Overview

The release provides a new unmarshal option for limiting the recursion depth when unmarshalling nested messages to prevent stack overflows. (UnmarshalOptions.RecursionLimit).

Notable changes

New features:

• CL/340489: testing/protocmp: add Message.Unwrap

Documentation improvements:

• CL/339569: reflect/protoreflect: add more docs on Value aliasing

Updated supported versions:

• CL/370055: all: update supported versions

UnmarshalOption RecursionLimit

• CL/385854: all: implement depth limit for unmarshalling

The new UnmarshalOptions.RecursionLimit limits the maximum recursion depth when unmarshalling messages. The limit is applied for nested messages. When messages are nested deeper than the specified limit the unmarshalling will fail. If unspecified, a default limit of 10,000 is applied.

In addition to the configurable limit for message nesting a non-configurable recursion limit for group nesting of 10,000 was introduced.

Upcoming breakage changes

The default recursion limit of 10,000 introduced in the release is subject to change. We want to align this limit with implementations for other languages in the long term. C++ and Java use a limit of 100 which is also the target for the Go implementation.
