From 90a1b67cc43792e1ca0047eaca51530aa14e134c Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Thu, 9 Feb 2012 15:22:24 -0500 Subject: Remove LLJob class: apr_procattr_autokill_set() should now handle. LLJob was vestigial code from before migrating Job Object support into APR. Also add APR signal-name string to getStatusString() output. --- indra/llcommon/llprocess.cpp | 70 +++----------------------------------------- 1 file changed, 4 insertions(+), 66 deletions(-) diff --git a/indra/llcommon/llprocess.cpp b/indra/llcommon/llprocess.cpp index 1305c1d764..7ccbdeed01 100644 --- a/indra/llcommon/llprocess.cpp +++ b/indra/llcommon/llprocess.cpp @@ -31,6 +31,7 @@ #include "llstring.h" #include "stringize.h" #include "llapr.h" +#include "apr_signal.h" #include #include @@ -274,10 +275,10 @@ std::string LLProcess::getStatusString(const std::string& desc, const Status& st #if LL_WINDOWS return STRINGIZE(desc << " killed with exception " << std::hex << status.mData); #else - return STRINGIZE(desc << " killed by signal " << status.mData); + return STRINGIZE(desc << " killed by signal " << status.mData + << " (" << apr_signal_description_get(status.mData) << ")"); #endif - return STRINGIZE(desc << " in unknown state " << status.mState << " (" << status.mData << ")"); } @@ -391,72 +392,9 @@ std::ostream& operator<<(std::ostream& out, const LLProcess::Params& params) static std::string WindowsErrorString(const std::string& operation); -/** - * Wrap a Windows Job Object for use in managing child-process lifespan. - * - * On Windows, we use a Job Object to constrain the lifespan of any - * autokill=true child process to the viewer's own lifespan: - * http://stackoverflow.com/questions/53208/how-do-i-automatically-destroy-child-processes-in-windows - * (thanks Richard!). - * - * We manage it using an LLSingleton for a couple of reasons: - * - * # Lazy initialization: if some viewer session never launches a child - * process, we should never have to create a Job Object. - * # Cross-DLL support: be wary of C++ statics when multiple DLLs are - * involved. - */ -class LLJob: public LLSingleton -{ -public: - void assignProcess(const std::string& prog, LLProcess::handle hProcess) - { - // If we never managed to initialize this Job Object, can't use it -- - // but don't keep spamming the log, we already emitted warnings when - // we first tried to create. - if (! mJob) - return; - - if (!
