Python RPM distribution with altinstall on Centos 5
Hi all, I missed to find a Python 2.7.6 Centos 5 distribution. Here's what I planned to do: - building from source on Centos 5 in a chroot (is working fine) - using "sudo make altinstall" (is working fine) But ... - I want to build this via Jenkins (we have this kind of chroot build's still in place) - how to create a RPM for this concrete Centos 5 - Python version with the "altinstall" feature? (!! we require this !!) Maybe you also have another idea on how to solve this Kind Regards, Thomas -- https://mail.python.org/mailman/listinfo/python-list
Pylint across Python versions
Hi,
somebody who can tell me about pylint experiences across
different Python version.
Example:
I'm using a construct like this:
if sys.version.startswith("3."):
unicode = str
The reason is that Python 3 does not have this
function anymore but pylint yells for Python < 3
about redefinition also it does not happen.
How to get forward with this?
Regards,
Thomas

bdist_rpm with --requires and version
Hi, using the RPM build I wonder how I can require a certain version of another RPM like: Working: python setup.py bdist_rpm --requires=another-package But how to? ... python setup.py bdist_rpm --requires=another-package>=2.1 Of course this will generate a "=2.1" file which is of course not wanted.

Re: Why Python 3?
Hi, I can't give you the advise for a concrete version anyway there are lot of arguments given by the other posters. BUT there is a way how you can circumvent the problem to some extend: Are you intending to use Jenkins? I don't want to convince you here why to use Jenkins but maybe I don't need to and THEN you just install the ShiningPanda plugin and each time your project is build automatically because of a change all tests are running across multiple Python versions. This way you won't have too many problems to switch to another newer Python version. Keep the build "green". > > What is the general feel of /this/ community?

Advanced Dictionary
Hi,
I have seen a recipe which allows auto creation of missing values for
dictionaries.
However this recipe is not working for all.
class AutoValueDict(dict):
def __makeitem__(self, key):
return self.setdefault(key, {})
def __getitem__(self, key):
return self.get(key, self.__makeitem__(key))
I would like to have a dictionary which ensures dictionaries as values
except when I'm assigning another:
dict["abc"]["xyz"]["123"]["456"] = 123
How can I do this without many "if" and "else"?

Decode II (more complex)
Hi all,
I have written a small python xmlrpc server which checks logfiles of a
build
sending notifications to the responsible teams. On a machine I'm
forced to
a problem with one logfile with special characters inside generated by
a
gnu compiler.
Using cheetah for generating the HTML mail I get a:
('ascii' codec can't decode byte 0xe2 in position 25868: ordinal not
in range(128))
I have found characters like this:
error: expected type-specifier before â<80><98>Assocâ<80><99>
(copy and paste of a linux console)
I have tried different mechanism but very probably I do not understand
how the decode/encode functionality is working. Can somebody help me
to get out of that problem?
Thanks in advance

I can not say too much because I don't see what is processed
but what I can say is: "line.split(',')[1].strip()" might be
called three times so I would do it once only. And I would write
it like this:
for line in outf:
key = line.split(',')[1].strip()
if not (key in universe.keys()):
if not (key in done_.keys()):
universe[key] = 0

Fast Dictionary Access
Hi! In C++, programming STL you will use the insert method which always provides a position and a flag which indicates whether the position results from a new insertion or an exisiting element. Idea is to have one search only. if data.has_key(key): value = data[key] But this does mean (does it?) that the dictionary is searched two times!

Tkinter only: table widget with canvas...
My intention is to keep dependencies low that means using python and tkinter as base package is quite easy because it's available on nearly every system. There is good documentation on Tkinter but going into the depth I'm missing many details. As an example... Using the Tkinter.Canvas class I should be able to create a nice table. The missing informations are: a) Assume I would have some different widgets to add per row. How do I get the maximum row height? b) Assume something like a label in one column. The length of all texts in a column will differ. How do I choose the maxium column width? c) Placing headers in a canvas does not look like a good idea because I don't want to scroll the headers. Am I right? c.1) How do I place a none scrollable header in a canvas? or c.2) How do I place all headers outside the canvas correctly above the relating column? best regards Thomas -- http://mail.python.org/mailman/listinfo/python-list

Thank you very much!
However, the result is not that pretty as I have expected. The bullets
are really small. When separating bullet and text then I can increase
the font size for the bullet but then it does not fit to the text -
vertical alignment is wrong. Also it's pretty unhandy to adjust the
margins so that the text continues on next line starting at the same
position as the first character from previous line.
But it is a starting. I will check whether it is possible to place an
image for a bullet. The size and position handling will be still there
then - I think so.
Also note: The tab value from your example has not been accepted (s.th
like. "invalid screen distance")

xmlrpc: problems with socket handling, close, shutdown of server, TIME_WAIT, ...
Hi,
taking the xml-rpc derived from standard example is working - basically - but
with following scenario I do not understand the problem. Maybe you can help:
- one Unittest that does create the xmlrpc server in a thread
in "setUp" and shutdown of it in tearDown.
The xml-rcp server does store/load a value for a key.
(It's for testing/learning purpose)
Problem(s):
- If I run the test method twice (copy and paste and rename)
then I get a "error: [Errno 98] Address already in use"
(I assumend the tearDown would have closed all sockets)
- Because of this I removed that second method and so it's fine
but checking with "netstat -n | grep " I see as many
sockets in TIME_WAIT as I did xml-rpc calls. Also that python
test is not running anymore it take some time until those
entries vanish from the netstat list.
Question(s):
I assumed that calling the shutdown of the server (in tearDown)
does close all sockets. The SimpleXMLRPCServer is derived from
SocketServer.TCPServer and those one is derived from BaseServer.
Those has the shutdown which is documented to stop the serve_forever loop.
Is this correct or do I have to shutdown in another way?
At client side I'm using the ServerProxy. It does obviously not
have a "close". From code it looks like that I could do something
like "proxy("close")()" but that looks somehow wired?
Can I close a proxy?, should I?, ... what is the way?

Mock object but also assert method calls?

How about asserting that test2 of class Bar is called?
Of course I can do a patch for a concrete method but
I was looking for something like:
mocked_object.assert_method_called_with(name="test2", "hello")
If find following totally different to the normal API which
is provided by the mock library:
assert call().test2("hello") in mocked_objects.mock_calls
Is there a better way?

Foo delegates calls to Bar.

from mock import patch
with patch("__main__.Bar") as mocked_object:
foo = Foo()
foo.test1()

# print all calls (c'tor as well as normal methods)
for name, args, kwargs in mocked_object.mock_calls:
print(name, args, kwargs)
[/code]
Generates:
test1: Foo has been called
test2: Foo has been called with value hello
[call(), call().test1(), call().test2('hello')]
('', (), {})
('().test1', (), {})
('().test2', ('hello',), {})

Of course you do NOT use assert in unit tests but I provided
just test code to show my problem. Of course I take nose and
hamcrest and code coverage ...
Here a complete example of my problem (with comments):
from mock import MagicMock, call, patch
class Bla:
def test1(self, value):
pass
mocked_object = MagicMock(Bla)
bla = Bla()
bla.test1("hello")
# empty, why?
print(mocked_object.mock_calls)
# does not work: mocked_object.test1.assert_called_with("hello")
with patch("__main__.Bla") as mocked_object:
bla = Bla()
bla.test1("hello")
# not empty!
print(mocked_object.mock_calls)
# does also not work: mocked_object.test1.assert_called_with("hello")
# but this does work:
assert call().test1("hello") in mocked_object.mock_calls
I don't wanna patch each individual method. Is there no other way?
