2020-03-25SL-793: Use Boost.Fiber instead of the "dcoroutine" library.Nat Goodspeed
Longtime fans will remember that the "dcoroutine" library is a Google Summer of Code project by Giovanni P. Deretta. He originally called it "Boost.Coroutine," and we originally added it to our 3p-boost autobuild package as such. But when the official Boost.Coroutine library came along (with a very different API), and we still needed the API of the GSoC project, we renamed the unofficial one "dcoroutine" to allow coexistence. The "dcoroutine" library had an internal low-level API more or less analogous to Boost.Context. We later introduced an implementation of that internal API based on Boost.Context, a step towards eliminating the GSoC code in favor of official, supported Boost code. However, recent versions of Boost.Context no longer support the API on which we built the shim for "dcoroutine." We started down the path of reimplementing that shim using the current Boost.Context API -- then realized that it's time to bite the bullet and replace the "dcoroutine" API with the Boost.Fiber API, which we've been itching to do for literally years now. Naturally, most of the heavy lifting is in llcoros.{h,cpp} and lleventcoro.{h,cpp} -- which is good: the LLCoros layer abstracts away most of the differences between "dcoroutine" and Boost.Fiber. The one feature Boost.Fiber does not provide is the ability to forcibly terminate some other fiber. Accordingly, disable LLCoros::kill() and LLCoprocedureManager::shutdown(). The only known shutdown() call was in LLCoprocedurePool's destructor. We also took the opportunity to remove postAndSuspend2() and its associated machinery: FutureListener2, LLErrorEvent, errorException(), errorLog(), LLCoroEventPumps. All that dual-LLEventPump stuff was introduced at a time when the Responder pattern was king, and we assumed we'd want to listen on one LLEventPump with the success handler and on another with the error handler. We have never actually used that in practice. Remove associated tests, of course. There is one other semantic difference that necessitates patching a number of tests: with "dcoroutine," fulfilling a future IMMEDIATELY resumes the waiting coroutine. With Boost.Fiber, fulfilling a future merely marks the fiber as ready to resume next time the scheduler gets around to it. To observe the test side effects, we've inserted a number of llcoro::suspend() calls -- also in the main loop. For a long time we retained a single unit test exercising the raw "dcoroutine" API. Remove that. Eliminate llcoro_get_id.{h,cpp}, which provided llcoro::get_id(), which was a hack to emulate fiber-local variables. Since Boost.Fiber has an actual API for that, remove the hack. In fact, use (new alias) LLCoros::local_ptr for LLSingleton's dependency tracking in place of llcoro::get_id(). In CMake land, replace BOOST_COROUTINE_LIBRARY with BOOST_FIBER_LIBRARY. We don't actually use the Boost.Coroutine for anything (though there exist plausible use cases).

2015-08-18MAINT-5506: Fix library delimiters for LL_TEST_ADDITIONAL_LIBRARIES.Nat Goodspeed
Recent cmake versions are unhappy with embedding spaces in the LL_TEST_ADDITIONAL_LIBRARIES property. Using semicolons to delimit libraries seems to make it better.

This addresses a Linux link failure due to the Linux linker making a single left-to-right pass through libraries.
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.

2011-05-05Remove Pth library from viewer build.Nat Goodspeed
This library was only needed on the Mac, and only with the OS X 10.4 SDK. As of October 2010, we no longer build the viewer with that SDK. The 10.5 SDK we're currently using directly supports the functionality for which we originally brought in Pth.
