Add an application ID for MBTiles tilesets. check-in: 837f6404 user: drh tags: trunk
16:41
Back out the unix VFS changes that seeks to avoid fstat() calls after an unlink(). That change did not clear the problem on FuseFS. check-in: 0617e20a user: drh tags: trunk
15:01
Add the ".eqp" dot-command to the ".help" output in the command-line shell. This was accidently omitted when the ".eqp" command was originally implemented for SQLite 3.8.4 (check-in [e6ecf7337658624]). check-in: b0b4c776 user: drh tags: trunk
12:51

Proposed change to the fix for ticket [1c69be2dafc28b] such that legacy applications that were exploiting the older buggy behavior in SQLite continue to work. Leaf check-in: 401a0ca3 user: drh tags: group-by-name-resolution
2014-06-09
20:39
Avoid an unnecessary initialization of the szFile field of unixFile in the unix VFS. check-in: 6484fb5a user: drh tags: trunk
20:24
Enhance the unix VFS so that it keeps track of the size of unlinked files internally and thus avoids the need to call fstat() on those files, since fstat() does not work reliably on unlinked files on some implementations of FuseFS. check-in: 10707d35 user: drh tags: trunk

Enhance the unix VFS so that it keeps track of the size of unlinked files internally and thus avoids the need to call fstat() on those files, since fstat() does not work reliably on unlinked files on some implementations of FuseFS. Closed-Leaf check-in: c41df393 user: drh tags: omit-fstat-after-unlink
13:11
Modify the %nonassoc directive in lemon so that it generates a run-time error rather than a parsing conflict. This changes is due to a bug report on the mailing list. SQLite does not use the %nonassoc directive in its grammar so this change does not affect SQLite. check-in: 1925f3a0 user: drh tags: trunk
2014-06-06
20:49
Add a test case to ensure that estLog() works for negative numbers. check-in: 813469d9 user: drh tags: trunk
20:20
Make sure the estLog() routine in the query planner handles negative values correctly (always returning 1). Prior to this change, estLog(-1) would return a large number which could throw off the cost computations in the query planner in obscure circumstances. check-in: 75437bee user: drh tags: trunk

Changes to the output of EXPLAIN QUERY PLAN to make it clearer when a query uses the PRIMARY KEY index of a WITHOUT ROWID table. check-in: 9268df30 user: dan tags: trunk
12:03
In the command-line shell, if three or more interrupt signals (control-c) are received in a row without a response from sqlite3_interrupt() then call exit(1) immediately. This allows control-C to interrupt the shell even if it is stuck in a computation or loop that does not involve the VDBE. check-in: b5cde571 user: drh tags: trunk
11:48
Make sure sufficient VDBE registers are allocated for an INSERT...SELECT when there is an idlist on the insert table that includes an explicit rowid. Ticket [e9654505cfda93610585fde5a9bbf2e730c8a8d5] check-in: 9a2dd187 user: drh tags: trunk

Fix arithmetic operators so that they do not change the affinity of their input operands. Ticket [a8a0d2996a]. check-in: 221f8f94 user: drh tags: trunk
11:23
Avoid attempting to mmap memory from an offset that is not a multiple of the system page size on systems with page sizes larger than 32KB. check-in: db7d62c8 user: dan tags: trunk
2014-03-23

