otherwise /run/openrc might not exist, and result on svcdirfd being -1

only one consumer, checkpath, and can easily be done directly with the
access syscall
|
|
the exists() helper uses stat.2 unnecessarily, while calling access is
simpler and does not require filling a struct stat for no reason.
since this would make exists() into a wrapper that calls a single
function and nothing else, let's just inline the calls to access and
remove the helper.

|
Make it consistent with the other one: in case of error report failed
input.
Also change quoting from `%s' to '%s'.

to specify a different host, meson's machine files should be used
instead.

with this we can define `notify=socket` as an overall systemd
"notify-socket" compatibility flag. in the future, `nofiy=socket` will
simply enable access to the basic STATUS= command, `socket:ready`
enables READY=1, `socket:fdstore` would enable fd-store compat,
`socket:watchdog:<timeout>` for the watchdog and so on.
the format of the variable would end up being:
`notify="protocol[:option[,option ...]]"`

openrc-run can be called from places that don't reset the signal mask
before exec, example being the pam close_session session hook called
from runuser, which leads to svc_exec hanging, as SIGCHLD is never
delivered.

avoids wasting resources by spamming restarts on a service which
would've failed anyways.
|
|
allows specifying increasing respawn delay. for example, to try
respawn immediately at first and then slowly backing off if the
service continues to keep failing within respawn-period to avoid
misusing system resource on trying to keep restarting a bad
service too fast.

it makes no sense for the parent to hold the lock, even with cloexec,
and that makes attempts to wait on flock useless. it only worked so far
due to busy-polling with open, so basically, we were waiting for an
unlink, not a lockfile.

this also fixes the behaviour of rc_service_scheduled_by, returning
a stringlist of service names, instead of the script that is being
scheduled.

readiness notification is experimental, and imo naming it 'ready' was a
mistake, most other projects call them notify-fd, notify-socket, etc
systemd's protocol in particular, we plan to support a few more keys
than just "READY=1" (namely "STATUS" to begin with), so 'notify' is a
better variable name in my view

snprintf return value does not include the nul-byte, so return
of `== size` is also a truncation case.

the goal is to provide a safe and easy string building api for
new code and to replace some of the old code doing error prone,
ad-hoc coded and manual string building at the moment.

instead, move caches to /var/cache/openrc. If /var is not mounted, cache
will not be used and the deptree would be regenerated
user services use ${XDG_CACHE_HOME}/rc, defaulting to ~/.cache

based on the systemd notify socket protocol, although at the moment we
only support READY=1.

a few matches were not typos (e.g. ahd), or not changes i'd care to make (e.g.
bootup vs boot up).

avoids assuming argv[0] is the command
|
|
|
|
more suitable here since this is exec related and not
necessarily plugin related.
|
|
since rc_exec uses an `execpipe` to detect exec failures inside
the child, this fixes the issue described in 792, but only for
the first layer of exec. there's a /bin/sh in the middle and we
won't be able to detect whether /bin/sh failed to exec the
command without inspecting the (unreliable) exit code.

currently there's a lot of ad-hoc fork exec going around. the
goal of this is to centralize most of the typical cases.

it's generally advisable to use `_exit` rather than `exit` from
forked child to avoid triggering things like `atexit` handlers
and whatnot.

The syscall expects unsigned integers.

Adds two helper functions, and allows scripts to wait until services are
ready before proceeding with it's dependees by setting `ready=fd:<num>`,
where <num> is the file descriptor the daemon should write a new line to.
