9 check-ins using file src/window.c version df2bc081
|16:04||Enhancements and improved documentation to the byte-code branch coverage testing logic. Provide new macros that allow the code to specify that some branch instructions can never take the NULL path and that the OP_Jump opcode is only interested in equal/not-equal. The SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly differently (it provides the callback with a bitmask of the branch action, rather than an integer). check-in: cd2da7e1 user: drh tags: trunk|
|15:55||Experimental planner change to avoid a skip-scan if a regular index scan on the same index columns can be done instead. Leaf check-in: 350f29ea user: dan tags: exp-begin-concurrent-pnu|
|15:48||Merge begin-concurrent changes into this branch. check-in: af17432e user: dan tags: begin-concurrent-pnu|
|15:45||Merge latest trunk changes into this branch. check-in: e9a3e864 user: dan tags: begin-concurrent|
|07:39||Fix a harmless warning about comment formatting in the previous check-in. Simplify the ORDER BY dereferencing logic so that it avoids unreachable branches. check-in: 0f6ec605 user: drh tags: trunk|
|07:25||Assert that if two functions compare equal in every other way, then they must both have OVER clauses, or neither has an OVER clause. Use this fact to simplify expression comparison. check-in: 52559ad5 user: drh tags: trunk|
|06:47||Enhance the sqlite3ExprCompare() routine so that it knows to compare the OVER clause of window functions. check-in: 0a7649af user: drh tags: trunk|
|06:32||Enhance the TreeView mechanism so that it shows the window function data structures as part of the abstract syntax tree. check-in: a2c0e1be user: drh tags: trunk|
|05:11||New VDBE comments and coverage macros. check-in: a9a30726 user: drh tags: trunk|
