From 285613b892f41d0c72c03b8551dd003f61a5f2be Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Wed, 3 Jun 2009 21:38:21 +0000 Subject: DEV-32777: Introduce LLCoros, an LLSingleton registry of named coroutine instances. LLCoros::launch() intends to address three issues: - ownership of coroutine instance - cleanup of coroutine instance when it terminates - central place to twiddle MSVC optimizations to bypass DEV-32777 crash. Initially coded on Mac; will address the third bullet on Windows. Adapt listenerNameForCoro() to consult LLCoros::getName() if applicable. Change LLLogin::Impl::connect() to use LLCoros::launch(). LLCoros::getName() relies on patch to boost::coroutines::coroutine::self to introduce get_id(). --- indra/viewer_components/login/lllogin.cpp | 28 +++++++++------------------- 1 file changed, 9 insertions(+), 19 deletions(-) (limited to 'indra/viewer_components') diff --git a/indra/viewer_components/login/lllogin.cpp b/indra/viewer_components/login/lllogin.cpp index 26b950b618..575a709761 100644 --- a/indra/viewer_components/login/lllogin.cpp +++ b/indra/viewer_components/login/lllogin.cpp @@ -44,8 +44,8 @@ #include "lllogin.h" #include -#include +#include "llcoros.h" #include "llevents.h" #include "lleventfilter.h" #include "lleventcoro.h" @@ -109,35 +109,25 @@ private: void login_(coroutine_type::self& self, const std::string& uri, const LLSD& credentials); - boost::scoped_ptr mCoro; LLEventStream mPump; LLSD mAuthResponse, mValidAuthResponse; }; void LLLogin::Impl::connect(const std::string& uri, const LLSD& credentials) { - // If there's a previous coroutine instance, and that instance is still - // active, destroying the instance will terminate the coroutine by - // throwing an exception, thus unwinding the stack and destroying all - // local objects.
