We define MessageState, which is essentially an atomically set *MessageInfo. By nesting this as the first field in every generated message, we can implement the reflective methods on a *MessageState when obtained by unsafe casting a concrete message pointer as a *MessageState. The MessageInfo held by MessageState provides additional Go type information to interpret the memory that comes after the contents of the MessageState. Since we are nesting a MessageState in every message, the memory use of every message instance grows by 8B. On average, the body of ProtoReflect grows from 133B to 202B (+50%). However, this is offset by XXX_Methods, which is 108B and will be removed in a future CL. Taking into account the eventual removal of XXX_Methods, this is a net reduction of 25%. name old time/op new time/op delta Name/Value-4 70.3ns ± 2% 17.5ns ± 6% -75.08% (p=0.000 n=10+10) Name/Nil-4 70.6ns ± 3% 33.4ns ± 2% -52.66% (p=0.000 n=10+10) name old alloc/op new alloc/op delta Name/Value-4 16.0B ± 0% 0.0B -100.00% (p=0.000 n=10+10) Name/Nil-4 16.0B ± 0% 0.0B -100.00% (p=0.000 n=10+10) name old allocs/op new allocs/op delta Name/Value-4 1.00 ± 0% 0.00 -100.00% (p=0.000 n=10+10) Name/Nil-4 1.00 ± 0% 0.00 -100.00% (p=0.000 n=10+10) Change-Id: I92bd58dc681c57c92612fd5ba7fc066aea34e95a Reviewed-on: https://go-review.googlesource.com/c/protobuf/+/185460 Reviewed-by: Damien Neil <dneil@google.com>
