-------------------
None.
OPTIONAL PARAMETERS
-------------------
state::
'present' or 'absent', defaults to 'present'
EXAMPLES

__typename /foo//bar//baz # // will be converted to / implicitly through fs; error prone; disallow

Solution:
1) allow require __a//b: type __a, object id /b
=> strip first slash of object id, as we do in non-dep-mode
2) allow _one_ trailing /: __type /foo/bar/ and require="__foo/abc/"
=> strip one leading slash of object id
3) disallow // within object id

- parameter/setting default from manifest
==> BRANCH[feature_default_parameters],
==> PERSON[Steven or Nico]
==> PROPOSAL(1)
- current bug
- proposal 1: parameter/default/$name (for optional ones)
- new way
- catches --state absent|present
- needs changes of types
- also possible for explorer
- support for it in core?
- handling of ${o} $o "$o" ?
- handling which variables?
- introduction of "templating language"
- aka macros
- possible problems:
- inconsistency
- redoing shell functionality
- raising expectations for more templating from users
- possible benefit
- no need for eval
- once in core, not everytime in type
- OTOH: one extra word.
- a=$(cat $__object/parameter/name) vs. $(eval $(cat $__object/parameter/name))
- only possible for static defaults
- --name overrides name not possible vs. object_id
- Is this the only case????
- if yes: don't care.
- possible solution:
- echo '/$__object_id' > typename/parameter/default/name
- eval $(cat $__object/parameter/name)
- probably allows code injection
- is possible anyway???
- $(cat /etc/shadow)
- other eval side effects???
- none: go for it
- some: have headache
- many: don't do
- proposal 2: 2 dbs (user input vs. stuff changable by type)
- explicit 2nd db [parameter_user and parameter/]
- not very clean (both agreed)
- proposal 3: parameter are read-only
- breaks current types (in core probably elsewhere)
- can't enforce, but user is on his own => breaks, her problem
+ clean seperation between core and type (nico)
- parameter belongs to type not core (steven)
- proposal 4: core ignores changes in parameter/* of object
- implicit 2nd db [see automagic below]
- steven+++
- does not work with divergent emulator not being in core
- because emulators primary db __is__ fs.
1 manifest:
__foo bar == emulator
echo present > $__global/object/__foo/bar/parameter/state
# fails
__foo bar == emulator
! automagic / filesystem
! fsproperty:
- kill, write explicitly to disk
==> BRANCH[cleanup_fsproperty]
==> PERSON[Steven]
==> PROPOSAL(just cleanup)
- implicit/automatic writes/read to fs
- explicit interfaces are better then implicit
- same problems as in cdist 1.x to 2.x move! (environment!)
- format on disk should not change/dictate code flow
- degrade python to shell (nico++! steven--)
- user should not care about python, ruby, .net or ASM implementation (steven++ nico++)
? proposal 1: diverge emulator / core
- emulator verifies input
- emulator writes to fs
- core reads/syncs from/to fs before passing control to user
? proposal 2: emulator is dumb and passes data to core
- core creates objects
- no fs involved
- core reads/syncs from/to fs before passing control to user
- passing:
- full objects via pickle
- parameters only
- how???
- unix socket?
- not everywhere possible?
- tcp / ip
- not everywhere possible
- chroot / local only
- rfc 1149
- not everywhere possible
- missing avian carriers
- 0mq
- not everywhere possible
- not installed
- shm (ipcs and friends)
- not everywhere possible
- no /dev/shm, different libraries? cleanups needed...
- what speaks against FS?
- emulator_input/.../
- nico: to fancy probably
! boolean implementation
==> BRANCH[feature_boolean_parameter]
==> PERSON[Steven]
- nico:
- parameters/boolean: document
- argparse changes (consider parameters/boolean)
- create
- can be implemented with changes in emulator
- use store_true, del if false => never seen by core
- INDEPENDENT INDEPENDT OF FS.PROPERTIES!!111111!
- emulator:
- how much integrated into core
- also: using CdistObject????
- dependency on filesystem: good (nico) | bad (steven)
- singleton / support without object_id
- not discussed
- __apt_ppa:
==> BRANCH[bugfix_do_not_change_state_in_manifest]
==> PERSON[Nico]
- logging divergent between emulator / core
- no problem (nico)
- may be helpful (steven)

HOW TO SUBMIT A NEW TYPE
------------------------
For detailled information about types, see cdist-type(7).
Submitting a type works as described above, with the additional requirement
that a corresponding manpage named man.text in asciidoc format with
the manpage-name "cdist-type__NAME" is included in the type directory
AND asciidoc is able to compile it (i.e. do NOT have to many "=" in the second
line).
Warning: Submitting "exec" or "run" types that simply echo their parameter in
gencode* will not be accepted, because they are of no use. Every type can output
code and thus such a type introduces redundant functionality that is given by
core cdist already.

@ -72,15 +72,42 @@ To begin a new type, just create the directory **conf/type/__NAME**.
DEFINING PARAMETERS
-------------------
Every type consists of optional and required parameters, which must
be created in a newline seperated file in ***parameters/required*** and
***parameters/optional***. If either or both missing, the type will have
no required, no optional or no parameters at all.
Every type consists of required, optional and boolean parameters, which must
be created in a newline seperated file in ***parameter/required***,
***parameter/optional*** and ***parameter/boolean***. If either is missing,
the type will have no required, no optional, no boolean or no parameters at
all.
Example:
--------------------------------------------------------------------------------
echo servername >> conf/type/__nginx_vhost/parameter/required
echo logdirectory >> conf/type/__nginx_vhost/parameter/optional
echo use_ssl >> conf/type/__nginx_vhost/parameter/boolean
--------------------------------------------------------------------------------
USING PARAMETERS
----------------
The parameters given to a type can be accessed and used in all type scripts
(e.g manifest, gencode-*, explorer/*). Note that boolean parameters are
represented by file existence. File exists -> True,
file does not exist -> False
Example: (e.g. in conf/type/__nginx_vhost/manifest)
--------------------------------------------------------------------------------
# required parameter
servername="$(cat "$__object/parameter/servername")"
# optional parameter
if [ -f "$__object/parameter/logdirectory" ]; then
logdirectory="$(cat "$__object/parameter/logdirectory")"
fi
# boolean parameter
if [ -f "$__object/parameter/use_ssl" ]; then
# file exists -> True
# do some fancy ssl stuff
fi
