2021-05-12SL-10297: Get rid of LLError::LLCallStacks::allocateStackBuffer().Nat Goodspeed
Also freeStackBuffer() and all the funky classic-C string management of a big flat buffer divided into exactly 512 128-byte strings. Define StringVector as a std::vector<std::string>, and use that instead. Retain the behavior of clearing the vector if it exceeds 512 entries. This eliminates the LLError::Log::flush(const std::ostringstream&, char*) overload as well, with its baffling mix of std::string and classic-C (e.g. strlen(out.str().c_str()). If we absolutely MUST use a big memory pool for performance reasons, let's use StringVector with allocators.
2021-05-12SL-10297: Eliminate llerror.cpp's Globals::messageStream and bool.Nat Goodspeed
Instead of a single std::ostringstream instance shared by all callers, even those on different threads, make each of the relevant lllog_test_() and llcallstacks macros instantiate independent (stack) std::ostringstream objects. lllog_test_() is called by LL_DEBUGS(), LLINFOS(), LL_WARNS(), LL_ERRS(), LL_VLOGS() et al. Eliminate LLError::Log::out(), whose sole function was to arbitrate use of that shared std::ostringstream. Amusingly, if the lock couldn't be locked or if messageStreamInUse was set, out() would allocate a new (heap!) std::ostringstream anyway, which would then have to be freed by flush(). Make both LLError::Log::flush() overloads accept const std::ostringstream&. Make LL_ENDL pass the local _out instance. This eliminates the need to check whether the passed std::ostringstream* references the shared instance and (if so) reset it or (if not) delete it. Make LLError::LLCallStacks::insert() accept the local _out instance as non- const std::ostream&, rather than acquiring and returning std::ostringstream*. Make end() accept the local instance as const std::ostringstream&.
2021-05-11SL-10297: Move LL_ERRS crash location into the LL_ERRS macro itself.Nat Goodspeed
Introduce Oz's LLERROR_CRASH macro analogous to the old LLError::crashAndLoop() function. Change LL_ENDL macro so that, after calling flush(), if the CallSite is for LEVEL_ERROR, we invoke LLERROR_CRASH right there. Change the meaning of LLError::FatalFunction. It used to be responsible for the actual crash (hence crashAndLoop()). Now, instead, its role is to disrupt control flow in some other way if you DON'T want to crash: throw an exception, or call exit() or some such. Any FatalFunction that returns normally will fall into the new crash in LL_ENDL. Accordingly, the new default FatalFunction is a no-op lambda. This eliminates the need to test for empty (not set) FatalFunction in Log::flush(). Remove LLError::crashAndLoop() because the official LL_ERRS crash is now in LL_ENDL. One of the two common use cases for setFatalFunction() used to be to intercept control in the last moments before crashing -- not to crash or to avoid crashing, but to capture the LL_ERRS message in some way. Especially when that's temporary, though (e.g. LLLeap), saving and restoring the previous FatalFunction only works when the lifespans of the relevant objects are strictly LIFO. Either way, that's a misuse of FatalFunction. Fortunately the Recorder mechanism exactly addresses that case. Introduce a GenericRecorder template subclass, with LLError::addGenericRecorder(callable) that accepts a callable with suitable (level, message) signature, instantiates a GenericRecorder, adds it to the logging machinery and returns the RecorderPtr for possible later use with removeRecorder(). Change llappviewer.cpp's errorCallback() to an addGenericRecorder() callable. Its role was simply to update gDebugInfo["FatalMessage"] with the LL_ERRS message, then call writeDebugInfo(), before calling crashAndLoop() to finish crashing. Remove the crashAndLoop() call, retaining the gDebugInfo logic. Pass errorCallback() to LLError::addGenericRecorder() instead of setFatalFunction(). Oddly, errorCallback()'s crashAndLoop() call was conditional on a compile-time SHADER_CRASH_NONFATAL symbol. The new mechanism provides no way to support SHADER_CRASH_NONFATAL -- it is a Bad Idea to return normally from any LL_ERRS invocation! Rename LLLeapImpl::fatalFunction() to onError(). Instead of passing it to LLError::setFatalFunction(), pass it to addGenericRecorder(). Capture the returned RecorderPtr in mRecorder, replacing mPrevFatalFunction. Then ~LLLeapImpl() calls removeRecorder(mRecorder) instead of restoring mPrevFatalFunction (which, as noted above, was order-sensitive). Of course, every enabled Recorder is called with every log message. onError() and errorCallback() must specifically test for calls with LEVEL_ERROR. LLSingletonBase::logerrs() used to call LLError::getFatalFunction(), check the return and call it if non-empty, else call LLError::crashAndLoop(). Replace all that with LLERROR_CRASH. Remove from llappviewer.cpp the watchdog_llerrs_callback() and watchdog_killer_callback() functions. watchdog_killer_callback(), passed to Watchdog::init(), used to setFatalFunction(watchdog_llerrs_callback) and then invoke LL_ERRS() -- which seems a bit roundabout. watchdog_llerrs_callback(), in turn, replicated much of the logic in the primary errorCallback() function before replicating the crash from llwatchdog.cpp's default_killer_callback(). Instead, pass LLWatchdog::init() a lambda that invokes the LL_ERRS() message formerly found in watchdog_killer_callback(). It no longer needs to override FatalFunction with watchdog_llerrs_callback() because errorCallback() will still be called as a Recorder, obviating watchdog_llerrs_callback()'s first half; and LL_ENDL will handle the crash, obviating the second half. Remove from llappviewer.cpp the static fast_exit() function, which was simply an alias for _exit() acceptable to boost::bind(). Use a lambda directly calling _exit() instead of using boost::bind() at all. In the CaptureLog class in llcommon/tests/wrapllerrs.h, instead of statically referencing the wouldHaveCrashed() function from test.cpp, simply save and restore the current FatalFunction across the LLError::saveAndResetSettings() call. llerror_test.cpp calls setFatalFunction(fatalCall), where fatalCall() was a function that simply set a fatalWasCalled bool rather than actually crashing in any way. Of course, that implementation would now lead to crashing the test program. Make fatalCall() throw a new FatalWasCalled exception. Introduce a CATCH(LL_ERRS("tag"), "message") macro that expands to: LL_ERRS("tag") << "message" << LL_ENDL; within a try/catch block that catches FatalWasCalled and sets the same bool. Change all existing LL_ERRS() in llerror_test.cpp to corresponding CATCH() calls. In fact there's also an LL_DEBUGS(bad tag) invocation that exercises an LL_ERRS internal to llerror.cpp; wrap that too.
2020-05-14DRTVWR-476: Fix LLError::Log::classname(T*) template function.Nat Goodspeed
First, the signature classname(const T*) was wrong: that function could only accept a pointer to const T. The expression classname(someptr) where someptr was a pointer to non-const SomeType displayed "SomeType*" because it could only match classname(const T&), where T was SomeType*. classname(T* const) is what we should have written, meaning "const pointer to T" rather than "pointer to const T." Second, the previous implementation failed to handle the case in which the pointer was nullptr.

2020-03-25DRTVWR-476: Introduce LLStacktrace, a token to stream stack trace.Nat Goodspeed
LLStacktrace has no behavior except when you stream an instance to a std::ostream. Then it reports the current traceback at that point to the ostream. This bit of indirection is intended to avoid the boost/stacktrace.hpp header from being included everywhere.

2016-09-01MAINT-5232: Introduce LL_VLOGS() macro: log call with variable level.Nat Goodspeed
In some places we want to log the same information but with different severity depending on specifics. In other cases we need to test the availability of the logging subsystem before engaging it. LL_VLOGS() accepts an LLError::ELevel argument that can differ with each call, while retaining the desirable feature of deciding only once for each level.
