Subject: [New-bugs-announce] [issue3020] doctest should have lib2to3
integration

Message-ID: <1212331047.91.0.677781535819.issue3020@psf.upfronthosting.co.za>
New submission from Stefan Behnel <scoder at users.sourceforge.net>:
Running a doctest with Py2 syntax in Py3 currently involves either
running the 2to3 tool by hand or writing code to convert the doctest
using lib2to3, and then running the modified version. This basically
pushes the burden of automating this step in any test runner script in
the world onto the authors or users of these scripts.
Writing portable code is hard enough, but writing portable doctests that
remain user readable should not remain as hard as it currently is. The
doctest module in Py3 should have a simple option to run a Py2 doctest
(in a file or doc string) without requiring users to write the glue code
for it.
On a related note, if a 3to2 tool becomes available, this should be
directly supported by doctest in Py2.6.

New submission from Antoine Pitrou <pitrou at free.fr>:
This patch implements the proposal outlined on the py3k mailing-list
here: http://mail.python.org/pipermail/python-3000/2008-May/013740.html
It solves both #2507 and #2833, and even improves re-raising semantics
in several cases (see the test cases which were added to test_raise.py).
Anothing thing worth noting is that f_exc_* fields are not accessible
from Python code anymore, because their semantics is an implementation
detail and shouldn't be relied upon.

New submission from Guilherme Polo <ggpolo at gmail.com>:
While fixing the tkinter demos, I found some problems when moving from
mhlib to mailbox that are corrected in the attached patch.
The first fix:
- for name, key_list in self.get_sequences():
+ for name, key_list in self.get_sequences().iteritems():
I'm not sure someone else used the module before, or at least
get_sequences() since it returns a dict and it just fails in the current
code.
The second fix is about the .mh_sequences file format I found here, it
may have some lines with one space, or two, after its content which was
causing the get_sequences() to fail too.

The error message has no newline at the end:
$ LANG=en_GB.UTF-8 python3.0 test.py $'\xff'
Could not convert argument 2 to string$
Seriously, though: is this the intended behaviour? If the
interpreter just dies when it gets a non-UTF-8 (or whatever)
argument, it creates an opportunity for a denial-of-service if
some admin is running a Python script via find(1) or similar.
And what if you want to run a Python script on some files named
in a mixture of charsets (because, say, you just untarred an
archive created in a foreign charset)?
Could sys.argv not provide bytes objects for those arguments,
like os.listdir()? Or (better IMHO) have a separate
sys.argv_bytes interface?

This issue is probably older than I am, and was amazed to discover it in
python:
Python 2.5.2 (r252:60911, May 7 2008, 15:19:09)
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
>>> int(float("-23.15"))
-23
>>> int(float("-23.65"))
-23
>>> int(float("24.9"))
24
>>> int(float("24.4"))
24
Is this by design? What is the python way of obtaining a correct result?

New submission from Jim Jewett <jimjjewett at users.sourceforge.net>:
The str->Unicode change widened IDLE/batch discrepancy.
In python 2.x, bytes are printable.
>>> for i in range(256): print i, chr(i)
works fine. In python 3, chr has become (the old) unichr, and whether a
unicode character is printable depends on the environment. In particular,
under my Windows XP, the equivalent
>>> for i in range(256): print (i, chr(i))
will still work fine under IDLE, but will now crash with an
UnicodeEncodeError when run from the command line.
----------------
Unfortunately, I'm not sure what the right solution actually is, other than
a mention in the Whats New document.
I believe the 2.5 code was using a system page to print those characters, as
they often looked like letters rather than <control>. Copying that would
probably be the wrong solution.
Limiting IDLE would add consistency, but might be a lot of work for the
equivalent of a --pedantic flag.
PEP 3138 seems to be proposing a default stdout BackslashReplace, which may
at least help.

New submission from Matthew Mueller <donut at users.sourceforge.net>:
mmap on large files on 64 bit platforms in python >=2.5 returns some
sort of garbage. In 2.4 it would just throw an exception. Now I get
something like this (script runs md5.md5 on mmap object, and then runs
os.system md5sum for comparison):
This is python2.5 from Ubuntu 8.04 AMD64
/tmp$ python2.5 testbigfile.py
python mmap md5: 1230552d39b7c1751f86bae5205ec0c8
abe59e28c9a3f11b883f62c80a3833a5 *bigfile
This is python svn as of 20080601, compiled the on same system.
/tmp$ python2.6 testbigfile.py
testbigfile.py:5: DeprecationWarning: the md5 module is deprecated; use
hashlib instead
import md5
python mmap md5: 1230552d39b7c1751f86bae5205ec0c8
abe59e28c9a3f11b883f62c80a3833a5 *bigfile
Also note how the python md5 call returns immediately, not something you
would expect when md5ing 4GB of data.

The c extend module is as the attached file "WindowsFuncs.cpp", it

The python script is as the attached file "test.py", run that script,
we could find in the new thread, the calling to Windows API
waitForSingleObject will block the main thread printing, that's really
strange.
The output of running is as the attached file "test.output".

New submission from Noam Raphael <noamraph at gmail.com>:
Hello,
The documentation of the tokenize module says: "The line passed is the
*logical* line; continuation lines are included."
Some background: The tokenize module splits a python source into tokens,
and says for each token where it begins and where it ends, in the format
of (row, offset). This note in the documentation made me think that
continuation lines are considered as one line, and made me break my head
how I should find the offset of the token in the original string. The
truth is that the row number is simply the index of the line as returned
by the readline function, and it's very simple to reconstruct the string
offset.
I suggest that this will be changed to something like "The line passed
is the index of the string returned by the readline function, plus 1.
That is, the first string returned is called line 1, the second is
called line 2, and so on."
Thanks,
Noam

New submission from fma <fma at gbiloba.org>:
For python2.4:
Python 2.4.4 (#2, Apr 15 2008, 23:43:20)
[GCC 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)] on linux2
The distutils documentation says to use an empty string in the
setup() 'package_dir' param. for current dir. It works fine for python
modules, but it fails when using 'package_data' param. For example:
.
|-- __init__.py
|-- module1.py
|-- module2.py
|-- setup.py
`-- view
|-- __init__.py
|-- module3.glade
|-- module3.py
|-- module4.glade
`-- module4.py
setup.py:
from distutils.core import setup
setup(name='my_package',
package_dir={'my_package': ''},
packages=['my_package', 'my_package.view'],
package_data={'my_package': ['view/*.glade']}
)
$ python setup.py build
running build
running build_py
creating build
creating build/lib
creating build/lib/my_package
copying module1.py -> build/lib/my_package
copying module2.py -> build/lib/my_package
copying __init__.py -> build/lib/my_package
creating build/lib/my_package/view
copying view/module3.py -> build/lib/my_package/view
copying view/module4.py -> build/lib/my_package/view
copying view/__init__.py -> build/lib/my_package/view
creating build/lib/my_package/iew
error: can't copy 'iew/module3.glade': doesn't exist or not a regular
file
To correct this, '.' should be used instead of the empty string:
from distutils.core import setup
setup(name='my_package',
package_dir={'my_package': '.'},
packages=['my_package', 'my_package.view'],
package_data={'my_package': ['view/*.glade']}
)
Note that the empty string works fine on python2.5:
Python 2.5.2 (r252:60911, Apr 17 2008, 13:15:05)

New submission from Nick Veitch <veryevilnick at googlemail.com>:
In the whatsnew/3.0.html doc, the example for print is the wrong way
around. Current version reads:
* The :func:`print` function doesn't support the "softspace" feature of
the old ``print`` statement. For example, in Python 2.x,
``print "A\n", "B"`` would write ``"A\nB\n"``; but in Python 3.0,
``print("A\n", "B")`` writes ``"A\n B\n"``.

tarfile.TarFileCompat.writestr(ZipInfo, str) raises AttributeError

Message-ID: <1212632567.86.0.457282985708.issue3039@psf.upfronthosting.co.za>
New submission from Jason Kankiewicz <jkankiewicz at acm.org>:
tarfile.TarFileCompat.writestr( self, zinfo, bytes ) raises
AttributeError("'ZipInfo' object has no attribute 'name'") because an
analog to the tarfile.TarInfo.name attribute cannot be monkeypatched
into the zinfo argument value when it's an instance of zipfile.ZipInfo.
The zipfile.ZipInfo class' attributes are slots, so no ad hoc attributes
can be monkeypatched into an instance of it.
I've replaced the monkeypatching of zinfo with the creation of a new
tarfile.TarInfo object, tinfo, which receives its relevant values instead.
This revealed another problem with the assignment of zinfo.file_size to
tinfo.size: if zinfo.file_size has not been assigned a value then an
AttributeError("file_size") will be raised because the slotted attribute
doesn't exist.
Being that the documentation for zipfile.ZipFile.writestr( self,
zinfo_or_arcname, bytes ) claims that a zipfile.ZipInfo object value for
zinfo_or_arcname must contain "at least the filename, date and time",
it's highly likely that zinfo.file_size will be unassigned in ordinary use.
I fixed this problem by ignoring the value of zinfo.file_size and using
the value of len(bytes) instead, just like the implementation of
zipfile.ZipFile.writestr.
I would have provided a patch for tarfile.TarFileCompat.writestr's unit
test suite, but it doesn't appear to exist.

New submission from Trevor Meyerowitz <trevor.meyerowitz at sun.com>:
There are two minor bugs in the example in:
http://docs.python.org/lib/optparse-callback-example-6.html
For the optparse example documentation, the call to parser.add_option is
listed as:
parser.add_option("-c", "--callback",
action="callback", callback=varargs)
this has two bugs:
1. It refers to the wrong function name
2. It needs to have a dest variable defined, b/c the callback function
operates on that.
This can be fixed if the parser.add_option call is changed to:
parser.add_option("-c", "--callback",
action="callback", dest="foo", callback=varargs_callback)

Message-ID: <1212670566.42.0.274403876451.issue3042@psf.upfronthosting.co.za>
New submission from Nick Coghlan <ncoghlan at gmail.com>:
PEP 371 highlighted the non-PEP 8 compliant nature of the threading API.
Since part of that PEP involves updating the multiprocessing API to be
PEP 8 compliant before addition the standard library, the threading API
should also be updated to be PEP 8 compliant in 3.0.
That part's easy - the trickier part if to provide both the existing API
and a PEP 8 compliant API in 2.6, with the old names triggering a
warning when run with the -3 switch, but not suffering a performance hit
otherwise.
The trick with that is to define the renamed API's differently depending
on whether or not sys.py3kwarning is set, rather than checking it every
time the old APIs are invoked.
(Left unassigned for the moment, since I'm about to go completely
offline for a few days, so it will be tough for me to get to this before
the first beta)

New submission from Tyler Laing <trinioler at gmail.com>:
With the following code:
class Vertex:
def __init__(self, type):
self.type = type
self.color=-1
self.edges=[]
class Edge:
def __init__(self, V1, V2):
self.vertexes=[V1, V2]
V1.edges.append(self)
V2.edges.append(self)
Where the references are cyclic(this is for a research project into
graph algorithms), and using deepcopy, even on a tiny graph of five
vertexes and 25 edges causes deepcopy to run into the recursion limit.
At the very least, it should warn it can't copy the indicated object, as
the references are cyclic. At the very most, it should be able to handle
complex cyclic references like this properly.

