2016-09-15MAINT-5232: Normalize LLSingleton subclasses.Nat Goodspeed
A shocking number of LLSingleton subclasses had public constructors -- and in several instances, were being explicitly instantiated independently of the LLSingleton machinery. This breaks the new LLSingleton dependency-tracking machinery. It seems only fair that if you say you want an LLSingleton, there should only be ONE INSTANCE! Introduce LLSINGLETON() and LLSINGLETON_EMPTY_CTOR() macros. These handle the friend class LLSingleton<whatevah>; and explicitly declare a private nullary constructor. To try to enforce the LLSINGLETON() convention, introduce a new pure virtual LLSingleton method you_must_use_LLSINGLETON_macro() which is, as you might suspect, defined by the macro. If you declare an LLSingleton subclass without using LLSINGLETON() or LLSINGLETON_EMPTY_CTOR() in the class body, you can't instantiate the subclass for lack of a you_must_use_LLSINGLETON_macro() implementation -- which will hopefully remind the coder. Trawl through ALL LLSingleton subclass definitions, sprinkling in LLSINGLETON() or LLSINGLETON_EMPTY_CTOR() as appropriate. Remove all explicit constructor declarations, public or private, along with relevant 'friend class LLSingleton<myself>' declarations. Where destructors are declared, move them into private section as well. Where the constructor was inline but nontrivial, move out of class body. Fix several LLSingleton abuses revealed by making ctors/dtors private: LLGlobalEconomy was both an LLSingleton and the base class for LLRegionEconomy, a non-LLSingleton. (Therefore every LLRegionEconomy instance contained another instance of the LLGlobalEconomy "singleton.") Extract LLBaseEconomy; LLGlobalEconomy is now a trivial subclass of that. LLRegionEconomy, as you might suspect, now derives from LLBaseEconomy. LLToolGrab, an LLSingleton, was also explicitly instantiated by LLToolCompGun's constructor. Extract LLToolGrabBase, explicitly instantiated, with trivial subclass LLToolGrab, the LLSingleton instance. (WARNING: LLToolGrabBase methods have an unnerving tendency to go after LLToolGrab::getInstance(). I DO NOT KNOW what should be the relationship between the instance in LLToolCompGun and the LLToolGrab singleton instance.) LLGridManager declared a variant constructor accepting (const std::string&), with the comment: // initialize with an explicity grid file for testing. As there is no evidence of this being called from anywhere, delete it. LLChicletBar's constructor accepted an optional (const LLSD&). As the LLSD parameter wasn't used, and as there is no evidence of it being passed from anywhere, delete the parameter. LLViewerWindow::shutdownViews() was checking LLNavigationBar:: instanceExists(), then deleting its getInstance() pointer -- leaving a dangling LLSingleton instance pointer, a land mine if any subsequent code should attempt to reference it. Use deleteSingleton() instead. ~LLAppViewer() was calling LLViewerEventRecorder::instance() and then explicitly calling ~LLViewerEventRecorder() on that instance -- leaving the LLSingleton instance pointer pointing to an allocated-but-destroyed instance. Use deleteSingleton() instead.

2015-05-27MAINT-5232: Extract LLInitClass, LLDestroyClass from llui/llui.hNat Goodspeed
to a new llcommon/llinitdestroyclass.h. This mechanism is so general -- but has so many related moving parts -- that (a) it deserves to be in a header file all its own, instead of conflated with llui.h, and (b) it should be in llcommon where anyone can use it. It has no dependencies whatsoever on llui or anything viewer-specific. In this very changeset we changed one #include "llui.h" whose comment admits that it was only dragged in for LLDestroyClass.
