The `build.rs`script for the `wasmtime` crate will now detect the target platform andauto-enable this feature as necessary.The `signals-based-traps` cargo feature is removed and split into twocustom `#[cfg]` directives that the build script sets:* `has_virtual_memory` - this is used to gate mmap implementations for example. This is enabled on `unix || windows` and will be off for `no_std` targets for example. This is split out of "signals-based-traps" to better handle platforms like iOS which have virtual memory but don't execute native code (removing the need for native signals).* `has_native_signals` - gates signal handlers on Unix for example. This is disabled on MIRI but otherwise enabled for `unix || windows`. This is intended to in the future get disabled for iOS by default for example since it's not necessary when using Pulley. This is additionally off-by-default for `no_std` platforms.Two new crate features were added for `no_std` or "custom" platforms toopt-in to the `wasmtime-platform.h` C APIs for implementing virtualmemory and signals. These are used in the `min-platform` embedding example.This commit additionally updates some various documentation here andthere to be more up-to-date.* Update CI configuration* Fix compile warnings* Fix test on miri* Fix more tests on miri* Fix some warnings* Another round of miri/CI attempts/fixesprtest:full List of files: /wasmtime-44.0.1/examples/min-platform/README.md Wed, 15 Jan 2025 01:15:14 +0000 Alex Crichton <alex@alexcrichton.com> http://172.16.0.5:8080/history/wasmtime-44.0.1/examples/min-platform/README.md#72004aad Turn the `wasmtime-runtime` crate into the `wasmtime::runtime::vm` module (#8501)* Expose `wasmtime-runtime` as `crate::runtime::vm` internally for the `wasmtime` crate* Rewrite uses of `wasmtime_runtime` to `crate::runtime::vm`* Remove dep on `wasmtime-runtime` from `wasmtime-cli`* Move the `wasmtime-runtime` crate into the `wasmtime::runtime::vm` module* Update labeler for merged crates* Fix `publish verify`prtest:full List of files: /wasmtime-44.0.1/examples/min-platform/README.md Tue, 30 Apr 2024 18:52:45 +0000 Nick Fitzgerald <fitzgen@gmail.com> http://172.16.0.5:8080/history/wasmtime-44.0.1/examples/min-platform/README.md#b81bb7a3 Add a "custom" platform configuration for Wasmtime (#7995)* Add a "custom" platform configuration for WasmtimeThis commit leverages adds a new "platform" to Wasmtime to be supportedin the `crates/runtime/src/sys` folder. This joins preexisting platformssuch as Unix and Windows. The goal of this platform is to be an opt-inway to build Wasmtime for targets that don't have a predefined way torun.The new "custom" platform requires `--cfg wasmtime_custom_platform` tobe passed to the Rust compiler, for example by using `RUSTFLAGS`. Thisnew platform bottoms out in a C API that is intended to be small andLinux-like. The C API is effectively the interface to virtual memorythat Wasmtime requires. This C API is also available as a header file at`examples/min-platform/embedding/wasmtime-platform.h` (generated by`cbindgen`).The main purpose of this is to make it easier to experiment with portingWasmtime to new platforms. By decoupling a platform implementation fromWasmtime itself it should be possible to run these experimentsout-of-tree. An example of this I've been working on is gettingWasmtime running on bare-metal with a custom kernel. This supportenables defining the platform interface of the custom kernel's syscallsoutside of Wasmtime.* Exclude wasmtime-platform.h from formatting* Include build-wasmtime-target-wasm32 in final job* Don't force any single toolchain* Add notes to no_std docs* Add rust-src to CI* Review comments* Change APIs to be fallible* Only compile the min-platform example on Linux* Fix compile of min-platform example* Fix another compile error in the example List of files: /wasmtime-44.0.1/examples/min-platform/README.md Wed, 28 Feb 2024 20:23:33 +0000 Alex Crichton <alex@alexcrichton.com>
