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

|
|
record.

|
|
|
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

|
|
Create fixed-length intermediate records past "end" of DB
|
|

|
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.

|
|
Support 64K pages.
|
|
btree/hash/recno:
