Subject: [New-bugs-announce] [issue1995] localeconv() does not encode
returned strings
In-Reply-To: <1201889628.47.0.925128224389.issue1995@psf.upfronthosting.co.za>
Message-ID: <1201889628.47.0.925128224389.issue1995@psf.upfronthosting.co.za>
New submission from Antoine Pitrou:
Some values in the dict returned by localeconv() may be non-ASCII
strings, yet they are not decoded according to the locale's character
set. This can be observed when the currency symbol is the euro sign:
>>> import locale
>>> locale.setlocale(locale.LC_MONETARY, 'fr_FR.UTF-8')
'fr_FR.UTF-8'
>>> locale.localeconv()['currency_symbol']
'\xe2\x82\xac'
>>> locale.setlocale(locale.LC_MONETARY, 'fr_FR.ISO8859-15')
'fr_FR.ISO8859-15'
>>> locale.localeconv()['currency_symbol']
'\xa4'
localeconv() is defined in the _locale module, which has no knowledge of
the current encoding - but the locale module does. So we could redefine
localeconv() in locale as a wrapper, to do the proper encoding dance.

I think the fix for this case is to do something
arbitrary but consistent if possible?

New submission from Ron Adam:
This patch removes the gui tk control panel and replaces it with a
navigation bar on the served web pages.
This offers a nicer user experience because one no longer needs to jump
back and forth between windows.
The navbar supports getting specific modules, searching modules, and
returning to the main module index. I believe the file source view is
safer also.
Possible issues...
+ Restarting the server without ending it causes an error do to the port
already being used. I think this is not new.
+ There may be some brakage if other applications depend on the tk
interface, but I don't think any do. Or at least none that I know of.
+ I haven't tested this on windows. (It works well on Ubuntu 7.10)

The posix module except that a pid_t, uid_t and gid_t always fit into a

The code should use long long where available or at least do some

Message-ID: <1202104327.86.0.976441820339.issue2006@psf.upfronthosting.co.za>
New submission from Bill Janssen:
I've been reading asyncore lately, and feel that it's showing its age.
Most loops of this sort (we developed something similar for ILU, about
15 years ago) contain handlers for timers and work tasks, in addition to
input handling. For timers, typically there's a list of tasks and
times, often with a repeat period. A system timer is set to the time of
the next task to fire, and the select() loop is exited when it fires.
The loop handler then looks down the list of timer tasks, and executes
those ready to run. Similarly, most loops of this sort include a list
of work tasks, and a policy for executing them, such as "take one task
from the front of the list and run it, then do the select". This allows
background tasks to get run that don't have associated input or output fds.

Message-ID: <1202170790.58.0.28997794645.issue2009@psf.upfronthosting.co.za>
New submission from Andrew Dalke:
I wrote a translator from the CFG used in the Grammar file into a form for PLY. I
found one problem with
varargslist: ((fpdef ['=' test] ',')*
('*' NAME [',' '**' NAME] | '**' NAME) |
fpdef ['=' test] (',' fpdef ['=' test])* [','])
This grammar definition is ambiguous until the presence/lack of a "*". PLY
complains:
state 469
(28) varargslist -> fpdef EQUAL test COMMA .
(32) varargslist_star -> fpdef EQUAL test COMMA .
(35) varargslist_star3 -> COMMA . fpdef
(36) varargslist_star3 -> COMMA . fpdef EQUAL test
(39) fpdef -> . NAME
(40) fpdef -> . LPAR fplist RPAR
! shift/reduce conflict for NAME resolved as shift.
! shift/reduce conflict for LPAR resolved as shift.
RPAR reduce using rule 28 (varargslist -> fpdef EQUAL test COMMA .)
COLON reduce using rule 28 (varargslist -> fpdef EQUAL test COMMA .)
STAR reduce using rule 32 (varargslist_star -> fpdef EQUAL test
COMMA .)
DOUBLESTAR reduce using rule 32 (varargslist_star -> fpdef EQUAL test
COMMA .)
NAME shift and go to state 165
LPAR shift and go to state 163
! NAME [ reduce using rule 32 (varargslist_star -> fpdef EQUAL test
COMMA
.) ]
! LPAR [ reduce using rule 32 (varargslist_star -> fpdef EQUAL test
COMMA
.) ]
fpdef shift and go to state 515
My fix was to use this definition when I did the translation.
varargslist: ((fpdef ['=' test] (',' fpdef ['=' test])*
(',' '*' NAME [',' '**' NAME] | ',' '**' NAME | [','])) |
('*' NAME [',' '**' NAME]) |
('**' NAME))
So far I've not found a functional difference between these two definitions, and
the only change to ast.c is to update the comment based on this section.
By making this change it would be easier for the handful of people who write
parsers for Python based on a yacc-like look-ahead(1) parser to use that file more
directly.

New submission from Christian Heimes:
The patch adds a free list of long objects with size 1 or -1. It has
quite a tremendous effect on code like list(range(1000)).
$ ./python -m timeit "for i in range(100): list(range(1000))"
Without patch:
10 loops, best of 3: 79 msec per loop
With patch:
10 loops, best of 3: 20.8 msec per loop

this patch adds a custom date formatting function, which does not have

This is a reminder for the comment on top of ceval.c:
/* XXX TO DO:
XXX speed up searching for keywords by using a dictionary
XXX document it!
*/
It was also suggested to disallow subclasses of str in variable names,
in order to optimize comparisons. This restriction is not necessary if a
dict lookup is used: comparisons are less frequent and will often
succeed when comparing pointers of interned strings.

is not in a "normal" directory.

Message-ID: <1202312744.16.0.269773483749.issue2020@psf.upfronthosting.co.za>
New submission from Peter Saunders:
When compiling python 2.5.1 on Solaris 10 (sparc and x86), with openssl
0.9.8e - test_md5 fails with No module named _sha256. (As does doing an
"import md5")
When compiling, setup.dist was modified, the ssl parts were uncommented,
and modified to use the directory that we have ssl installed in.
SSL=/opt/IB
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -R$(SSL)/lib -lssl -lcrypto
The compiling env (on sol x86):
CC=cc
CFLAGS=-xO5 -m32 -xarch=sse3 -xcache=generic -xchip=generic
CPPFLAGS=-I/opt/IB/include
CXX=CC
CXXFLAGS=-xO5 -m32 -xarch=sse3 -xcache=generic -xchip=generic
LDFLAGS=-L/opt/IB/lib -R/opt/IB/lib
LD_RUN_PATH=/opt/IB/lib
PATH=/usr/bin:/sbin:/usr/sbin:/opt/IB/bin:/usr/ccs/bin:/opt/SUNWspro/bin
configure --prefix=/opt/IBpython/2.5.1 --without-gcc --with-threads
However, if I modify setup.py, and replace every occurrence of
"/usr/local" with "/opt/IB" (we don't use /usr/local) - then it compiles
fine, and the md5 module works correctly.
Is it possible for this to be made a configure argument, or a
environment setting?

distance. Both these algorithms are useful in multiple domains, well

but are compute-intensive and prohibitively expensive when implemented
in pure Python.