New submission from Peter Whaite <whaite at gmail.com>:
If the environ vars TEMP or TMP contain spaces on w32 the on-line help
will not work. e.g. help('or') gives the message
The system cannot find the file specified.
This is because pydoc.tempfilepager sets filename=tempfile.mktemp()
which will have spaces in it if TEMP does. The filename is then used to
constuct the system command:
os.system(cmd + ' ' + filename)
which in windows ends up as os.system('more < FILE WITH SPACES'). The
filename should be quoted, e.g.
os.system('%s "%s"' % (cmd,filename))
I only ran across this problem because I use uwin on windows and it sets
TEMP to a w32 style long path. The normal windows command shell uses
the dos spaceless sort form for the TMP and TEMP env vars so the problem
doesn't arise when python is invoked from there.
And isn't tempfile.mktemp() deprecated?

additional tickets will be created for issues which will need to be
addressed after initial inclusion.
Currently open:
- Redo all documentation to match ReST format of stdlib
- Update docs to reflect new PEP8 names
- Update all unit tests to be in Unittest format
Closed:
- Rename module API to be PEP8 compliant (roudkerk)
- Link csource libs into python-trunk build (jnoller)
- redo all local "." style imports to reflect the new namespace

Subject: [New-bugs-announce] [issue3051] heapq change breaking compatibility
In-Reply-To: <1212755858.43.0.854603033808.issue3051@psf.upfronthosting.co.za>
Message-ID: <1212755858.43.0.854603033808.issue3051@psf.upfronthosting.co.za>
New submission from Thomas Herve <therve at free.fr>:
A recent change in heapq implements it in terms of less-than:
http://svn.python.org/view/python/trunk/Modules/_heapqmodule.c?rev=63827&r1=63675&r2=63827
Unfortunately, it breaks usage of heapq when a class only implements
__le__ and not __ge__ or __cmp__. This is done this way in Twisted:
http://twistedmatrix.com/trac/browser/trunk/twisted/internet/base.py#L159.
If not mandatory, it would be nice if this change was reverted or that a
backward compatible change was done instead.

New submission from Antoine Pitrou <pitrou at free.fr>:
test_shutil fails with the following error under some AIX 5.3 machine:
======================================================================
FAIL: test_on_error (__main__.TestShutil)
----------------------------------------------------------------------
Traceback (most recent call last):
File "Lib/test/test_shutil.py", line 35, in test_on_error
shutil.rmtree(TESTFN, onerror=self.check_args_to_onerror)
File "/qakplus/qa_test/SandBoxes/Antoine/Python-2.5.2/Lib/shutil.py",
line 161, in rmtree

File "Lib/test/test_shutil.py", line 49, in check_args_to_onerror
self.assertEqual(func, os.remove)
AssertionError: <built-in function listdir> != <built-in function remove>
The problem seems to be that the system is stricter with permissions
(please note I don't know AIX at all, and the filesystems are unknown
brands of network filesystems :-)), and @test in that test case is set
to chmod 0400:
$ chmod 400 @test
$ ./python -c "import os; print os.listdir('@test')"
Traceback (most recent call last):
File "<string>", line 1, in <module>
OSError: [Errno 13] Permission denied: '@test'
$ chmod 100 @test
$ ./python -c "import os; print os.listdir('@test')"
Traceback (most recent call last):
File "<string>", line 1, in <module>
OSError: [Errno 13] Permission denied: '@test'
$ chmod 500 @test
$ ./python -c "import os; print os.listdir('@test')"
['a']
The error was witnessed with Python 2.5.2 but the test case doesn't seem
to have changed in trunk so it should be the same there too.

New submission from Ronald Oussoren <ronaldoussoren at mac.com>:
test_list, and possible other tests, use a lot of memory when Python is
build in 64-bit mode. This causes heavy swapping when the machine doesn't
have a huge amount of memory.
I've filed this bug because an OSX box with 3 GBytes of RAM gets
completely unresponsive when trying to run test_list (due to heavy
swapping).

Subject: [New-bugs-announce] [issue3058] Let SimpleXMLRPCServer pass
client_address to called functions.
In-Reply-To: <1212855971.92.0.424447915547.issue3058@psf.upfronthosting.co.za>
Message-ID: <1212855971.92.0.424447915547.issue3058@psf.upfronthosting.co.za>
New submission from Kunshan Wang <wks1986 at gmail.com>:
I recently wrote a program making use of SimpleXMLRPCServer.
It has a function that responds to the caller according to the caller's
IP address. However the current SimpleXMLRPCServer does not allow me to
do this (directly).
For example:
def whoami():
# blah blah blah ....
return the_caller_s_ip_address
svr.register_function(whoami)
The problem is that only SimpleXMLRPCRequestHandler knows the client's
IP address. I googled and searched the google group. Many people
recommends subclassing the SimpleXMLRPCRequestHandler. I did this, but
found that it is not very easy, although possible.
I managed to make the RequestHandler pass its member client_address to
function _dispatch by subclassing SimpleXMLRPCRequestHandler,
copy-and-paste the code from the library, and then add an extra argument
to _dispatch. Now _dispatch function looks like this:
_dispatch(self, method, params, client_address)
By default _dispatch assumes that the first parameter of 'method' is
client_address, and then followed by other parameters from the (remote)
caller. So if the XMLRPC client calls:
s=xmlrpclib.Server("http://localhost:9999")
s.whoami()
the server actually calls whoami(client_address), where whoami is
defined as:
def whoami(client_address):
return client_address
The attachment contains a subclassed version of SimpleXMLRPCServer,
named AddressRevealingXMLRPCServer. The code is ugly (because most
codes are copied, and is vulnerable to future library changes), but it
just works now.
However this leads to more problems: Now that client_address can be
passed to the called function, it may be needed that more informations
could be passed to the called function, such as the HTTP headers, the
response time, etc..
My code may not be the best solution.
I suggest there may be some mechanism (such as overridable methods) to
be added to SimpleXMLRPCServer so that user can specify *what* to pass
to the called function.

It decodes the system strftime's result using TZNAME_ENCODING which is
also used to decode timezone names. This may be correct for timezone
names themselves (I don't know), but the strftime result is encoded in
the LC_TIME encoding - at least on my Linux system.

When using the speed() function of the turtle module under Mac OS X,
it has no effect : the turtle always draws lines with the same speed.
An easy fix is to replace line 553 of the turtle.py file
by "sleep(self._delay / 1000.0)", however I don't know if it is the
best solution.

turtle3.zip contains the port of the new turtle module (including demo

(tdemo_forest.py)
It has been tested under Windows/MacOsX/Linux without showing up any
problems.
I've done a few small changes to the API - as proposed in issue 1513695
- which are described in the docfile.

There is currently a pickling bug in the namedtuple factory:
>>> from collections import namedtuple
>>> MemoRecord = namedtuple("MemoRecord", "key, msg")
>>> m = MemoRecord(1,"hello")
>>> import pickle
>>> pickle.loads(pickle.dumps(m))
Traceback (most recent call last):
...
TypeError: __new__() takes exactly 3 positional arguments (2 given)
The bug is due to the fact that classes created by namedtuple don't
handle the __new__ arguments in the same fashion as tuple.__new__. The
fix is simply to define __getnewargs__.

Message-ID: <1213009389.23.0.132424094421.issue3066@psf.upfronthosting.co.za>
New submission from Bohdan Vlasyuk <bohdan at google.com>:
In urllib2.AbstractHTTPHandler.do_open, the following like creates a
circular link:
r.recv = r.read
[r.read is a bound method, so it contains a reference to 'r'. Therefore,
r now refers to itself.]
If the GC is disabled or doesn't run often, this creates a FD leak.
How to reproduce:
import gc
import urllib2
u = urllib2.urlopen("http://google.com")
s = [ u.fp._sock.fp._sock ]
u.close()
del u
print gc.get_referrers(s[0])
[<socket._fileobject object at 0xf7d42c34>, [<socket object, fd=4,
family=2, type=1, protocol=6>]]
I would expect that only one reference to the socket would exist (the
"s" list itself).
I can reproduce with 2.4; the problems seems to still exist in SVN HEAD.

New submission from Arnaud Delobelle <arnodel at googlemail.com>:
The patch allows the following syntax for s set/frozenset:
* s.union(a, b, c,...)
* s.update(a, b, c,...)
* s.intersection(a, b, c,...)
* s.intersection_update(a, b, c,...)
By extension:
* set.union(a, b, c,...) # provided a is a set/frozenset
* ...
Union is extended by iterative application of set_union_internal
Intersection is optimized by sorting all sets/frozensets/dicts in
increasing order of size and only iterating over elements in the
smallest.

In 2.x, the size of C string needed for an environment variable used by
posix_execve was calculated using PyString_GetSize. In 3.0 this is
translated to PyUnicode_GetSize. However, in 3.0 the C string is the
UTF-8 encoded version of the unicode object, which doesn't necessarily
have the same length as what PyUnicode_GetSize reports.
The simplest solution I see is to use strlen() instead.

This bug is explained in the attached file. The list of lists does not
behave correctly when it is defined by the makeGrid function in the
attached file. When attempting to set the value of one element, it
actually sets multiple elements. The same operation works differently
when the list of lists is defined with a literal. I am using version
2.5.2 with Windows XP. I am just learning Python, so I may have gotten
some terminology wrong.

