Under debug LL_ERRS will show a message as well, but release won't show anything and will quit silently so show a notification when applicable.

2020-03-25DRTVWR-476: On Windows, use prebuilt Boost.Stacktrace.Nat Goodspeed
2020-03-25DRTVWR-476: Enrich LLExceptions thrown by LLTHROW() with stack trace.Nat Goodspeed
The LLTHROW() abstraction allows us to enrich the subject exception with a boost::stacktrace -- without having to propagate the boost/stacktrace.hpp header throughout the code base. To my delight, our existing use of boost::current_exception_diagnostic_information() already reports the newly added boost::stacktrace information -- we don't have to query it specifically!
2016-09-02MAINT-5011: Abbreviate __FILE__ path in log_unhandled_exception_().Nat Goodspeed
LLError::abbreviateFile() is specifically to avoid cluttering log output with the prefix of an absolute file path on the original build system, pointless for anyone trying to read the log.
2016-09-01MAINT-5011: Use LL_VLOGS() rather than raw lllog() macro.Nat Goodspeed
Raw lllog() doesn't work for varying log level, which is why LL_VLOGS() exists.
2016-08-31MAINT-5011: Add log tag to LOG_UNHANDLED_EXCEPTION() log messages.Nat Goodspeed
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.
2016-08-17MAINT-5011: Add llexception_test.cpp with tests (and conclusions).Nat Goodspeed
llexception_test.cpp is an unusual test source in that it need not be verified on every build, so its invocation in indra/llcommon/CMakeLists.txt is commented out with that remark. Its purpose is to help a developer decide what base class(es) to use for LLException, how to throw and how to catch. Our current conclusions are written up as comments in llexception_test.cpp. Added CRASH_ON_UNHANDLED_EXCEPTION() and LOG_UNHANDLED_EXCEPTION() macros to llexception.h -- macros to log __FILE__, __LINE__ and __PRETTY_FUNCTION__ of the catch site. These invoke functions in llexception.cpp so we don't need to #include llerror.h for every possible catch site.
