From 1f720ac2dd7aa20a5441fef9df5935c20ac1d30a Mon Sep 17 00:00:00 2001 From: dongshengyuan <545258830@qq.com> Date: Tue, 30 Jun 2026 18:10:49 +0800 Subject: [PATCH] coredumpctl: use break instead of continue for time bound checks When iterating journal entries with --until (forward scan) or --since (reverse scan), the code used continue instead of break after crossing the time boundary. Since sd_journal_seek_realtime_usec() is called before the loop to position at the start of the range, sd_journal_next()/previous() returns entries in monotonically increasing/decreasing time order. Once an entry's timestamp exceeds arg_until (or falls below arg_since in reverse), all subsequent entries will also be out of range. Using continue caused the entire remaining journal to be scanned unnecessarily. journalctl uses break for the identical pattern in src/journal/journalctl-show.c.