It seems the Cookie module has an odd behavior with whitespaces.
According to http://wp.netscape.com/newsref/std/cookie_spec.html and
http://en.wikipedia.org/wiki/HTTP_cookie#Cookie_attributes the 'Expires'
attribute of the cookie should have this format:
"Wdy, DD-Mon-YYYY HH:MM:SS GMT"
and this is recognized by all the browsers. The oddity comes when I try
to load or create a cookie with that attribute:
Python 2.5.2 (r252:60911, Apr 21 2008, 11:12:42)
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from Cookie import SimpleCookie
>>> cookies = SimpleCookie()
>>> cookies.load('foo=baz; expires=Sat, 10-Jun-1978 09:41:04 GMT')
>>> cookies
<SimpleCookie: foo='baz'>
>>> cookies['foo']['expires']
'Sat,'
>>> cookies.load('foo=baz; expires=2008-06-10T09:44:45.963024')
>>> cookies['foo']['expires']
'2008-06-10T09:44:45.963024'
It really seems the parser breaks on whitespaces.

argument useful

New submission from Bill Janssen <bill.janssen at gmail.com>:
Right now, the encoding argument added to
xml.dom.minidom.DOMObject.toxml() in Python 2.3 seems fairly useless.
It has to be UTF-8. But a one-line change to the implementation of
toprettyxml would make it useful; instead of the encoding error method
being "strict", make it "xmlcharrefreplace". So change
writer = codecs.lookup(encoding)[3](writer)
to
writer = codecs.lookup(encoding)[3](writer, "xmlcharrefreplace")

Subject: [New-bugs-announce] [issue3077] h2py char literal doesn work
In-Reply-To: <1213172768.79.0.156029263713.issue3077@psf.upfronthosting.co.za>
Message-ID: <1213172768.79.0.156029263713.issue3077@psf.upfronthosting.co.za>
New submission from Gabriel <misc at evotex.ch>:
Tools/scripts/h2py.py doesn't work with char literals in a define. This
was first reported in the following post :
http://mail.python.org/pipermail/python-list/2005-September/340608.html
The fix works, I have included the patch as h2py.py.patch2.
Also, the current thing that is done when a char literal is encountered
is to use the char's ordinal value. I think that this is misleading,
since in C, if you use a char literal you are usually meaning to check
for an ascii char value like so :
#define EXIT_CHAR 'x'
/* ..... */
if(char_read == EXIT_CHAR)
exit(0)
and not an integer/numeric value, and if you intend to do numerical
things then you'd use an integer/numeric value instead.
This is the way ctypes does it with their h2xml.py & xml2py.py scripts.
So currently, a defines like the following :
#define EXIT_CHAR 'x'
#define MASK 0xfe
#define LIMIT 4
give (after the h2py.py.patch2 being applied) :
EXIT_CHAR = 120
MASK = 0xfe
LIMIT = 4
and the second patch I am submitting (h2py.py.patch) makes it give :
EXIT_CHAR = 'x'
MASK = 0xfe
LIMIT = 4
which I think is a better interpretation of the intent of the defines.
So to resume :
h2py.py.patch2 : this fixes the bug, maintaining the way the original
h2py script tried to process a char literal.
h2py.py.patch : this fixes the bug, but makes a char literal become a
string literal in python instead of the ordinal value.

bad, bad, bad
In-Reply-To: <1213205007.57.0.132667292732.issue3079@psf.upfronthosting.co.za>
Message-ID: <1213205007.57.0.132667292732.issue3079@psf.upfronthosting.co.za>
New submission from Skip Montanaro <skip at pobox.com>:
This seems like a bug in optparse.OptionParser:
def exit(self, status=0, msg=None):
if msg:
sys.stderr.write(msg)
sys.exit(status)
def error(self, msg):
"""error(msg : string)
Print a usage message incorporating 'msg' to stderr and exit.
If you override this in a subclass, it should not return -- it
should either exit or raise an exception.
"""
self.print_usage(sys.stderr)
self.exit(2, "%s: error: %s\n" % (self.get_prog_name(), msg))
By default I think it should raise an exception when it encounters an
error, not exit. Programmers shouldn't be forced to subclass code in
the standard library to get recommended practice.
If you feel this behavior can't be changed in 2.6 it should at least
be corrected in 3.0.
The cruel irony is that inside OptionParser.parse_args it actually
catches both BadOptionError and OptionValueError but suppresses them
by calling self.error() within the except block... *arrgggghhh*...
The correct behavior there is (in my opinion) to get rid of the
try/except statement altogether and just let the exceptions propagate.
Other calls to self.error() should be replaced with suitable raise
statements.

unixccompiler.py breaks when set to a string

Message-ID: <1213276584.77.0.784242980637.issue3090@psf.upfronthosting.co.za>
New submission from Jesse Noller <jnoller at gmail.com>:
This is on osx 10.5.3, latest gcc tool chain.
I have $ARCHFLAGS set to "-arch i386" to prevent the OS/X gcc from
building PPC code (as I don't want/need it) - if I leave this set as-is,
other applications build without error, intel only.
If I don't unset it, here's the error:
File "/Users/jesse/open_source/subversion/python-
trunk/Lib/distutils/ccompiler.py", line 697, in compile
self._compile(obj, src, ext, cc_args, extra_postargs, pp_opts)
File "/Users/jesse/open_source/subversion/python-
trunk/Lib/distutils/unixccompiler.py", line 176, in _compile
compiler_so = _darwin_compiler_fixup(compiler_so, cc_args +
extra_postargs)
File "/Users/jesse/open_source/subversion/python-
trunk/Lib/distutils/unixccompiler.py", line 79, in
_darwin_compiler_fixup
compiler_so = compiler_so + ' ' + os.environ['ARCHFLAGS']
TypeError: can only concatenate list (not "str") to list
make: *** [sharedmods] Error 1
I've attached a possible patch for this which does a .split() on the os.environ['ARCHFLAGS'] variable, which fixes the issue

Communicating over HTTPS at the default port of 443:
import httplib
conn = httplib.HTTPSConnection("my-secure-domain.com")
conn.request("GET", "/")
res = conn.getresponse()
In the current implementation, the Host header sent in the request is:
Host: my-secure-domain.com:443
The ":443" is unnecessary because the default port of HTTPS is 443. The
attached patch file fixes this so that the Host header sent is simply:
Host: my-secure-domain.com

multiprocessing.c currently has code like this:

if (!temp)
return;
if (PyModule_AddObject(module, "flags", temp) < 0)
return;
PyModule_AddObject consumes the reference to temp, so it could
conceivable be deleted before the rest of this function finishes.

New submission from Marius Gedminas <marius at gedmin.as>:
I'm building developer documentation for an existing project that
already had reStructuredText files scattered in the source tree.
Unfortunately these use the same extension (.txt) as functional doctest
files, but fortunately tests live only in subdirectories named 'ftests'.
Unfortunately, sphinx doesn't support globs in exclude_dirs or
exclude_trees, so I cannot just exclude "**/ftests".
It would help me if I could specify the exclude_dirnames option that's
currently hardcoded inside BuildEnvironment.find_files in my conf.py.

New submission from Amaury Forgeot d'Arc <amauryfa at gmail.com>:
on Windows, the stat() function always returns True for some special
device names (nul, con, com1, lpt1...), even when followed by an extension.
Thus "import con" manages to find that "con.py" exists, and tries to
read from it... fun.
A solution is to use GetFileAttributes() instead.
Note that on python2.5.2, the error message suggest that we have such a
problem, but fortunately the error is still an ImportError::
>>> import nul
ImportError: DLL load failed: Le module sp?cifi? est introuvable.

abstract.c defines two functions _add_one_to_C and _add_one_to_F. These

they should get a Py or _Py prefix.

*Problem*
The directory structure of PCBuild8 differs from PCBuild in that each
project has its own subdirectory.
There is no subdirectory for _ssl, and the files that would belong in it
are also omitted.
*Solution*
The attached files, based on those included with the Python 2.5.2
PCBuild release for windows in the svn Python25 maintenance trunk
(http://svn.python.org/projects/python/branches/release25-maint/PCbuild/),
should be placed in a new directory PCBuild8\_ssl.
Once added to the parent solution file pcbuild.sln, the _ssl project
will simply build if the normal instructions have been followed.
*Changes*
Since this is a change in location, both _ssl.mak and build_ssl.py have
been altered to reflect the extra level of nesting.
As a result, the #pragma comment(lib, "Python25") in pyconfig.h did not
work. In order to add the appropriate directory to the LIB path in
_ssl.mak, build_py.py now takes an additional (second) command line
parameter derived from visual studio's $(PlatformName). This is used to
define an variable PLATFORM_NAME passed to _ssl.mak which is used to
deduce the directory containing python25.lib. The accompanying
_ssl.vcproj has been migrated from the Visual Studio 2003 vcproj file in
PCBuild, and passes the additional $(PlatformName) parameter.
_ssl.mak has also been adjusted to output a .pdb file and keep the root
_ssl directory clean, copying existing behaviour for all the other projects.
This has resulted in some ugly usage of special path splitting NMAKE
syntax (grep for %|fF.obj) which doesn't work with the @<< syntax. As a
result the link stage has been split across several lines. Someone with
a better knowledge of makefiles in general and NMAKE in particular can
probably improve on this, but it does work, and is otherwise legible.
Note that this sub-directory file structure is new in this release, and
that the Python3k trunk seems to be reverting to the flat file structure.
These additions are still helpful since they should just work out of the
box, and allow people using the current recommended build of Python
(2.5.2) to compile the ssl and hashlib modules.
*Additional Details*
Built on Windows XP SP2 with MSVS2005 SP1. Details appended to this message.
Built against openssl-0.9.8h, which is later than the standard Python25
distribution.
Note that the assembly file based build of openssl-0.9.8h, which is
triggered by build_ssl.py, currently has a small bug. See
http://www.mail-archive.com/openssl-dev at openssl.org/msg24059.html
This is easily fixed by the following one line change to
openssl-0.9.8h\crypto\perlasm\x86ms.pl
"In this file, the line 273 containing "$extra" should be removed to be
able to compile the generated assembly files."
If an openssl build has been attempted prior to this step, delete all
out32 and tmp32 directories under openssl-0.9.8h
*Code and Patch*
Attached is a zip file containing the altered files, and a patch
generated using cygwin's diff run with the command line -uarN.
The patch can be applied by:
cd PCBuild8
mkdir _ssl
cd _ssl
patch -u -p1 < [wherever_the_patch_file_is_downloaded_to]\_ssl.patch
*Tested*
Compiles and imports fine with Release and Debug builds. Other builds
(AMD, Itanium) untested.
*Build Details*

noticeable speedups in real-world situations, but here are the synthetic

New submission from Antoine Pitrou <pitrou at free.fr>:
This patch implements implicit except chaining (__context__) as per PEP
3134, or not quite. The difference is that PyErr_Set* functions do set
the __context__ attribute, otherwise I think it would make an annoying
discrepancy between exceptions generated by Python modules and
exceptions generated by C modules (especially when some parts are
written in C and others in Python, e.g. the io library).
Unimplemented are the modifications in exception reporting.

