The prior policy excluded post-TCP SOCKS5 phases (NEGOTIATION / AUTHENTICATION / CONNECT_RELAY) and labeled PROXY_TCP_CONNECT on the "structurally identical to a socket-open failure" rationale (98483bbe06, b3da5031af). That rule conflated failure mechanism with semantic attribution: backpressure is about WHICH party is overloaded, not WHAT kind of failure surfaces. Re-frame: a SOCKS5 failure is mongod-attributable only when the proxy acted as a reach-proxy for mongod and reported a transport-level outcome that mirrors a direct-connection socket-open failure. That is exactly CONNECT_RELAY with RFC 1928 reply codes 3 (network unreachable), 4 (host unreachable), or 5 (connection refused) — the SOCKS5 analogs of NoRouteToHostException and ConnectException. Policy changes: - PROXY_TCP_CONNECT flips from labeled to NOT labeled — the proxy itself is unreachable; mongod was never reached. - CONNECT_RELAY with codes 3, 4, or 5 flips from NOT labeled to LABELED — these mirror direct-connection mongod-overload signals. - NEGOTIATION, AUTHENTICATION, CONNECT_RELAY with codes 1, 2, 6, 7, 8, and CONNECT_RELAY with null replyCode (I/O failure / unrecognised reply) remain NOT labeled — proxy-side or ambiguous failures with no mongod-side attribution. Rename isExcludedSocksPostTcpPhase -> isNonMongodAttributableSocksFailure to reflect the actual semantic and add reply-code-aware logic. Update MongoSocksProxyException class Javadoc and the labeler method Javadoc to describe the attribution rule. Test recalibration: - socksProxyPostTcpPhaseShouldNotBeLabeled split and renamed: socksProxyNonMongodAttributableShouldNotBeLabeled (9 cases) and socksProxyMongodAttributableShouldBeLabeled (3 cases for codes 3/4/5). - Old socksProxyTcpConnectPhaseShouldBeLabeled removed; PROXY_TCP_CONNECT is now covered as the first case of the non-attributable parameterised test. This inverts the explicit Round 2 decision documented in 98483bbe06 and the matching class-level Javadoc updated in b3da5031af. --- .../com/mongodb/MongoSocksProxyException.java | 24 ++++--- .../connection/BackpressureErrorLabeler.java | 45 ++++++++++--- .../BackpressureErrorLabelerTest.java | 67 +++++++++++++++---- 3 files changed, 104 insertions(+), 32 deletions(-) diff --git a/driver-core/src/main/com/mongodb/MongoSocksProxyException.java b/driver-core/src/main/com/mongodb/MongoSocksProxyException.java index 8076831d5a1..f1c3eece866 100644 --- a/driver-core/src/main/com/mongodb/MongoSocksProxyException.java +++ b/driver-core/src/main/com/mongodb/MongoSocksProxyException.java @@ -23,14 +23,22 @@ /** * Thrown when an error occurs while establishing a connection to a SOCKS5 proxy. * - *
