android - Python can not capture full adb logs -


what want achieve - running adb log (logs running), doing activity on android, stop/end log capture (ctrl+c), post processing of logs.

only issue face - can not capture full logcat log in file

import sys  import subprocess import time import ctypes  # start  print "test start" time.sleep(5)  # log capturing start, log not stop keep on running proc = subprocess.popen("adb logcat -v time",stdout=subprocess.pipe ) time.sleep(3) # runs while   print "calc start" time.sleep(5) #start test************************************  code testing    #ctrl c*************************************************  try:     ctypes.windll.kernel32.generateconsolectrlevent(0, 0)     proc.wait() except keyboardinterrupt:     print "ignoring ctrlc" print "still running"   #********************adb log saving******************  text = proc.stdout.read()  f = open('c:\python27\out_logs_dd\log.txt', 'w')  f.write(text)  open('c:\python27\out_logs_dd\log.txt', 'w') f:    f.write(text)  f.close()

when run code, running log size small. searched , came know "proc.communicate()"might solution. tried 'communicate' not solve issue. pointer pls.

replacing proc.stdout.read() proc.stdout.readline() solved me. stdout.read() reads until eof - slowing down speed drastically. similar question: communicate subprocess without waiting subprocess terminate on windows
