[jira] [Commented] (CASSANDRA-10190) Python 3 support for cqlsh

["Patrick Bannister (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-10190?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16882929#comment-16882929 ] 

Patrick Bannister commented on CASSANDRA-10190:
-----------------------------------------------

[~spodxx@gmail.com], yes, those are the current branches.

For this ticket, the immediate goals are:
* Port cqlshlib to run on Python 3.6 and Python 2.7
* Get the cqlshlib unit tests to parity between Python 2.7 and Python 3.6, except for documented cases with external problems, such as cases where Python 3 breaks the driver

The dtest branch we're using doesn't enable the remaining dtests, it only gets the currently enabled dtests working. I would like to merge these changes to get cqlshlib ported first, before taking on the remaining dtests. It's more urgent to port cqlshlib. It would also help manage the scope of the problem to take care of cqlshlib before dealing with the remaining dtests.

As for breaking out the cqlshlib tests, my recommendation is to continue delivering them as part of cqlshlib itself, because it feels wrong to break the tests away from the repo. But we can address this question separately, on CASSANDRA-14990.

> Users who operate in a Python 3 environment may have trouble launching cqlsh. Could we please update cqlsh's syntax to run in Python 3?
> As a workaround, users can setup pyenv, and cd to a directory with a .python-version containing "2.7". But it would be nice if cqlsh supported modern Python versions out of the box.