On Windows the author simple #defines SEM_VALUE_MAX to be LONG_MAX. I
used
a little cpp action to define it:
#ifndef SEM_VALUE_MAX
# ifdef _SEM_VALUE_MAX
# define SEM_VALUE_MAX _SEM_VALUE_MAX
# else
# define SEM_VALUE_MAX INT_MAX

I was just merging 2to3 work (and you'll have to do svnmerge.py merge in
Lib/lib2to3 for this to work) into py3k and was running the tests when
this rather alarming thing happended:
$ ./python.exe Lib/test/regrtest.py test_lib2to3

Fatal Python error: GC object already tracked

This probably isn't a lib2to3 problem, but that's how I got it.

Subject: [New-bugs-announce] [issue3115] os.listdir randomly fails on
occasions when it shouldn't
In-Reply-To: <1213483378.87.0.0889155831871.issue3115@psf.upfronthosting.co.za>
Message-ID: <1213483378.87.0.0889155831871.issue3115@psf.upfronthosting.co.za>
New submission from philipspencer <pspencer at fields.utoronto.ca>:
Python's os.listdir function has the following code in
Modules/posixmodule.c:
errno = 0
...
for (;;) {
Py_BEGIN_ALLOW_THREADS
ep = readdir(dirp);
Py_END_ALLOW_THREADS
if (ep == NULL)
break;
...
a bunch of other stuff, including PyString_FromStringAndSize
which calls malloc
...
}
if (errno != 0 && d != NULL) {
The assumption is that errno will be nonzero only if readdir failed.
However, this is not the case. GLibc's malloc will, in some rare cases,
set errno even when it succeeds. So, during one pass through the loop
errno gets set to ENOMEM and then it is still set to ENOMEM when the
final readdir returns null at the end of the directory listing.
The fix is to move the line "errno = 0" from outside the loop to
right before the readdir inside the loop. That is the only way to
ensure that, when the loop is exited with readdir returning null,
the condition "errno != 0" is equivalent to "readdir actually failed."
The attached patch does this. Without this patch, we experience
frequent failures with the python tools "creatrepo" and "repomanage"
when run on very large directories (> 5000 packages) on Fedora 8
systems; see RedHat bugzilla entry #451494. With the patch, the commands
work as expected.
The patch is against 2.5.1 but from what I can see of the posixmodule.c
code from SVN it should apply cleanly there too.

Subject: [New-bugs-announce] [issue3119] pickle.py is limited by python's
call stack

Message-ID: <1213589185.62.0.660916672679.issue3119@psf.upfronthosting.co.za>
New submission from Aaron Gallagher <habnabit at gmail.com>:
Currently, pickle.py in the stdlib is limited by the python call stack.
For deeply recursive data structures, the default recursion limit of 1000
is not enough. The patch attached modifies pickle.py to instead use a
deque object as a call stack. Pickler.save and other methods that increase
the recursion depth are now generators which may yield either another
generator or None, where yielding a generator adds it to the call stack.

New submission from Bob Farrell <robertanthonyfarrell at gmail.com>:
The documentation for the sys module says:
"stdout and stderr needn't be built-in file objects: any object is
acceptable as long as it has a write() method that takes a string
argument."
However, the logging module calls flush() and close() on
StreamHandler.stream (and stream may be stdout), yet stdout does not
apparently need to have these methods - this caused breakage for a
program of mine that redirects stdout and can import arbitrary modules
(it's an interactive interpreter).
The attached patch checks that these two methods exist (using hastattr)
before calling them.

New submission from Aldona Majorek <python at ada.majorek.org>:
Copy of issue 1579370
Programs using generators, exceptions and threads could crash.
I was not able to make plain python program to crash, but python program
embedded in C++ crashed very reliably.
No more crashes after applying patch from 2.5 version stopped helped.
I verified that bug and patch on python 2.4.3.
Looking at the source code in svn, the same but lurks in latest 2.3 and
2.2 (since generators were introduced).

New submission from Andr? Fritzsche <computercrustie at users.sourceforge.net>:
After struggling around with my code for nearly 1 hour now, I found out
that one of my regular expressions with a special string causes python
to hang up - not really hang up, because the processor usage is at
nearly 100%, so I think the regex machine is looping infinite.
Here is the regex-string:
re_exc_line = re.compile (
# ignore everything before the first match
r'^.*' +
# first group (includes second | third)
r'(?:' +
# second group "(line) (file)"
r'(?:' +
# (text to ignore, line [number])
r'\([^,]+\s*,\s*line\s+(?P<line1>\d+)\)' +
# any text ([filename]) any text
r'.*\((?:(?P<file1>[^)]+))*\).*' +
# end of second group
r')' +
# or
r'|' +
# third group "(file) (line)"
r'(?:' +
# ([filename])
r'\((?:(?P<file2>[^)]+))*\)' +
# any text (text to ignore, line [number]) any text
r'.*\([^,]+\s*,\s*line\s+(?P<line2>\d+)\).*' +
# end of third group
r')' +
# end of first group
r')' +
# any text after it
r'.*$'
, re.I
)
It should match either the construct:
1. """some optional text (text to ignore, line [12]) ([any_filename])
followed by optional text"""
or:
2. """some optional text ([any_filename]) (text to ignore, line [12])
followed by optional text"""
If first text matches, it is put into 'line1' and 'file1' and if the
second one matches into 'line2' and 'file2' of the groupdict.
For the upper both examples everything is ok, but having the following
string (I had to change some pathnames, because they contained customer
names):
msg = (
r"Error: Error during parsing: invalid syntax " +
r"(D:\Projects\retest\ver_700\lib\_test\test_sapekl.py, line 14) " +
r"-- Error during parsing: invalid syntax " +
r"(D:\projects\retest\ver_700\modules\sapekl\__init__.py, line 21) " +
r"-- Attempted relative import in non-package, or beyond toplevel " +
r"package")
used with the upper regex:
re_exc_line.match(msg)
is running for two hours now (on a 3Ghz Machine)!
I've attached everything as an example file and hope, I could help you.

Subject: [New-bugs-announce] [issue3129] struct allows repeat spec. without
a format specifier

Message-ID: <1213694469.69.0.0950890622628.issue3129@psf.upfronthosting.co.za>
New submission from Caleb Deveraux <carrus85 at gmail.com>:
I'm not exactly sure if this is a bug or by design. Within the struct
module, whenever you provide a format string containing a repeat count
with no associated format specifier, the count is silently ignored.
eg.
>>> struct.pack("12345")
''
>>> struct.pack("3s42", "abc")
'abc'
(This also happens with unpack*, and pack_into)
The attached patch changes the above behavior to the following:
>>> struct.pack("12345")
struct.error: repeat count given without format specifier
>>> struct.pack("3s42", "abc")
struct.error: repeat count given without format specifier
Unit tests are included.
The attached patch is built against revision 64324 of the python SVN
trunk. Odd behavior observed in both 2.6 (svn r64324), and 2.5.2.
(Tested on Ubuntu x86_64 w/ Linux kernel 2.6.24)

On windows, test_httpservers fails with the error:

return self._sock.send(b)
TypeError: send() argument 1 must be bytes or read-only buffer, not str
There are two problems there:
- Lib/http/server.py still looks for os.popen2 or os.popen3 to start a
subprocess; these functions have been removed, this code should be
rewritten using the subprocess module.
- the fallback method, which exec() the cgi script in the python
interpreter, fails because sys.stdout should be set to a TextIOWrapper,
not a binary socket file.
Certainly the fallback method could be removed: every platform
implements subprocess nowadays.

New submission from George Sakkis <george.sakkis at gmail.com>:
I'd like to propose a new function for inclusion to the inspect module
-- getcallargs(func, *args, **kwds) -- that returns a dict which maps
the formal arguments of a function (or other callable) to the values
passed as args and kwds, just as Python has to do when calling
func(*args, **kwds). For example:
>>> def func(a, b='foo', c=None, *x, **y):
... pass
>>> sorted(getcallargs(func, 5, z=3, b=2).items())
[('a', 5), ('b', 2), ('c', None), ('x', ()), ('y', {'z': 3})]
This is handy when writing decorators, or more generally when one would
want to do some minimal type checking without actually calling the function.
I have posted a recipe at
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/551779; I can
clean it up and submit a proper patch if it's deemed useful enough for
the stdlib.

Subject: [New-bugs-announce] [issue3136] [PATCH] logging.config.fileConfig()
compulsivly disable all existing loggers
In-Reply-To: <1213837323.33.0.0675974065144.issue3136@psf.upfronthosting.co.za>
Message-ID: <1213837323.33.0.0675974065144.issue3136@psf.upfronthosting.co.za>
New submission from Leandro Lucarella <llucax at gmail.com>:
When using logging.config.fileConfig() in a large project, with several
nested loggers, is very counterintuitive and annoying that this function
disable all non-configured-via-fileConfig() loggers, because it forces
the config file to configure *all* the loggers there, which makes the
file unmaintainable, and throws the beauty of hierarchical loggers to
the trash.
Attached is a sample patch that adds a new option
"disable_existing_loggers" to fileConfig() function (defaulting to True,
to make it backward-compatible) to control this behavior. If you like
the idea I can update the documentation and add some testcases too.
You can see a simple example about the problem and solution here:
log.py: http://pastebin.lugmen.org.ar/4204
log.ini: http://pastebin.lugmen.org.ar/4205
without the patch, the output is:
logger:DEBUG: log debug
logger:INFO: log info
logger:WARNING: log warning
logger:ERROR: log error
logger:CRITICAL: log critical
With the patch (and passing disable_existing_loggers=False to
fileConfig()) yields this output:
logger:DEBUG: log debug
logger:INFO: log info
logger:WARNING: log warning
logger:ERROR: log error
logger:CRITICAL: log critical
logger.sublogger:DEBUG: sublog debug
logger.sublogger:INFO: sublog info
logger.sublogger:WARNING: sublog warning
logger.sublogger:ERROR: sublog error
logger.sublogger:CRITICAL: sublog critical
As one could expect when reading the logging module docs:
"""
getLogger() returns a reference to a logger instance with the specified
if it it is provided, or root if not. The names are period-separated
hierarchical structures. Multiple calls to getLogger() with the same
name will return a reference to the same logger object. Loggers that are
further down in the hierarchical list are children of loggers higher up
in the list. For example, given a logger with a name of foo, loggers
with names of foo.bar, foo.bar.baz, and foo.bam are all children of foo.
Child loggers propagate messages up to their parent loggers. Because of
this, it is unnecessary to define and configure all the loggers an
application uses. It is sufficient to configure a top-level logger and
create child loggers as needed.

