[issue10834] Python 2.7 x86 fails to run in Windows 7

2011-01-05 Thread Peter Heiberg


New submission from Peter Heiberg :

I recently installed Win7 on my laptop, and installed the x86 Python 2.7 
package.  IDLE fails to even start, and shows nothing but a process in task 
manager.  I've tried compatibility modes both to Vista and XPSP2, with no luck.

I ran 2.7 x86 on the same laptop in XPSP2, and I am also able to run 2.7 x86 on 
another computer using the exact same version of Win7.

Command line works fine, by the way.

[issue2193] Cookie Colon Name Bug

2011-01-05 Thread John J Lee


John J Lee  added the comment:

karl: I'm not clear precisely what it is that you want to draw our attention 
to.  Note this bug is about parsing of Cookie headers by servers, not 
production of Set-Cookie headers by servers.

Added Travis to nosy list - even if he doesn't have time to finish this off 
himself, hopefully he can point us in the right direction.

[issue4953] cgi module cannot handle POST with multipart/form-data in 3.0

2011-01-05 Thread R. David Murray


R. David Murray  added the comment:

Yeah, the documentation for the email stuff is in the dev docs.  There's a 
short summary in the changes section of the email intro with links to the 
classes and methods that are affected.  But basically you call BinaryFeedParser 
and feed it a binary data, and everything else works just like it did before, 
including the fact that get_payload() with no arguments returns a string.  If 
there is non-ASCII data in that string and no charset was specified the binary 
data will get trashed though.  To get the binary data out you call it with 
decode=True.

I believe you are right that the io module does not support intermixing calls 
to the main object and its buffer attribute; that's why detach was introduced, 
I believe.  Antoine is nosy on this issue now; he can correct me if I'm wrong.

So unfortunately I think we do need to come at this starting from binary at the 
beginning and *decoding* as needed (I believe http uses latin-1 when no charset 
is specified, but I need to double check that).  That still leaves the problem 
of what if anything to do about existing programs that expect every value in a 
FieldStorage to be a string.  Introduce a new method or parameter for getting 
the binary version of the value, possibly with some flag indicating that 
parsing detected non-ascii data?

[issue10835] sys.executable default and altinstall

2011-01-05 Thread Allan McRae


New submission from Allan McRae :

when sys.executable is run with a modified argv[0] such as:

> sh -c "exec -a '' /usr/bin/python2.7 -c 'import sys; print(sys.executable)'"

it returns some a hardcoded value.   In this case, it returns /usr/bin/python.  
 This value is likely wrong when python is installed with "make altinstall".

A possible solution is to modify the "progname" variable in Python/pythonrun.c 
to include the version in it so that the hardcoded return value is the most 
version specific binary.  I.e.

static char *progname = "python2.7";

[issue8033] sqlite: broken long integer handling for arguments to user-defined functions

2011-01-05 Thread Amaury Forgeot d'Arc


Amaury Forgeot d'Arc  added the comment:

- unit tests are needed.
- Py_LONG_LONG should be used instead of "long long", and the cast removed.
- The patch assumes that longlong == int64, but is it true on all platforms?

[issue10833] Replace %.100s by %s in PyErr_Format(): the arbitrary limit of 500 bytes is outdated

2011-01-05 Thread Eric Smith


Eric Smith  added the comment:

I always thought that one of the reasons for specifying the length was in case 
a pointer pointed to garbage: at least you'd be limiting how much trash was 
printed. But maybe that's just my imagination and there is no such reason.

[issue2193] Cookie Colon Name Bug

2011-01-05 Thread karl

karl added the comment:

John: Ah sorry, if I misunderstood. The bug seems to say that it is about the
Cookie Name and legal chars for this cookie name. What I was trying to say is
that the processing of the Cookie Name is different depending if you are a
client or a server *and* that there is a specification being developed by Adam
Barth (part of browser vendors) to obsolete RFC 2109.

