|
|
Arguments:
|
|
f1 -- First file name
|
|
f2 -- Second file name
|
|
shallow -- Just check stat signature (do not read the files).
|
defaults to 1.
|
|
Return value:
|
|
True if the files are the same, False otherwise.
|
|
This function uses a cache for past comparisons and the results,
|
with a cache invalidation mechanism relying on stale signatures.

|
|
dircmp(a,b,ignore=None,hide=None)
|
A and B are directories.
|
IGNORE is a list of names to ignore,
|
defaults to ['RCS', 'CVS', 'tags'].
|
HIDE is a list of names to hide,
|
defaults to [os.curdir, os.pardir].
|
|
High level usage:
|
x = dircmp(dir1, dir2)
|
x.report() -> prints a report on the differences between dir1 and dir2
|
or
|
x.report_partial_closure() -> prints report on differences between dir1
|
and dir2, and reports on common immediate subdirectories.
|
x.report_full_closure() -> like report_partial_closure,
|
but fully recursive.
|
|
Attributes:
|
left_list, right_list: The files in dir1 and dir2,
|
filtered by hide and ignore.
|
common: a list of names in both dir1 and dir2.
|
left_only, right_only: names only in dir1, dir2.
|
common_dirs: subdirectories in both dir1 and dir2.
|
common_files: files in both dir1 and dir2.
|
common_funny: names in both dir1 and dir2 where the type differs between
|
dir1 and dir2, or the name is not stat-able.
|
same_files: list of identical files.
|
diff_files: list of filenames which differ.
|
funny_files: list of files which could not be compared.
|
subdirs: a dictionary of dircmp objects, keyed by names in common_dirs.

|
|
a, b -- directory names
|
common -- list of file names found in both directories
|
shallow -- if true, do comparison based solely on stat() information
|
|
Returns a tuple of three lists:
|
files that compare equal
|
files that are different
|
filenames that aren't regular files.
