From a08d87d0f32b72aa88ea73033958d724ae234f67 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 14 Apr 2026 22:04:43 +0000 Subject: [PATCH] =?UTF-8?q?fix:=20investigation:=20CI=20exhaustion=20patte?= =?UTF-8?q?rn=20on=20chat=20sub-issues=20#707=20and=20#712=20=E2=80=94=203?= =?UTF-8?q?+=20failures=20each=20(#742)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two bugs in agent-smoke.sh caused non-deterministic CI failures: 1. SIGPIPE race with pipefail: `printf | grep -q` fails when grep closes the pipe early after finding a match, causing printf to get SIGPIPE (exit 141). With pipefail, the pipeline returns non-zero even though grep succeeded — producing false "undef" failures. Fixed by using here-strings (<<<) instead of pipes for all grep checks. 2. Incomplete LIB_FUNS: hand-maintained REQUIRED_LIBS list (11 files) didn't cover all 26 lib/*.sh files, silently producing a partial function list. Fixed by enumerating all lib/*.sh in stable lexicographic order (LC_ALL=C sort), excluding only standalone scripts (ci-debug.sh, parse-deps.sh).
