From 28a54c2f7b25b9fda763c51746701f0cd21c8018 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Tue, 22 Oct 2019 16:49:29 -0400 Subject: DRTVWR-476: Infrastructure to help manage long-lived coroutines. Introduce LLCoros::Stop exception, with subclasses Stopping, Stopped and Shutdown. Add LLCoros::checkStop(), intended to be called periodically by any coroutine with nontrivial lifespan. It checks the LLApp status and, unless isRunning(), throws one of these new exceptions. Make LLCoros::toplevel() catch Stop specially and log forcible coroutine termination. Now that LLApp status matters even in a test program, introduce a trivial LLTestApp subclass whose sole function is to make isRunning() true. (LLApp::setStatus() is protected: only a subclass can call it.) Add LLTestApp instances to lleventcoro_test.cpp and lllogin_test.cpp. Make LLCoros::toplevel() accept parameters by value rather than by const reference so we can continue using them even after context switches. Make private LLCoros::get_CoroData() static. Given that we've observed some coroutines living past LLCoros destruction, making the caller call LLCoros::instance() is more dangerous than encapsulating it within a static method -- since the encapsulated call can check LLCoros::wasDeleted() first and do something reasonable instead. This also eliminates the need for both a const and non-const overload. Defend LLCoros::delete_CoroData() (cleanup function for fiber_specific_ptr for CoroData, implicitly called after coroutine termination) against calls after ~LLCoros(). Add a status string to coroutine-local data, with LLCoro::setStatus(), getStatus() and RAII class TempStatus. Add an optional 'when' string argument to LLCoros::printActiveCoroutines(). Make ~LLCoros() print the coroutines still active at destruction. --- indra/llcommon/tests/lleventcoro_test.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'indra/llcommon/tests') diff --git a/indra/llcommon/tests/lleventcoro_test.cpp b/indra/llcommon/tests/lleventcoro_test.cpp index c13920eefd..032923a108 100644 --- a/indra/llcommon/tests/lleventcoro_test.cpp +++ b/indra/llcommon/tests/lleventcoro_test.cpp @@ -40,6 +40,7 @@ #include #include "../test/lltut.h" +#include "../test/lltestapp.h" #include "llsd.h" #include "llsdutil.h" #include "llevents.h" @@ -98,6 +99,7 @@ namespace tut std::string replyName, errorName, threw, stringdata; LLSD result, errordata; int which; + LLTestApp testApp; void explicit_wait(boost::shared_ptr>& cbp); void waitForEventOn1(); -- cgit v1.3
