Name: Memoize What: Transparently speed up functions by caching return values. Version: 1.00 Author: Mark-Jason Dominus (mjd-perl-memoize+@plover.com) ################################################################ How to build me: perl Makefile.PL make make test There's a very small chance that the tests in speed.t and expire_module_t.t might fail because of clock skew or bizarre system load conditions. If the tests there fail, rerun them and see if the problem persists. If the tests work, make install If not, please send me a report that mentions which tests failed. The address is: mjd-perl-memoize+@plover.com. ################################################################ What's new since 0.66: Minor documentation and test changes only. ################################################################ What's new since 0.65: Test changes only. 0.62 was the fist version that would be distributed with Perl. I got so absorbed in integrating it that I wrote some tests that used Time::HiRes. I knew this was safe because Time::HiRes is also distributed with the same versions of Perl. I totally forgot that some people will get the module off of CPAN without Perl and they may not have TIme::HiRes. Sorry! ################################################################ What's new since 0.62: N O T I C E ! **************************************************************** ** ** ** The TIE option is now strongly deprecated. It will be ** ** permanently removed in the NEXT release of Memoize. ** ** Please convert all extant software to use HASH instead. ** ** ** ** See the manual for details. ** ** ** **************************************************************** I'm sorry about this. I hate making incompatible changes. But as of v0.65, Memoize is included in the Perl core. It is about to become much more difficult to make incompatible interface changes; if I don't get rid of TIE now, I may not get another chance. TIE presented serious problems. First, it had a bizarre syntax. But the big problem was that it was difficult and complicated for expiration manager authors to support; evern expiration manager had to duplicate the logic for handling TIE. HASH is much simpler to use, more powerful, and is trivial for expiration managers to support. Many long-awaited cleanups and bug fixes. Memoize now works under threaded perl Slow tests speeded up. More test file improvements. Long-standing LIST_CACHE bug cleared up---it turns out that there never was a bug. I put in tests for it anyway. Manual increased.
