| 02:34 | Experimental code that tries to put the computation of subqueries inside a subroutine, and reuse that subroutine if the same subquery is evaluated more than once. Current code does not work for CHECK constraints. (check-in: 6c44838a user: drh tags: reuse-subqueries) | |
|
2018-12-23
| ||
| 21:27 | Split the code generation for the RHS of IN operators and for SELECT and EXISTS expressions into two separate subroutines, because there is now little commonality between those to functions. This is intended to help make the code easier to read and maintain. (check-in: 2b6494b1 user: drh tags: trunk) | |

| 00:34 | The OP_Eq and OP_Ne operators have a special P5 value SQLITE_NOTNULL that asserts that the values are not null. Except that is not always true for a corrupt database. Adjust the assert() and add a testcase() to make this point clear. (check-in: a3fdb2c7 user: drh tags: trunk) | |
|
2018-12-21
| ||
| 22:11 | Update the dbtotxt utility program so that it does not output characters that are special to TCL, thus making the output of dbtotxt easier to insert into test scripts. (check-in: 48438bb3 user: drh tags: trunk) | |
| 22:08 | Improved detection of shadow table corruption in RTREE. (check-in: b39bf435 user: drh tags: trunk) | |
| 20:18 | Add new sqlite3_prepare_v3() flag SQLITE_PREPARE_NO_VTAB, for preparing statements that are not allowed to use any virtual tables. Use this to prevent circular references in triggers on virtual table shadow tables from causing resource leaks. (check-in: da587d18 user: dan tags: trunk) | |
| 19:55 | Use SQLITE_PREPARE_NO_VTAB in rtree as well. (Closed-Leaf check-in: 82a2ae71 user: dan tags: prepare-no-vtab) | |

| 18:50 | The fts4umlaut.test module requires FTS5, so do not try to run it without that module. (check-in: dee3ae90 user: drh tags: trunk) | |
| 18:17 | Fix the node hash function in RTREE to ensure that it always returns a non-negative value. (check-in: 0bf4c70a user: drh tags: trunk) | |

| 02:29 | Fix a bug in the custom in-memory VFS used by fuzzcheck. This bug masks other bugs that should have caused some existing fuzzdata7.db entries to fail, and so this fix is initially on a branch until those other bugs can be repaired. (check-in: e0994e99 user: drh tags: fuzzcheck-fix) | |

| 20:58 | Merge latest trunk into this branch. (check-in: 86750c92 user: dan tags: begin-concurrent) | |
| 20:46 | Have sqlite3changegroup_output_strm() call its output function more regularly. (check-in: 8467c31a user: dan tags: trunk) | |
| 18:51 | Fix a bug in the sqlite_memstat virtual table that was causing it to report the amount of memory used as zero bytes. (check-in: 8a758a87 user: drh tags: trunk) | |
| 14:01 | Add the geopoly_regular(X,Y,R,N) function to the geopoly extension. (check-in: 4505bbae user: drh tags: trunk) | |
| 13:18 | Make most geopoly functions pure. (check-in: 944e167a user: drh tags: trunk) | |
| 00:16 | Rig geopoly to use sqlite3AtoF() if it is available, as that routine is much faster than atof(). (check-in: 470c6c07 user: drh tags: trunk) | |

| 23:57 | Small performance optimization in the JSON parser of Geopoly. (check-in: fb520e71 user: drh tags: trunk) | |
| 20:37 | Enhance the GeoPOLY extension so that it always stores its polygons in the binary format, which is faster and more compact. (check-in: dc35f7b1 user: drh tags: trunk) | |
| 20:20 | Ensure that the OP_VColumn opcode does set sqlite3_vtab_nochange() unless the OPFLAG_NOCHNG bit is set in P5. Fix for ticket [69d642332d25aa3b7315a6d385] (check-in: 322ab1fc user: drh tags: trunk) | |
| 17:33 | Another minor tweak to memstat.c so that it may be built against older versions of SQLite. (check-in: 4c1fed60 user: dan tags: trunk) | |
| 17:15 | Modify the memstat virtual table so that it works with SQLite version 3.9.2. (check-in: 7171d8ae user: drh tags: trunk) | |
| 17:03 | Add the sqlite_memstat extension - an eponymous virtual table that shows memory usages statistics for SQLite. (check-in: 954ef61f user: drh tags: trunk) | |
| 16:57 | Enhancements to sqlite_memstat: (1) Add an extra "schema" column to show the schema name for ZIPVFS stats. (2) Only show ZIPVFS stats to schema that use ZIPVFS (3) Put a NULL in unused columns of the output. (Closed-Leaf check-in: 9351135b user: drh tags: memstat-vtab) | |

| 15:21 | Initial prototype of a eponymous virtual table that accesses sqlite3_status64() and sqlite3_db_status(). (check-in: 0b44e1f6 user: drh tags: memstat-vtab) | |
| 14:24 | Minor enhancement to the pager so that it remembers if the underlying database files is immutable. (Leaf check-in: 64db614e user: drh tags: immutable-pager) | |
