Easy to use retry decorator.

Step side
---------

It's fork: https://github.com/invl/retry

My changes had started from version 0.9.3 (see ChangeLog)


Features
--------

- No external dependency (stdlib only).
- (Optionally) Preserve function signatures (`pip install decorator`).
- Original traceback, easy to debug.


Installation
------------

.. code-block:: bash

    $ pip install retry-sh


API
---

retry decorator
^^^^^^^^^^^^^^^

Various retrying logic can be achieved by combination of arguments.


Examples
""""""""

.. code:: python

    from retry import retry

    @retry()
    def make_trouble():
        '''Retry until succeed'''

    @retry(ZeroDivisionError, tries=3, delay=2)
    def make_trouble():
        '''
        Retry on ZeroDivisionError,
        raise error after 3 attempts, sleep 2 seconds between attempts.
        '''

    @retry((ValueError, TypeError), delay=1, backoff=2)
    def make_trouble():
        '''
        Retry on ValueError or TypeError,
        sleep 1, 2, 4, 8, ... seconds between attempts.
        '''

    @retry((ValueError, TypeError), delay=1, backoff=2, max_delay=4)
    def make_trouble():
        '''
        Retry on ValueError or TypeError,
        sleep 1, 2, 4, 4, ... seconds between attempts.
        '''

    @retry(ValueError, delay=1, jitter=1)
    def make_trouble():
        '''
        Retry on ValueError,
        sleep 1, 2, 3, 4, ... seconds between attempts.
        '''

    # If you enable logging, you can get warnings like 'ValueError, retrying in
    # 1 seconds'
    if __name__ == '__main__':
        import logging
        logging.basicConfig()
        make_trouble()


retry_call
^^^^^^^^^^

This is very similar to the decorator, except that it takes a function and its arguments as parameters.
The use case behind it is to be able to dynamically adjust the retry arguments.

.. code:: python

    import requests

    from retry.api import retry_call


    def make_trouble(service, info=None):
        if not info:
            info = ''
        r = requests.get(service + info)
        return r.text


    def what_is_my_ip(approach=None):
        if approach == "optimistic":
            tries = 1
        elif approach == "conservative":
            tries = 3
        else:
            # skeptical
            tries = -1
        result = retry_call(
            make_trouble,
            fargs=["http://ipinfo.io/"],
            fkwargs={"info": "ip"},
            tries=tries
        )
        print(result)

    what_is_my_ip("conservative")
