Subject: [New-bugs-announce] [issue1531] tarfile.open(fileobj=f) and bad
metadata of the first file within the archive
Message-ID: <1196463606.39.0.826959093922.issue1531@psf.upfronthosting.co.za>
New submission from George Notaras:
Assume the following situation:
- a healthy and uncompressed tar file: a.tar
- the metadata of the 1st and second files within the archive start at
positions 0 and 756 (realistic example values)
I partially damage 200 bytes of metadata (byte range 0-500) of the first
archived file:
f = open("a.tar", "rb+")
f.seek(100)
f.write("0"*200)
Now, I seek to the start of the 2nd archived file's metadata:
f.seek(756)
And I try to open the tar archive using tarfile.open() passing the
previous fileobject to it.
import tarfile
f_tar = tarfile.open(fileobj=f)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "tarfile.py", line 1143, in open
raise ReadError("file could not be opened successfully")
tarfile.ReadError: file could not be opened successfully
Wouldn't the expected behaviour be to successfully open the tar archive
at offset 756?
It seems that tarfile.open(fileobj=f) seeks to position 0 of the
fileobject f, fails to read the 1st archived file's metadata and throws
an exception.

Message-ID: <1196468890.07.0.55666875231.issue1533@psf.upfronthosting.co.za>
New submission from Robert Bradshaw:
Range accepts arguments coerce-able into ints via __int__, but rejects
arguments coerce-able into longs but to large to fit into an int.
The problem is in handle_range_longs in bltinmodule.c:1527-1541. If they
type is not an int or long, it should try to make it so before failing
(for consistency with smaller values at least).
Attached is a file that reproduces this bug.

Message-ID: <1196535861.35.0.87845321139.issue1536@psf.upfronthosting.co.za>
New submission from Alexandre Vassalotti:
The current documentation for the pickle module (and related modules) is
outdated and should be updated. For example, the section "Pickling and
unpickling extension types" [1] is not only confusing, but outright
wrong. For Python 2.6, the documentation of cPickle should be updated to
reflect the differences between the cPickle and pickle.py modules. It
would be also be appropriate to note that cPickle is pending removal and
should not be used anymore.

Message-ID: <1196581862.98.0.506596232577.issue1538@psf.upfronthosting.co.za>
New submission from Skip Montanaro:
The topic of avoiding string copies in certain string methods came up in
the
ChiPy list:
http://mail.python.org/pipermail/chicago/2007-December/002975.html.
The attached patch modifies the split and rsplit implementations to
avoid
making a copy of self when the split fails to find anything to split on:
>>> s = "abc def"
>>> x = s.split(';')
>>> x[0] is s
True
>>> y = s.rsplit('-')
>>> y[0] is s
True
>>> t = "abcdef"
>>> x = t.split()
>>> x[0] is t
True
>>> y = t.rsplit()
>>> y[0] is t
True
All tests pass. Given that this is just a small optimization I
don't believe any changes to the docs or the existing tests are
necessary.

Subject: [New-bugs-announce] [issue1541] Bad OOB data management when using
asyncore with select.poll()
Message-ID: <1196618056.9.0.300104478176.issue1541@psf.upfronthosting.co.za>
New submission from billiejoex:
asyncore's module readwrite() function, used when invoking
asyncore.loop(use_poll=1), erroneously calls handle_read_event() when
receiving OOB (Out Of Band) data. handle_expt_event() should be called
instead.
The patch in attachment does that.
In addition I strongly think that POLLERR, POLLHUP and POLLNVAL events
handling is incorrect too.
As far as I read from here:
http://www.squarebox.co.uk/cgi-squarebox/manServer/usr/share/man/man0p/poll.h.0p
...they refers to the following events:
POLLERR An error has occurred (revents only).
POLLHUP Device has been disconnected ( revents only).
POLLNVAL Invalid fd member (revents only).
They are actually associated to handle_expt_event() and this is
incorrect since it should be called only when receiving OOB data.
if flags & (select.POLLERR | select.POLLHUP | select.POLLNVAL):
obj.handle_expt_event()
I'm not sure what should be called instead, if handle_read_event or
handle_read or handle_error.
I tried to take a look at how Twisted manages the thing but it seems
that OOB is not even supported.
Maybe someone with more experience in using select.poll could clarify that.