CRLF files were used are long over and since Python is NOT "C" it should

If I have a class:
class Foo(object):
bar = property(lambda self: 'baz') # ignore the value's trivial nature
and then run:
>>> foo_obj = Foo()
>>> foo_obj.__dict__
... I would expect to see:
{'bar': 'baz'}
... and not:
{}
This would seem consistent with what a property is supposed to
masquerade as. Do you disagree?

t = Tuple()
t[0] # __getitem__ called with type(i) == int

New submission from Andr? Fritzsche:
shutil.destinsrc(src,dst)
Checks if 'dst' starts with 'src', which can return a wrong result if
'dst' even starts with 'scr' but isn't really a subdirector of it. E.g.
(src=r'C:\data', dst=r'C:\data.old') returned true, although dst isn't a
subdirectory of src.
I tried to fix this creating the absolute paths of 'dst' and 'src'
appended the path seperator, if there wasn't one. Then did the check
again and now the result is correct.
See the diff file I've appended (and hopefully created correctly)

Message-ID: <1202474070.06.0.68722243132.issue2049@psf.upfronthosting.co.za>
New submission from Tal Einat:
When IDLE is run with a subprocess, add a 'Restart Shell & Run Module'
item to the 'Run' menu in editor windows. Also add Alt-F5 as a hotkey
for this item.
This is what the 'Run Module' (F5) item used to do (when there was a
subprocess). As of this patch 'Run Module' will not restart the shell
under any circumstances.
The advantages of this are that the user has more control (can run a
module in the shell either with or without restarting). It also avoids
surprising users which wouldn't expect 'Run Module' to restart the shell.
Based on changes proposed by Doug on idle-dev:

New submission from stocker81:
Python's interpreter doesn't keep proper file permissions after
importing library. See the fallowing:
mk at laptop ~ $ echo "key='top secret'" > key.py
mk at laptop ~ $ chmod 600 key.py
mk at laptop ~ $ python
Python 2.4.4 (#1, Jan 8 2008, 21:22:16)
[GCC 4.1.2 (Gentoo 4.1.2 p1.0.1)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import key
>>>
mk at laptop ~ $ ls -l key.py*
-rw------- 1 mk mk 17 II 8 20:09 key.py
-rw-r--r-- 1 mk mk 120 II 8 20:09 key.pyc
mk at laptop ~ $
So, interpreter creates 644 pyo file (visible for all) which contains
secret data from 600 py file.
I think it should keep the original permissions, someone can save a
important data (eg. SQL login/pwd into Django's settings.py) into
library and makes it visible for all by an accident.

Message-ID: <1202515821.86.0.159216664847.issue2053@psf.upfronthosting.co.za>
New submission from Tal Einat:
In many places in the code, tkMessageBox dialogs were being used
directly, with the master (parent) widget being set explicitly to the
EditorWindow's text widget. Only in some cases was the focus being set
to the text widget afterwards, although in most this is the Right Thing
To Do.
This patch adds a decorator which wraps a tkMessage box (or similar)
function to use the EditorWindow's text widget as a parent by default
and set focus back to it afterwards. This is used to wrap the showerror
and ask* methods. It also changes the code to use these methods wherever
appropriate.
All in all, the change in functionality is that the dialogs' parent
widget will always be the text widget, and that focus will always be
returned to it. This makes the interface more consistent. As a bonus, a
lot of repetitive cruft is removed from the code, and writing extensions
is made another bit simpler.

option
In-Reply-To: <1202609145.39.0.17652822204.issue2056@psf.upfronthosting.co.za>
Message-ID: <1202609145.39.0.17652822204.issue2056@psf.upfronthosting.co.za>
New submission from Lenard Lindstrom:
The install command returns the following error when the --compiler
option is provided on the command line:
>python setup.py install --compiler=mingw32
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help
error: option --compiler not recognized
This is problematic on Windows when MinGW is being used in place of
Visual C. A package can be built with --compiler=mingw32, but if no
compiler is specified for install the following error occurs:
>python setup.py install
running install
running build
running build_py
running build_ext
error: Python was built with Visual Studio 2003;
extensions must be built with a compiler than can generate compatible
binaries.
Visual Studio 2003 was not found on this system. If you have Cygwin
installed,
you can try compiling with MingW32, by passing "-c mingw32" to setup.py.
The work-around is to specify compiler=mingw32 in a setup.cfg file under
a [build] or [build_ext] heading. But this would be inconvenient for
someone who has both Visual C and MinGW and wants to choose.

difflib alone and bundled Tools\Scripts\diff.py utility are both very
useful, esp. on windows platforms where standard unix diffutils are
absent. However, python difflib still doesn't have a patch counterpart

Message-ID: <1202643843.0.0.134352659823.issue2058@psf.upfronthosting.co.za>
New submission from Lars Gust?bel:
tarfile.py wastes lots of memory resources. The memory consumption does
not depend on the size of an archive but on the numbers of members in it.
The attached patch reduces memory usage by about 60% and consists of two
independent strategies (each with about 30% reduction):
1. Add __slots__ to the TarInfo class. This was proposed in issue1540385
a while ago but rejected due to backward-compatibility issues.
2. Remove the undocumented buf attribute of the TarInfo class. buf
stores the original 512-byte header block read from the archive. This
was introduced in r45954 and is rather useless except for GNUTYPE_SPARSE
processing. This might as well be a candidate for backporting to 2.6.

Given that Tix imports all names from Tkinter this is likely to result
in confusion.
E.g.
>>> from Tix import *
>>> print Button
Tkinter.Button
>>> print OptionMenu
Tix.OptionMenu
To get to Tkinter's OptionMenu, one needs to do something like
import Tkinter
Tkinter.OptionMenu

def setStyle(self, stylename, value):
style = Style()
style.stylename = stylename
style.value = value
self.styles[stylename]=style

widget = Widget()
widget.setStyle(stylename,value)
self.widgets.append(widget)
>>> container = Container()

'red'
>>> container.addWidget('backgroundColor','blue')
>>> container.widgets[0].styles['backgroundColor'].value

>>> container.widgets[1].styles['backgroundColor'].value

>>>
If I am doing something wrong here, please let me know. But it seems to
me to be an error that List.append() will overwrite existing entries
when using the code above - -

New submission from Amaury Forgeot d'Arc:
Since r60696, WINVER is forced to _WIN32_WINNT_WIN2K. This has two problems:
- Vs8 (and before) does not define _WIN32_WINNT_WIN2K. It should be
replaced with 0x500.
- When WINVER is set to 0x500, vc6 gives a long warning because at the
time, windows nt 5.0 was only at beta stage. Moreover, there are other
clashes between winsock.h and winsock2.h, that show up when WINVER is 0x500.
To correct this, I propose:
- To replace _WIN32_WINNT_WIN2K and similar constants by their values.
- That 0x500 is not the required value, but the *maximum* value
necessary when targeting win2k. VC6 can set it to 0x400.
I'll try a patch later tonight.

a *huge* charset, in cjkcodecs

Message-ID: <1202731134.77.0.201279568783.issue2066@psf.upfronthosting.co.za>
New submission from Hye-Shik Chang:
This patch adds CNS11643 support into Python unicode codecs.
CNS11643 is a huge character which is used in EUC-TW and ISO-2022-CN.
CJKCodecs have had the CNS11643 support for 4 years at least,
but I dropped it because of its huge size in integrating into Python.
EUC-TW and ISO-2022-CN aren't being used widely while they are
still regarded as part of major encodings yet.
In my patch, disabling the CNS11643 charset support is possible by
adding -DNO_CNS11643 in CFLAGS for light platforms. Mapping source
code size of the charset is 900K and it adds about 350K into
_codecs_tw.so (in POSIX) or python26.dll (in Win32).
What do you think about adding this code?

about rpc_paths might be wrong
In-Reply-To: <1202756969.25.0.603492596378.issue2072@psf.upfronthosting.co.za>
Message-ID: <1202756969.25.0.603492596378.issue2072@psf.upfronthosting.co.za>
New submission from Stefan Schwarzburg:
In the documentation for SimpleXMLRPCServer
(http://docs.python.org/lib/simple-xmlrpc-servers.html)it is said, that
the SimpleXMLRPCServer object has an attribute "rpc_paths" that could be
set to valid path portions.
This would mean that changing the example code on the same page by
adding a line like:
[...]
server = SimpleXMLRPCServer(("localhost", 8000))
server.rpc_paths = ('/test')
[...]
would result in a call to 'http://localhost:8000/test' be processed
correctly. But this is not the case.
The server object has no attribute 'rpc_paths' nor does creating an
attribute like this change anything.
What however works is a line like this:
[...]
server.RequestHandlerClass.rpc_paths = ('/test')
[...]
The reason for this is that the test 'is_rpc_path_valid' is a method of
the class SimpleXMLRPCRequestHandler which tests if the path is in the
class attribute 'rpc_paths' of SimpleXMLRPCRequestHandler. This class is
saved as RequestHandlerClass in SimpleXMLRPCServer.
So the behavior of the code is understandable but is not described by
the documentation.

