111<li>The file format for indices was changed slightly in order to work
112 around an inefficiency that can sometimes come up with GDBM when
113 there are large indices having many entries with the same key.

drhe91cd0c2000-06-12 12:36:36 +0000[diff] [blame]157<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
158 returns the number of database "Fetch" operations that have occurred.
159 This function is designed for use in test scripts to verify that
160 queries are efficient and appropriately optimized. Fcnt() has no other
161 useful purpose, as far as I know.</li>
162<li>Added a bunch more tests that take advantage of the new fcnt() function.
drh61fc2c62000-06-12 12:29:25 +0000[diff] [blame]163 The new tests did not uncover any new problems.</li>

drh37f0b252000-06-09 03:52:04 +0000[diff] [blame]173<li>Added compound select operators: <B>UNION</b>, <b>UNION ALL</B>,

189<li>All database files to be modified by an UPDATE, INSERT or DELETE are
190now locked before any changes are made to any files.
191This makes it safe (I think) to access
192the same database simultaneously from multiple processes.</li>
193<li>The code appears stable so we are now calling it "beta".</li>
194}
195
196chng {2000 June 1} {
197<li>Better support for file locking so that two or more processes
198(or threads)
199can access the same database simultaneously. More work needed in
200this area, though.</li>
201}

210<li>Added the <b>LIKE</b> operator.</li>
211<li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B>
212but it uses Unix shell globbing wildcards instead of the '%'
213and '_' wildcards of SQL.</li>
214<li>Added the <B>COPY</b> command patterned after
215<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
216can now read the output of the <b>pg_dump</b> database dump utility
217of PostgreSQL.</li>
218<li>Added a <B>VACUUM</B> command that that calls the
219<b>gdbm_reorganize()</b> function on the underlying database
220files.</li>
221<li>And many, many bug fixes...</li>
