TestFixtures 2.0.0 Released!
Hi All, I'm happy to announce a new release major release of TestFixtures. This release is 99% backwards compatible, but a lot has changed under the hood and there's some major new functionality, so thought it was time for a bump. The big changes are: - compare now uses a registry of comparers in the same way that unitest2's assertEquals does. You can register your own globally, register the default comparers for your own types and use a specific registry for a specific call to compare. - The handling of timezones has been reworked in `test_datetime` again. (did anyone ever mention that timezones are hard ;-) ) It feels more intuitive now, but it is backwards incompatible in the case where the `tzinfo` parameter to the `test_datetime` constructor was used. For details, read: http://packages.python.org/testfixtures/datetime.html#timezones The full list of changes can be found here: http://packages.python.org/testfixtures/changes.html The package is on PyPI and a full list of all the links to docs, issue trackers and the like can be found here: http://www.simplistix.co.uk/software/python/testfixtures cheers, Chris -- Simplistix - Content Management, Batch Processing Python Consulting - http://www.simplistix.co.uk -- http://mail.python.org/mailman/listinfo/python-list

Re: Python Mixins
Matt mattj.morri...@gmail.com wrote: I'm curious about what people's opinions are about using mixins in Python. I really like, for example, the way that class based views were implemented in Django 1.3 using mixins. It makes everything extremely customizable and reusable. I think this is a very good practice to follow, however, in Python mixins are achieved by using (or perhaps misusing) inheritance and often multiple inheritance. I think Mixins are great, in moderation, but wait until you have to debug code on an object with 70 base classes. Reinout van Rees wrote a very insightful article recently about Django's use of multiple inheritance: http://reinout.vanrees.org/weblog/2011/08/23/class-based-views.html He points out the problems that arise from overuse of mixins; why Zope went through so much upheaval to get away from mixins everywhere and switched to a component architecture instead; and suggests that Django will do the same in a few years time. -- Duncan Booth http://kupuguy.blogspot.com -- http://mail.python.org/mailman/listinfo/python-list

Perhaps I'm looking at wrong function. My aim is simple, I need to execute Python code using Python interpreter embedded in my C++ application. The Python code is a simple script that always returns single value. For example: #! /usr/bin/env python def foo(a, b): return a + b f = foo(2, 3) But, f can be of different type for different script: one returns numeric value, another returns a sequence, so the type is not possible to be determined in advance. I know how to capture Python stdout/stderr. I also know how to access the f attribute using PyObject_GetAttrString and then I can convert f value to C++ type depending on PyObject type. However, I guess there shall be a way to access f value directly from PyEval_EvalCode return object: PyObject* evalRet = ::PyEval_EvalCode(...); But, I can't find any details what the evalRet actually is. Eval is to eval an expression. If you simply eval the expression f in the context of the module you should get the result returned. Obviously though it is designed to eval more complex expressions and in your specific example, doing the getattr thing will also work fine. Hi Mark, So, the result of PyEval_EvalCode strictly depends on the code being evaluated. It makes sense. Thanks for help!

cProfile and name spaces.
Hi
I have following piece of code in file f1.py
# f1.py starts here ###
def f():
pass
def main():
import profile
profile.run('f()')
if __name__ == '__main__':
main()
# -- end of f1.py
executing f1.py works as expected.
Now I have a file f2.py
# f2.py starts here ###
import f1
f1.main()
# -- end of f2.py
If I run f2.py
I get the error message:
. . . .
File C:\Python26\lib\profile.py, line 70, in run
prof = prof.run(statement)
File C:\Python26\lib\profile.py, line 456, in run
return self.runctx(cmd, dict, dict)
File C:\Python26\lib\profile.py, line 462, in runctx
exec cmd in globals, locals
File string, line 1, in module
NameError: name 'f' is not defined
So cProfile doesn't find my function f any more.
I can fix this by changing the code in f1.py to
profile.run('f1.f()')
However now I can't run f1.py anymore.
Is it intentional, that cProfile always uses the name space of the
initial module?
I consider it surprising especially as I did not find any mentioning of
this particularity in the documentation, which states:
cProfile.run(command[, filename])
This function takes a single argument that can be passed to the exec
statement, and an optional file name. In all cases this routine attempts
to exec its first argument, and gather profiling statistics from the
execution. If no file name is present, then this function automatically
prints a simple profiling report, sorted by the standard name string
(file/line/function-name) that is presented in each line. The following
is a typical output from such a call:
I'm using python 2.6.5
The reason why I don't profile at the top level is, that I do not want
to profile some parts of the code and as I want to
conditionally profile a cetain function within different contexts /
applications
WI have also difficulties implementing something like this in a module,
which
is not the main module.
arg1 = f(1)
arg2 = f2()
if do_profile:
CProfile('result = function_name(arg1, arg2)', fname)
else:
result = function_name(arg1, arg2)

