4633a7c4 LW |
16 | 0.1 - Initial Release |
17 | 0.2 - No longer bombs out if dbopen returns an error. | |
18 | 0.3 - Added some support for multiple btree compares | |
19 | 1.0 - Complete support for multiple callbacks added. | |
20 | Fixed a problem with pushing a value onto an empty list. | |
21 | 1.01 - Fixed a SunOS core dump problem. | |
22 | The return value from TIEHASH wasn't set to NULL when | |
23 | dbopen returned an error. | |
88108326 | 24 | 1.02 - Use ALIAS to define TIEARRAY. |
25 | Removed some redundant commented code. | |
26 | Merged OS2 code into the main distribution. | |
27 | Allow negative subscripts with RECNO interface. | |
28 | Changed the default flags to O_CREAT|O_RDWR | |
f6b705ef | 29 | 1.03 - Added EXISTS |
610ab055 PM |
30 | 1.04 - fixed a couple of bugs in hash_cb. Patches supplied by |
31 | Dave Hammen, hammen@gothamcity.jsc.nasa.gov | |
32 | 1.05 - Added logic to allow prefix & hash types to be specified via | |
33 | Makefile.PL | |
ff68c719 | 34 | 1.06 - Minor namespace cleanup: Localized PrintBtree. |
36477c24 | 35 | 1.07 - Fixed bug with RECNO, where bval wasn't defaulting to "\n". |

18d2dc8c | 37 | 1.09 - Default mode for dbopen changed to 0666 |
a0b8c8c1 PM |
38 | 1.10 - Fixed fd method so that it still returns -1 for |
39 | in-memory files when db 1.86 is used. | |

68dc0745 | 41 | 1.12 - No change to DB_File.xs |
1f70e1ea PM |
42 | 1.13 - Tidied up a few casts. |

44 | database and an ordinary array to a HASH or BTREE database. | |
45 | 1.50 - Make work with both DB 1.x or DB 2.x | |
46 | 1.51 - Fixed a bug in mapping 1.x O_RDONLY flag to 2.x DB_RDONLY equivalent | |