New submission from Geoffrey Bache <gjb1002 at users.sourceforge.net>:
If a python script receives SIGINT while the interpreter is starting up,
it's possible to get the message "import site failed; use -v for
traceback" printed on standard error and for execution to proceed. It
also seems to be possible to get half-imported modules and for the
script to fail later claiming that something like "os.getenv" doesn't exist.
If I do as instructed and use -v for traceback I get something like:
'import site' failed; traceback:
Traceback (most recent call last):
File "/usr/lib/python2.4/site.py", line 61, in ?
import os
File "/usr/lib/python2.4/os.py", line 683, in ?
import copy_reg as _copy_reg
File "/usr/lib/python2.4/copy_reg.py", line 5, in ?
"""
KeyboardInterrupt
I imagine there exists some code like
try:
import site
except:
sys.stderr.write("import site failed; use -v for traceback\n")
though I couldn't find any. If so, it seems clear that KeyboardInterrupt
needs to be re-raised, or Python's special handler for SIGINT installed
rather later.

I found this problem when adding "print" statements to multi-threaded
code. When applying the attached diff to a py3k installation, the output
on screen always contains some garbage.
The following code is an extract of fileio_write (in Modules/_fileio.c),
but the same behavior appears everywhere:
if (!PyArg_ParseTuple(args, "s#", &ptr, &n))
return NULL;
Py_BEGIN_ALLOW_THREADS
errno = 0;
n = write(self->fd, ptr, n);
Py_END_ALLOW_THREADS
io.BufferedWriter calls this function with a bytearray.
In this case, the GIL is released when holding a pointer to the
bytearray data.
But another thread may mutate the bytearray in between, the pointer
becomes stale and can lead to segfaults or funny results.

New submission from Mark Summerfield <mark at qtrac.eu>:
When you build 30b1 on Linux (I tried Fedora 8 and Xubuntu 8) you get a
message that make failed to find the bits to build "_gestalt", which I
think is a Mac-thing not a Linux thing.
Anyway, Barry asked me to add this as a bug.

The module renaming of urllib's modules (and the getting rid of urllib2)

New submission from Forest Wilkinson <forest at users.sourceforge.net>:
I was just browsing the development docs, and noticed that the new
left-side navigation bar wastes a lot of horizontal space on the web
page. It fills nearly a third of my browser window (at its usual size)
with useless blank space, at the expense of the pertinent information.
This makes it harder to get much use out of a docs window placed next to
my editor window, since I am now forced to switch active windows and/or
scroll around the docs window in order to read the section I'm working
with. In a few cases, it leaves space for so few words per line that
even the visible part of the docs actually become harder to read
(especially with text justification).
For comparison, here are screen shots from the old and new documentation:
http://hestiafire.org/forest/img/doc25.png
http://hestiafire.org/forest/img/doc26.png
Is this side bar going to be present in the final release of the python
2.6 docs? I hope not. It's a significant loss in readability, IMHO.

behavior
In-Reply-To: <1213903108.91.0.624214427386.issue3144@psf.upfronthosting.co.za>
Message-ID: <1213903108.91.0.624214427386.issue3144@psf.upfronthosting.co.za>
New submission from Justin Cappos <justincappos at hotmail.com>:
The behavior of popen vs popen[2-4] differs with respect to open file
descriptors (at least on the Linux implementation of popen). popen
does not close file descriptors, thus processes retain open file
descriptors from their parent. This is likely not desirable for
security and stability reasons.
If this isn't fixed, at a minimum it would be a good thing to document.
Here is an example that demonstrates the issue:
<<< start of open_and_popen.py>>>
# This will not be printed if popen closes file descriptors
import os
myfd = os.open("open_and_popen.py",os.O_RDONLY)
readfo = os.popen("python print_from_fd.py "+str(myfd),"r")
print "os.popen results in:"
print readfo.read()
# it will print the first line of the file here
readfo.close()
(junkinfo, readfo) = os.popen2("python print_from_fd.py "+str(myfd),"r")
junkinfo.close()
print "os.popen2 results in:"
print readfo.read()
# the child got an error, so this is just the error text
readfo.close()
os.close(myfd)
<<< end of open_and_popen.py>>>
<<< start of print_from_fd.py>>>
import os
import sys
print os.read(int(sys.argv[1]),60)
<<< end of print_from_fd.py>>>

New submission from Jean Brouwers <MrJean1 at Gmail.com>:
The multiprocessing module fails to build on Solaris 10 when using the
Sun C compiler. The failure is due to one missing symbol
SEM_VALUE_MAX.
Defining that symbol (e.g. as _POSIX_SEM_VALUE_MAX) builds the
_multiprocessing module for both 32- and 64-bit.
However, for 32-bit, 5 tests from test_multiprocessing fail due to the
missing _ctypes module. For 64-bit, the first 3 tests fail (like for
32-bit) but the 4th test hangs. Here is a log:
./python Lib/test/test_multiprocessing.py

Subject: [New-bugs-announce] [issue3155] Python should expose a
pthread_cond_timedwait API for threading
In-Reply-To: <1214004207.53.0.484694251636.issue3155@psf.upfronthosting.co.za>
Message-ID: <1214004207.53.0.484694251636.issue3155@psf.upfronthosting.co.za>
New submission from Gregory P. Smith <greg at krypto.org>:
Currently the threading module has loops in it such as
threading.Condition.wait's loop that attempts to acquire a lock in
non-blocking mode and if it fails, sleeps for a while and trys again.
(with exponential backoff of sleep time from 500us to 50ms in the
current implementation).
This is inefficient.
Perhaps pthread_cond_timedwait does the same thing internally in some
implementations but even if so, it will do it a lot more efficiently
than doing it in python.
We should expose a PyThread_acquire_lock API that accepts a timeout and
uses pthread_cond_timedwait (or the equivalent on other OSes) when
available.
caveats? This may alter behavior with regards to KeyboardInterrupt
exceptions coming in being processed or not depending on the particular
OS timedwait implementation.

New submission from A.M. Kuchling <lists at amk.ca>:
bytearray's methods aren't consistent in what they accept.
append() takes either an int or a character:
>>> b = bytearray('abc')
>>> b.append(76) ; b
bytearray(b'abcL')
>>> b.append('M') ; b
bytearray(b'abcLM')
.insert() accepts only integers:
>>> b.insert(0, 97) ; b
bytearray(b'aabcLM')
>>> b.insert(0, 'a') ; b
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: an integer is required
Both PEP 358 and the docstring for .append() only document 'int' as a
legal input, so I suspect append() is wrong here.

New submission from Stephen Lewis <thgfrj at gmail.com>:
The documentation for several methods in the sqlite3 library seems to be
at odds with the function names:
sqlite3.Cursor.fetchone --> "Fetches several rows from the resultset."
sqlite3.Cursor.fetchmany --> "Fetches all rows from the resultset."
sqlite3.Cursor.fetchall --> "Fetches one row from the resultset."
This is apparent on Ubuntu's packaged version 2.5.2-2ubuntu4, and a
quick glance at the online SVN repository implies that its present in
the trunk.
Also, it might be helpful the documentation for sqlite3.connect were to
mention that it takes a file name as a parameter :)

extension modules

New submission from Fernando P?rez <fer_perez at users.sourceforge.net>:
Doctest fails to find doctests defined in extension modules. With tools
like cython (http://cython.org) it's trivially easy to add docstrings to
extension code, a task that is much less pleasant with hand-written
extensions. The following patch is a minimal fix for the problem:
--- doctest_ori.py 2008-06-20 19:22:56.000000000 -0700
+++ doctest.py 2008-06-20 19:23:53.000000000 -0700
@@ -887,7 +887,8 @@
for valname, val in obj.__dict__.items():
valname = '%s.%s' % (name, valname)
# Recurse to functions & classes.
- if ((inspect.isfunction(val) or inspect.isclass(val)) and
+ if ((inspect.isfunction(val) or inspect.isclass(val) or
+ inspect.isbuiltin(val) ) and
self._from_module(module, val)):
self._find(tests, val, valname, module, source_lines,
globs, seen)
However, it is likely not sufficient as it doesn't take into account the
__test__ dict, for which probably the same change would work, just a few
lines later. Furthermore, the real issue is in my view in the
distinction made by inspect between isfunction() and isbuiltin() for the
sake of analyzing docstrings. isfunction() returns false for a function
that is defined in an extension module (though it *is* a function) while
isbuiltin returns True (though it is *not* a builtin).
For purposes of doctesting, doctest should simply care:
- That it is a function.
- That it has a docstring that can be parsed.
But in too many places in doctest there are currently assumptions about
being able to extract full source, line numbers, etc. Hopefully this
quick fix can be applied as it will immediately make doctest work with
large swaths of extension code, while a proper rethinking of doctest is
made.
BTW, in that process doctest will hopefully be made more modular and
flexible: its current structure forces massive copy/paste subclassing
for any kind of alternate use, since it has internally hardwired use of
its own classes. Doctest is tremendously useful, but it really could
use with some structural reorganization to make it more flexible (cleanly).

Message-ID: <1214068420.92.0.41617535069.issue3162@psf.upfronthosting.co.za>
New submission from Simon Cross <hodgestar at gmail.com>:
It appears that ssl.SSLSocket attempts to override some of the methods
socket.socket delegates to the underlying _socket.socket methods.
However, this overriding fails because socket.socket.__init__ replaces
all the methods mentioned in _delegate_methods.
These methods are: recv, recvfrom, recv_into, recvfrom_into, send and
sendto.
ssl.SSLSocket implements recv and send. Neither of these overrides will
actually work. ssl.SSLSocket also implements recv_from and send_to
which seem to be attempts to override recvfrom and sendto.
In the Py3k branch it looks like the overriding done by
socket.socket.__init__ is gone so that these methods are now potentially
overridable. This could potentially be emulated in trunk by checking for
the methods using hasattr(...) before overriding them.
I'm happy to create patches which fix the method names and clean up the
methods on both branches and add tests. I just want to check that I have
an accurate picture of what's needed before starting on them.

