Redis: Clock Races, Restart Safety, and CLI Fixes
A merged fix moves blocking timeouts and module timers to monotonic time to resolve a race exposed by the processor-clock change. Open proposals address restart descriptor leaks, stalled crash reports, and redis-cli protocol and IPv6 handling.

Good morning, this is your Redis briefing for Tuesday, September 29th, 2026.
The headline is clocks. A switch to processor-based monotonic time exposed a long-standing race between blocking timeouts and module timers, now fixed for more predictable behavior.
First, core predictability. In pull request 15743, merged yesterday, blocking commands and module-blocked clients plus module timers now share the same monotonic deadline instead of mixing wall-clock and microsecond clocks. That mixing let a blocked client time out just before a module timer with the same 100…
Second, command-line usability. Pull request 15888 tracks the selected protocol across reconnects, so an explicit Resp 2 session stays on Resp 2 instead of flipping back to Resp 3 when the server default is Resp 3. Pull request 15890 fixes cluster address parsing to accept standard bracketed I-P-v-6 endpoints, which…
Finally, accounting and release hygiene. Pull request 15887 reconciles per-slot memory accounting after stream expiry, a counter fix not a physical heap leak. Merged pull request 15877 names release bundles with their version tag to stay distinct from automatic source archives, and pull request 15853 corrects…
