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/llui/llurlentry.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'indra/llui/llurlentry.cpp') diff --git a/indra/llui/llurlentry.cpp b/indra/llui/llurlentry.cpp index 6db0d88998..adefae6e2d 100755 --- a/indra/llui/llurlentry.cpp +++ b/indra/llui/llurlentry.cpp @@ -957,7 +957,7 @@ std::string LLUrlEntryObjectIM::getLocation(const std::string &url) const // LLUrlEntryParcel statics.
