Matthias Krüger 43297ffc22 Rollup merge of #138581 - Zoxc:abort-handler-if-locked, r=SparrowLii
Abort in deadlock handler if we fail to get a query map

Resolving query cycles requires the complete active query map, or it may miss query cycles. We did not check that the map is completely constructed before. If there is some error collecting the map, something has gone wrong already. This adds a check to abort/panic if we fail to construct the complete map.

This can help differentiate errors from the `deadlock detected` case if constructing query map has errors in practice.

An `Option` is not used for `collect_active_jobs` as the panic handler can still make use of a partial map.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
