From bf7faa3267e549b01131c6746202a5b6cda8e68a Mon Sep 17 00:00:00 2001 From: Henri Beauchamp Date: Mon, 6 Feb 2023 11:30:23 +0100 Subject: Faster and simpler inventory category hashing. This commit changes inventory category hashing from slow LLMD5 to fast HBXX128 hashing, and allows to use a simple LLUUID for the hash, instead of an LLMD5 instance. It also removes some old cruft dealing with unused baked texture hashing. --- indra/newview/llinventorymodel.cpp | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) (limited to 'indra/newview/llinventorymodel.cpp') diff --git a/indra/newview/llinventorymodel.cpp b/indra/newview/llinventorymodel.cpp index 6ba04cdff2..b41ad51fa4 100644 --- a/indra/newview/llinventorymodel.cpp +++ b/indra/newview/llinventorymodel.cpp @@ -62,6 +62,7 @@ #include "bufferarray.h" #include "bufferstream.h" #include "llcorehttputil.h" +#include "hbxxh.h" //#define DIFF_INVENTORY_FILES #ifdef DIFF_INVENTORY_FILES @@ -451,17 +452,16 @@ void LLInventoryModel::getDirectDescendentsOf(const LLUUID& cat_id, items = get_ptr_in_map(mParentChildItemTree, cat_id); } -LLMD5 LLInventoryModel::hashDirectDescendentNames(const LLUUID& cat_id) const +LLUUID LLInventoryModel::hashDirectDescendentNames(const LLUUID& cat_id) const { LLInventoryModel::cat_array_t* cat_array; LLInventoryModel::item_array_t* item_array; getDirectDescendentsOf(cat_id,cat_array,item_array); - LLMD5 item_name_hash; if (!item_array) { - item_name_hash.finalize(); - return item_name_hash; + return LLUUID::null; } + HBXXH128 item_name_hash; for (LLInventoryModel::item_array_t::const_iterator iter = item_array->begin(); iter != item_array->end(); iter++) @@ -471,8 +471,7 @@ LLMD5 LLInventoryModel::hashDirectDescendentNames(const LLUUID& cat_id) const continue; item_name_hash.update(item->getName()); } - item_name_hash.finalize(); - return item_name_hash; + return item_name_hash.digest(); } // SJB: Added version to lock the arrays to catch potential logic bugs -- cgit v1.3
