Package: dash Version: 0.5.7-4+b1 Severity: normal Control: affects -1 mysql-server-5.5
The wait builtin apparently returns immediately upon SIGCHLD, which means it will return prematurely if a child is stopped or continued: set +m sleep 1000 & wait # This will return immediately if SIGSTOP is sent to the sleep process wait # This will return immediately if SIGCONT is sent to the sleep process This "cmd & wait" pattern notably appears in the Debian version of mysqld_safe (as a fix for #527623). Combined with a VPS that throttles CPU usage via SIGSTOP/SIGCONT, this resulted in lots of hair-pulling on my part. -- System Information: Debian Release: 8.0 APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (x86_64) Foreign Architectures: amd64 Kernel: Linux 3.16.0-4-amd64 (SMP w/3 CPU cores) Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages dash depends on: ii debianutils 4.4+b1 ii dpkg 1.17.25 ii libc6 2.19-17 dash recommends no packages. dash suggests no packages. -- debconf information excluded -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
