21<li>Documentation updates</li>
22<li>Some sanity checking code was removed from the inner loop of vdbe.c

drh80afdca2000-08-22 13:27:22 +0000107}

drh353f57e2000-08-02 12:26:28 +0000139chng {2000 Aug 2} {
140<li>The file format for indices was changed slightly in order to work
141 around an inefficiency that can sometimes come up with GDBM when
142 there are large indices having many entries with the same key.
143 <font color="red">** Incompatible Change **</font></li>

159<li>Better labels on column names of the result.</li>
160}
161
drh2dfbbca2000-07-28 14:32:48 +0000162chng {2000 July 28} {
163<li>Added the <b>sqlite_busy_handler()</b>
164 and <b>sqlite_busy_timeout()</b> interface.</li>
165}
166
drh74c360e2000-06-23 19:16:23 +0000167chng {2000 June 23} {
168<li>Begin writing the <a href="vdbe.html">VDBE tutorial</a>.</li>
169}
170
drh1fd14a72000-06-21 14:00:39 +0000171chng {2000 June 21} {
172<li>Clean up comments and variable names. Changes to documentation.
173 No functional changes to the code.</li>
174}
175
drh6206d502000-06-19 19:09:08 +0000176chng {2000 June 19} {
drh7ed19902000-06-19 19:10:28 +0000177<li>Column names in UPDATE statements were case sensitive.

drhe91cd0c2000-06-12 12:36:36 +0000186<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
187 returns the number of database "Fetch" operations that have occurred.
188 This function is designed for use in test scripts to verify that
189 queries are efficient and appropriately optimized. Fcnt() has no other
190 useful purpose, as far as I know.</li>
191<li>Added a bunch more tests that take advantage of the new fcnt() function.
drh61fc2c62000-06-12 12:29:25 +0000192 The new tests did not uncover any new problems.</li>
drh6de4f4c2000-06-12 12:20:48 +0000193}

196<li>Added lots of new test cases</li>
197<li>Fix a few bugs discovered while adding test cases</li>
198<li>Begin adding lots of new documentation</li>
199}
200
drh49c87802000-06-06 18:24:42 +0000201chng {2000 June 6} {
drh37f0b252000-06-09 03:52:04 +0000202<li>Added compound select operators: <B>UNION</b>, <b>UNION ALL</B>,
drhf5005772000-06-06 22:19:00 +0000203<b>INTERSECT</b>, and <b>EXCEPT</b></li>

214improved tests.</li>

216
drhbed86902000-06-02 13:27:59 +0000217chng {2000 June 2} {
218<li>All database files to be modified by an UPDATE, INSERT or DELETE are
219now locked before any changes are made to any files.
220This makes it safe (I think) to access
221the same database simultaneously from multiple processes.</li>
222<li>The code appears stable so we are now calling it "beta".</li>
223}
224
225chng {2000 June 1} {
226<li>Better support for file locking so that two or more processes
227(or threads)
228can access the same database simultaneously. More work needed in
229this area, though.</li>
230}
231
drh7203e282000-05-31 15:35:42 +0000232chng {2000 May 31} {

drhdce2cbe2000-05-31 02:27:49 +0000238chng {2000 May 30} {
239<li>Added the <b>LIKE</b> operator.</li>
240<li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B>
241but it uses Unix shell globbing wildcards instead of the '%'
242and '_' wildcards of SQL.</li>
243<li>Added the <B>COPY</b> command patterned after
244<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
245can now read the output of the <b>pg_dump</b> database dump utility
246of PostgreSQL.</li>
247<li>Added a <B>VACUUM</B> command that that calls the
248<b>gdbm_reorganize()</b> function on the underlying database
249files.</li>
250<li>And many, many bug fixes...</li>
251}
