20:18
Add new sqlite3_prepare_v3() flag SQLITE_PREPARE_NO_VTAB, for preparing statements that are not allowed to use any virtual tables. Use this to prevent circular references in triggers on virtual table shadow tables from causing resource leaks. check-in: da587d18 user: dan tags: trunk

2018-11-06
19:26
Enable DEFENSIVE mode by default for tests. This requires lots of case of turning DEFENSIVE off in order to dodgy things to the database for testing purposes. No all of those cases are yet handled, so "make test" does not run to completion. check-in: a1d6c671 user: drh tags: read-only-shadow
14:03
Only allow shadow table to be written from within a recursive SQL call. Omit the SQLITE_PREPARE_SHADOW flag. Some tests are failing because the tests depend on being able to write to shadow tables. check-in: d890c658 user: drh tags: read-only-shadow
2018-11-05
23:01
Initial code to make shadow tables read-only to ordinary SQL. The now xShadowName method is added to the sqlite3_module object and is used to identify potential shadow tables. The SQLITE_PREPARE_SHADOW argument to sqlite3_prepare_v3() is defined. It is designed to permit writing to shadow tables, but is currently an unused placeholder. check-in: 31942b3d user: drh tags: read-only-shadow

18:55
Replace the new geopoly_reverse() function with geopoly_ccw(). The geopoly_ccw() function only reverses the vertex order if doing so is necessary to get the correct right-hand winding rule on the polygon. check-in: 07506694 user: drh tags: trunk
12:58
Add the geopoly_reverse() function to the GeoPoly extension. check-in: 690dd18a user: drh tags: trunk

Small performance optimization in the JSON parser of Geopoly. check-in: fb520e71 user: drh tags: trunk
