* Remove dependency on `more-asserts`
In my recent adventures to do a bit of gardening on our dependencies I
noticed that there's a new major version for the `more-asserts` crate.
Instead of updating to this though I've opted to instead remove the
dependency since I don't think we heavily lean on this crate and
otherwise one-off prints are probably sufficient to avoid the need for
pulling in a whole crate for this.
* Remove exemption for `more-asserts`
* Port wasi-common to io-lifetimes.
This ports wasi-common from unsafe-io to io-lifetimes.
Ambient authority is now indicated via calls to `ambient_authority()`
from the ambient-authority crate, rather than using `unsafe` blocks.
The `GetSetFdFlags::set_fd_flags` function is now split into two phases,
to simplify lifetimes in implementations which need to close and re-open
the underlying file.
* Use posish for errno values instead of libc.
This eliminates one of the few remaining direct libc dependencies.
* Port to posish::io::poll.
Use posish::io::poll instead of calling libc directly. This factors out
more code from Wasmtime, and eliminates the need to manipulate raw file
descriptors directly.
And, this eliminates the last remaining direct dependency on libc in
wasi-common.
* Port wasi-c-api to io-lifetimes.
* Update to posish 0.16.0.
* Embeded NULs in filenames now get `EINVAL` instead of `EILSEQ`.
* Accept either `EILSEQ` or `EINVAL` for embedded NULs.
* Bump the nightly toolchain to 2021-07-12.
This fixes build errors on the semver crate, which as of this writing
builds with latest nightly and stable but not 2021-04-11, the old pinned
version.
* Have cap-std-sync re-export ambient_authority so that users get the same version.
This commit updates _all_ WASI test programs to use the latest
version of the `wasi` crate (`v0.9.0`). While at it, it also
unifies asserting error conditions across all test programs.
* Move `wasi` to `wasi_old` in wasi-tests
Leave space for the new `wasi` crate but allow us to incrementally
update tests.
* Update the big_random_buf test
* Update clock_time_get test
* Update close_preopen test
* Review comments
* Update to latest Wasmtime API
* Reorganize wasi-misc-tests.
Move wasi-misc-tests out of wasi-common, to break a dependency cycle;
previously, wasmtime-* depended on wasi-common, but wasi-common
dev-dependended on wasmtime-*.
Now, wasi-common no longer dev-depends on wasmtime-*; instead, the
tests are in their own crate which depends on wasi-common and on
wasmtime-*.
Also, rename wasi-misc-tests to wasi-tests for simplicity.
This also removes the "wasm_tests" feature; it's replaced by the
"test-programs" feature.
* Update the CI script to use the new feature name.
* Update the CI script to use the new feature name in one more place.
* Change a `write!` to a `writeln!`.
