From: Zhou Zheng Sheng <zhshzhou(a)linux.vnet.ibm.com>
Though Kimchi can automatically discover and load plugin Python modules
when kimchid starts, the packaging subsystem is not as smart. Downstream
plugin developers have to insert entries in Kimchi configure.ac and
contrib/kimchi.spec.*.in to compile and package plugin files. This is
not scalable.
This patch proposes a mechanism to make packaging scripts smarter to
discover and build plugins dynamically, so that the plugin code is
actually "plugable" to the packaging subsystem. The plugin developer
just places the pluginX code to plugins/pluginX, then uses
"./autogen.sh --with-plugins=pluginX" to generate the packaging scripts
for pluginX. We no longer have to change upstream Kimchi configure.ac,
Makefile.am and kimchi.spec.*.in.
To compile with plugins, use the following command.
./autogen.sh --with-plugins=plugin1,plugin2,... && make
To build kimchi-plugin1.rpm, kimchi-plugin2.rpm and kimchi.rpm, use the
following command.
./autogen.sh --system --with-plugins=plugin1,plugin2 && make && make
rpm
To build only kimchi.rpm, use the following command
./autogen.sh --system && make && make rpm
This patch makes use of the "include" functions in autoconf and RPM
spec. The basic idea is that each plugin provides two files as follow.
plugins/PLUGIN_NAME/configure.m4
plugins/PLUGIN_NAME/plugin.spec
Then autogen.sh catenates all plugins/{enabled_plugins}/configure.m4
into one big plugins/plugins.m4. In configure.ac, it includes
plugins/plugins.m4. When we invoke "make rpm", the Makefil scripts does
the similar catenation of plugins/{enabled_plugins}/plugin.spec into
plugins/plugins.spec, and have kimchi.spec include this file.
Since the Debian packaging system is a different story, future patches
shall be submitted to make Kimchi deb packaging code plugable.