Message-ID: <1214082720.03.0.30402071522.issue3166@psf.upfronthosting.co.za>
New submission from Mark Dickinson <dickinsm at gmail.com>:
If n is a Python long, then one might expect float(n) to return the
closest float to n. Currently it doesn't do this. For example (with
Python 2.6, on OS X 10.5.2/Intel):
>>> n = 295147905179352891391L
The closest float to n is equal to n+1. But float(n) returns the
further of the two floats bracketing n, equal to n-65535:
>>> float(n)
2.9514790517935283e+20
>>> long(float(n))
295147905179352825856L
>>> n - long(float(n))
65535L
It's fairly straightforward to fix PyLong_AsDouble to return the closest
double to a given long integer n (using the round-half-to-even rule in
the case of a tie). The attached patch does this.
Having a correctly rounded float(n) can be useful for testing other
floating-point routines that are supposed to be correctly rounded.

New submission from Jason Williams <williamsjj at digitar.com>:
email/header.py:decode_header() Line 95: dec =
email.base64mime.decode(encoded)
Headers that contain Subject or From headers which are Base64 encoded
and are insufficiently padded raise a HeaderParseError. The actual
padding error is begin generated in binascii.a2b_base64 and bubbling up
as a HeaderParseError in header.py.
decode_header() should detect the padding error (Base64 text length does
not evenly divide by 3) and automatically add padding before handing off
to a2b_base64. The problem usually occurs with spam.
Example problem header:
Subject: =?iso-8859-1?B?
UHJldmVudCBGb3JlY2xvc3VyZSAmIFNhdmUgWW91ciBIb21lIA=?=
Properly Padded:
Subject: =?iso-8859-1?B?
UHJldmVudCBGb3JlY2xvc3VyZSAmIFNhdmUgWW91ciBIb21lIA==?=

test_pydoc relies on pristine data to verify that the tests pass.
Unfortunately there is no automated way to regenerate that pristine
data, making the test easily fail if something global (e.g., __loader__
attributes on all modules) is introduced.
This was seen on Python 3.0 but might also be an issue in 2.6.

should the functions in the operator module be deprecated (or at least

New submission from Skip Montanaro <skip at pobox.com>:
Back in April we had a thread on xmlrpclib's problematic handling of dates
before 1900:
http://thread.gmane.org/gmane.comp.python.devel/93273/focus=93309
I'm still of the opinion that strftime() is the culprit and xmlrpclib is
just an innocent bystander. Guido worried that to correct this we'd have
to
implement strftime() from scratch.
I took a different approach and scouted around for an existing version of
strftime() which we could suck into the distribution. I found a modified
version of the BSD 4.4 strftime which came with (I see to recall) Tcl.
The attached patch is against the py3k svn repo. It passes all tests as
far as I can tell.
Also, see http://bugs.python.org/issue1777412 which appears to be related.

Fedora 8 and Xubuntu 8 + solution

Message-ID: <1214212085.7.0.171574365182.issue3175@psf.upfronthosting.co.za>
New submission from Mark Summerfield <mark at qtrac.eu>:
I built Python 30b1 from the tarball on Fedora 8 and Xubuntu 8.
My only configure switch was --prefix to get a local build.
On both systems the only build error I got was:
Failed to find the necessary bits to build these modules:
_gestalt
which shouldn't matter because it is a Mac thing not a Linux thing (and
already reported)---there were no other error messages, so no warning
that multiprocessing wasn't working.
Running make test does _not_ indicate any problem with the
multiprocessing module (same output on both systems):
302 tests OK.
21 tests skipped:
test_bsddb3 test_cProfile test_codecmaps_cn test_codecmaps_hk
test_codecmaps_jp test_codecmaps_kr test_codecmaps_tw test_curses
test_kqueue test_normalization test_ossaudiodev test_pep277
test_socketserver test_startfile test_timeout test_urllib2net
test_urllibnet test_winreg test_winsound test_xmlrpc_net
test_zipfile64
Those skips are all expected on linux2.
If I run test_multiprocessing.py manually from the _build_ directory it
works fine.
But if I use the locally installed Python 3 (soft linked to python3 in
my PATH), on both systems I get this:
: python3 -V
Python 3.0b1
: python3 Lib/test/test_multiprocessing.py
Traceback (most recent call last):
File "Lib/test/test_multiprocessing.py", line 19, in <module>
import multiprocessing.dummy
ImportError: No module named multiprocessing.dummy
Now given that the tests all pass it seemed to me that the problem was
with the build rather than with the module itself, and that led to the
solution, which for both systems is the same simple command:
cp -R ~/download/Python-3.0b1/Lib/multiprocessing
~/opt/python30b1/lib/python3.0
So it seems that although the shared library is copied correctly from
the build directory, what has been forgotten is to copy the
multiprocessing directory itself.

Currently, os.startfile is implemented in Win32 only, but there are

As a result of http://portland.freedesktop.org, unix desktop has command
line tool named "xdg-open"
(http://portland.freedesktop.org/xdg-utils-1.0/xdg-open.html).
And MacOSX has 'open'
(http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/open.1.html)
command, and it can be used in same condition.

PyOS_InputHook processing

Message-ID: <1214238743.53.0.342771827236.issue3180@psf.upfronthosting.co.za>
New submission from Michael Abbott <michael at araneidae.co.uk>:
The (undocumented!) API for PyOS_InputHook has two defects which are
addressed in the attached patch (at least when using the readline
module): firstly the called hook currently has to guess that input will
come on descriptor 0; secondly, any Ctrl-C interrupts encountered during
the processing of the input hook are lost.
This loss of interrupts can be rather annoying. The attached patch
addresses these problems by redefining the API to PyOS_InputHook as
int PyOS_InputHook(int file_in);
where file_in is the descriptor to monitor (PyOS_InputHook need not
return until file_in is ready to read), and the return value is non-zero
if and only if processing was interrupted.
Testing for interruption is implemented in the HAVE_RL_CALLBACK and
HAVE_SELECT branch of Modules/readline.c; other uses retain their
original functionality (I believe!).
The attached patch was prepared against
http://svn.python.org/projects/python/trunk , current at the time of
writing.

New submission from Nick Edds <nedds at uchicago.edu>:
This is a small patch to the 2to3 tool, replacing some calls to
isinstance (x,y) with type(x) is y in the file pytree.py. Although there
is only a slight performance increase for each time this change is made,
the recursive nature of pattern matching means that isinstance was being
calling hundreds of thousands of times per file, so overall these minor
changes result in a 3-4% speed increase in my limited testing. It
currently fails only one test due to line 432 in test_pytree, because I
had to rename the type parameter to new_type so I could call type() on
something. But with the line in the test file changed, it passes all tests.

# SGI IRIX specific modules -- off by default.
Background:
- Python built on machine A and distributed to end-users.
Machine A happens to have the OpenSSL libraries.
- End-user runs our package incl. the pre-built Python on
machine B, which happens not to have the OpenSSL libraries,
or an incompatible version.
- hashlib imports _hashlib, which fails because of the
OpenSSL problem.
- hashlib tries to fall back to generic sha and md5 modules.
I had _sha and md5 enabled in Modules/Setup.dist, but
didn't know Python 2.5 needs more.
I found this out the hard way. It would be helpful to at least
have the extra two comments as suggested above. I think it would
be even better to not comment out the md5 and sha modules in
the original Python distribution since it just adds about 200k
of .o files (Linux). That's very cheap compared to the loss
in time if people have to figure out why import hashlib is
failing and how to work around the problem.

Message-ID: <1214286784.44.0.321359332465.issue3185@psf.upfronthosting.co.za>
New submission from Carsten Grohmann <cgrohmann at users.sourceforge.net>:
The current python documentation of the time module
(http://docs.python.org/lib/module-time.html) means that time.time()
returns the "seconds since the epoch, in UTC".
But in the current source documentation of the time module
(http://svn.python.org/view/python/trunk/Modules/timemodule.c?rev=64048&view=markup)
is written that "time() -- return current time in seconds since the Epoch".
time.time() returns the current local unix seconds during tests on a
system using Python 2.5.
Please adapt the documentation.
Thanks,
Carsten

New submission from Mark Dickinson <dickinsm at gmail.com>:
In Python 2.6, for a long n, hex(n) and oct(n) have a trailing 'L', while
bin(n) does not:
>>> hex(1L)
'0x1L'
>>> oct(1L)
'01L'
>>> bin(1L)
'0b1'
I'm guessing that this is intentional, and that the only reason hex(n) and
oct(n) still have a trailing 'L' is backwards compatibility, but I thought
I'd better check.

New submission from Mark Dickinson <dickinsm at gmail.com>:
2.6 adds float('inf') and float('nan') as cross-platform ways to
generate infinities and NaNs. The C99 standard (section 7.20.1.3,
paragraph 3) specifies that 'infinity' (in any case, with optional
preceding sign) should also be a valid input to strtod, and I propose
that in Python float('infinity') should correspondingly be valid.
Note that the IEEE 754 standard also states that 'inf' and 'infinity'
should be valid input string representations of infinity, and Python's
decimal module also allows both 'inf' and 'infinity'.
A patch is attached.
Unless I'm mistaken, this change is simple and unlikely to be
controversial. I plan to check it in in a week or two if there's no
feedback before then.

In Python 3.0, help(round) gives the following:
round(...)
round(number[, ndigits]) -> floating point number
Round a number to a given precision in decimal digits (default 0
digits).
This returns an int when called with one argument, otherwise a
float.
Precision may be negative.
But in Python 3.x, round(x, n) doesn't always return a float; for
example, if x is a Decimal or Fraction then round(x, 2) is again a
Decimal or Fraction (respectively).

In 2.5, exec(open(filename)), where filename refers to a file with
python code, executes the code.
In 2.5, open returns an open file, but in 3.0, open returns a stream,
and so exec (which wants "a string, file, or code object, not
TextIOWrapper") returns an error. exec should probably be able to handle
a stream.

