README DB_File::Lock version 0.01 by David Harris WHAT DOES THIS MODULE DO? This module provides a wrapper for the DB_File module, adding locking. This is useful for applications which need to have concurrent access to a DB_File for two reasons: (1) you may want to save writing out the actual flock call before tie and after untie which gets old quickly. (2) you may be running in an enviornment such as mod_perl where the un-flocking of the lockfile must be handled by the DESTROY/untie mechanism to prevent a dropped lock. (see: http://perl.apache.org/guide/dbm.html#mod_perl_and_dbm) INSTALL To install the module, do the usual: perl Makefile.PL make make test (optionally set TEST_VERBOSE=1 or VERY_VERBOSE=1) make install The test files in this module require a valid fork command. If your platform does not have fork(2), then please disable testing when installing this module. ___________________ Copyright (c) 1999-2000 David R. Harris. All rights reserved.
