From 76791d6e6c9b3501677fc791e7bca324275febcd Mon Sep 17 00:00:00 2001 From: sneak Date: Mon, 21 Sep 2026 07:59:46 +0000 Subject: [PATCH] Rewrite script/test to the canonical race-enabled pattern (closes #67) script/test now runs `go test -timeout 30s -race -cover ./...`, quiet on success and rerunning verbose with `exit 1` on failure, per policy. -race surfaced a real data race on the process-global apex/log logger: Init reconfigures it (SetHandler/SetLevel) each CLI run while other goroutines read it to log. internal/log now mutates the global under the write lock and reads it under the read lock (new emit helper, DebugReal), and drops WithError, whose returned Entry logged outside that lock. That Entry was also the only thing printing a failed command's error to stderr, so run() now reports it via log.Errorf (shown under -q too). The corruption fuzz test shrinks (20000->1500 files, 500->100 iters) to keep the suite under 20s with -race.