In the case of Server sending to the Client
Set-Cookie: Name=Value

The rules for production of the cookies must be strict. Always. aka the module
is used for creating a cookie and indeed the "colon" character is forbidden.
The "token" syntax for valid chars and invalid chars are defined now in
RFC2696. It means that any US-ASCII characters EXCEPT those are authorized:

control characters (octets 0-31) and DEL (octet 127) and, the following
characters “(“, “)”, “<”, “>”, �...@”, “,”, “;”, “:”, “", “/”, “[“, “]”, “?”,
“=”, “{“, “}”, the double quote character itself, US-ASCII SP (octet 32) or the
tabulation (octet 9)

Then if you use the Cookie Module for a client it is not anymore the same story.

In the case of Client storing the value of the cookie sent by a server.
See the section "5.2. The Set-Cookie Header",
http://tools.ietf.org/html/draft-ietf-httpstate-cookie-20#section-5.2

quote:

If the user agent does not ignore the Set-Cookie header
field in its entirety, the user agent MUST parse the
field-value of the Set-Cookie header field as a
set-cookie-string (defined below).

NOTE: The algorithm below is more permissive than the
grammar in Section 4.1. For example, the algorithm strips
leading and trailing whitespace from the cookie name and
value (but maintains internal whitespace), whereas the
grammar in Section 4.1 forbids whitespace in these
positions. User agents use this algorithm so as to
interoperate with servers that do not follow the
recommendations in Section 4."

/quote

then the algorithm is described. Which means that what the server will parse
will not be necessary what the server have generated.

Section 5.4 says how the Cookie Header should be sent to the server with an
algorithm for what will receive the server.

John, do you think there is a missing algorithm for parsing the value of cookie
header when sent by the client?

[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)

2011-01-05 Thread Mark Dickinson


Mark Dickinson  added the comment:

Nick, it sounds as though you have an idea of how you think things should be 
working here---perhaps you can help me out.  I'd really like to understand what 
the implementation should look like from the POV of a 3rd party module that 
defines some object exporting the buffer interface.

Here's a specific scenario I'd like to understand:  module foo defines a type 
Foo that implements the buffer protocol.  For simplicity, suppose it's 
exporting 1-dim buffers. When I do:

>>> from foo import Foo
>>> foo_object = Foo()
>>> m = memoryview(foo_object)
>>> n = m[::2]  # take a slice of m
>>> del m   # delete the objects, in whichever order.
>>> del n

what's the sequence of getbuffer and releasebuffer calls that foo_object should 
expect to see?

Q1. Does foo get 2 requests to getbuffer (and 2 to releasebuffer), or just one 
each?  I'm assuming at least that getbuffer and releasebuffer calls should be 
paired.

Q2. For each pair of getbuffer/releasebuffer calls, should the 'view' parameter 
passed into releasebuffer be identical to that provided to getbuffer?  Or is it 
acceptable for the actual Py_buffer* pointers to be distinct, but the 
pointed-to Py_buffers to be exact copies.  (The existence of the smalltable 
field complicates the notion of an exact copy a little bit, but I think that's 
a detail that can be ignored for these questions.)

[issue4489] shutil.rmtree is vulnerable to a symlink attack

2011-01-05 Thread Ross Lagerwall


Ross Lagerwall  added the comment:

Here is a draft patch.

It uses the *at functions and fdlistdir consequently it only makes it safe if 
those functions are available. It works using a recursive implementation and an 
open file descriptor pointing to a directory, instead of maintaining state by 
changing the current directory. If the *at functions are unavailable, it falls 
back to the unsafe implementation.

It requires the patches from issue4761 and issue10755 to work.

I’ve learned in a recent discussion on web-sig that you can mix them, provided 
that you call stream.flush() before using stream.buffer.

[issue2193] Cookie Colon Name Bug

2011-01-05 Thread John J Lee


John J Lee  added the comment:

Again, I don't think this is relevant, because the bug is about servers parsing 
Cookie: headers.  Note that that string (the value of the Cookie: header) may 
be generated by a different server than the server that parses it (see the trac 
example mentioned in the bug comments).
