| 19:10 | Very small performance improvements and size reductions in sqlite3VdbeExec() and blobSeekToRow(). (check-in: 85dddf2b45 user: drh tags: trunk) | |
| 19:02 | Simplifications to blobSeekToRow(). (Closed-Leaf check-in: 495ea82409 user: drh tags: micro-optimizations) | |
| 17:31 | Add a speed-test program for the sessions module. (Closed-Leaf check-in: 25f1275fe3 user: dan tags: preupdate-without-rowid) | |
| 16:49 | Remove a C99-style comment. Fixes to the kvtest-speed.sh script. (check-in: 91eb6b628e user: drh tags: micro-optimizations) | |
| 16:43 | Remove another unnecessary local variable initialization from sqlite3VdbeExec() (check-in: 2361b03b61 user: drh tags: micro-optimizations) | |
| 16:34 | Remove an unnecessary initialization of the pOp variable in sqlite3VdbeExec(). (check-in: 02f6293f27 user: drh tags: micro-optimizations) | |
| 15:29 | Add the "stat" command to kvtest.c. Also add the --variance option to the "init" command. Add the tool/kvtest-speed.sh script used for doing performance testing on key/value access patterns. (check-in: b63deed600 user: drh tags: trunk) | |
| 15:27 | Fix a typo in a comment. (check-in: bd22bf9cbe user: drh tags: trunk) | |
| 14:08 | Merge latest trunk with this branch. (check-in: 4a592abbc5 user: dan tags: preupdate-without-rowid) | |
| 12:41 | Further minor enhancement and size reduction in sqlite3ExprAssignVarNumber(). (check-in: eacfdcf257 user: drh tags: trunk) | |
| 03:52 | Performance optimization in sqlite3ExprAssignVarNumber(). (check-in: 5987ca1ff9 user: drh tags: trunk) | |
|
2017-01-30
| ||
| 19:44 | Experimental change to invoke the preupdate hook when WITHOUT ROWID tables are written. (check-in: 856f8604c5 user: dan tags: preupdate-without-rowid) | |
| 11:38 | Fix building with SQLITE_OMIT_FOREIGN_KEY defined. (check-in: e93d2c49a4 user: dan tags: trunk) | |
|

| 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) | |
| 19:53 | Fix a couple comment typos. No changes to code. (check-in: 2a2e7d86b2 user: mistachkin tags: trunk) | |
| 19:45 | Avoid redundant table b-tree cursor seeks in UPDATE statements that use the two-pass strategy. (check-in: dc555b1039 user: dan tags: trunk) | |
| 15:26 | Updates to the sqlite3_blob documentation. No changes to code. (check-in: 426b440a57 user: drh tags: trunk) | |
| 13:40 | In the speed-check.sh script, automatically invoke "fossil test-diff --tk" on the cachegrind output against trunk, if not generating a trunk run. (check-in: aa1ab37100 user: drh tags: trunk) | |
| 06:50 | Fix a typo in the docs for sqlite3_update_hook(). (check-in: 7c029655cc user: dan tags: trunk) | |
|
2017-01-27
| ||
| 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) | |
| 16:39 | Merge all recent trunk enhancements into the apple-osx branch. (check-in: 0e14fe1b98 user: drh tags: apple-osx) | |
| 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) | |
| 17:26 | Remove the obsolete lastRowid cache from the sqlite3VdbeExec() for a size reduction and performance improvement. (check-in: b480318465 user: drh tags: trunk) | |
| 17:11 | Performance optimization in sqlite3VdbeCloseStatement(). (check-in: 1e96e5ec1e user: drh tags: trunk) | |
| 16:54 | Performance optimization to sqlite3_blob_read(). (check-in: 7459f4b7ed user: drh tags: trunk) | |
| 16:27 | Minor simplification and performance optimization for Direct Overflow Read. (check-in: 3e96d6efa8 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) | |

| 20:55 | Trim NULL values off the end of records when the SQLITE_ENABLE_NULL_TRIM compile-time option is used. Increase the size of the P5 operand to 16 bits. Fix a problem with short records in the sessions extension. (check-in: 4801bd59a0 user: drh tags: trunk) | |
| 18:53 | Fix another pre-update hook issue, this time in sqlite3preupdate_old(). (Closed-Leaf check-in: c7651d21bf user: dan tags: trim-nulls) | |

| 17:44 | Fix a problem with the pre-update hook on this branch. (check-in: 6fc4fbfa29 user: dan tags: trim-nulls) | |
| 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) | |
| 13:54 | Fix SQLITEINT_H macro usage in two extensions. (check-in: 0803390c15 user: drh tags: trunk) | |
| 04:41 | Ensure that sqlite3_blob_reopen() correctly handles short rows. Proposed fix for ticket [e6e962d6b0f06f46e]. Further testing needed. (Closed-Leaf check-in: 57d8dad35c user: drh tags: blob_reopen-fix) | |

| ||
| 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) | |
