I would shorten "origin_sign" to just "sign".
Sign of what? Decay? :-) I don't think that sign is descriptive
enough,
I would personally stick with origin_sign.
Whoops, I meant "origin". The "_sign" bit seems a little bit
redundant to me.
"Origin" is an established term for the name of the parent.
name = "blabla.example."
origin of "name" = "example."
Anyway, I still think that DNSName('@') is better than any constant
with cryptic name.
Honza, can you see any problem with this? I know this creates instance
again and again, but is it a real problem? I would like to avoid
premature optimization... :-)
What about making all these fixed names as constants and then simply
return those?
class DNSName:
DNS_ORIGIN = DNSName('@')
...
@staticmethod ...
def ...
return DNS_ORIGIN
they would be singletons...
Unfortunately you can't do that, because at the time DNSName is
parsed, it is not defined yet:
class X:
... x = X()
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in X
NameError: name 'X' is not defined
Then we can split these classes: define DNSName with purely static
methods as child of DNSNameBase which would have all the expected
methods. DNSName can then have constants of DNSNameBase() and return
those.
IMO this is an overkill. I would prefer if we did what I suggested
earlier: put DNSName into a new module dnsutil and make the constants
global for the module.
