From f13d630ff98eb5b5505f1db3e7f207175b51b237 Mon Sep 17 00:00:00 2001

Subject: [PATCH 04/12] Issue 51076 - remove unnecessary slapi entry dups
Description: So the problem is that slapi_search_internal_get_entry()
duplicates the entry twice. It does that as a convenience
where it will allocate a pblock, do the search, copy
the entry, free search results from the pblock, and then
free the pblock itself. I basically split this function
into two functions. One function allocates the pblock,
does the search and returns the entry. The other function
frees the entries and pblock.
99% of time when we call slapi_search_internal_get_entry()
we are just reading it and freeing it. It's not being
consumed. In these cases we can use the two function
approach eliminates an extra slapi_entry_dup(). Over the
time of an operation/connection we can save quite a bit
of mallocing/freeing. This could also help with memory
fragmentation.
ASAN: passed