New submission from Morten Lied Johansen <mortenjo at ifi.uio.no>:
Currently, running pydoc on a module will show you the documentation on
all regular methods, and all special methods (starting and ending in
double underscores).
Private methods (starting with a single underscore) are not included.
Some times, it would be nice to include docs for these methods aswell,
and a small change to pydoc.visiblename solves the problem.
I've included a patch that adds this behaviour as an option (-i for
include private names). The implementation isn't as clean as one would
hope for (sets a global flag), but was the best I could come up with in
the short time I had available. Feel free to make a better
implementation.
The patch is against python 2.5.

The documentation for the fractions module needs some rewriting---it
contains minor inaccuracies, outdated statements (e.g. the regex is
incomplete), and there are places that could use some clarification (e.g.
the description of __round__).
I plan to take care of this in the next few days, unless anyone else wants
to have a look. I'm making an issue of it so that it doesn't get
forgotten.

With 2.5.2 and 30b1 strings don't round trip like numbers do.
I guess it has been like this a long time so isn't a bug, but it does
seem inconsistent.
Both 2.5.2 and 30b1:
>>> x = 5
>>> x == int(repr(x))
True
>>> x = "Test Text"
>>> x == str(repr(x))
False
The reason is that an extra set of enclosing quotes are added.

New submission from Eric Sadit <donsadit at gmail.com>:
Hello,
I found a rare bug in heavy multithreading IO operations. The bug arises
under a stupid sequence of I/O operations. The sequence is not a normal
one, but the real problem is that the Python's interpreter crashes. The
correct behavior should be raise an IOError exception (I think).
The bug occurs when some thread closes a file or socket whilst other
thread tries to read or write from the same socket. The failure it's
inside the fileobject.c because tries to read or write the specified
data size inside a loop without check in every iteration if the object
is closed (it checks only outside the loop). The file object is set to
NULL and a SIGSEGV happens.
I'm a python developer (in the language, but not developer of the
language), so i really don't know anything about the best way to solve
this issue, and how the project it's managed. I can develop an script to
raise this bug if anyone it's interested in this problem. I'm already
owns one, but I don't find it, and the real program that arises the
error was rewritten so i don't have it.
Cheers
Eric Sadit

New submission from Justin Mazzola Paluska <jmp at mit.edu>:
The attached patch (unittest-disable.patch) allows methods in
unittest.TestCases to be "disabled". The patch is against
Python2.5 from Debian:
%python2.5
Python 2.5.2 (r252:60911, Apr 17 2008, 13:15:05)
[GCC 4.2.3 (Debian 4.2.3-3)] on linux2
Disabled tests are not run, but are "remembered" in the output of the
test program. For example, the attached sample_tests.py has two
tests, one of which has been disabled. The output is:
%python sample_tests.py
.D
----------------------------------------------------------------------
Ran 2 tests in 0.000s
OK
where the D indicates that a test has been disabled.
Disabling tests is useful if you're using a "test first" coding
workflow, as some tests may test functionality that hasn't been
implemented yet. The failures of these tests (with their noisy
tracebacks) makes it harder to concentrate on other, real failures
that may be occurring in your tests.

render correctly (html)

Message-ID: <1214426188.21.0.172463487619.issue3203@psf.upfronthosting.co.za>
New submission from Gerard M. Flanagan <grflanagan at gmail.com>:
A TOC tree should render in HTML as a single 'ul', but in certain
circumstances it appears as multiple ul's.
You can see the effect here:
http://docs.python.org/dev/c-api/index.html
and in fact in the Sphinx documentation itself:
http://sphinx.pocoo.org/contents.html
the 'toctree' here is not an individual entity but a vertical series of
ul's, each of which has a *single* item (li). You may be able to see the
slightly increased space between the ul's which would not be present if
these were all the children of a single parent.
This should be changed so that pages have a unique 'toc' element because:
- it would be easier for css and javascript to manipulate
- there may be accessibility issues (eg. non-visual readers may not
identify the toc as a single sequence of alternatives)
The reason for the current behaviour can be found in the method
'resolve_toctree' of class sphinx.environment.BuildEnvironment, line 863::
newnode = addnodes.compact_paragraph('', '', *tocentries)
`tocentries` is a list of `toctrees` [<toctree>, <toctree>,..] each of
which will end up as a ul, while a compact_paragraph has no html
representation; hence the observed effect.
One way to fix this is to replace the above line with the following::
newnode = nodes.bullet_list()
for entry in tocentries:
for item in entry.children:
assert isinstance(item, nodes.list_item)
newnode.append(item)
(and you can also take the opportunity here to add a unique id::
newnode['ids'].append('toc')
)
Note that this new code is a noop if `tocentries` only has one element,
at least as far as html is concerned.

New submission from Michiel de Hoon <mdehoon at users.sourceforge.net>:
PyMem_Malloc is called in the Util_ReadAhead function in bz2module.c.
The code checks if PyMem_Malloc returns NULL, but in that case no
MemoryError is raised. So, if in the following code:
>>> input = bz2.BZ2File("myfile.txt.bz2")
>>> for line in input:
... # do something with the line
Python runs out of memory during the for-loop, then the for-loop exits
without an Exception being raised. To the user, it appears that the end
of the myfile.txt.bz2 file was reached and that no error occurred.
In the attached patch, I call PyErr_NoMemory() if PyMem_Malloc fails.
This then raises the MemoryError exception as appropriate.

AssertionError
The same goes for multiprocessing.Array and multiprocessing.Value.
Comparing code to documentation it's obvious that lock argument can be
one of Lock, RLock or None objects (or any object with "acquire"
attribute), but not True or False. Also, looking at the code it seems
strange to me that 'lock' is a keyword-only argument. Why not use simple
default argument "lock=None" for Array() function?
Proposed patch tries to address these issues.

Following code:

fp.readline()

fp.close()
Won't do anything. I mean nor writing to file, nor raising exception.
Nothing.
I can't find any note about this crap. So, it is the best place for it.
P.S. It's my first bug-report and I think I was wrong in filling bug-

New submission from Geoffrey Bache <gjb1002 at users.sourceforge.net>:
Run the following code on Windows:
import subprocess, os
file = open("filename", "w")
try:
proc = subprocess.Popen("nosuchprogram", stdout=file)
except OSError:
file.close()
os.remove("filename")
This produces the following exception:
Traceback (most recent call last):
File "C:\processown.py", line 10, in <module>
os.remove("filename")
WindowsError: [Error 32] The process cannot access the file because it
is being used by another process: 'filename'
When the CreateProcess call fails the subprocess module should release
the handles it provides. Unfortunately it seems to raise WindowsError
before doing this.

As Tim Golden points out, this can be worked around by doing
os.close(file.fileno()) at the end instead of file.close()

New submission from Hans Ulrich Niedermann <hun at n-dimensional.de>:
According to "pydoc --help",
pydoc -p <port>
Start an HTTP server on the given port on the local machine.
The IP address pydoc binds to is not specified, thus I would expect it
to either bind to the local address or to the wildcard address.
Current behaviour of "pydoc -p 1234" is to bind to the IPv4-only
address 0.0.0.0:1234.
On a IPv4/IPv6 dual-stack machine, I would expect pydoc to listen to
either both 127.0.0.1:1234 and [::1]:<port>, or just [::]:<port> ([::]
also catches accesses to IPv4 addresses such as 127.0.0.1).
Then access to the pydoc webserver is
available both via IPv4 (e.g. http://127.0.0.1:1234/) and IPv6 (e.g.
http://[::1]:1234/), and in both cases via http://localhost:1234/
regardless whether localhost is resolved via IPv6 or IPv4.
Trivial patch attached (tested on Linux x86 machine with local IPv6
networking).

explanation: "Duck Typing"

Message-ID: <1214543459.76.0.157400708153.issue3214@psf.upfronthosting.co.za>
New submission from Paddy McCarthy <paddy3118 at users.sourceforge.net>:
The official glossary entry here:
http://docs.python.org/tut/node18.html#l2h-46
says:
"
duck-typing
Pythonic programming style that determines an object's type by
inspection of its method or attribute signature rather than by
explicit relationship to some type object ("If it looks like a duck
and quacks like a duck, it must be a duck.") By emphasizing interfaces
rather than specific types, well-designed code improves its
flexibility by allowing polymorphic substitution. Duck-typing avoids
tests using type() or isinstance(). Instead, it typically employs
hasattr() tests or EAFP programming.
"
I think it is should be changed to delete the use of hasattr and just
rely on EAFP as in the second example here:
http://en.wikipedia.org/wiki/Python_syntax_and_semantics#Exceptions
The text would then read:
"
duck-typing
Pythonic programming style that determines an object's type by
inspection of its method or attribute signature rather than by
explicit relationship to some type object ("If it looks like a duck
and quacks like a duck, it must be a duck.") By emphasizing interfaces
rather than specific types, well-designed code improves its
flexibility by allowing polymorphic substitution. Duck-typing avoids
tests using type(), hasattr() or isinstance(). Instead, it typically
employs an EAFP style of programming.
"
The reason is that a hasattr test only tests for an attribute name. If
it is present and say the method signature is wrong, then its the
excecution of the code using the attribute that will find that out so
it is redundant. Best to use EAFP for Duck typing as we trust you know
what it is you are doing.
- Paddy.

New submission from Craig Holmquist <craig at neurotronics.com>:
This is observed on Windows XP; I don't know if it affects other platforms.
Trying to import sqlite3 gives this error:
>>> import sqlite3
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
import sqlite3
File "C:\Python26\Lib\sqlite3\__init__.py", line 24, in <module>
from dbapi2 import *
File "C:\Python26\lib\sqlite3\dbapi2.py", line 27, in <module>
from _sqlite3 import *
ImportError: DLL load failed: The specified module could not be found.
A look at the dependencies for _sqlite3.pyd shows that it's trying to
link to a file called sqlite3.pyd, which doesn't exist. Renaming
sqlite3.dll to sqlite3.pyd doesn't work either, because then "import
sqlite3" causes Python to try to import that file as a Python module
(instead of C:\Python26\Lib\sqlite3\__init__.py).
In Python 2.5.2, the _sqlite3.pyd module correctly links to sqlite3.dll.
If there's already an issue regarding this I couldn't find it.

New submission from Sjoerd Mullender <sjoerd at acm.org>:
There are several errors in the msilib documentation. I'm sure I
haven't found them all, but here are some:
- add_data is documented to have two arguments. In reality it has three.
- Execute on a View object is documented to have an optional argument.
In reality it has a single required argument whose value may be None.
- When I click on any of the references to Microsoft documentation, I
get a page in Japanese. This is possibly more due to Microsoft than
anything else (the links do contain en-us so it is a tad surprising).
- There is extremely little information on how to actually use the module.

