http://bugzilla.moblin.org/show_bug.cgi?id=8264 Summary: improved logging via libsynthesis Classification: Moblin Projects Product: SyncEvolution Version: upstream Platform: Netbook OS/Version: Moblin Linux Status: ASSIGNED Severity: normal Priority: P2 Component: *Feature Request AssignedTo: syncevolution(a)lists.intel.com ReportedBy: patrick.ohly(a)intel.com CC: syncevolution(a)lists.intel.com There is a tentative new libsynthesis API call which allows users to pass more information into the logging: /** * @param aFile source file name from which log entry comes * @param aLine source file line * @param aFunction function name * @param aDbgLevel same bit mask as in the internal TDebugLogger; * currently DBG_HOT and DBG_ERROR are defined publicly * @param aLinePrefix a short string to be displayed in front of each line; * the advantage of passing this separately instead of * making it a part of aText is that the logger might * be able to insert the prefix more efficiently and/or * (depending on the log format) with extra formatting * @param aText the text to be printed, may consist of multiple lines; * the log always starts a new line after the text, regardless * of how many newlines might be at the end of the text */ void SySyncDebugPuts(void* aCB, cAppCharP aFile, int aLine, cAppCharP aFunction, int aDbgLevel, cAppCharP aLinePrefix, cAppCharP aText); It is tentative because: 1. it has to be called directly instead of via the SDK function tables, forcing users to link against libsynthesis 2. it's implementation and the underlying logging facilities in libsynthesis are incomplete: file/line/function and prefix are discarded Because of 1, linking in SyncEvolution 1.x dev branch failed when enabling shared libraries. This patch here solved this. It should be reverted once point 1 gets fixed: diff --git a/configure-pre.in b/configure-pre.in index 41f32ac..daf86c8 100644 --- a/configure-pre.in +++ b/configure-pre.in @@ -438,8 +438,12 @@ elif test "$enable_shared" = "no"; then SYNTHESIS_ENGINE="$SYNTHESIS_LIBS -lsynthesis" else # link against SDK alone, except in client-test - PKG_CHECK_MODULES(SYNTHESIS, "synthesis-sdk") - SYNTHESIS_ENGINE="`echo $SYNTHESIS_LIBS | sed -e 's/-lsynthesisstubs/-lsynthesis/'`" + #PKG_CHECK_MODULES(SYNTHESIS, "synthesis-sdk") + #SYNTHESIS_ENGINE="`echo $SYNTHESIS_LIBS | sed -e 's/-lsynthesisstubs/-lsynthesis/'`" + + # can't use the SDK alone because of sysync::SySyncDebugPuts() + PKG_CHECK_MODULES(SYNTHESIS, "synthesis") + SYNTHESIS_ENGINE="$SYNTHESIS_LIBS" fi if test $SYNTHESIS_SRC != "no-synthesis-source"; then @@ -459,7 +463,11 @@ if test $SYNTHESIS_SRC != "no-synthesis-source"; then case $SYNCML_ENGINES in both|client|server) SYNTHESIS_LIBS="$SYNTHESIS_LIBS $SYNTHESIS_SUBDIR/s AC_DEFINE(ENABLE_SYNCML_LINKED, 1, [SyncML engines are linked directly]) else - SYNTHESIS_LIBS="$SYNTHESIS_LIBS $SYNTHESIS_SUBDIR/src/libsynthesisstubs.la" + # It would be nice if we could avoid linking against libsynthesis.la here. + # This doesn't work at the moment because sysync::SySyncDebugPuts() + # is called directly by the libsynthesissdk instead of going through + # the normal C function pointer lookup. + SYNTHESIS_LIBS="$SYNTHESIS_LIBS $SYNTHESIS_SUBDIR/src/libsynthesis.la" fi SYNTHESIS_DEP=$SYNTHESIS_LIBS Point 2 is more involved. We are using the HTML log format. A good representation of the additional information must be found. Perhaps make it so that the source information is shown in a box when moving the mouse over a specific line? The prefix could be inserted before each line so that it is visible. -- Configure bugmail: http://bugzilla.moblin.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