New submission from Christian Heimes:
Hello Martin!
How do you like the idea to ship the 32bit and 64bit libs with the MSI
installer? The 64bit libs could be stored in libs64 while the 32bit libs
stay in libs.
I'm working on a task for the GHOP to add cross compiling support to
msvc9compiler. The extra libs are needed to compile 64bit libs on Win32
or the other way around.

New submission from Isaul Vargas:
Problem:
I'd like to run Python 32 bit (for compatibility with extensions) and
Python 64 bit on Vista (for speed and 64 bit apps) on one machine.
However Vista has an 'improved' installer for MSI apps, where if I
install Python 64 bit first, I can't install Python 32 bit afterwards,
because Vista's Window Installer says 'Another version of this product
is already installed. Installation of this version cannot continue. To
configure or remove the existing version of this product, use
Add/Remove Programs on the Control Panel'
The converse of this is true, if you install Python 64 bit first, you
cannot install Python 32 bit afterwards.
The MSI packaging needs to be updated.

New submission from Tim Golden:
One typo refers to "from __future__ import generators" in the context of
the with statement.
Later what appears to be an incomplete sentence giving an example of the
__dir__ method.
The patch attached is against r59286 of doc/whatsnew/2.6.rst

and rich comparison operators
Message-ID: <1196689891.72.0.237226656542.issue1549@psf.upfronthosting.co.za>
New submission from Thomas Herve:
A new behavior was introduced in r59106 in python trunk, which look
suspicious to me. Basically, every time a class defines a comparison
operator, it's __hash__ method is defined to None. The simple following
example shows it:
>>> class A(object):
... def __init__(self, b):
... self.b = b
... def __cmp__(self, other):
... if not isinstance(other, A):
... return -1
... return cmp(self.b, other.b)
...
>>> hash(A(2))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'NoneType' object is not callable
The problematic change is here:
http://svn.python.org/view/python/trunk/Objects/typeobject.c?rev=59106&r1=58032&r2=59106
And mainly the overrides_hash call in inherit_slots.
FWIW, I've encounter the problem because zope.interface is now usable on
trunk.

Subject: [New-bugs-announce] [issue1550] help('modules') broken by several
3rd party libraries (svn patch attached)
Message-ID: <1196699649.3.0.798271270482.issue1550@psf.upfronthosting.co.za>
New submission from Ben Hayden:
Instead of listing installed modules, help('modules') prints a "please
wait" message, then a traceback noting that a module raised an exception
during import, then nothing else.
This happens in 2.5 and 2.6a0, but not in 2.4, which apparently doesn't
__import__() EVERY module.
Tested only on Gentoo Linux 2.6.19, but same behavior is probable on
other platforms because pydoc and pkgutil are written in cross-platform
Python.
Prominent 3rd party libraries that break help('modules') include Django,
Pyglet, wxPython, SymPy, and Pypy. Arguably, the bug is in those
libraries, but they have good reasons for their behavior. Also, the Unix
philosophy of forgiving input is a good one. Also, __import__()ing every
module takes a significant run-time hit, especially if libraries compute
eg. configuration.
The patch utilizes a pre-existing hook in pkgutil to simply quietly add
the module to the output. (Long live lambda.)

terminate (probably because the stdout buffersize is too small). This
causes the win64-buildbot to hang.

