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
* Add preliminary support for host-specific errors
* 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
* Move ManuallyDrop up one level from Descriptor to FdObject
* 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
* Use File::sync_data to impl fd_datasync
* Rewind file cursor after fd_p{read, write} on Windows
* Add fd_p{read, write} tests
* Handle errors instead of panicking in path_get
* Use File::set_len to impl fd_allocate
* 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).
