21:17
More fixes for different window frame types. Leaf check-in: 2c85668a user: dan tags: exp-window-functions

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
16:00
Store application-defined function names as lower-case to avoid the need for case conversions before calling xFindFunction on virtual tables. Avoid using lookaside to store the destructors for application defined functions, as lookaside should be reserved for transient allocations. Leaf check-in: 777189ce user: drh tags: trunk
13:55

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
