Inconsistent output of 'mogadm domain list' encountered

[Chaos Wang]

Hi, I use the MogileFS code from official svn trunk to do some test. But when I do some domain addition/deletion operations, the output of 'mogadm domain list' becomes inconsistent between different calls. This phenomenon can be repeated by following steps: mogadm domain add xxx mogadm domain delete xxx mogadm domain add yyy mogadm domain list (several times) I thinks the problem is in the invalidate_cache() method in MogileFS::Domain module, because it forget to clean up the hash map %singleton (of_dmid(), which is called in domains(), used this hash map before trying %id2name map). After made the following changes in MogileFS::Domain::invalidate_cache(), the phenomenon doesn't show up again: --code begin-- sub invalidate_cache { ... %id2name=(); %name2id=(); %singleton=(); # XXX: this is newly added ... --code end-- And I have another question: does classes belong to certain domain? If so, why delete a domain does not clean up the classes under it?
