[debian-mysql] Bug#825076: Package links against libmysqlclient_r

Package: cacti-spine
Version: 0.8.8h-1
Tags: patch

Dear Maintainer,

Please stop linking against libmysqlclient_r and link directly against
libmysqlclient instead.

Your package currently links against libmysqlclient_r. libmysqlclient_r
was the thread-safe version of libmysqlclient in previous MySQL
releases. However, libmysqlclient has been itself been made thread-safe
since before the current libmysqlclient18. Thus libmysqlclient_r is
currently deprecated and provided as a compatibility symlink only, and
will disappear in MySQL 5.7. This change can be made now, in advance of
a possible future transition to libmysqlclient20, which does not provide
the _r variant.

For cacti-spine, we have done this in Ubuntu with the attached quilt
patch, which I believe is also applicable to Debian.

Thanks,
