Re: building a web interface
Shel wrote: Hello, I am pretty new to all this. I have some coding experience, and am currently most comfortable with Python. I also have database design experience with MS Access, and have just created my first mySQL db. So right now I have a mySQL db structure and some Python code. My end goal is to create a browser-based interactive fiction/game thing. My code is currently just using dummy data rather than pulling in data from the db, but I think/hope it won't be too big of a deal to interact with the db through Python (famous last words...). My main problem right now is how to do the web interface. I don't know much about web architecture, unfortunately. I think I need a CGI script? What I would really like is to find a GUI tool to design the interface that would have customizable templates or drag-and-drop elements or something, so I wouldn't have to code much by hand. Something easy, if such a tool exists. Also would prefer something that I would be able to install/use without having much access to the server where the site will be hosted (on a university server that I don't have control over). I don't fully understand how a lot of the tools I have been looking at work, but it seems like they're often things where you'd have to get an administrator to do stuff on the server (is that right?), which I would prefer to avoid. It looks like Django has some sort of standalone implementation, but I'm not clear on how that would work or how much of a learning curve there would be for using it. If anyone has any thoughts or suggestions, I would really appreciate it. Hope my questions make sense. I don't really know what I'm doing, so could be they're a bit silly. I apologize if that's the case, and please let me know if you need any additional informmation. Thanks, Shel Django is quite popular, they claim to be easy to learn/use. That's for the web framework. You could use pyjamas for the web interface, looks like it works well with django. Hmm, writing python code only, sounds like a dream come true :D Note that I never used one of these, it just happened I had to look for possible solutions for a web application.

Accepting a SAML 2 Assertion
Hello, I am working on providing a SSO solution to a customer who acts as an identity provider. He already has IDP on his side to generate SAML 2 assertions with user first name , last name and time stamp as parameters. Our task is to accept this assertion which is signed, decrypt it and send it to the authenticator we already have. The authenticator validates the info and gives access to our application which is written using Python. Here we act as the *service provider.* I am new to SAML and have no idea how to integrate SAML to our current Python application. Can you help me on how to accept these assertion requests from the Idp and decrypt it at Service Provider end using Python. Thanks -- http://mail.python.org/mailman/listinfo/python-list
Re: multiple times subprocess fails on windows
To be more specific, I have something like this in rvirtualenv itself
(that's the pokus.py file):
import os
os.system(echo 128)
I generate a batch file like this (that's the pokus.bat file):
@echo off
pokus.py
And after that, I run the pokus.bat file from a test (that's the
run.py file):
from subprocess import Popen, PIPE
p = Popen('pokus.bat', stdout=PIPE, stderr=PIPE, shell=True)
stdout, stderr = p.communicate()
print stdout.strip()
And the problem is, that I don't receive the output of the os.system
to the PIPE. Probable there is something different on windows stdout
redirection, because similar stuff works on linux..

unittests with different parameters
Hi! I'm writing tests and I'm wondering how to achieve a few things most elegantly with Python's unittest module. Let's say I have two flags invert X and invert Y. Now, for testing these, I would write one test for each combination. What I have in the test case is something like this: def test_invert_flags(self): test flags to invert coordinates tests = [((10, 20), INVERT_NONE, (10, 20)), ((10, 20), INVERT_X, (-10, 20)), ((10, 20), INVERT_Y, (10, -20))] for input, flags, expected in tests: res = do_invert(input, flags) self.assertEqual(res, expected, %s caused wrong results % (flags,)) So, what I do that I test the function 'do_invert' for different input combinations and verify the result. The ugly thing is that this will abort the whole test if one of the tests in the loop fails. So, my question is how do I avoid this? I know that I could write a common test function instead: def _test_invert_flags(self, input, flags, expected): res = do_invert(input, flags) self.assertEqual(res, expected) def test_invert_flags_non(self): test not inverting coordinates self._test_invert_flags((10, 20), INVERT_NONE, (10, 20)) def test_invert_flags_x(self): test inverting X coordinates self._test_invert_flags((10, 20), INVERT_X, (-10, 20)) def test_invert_flags_y(self): test inverting Y coordinates self._test_invert_flags((10, 20), INVERT_Y, (10, -20)) What I don't like here is that this is unnecessarily verbose and that it basically repeats information. Also, I'd rather construct the error message from the data instead of maintaining it in different places, because manually keeping those in sync is another, errorprone burden. Any suggestions?

Let it fail, fix it, then re-run the test to find the next failure. Perhaps not as efficient as finding them all at once, but you're going to fix them one at a time anyway, so what does it matter?

