drhe91cd0c2000-06-12 12:36:36 +0000[diff] [blame]167<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
168 returns the number of database "Fetch" operations that have occurred.
169 This function is designed for use in test scripts to verify that
170 queries are efficient and appropriately optimized. Fcnt() has no other
171 useful purpose, as far as I know.</li>
172<li>Added a bunch more tests that take advantage of the new fcnt() function.
drh61fc2c62000-06-12 12:29:25 +0000[diff] [blame]173 The new tests did not uncover any new problems.</li>

199<li>All database files to be modified by an UPDATE, INSERT or DELETE are
200now locked before any changes are made to any files.
201This makes it safe (I think) to access
202the same database simultaneously from multiple processes.</li>
203<li>The code appears stable so we are now calling it "beta".</li>
204}
205
206chng {2000 June 1} {
207<li>Better support for file locking so that two or more processes
208(or threads)
209can access the same database simultaneously. More work needed in
210this area, though.</li>

220<li>Added the <b>LIKE</b> operator.</li>
221<li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B>
222but it uses Unix shell globbing wildcards instead of the '%'
223and '_' wildcards of SQL.</li>
224<li>Added the <B>COPY</b> command patterned after
225<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
226can now read the output of the <b>pg_dump</b> database dump utility
227of PostgreSQL.</li>
228<li>Added a <B>VACUUM</B> command that that calls the
229<b>gdbm_reorganize()</b> function on the underlying database
230files.</li>
231<li>And many, many bug fixes...</li>