Avoid a possible use of an uninitialized variable following an I/O or OOM error. check-in: 641408a1 user: drh tags: trunk
2014-03-22
02:19
Clear the sort-order flags on the KeyInfo object associated with the OP_Compare/OP_Jump of the block-sort logic, in order to make the OP_Jump fully testable. check-in: 9b2838f2 user: drh tags: trunk
01:52
Increase the version number to 3.8.5. check-in: 9760879d user: drh tags: trunk
00:27
Fix the ORDER BY optimization logic so that it will do a block-sort on a partial DESC ORDER BY. This enhancement uncovered a memory leak in pushUntoSorter() which is also fixed. check-in: c36f7461 user: drh tags: trunk
2014-03-21
20:58
Add the ability to use indices for the first few terms of an ORDER BY clause, then sort in batches to handle the later terms. check-in: fa06a6fe user: drh tags: trunk
19:56
Change the names of SRT_DistTable and SRT_Table used by CTE to more meaningful SRT_DistFifo and SRT_Fifo, respectively. Simplify the IgnorableOrderby() macro in the process. check-in: 45d8cc67 user: drh tags: trunk
19:27
Avoid leaking memory in an obscure case where the flattener adds an ORDER BY clause to the recursive part of a recursive query. check-in: 1f413aca user: dan tags: trunk
18:45
Merge the OFFSET-on-query-without-FROM fix from trunk. check-in: 71e9ae72 user: drh tags: orderby-planning
18:16
Fix the OFFSET clause so that it works correctly on queries that lack a FROM clause. Ticket [07d6a0453d4ed8]. check-in: 179ef816 user: drh tags: trunk
15:24
New test case for block-sorting. check-in: e70cfa28 user: drh tags: orderby-planning
2014-03-20
20:56
Merge trunk fixes for "x IN (?)" handling. check-in: eca35871 user: drh tags: orderby-planning
19:04
Remove a testcase() that is now always true due to the "x IN (?)" optimization. Add an ALWAYS() around a conditional in the parser that cannot be false. check-in: d5a1530b user: drh tags: trunk
18:56
Only use the direct-overflow-read optimization if all data from the overflow page in question is being read. check-in: d8e1f75d user: dan tags: overflow-pgno-cache
18:45
Fix the EXPLAIN indenter in the command-line shell to correctly handle NextIfOpen and PrevIfOpen opcodes. check-in: 01944c53 user: drh tags: trunk
17:03
The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is incorrect, as demonstrated by the in4-5.1 test case in this check-in. The "COLLATE binary" that was being added to the RHS of IN was overriding the implicit collating sequence of the LHS. This change defines the EP_Generic expression node property that blocks all affinity or collating sequence information in the expression subtree and adds that property to the expression taken from RHS of the IN operator. check-in: 2ea4a9f7 user: drh tags: trunk
15:14
Fix harmless compiler warnings. check-in: b1435f26 user: drh tags: trunk
14:56
Previous check-in is not quite correct. "x IN (?)" is not exactly the same as "x==?" do to collation and affinity issues. The correct converstion should be to "x==(+? COLLATE binary)". The current check-in fixes this problem and provides test cases. Ticket [e39d032577df69] check-in: 2ff3b25f user: drh tags: trunk
13:26
Convert expressions of the form "X IN (?)" with exactly one value on the RHS of the IN into equality tests: "X=?". Add test cases to verify that statements work correctly on this corner case. Fix for ticket [e39d032577df6942]. check-in: e68b427a user: drh tags: trunk
12:17
Fix an unnecessarily obtuse use of a bitmask flag. check-in: ca314081 user: drh tags: trunk
09:42
Add a test to ensure os_unix.c works with 64KiB OS pages. Closed-Leaf check-in: e3d2be3b user: dan tags: shm-mapping-fix
08:59
Add an experimental fix to avoid attempting to mmap memory from an offset that is not a multiple of the system page size on systems with page sizes larger than 32KB. check-in: 6f3a5c24 user: dan tags: shm-mapping-fix
2014-03-19
23:42
Merge the vdbesort.c optimization from trunk. check-in: e4bfffb9 user: drh tags: orderby-planning
23:24
Fix query planner weights associated with choosing block-sorting. Fix block sorting of tables with collating functions. Fix various test cases. All "veryquick" tests are now passing, though more tests need to be added. check-in: 01afbf97 user: drh tags: orderby-planning
20:01
Avoid some unnecessary calls to sqlite3VdbeRecordUnpack() that were being made when merging data from two or more temp files together in vdbesort.c check-in: 707ea170 user: dan tags: trunk
17:41
Make it possible for block-sort to use the OP_SorterOpen sorter in addition to a generic OP_OpenEphemeral. check-in: 7ce2daaf user: drh tags: orderby-planning
16:56
Fix a problem in the block-sort logic that can arise if the VDBE opcode array is resized while the block-sort logic is being coded. "make test" now runs to completion, though there are still 17 failures. check-in: 62f3a220 user: drh tags: orderby-planning
15:17
Avoid reusing temporary registers in co-routines when doing block-sorting. check-in: 463d921b user: drh tags: orderby-planning
14:30
Make sure the where.c query planner never reports that the number of ORDER BY terms that are satisfied by indices is negative. check-in: b186d8d1 user: drh tags: orderby-planning
14:10
First attempt at getting block-sort to work. This is an incremental check-in. There are many problems still to be worked out. check-in: 59742dd4 user: drh tags: orderby-planning
2014-03-18
20:33
Make the partial-ORDER-BY information in the query planner available to the SELECT code generator. Still doesn't make a difference in the generated code. check-in: e258df23 user: drh tags: orderby-planning
18:59
Adjust the query planner to keep track of the number of ORDER BY terms satisfied. Still doesn't do anything with this information. Some tests fail after this check-in, but all failures are believed to be benign. The failures will be addressed at a later stage. check-in: 59d49b7f user: drh tags: orderby-planning
15:30
Experiments with the optimization of ORDER BY and GROUP BY clauses. check-in: b1509025 user: drh tags: orderby-planning

