Rotating files will break the follow method

[maxcountryman]

Just so you're aware, due to the way Python's file handler works, an open file which is rotated will break your follow loop. I had this problem in an application I wrote recently. As far as I know, there's no simple fix for it. In fact I had to do some nasty hacking which involved triggering a SIGHUP and catching it in the application then handling the reloading of the file. If you're curious check out logmon: https://github.com/maxcountryman/logmon (see the bottom of the README).

I need rotating files support too.

@BrunoQC you can easily build it in. See my instructions in the logmon README.

IMHO, the best way to avoid locking is to just write a wrapper of unixutils tail on windows and tail on posix platforms.

I've been using unixutils tail for about 10 years and its never failed me.

FYI - Found bugs with unixutils tail and found a way to extract the binaries from cygwin for standalone use (no install required). I also wrote a wrapper for this so one can process in python:
