| 17:05 | Add new interfaces sqlite3_result_pointer(), and sqlite3_value_pointer() and use them to transfer the eponymous FTS3 column pointer to the snippet() and offsets() routines. Cherrypick from commit [8201f4e1] on branch-3.18. (check-in: 553a923c82 user: dan tags: branch-3.19) | |

2018-03-06
| ||
| 11:49 | Avoid running a couple of tests in crash8.test that depend on the presence of the journal file if running on an F2FS file-system that does not require a journal file. Cherrypick of [797e02e0]. (check-in: eeedfc74d2 user: dan tags: branch-3.19) | |
|
2018-02-02
| ||
| 08:14 | In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically. The only time this matters is when the file was 0 bytes in size to start with. Cherrypick of [b3122db154]. (check-in: 22a228edad user: dan tags: branch-3.19) | |
| 08:08 | Update a couple of test scripts so that they work on F2FS file-systems that support atomic transactions. Cherrypick of [49e58e645e]. (check-in: 1b39467927 user: dan tags: branch-3.19) | |

|
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: 8d2a1cca61 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: 2c03d8b8f0 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: 403b88a894 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: c7a5880d6d user: dan tags: begin-concurrent) | |
| 10:49 | Merge latest trunk changes into this branch. (check-in: 307b802e86 user: dan tags: begin-concurrent) | |

| 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: 5d03c738e9 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: fa3f5bcc23 user: drh tags: trunk) | |
| 19:08 | Fix harmless UB in the ICU extension. (check-in: 68e9a840d9 user: drh tags: trunk) | |

| 13:11 | Fix a potential use of an uninitialized pointer in RTree following an OOM error. (check-in: fd4ec0cdbd 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: 65765222ef 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: f8b1c64d3e 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: 1b2de41453 user: drh tags: trunk) | |
| 18:08 | Fix a typo in the MSVC makefile. (Closed-Leaf check-in: 3235835bab 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: d4a30b91f9 user: dan tags: mmap-warm) | |
| 13:16 | Minor simplification of error message generation during compound query code generation. (check-in: a944719314 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: 74f399d81f user: drh tags: trunk) | |
| 08:51 | Merge latest trunk changes with this branch. (Leaf check-in: 2e57335081 user: dan tags: shared-mapping-hack) | |

|
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: 29227d00a9 user: drh tags: trunk) | |
|
2017-09-16

| 20:41 | Avoid an out-of-bounds read that can be caused by a specially constructed journal file. (check-in: cf5bf42cad user: dan tags: trunk) | |
| 02:36 | Avoid an out-of-bounds read on a recovery attempt using a carefully crafted database and rollback journal with mismatched page sizes. The test case for this is in TH3. (check-in: 378afa1638 user: drh tags: trunk) | |
