Good day. It's August 6th, and here's what moved in the Redis codebase.
The clearest thread today is memory safety in code paths that juggle ownership across operations. PR 15594 from ShooterIT fixes a use-after-free in handle-clients-blocked-on-key: reprocessing one blocked client could trigger client eviction, which freed a list node another iterator still held. The fix replaces the…
Second theme: release pipeline hardening. PR 15596 switches release tooling — the tarball test script, the upload step, and the hash publisher — from plain HTTP to HTTPS when talking to download-dot-redis-dot-io. Without that, an on-path attacker could have swapped in a malicious Makefile or test runner during the…
Rounding out the day: a flaky test fix. PR 15585 from plusky pins down a lazy-free stream test that failed intermittently because its effort estimate depended on how fast the machine issued a thousand XADDs. Using explicit millisecond-spaced stream IDs makes the test deterministic across hardware. And a small typo…
What to remember: ownership and lifecycle bugs are this week's pattern, not one-off mistakes. If you're touching blocking clients, hash field expiry, or command accounting, check…
