* Implement fd_filestat_get for all platforms
* Remove an old comment
* Remove panics from the syscall wrappers
* Return WASI error type
* Reuse Metadata if possible to save syscalls.
* Refactor the change for two separate fd_filestat_get_impl
* Refactor error handling
* 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

* 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).
Linux's open returns ENOTDIR when used with O_DIRECTORY|O_NOFOLLOW and
the path is a symlink. Update the code to expect this.
FreeBSD's open returns EMLINK instead of ELOOP when using O_NOFOLLOW on
symlink. Update the code to expect this.
WASI currently lacks the ability to specify the full UNIX access control
information when creating files and directories, so for now just avoid
creating executable files and rely on the umask.
If a path_open call is requesting __WASI_RIGHT_FD_FILESTAT_SET_SIZE,
interpret that as a request for write privleges. If it is requesting
O_TRUNC, require __WASI_RIGHT_PATH_FILESTAT_SET_SIZE, since this is
a path operation rather than a FD operation.