In-Reply-To: <1202784439.48.0.0759142195952.issue2074@psf.upfronthosting.co.za>
Message-ID: <1202784439.48.0.0759142195952.issue2074@psf.upfronthosting.co.za>
New submission from Simon Percivall:
_safe_repr() tries to handle the case where two objects are unorderable by
ordering on (str(type(key)), key, value), but this fails when
str(type(key)) is equal for two objects, but key is different and
unorderable. Easy fix: order just on the string representation.

Subject: [New-bugs-announce] [issue2076] xmlrpclib closes connection after
each call
In-Reply-To: <1202814252.95.0.393197834217.issue2076@psf.upfronthosting.co.za>
Message-ID: <1202814252.95.0.393197834217.issue2076@psf.upfronthosting.co.za>
New submission from Erno Kuusela:
xmlrpclib is using the old HTTP and HTTPS classes from httplib which are
to quote the docstring, "Compatibility classes with httplib.py from 1.5."
and force the use of HTTP 1.0. This prevents connection reuse and
pipelining.
Attacked is some code we are using as a workaround.
Is the xmlrpclib in the standard library required to keep compatibility
with old python versions?

New submission from Rupert Summerton:
1. Description: The Python interpretor is crashing on shutdown due to a
segmentation fault:
Unhandled exception at 0x1e03d41f in python.exe: 0xC0000005: Access
violation reading location 0x0000002c.
2. Reproducibility: At least 10% on Windows XP Professional SP2, P4
3.20GHz, 2.00GB RAM, when running the attached module, threadpool.py.
(Running with Python 2.5.1). Unfortunately I cannot get the attached
test case to crash on Linux or Solaris. However, executing this code as
part of our Python test framework (see context below), with Python
2.4.1, what looks like the same crash produced the following backtrace:

3. Context: We have an automated test framework written in Python. To
speed up execution it has been multi-threaded so that tests can be run
in parallel. Rather than re-invent the wheel we simply used this
threadpool (http://chrisarndt.de/en/software/python/threadpool/), work
requests essentially being calls to a method that runs an individual
test case. However, we have substantially modified the code to add
functionality. Specifically, we need to find a way to limit the number
of tests that can run concurrently because: (1) different tests place
different loads on a machine, and (2) different machines have different
capacities (CPUs, memory, etc.). We do this by associating a cost with
each work request, and by using the number of CPUs on the machine as a
limit (crude, but reasonably effective) -- if running the next job would
exceed the cost limit, the thread sleeps, and then checks again. In
order to verify that this cost logic works, we have also added some
logging code that can be activated by setting a flag. The other
significant modification has been to extend the Python Queue module to
add a peek method, because peeking at the front of the job queue to
determine the cost of the next job, and not removing it until there is
sufficient capacity to run it, speeds up the execution of tests. The
crash in the Python interpretor occurs only when (1) the cost logging is
switched on AND (2) the module peekablequeue is used instead of the
built in Queue module. I am quite willing to believe that these
modifications could be better implemented, but however bad the code, the
Python interpretor should not crash.

Subject: [New-bugs-announce] [issue2078] CSV Sniffer does not function
properly on single column .csv files
In-Reply-To: <1202832132.24.0.528453630912.issue2078@psf.upfronthosting.co.za>
Message-ID: <1202832132.24.0.528453630912.issue2078@psf.upfronthosting.co.za>
New submission from Jean-Philippe Laverdure:
When attempting to sniff() the dialect for the attached .csv file,
csv.Sniffer.sniff() returns an unusable dialect:
>>> import csv
>>> file = open('listB2Mforblast.csv', 'r')
>>> dialect = csv.Sniffer().sniff(file.readline())
>>> file.seek(0)
>>> file.readline()
>>> file.seek(0)
>>> reader = csv.DictReader(file, dialect)
>>> reader.next()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/soft/bioinfo/linux/python-2.5/lib/python2.5/csv.py", line 93,
in next
d = dict(zip(self.fieldnames, row))
TypeError: zip argument #1 must support iteration
However, this works fine:
>>> file.seek(0)
>>> reader = csv.DictReader(file)
>>> reader.next()
{'Sequence': 'AALENTHLL'}
If I use a 2 column file, sniff() works perfectly.
It only seems to have a problem with single column .csv files (which are
still .csv files in my opinion)
Thanks for looking into this.

New submission from hauser:
This construction:
__import__( 'pkg', {}, {}, [''] )
Will cause double initialization of package 'pkg', once with name 'pkg'
and second one with name 'pkg.' (trailing dot). Implementation tries to
import subpackage of 'pkg' with empty name, and imports the same package
twice.
This kind of construction is used as a hacky way to obtain exact module
instead of top-level module in return value. It is a hack, but should
not cause this kind of side effects.

New submission from Joseph Armbruster:
I receive the following warning when running the test_unicode_file unit
tests out of the trunk (60758)
python -E -tt ../../lib/test/regrtest.py -g "test_unicode_file"
test_unicode_file
D:\work\pytrunk\lib\test\test_unicode_file.py:103: UnicodeWarning:
Unicode equal comparison failed to convert both arguments to Unicode -
interpreting them as being unequal
filename1==filename2
D:\work\pytrunk\lib\shutil.py:36: UnicodeWarning: Unicode equal
comparison failed to convert both arguments to Unicode - interpreting
them as being unequal
os.path.normcase(os.path.abspath(dst)))
1 test OK.
It looks like the warning was meant to be suppressed in
test_unicode_file.py line 104:
# Try using shutil on the filenames.
try:
filename1==filename2
except UnicodeDecodeError:
# these filenames can't be compared - shutil.copy tries to do
# just that. This is really a bug in 'shutil' - if one of shutil's
# 2 params are Unicode and the other isn't, it should coerce the
# string to Unicode with the filesystem encoding before comparison.
pass
This does not handle the UnicodeWarning, was it meant to?

Hi,
the attached code in t.py fails to run:
class C (object):

return 42

$ python t.py
Traceback (most recent call last):
File "t.py", line 5, in ?
print C() | C()
TypeError: unsupported operand type(s) for |: 'C' and 'C'
If I use old style classes (ie. "class C:" instead of "class
C(object):"), the code runs fine. I suspect that the method lookup for
special operator methods is different in new style classes, but why?
This might also be related to issue #643841 but I am not sure.

before the signal is valuable)
The bug happens only when stdout and stderr are not merged and is tested

The copy module will not properly copy/deepcopy weakrefs, it will bomb

difficult.
To replicate:
import copy, weakref
class Test(object): pass
t = Test()
wr = weakref.ref(t)

New submission from Ralf Schmitt:
mmap.flush returns the result of the call to FlushViewOfFile as an
integer, and does not check for errors. On unix it does check for
errors. The function should return None and raise an exception if an
error occurs...
This bug can lead to data loss...
Here's the current version of that function:
static PyObject *
mmap_flush_method(mmap_object *self, PyObject *args)
{
Py_ssize_t offset = 0;
Py_ssize_t size = self->size;
CHECK_VALID(NULL);
if (!PyArg_ParseTuple(args, "|nn:flush", &offset, &size))
return NULL;
if ((size_t)(offset + size) > self->size) {
PyErr_SetString(PyExc_ValueError, "flush values out of range");
return NULL;
}
#ifdef MS_WINDOWS
return PyInt_FromLong((long) FlushViewOfFile(self->data+offset, size));
#elif defined(UNIX)
/* XXX semantics of return value? */
/* XXX flags for msync? */
if (-1 == msync(self->data + offset, size, MS_SYNC)) {
PyErr_SetFromErrno(mmap_module_error);
return NULL;
}
return PyInt_FromLong(0);
#else
PyErr_SetString(PyExc_ValueError, "flush not supported on this system");
return NULL;
#endif

