From 4d10172d8b2c72fa809e322a3b4ff326b19ff340 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Thu, 18 Aug 2016 17:33:44 -0400 Subject: MAINT-5011: Catch unhandled exceptions in LLCoros coroutines. 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. --- indra/newview/llappcorehttp.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'indra/newview/llappcorehttp.cpp') diff --git a/indra/newview/llappcorehttp.cpp b/indra/newview/llappcorehttp.cpp index 7ec041c02e..c1f898284a 100644 --- a/indra/newview/llappcorehttp.cpp +++ b/indra/newview/llappcorehttp.cpp @@ -31,6 +31,7 @@ #include "llappviewer.h" #include "llviewercontrol.h" #include "llexception.h" +#include "stringize.h" #include #include @@ -552,7 +553,7 @@ LLCore::HttpStatus LLAppCoreHttp::sslVerify(const std::string &url, } catch (...) { - LOG_UNHANDLED_EXCEPTION(); + LOG_UNHANDLED_EXCEPTION(STRINGIZE("('" << url << "')")); // any other odd error, we just handle as a connect error. result = LLCore::HttpStatus(LLCore::HttpStatus::EXT_CURL_EASY, CURLE_SSL_CONNECT_ERROR); } -- cgit v1.2.3
