So, in the end, I have went the long way and bisected cpython to find the commit which broke my tests, and it seems that the culprit is http://hg.python.org/cpython/rev/123f2dc08b3e so it is clearly something Unicode related.

pyOpenSSL -> m2crypto conversion?

Is there some HOWTO/blogpost/examples of doing so, or is there some help in m2crypto for that? Both libraries are bindings over OpenSSL, so I hope it wouldn't be that difficult. https://bugs.launchpad.net/pyopenssl/+bug/236170/comments/22 seems to suggest that there might be some pyOpenSSL compatibility wrapper for m2crypto ... do I understand it correctly?

I don't think it is a proper description of the situation (please, somebody correct my mistakes, I am not 100% sure about it myself). WSGI applications (which is basically all web applications in Python) could run in the hosted servers (using for example mod_wsgi for Apache), and I would expect that it is the situation with most production uses. From the programmer's point of view WSGI application (read http://en.wikipedia.org/wiki/Wsgi) is just one script which takes HTTP request on input and generates HTTP Response on output, so it is actually quite simple. And actually quite similar to what JSGI, PSGI, and Rake do (I am not sure who was first whether WSGI or Rake). anyway... why did Python solutions go for long-running processes while PHP was built from the start as short-running processes? It is all about caching ... I am not sure how it is done exactly, but I would expect for example mod_wsgi to cache parsed Python script in memory as well.

But nobody is interested in you knowing a language, you need to know the platform with all libraries, standards, style, and culture. And *that* demands you focus on one language completely. Yes, of course, you will know couple of other languages and be able to write a thing in it (everybody needs to know a bit of JavaScript these days, and if you are on Unix/Linux,Mac OS X, you need to know a bit of shell scripting), but that's different from "Zen & Writing" (that's my personal homage to recently deceased Ray Bradbury and his essay http://www.worldcat.org/search?qt=wikipedia&q=isbn%3A1877741094).

It is not only matter of unit tests, but I would really welcome if the results on both versions produce the same results. Could we get some hint in the release notes? Thanks for the help, Matěj -- http://mail.python.org/mailman/listinfo/python-list
difference between random module in python 2.6 and 3.2?
Hi,
I have this working function:
def as_xml(self):
out = etree.Element("or")
for k in sorted(self.keys()):
out.append(etree.Element("hostname",
attrib={'op': '=', 'value': random.choice(self[k])}))
# ... return somehow string representing XML
and this unit test
def test_XML_print(self):
random.seed(1)
expected = ... # expected XML
observed = self.data.as_xml()
self.assertEqual(observed, expected,
"Verbose print (including PCI IDs)")
Strange thing is that this unit tests correctly with python3, but fails
with python2. The problem is that apparently python3 random.choice picks
different element of self[k] than the one python2 (at least, both of
them are constant in their choice).
Is it known that there is this difference? Is there a way how to make
both random.choice select the same?
Best,
Matěj

Python and TAP
I have just finished listening to the FLOSS Weekly podcast #200 (http://twit.tv/show/floss-weekly/200) on autotest, where I've learned about the existence of TAP (http://testanything.org/). A standardization of testing seems to be so obviously The Right Thing™, that it is strange that I don't see much related movement in the Python world (I know only about http://git.codesimply.com/?p=PyTAP.git;a=summary or git://git.codesimply.com/PyTAP.git, which seems to be very very simple and only producer). What am I missing? Why nobody seems to care about joining TAP standard? Best, Matěj -- http://mail.python.org/mailman/listinfo/python-list