New submission from Armin Rigo:
It's hard to tell for sure, given the lack of precise definition, but I
believe that the attached piece of code "should" work. What it does is
make p1 point to c_long(20). So ctypes should probably keep the
c_long(20) alive as long as p1 is alive (and not further modified).
This test shows that the c_long(20) gets freed instead, making the
p1.contents reference garbage.

default
In-Reply-To: <1203086575.38.0.209227458245.issue2124@psf.upfronthosting.co.za>
Message-ID: <1203086575.38.0.209227458245.issue2124@psf.upfronthosting.co.za>
New submission from A.M. Kuchling:
The W3C posted an item at
http://www.w3.org/blog/systeam/2008/02/08/w3c_s_excessive_dtd_traffic
describing how their DTDs are being fetched up to 130M times per day.
The Python parsers are part of the problem, as
noted by Paul Boddie on the python-advocacy list:
There are two places which stand out:
xml/dom/xmlbuilder.py
xml/sax/saxutils.py
What gives them away is the way as the cause of the described problem is
that
they are both fetching things which are given as "system identifiers" - the
things you get in the document type declaration at the top of an XML
document
which look like a URL.
If you then put some trace statements into the code and then try and parse
something using, for example, the xml.sax API, it becomes evident that by
default the parser attempts to fetch lots of DTD-related resources, not
helped by the way that stuff like XHTML is now "modular" and thus employs
lots of separate files in the DTD. This is obvious because you get
something
like this printed to the terminal:
saxutils: opened http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd
saxutils: opened http://www.w3.org/MarkUp/DTD/xhtml-inlstyle-1.mod

saxutils: opened http://www.w3.org/MarkUp/DTD/xhtml-blkstruct-1.mod
saxutils: opened http://www.w3.org/MarkUp/DTD/xhtml-blkphras-1.mod
Of course, the "best practice" with APIs like SAX is that you define
your own
resolver or handler classes which don't go and fetch DTDs from the W3C all
the time, but this isn't the "out of the box" behaviour. Instead,
implementers have chosen the most convenient behaviour which arguably
involves the least effort in telling people how to get hold of DTDs so that
they may validate their documents, but which isn't necessarily the "right
thing" in terms of network behaviour. Naturally, since defining specific
resolvers/handlers involves a lot of boilerplate (and you should try it in
Java!) then a lot of developers just incur the penalty of having the
default
behaviour, instead of considering the finer points of the various W3C
specifications (which is never really any fun).
Anyway, I posted a comment saying much the same on the blog referenced
at the
start of this thread, but we should be aware that this is default standard
library behaviour, not rogue application developer behaviour.

New submission from Floris Bruynooghe:
The msilib documentation mentions that read support of MSI files is
supported, however the actual methods on the Record class for it are
missing. This patch wraps two more functions from the MSI API to the
record class, enabling to read integers and strings. The only one left
then (AFAIK) is "Stream" but I didn't need that so couldn't test it.

strings

Message-ID: <1203179266.7.0.767749493824.issue2128@psf.upfronthosting.co.za>
New submission from Giovanni Bajo:
Under Windows, sys.argv is created through the Windows ANSI API.
When you have a file/directory which can't be represented in the
system encoding (eg: a japanese-named file or directory on a Western
Windows), Windows will encode the filename to the system encoding using
what we call the "replace" policy, and thus sys.argv[] will contain an
entry like "c:\\foo\\??????????????.dat".
My suggestion is that:
* At the Python level, we still expose a single sys.argv[], which will
contain unicode strings. I think this exactly matches what Py3k does now.
* At the C level, I believe it involves using GetCommandLineW() and
CommandLineToArgvW() in WinMain.c, but should Py_Main/PySys_SetArgv() be
changed to also accept wchar_t** arguments? Or is it better to allow for
NULL to be passed (under Windows at least), so that the Windows
code-path in there can use GetCommandLineW()/CommandLineToArgvW() to get
the current process' arguments?

Currently "optparse" module lacks "bool" data type parsing. It would be
nice to add this feature.

incorrect end-of-line, wiriting broken Unicode (UTF-8) files

New submission from Technologov:
"codecs" module on Windows writes incorrect end-of-line, making it
impossible to write Unicode files.
See below, how-to reproduce bug (Python 2.5.1 on Windows XP)
===================================================================
#buggy unicode support module:
import codecs
filewr=codecs.open('myfile.txt','w','utf-8')
filewr.write("abc"+"\n")
===================================================================
Now, try to open this 'myfile.txt' using Windows Notepad.
The bug is perfectly visible.
The code below, will give correct results however:
===================================================================
filewr=open('myfile.txt','w')
filewr.write("abc"+"\n")
===================================================================
Basically this bugs _prevents_ me from writing Unicode text files.
NOTE: I'm not sure, if this bug should relate to "Windows" or "Unicode"
component.
NOTE: This bug is reproducible, even without writing Unicode characters.

New submission from Nathan Duran:
The following code:
import smtplib
test = smtplib.SMTP('mail.host.com')
will hang the entire script for about ten minutes when run on a machine
which is connected to the internet via an ISP who blocks port 25 (which is
pretty much all of them these days). Closer inspection of the smtplib
sources reveals that it is making use of blocking sockets, which is all
well and good, but I do not believe they should be allowed to block for
such a ridiculously lengthy period of time.
My task is to walk the list of MX records provided by a DNS query, connect
to each server listed and check a user-supplied address for validity. If I
have to wait 10 minutes for an exception to be thrown for each
unresponsive server, this process could easily take hours per address,
which is completely unacceptable.
My workaround is to ditch smtplib entirely and write my own socket code,
but setting a timeout on a socket throws it into non-blocking mode, which
is not entirely what I want, either. PHP allows one to apply a perfectly
sane timeout to a blocking socket without any difficulty, and this is
something I'm frankly rather surprised to see Python choke on.
What I'd expect to see is an exception after less than a minute's worth of
repeated failures so the caller can catch it and try another port.

A typo ('#fffff' instead of '#ffffff') in pydoc.py causes the "Modules"
section to have cyan text instead of white text. I don't believe this is
deliberate because (a) it looks wrong and (b) anyone doing that
deliberately would have put a '0' in the color to make it look
deliberate. This patch doesn't address the large-scale duplication of
'#ffffff' (instead of using a constant, or even the named color
'white'), and just adds the single missing character.