Re: python install on locked down windows box?
Hi Matt, Enjoyed your list options :) I'm a consultant and have to do what your subject line asks at most clients I work at. Here's the technique I recommend: Install Python for the ***current user*** on another workstation with the appropriate priviledges. Then xcopy this Python folder to a USB drive. Then xcopy this folder from your USB drive to a matching folder on your locked down workstation. The xcopy-ed version of Python will run without problems when you start the python.exe executable from a command line with a python script as a command line parameter. The only thing you won't be able to do is click on .py* files and have them automatically invoke the Python interpreter because file associations require admin rights to update the registery.

One is about how to get the encoding of a Web page: http://NikitaTheSpider.com/articles/EncodingDivination.html I also wrote an article examining the statistics I'd seen run through the crawler/validator. One thing I saw was that almost 2/3 of Web pages specified the encoding in the META HTTP-EQUIV Content-Type tag rather than in the HTTP Content-Type header. Mind you, this was three years ago so the character of the Web has likely changed since then, but probably not too dramatically. http://NikitaTheSpider.com/articles/ByTheNumbers/fall2008.html You can also do some straightforward debugging. Save the raw bytes you get from each site, and when you encounter a decode error, check the raw bytes. Are they really in the encoding specified? Webmasters make all kinds of mistakes.

Did you consider subclassing your Var class ? This is how you extend a
class behavior in OOP.
class PSIVar(var):
def __init__(self, name, desc, other=None, fun=None):
var.__init__(self, name, desc)
if other is not None:
self.other = other
self.fun = fun
assert callable(self.fun)
v1 = PSIVar('name', 'desc')
that's it.
By the way, don't create instance attribute conditionally. Your PSIVar
instance should always have a 'other' attribute, its value can be None
though.

The only reliable way I've found to start fresh is to delete at least logging from sys.modules (I can even do this from within my module). Even if the module that imports logging is deleted, things in logging persist (I can confirm at least handlers and handles to log files; the latter requiring garbage collection as well to free up). However, this would probably wreak havoc on other code that uses logging (although, I could always import logging as something else). On a side note, this actually gives me a good way to detect that the module is reloaded (I can't think of any other way to detect it, at least not off the top of my head). -- CPython 3.2.2 | Windows NT 6.1.7601.17640 | Thunderbird 6.0.2 -- http://mail.python.org/mailman/listinfo/python-list

comments on runpy module
Hi! I've just had fun with the runpy module in Python 2.7. I'm writing to share it :) What I've tried is to load a python script using runpy.run_path(), take a function from the resulting namespace and call it with arbitrary arguments. All the functions in the namespace seem to be ok. repr(namespace[f]) gives function f at 0x005531F0. But if the f() is referring the modules namespace (I supposed it is the same as the returned one), all the values appear to be None. Example script.py: def f(arg): return g(arg) def g(arg): return arg Then running main.py: import runpy namespace = runpy.run_path(./script.py) print namespace[f] print namespace[g] print namespace[f](abc) gives such an output function f at 0x005524F0 function g at 0x023F0830 Traceback (most recent call last): File main.py, line 7, in module print namespace[f](abc) File ./script.py, line 2, in f return g(arg) TypeError: 'NoneType' object is not callable Reading the Lib/runpy.py I've found, that the temporary module created inside the run_path() calls, is destroyed right after the script.py code executed in the resulting namespace.

strange behavior from recursive generator
A few weeks ago, I wrote a class that creates an iterator for solving the general unlabeled-balls-in-labeled boxes occupancy problem. Chris Rebert converted my code to a generator, which made the code cleaner, and I subsequently simplified it somewhat further. My problem is the following: All of these versions of the code work fine for very small problems, but do not produce the full set of occupancy distributions for larger problems. The following sample input and output show what happens with two balls and two boxes (to keep things simple, I've made the boxes large enough so that each box can hold both balls). In [6]: x= balls_in_labeled_boxes(2,[2,2]) In [7]: list(x) balls=2, box_sizes=[2, 2] About to make recursive call. balls_in_other_boxes=0, box_sizes=[2] i=0, distribution_other=(0,) About to make recursive call. balls_in_other_boxes=1, box_sizes=[2] i=0, distribution_other=(1,) About to make recursive call. balls_in_other_boxes=2, box_sizes=[2] i=0, distribution_other=(2,) Out[7]: [(2, 0), (1, 1), (0, 2)] Note that Out[7] above gives the correct result, showing all three possible distributions. Now lets try the same thing with three boxes.