Imagine all tests that use INVERT_X fail, all others pass. What would your educated guess be where the code is wrong? ;) Well, let me leave you with one last thought. There's really two kinds of tests -- acceptance tests, and diagnostic tests. I tend to write acceptance tests first. The idea is that if all the tests pass, I know my code works. When some test fails, that's when I start digging deeper and writing diagnostic tests, to help me figure out what went wrong. The worst test is a test which is never written because it's too hard to write. If it's easy to write a bunch of tests which verify correct operation but don't give a lot of clues about what went wrong, it might be worth doing that first and seeing what happens. If some of the tests fail, then invest the time to write more detailed tests which give you more information about each failure. -- http://mail.python.org/mailman/listinfo/python-list

Re: unittests with different parameters
On 11/22/2010 4:38 AM, Ulrich Eckhardt wrote: Let's say I have two flags invert X and invert Y. Now, for testing these, I would write one test for each combination. What I have in the test case is something like this: def test_invert_flags(self): test flags to invert coordinates tests = [((10, 20), INVERT_NONE, (10, 20)), ((10, 20), INVERT_X, (-10, 20)), ((10, 20), INVERT_Y, (10, -20))] for input, flags, expected in tests: res = do_invert(input, flags) self.assertEqual(res, expected, %s caused wrong results % (flags,)) So, what I do that I test the function 'do_invert' for different input combinations and verify the result. The ugly thing is that this will abort the whole test if one of the tests in the loop fails. So, my question is how do I avoid this? I know that I could write a common test function instead: def _test_invert_flags(self, input, flags, expected): res = do_invert(input, flags) self.assertEqual(res, expected) def test_invert_flags_non(self): test not inverting coordinates self._test_invert_flags((10, 20), INVERT_NONE, (10, 20)) def test_invert_flags_x(self): test inverting X coordinates self._test_invert_flags((10, 20), INVERT_X, (-10, 20)) def test_invert_flags_y(self): test inverting Y coordinates self._test_invert_flags((10, 20), INVERT_Y, (10, -20)) What I don't like here is that this is unnecessarily verbose and that it basically repeats information. The above code looks perfectly fine to me for testing. I think the question you should ask yourself is whether the different combinations you are testing represent tests of distinct behaviors, or tests of the same behavior on a variety of data. If the former case, as in the sample code you posted, then these should probably have separate tests anyway, so that you can easily see that both INVERT_X and INVERT_BOTH are failing, but INVERT_Y is not, which may be valuable diagnostic data. On the other hand, if your test is trying the INVERT_X behavior on nine different points, you probably don't need or want to see every individual point that fails. It's enough to know that INVERT_X is failing and to have a sample point where it fails. In that case I would say just run them in a loop and don't worry that it might exit early. Also, I'd rather construct the error message from the data instead of maintaining it in different places, because manually keeping those in sync is another, errorprone burden. I'm not sure I follow the problem you're describing. If the factored out workhorse function receives the data to test, what prevents it from constructing an error message from that data?

Need advices regarding the strings (str, unicode, coding) used as interface for an external library.
I'm planning to build an external lib. This lib will exchange a lot of strings between the lib and the core Python code of applications. I wish this lib to be modern, 100% unicode compliant. It will be developped for Python 2.7 and for Python 3. In an early phase, technically, it will be developed on Python 2.7 before Python 3, probably 3.2. Two options for the strings interface. a) Pure unicode, that means only type 'unicode' in Python 2.7 and only type 'str' in Python 3. Similar to the Python io module. b) Like a) plus ascii and utf-8 encoded type 'str' to keep some kind of retro compatibility. This lib will anyway work in a unicode mode, so the ascii and the encoded utf-8 str's have to be converted into unicode. I'm very comfortable with all this coding stuff and aware of the pros and cons of each solutions. My favourite solution is clearly on the a) side. Advices and comments are welcome.

os.walk() or os.path.walk() can be used.
You need to traverse the file system.
AFAIK there is no support for this.
Or python only:
--
#!/usr/bin/env python
import os, fnmatch
# generator:
def find_files(directory, pattern):
for root, dirs, files in os.walk(directory):
for basename in files:
if fnmatch.fnmatch(basename, pattern):
filename = os.path.join(root, basename)
yield filename
# process each file as it is found:
for filename in find_files('apps/name', '*.js'):
print 'found java source:', filename

[issue10483] http.server - what is executable on Windows
Martin v. Löwis mar...@v.loewis.de added the comment: Martin, that is an interesting viewpoint, and one I considered, but didn't state, because it seems much too restrictive. Most CGI programs are written in scripting languages, not compiled to .exe. So it seems the solution should allow for launching at least Perl and Python scripts, as well as .exe. Notice that it does support launching Python scripts. I disagree that Perl scripts need to be supported. The idea of CGI is really that programs get run by the web server, with the notion of programs clearly deviating from system to system. Window really doesn't support scripts (in the hash-bang sense), and it isn't the function of http.server to extend Windows here. At best, support for .bat files might be negotiable, using cmd.exe to launch them (but I personally would not). Anybody who wants support for other kinds of scripts on Windows will have to subclass CGIHTTPRequestHandler (and it might be useful to simplify subclassing that class). In any case, the bug as stated (def executable is simply wrong) has a clear resolution - make it match what the rest of the code supports.

