* bpo-36670, regrtest: Fix WindowsLoadTracker() for partial line (GH-16550) WindowsLoadTracker.read_output() now uses a short buffer for incomplete line. (cherry picked from commit3e04cd268e) * bpo-36670: Enhance regrtest WindowsLoadTracker (GH-16553) The last line is now passed to the parser even if it does not end with a newline, but only if it's a valid value. (cherry picked from commitc65119d5bf) * bpo-36670: Enhance regrtest (GH-16556) * Add log() method: add timestamp and load average prefixes to main messages. * WindowsLoadTracker: * LOAD_FACTOR_1 is now computed using SAMPLING_INTERVAL * Initialize the load to the arithmetic mean of the first 5 values of the Processor Queue Length value (so over 5 seconds), rather than 0.0. * Handle BrokenPipeError and when typeperf exit. * format_duration(1.5) now returns '1.5 sec', rather than '1 sec 500 ms' (cherry picked from commit098e25672f)
