* Update tracing-core to a version which doesn't depend on lazy-static.
* Update crossbeam-utils to a version that doesn't depend on lazy-static.
* Update crossbeam-epoch to a version that doesn't depend on lazy-static.
* Update clap to a version that doesn't depend on lazy-static.
* Convert Wasmtime's own use of lazy_static to once_cell.
* Make `GDB_REGISTRATION`'s comment a doc comment.
* Fix compilation on Windows.
* Upgrade all crates to the Rust 2021 edition
I've personally started using the new format strings for things like
`panic!("some message {foo}")` or similar and have been upgrading crates
on a case-by-case basis, but I think it probably makes more sense to go
ahead and blanket upgrade everything so 2021 features are always
available.
* Fix compile of the C API
* Fix a warning
* Fix another warning
Modify the `poll_oneoff_files` test to avoid assuming that `poll_oneoff`
returns all pending events, as it may sometimes return only a subset of
events. When multiple events are expected, use a loop, and loop until
all events have been recorded.
* 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 increases the timeout from 50ms to 200ms, which makes the
tests reliably pass on my machine using the CI scripts againt
the s390x-linux-user qemu target.
Add support for `poll_oneoff` calls which just sleep on a relative
timeout. This fixes a bug handling code compiled with WASI libc's `sleep`
family of functions, which call `poll_oneoff` with a `CLOCK_REALTIME`
timer, which wasn't previously implemented.
