| 18:55 | If the user has not set it explicitly, set the "PRAGMA synchronous" setting to SQLITE_DEFAULT_SYNCHRONOUS when a database connection changes from wal to rollback journal mode. (check-in: 5c604479fd user: dan tags: trunk) | |
| 18:54 | Fix a typo causing the build to fail if SQLITE_DEFAULT_SYNCHRONOUS==SQLITE_DEFAULT_WAL_SYNCHRONOUS. (Closed-Leaf check-in: df39adeaa4 user: dan tags: default-synchronous-fix) | |
| 18:53 | • Edit [78030c0f52aa39fb|78030c0f52]: Move to branch default-synchronous-fix. (artifact: b32da8e13d user: dan) | |
| 18:14 | If the user has not set it explicitly, set the "PRAGMA synchronous" setting to SQLITE_DEFAULT_SYNCHRONOUS when a database connection changes from wal to rollback journal mode. (check-in: 78030c0f52 user: dan tags: default-synchronous-fix) | |
| 14:28 | Simplified OOM detection in the instr() SQL function. (check-in: 6d85eb5736 user: drh tags: trunk) | |
| 13:30 | Fix an uninitialized variable reference in the text generator for "PRAGMA vdbe_trace=ON" output. Problem discovered by OSS-Fuzz. (check-in: e3d487162d user: drh tags: trunk) | |
| 13:25 | • Edit [6e59e903e4e95661|6e59e903e4]: Edit check-in comment. (artifact: 8f0f466805 user: drh) | |
| 13:14 | Fix a problem in the "showdb" utility that prevents it from correctly decoding cells with no content beyond the record header. (check-in: eb7680a1c0 user: drh tags: trunk) | |
| 12:11 | Fix a crash that could follow an OOM condition in the instr() SQL function. Problem discovered by OSS-Fuzz. (check-in: 6e59e903e4 user: dan tags: trunk) | |

| 21:29 | The prepared statements for some pragmas can now be reused without invoking an automatic reprepare. (check-in: 97b0e88cc7 user: drh tags: trunk) | |
| 20:53 | Merge the changes on the reusable-pragma branch into this one. (check-in: 6c4a17b963 user: dan tags: fts5-data-version) | |
| 20:44 | Some pragmas can be reused without an automatic reprepare. (Closed-Leaf check-in: db1ce7e13e user: drh tags: reusable-pragma) | |
| 20:05 | Fix a comment on the freelist_count and data_version pragmas. (check-in: 10a3e2a01d user: drh tags: trunk) | |
| 19:53 | Add a cast to an implict (size_t -> int) conversion in fts5_expr.c. (check-in: d9b5ff7aba user: dan tags: trunk) | |
| 19:48 | Have fts5 cache the decoded structure of fts5 indexes in memory. Use "PRAGMA data_version" to detect stale caches. (check-in: 33ef2210ef user: dan tags: fts5-data-version) | |
| 19:45 | Enhance Lemon so that it reorders the reduce rules such that rules without actions occur at the end and so that the first rule is number 0. This reduces the size of the jump table on the reduce switch, and helps the parser to run faster. (check-in: d5712f21ec user: drh tags: trunk) | |
| 19:34 | Merge the latest enhancements from trunk. (check-in: a7978ab6d2 user: drh tags: begin-concurrent) | |
| 19:10 | Avoid a few unnecessary fstat()s on journal files. (check-in: dbf8470591 user: drh tags: trunk) | |
| 18:26 | Fix the query planner so that it is able to use the integer primary key from an index as part of a multi-column constraint. (check-in: 96ea990942 user: drh tags: trunk) | |
| 01:16 | Merge all recent enhancements from trunk. (check-in: 6a7ee04b0d user: drh tags: sessions) | |
| 01:09 | Merge the SQLITE_OMIT_CODEC_FROM_TCL compile-time option from trunk. (check-in: 161d91e485 user: drh tags: apple-osx) | |
| 01:03 | Add the SQLITE_OMIT_CODEC_FROM_TCL compile-time option. (check-in: 45f7f0c80b user: drh tags: trunk) | |
| 00:36 | Rearrange some internal fields in the sqlite3_stmt object to avoid a harmless TSAN warning. (check-in: e0b116edd6 user: drh tags: trunk) | |

| 20:40 | Make SQLite slightly more likely to use an auto-index within a sub-query. (check-in: ab832336f4 user: dan tags: trunk) | |
| 18:08 | Fix typo of test prefix in the new WHERE test file. (check-in: 34779c528f user: mistachkin tags: trunk) | |
| 17:48 | When the WHERE clause contains two OR-connected terms with identical operands but different operators, try to combine them into a single term. Example: (X=A OR X>A) becomes (X>=A). (check-in: 8bdda827a3 user: drh tags: trunk) | |
| 17:30 | • Edit [f2207a0691ed3610|f2207a0691]: Mark "Closed". (artifact: 6e50a68eac user: drh) | |
| 17:07 | Modify the fts3query.test script so that it works even when testfixture is built using a version of TCL that is unable to sort the integer -9223372036854775808 (check-in: f61fd24b4d user: drh tags: trunk) | |
| 16:44 | When deleting the master journal to commit a multi-database transaction, do not sync the directory if PRAGMA synchronous=OFF for all participating database files. (check-in: 018d767140 user: drh tags: trunk) | |
| 16:28 | When estimating the number of rows visited by a range scan for which the keys consist of more than one field, consider prefixes of stat4 samples as well as the full samples. This generates more accurate estimates. (check-in: 3e0590dee0 user: dan tags: trunk) | |
| 13:48 | Use #ifdef to omit code that is only used for STAT3 and STAT4. (check-in: f2c9c5b57b user: drh tags: trunk) | |
| 13:12 | Improved comments. No code changes. (Closed-Leaf check-in: 23f71a2638 user: drh tags: combine-disjuncts) | |
| 12:13 | When a WHERE clause contains disjuncts with the same operands, try to combine them into a single operator. Example: (x=A OR x>A) becomes (x>=A). (check-in: 7a3097689d user: drh tags: combine-disjuncts) | |
| 09:21 | Another test case for the planner change on this branch. (Closed-Leaf check-in: f2207a0691 user: dan tags: stat4-change) | |

| 20:19 | When possible, use memcpy() to and from the mapped region instead of xWrite() and xRead(). (check-in: f8ca5622d9 user: dan tags: experimental-mmap) | |
