18 check-ins related to "rtree-geopoly"

2018-08-27
17:13
Add support for the Geopoly extension to the R-Tree extension. This also involves adding the SQLITE_INDEX_CONSTRAINT_FUNCTION capability to the xFindFunction method of the sqlite3_module object, and to the sqlite3_index_info.aConstraint.op field in the xBestIndex implementation of virtual tables. (check-in: 666133e3 user: drh tags: trunk)
17:05
Minor changes to the visual01.txt test script. (Closed-Leaf check-in: 4bc28eed user: drh tags: rtree-geopoly)
15:55
Split the three-argument version of geopoly_within() off into a separate function named geopoly_contains_point(). (check-in: 5a0e1541 user: drh tags: rtree-geopoly)
2018-08-25
23:03
Enhance the geopoly virtual table so that it does a better job of optimizing geopoly_within() queries. (check-in: 1f717385 user: drh tags: rtree-geopoly)
19:51
Provide the two-argument geopoly_within(P1,P2) routine that determines if polygon P2 is contained within polygon P1. Make this function available to the query planner for optimized rtree lookups. Update the visual01.txt script to verify that the new functionality actually works. (check-in: 6eb5d09b user: drh tags: rtree-geopoly)
18:57
Fix a harmless compiler warning. (check-in: d49be983 user: drh tags: rtree-geopoly)
2018-08-23
14:54
Merge enhancements from trunk. (check-in: c446c884 user: drh tags: rtree-geopoly)
2018-08-17
21:14
Fix harmless compiler warnings only seen with STAT4 enabled. (check-in: 6f5e84ba user: mistachkin tags: trunk)
2018-05-29
17:17
Fix a problem in the geopoly json parser associated with spaces before a coordinate number. (check-in: 9d8d3af8 user: drh tags: rtree-geopoly)
2018-05-28
23:59
The geopoly virtual table seems to be working. But only thinly tested so far. (check-in: 4288f1ad user: drh tags: rtree-geopoly)
13:23
Untested incremental check-in. Add the geopoly_xform() function. Complete basic logic for the geopoly virtual table. (check-in: ed06cc32 user: drh tags: rtree-geopoly)
2018-05-26
20:04
Merge the ability to plan virtual table queries using overloaded functions. (check-in: 2c2a202c user: drh tags: rtree-geopoly)
18:03
Experimental change that allows overloaded functions to be analyzed by the xBestIndex method and used by the xFilter method of a virtual table. (Leaf check-in: a353b1d7 user: drh tags: vtab-func-constraint)
12:21
Minor correction. (check-in: f20d9a99 user: drh tags: rtree-geopoly)
2018-05-25
22:39
Untested incremental check-in. Basic infrastructure for geopoly in place, except for the MATCH operator. (check-in: b2745191 user: drh tags: rtree-geopoly)
20:53
Incremental check-in: Progress toward implementing the geopoly vtab. (check-in: 9b7d6f98 user: drh tags: rtree-geopoly)
19:22
Forward port the geopoly extension functions into the r-tree extension, with the idea of creating a new spatial index based on simply polygons. (check-in: 0593aac8 user: drh tags: rtree-geopoly)
2018-05-24
23:51
When doing a one-pass UPDATE or DELETE on virtual tables, close the cursor prior to running VUpdate. This allows one-pass to work on virtual tables that do not allow concurrent reads and writes. Enhance rtree to take advantage of this new capability. (check-in: b816023c user: drh tags: trunk)
