|
2017-02-02
| ||
| 23:57 | Add the sqlite3_blob_reset() interface. Enhance the behavior of sqlite3_blob objects so that they can go active again after encountering an error by rerunning sqlite3_blob_reopen(). More work needed on the documentation. check-in: 53b77838 user: drh tags: sqlite3_blob_reset | |

| 16:08 | Fix a potential uninitialized (though harmless) variable in RTREE. check-in: a1c74e09 user: drh tags: rtree-sqlite3_blob | |
| 15:35 | The sqlite3_blob_close() interface can cause recursive invocations of nodeBlobReset() in RTREE. Make sure that does not cause problems. check-in: 88333441 user: drh tags: rtree-sqlite3_blob | |

| 23:03 | Backout the change in [02f6293f27] as it causes MSVC to complain. check-in: aaae74d0 user: mistachkin tags: trunk | |
| 22:59 | Fix C99-style variable declaration issue seen with older versions of MSVC. check-in: 54d28546 user: mistachkin tags: trunk | |
| 22:43 | Fix harmless compiler warnings seen with MSVC. Closed-Leaf check-in: 997f765b user: mistachkin tags: msvcWarn | |

| 20:46 | In the amalgamation, allocate the parser engine object from stack rather than from heap, for improved performance. This only happens in the amalgamation, since otherwise the sqlite3RunParser() routine does not know the object size. check-in: 4fe879d4 user: drh tags: trunk | |
| 19:53 | Fix a couple comment typos. No changes to code. check-in: 2a2e7d86 user: mistachkin tags: trunk | |
| 19:45 | Avoid redundant table b-tree cursor seeks in UPDATE statements that use the two-pass strategy. check-in: dc555b10 user: dan tags: trunk | |
| 15:26 | Updates to the sqlite3_blob documentation. No changes to code. check-in: 426b440a user: drh tags: trunk | |

| 19:27 | Add the sha1.c loadable extension that implements the sha1() and sha1_query() SQL functions. check-in: 24e77c1c user: drh tags: trunk | |
| 17:02 | Fix a problem causing the pre-update hook to be invoked by DROP TABLE statements. check-in: fbb6bf1b user: dan tags: trunk | |

| 01:52 | In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl". check-in: 58f02e6e user: drh tags: trunk | |
| 01:25 | Another micro-optimization in accessPayload(). Slightly smaller and faster. check-in: c012619b user: drh tags: trunk | |
| 01:13 | Performance optimization in accessPayload(). check-in: ebb1fd98 user: drh tags: trunk | |
| 00:31 | Simplify the accessPayload() routine so that it always populates the overflow page cache. In the one case where populating the page cache can lead to problems, simply invalidate the cache as soon as accessPayload() returns. This simplification reduces code size and helps accessPayload() to run a little faster. This backs out the eOp==2 mode of accessPayload() added by check-in [da59198505]. check-in: 68e7a8c6 user: drh tags: trunk | |

| 21:30 | Remove an unreachable branch in the error handling logic for sqlite3BtreePayloadChecked(). check-in: 293bf3ed user: drh tags: trunk | |
| 18:00 | Improvement to the OP_Permutation opcode to prevent it from using CPU cycles for initialization in prepared statements that do not use that opcode. check-in: b4a98f65 user: drh tags: trunk | |
| 17:26 | Remove the obsolete lastRowid cache from the sqlite3VdbeExec() for a size reduction and performance improvement. check-in: b4803184 user: drh tags: trunk | |

| 02:26 | Make SQLITE_DIRECT_OVERFLOW_READ work for in WAL mode as long as the page being read is not in the the -wal file. check-in: 9879be18 user: drh tags: trunk | |
| 01:54 | Enhancements to the kvtest utility program. Add the --jmode option. Improved output formatting. check-in: 62a4851c user: drh tags: trunk | |
| 00:58 | Modify the ICU extension to use a static initializer, as VC++ complains about a dynamic initialization. Maybe the dynamic structure initialization is a GCC extension. This fixes a problem identified on the SQLite mailing list by Ziemowit Laski. check-in: 50e60cb4 user: drh tags: trunk | |

| 14:38 | Ensure that sqlite3_blob_reopen() correctly handles short rows. Fix for ticket [e6e962d6b0f06f46e]. check-in: 8cd1a445 user: drh tags: trunk | |
| 13:54 | Fix SQLITEINT_H macro usage in two extensions. check-in: 0803390c user: drh tags: trunk | |

| 15:58 | Add the missing SQLITE_API symbol to test_delete.c (it is not added automatically as this file is not part of the amalgamation). check-in: 7a4f512d user: dan tags: trunk | |
| 07:06 | Fix a problem preventing FTS5 from correctly passing the FTS5_TOKENIZE_PREFIX flag to custom tokenizer implementations. check-in: 03c60134 user: dan tags: trunk | |
