This commit simplifies the build script slightly for generating tests by
doing a few dull refactorings:
* Leaves formatting to `rustfmt`
* Extract bulk of code execution into a top-level shared `run_wast`
function so each test is a one-liner
* Use `anyhow` for errors both in the script and in tests
We needed a workaround when using wabt on old Linux distros due to using
old versions of `strtof`. With the switch to `wat`, we no longer need
these workarounds.
* 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.

* 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

* fix Linux `isatty` implementation
* defer `WasiCtxBuilder` errors to `build()`; don't change API yet
This changes the fields on the builder to types that let the various `.arg()`, `.env()`, etc methods
infallible, so we don't have to worry about handling any errors till we actually build. This reduces
line noise when using a builder in a downstream application.
Deferring the processing of the builder fields also has the advantage of eliminating the opening and
closing of `/dev/null` for the default stdio file descriptors unless they're actually used by the
resulting `WasiCtx`.
Unicode errors when inheriting arguments and environment variables no longer cause a panic, but
instead go through `OsString`. We return `ENOTCAPABLE` at the end if there are NULs, or if UTF-8
conversion fails on Windows.
This also changes the bounds on some of the methods from `AsRef<str>` to `AsRef<[u8]>`. This
shouldn't break any existing code, but allows more flexibility when providing arguments. Depending
on the outcome of https://github.com/WebAssembly/WASI/issues/8 we may eventually want to require
these bytes be UTF-8, so we might want to revisit this later.
Finally, this fixes a tiny bug that could arise if we had exactly the maximum number of file
descriptors when populating the preopens.
* make `WasiCtxBuilder` method types less restrictive
This is a separate commit, since it changes the interface that downstream clients have to use, and
therefore requires a different commit of `wasmtime` for testing. That `wasmtime` commit is currently
on my private fork, so this will need to be amended before merging.
Now that failures are deferred until `WasiCtxBuilder::build()`, we don't need to have `Result` types
on the other methods any longer.
Additionally, using `IntoIterator` rather than `Iterator` as the trait bound for these methods is
slightly more general, and saves the client some typing.
* enforce that arguments and environment variables are valid UTF-8
* remove now-unnecessary platform-specific OsString handling
* `ENOTCAPABLE` -> `EILSEQ` for failed arg/env string conversions
* fix up comment style
* Apply @acfoltzer's fix to isatty on Linux to BSD
This commit bumps Cranelift to 0.49.0 and target-lexicon to 0.9.0 to fix the
failing build to due an updated faerie crate that violated semver with an
updated 0.9.0 target-lexicon dependency.
Fixes#491.
* Implement clock_time_get on Windows.
Also update misc_testsuite to include latest clock_time_get test
changes.
* Try to somehow implement clock_res_get on Windows.
* Fix 55ms
* Cache the perf counter resolution
* Fix integration tests
* Bump crate versions.
* Update dependency version numbers too.
This is a follow-up to f96b6c9e72ae50fcddd488be47a2d4b5ac7b926b to
update the version numbers in the local dependencies too.
* Use generated type bindings.
Use the witx API descriptions to generate the bulk of the contents of
host.rs, wasi.rs, and wasi32.rs.
This also prunes out many of the miscellaneous libc definitions from
those files which aren't currently in use by wasi-common. If there's
anything removed that's still needed by someone, it's easy to add things
back in.
* Remove unneeded iovec conversion routines.
* Migrate from failure to thiserror and anyhow
The failure crate invents its own traits that don't use
std::error::Error (because failure predates certain features added to
Error); this prevents using ? on an error from failure in a function
using Error. The thiserror and anyhow crates integrate with the standard
Error trait instead.
This change does not attempt to semantically change or refactor the
approach to error-handling in any portion of the code, to ensure that
the change remains straightforward to review. Modules using specific
differentiated error types move from failure_derive and derive(Fail) to
thiserror and derive(Error). Modules boxing all errors opaquely move
from failure::Error to anyhow. Modules using String as an error type
continue to do so. Code using unwrap or expect continues to do so.
Drop Display implementations when thiserror can easily derive an
identical instance.
Drop manual traversal of iter_causes; anyhow's Debug instance prints the
chain of causes by default.
Use anyhow's type alias anyhow::Result<T> in place of
std::result::Result<T, anyhow::Error> whenever possible.
* wasm2obj: Simplify error handling using existing messages
handle_module in wasm2obj manually maps
cranelift_codegen::isa::LookupError values to strings, but LookupError
values already have strings that say almost exactly the same thing.
Rely on the strings from cranelift.
* wasmtime: Rely on question-mark-in-main
The main() wrapper around rmain() completely matches the behavior of
question-mark-in-main (print error to stderr and return 1), so switch to
question-mark-in-main.
* Update to walrus 0.13 and wasm-webidl-bindings 0.6
Both crates switched from failure to anyhow; updating lets us avoid a
translation from failure to anyhow within wasmtime-interface-types.
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.
This commit syncs `wasmtime-wasi` crate with the latest refactoring
applied to `wasi-common` crate. Namely, `wasm32` is replaced with
two modules: `wasi` and `wasi32`. This change can be tracked via
CraneStation/wasi-common#151.
* 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 PR updates `wasmtime_wasi` crate by adjusting `poll_oneoff`'s
signature to that introduced in `wasi_common` in
CraneStation/wasi-common#137. This change is required in order to
fix#440.
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.
* Switch lightbeam from `wabt` to `wast`
Switch from a C++-based `*.wat` parser to a Rust-based parser
* Remove unneeded `wabt` dev-dependency from wasmtime-api
* Rewrite `wasmtime-wast` crate with `wast-parser`
This commit moves the `wasmtime-wast` crate off the `wabt` crate on to
the `wast-parser` crate which is a Rust implementation of a `*.wast` and
`*.wat` parser. The intention here is to continue to reduce the amount
of C++ required to build wasmtime!
* Use new `wat` and `wast` crate names
* deps: bump wasmparser to 0.39.2
This has a bug fix for multi-value Wasm validation that is required for getting
the spec tests passing.
https://github.com/yurydelendik/wasmparser.rs/pull/135
* Update cranelift to 0.46.1 to get multi-value Wasm support
The `cranelift_wasm` APIs had to change a little bit to maintain state necessary
when translating multi-value Wasm blocks. The `translate_module` function now
returns a `ModuleTranslationState` that is borrowed during each function's
translation.
* Enable multi-value proposal's spec tests
This enables all the Wasm multi-value proposal's spec tests other than the ones
that rely on functions having more return values than registers available on the
target. That is not supported by cranelift yet.
* wasmtime-interface-types: always use multi-value Wasm
And remove the return pointer hacks that work around the lack of multi-value.
* 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
In trying to build the lightbeam feature in wasmtime there are
compile errors mostly related to outdated or missing trait
definitions. This patch moves the current cranelift codegen
dependence to 0.44 in support of that, though other changes
are still needed in wasmtime to get the feature to build.
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).
