Partitioning and freeing disk space

Question

I am running MySql innodb with innodb_file_per_table.

As a daily script, I would like to create a new partition for a set of tables, as well as delete yesterday's partitions. What command would need to be run to delete the old partitions to free up the disk space? I would like to avoid having a system that runs out of disk space because of the database disk usage. I would also like to avoid having to shut down Mysql.

Edit: I have read that discarding the tablespace should delete the .ibd files that take up most of the space.

ALTER TABLE tbl_name DISCARD TABLESPACE;

However there is a known bug using this command on partitioned tables.
