Errors with ES 5.x

[Francesco Chicchiriccò <il...@apache.org>]

Hi all, I am moving an existing Ponymail deployment onto a new server.

I initially tried with ES 6.x, but I wasn't able to update index 
creation correctly, so I reverted to ES 5.x, with which everything seems 
to work except for the following.

When running

python3 edit-list.py --delete --source "idal2.tirasa.net"

I receive the following error:

Traceback (most recent call last): File "edit-list.py", line 180, in 
<module> terms File "/var/www/ponymail-src/tools/elastic.py", line 96, 
in search **kwargs File 
"/usr/local/lib/python3.6/dist-packages/elasticsearch/client/utils.py", 
line 76, in _wrapped return func(*args, params=params, **kwargs) File

line 186, in perform_request self._raise_error(response.status,

TransportError)(status_code, error_message, additional_info) 
elasticsearch.exceptions.RequestError: RequestError(400, 
'illegal_argument_exception', 'No search type for [scan]')

After a quick chat on IRC, it seems that the scan method was deprecated 
/ removed after 2.x, and then some maintenance is needed to make the 
above work with ES > 2.x

Moreover: are there plans to be compatible with ES 6.x?

TIA Regards.
