# Retrying
|
||||
|
||||
Retrying is an Apache 2.0 licensed general-purpose retrying library, written in
|
||||
Python, to simplify the task of adding retry behavior to just about anything.
|
||||
|
||||
The simplest use case is retrying a flaky function whenever an Exception occurs
|
||||
until a value is returned.
|
||||
|
||||
```python
|
||||
import random
|
||||
from retrying import retry
|
||||
|
||||
@retry
|
||||
def do_something_unreliable():
|
||||
if random.randint(0, 10) > 1:
|
||||
raise IOError("Broken sauce, everything is hosed!!!111one")
|
||||
else:
|
||||
return "Awesome sauce!"
|
||||
|
||||
print(do_something_unreliable())
|
||||
```
|
||||
|
||||
## Features
|
||||
|
||||
- Generic Decorator API
|
||||
- Specify stop condition (i.e. limit by number of attempts)
|
||||
- Specify wait condition (i.e. exponential backoff sleeping between attempts)
|
||||
- Customize retrying on Exceptions
|
||||
- Customize retrying on expected returned result
|
||||
|
||||
## Examples
|
||||
|
||||
As you saw above, the default behavior is to retry forever without waiting.
|
||||
|
||||
```python
|
||||
@retry
|
||||
def never_give_up_never_surrender():
|
||||
print("Retry forever ignoring Exceptions, don't wait between retries")
|
||||
```
|
||||
|
||||
Let's be a little less persistent and set some boundaries, such as the number of attempts before giving up.
|
||||
|
||||
```python
|
||||
@retry(stop_max_attempt_number=7)
|
||||
def stop_after_7_attempts():
|
||||
print("Stopping after 7 attempts")
|
||||
```
|
||||
|
||||
We don't have all day, so let's set a boundary for how long we should be retrying stuff.
|
||||
|
||||
```python
|
||||
@retry(stop_max_delay=10000)
|
||||
def stop_after_10_s():
|
||||
print("Stopping after 10 seconds")
|
||||
```
|
||||
|
||||
Most things don't like to be polled as fast as possible, so let's just wait 2 seconds between retries.
|
||||
|
||||
```python
|
||||
@retry(wait_fixed=2000)
|
||||
def wait_2_s():
|
||||
print("Wait 2 second between retries")
|
||||
```
|
||||
|
||||
Some things perform best with a bit of randomness injected.
|
||||
|
||||
```python
|
||||
@retry(wait_random_min=1000, wait_random_max=2000)
|
||||
def wait_random_1_to_2_s():
|
||||
print("Randomly wait 1 to 2 seconds between retries")
|
||||
```
|
||||
|
||||
Then again, it's hard to beat exponential backoff when retrying distributed services and other remote endpoints.
|
||||
|
||||
```python
|
||||
@retry(wait_exponential_multiplier=1000, wait_exponential_max=10000)
|
||||
def wait_exponential_1000():
|
||||
print("Wait 2^x * 1000 milliseconds between each retry, up to 10 seconds, then 10 seconds afterwards")
|
||||
```
|
||||
|
||||
We have a few options for dealing with retries that raise specific or general exceptions, as in the cases here.
|
||||
|
||||
```python
|
||||
def retry_if_io_error(exception):
|
||||
"""Return True if we should retry (in this case when it's an IOError), False otherwise"""
|
||||
return isinstance(exception, IOError)
|
||||
|
||||
@retry(retry_on_exception=retry_if_io_error)
|
||||
def might_io_error():
|
||||
print("Retry forever with no wait if an IOError occurs, raise any other errors")
|
||||
|
||||
@retry(retry_on_exception=retry_if_io_error, wrap_exception=True)
|
||||
def only_raise_retry_error_when_not_io_error():
|
||||
print("Retry forever with no wait if an IOError occurs, raise any other errors wrapped in RetryError")
|
||||
```
|
||||
|
||||
We can also use the result of the function to alter the behavior of retrying.
|
||||
|
||||
```python
|
||||
def retry_if_result_none(result):
|
||||
"""Return True if we should retry (in this case when result is None), False otherwise"""
|
||||
return result is None
|
||||
|
||||
@retry(retry_on_result=retry_if_result_none)
|
||||
def might_return_none():
|
||||
print("Retry forever ignoring Exceptions with no wait if return value is None")
|
||||
```
|
||||
|
||||
Any combination of stop, wait, etc. is also supported to give you the freedom to mix and match.
|
||||
|
||||

Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||
To apply the Apache License to your work, attach the following
|
||||
boilerplate notice, with the fields enclosed by brackets "[]"
