Forget any cached value for script. If clustering is enabled, flush the caches on all servers in the cluster.

Parameters:

script (required)

The Tcl script whose cached value should be flushed.

Testcases:

No testcase defined.

Loop through all cached entries, flushing all that match the regular expression that was passed in. It is recommended to use util_memoize_flush_pattern whenever possible, since glob-match is in most cases sufficient and much better performance-wise. the glob match can be better supported by the built-in set of the server.

Switches:

-log (optional, boolean)

Whether to log keys checked and flushed (useful for debugging).

Parameters:

expr (required)

The regular expression to match.

Testcases:

util_memoize_cache_flush

Return 1 if the util_memoize cache has been initialized and is ready to be used and 0 otherwise. util_memoize has now a failsafe mechanism when invoked before the cache is there.