Though I am aware there are not many such systems to begin with, I am pretty certain they do exist (think: servers at an University giving Python access to students, and not using *nix for some reason). There are also non-multi-user systems with multiple accounts (think: production systems running stuff on different accounts), and this issue can be abused as one of many steps during an attack, after gaining shell access, but before gaining administrative rights. I acknowledge your right to choose not to fix this issue due to usability issues, but in such case imo there should be an explicit message during the installation making the user aware of this insecurity. The last months revealed issues like this in many applications and tools, and they have (mostly) been patched, so administrators might assume this was also fixed in Python (especially since this is known from 2005). -- nosy: +Gynvael.Coldwind ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1284316 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10483] http.server - what is executable on Windows
Glenn Linderman v+pyt...@g.nevcal.com added the comment: The rest of the code has clearly never had its deficiencies exposed on Windows, simply because executable() has prevented that. So what the rest of the code already supports is basically nothing. Reasonable Windows support is appropriate to implement as part of the bugfix. You state that it isn't the function of http.server to extend Windows, however, even MS IIS has extended Windows to provide reasonable web scripting functionality, albeit it its own way, thus convicting the Windows facilities of being insufficient. Attempting to use http.server to get a web testing environment running so that Python scripts can be tested locally requires some way of using an existing environment (except, of course, for all new web sites). I suppose you would claim that using http.server for a web testing environment is an inappropriate use of http.server, also. Yet http.server on Unix appears to provide an adequate web testing environment: yes, some of that is because of Unix's #! feature. This would certainly not be the first case where more code is required on Windows than Unix to implement reasonable functionality. My desire for support for Perl is not an attempt to convince Python developers to use Perl instead of Python, but simply a reflection of the practicality of life: There are a lot of Perl CGI scripts used for pieces of Web servers. Reinventing them in Python may be fun, but can be more time consuming than projects may have the luxury to do. Your claim that it already supports Python CGI scripts must be tempered by the documentation claim that it provides altered semantics. altered semantics, as best as I can read in the code, is that the query string is passed to the Python script as a command line if it doesn't happen to contain an = sign. This is weird, unlikely to be found in a real web server, and hence somewhat useless for use as a test server also. http.server has chosen to use subprocess which has chosen to use CreateProcess as its way of executing CGI. There are other Windows facilities for executing programs, such as ShellExecute, but of course it takes the opposite tack: it can execute nearly any file, via registry-based associations. Neither of these seem to be directly appropriate for use by http.server, the former being too restrictive without enhancements, the latter being too liberal in executing too many file types, although the requirement that CGI scripts live in specific directories may sufficiently rein in that liberality. However, you have made me think through the process: it seems that an appropriate technique for Windows is to allow for a specific set of file extensions, and permit them to be executed using the registry-based association to do so. However, for .cgi files, which depend heavily on the Unix #!, emulation of #! seems appropriate (and Windows doesn't seem to have an association for .cgi files either). Your suggestion of making CGIHTTPRequestHandler easier to subclass is certainly a good one, and is almost imperative to implement to fix this bug in a useful manner without implementing an insufficient set of Windows extensions (for someone's definition of wrong). There should be a way to sidestep the altered semantics for Python scripts (and Python scripts shouldn't have to be a special case, they should work with the general case), without replacing the whole run_cgi() function. There should be a hook to define the list of executable extensions, and how to run them, and/or a hook to alter the command line passed to subprocess.Popen to achieve same. So is_executable and is_python both seem to currently be replacable. What is missing is a hook to implement cmdline creation before calling subprocess.Popen() (besides the other reported bugs, of course) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10483 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

My job as a maintainer is to resolve this, and I will decide to resolve this as suggested. Even the refactoring to allow substitution of process creation is an independent feature, but I'm willing to accept patches. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10483 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I would not be at all surprised if my patch could be simplified (in fact
I'd be surprised if it couldn't).
However, I did try out your version on Python 2.5 specifically, and it
did not work for me.
Trying it out on help(Exception), the relevant members of
object.__subclasses__() viz.
type 'exceptions.StandardError', type 'exceptions.StopIteration' etc.
had a __module__attribute which equalled 'exceptions', not 'builtins'.

[issue10466] locale.py resetlocale throws exception on Windows (getdefaultlocale returns value not usable in setlocale)
Marc-Andre Lemburg m...@egenix.com added the comment: I think that's a bug in the resetlocale() API. The correct way to reset the locale setting to defaults, it to use setlocale(category, ) The other issues here is that getlocale() appears to return non-ISO language codes on Windows. If that's indeed the case, then we would need to add mappings of the Windows codes to the ISO ones and use a reverse mappings to make setlocale() work with the ISO codes. Perhaps it's easier to just update the mapping used by getdefaultencoding() to return the non-ISO codes used by Windows and then update the documentation to say that on Windows, non-ISO codes are returned.
