The timeline is output to a file, either stderr or the * value of the environment variable NS_TIMELINE_LOG_FILE. On the * Mac, the timeline is output to the file named "timeline.txt". The * reason it's different on the Mac is that the Mac environment * initialization code happens after timeline initialization code. * * If NS_TIMELINE_INIT_TIME is set in the environment, that will be * used as the time of startup; otherwise the current time when mark() * is first called will be used. * * mark() is used to put marks on the timeline. * * indent() and outdent() are used to format the timeline a bit to * show nesting. This doesn't produce perfect results in the face of * asychrony and multiple threads. * * enter() and leave() are convenience functions that add marks to the * timeline and do indentation. * * startTimer() and stopTimer() control named stop watches. If * startTimer() is called more than once, an equal number of * stopTimer() calls are needed to actually stop the timer. This * makes these timers slightly useful in a threaded environment. * * markTimer() puts a mark on the timeline containing the total for * the named timer. * * Don't use nsITimelineService in C++ code; use the NS_TIMELINE * macros instead. nsITimelineService exists so that JavaScript code * can mark the timeline. */ [scriptable, uuid(93276790-3daf-11d5-b67d-000064657374)] interface nsITimelineService : nsISupports { /** * mark() * Print ": \n" in the timeline log file. */ void mark(in string text); /** * causes subsequent marks to be indented for a more readable * report. */ void indent(); /** * Causes subsequent marks to be outdented. */ void outdent(); /** * enter/leave bracket code with "..." and "..." as * well as indentation. */ void enter(in string text); void leave(in string text); void startTimer(in string timerName); void stopTimer(in string timerName); void markTimer(in string timerName); }; %{C++ #endif /* MOZ_TIMELINE */ %} %{C++ #ifdef MOZ_TIMELINE /* * These are equivalent to the corresponding nsITimelineService * methods, and can be called before XPCOM is initialized. */ PR_EXTERN(nsresult) NS_TimelineMark(const char *text, ...); PR_EXTERN(nsresult) NS_TimelineStartTimer(const char *timerName); PR_EXTERN(nsresult) NS_TimelineStopTimer(const char *timerName); PR_EXTERN(nsresult) NS_TimelineMarkTimer(const char *timerName); PR_EXTERN(nsresult) NS_TimelineIndent(); PR_EXTERN(nsresult) NS_TimelineOutdent(); PR_EXTERN(nsresult) NS_TimelineEnter(const char *text); PR_EXTERN(nsresult) NS_TimelineLeave(const char *text); /* * Use these macros for the above calls so we can easily compile them * out. */ #define NS_TIMELINE_MARK(text) NS_TimelineMark(text) #define NS_TIMELINE_MARKV(args) NS_TimelineMark args #define NS_TIMELINE_INDENT() NS_TimelineIndent() #define NS_TIMELINE_OUTDENT() NS_TimelineOutdent() #define NS_TIMELINE_ENTER(text) NS_TimelineEnter(text) #define NS_TIMELINE_LEAVE(text) NS_TimelineLeave(text) #define NS_TIMELINE_START_TIMER(timerName) NS_TimelineStartTimer(timerName) #define NS_TIMELINE_STOP_TIMER(timerName) NS_TimelineStopTimer(timerName) #define NS_TIMELINE_MARK_TIMER(timerName) NS_TimelineMarkTimer(timerName) /* * NS_TIMELINE_MARK_ macros for various data types.
