Bug 665928 – media-tv/mythtv: Validate DEPEND on virtual/mysql

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Brian Evans (RETIRED) 2018-09-12 17:31:46 UTC]

THIS IS A MASS FILING TO ALL PACKAGE WITH A DEPEND ON virtual/mysql

As was announced on the gentoo-dev-announce mailing list[1],
virtual/mysql is no longer viable to depend on providing the client libraries
or the mysql_config tool.

Most uses of DEPEND="virtual/mysql" (or conditionals based upon it) will not
work in the future.

If this package (optionally) depends on libmysqlclient.so* or mysql_config for
building, you will need to have dev-db/mysql-connector-c as the DEPEND/RDEPEND.

If this package (optionally) depends on libmariadb.so* or mariadb_config for
building, you will need to have dev-db/mariadb-connector-c as the
DEPEND/RDEPEND.

If this package requires the server running locally, virtual/mysql is
acceptible for RDEPEND and only in DEPEND when tests demand it.

The rare exception when server only files are required at build time should you
keep a compatible server listed.

After 60 days, roughly mid-October 2018, remaining packages will be forcefully
changed to mysql-connector-c with little or no testing. The server packages
will drop their compatibility DEPEND shortly after.

I know that nobody's currently maintaining this. Here's what I'd suggest for addressing this one, and I'll attach a modified version of the existing 29.1 ebuild:

1. Remove the virtual/mysql dependency completely. As far as mysql connectivity (the client libraries) is concerned, the dependencies of other packages like dev-qt/qtsql:5[mysql], dev-perl/DBD-mysql, and dev-python/mysql-python will address that.

2. Make the actions in pkg_config() conditional on the existence of the /usr/bin/mysql client program.

Given that the server USE flag is being removed from mysql, this is probably the only solution that won't require an unnecessary full mysql server install on a frontend only system.

It's already on the user to install either mysql or mariadb on the backend, so I'd say this makes sense.

Tom

Mythtv depends on a mysql database running somewhere on the LAN. That is well documented my mythtv setup. Mythtv does not require that mysql be built on the same system it is installed on so the dependency is removed.
