Add the sqlite3_rtree_query_callback() API to the RTree virtual table. check-in: 3dca280935 user: drh tags: sessions
2014-04-25
16:29
Enhance the sqlite3_rtree_query_info object to report on the number of elements in the priority queue at each level. Closed-Leaf check-in: f7dad408dd user: drh tags: rtree-enhancements
2014-04-21
18:13
Fix the generation of sqlite3_rtree_query_info.iRowid and add test cases to verify that it is fixed. check-in: eba95ead49 user: drh tags: rtree-enhancements
15:53
Be sure to initialize the sqlite3_rtree_query_info.iRowid field for the leaves of the R-Tree when doing a query callback search. check-in: 4394693882 user: drh tags: rtree-enhancements
15:21
Fix an off-by-one error in setting the "iLevel" field of the sqlite3_rtree_query_info structure passed into the RTree query callback. check-in: d708f159ab user: drh tags: rtree-enhancements

01:37
Further improvements to the RTREE_DECODE_COORD() method, to take advantage of known processor byte orders when available. This makes the code 3% faster, according to valgrind. Also add test cases to make sure the on-disk representation is correct. check-in: 6f3e94f4b1 user: drh tags: rtree-enhancements
01:14
Merge the latest changes from sessions. check-in: d9eef5b03c user: drh tags: rtree-enhancements
01:10
Merge recent trunk changes into sessions. check-in: 95e77efe07 user: drh tags: sessions

23:23
Performance optimization on byte-swapping in R-Tree. check-in: 444084fd62 user: drh tags: rtree-enhancements
15:34
More test cases with very long priority queues. check-in: 71692aa97c user: drh tags: rtree-enhancements
14:52
Test cases and bug fixes for the sqlite3_rtree_query_callback() mechanism. check-in: 1ccaaed6b5 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: 32a1387017 user: drh tags: rtree-enhancements
2014-04-16
21:02
Performance optimization on nodeGetCell() in R-Tree. check-in: 5d20ff9ec8 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: f26936f71a user: drh tags: rtree-enhancements
17:15
TCL tests now all pass. Closed-Leaf check-in: f864baccd3 user: drh tags: rtree-queue
2014-04-15
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: 53688a25c2 user: drh tags: rtree-queue
2014-04-14
14:43
Fix comments on the rtreenode() and rtreedepth() test function in the R-Tree module. check-in: ade5b986e8 user: drh tags: rtree-enhancements
12:18
Remove over 300 lines of unused code, code that implemented the older Guttman insertion algorithms that are no longer used. check-in: 3ba5f295c7 user: drh tags: rtree-enhancements
2014-04-13
16:10
Continuing work on the new custom query mechanism for r-tree. check-in: ca7357e66c user: drh tags: rtree-enhancements
2014-04-12
17:44
Continuing clean-up of the R-Tree module in preparation for cutting in the new generalized query mechanism. check-in: 66c858f205 user: drh tags: rtree-enhancements
2014-04-11
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: 0b70275972 user: drh tags: rtree-enhancements
17:41
Add the --verify option to speedtest1. Add verification test cases to the "rtree" testset and a case that uses a custom geometry callback. check-in: 9d485c4207 user: drh tags: rtree-enhancements
16:14
Update comments in the R-Tree module in preparation for some big changes. Add an "rtree" performance test to speedtest1. check-in: 20a73ec0b2 user: drh tags: rtree-enhancements
2014-04-03
16:35
Merge all recent changes from trunk, including the fix for the OP_SCopy-vs-OP_Copy problem. check-in: 9515c8344a user: drh tags: sessions