Re: Context manager with class methods
Terry Reedy wrote: it is normal to look for special methods on the class (and superclasses) of an object rather than starting with the object itself. I suspect there was a deliberate change to correct an anomaly, though this might have been done as part of some other change. It's a necessary consequence of the fact that new-style classes are also instances. Without it, there would be an ambiguity as to whether a special method defined the behaviour of instances of a class or of the class object itself. It also increases efficiency, because for those special methods that correspond to C-level type slots, you only have to look in the type slot to find an implementation of the method, rather than having to look in the instance dict first. -- Greg -- http://mail.python.org/mailman/listinfo/python-list

[issue13034] Python does not read Alternative Subject Names from SSL certificates larger than 1024 bits
New submission from Andrea Trasatti atrasa...@gmail.com:
We found a problem with SSL certificates, when they are larger than 1024 bits
and you need to check Alternative Subject Names.
In our case we have a 2048 bit certificate, issued by Verisign for the domain
developer.nokia.com. The certificate also covers other sub-domains, once of
which is projects.developer.nokia.com. We found the issue using the mercurial
client, but we dug down to SSLSocket.getpeercert. It looks like when the
openSSL library reads the certificate it does not return any Alternative
Subject Name, even though they are there. Using the standard openssl binary we
could read the certificate with no problems and the alternative domain names
are all there, including the one we need.
See below two examples, the first is our 2048 bit certificate and what Python
returns. Then there is Google's code.google.com SSL certificate, 1024 bits and
as you can see Python returns the other names correctly.
This was tested with Python 2.7.2.
Binary for projects.developer.nokia.com

[issue13036] time format in logging is wrong
New submission from Yves Dorfsman y...@zioup.com:
The basic time format in the logging module uses a comma instead of a dot to
separate the seconds from the tenth of seconds:
import logging
logging.basicConfig(format='%(asctime)s %(message)s')
logging.warning('hello')
2011-09-23 09:08:53,739 hello
Using a dot seems to be more accepted, see:
ls -l --full-time
Java's default dates
python's datetime.datetime.isoformat( datetime.datetime.now() )

[issue7732] imp.find_module crashes Python if there exists a directory named __init__.py
Barry A. Warsaw ba...@python.org added the comment: Note that Python 2.6 is also vulnerable to the crash. While we do not have an exploit, we did get a report on security@ which led to this bug. I could be convinced to allow the patch to 2.6 on grounds that if the crasher can be exploited, better to apply it now rather than wait. Certainly if it's easier to apply 2.6 and forward port, I'm fine with that. Victor's pyfile_fromfile_close.patch looks good to me and fixes the problem with no discernible ill effects. On IRC, he said he'll apply it to 2.7, 3.2, and 3.3. I will approve it for 2.6 if he wants to apply it there too. -- nosy: +barry versions: +Python 2.6, Python 3.1 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7732 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11725] httplib and urllib2 failed ssl connection httplib.BadStatusLine
Isaac Salsberg isalsb...@users.sourceforge.net added the comment: The output for the command: $ openssl s_client -connect www.finratrace.org:443 was the same on MAC OS X 10.6 and on Red hat 5 (https works fine under linux). Nevertheless, Ned Deily is right: the bug is on the openssl libs supplied with OS X 10.6 To solve this issue, I compiled and install OpenSSL 1.0.0d and then link python against this library. This is the full recipe, step by step: 1. Install openssl. Download the source tar for openssl. I used version openssl-1.0.0d. To build 64-bit library, then you have to invoke './Configure darwin64-x86_64-cc' *manually*. Also, to make ssl work in python, the openssl libraries must be 'shared libraries'. First, Expand the tar file into a temporary directory, I am using /tmp: $ cd /tmp $ tar xvzf openssl-1.0.0d.tar.gz $ cd openssl-1.0.0d To Build openssl as 64 bits shared libraries and install it: $ ./Configure darwin64-x86_64-cc shared $ make $ make test # this step is optional $ sudo make install This will install openssl in the default directory: /usr/local/ssl 2. Compile and install python. Download the source tar file. I used version Python 2.7.2 a) Expand the tar file (again into a temporary directory) b) then go into the Modules folder c) vi the Setup.dist file, looking for the SSL string (if your are not familiar with vi, you can use any text editor), then uncomment the lines BELLOW the message: # Socket module helper for SSL support ... Your file must look as follows: # Socket module helper for SSL support; you must comment out the other # socket line above, and possibly edit the SSL variable: SSL=/usr/local/ssl _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto d) Then using python defaults (installing under /usr/local) execute: $ ./configure $ make $ make test # optional $ sudo make install 3. To test if python now has ssl support, start python and execute these commands (be sure you invoke the new python under /usr/local/bin): imac:~ isaac$ /usr/local/bin/python Python 2.7.2 (default, Jun 30 2011, 16:00:06) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type help, copyright, credits or license for more information. import httplib hasattr(httplib, 'HTTPS') True # MUST be True, otherwise has NO ssl support ... import socket hasattr(socket,'ssl') True # MUST be True, otherwise has NO ssl support ... import _ssl # should NOT give any error when importing ...

