One of these is maintained * for each region encountered and the 'current' region is available * as a simple reference. Each thread (presently two) interested * in participating in these stats gets an instance of the * LLViewerAssetStats class so that threads are completely * independent. * * The idea of a current region is used for simplicity and speed * of categorization. Each metrics event could have taken a * region uuid argument resulting in a suitable lookup. Arguments * against this design include: * * - Region uuid not trivially available to caller. * - Cost (cpu, disruption in real work flow) too high. * - Additional precision not really meaningful. * * By itself, the LLViewerAssetStats class is thread- and * viewer-agnostic and can be used anywhere without assumptions * of global pointers and other context. For the viewer, * a set of free functions are provided in the namespace * LLViewerAssetStatsFF which *do* implement viewer-native * policies about per-thread globals and will do correct * defensive tests of same. * * References * * Project: * * * Test Plan: * * * Jiras: * * * Unit Tests: * indra/newview/tests/llviewerassetstats_test.cpp * */ namespace LLViewerAssetStatsFF { static EViewerAssetCategories asset_type_to_category(const LLViewerAssetType::EType at, bool with_http, bool is_temp) { // For statistical purposes, we divide GETs into several // populations of asset fetches: // - textures which are de-prioritized in the asset system // - wearables (clothing, bodyparts) which directly affect // user experiences when they log in // - sounds // - gestures, including animations // - everything else. // EViewerAssetCategories ret(EVACOtherGet); switch (at) { case LLAssetType::AT_TEXTURE: if (is_temp) ret = with_http ?
