| 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) | |
| 14:03 | The sqlite3_snapshot_describe() interface useful for debugging snapshot logic. (Leaf check-in: 3fbfa9a8e8 user: drh tags: sqlite3_snapshot_describe) | |
| 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) | |
| 00:49 | Fix the rendering of the P4_INTARRAY argument to the OP_IntegrityCk opcode in the output of EXPLAIN. (check-in: adc12c83dd 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) | |
| 00:18 | Fix the CSV virtual table extension so that it works when the default character is unsigned. (check-in: 42f0777555 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: 29227d00a9 user: drh tags: trunk) | |
|
2017-09-16
| ||

| ||
| 17:40 | Remove an unnecessary parameter from selectInnerLoop(). (check-in: dd95887f82 user: drh tags: trunk) | |

|
2017-09-14

| 21:12 | Add another test case for the problem fixed by the previous commit. (check-in: 1a7e0b61c8 user: dan tags: trunk) | |
| 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) | |
|

| 12:55 | Disable FTS3 matchinfo() tests that assume a littleEndian platform when running on bigEndian. (check-in: 87ccdf9cbb user: drh tags: trunk) | |
| 00:33 | Improvements to PRAGMA integrity_check for better detection of malformed records. Integrity_check now avoids returning SQLITE_CORRUPT on a corrupt record. Also includes microoptimizations that I stumbled over while working on integrity_check. (check-in: 8525c30c1d user: drh tags: trunk) | |
| 00:13 | PRAGMA integrity_check returns SQLITE_OK even if it encounters corruption while scanning indexes. (Closed-Leaf check-in: 81f62e99f2 user: drh tags: improved-integrity-check) | |

| ||
| 23:58 | Remove use of the rand_s() function (added by [139081bef9f63c3e]) as it appears to cause issues with some third-party DLLs. (check-in: 3a2793aa65 user: mistachkin tags: trunk) | |
| 20:09 | Add the highly-experimental "PRAGMA noop_update=TRUE" command. (check-in: afe45271b9 user: drh tags: begin-concurrent-pnu) | |
| 18:49 | Add the highly-experimental "PRAGMA noop_update=TRUE" command. (Leaf check-in: de2e371757 user: drh tags: pragma-noop-update) | |
