New submission from Lysandros Nikolaou <[email protected]>:
There is a problem with the end_col_offset of nested Attribute nodes in
decorators. For example, parsing
@a.b.c
def f(): pass
produces the following AST tree (part):
decorator_list=[
Attribute(
value=Attribute(
value=Name(
id="a",
ctx=Load(),
lineno=1,
col_offset=1,
end_lineno=1,
end_col_offset=2,
),
attr="b",
ctx=Load(),
lineno=1,
col_offset=1,
end_lineno=1,
*end_col_offset=6*,
),
attr="c",
ctx=Load(),
lineno=1,
col_offset=1,
end_lineno=1,
end_col_offset=6,
)
],
Note that the Attribute node with attr="b" has end_col_offset=6, while it
should actually be 4.
