Fix some Windows warnings.
* Implement clock_time_get on Windows.
Also update misc_testsuite to include latest clock_time_get test
changes.
* improve comments
* Remove a leftover import.

This commit syncs tests with latest wasmtime revision.
As such, it now utilises the `wasmtime-api` crate for
runtime setup.
Closes#126, #127, #128, #129.
* Put misc_testsuite behind a feature gate
This PR puts building and generating of misc_testsuite behind
a feature gate "misc_testsuite". This is mainly to allow projects
which pull `wasi-common` as a dependency not to have to have
`wasm32-wasi` target installed in order to build it as it currently
is.
* Update the CI
* Rename feature to wasm_tests
* Explain integration testing in the README
Changes:
* use [tempfile] crate for auto mgmt of temp dirs
* use concrete types in place of generics in `utils` module
[tempfile]: https://github.com/Stebalien/tempfile
Internal modules `memory` and `host` can indeed be internal hidden
behind public-private visibility as `wasmtime-wasi` has already
been updated not to use the said modules (see
CraneStation/wasmtime#298).
* Rewrite FdEntry reusing as much libstd as possible
* Use the new FdEntry, FdObject, Descriptor struct in *nix impl
* Adapt Windows impl
* Remove unnecessary check in fd_read
Check `host_nread == 0` caused premature FdEntry closure and removal
which ultimately was resulting in an attempt at "double closing" of
the same file descriptor at the end of the Wasm program:
...
fd_close(fd=4)
-> errno=WASI_ESUCCESS
fd_close(fd=4)
-> errno=WASI_EBADF
* Use libstd vectored IO
* Use std:🧵:yield_now to implement sched_yield
* Add logging to integration tests

* Operate on std::fs::File in path_get on *nix
* Add cross-platform RawString type encapsulating OsStrExt
* Fix Windows build
* Update Travis and README to Rust v1.36
* Remove unused winx::handle::close helper
* Refactor Descriptor into raw handles/fds
* Strip readlinkat in prep for path_get host-independent
* Strip openat in prep for path_get host-independent

* Make (c)iovec host fns unsafe
* Swap unwraps/expects for Results in fdentry_impl on nix
* Rewrite fd_pread/write and implement for Win
* Use File::sync_all to impl fd_sync

* Add test for fd_allocate
* Replace all panics with Results
* Document the point of RawString
* Add partial impl of determine_type_rights fn
* Add draft of fd_fdstat_get hostcall
* Add writev wrapper for writing IoVec in RawHandle
* Move IoVec and writev to separate helper crate
* Add Win error handling
Clean up closing and duplicating RawHandle
* Wrap Win file type result
* Add draft impl of fd_close and fd_read
* Refactor getting file access rights
* Remove winapi from the main Cargo.toml
* Add very rough draft of open_path (very incomplete)
* Clean up WinError with macro
* Ignore dir handle in openat if path absolute
* Decode oflags and advance open_path hostcall
* Clean up AccessRight and FlagsAndAttributes flags
* Implement path_get (without symlink expansion yet!)
* Add ShareMode and fix path_get for nested paths
* Add some error mappings between Win and WASI
* Clean up fdflags conversions
* Fix sharing violation when calling openat at '.'
* Apply Alex's fix of using ManuallyDrop instead forget
* Clean up
* Explicitly specify workspace to avoid comp errors at tests
Now, test binaries are bundled with the repo, and
just like in CraneStation/wasmtime, the test cases
are generated automatically using build.rs. So all
it takes is to drop a new test binary in the
testsuite dir to get the test case for it generated
(with some caveats to do with handling preopens).
