2016-11-15DRTVWR-418: Fold windows64 into windows platform with new autobuild.Nat Goodspeed
autobuild 1.1 now supports expanding $variables within a config file -- support that was explicitly added to address this very problem. So now the windows platform in autobuild.xml uses $AUTOBUILD_ADDRSIZE, $AUTOBUILD_WIN_VSPLATFORM and $AUTOBUILD_WIN_CMAKE_GEN, which should handle most of the deltas between the windows platform and windows64. This permits removing the windows64 platform definition from autobuild.xml. The one remaining delta between the windows64 and windows platform definitions was -DLL_64BIT_BUILD=TRUE. But we can handle that instead by checking ADDRESS_SIZE. Change all existing references to WORD_SIZE to ADDRESS_SIZE instead, and set ADDRESS_SIZE to $AUTOBUILD_ADDRSIZE. Change the one existing LL_64BIT_BUILD reference to test (ADDRESS_SIZE EQUAL 64) instead.

2016-09-06MAINT-5232: Ensure that llcoro::get_id() returns distinct values.Nat Goodspeed
Until now, the "main coroutine" (the initial context) of each thread left LLCoros::Current() NULL. The trouble with that is that llcoro::get_id() returns that CoroData* as an opaque token, and we want distinct values for every stack in the process. That would not be true if the "main coroutine" on thread A returned the same value (NULL) as the "main coroutine" on thread B, and so forth. Give each thread's "main coroutine" a dummy heap CoroData instance of its own.

2016-09-03MAINT-5232: Add LLCoros::get_id() to identify the running coroutine.Nat Goodspeed
Change the module-static thread_specific_ptr to a function-static thread_specific_ptr so it will be initialized on demand -- since LLSingleton will need to rely on get_id(). Note that since LLCoros isa LLSingleton, we must take great care to avoid circularity. Introduce a private helper class LLCoros::Current to obtain and bind that thread_specific_ptr. Change all existing internal references from the static thread_specific_ptr to the new Current helper class.

2016-08-18MAINT-5011: Catch unhandled exceptions in LLCoros coroutines.Nat Goodspeed
Wrap coroutine call in try/catch in top-level coroutine wrapper function LLCoros::toplevel(). Distinguish exception classes derived from LLContinueError (log and continue) from all others (crash with LL_ERRS). Enhance CRASH_ON_UNHANDLED_EXCEPTIONS() and LOG_UNHANDLED_EXCEPTIONS() macros to accept a context string to supplement the log message. This lets us replace many places that called boost::current_exception_diagnostic_information() with LOG_UNHANDLED_EXCEPTIONS() instead, since the explicit calls were mostly to log supplemental information. Provide supplemental information (coroutine name, function parameters) for some of the previous LOG_UNHANDLED_EXCEPTIONS() calls. This information duplicates LL_DEBUGS() information at the top of these functions, but in a typical log file we wouldn't see the LL_DEBUGS() message. Eliminate a few catch (std::exception e) clauses: the information we get from boost::current_exception_diagnostic_information() in a catch (...) clause makes it unnecessary to distinguish. In a few cases, add a final 'throw;' to a catch (...) clause: having logged the local context info, propagate the exception to be caught by higher-level try/catch. In a couple places, couldn't resist reconciling indentation within a particular function: tabs where the rest of the function uses tabs, spaces where the rest of the function uses spaces. In LLLogin::Impl::loginCoro(), eliminate some confusing comments about an array of rewritten URIs that date back to a long-deleted implementation.

2015-07-10MAINT-5351: Improve management of "current" coroutine information.Nat Goodspeed
Our first cut at tracking the "current" coroutine simply reset the pointer to NULL every time we context-switched away. But that strategy doesn't handle the case of coroutine A launching coroutine B. Introduce LLCoros::CoroData to track, among other things, the previous value of the current-coroutine pointer each time we switch into a coroutine. Restore THAT value when we switch back out.

2015-07-02MAINT-5357: Introduce and populate llcoro:: namespace.Nat Goodspeed
To date, the coroutine helper functions in lleventcoro.h have been in the global namespace. Migrate them into llcoro namespace, and fix references. Specifically, LLVoidListener => llcoro::VoidListener, and voidlistener(), postAndWait(), both waitForEventOn(), postAndWait2(), errorException() and errorLog() have been moved into llcoro. Also migrate new LLCoros::get_self() and Suspending to llcoro:: namespace. While at it, I realized that -- having converted several lleventcoro.h functions from templates (for arbitrary 'self' parameter type) to ordinary functions, having moved them from lleventcoro.h to lleventcoro.cpp, we can now migrate their helpers from lleventcoro.h to lleventcoro.cpp as well. This eliminates the need for the LLEventDetail namespace; the relevant helpers are now in an anonymous namespace in the .cpp file: listenerNameForCoro(), storeToLLSDPath(), WaitForEventOnHelper and wfeoh().

2013-05-23MAINT-2724: Make viewer explicitly set coroutine stack size.Nat Goodspeed
Introduce LLCoros::setStackSize(), with a compile-time default value we hope we never have to use. Make LLAppViewer call it with the value of the new settings variable CoroutineStackSize as soon as we've read settings files. (While we're at it, notify interested parties that we've read settings files.) Give CoroutineStackSize a default value four times the previous default stack size. Make LLCoros::launch() pass the saved stack size to each new coroutine instance. Re-enable lleventcoro integration test. Use LLSDMap() construct rather than LLSD::insert(), which used to return the modified object but is now void.

2013-02-21MAINT-2389: Change viewer to Boost package without ucontext.h.Nat Goodspeed
In autobuild.xml, specify today's build of the Boost package that includes the Boost.Context library, and whose boost::dcoroutines library uses Boost.Context exclusively instead of its previous context-switching underpinnings (source of the ucontext.h dependency). Add BOOST_CONTEXT_LIBRARY to Boost.cmake and Copy3rdPartyLibs.cmake. Link it with the viewer and with the lllogin.cpp test executable. Track new Boost package convention that our (early, unofficial) Boost.Coroutine library is now accessed as boost/dcoroutine/etc.h and boost::dcoroutines::etc. Remove #include <boost/coroutine/coroutine.hpp> from llviewerprecompiledheaders.h and lllogin.cpp: old rule that Boost.Coroutine header must be #included before anything else that might use ucontext.h is gone now that we no longer depend on ucontext.h. In fact remove -D_XOPEN_SOURCE in 00-Common.cmake because that was inserted specifically to work around a known problem with the ucontext.h facilities.

2009-06-04DEV-32777: Use a canonical boost::coroutines::coroutine signature, relying onNat Goodspeed
boost::bind() to pass any other coroutine arguments. This allows us to remove the LLCoroBase and LLCoro constructs, directly storing a coroutine object in our ptr_map. It also allows us to remove the multiple launch() overloads for multiple arguments. Finally, it lets us move most launch() functionality into a non-template method.
2009-06-03DEV-32777: Introduce LLCoros, an LLSingleton registry of named coroutineNat Goodspeed
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().
