2019-01-18
21:17
Fix a memory leak introduced by [55c5d72a]. (check-in: fbd681dc user: dan tags: trunk)
21:12

14:53
Use the full 64-bit integer value in the argument to randomblob(). (check-in: 05df5f7a user: drh tags: trunk)
2019-01-17
20:19
Disable the xfer-optimization if the two tables have the same root page due to schema corruption. (check-in: f31b3bd2 user: drh tags: trunk)

15:40
Revamp the SrcList allocator routines to be methods of Parse instead of being methods of the "sqlite3" object, so that they can leave better error messages when the SrcList object grows too large. (check-in: df08d472 user: drh tags: trunk)
14:34
Limit the size of SrcList objects to 200 entries (compile-time configurable using -DSQLITE_MAX_SRCLIST=n). The maximum number of tables in a join has always been 64, so this is not a real constraint on capability.

Fix a problem with querying a corrupt fts3 database. (check-in: 65e50706 user: dan tags: trunk)
13:32
When parsing a corrupt record using sqlite3VdbeRecordUnpack(), make sure that the resulting UnpackedRecord object is completely initialized, to avoid (harmless) MSAN warnings. (check-in: ddc3697e user: drh tags: trunk)

2019-01-13
20:23
In dbfuzz2, avoid using a malloc in the LLVMFuzzerInitialize() initializer routine, so that no memory leaks are reported. Also, show the version of SQLite being used when the -v option is on. (check-in: 824f9324 user: drh tags: trunk)
20:17
Relax the minimum size database file constraint on the dbtotxt utility program. (check-in: 97e723d7 user: drh tags: trunk)

01:12
Fix the fts3DecodeIntArray() function so that it will not read off the end of the buffer it is handed. Any unread integers are set to zero. (check-in: 666cf8f6 user: drh tags: trunk)
2019-01-09
21:12

15:57
For SQLITE_ENABLE_PREUPDATE_HOOK builds, disable the optimization for a REPLACE command on a WITHOUT ROWID table with no indexes, triggers or foreign key constraints that causes SQLite to clobber any existing row without separately checking for it.

Additional steps to help ensure that scalar subqueries are only evaluated once even if they are used in multiple places within the query. This fixes a performance regression reported on the mailing list and caused by check-in [531eca6104e41e43] which was a fix for ticket [787fa716be3a7f650c]. Think of this check-in as an improved fix for that ticket. (check-in: e1303193 user: drh tags: trunk)
20:13
Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization. Put an assert in place of the optimization to detect if the need for this optimization ever returns. (Closed-Leaf check-in: 4fcdc7a2 user: drh tags: reuse-subqueries)

16:36
Fix the OP_OpenEphemeral opcode in the bytecode engine so that if it is called a second or subsequent time, it merely clears the existing table rather than creating a new one. Proposed fix for ticket [d0866b26f83e9c55e30de0821f5d]. (check-in: 4678cb10 user: drh tags: trunk)
2018-12-29
14:23
Additional small performance increase and size reduction to the sqlite3VdbeMakeLabel() mechanism. (check-in: 1bdee199 user: drh tags: trunk)
02:26
A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer memory allocations by deferring memory allocation until sqlite3VdbeResolveLabel() is called, at which point the code generator has a better idea of how big the relocation table needs to be. The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of Vdbe*. (check-in: 4a0929ac user: drh tags: trunk)

Increase the number of parameters to sqlite3WhereCodeOneLoopStart() to encourage the compiler to inline that routine within sqlite3WhereBegin(). This gives a performance improvement. (check-in: 3c2ad0e9 user: drh tags: reuse-subqueries)
2018-12-24
20:21
Improvements to EXPLAIN QUERY PLAN formatting. The MULTI-INDEX OR now shows a separate "INDEX" subtree for each index. SCALAR SUBQUERY entries provide a subquery number that is related back to the .selecttrace output. (check-in: 7153552b user: drh tags: reuse-subqueries)
20:00
Add a few more test cases to walfault2.test and walvfs.test. (check-in: 3873941c user: dan tags: trunk)

