From e04f9ef1093287155f1d0820bd63c4b3c6c5d3d2 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Tue, 14 Dec 2010 19:27:43 -0500 Subject: SWAT-352: when loading lleventhost, call apr_dso_error() function. In addition to its usual apr_sterror() function, APR defines a special function specifically for errors relating to the apr_dso_*() functions. Introduce ll_apr_warn_status() and ll_apr_assert_status() overloads accepting apr_dso_handle_t* to call apr_dso_error() as well as apr_strerror() and log its output. Use new ll_apr_warn_status() in LLAppViewer::loadEventHostModule() for apr_dso_load() and apr_dso_sym() calls. Instead of shorthand ll_apr_assert_status(), use with llassert_always() so check is still performed even in Release build. Add more lleventhost-related debugging output, e.g. full pathname of the DLL. On Mac and Linux, call 'file' command to report nature of the DLL too. --- indra/llcommon/llapr.cpp | 22 ++++++++++++++++++++-- indra/llcommon/llapr.h | 5 +++++ 2 files changed, 25 insertions(+), 2 deletions(-) (limited to 'indra/llcommon') diff --git a/indra/llcommon/llapr.cpp b/indra/llcommon/llapr.cpp index 66ec5bad2c..d1c44c9403 100644 --- a/indra/llcommon/llapr.cpp +++ b/indra/llcommon/llapr.cpp @@ -28,6 +28,7 @@ #include "linden_common.h" #include "llapr.h" +#include "apr_dso.h" apr_pool_t *gAPRPoolp = NULL; // Global APR memory pool LLVolatileAPRPool *LLAPRFile::sAPRFilePoolp = NULL ; //global volatile APR memory pool. @@ -279,14 +280,31 @@ bool ll_apr_warn_status(apr_status_t status) { if(APR_SUCCESS == status) return false; char buf[MAX_STRING]; /* Flawfinder: ignore */ - apr_strerror(status, buf, MAX_STRING); + apr_strerror(status, buf, sizeof(buf)); LL_WARNS("APR") << "APR: " << buf << LL_ENDL; return true; } +bool ll_apr_warn_status(apr_status_t status, apr_dso_handle_t *handle) +{ + bool result = ll_apr_warn_status(status); + // Despite observed truncation of actual Mac dylib load errors, increasing + // this buffer to more than MAX_STRING doesn't help: it appears that APR + // stores the output in a fixed 255-character internal buffer.
