Hello, I realize I may have missed some kind of formal announcement, but why have all the buildbots been down for a number of days (weeks?) now? Thanks Antoine.

how to debug httplib slowness
by Chris Withers 18 Sep '09

18 Sep '09

Hi All, I'd like to work on this issue: http://bugs.python.org/issue2576 Specifically, in my case, while IE can download a 150Mb file from a local server in about 3 seconds, httplib takes over 20 minutes! However, I'm kinda stumped on where to start with debugging the difference. I've tried upping the buffer size as suggested in the issue, but it's had no effect... Any ideas?

Please can we have the following RFCs added to the references section that cover many of the aspects covered by this PEP? RFC 791 - Internet Protocol RFC 1918 - Address Allocation for Private Internets RFC 3330 - Special-Use IPv4 Addresses RFC 4291 - IPv6 Addressing Architecture RFC 4632 - Classless Inter-domain Routing (CIDR): The Internet Address Dave M.

I'm happy to see indexing made available alongside specific properties/methods that expose the network (without mask) and broadcast addresses for a given network object, but not to remove them from the interface entirely in favour of indexing alone. While it seems like a good idea, in practice it just won't work or will at least be sub-optimal and violates the rule of least surprise (for IP libraries anyway). I struggled along with this approach in several early versions of netaddr but had to cave in to pressure from users after repeated questions about where to find the broadcast and network (without mask) addresses! Granted, there are decisions to be made about exactly what the properties/methods should be named to avoid ambiguity, but they are important enough to be given access to in their own right. Details in docstrings help too ;-) 'network' and 'broadcast' are very much the convention used pretty much everywhere (including libraries found in other languages such as Ruby and Perl). IPv6 doesn't support the notion of a broadcast address as part of a CIDR network block at all. AFAIK, it is a perfect legitimate for the last address in an IPv6 block to be used to configure a network interface. The IPv6 network object interface should possibly leave out the broadcast property/method altogether although there are reasons to keep it in for the sake of completeness and API consistency. The pros and cons of this need to be considered. BTW, has anyone considered use of the term *CIDR to refer to an address + mask object? It would certainly be less controversial than *Network which already has too many overlapping meanings elsewhere in the interface? Obviously we'd still have the issue of what to do with the host bits to the right of the supplied mask (keep or discard). This is not a clear cut choice of one or the other as it is entirely based on context. For configuring routes, you would likely always want to discard these bits (or at least Cisco does when adding routes). For configuring a network interface you would most certainly want to keep them! > Cheers, > Nick. > > -- > Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia > --------------------------------------------------------------- > _______________________________________________ > Python-Dev mailing list > Python-Dev(a)python.org > http://mail.python.org/mailman/listinfo/python-dev > Unsubscribe: > http://mail.python.org/mailman/options/python-dev/drkjam%40gmail.com >

re.Scanner and string.Template
by nathan binkert 17 Sep '09

17 Sep '09

I've been working on code that works a lot like string.Template and in the process, I stumbled on re.Scanner. I have two questions. 1) Is re.Scanner ever going to be official? Can I count on it being in future versions of python? It's been there for a really long time, so I assume so, but something that's undocumented seems that it could be dropped easily. 2) Is there a reason that string.Template doesn't use re.Scanner? My understanding of re.Scanner is that it is exactly what you want for something like string.Template. Thanks, Nate Binkert

Hello, How about allowing all authenticated users update dependency field in Python tracker? http://bugs.python.org/issue?@sort0=dependencies&@sortdir0=on&@sort1=&@grou… Looks like developers with access don't have enough time to track issue dependencies. --anatoly t.
