2 | Name: Memoize | |
3 | What: Transparently speed up functions by caching return values. | |
4 | Version: 1.00 | |

9 | How to build me: | |
10 | ||
11 | perl Makefile.PL | |
12 | make | |
13 | make test | |
14 | ||
15 | There's a very small chance that the tests in speed.t and | |
16 | expire_module_t.t might fail because of clock skew or bizarre system | |
17 | load conditions. If the tests there fail, rerun them and see if the | |
18 | problem persists. | |
19 | ||
20 | If the tests work, | |
21 | ||
22 | make install | |
23 | ||
24 | If not, please send me a report that mentions which tests failed. | |
25 | The address is: mjd-perl-memoize+@plover.com. | |

37 | 0.62 was the fist version that would be distributed with Perl. | |
38 | I got so absorbed in integrating it that I wrote some tests | |
39 | that used Time::HiRes. I knew this was safe because | |
40 | Time::HiRes is also distributed with the same versions of | |
41 | Perl. I totally forgot that some people will get the module | |
42 | off of CPAN without Perl and they may not have TIme::HiRes. | |
43 | Sorry! | |

53 | ** The TIE option is now strongly deprecated. It will be ** | |
54 | ** permanently removed in the NEXT release of Memoize. ** | |
55 | ** Please convert all extant software to use HASH instead. ** | |
56 | ** ** | |
57 | ** See the manual for details. ** | |

61 | I'm sorry about this. I hate making incompatible changes. But as of | |
62 | v0.65, Memoize is included in the Perl core. It is about to become | |
63 | much more difficult to make incompatible interface changes; if I don't | |
64 | get rid of TIE now, I may not get another chance. | |
65 | ||
66 | TIE presented serious problems. First, it had a bizarre syntax. But | |
67 | the big problem was that it was difficult and complicated for | |
68 | expiration manager authors to support; evern expiration manager had to | |
69 | duplicate the logic for handling TIE. HASH is much simpler to use, | |
70 | more powerful, and is trivial for expiration managers to support. | |
71 | ||
72 | Many long-awaited cleanups and bug fixes. | |
73 | ||
74 | Memoize now works under threaded perl | |
75 | ||
76 | Slow tests speeded up. More test file improvements. | |
77 | ||
78 | Long-standing LIST_CACHE bug cleared up---it turns out that there | |
79 | never was a bug. I put in tests for it anyway. | |
80 | ||
81 | Manual increased. | |
