21<li>When doing DELETE and UPDATE, the library used to write the record
22 numbers of records to be deleted or updated into a temporary file.
23 This is changed so that the record numbers are held in memory.</li>
24<li>The DELETE command without a WHILE clause just removes the database
25 files from the disk, rather than going through and deleting record
26 by record.</li>

30<li>A serious bug fixed on Windows. Windows users should upgrade.
31 No impact to Unix.</li>

35<li>Modify the test scripts to identify tests that depend on system
36 load and processor speed and
37 to warn the user that a failure of one of those (rare) tests does
38 not necessarily mean the library is malfunctioning. No changes to
39 code.
40 </li>

44<li>Fix a bug which was causing
drhb8525d92001-03-14 12:54:11 +0000[diff] [blame]45 the UPDATE command to fail on systems where "malloc(0)" returns
drhb0729502001-03-14 12:35:57 +0000[diff] [blame]46 NULL. The problem does not appear Windows, Linux, or HPUX but does
47 cause the library to fail on QNX.
48 </li>

52<li>An unrelated (and minor) bug from Mark Muranwski fixed. The algorithm
53 for figuring out where to put temporary files for a "memory:" database
54 was not working quite right.
55 </li>

65 some terms that could be satisfied using indices and other terms that
66 could not. Fixed.</li>

70<li>Merge development changes into the main trunk. Future work toward
71 using a BTree file structure will use a separate CVS source tree. This
72 CVS tree will continue to support the GDBM version of SQLite only.</li>

99<li>Some sanity checking code was removed from the inner loop of vdbe.c

101 removed if you compile with -DNDEBUG.</li>

319and '_' wildcards of SQL.</li>
320<li>Added the <B>COPY</b> command patterned after
