Redis: Silent Overwrites, Drift, and FreeBSD Fixes
Core fixes address silent wrong-key writes, lost notification config, and background-free mismatches. The pattern is divergence without errors, plus FreeBSD stability and native-structure efficiency work ahead of 8.12 RC2.

Hello, today is November 2nd, 2026 with your Redis daily brief.
The biggest signal is silent divergence — cases where primary, replica, or disk state quietly drift apart with no error.
First, wrong-key risk in the core. Pull request 16121 fixes reuse of stale dictionary entry links. Any lookup can trigger a rehash step, and during a shrink that step can push other entries ahead of a saved link. Code that held the link across a second lookup, a keyspace notification, or a module hook could then…
Second, config and replica drift. Pull request 16142 fixes keyspace notifications where the new-key, overwritten, and type-changed flags were hidden when all-events was set. They still fired, but a config rewrite saved the shortened string, so after a restart those events silently stopped. Open request 16140 reports…
Finally, efficiency and platform stability. Pull request 16062 stops the bundled allocator from hijacking system hooks on FreeBSD, fixing thread-exit leaks and fork deadlocks around background saves. And pull request 16143 skips building a full Top-K snapshot payload when there is no propagation target, part of a…
What's next: watch the open stream propagation and metadata…
