Allows redirecting process stdin and stdout to another process,
just like is already possible with start-stop-daemon.
Also added --stdout-logger and --stderr-logger to the man page.

If supervise_daemon_args is not set *or empty*, it defaults to
`start_stop_daemon_args`. This is bad because supervise-daemon doesn't
accept the same options as `start-stop-daemon`. So if we set e.g.
`start_stop_daemon_args="--wait 50"`, but not `supervise_daemon_args`,
and the user adds `supervisor=supervise-daemon` to the corresponding
/etc/conf.d/<service> file, the service will fail to start due to
unrecognized option "wait".
It would be best to remove this fallback, but that might break some
existing scripts that depend on it. So this commit just changes it to
use `start_stop_daemon_args` as the default for `supervise_daemon_args`
only if `supervise_daemon_args` is not set at all, but not if it's
empty.
This at least simplifies workarounds; we can just add
`supervise_daemon_args="$supervise_daemon_args"` to init scripts.
This fixes #558.

This add No New Privs flag for start-stop-daemon and supervise-daemon
by adding --no-new-privs flag. As a result, the user set the No New
Privs flag for the program should run with.

This adds securebits flags for start-stop-daemon and supervise-daemon
by adding --secbits option. As a result, the user can specify
securebits the program should run with. see capabilities(7)
|

This adds capabilities for start-stop-daemon by adding --capabilities
option. As a result, the user can specify the inheritable, ambient and
bounding set by define capabilities in the service script.
This fixes #314.

This makes the URIs shorter and dynamic: whatever the default branch
the repo uses will be used.

Since the pid file is internal to us, start moving toward deprecating it
by not requiring the user to specify it.
In the next release, I plan on working on code to start phasing out the
use of a pid file if this is possible.
|
|
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.

This fixes #230.

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.

Add the following variables to expose more arguments that can be passed
to start-stop-daemon or supervise-daemon:
- directory will be passed to --chdir
- error_log will be passed to --stderr
- output_log will be passed to --stdout
- umask will be passed to umask
This is for #184.

This makes ps show which service the supervisor is monitoring.
|
|
The unsupervised status is to be used when a supervisor of a supervised
service dies but leaves the service daemon itself running.
|
|
|
|
This is to be used if the service is being supervised and the
supervisor is somehow killed.
Currently, this is very linux specific, but I will expand to other
platforms, patches are welcome.

The --retry option for supervise-daemon defines how the supervisor will
attempt to stop the child process it is monitoring. It is defined when
the supervisor is started since stopping the supervisor just sends a
signal to the active supervisor.
This fixes #160.

This creates --respawn-delay, --respawn-max and --respawn-period. It was
suggested that it would be easier to follow if the options were
separated.
This is for #126.
|
|
Allow limiting the number of times supervise-daemon will attempt to respawn a
daemon once it has died to prevent infinite respawning. Also, set a
reasonable default limit (10 times in a 5 second period).
This is for issue #126.

This reverts commit 0d1f1010c299a95332f224c3be9e8dfdd85eec54.
We need the eval in case someone uses something like:
command_args="this \"is a\" test"
This is related to #77.

This fixes #77.
|

This fixes #79.

|
The supervise-daemon process is meant to be a lightweight supervisor
which can monitor and restart a daemon if it crashes.
