| 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) | |

| 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) | |

| 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) | |
|
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) | |
| 19:53 | 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) | |
|
2017-01-26
| ||
| 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) | |
|
2017-01-25
| ||
| 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) | |
|
2017-01-23
| ||
| 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) | |
|
2017-01-22
| ||
| 16:34 | Fix an uninitialized variable in the command-line shell. (check-in: 06b8001ade user: drh tags: trunk) | |
| 02:04 | Fixes to documentation comments in the public header file. (check-in: 772dcb08f4 user: mistachkin tags: trunk) | |
| 00:11 | Fix an initialized variable in kvtest. (check-in: ed62c5a656 user: drh tags: trunk) | |
|
2017-01-21
| ||
| 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) | |
|
2017-01-20
| ||
| 20:43 | Minor performance optimization and size reduction to the accessPayload() routine in btree.c. (check-in: 264e5c10d7 user: drh tags: trunk) | |
| 16:47 | Fix a typo in the help message for kvtest. (check-in: 8971d98f25 user: dan 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) | |
| 11:52 | Add test cases for the instrumentation on this branch. Fix some OOM handling issues in the same. (Leaf check-in: 50ca94b919 user: dan tags: transaction-pages) | |
|
2017-01-18
| ||
| 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) | |
| 22:16 | Make the vtabH-3.1 test more portable and robust. (check-in: d3c91c1fb3 user: mistachkin tags: trunk) | |
| 22:16 | Fix handling of initial hidden and/or system files in the opendir() implementation for Windows. No changes to non-test code. (check-in: 26dd42b462 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) | |
| 19:36 | Improve and update comments. (check-in: 2dc16d345b user: mistachkin tags: winSectorSize) | |
| 19:06 | Minimize the requested permissions when opening the volume on Windows 7 and Vista. (check-in: 8d429a59cd user: mistachkin tags: winSectorSize) | |
| 17:20 | Baseline interface definition for the experimental sqlite3_kv accessor object. (check-in: a435841e71 user: drh tags: sqlite3_kv) | |
| 01:11 | Add runtime version checking for winSectorSize. (check-in: cb9d1ab33d user: mistachkin tags: winSectorSize) | |
| 00:27 | When determining sector sizes on Windows 7 and Vista, make sure the target file is on the same volume as corresponding root directory. (check-in: de699ead5a user: mistachkin tags: winSectorSize) | |
|
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) | |
|
2017-01-16
| ||
| 18:10 | Back out check-in [0b3174e0b1364c] and replace it with a better fix for \ticket [91e2e8ba6ff2e2] - a fix that does not cause the problem identified by ticket [7ffd1ca1d2ad4ec]. Add new test cases for both tickets. (check-in: 9b64af7b52 user: drh tags: trunk) | |
| 16:43 | Back out check-in [0b3174e0b1364c] and replace it with a better fix for ticket [91e2e8ba6ff2e2] - a fix that does not cause the problem identified by ticket [7ffd1ca1d2ad4ec]. (Closed-Leaf check-in: 0613665274 user: drh tags: automatic-index-affinity) | |
| 16:01 | Add test cases for tickets [91e2e8ba6ff2e2] and [7ffd1ca1d2ad4ec]. (check-in: 9d0dfe0b08 user: drh tags: automatic-index-affinity) | |
| 11:54 | An example showing how to improve performance of sqlite3VdbeSerialPut() using the GCC intrinsic function __builtin_bswap64(). (Leaf check-in: e42ed9b4ad user: drh tags: builtin-bswap64) | |

| 12:53 | Fix the build for SQLITE_ENABLE_MEMORY_MANAGEMENT. (check-in: 8c85b8fdd7 user: drh tags: trunk) | |
|
2017-01-12
| ||
| 23:37 | Attempt to detect physical sector sizes on Windows Vista and higher. (check-in: 6e388423c4 user: mistachkin tags: winSectorSize) | |
| 19:10 | Remove a branch that is probably unreachable, and which adds no value. (check-in: 9acc72381c user: drh tags: trunk) | |
| 16:21 | Fix harmless compiler warnings in the UPDATE code generator. (check-in: 385db26667 user: drh tags: trunk) | |
| 16:14 | Remove an unnecessary corruption test from the btree balancer. If corruption is present, it will be found harmlessly by later tests. (check-in: bddf39562d user: drh tags: trunk) | |
| 15:19 | Test case macros to show that the previous check-in is well tested. (Leaf check-in: bd8b977abb user: drh tags: extra-testcase-macros) | |
| 15:11 | Improved detection of cells that extend into the reserved space at the end of the page while adjusting overflow page pointers during autovacuum. (check-in: 8097712c9c user: drh tags: trunk) | |
| 11:52 | Remove invalid test case from cursorhints2.test (check-in: 163cc1b2f7 user: drh tags: trunk) | |
| 11:50 | Make sure Tcl_AppendResult() always has a NULL-pointer argument at the end. (check-in: c07aef6f90 user: drh tags: trunk) | |