New submission from Guilherme Polo:
function generate_tokes at tokenize.py yields token OP (51) for colon,
while it should be token COLON (11). It probably affects other python
versions as well.
I'm attaching a minor sample that demonstrates this, running it returns
the following output:
1 'if' (1, 0) (1, 2) if a == 2:
1 'a' (1, 3) (1, 4) if a == 2:
51 '==' (1, 5) (1, 7) if a == 2:
2 '2' (1, 8) (1, 9) if a == 2:
51 ':' (1, 9) (1, 10) if a == 2:
1 'print' (2, 0) (2, 5) print 'hey'
3 "'hey'" (2, 6) (2, 11) print 'hey'
0 '' (3, 0) (3, 0)
I didn't check if there are problems with other tokens, I noticed this
with colon because I was trying to make some improvements on tabnanny.

importer objects
In-Reply-To: <1203289879.4.0.29225339307.issue2135@psf.upfronthosting.co.za>
Message-ID: <1203289879.4.0.29225339307.issue2135@psf.upfronthosting.co.za>
New submission from Douglas Greiman:
This patch reorganizes import.c to move functionality into two new PEP
302-style Importer objects. I attempted to change as little as
feasible, but the patch is still ~4700 lines long, about 1000 of which
is new tests.
BuiltinImporter: handles C_BUILTIN and PY_FROZEN modules
DirectoryImporter: handles PY_SOURCE, PY_COMPILED, PKG_DIRECTORY,
C_EXTENSION modules
BuiltinImporter is put on sys.meta_path, DirectoryImporter is put on
sys.path_hooks.
To preserve backward compatibility of methods like imp.find_module(),
they use new variables sys.builtin_meta_path and sys.builtin_path_hooks
which are analogous to sys.meta_path and sys.path_hook but contain only
the two importer objects above.
Character encoding issues were substantial. The existing code was
somewhat inscrutable in this regard. The tests disabled in issue 1377
were re-added with more safeguards and harder tests. It is possible to
import modules with non-ascii names from non-ascii paths. Tested on
Windows XP and Linux.
Areas for discussion:
Naming: Names of the importer classes, names of variables, etc
sys: I added three variables to sys. Is there a better alternative?
ModuleInfo: The importers use a somewhat tricky way to store an open
file between calls to importer.find_module() and importer.load_module(),
so that the new code doesn't do any more system calls that the old code.
semantics: There are many import corner cases where the semantics are
unknown or unclear.
Frozen packages: the __path__ of a frozen package is a string rather
than a list, and it is possible to replace that string to change how
imports inside that package are resolved. I have attempted to keep that
functionality intact but it's not clear that it's a feature rather than
a bug.

handle realm names in single-quoted strings
In-Reply-To: <1203296568.46.0.747126970867.issue2136@psf.upfronthosting.co.za>
Message-ID: <1203296568.46.0.747126970867.issue2136@psf.upfronthosting.co.za>
New submission from Atul Varma:
This isn't necessarily a bug in Python--it's really a bug in websites
that produce what are technically malformed WWW-Authenticate headers, I
believe.
According to RFC 2617, a WWW-Authenticate header should be of the form:
WWW-Authenticate: Basic realm="Private"
However, some websites, produce the header using single-quotes:
WWW-Authenticate: Basic realm='Private'
The Firefox browser deals with this gracefully, but Python's urllib2
does not; specifically, an AbstractBasicAuthHandler does not recognize
the second type of header as an auth header at all, and as a result it's
impossible to access sites protected with such headers.
The attached patch alters the behavior of the class to deal with this
situation gracefully, and also adds a unit test to ensure that the
functionality works.
Implementation notes: This isn't the most well-engineered fix in the
world; in particular, I didn't change the regex used to parse
WWW-Authenticate headers, in part because (A) such a regex was difficult
to compose and (B) it would've been quite difficult to read, and I
didn't want to inadvertently mess up the current behavior of the code.

When comparing content with difflib, if the resulting diff covers the
last line of one or both of the inputs that that line doesn't end with
an end-of-line character(s), then the generated diff lines don't include
an EOL. Fair enough.
Naive (and I suspect typical) usage of difflib.unified_diff(...) is:
diff = ''.join(difflib.unified_diff(...))
This results in an *incorrect* unified diff for the conditions described
above.

New submission from Giampaolo Rodola':
By looking through the smtplib module code I think I've found a
potential issue in the SSLFakeFile class code since there's a while loop
which is supposed to be stopped only when the "\n" character is encountered:
def readline(self):
str = ""
chr = None
while chr != "\n":
chr = self.sslobj.read(1)
str += chr
return str
The patch in attachment just adds a break statement to prevent the while
loop to hang forever in case the "\n" character is never encountered.

New submission from STINNER Victor:
ctypes.util.find_library() fails to locate distorm64.so library
because it has no SONAME entry:
$ objdump -p -j .dynamic /usr/local/lib/libdistorm64.so
/usr/local/lib/libdistorm64.so: file format elf32-i386
(...)
Dynamic Section:
NEEDED libc.so.6
INIT 0x12f4c
FINI 0x1bf84
HASH 0xb4
(...)
Compare to libm.so:
$ objdump -p -j .dynamic /usr/lib/libm.so
/usr/lib/libm.so: file format elf32-i386
(...)
Dynamic Section:
NEEDED ld-linux.so.2
NEEDED libc.so.6
SONAME libm.so.6
INIT 0x335c
(...)
I don't know why find_library() does use objdump to get SONAME.
Workaround to find_library() "bug": _get_soname() should return
os.path.basename(f) instead of None. Is it correct?
Note: libdistorm64.so compilation is maybe broken (it's maybe not
a "real" so library), but I'm able to use it with ctypes :-)

ctypes doesn't support transparent conversion of double arguments.
Example code:
from ctypes import cdll, c_double
libm = cdll.LoadLibrary("libm.so")
sqrt = libm.sqrt
sqrt.argstype = (c_double,)
sqrt.restype = c_double
print sqrt(4.0)
I wrote a patch to fix it: see attached patch

New submission from Neal Norwitz:
Georg, I hope you don't mind me assigning this to you. Feel free to
unassign. A colleague pointed me to section 5.7 in the old ref doc:
http://docs.python.org/ref/shifting.html
It says that shifting operations lose data on overflow. This info is
outdated based on PEP 237. I suspect there may be other inaccuracies
related to int overflow. So the purpose of this bug is to point out the
specific problem as well as to log that we need to find all invalid
references to overflow.

New submission from Ernst Persson:
Nis (applications?) has a line limit in the "group" entry, so you can't
have very long lines (=many users)
The way to solve this is to put aliases in the group map, like this:
MY_GROUP::123:user1,user2
MY_GROUP::123:user3,user4
This is supported by the OS, grp.getgrall(), etc, but
nis.cat("group")
only puts the last entry into the dict it returns.
I guess the best thing if you want to return a dict is to merge the
members if both the name and gid matches.

I don't see any way in the docs to get the status of an http request, in
particular I want to know whether it's a 404. It does show up in the
guts of the library so maybe I can extract it somehow, but there should
be a simple documented way.
Also, the urllib doc says the info() method returns a mimetools.Message
instance, but what actually comes back is an httplib.HTTPMessage
instance. I guess that's a subclass, but it's confusing. The doc
should describe what actually comes back.

New submission from Virgil Dupras:
What prompted me to do these changes is that "Backward compatibility"
section for 2.1 and earlier. How long are we going to keep this? According
to svn, no commit has been made on the 2.1 branch since 2003. Is it safe
to assume no unittest change is ever going to be backported to 2.1?
Then, while I was in it, I made other changes:
- dict.has_key(key) --> key in dict
- raise Exception, args --> raise Exception(args)
- try..except KeyboardInterrupt: raise except: do_stuff() --> try..except
Exception: do_stuff()
- __metaclass__ = type --> all classes are now object subclasses
I'm not sure about the last one. Are those 2 equivalent? Is there a reason
to keep is as "__metaclass__ = type"?
regrtest passed for me.

New submission from Amaury Forgeot d'Arc:
The new doc framework highlights python code, and looks very nice.
However, some snippets are not parseable by the compiler, and are thus
left unhighlighted. For example:
http://docs.python.org/dev/whatsnew/2.6.html#the-contextlib-module
The vast majority of misses is because of lines containing "...", which
is not a valid expression (except in slices).
The attached patch tries to recognize some common patterns, and replaces
"..." by some valid identifier; "... continue processing ..." is also
transformed.
Note that the replacements are done only to get a better answer to "is
this block a python code"; pygment still works on the original string.
I checked that all new highlighted blocks are actually python snippets.
(actually, except one in configfile.rst; but others similar blocks on
the same page were already wrongly given to the python lexer)
The patch also corrects some easy syntax errors in samples.

