2017-05-30
18:34
Change sqlite3BtreeNext() and sqlite3BtreePrevious() so that they return SQLITE_DONE if they have already reached the end (or beginning) of the table. This gives a performance increase and size reduction. (check-in: e972a386 user: drh tags: trunk)
18:14
Omit a test of codepoint 0x202F (non-break narrow space) from the fts3 ICU tests. Different versions of ICU apparently handle this obscure codepoint slightly differently. (check-in: 69ae6889 user: dan tags: trunk)

13:09
Correctly initialize the iSelectId of FROM clause terms that are a self join of a reused materialized subquery. Without this, the EXPLAIN QUERY PLAN output for the query will identify the subquery using the uninitialized (and arbitrary) iSelectId. (check-in: 43c9ae37 user: drh tags: trunk)
03:48
Improve shell help text for the '.open' command. (check-in: 7cc940a9 user: mistachkin tags: trunk)

Version 3.19.2 (check-in: edb4e819 user: drh tags: release, branch-3.19, version-3.19.2)
11:39
The SQLITE_EXTRA_IFNULLROW compile-time option causes OP_IfNullRow opcodes to be issued for references to the right-hand side table of *any* flattened join, not just LEFT JOINs. This puts extra stress on the OP_IfNUllRow opcodes for testing purposes. (check-in: 1a074c8a user: drh tags: branch-3.19)
00:28
The TK_IF_NULL_ROW expression node must be treated as a variable that references the table Expr.iTable. Proposed fix for ticket [7fde638e94287d2c]. (check-in: b30a364a user: drh tags: branch-3.19)
00:12
Increase the version number to 3.19.2 since ticket [7fde638e94287d2] is going to necessitate another patch release. (check-in: c315727a user: drh tags: branch-3.19)
00:08
The TK_IF_NULL_ROW expression node must be treated as a variable that references the table Expr.iTable. Proposed fix for ticket [7fde638e94287d2c]. (check-in: 77fc2301 user: drh tags: trunk)

15:33
Disable the LEFT JOIN flattening optimization for aggregate queries, as it does not currently work. Further fix for ticket [cad1ab4cb7b0fc344]. (check-in: 05ada741 user: drh tags: branch-3.19)
15:21

12:44
Ensure that the expression rewriter inside the query flattener decends into the substructure of the TK_IF_NULL_ROW operator. This is a continuation of the fix for ticket [cad1ab4cb7b0fc344]. (check-in: 28d2902d user: drh tags: branch-3.19)
12:36

01:35
Change the version number to 3.19.1. (check-in: 16656b8f user: drh tags: branch-3.19)
01:30
Remove a surplus semicolon, which was harmless on gcc and clang but caused compile-time errors on msvc. This only comes up using the encryption extension. (check-in: 4510d55d user: drh tags: branch-3.19)
01:29
When flattening a query, make sure iTable attribute of TK_IF_NULL_ROW operators (that result from a prior flattening of a LEFT JOIN) are updated correctly. Fix for ticket [cad1ab4cb7b0fc344]. (check-in: 919d36e6 user: drh tags: branch-3.19)

2017-05-22
18:09
Fix incompatibilities between the "sqldiff --changeset" command and the sessions module.

(check-in: 0bb23c48 user: dan tags: trunk)
18:00

Include the "msvc.h" header file in the amalgamation tarball. (check-in: 3dd6fe53 user: drh tags: branch-3.19)
08:04
Fix a case where NULL was being passed to memcmp() following an OOM. This is probably not a real problem, as the number-of-bytes parameter was passed 0 in this case, but it was causing a santizer complaint. (check-in: 3ea2bad2 user: dan tags: trunk)
00:45
When planning a query using sorting, resolve ties in the solver by selecting loop plans with the smaller unsorted cost. (check-in: f261678c user: drh tags: trunk)

Add another test case for the new authorizer functionality. (check-in: 339df63f user: dan tags: trunk)
18:42
Enhance the json_extract() function to reuse parses of the same JSON when the function appears multiple times in the same query. (check-in: 3ba9e7ab user: drh tags: trunk)
18:14
Do not save the state of an fts5 merge operation mid-way through an input term, even if no previous entry for that term has caused any output. Doing so may corrupt the FTS index. (check-in: 9a2de4f0 user: dan tags: trunk)
16:49
Cache the JSON parse used by json_extract(). (Closed-Leaf check-in: 44ca6c2c user: drh tags: auxdata-cache)
15:20
Negative N values in sqlite3_get_auxdata() and sqlite3_set_auxdata() can be used to access an auxiliary data cache over all functions in a single prepared statement. (check-in: ff530675 user: drh tags: auxdata-cache)
13:43
New requirements marks and documentation for the authorizer. (check-in: 3980ea09 user: drh tags: trunk)

12:05
Change the SQLITE_READ authorization call for unreferenced tables to use an empty string for the column name, as this is less likely to impact legacy authorization callbacks that assume column names are always non-NULL. (check-in: 4139953a user: drh tags: trunk)
2017-05-10
19:42
Rename fields of the internal AuxData object to make them unique and easier to search for. (check-in: 2be9850c user: drh tags: trunk)