Apart from that, this looks like a vast improvement to me. As far as not supporting globs goes, I guess I don't really care either way. If globs aren't supported, then I'll probably end up globbing somewhere else (or constructing the full upload list in some other automated way).

[issue10141] SocketCan support
Charles-François Natali neolo...@free.fr added the comment:
- dummy question: why an address is a tuple with 1 string instead of just
the string? Does AF_UNIX also uses a tuple of 1 string?
I think the reason behind the tuple is future proofing.
Here's the definition of `struct sockaddr_can` in my Linux box's headers:
/**
* struct sockaddr_can - the sockaddr structure for CAN sockets
* @can_family: address family number AF_CAN.
* @can_ifindex: CAN network interface index.
* @can_addr:protocol specific address information
*/
struct sockaddr_can {
sa_family_t can_family;
int can_ifindex;
union {
/* transport protocol class address information (e.g. ISOTP) */
struct { canid_t rx_id, tx_id; } tp;
/* reserved for future CAN protocols address information */
} can_addr;
};
By making it a tuple, it will be easier to extend the address that
must be passed to bind(2), should it ever evolve, in a backward
compatible way. Well, that's just a guess (I'm by no means a SocketCAN
expert :-).
- the example should also use struct.pack() to create the frame, I don't
like hardcoded BLOB
Done.
- in test_socket: _have_socket_can() interprets permission denied as CAN
is not supported, it would be nice to provide a better skip message. Create
maybe a decorator based?
AFAICT, it shouldn't fail with EPERM or so.
Also, I'm not sure what the message would look like, and it's probably
a bit overkill.
- _have_socket_can(): you may move s.close() outside the try block (add
maybe a else: block?) because you may hide a real bug in .close()
Changed that.
- data += b'\0' * (8 - can_dlc): I prefer data = data.ljust(8, '\x00')
Hum... Done.
- you might add frame encoder/decoder in your example
Done.
- if (!strcmp(PyBytes_AS_STRING(interfaceName), )) hum.
PyBytes_GET_SIZE(intername)==0 should be enough
Done.
- you truncate the interface name, it can be surprising, I would prefer an
error (e.g. interface name too long: 20 characters, the maximum is 10
characters ?)
I changed that, and added a test. Also, note that AF_PACKET suffers
from the same problem.
I'll submit a separate patch.
- (oh no! don't include horrible configure diff in patches for the bug
tracker :-p)
Yeah, I usually take care of that, but forgot this time.
In which Linux version was CAN introduced?
Apparently, 2.6.25. Note that we don't need
@support.requires_linux_version() though, it should be catched by
HAVE_SOCKET_CAN (also, you can't use it as a class decorator...).
Here's the updated patch. It passes on all the buildbots (of course,
it's only relevant on Linux).

[issue13038] distutils windows installer STATUS_INVALID_CRUNTIME_PARAMETER (C0000417) exception when python dir is read only
New submission from Mitch Frazier mi...@comwestcr.com: Distutils built installers will fail on Windows with a run-time exception of STATUS_INVALID_CRUNTIME_PARAMETER, error-code: C417 if the python installation directory (e.g. C:\Python27) is read-only for the user running the installer. I've experienced this with the pyside and pywin32 installers on Windows XP. Using procmon I discovered that the installer fails when it tries to create the installation log file in the python install directory. That led me to look at the directory which is when I discovered that it was read only for my user account. It's read-only because the Python installer was run as Administrator and the other installers are being run from my user account. Changing the directory to read-only for my account allows the installer to run without problem. Perhaps the installer could check for this and provide a friendlier response. -- assignee: tarek components: Distutils messages: 144477 nosy: eric.araujo, mitchfrazier, tarek priority: normal severity: normal status: open title: distutils windows installer STATUS_INVALID_CRUNTIME_PARAMETER (C417) exception when python dir is read only type: crash versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13038 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
