Package: apache
Version: 1.3.31-6
While upgrading apache in a chroot, I noticed that:
(a) there are two lines trying to stop apache, and not one:
Preparing to replace apache 1.3.31-3 (using .../apache_1.3.31-6_i386.deb) ...
Stopping web server: apache.
Stopping web server: apacheNo process in pidfile `/var/run/apache.pid' found
running; none killed.
.
This might be a different issue, and fwiw, I don't consider the mere fact that
two lines are displayed a bug worth reporting.
(b) It killed the apache process that was running on the main system in addition
to the one in the chroot. The init.d script should _not_ touch random
processes called 'apache', but only those that are part of the apache package.
The prerm kills all `pidof apache`, it could at least use `pidof
/usr/bin/apache to limit it to processes that are Debian's apache (this will
not fix killing of apache in other/parent chroot's, but is still better).
pidof(8):
| When pidof is invoked with a full pathname to the program it should
| find the pid of, it is reasonably safe. Otherwise it is possible
| that it returns pids of running programs that happen to have the same
| name as the program you're after but are actually other programs.
In order to really fix killing of processes in different chroots, you could
check whether /proc/$PID/exe is a symlink to '/usr/bin/apache' (and doesn't
give an error). For chroots that are below the root of the current process,
that will give /chroot/usr/bin/apache (for example), and for roots that are
upwards of the current root, it will give a permission denied.
Thanks,
