11:31
Rearrange an expression in vdbemem.c to avoid a (harmless) reference to a possibly unitialized variable. check-in: 4a7b3fa0 user: dan tags: trunk
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. check-in: 66de1558 user: drh tags: trunk
10:52
Require the SQLITE_ENABLE_RTREE compile-time option in speedtest1.c in order to enable the R-Tree tests. check-in: 5d29a033 user: drh tags: trunk
02:12
Make sure that a GROUP BY that also implements an ORDER BY scans the table in the correct order. Fix for ticket [ba7cbfaedc7e6]. check-in: 7a32fdfd user: drh tags: trunk
01:22
Remove an unnecessary conditional from the EXPLAIN QUERY PLAN logic. check-in: c5dc83eb user: drh tags: trunk
2014-10-10
20:52
Account for the ASC/DESC properties of ORDER BY expressions when using the same index for GROUP BY and ORDER BY. Candidate fix for [ba7cbfaedc]. Closed-Leaf check-in: 2a957396 user: dan tags: experimental
19:15
Restrict the scope of the explainIndexRange() function in where.c. check-in: c3012452 user: drh tags: trunk
19:10
Fix a failing test case in index5.test. Also tweak the way cache memory is divided between read-only and dirty pages when using SQLITE_CONFIG_PAGECACHE to reduce IO in some cases. check-in: 8541dfb3 user: dan tags: trunk
18:09
Changes to enable compiling using VC6. check-in: 9ee5686a user: drh tags: trunk
17:47
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
15:47
Simplify the code used to generate the text for EXPLAIN QUERY PLAN. check-in: beea1efc user: drh tags: trunk
15:01
Fix a potential problem in the whereRangeScanEst() routine when STAT4 is active. The problem was introduced by recent enhancements. check-in: 68e1b4de user: drh tags: trunk
13:08
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
14:10
Add a test case for the memory leak fixed by the previous check-in. check-in: bae36d54 user: drh tags: trunk
14:00
Fix a memory leak associated with the FTS4 matchinfo() function. check-in: fb8da824 user: drh tags: trunk
2014-10-08
19:33
Remove an always-true branch in whereRangeScanEst(). Replace it with an assert(). check-in: 42e48fd3 user: drh tags: trunk
15:53
Fix up test cases to account for the new SQLITE_LIMIT_WORKER_THREADS limit. check-in: 6483d426 user: drh tags: trunk
14:28
Set the connection-specific lastRowid value before calling any SQL function. check-in: dff0f642 user: drh tags: trunk
13:34
Ensure that the Pager.pTmpSpace allocation is correct even if an OOM error occurs while reducing the page size. check-in: e4b43967 user: drh tags: trunk
11:11
Remove some temporary code in mallocA.test that was accidentally checked in. check-in: dedd15f7 user: dan tags: trunk
02:53
Fix the STAT4 range scan estimates for DESC indexes. check-in: e3fe8400 user: drh tags: trunk
00:08
More intuitive labels on ".wheretrace" output. check-in: adcb3fed user: drh 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
16:59
Restrict the scope of the valueToText() routine. check-in: 13c962b3 user: drh tags: trunk

2014-10-04
19:31
Tweaks to documentation on sqlite3_open() and sqlite3_bind(). No code changes. check-in: b8f7f19d user: drh tags: trunk
11:59
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
19:16
Improve the accuracy of the estimates used when searching an index for values not present in any stat4 samples under some circumstances. check-in: e6f7f97d 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
13:17
Show the TK_DOT operator in the TreeView debugging output. No changes to production code. check-in: 07c89940 user: drh tags: trunk
12:01
Avoid ever writing before the start of an allocated buffer in the DIRECT_OVERFLOW_READ code. Fix for [e3a290961a6]. check-in: c3c15d20 user: dan tags: trunk
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
02:44
Change that might allow SQLite to build and work using the EBCDIC character set. check-in: ef30e035 user: drh tags: trunk
00:56
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
