Mon, 30 Mar 2026 18:35:31 +0000

Handle OOM in the rest of Wasmtime's non-component, -async, -compilation APIs (#12858)* Handle OOM in more places in the public APIA bunch of random places:* Add: `Trap::try_new` to handle OOM while creating traps* Use: `TryVec` inside `Func::call_impl_do_call` and `wasm_val_raw_storage` to hold the args and rets* Add: `Instance::try_exports` for iterating over an instance's exports while handling OOM* `Linker:try_get`, like `Linker::get` but handling OOM* `Linker:try_get_by_import`, like `Linker::get_by_import` but handling OOM* Use `try_new` to box things in `SharedMemory::new`* Use `TryVec` instead of `Vec` in our dynamic tables* Add OOM tests for most of Wasmtime's public APIExcludes component-, async-, and compilation-related APIs.* address review feedback* fix test compilation* fix c-api List of files: /wasmtime-44.0.1/crates/core/src/alloc/vec.rs

2283e84f - Fix a panic with a massive `max_wasm_stack` configured (#12869)

Mon, 30 Mar 2026 18:32:56 +0000

Fix a panic with a massive `max_wasm_stack` configured (#12869)* Fix a panic with a massive `max_wasm_stack` configuredThis commit fixes a panic through a `checked_add(...).unwrap()` whichcan happen when `Config::max_wasm_stack` is configured to be a verylarge value. This is a mostly benign panic as it's unlikely this isconfigured much in the wild, but nevertheless seems like a good issuesto fix regardless.* Fix an overflow/OOM panic in pulleyprtest:full* Fix CI* Another CI fix* Fix test on 32-bit* Fix miri test List of files: /wasmtime-44.0.1/crates/core/src/alloc/vec.rs

Tue, 03 Feb 2026 19:27:54 +0000

Add fallible `try_collect` to collections (#12505)* Add fallible `try_collect` to collectionsThis adds a new `TryCollect` extension trait to `wasmtime-core` whichenables `iter.try_collect()` to fallibly collect into a `Vec` or`Box<[T]>` while handling OOM. This is intended to serve as areplacement for the `new_boxed_slice_*` helpers in appropriatesituations since it more closely matches what Wasmtime likely alreadydoes today where we throw `.collect()` on iterators.* Extend oom tests a bit more* Use a TryExtend trait* Fix oom tests List of files: /wasmtime-44.0.1/crates/core/src/alloc/vec.rs
