2014-10-14
20:25
Make sure new sqlite3_vtab objects created by the xCreate() virtual table method are initialized by the system, in accordance with the documentation. (check-in: eab82330 user: drh tags: trunk)
2014-10-13
23:39
Optimize a database corruption test inside of the OP_Column opcode. (check-in: 005e5b38 user: drh tags: trunk)
20:12
Use the padding word in the Mem object as temporary storage for serial_type value in OP_Record, and thus avoid a redundant computation of the serial_type for each column. (check-in: 4b3b65ee user: drh tags: trunk)
17:42
Three small optimizations to vdbeaux.c. (check-in: 04892f8b user: drh tags: trunk)
16:02
Reduce the CPU load imposed by sqlit3VdbeCursorMoveto() by factoring out some of its functions and by avoiding unnecessary calls. (check-in: c2799aec user: drh tags: trunk)
13:00
Remove the OPFLAG_CLEARCACHE flag from OP_Column. In its place, change the P3 parameter of OP_SorterData to be the index of the pseudo-table cursor whose record header cache is to be cleared. This gives a small size reduction and performance increase. (check-in: 20062f49 user: drh tags: trunk)
2014-10-12
22:37
Remove the VdbeCursor.lastRowid cache of the current rowid, since maintaining the correct cache value uses more CPU cycles than just recomputing the rowid on the occasions when it is actually needed. Replace it with the VdbeCursor.aOffset field which used to be computed from VdbeCursor.aType when needed. Saves 100 bytes of code space and runs 0.2% faster. (check-in: 91384a7d user: drh tags: trunk)
2014-10-11
23:31
Performance optimization and very slight size reduction for OP_Column. (check-in: 869c30e4 user: drh tags: trunk)
17:22
Simplification to the insertCell() routine in btree.c, resulting in a performance boost and a very small size decrease. It turns out that the extra work involved in sometimes avoiding an memcpy() of the first four bytes of a record takes more time than just unconditionally copying those four bytes.

When using the -config option to releasetest.tcl, default the testing type to "fulltest" if it is not specified on the command line. (check-in: cf291cbe user: drh tags: trunk)
17:44
Provide the new "-config CONFIG" option to the test/releasetest.tcl script, which allows one to run a single test configuration selected by name. (check-in: d479e32b user: drh tags: trunk)
17:20
Add the estimated number of output rows to the EXPLAIN QUERY PLAN output if compiled with SQLITE_EXPLAIN_ESTIMATED_ROWS. This feature is off by default for the time being. (check-in: daa8314f user: drh tags: trunk)

Cause the command-line shell to return non-zero if the final SQL statement is incomplete. (check-in: 177fff3b user: drh tags: trunk)
2014-10-09
15:08
Allow FTS tokenizers to choose whether or not to consider the "*" character part of tokens or not. This restores the pre-[e21bf7a2ad] behaviour. Also fix a problem causing FTS to interpret tokens beginning with "*" characters as EOF. (check-in: 49dfee7c user: dan tags: trunk)

2014-10-07
23:02
Make sure the sqlite3VdbeMemClearAndResize() routine is never called with a zero size parameter, since a size of zero could lead to either a memory leak or an assertion fault. (check-in: f672a380 user: drh tags: trunk)
20:09
Fix the corruptI.test script so that it works with SQLITE_ENABLE_OVERSIZE_CELL_CHECK and with SQLITE_DEFAULT_AUTOVACUUM=1. (check-in: e405b9e4 user: drh tags: trunk)

Updates to documentation and requirements marks. No code changes. (check-in: 0f8102d7 user: drh tags: trunk)
10:22
Add a test to show that the change on this branch is effective. (Closed-Leaf check-in: fc619be0 user: dan tags: stat4-avgeq)
00:07
Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine has a chance to run. Since the aiRowEst now might be deleted from freeIndex() which does not always have a db pointer, make sure the aiRowEst memory is not held in lookaside. (check-in: efd87ba1 user: drh tags: stat4-avgeq)
2014-10-03
19:29
Fix a division-by-zero error that might occur if the sqlite_stat1 table is corrupt. (check-in: f9c053b2 user: dan tags: stat4-avgeq)

16:00
Add requirements marks on the sqlite3_db_status() interface implementation. Fix a typo in the documentation. Fix the new sqlite3_result_text64() routine so that it works correctly with an encoding parameter of SQLITE_UTF16. (check-in: d2fc3227 user: drh tags: trunk)
14:54
Update to requirements marks related to changes in the memory allocation interface and enhancement of the documentation regarding DEFAULT clauses in CREATE TABLE. (check-in: 440705b9 user: drh tags: trunk)
2014-10-02
21:52
Avoid a NULL pointer deference when processing the IS operator if the right-hand side is an illegal "#ID" style variable. Fix for ticket [8c32a33a53092c85a15b] (check-in: ffe75736 user: drh tags: trunk)
2014-10-01

