Due to time constraints I had to revert the new libev backend to the
service, I/O and signals monitor. Employed instead is the tried and
tested signals based service monitor, with a small extension for an
additional I/O monitor using poll() for the I/O plugins to use.
Tried restoring the startx finit.conf directive on top of the service
implementation. However, it's currently not usable to run /usr/bin/startx
for any other user than root. I recommend using the examples/finit.conf
and run /usr/sbin/gdm instead.
finit.c:
New run_loop() function, replaces libev ev_run().
helpers.c:
Refactor start_process() into svc_start().
plugin.c:
Add fds[] array for use in the io_monitor() called by the
new run_loop().
signal.c:
Ignore SIGCHLD. Handled by waitpid() in svc_monitor() now,
which is called by the new run_loop().
svc.c:
svc_register(): Optional @username parsing for the command line.
svc_monitor(): Replaced libev callback with waitpid()
svc_start(): Refactored to use most of helpers.c:start_process()
