this simplifies consume_vendordata a bit, changes consume_vendordata to
be by default "PER_INSTANCE" (like userdata).
The other thing we do here is move the exlusion to be handled when walking the
data. The benefit of doing it then is that we can exclude part-handlers.
Without the ability to exlude part handlers, exclusion is basically useless
(since part-handlers could accomplish anything they wanted).

vendordata.
Vendordata is a datasource provided userdata-like blob that is parsed
similiarly to userdata, execept at the user's pleasure.
cloudinit/config/cc_scripts_vendor.py: added vendor script cloud config
cloudinit/config/cc_vendor_scripts_per_boot.py: added vendor per boot
cloud config
cloudinit/config/cc_vendor_scripts_per_instance.py: added vendor per
instance vendor cloud config
cloudinit/config/cc_vendor_scripts_per_once.py: added per once vendor
cloud config script

(RENAMED) tests/unittests/test_userdata.py => tests/unittests/test_userdata.py
TO: tests/unittests/test_userdata.py => tests/unittests/test_data.py:
userdata test cases are not expanded to confirm superiority over vendor
data.
bin/cloud-init: change instances of 'consume_userdata' to 'consume_data'
cloudinit/handlers/cloud_config.py: Added vendor script handling to default
cloud-config modules
cloudinit/handlers/shell_script.py: Added ability to change the path key to
support vendor provided 'vendor-scripts'. Defaults to 'script'.
cloudinit/helpers.py:
- Changed ConfigMerger to include handling of vendordata.
- Changed helpers to include paths for vendordata.
cloudinit/sources/__init__.py: Added functions for helping vendordata
- get_vendordata_raw(): returns vendordata unprocessed
- get_vendordata(): returns vendordata through userdata processor
- has_vendordata(): indicator if vendordata is present
- consume_vendordata(): datasource directive for indicating explict
user approval of vendordata consumption. Defaults to 'false'
cloudinit/stages.py: Re-jiggered for handling of vendordata
- _initial_subdirs(): added vendor script definition
- update(): added self._store_vendordata()
- [ADDED] _store_vendordata(): store vendordata
- _get_default_handlers(): modified to allow for filtering
which handlers will run against vendordata
- [ADDED] _do_handlers(): moved logic from consume_userdata
to _do_handlers(). This allows _consume_vendordata() and
_consume_userdata() to use the same code path.
- [RENAMED] consume_userdata() to _consume_userdata()
- [ADDED] _consume_vendordata() for handling vendordata
- run after userdata to get user cloud-config
- uses ConfigMerger to get the configuration from the
instance perspective about whether or not to use
vendordata
- [ADDED] consume_data() to call _consume_{user,vendor}data
cloudinit/util.py:
- [ADDED] get_nested_option_as_list() used by cc_vendor* for
getting a nested value from a dict and returned as a list
- runparts(): added 'exe_prefix' for running exe with a prefix,
used by cc_vendor*
config/cloud.cfg: Added vendor script execution as default
tests/unittests/test_runs/test_merge_run.py: changed consume_userdata() to
consume_data()
tests/unittests/test_runs/test_simple_run.py: changed consume_userdata() to
consume_data()

Fix the wrong usage of the prefix removal array action
by just using the new util function that does these
actions correctly.
Add in a couple of unit tests to verify the jsonp merging
and usage works as expected.

Just cleans up some repeated strings into module constants + a util function to
do the boothook prefix cleanup (before writing).

Jsonpatch is a new RFC standard for merging
json-like structures which the cloud-init
cloud-config is one such structure. To use this
in a limited fashion (to start) add the ability
for the cloud-config handler to accept this
content-type and use it as an alternate way to
merge new cloud-config sections into the accumulated
cloud-config.

Previously we'd not invoked reload-configuration because doing so
caused issues with upstart. Now, instead, determine if we can invoke it.

The new change for merging works well in the mergedict case
but the default merging type for cloud config needs to reflect
how yaml was loaded in bulk, which is the same as the replacing
keys merging type that is now provided.

For now, we disable reloading upstart jobs due to bug 1124384.
At some point in the future, we could enable it again when that
bug is fixed.
The change here allows for a boothook in a multipart input to write the
file '/run/cloud-init-upstart-reload' and then have configuration
reloaded.
|
|
|
|
Invoking 'initctl reload-configuration' is only required if inotify
does not work. overlayroot does not support inotify. So, we just
call initctl always, which wont hurt anything.

After user data handling splits apart all the different
content types into there various mime messages it is
nice to be able to have each message specify how it should
be merged (mainly for cloud-config or cloud-archive) into
the single cloud config that is eventually used. This
starts to add a plugable merging framework and the
needed components to activate said headers and merging.

attempt the unicode-escape path.
|
|
it has contents which are in unicode which seems
to cause python to blow-up when this happens since
'string-escape' doesn't work on unicode (at least in 2.6).

make pep8 now is silent on precise's pep8 ( 0.6.1-2ubuntu2).
|
|
A previous commit of mine here tried to apply a trivial fix
to avoid a warning on empty content type. Instead, it made
the empty content type call a handler which did not exist.
This instead logs warning on unknown non-empty payload.
It logs debug on empty payload.

imports and call_begin passes.
2. Fixup the 'test__init__.py' file to now be working again.
|
|
|
|
search module 'prefixes'
that also has a potential set of required attributes.
2. Use this new importer to find the distro class, the userdata handler modules, the config modules
and the datasource modules, if none can be found error out accordingly.
