From 857f047e40f796aa43c6e7c754d8a32ee64e4f4d Mon Sep 17 00:00:00 2001 From: Adrian Ratiu Date: Fri, 26 Dec 2025 14:23:30 +0200 Subject: hook: allow overriding the ungroup option When calling run_process_parallel() in run_hooks_opt(), the ungroup option is currently hardcoded to .ungroup = 1. This causes problems when ungrouping should be disabled, for example when sideband-reading collated output from child hooks, because sideband-reading and ungrouping are mutually exclusive. Thus a new hook.h option is added to allow overriding. The existing ungroup=1 behavior is preserved in the run_hooks() API and the "hook run" command. We could modify these to take an option if necessary, so I added two code comments there.
