Add support for service running status and restoring at startup.
Now ServiceHandler stores a persistent status of the service, to know if
the service should be started at startup (or reloaded when reload command
is called). To do that it inherits from Restorable, so restarting and
committing is now not done at _restore() any more. InetdHandler now
inherits from ServiceHandler to take advantage of its features.
ServiceHandler now support callables _service_{start,stop,restart,reload}
attributes to ease the customization.
PppHandler is a special case where each connection has it own running
status. All start, stop, restart and reload takes the name argument as
optional. If a name is not provided, all connections are processed. On
restart, all connections are (re)started, on reload (and at startup), only the previous
running connectinos are restarted.
ConfigWriter's _write_config() now can return True to indicate that commit
command shouldn't reload the service.
VrrpHandler now uses python's kill to stop the service.
Use more consistent getter name in ContainerSubHandler.
Now the method to access to the container attribute is named _attr() (and
_vattr) instead of _cont() (and _vcont). The method accept now an optional
'attr' argument to act as a setter.
Add support to "operation tagging" to ListSubHandler and DictSubHandler.
"Operation tagging" means that if the contained objects has an _add,
_update or _delete attribute, it set them to true when the item is
added, updated or deleted respectively (in case that it's deleted, it's
not removed from the container, but it's not listed either, i.e. the
items are "logically" deleted, not really removed from the container).
Now ListSubHandler and DictSubHandler ihnerit from a new class
ContainerSubHandler which handles 95% of the code. Because of this, now
the "magic" attributes starts with _cont_ instead of _list_ or _dict_.
Existing handler were updated, but new ones should take this into
account.
Add a new, backward compatible, way to specify specific config dirs.
Now _config_writer_cfg_dir could be a dictionary instead of a string.
The dictionary maps template filenames to directories where to generate
(render) the configure files.
Raise a CommandNotFoundError if updating an object without update().
When a DictSubHandler try to update an object that doesn't have an
update() method, it raises a CommandNotFoundError to emulate that the
update command doesn't exist.
Rollback did never worked right on composed handlers (handlers with
sub-handlers) because when the class attributes were unpickled, they were
bounded to a new object instance, and the sub-handlers references were
never updated (the sub-handler referenced directly the handler attributes).
Now all sub-handlers references the handler object itself (called parent)
so when the unpikle is done, all can reference to the same objects.
Use a handler object as the root dispatcher handler instead of a dict.
Now the dispatcher use a handler object as the root handler. This way you
can inherit your root handler from Handler and get the useful 'help' and
'coommands' commands for free.
A new module is created: services.util which has a lot of helper classes
and functions to do common tasks of service handlers. Actual classes are:
Persistent, Restorable, ConfigWriter, ServiceHandler, InitdHandler and
TransactionalHandler (see documentation for details).
A call() function is provided as a simple wrapper for subprocess.call() to
execute simple commands. It can raise and ExecutionError, as a wrapper for
subprocess.call exceptions or ReturnNot0Error if the returned value is not
0.
Se modifica para que haga el flush ante un commit
y ademas se parse la salida del ip link list para
cargar en el init los devices y direcciones mac de
cada device
Se modifica config.py para que levante un DnsHandler.
Se modifica pymindaemon para que en caso de error 0 agregue
un fin de linea.
Se heredan las excepciones de Dns del HandlerError
.Se corrije el _write_config para que se comporte segun lo
esperado.
Add support for quoted and keyword arguments to the Dispatcher.
Now it's possible to dispatch commands with quoted arguments, like:
echo "hello world"
Keyword arguments are supported too, you can write something like:
set variable=value
and the handler for set will be called like set(variable="value").
Add help messages and command listing to dispatcher handlers.
Now the @handle decorator takes a mandatory help argument to specify a
short help string for that handler. A new functions get_help() is added to
the dispatcher module to get the help string from a handler.
A new base Handler class is provided in dispatcher module to automatically
have a 'help' and 'commands' commands available.
Now all errors that should be reported back to the pymin client should
inherit from dispatcher.HandlerError. Any other error is reported to the
client as an internal server error and it's printed in the daemon standard
output for debugging purposes. A new line is now appended to errors
reported to the client for better consistency with OK responses.
Use the serializer mode to automatically serialize handlers results.
Handlers now don't have to worry about serialization. All they have to do
is return list of values (which can be lists or iterable object). Then the
PyminDaemon serialize them to UTF-8 encoded CSV strings and send them
through socket.
