| 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: ff2f5a31a2 user: drh tags: trunk) | |
| 16:56 | Fix over-length source code lines in select.c. No logic changes. (check-in: fd3267ef92 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: 5b9ae69312 user: drh tags: trunk) | |
| 01:58 | Add new routines to simplify dealing with collating sequences in expressions: sqlite3ExprNNCollSeq() and sqlite3ExprCollSeqMatch(). (check-in: 490e488ea9 user: drh tags: trunk) | |
| 01:09 | Indexes on expressions with a COLLATE clause are able to satisfy an ORDER BY with the same COLLATE clause. (check-in: 0413001843 user: drh tags: trunk) | |
| 00:01 | In two places, change the magic number -1 to its proper symbol XN_ROWID. (check-in: 80277d2fc9 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: f5ef2e1bcd user: drh tags: trunk) | |
|
2017-09-25
| ||
| 09:37 | Add an extra snapshot related test case. (check-in: 24a95e1437 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: d71eeaab9e 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: 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) | |
| 00:24 | Update the configure script so that it looks for tclsh8.7 ahead of tclsh8.6. (check-in: 0a12915b37 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: 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) | |
| 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) | |
|
2017-09-20

| 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

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) | |
|
2017-09-13

| 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) | |
