| 14:24 | The simplification to sqlite3SelectExpand() in last night's [3a4ffb21] check-in was not completely correct. This adjustment is needed for correct OOM handling in some configurations. check-in: c5ad5e16 user: drh tags: trunk | |
| 03:24 | Simplification to the logic that computes column type names. Update: Does not work in all configurations. Closed-Leaf check-in: f10ece96 user: drh tags: does-not-work | |

| 13:20 | Avoid using lookaside memory for persistent virtual table structures. check-in: d815f255 user: drh tags: trunk | |
| 02:52 | The query planner now always prefers to implement a FROM-clause subquery using a co-routine rather than flattening the subquery into the outer query. check-in: c9104b59 user: drh tags: trunk | |
| 02:32 | Improvements to a comment in lempar.c. No code changes. check-in: 8000d230 user: drh tags: trunk | |

| 12:12 | Better names for subqueries in EXPLAIN comments. check-in: 04ef40a8 user: drh tags: trunk | |
|
2017-09-28
| ||
| 20:06 | Do not flatten subqueries that contain an ORDER BY or GROUP BY clause and can be implemented using a co-routine. check-in: 042d655d user: drh tags: prefer-coroutine-sort-subquery | |
| 17:29 | Remove the (undocumented) query-planner control that prevents a "SELECT ALL" subquery in FROM clause from being implemented as a co-routine. This control was added by [a29e117d7ec], where it was called a "stop-gap". check-in: ff2f5a31 user: drh tags: trunk | |
| 16:56 | Fix over-length source code lines in select.c. No logic changes. check-in: fd3267ef user: drh tags: trunk | |
| 13:47 | Fix an issue introduced by check-in [4cd2a9672c59] (2017-03-03) that could allow a negative value in the 3rd parameter to memmove() when defragmentPage() is called on a btree page with a corrupted freeblock list. The corruption is now detected early and results in an SQLITE_CORRUPT return before the memmove() is reached. check-in: 5b9ae693 user: drh tags: trunk | |
| 01:58 | Add new routines to simplify dealing with collating sequences in expressions: sqlite3ExprNNCollSeq() and sqlite3ExprCollSeqMatch(). check-in: 490e488e user: drh tags: trunk | |

| 00:01 | In two places, change the magic number -1 to its proper symbol XN_ROWID. check-in: 80277d2f user: drh tags: trunk | |
|
2017-09-27
| ||
| 16:51 | Disable tests for the LIKE optimization when ICU is enabled, since the LIKE optimization only works for the built-in LIKE operator and ICU overrides the built-in. check-in: f5ef2e1b user: drh tags: trunk | |
|
2017-09-25
| ||
| 09:37 | Add an extra snapshot related test case. check-in: 24a95e14 user: dan tags: trunk | |
|
2017-09-23
| ||
| 07:46 | Experimental change so that snapshot transactions always lock the wal file - preventing writers or truncate-checkpointers from wrapping it. Closed-Leaf check-in: d71eeaab user: dan tags: snapshots-lock-wal | |
|
2017-09-22
| ||
| 20:18 | Merge in all the trunk enhancements of the previous 7 months. The LIKE optimization has stopped working when there is an ESCAPE - that problem will be addressed in a subsequent check-in. Leaf check-in: 8d2a1cca user: drh tags: est_count_pragma | |
| 16:23 | Use the updated Win32 VFS semantics for winOpen from check-in [5d03c738e9] for WinRT, et al, as well. check-in: 2c03d8b8 user: mistachkin tags: trunk | |
| 12:52 | Partial backout of check-in [e0af9a904076]. It turns out we do need some extra space at the end of the record blob as an overrun area to use when decoding a maliciously malformed record. check-in: 403b88a8 user: drh tags: trunk | |
| 11:09 | Cherrypick [ec37ad6d08] into this branch. With this patch, if SQLITE_SHARED_MAPPING is defined at build-time SQLite will use a single memory mapping for multiple connections to the same database file within a single process. check-in: c7a5880d user: dan tags: begin-concurrent | |
| 10:49 | Merge latest trunk changes into this branch. check-in: 307b802e user: dan tags: begin-concurrent | |
| 00:24 | Update the configure script so that it looks for tclsh8.7 ahead of tclsh8.6. check-in: 0a12915b user: drh tags: trunk | |
|
2017-09-21
| ||
| 20:43 | In the Windows VFS, when trying to open a database file read/write, if it fails check to see if the file exists and is read-only and immediately fall back to a read-only open attempt, rather than running the AV retry loop. check-in: 5d03c738 user: drh tags: trunk | |
| 20:03 | In the Windows VFS, do not emit an SQLITE_CANTOPEN error log message when falling back from SQLITE_OPEN_READWRITE to SQLITE_OPEN_READONLY. Wait until the open fails completely. check-in: fa3f5bcc user: drh tags: trunk | |
| 19:08 | Fix harmless UB in the ICU extension. check-in: 68e9a840 user: drh tags: trunk | |
| 14:03 | The sqlite3_snapshot_describe() interface useful for debugging snapshot logic. Leaf check-in: 3fbfa9a8 user: drh tags: sqlite3_snapshot_describe | |
| 13:11 | Fix a potential use of an uninitialized pointer in RTree following an OOM error. check-in: fd4ec0cd user: drh tags: trunk | |
| 10:24 | Fix a bug in tool/mksourceid.c: The mksourceid.c program was incorrectly including the "# Remove this line" line of the Fossil-generated "manifest" file in the SHA3 hash. That means that all SQLITE_SOURCE_IDs for trunk versions going back to check-in [30966d56] (2017-08-22) are incorrect. check-in: 65765222 user: drh tags: trunk | |
| 01:04 | Revert one performance improvement changes from check-in [3b3e32d4cd07] as it was causing a reference to an uninitialized value. check-in: f8b1c64d user: drh tags: trunk | |
| 00:49 | Fix the rendering of the P4_INTARRAY argument to the OP_IntegrityCk opcode in the output of EXPLAIN. check-in: adc12c83 user: drh tags: trunk | |
|
2017-09-20

