Bump github.com/redis/go-redis/v9 from 9.20.0 to 9.20.1

[dependabot]

Bumps github.com/redis/go-redis/v9 from 9.20.0 to 9.20.1.

Release notes

Sourced from github.com/redis/go-redis/v9's releases.

9.20.1

This is a patch release containing bug fixes only. There are no new features or breaking changes; upgrading from 9.20.0 is a drop-in replacement.

🚀 Highlights

RESP3 pub/sub message loss fixed

PeekPushNotificationName previously inspected only the bytes already buffered by bufio, so when a push frame header straddled a buffer fill boundary it could return a truncated notification name (e.g. "messa" instead of "message"). The push processor then mis-routed the frame and ReadReply silently dropped it, causing intermittent RESP3 pub/sub message loss. The peek now grows its window (36 bytes → up to 4 KiB) and reads more from the connection until the header is complete, cleanly separating incomplete prefixes from corrupt frames (including overflow-safe bulk-length handling). Fixes #3839.

🐛 Bug Fixes

• RESP3 push peeking: PeekPushNotificationName no longer returns a truncated notification name when a push frame header spans a buffer boundary, preventing silent RESP3 pub/sub message loss (fixes #3839) (#3842) by @​ndyakov
• FT.HYBRID vector params: Vector data is now always sent via PARAMS with auto-generated param names (__vector_param_N, with collision avoidance) when VectorParamName is omitted, since Redis no longer accepts inline vector blobs; the FTHybridOptions.Params map is no longer mutated, so the same options struct can be reused across calls (#3844) by @​ndyakov
• CLUSTER SHARDS forward compatibility: Unknown shard- and node-level attributes in the CLUSTER SHARDS reply are now skipped via DiscardNext() instead of erroring, so clients keep working when the server introduces new fields (#3843) by @​madolson
• PubSub double reconnect: PubSub.releaseConn no longer reconnects twice when a connection is both unusable (or pending handoff) and reports a bad-connection error, avoiding a wasted connection establish-then-close cycle (#3833) by @​cxljs
