This is needed in preparation for adding support for a fifo to allow us
to communicate with the supervisor to ask it to signal the child it is
supervising.
This reverts commit 2af0cedd59.
After speaking with Luis Ressel on the Gentoo selinux team, I am reverting
this commit for the following reasons:
- Luis told me that he feels this is not the solution we need to address
the concern with checkpath; I will be working with him on another
solution.
- There are concerns about the way the path variable was handled
and the assert() call.
The path variable should be dynamically allocated using xasprintf
instead of defining a length at compile time. This would eliminate the
need for the assert() call.
- It introduces the definition of _GNU_SOURCE which makes it
easier to introduce portability concerns in the future (see #262).
The pidfile of the supervisor doesn't need to be adjustable by the
service script. It is only used so the supervisor can stop itself when
the --stop option is used.
In start-stop-daemon and rc-schedules, we were printing out a warning if
the nanosleep call was interrupted by a signal, but we did not treat
this as an error situation other than displaying the message, so there
is no need for the message.
Health checks are a way to monitor a service and make sure it stays
healthy.
If a service is not healthy, it will be automatically restarted after
running the unhealthy() function to clean up.
You can now schedule a shutdown for a certain time or a cpecific number
of minutes into the future.
When a shutdown is running, you can now cancel it with ^c from the
keyboard or by running "openrc-shutdown -c" from another shell.
Fix the comparison between respawn_count and respawn_max so that
respawn_max = 1 will allow for one respawn. Since respawn_count is
incremented before the comparison, use a 'greater than' comparison
so that respawn will be triggered when respawn_count is equal to
respawn_max.

This fixes#237
This test to find if we could see pid 1 was being used inconsistently in
rc-status and mark_service_crashed to decide whether we could test to
see if the daemon for the service was crashed, and it was not part of
the librc library.
I am removing it from the executables because of inconsistent usage. I
will add it to the library if it is needed there.
If pidfile does not exist when we are stopping the daemon, assume it is
already stopped, and report success.
hostapd is an example of a daemon which removes its pidfile when it is
exiting. If this daemon terminates prematurely, that is, without s-s-d
involvement, then openrc fails to restart it, because s-s-d "stop"
command fails when pidfile is missing.

This is our own version of asprintf(). This original code was written by
Mike Frysinger, and I was able to modify it to use our memory helper
functions.
We need a version of this code because it is not available on glibc at
least without defining _GNU_SOURCE, and I would rather not do that.
This is the first step in improving string handling in OpenRC for #207.
This is related to #195.
This is an attempt to shorten the window for the first two issues
discussed by using a file descriptor which does not follow symbolic
links and using the fchmod and fchown calls instead of chown and chmod.
with.
rc_deptree_update_needed would return early as soon as it found
any file newer than the existing dependency cache. Unfortunately,
the first file found may not be the newest one there; so the
clock skew workaround in rc-misc:_rc_deptree_load would be given
a timestamp that was still too old.
This fix forces a full scan of all relevant files, so as to
ensure that we return a timestamp that will allow the clock skew
fix to operate. The runtime cost is no worse than the case where
the cache is up to date (ie. we must check every possible file).
This fixes#161.
Ignore namespaces if there are errors reading either the pid namespace
for the current process or the process we aare testing.
