[issue15991] BaseHTTPServer with ThreadingMixIn serving wrong data sometimes

2012-10-10 Thread Charles-François Natali

Charles-François Natali added the comment:

According to http://tools.ietf.org/html/rfc2616#section-8.1,
persistent connections are default in HTTP 1.1.
However, here's what's said about the persistence negotiation:

   An HTTP/1.1 server MAY assume that a HTTP/1.1 client intends to
   maintain a persistent connection unless a Connection header including
   the connection-token close was sent in the request. If the server
   chooses to close the connection immediately after sending the
   response, it SHOULD send a Connection header including the
   connection-token close.

   An HTTP/1.1 client MAY expect a connection to remain open, but would
   decide to keep it open based on whether the response from a server
   contains a Connection header with the connection-token close. In case
   the client does not want to maintain a connection for more than that
   request, it SHOULD send a Connection header including the
   connection-token close.

   If either the client or the server sends the close token in the
   Connection header, that request becomes the last one for the
   connection.


And if you have a look at the strace output (or a tcpdump capture),
you see that httpserver indeeds sends a Connection: close header,
which wget ignores:

select(6, [5], NULL, NULL, {900, 0})= 1 (in [5], left {900, 0})
recvfrom(5, Connection: close\r\n, 390, MSG_PEEK, NULL, NULL) = 19
read(5, Connection: close\r\n, 19)= 19
select(6, [5], NULL, NULL, {900, 0})= 1 (in [5], left {900, 0})
recvfrom(5, \r\n, 371, MSG_PEEK, NULL, NULL) = 2
read(5, \r\n, 2)  = 2
select(6, [5], NULL, NULL, {0, 1})  = 0 (Timeout)
select(6, NULL, [5], NULL, {900, 0})= 1 (out [5], left {900, 0})
write(5, GET /FOUND-8154 HTTP/1.1\r\nUser-A..., 124) = 124
select(6, [5], NULL, NULL, {900, 0})= 1 (in [5], left {900, 0})
recvfrom(5, head\ntitleError response/ti..., 511, MSG_PEEK,
NULL, NULL) = 190
stat(FOUND-8154, 0x7fffcc530d60)  = -1 ENOENT (No such file or directory)
open(FOUND-8154, O_WRONLY|O_CREAT|O_TRUNC, 0666) = 7
clock_gettime(CLOCK_MONOTONIC, {130079, 24215187}) = 0
select(6, [5], NULL, NULL, {900, 0})= 1 (in [5], left {900, 0})
read(5, head\ntitleError response/ti..., 8192) = 190
clock_gettime(CLOCK_MONOTONIC, {130079, 24258187}) = 0
fstat(7, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0x2b0004bbc000
write(7, head\ntitleError response/ti..., 190) = 190
write(4, \n 0K..., 777) = 777
select(6, [5], NULL, NULL, {900, 0})= 1 (in [5], left {900, 0})
read(5, 0x1becc8f0, 8192)   = -1 ECONNRESET (Connection
reset by peer)
close(5)= 0


So it really looks like a wget bug.
I'd suggest closing as invalid, and reporting this to wget developers.

2012-10-10 Thread Antoine Pitrou

Antoine Pitrou added the comment:

Furthermore, BaseHTTPServer responds with a HTTP/1.0 status line (not 
HTTP/1.1), meaning persistent connections are not the default.

Therefore, I'm closing as invalid.

[issue16183] ZipExtFile object close without file handle closed

2012-10-10 Thread V.E.O

New submission from V.E.O:

Hi, I tried to open file-like object ZipExtFile in one zip file, after 
operations, I close it and after all, close ZipFile.
But I still can not remove the zip file immediately.

This problem happens on Windows, error msg:
WindowsError: [Error 32] The process cannot access the file because it is being 
used by another process: ..

Sample code as below:

z = ZipFile('D:\\1', 'r')
zlist = z.infolist()
for zi in zlist:
zf = z.open(zi)
zf.close()

z.close()
os.remove(attach)

[issue16114] incorrect path in subprocess.Popen() FileNotFoundError message

2012-10-10 Thread Gregory P. Smith

Gregory P. Smith added the comment:

replacing repr(args[0]) with repr(executable) in the identified python should 
be sufficient for this bug as originally reported.

BUT it goes deeper:  I just ran into this error in a different case.  It also 
happens when cwd is passed and the chdir(cwd) fails in the child process.  
args[0] is reported as not found rather than cwd in the error message.

