| 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().

| 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. Needs to be enhanced to work only for LEFT JOINs or when we know that the inner loop will always run at least once. check-in: ca839723 user: drh tags: omit-join-table-opt | |

| 22:08 | Remove more vestiges of sqlite_query_plan from the test cases. check-in: eb27086e user: drh tags: nextgen-query-plan-exp | |
| 21:25 | Adjust the xBestIndex methods on both the fuzzer and transitive_closure virtual tables so that an unused MATCH operator gets a really large cost. Remove ambiguities from the fuzzer test cases. check-in: e2c1af78 user: drh tags: nextgen-query-plan-exp | |
| 20:46 | Pull in recent trunk changes. Fix the ORDER BY optimizer so that it is better able to deal with COLLATE clauses. Clean up ambiguities in the descidx1.test script. check-in: 6bc71dfc user: drh tags: nextgen-query-plan-exp | |

| 19:17 | Do not use an index fullscan for an UPDATE or DELETE or if disabled by sqlite3_test_control() or sqlite3_config(). check-in: fabb2185 user: drh tags: nextgen-query-plan-exp | |

| 20:43 | The NGQP might not find a solution if INDEXED BY constraints on the query are set wrong. If that is the case, print a "no query solution" error and abort before trying to use the non-existant solution. check-in: 42511a7e user: drh tags: nextgen-query-plan-exp | |
| 20:28 | Do not search using ON clause constraints of LEFT JOINs to the right of the table. check-in: 723f901a user: drh tags: nextgen-query-plan-exp | |
| 20:00 | Make sure a unique cursor number is allocated for automatic indices. check-in: 433d1aec user: drh tags: nextgen-query-plan-exp | |
| 19:14 | Do not attempt to generate code in the NGQP if there have been prior errors, since with prior errors some of the expressions might not be fully named resolved. check-in: 665e4291 user: drh tags: nextgen-query-plan-exp | |
| 18:20 | Fix a problem with code generation on LEFT JOIN of tables without an index. check-in: 0b1bee92 user: drh tags: nextgen-query-plan-exp | |
| 18:13 | Another virtual table fix in NGQP. check-in: 2f2ce416 user: drh tags: nextgen-query-plan-exp | |
| 17:55 | Fix problems in the virtual table logic for NGQP. check-in: 23af28e2 user: drh tags: nextgen-query-plan-exp | |
| 15:50 | Remove the definitions of objects that are no longer used: WhereCost, WherePlan, and WhereBestIdx. check-in: 816f8add user: drh tags: nextgen-query-plan-exp | |
| 15:36 | Improved handling of errors when doing run-time loading of an SQLite shared-library into TCL. check-in: b3f23d18 user: drh tags: trunk | |
| 15:18 | Allow tracing of whereLoopInsert() when the 0x8 bit is set on ".wheretrace". Remove the use of sqlite_query_plan from where2.test. Fix a bug in the code generator for OR clause optimizations. check-in: 707f0323 user: drh tags: nextgen-query-plan-exp | |
| 14:31 | Enhance the shell to provide more flexibility when entering numeric arguments on dot-commands. In particular, allow hex arguments to .wheretrace. check-in: b9578c37 user: drh tags: nextgen-query-plan-exp | |

| 22:27 | Incremental check-in with various NGQP fixes. Many tests still fail. check-in: a51d8c92 user: drh tags: nextgen-query-plan-exp | |
| 19:29 | Futher simplifications to the NGQP. Fix some test cases to use EXPLAIN QUERY PLAN rather than the (now obsolete) sqlite_query_plan global variable. check-in: ae985db4 user: drh tags: nextgen-query-plan-exp | |
| 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. This is useful for matching EXPLAIN QUERY PLAN output that contains regular expression syntax characters like "?", "(", and ")". check-in: a3b4e261 user: drh tags: nextgen-query-plan-exp | |
| 17:43 | Cut over the NGQP query planner. Remove lots of legacy code. This check-in compiles but does not work. The test suite gets incorrect answers and crashes. check-in: 001539df user: drh tags: nextgen-query-plan-exp | |
