2017-01-23
| ||
| 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 | |
|
2017-01-22
| ||
| 16:34 | Fix an uninitialized variable in the command-line shell. check-in: 06b8001a user: drh tags: trunk | |
| 02:04 | Fixes to documentation comments in the public header file. check-in: 772dcb08 user: mistachkin tags: trunk | |
| 00:11 | Fix an initialized variable in kvtest. check-in: ed62c5a6 user: drh tags: trunk | |
|

| 21:47 | A better implementation of the moveto-neighbor optimization that checks for nearby rows on adjacent pages. Closed-Leaf check-in: 2c4ecb85 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: 8e5cfb20 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: 347df3c1 user: drh tags: trunk | |
| 16:21 | Fix problems in the previous commit. Leaf check-in: 74ad80eb user: dan tags: trigger-trace | |
| 15:58 | Add extra (somewhat inefficient) trace callbacks for triggers if SQLITE_TRACE_TRIGGER is defined. check-in: ffda1d1e 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: 0d1ad13a 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: 4cda3b30 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: 9d197a53 user: drh tags: trunk | |
|
2017-01-20
| ||
| 20:43 | Minor performance optimization and size reduction to the accessPayload() routine in btree.c. check-in: 264e5c10 user: drh tags: trunk | |
| 16:47 | Fix a typo in the help message for kvtest. check-in: 8971d98f 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: 90291327 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: 87b640c8 user: drh tags: trunk | |
| 00:40 | Minor performance optimizations to sqlite3_blob_open() and sqlite3_blob_reopen(). check-in: 52a61967 user: drh tags: trunk | |
|

| 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: 9ed38521 user: drh tags: trunk | |
| 18:20 | In the 'vtshim' extension, avoid accessing freed memory when handling errors from xCreate/xConnect. check-in: ffd559af user: mistachkin tags: trunk | |
| 12:07 | Add a prototype of the sqlite3_kv_reset() interface. Leaf check-in: 088c5903 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: 50ca94b9 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: 47beb55c user: mistachkin tags: winSectorSize | |
| 22:47 | In the 'windirent' test module, use a macro for the hidden/system attribute checking. check-in: a84a08d0 user: mistachkin tags: trunk | |
| 22:19 | Remove superfluous option to Tcl 'lsort' in the vtabH test file. check-in: b92cc6e5 user: mistachkin tags: trunk | |
| 22:16 | Make the vtabH-3.1 test more portable and robust. check-in: d3c91c1f 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: 26dd42b4 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: 2a8f6c89 user: dan tags: transaction-pages | |
| 19:54 | Begin fleshing out the key/value accessor implementation. This is an incremental check-in. check-in: 02d60e19 user: drh tags: sqlite3_kv | |
| 19:36 | Improve and update comments. check-in: 2dc16d34 user: mistachkin tags: winSectorSize | |
| 19:06 | Minimize the requested permissions when opening the volume on Windows 7 and Vista. check-in: 8d429a59 user: mistachkin tags: winSectorSize | |
| 17:20 | Baseline interface definition for the experimental sqlite3_kv accessor object. check-in: a435841e user: drh tags: sqlite3_kv | |
| 01:11 | Add runtime version checking for winSectorSize. check-in: cb9d1ab3 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: de699ead 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: 681d96eb 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: 7fd560c6 user: drh tags: trunk | |
|

| 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: 9b64af7b 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: 06136652 user: drh tags: automatic-index-affinity | |
| 16:01 | Add test cases for tickets [91e2e8ba6ff2e2] and [7ffd1ca1d2ad4ec]. check-in: 9d0dfe0b 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: e42ed9b4 user: drh tags: builtin-bswap64 | |

| 19:10 | Remove a branch that is probably unreachable, and which adds no value. check-in: 9acc7238 user: drh tags: trunk | |
| 16:21 | Fix harmless compiler warnings in the UPDATE code generator. check-in: 385db266 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: bddf3956 user: drh tags: trunk | |
| 15:19 | Test case macros to show that the previous check-in is well tested. Leaf check-in: bd8b977a user: drh tags: extra-testcase-macros | |

| 21:03 | Changes to allow some multi-row UPDATE statements to avoid the two-pass approach. check-in: 7ae6104a 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: 62257eb5 user: dan tags: onepass-update | |
| 19:03 | Fix a problem with single-pass multi-row UPDATE statements that invoke REPLACE conflict handling. check-in: 0a2b8e1b user: dan tags: onepass-update | |
| 16:52 | Attempt to detect physical sector sizes on Windows 8 and higher. check-in: 381fd34b 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: cab86c90 user: dan tags: onepass-update | |
| 14:21 | In the STAT4 computations, ensure that the aAvgEq values do not go negative. check-in: 4f83f680 user: drh tags: branch-3.8.9 | |

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: ff9eab95 user: drh tags: vdbe-aux-perf | |
| 19:55 | Remove a redundant assignment statement. check-in: a5fa0965 user: drh tags: trunk | |
| 19:27 | Performance optimization and size reduction in the OP_Variable opcode. check-in: 237aa974 user: drh tags: trunk | |
| 18:22 | Fix typo in a comment. No changes to code. check-in: d38fd229 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: 8a90f691 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: 6e106acd user: drh tags: trunk | |
| 13:43 | Add the SQLITE_UINT64_TYPE compile-time option. check-in: a5fe03bc 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: c8ca3e0a user: dan tags: begin-concurrent | |
| 06:33 | Upgrade this branch to 3.16 plus the various fixes that appeared after its release. check-in: d0e212d0 user: dan tags: begin-concurrent | |

| 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: 3178ec4c 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: db2c0960 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: f0495c51 user: drh tags: trunk | |
| 00:56 | Avoid duplicate b-tree searches in the duplicate row detector used to implement DISTINCT. check-in: d577dda0 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: 746b1836 user: drh tags: vdbe-aux-perf | |
