Unsorted TODO list of features and points of investigation that could be
|
|
useful for improving finit. But what is an improvement to finit? Well,
|
|
similiar to launchd, the goal of finit is to be a FAST replacement for:
|
|
|
|
* init
|
|
* inetd
|
|
* crond
|
|
* watchdogd
|
|
|
|
The main goal is to be FAST. Secondary goals are to be: small, simple
|
|
and with a very low dependency to external packages.
|
|
|
|
Priority
|
|
--------
|
|
The intent of finit is to monitor not just processes, but also to
|
|
be able to supervise the entire system and the behavior of certain
|
|
processes that declare themselves to be finit compliant.
|
|
|
|
* Integrate the ingenious libev to handle all events: signals,
|
|
polling fd's, etc. Because "Event driven software improves
|
|
concurrency" -- Dave Zarzycki, Apple. See the launchd video
|
|
at http://www.youtube.com/watch?v=cD_s6Fjdri8 for more info!
|
|
* Add support for process and system supervision. Which could
|
|
be an API wrapping, e.g., TIPC and loadavg.
|
|
* Add support for a /dev/watchdog plugin to replace watchdogd
|
|
* Integrate watchdog plugin with process/system supervisor to
|
|
reboot the system when a process stops responding, or when
|
|
restarting it is imposible, as well as when system load gets
|
|
too high.
|
|
|
|
Configuration
|
|
-------------
|
|
* Add support for "init <q | reload-configuration>" and SIGHUP to
|
|
reload finit.conf, but also
|
|
* Add support for inotify to automatically reload finit.conf
|
|
|
|
Runlevels
|
|
---------
|
|
* Add support for "runlevel N" to finit.conf
|
|
* Improve support for runlevels: startup, running (services from
|
|
finit.conf), and shutdown as well as hooks when switching RL,
|
|
startup at RL 1 and a default run level.
|
|
* Implement initctl stop|start|restart|reload|status <SVC> and
|
|
service <SVC> stop|start|restart|reload|status on top
|
|
* Add PRE and POST hooks for when changing runlevels
|
|
* SysV init in Debian uses an rcS.d/ for scripts that should run once
|
|
at boot. These scripts are run before the actual runlevel set in
|
|
inittab. In finit we could use "task [S]" and "boot [S]" for this.
|
|
* Add support for a new runlevel 'S' that is started before all other
|
|
services in the selected runlevel.
|
|
|
|
Services and Tasks
|
|
------------------
|
|
Both the "task" and "boot" stanzas below are like "service", share the
|
|
same mechanism for registering callbacks. These callbacks can be used
|
|
to check a configuration db and return 1 (RUN), 2 (STOP), or 3 (RELOAD).
|
|
|
|
* Add support for "task [RUNLVL] ..." similar to services, but
|
|
one-shot. Needs a trigger/when
|
|
* Add support for "boot [RUNLVL] ..." similar to services, but
|
|
waits for completion before continuing with the next line
|
|
* Add support for service/task dependencies
|
|
* Add support for "init list" to show running services
|
|
|
|
Miscellaneous
|
|
-------------
|
|
* Add support for "init -v,--version | version"
|
|
* Cleanup move sources from top-level directory to src/ and include/
|
|
* Make sure to install queue.h to $(PREFIX)/include/finit/queue.h
|
|
|
|
Documentation
|
|
-------------
|
|
* Write man pages for finit and finit.conf, steal from pimd man pages...
|
|
* Update Debian finit.conf example with runlevels, tty/console and
|
|
dependency handling
|
|
|
|
Investigation
|
|
-------------
|
|
* FHS changes affecting runtime status, plugins, etc., see
