Currently the setting of PLDHashTable::ops is very haphazard. - PLDHashTable has no constructor, so it's not auto-nulled, so lots of places null it themselves. - In the fallible PLDHashTable::Init() function, if the entry storage allocation fails we'll be left with a table that has |ops| set -- indicating it's been initialized -- but has null entry storage. I'm not certain this can cause problems but it feels unsafe, and some (but not all) callers of Init() null it on failure. - PLDHashTable does not null |ops| in Finish(), so some (but not all) callers do this themselves. This patch makes things simpler. - It adds a constructor that zeroes |ops|. - It modifies Init() so that it only sets |ops| once success is ensured. - It zeroes |ops| in Finish(). - Finally, it removes all the now-unnecessary |ops| nulling done by the users of PLDHashTable. --HG-- extra : rebase_source : bb34979c218d152562a2f9c7e5215256c111cc5b |
