Finally, the future stable version will be v4.0.0 not v3.4.0 v3.3.16 changelog: Windows packages for v3.4.0beta_20170807_0320f9d5b5e are released. CAVEAT: The 32bit build doesn't work on Windows XP.
It's a pity Python doesn't have this facility built in as Py Qt is a huge dependency if all you're using is teh QFile System Watcher class. I wanted to point out that you'll need a QApplication instance for it to work, I added "app = Qt Gui. One that may not be the best way of doing it, but it sure is a short way.
QApplication(sys.argv)" right under the imports and then "app.exec_()" after the signal connections. ), but for unix user, you should use the "fcntl" system call. It's mostly the same code if you need to write it in C (same function names) import time import fcntl import os import signal FNAME = "/HOME/TOTO/FILETOWATCH" def handler(signum, frame): print "File %s modified" % (FNAME,) signal.signal(signal. Handy tool for restarting application when changes have been made to the source.
[Edit] I should have mentioned that I was after a solution that doesn't require polling. It seems this doesn't work over a mapped network drive. Only note: the example on their project page doesn't work out of the box. OS disk caching is very mature and Watchdog involves polling APIs anyhow.
I'm guessing windows doesn't 'hear' any updates to the file the way it does on a local disk. It's mainly for watching huge folder structures IMHO.import os class Monkey(object): def __init__(self): self._cached_stamp = 0 self.filename = '/path/to/file' def ook(self): stamp = os.stat(self.filename).st_mtime if stamp ! Same for me, works for directory only and watch files in this directory. FILE_FLAG_BACKUP_SEMANTICS, None ) # Open the file we're interested in a = open(file_to_watch, "r") # Throw away any exising log data a.read() # Wait for new data and call Process New Data for each new chunk that's written while 1: # Wait for a change to occur results = win32file.
