|
2017-01-28
| ||
| 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: 4fe879d4b5 user: drh tags: trunk) | |

| 19:27 | Add the sha1.c loadable extension that implements the sha1() and sha1_query() SQL functions. (check-in: 24e77c1cef user: drh tags: trunk) | |
| 17:02 | Fix a problem causing the pre-update hook to be invoked by DROP TABLE statements. (check-in: fbb6bf1b69 user: dan tags: trunk) | |

| 16:24 | Merge all recent enhancements from trunk. (check-in: fe86ff5429 user: drh tags: est_count_pragma) | |
| 13:14 | Alternative ICU fix (compare to check-in [50e60cb4]) that avoids casting integers to pointers. (check-in: d9752c8f7c user: drh 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: 58f02e6eae user: drh tags: trunk) | |
| 01:25 | Another micro-optimization in accessPayload(). Slightly smaller and faster. (check-in: c012619b65 user: drh tags: trunk) | |
| 01:13 | Performance optimization in accessPayload(). (check-in: ebb1fd98d4 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: 68e7a8c676 user: drh tags: trunk) | |

| 21:30 | Remove an unreachable branch in the error handling logic for sqlite3BtreePayloadChecked(). (check-in: 293bf3ed7e 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: b4a98f6556 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: 9879be1899 user: drh tags: trunk) | |
| 01:54 | Enhancements to the kvtest utility program. Add the --jmode option. Improved output formatting. (check-in: 62a4851ccf 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: 50e60cb44f user: drh tags: trunk) | |
|
2017-01-25

| 14:58 | Experimental enhancement to automatically trim NULL values from the end of records, for a reduced disk footprint. This change also involves increasing the P5 operand from 8 to 16 bits. (check-in: 118ded403b user: drh tags: trim-nulls) | |
| 14:38 | Ensure that sqlite3_blob_reopen() correctly handles short rows. Fix for ticket [e6e962d6b0f06f46e]. (check-in: 8cd1a4451c user: drh tags: trunk) | |

| 21:12 | Experimental changes to permit a VFS to directly override the initial page size. (Leaf check-in: 6413172435 user: mistachkin tags: pagePerSector) | |
| 19:11 | Document the --mmap option in the --help screen for kvtest. Enhance kvtest so that numeric arguments can have suffixes like "K" or "M". Add kvtest to the unix makefiles. (check-in: 175bda8728 user: drh tags: trunk) | |
| 18:40 | Add the --mmap option to the kvtest utility program. (check-in: 4948f7e6d2 user: drh tags: trunk) | |
| 16:56 | Optimization: Try to avoid unnecessary btree searching when repositioning a cursor to the next row. (check-in: ee793d30c1 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: 7a4f512ddf 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: 03c601344e user: dan tags: trunk) | |

| 21:47 | A better implementation of the moveto-neighbor optimization that checks for nearby rows on adjacent pages. (Closed-Leaf check-in: 2c4ecb85a4 user: drh tags: btree-moveto-neighbor) | |
| 16:54 | B-tree optimization: When seeking on a rowid table that has already been positioned, check to see if the new row happens to be the next row on the same leaf page. That is a reasonably common case, and if it is true it avoids a full binary search. (check-in: 8e5cfb2039 user: drh tags: btree-moveto-neighbor) | |
| 16:27 | Change sqlite3_blob_reopen() to call sqlite3VdbeExec() directly rather than going through sqlite3_step(). Performance enhancement. (check-in: 347df3c1fd user: drh tags: trunk) | |
| 16:21 | Fix problems in the previous commit. (Leaf check-in: 74ad80eb74 user: dan tags: trigger-trace) | |
| 15:58 | Add extra (somewhat inefficient) trace callbacks for triggers if SQLITE_TRACE_TRIGGER is defined. (check-in: ffda1d1e1c user: dan tags: trigger-trace) | |
| 15:55 | In the kvtest.c test utility, reuse the buffer into which blobs are read, rather than reallocating it for each row. This is a closer match to how other test programs work, and thus provides a better comparison. (check-in: 0d1ad13a29 user: drh tags: trunk) | |
| 15:30 | A proof-of-concept for running sqlite3_blob_open() without using OP_Column when operating on a pure key/value table. This demo does not include any corrupt database checking. Uses about 3% fewer CPU cycles on a key/value performance test. (Leaf check-in: 4cda3b305b user: drh tags: kv-access-opt-demo) | |
| 14:11 | Remove an unnecessary sqlite3_bind_int64() call from sqlite3_blob_open(). Also other minor refactoring of the sqlite3_blob implementation. (check-in: 9d197a5323 user: drh tags: trunk) | |

