# $NetBSD: changelog,v 1.2 1996/05/03 21:20:56 cgd Exp $
1.84 -> 1.85
recno: #ifdef out use of mmap, it's not portable enough.
1.83 -> 1.84 Thu Aug 18 15:46:07 EDT 1994
recno: Rework fixed-length records so that closing and reopening
the file now works. Pad short records on input. Never do
signed comparison in recno input reading functions.
1.82 -> 1.83 Tue Jul 26 15:33:44 EDT 1994
btree: Rework cursor deletion code yet again; bugs with
deleting empty pages that only contained the cursor
record.
1.81 -> 1.82 Sat Jul 16 11:01:50 EDT 1994
btree: Fix bugs introduced by new cursor/deletion code.
Replace return kbuf/dbuf with real DBT's.
1.80 -> 1.81
btree: Fix bugs introduced by new cursor/deletion code.
all: Add #defines for Purify.
1.79 -> 1.80 Wed Jul 13 22:41:54 EDT 1994
btree Change deletion to coalesce empty pages. This is a major
change, cursors and duplicate pages all had to be reworked.
Return to a fixed stack.
recno: Affected by cursor changes. New cursor structures should
permit multiple cursors in the future.
1.78 -> 1.79 Mon Jun 20 17:36:47 EDT 1994
all: Minor cleanups of 1.78 for porting reasons; only
major change was inlining check of NULL pointer
so that __fix_realloc goes away.
1.77 -> 1.78 Thu Jun 16 19:06:43 EDT 1994
all: Move "standard" size typedef's into db.h.
1.76 -> 1.77 Thu Jun 16 16:48:38 EDT 1994
hash: Delete __init_ routine, has special meaning to OSF 2.0.
1.74 -> 1.76
all: Finish up the port to the Alpha.
1.73 -> 1.74
recno: Don't put the record if rec_search fails, in rec_rdelete.
Create fixed-length intermediate records past "end" of DB
correctly.
Realloc bug when reading in fixed records.
all: First cut at port to Alpha (64-bit architecture) using
4.4BSD basic integral types typedef's.
Cast allocation pointers to shut up old compilers.
Rework PORT directory into OS/machine directories.
1.72 -> 1.73
btree: If enough duplicate records were inserted and then deleted
that internal pages had references to empty pages of the
duplicate keys, the search function ended up on the wrong
page.
1.7 -> 1.72 12 Oct 1993
hash: Support NET/2 hash formats.
1.7 -> 1.71 16 Sep 1993
btree/recno:
Fix bug in internal search routines that caused
return of invalid pointers.
1.6 -> 1.7 07 Sep 1993
hash: Fixed big key overflow bugs.
test: Portability hacks, rewrite test script, Makefile.
btree/recno:
Stop copying non-overflow key/data pairs.
PORT: Break PORT directory up into per architecture/OS
subdirectories.
1.5 -> 1.6 06 Jun 1993
hash: In PAIRFITS, the first comparison should look at (P)[2].
The hash_realloc function was walking off the end of memory.
The overflow page number was wrong when bumping splitpoint.
1.4 -> 1.5 23 May 1993
hash: Set hash default fill factor dynamically.
recno: Fixed bug in sorted page splits.
Add page size parameter support.
Allow recno to specify the name of the underlying btree;
used for vi recovery.
btree/recno:
Support 64K pages.
btree/hash/recno:
Provide access to an underlying file descriptor.
Change sync routines to take a flag argument, recno
uses this to sync out the underlying btree.
1.3 -> 1.4 10 May 1993
recno: Delete the R_CURSORLOG flag from the recno interface.
Zero-length record fix for non-mmap reads.
Try and make SIZE_T_MAX test in open portable.
1.2 -> 1.3 01 May 1993
btree: Ignore user byte-order setting when reading already
existing database. Fixes to byte-order conversions.
1.1 -> 1.2 15 Apr 1993
No bug fixes, only compatibility hacks.
