From: Hoyoung Lee Date: Tue, 22 Jul 2025 07:36:34 GMT Subject: [PATCH 4/4] t/helper/test-delta: close fd if fstat() fails after second open() Message-ID: <20250722073634.1080217-5-lhywkd22@gmail.com> In-Reply-To: <20250722073634.1080217-1-lhywkd22@gmail.com> When opening argv[3], if open() succeeds but fstat() fails, the file descriptor is not closed, resulting in a resource leak. This patch ensures that the descriptor is closed on failure.