| 16:46 | Add option "--stats" to test program kvtest. Specifying --stats causes kvtest to output information similar to the shell tool option of the same name. (check-in: 90291327fc user: dan tags: trunk) | |
| 16:09 | Get the "--testset rtree" option working on speedtest1. Add the --rtree, --lookaside, and --clang options to the speed-check.sh script. (check-in: 87b640c8d0 user: drh tags: trunk) | |
| 00:40 | Minor performance optimizations to sqlite3_blob_open() and sqlite3_blob_reopen(). (check-in: 52a61967d9 user: drh tags: trunk) | |
|
2017-01-19
| ||
| 21:20 | If compiled with SQLITE_INLINE_MEMCPY, all memcpy() calls are replaced with in-line code. With that change, cachegrind shows which memcpy() calls are taking the most time. This is a performance-measurement hack only and is not for production use. (check-in: 9ed3852161 user: drh tags: trunk) | |
| 18:20 | In the 'vtshim' extension, avoid accessing freed memory when handling errors from xCreate/xConnect. (check-in: ffd559afd3 user: mistachkin tags: trunk) | |
| 12:07 | Add a prototype of the sqlite3_kv_reset() interface. (Leaf check-in: 088c590379 user: drh tags: sqlite3_kv) | |

| 23:12 | For Windows 8.x and higher, require the SQLITE_WIN32_WIN8_SECTOR_SIZE compile-time option in order to enable sector size determination. (Leaf check-in: 47beb55c5b user: mistachkin tags: winSectorSize) | |
| 22:47 | In the 'windirent' test module, use a macro for the hidden/system attribute checking. (check-in: a84a08d071 user: mistachkin tags: trunk) | |
| 22:19 | Remove superfluous option to Tcl 'lsort' in the vtabH test file. (check-in: b92cc6e58a user: mistachkin tags: trunk) | |

| 20:14 | Add temporary code to record and report on the set of b-tree pages read and written by the current transaction. This is likely still buggy. (check-in: 2a8f6c890c user: dan tags: transaction-pages) | |
| 19:54 | Begin fleshing out the key/value accessor implementation. This is an incremental check-in. (check-in: 02d60e196f user: drh tags: sqlite3_kv) | |

|
2017-01-17
| ||
| 10:41 | Fix a problem that could cause a spurious SQLITE_NOMEM error when attempting to resume an RBU operation if the previous client failed right after completing the incremental checkpoint. Also a "cannot vacuum wal db" error that could occur when resuming an RBU vacuum if an error (OOM or IO error) occurs during the incremental checkpoint. (check-in: 681d96eb82 user: dan tags: trunk) | |
| 00:10 | Disable intrinsic functions for Windows using Clang, due to reports of linkage errors. This causes a 0.6% performance reduction. We will want to revisit this change in the future. (check-in: 7fd560c6d2 user: drh tags: trunk) | |

| 14:39 | When flattening a query of the form "SELECT * FROM (SELECT * FROM tbl WHERE x=?) WHERE y=?", ensure that the final WHERE clause is "x=? AND y=?" instead of "y=? AND x=?". Although it is still not guaranteed, this makes the order in which WHERE clause terms are processed comport more closely to users expectations. (check-in: cf7f9e6d5a user: dan tags: trunk) | |
