Hello, it's November third, twenty twenty-six, with your Redis developer update.
The throughline today is hardening the core: two merged fixes close memory corruption paths, two redis-cli patches tighten handling of bad or empty input, all while a high-risk proposal to bring Bloom filters in-core waits for review.
First, storage safety. Pull request sixteen one twenty-five fixes a use-after-free in Z-range-store when source and destination are the same key. With key memory histograms or cluster slot stats enabled, the range command sampled the source size, then the store deleted or replaced that same object mid-operation,…
Related is pull request sixteen one forty-six, which rejects duplicate key metadata classes on load. Previously only a debug assert caught repeats, which disappears in release builds, so a crafted restore payload or R-D-B could overrun the allocated metadata slots. Now repeated classes fail the load.
Second, client resilience. Pull request sixteen one seventeen bounds legacy help building in redis-cli, scanning at most four thousand ninety-six command entries and ignoring arities outside plus or minus one thousand twenty-four, closing a resource exhaustion risk…
