From 62527e6f18f0a035a234cf584e31f7eea93fd4a7 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Tue, 18 Aug 2015 17:05:29 -0400 Subject: MAINT-5506: Fix ugly timing bug in llurlentry static initialization. The problem was that class-static LLUrlEntryParcel::sRegionHost was being initialized by copying class-static LLHost::invalid. Naturally, these two statics are initialized in different source files. Since C++ makes no promises about the relative order in which objects in different object files are initialized, it seems we hit a case in which we were trying to initialize sRegionHost by copying a completely uninitialized LLHost::invalid. In general we might attempt to address such cross-translation-unit issues by introducing an LLSingleton. But in this particular case, the punch line is that LLHost::invalid is explicitly constructed identically to a default-constructed LLHost! In other words, LLHost::invalid provides nothing we couldn't get from LLHost(). All it gives us is an opportunity for glitches such as the above. Remove LLHost::invalid and all references, replacing with LLHost(). --- indra/newview/llfloatergodtools.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'indra/newview/llfloatergodtools.cpp') diff --git a/indra/newview/llfloatergodtools.cpp b/indra/newview/llfloatergodtools.cpp index 37774fbc5c..adc7f71586 100755 --- a/indra/newview/llfloatergodtools.cpp +++ b/indra/newview/llfloatergodtools.cpp @@ -115,7 +115,7 @@ void LLFloaterGodTools::refreshAll() LLFloaterGodTools::LLFloaterGodTools(const LLSD& key) : LLFloater(key), - mCurrentHost(LLHost::invalid), + mCurrentHost(LLHost()), mUpdateTimer() { mFactoryMap["grid"] = LLCallbackMap(createPanelGrid, this); @@ -180,7 +180,7 @@ void LLFloaterGodTools::updatePopup(LLCoordGL center, MASK mask) // virtual void LLFloaterGodTools::draw() { - if (mCurrentHost == LLHost::invalid) + if (mCurrentHost == LLHost()) { if (mUpdateTimer.getElapsedTimeF32() > SECONDS_BETWEEN_UPDATE_REQUESTS) { @@ -325,7 +325,7 @@ void LLFloaterGodTools::sendRegionInfoRequest() { if (mPanelRegionTools) mPanelRegionTools->clearAllWidgets(); if (mPanelObjectTools) mPanelObjectTools->clearAllWidgets(); - mCurrentHost = LLHost::invalid; + mCurrentHost = LLHost(); mUpdateTimer.reset(); LLMessageSystem* msg = gMessageSystem; -- cgit v1.2.3
