Good morning, it's September 21st, 2026.
The signal today is locking and reliability, with the highest-impact fix preventing an unrecoverable hang in the standard database package.
First, deadlocks. In pull request 81615, a transaction on a database connection holds a read lock for the life of that transaction, only releasing on commit or rollback. If low-level raw access on that same connection then reported a bad connection, the cleanup path tried to take a write lock from the same goroutine…
Related, but test-only, pull request 81624 deflakes the runtime test for finalizer or cleanup deadlock. Those tests were intermittently failing with stack unavailable errors because panic traces don't stop the world, and the finalizer could still be starting up when the panic fired. A short ten-millisecond pause…
