From 2a56ab44360aa49bd0df9281efc8a8a97a510013 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Fri, 22 Nov 2019 11:58:27 -0500 Subject: DRTVWR-476, SL-12197: Don't throw Stopping from main coroutine. The new LLCoros::Stop exception is intended to terminate long-lived coroutines -- not interrupt mainstream shutdown processing. Only throw it on an explicitly-launched coroutine. Make LLCoros::getName() (used by the above test) static. As with other LLCoros methods, it might be called after the LLCoros LLSingleton instance has been deleted. Requiring the caller to call instance() implies a possible need to also call wasDeleted(). Encapsulate that nuance into a static method instead. --- indra/llcommon/llcoros.cpp | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'indra/llcommon/llcoros.cpp') diff --git a/indra/llcommon/llcoros.cpp b/indra/llcommon/llcoros.cpp index febe74b559..5f940de52b 100644 --- a/indra/llcommon/llcoros.cpp +++ b/indra/llcommon/llcoros.cpp @@ -192,7 +192,8 @@ bool LLCoros::kill(const std::string& name) } |*==========================================================================*/ -std::string LLCoros::getName() const +//static +std::string LLCoros::getName() { return get_CoroData("getName()").mName; } @@ -320,12 +321,21 @@ void LLCoros::toplevel(std::string name, callable_t callable) } } +//static void LLCoros::checkStop() { if (wasDeleted()) { LLTHROW(Shutdown("LLCoros was deleted")); } + // do this AFTER the check above, because getName() depends on + // get_CoroData(), which depends on the local_ptr in our instance(). + if (getName().empty()) + { + // Our Stop exception and its subclasses are intended to stop loitering + // coroutines.
