2018-12-31
17:58
Small changes to the OP_OpenEphemeral opcode to improve testability. check-in: f856676c user: drh tags: trunk
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
20:47
Merge latest begin-concurrent changes with this branch. check-in: 1625887c user: dan tags: begin-concurrent-wal2
20:42
Fix a problem causing a corrupt pager-cache if an OOM or IO error was encountered while committing a concurrent transacation. check-in: 48ca30f9 user: dan tags: begin-concurrent
16:34
Increase coverage provided by permutation "coverage-wal" on this branch. check-in: f664f940 user: dan tags: begin-concurrent-wal2
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
00:30
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

15:04
Here is the beginnings of an effort to factor out the implementation of scalar subqueries to be implemented as subroutines at the end of the main body of bytecode, after the jump back to the OP_Init opcode. This is an incremental check-in that contains only preliminary changes. check-in: 50e5f390 user: drh tags: factor-out-scalar-subselect
14:23

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

13:34
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

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

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

2018-12-19
17:05
Add new interfaces sqlite3_result_pointer(), and sqlite3_value_pointer() and use them to transfer the eponymous FTS3 column pointer to the snippet() and offsets() routines. Cherrypick from commit [8201f4e1] on branch-3.18. check-in: 553a923c user: dan tags: branch-3.19
16:03
