Safe eval of insecure strings containing Python data structures?

'my_atom' : 1.20,
'my_dict' : { 2:50 , 'hi':'mom'},

# I would like to do something like this:
empty_space = {'__builtins__' : {}}
try:
config = eval(open(config.txt).read(), empty_space, empty_space)
except:
config = {}
print config
# But I know for certain that the above approach is NOT secure since

So is there an equally convenient yet secure alternative available for

Could anyone help me with that? Being dynamically typed, Python has no notion of variables having types, so the object isn't being passed as a generic object, you're getting what really is a generic object value of type NoneType, which means the value of traV is indeed None, not vec3(). class vec3: def __init__(self, x_ = 0.0, y_ = 0.0, z_ = 0.0): self.x = x_ self.y = y_ self.z = z_ class mat4: def translation( traV = vec3() ): tranM.rowLst[index][0] = traV.x AttributeError: 'NoneType' object has no attribute 'x' This code is perfectly fine. See below. Could anyone help me how to turn the traV as type of vec3() instead of NoneType object? That's not what's happening. It's not like traV is being cast to NoneType thus making x inaccessible, as that's not even possible to express in Python. What's happening is something is calling translation() with None as an argument, and of course None (the value the caller provided for traV) has no attribute 'x', hence the error. So, check the full exception traceback and see who's calling translation() and how the argument being passed to it got to be None.

Assuming the data structures are sufficiently basic, i.e. no class
instanciations, you can just use the json (AKA simplejson) library to
deserialize the data in the string. Python and JSON conveniently
happen to share the same syntax for literals (except for booleans
IIRC).
Also, if this is your program's config file, you might consider
changing it to INI-format and using ConfigParser
(http://www.python.org/doc/2.5.2/lib/module-ConfigParser.html)
instead.

wxPython binaries for Python 2.6
Hi All, A set of wxPython binaries for Python 2.6 on Win32, Win64 and Mac OS X are now available at http://wxpython.org/download.php What is wxPython? - wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit and 64-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2, and Mac OS X 10.4+. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters?

It does not expect input from stdin. However, this does not affect

I don't think it's a Python problem, but something related to java and how
it handles stdin/stdout. Try with another program.
But, my question now is, WHY is this an issue? If the launched
process doesn't read from its stdin, why would it block?
Several reasons - the child process might send enough text to stderr to
fill its buffer, and if the parent process doesn't read from the other end
of the pipe, the child blocks. That's why I suggested to use communicate
instead of stdout.read() - it takes care of such cases.
The only thing I can think of is that the JVM's stdout is tied to the
shell script's stdout, because that's the only way it can remain open
upon the termination of the child process. I suppose, at this point,
the next place to look is in shell script syntax to find out how to
detach the JVM from the script's process group.
Can't you redirect to a file instead?

inspect feature
Hello,
The 'inspect' module has this method:
inspect.getargvalues(frame)
It takes a frame and returns the parameters used to call it, including
the locals as defined in the frame, as shown.
def f( a, b, d= None, *c, **e ):
... import inspect
... return inspect.getargvalues( inspect.currentframe() )
...
f( 0, 1, 'abc', 'def', ( 3, 2 ), h= 'ghi' )
(['a', 'b', 'd'], 'c', 'e', {'a': 0, 'c': ('def', (3, 2)), 'b': 1,
'e': {'h': 'g
hi'}, 'd': 'abc', 'inspect': module 'inspect' from 'C:\Programs
\Python26\lib\in
spect.pyc'})
However, if you wanted a decorator that examines the parameters to a
function, you're out of luck. By the time you have a frame, you're
already in the function.
Perhaps it would not be as common as something like 'join' for
example, or even the rest of the functions in 'inspect', but do you
think something similar to 'getargvalues' that accepted a function and
an argument list, and returned a dictionary mapping parameters to
values, could be useful?

Re: how to get the thighest bit position in big integers?
greg wrote: Terry Reedy wrote: str.find is an historical anomaly that should not be copied. It was(is?) a wrapper for C's string find function. C routinely uses -1 to mean None for functions statically typed to return ints. The Python version logically should return None and usually does for other functions. I consider str.find to be an anomaly in two senses. First, it is the only function/method I can think of that directly duplicates another function/method by replace raising an exception with returning an error indicator. Some developers wanted to drop it from 3.0, and I too wish it had been. We get along fine without list.find and a whole slew of other such duplicates that one could think of. Second, it is the only function/method I can think of that follows the Unix/C convention of using '-1' as an error/exception/no-can-do indicator. When it is so used, it is not really an int, but an error indication represented as an int because there is no other choice. In Python, there is another choice -- None -- which is used routinely, including its use as the default return when there is nothing else to return. Although Guido has defended it on the grounds that it can be inconvenient having a function that returns different types under different circumstances. Also it discourages making the mistake of treating the return value as a boolean. I consider this backwards. Since -1 is a legal index in Python (unlike some other languages) as well as a legal int, returning -1 allows if not encourages the mistake of treating the fake return value as if it were a real value. Returning None would completely prevent any use of the error indicator other than to test it, which is the only thing one should be able to do with it. It should not be usable as an index or number in further calculations. I consider it a principle that error indicators that are returned rather than raised should be an illegal-to-use value if not a different type. As for convenience, if s.find(t) is None: is as easily to write (and clearer to read) as if s.find(t) == -1:. As far as I can see, different return types are only an issue, if at all, if values of both types are to be used in further calculations.