| 18:07 | The BLOB returned by sqlite3VdbeMemFromBtree() does not need to be zero-terminated. check-in: e0af9a90 user: drh tags: trunk | |
| 17:49 | Small size and performance optimization in the bytecode engine. check-in: 3b3e32d4 user: drh tags: trunk | |
| 10:47 | Improved resolution of large integer values in "CAST(x AS NUMERIC)". check-in: 7f2bd4ff user: drh tags: trunk | |
| 09:09 | Updates to the "lemon.html" document received from Andy Goth. check-in: 5b2002f3 user: drh tags: trunk | |
|
2017-09-18
| ||
| 18:17 | Add the sqlite3_mmap_warm() function as an extension in the ext/misc/mmapwarm.c source file. check-in: 1b2de414 user: drh tags: trunk | |
| 18:08 | Fix a typo in the MSVC makefile. Closed-Leaf check-in: 3235835b user: drh tags: mmap-warm | |
| 16:28 | Add extension "mmapwarm.c". Provides function sqlite3_mmap_warm(), used to "warm up" the memory mapping used by SQLite in mmap mode to access db file content. check-in: d4a30b91 user: dan tags: mmap-warm | |
| 13:16 | Minor simplification of error message generation during compound query code generation. check-in: a9447193 user: drh tags: trunk | |
| 09:40 | The out-of-bounds read on recovery fix of check-in [378afa16381a222a] caused problems for some corner-case error conditions. This alternative fix appears to work better. check-in: 74f399d8 user: drh tags: trunk | |
| 08:51 | Merge latest trunk changes with this branch. Leaf check-in: 2e573350 user: dan tags: shared-mapping-hack | |
| 00:18 | Fix the CSV virtual table extension so that it works when the default character is unsigned. check-in: 42f07775 user: drh tags: trunk | |
|
2017-09-17
| ||
| 19:45 | Do not make the assumption (as check-in [4da49a95c0f07] incorrectly did) that the ExprList returned by sqlite3ExprListDup() would never be passed into sqlite3ExprListAppend(). Include a new test case that shows this sometimes does happen. check-in: 29227d00 user: drh tags: trunk | |
|
2017-09-16
| ||
| 20:58 | Simplify the sqlite3VdbeGet() routine. Smaller, faster, and easier to maintain. check-in: 5dbb255a user: drh tags: trunk | |
|
2017-09-15
| ||
| 17:40 | Remove an unnecessary parameter from selectInnerLoop(). check-in: dd95887f user: drh tags: trunk | |
