The __hash__() methods of ipaddress.IPv4Interface and
|
|
ipaddress.IPv6Interface incorrectly generated constant hash values of 32 and
|
|
128 respectively. This resulted in always causing hash collisions. The fix
|
|
uses hash() to generate hash values for the tuple of (address, mask length,
|
|
network address).

Fix a bug where a line with only a line continuation character is not

|
considered a blank line at tokenizer level. In such cases, more than a

|
single `NEWLINE` token was emitted. The old parser was working around the

|
issue, but the new parser threw a :exc:`SyntaxError` for valid input due to
|
|
this. For example, an empty line following a line continuation character was
|
|
interpreted as a :exc:`SyntaxError`.
