From d0a0b352e0dd5003a380563190a8b9de0a22e263 Mon Sep 17 00:00:00 2001 From: Alex Date: Thu, 17 Sep 2026 13:03:59 +0100 Subject: [PATCH] fix: drop the host-substring assertions and explain the empty except CodeQL flags `"host:port" in message` as incomplete URL sanitisation. It is a message rather than a URL being authorised, so it is not a vulnerability, but the check was red and comparing against the sanitiser's own output asserts the real contract. The signal handler now says why it swallows: the child is already gone, and shutdown must not fail on what it is cleaning up. --- docsgpt/deploy/dev.py | 2 ++ tests/deploy/test_doctor.py | 9 ++++++--- 2 files changed, 8 insertions(+), 3 deletions(-) diff --git a/docsgpt/deploy/dev.py b/docsgpt/deploy/dev.py index a49dcf07..a552646e 100644 --- a/docsgpt/deploy/dev.py +++ b/docsgpt/deploy/dev.py @@ -143,6 +143,8 @@ def _signal(process, number: int) -> None: return os.killpg(os.getpgid(process.pid), number) except (ProcessLookupError, PermissionError, OSError): + # The child has already gone, or its group is no longer ours to signal.
