    1 1.84 -> 1.85
    2         recno:  #ifdef out use of mmap, it's not portable enough.
    3 
    4 1.83 -> 1.84    Thu Aug 18 15:46:07 EDT 1994
    5         recno:  Rework fixed-length records so that closing and reopening
    6                 the file now works.  Pad short records on input.  Never do
    7                 signed comparison in recno input reading functions.
    8 
    9 1.82 -> 1.83    Tue Jul 26 15:33:44 EDT 1994
   10         btree:  Rework cursor deletion code yet again; bugs with
   11                 deleting empty pages that only contained the cursor
   12                 record.
   13 
   14 1.81 -> 1.82    Sat Jul 16 11:01:50 EDT 1994
   15         btree:  Fix bugs introduced by new cursor/deletion code.
   16                 Replace return kbuf/dbuf with real DBT's.
   17 
   18 1.80 -> 1.81
   19         btree:  Fix bugs introduced by new cursor/deletion code.
   20         all:    Add #defines for Purify.
   21 
   22 1.79 -> 1.80    Wed Jul 13 22:41:54 EDT 1994
   23         btree   Change deletion to coalesce empty pages.  This is a major
   24                 change, cursors and duplicate pages all had to be reworked.
   25                 Return to a fixed stack.
   26         recno:  Affected by cursor changes.  New cursor structures should
   27                 permit multiple cursors in the future.
   28 
   29 1.78 -> 1.79    Mon Jun 20 17:36:47 EDT 1994
   30         all:    Minor cleanups of 1.78 for porting reasons; only
   31                 major change was inlining check of NULL pointer
   32                 so that __fix_realloc goes away.
   33 
   34 1.77 -> 1.78    Thu Jun 16 19:06:43 EDT 1994
   35         all:    Move "standard" size typedef's into db.h.
   36 
   37 1.76 -> 1.77    Thu Jun 16 16:48:38 EDT 1994
   38         hash:   Delete __init_ routine, has special meaning to OSF 2.0.
   39 
   40 1.74 -> 1.76
   41         all:    Finish up the port to the Alpha.
   42 
   43 1.73 -> 1.74
   44         recno:  Don't put the record if rec_search fails, in rec_rdelete.
   45                 Create fixed-length intermediate records past "end" of DB
   46                 correctly.
   47                 Realloc bug when reading in fixed records.
   48         all:    First cut at port to Alpha (64-bit architecture) using
   49                 4.4BSD basic integral types typedef's.
   50                 Cast allocation pointers to shut up old compilers.
   51                 Rework PORT directory into OS/machine directories.
   52 
   53 1.72 -> 1.73
   54         btree:  If enough duplicate records were inserted and then deleted
   55                 that internal pages had references to empty pages of the
   56                 duplicate keys, the search function ended up on the wrong
   57                 page.
   58 
   59 1.7  -> 1.72    12 Oct 1993
   60         hash:   Support NET/2 hash formats.
   61 
   62 1.7  -> 1.71    16 Sep 1993
   63         btree/recno:
   64                 Fix bug in internal search routines that caused
   65                 return of invalid pointers.
   66 
   67 1.6  -> 1.7     07 Sep 1993
   68         hash:   Fixed big key overflow bugs.
   69         test:   Portability hacks, rewrite test script, Makefile.
   70         btree/recno:
   71                 Stop copying non-overflow key/data pairs.
   72         PORT:   Break PORT directory up into per architecture/OS
   73                 subdirectories.
   74 
   75 1.5  -> 1.6     06 Jun 1993
   76         hash:   In PAIRFITS, the first comparison should look at (P)[2].
   77                 The hash_realloc function was walking off the end of memory.
   78                 The overflow page number was wrong when bumping splitpoint.
   79 
   80 1.4  -> 1.5     23 May 1993
   81         hash:   Set hash default fill factor dynamically.
   82         recno:  Fixed bug in sorted page splits.
   83                 Add page size parameter support.
   84                 Allow recno to specify the name of the underlying btree;
   85                         used for vi recovery.
   86         btree/recno:
   87                 Support 64K pages.
   88         btree/hash/recno:
   89                 Provide access to an underlying file descriptor.
   90                 Change sync routines to take a flag argument, recno
   91                         uses this to sync out the underlying btree.
   92 
   93 1.3  -> 1.4     10 May 1993
   94         recno:  Delete the R_CURSORLOG flag from the recno interface.
   95                 Zero-length record fix for non-mmap reads.
   96                 Try and make SIZE_T_MAX test in open portable.
   97 
   98 1.2  -> 1.3     01 May 1993
   99         btree:  Ignore user byte-order setting when reading already
  100                 existing database.  Fixes to byte-order conversions.
  101 
  102 1.1  -> 1.2     15 Apr 1993
  103                 No bug fixes, only compatibility hacks.
