| 17:11 | Ensure that FTS5 queries of the form "WHERE rowid BETWEEN ? AND ? AND tbl MATCH ? ORDER BY rank" do rowid filtering before sorting. (check-in: f1138a38bd user: dan tags: trunk) | |
|
2018-09-01
| ||
| 06:13 | Update test script snapshot_fault.test to account for the new sqlite3_snapshot_open() error code. (check-in: c1aca7673a user: dan tags: trunk) | |
|
2018-08-31
| ||
| 23:22 | New hyperlink on the README.md file. (check-in: c663961e34 user: drh tags: trunk) | |
| 19:00 | If a call to sqlite3_snapshot_open() fails because the requested snapshot no longer exists, return SQLITE_ERROR_SNAPSHOT instead of SQLITE_BUSY_SNAPSHOT. (check-in: e07923128b user: dan tags: trunk) | |

| 20:28 | Try to identify the places in WAL code where thread-safety depends on the underlying architecture supporting atomic load and store of aligned 32-bit values. (check-in: 47d44be4a6 user: drh tags: trunk) | |
| 18:53 | Give the debugging routine print_pager_stats() external linkage in order to suppress harmless compiler and TSAN warnings. (check-in: ff4dc08298 user: drh tags: trunk) | |
| 01:52 | Improved JSON parser caching. (check-in: 58078c0d26 user: drh tags: trunk) | |

| 21:01 | Additional test cases for geopoly. (check-in: 19b5eb45e0 user: drh tags: trunk) | |
| 20:52 | Fixes to the UPDATE logic in Geopoly. (check-in: 7c3cee0a2a user: drh tags: trunk) | |
| 20:24 | Also free up the MEM_RowSet bit in the Mem.flags field and have RowSet objects be destroyed using Mem.xDel. This change results in faster code. (check-in: f48e9feb3f user: drh tags: trunk) | |
| 18:47 | Free up the MEM_Frame bit in Mem.flags object. Store VdbeFrame objects as MEM_Blob with a special Mem.xDel pointer instead. (check-in: 62db5fd476 user: drh tags: trunk) | |
| 15:50 | Add the geopoly_group_bbox() aggregate function to the Geopoly module. (check-in: 2d4debccbc 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: 43efdd8c7e user: drh tags: trunk) | |
| 19:23 | Stricter enforcement of the JSON and GeoJSON standards in the Geopoly extension. (check-in: c0bf3ff3af user: drh tags: trunk) | |
| 15:51 | Fix new issues in the geopoly module discovered by TH3. (check-in: 22fff9afc2 user: drh tags: trunk) | |
| 11:23 | Fix a problem causing spurious SQLITE_CORRUPT errors when using the snapshot API to read from old database snapshots. (check-in: 535155be58 user: dan 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: 666133e32c user: drh tags: trunk) | |
| 17:05 | Minor changes to the visual01.txt test script. (Closed-Leaf check-in: 4bc28eed32 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: 5a0e154103 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: 1f71738534 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: 6eb5d09b7f user: drh tags: rtree-geopoly) | |
| 18:57 | Fix a harmless compiler warning. (check-in: d49be9838d 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: d158e5b12e 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: ef6729be85 user: drh tags: trunk) | |
| 14:54 | Merge enhancements from trunk. (check-in: c446c88411 user: drh tags: rtree-geopoly) | |
|
2018-08-21
| ||
| 17:03 | Fix a test case that was failing for SQLITE_ENABLE_STAT4 builds. (check-in: 1e29fd430d user: dan tags: trunk) | |
| 12:46 | Further attempts to reduce the number of false-positives genenerated by static analysis tools. (check-in: 38f9ce6503 user: drh tags: trunk) | |
| 12:16 | Fix various harmless warnings generated by static analysis tools. (check-in: a04a0ea9e3 user: drh tags: trunk) | |
|
2018-08-17
| ||
| 21:14 | Fix harmless compiler warnings only seen with STAT4 enabled. (check-in: 6f5e84bafc 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: 456842924b user: drh tags: trunk) | |
| 15:29 | Fix EXPLAIN QUERY PLAN so that it describes IN operators implemented using a ROWID lookup. (check-in: 60045fbf52 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: 4139916995 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: 529fb55e3d user: drh tags: trunk) | |
|

| ||
| 22:50 | Stop requiring the global VFS mutex to access the unixInodeInfo.pUnused field. The unixInodeInfo mutex is sufficient. (check-in: e3ea43dabf user: drh tags: trunk) | |
| 20:46 | Take extra precautions to ensure access to unixInodeInfo.pUnused is protected by all necessary mutexes. (check-in: 8b1e0010b9 user: drh tags: trunk) | |
| 11:32 | Fix an incorrect comment on the unix-nolock VFS object. No functional code changes. (check-in: 90f7c193b4 user: drh tags: trunk) | |
|
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: 4195a3f8b5 user: drh tags: trunk) | |
| 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: 7404ea8316 user: drh tags: trunk) | |
|
2018-08-08
| ||
| 20:46 | Minor style improvements. (check-in: 60bbca2b9a 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: 051ac01520 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: 20c995d3f0 user: drh tags: trunk) | |
| 01:39 | Add the --info option to the fuzzcheck test utility. (check-in: 1caaaaa70f user: drh tags: trunk) | |
| 01:21 | Fix an overzealous assert() statement discovered by OSSFuzz. (check-in: d9c9fe9f5a user: drh tags: trunk) | |
|

| 20:30 | Remove the column-cache from the code generator. The column-cache has been a persistent source of bugs for years and with recent improvements in the performance of OP_Column, it no longer provides a benefit. After the column cache is removed, the binary is almost 2KB smaller and the speed-check.sh performance test is over 3 million cycles faster. (check-in: cdff3af7be user: drh tags: trunk) | |
| 20:12 | Remove a testcase() that is no longer reachable without the column cache. Provide an assert() to help prove that the testcase is no longer reachable. (Closed-Leaf check-in: a500893b6f user: drh tags: omit-column-cache) | |
| 17:15 | Fix comments that were made obsolete by the removal of the column cache. (check-in: 2041231d56 user: drh tags: omit-column-cache) | |
| 16:54 | Remove more column-cache residue: The OP_SetColTab and OP_VerifyColTab opcodes and the associated SQLITE_DEBUG_COLUMNCACHE logic. (check-in: 80236e81ce user: drh tags: omit-column-cache) | |
| 15:53 | Further logic simplifications that flow out of the omission of the column cache. (check-in: 7d9072b027 user: drh tags: omit-column-cache) | |
| 15:28 | Add test cases for the constant expression fix of the previous check-in. (check-in: 95db5bd9fe user: drh tags: trunk) | |
| 15:16 | Ensure that all expressions that are to be evaluated once at the start of a prepared statement (the Parse.pConstExpr expressions) pass the sqlite3ExprIsConstantNotJoin() test. It is not sufficient to pass just the sqlite3ExprIsConstant() test as that would allow through column references that are bound to constants by the WHERE clause in the constant propagation optimization. This fixes a problem discovered by OSSFuzz. (check-in: 8bc7f84c39 user: drh tags: trunk) | |
| 14:30 | Remove additional traces of the column cache. (check-in: db6052e972 user: drh tags: omit-column-cache) | |
