Subject: gRPC: RST_STREAM(NO_ERROR) handling micro-optimization.
X-Git-Tag: release-1.21.1~15
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=693e4134a51b4fd30689ad1e31e6fdffe5ee1429;p=nginx.git

gRPC: RST_STREAM(NO_ERROR) handling micro-optimization.

After 2096b21fcd10, a single RST_STREAM(NO_ERROR) may not result in an error.
This change removes several unnecessary ctx->type checks for such a case.
