| 22 | test scripts. This function is not useful for anything other than |
| 23 | testing and debugging, as far as I know.</li> |
| drh | 61fc2c6 | 2000-06-12 12:29:25 +0000 | [diff] [blame^] | 24 | <li>Added a few more tests that take advantage of the new fcnt() function. |
| 25 | The new tests did not uncover any new problems.</li> |

| 51 | <li>All database files to be modified by an UPDATE, INSERT or DELETE are |
| 52 | now locked before any changes are made to any files. |
| 53 | This makes it safe (I think) to access |
| 54 | the same database simultaneously from multiple processes.</li> |

| 60 | (or threads) |
| 61 | can access the same database simultaneously. More work needed in |
| 62 | this area, though.</li> |

| 73 | <li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B> |
| 74 | but it uses Unix shell globbing wildcards instead of the '%' |
| 75 | and '_' wildcards of SQL.</li> |
| 76 | <li>Added the <B>COPY</b> command patterned after |
| 77 | <a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite |
| 78 | can now read the output of the <b>pg_dump</b> database dump utility |
| 79 | of PostgreSQL.</li> |
| 80 | <li>Added a <B>VACUUM</B> command that that calls the |
