Fix flowdetails meta size

2021-05-03T08:16:10+00:00

meta field in flowdetails is defined as a JSON data type, but its data
type is 'text' in mysql, which is limited to 64kbytes. JSON data type
should have the same size as a LONGTEXT.

Use unittest.mock instead of mock

2021-04-27T21:47:11+00:00

The mock third party library was needed for mock support in py2
runtimes. Since we now only support py36 and later, we can use the
standard lib unittest.mock module instead.

Merge "Add sentinel redis support"

2020-08-24T23:51:33+00:00

Avoid endless loop on StorageFailure

2020-08-24T13:16:54+00:00

If an error occures with writing atom detail in database(
persistence backend) flow execution enters an endless loop
throwing errors and retrying to save details.

Avoid this situation and log exception message.

Add sentinel redis support

2020-08-05T13:03:25+00:00

Redis client has an ability to connect to Redis server
using Sentinel[1] (especially important for Redis clusters),
but this ability was missing here.

Allow to pass 'sentinel' variable to Redis conf, extend
_make_client to use sentinel for that case.

Switch from unittest2 compat methods to Python 3.x methods

2020-07-05T12:04:04+00:00

With the removal of Python 2.x we can remove the unittest2 compat
wrappers and switch to assertCountEqual instead of assertItemsEqual

We have been able to use them since then, because
testtools required unittest2, which still included it. With testtools
removing Python 2.7 support [3][4], we will lose support for
assertItemsEqual, so we should switch to use assertCountEqual.

Stop to use the future module.

2020-06-02T19:00:56+00:00

The __future__ module [1] was used in this context to ensure compatibility
between python 2 and python 3.

We previously dropped the support of python 2.7 [2] and now we only support
python 3 so we don't need to continue to use this module and the imports
listed below.

Imports commonly used and their related PEPs:
- `division` is related to PEP 238 [3]
- `print_function` is related to PEP 3105 [4]
- `unicode_literals` is related to PEP 3112 [5]
- `with_statement` is related to PEP 343 [6]
- `absolute_import` is related to PEP 328 [7]
