2013-07-03
| ||
| 19:53 | Experimental change to the handling of foreign key constraint violations when applying a changeset: all foreign keys, immediate and deferred, are deferred until the end of the transaction (or sub-transaction) opened by the sqlite3changeset_apply(). A single call to the conflict-handler (if any) is made if any FK constraint violations are still present in the database at this point.

| 19:41 | Allow read transactions to be freely opened and closed by SQL statements run from within the implementation of user-functions if the user-function is called by a SELECT statement that does not access any database tables (e.g. "SELECT user_function();"). (check-in: f308c48517 user: dan tags: trunk) | |
| 17:29 | Add a bit to the SQLITE_TESTCTRL_OPTIMIZATIONS option for sqlite3_file_control() that will disable the use of SQLITE_STAT3 information in the query planner. (check-in: 60c19b8679 user: drh tags: trunk) | |

|
2013-06-26

| 02:15 | Only eliminate inner loops of a JOIN if they are the RHS of a LEFT JOIN and if they give no more than a single result. This appears to give correct answers in all cases. (check-in: d7a25cc797 user: drh tags: omit-join-table-opt) | |
| 02:05 | Attempt to disable inner loops of a join that do not generate output. This does not work, since the inner loops might run zero times and thus inhibit all output.

| 16:19 | Minor performance tuning of the NGQP. (check-in: cbef38c2d1 user: drh tags: nextgen-query-plan-exp) | |
| 16:17 | Up until now the fts4 "unicode61" tokenizer has treated all private use codepoints except the first and last of each of the three ranges as alphanumeric (eligible to be part of tokens). This commit fixes this so that all private use codepoints are considered alphanumeric. In other words, it fixes the handling of codepoints 0xE000, 0xF8FF, 0xF0000, 0xFFFFD, 0x100000 and 0x10FFFD.

| 19:28 | The expected result in a test case can be of the form "*glob*" or "~*glob*" to match or not match the GLOB pattern.
