| 23:42 | Fix an issue with the "+" attribute in printf(). (check-in: bdfd1eb1d7 user: drh tags: fp-to-decimal-refactor) | |
| 23:18 | Begin cutting over sqlite3FpDecode() into printf(). The code in this check-in gets a lot right, but there are still some formatting discrepencies. (check-in: c134d423e7 user: drh tags: fp-to-decimal-refactor) | |
| 19:41 | Add decimal rounding to the sqlite3FpDecode() routine. (check-in: 27871140ca user: drh tags: fp-to-decimal-refactor) | |

| 18:35 | Experiments with a new algorithm for converting ieee-754 binary64 numbers into decimal. (check-in: e923405e44 user: drh tags: fp-to-decimal-refactor) | |
| 18:31 | Add support for sqlite3_stmt_scanstatus_v2() profiling of GROUP BY clauses that use a temp b-tree, and for sub-queries implemented as co-routines. (check-in: 7afad1f759 user: dan tags: trunk) | |
| 18:23 | Improve support for sqlite3_stmt_scanstatus_v2() profiling of sub-queries implemented as co-routines. (Closed-Leaf check-in: 4e8718dc35 user: dan tags: scanstatus-exp) | |
| 17:14 | Add support for sqlite3_stmt_scanstatus_v2() profiling of GROUP BY clauses that use a temp b-tree. (check-in: 796eadcc50 user: dan tags: scanstatus-exp) | |
| 16:16 | Add extra debugging code for sqlite3_stmt_scanstatus_v2() to test1.c. (check-in: f936f10140 user: dan tags: trunk) | |
| 14:01 | Completely unwind the enhanced precision sum() from [a915f15a916af698] so as not to offend UBSAN and OSS-Fuzz. (check-in: 85be05b66e user: drh tags: trunk) | |
| 12:59 | Omit the doubleToReal() function in vdbemem.c. Use the equivalent sqlite3RealToI64() function in its place. (check-in: 625820e8eb user: drh tags: trunk) | |
| 11:51 | Make the sum() function less precise and slower in order to avoid harmless signed integer overflow UBSAN warnings from OSS-Fuzz. (check-in: 1be0646a2c user: drh tags: trunk) | |

| 22:46 | Small performance improvement to sqlite3_finalize(). (check-in: 8a6913b66c user: drh tags: trunk) | |
| 14:19 | Fix documentation and test-script typos and a dependency problem on a Makefile. Fix the sqlite_stmt extension virtual table so that it shows the state of all prepared statements for a single instant in time. (check-in: 0a9e08be6d user: drh tags: branch-3.39) | |
| 11:01 | Add missing "finish_test" command to the end of test script merge1.test. (check-in: 13cb3f1e63 user: dan tags: trunk) | |

| 14:04 | Fix a memory leak in fts5 that could occur when processing a query containing multiple classes of error. (check-in: 7c279670f5 user: dan tags: trunk) | |
| 12:11 | Fix an assert() in fts5 that might fail when dealing with corrupt records. (check-in: 9e760e2560 user: dan tags: trunk) | |
| 11:53 | Do not enforce the SQLITE_LIMIT_FUNCTION_ARG limit for internally generated SQL. This prevents problems with statements like ALTER TABLE if the function argument limit is set too low. Forum post 17735aa21f3ddab2. (check-in: 763fdec5b3 user: drh tags: trunk) | |

| 18:21 | Add a test to ensure that "PRAGMA wal_checkpoint = FULL" invokes the busy-handler to wait on read-locks. (check-in: f068fb1162 user: dan tags: trunk) | |
| 15:32 | Avoid a potential buffer overread in fts3 when processing corrupt records. (check-in: 4d0cfb1236 user: dan tags: trunk) | |

| 17:28 | Make use of the _byteswap_ushort() and _byteswap_ulong() compiler intrinsics for MSVC, when available. (check-in: fe144dd73f user: mistachkin tags: trunk) | |
| 16:29 | Merge all the latest enhancements from trunk. This merge include FTS5 and a number of notable performance enhancements. (check-in: 39936b33b0 user: drh tags: sessions) | |
| 15:10 | Make use of built-in bswap32() and bswap16() functions in GCC/Clang for a significant performance improvement there. (check-in: 8bfcda3d10 user: drh tags: trunk) | |
| 14:01 | Only use __builtin_bswap16() with GCC 4.8 and later. (Closed-Leaf check-in: ce8177e3e6 user: drh tags: bswap-functions) | |
| 13:36 | • Edit [bc27ebd7f73e9fc8|bc27ebd7f7]: Move to branch bswap-functions. (artifact: 1a4a7643b7 user: drh) | |
| 13:28 | Remove the use of htonl() in the previous check-in due to linkage issues. Add the get2byteAligned() macro and use it for access to the cell offsets on btree pages for about a 1% performance gain. (check-in: 79ff36b717 user: drh tags: bswap-functions) | |
| 12:47 | Make use of htonl() and __builtin_bswap32() for faster implementations of sqlite3Get4byte() and sqlite3Put4byte(). (check-in: bc27ebd7f7 user: drh tags: bswap-functions) | |
| 11:07 | Change an unreachable branch into an assert() in sqlite3PagerAcquire() and optimize sqlite3PcacheOpenSavepoint() by factoring out rarely used code into a subroutine. (check-in: b406b20ecd user: drh tags: trunk) | |
| 03:57 | Optimization to the sqlite3PcacheFetch() logic. (check-in: d9a0481ce0 user: drh tags: trunk) | |
| 03:34 | Put all variable declarations for sqlite3PagerWrite() at the beginning of the block. Syntax only - no logic changes. (check-in: a0fa6b3ba5 user: drh tags: trunk) | |
| 03:18 | Implement sqlite3Strlen30() using strlen() from the C library. (check-in: 8001aa52bd user: drh tags: trunk) | |
| 03:13 | Change sqlite3ApiExit() so that its first argument is never NULL. (check-in: 791b706ec6 user: drh tags: trunk) | |
| 02:47 | Put BtCursor objects on a singly-linked list instead of a doubly-linked list. Add the BTCF_Multiple flag. Only invoke saveAllCursors() when using a cursor that has BTCF_Multiple set. (check-in: 429ccef2b3 user: drh tags: trunk) | |
| 01:25 | Convert several 5-year-old and older NEVER() macros into assert(). (check-in: ed54c14ea8 user: drh tags: trunk) | |

| 04:36 | Do not call pager_open_journal() from within PagerBegin() if the connection is in exclusive-access mode. It will be called from within PagerWrite() just as it is for non-exclusive mode anyway. (check-in: cdf2c5c2dd user: dan tags: trunk) | |
| 04:29 | Add coverage test cases. Have sqlite3_backup_step() transform SQLITE_IOERR_NOMEM to SQLITE_NOMEM before returning. (check-in: 5e19bc360e user: dan tags: trunk) | |
