| 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

| 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) | |
|

| 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) | |

| 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) | |

| 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.

| 23:18 | Put an ALWAYS() on an unreachable branch in the sqlite3ExprListDup() routine. (check-in: 2caaaab5e0 user: drh tags: rowvalue-update-trigger) | |
| 22:36 | Proposed fix for the row-value TRIGGER UPDATE problem described in ticket [8c9458e7]. (check-in: 61a442ea2c user: drh tags: rowvalue-update-trigger) | |
| 19:10 | Increase the version number to 3.17.0 for the next release cycle. (check-in: 16415b5aad user: drh tags: trunk) | |
| 19:02 | Provide the SQLITE_DEFAULT_LOOKASIDE compile-time option and make it's default value be 1200,100 (raised from 512,125 in the latest release). (check-in: 584da48f9e user: drh tags: trunk) | |
| 18:40 | Change SQLITE_DEFAULT_PCACHE_INITSZ from 100 to 20, which is experimentally determined to be slightly faster. (check-in: 12d9493cb2 user: drh tags: trunk) | |
| 18:19 | Avoid unnecessary calls to sqlite3BtreeEnterAll() and sqlite3BtreeLeaveAll() when no btree is using shared-cache. (check-in: cfb3158204 user: drh tags: trunk) | |
| 12:20 | Add the --all option to the wordcount test program. Fix the speedtest1 test program so that it builds on MSVC and so that the --lookaside 0 0 option works. (check-in: cb338f367e user: drh tags: trunk) | |
| 11:57 | Version 3.16.0 (check-in: 04ac0b75b1 user: drh tags: trunk, release, version-3.16.0) | |

| 12:44 | Detect row-value comparison size mismatches even when the size of one operand is obscured by an unexpanded subquery. (check-in: 2c4d167ccd user: drh tags: trunk) | |
|
2016-12-31

| 21:55 | Add the --help and --all options to the wordcount test utility. (Closed-Leaf check-in: 18baeadfc8 user: drh tags: wordcount-enhancement) | |
| 18:37 | In speedtest1.c, make the "--lookaside 0 0" option completely disable lookaside. (Closed-Leaf check-in: 52b99bcbf1 user: drh tags: speedtest1) | |
| 14:33 | Minor #include change to speedtest1.c so that it will compile under MSVC. (check-in: 8c28fde004 user: drh tags: speedtest1) | |

| 17:40 | Fix a crash that could occur following an OOM in the group_concat() function if the second argument is an SQLITE_BLOB value. (check-in: 14d855d2b2 user: dan tags: trunk) | |
| 15:16 | Strengthen the defense against OOM in the instr() SQL function. (check-in: a0971e7136 user: drh tags: trunk) | |
| 14:25 | Add a test to ensure that the app-defined pcache xFetch() method is never passed a key of zero. (check-in: 0bdbe49c6d user: drh tags: trunk) | |
| 14:15 | Avoid passing NULL pointers to memcmp() or memcpy(), even when the "number-of-bytes" argument is passed 0. (check-in: 56ff72ab44 user: dan tags: trunk) | |
| 13:55 | Clarify the expectations for the behavior of the xFetch method on the sqlite3_pcache_methods object for the case when the key is zero. (Closed-Leaf check-in: b0810ac1b2 user: drh tags: pcache1-zero-page) | |
| 13:40 | Improved detection of zero page numbers in the page cache. (check-in: 5550e815dd user: drh tags: pcache1-zero-page) | |

| 19:48 | Fix harmless compiler warnings in the command-line shell and in Lemon. (check-in: afcdc4a60e user: drh tags: trunk) | |
| 17:25 | In kvtest.c, use stat() instead of fseek()/ftell() to determine the size of a BLOB to be read directly from disk. This makes the pile-of-files database more competative against SQLite. (check-in: a7dca29f03 user: drh tags: trunk) | |
| 16:58 | Add the kvtest.c test program used to show that it is many times faster to read thumbnail and similar BLOBs out of an SQLite database than it is to read them as separate files from the filesystem. (check-in: 8074d59cf1 user: drh tags: trunk) | |
| 16:49 | Add more detail to the header command to further explain how to compile and use the kvtest.c utility. (Closed-Leaf check-in: 55d29839c9 user: drh tags: kvtest) | |

| 15:59 | Do not allow the nockpt.test module to run under the inmemory_journal permutation. (check-in: a6af06f164 user: drh tags: trunk) | |
| 13:33 | Allow sqlite3_interrupt() to be invoked on a database connection that is in the process of being closed even if SQLITE_ENABLE_API_ARMOR is defined. (check-in: 7854bee260 user: drh tags: trunk) | |
| 12:45 | Adjust a corruption test case to accommodate the sqlite3BtreeInsert() optimization of check-in [0b86fbca66]. (check-in: 4cb0945f13 user: drh tags: trunk) | |
| 12:35 | Disable new test modules nockpt.test and interrupt2.test for incompatible permutations. Add a CORRUPT_DB term to an assert() in vdbe.c. (check-in: a54e619e6f user: drh tags: trunk) | |
| 12:08 | Avoid a potential (harmless) signed integer overflow in memory usage accounting when calling sqlite3_realloc() to reduce the size of an allocation. (check-in: 2d71cbdf6b user: drh tags: trunk) | |
| 02:43 | Minor changes to make some newer test cases work under more compile-time options. (check-in: 382eea36c5 user: drh tags: trunk) | |

