31 check-ins using file src/sqlite.h.in version 125dc0b7

2015-08-13
| ||
| 21:43 | Convert the hint expression of the CursorHint opcode into a string for display by EXPLAIN. (Leaf check-in: 12640cb2 user: drh tags: cursor-hints-displayP4) | |
|
2014-07-15
| ||
| 11:59 | Add simple tests for new sqlite3BtreeCursorHint() functionality. (check-in: 1efa6ed5 user: dan tags: cursor-hints) | |
|
2014-07-14
| ||
| 19:04 | In the expression passed to sqlite3BtreeCursorHint() for the inner loops of joins, replace any TK_COLUMN references to columns in the outer loops with TK_REGISTER expressions (Expr.iTable indicates the specific register containing the value). There are no automated tests for this yet. (check-in: f9dddd00 user: dan tags: cursor-hints) | |
|
2013-12-11
| ||
| 14:00 | Fix a bug in the shell ".import" command: Do not end the field when an escaped double-quote occurs at the end of a CRNL line. (check-in: 5e239ecd user: drh tags: trunk) | |
| 12:02 | Remove an unreachable conditional inserted by the previous check-in. (check-in: 3e1d55f0 user: drh tags: trunk) | |
| 11:00 | Fix harmless compiler warnings. (check-in: a7e5fcd6 user: drh tags: trunk) | |
| 02:21 | Fix harmless compiler warning. (check-in: 2525296d user: mistachkin tags: trunk) | |
| 00:59 | Do not run the tool/vdbe-compress.tcl script that generates the vdbeExecUnion object that reduces the size of the sqlite3VdbeExec() stack frame unless the SQLITE_SMALL_STACK compile-time option is specified as on of the OPTS in the makefile. The vdbeExecUnion object gets in the way of C-compiler optimizer and results in slightly slower code. (check-in: 4d078147 user: drh tags: trunk) | |
|
2013-12-10
| ||
| 21:38 | Avoid unnecessary calls to sqlite3VdbeSerialType() from within sqlite3VdbeSerialPut(). (check-in: 079c04a5 user: drh tags: trunk) | |
| 20:53 | In the OP_MakeRecord opcode, factor out affinity changes into separate loop, for a slight performance advantage. (check-in: 1c6ee9b8 user: drh tags: trunk) | |
| 19:49 | Simplify and improve the performance of the sqlite3VdbeMemGrow() routine. (check-in: 48ecf187 user: drh tags: trunk) | |
|
2013-12-09
| ||
| 23:17 | Simplifications to the OP_MakeRecord opcode and the sqlite3VdbeSerialPut() helper function. (check-in: 7277a769 user: drh tags: trunk) | |
| 21:48 | Correct the VFS name as reported by the file control when explicitly using the 'win32-longpath' VFS. (check-in: c43b59da user: mistachkin tags: trunk) | |
| 21:06 | Reduce the number of times that OP_Column calls sqlite3VdbeMemMakeWriteable(). (check-in: 6b518635 user: drh tags: trunk) | |
| 20:43 | Simplify the sqlite3BtreeKeyFetch() and sqlite3BtreeDataFetch() interfaces to the storage engine. (check-in: bf975985 user: drh tags: trunk) | |
| 19:25 | Minor performance optimizations in pager.c. (check-in: ba9eef5f user: drh tags: trunk) | |
| 19:03 | Performance optimizations for sqlite3VXPrintf(). (check-in: 9227ad48 user: drh tags: trunk) | |
| 12:24 | Fix an incorrect test number in the output of the speedtest1.c program. No changes to the test algorithms. (check-in: fbfc075a user: drh tags: trunk) | |
| 03:07 | Avoid unnecessary (no-op) calls to sqlite3DbFree() from sqlite3VdbeMemRelease(). (check-in: 2d6dd7c2 user: drh tags: trunk) | |
| 02:32 | Use memmove() rather than a home-made copy loop in insertCell() too. (check-in: a3d796b1 user: drh tags: trunk) | |
| 01:58 | Use memmove() rather than a home-made copy loop in dropCell() of btree.c, for a size reduction and performance improvement. (check-in: 78e17068 user: drh tags: trunk) | |
| 01:04 | Avoid unnecessary no-op calls from getAndInitPage() to btreeInitPage() in the btree.c logic. (check-in: 81f5ae13 user: drh tags: trunk) | |
| 00:47 | Use putVarint32() instead of putVarint() for a quantity that can never exceed 2GiB - 1. (check-in: 6996fb34 user: drh tags: trunk) | |
|
2013-12-08
| ||
| 23:33 | Another simplification to the OP_MakeRecord opcode, making it slightly faster and very slightly smaller. (check-in: f2f5a3ce user: drh tags: trunk) | |
| 22:59 | Avoid unnecessary calls to sqlite3VarintLen() from the OP_MakeRecord opcode. (check-in: 7a234fc3 user: drh tags: trunk) | |
| 19:54 | Interchange two conditions in an "if" statment in sqlite3PagerAcquire() for very slight (0.06%) overall performance increase. (check-in: fbcc1a3e user: drh tags: trunk) | |
|

| 23:35 | Do not allow cursor hints to use expressions containing subqueries. This change fixes the problem seen in the previous check-in. (check-in: bfefc575 user: drh tags: cursor-hints) | |
| 20:39 | If the SQLITE_ENABLE_CURSOR_HINTS macro is defined, then invoke the sqlite3BtreeCursorHint() interface to provide hints to the storage engine about rows that need not be returned. Hints can be disabled using SQLITE_TESTCTRL_OPTIMIZATIONS with SQLITE_CursorHints (0x2000). Cursor hints are not used by the built-in storage engine of SQLite but might be useful to applications that provide their own storage engine. The current code is work-in-progrss and contains bugs. (check-in: 3a9bec52 user: drh tags: cursor-hints) | |
| 17:01 | Increase the version number to 3.8.3. (check-in: 23d00f22 user: drh tags: trunk) | |
| 16:56 | At the start of each journaled write transaction, check to see if the database file has been moved, and if it has refuse to start the transaction, returning an SQLITE_READONLY_DBMOVED error code. Writing to a moved or renamed database is still allowed when journal_mode is OFF or MEMORY. (check-in: 369a23e0 user: drh tags: trunk) | |
| 16:45 | Back out the new device capability. The determination of whether or not a file has moved is now done strictly using a file-control. (Closed-Leaf check-in: 9c59f5af user: drh tags: detect-moved-db) | |
