Good morning, it's October 8th, 2026. You're listening to Redis Daily.
Lead insight: today's activity is about preventing silent failures — losing the only on-disk data file on startup, registering the wrong script function by chance, and spinning Sentinel in a busy loop.
First theme: persistence and scripting correctness. In PR 15916, when the preload file pointed to the local legacy append-only file with append-only mode on, an upgrade step moved the source before the setup-after-preload step ran. That setup then deleted the target and looked for the original path, which no longer…
Related, PR 15884 fixes function name collisions. Names were case-sensitive inside a library but case-insensitive globally, so a library could register both foo and capital-F-O-O, with chance deciding which one was actually reachable. The fix makes the per-library registry case-insensitive, overwriting with a…
Second theme: connections and hot-path efficiency. PR 15917 ports a hiredis fix for Linux TCP connect. A stale entry left in the socket error queue after a successful connect could put Sentinel into a busy loop. The change drains that queue when connect is pending or complete while preserving the…