2014-09-30
19:04
Improvements to the new syntax-tree output routines: Omit the "END SELECT" mark and instead terminate the graph at the last item. Increase the maximum tree depth to 100. (check-in: 5ce05757 user: drh tags: trunk)
17:31
Enable the query planner to deal with WHERE clauses that have OR terms nested within AND terms that are nested within OR terms. Also remove an unused function declaration. (check-in: b6b28918 user: drh tags: trunk)
17:03
Further enhancements to the "wheretrace" debugging output. (check-in: 670993eb user: drh tags: trunk)
14:14
Enhanced debug output for OR-logic in the query loop optimizer. (check-in: 2e375eae user: drh tags: trunk)
13:46
Show tree diagrams of data structures in the debugging output when the 0x100 bit is set on sqlite3WhereTrace or sqlite3SelectTrace. (check-in: 92e0b4bd user: drh tags: trunk)
12:33
Remove the SQLITE_ENABLE_TREE_EXPLAIN compile-time option. Add alternative debugging display routines: sqlite3TreeViewExpr(), sqlite3TreeViewExprList(), and sqlite3TreeViewSelect(). (check-in: 4ff51325 user: drh tags: trunk)
2014-09-29
15:42
Fix the header comment in sqlite3VdbeDeletePriorOpcode(). No changes to code. (check-in: 7fb16268 user: drh tags: trunk)
15:00
Ensure that the OP_Prev opcode verifies that content has not been deleted out from under the cursor. Fix for ticket [209d31e3161b9e9ff]. (check-in: 414f0d6a user: drh tags: trunk)
2014-09-26
18:30
Add an assert() to verify the last-row-id for the database just prior to calling a SQL function. (check-in: d026f0c9 user: mistachkin tags: trunk)
02:41
Fix the "PRAGMA integrity_check" command so that it avoids formatting error message context messages until it actually needs to generate an error message. This avoids much formatting, and hence greatly improves the performance of "PRAGMA integrity_check" in the common case when there are no errors. It also makes the code a little smaller. (check-in: 83913515 user: drh tags: trunk)
01:10
If an SQL function makes a recursive call to do an INSERT into the same database, make sure that the last_insert_rowid() for that INSERT is recorded. (check-in: e93aecc0 user: drh tags: trunk)
2014-09-25
17:42
Minor code reformatting and comment change, to improve clarity. No logic changes. (check-in: baeb72a3 user: drh tags: trunk)
13:17
Simplifications to the SQL function and aggregate calling procedures. (check-in: 3467049a user: drh tags: trunk)
12:31
Simplification to the random rowid picking logic that begins running when the maximum possible rowid has already been used. (check-in: 1330c72e user: drh tags: trunk)
11:08
Still more performance enhancements to the LIKE and GLOB operators. (check-in: 6c8924ca user: drh tags: trunk)
03:51
More performance optimization for the LIKE and GLOB operators. (check-in: 5ab1023d user: drh tags: trunk)

Size reduction and performance improvement in the LIKE and GLOB operators. (check-in: b2c89ef4 user: drh tags: trunk)
2014-09-24
19:47
Have each open database allocate its pTmpSpace when the first write cursor is opened, rather than on each insert or delete, for a small space savings and performance boost. (check-in: 99323552 user: drh tags: trunk)
18:31
Small performance and size optimization for btreeUnlockIfUnused(). (check-in: 13c746f8 user: drh tags: trunk)
13:20
Do not allow parameters in a DEFAULT clause of a CREATE TABLE statement. Ticket [78c0c8c3c9f7c1]. (check-in: 1ad2bc1e user: drh tags: trunk)
02:05
Have the clearCell() routine return the cell size to the caller, rather than have the caller make a separate call to cellSizePtr(). (check-in: f21d2175 user: drh tags: trunk)
01:23
Shorten all lines of source code in btree.c to at most 80 characters. No logical changes. (check-in: 5dd41cdb user: drh tags: trunk)
00:59
Add the MemPage.noPayload boolean and use it to help cellSizePtr() and btreeParseCellPtr() run faster. (check-in: 8e337531 user: drh tags: trunk)
2014-09-23
23:12
Remove an unused C-preprocessor macro. No functional changes to the code. (check-in: f480582c user: drh tags: trunk)
22:36
Avoid calling btreeParseCellPtr() from within fillInCell() since most of what btreeParseCellPtr() computes is ignored by fillInCell(). Instead, have fillInCell() compute the values it needs inline. Performance improvement. (check-in: 4147f667 user: drh tags: trunk)
21:25
Simplify the CellInfo structure for a size reduction and performance improvement. (check-in: bf59df66 user: drh tags: trunk)
18:30
Add the "multiplex_truncate" PRAGMA to the multiplexor extension, for querying and setting the truncate flag on a database connection. (check-in: d2962a5f user: drh tags: trunk)
