Zbigniew Jędrzejewski-Szmek a9becdd65b sd-daemon,man: ignore missing $WATCHDOG_PID ... Systemd 209 started setting $WATCHDOG_PID, and sd-daemon watch was modified to check for this variable. This means that sd_watchdog_enabled() stopped working with previous versions of systemd. But sd-event is a public library and API and we must keep it working even when a program compiled with a newer version of the libary is used on a system running an older version of the manager. getenv() and unsetenv() are fairly expensive calls, so optimize sd_watchdog_enabled() by not calling them when unnecessary. man: centralize the description of $WATCHDOG_PID and $WATCHDOG_USEC in the sd_watchdog_enabled manpage. It is better not to repeat the same stuff in two places.		2014-10-23 00:17:18 -04:00
