Comments on: MySQL InnoDB and table renaming don’t play well… http://www.masterzen.fr/2009/10/15/mysql-innodb-and-table-renaming-dont-play-well/ Journey in a software world...

I turned the problem trying to find a code fix by myself, and I don't see any obvious way: at least the new name still needs to be allocated somewhere. One evident possible fix is to reuse the memory of the old name if the new name is shorter than the previous one. I can still arrange my rank script to use table name of same length, that becomes ugly :-) What is questionable nowadays if it makes sense to use the table heap. We have pretty good and fast allocators (TC malloc or others), so I'm sure re-writing all the mem_heap stuff to use it can be worthwhile. @Domas,

One of ways is of course fixing/patching yourself. Other is moving to BLACKHOLE (though it may have other nasty bugs). And of course, you can just wait for official fix. To make it faster you can always poke your friendly MySQL Support engineer ;-) So, you filed a bug - it will get fixed soon then.