Hmm abspath should be able to be called with str or unicode of arbitrary lengths. Consumers of it shouldn't have to be concerned with the platform implementation when it can be smoothed over by the module.

indentation level (I prefer if (...) return; instead of if (...) {
very long block; }).
Changes in version 5:
- rename 'namebuf' buffer to 'buf', it's used for the filename and to
display the indentation space (strcpy(buf, ' ');).
- move Py_DECREF(fob); at the end of the GetLine loop
- return on lineobj error

[issue4055] Documentation on website is missing section numbers
Georg Brandl [EMAIL PROTECTED] added the comment: I disagree that missing section numbers are a severe usability hit. Especially in the context that the new docs are constantly updated, there's no telling when section numbers will shift, misleading those who only navigate by section number. In contrast, a link is persistent and usually also quicker to get to. That said, I acknowledge the wish for section numbers, and there is an issue entry about it in the tracker for the Sphinx project, which is used to build the new docs, at http://code.google.com/p/sphinx.

[issue4078] asyncore fixes are not backwards compatible
New submission from Sidnei da Silva [EMAIL PROTECTED]: I am working on getting Zope to run (or at least, start) with Python 2.6. It actually starts right now after applying some patches, which is amazing on itself, but it dies right away due to changes in asyncore that break Zope's internal version of medusa. I've opened a bug against Zope on Launchpad, but someone suggested that it might actually be a bug in python, in the sense that it changed asyncore in a backwards-incompatible way. I wouldn't go that far, since I think it's more likely that Zope's version of medusa is poking into asyncore internals instead. Here's the bug, for reference: https://bugs.launchpad.net/zope2/+bug/280020 I suspect a change similar to this will need to be applied to medusa: http://codereview.appspot.com/744/diff/1/23 I'm puzzled though as to why the change is incompatible. I would have expected at least some kind of deprecation warning on Python 2.5. Either way, if you think the issue needs to be fixed in medusa feel free to close this bug. -- components: Library (Lib) messages: 74540 nosy: sidnei severity: normal status: open title: asyncore fixes are not backwards compatible type: behavior versions: Python 2.6 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4078 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4079] new urllib2.Request 'timeout' attribute needs to have a default
New submission from Sidnei da Silva [EMAIL PROTECTED]: 'urllib2' has introduced a configurable 'timeout' setting by assigning to the 'timeout' attribute of the urllib2.Request object. However the implementation is flawed: - the 'timeout' attribute is set in OpenerDirector.open() and nowhere else - if someone overrides OpenerDirector.open() (btw: mechanize does this), then the 'timeout' attribute will never be set, breaking other parts of the code which require the 'timeout' attribute to be present. A simple workaround for this would be to do one or more of: a) define the 'timeout' attribute as socket._GLOBAL_DEFAULT_TIMEOUT at class-level b) initialize the 'timeout' attribute on urllib2.Request.__init__() -- components: Library (Lib) messages: 74541 nosy: sidnei severity: normal status: open title: new urllib2.Request 'timeout' attribute needs to have a default type: behavior versions: Python 2.6 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4079 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue4075] Use WCHAR variant of OutputDebugString
Martin v. Löwis [EMAIL PROTECTED] added the comment: I agree that a static buffer should be used. I think calling it in a loop is overkill.

I could find only a single caller that doesn't pass a static string (_Py_NegativeRefcount), where I think 50 characters are still plenty. -- nosy: +loewis ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4075 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4017] IDLE 2.6 broken on OSX (Leopard)
Leo M [EMAIL PROTECTED] added the comment: Hello. First time here, beginner at Python. I have verified that the Google tip link in the previous to fix IDLE works for me. Post in question: ** [Kevin's post of 6.Oct, 02:58] You can avoid this problem by building Python yourself and putting /Library/Frameworks first on the search path for Tcl/Tk. Look in setup.py in the source code, around line 1438 (in the 'detect_tkinter_darwin' function), and either comment out /System/Library or put it underneath /Library/Frameworks. This is what the official build from Python.org should do--look first in /Library/Frameworks and then fall back on /System/Library/Frameworks. I'm not sure why it doesn't. ** In setup.py, I simply put /Library/Frameworks/ first as outlined above, and then did a config-make-install of the Framework version of Python.

Jason Day [EMAIL PROTECTED] added the comment: Indeed. Do you happen to have the complete traceback of the failing tempfile.mktemp() call? I don't see where it can use the PATH environment variable. The problem was that somehow, on our systems, the TEMP environmental variable had been copied over with PATH. Most likely some batch file tried to store a copy of PATH, without realizing the significance of TEMP. [groan] Anyway, I still think that it's a bug that abspath() can't be called with a perfectly good str path, because of limitations with the windows api. I edited the bug title to reflect the actual bug. The str path length could be checked and upgraded to the Unicode version, if necessary (or try again with the unicode version, in the case of an exception). I think it's important to ensure that when abspath() is called with str, it returns str, even if it was upgraded to the unicode call. -- title: ntpath.abspath fails for long str paths - ntpath.abspath can fail on Win Server 2008 (64-bit) ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4071 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue3994] import fixer misses some symbols
Nick Edds [EMAIL PROTECTED] added the comment: The problem is that fix_imports doesn't look at matches that are nested within matches. So the _winreg.OpenKey part gets fixed, but the _winreg.HKEY_LOCAL_MACHINE does not because it is nested within the other node. I didn't make fix_imports so I don't know what the intention was for not matching nested matches. When I removed that restriction, the fixer works as expected. It also does not cause any of 2to3's tests to fail nor does it have a noticeable impact on 2to3's runtime, so I'm tempted to say that this is the fix to make, but I don't want to commit to it until I've heard from it's author about it. I added Collin to the Nosy List, so hopefully he can comment on the reasoning behind the restriction. -- nosy: +collinwinter ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3994 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
