This module provides functions for performing simple, timestamp-based
dependency of files and groups of files; also, functions based entirely
on such timestamp dependency analysis.
-
Return true if source exists and is more recently modified than
target, or if source exists and target doesn't.
Return false if both exist and target is the same age or newer
than source.
Raise DistutilsFileError if source does not exist.
| newer_pairwise( |
sources, targets) |
-
Walk two filename lists in parallel, testing if each source is newer
than its corresponding target. Return a pair of lists (sources,
targets) where source is newer than target, according to the semantics
of newer()
| newer_group( |
sources, target[, missing='error']) |
-
Return true if target is out-of-date with respect to any file
listed in sources In other words, if target exists and is newer
than every file in sources, return false; otherwise return true.
missing controls what we do when a source file is missing; the
default (
'error') is to blow up with an OSError from
inside os.stat();
if it is 'ignore', we silently drop any missing source files; if it is
'newer', any missing source files make us assume that target is
out-of-date (this is handy in ``dry-run'' mode: it'll make you pretend to
carry out commands that wouldn't work because inputs are missing, but
that doesn't matter because you're not actually going to run the
commands).
Release 2.5a0, documentation updated on August 30, 2005.
