Member Function Documentation

DemangleSymbol()

static void nsTraceRefcnt::DemangleSymbol ( const char *  aSymbol, char *  aBuffer, int  aBufLen  )

static

DumpStatistics()

static nsresult nsTraceRefcnt::DumpStatistics ( StatisticsType  aType = ALL_STATS, FILE *  aOut = 0  )

static

ResetStatistics()

static void nsTraceRefcnt::ResetStatistics ( )

static

SetActivityIsLegal()

static void nsTraceRefcnt::SetActivityIsLegal ( bool  aLegal )

static

Tell nsTraceRefcnt whether refcounting, allocation, and destruction activity is legal.

This is used to trigger assertions for any such activity that occurs because of static constructors or destructors.

Shutdown()

static void nsTraceRefcnt::Shutdown ( )

static

WalkTheStack()

static void nsTraceRefcnt::WalkTheStack ( FILE *  aStream )

static

Referenced by MOZ_ReportAssertionFailure(), and MOZ_ReportCrash().

WalkTheStackCached()

static void nsTraceRefcnt::WalkTheStackCached ( FILE *  aStream )

static

This is a variant of |WalkTheStack| that uses |CodeAddressService| to cache the results of |NS_DescribeCodeAddress|.

If |WalkTheStackCached| is being called frequently, it will be a few orders of magnitude faster than |WalkTheStack|. However, the cache uses a lot of memory, which can cause OOM crashes. Therefore, this should only be used for things like refcount logging which walk the stack extremely frequently.
