Author: Andrei Pelinescu-Onciul <[email protected]> Committer: Andrei Pelinescu-Onciul <[email protected]> Date: Mon Nov 30 12:29:20 2009 +0100 presence(k): fix off-by-one memory allocation Due to some missing '()' ( (...)?resource.len:event.len + 1 instead of ((...)?resource.len:event.len) + 1 ) sometimes the memory allocated was less with one byte then what was needed. The fixed version also replaces ?: with MAX_unsigned() (does the same thing and it's easier to read).
