| ||
| 01:23 | Add the OP_SorterColumns opcode - an experiment in using a special case opcode to decode the Sorter output rather than the generic OP_Column. This might be faster. And with further work, it could eventually eliminate the need for OP_OpenPseudo. (check-in: b9c695e885 user: drh tags: OP_SorterColumns) | |
|

| ||
| 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.

| 23:31 | Performance optimization and very slight size reduction for OP_Column. (check-in: 869c30e45c user: drh tags: trunk) | |
| 20:00 | Attempt to further reduce memcpy() in balance_nonroot(). (check-in: fec849dcca user: dan tags: defrag-opt) | |
| 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: 66de15580d 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: 5d29a033b0 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: 7a32fdfd4b user: drh tags: trunk) | |
| 01:22 | Remove an unnecessary conditional from the EXPLAIN QUERY PLAN logic. (check-in: c5dc83ebde 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: 2a9573962b user: dan tags: experimental) | |
| 19:15 | Restrict the scope of the explainIndexRange() function in where.c. (check-in: c301245200 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: 8541dfb3bb user: dan tags: trunk) | |
| 18:09 | Changes to enable compiling using VC6. (check-in: 9ee5686ab3 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: cf291cbe9f 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: d479e32be2 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: daa8314fba user: drh tags: trunk) | |
| 15:47 | Simplify the code used to generate the text for EXPLAIN QUERY PLAN. (check-in: beea1efc3a 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: 68e1b4de70 user: drh tags: trunk) | |
| 13:08 | Cause the command-line shell to return non-zero if the final SQL statement is incomplete. (check-in: 177fff3b98 user: drh tags: trunk) | |
| 12:56 | Merge all recent trunk changes. (check-in: abfef25472 user: drh tags: sessions) | |
|
2014-10-09
| ||
| 19:35 | Change the balance_nonroot() routine to reduce the amount of memcpy work that takes place. This is a work in progress. (check-in: 29304499ea user: dan tags: defrag-opt) | |
| 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: 49dfee7cd1 user: dan tags: trunk) | |
| 14:10 | Add a test case for the memory leak fixed by the previous check-in. (check-in: bae36d5446 user: drh tags: trunk) | |
| 14:00 | Fix a memory leak associated with the FTS4 matchinfo() function. (check-in: fb8da82411 user: drh tags: trunk) | |
| 11:40 | Record the errno on fstat() failures. (check-in: 2a6a082001 user: drh tags: apple-osx) | |
| 11:27 | Merge the latest trunk enhancements into the apple-osx branch. (check-in: 6fc7207727 user: drh tags: apple-osx) | |
|
2014-10-08
| ||
| 19:33 | Remove an always-true branch in whereRangeScanEst(). Replace it with an assert(). (check-in: 42e48fd3a6 user: drh tags: trunk) | |
| 15:53 | Fix up test cases to account for the new SQLITE_LIMIT_WORKER_THREADS limit. (check-in: 6483d426c4 user: drh tags: trunk) | |
| 14:28 | Set the connection-specific lastRowid value before calling any SQL function. (check-in: dff0f6422e 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: e4b43967fd user: drh tags: trunk) | |
| 11:11 | Remove some temporary code in mallocA.test that was accidentally checked in. (check-in: dedd15f7cd user: dan tags: trunk) | |
| 02:53 | Fix the STAT4 range scan estimates for DESC indexes. (check-in: e3fe840052 user: drh tags: trunk) | |
| 00:08 | More intuitive labels on ".wheretrace" output. (check-in: adcb3fed48 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: f672a380e2 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: e405b9e4a9 user: drh tags: trunk) | |
| 16:59 | Restrict the scope of the valueToText() routine. (check-in: 13c962b33d user: drh tags: trunk) | |
| 15:46 | Enhance (and fix) the MEMTYPE tags associated with heap memory allocations when SQLITE_MEMDEBUG is used. (check-in: ca5b789e33 user: drh tags: trunk) | |
|
2014-10-06
| ||
| 18:33 | Remove unreachable branches in decodeIntArray() when compiling without STAT3 or STAT4. (check-in: 80e1baa5c2 user: drh tags: trunk) | |
| 14:37 | Improve the accuracy of the estimates used when searching an index for values not present in any stat4 samples. (check-in: 3aff9a9cac user: dan tags: trunk) | |
| 12:41 | Fix a harmless compiler warning inside an assert() in FTS4. (check-in: 418f3c9ad2 user: drh tags: trunk) | |
|
2014-10-04
| ||
| 19:31 | Tweaks to documentation on sqlite3_open() and sqlite3_bind(). No code changes. (check-in: b8f7f19dc0 user: drh tags: trunk) | |
| 11:59 | Updates to documentation and requirements marks. No code changes. (check-in: 0f8102d71a user: drh tags: trunk) | |
| 10:22 | Add a test to show that the change on this branch is effective. (Closed-Leaf check-in: fc619be057 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: efd87ba142 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: f9c053b23e 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: e6f7f97dbc 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: d2fc322728 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: 440705b98a 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: ffe7573636 user: drh tags: trunk) | |
| 09:27 | Fix a segfault that could occur if an 'optimize' command was issued on an FTS table that contained at least one row but zero terms. (Leaf check-in: b21746ac11 user: dan tags: branch-3.7.14) | |
|
2014-10-01
| ||
| 13:17 | Show the TK_DOT operator in the TreeView debugging output. No changes to production code. (check-in: 07c89940c4 user: drh tags: trunk) | |
