* when executed twice in a row, need to manually reset the stream
by calling seekdir with __WASI_DIRCOOKIE_START, if __WASI_DIRCOOKIE_START
was specified
* fix mapping between d_type and __wasi_filetype_t
* include minor refactor - removes use of wasm32 module on the
host's side
* Move path_get outside of sys module
* Add implementation of readlinkat
* Clean up path_open; use OpenOptions as much as possible
* Enable close_preopen test
* Implement path_create_directory; fix path_open
* Refactor path concatenation onto a descriptor
* Implement path_remove_directory
* Implement path_unlink_file
* Rewrite path_open using specific access mask
* Fix error mapping when unlinking file
* Fix readlinkat to pass nofollow_errors testcase
* Clean up winerror to WASI conversion
* Spoof creating dangling symlinks on windows (hacky!)
* Add positive testcase for readlink
* Implement path_readlink (for nonzero buffers for now)
* Clean up
* Add Symlink struct immitating *nix symlink
* Fix path_readlink
* Augment interesting_paths testcase with trailing slashes example
* Encapsulate path_get return value as PathGet struct
* Remove dangling symlink emulation
* Extract dangling symlinks into its own testcase
This way, we can re-enable nofollow_errors testcase
on Windows also.
* Return __WASI_ENOTCAPABLE if user lacks perms to symlink
* 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
* 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