| 12:25 | During fuzz testing with the fuzzcheck utility program, impose a record length limit of 100MB and a limit on the length of LIKE strings of 50 bytes. (check-in: edc9db41f3 user: drh tags: trunk) | |
| 12:14 | Enable ossfuzz.c to build even if SQLITE_OMIT_PROGRESS_CALLBACK is defined. (check-in: a37c00dcd1 user: drh tags: trunk) | |
| 01:41 | Remove an incorrect ALWAYS() macro from balance_nonroot(), which could result in corrupt databases if it were optimized out. This ALWAYS was added only two weeks ago (check-in [f9f2e23bbd68a]) and has never appeared in an official release. (check-in: e447b23cfd user: drh tags: trunk) | |
| 00:18 | Add the built-in affinity() SQL function. (check-in: 57e40e1cb1 user: drh tags: affinity-sql-func) | |
| 00:15 | Enhance the fuzztest utility with the --prng-seed option. Always reseed the PRNG prior to each test. (check-in: 8c5187f69d user: drh tags: trunk) | |

| 21:32 | Combine the implementations of the ".tables" and ".indexes" commands in the command-line shell. The ".indexes" command now puts the indexes in multiple columns, just like ".tables" and shows all indexes in all attached databases. (check-in: def2933365 user: drh tags: trunk) | |
| 19:37 | The schema name "main" is always an acceptable alias for the primary database even if the primary database is renamed using SQLITE_DBCONFIG_MAINDBNAME. (check-in: 2f481b854f user: drh tags: trunk) | |
| 18:18 | Change the output format of the ".databases" command in the command-line shell so that it shows the schema name, a colon, and the corresponding filename. (check-in: 8558512e9c user: drh tags: trunk) | |
| 18:04 | In the command-line shell, improve the formatting to the ".databases" command and on the ".tables" command, only show the schema prefix for databases past the first ("main") database. (check-in: c0d5626e27 user: drh tags: trunk) | |

| 16:05 | Fill in missing opcode documentation entries for OP_SorterNext and OP_SorterSort. (check-in: 2940661b8c user: drh tags: trunk) | |
| 13:54 | Use the VList object to capture the mapping between SQL parameter names and variable numbers in a single memory allocation. (check-in: 99fddf2ecb user: drh tags: trunk) | |
| 13:52 | Add check to prevent a VList from growing after pointers to labels have been taken. (Closed-Leaf check-in: aa23d7eaf6 user: drh tags: VList) | |
| 13:30 | Fix the VList object so that it actually works. (check-in: 9dcd85698a user: drh tags: VList) | |
| 03:59 | Use the VList object to replace Parse.azVar for tracking the mapping between SQL parameter names and parameter numbers. There is a performance improvement, though there are still a few hiccups in the current code. (check-in: 68ecafa142 user: drh tags: VList) | |

| 21:26 | Change the default lookaside configuration from 500 slots of 128 bytes each to 125 slots of 512 bytes each. This uses the same amount of memory (64,000 bytes) but seems to perform much better in test applications. (check-in: 52a12e47de user: drh tags: trunk) | |
| 19:45 | Simplifications to the way UnpackedRecord objects are allocated. Smaller and faster code that also fixes a subtle (currently unreachable) bug. (check-in: f7ab01f254 user: drh tags: trunk) | |
|
2016-12-18
| ||
| 17:42 | Change the OP_IfNotZero opcode so that it decrements register P1 by 1 rather than the value in P3, and so that it only decrements if originally positive. This avoids decrementing the smallest 64-bit signed integer. (check-in: 165c044686 user: drh tags: trunk) | |

| 21:07 | Refinements to the new dbfuzz test program. (check-in: 50325abe79 user: drh tags: trunk) | |
| 20:27 | Enhance fuzzershell.c to read and execute SQL commands in the autoexec table of the database under test. Add the dbfuzz.c test program combining selected features of fuzzershell.c and fuzzcheck.c. (check-in: ef6e071a62 user: drh tags: trunk) | |
| 08:18 | Fix a problem in the shell tools readfile() command causing blobs to be truncated at the first embedded 0x00 byte in release builds, or an assert() to fail in a debug build. (check-in: 8dedd6ad44 user: dan tags: trunk) | |

| 18:43 | Add the ".lint fkey-indexes" command to the command-line shell. (check-in: 94689e3bda user: drh tags: trunk) | |
| 18:41 | Fix minor issues with the ".lint" command implemention in the shell and the shell help text related to ".lint". (Closed-Leaf check-in: 1268dc7771 user: drh tags: fkey-missing-indexes) | |
| 18:14 | Built-in PRAGMA statements without side-effects can be invoked as table-valued functions by prefixing their name with "pragma_". (check-in: d66ec5cfb6 user: drh tags: trunk) | |
