[Twisted-Python] DNS changes
by Jp Calderone 30 Dec '02

30 Dec '02

I've just committed some changes to the DNS client code that are not backwards compatible. I don't think many people are using it yet (Tv is actually the only person I know of), but if you are, consider this your heads up :) The change is in all the lookup* methods - they now return a tuple of 3 lists. The first element of this tuple is the same list as was previously returned, all by its lonesome. There's also a new, high-level interface available via getHostByName(). It returns just a string.

[Twisted-Python] twisted.python.compat
by Jp Calderone 30 Dec '02

30 Dec '02

Just a heads up, the backwards compatability code (what little of it there was) in twisted.python.util has just moved to twisted.python.compat. I left a dict proxy in place that issues a deprecation warning, but all new code should use twisted.python.compat. Any future compatability code should go in this module.

[Twisted-Python] FYI: runtests on win32
by Cory Dodt 29 Dec '02

29 Dec '02

I've put up some logs of admin/runtests so that people can see how we're doing on Windows, merely to inform. You can't fix bugs if you don't know about them. :-) With the default SelectReactor... here: http://twistedmatrix.com/users/moonfallen/test.dump.txt (stderr of runtests -t) and here: http://twistedmatrix.com/users/moonfallen/test.log.txt (test.log file generated by runtests) Some of the errors are from doing obviously unix-only things like fcntl, symlinks, AF_UNIX sockets. A few others are not so obvious. Also with Win32Reactor... here: http://twistedmatrix.com/users/moonfallen/testwin32.dump.txt and here: http://twistedmatrix.com/users/moonfallen/testwin32.log.txt The additional errors in using this reactor seem to be bugs in the reactor. __________________________________________________ Do you Yahoo!?

[Twisted-Python] woven: one <input> for each ListItem
by John Kozak 29 Dec '02

29 Dec '02

Using woven, how do I create an <input/> for each Item in a List? e.g. suppose I wanted to do something like <table model="aList" view="List"> <tr> <td><input ???/></td> ... want these replicated </tr> </table> how would I go about this? I've tried a few guesses based on the examples, but aren't getting anywhere. thanks John Kozak

[Twisted-Python] t.w.widgets.Form and radio buttons
by Tommi Virtanen 29 Dec '02

29 Dec '02

I know twisted.web.widgets is deprecated, but I still have lots of code using it. So, here's a new feature: Form support for radio buttons. They work pretty much equally to checkgroups. I didn't see a point in supporting a single radio button, so I only implemented the group support. If nobody complains, I'll commit this soonish: Index: twisted/web/widgets.py =================================================================== RCS file: /cvs/Twisted/twisted/web/widgets.py,v retrieving revision 1.72 diff -u -r1.72 widgets.py --- twisted/web/widgets.py 16 Nov 2002 08:10:33 -0000 1.72 +++ twisted/web/widgets.py 29 Dec 2002 17:09:56 -0000 @@ -244,6 +244,12 @@ checked = (checked and 'checked = "1"') or '' write('<INPUT TYPE="checkbox" NAME="%s" VALUE="%s" %s />%s<br />\n' % (name, optionName, checked, displayName)) +def htmlFor_radio(write, name, value): + "A radio button group." + for optionName, displayName, checked in value: + checked = (checked and 'checked = "1"') or '' + write('<INPUT TYPE="radio" NAME="%s" VALUE="%s" %s />%s<br />\n' % (name, optionName, checked, displayName)) + class FormInputError(Exception): pass @@ -283,7 +289,8 @@ 'multimenu': htmlFor_multimenu, 'password': htmlFor_password, 'checkbox': htmlFor_checkbox, - 'checkgroup': htmlFor_checkgroup + 'checkgroup': htmlFor_checkgroup, + 'radio': htmlFor_radio, } formParse = { @@ -325,6 +332,8 @@ - 'checkgroup': a group of checkboxes + - 'radio': a group of radio buttons + - 'password': a 'string' field where the contents are not visible as the user types - 'file': a file-upload form (EXPERIMENTAL) @@ -339,8 +348,8 @@ The 'Input Value' is usually a string, but its value can depend on the 'Input Type'.

I'm not sure if writeSomeData is ever supposed to return an exception. Who was returning what?

[Twisted-Python] dict implementation buggy
by Moshe Zadka 28 Dec '02

28 Dec '02

For example, there is not a single call to self.d.errback -- there should probably be at least two, one if the connection is lost, and one if the server sends an error. However, this is the least of dict's problems -- the whole interface looks backwards, as it should probably be nicely wrapped up in a factory, so it can also errback on connection failed. I would request some more initial quality control on new protocol implementations. Thanks, Moshe Zadka

[Twisted-Python] admin/runtests on OS X
by Bob Ippolito 28 Dec '02

Just FYI on this one, as of now there's a lot less tests that fail on OS X 10.2.3 (Python 2.2). All of the SSH stuff seems to have been resolved, just a few lingering failures elsewhere..

[Twisted-Python] twisted.names.dns
by Eron Lloyd 28 Dec '02

28 Dec '02

Hi all, We are planning to support some in-house DNS service starting next year, and since I've been playing with Twisted, I recall that there used to be something along the lines of a basic DNS server built on top of twisted.names. Has this been removed, refactored somewhere else, or abandoned? Is anyone working on a production-quality but simple DNS server?