I have a test and fix for that.  I'll take care of both.

[issue15278] UnicodeDecodeError when readline in codecs.py

2012-10-10 Thread Walter Dörwald

Walter Dörwald added the comment:

  codecs.utf_8_decode('\u20ac'.encode('utf8')[:2])
 ('', 0)

 Oh... codecs.CODEC_decode are incremental decoders? I misunderstood completly 
 this.

No, those function are not decoders, they're just helper functions used to 
implement the real incremental decoders. That's why they're undocumented.

Whether codecs.utf_8_decode() returns partial results or raises an exception 
depends on the final argument::

 s = '\u20ac'.encode('utf8')[:2]
 codecs.utf_8_decode(s, 'strict')
('', 0)
 codecs.utf_8_decode(s, 'strict', False)
('', 0)
 codecs.utf_8_decode(s, 'strict', True)
Traceback (most recent call last):
  File stdin, line 1, in module
UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 0-1: 
unexpected end of data

If you look at encodings/utf_8.py you see that the stateless decoder call 
codecs.utf_8_decode() with final==True::

def decode(input, errors='strict'):
return codecs.utf_8_decode(input, errors, True)

so the stateless decoder *will* raise exceptions for partial results. The 
incremental decoder simply passed on the final argument given to its encode() 
method.

[issue16179] hashlib.md5 / json inconsistency

2012-10-10 Thread Hynek Schlawack

Hynek Schlawack added the comment:

Actually, that’s not the point here, the code has a deeper flaw.

You’re computing hashlib.md5() on `data.encode()` and `str(jsonData).encode()`. 
Did you have a look how they look like?

 data.encode()
b'{key1:value1,key2:value2}'
[71875 refs]
 str(jsonData).encode()
b{'key1': 'value1', 'key2': 'value2'}

`str(jsonData)` doesn’t return JSON because it’s a simple dict():

 type(jsonData)
class 'dict'

If you wanted to have JSON again, you’d have to use `json.dumps()`:

 json.dumps(jsonData)
'{key1: value1, key2: value2}'

HOWEVER: This string _also_ differs from yours due to additional whitespace, 
ie. the sum would differ again.

Additionally, as David pointed out, you can’t rely on the order of the dict. 
json.dump() could just as well return `'{key2: value2, key1: value1}'`.

Chris Jerdonek added the comment:

Yes, almost.  The executable variable is a bytes object so it needs to be 
fsdecoded first.

 I have a test and fix for that.  I'll take care of both.

Let me at least upload what I already prepared.  You can add to it or modify it

[issue16184] Attack against the pseudorandom number generator

2012-10-10 Thread Yury

New submission from Yury:

---[ Vulnerability description]

Positive Research experts have detected a vulnerability Predictable 
pseudorandom numbers in Python caused by random.random() output in Python.

By default, Mersenne Twister initialization is done during random module import 
and then after 312 random.random() calls that allows attackers to predict 313 
random number with 2^8 accuracy based on 1, 2, 199, 200, 511, 625 random 
numbers.

--[Solution]
 
We recommend you to initialize random.seed() after every 312 calls that 
guarantees enough entropy of Mersenne Twister element statuses.

---[Credits]

Vulnerability was detected by Timur Yunusov, Positive Research Center (Positive 
Technologies Company)

---

1. In spite of the fact that MT states are initialized correctly, there is a 
practical method to exploit the vulnerability because of Python web framework 
peculiarities.
2. The possibility that a random number is among described 256 variants is 
12,5% because there are two methods to round off numbers to the certain 
accuracy. This provides 8 possible variants of existing state_1[2], 
state_1[397], state_2[397].
You can find the code necessary to demonstrate the vulnerability (vuln.py) and 
exploit it (brute.py) attached.

Chris Jerdonek added the comment:

I made some comments on the changes as committed here:

http://mail.python.org/pipermail/python-dev/2012-October/122125.html


It would be cleaner to use the self.assertRaises() pattern here and
also probably better to share code across the three test methods which
are nearly identical to one another (there is a fourth scenario I
would also add of shell=True).

I would also check for FileNotFoundError instead of OSError in the 3.3
and later versions.

