53 check-ins using file test/window1.test version a96a80bd

2018-12-29
20:47
Merge latest begin-concurrent changes with this branch. (check-in: 1625887c user: dan tags: begin-concurrent-wal2)
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)
2018-12-28
21:40
Merge performance enhancements and other patches. (Leaf check-in: 44e1b55a user: drh tags: factor-out-scalar-subselect)
21:32
Merge performance enhancements from trunk. (check-in: 0f1b9ff9 user: drh tags: reuse-subqueries)
20:48
Faster allocation of new sqlite3_stmt objects. (check-in: 891f1f72 user: drh tags: trunk)
20:14
Move the nOpAlloc field from Parse into Vdbe to avoid an extra pointer deference on the fast path in sqlite3VdbeAddOp3(). (check-in: 8f10efc2 user: drh tags: trunk)
19:23
Merge patches and enhancements from trunk. (check-in: da53f3d3 user: drh tags: reuse-subqueries)
18:09
Fix another problem with loading the structure record from a corrupt fts5 database. (check-in: c4d44542 user: dan tags: trunk)
17:45
Fix a problem causing the sqlite_master entry corresponding to a virtual table to be removed by a DROP TABLE even if the call to the vtabs xDestroy() method failed. (check-in: 0140f6db user: dan tags: trunk)
16:20
Add new test file wal2rollback.test to this branch. (check-in: 85a376fc user: dan tags: wal2)
14:33

Merge latest wal2 changes with this branch. (check-in: ea96001e user: dan tags: begin-concurrent-wal2)
16:55
Modify the btree02.test module so that it does not depend on whether TCL interprets a value as a string or as an integer. (check-in: d9e4f957 user: drh tags: trunk)
16:49
Increase test coverage of wal.c provided by permutation "coverage-wal" on this branch. (check-in: 2f7f893a user: dan tags: wal2)
15:36
Fix another problem in fts5 caused by a corrupt schema record. (check-in: ff45f9dd user: dan tags: trunk)
13:52
Fix the filename normalization in the dbtotxt utility program. (check-in: 29a00a05 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)
2018-12-26
20:42
Improve testing of the wal.c changes on this branch. (check-in: 63483e22 user: dan tags: wal2)
19:10
Merge latest trunk changes with this branch. (check-in: 404f9d99 user: dan tags: wal2)
18:34
Update the coverage-wal permutation to cover branches enabled by SQLITE_ENABLE_SNAPSHOT. (check-in: 6821c61f user: dan tags: trunk)
17:49
Add a few more test cases to walvfs.test. (check-in: 14a64df3 user: dan tags: trunk)
16:57
Avoid an "uninitialized value read" problem in fts5 that can occur with a corrupt database. (check-in: 6cae81cd user: dan tags: trunk)
16:04
Fix a problem with handling corrupt databases in the fts5 integrity-check function. (check-in: 9bad745d user: dan 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)
14:15
Fix a problem with corrupt fts3 database detection introduced by [95a9a39f]. (check-in: c80bb15b user: dan tags: trunk)
12:50
Fix a problem with the CSV extension when it uses the "header" option on a real file. (check-in: 7acaed08 user: drh tags: trunk)
2018-12-25
11:17
Fix a typo in a comment that is used to generate session documentation. (check-in: a1f50d57 user: drh tags: trunk)
00:15
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)
19:59
Change another fts5 assert() that may fail with a corrupt database to an assert_nc(). (check-in: d9653380 user: dan tags: trunk)
18:51
Add test cases to test file walvfs.test. (check-in: d697f6f3 user: dan tags: trunk)
18:10
Always include OP_Explain opcodes in the bytecode when SQLITE_DEBUG is enabled. (check-in: d8c1235c user: drh tags: trunk)
15:22
Copy some extra test infrastructure from the mutexfree-shmlock branch to trunk. (check-in: 883337ff user: dan tags: trunk)
15:15
Merge latest trunk with this branch. (Leaf check-in: 606b1ead user: dan tags: mutexfree-shmlock)
14:30
Restore a line of code that was previously commented out for debugging. (check-in: e53781f5 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)
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)
19:54
Catch another case of a corrupted structure record in fts5. (check-in: fb17fea4 user: dan tags: trunk)
19:09
Change a faulty assert() in fts5 that could fail on a corrupt db to an if() statement. (check-in: 1daaba9f user: dan tags: trunk)
16:14
Fix one more instance of excess whitespace in test result strings. (check-in: c064964d user: drh tags: trunk)
15:46
Remove unnecessary whitespace from testcase result strings. (check-in: ad70f03c user: drh tags: trunk)