| 21:03 | Changes to allow some multi-row UPDATE statements to avoid the two-pass approach. (check-in: 7ae6104a3e user: dan tags: trunk) | |
| 20:10 | Fix a problem causing the pre-update hook to be passed an incorrect rowid value in some single-pass multi-row updates. (Closed-Leaf check-in: 62257eb53c user: dan tags: onepass-update) | |
| 19:03 | Fix a problem with single-pass multi-row UPDATE statements that invoke REPLACE conflict handling. (check-in: 0a2b8e1b9d user: dan tags: onepass-update) | |
| 16:52 | Attempt to detect physical sector sizes on Windows 8 and higher. (check-in: 381fd34b97 user: mistachkin tags: winSectorSize) | |
| 15:42 | Fix a problem preventing UPDATE statements that use a range-scan on the PK index of a WITHOUT ROWID table from using a one-pass strategy. (check-in: cab86c9094 user: dan tags: onepass-update) | |
| 14:21 | In the STAT4 computations, ensure that the aAvgEq values do not go negative. (check-in: 4f83f6806a user: drh tags: branch-3.8.9) | |
| 14:15 | In the STAT4 computations, ensure that the aAvgEq values do not go negative. (check-in: f58f75b5a0 user: drh tags: trunk) | |

| 15:08 | Fix a potential assertion fault discovered by OSS-Fuzz. (check-in: 71c03b59b6 user: drh tags: trunk) | |
|
2017-01-09
| ||
| 20:57 | Merge latest changes from trunk, and also move the perf-counter into the inner loop of sqlite3BtreeMovetoUnpacked(). (Leaf check-in: ff9eab9587 user: drh tags: vdbe-aux-perf) | |
| 19:55 | Remove a redundant assignment statement. (check-in: a5fa09657b user: drh tags: trunk) | |

| 18:22 | Fix typo in a comment. No changes to code. (check-in: d38fd22935 user: mistachkin tags: trunk) | |
| 18:20 | Try to move OP_Concat operations outside the inner loop. This turns out to make things very slightly slower, at least in speedtest1.c. (Closed-Leaf check-in: 8a90f69139 user: drh tags: failed-optimization) | |
| 15:44 | Modify the OP_RowData opcode so that when P3!=0 it is allowed to hold an ephemeral copy of the content. This avoids unnecessary memcpy() operations in the xfer-optimization and VACUUM. (check-in: 6e106acd74 user: drh tags: trunk) | |
| 13:43 | Add the SQLITE_UINT64_TYPE compile-time option. (check-in: a5fe03bc41 user: drh tags: trunk) | |

| 06:53 | Disable the optimization from [8cb8516d] (omit TableLock instructions for non-sharable databases) on this branch. This branch uses the TableLock instructions to ensure that the db schema is not written from within a BEGIN CONCURRENT transaction. (check-in: c8ca3e0a8d user: dan tags: begin-concurrent) | |
| 06:33 | Upgrade this branch to 3.16 plus the various fixes that appeared after its release. (check-in: d0e212d08f user: dan tags: begin-concurrent) | |
|
2017-01-07
| ||
| 14:47 | Improvements to the iIdxNoSeek optimization of sqlite3GenerateRowDelete() so that it is automatically disabled for BEFORE triggers but works in all other cases. (check-in: 3178ec4c27 user: drh tags: trunk) | |
| 14:26 | Critical fix to the previous check-in so that it works when there are BEFORE triggers that move the cursor before the OP_Delete has a chance to be applied. (check-in: db2c0960ff user: drh tags: trunk) | |
| 03:26 | Avoid an unnecessary btree seek while deleting an index entry due to a conflict on a REPLACE operation. (check-in: f0495c5133 user: drh tags: trunk) | |
| 00:56 | Avoid duplicate b-tree searches in the duplicate row detector used to implement DISTINCT. (check-in: d577dda0a7 user: drh tags: trunk) | |
| 00:42 | This hack illustrates how to use the VDBE_PROFILE mechanism to show which bytecode operators are using resources other than time. In this case, the number of loops through the binary search code in sqlite3BtreeMovetoUnpacked() is measured, for the purpose of helping to identify unnecessary btree searches. (check-in: 746b183683 user: drh tags: vdbe-aux-perf) | |
