From ccc2c98e1b0c06861577632440b996ca16cefd53 Mon Sep 17 00:00:00 2001 From: Lukáš Nykrýn Date: Sat, 16 Jul 2016 21:04:13 +0200 Subject: manager: don't skip sigchld handler for main and control pid for services (#3738) During stop when service has one "regular" pid one main pid and one control pid and the sighld for the regular one is processed first the unit_tidy_watch_pids will skip the main and control pid and does not remove them from u->pids(). But then we skip the sigchld event because we already did one in the iteration and there are two pids in u->pids. v2: Use general unit_main_pid() and unit_control_pid() instead of reaching directly to service structure. --- src/core/manager.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/src/core/manager.c b/src/core/manager.c index 902c2a0a27..c69b797430 100644 --- a/src/core/manager.c +++ b/src/core/manager.c @@ -1729,7 +1729,10 @@ static void invoke_sigchld_event(Manager *m, Unit *u, const siginfo_t *si) { unit_unwatch_pid(u, si->si_pid); if (UNIT_VTABLE(u)->sigchld_event) { - if (set_size(u->pids) <= 1 || iteration != u->sigchldgen) { + if (set_size(u->pids) <= 1 || + iteration != u->sigchldgen || + unit_main_pid(u) == si->si_pid || + unit_control_pid(u) == si->si_pid) { UNIT_VTABLE(u)->sigchld_event(u, si->si_pid, si->si_code, si->si_status); u->sigchldgen = iteration; } else -- cgit v1.2.3-54-g00ecf
