6.5 statcache -- An optimization of os.stat()
The statcache module provides a simple optimization to os.stat(): remembering the values of previous invocations.
The statcache module defines the following functions:
- This is the main module entry-point. Identical for os.stat(), except for remembering the result for future invocations of the function.
The rest of the functions are used to clear the cache, or parts of it.
- Clear the cache: forget all results of previous stat() calls.
-
Forget the result of
stat(path), if any.
-
Forget all results of
stat(path)for path starting with prefix.
-
Forget all results of
stat(path)for path a file in the directory prefix, includingstat(prefix).
- Similar to forget_prefix(), but for all path values not starting with prefix.
Example:
>>> import os, statcache
>>> statcache.stat('.')
(16893, 2049, 772, 18, 1000, 1000, 2048, 929609777, 929609777, 929609777)
>>> os.stat('.')
(16893, 2049, 772, 18, 1000, 1000, 2048, 929609777, 929609777, 929609777)
