Write messages when debugging which do not interfere with stdout. Useful in tests, which monitor stdout and would break with unexpected output. Trace messages can go to the console (which is opened as a file), or to a disk file; the tracefile argument persists across calls unless overridden. Args: tracefile: file to write trace message to. If omitted, write to the previous trace file (default: console). mode: file open mode (default: 'w') tstamp: write relative timestamps with trace. Outputs time since scons was started, and time since last trace (default: False) cSs |dS)N)close)ZtraceFPr r r trace_cleanupszTrace..trace_cleanupNz%8.4f %8.4f: ) TraceDefaultTimeStampDefaultTraceFPrBr(atexitregister TypeErrortime perf_counterr StartTime PreviousTimeflush)msgZ tracefilemodeZtstamprVfpZnowr r r Traces*  re)N)r)r)r)NrTF)&__doc__rZrNsysr]rrZtrack_instancesrrrrstdoutrr!r%platformr,ZSCons.compat.win32r/r1 ImportErrorr:r?rArDrHrKrQrOr6rYrWrXr^r_r`rer r r r s\
