Subject [jira] [Commented] (CASSANDRA-10853) deb package migration to dh_python2
Date Fri, 22 Apr 2016 02:05:13 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10853?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15253177#comment-15253177

Stefania commented on CASSANDRA-10853:
--------------------------------------

I've opened CASSANDRA-11630 to make the dependency on Cython optional, and not necessary when
the {{--no-compile}} flag is passed to _setup.py_. 

The intention in CASSANDRA-11053 was to keep the package arch independent and let people build
the Cython extensions manually for performance reasons (see this [blog|http://www.datastax.com/dev/blog/six-parameters-affecting-cqlsh-copy-from-performance]).
The performance improvement of compiling _copyutil.py_ is minimal (5%), what really helps
is compiling the driver, which we don't do at the moment. However, this may well change in
future if we optimize _copyutil.py__ further. So let me know what you prefer, to tackle the
problem now and keep the extensions in the package, or make them optional.

> I'm working on a deb job in jenkins, and I had forgotten to open a bug for this. There
is no urgent need, since {{python-support}} is in Jessie, but this package is currently in
transition to be removed.
> http://deb.li/dhs2p
> During deb build:
> {noformat}
> dh_pysupport: This program is deprecated, you should use dh_python2 instead. Migration
guide: http://deb.li/dhs2p