[issue16184] Attack against the pseudorandom number generator

2012-10-10 Thread Christian Heimes

Christian Heimes added the comment:

I don't see a problem here. It's a well known and documented fact that a PRNG 
like a Mersenne-Twister must not be used for any cryptographic purpose. The 
most of the random module is designed to be deterministic. The global instance 
even keeps its state after fork(). It's really not a security issue but a 
feature.

http://docs.python.org/library/random.html
---
The Mersenne Twister is one of the most extensively tested random number 
generators in existence. However, being completely deterministic, it is not 
suitable for all purposes, and is completely unsuitable for cryptographic 
purposes.
---

The os.urandom() function and random.SystemRandom class are desigend to create 
cryptographically strong random data that can be for most purposes except for 
long lived crypto keys like SSL certs.

[issue16185] include path in subprocess.Popen() file not found error messages on Windows

New submission from Chris Jerdonek:

Currently, when subprocess.Popen() raises a FileNotFoundError on POSIX systems, 
the error message helpfully includes the path not found.  But it does not do so 
on Windows.

This issue is to include the path also in the messages of the corresponding 
errors on Windows.

[issue16175] Add I/O Completion Ports wrapper

2012-10-10 Thread Richard Oudkerk

Richard Oudkerk added the comment:

Adding the IOCP functions to _winapi is straightforward -- see patch.  Note 
that there seems to be no way to unregister a handle from an IOCP.

Creating overlapped equivalents of socket.accept() and socket.connect() looks 
more complicated.  Perhaps that should be added to the socket module or left to 
pywin32.

[issue15111] Wrong ImportError message with importlib

2012-10-10 Thread Brett Cannon

Brett Cannon added the comment:

Here are two possible tests.

1) __import__('distutils', fromlist=['_i_do_not_exist']) should return distutils

2) Use a fake loader which executes some code which does nothing more than 
tries to import a non-existent module. The trick with this test is that the 
submodule must be found but a module that the submodule needs cannot be found 
by import itself (and simply not faked with an ImportError thanks to the 
_not_found hack and needing that attribute to propagate up to the submodule 
search).

And I think the failure stems from the lack of check against exc.name equaling 
the name of the module being imported (e.g. exc.name == 
distutils.msvc9compiler) since the winreg import is a failed module search as 
well.

I added the workaround to the last remaining example.  Nick was right before in

[issue12947] doctest directive examples in library/doctest.html lack the flags

2012-10-10 Thread Chris Jerdonek

Chris Jerdonek added the comment:

Thanks, Georg.  Can this new directive be applied to individual code blocks 
though (or be modified to do so)?

After a closer review (as mentioned in my comment above), it seems that the 
doctest directives should only be displayed in the code snippets that are 
illustrating the use of doctest directives (as opposed to, say, the snippets 
that are illustrating doctest options without using directives).

[issue16184] Attack against the pseudorandom number generator

2012-10-10 Thread Georg Brandl

Georg Brandl added the comment:

 1. In spite of the fact that MT states are initialized correctly,
 there is a practical method to exploit the vulnerability because of
 Python web framework peculiarities.

What does this mean exactly?  If it means that this predictability can
be used for attacks on web frameworks because they assume cryptographic
strength of random numbers, please report it to those frameworks' 
security channels, e.g. secur...@djangoproject.com.

[issue16188] Windows C Runtime Library Mismatch

2012-10-10 Thread rlinscheer

New submission from rlinscheer:

When installing python-2.7.3.amd64.msi or python-2.7.3.msi and selecting for 
single-user (as opposed to for all users), an incorrect version of the 
microsoft C runtime library (msvcr90.dll) seems to be placed into the top-level 
directory along side the python executable.  This results in the message:

The application has failed to start because its side-by-side configuration is 
incorrect. Please see the application event log or use the command-line 
sxstrace.exe tool for more detail.

The event log shows the error too:

Activation context generation failed for C:\python_rob_32\pythonw.exe.Error 
in manifest or policy file C:\python_rob_32\Microsoft.VC90.CRT.MANIFEST on 
line 4. Component identity found in manifest does not match the identity of the 
component requested. Reference is 
Microsoft.VC90.CRT,processorArchitecture=x86,publicKeyToken=1fc8b3b9a1e18e3b,type=win32,version=9.0.21022.8.
 Definition is 
Microsoft.VC90.CRT,processorArchitecture=x86,publicKeyToken=1fc8b3b9a1e18e3b,type=win32,version=9.0.30729.1.
 Please use sxstrace.exe for detailed diagnosis.

