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.
Sometimes it can be useful to have http_proxy set in the environment, but if
we leave it set while INTEGRATION_TEST_llcorehttp is running, the test hangs.
Suppress that variable for that integration test.
This exception class got inadvertently swept up into the llcoro namespace. Its
LLClassConvention name is intended for use in the global namespace. As there
are no current references, this is a trivial change.
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().
Both BOOST_CONTEXT_LIBRARY and BOOST_COROUTINE_LIBRARY were mentioned. But as
BOOST_COROUTINE_LIBRARY depends on BOOST_CONTEXT_LIBRARY, they must be
mentioned in that order for Linux to successfully link the test programs.
Each test<n>() method invokes a function from earlier in the source. It's much
better if each of those functions immediately precedes the test that invokes it.
