masqmail
annotate man/mservdetect.8 @ 72:ad034b57f3b2
fixed Debian bug 536060 (log files are closed after SIGHUP receival)
Explanation:
When run in daemon mode, first the log files are opened. They get
assigned to the file descriptors 3 and 4 usually. Then std{in,out,err}
are closed. When SIGHUP comes in, all open files are closes and
masqmail reexecutes itself. The new masqmail instance opens the log
files at fd 0 and 1 now, but std{in,out,err} are closed afterwards,
thus the log files are closed.
The fix is to close the log files before std{in,out,err} are closed,
in case the log files have higher fds. After std{in,out,err} were
closed, the log files get opened again, now.
