Instead of inheriting stdio, pass in explicit file paths that are opened for
reading (stdin) or writing (stderr/stdout). This will allow sightglass to assert
that benchmarks produce the expected output.
* wasmtime-wasi: re-exporting this WasiCtxBuilder was shadowing the right one
wasi-common's WasiCtxBuilder is really only useful wasi_cap_std_sync and
wasi_tokio to implement their own Builder on top of.
This re-export of wasi-common's is 1. not useful and 2. shadow's the
re-export of the right one in sync::*.
* wasi-common: eliminate WasiCtxBuilder, make the builder methods on WasiCtx instead
* delete wasi-common::WasiCtxBuilder altogether
just put those methods directly on &mut WasiCtx.
As a bonus, the sync and tokio WasiCtxBuilder::build functions
are no longer fallible!
* bench fixes
* more test fixes
This adds benchmarks around module instantiation using criterion.
Both the default (i.e. on-demand) and pooling allocators are tested
sequentially and in parallel using a thread pool.
Instantiation is tested with an empty module, a module with a single page
linear memory, a larger linear memory with a data initializer, and a "hello
world" Rust WASI program.
* Upgrade to the latest versions of gimli, addr2line, object
And adapt to API changes. New gimli supports wasm dwarf, resulting in
some simplifications in the debug crate.
* upgrade gimli usage in linux-specific profiling too
* Add "continue" statement after interpreting a wasm local dwarf opcode
On Windows, `metadata` computes only partial metadata results, which don't
include what WASI needs for the `inode` field in `readdir` results. cap-std
has a `full_metadata` function which is able to include this extra
information, however it has more strict access requirements, so it sometimes
fails even when plain `metadata` would succeed.
Make WASI's `readdir` silently skip over files that can't be accessed by
`full_metadata`. These files wouldn't be openable in any other way by
WASI programs, so the only benefit of listing them would be to
let applications know that they exist. This allows it to avoid failing
and avoid returning bogus results.
This is part of a fix for bytecodealliance/cap-std#169.
This commit implements the `--allow-unknown-exports` option to the CLI run
command that will ignore unknown exports in a command module rather than
return an error.
Fixes#2587.
