Should close#400.
* Add parse_entity
* Add parse_entities
* Add MessageEntity types as constants to MessageEntity.
* Add MAX_MESSAGE_ENTITIES to constants.py
Note: the value has been found by experimentation as opposed to extracted from the api docs.
* Add tests for parse_entity and parse_entities
* Create a Request class which maintains its own connection pool
* When creating a Bot instance a new Request instance will be created if one wasn't supplied.
* Updater is responsible for creating a Request instance if a Bot instance wasn't provided.
* Dispatcher: add method to run async functions without decorator
* Dispatcher can now run as a singleton (allowing run_async decorator to work) as it always did and as multiple instances (where run_async decorator will raise RuntimeError)
* initial commit for conversationhandler and example
* implement simple Promise for run_async/conversationhandler
* refactor Promise._done to done
* add handling for timed out Promises
* correctly handle promises with None results
* fix handling tuple states
* update comments on example
* Added a first test on the ConversationHandler.
* Fixed a small typo.
* Yapf'd.
* add sphinx doc for conversation handler
* fix title for callbackqueryhandler sphinx docs
- start the jobqueue (by default) during __init__() instead of during
put()
- protect self._next_peek and self.__tick with a Lock
- rename self._start() to self._main_loop()
- stop() is now blocking until the event loop thread exits
during test_bootstrap_retries_fail() there is an exception raised (by
design): TelegramError('test')
For a reason I haven't managed to pinpoint the above exception in its
precise timing caused the Updater to be left in a state which is
'self.running == False', but the dispatcher threads already initialized.
This patch identifies this extreme case and makes sure to go over the
stop procedure.