Change the way a comparison used to detect corrupt databases in fts3 is done to avoid potential pointer overflow in 32-bit builds. (check-in: 95a9a39f user: dan tags: trunk)
12:09
Do not generate subroutines for non-static SELECT and EXISTS expressions. Fix up some test cases to account for the minor changes in EXPLAIN QUERY PLAN output. (check-in: 06de44ec user: drh tags: reuse-subqueries)
11:55
Prevent the use of subroutines to implement the RHS of IN operators within CHECK constraints. (check-in: 6b24d3fb user: drh tags: reuse-subqueries)
02:34
Experimental code that tries to put the computation of subqueries inside a subroutine, and reuse that subroutine if the same subquery is evaluated more than once. Current code does not work for CHECK constraints. (check-in: 6c44838a user: drh tags: reuse-subqueries)
2018-12-23
21:27
Split the code generation for the RHS of IN operators and for SELECT and EXISTS expressions into two separate subroutines, because there is now little commonality between those to functions. This is intended to help make the code easier to read and maintain. (check-in: 2b6494b1 user: drh tags: trunk)

00:34
The OP_Eq and OP_Ne operators have a special P5 value SQLITE_NOTNULL that asserts that the values are not null. Except that is not always true for a corrupt database. Adjust the assert() and add a testcase() to make this point clear. (check-in: a3fdb2c7 user: drh tags: trunk)
2018-12-21
22:11
Update the dbtotxt utility program so that it does not output characters that are special to TCL, thus making the output of dbtotxt easier to insert into test scripts. (check-in: 48438bb3 user: drh tags: trunk)
22:08
Improved detection of shadow table corruption in RTREE. (check-in: b39bf435 user: drh tags: trunk)
20:18
Add new sqlite3_prepare_v3() flag SQLITE_PREPARE_NO_VTAB, for preparing statements that are not allowed to use any virtual tables. Use this to prevent circular references in triggers on virtual table shadow tables from causing resource leaks. (check-in: da587d18 user: dan tags: trunk)
19:55
Use SQLITE_PREPARE_NO_VTAB in rtree as well. (Closed-Leaf check-in: 82a2ae71 user: dan tags: prepare-no-vtab)

Prevent an infinite loop in rtree that can result from a corrupt shadow table. (check-in: 08566718 user: drh tags: trunk)
15:13
Fix the RTree extension so that it correctly ignores constraints that it does not understand, even if they are against a dimension column. (check-in: ed8531e5 user: drh tags: trunk)
13:30
In RTREE, turn an assert() into an if() because the condition can sometimes be false when dealing with a corrupt database. (check-in: 99bce435 user: drh tags: trunk)

Do not set the Cursor.seekOp test variable in the OP_NotExists opcode. This is a change to test logic only and does not affect deliverable builds. (check-in: 98f34307 user: drh tags: trunk)
17:32
Fix a bug in the code that detects self-referencing rows as part of foreign key processing. Fix for [50d2a6c2]. (check-in: 16fff053 user: dan tags: trunk)

Back out the expansion of the temporary buffer size from [32754ca6f86da816] and replace it with an explicit test for buffer overreads. (check-in: 8ba3d9f3 user: drh tags: trunk)
16:00
Avoid a buffer overread in ptrmapPutOvflPtr() that can occurs in a corrupt database file that has large entries and uses autovacuum. (check-in: f8b781cf user: drh tags: trunk)

Fix a harmless compiler warning in Sessions. (check-in: fc9791ea user: drh tags: trunk)
13:35
Expand the size of the temporary page used during btree rebalancing by a few bytes, to avoid problems with small buffer overreads that can occur on corrupted database files. (check-in: 32754ca6 user: drh tags: trunk)
13:18
When saving the position of a cursor at the b-tree layer, allocate a few extra bytes at the end of the buffer used to save the key. Otherwise, if the key is corrupt, the code that restores the cursor position may overread the buffer by a little. (check-in: 160b1e31 user: dan tags: trunk)
11:16
Fix a problem with bytecode generation when a query involves two or more indexes on expressions connected by OR. Ticket [d96eba87698a428c1ddd0790ea04] (check-in: 7e4ed8b5 user: drh tags: trunk)
