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.
EXP-1233 FIX -- Populate the toybox floater window with all FUI toolbar buttons indicated as such in the "commands.xml" definition.
EXP-1267 FIX -- Enable/disable buttons in the toybox
* Hooked up button callbacks to the toolbar buttons
* Fixed toybox button enable/disable to function properly and live update as
buttons change states.
* Removed the toybox toolbar background image
Reviewed by Leyla
* Command buttons are now enabled/disabled in toybox based on whether or not the
LLToolBarView has them anywhere.
* Commands now have argument to specify whether or not they should be in the
toybox.
* LLCommandId is now used a universal reference for commands.

EXP-1233 PROGRESS -- Populate the toybox floater window with all FUI toolbar buttons
EXP-1236 FIX -- The toybox floater should remember its position for the user
* Basic addCommand function to the LLToolBar. Need proper implementation.
* Added map for faster lookup of commands
* Toybox now adds commands to its toolbar for basic button setup
Reviewed by Richard.
EXP-1232 FIX -- Create class to load and hold all of the command meta data associated with FUI toolbar actions
* Added basic commands.xml file to define FUI-related toolbar actions. For now
a basic "avatar" and "places" button are defined.
* Added basic command manager to parse and hold strings that define potential
toolbar command actions.
* Broke out a separate floater function as a placeholder for the 3-state toolbar
floater toggling.
* LLUI::initClass now parses the new commands.xml file