I've been using unittest for quite a while. One thing I got tired with is
the code duplication for file management and mocking. A few months ago I

since. It works quite well.
Am I the only one to extensively use temporary files and mocking in my
tests? If not, I would suggest integrating my little subclass to
unittest.Testcase, or if people think these functionalities out-scope
unittest.TestCase, maybe we could put it in a separate unit.
Here's the unit I have here.

Message-ID: <1203620223.11.0.994407753132.issue2157@psf.upfronthosting.co.za>
New submission from wrobell:
Numeric type conversion does not always work when using SQLite module.
Let's assume schema:
create table test_num(no numeric);
Fetching a `test_num.no` table gives float by default.
Now, let's register some converter
sqlite3.register_converter('numeric', lambda d: Decimal(d))
Fetching `test_num.no` gives Decimal.
But change `test_num.no` type to `numeric(10, 2)`. Float is returned.
This can be fixed by
sqlite3.register_converter('numeric(10,', lambda d: Decimal(d))
But above will fail for `test_num.no: numeric(10,2)', which works in
case of
sqlite3.register_converter('numeric(10,2)', lambda d: Decimal(d))
SQLite module's cursor object type cast mechanism breaks declared
type after first space {i.e. "numeric(10, 2)" -> "numeric(10,"} and
then looks up registered type converter using the first "word".
The simple fix for above could be to perform the break after space
or "(" character. Patch attached.

performance prohibitive
In-Reply-To: <1203640875.82.0.736964888757.issue2159@psf.upfronthosting.co.za>
Message-ID: <1203640875.82.0.736964888757.issue2159@psf.upfronthosting.co.za>
New submission from johansen:
We've been using Python 2.4 to build the new package management software
for OpenSolaris. We use a ndbm database to hold keywords about
packages, and found that each time we added a new OpenSolaris build to
our package repository, the time to import would increase by about 1/3
of the previous time.
It turns out that we were continually invoking a function in the
dbmmodule that walked the entire database every time the function was
called.
Looking at dbmmodule.c, the source for dbm.so, is instructive:
This is dbm_length, the function that we're _always_ calling.
static int
dbm_length(dbmobject *dp)
{
if (dp->di_dbm == NULL) {
PyErr_SetString(DbmError, "DBM object has already been
closed");
return -1;
}
if ( dp->di_size < 0 ) {
datum key;
int size;
size = 0;
for ( key=dbm_firstkey(dp->di_dbm); key.dptr;
key = dbm_nextkey(dp->di_dbm))
size++;
dp->di_size = size;
}
return dp->di_size;
}
It's a knock-off of function shown in ndbm(3C) that traverses the
database. It looks like this function walks every record in the
database, and then returns that as its size.
Further examination of dbmmodule shows that dbm_length has been assigned
as the function for the inquiry operator:
static PyMappingMethods dbm_as_mapping = {
(inquiry)dbm_length, /*mp_length*/
(binaryfunc)dbm_subscript, /*mp_subscript*/
(objobjargproc)dbm_ass_sub, /*mp_ass_subscript*/
};
It looks like dbm_length stashes the size of the database, so it doesn't
always have to traverse it. However, further examination of the source
shows that an insertion doesn't update the di_size counter. Worse yet,
an update or a delete will cause the counter to be set to -1. This
means that the next call to dbm_length will have to walk the entire
database all over again. Ick.
One of the problem parts of the code is this line in catalog.py:
update_searchdb():
if fmri_list:
if not self.searchdb:
self.searchdb = \
dbm.open(self.searchdb_file, "c")
This if not triggers the PyObject_IsTrue that invokes the inquiry operator
for the dbm module. Every time we run this code, we're going to walk
the entire database. By changing this to:
if fmri_list:
if self.searchdb is None:
self.searchdb = \
dbm.open(self.searchdb_file, "c")
We were able to work around the problem by using the is None check,
instead of if not self.searchdb; however, this seems like it is really a
problem with the dbmmodule and should ultimately be resolved there.

New submission from Guido van Rossum:
I find that test_socket fails regularly (but not always) when run via
"regrtest.py -uall". The message is always "socket is not connected" but
it's unclear from which test it comes -- all I know is that it comes
from tearDown() on line 123.
(This may be a problem with 2.6 as well -- or not.)

Attached patch improves pydoc UserDict presentation.
One of the problems with the current documentation in comments is that
order of methods is not preserved and thus the method level comments in
DictMixin implementation are meaningless in pydoc. (In any case the
comments are not accurate even in the source file.)
If this patch is accepted in principle, the original level comments
should be removed. I am leaving them intact to simplify the review.

New submission from Michael Otteneder:
Python seems to fail silently when LANG enviroment variable is set to a
bad value. In Mac OS X Leopard it is set too UTF-8 for instance which
does not seem to be valid. Python fails building the modules during make
and the generated python.exe is unable to output anything. Setting the
LANG variable to C or some other valid value fixes the problem. But I
suppose python should fail more verbose in case of a bad locale,or maybe
it should fallback to a standard locale.

Message-ID: <1203861152.32.0.18277152276.issue2174@psf.upfronthosting.co.za>
New submission from Yitz Gale:
In the documentation for xml.sax.xmlreader.InputSource objects
(section 8.12.4 of the Library Reference) we find that
users of InputSource objects should use the following
sequence to get their input data:
1. If the InputSource has a character stream, use that.
2. Otherwise, if the InputSource has a byte stream, use that.
3. Otherwise, open a URI connection to the system ID.
The parse() method of IncrementalParser skips step 1.
In addition, we need to add a method
getSourceEncoding() to the XMLReader interface;
if non-null, it will indicate to the parser that
the input is a byte stream in the given encoding.
The documentation should indicate what the parser
should do if the XML itself announces that its
encoding is something else. I propose that the parser should
be required to raise an error in that case.
See also #1483.

New submission from Yitz Gale:
The expat sax parser in xml.sax.expatreader
does not fully support the InputSource protocol
in xml.sax.xmlreader. It only accepts
byte streams. It ignores the encoding
indicated in the InputStream object and
only uses the encoding read from
the XML or defaults to UTF-8.
Rather than silently doing the wrong thing,
it should raise an error when fed a character stream,
or when given an encoding, via the InputSource
interface.
And most importantly, these limitations should be mentioned
in the documentation.

try/finally

Message-ID: <1203894641.18.0.492382147443.issue2179@psf.upfronthosting.co.za>
New submission from Jeffrey Yasskin:
Currently, 'with' costs about .2us over try/finally:
$ ./python.exe -m timeit -s 'import thread; lock =
thread.allocate_lock()' 'lock.acquire()' 'try: pass' 'finally:
lock.release()'
1000000 loops, best of 3: 0.617 usec per loop
$ ./python.exe -m timeit -s 'import thread; lock =
thread.allocate_lock()' 'with lock: pass'
1000000 loops, best of 3: 0.774 usec per loop
Since it's doing the same thing (and calling the same C functions to do
the lock manipulation), it shouldn't take more time. The bytecodes
associated with the two options look like:
2) with lock:
3) pass
2 0 LOAD_GLOBAL 0 (lock)
3 DUP_TOP
4 LOAD_ATTR 1 (__exit__)
7 STORE_FAST 0 (_[1])
10 LOAD_ATTR 2 (__enter__)
13 CALL_FUNCTION 0
16 POP_TOP
17 SETUP_FINALLY 4 (to 24)
3 20 POP_BLOCK
21 LOAD_CONST 0 (None)
>> 24 LOAD_FAST 0 (_[1])
27 DELETE_FAST 0 (_[1])
30 WITH_CLEANUP
31 END_FINALLY
32 LOAD_CONST 0 (None)
35 RETURN_VALUE
6) lock.acquire()
7) try:
8) pass
9) finally:
10) lock.release()
6 0 LOAD_GLOBAL 0 (lock)
3 LOAD_ATTR 1 (acquire)
6 CALL_FUNCTION 0
9 POP_TOP
7 10 SETUP_FINALLY 4 (to 17)
8 13 POP_BLOCK
14 LOAD_CONST 0 (None)
10 >> 17 LOAD_GLOBAL 0 (lock)
20 LOAD_ATTR 2 (release)
23 CALL_FUNCTION 0
26 POP_TOP
27 END_FINALLY
28 LOAD_CONST 0 (None)
31 RETURN_VALUE
The major difference I see is the extra local variable (_[1]) used by
with. It looks like the compiler ought to be able to save that on the
stack instead, and save 3 opcodes. Neal Norwitz suggested that, if that
optimization is impossible, WITH_CLEANUP could be modified to take the
variable as a parameter, which would let it absorb the LOAD_FAST and
DELETE_FAST instructions.
I've added everyone on the previous bug to the nosy list. Sorry if you
don't care. :)

