| 17:36 | Update requirement marks due to changes in documentation wording. (check-in: 326cdc16f4 user: drh tags: trunk) | |
| 16:33 | Allow compile-time options -DHAVE_GETHOSTUUID=0 and -DHAVE_GETHOSTUUID=1. (check-in: 3bcb9cc104 user: drh tags: trunk) | |
| 15:15 | Alternative implementation of the previous check-in which is testable. (check-in: 102ef64462 user: drh tags: trunk) | |
| 15:01 | Fix sqlite3ExprCompare() so that it ignores differences in the Expr.iTable field for IN operators, as otherwise it can lead to false negatives, which is usually harmless, but can cause problems for an assert() in the window function logic. (check-in: 6a204b192a user: drh tags: trunk) | |

| 23:57 | Small performance optimization in the JSON parser of Geopoly. (check-in: fb520e7103 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: dc35f7b175 user: drh tags: trunk) | |
| 20:20 | • Fixed ticket [69d642332d]: The typeof() and length() functions fail in some virtual tables. plus 5 other changes (artifact: 8d26e66af7 user: drh) | |
| 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: 322ab1fc61 user: drh tags: trunk) | |
| 20:04 | • New ticket [69d642332d] The typeof() and length() functions fail in some virtual tables.. (artifact: 43a256c6a1 user: drh) | |
| 17:33 | Another minor tweak to memstat.c so that it may be built against older versions of SQLite. (check-in: 4c1fed60b9 user: dan tags: trunk) | |
| 17:15 | Modify the memstat virtual table so that it works with SQLite version 3.9.2. (check-in: 7171d8ae6b user: drh tags: trunk) | |
| 17:03 | Add the sqlite_memstat extension - an eponymous virtual table that shows memory usages statistics for SQLite. (check-in: 954ef61f6a 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: 9351135b43 user: drh tags: memstat-vtab) | |
| 15:45 | Add initial ZIPVFS support for the "main" database to the sqlite_memstat virtual table. (check-in: 9cd27350b0 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: 64db614edd user: drh tags: immutable-pager) | |

| 21:09 | Add assert() statements that fail when a shallow copy is accessed after the original has been modified. These assert() statements should detect the kinds of subtle SCopy bugs such as caused the fault in ticket [b351d95f9cd5ef17e9d9dbae18f]. (check-in: 8b8e1732e8 user: drh tags: bug-b351d95f9c) | |
