This has been integrated into `anyhow::Error` already upstream andmeans that we can remove our own local hacks such as the `Err2Anyhow` trait.This commit removes the `Err2Anyhow` trait and all usage, going back toidiomatic Rust error propagation and conversion even in the `no_std`world. This should make code more portable by default and remove someweird idioms we had for supporting this.prtest:full* Add some trusted vets* Audit object crate update* Disable backtraces on CI List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/byte_count.rs Tue, 03 Dec 2024 18:27:28 +0000 Alex Crichton <alex@alexcrichton.com> http://172.16.0.5:8080/history/wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/byte_count.rs#d5db7a68 Move memory pool over to aligned byte counts (#9668)* Move memory pool over to aligned byte countsPart of work to centralize memory management within Mmap instances -- some ofthat work becomes easier if the byte counts are known to be aligned.There were a few overflow cases that I added checks for.* Address review comments* Fix unused code warnings List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/byte_count.rs Mon, 25 Nov 2024 20:15:56 +0000 Rain <rain@sunshowers.io> http://172.16.0.5:8080/history/wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/byte_count.rs#74a703b2 Add HostAlignedByteCount to enforce alignment at compile time (#9620)* Add HostAlignedByteCount to enforce alignment at compile timeAs part of the work to allow mmaps to be backed by other implementations, Irealized that we didn't have any way to track whether a particular usize ishost-page-aligned at compile time.Add a `HostAlignedByteCount` which tracks that a particular usize is aligned tothe host page size. This also does not expose safe unchecked arithmeticoperations, to ensure that overflows always error out.With `HostAlignedByteCount`, a lot of runtime checks can go away thanks to thetype-level assertion.In the interest of keeping the diff relatively small, I haven't convertedeverything over yet. More can be converted over as time permits.* Make zero-sized mprotects a no-op, add tests List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/byte_count.rs Fri, 22 Nov 2024 00:23:19 +0000 Rain <rain@sunshowers.io>
