notification of file truncate

[nishant.deshpande at gmail.com]

hi,

I am running ubuntu 7.1 (linux 2.6.22-12-generic)

i was trying to implement 'tail -f' (well tail -F actually but for
this example i think its not relevent) and one of the features which i
couldn't get in python was notification of truncation of a file.

i looked at the inotify (the pyinotify package) and then the linux
inotify functionality.

i don't see the truncation notification anywhere... yet tail -F
notifies that the file has been truncated and repositions its offset
at top of the file to print out the next lines.

can anyone shed some light on this? i guess i need to look at the bash
tail code..
