2019-11-03
00:07
The optimization of check-in [9b2879629c34fc0a] is incorrectly reasoned. The WHERE clause of the partial index might not be true if the table of the partial index is the right table of a left join.

Fix a problem in VIEW creation that was introduced by the generated columns feature. (check-in: 9c795c4d user: drh tags: trunk)

"STORED" is not actually a keyword. The parser looks for STORED as an ordinary identifier. (check-in: 167cd574 user: drh tags: trunk)
13:32
In sqlite3GenerateIndexKey(), do not attempt to reuse column values from the previous index if the current index is a partial index as the partial index test may have changed those values. Ticket [a9efb42811fa41ee] (check-in: 17e9f658 user: drh tags: trunk)

16:08
Add another missing column number translation to the foreign key logic. (check-in: 32df5edc user: drh tags: trunk)
15:19
Omit the optimization that reduces the column-count on rowid-table cursors when the table has generated columns, because we do not know what columns the generator expressions might try to access. (check-in: e6c96ed9 user: drh tags: trunk)

2019-10-30
18:50

16:29
Simplify the bytecode generation for SQL function calls such that the OP_Function or OP_PureFunc opcodes are coded directly, rather than using the intermediate OP_Function0 or OP_PureFunc0 - opcodes that are now removed. (check-in: 84e02d77 user: drh tags: trunk)
13:00

2019-10-26
23:51
Remove code from the constraint checker that generates virtual column values with the incorrect time. Turns out the the regular code for all other columns works correctly and so the incorrect special-case code is not actually needed. Fix for ticket [3ea175512444b0d1]. (check-in: 5b4c0f2d user: drh tags: trunk)
18:56

15:26
Disallow fts5 page sizes greater than 65536 bytes - as there are 16-bit offsets used in the page header. Fix for [81a7f7b9]. (check-in: 75775c5a user: dan tags: trunk)
15:08
Remove the "fastfuzztest" makefile target. Use only "fuzztest". (check-in: e17571c7 user: drh tags: trunk)
15:03
New test cases added to test/fuzzdata8.db. (check-in: b68d21e9 user: drh tags: trunk)

13:52
Use the "fuzztest" target in place of "fastfuzztest". (Closed-Leaf check-in: 7129e468 user: drh tags: makefile-cleanup)
13:12
Remove the obsolete "fastfuzztest" target from the makefiles. (check-in: 3d44f1ee user: drh tags: makefile-cleanup)
01:19
Save CPU cycles in sqlite3Prepare() by, among other things, shifting the EXPLAIN column label logic over to sqlite3VdbeMakeReady(). (check-in: 1ca5ef84 user: drh tags: trunk)

2019-10-07
20:36
Disallow page-sizes smaller than 32 bytes in fts5. Also ensure the fts5 integrity-check works even when "PRAGMA reverse_unordered_selects" is true. Fix for [265e935b26]. (check-in: 8ab0aebd user: dan tags: trunk)
20:33

2019-10-05
19:53
Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the database connection uses no shared cache. We might be able to go back and remove this code completely, due to the newer Schema.iGeneration logic, but that will take more analysis. This check-in gives the speed benefit but not the reduction in code size. (check-in: 0b73a092 user: drh tags: trunk)
19:24
Optimization to sqlite3VtabUnlockList() for the common case when there is no work to do. (check-in: fc8d4508 user: drh tags: trunk)

2019-10-03
16:02
Avoid running a couple of tests in affinity2.test as part of the valgrind permutations, as the way floating point computations are simulated by valgrind causes them to fail. (check-in: 7f9a4b60 user: dan tags: trunk)
14:51
Increase the precision of floating point value display in VDBE debugging output. No changes to normally deployed code. (check-in: a561a656 user: drh tags: trunk)

Fix a long-standing problem in fts4 incrmental merge. (check-in: 67da31e2 user: dan tags: trunk)

Remove references to test scripts analyzeA.test and analyzeB.test from permutations.test, since those test modules no longer exist. (check-in: 23948796 user: drh tags: trunk)

The nodeReaderInit() function in FTS3 may not assume that the node is non-empty. (check-in: 361eb2f6 user: drh tags: trunk)

18:28
Add missing comment to constant definitions. (check-in: 661a3789 user: drh tags: trunk)
16:14
Improvements to a comment. No code changes. (check-in: 1a3671c7 user: drh tags: trunk)

15:15
Alternative implementation of the previous check-in which is testable. (check-in: 102ef644 user: drh tags: trunk)
15:01
Fix sqlite3ExprCompare() so that it ignores differences in the Expr.iTable field for IN operators, as otherwise it can lead to false negatives, which is usually harmless, but can cause problems for an assert() in the window function logic. (check-in: 6a204b19 user: drh tags: trunk)
2019-09-26
20:57
More minor test file fixes. (check-in: 352878fe user: dan tags: trunk)

Omit the sqlite3IntTokens array constant for a code simplification. (check-in: f907395e user: drh tags: trunk)

When a scalar subquery has a pre-existing "LIMIT X" then change it to "LIMIT X<>0" rather than just "LIMIT 1" so that if X is 0 the limit will still be zero. Ticket [99cd4807dc03f178]. Test cases in TH3. (check-in: 82e5dcf5 user: drh tags: trunk)

2019-09-17
21:28
Do not change the OP_String8 opcode into OP_String until *after* any necessary encoding conversions are accomplished. Otherwise, a rerun of the prepared statement after an OOM can result in errors. Test case in TH3. (check-in: 8efd6259 user: drh tags: trunk)

03:16
Fix the instr() SQL function so that it makes a copy of its argument before changing the datatype, since the datatype affects processing. Also fix the sqlite3_value_text() routine so that it always works even for values obtained form sqlite3_value_dup(). Ticket [587791f92620090e] (check-in: 3fb40f51 user: drh tags: trunk)