2014-03-12
19:38
Fix an obscure bug causing sqlite3_close() to fail if there are virtual tables on the disconnect list when it is called. check-in: 6504aa47 user: dan tags: trunk
19:20
Changes to FTS to ensure that it does not access the database from within the xConnect method. check-in: c67a52c3 user: dan tags: trunk

Remove a stray C99-style comment. check-in: f500e87d user: drh tags: overflow-pgno-cache
23:40
Combine the various boolean fields of the BtCursor object into a single bit-vector. This allows setting or clearing more than one boolean at a time and makes the overflow-pgno-cache branch faster than trunk on speedtest1. check-in: 968fec44 user: drh tags: overflow-pgno-cache
20:33
Enable the b-tree cursor object's overflow page-number cache, which is normally enabled only for incr-blob cursors, for all cursors. check-in: da591985 user: dan tags: overflow-pgno-cache

Adjustments to the cost computation for the skip-scan query plan, to take into account the fact that a seek has to occur on each skip. check-in: 0769eebd user: drh tags: trunk
18:03
Attempt to work around MSVC's treatment of __LINE__ as a non-constant value in "Edit and Continue" mode by avoiding the use of __LINE__ when SQLITE_VDBE_COVERAGE is not defined. check-in: 0a5318bc user: drh tags: trunk
12:20
Version 3.8.4 check-in: 530a1ee7 user: drh tags: trunk, release, version-3.8.4

2014-03-07
14:57
Improved comment on the pager.c PERSIST rollback journal delete logic inside of hasHotJournal(). No changes to code. check-in: e5b17a9d user: drh tags: trunk
03:31
Revise change from the previous check-in to clarify the situation when handling open journal files, regardless of journal mode. check-in: 1c318ef3 user: mistachkin tags: trunk
02:29
Avoid calling sqlite3OsDelete() on a file that is open, since this causes Windows to run *very* slowly. Comes up on error recovery in journal_mode=PERSIST. check-in: fdc651e2 user: mistachkin tags: trunk
2014-03-06
18:16
Do not run corruptH.test in mmap mode. check-in: c0d54b4e user: dan tags: trunk

12:36
Remove a branch that is never taken from where.c. check-in: 4a499722 user: dan tags: trunk
02:15
Cosmetic change to the shell in-memory database warning to skip coloring the trailing period. check-in: c87d8e07 user: mistachkin tags: trunk
