Fix a problem building with SQLITE_OMIT_WAL defined. check-in: 373b0ace user: dan tags: trunk
19:12
Fix the command-line shell so that the ".schema --indent" command does a better job of dealing with \r\n in the middle of a CREATE statement in the schema. check-in: 4258fb57 user: drh tags: trunk
11:29
Disable the delta checksum verification in RBU by default. Reenable it using -DRBU_ENABLE_DELTA_CKSUM, if desired. check-in: d22c99b6 user: drh tags: trunk

Amend recent changes to busy.test to avoid failing with SQLITE_ENABLE_STAT4 builds. check-in: 9ff49441 user: dan tags: trunk
12:06
Turn restriction 20 on the query flattener into an assert since the situation restricted can no longer occur because of the more aggressive use of co-routines. check-in: 4464f40c user: drh tags: trunk
10:39
Add tests to verify that the busy-handler is invoked correctly when processing "PRAGMA optimize" and ANALYZE commands. check-in: fb83c3d8 user: dan tags: trunk

19:53
Simplify the computation of types on columns of a view. check-in: 772b0db1 user: drh tags: trunk
18:35
Do not enable SELECT tracing with -DSQLITE_DEBUG. Require the -DSQLITE_ENABLE_SELECTTRACE compile-time option to enable SELECT tracing. check-in: f5c39583 user: drh tags: trunk

Fix the sqlite3_column_decltype() interface to return the correct datatype when the value comes through a CTE. check-in: 966438bd user: drh tags: trunk
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
03:01
Do not compute column and row size estimates for the transient Table objects associated with the result set of a SELECT statement, since those estimates are never used for anything constructive. check-in: e4342fd4 user: drh tags: trunk
2017-10-02
23:50
Mark a single branch within sqlite3SelectExpand() as an optimization. check-in: 3a4ffb21 user: drh tags: trunk
23:30

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

More details in the header comment of pushDownWhereTerms(). No changes to code. Closed-Leaf check-in: 92848623 user: drh tags: prefer-coroutine-sort-subquery
10:50
Make sure the SQLITE_Stat34 optimization switch is always 0x800, a value which is hard-coded in the TH3 test suite. check-in: 6aed4ea3 user: drh tags: prefer-coroutine-sort-subquery
01:25
Fix unreachable conditionals and revise a testcase that was made obsolete by the changes on this branch. check-in: 71f0adf7 user: drh tags: prefer-coroutine-sort-subquery
2017-09-29
22:13
Always render a subquery that is not part of a join as a co-routine. check-in: 6b1651d7 user: drh tags: prefer-coroutine-sort-subquery
16:08
Merge the query flattener comment improvements from trunk. check-in: f62cd4d9 user: drh tags: prefer-coroutine-sort-subquery
16:07
Clean up the comments on the query flattener to more clearly and accurately express the conditions under which the flattener is able to run. check-in: 0840f9f8 user: drh tags: trunk
14:31
Merge changes from trunk. check-in: 06f432fb user: drh tags: prefer-coroutine-sort-subquery
12:44
Make sure the 6th parameter to the authorizer callback for view subqueries has the correct view name. check-in: 2a45bbc9 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
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

17:49
Small size and performance optimization in the bytecode engine. check-in: 3b3e32d4 user: drh tags: trunk
10:47
