|
2014-08-26
| ||

| 20:11 | Allow CAST expressions and unary "+" operators to be used in the DEFAULT argument of an ALTER TABLE ADD COLUMN and to be understand on the RHS of range constraints interpreted by STAT3/4. This involves a rewrite of the implementation of the CAST operator. (check-in: 91d8a8d0 user: drh tags: trunk) | |
| 19:58 | Add documentation for tokenizer api to fts5.h. Also add a script to extract extension API docs and format them as html. (check-in: e240d467 user: dan tags: fts5) | |

| 11:33 | Remove the pager_lookup() function since it is redundant with sqlite3PagerLookup(). (check-in: 54164ce4 user: drh tags: trunk) | |
| 11:20 | Change the name of the VdbeMemRelease() macro to VdbeMemReleaseExtern() to more accurately reflect what it does. Performance enhancement to the sqlite3VdbeMemRelease() function. (check-in: 3ca5846d user: drh tags: trunk) | |
|
2014-08-24
| ||
| 02:53 | The sqlite3VdbeChangeEncoding() routine goes about 3x faster if the sqlite3VdbeMemTranslate() subroutine is not inlined. (check-in: 0c7e1b87 user: drh tags: trunk) | |

|
2014-08-22
| ||
| 23:33 | Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine into two with the second routine named sqlite3BtreeCursorRestore(). The first now only reports whether or not the cursor has moved and the second tries to restore the cursor. This allows the sqlite3VdbeCursorMoveto() routine to be refactored to avoid stack pointer movements, for a noticable performance gain. (check-in: ce123b5c user: drh tags: trunk) | |

| 16:09 | Merge all recent trunk changes, especially the fix for ticket [369d57fb8e5ccdff06f1], but also the skip-scan improvement and performance improvements in the b-tree code. (check-in: 0b9e2c32 user: drh tags: sessions) | |
| 14:10 | Fix a faulty assert() statement. Add comments to clarify the behavior of the sqlite3OpenTableAndIndices() routine in insert.c. Add test cases to verify that the assert() statement is not firing inappropriately. Ticket [369d57fb8e5ccdff06f1]. (check-in: 7029b340 user: drh tags: trunk) | |

| 14:52 | Test cases and bug fixes for the sqlite3_rtree_query_callback() mechanism. (check-in: 1ccaaed6 user: drh tags: rtree-enhancements) | |
| 13:15 | Refactor the constraint checking logic in RTree. The new-style constraint callbacks created by sqlite3_rtree_query_callback() are now hooked up from end to end, though still untested. (check-in: 32a13870 user: drh tags: rtree-enhancements) | |

| 17:23 | Convert the RTree module query mechanism over to using a priority queue for walking the RTree. (check-in: f26936f7 user: drh tags: rtree-enhancements) | |
| 17:15 | TCL tests now all pass. (Closed-Leaf check-in: f864bacc user: drh tags: rtree-queue) | |
| 14:45 | Fix a bug in rowid=? query handling. More problems remain. (check-in: 5b0e6ba4 user: drh tags: rtree-queue) | |
| 13:00 | Bug fixes to the priority-queue implementation for R-Trees. Improved tracing capability. Some queries work now, but still many problems. (check-in: a439ddd6 user: drh tags: rtree-queue) | |

| 21:06 | Initial attempt at getting R-Tree queries to work using a priority queue. This check-in compiles, but R-Trees do not work well. And there are debugging printf()s left in the code. This is an incremental check-in. (check-in: 53688a25 user: drh tags: rtree-queue) | |

| 23:14 | Add the new interfaces to rtree, though they do not yet work. Add the "show_speedtest1_rtree.tcl" script for showing the test data used for the R-Tree tests of speedtest1. Change speedtest1 to generate better R-Tree test data. (check-in: 0b702759 user: drh tags: rtree-enhancements) | |
