What is the goal of this project? #11
Comments

It's still evolving :-). I think it's useful to have a simple runner program for executables, but ideally the libraries should be usable in other applications as well. |

* 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 rust-lang/libc#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.

- [Commits](rust-lang/libc@0.2.62...0.2.65)

* Fix compilation error
* Enable Actions and add rust.yml (#35)
* Enable Actions and add rust.yml
This commit enables Github Actions and adds corresponding configuration in rust.yml file.
* Update rust.yml
* Fix formatting
* Add empty .rustfmt.toml config file
* Add badge to README
* Update README
* Clean up Github Actions and README
* 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
Co-authored-by: Maxim Vorobjov <maxim.vorobjov@gmail.com>
* 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

* Adds support for flags datatype This commit adds support for `FlagsDatatype`. In WASI, flags are represented as bitfields/bitflags, therefore, it is important for the type to have bitwise operations implemented, and some way of checking whether the current set of flags contains some other set (i.e., they intersect). Thus, this commit automatically derives `BitAnd`, etc. for the derived flags datatype. It also automatically provides an `ALL_FLAGS` value which corresponds to a bitwise-or of all flag values present and is provided for convenience. * Simplify read_from_guest

This adds a `poll_oneoff` implementation to src/lib.rs. It's completely untested. I was planning on adding a host implementation and using that to test end-to-end, but that raised some tough questions about how much of the existing `wasi-common` scheduler(s) should be reused. I've decided to focus on other, more widely-used parts of WASI first, but I wanted to share the work I've already done here. Note that I've moved the clock- and socket-specific functions out of `wasi-poll` and into `wasi-clocks` and `wasi-tcp`, respectively. The latter is a new interface which will eventually contain functions and types resembling @npmccallum's https://github.com/npmccallum/wasi-snapshot-preview2#wasi-tcp proposal. Per discussion with @sunfishcode: - `wasi-tcp` includes an `error` enum type, intended to represent only socket-related errors. - It also includes a `socket` pseudo-handle type, distinct from `wasi-filesystem`'s `descriptor` type. These fine-grained types help move us away from the "everything is a file descriptor" and "all errors are errnos" approaches of Preview 1. If we decide `poll-oneoff` should be usable with files as well as sockets, we can add `subscribe-read` and `subscribe-write` functions to `wasi-filesystem` which accept file `descriptor`s. Likewise for any other pseudo-handle type from which we'd like to create futures. Signed-off-by: Joel Dice <joel.dice@fermyon.com> Signed-off-by: Joel Dice <joel.dice@fermyon.com>

This patch fixes an unused variable warning triggered in
`continuation.rs` when compiling in release mode.
```

What does the description means?
"Standalone JIT-style runtime support for WebAsssembly code in Cranelift"
Can I use this project as substitute for
wasmi? Like instantiate a module providing imports (satisfied by other modules and/or host functions), and execute exports.Or is it for running wasm executables (something like cervus)?
