| ||
| 15:50 | Add the geopoly_group_bbox() aggregate function to the Geopoly module. (check-in: 2d4debcc user: drh tags: trunk) | |
|
2018-08-28
| ||
| 21:12 | Disable the server1.test script on old PPC Macs due to problems in the pthreads implementation on those archaic machines. (check-in: 43efdd8c user: drh tags: trunk) | |
| 19:23 | Stricter enforcement of the JSON and GeoJSON standards in the Geopoly extension. (check-in: c0bf3ff3 user: drh tags: trunk) | |

|
2018-08-27
| ||
| 17:13 | Add support for the Geopoly extension to the R-Tree extension. This also involves adding the SQLITE_INDEX_CONSTRAINT_FUNCTION capability to the xFindFunction method of the sqlite3_module object, and to the sqlite3_index_info.aConstraint.op field in the xBestIndex implementation of virtual tables. (check-in: 666133e3 user: drh tags: trunk) | |
| 17:05 | Minor changes to the visual01.txt test script. (Closed-Leaf check-in: 4bc28eed user: drh tags: rtree-geopoly) | |
| 15:55 | Split the three-argument version of geopoly_within() off into a separate function named geopoly_contains_point(). (check-in: 5a0e1541 user: drh tags: rtree-geopoly) | |
|
2018-08-25
| ||
| 23:03 | Enhance the geopoly virtual table so that it does a better job of optimizing geopoly_within() queries. (check-in: 1f717385 user: drh tags: rtree-geopoly) | |
| 19:51 | Provide the two-argument geopoly_within(P1,P2) routine that determines if polygon P2 is contained within polygon P1. Make this function available to the query planner for optimized rtree lookups. Update the visual01.txt script to verify that the new functionality actually works. (check-in: 6eb5d09b user: drh tags: rtree-geopoly) | |
| 18:57 | Fix a harmless compiler warning. (check-in: d49be983 user: drh tags: rtree-geopoly) | |
|
2018-08-24
| ||
| 19:04 | Set SQLITE_PTRSIZE to 4 when compiling with xlc on 32-bit AIX. (check-in: d158e5b1 user: mistachkin tags: trunk) | |
|
2018-08-23
| ||
| 18:56 | Automatically detect when compiling for AArch64 on windows and set SQLITE_BYTEORDER to little-endian to avoid compile-time testing. (check-in: ef6729be user: drh tags: trunk) | |
| 14:54 | Merge enhancements from trunk. (check-in: c446c884 user: drh tags: rtree-geopoly) | |
|
2018-08-21
| ||
| 17:03 | Fix a test case that was failing for SQLITE_ENABLE_STAT4 builds. (check-in: 1e29fd43 user: dan tags: trunk) | |
| 12:46 | Further attempts to reduce the number of false-positives genenerated by static analysis tools. (check-in: 38f9ce65 user: drh tags: trunk) | |
| 12:16 | Fix various harmless warnings generated by static analysis tools. (check-in: a04a0ea9 user: drh tags: trunk) | |
|
2018-08-17
| ||
| 21:14 | Fix harmless compiler warnings only seen with STAT4 enabled. (check-in: 6f5e84ba user: mistachkin tags: trunk) | |
|
2018-08-16
| ||
| 16:24 | Fix a harmless unused-variable compiler warning that only came up in certain compile-time configurations. (check-in: 45684292 user: drh tags: trunk) | |
| 15:29 | Fix EXPLAIN QUERY PLAN so that it describes IN operators implemented using a ROWID lookup. (check-in: 60045fbf user: drh tags: trunk) | |
|
2018-08-15
| ||
| 14:03 | Allow sqlite3_snapshot_open() to be called to change the snapshot after a read transaction is already open on database. (check-in: 41399169 user: dan tags: trunk) | |
|
2018-08-14
| ||
| 15:12 | Fix UPSERT so that it checks the target-constraint first and fires the DO UPDATE if that constraint is violated regardless of whether or not other constraints are in violation. This aligns SQLite behavior with what PostgreSQL does. Fix for ticket [908f001483982c43cdb476dfb590a1a]. (check-in: 529fb55e user: drh tags: trunk) | |
|
2018-08-13
| ||
| 22:50 | Stop requiring the global VFS mutex to access the unixInodeInfo.pUnused field. The unixInodeInfo mutex is sufficient. (check-in: e3ea43da user: drh tags: trunk) | |
| 20:46 | Take extra precautions to ensure access to unixInodeInfo.pUnused is protected by all necessary mutexes. (check-in: 8b1e0010 user: drh tags: trunk) | |
| 12:58 | Fix a heap-corruption causing race condition in os_unix.c that could occur when one thread wal opening a database file while another is unlocking the same file. Edit: Let's go in a slightly different direction with this fix. (Closed-Leaf check-in: 2447e0fd user: dan tags: unix-lock-fix-attempt) | |
| 11:32 | Fix an incorrect comment on the unix-nolock VFS object. No functional code changes. (check-in: 90f7c193 user: drh tags: trunk) | |

| 15:27 | Merge latest trunk changes with this branch. (check-in: c355a837 user: dan tags: alter-table-rename-column) | |
| 14:23 | Fix a problem with renaming columns on tables with REFERENCES clauses that specify a large number of columns. (check-in: d48f7bbd user: dan tags: alter-table-rename-column) | |
|
2018-08-09
| ||
| 21:45 | Fix the isLikeOrGlob() routine in the WHERE clause processing logic so that it avoids signed/unsigned character comparisons, as that can lead to an incorrect answer if the ESCAPE clause is an invalid UTF8 string. Problem found by OSSFuzz. (check-in: 4195a3f8 user: drh tags: trunk) | |
| 20:47 | Experimental implementation of ALTER TABLE ... RENAME COLUMN. Still buggy. (check-in: fa0fc01e user: dan tags: alter-table-rename-column) | |
| 18:36 | When a column must be a constant due to WHERE clause and the value of that column is being coded as a constant, make sure the affinity is correct. (check-in: 7404ea83 user: drh tags: trunk) | |
|
2018-08-08
| ||
| 20:46 | Minor style improvements. (check-in: 60bbca2b user: mistachkin tags: trunk) | |
|
2018-08-06
| ||
| 17:12 | Allow sqlite3_snapshot_open() to be called to change the snapshot after a read transaction is already open on database. (Closed-Leaf check-in: 051ac015 user: dan tags: exp-snapshot-open) | |
| 02:08 | Enhance the edit() function so that it converts text from \r\n back into \n only if the original unedited copy contained no \r\n values. (check-in: 20c995d3 user: drh tags: trunk) | |
| 01:39 | Add the --info option to the fuzzcheck test utility. (check-in: 1caaaaa7 user: drh tags: trunk) | |
