Closed Bug 1179657 Opened 7 years ago Closed 7 years ago
When PL_DHASHMETER is enabled, we collect lots of stats about each PLDHashTable. You can then print these out on a per-table basis by calling PL_DHashTableDumpMeter(), but you have to provide a PLDHashEnumerator function. This code is unused and totally busted and has been for who knows how long. (PLDHashStats has two fields named |mSearches|, for example.) IMO this whole approach isn't a good way of doing stats gathering: it's too invasive, too prone to breakage, and too awkward to use. A better way is to just insert temporary, ad hoc fprintf(stderr, ...) calls in the places of interest and then use simple post-processing to gather counts. I've been doing this for years, and a while back Brendan -- who I assume is the author of this code, because it sure feels like his style -- admitted to me that he'd come around to my opinion on this topic. Also, this code's presence complicates the removal of PL_DHashTableEnumerate(). It doesn't make removal impossible, but it's yet one more reason to remove it.
