16:11
Update dbfuzz2 to set a maximum database size of 100MiB by default, but with the new --max-db-size N option to change that limit. check-in: 21d6bb78 user: drh tags: trunk

14:07

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.

2019-01-14
20:44
Add scalar function "prefix_length()" to ext/misc/prefixes.c. check-in: 0bf15505 user: dan tags: trunk
19:13
Fix a problem causing some Tcl test cases to fail with errors like "expected: [<multiline-whitespace>], got: []". check-in: 11b8a4cb user: dan tags: trunk
16:16

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

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.

20:39
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Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization.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

07:46
Fix a null-pointer dereference that could occur in fts5 with a corrupt database. check-in: b0a49d5e user: dan tags: trunk
02:16
Fix a problem in which nested CTEs with the same table name trick the code generator into thinking they are the same CTE, which then tries to use the manifest them both into the same transient table. check-in: 202dd033 user: drh tags: trunk

In the treeview debugging output, provide additional details for the Table object associated with each FROM clause term. check-in: 11d4682d 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

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
2018-12-22
20:32
Improve the coverage of wal.c provided by the "coverage-wal" test permutation. check-in: 62314851 user: dan tags: trunk

16:14
Fix one more instance of excess whitespace in test result strings. check-in: c064964d user: drh tags: trunk

Fix cut-and-paste error in test file fts4umlaut.test. check-in: cad5da1b user: dan 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

Add tests for the use of SQLITE_PREPARE_NO_VTAB in fts5. check-in: 19996120 user: dan tags: prepare-no-vtab
19:29
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: 25666e3d user: dan tags: prepare-no-vtab

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
11:53
Remove an assert() that could fail on a corrupt db from fts3_write.c. check-in: 4cdcda40 user: dan tags: trunk
2018-12-20
22:08
