18 check-ins using file src/vdbeaux.c version f9c225c2

2014-04-17
23:23
Performance optimization on byte-swapping in R-Tree. (check-in: 444084fd user: drh tags: rtree-enhancements)
15:34
More test cases with very long priority queues. (check-in: 71692aa9 user: drh tags: rtree-enhancements)
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)
2014-04-16
21:02
Performance optimization on nodeGetCell() in R-Tree. (check-in: 5d20ff9e 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)
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: 53688a25 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: ade5b986 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: 3ba5f295 user: drh tags: rtree-enhancements)
2014-04-13
16:10
Continuing work on the new custom query mechanism for r-tree. (check-in: ca7357e6 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: 66c858f2 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: 0b702759 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: 9d485c42 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: 20a73ec0 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: 9515c834 user: drh tags: sessions)
