1db2-alpha.0 -> db2-alpha.1 2 This fixes a number of bugs in the alpha release. 3 1. 64-bit functionality. The test suite now runs on alphas. 4 Memory leak fixed. 5 Pairs no longer disappear when pages are exactly full. 6 Flush meta-data correctly on sync. 71.86 -> db2-alpha.0 8 This is an interim release. We are in the process of 9 adding logging, locking, and transaction support to all 10 the db access methods. This will necessitate database 11 format changes, interface changes, and major upheaval. 12 In the meantime, this PRELIMINARY release is to correct 13 some known bugs in the hash pacakge.

This is a major 44 change, cursors and duplicate pages all had to be reworked. 45 Return to a fixed stack. 46 recno: Affected by cursor changes. New cursor structures should 47 permit multiple cursors in the future. 48 491.78 -> 1.79 Mon Jun 20 17:36:47 EDT 1994 50 all: Minor cleanups of 1.78 for porting reasons; only 51 major change was inlining check of NULL pointer 52 so that __fix_realloc goes away. 53 541.77 -> 1.78 Thu Jun 16 19:06:43 EDT 1994 55 all: Move "standard" size typedef's into db.h. 56 571.76 -> 1.77 Thu Jun 16 16:48:38 EDT 1994 58 hash: Delete __init_ routine, has special meaning to OSF 2.0. 59 601.74 -> 1.76 61 all: Finish up the port to the Alpha. 62 631.73 -> 1.74 64 recno: Don't put the record if rec_search fails, in rec_rdelete. 65 Create fixed-length intermediate records past "end" of DB 66 correctly. 67 Realloc bug when reading in fixed records. 68 all: First cut at port to Alpha (64-bit architecture) using 69 4.4BSD basic integral types typedef's. 70 Cast allocation pointers to shut up old compilers. 71 Rework PORT directory into OS/machine directories. 72 731.72 -> 1.73 74 btree: If enough duplicate records were inserted and then deleted 75 that internal pages had references to empty pages of the 76 duplicate keys, the search function ended up on the wrong 77 page. 78 791.7 -> 1.72 12 Oct 1993 80 hash: Support NET/2 hash formats. 81 821.7 -> 1.71 16 Sep 1993 83 btree/recno: 84 Fix bug in internal search routines that caused 85 return of invalid pointers. 86 871.6 -> 1.7 07 Sep 1993 88 hash: Fixed big key overflow bugs. 89 test: Portability hacks, rewrite test script, Makefile. 90 btree/recno: 91 Stop copying non-overflow key/data pairs. 92 PORT: Break PORT directory up into per architecture/OS 93 subdirectories. 94 951.5 -> 1.6 06 Jun 1993 96 hash: In PAIRFITS, the first comparison should look at (P)[2]. 97 The hash_realloc function was walking off the end of memory. 98 The overflow page number was wrong when bumping splitpoint. 99 1001.4 -> 1.5 23 May 1993 101 hash: Set hash default fill factor dynamically. 102 recno: Fixed bug in sorted page splits. 103 Add page size parameter support. 104 Allow recno to specify the name of the underlying btree; 105 used for vi recovery. 106 btree/recno: 107 Support 64K pages. 108 btree/hash/recno: 109 Provide access to an underlying file descriptor. 110 Change sync routines to take a flag argument, recno 111 uses this to sync out the underlying btree. 112 1131.3 -> 1.4 10 May 1993 114 recno: Delete the R_CURSORLOG flag from the recno interface. 115 Zero-length record fix for non-mmap reads. 116 Try and make SIZE_T_MAX test in open portable. 117 1181.2 -> 1.3 01 May 1993 119 btree: Ignore user byte-order setting when reading already 120 existing database.
