I was a little concerned about this check-in. Though I could not generate a failure myself, I thought it was risky. I checked it in for further testing. Then, overnight, OSSFuzz found a failure case for me. So the change is now moved out into a deadend branch. Was: Use OP_SCopy rather than OP_Copy to transfer results from a co-routine to its consumer. This undoes an earlier fix for ticket [98825a79ce] by check-in [ec6a06246e] because that problem no longer occurs due to WHERE clause push-down. (Closed-Leaf check-in: 0926df09 user: drh tags: mistake)

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)
01:09
Indexes on expressions with a COLLATE clause are able to satisfy an ORDER BY with the same COLLATE clause. (check-in: 04130018 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)
2017-09-22
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)
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)
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
18:47
Size and performance optimization on sqlite3VdbeMemGrow(). (check-in: 4b3f7eac user: drh tags: trunk)
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)
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)
15:38
Improved the header-comment documentation on sqlite3ExprCodeExprList(). No changes to code. (check-in: 5dc3ecb5 user: drh tags: trunk)
15:17
Optimization to the ExprList object to make it slightly smaller and faster. (check-in: 4da49a95 user: drh tags: trunk)
14:36

20:41
Avoid an out-of-bounds read that can be caused by a specially constructed journal file. (check-in: cf5bf42c 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: 378afa16 user: drh tags: trunk)
2017-09-13
20:20
Test case update due to PRAGMA integrity_check enhancements in [8525c30c]. No changes to code. (check-in: 43c6023b user: drh tags: trunk)
12:55
Disable FTS3 matchinfo() tests that assume a littleEndian platform when running on bigEndian. (check-in: 87ccdf9c 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: 8525c30c user: drh tags: trunk)
00:13
PRAGMA integrity_check returns SQLITE_OK even if it encounters corruption while scanning indexes. (Closed-Leaf check-in: 81f62e99 user: drh tags: improved-integrity-check)
00:01
Fix test script comment. No changes to code. (check-in: a5a19492 user: mistachkin tags: trunk)
2017-09-12
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: 3a2793aa user: mistachkin tags: trunk)
15:05
Fix an error in [b22cdd67] that can cause a negative infinity to be (rarely) reported as a positive infinity. (check-in: 9780b23c user: drh tags: trunk)
13:27
Changes to (hopefully) get the build working with recent Intel compilers. (check-in: b22cdd67 user: drh tags: trunk)
00:24
Make sure all connections are closed in the pragma.test script. Test change only - no changes to code. (check-in: d7b7f038 user: drh tags: trunk)
2017-09-11
23:46
New test case for ticket [b899b6042f97f52d]. (check-in: 9d91ee5e user: drh tags: trunk)