Running the sxstrace tool shows the following:

INFO: Parsing Manifest File C:\python_rob_32\Microsoft.VC90.CRT.MANIFEST.
INFO: Manifest Definition Identity is 
Microsoft.VC90.CRT,processorArchitecture=x86,publicKeyToken=1fc8b3b9a1e18e3b,type=win32,version=9.0.30729.1.
ERROR: Component identity found in manifest does not match the identity 
of the component requested. Reference is

Microsoft.VC90.CRT,processorArchitecture=x86,publicKeyToken=1fc8b3b9a1e18e3b,type=win32,version=9.0.30729.1.
ERROR: Activation Context generation failed.

This would seem to be the relevant section of the trace, though I have attached 
the full output of the sxstrace if desired.

This leads me to the conclusion that a newer version of the C runtime library 
is being shipped with the python executable that was built with an older 
version.

This problem was mentioned with less detail in issue 14608, but closed without 
resolution as far as I can tell.

[issue12947] doctest directive examples in library/doctest.html lack the flags

2012-10-10 Thread Chris Jerdonek

Chris Jerdonek added the comment:

Like these that discuss the behavior of the doctest.IGNORE_EXCEPTION_DETAIL 
option (but before doctest directives have been introduced):

http://hg.python.org/cpython/file/0d6910bef979/Doc/library/doctest.rst#l543

The key is that you can have options take effect without using directives, so 
it would be good if people can see examples like that.

As currently written, they don't help them pass if doctest were run on the .rst

[issue16190] Misleading warning in random module docs

2012-10-10 Thread Christian Heimes

New submission from Christian Heimes:

The documentation [1] of the random module contains a misleading warning 

---
Warning: The generators of the random module should not be used for security 
purposes. Use ssl.RAND_bytes() if you require a cryptographically secure 
pseudorandom number generator.
---

The warning should point users to os.urandom() and random.SystemRandom rather 
than ssl.RAND_bytes(). On Linux os.urandom() wraps /dev/urandom [2], on Windows 
it uses CryptGenRandom() [3]. Both are suitable for most cryptographic purposes 
except for long-lived keys (SSL, SSH, GPG certs etc.). ssl.RAND_bytes() should 
only be used for such long-lived data and not for salts, session ids and 
similar.

I like to see the warning box in Python 2.7, too. It's still the default for 
docs.python.org. My inquiry is motivated by #16184.

Yes, and triggering a failure other than a permission error (which is

I compared performances of the two methods: dummy loop vs find. Results with a 
string of 100,000 characters:

 * Replace 100% (rewrite all characters): find is 12.5x slower than a loop
 * Replace 50%: find is 3.3x slower
 * Replace only 2 characters (0.001%): find is 10.4x faster

In practice, I bet that the most common case is to replace only a few 
characters. Replace all characters is a rare usecase.

Use attached unicode.patch on Python 3.4 with the following commands to 
reproduce my benchmark:

python -m timeit -s a='a'; b='b'; text=a*10 text.replace(a, b)
python -m timeit -s a='a'; b='b'; text=(a+' ')*(10//2) text.replace(a, 
b)
python -m timeit -s a='a'; b='b'; text=a+' '*10+a text.replace(a, b)

--

An option is to use the find method, and then switch to the dummy loop method 
if there are too much characters to replace. I don't know if it's necessary to 
develop such complex algorithm. It would be better to have a benchmark 
extracted from a real world application like a template engine.

[issue16076] xml.etree.ElementTree.Element is no longer pickleable

2012-10-10 Thread Santoso Wijaya

Santoso Wijaya added the comment:

This is because, in Python 3.3, xml.etree.ElementTree.Element is overridden by 
the C accelerator version, _elementtree.Element.

If you remove the statement, 

1708from _elementtree import *

the behavior from Python 3.2 comes back.

[issue16192] ctypes - documentation example

2012-10-10 Thread Brian Thorne

New submission from Brian Thorne:

The Python docs for ctypes have embedded examples including:

 c_int()
c_long(0)

But on my machine I get the (more expected?):

 c_int()
c_int(0)

Perhaps if some machines expect otherwise that should be documented, otherwise 
might we change them.

I looked at

and the examples with directives looked fine to me, with directive, syntax 
markup, and 'hide prompt' box. I also checked the next section and saw the one 
example that needed to have the directive visible. Really nice.

[issue16193] display full e-mail name in hg.python.org annotate pages

New submission from Chris Jerdonek:

This issue is to configure hg.python.org to display the full e-mail name on the 
annotate pages.  Currently, instead of displaying everything before the @ 
symbol, the pages display only the portion of e-mail addresses up to the first 
. or @, for example tim@19837.

Information on how to configure hgweb this way is here:
