* Initial checkin.
* Update to rust-lang libc.
* Add a .gitignore file.
* Factor out functions for cleaning up files and directories.
* Fix a typo in a comment.
* Print a "Success!" message if all tests passed.
* Factor out code for creating directories.
* Add wrappers around WASI functions.
These wrappers handle converting from &str to pointer+length and handle
unsafe.
* More refactoring.
* Refactor a fd_close helper.
* Move utility functions into a separate file.
* cargo update
* Add a basic test for random_get.
* Test that directories aren't resizable.
* Test clearing __WASI_RIGHT_PATH_FILESTAT_SET_SIZE.
Ensure that clearing __WASI_RIGHT_PATH_FILESTAT_SET_SIZE succeeds before
testing file truncation.
* cargo update
* Modularise tests for easier use with wasi-common crate
* Add a Code of Conduct and CONTRIBUTING.md.
* Fix typo
* Add testcase for fd_allocate
* Add positive test for fd_renumber
* Assert bufused in readlink_no_buffer testcase
* Add positive readlink testcase
* Add testcase for fd_seek and fd_tell
* Add fd_p{read, write} test
* Add README
* Add cases with trailing slashes to interesting_paths
* Split nofollow_errors testcase into two
* nofollow_errors now operators on symlinks to existing resources
* dangling_symlink covers danling symlinks tests
* Factor out a `create_file` helper function.
* Switch from the error crate to `std::io::Error::last_os_error()`.
* Use `create_file` in the readlink test too.
* Add a test for fd_filestat_set_*
* Minor refactoring
Add missing cleanup_file calls to file_pread_pwrite and
file_seek_tell.
* Add testcase for unbuffered fd_write; fixes #11
* Add testcase for path_rename
* Use the wasi crate.
Switch from depending on libc to depending on the new wasi crate to provide
the low-level WASI interfaces.
See also https://github.com/rust-lang/libc/pull/1461.
* Add a test for path_filestat_*
* Add a test for fd_readdir
* Use expect instead of unwrap
* Add a check for ino.
* Fix the build
* Don't assume a specific order of dirents
* Better test
* Test cookie value
* Fix file types
* Fix the test
* Fix the test
* Fix the test
* Cleanup
* Minor formatting tidying in README.md.
* Fix miscellaneous clippy warnings.
* 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.
* Check if CLOCK_MONOTONIC is actually monotonic
* Refactor the inequality assertions for more debuggable errors.
* Bump libc from 0.2.62 to 0.2.65
Bumps [libc](https://github.com/rust-lang/libc) from 0.2.62 to 0.2.65.

This commit enables Github Actions and adds corresponding configuration in rust.yml file.
* Update rust.yml

* Add test case for `poll_oneoff` syscall (#38)
* Add test case for `poll_oneoff` syscall
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
* stdin read with timeout
* fd read and fd write polls
[poll_oneoff_tests]: https://github.com/dunnock/poll_oneoff_tests
* Apply suggestions and negative test for bad fd

* 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
wasi-common
This repo will ultimately serve as a library providing a common implementation of WASI hostcalls for re-use in any WASI (and potentially non-WASI) runtimes such as Wasmtime and Lucet.
The library is an adaption of lucet-wasi crate from the Lucet project, and it is currently based on 40ae1df git revision.
Please note that the library requires Rust compiler version at least 1.37.0.
Supported syscalls
*nix
In our *nix implementation, we currently support the entire WASI API with the exception of socket hostcalls:
sock_recvsock_sendsock_shutdown
We expect these to be implemented when network access is standardised.
We also currently do not support the proc_raise hostcall, as it is expected to
be dropped entirely from WASI.
Windows
In our Windows implementation, we currently support the minimal subset of WASI API which allows for running the very basic "Hello world!" style WASM apps. More coming shortly, so stay tuned!
Development hints
When testing the crate, you may want to enable and run full wasm32 integration testsuite. This
requires wasm32-wasi target installed which can be done as follows using rustup
rustup target add wasm32-wasi
Next initiate submodules containing the integration testsuite
git submodule update --init
Now, you should be able to run the integration testsuite by enabling the wasm_tests feature
cargo test --features wasm_tests
Third-Party Code
Significant parts of our hostcall implementations are derived from the C implementations in
cloudabi-utils. See LICENSE.cloudabi-utils for license information.
