From c9fc4349b7d4ab1f5a7bfc0125014a96a07e51a3 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Tue, 11 May 2021 21:42:14 -0400 Subject: SL-10297: Move LL_ERRS crash location into the LL_ERRS macro itself. 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. --- indra/llcommon/llerror.cpp | 37 +++---------------- indra/llcommon/llerror.h | 22 +++++++++--- indra/llcommon/llerrorcontrol.h | 57 +++++++++++++++++++++++------ indra/llcommon/llleap.cpp | 48 ++++++++++++------------- indra/llcommon/llsingleton.cpp | 15 +------- indra/llcommon/tests/llerror_test.cpp | 58 +++++++++++++++++++----------- indra/llcommon/tests/wrapllerrs.h | 22 ++++++------ indra/newview/llappviewer.cpp | 67 +++++++++-------------------------- 8 files changed, 159 insertions(+), 167 deletions(-) (limited to 'indra') diff --git a/indra/llcommon/llerror.cpp b/indra/llcommon/llerror.cpp index f876b8ee4a..9d775dcef3 100644 --- a/indra/llcommon/llerror.cpp +++ b/indra/llcommon/llerror.cpp @@ -549,7 +549,7 @@ namespace LLError mFileLevelMap(), mTagLevelMap(), mUniqueLogMessages(), - mCrashFunction(NULL), + mCrashFunction([](const std::string&){}), mTimeFunction(NULL), mRecorders(), mShouldLogCallCounter(0) @@ -728,7 +728,6 @@ namespace LLError::setDefaultLevel(LLError::LEVEL_INFO); LLError::setAlwaysFlush(true); LLError::setEnabledLogTypesMask(0xFFFFFFFF); - LLError::setFatalFunction(LLError::crashAndLoop); LLError::setTimeFunction(LLError::utcTime); // log_to_stderr is only false in the unit and integration tests to keep builds quieter @@ -1436,7 +1435,7 @@ namespace LLError if (site.mPrintOnce) { - std::ostringstream message_stream; + std::ostringstream message_stream; std::map::iterator messageIter = s->mUniqueLogMessages.find(message); if (messageIter != s->mUniqueLogMessages.end()) @@ -1457,8 +1456,8 @@ namespace LLError message_stream << "ONCE: "; s->mUniqueLogMessages[message] = 1; } - message_stream << message; - message = message_stream.str(); + message_stream << message; + message = message_stream.str(); } writeToRecorders(site, message); @@ -1466,10 +1465,7 @@ namespace LLError if (site.mLevel == LEVEL_ERROR) { g->mFatalMessage = message; - if (s->mCrashFunction) - { - s->mCrashFunction(message); - } + s->mCrashFunction(message); } } } @@ -1533,29 +1529,6 @@ namespace LLError return s->mShouldLogCallCounter; } -#if LL_WINDOWS - // VC80 was optimizing the error away. - #pragma optimize("", off) -#endif - void crashAndLoop(const std::string& message) - { - // Now, we go kaboom! - int* make_me_crash = NULL; - - *make_me_crash = 0; - - while(true) - { - // Loop forever, in case the crash didn't work? - } - - // this is an attempt to let Coverity and other semantic scanners know that this function won't be returning ever. - exit(EXIT_FAILURE); - } -#if LL_WINDOWS - #pragma optimize("", on) -#endif - std::string utcTime() { time_t now = time(NULL); diff --git a/indra/llcommon/llerror.h b/indra/llcommon/llerror.h index ffaa464d77..f8c0d03aea 100644 --- a/indra/llcommon/llerror.h +++ b/indra/llcommon/llerror.h @@ -382,11 +382,23 @@ typedef LLError::NoClassInfo _LL_CLASS_TO_LOG; #define LL_NEWLINE '\n' -#define LL_ENDL \ - LLError::End(); \ - LLError::Log::flush(_out, _site); \ - } \ - } while(0) +// Use this only in LL_ERRS or in a place that LL_ERRS may not be used +#define LLERROR_CRASH \ +{ \ + int* make_me_crash = NULL;\ + *make_me_crash = 0; \ + exit(*make_me_crash); \ +} + +#define LL_ENDL \ + LLError::End(); \ + LLError::Log::flush(_out, _site); \ + if (_site.mLevel == LLError::LEVEL_ERROR) \ + { \ + LLERROR_CRASH \ + } \ + } \ + } while(0) // NEW Macros for debugging, allow the passing of a string tag diff --git a/indra/llcommon/llerrorcontrol.h b/indra/llcommon/llerrorcontrol.h index 25786d5457..e87bb7bf35 100644 --- a/indra/llcommon/llerrorcontrol.h +++ b/indra/llcommon/llerrorcontrol.h @@ -94,14 +94,16 @@ namespace LLError */ typedef boost::function FatalFunction; - LL_COMMON_API void crashAndLoop(const std::string& message); - // Default fatal function: access null pointer and loops forever LL_COMMON_API void setFatalFunction(const FatalFunction&); - // The fatal function will be called when an message of LEVEL_ERROR + // The fatal function will be called after an message of LEVEL_ERROR // is logged.
