From 63b393da31e9fb972428fe957a05955a3d903113 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Mon, 5 Mar 2012 18:49:27 -0500 Subject: Introduce (disabled) LLLeap debugging code to validate stdin writes. While debugging mysterious problem on Windows, one potential failure mode to rule out was the possibility that streaming std::ostringstream << LLSDNotationStreamer(large_LLSD) might itself cause trouble -- even before attempting to write to the LLProcess::WritePipe. The debugging code validated that the correct length is being reported, and that deserializing the resulting buffer produces equivalent LLSD. This code verified correct operation, and so has been disabled, as it's expensive at runtime. --- indra/llcommon/llleap.cpp | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) (limited to 'indra/llcommon') diff --git a/indra/llcommon/llleap.cpp b/indra/llcommon/llleap.cpp index 34f77c3f3a..034c809330 100644 --- a/indra/llcommon/llleap.cpp +++ b/indra/llcommon/llleap.cpp @@ -192,6 +192,31 @@ public: std::ostringstream buffer; buffer << LLSDNotationStreamer(packet); +/*==========================================================================*| + // DEBUGGING ONLY: don't copy str() if we can avoid it. + std::string strdata(buffer.str()); + if (std::size_t(buffer.tellp()) != strdata.length()) + { + LL_ERRS("LLLeap") << "tellp() -> " << buffer.tellp() << " != " + << "str().length() -> " << strdata.length() << LL_ENDL; + } + // DEBUGGING ONLY: reading back is terribly inefficient. + std::istringstream readback(strdata); + LLSD echo; + LLPointer parser(new LLSDNotationParser()); + S32 parse_status(parser->parse(readback, echo, strdata.length())); + if (parse_status == LLSDParser::PARSE_FAILURE) + { + LL_ERRS("LLLeap") << "LLSDNotationParser() cannot parse output of " + << "LLSDNotationStreamer()" << LL_ENDL; + } + if (! llsd_equals(echo, packet)) + { + LL_ERRS("LLLeap") << "LLSDNotationParser() produced different LLSD " + << "than passed to LLSDNotationStreamer()" << LL_ENDL; + } +|*==========================================================================*/ + LL_DEBUGS("EventHost") << "Sending: " << buffer.tellp() << ':'; std::string::size_type truncate(80); if (buffer.tellp() <= truncate) -- cgit v1.2.3
