--------------------------------------------------------------------------------
- define service status in one document, so repeatition stops!
--------------------------------------------------------------------------------
- add error handling to cinit.install.binary
--------------------------------------------------------------------------------
- add code do implement stopping / restarting with dependency tree
--------------------------------------------------------------------------------
# cinit.create.empty.service: can only be started from the bin directory
- Fix Switching services off !!
- Error codes when shutting down a service?
- Delay dokumentieren
- no_kill dokumentieren
- on.out, on.err, on.in?
-> reading/writing from/to files
- implement "no_kill" until cinit-0.2 or 0.3?
--------------------------------------------------------------------------------
- Source Logic issues
- remove FIXME entries (and what should be fixed, too)
--------------------------------------------------------------------------------
Helper scripts, rausgenommen aus Der Doku, muessen fuer
cinit-0.3 ueberprueft werden:
Configure help scripts
~~~~~~~~~~~~~~~~~~~~~~
cinit-conf later
Using prepared scripts
In the bin/ directory of this tarball you'll find at least:
cinit.add.dependency - add a dependency to a service
cinit.add.getty - add a new getty
cinit.create.empty.service - create an empty service
cinit.reboot - reboot in /bin/sh
cinit.remove.getty - remove a getty service
cinit.respawn.off - switch respawing off
cinit.respawn.on - switch respawing on
cinit.shutdown - shutdown in /bin/sh
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
Optimisations
-------------
- Installing cinit
o compiling cinit from source
o debian / gentoo
- Configuring
* add scripts! see below
- define coding guidelines -> general, with url?
- Write manpages (use doc/* as base for that)
- Check Spell and Grammar in documentation
- write howto:
o Howto-cinit
o Howto-cinit-uml
tree_exec
~~~~~~~~~
- only check dependencies (=needs) after the basic run?
Documentation
-------------
developer
~~~~~~~~~
- ST_IN_LIST == startup marker, used to (NOT) insert services into startup
- dep_needs_wants_add is used to add dependencies of a service to the general
starter list
user
----
- do we really need swapoff? remove umount, swapoff!
* to services!
-> they have to do it!
- dependencies with leading '.' (dot) are ignored.
- about cinit-configuration structure
* cconfig
* svc/
* special/ (or however we called it)
- panic
- halt
- poweroff
- reboot
--------------------------------------------------------------------------------
FAQ
~~~
- DOKU: what happens when a service does not terminate....
und er als once drin ist
--> Wenn kein ReSPAWN und der Prozess beendet sich nicht,
dann haengt init!
- multuicall probleme -> busysbox --> GIBT ES NICHT!!
---> DOKU DAZU! mit links, doppelt links, aus test
---> erklaeren, dass es unproblematisch ist!
--------------------------------------------------------------------------------
csvc:
11:09 < folken23> telmich: oder service allready started.
--------------------------------------------------------------------------------
cinit:
11:09 < folken23> telmich: zsb. eine grund angabe warum ein dienst nicht gestartet
werden konnte.
11:09 < folken23> telmich: e.g. file nicht gefunden, service hat nicht 0
zurueckgeworfen.
---> errno in execute_sth!
Child handlin
~~~~~~~~~~~~~g
- free() everything before starting child
Later
~~~~~
- close(*>2) before forking / executing
-> close fds, clean environment, etc., ...
-> do we really need that?
-> yep, clean environment!
- logging service!
-> write output $somewhere, wait for syslog?
-> flush at the end of start-process?
-> perhaps pipe logging output to a program?
--------------------------------------------------------------------------------
- Doc
* main.text -> cleanup / remove / split
* config-dirs
* FAQ
* ideas
* meta.dependencies
- config/hints/meta depps
* optimising
- integrate into other
* README.text
- update
* replacing.init
- update / integrate
* special-services.text
- into configuring/hints?
* TODO
- into paths, if necessary
* updating.cinit
- update as soon as update is possible?
* using.rescue
- update as soon as update is possible?
