10 check-ins using file src/parse.y version 2eee45f4

2018-07-10
18:50
Modify tests in window3.test to be tolerant of rounding errors when comparing floating point values. (check-in: 7c26c443 user: dan tags: trunk)
17:26
Fix a problem with using scalar sub-selects in window function queries. (check-in: 687fe532 user: dan tags: trunk)
17:10
Further improvements to bytecode branch testing. Fix cases where the macros said a branch could not be taken when in fact it could be. Alter some window function branch coverage macros to indicate that comparison operands cannot be NULL. (check-in: 76e42b70 user: drh tags: trunk)
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)
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)
2018-07-09
22:49
Fixes for various harmless compiler warnings. (check-in: 5023b1b8 user: drh tags: trunk)
