From 993f54f6e91d78a9c2e1389ad878d6bd46e9be5b Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Wed, 17 Aug 2016 15:40:03 -0400 Subject: MAINT-5011: Try to enrich catch (...) logging throughout viewer. 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. --- indra/llmessage/llcoproceduremanager.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'indra/llmessage/llcoproceduremanager.cpp') diff --git a/indra/llmessage/llcoproceduremanager.cpp b/indra/llmessage/llcoproceduremanager.cpp index d4c0788b7d..4b1be5b0ff 100644 --- a/indra/llmessage/llcoproceduremanager.cpp +++ b/indra/llmessage/llcoproceduremanager.cpp @@ -28,6 +28,7 @@ #include "linden_common.h" #include "llcoproceduremanager.h" #include +#include //========================================================================= // Map of pool sizes for known pools @@ -395,7 +396,8 @@ void LLCoprocedurePool::coprocedureInvokerCoro(LLCoreHttpUtil::HttpCoroutineAdap } catch (...) { - LL_WARNS() << "A non std::exception was thrown from " << coproc->mName << " with id=" << coproc->mId << "." << " in pool \"" << mPoolName << "\"" << LL_ENDL; + LL_WARNS() << "A non std::exception was thrown from " << coproc->mName << " with id=" << coproc->mId << "." << " in pool \"" << mPoolName << "\"\n" + << boost::current_exception_diagnostic_information() << LL_ENDL; } LL_INFOS() << "Finished coprocedure(" << coproc->mName << ")" << " in pool \"" << mPoolName << "\"" << LL_ENDL; -- cgit v1.2.3 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/llmessage/llcoproceduremanager.cpp | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) (limited to 'indra/llmessage/llcoproceduremanager.cpp') diff --git a/indra/llmessage/llcoproceduremanager.cpp b/indra/llmessage/llcoproceduremanager.cpp index 4b1be5b0ff..74cdff2b00 100644 --- a/indra/llmessage/llcoproceduremanager.cpp +++ b/indra/llmessage/llcoproceduremanager.cpp @@ -27,8 +27,9 @@ #include "linden_common.h" #include "llcoproceduremanager.h" +#include "llexception.h" +#include "stringize.h" #include -#include //========================================================================= // Map of pool sizes for known pools @@ -389,15 +390,14 @@ void LLCoprocedurePool::coprocedureInvokerCoro(LLCoreHttpUtil::HttpCoroutineAdap { coproc->mProc(httpAdapter, coproc->mId); } - catch (std::exception &e) - { - LL_WARNS() << "Coprocedure(" << coproc->mName << ") id=" << coproc->mId.asString() << - " threw an exception!
