| 17:43 | Fix the build so that it works with -DSQLITE_TEST_REALLOC_STRESS Closed-Leaf check-in: 90ba2b2e5c user: drh tags: stmt-journal-testing | |
| 17:31 | When compiling with SQLITE_DEBUG, add run-time checks to ensure that no statement aborts unless either there have been no writes or else there is a statement journal. check-in: 5a4542dbcf user: drh tags: stmt-journal-testing | |
| 13:23 | Untested incremental check-in. Add the geopoly_xform() function. Complete basic logic for the geopoly virtual table. check-in: ed06cc3256 user: drh tags: rtree-geopoly | |
|
2018-05-26
| ||
| 21:17 | More fixes for different window frame types. check-in: 2c85668a0f user: dan tags: exp-window-functions | |
| 20:04 | Merge the ability to plan virtual table queries using overloaded functions. check-in: 2c2a202c14 user: drh tags: rtree-geopoly | |
| 18:03 | Experimental change that allows overloaded functions to be analyzed by the xBestIndex method and used by the xFilter method of a virtual table. Leaf check-in: a353b1d7ee user: drh tags: vtab-func-constraint | |
| 16:00 | Store application-defined function names as lower-case to avoid the need for case conversions before calling xFindFunction on virtual tables. Avoid using lookaside to store the destructors for application defined functions, as lookaside should be reserved for transient allocations. check-in: 777189ce88 user: drh tags: trunk | |
| 13:55 | Add a single sentence of documentation about the virtual table scan flags. No changes to code. check-in: 27b4fa5dd0 user: drh tags: trunk | |

| 22:39 | Untested incremental check-in. Basic infrastructure for geopoly in place, except for the MATCH operator. check-in: b27451910b user: drh tags: rtree-geopoly | |
| 20:53 | Incremental check-in: Progress toward implementing the geopoly vtab. check-in: 9b7d6f986a user: drh tags: rtree-geopoly | |
| 20:30 | Fix "RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING" window frame processing. check-in: b4e9c68669 user: dan tags: exp-window-functions | |
| 19:22 | Forward port the geopoly extension functions into the r-tree extension, with the idea of creating a new spatial index based on simply polygons. check-in: 0593aac88a user: drh tags: rtree-geopoly | |
| 14:39 | This is an untested proof-of-concept for enhancements to RTree that attempt to use sqlite3_value_nochange() to reduce the amount of work associated with UPDATE operations in cases where either the coordinates or the auxiliary data is unchanged. Leaf check-in: 6f7cfeff70 user: drh tags: rtree-update-optimization | |
| 09:36 | Merge latest trunk changes into this branch. check-in: 6232519899 user: dan tags: exp-window-functions | |
| 09:29 | Fixes for "ROWS BETWEEN <expr> FOLLOWING AND <expr> FOLLOWING" and "ROWS BETWEEN <expr> FOLLOWING AND UNBOUNDED FOLLOWING" check-in: 5ac44872fd user: dan tags: exp-window-functions | |
| 03:46 | Add SQLITE_LOCKED_VTAB and SQLITE_CORRUPT_SEQUENCE to sqlite3ErrName(). Also, use SQLITE_CORRUPT_BKPT in one more place. Leaf check-in: eac8888db3 user: mistachkin tags: errCodes | |

| 23:51 | When doing a one-pass UPDATE or DELETE on virtual tables, close the cursor prior to running VUpdate. This allows one-pass to work on virtual tables that do not allow concurrent reads and writes. Enhance rtree to take advantage of this new capability. check-in: b816023ce0 user: drh tags: trunk | |
| 22:42 | New test case for reading and writing the same rtree concurrently. check-in: 3ba08e53d5 user: drh tags: trunk | |
| 22:31 | Do not allow RTree writes when a read cursor is active on the same virtual table, as the writes might rebalance and disrupt the read cursors. Return the new SQLITE_LOCKED_VTAB error code if this happens. check-in: d4ce666108 user: drh tags: trunk | |
| 21:10 | Allow "<expr> PRECEDING" to be used to specify the end of a window frame. check-in: 7b709a989c user: dan tags: exp-window-functions | |
| 17:49 | Support other frame types that use "<expr> PRECEDING" or "<expr> FOLLOWING" as start or end conditions. check-in: ec7b648c7f user: dan tags: exp-window-functions | |
| 17:38 | In the OOM testing logic, add the sqlite3FirstFault() routine as a place to set a breakpoint the first time any simulated OOM fault occurs for a single test case. check-in: b4d80bd287 user: drh tags: trunk | |
| 17:25 | Fix a typo in a comment used to generate VDBE opcode documentation. No code changes. check-in: 36cdfbf2ce user: drh tags: trunk | |
| 16:18 | Addition cases for rtree preformance testing in speedtest1.c. Add the --nodiff option to the speed-check.sh script. check-in: 95f2d62cf3 user: drh tags: trunk | |
| 13:59 | Updates to the sqlite3_vtab_nochange() documentation. No changes to code. check-in: 5bd99abc10 user: drh tags: trunk | |

| 17:53 | Remove a branch that is no longer used due to the fix to the sqlite_sequence schema problem, ticket [d8dc2b3a58cd5dc2918a1d4acbba4676a23ada4c] check-in: 066742692a user: drh tags: trunk | |
| 16:50 | Verify that the sqlite_sequence table exists and is in approximately the correct format prior to using it to process an autoincrement table. Fix for ticket [d8dc2b3a58cd5dc2918a1d4a]. check-in: e199e859ac user: drh tags: trunk | |
