47c8f3756b Merge pull request #1580 from seeeturtle/doc-f 
Set docstring of function as None if not declared
 2019-11-02 19:18:11 +02:00
joshua1b
30ab196fdc Set docstring of function as None if not declared 
In cpython, if there is no docstring declared in function definition,
the `__doc__` attribute of the function is None.
So this implements the behavior.

Fix #1523

142a29be4a Fix wrong const optimization for "1.0 / 0.0" case 
In cpython, "1.0 / 0.0" raises ZeroDivisionError
```
>>> 1.0 / 0.0
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ZeroDivisionError: float division by zer
```

but RustPython doesn't
```
>>>>> 1.0 / 0.0
inf
```

This is because they emits different byte codes.

```
$ echo "1.0 / 0.0" > zero-div.py

$ python -m dis zero-div.py
  1           0 LOAD_CONST               0 (1.0)
              2 LOAD_CONST               1 (0.0)
              4 BINARY_TRUE_DIVIDE
              6 POP_TOP
              8 LOAD_CONST               2 (None)
             10 RETURN_VALUE

$ cargo run --example dis zero-div.py
zero-div.py:
                 0 LoadConst            (inf)
                 1 Pop
                 2 LoadConst            (None)
                 3 ReturnValue
```

This commit stops optimization for zero division case
to generate same byte codes.
