Feature #11174

Updated by John Spray almost 6 years ago

There are a ton of places where we assert certain thing are consistent within the MDCache+MDLog+etc state. Asserting is a good thing, but we could leave more useful stuff around than a stack trace. Things like:


* an MDCache dump

* an OpTracker ops in flight dump

* a clog() message

* a message to MDSMonitor to indicate our failure so that nobody has to wait for us to go laggy

This mechanism would *not* replace normal assertions for things like validity of pointers or iterators, as once those are violated we can no longer safely traverse any of our internal data structures.