Subject: [New-bugs-announce] [issue2181] optimize out local variables at end
of function
In-Reply-To: <1203904814.51.0.0269762586023.issue2181@psf.upfronthosting.co.za>
Message-ID: <1203904814.51.0.0269762586023.issue2181@psf.upfronthosting.co.za>
New submission from Neal Norwitz:
This patch optimizes code like:
x = any_expression
return x
to:
return any_expression
Currently it only optimizes out the local variable if there is a return
because it can't determine if this is the last use of the variable or not.
This shouldn't change behaviour under normal circumstances, but would
change behaviour with a debugger. Perhaps this optimization should only
be performed if -O is passed on the command line?
This optimization saves two trips around the eval loop (STORE_FAST and
LOAD_FAST) and 6 bytes in the byte code.

Subject: [New-bugs-announce] [issue2183] optimize list comprehensions
In-Reply-To: <1203906152.35.0.945763555719.issue2183@psf.upfronthosting.co.za>
Message-ID: <1203906152.35.0.945763555719.issue2183@psf.upfronthosting.co.za>
New submission from Neal Norwitz:
Optimize list comprehensions by using the list on the stack, rather than
storing in a (local/global) variable. This reduces the size of the
stack by one pointer, reduces the bytecode size by 8, and reduces the
iterations in the eval loop by 2 + # of iterations to create the new
list. It also eliminates internal variables in varnames.
List comps in module/class scope execute faster by avoiding more costly
dict lookups in globals.
For this source code:
def f(): return [x for x in s]
Byte code before change:
1 0 BUILD_LIST 0
3 DUP_TOP
4 STORE_FAST 0 (_[1])
7 LOAD_GLOBAL 1 (s)
10 GET_ITER
>> 11 FOR_ITER 13 (to 27)
14 STORE_FAST 1 (x)
17 LOAD_FAST 0 (_[1])
20 LOAD_FAST 1 (x)
23 LIST_APPEND
24 JUMP_ABSOLUTE 11
>> 27 DELETE_FAST 0 (_[1])
30 RETURN_VALUE
New byte code:
1 0 BUILD_LIST 0
3 LOAD_GLOBAL 0 (s)
6 GET_ITER
>> 7 FOR_ITER 12 (to 22)
10 STORE_FAST 0 (x)
13 LOAD_FAST 0 (x)
16 LIST_APPEND 2
19 JUMP_ABSOLUTE 7
>> 22 RETURN_VALUE
DUP_TOP/STORE_FAST are eliminated before the loop. One LOAD_FAST is
eliminated inside the loop. LIST_APPEND is changed to reference the
value on the stack. Is it a problem to change the opcode of LIST_APPEND?
This might make debugging harder. I'm not sure how debuggers work with
list comps.
A similar optimization could probably be done to eliminate all uses of
the temporary variables (WITH_CLEANUP at least).
This patch still needs to update docs and the compiler package
implemented in Python.

Subject: [New-bugs-announce] [issue2184] Speed up Thread.start()
In-Reply-To: <1203906623.93.0.917189380676.issue2184@psf.upfronthosting.co.za>
Message-ID: <1203906623.93.0.917189380676.issue2184@psf.upfronthosting.co.za>
New submission from Jeffrey Yasskin:
Thread.start() used sleep(0.000001) to make sure it didn't return before
the new thread had started. At least on my MacBook Pro, that wound up
sleeping for a full 10ms (probably 1 jiffy). By using an Event instead,
we can be absolutely certain that the thread has started, and return
more quickly (217us).
Before:
$ ./python.exe -m timeit -s 'from threading import Thread' 't =
Thread(); t.start(); t.join()'
100 loops, best of 3: 10.3 msec per loop
$ ./python.exe -m timeit -s 'from threading import Thread; t =
Thread()' 't.isAlive()'
1000000 loops, best of 3: 0.47 usec per loop
After:
$ ./python.exe -m timeit -s 'from threading import Thread' 't =
Thread(); t.start(); t.join()'
1000 loops, best of 3: 217 usec per loop
$ ./python.exe -m timeit -s 'from threading import Thread; t =
Thread()' 't.isAlive()'
1000000 loops, best of 3: 0.86 usec per loop
To be fair, the 10ms isn't CPU time, and other threads including the
spawned one get to run during it. There are also some slightly more
complicated ways to get back the .4us in isAlive() if we want.

Message-ID: <1203907300.87.0.511382024936.issue2185@psf.upfronthosting.co.za>
New submission from Neal Norwitz:
Various bits are often duplicated in code objects. For example,
sometimes names and varnames are equal. In this case, we don't need two
objects since they are both const. This patch implements a trivial fix
for this case. However, there are more cases. We should profile where
the memory is being used and do simple/cheap consolidations where
possible. Another example would be a 1-element tuple containing:
(None,) for consts.
Some (all?) of these sorts of optimizations should probably be done in
the code object itself.

New submission from anatoly techtonik:
Patch documents that empty dictionary is used to make ProxyHandler()
with disabled proxy autodetection. Empty constructor doesn't give the
desired effect.
P.S. An ideal approach would be, of course, to change the API. Even
though it can be changed drastically the simple hack would look like:
class ProxyHandler([proxies][, autodetect=False])
Seems like it is better to leave API for Py3K refactoring issue, like #1333

File "/usr/lib/python2.5/urllib.py", line 1205, in quote
res = map(safe_map.__getitem__, s)
KeyError: ''
I think this is a weird error message to throw. quote() is obviously
assuming that the param passed is a one-character string iterator or
something. It should either accept just strings or come up with a better
error message when confronted with an iterator element that is not a
one-character string, IMO.

do not have Microsoft Visual Studio installed on my system but do have
the .NET framework 1.1 installed. The reason code in the pop up says
either the IDLE cannot start a subprocess or a firewall is blocking the
connection. Is it necessary that the anitvirus/firewall software needs
to be disabled before installing Python 3.0 or is it the case as
mentioned in the http://www.python.org/download/releases/3.0/ "Read
this first" section i.e. python30.dll cannot be installed in system32

New submission from Gawain Bolton:
The urlparse() function in urlparse module does not handle URLs without
an explicit scheme and with port numbers.
The following works as expected:
>>> urlparse.urlparse('foo.bar.com','http').scheme
'http'
But if the URL has a port number then the scheme is wrong:
>>> urlparse.urlparse('foo.bar.com:8080','http').scheme
'foo.bar.com'
I have read RFC 1808 and its description of the parsing of the scheme
also has this bug. From what I can figure, the parsing algorithm needs
to search for the scheme before the substring "://" and not just ":".

