Wasmtime GitHub notifications bot (Nov 20 2024 at 20:13): Wasmtime GitHub notifications bot (Nov 20 2024 at 20:13):sunshowers opened PR #9639 from sunshowers:mmap-aligned to bytecodealliance:main:
In the wasmtime codebase there are two kinds of mmaps: those that are always backed by anonymous memory and are always aligned, and those that are possibly file-backed and so the length might be unaligned. In https://github.com/bytecodealliance/wasmtime/pull/9620 I accidentally mixed the two up in a way that was a ticking time bomb.
To resolve this, add a type parameter to
Mmapto distinguish between the cases. All of wasmtime's users are clearly either one or the other, so it's quite simple in the end.
