13:16 | Fix a typo in the header comment of the "series.c" virtual table extension. (check-in: d637feb4 user: drh tags: trunk) | |
2017-06-01
| ||
01:53 | Add a comment to the Lemon documentation regarding the security of the lemon.exe command-line tool. (check-in: 4c2458c1 user: drh tags: trunk) | |
00:54 | Add interfaces sqlite3_prepare_v3() and sqlite3_prepare16_v3() with the extra prepFlags argument. Add the SQLITE_PREPARE_PERSISTENT option as one bit in that argument. (check-in: 4a25c588 user: drh tags: prepare_v3) | |
2017-05-31
| ||
17:30 | Add the SQLITE_STMTSTATUS_MEMUSED opcode to sqlite3_stmt_status() for finding the heap memory usage by a single prepared statement. (check-in: c26cf978 user: drh tags: trunk) | |
16:21 | Add the SQLITE_STMTSTATUS_MEMUSED option for sqlite3_stmt_status() that reports the amount of heap memory used for a single prepared statement. (Closed-Leaf check-in: b57d5104 user: drh tags: stmtstatus-memused) | |
16:09 | Add the experimental "stmts" virtual table for introspection of prepared statements. (check-in: cb4c5c66 user: drh tags: trunk) | |
13:45 | Avoid allocating excess memory to the KeyInfo objects. (check-in: df785943 user: drh tags: trunk) | |
13:27 | Remove a completely unnecessary memset() from the INSERT code generator. (check-in: 7d58836b user: drh tags: trunk) | |
11:24 | Very small performance increase in sqlite3VdbeSetNumCols(). (check-in: 8885b446 user: drh tags: trunk) | |
03:20 | Reorder fields in the PgHdr object for a performance increase. (check-in: 326e63d7 user: drh tags: trunk) | |

00:49 | Size and performance optimizations to sqlite3ResolveExprNames(). (check-in: af8c0fed user: drh tags: trunk) | |
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) | |
2017-05-29
| ||
22:44 | More efficient error handling and reset in the binding mechanism. (check-in: 9a3e3b34 user: drh tags: trunk) | |
17:59 | Omit unnecessary fstat() calls for determining the database file size, resulting in smaller and faster code. (check-in: dd61c736 user: drh tags: trunk) | |
17:43 | Fix an issue with OPT_FEATURE_FLAGS in configure.ac. (check-in: 43ce3bd3 user: drh tags: trunk) | |

14:57 | Avoid unnecessary calls to fstat() to determine the database file size. (check-in: c733a1de user: drh tags: io-opt) | |
14:30 | Fix a typo in a comment. No code changes. (check-in: cb29b838 user: drh tags: trunk) | |
14:26 | Optimizations to the Walker object and its methods to make the code a little smaller and to help it run a little faster. (check-in: 6854a34e user: drh 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) | |
2017-05-27
| ||
22:42 | Smaller and faster vdbeSorterCompareText(). (check-in: 542dc4c5 user: drh tags: trunk) | |
2017-05-25
| ||
21:35 | Small performance increase and size decrease in the btreeInitPage() routine. (check-in: 6f415833 user: drh tags: trunk) | |
17:27 | Merge the LEFT JOIN query flattener fixes from 3.19.2. (check-in: 6513e4a1 user: drh tags: trunk) | |
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) | |
2017-05-24
| ||
15:32 | Fix harmless compiler warnings in FTS5. (check-in: 57a60e95 user: mistachkin tags: trunk) | |
04:18 | Fix a problem in STAT4 equality estimation for multi-column indexes introduced by check-in [3e0590dee0e68cc1599]. (check-in: cfb0d9e0 user: drh tags: trunk) | |
2017-05-23
| ||
20:00 | Remove the msvc.h header file from the autoconf tarball. (check-in: 84996aef user: drh tags: trunk) | |
19:35 | Do not use strcpy() in the (obsolete) amatch extension. In releasetest.tcl, run Apple tests using -Os instead of -O1 (check-in: 4440e420 user: drh tags: trunk) | |
15:21 | Disable the LEFT JOIN flattening optimization for aggregate queries, as it does not currently work. Further fix for ticket [cad1ab4cb7b0fc344]. (check-in: 44b21e35 user: drh tags: trunk) | |
12:36 | 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: 941d8142 user: drh tags: trunk) | |
01:21 | 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: 92c17850 user: drh tags: trunk) | |
00:32 | 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: 987a2b55 user: drh tags: trunk) | |
2017-05-22
| ||
18:09 | Fix incompatibilities between the "sqldiff --changeset" command and the sessions module. Specifically, allow sessions to process changesets containing tables with zero operations on them and have sqldiff output the expected output for tables with multi-column primary keys. (check-in: 0bb23c48 user: dan tags: trunk) | |
18:00 | Add the ".cd" command to the command-line shell. (check-in: 5fe28e15 user: drh tags: trunk) | |

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) | |
2017-05-19
| ||
22:51 | Prevent a possible NULL pointer dereference in the OP_Found opcode that can follow an OOM error. Problem found by OSS-Fuzz. (check-in: c2de178f user: drh tags: trunk) | |
20:55 | Improved comments on one routine in the query planner. Improved diagnostic output for ".wheretrace". No production code changes. (check-in: 946b87a5 user: drh tags: trunk) | |
20:47 | Fix a documentation typo. No changes to code. (check-in: 68942a4f user: drh tags: trunk) | |
