The PR addresses the issue #16040 . --- The logic used into the rule is the following: Suppose to have an expression of the form ```python if a cmp b: c = d ``` where `a`,` b`, `c` and `d` are Python obj and `cmp` one of `<`, `>`, `<=`, `>=`. Then: - `if a=c and b=d` - if `<=` fix with `a = max(b, a)` - if `>=` fix with `a = min(b, a)` - if `>` fix with `a = min(a, b)` - if `<` fix with `a = max(a, b)` - `if a=d and b=c` - if `<=` fix with `b = min(a, b)` - if `>=` fix with `b = max(a, b)` - if `>` fix with `b = max(b, a)` - if `<` fix with `b = min(b, a)` - do nothing, i.e., we cannot fix this case. --- In total we have 8 different and possible cases. ``` | Case | Expression | Fix | |-------|------------------|---------------| | 1 | if a >= b: a = b | a = min(b, a) | | 2 | if a <= b: a = b | a = max(b, a) | | 3 | if a <= b: b = a | b = min(a, b) | | 4 | if a >= b: b = a | b = max(a, b) | | 5 | if a > b: a = b | a = min(a, b) | | 6 | if a < b: a = b | a = max(a, b) | | 7 | if a < b: b = a | b = min(b, a) | | 8 | if a > b: b = a | b = max(b, a) | ``` I added them in the tests. Please double-check that I didn't make any mistakes. It's quite easy to mix up > and <. --------- Co-authored-by: Micha Reiser <micha@reiser.io> |
