If the seek must later be resolved, add the OP_FinishSeek opcode after all WHERE clause terms have been processed. This obviates the need for the WHERE_SEEK_TABLE and WHERE_SEEK_UNIQ_TABLE flags to sqlite3WhereBegin() and the ensuing complication, and it allows the covering index optimization to be used further into WHERE clause processing.

| 19:53 | [5a005fde92] part of check-in [1d44e5d3c2] Experimental change to the handling of foreign key constraint violations when applying a changeset: all foreign keys, immediate and deferred, are deferred until the end of the transaction (or sub-transaction) opened by the sqlite3changeset_apply(). A single call to the conflict-handler (if any) is made if any FK constraint violations are still present in the database at this point. The conflict-handler may choose to rollback the changeset or to apply it, constraint violations and all. (check-in: [1d44e5d3c2] user: dan branch: sessions, size: 144414) | |

2013-04-15
| ||
| 17:03 | [9933ad95b2] part of check-in [ea1404a10a] Refactoring the mmap interface. The controlling pragma is now "mmap_size" instead of "mmap_limit". Also change SQLITE_CONFIG_MMAP_LIMIT and SQLITE_FCNTL_MMAP_LIMIT to SQLITE_CONFIG_MMAP_SIZE and SQLITE_FCNTL_MMAP_SIZE, respecctively. The default mmap_size is now always 0, meaning that memory mapped I/O is off by default. There is a new compile-time option SQLITE_MAX_MMAP_SIZE that determines a hard upper bound on the mmap_size. Setting SQLITE_MAX_MMAP_SIZE to zero disables the memory-mapped I/O logic and causes it to be omitted from the build. An extra argument is added to SQLITE_CONFIG_MMAP_SIZE that can optionally lower the SQLITE_MAX_MMAP_SIZE at start-time. The SQLITE_MAX_MMAP_SIZE is zero for platforms where we know that it does not work, meaning that it cannot be turned on by mistake on those platforms.

| ||
| 20:53 | [0a39cbf63c] part of check-in [33cf83591e] Rework the logic that generates a schema for tables created using "CREATE TABLE ... AS SELECT ...". Instead of trying to copy the raw datatype string from the right-hand side, just make the type one of TEXT, INT, REAL, NUM, or nothing. This is much simpler than trying to parse and quote datatype strings. Other minor implifications to build.c are bundled with this change.

| ||
| 15:43 | [61be3597d7] part of check-in [5c737835de] Simplifications to the symbol table implementation in hash.c. For very small symbol tables (less than 10 entries) a simple linked list is used instead of a hash table. Number of hash table buckets is limited to prevent large allocations.

In addition to requiring less code, This removes the 2^32 result row limitation, uses less memory, and gives better bounds on worst-case performance. The Rowhash implementation has yet to be removed.

By clearly defining the upper bounds, we make those upper bounds explicitly testable. This check-in is just infrastructure. The upper bounds are not yet enforced.

| 03:54 | [6c25db3cdf] part of check-in [4062ddf3c7] Get the column affinities right when processing an IN operator where the right-hand side is a subquery with an ORDER BY clause. Ticket #2295. This bug has likely been present since version 3.0.0 and it has just now been noticed, so it seems to be a obscure case. (CVS 3837) (check-in: [4062ddf3c7] user: drh branch: trunk, size: 85575) | |

The changes in where.c and in the WhereLevel.aInLoop structure are not strictly necessary to fix this problem - they just make the code easier to read. Only the change in OP_Next/OP_Prev operator of vdbe.c is required. (CVS 3735) (check-in: [26348556d8] user: drh branch: trunk, size: 85362) | |

2007-02-28
| ||

|
2007-02-24

| 11:52 | [cc9f729ca2] part of check-in [e11bbf174c] Make sure that integer values are converted to real when pulled from a REAL table column by GROUP BY. Ticket #2251. Also make sure default values are correctly expanded. There may be other places in the code where this issue comes up - we need to look further. (CVS 3659) (check-in: [e11bbf174c] user: drh branch: trunk, size: 84603) | |

|
2007-02-13
| ||
| 12:49 | [409dfff7f0] part of check-in [22769e2d37] Expand the cursor index in SrcList_item to 32-bits to accomodate really huge VDBE programs resulting from deeply nested triggers. This is an interim fix until we rework triggers to use subroutines. (CVS 3640) (check-in: [22769e2d37] user: drh branch: trunk, size: 84499) | |
|
2007-02-01
| ||
| 23:02 | [650d05a8c5] part of check-in [85cca7cd25] First cut at adding the COLLATE operator. Regression tests pass (or at least the quick set does) and a few new tests have been added. But many more tests are needed. Rules for combining collations need to be worked out. (CVS 3624) (check-in: [85cca7cd25] user: drh branch: trunk, size: 84499) | |
| 01:40 | [f6053066ba] part of check-in [505dce8f4e] Allow up to 64 tables in a join (the number of bits in a long long int). The old limit was 32 tables. (CVS 3622) (check-in: [505dce8f4e] user: drh branch: trunk, size: 84365) | |

Ticket #2177. This check-in also adds the new test cases that were suppose to have been added with (3494) but which were mistakenly omitted. (CVS 3595) (check-in: [335863e4d1] user: drh branch: trunk, size: 84191) | |

Ticket #2023. (CVS 3541) (check-in: [a1bcc6de57] user: drh branch: trunk, size: 83887) | |
|
2006-12-16
| ||
| 16:25 | [28d060f44a] part of check-in [7393c81b8c] Query optimizer enhancement: In "FROM a,b,c left join d" allow the C table to be reordered with A and B. This used to be the case but the capability was removed by (3203) and (3052) in response to ticket #1652. This change restores the capability. (CVS 3529) (check-in: [7393c81b8c] user: drh branch: trunk, size: 83887) | |

| ||
| 07:28 | [74b39f55f3] part of check-in [ba579ddc43] Add support for extended result codes - additional result information carried in the higher bits of the integer return codes. This must be enabled using the sqlite3_extended_result_code() API. Only a few extra result codes are currently defined. (CVS 3422) (check-in: [ba579ddc43] user: drh branch: trunk, size: 83579) | |