New submission from Benjamin Peterson:
hasattr currently returns False when any exception happens in getattr. I
see that this tracker I previous patches trying to fix this issue, but
they were rejected because they only tried to catch attribute errors. My
patch only propagates SystemExit and KeyboardInterrupt exceptions.

The advantage is more compact and faster bytecode and uniform treatment

New submission from Stephan R.A. Deibel:
The algorithm in code_hash() in codeobject.c can return the same hash
value for different code objects.
Presumably distinct code objects should be very unlikely to have the
same hash value. This bug affected our debugger before we worked around
it, and it could affect other things like profilers.
Adding the co_filename to the hash would be one way to fix this but I'm
not sure if that was purposely avoided in this code?

New submission from PyScripter:
cPickle has problems loading instances of gtk gobject.GEnum classes.
gobject.GEnum is a subclass of int. On the other hand pickle handles
those classes correctly. Since cPickle is meant to be a faster version
of pickle this needs to be consider a bug.
To test run the following script:
import gtk
##import pickle
import cPickle as pickle
simple_types = (
bool,
int,
long,
float,
complex,
basestring,
type(None),
)
d = vars(gtk)
for (i,j) in d.iteritems():
if isinstance(j, simple_types):
try:
s = pickle.dumps(j, pickle.HIGHEST_PROTOCOL)
obj = pickle.loads(s)
except (ValueError, TypeError):
print j, type(j)
If you replace cPickle with pickle then the script runs fine.

New submission from Brendan W. McAdams:
URLLIB2 seems to have issues attempting to digest authenticate against a
Windows-based IIS 6.x server. The IIS server requests MD5-sess support,
and URLLIB2 throws an exception that ... far from explains this:

UnboundLocalError: local variable 'H' referenced before assignment
The offending code is urllib2.py line 972:
def get_algorithm_impls(self, algorithm):
# lambdas assume digest modules are imported at the top level
if algorithm == 'MD5':
H = lambda x: hashlib.md5(x).hexdigest()
elif algorithm == 'SHA':
H = lambda x: hashlib.sha1(x).hexdigest()
# XXX MD5-sess
KD = lambda s, d: H("%s:%s" % (s, d))
return H, KD
I'm not sure what's meant by the # XXX MD5-sess comment there... But
what ends up happening is that MD5-sess matches neither the if or the
elif, and when return attempts to return, H is undefined.
This could be easily patched, but support for MD5-sess would be great as
well.
In my estimation, at the least, urllib2 shouldn't crap out in such an
obscure way when encountering an unsupported algorithm.
I'd suggest changing line 970 (The # XXX MD5-sess line) to:
raise Exception, "Unsupported Digest Authentication Algorithm '%s'" %
(algorithm)

New submission from Raghuram Devarakonda:
ConfigParser.add_section() raises DuplicateSectionError if add_section()
is called with the name of a section that is already present. How ever,
if a section is present multiple times in a file, readfp() does not
raise any exception. Instead, the sections are "combined" with values in
latter sections overwriting previous values (if any). This should be
documented in readfp(). I tried few alternatives but the sentences don't
look right. I am creating the issue in the hope that some one else may
give it a try while I continue to come up with a doc patch.

New submission from Tim Golden:
When pygments is not available to the sphinx build environment, the
PygmentsBridge in the highlighting.py module raises an exception in the
unhighlighted function. This function attempts to use the .dest
attribute which isn't set in the __init__ if the pygments import has failed.
The attached patch moves the .dest setting up so it is always set
regardless of the presence of pygments. I don't know if it's a complete
solution, but the help, htmlhelp and web all build.

works, but is ugly).

Message-ID: <1204286639.84.0.689580155696.issue2210@psf.upfronthosting.co.za>
New submission from R?diger Kupper:
When one module of a package imports another module of the same package,
the second module will not only be introduced in the namespace of the
importing module, but also in the namespace of the enclosing package.
I.e., the module will be introduced as variable
<packagename>.<secondmodulename>. If the package namespace contained a
variable of this name before the import, it will be overwritten by the
new value.
For the user, import statements should act like assignments to the local
namespace. They should never add names to an enclosing namespace. (At
least this is what all documentation and tutorials tell the user.)
Below follows a detailed example for the problem.
Say I have a package named 'pack'. Apart from the '__init__.py' file the
directory contains two modules 'x.py' and 'y.py':
pack/
__init__.py
x.py
y.py
The files have the following contents:
==== __init__.py ====
import x
=====================
==== x.py ===========
import y
=====================
==== y.py ===========
pass
=====================
I then do
>>> import pack
This
(1) introduces variable 'x' bound to <module 'pack.x'>
in pack's namespace (expected)
(2) introduces variable 'q' bound to <module 'pack.y'>
in x's namespace (expected)
but also
(3) introduces variable 'y' bound to <module 'pack.y'>
in pack's namespace (*totally unexpected*)
The problem is so bad as to even overwrite any variable 'y' that
might have existed in pack's namespace before the import.
I created verbose versions of the three files above to illustrate
what happens (see below.) They do exactly the same as above, but
print out what they do. This is the output:
---------snip-----------
>>> import pack
pack: Here is pack.
pack: I now assign y='hello'.
pack: My y is now: 'hello'
pack: I now 'import x' which in turn does 'import y as q'.
x: Here is x.
x: I now 'import y as q'.
y: Here is y.
pack: My y is now: <module 'pack.y' from 'pack/y.pyc'>
pack: Why?
--------snip-------------
I know that any import creates an entry in sys.modules. So 'pack',
'pack.x' and 'pack.y' get created in sys.modules. That's fine.
Apart from that, an import statement should act equivalent to an
assignment: it should introduce entries to the local namespace of the
module it appears in. The 'import y as q' appears in x.py, so it
should add entries to x's namespace *only*.
But why is variable 'y' in pack's namespace overwritten by the
import in x?
P.S.: These are the files that produce the verbose output. They can be
found in the tgz file attached to this issue.
==== __init__.py ====
print "pack: Here is pack."
print "pack: I now assign y='hello'."
y="hello"
print "pack: My y is now:", repr(y)
print "pack: I now 'import x' which in turn does 'import y as q'."
import x
print "pack: My y is now:", repr(y)
print "pack: Why?"
=====================
==== x.py ===========
print ' x: Here is x.'
print " x: I now 'import y as q'."
import y as q
=====================
==== y.py ===========
print ' y: Here is y.'
=====================

Subject: [New-bugs-announce] [issue2211] Cookie.Morsel interface needs update
In-Reply-To: <1204315259.46.0.997806067058.issue2211@psf.upfronthosting.co.za>
Message-ID: <1204315259.46.0.997806067058.issue2211@psf.upfronthosting.co.za>
New submission from Jamie Bliss:
Cookie.Morsel lacks in properly overloading dict methods, amongst other
things:
* .__eq__() does not take .key and .value into account
* .copy() returns a dict, not a Morsel
* .update() allows invalid attributes in, eg
Morsel().update({'eggs':'spam'}) works but Morsel()['eggs'] = 'spam' fails
* .__len__() includes unset keys (why does it set them to an empty string?)
* .__repr__() doesn't print out attributes (path, comment, etc)
* Handling of unicode is fuzzy at best: try Morsel().set(u'eggs\u00bf',
u'\u00f1', u'\00f1'.encode('utf-8'))
* Specifying the idmap and translate function in .set() seems wrong
* Setting .key doesn't check against invalid keys (eg, reserved names)
* The entire Morsel class is undocumented
* There is no way to automatically sync .value and .coded_value

Subject: [New-bugs-announce] [issue2212] Cookie.BaseCookie has ambiguous
unicode handling
In-Reply-To: <1204315669.5.0.476777122389.issue2212@psf.upfronthosting.co.za>

New submission from Jamie Bliss:
The primary offender is in BaseCookie.load(), which uses the test:
type(rawdata) == type("")
which should be:
isinstance(rawdata, basestring)
