Plugin API: Add datasource interception extension point
This change extends the plugin API to support monitoring of Gerrit's
SQL activity by providing the extension point to create a DataSource
proxy to intercept execution of SQL statements.
To activate SQL monitoring the following must be done:
Add the interceptor class to gerrit.config:
dataSourceInterceptorClass = javamelody.JavamelodyInterceptor
Implement the interface DataSourceInterceptor:
public class JavamelodyInterceptor implements DataSourceInterceptor {
@Override
public DataSource intercept(String name, DataSource dataSource) {
return JdbcWrapper.SINGLETON.createDataSourceProxy(name, dataSource);
}
}
Put the jar containing the interceptor into $gerrit_site/lib directory.
Working example of this concept can be found in javamelody-plugin.