New submission from Nick Edds <nedds at uchicago.edu>:
This is an optimization in pytree.py specifically for the bare_name
pattern from fix_imports.py. It also has the isinstance change I
previously suggested piggybacked onto it. Because the bare_name pattern
is so massive (764 nodes!), it is very slow to call _recursive_matches
on it. This fix has a special bare_name_matches fix that uses an
iterative matching solution specifically tailored to the bare_name
pattern. From preliminary testing, it appears to be roughly 25-30%
faster than the previous version of 2to3. If I uncomment the fix_imports
test, it fails 6 of them, but they are the same ones failed by the
current version of 2to3 and it fails them in the same way, so I think it
works. As with my previous isinstance chance, a one line change to
test_pytree is required.

Lib Ref/Built-in Types/Sequence Types/Bytes and Byte Array Methods
The following set/frozenset and dict sections repeat (and for dicts,
expands upon) the constructor interface from the Built-in Functions
section. The sequence type sections do not. There should as least be a
reference back. "For the constructor interface, see xxx"
Similarly there is no mention here of the difference between bytes and
bytearray, as there is below for the difference between set and
frozenset. I think there should be here, in this section, even though
there is back in Built-in Functions.
(Sets/frozenset have the opposite problem in that Built-in Functions
makes no mention that one is mutable and the other is not. I also think
just one word for each should be added there too.)
"The bytes and bytearray types have an additional class method:
bytes.fromhex(string) " should be followed by
"bytearray.fromhex(string)" and
"This bytes class method returns a bytes object," changed to
"These class methods return a bytes or bytearray object,"
I don't think the line 'Example:' is needed.
A thread today on the Py3 lists again brought up the issue that just as
bytes can be created by either a literal or class call, they could be
represented on output by either, with possible confusion.
Guido responded

I suggest adding at the end:
"Just as a bytes objects can be constructed either with a literal or a
class constructor call, they could be represented on output either by a
literal or class constructor call. The literal was chosen as being
shorter, generally more useful, and consistent with how other classes
are displayed. Similarly, the display of bytearrays uses the
corresponding bytes literal. If you want to see the bytes of either
class as integers, use tuple.
>>> a, b = b'abc', bytes((1,2,3))
>>> a,b
(b'abc', b'\x01\x02\x03')
>>> tuple(a), tuple(b)
((97, 98, 99), (1, 2, 3))
>>> c = bytearray(a)
>>> c, tuple(c)
(bytearray(b'abc'), (97, 98, 99))
"

Subject: [New-bugs-announce] [issue3225] backport python 3.0 language
functionality to python 2.5 by adding 8 opcodes to ceval.c

Message-ID: <1214652619.02.0.198443521566.issue3225@psf.upfronthosting.co.za>
New submission from kai zhu <davidbranniganz at gmail.com>:
this patch touches only Python/ceval.c.
1. the only existing thing it modifies is PyEval_EvalFrameEx (adds 8
extra cases for the new 3.0 opcodes, doesn't mess w/ any of the existing
ones, or anything else as a matter of fact)
2. that, plus it defines (the new opcodes)
#define SET_ADD 17
#define STORE_MAP 54
#define STORE_LOCALS 69
#define LOAD_BUILD_CLASS 34
#define MAKE_BYTES 35
#define POP_EXCEPT 36
#define UNPACK_EX 94
#define BUILD_SET 109
and some backported vars & helper functions
only 2 contiguous areas of ceval.c is patched (1. & 2. - areas are
delimited by the comments '// py3k')
this simple patch seems sufficient in theory to allow the interpreter to
natively execute most of 3.0's language syntax (nonlocal, print,
extended unpacking... have been tested to work)
*the one exception being pep3102 - keyword-only arguments
i wrote 2 small scripts which gives an interactive function
'compile_py3k' similar to __builtin__.compile except it works only for
3.0 syntax. it doesn't actually compile, but rather cheats by querying
it to a python 3.0 server via pipe io.
here is an interactive demonstration of my script:
example demonstrating pep3132 extended unpacking syntax: a,b,*c = 1,2,3,4

for more info
anyway, i think it would b a great boost for python 3.0 (which i think
is very cool) if developers can test/develop it under the robust 2.5
environment. this patch plus some scripts could go a long way in making
that happen

New submission from Martina Oefelein <Martina at oefelein.de>:
The first use of PySet_GET_SIZE in dict_fromkeys (file dictobject.c) is applied to a PyDictObject. These seem to work by chance, as the PyDictObject and PySetObject have very
similar structure so that it does not matter if you cast a PyDictObject* to a PySetObject*. But if their structure ever diverges, this would cause unpredictable behaviour.
Thus, this use of PySet_GET_SIZE should probably be replaced with a call of PyDict_Size.
(There are two more calls to PySet_GET_SIZE resp. _PySet_NextEntry in the same function,
but these are OK as they actually apply to a set.)

New submission from Antoine Pitrou <pitrou at free.fr>:
Lib/encodings/idna.py claims to do the following when `input` is a
string object (lines 183-184, and see comment line 178: "IDNA allows
decoding to operate on Unicode strings, too"):
# Force to bytes
input = bytes(input)
This is obviously wrong, lacking an encoding parameter. It doesn't seem
to be covered in the test suite, and I don't know what the proper
semantics should be, so I leave it to someone else to find a fix.

I try to get working pipe emulation using Popen. I try to pass StringIO
object to p1.stdin of the first process and I got the following:
File "/usr/lib/python2.5/subprocess.py", line 587, in __init__
errread, errwrite) = self._get_handles(stdin, stdout, stderr)
File "/usr/lib/python2.5/subprocess.py", line 932, in _get_handles
p2cread = stdin.fileno()
AttributeError: 'cStringIO.StringI' object has no attribute 'fileno'
Aside from the fact I would hope that cStringIO could provide
self.fileno() I believe the error message should have been:
AttributeError: 'cStringIO.StringIO' object has no attribute 'fileno'

New submission from Martin Mokrejs <mmokrejs at users.sourceforge.net>:
Although I do appreciate that you try to improve python it is not clear
to me from http://docs.python.org/lib/module-subprocess.html:
1. Why the old functions have been deprecated
2. I can pipe together two processes. But how can I use pipe to feed the
first process of the two? The example at
http://docs.python.org/lib/node535.html is not sufficient. Show how to
bind together cat(1) and tr(1). Cat should read from STDIN and pass the
same to STDOUT, being read by tr(1).
3. Nowhere is explained what this magic really does:
output = p2.communicate()[0]
I figured out the result is e.g. a string of '\n' separated lines.
What is not clear whether at this very moment the processes get
started and whether one can still write on input to them. It seems
not, the p1.stdin has to be already populated with data.
Thanks.

Subject: [New-bugs-announce] [issue3238] backport python 3.0 language
functionality to python 2.6 by adding 7 opcodes to ceval.c
In-Reply-To: <1214770027.24.0.542856927114.issue3238@psf.upfronthosting.co.za>
Message-ID: <1214770027.24.0.542856927114.issue3238@psf.upfronthosting.co.za>
New submission from kai zhu <davidbranniganz at gmail.com>:
this patch touches only Python/ceval.c.
1. the only existing thing it modifies is PyEval_EvalFrameEx (adds 7
extra cases for the new 3.0 opcodes, doesn't mess w/ any of the existing
ones, or anything else as a matter of fact)
2. that, plus it defines (the new opcodes)
#define SET_ADD 17
#define STORE_LOCALS 69
#define LOAD_BUILD_CLASS 34 // 71 in py3k
#define MAKE_BYTES 35 // unused in py3k
#define POP_EXCEPT 36 // 89 in py3k
#define UNPACK_EX 94
#define BUILD_SET 109 // 104 in py3k
and some backported vars & helper functions
only 2 contiguous areas of ceval.c is patched (1. & 2. - areas are
delimited by the comments '// py3k')
this simple patch seems sufficient in theory to allow the interpreter to
natively execute most of 3.0's language syntax (nonlocal, print,
extended unpacking, ... have been tested to work)
*the one exception being pep3102 - keyword-only arguments
i wrote 2 small scripts which gives an interactive function 'compile_py3k'
similar to __builtin__.compile. its a wrapper function which queries
the byte-compiling task to a python 3.0 server via pipe io.
example demonstrating pep3132 extended unpacking syntax:
a,b,*c = 1,2,3,4
(note the backported 3.0 opcode used in line2 of the disassembly)

http://pypi.python.org/pypi?name=py3to2&version=20080628&:action=display
for more info on the script
anyway, i think it would b a great boost for python 3.0 (which i think
is very cool) if developers can test/develop it under the 2.x
environment. this patch plus some scripts to emulated 3k extensions
(bytes, bytearray, ...) can go a long way in making 3.0 available for
the masses.
ps. i've also attempted the reverse (forward-port 2.x opcodes to 3.0),
& its a bit more complicated (namely the PRINTxxx opcodes). if there's
significant interest in that, i could work on it a bit more, but my
current interest is in extending 3.0 functionality to the vast 2.x
software base.

I should note that I reduced the test case as much as I possibly could,
and the actual compiled source seems to affect the crash. I.e., if I
remove one of the unused imports, it doesn't crash; if I remove the
unused function foo(), it doesn't crash; if I change the "height"
variable passed to wrap_output(), it doesn't crash; if I remove the
reassignment of buf[0] in flush(), it doesn't crash.
I'm not sure if these crashes are due to an error in the script, or if
the script should even be capable of crashing Python in this manner.

New submission from Chris AtLee <chris at atlee.ca>:
httplib should support requests whose bodies are iterable objects. This
would facilitate doing large file uploads via HTTP since you wouldn't
have to load the entire file into memory to create the request string.

In-Reply-To: <1214849078.87.0.171093103517.issue3244@psf.upfronthosting.co.za>
Message-ID: <1214849078.87.0.171093103517.issue3244@psf.upfronthosting.co.za>
New submission from Chris AtLee <chris at atlee.ca>:
The standard library should provide a way to encode data using the
standard multipart/form-data encoding.
This encoding is required to support file uploads via HTTP POST (or PUT)
requests.
Ideally file data could be streamed to the remote server if httplib
supported iterable request bodies (see issue #3243).