* 'os-integration.text'
* 'daemons.backgrounding'
* There are some hints on how to migrate to cinit in general and also
some os specific help in the file 'migrating-init-systems.text',
- CODECHECK:
* what happens with the wants of the last services?
- are they added?
- are they added at the correct position?
- scripts
* `cinit.check.config` (doc/user/configuring.cinit.text)
-> circular depedencies!
- Doc.next:
- installing: report!
-> write report script.
- Doc later
* current-init-problems.text
- current-init-problems.text explains why cinit does not use nor recommends the use of shell scripts.
* special-services.text
- Begin documentation
* Check Makefile
* Integrate Makefile into main Makefile
* create manpage
* Write a small manual
- install
- configure
- boot (different OS)
* generate asciidoc!
- Doc way:
* installing
* configuring
- testconfig!
* booting
- different OS / bootloader
* debugging
- Shutdomn code:
* begin at init, then shutdown wants/needs, ...
- check that the new wants and need elements are nserted the other way round
* we go to next, elements must be put before us!
- replace cinit_ipc_logon with cinit_ipc_init...
* delay ipc code -> after start!
- Cleanup / create object lists
object-lists/
cinit
cservice
ccontrol
cinit.halt
cinit.reboot
cinit.shutdown (shell script?!?)

There is no GIT repository here (.git not found)
make: *** [sizecheck] Fehler 1
- setup VM for testing: qemu/kvm/virtualbox (no commercial bloaty)
-> uml!
- sleep when respawnig!
-> static delay of five seconds
do_reboot.c:
is ipc closed? -> check! => done!
- ignore msgrcv: Interrupted system call
Session terminated, killing shell...msgq-destroy: Invalid argument
msgq-destroy: Invalid argument
- do not print an error if /etc/cinit/conf/last is non-existent!
=> print it. Do not not print it, as this can aid debugging.
include locking via shm, remove test on pid1
=> not necessary imho currently
TODO.pre10:
Done:
cleanup client/ comm/ contrib+tools/ util/ tmp/
Debugging cinit-configuration:
ls -lR /etc/cinit
or: cinit.read....
TODO.pre11:
Remove some debugging, re-introduce DEBUG() macro..
Fix doc:
make dist should cleanup cc / ld to sane values?
or do I experiement in tmp/*?
http://linux.schottelius.org/cinit/browse_source/current/doc/user/config-dirs
conf/c_halt
IPC:
* check msqg-code
* documentate the ipc functions: update devel/ipc.text
* check cinit_read_command() (devel/ipc.h)
do_reboot.c:
write cinit_svc_shutdown
- implement do_reboot()
* so not only booting with cinit works, but also the shutdown
- write libcinit for use in cmd()
- find out why gettimeofday() and time() do strange things when called in SIG_CHLD
=> bug opened in glibc, got to code testprogram
- write cinit.conf.check
* report broken links in needs/wants
* report circular dependencies
- pretty print, reporting is ugly!
Add handler for ctrl+alt+delete
* document in paths
* check whether there's an os-unspecific way to do that
cleanup bin/
- write sys-v-init-shutdown-wrapper
* shutdown
* halt
* reboot
* poweroff
- write manpages for
- *.kill
- cmd
install:
make install => does not overwrite critical targets
* cinit
* *.kill (see client/*)
* cmd
make force-install => overwrites /sbin/{halt,poweroff,reboot}?
=> with script that wraps cmd
make install-template:
* creates categories
make install-miniconf:
* creates categories
* creates one service starting a shell (depending on the OS!)
cleanup src/
finish ipc code so clients can access cinit
implement CMD_INFO (see comm.h)
TODO.pre12:
Check and clean doc/
Remove *TODO*+ROADMAP and leave behin doc/TODO
TODO.pre13:
code cmd=(cservice ccontrol halt reboot shutdown poweroff)
=> halt/r/... also with kill ...
Test, release and prepare for final cinit-0.3
TODO.0.3.1
add log support
cinit logs to
-> shm saver
services log to
TODO unclear
- create migration scripts
