2020-07-07DRTVWR-476, SL-13555: Don't crash if user closes viewer during login.Nat Goodspeed
Ever since February 2010, the body of the login coroutine function has been enclosed in try/catch (...), with an llerrs message to try to crash more informatively than the runtime's unhandled-exception termination. Over the years this evolved to LL_ERRS and then to CRASH_ON_UNHANDLED_EXCEPTION. This persisted despite the August 2016 addition of generic catch clauses in the LLCoros::toplevel() function to serve the same purpose, and despite the subsequent introduction of the LLCoros::Stop family of exceptions to deliberately throw into waiting coroutines on viewer shutdown. That's exactly what was happening. When the user closed the viewer while waiting for the response from login.cgi, the waiting operation threw LLCoros::Stopping, which was caught by that CRASH_ON_UNHANDLED_EXCEPTION, which crashed the viewer with LL_ERRS rather than propagating up to the toplevel() and cleanly terminating the coroutine. Change CRASH_ON_UNHANDLED_EXCEPTION() to LOG_UNHANDLED_EXCEPTION() and re-throw so toplevel() can handle.
2020-04-03DRTVWR-476: Make LoginListener::waitFor() take arbitrary predicate.Nat Goodspeed
This allows one of the tests to specifically waitFor() the completion status update from LLLogin, rather than the next status update to come along: the coroutine potentially emits a whole sequence of status updates before completion. Then the waitFor() overload that merely waits for the next status update is implemented by passing that specific predicate to the other overload.

2020-03-25DRTVWR-476, SL-12197: Don't throw Stopping from main coroutine.Nat Goodspeed
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.
2020-03-25DRTVWR-476: Infrastructure to help manage long-lived coroutines.Nat Goodspeed
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.
2020-03-25SL-1968: Extend lllogin_test login-failed cases for new sync timing.Nat Goodspeed
On login failure, LLLogin now tries to sync up with SLVersionChecker. It waits for up to 10 seconds before shrugging and giving up. Since that coroutine can now block for that long, make the llogin_test failure cases wait at least that long too.

2020-03-25SL-793: Fix lllogin_test.cpp for new LLCoros implementation.Nat Goodspeed
Delete the test for SRV timeout: lllogin no longer issues an SRV query. That test only confuses the test program without exercising any useful paths in production code. As with other tests dating from the previous LLCoros implementation, we need a few llcoro::suspend() calls sprinkled in so that a fiber marked ready -- by fulfilling the future for which it is waiting -- gets a chance to run. Clear LLEventPumps between test functions.
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).
2018-10-04DRTVWR-474: Make login coroutine sync with updater process on failure.Nat Goodspeed
Specifically, introduce an LLEventMailDrop("LoginSync"). When the updater detects that an update is required, it will post to that rendezvous point. When login.cgi responds with login failure, make the login coroutine wait (a few seconds) for that ping from the updater. If we receive that ping and if it contains a "reply" key, make the fail.login listener respond to the updater with an indication of whether to proceed with update. If both login.cgi and the updater concur that an update is required, produce a new confirmation message for the user and then (once user responds) tell the updater to proceed. Otherwise, produce the usual login-failure message and tell the updater never mind. Introduce LLCoro::OverrideConsuming to provide temporary save/restore of the set_consuming() / get_consuming() flag. It's a good idea to set the consuming flag when retrieving data from an LLEventMailDrop.
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.
2016-08-17MAINT-5011: Try to enrich catch (...) logging throughout viewer.Nat Goodspeed
Turns out we have a surprising number of catch (...) clauses in the viewer code base. If all we currently do is LL_ERRS() << "unknown exception" << LL_ENDL; then call CRASH_ON_UNHANDLED_EXCEPTION() instead. If what we do is LL_WARNS() << "unknown exception" << LL_ENDL; then call LOG_UNHANDLED_EXCEPTION() instead. Since many places need LOG_UNHANDLED_EXCEPTION() and nobody catches LLContinueError yet, eliminate LLContinueError& parameter from LOG_UNHANDLED_EXCEPTION(). This permits us to use the same log message as CRASH_ON_UNHANDLED_EXCEPTION(), just with a different severity level. Where a catch (...) clause actually provides contextual information, or makes an error string, add boost::current_exception_diagnostic_information() to try to figure out actual exception class and message.

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().