Thanks for your help, but plain-text strings is not what
I wanted. The boolean variables was what I was after. See this
modified version of the script:
#!/usr/bin/python
import sqlite3
def adapt_boolean(bol):
if bol:
return "True"
else:
return "False"
def convert_boolean(bolStr):
if str(bolStr) == "True":
return bool(True)
elif str(bolStr) == "False":
return bool(False)
else:
raise ValueError, "Unknown value of bool attribute
'%s'" % bolStr
sqlite3.register_adapter(bool,adapt_boolean)
sqlite3.register_converter("boolean",convert_boolean)
db = sqlite3.connect(":memory:")
cur=db.cursor()
cur.execute("create table test(p boolean)")
p=False
cur.execute("insert into test(p) values (?)", (p,))
p=True
cur.execute("insert into test(p) values (?)", (p,))
cur.execute("select p from test")
for (field,) in cur.fetchall():
print field,type(field)
The output here is:
[EMAIL PROTECTED] dumpBugzilla]$ python testAdaptors.py False
True
[EMAIL PROTECTED] dumpBugzilla]$
I thought that converter is there for just exactly this -- that
I would get back bool values not strings.
Sorry for not being clear in the first run.

sqlite3 adaptors mystery
Hi,
I am in the process of creating a small script for filling the
sqlite3 database with data from rather large XML-RPC query (list
of many bugs from the Red Hat Bugzilla) and I would love to use
adaptors and converters for some data types which I am missing.
I have this test script (made hopefully pretty faithfully from the
documentation):
#!/usr/bin/python
import sqlite3
def adapt_boolean(bol):
if bol:
return "True"
else:
return "False"
def convert_boolean(bolStr):
if str(bolStr) == "True":
return bool(True)
elif str(bolStr) == "False":
return bool(False)
else:
raise ValueError, "Unknown value of bool attribute '%s'" \
% bolStr
sqlite3.register_adapter(bool,adapt_boolean)
sqlite3.register_converter("boolean",convert_boolean)
db = sqlite3.connect("test.db")
cur=db.cursor()
cur.execute("create table test(p boolean)")
p=False
cur.execute("insert into test(p) values (?)", (p,))
p=True
cur.execute("insert into test(p) values (?)", (p,))
cur.execute("select p from test")
print cur.fetchall()
And I would expect to print on output representation of bool values, i.e.,
something like
[False,True]
However, when running this program it seems converter doesn’t seem to work,
because I get:
[EMAIL PROTECTED] dumpBugzilla]$ rm test.db ; python testAdaptors.py
[(u'False',), (u'True',)]
[EMAIL PROTECTED] dumpBugzilla]$
There is probably something quite obvious what I do incorrectly, but I just
don't see it. Could somebody kick me in the right direction, please?
Thanks a lot,

Is there somewhere support for the extension of email module, which would support writing to (and creating new) mbox folders (with all bells and whistles, like locking)?

PyKDE inside vim-python
Hi,
did anybody tried %subj%? I have created really stupidly simple dialog-box
in Qt-designer (it is available on
<http://www.ceplovi.cz/matej/tmp/KDE-dialog.tar.gz>) and I would like to
run it from vim-script in kvim (soon to be obsoleted and replaced by
Gnome-vim; oh, well, I liked kvim). Of course I can do something like
:let cat = system("categorySet.py")
but I thought that running the script directly from vim (with Python
scripting enabled) could make this script faster. Can anybody help me,
whether it is possible to do something like this?
Thanks,
Matěj

Seekable output from ClientForm?
Hi,
using python 2.3, ClientForm, and ClientCookie and I have this code:
opener = ClientCookie.build_opener(ClientCookie.HTTPRefererProcessor,
ClientCookie.HTTPRefreshProcessor,
ClientCookie.SeekableProcessor)
response = opener.open(lxURL)
forms = ClientForm.ParseResponse(response)
form = forms[0]
response.seek(0)
form['extpatid'] = MyNEUlogin
form['extpatpw'] = MyNEUpassword
formopener = form.click()
response2 = ClientCookie.urlopen(formopener)
guidednews = re.compile("s_guidednews.html")
response2.seek(0)
h = htmllib.HTMLParser(formatter.NullFormatter())
h.feed(response2.read())
print h.anchorlist
Unfortunately, it doesn't work, because response2 was created by
ClientForm and it is not seekable (apparently, I get "AttributeError:
addinfourl instance has no attribute 'seek'").
How to make output of ClientForm seekable, please?
Thanks a lot,
Matej
