find method for lists
by Skip Montanaro July 25, 2001

July 25, 2001

This has probably been discussed before, but why doesn't the list object support a find method? Seems like if a non-exception-raising index method is good enough for strings, it should be good enough for lists as well. I realize I can use "l.count(x) and l.index(x)" to avoid the possible ValueError. (Or maybe it's strings that shouldn't have find, but can't be deleted not for code breakage reasons?) I'm mostly just curious. Am I missing something? Skip

A future division proposal
by Perry Greenfield July 25, 2001

July 25, 2001

Clearly the issue of changing the semantics of division is a very [ahem] divisive one in the Python community. It seems to me that providing a foolproof way of providing backwards compatibility would go a long way to reducing the ire of those with a lot of code to inspect and change. I'm not particularly thrilled with the suggestions made so far. Suggesting that people continue to use an older version of Python if they have a problem with it is especially unsatisfying. Eventually that older … [View More]

Memory leaks?
by Martin Sj�gren July 25, 2001

July 25, 2001

I'm a bit curious about the memory handling of the Py_InitModule4... When adding methods, if PyCFunction_New fails, NULL is returned without the module object being DECREF'd, and similarly, if the PyDict_SetItemString fails, NULL is returned without neither module object nor function object being DECREF'd. Is this a problem, or is this taken care of somewhere else? -- Martin Sjögren martin(a)strakt.com ICQ : 41245059 Phone: +46 (0)31 405242 Cell: +46 (0)739 169191 … [View More]

Opening sockets in protocol-independent manner (was: BaseHTTPServer.py etc)
by Martin von Loewis July 25, 2001

July 25, 2001

> Excuse my ignorance, but: A case for refactoring? Certainly, but it is debatable what exactly the best refactorization is. Abstractly, these fall into two cases - open a stream connection to some address (aka "client socket") - open a server socket to wait for incoming clients Either of these may find that it opens AF_INET, AF_INET6, or AF_UNIX sockets, depending on the values of host and port, and depending on what name lookup returns. Also, similar procedures are required for opening … [View More]

IPv6 committed
by Martin v. Loewis July 25, 2001

July 25, 2001

Hi itojun, As you may have noticed, I just committed the last chunk of your IPv6 patch. Thanks a lot for your contributions, I think you've provided a highly valuable contribution to Python 2.2. We still have to figure out a way to provide documentation, but I expect that we can complete that before 2.2a2. As with all new code, there may occur some problems; I hope you'll be around for the coming weeks and give the professional advise that you've provided throughout the integration of the … [View More]

post mortem after threading deadlock?
by Skip Montanaro July 25, 2001

July 25, 2001

Is there any possibility of getting some post-mortem info out of a multi-threaded system whose threads are deadlocked? I am trying to multi-thread my xmlrpc server methods. It's working okay "almost all the time" and I see a wonderful overall throughput boost because slow operations tend to no longer impede fast ones. I got a deadlock today, however, and am wondering how I am going to go about figuring out what happened the next time this happens. The main thread never deadlocks. It just … [View More]

mail.python.org black listed ?!

Since yesterday evening I haven't received any email from mail.python.org.
