* Tidy up the `hello` example for `wasmtime`
* Remove the `*.wat` and `*.wasm` files and instead just inline the
`*.wat` into the example.
* Touch up comments so they're not just a repeat of the `println!`
below.
* Move `*.wat` for `memory` example inline
No need to handle auxiliary files with the ability to parse it inline!
* Move `multi.wasm` inline into `multi.rs` example
* Move `*.wasm` for gcd example inline
* Move `*.wat` inline with `import_calling_export` test
* Remove checked in `lightbeam/test.wasm`
Instead move the `*.wat` into the source and parse it into wasm there.
* Run rustfmt
This commit is an attempt to reduce the number of crates necessary to
link to when using `wasmtime::Config` in "default mode" or with only one
or two tweaks. The change moves to a builder-style pattern for `Config`
to only require importing crates as necessary if you configure a
particular setting. This then also propagates that change to `Context`
as well by taking a `Config` instead of requiring that all arguments are
passed alone.
For some weird reason (probably when migrating the codebase from
`wasi-common` repo to `wasmtime`), these did not get enabled for the
Windows platform.
This commit adds a relatively complete test case for the `path_link`
syscall. This commit should serve as some prep work for implementing
`path_link` on Windows (which will follow in a subsequent PR).
This commit enables the multi-value features in the Python extension
to be usable by-default with interface types. Additionally this removes
some code which panics on multi-value but doesn't end up getting used
today.
* Cover `cargo wasi`
* Cover a "Hello, world!" binary
* Cover a "Hello, world!" library
* Cover a more advanced example with WebAssembly interface types
* Importing/exporting functionality basics
* Allow using WASI APIs in the Python extension
This commit adds support to the Python extension to load the WASI
implementation when a WASI module is seen allowing Python to load
WebAssembly modules that use WASI. This is pretty primitive right now
because there's no way to configure the environment/args/preopens/etc,
but it's hoped to be at least a start!
* rustfmt
* Refactor checks for the wasi module name
* Move the check into `wasmtime-wasi` itself
* Make it conservative for now and match anything that says `wasi*`
* Leave a `FIXME` for improving this later on
* Enable missing feature of winapi for `winx`
* Dynamically load utimensat if exists on the host
This commit introduces a change to file time management for *nix based
hosts in that it firstly tries to load `utimensat` symbol, and if it
doesn't exist, then falls back to `utimes` instead. This change is
borrowing very heavily from [filetime] crate, however, it introduces a
couple of helpers and methods specific to WASI use case (or more
generally, to a use case which requires modifying times of entities
specified by a pair `(DirFD, RelativePath)` rather than the typical
file time specification based only absolute path or raw file descriptor
as is the case with [filetime] crate. The trick here is, that on kernels
which do not have `utimensat` symbol, this implementation emulates this
behaviour by a combination of `openat` and `utimes`.
This commit also is meant to address #516.

* Fix symlink NOFOLLOW flag setting
* Add docs and specify UTIME_NOW/OMIT on Linux
Previously, we relied on [libc] crate for `UTIME_NOW` and `UTIME_OMIT`
constants on Linux. However, following the convention assumed in
[filetime] crate, this is now changed to directly specified by us
in our crate.

* Refactor UTIME_NOW/OMIT for BSD
* Address final discussion points
* Reduce duplication in error messages
This commit removes duplication in error messages where the same text
would show up multiple times in a fully rendered error message.
When using `derive(Error)` when the `#[from]` attribute is used there's
no need to also render that payload into the error string because the
`#[from]` establishes a "backtrace" which means that when the full
context of an error is rendered it will include the `#[from]` in the
lower frames of the backtrace anyway.
This commit audits the `derive(Error)` implementations to avoid
duplication in the rendered error messages, ensuring that if `#[from]`
is used then the `#[from]` field isn't also rendered in the textual
description.
* Search the full error in wast assertions
Don't just search the top error, but search the whole backtrace by using
the `{:?}` format instead of `{}`.
A small amount of cleanup for the top-level of this repository, where
the `installer` directory just had one misc file for the Windows
installer which we can put elsewhere inside of `ci`, another misc folder
but one that already has a few files in it.
* General Cargo.toml cleanup.
- Remove travis-ci attributes.
- Remove "experimental" badges from actively-developed crates.
- Reflow some long lines.
- Use dependency features consistently.
- Add readme attributes
* Update WASI to the latest trunk.
This notably adds a .gitignore file for the WASI directory.
* Refactor Lightbeam's tests.
This refactors Lightbeam's tests.rs file into several pieces, separating
quickcheck tests into their own file, and moving tests which can be run as
wast tests into `tests/misc_testsuite`, and creating a tests directory
for the rest.
* Remove the old filetests tests.
These are all covered by misc_testsuite and spec_testsuite tests.
* rustfmt
* Remove the "bench" feature.
