source code

Variables
	close_fds = `True`
	__package__ = `'trac.util'`

Imports: errno, math, os, time, cleandoc, des_crypt, crypt, all, any, frozenset, reversed, set, sorted, partial, md5, sha1, groupby, tee, OrderedDict

Function Details

wait_for_file_mtime_change(filename)

source code

This function is typically called before a file save operation, waiting if necessary for the file modification time to change. The purpose is to avoid successive file updates going undetected by the caching mechanism that depends on a change in the file modification time to know when the file should be reparsed.
