Fix "DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc'" #1309

Closed ozooxo closed 3 years ago

ozooxo commented 3 years ago

Bottle is currently using collections.abc https://github.com/bottlepy/bottle/blob/f9b1849db4dd724e36a93a1032be592193fba581/bottle.py#L125

It is causing this deprecation warning (my warning is from 0.12.17, but the newest (0.12.19) has the same problem):

/usr/local/bin/bottle.py:87: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3,and in 3.9 it will stop working from collections import MutableMapping as DictMixin

Could you please modify it as Python core suggested, so we can get rid of this warning?