Subject: [New-bugs-announce] [issue1560] PATCH: Attribute lookup caching
Message-ID: <1196888425.03.0.368488878757.issue1560@psf.upfronthosting.co.za>
New submission from Neil Toronto:
I've attached a patch to accelerate type and instance lookups using a
specialized cache. It includes a benchmarking script (fastattr_test.py)
that tests both successful and failing lookups on list, dict and tuple,
and a simple, deep hierarchy. Benchmark results are here:
http://spreadsheets.google.com/ccc?key=pHIJrYc_pnIUpTm6QSG2gZg&hl=en_US
Everything tested in fastattr_test.py is faster except list.__init__ and
list().__init__ (and I haven't got a clue why, so some pointers would be
nice). Pybench is faster overall. TryRaiseExcept is faster for some
non-obvious reason. CreateNewInstances is a little slower, which I'll
discuss in a bit. Setting type attributes is slower, but I haven't
benchmarked that yet. It may not happen often enough that we care as
long as it's not noticeably slow in general usage.
In benchmarks the patch does a little slower, it may be in part because
I removed a manually inlined _PyType_Lookup from
PyObject_GenericGetAttr. Something like it can be put back if it needs
to be.
It works in a fairly obvious way. Every type has a tp_cache, which is a
custom dict type that caches the first value in a type dict in the MRO
for a given name. Lazy cached lookups are done via
_PyType_CachingLookup, which is a drop-in replacement for
_PyType_Lookup. The only way to set an attribute on a type is via its
setattr, so type's setattr notifies subclasses to invalidate specific
cache entries.
The cache dict is custom for two reasons:
1. The regular dict is a little slower because it's more general. The
custom dict is restricted to string-exact keys (types fall back to no
caching if this constraint is violated). Because it's internal to
typeobject.c, it's safe for lookups to return entry pointers rather than
values, so lookups only have to be done once, even on cache misses.
2. Caching missing attributes is crucial for speed on instance attribute
lookups. Both type and metatype instances check all the way through the
MRO for a descriptor before even trying to find an attribute. It's
usually missing. Having to go through the cache machinery to find a
missing attribute for every attribute lookup is expensive. However,
storing all missing attribute queries in the cache is bad - it can grow
unboundedly through hasattr(inst, <random name>) calls.
What's needed is a dict that knows that some of its entries are
transient and doesn't copy them over on resize. It wasn't clear how to
implement that efficiently with a regular dict (I suspect it's not
possible), so I created a new dict type that considers entries transient
(meaning the attribute is missing) when me_value == NULL.
This is also very good for failing hasattr(...) calls and
try...inst.method()...except style duck typing.
Now, about the CreateNewInstances benchmark. It creates three classes
with __init__ methods that assign a few attributes. The missing
descriptors are cached, and then the cache is resized, which clears the
cached missing descriptors. Increasing the minimum cache size from 4 to
8 clears up the problem. However, for any class, SOME minimum cache size
will properly cache missing descriptors and some other one won't.
I have some solutions for this floating around in my head, which I'll
try shortly. (One idea is for missing attributes, if they're not missing
on the *instance*, to be permanent in the cache.) But I'd like to get
this patch off my hard drive and into other people's hands for testing,
poking, prodding, and getting feedback on what's going right and what's not.

New submission from Amaury Forgeot d'Arc:
test_mailbox keeps failing on Windows, due to line-ending issues.
Difficult things began when the files started to open in text mode.
Trying to list problems:
- mailbox.py works with differences of tell() results, and uses this to
as an argument to read(). This is wrong for two reasons: tell() returns
an offset in the file, and mixes this with the codec status.
- _PartialFile (a narrowed view of a file) does not work, for the same
kinds of reasons.

Message-ID: <1196950417.92.0.75484555157.issue1562@psf.upfronthosting.co.za>
New submission from poelzi:
The Decimal class doesn't use lookups through self to construct results
in functions like __add__ to generate the resulting object. This makes
subclassing Decimal more or less senseless since all methods have to be
wrapped instead of overriding the __new__ and __init__ methods, which
could be enough for immutable type.
Currently I'm implementing a Money class which is more or less a
Decimal with addition currency information. Because resulting Types
generated with something like return Decimal(something) instead of
self.__new__(...)

typedef struct {
PyObject_HEAD
SOCKET_T sock_fd; /* Socket file descriptor */
int sock_family; /* Address family, e.g., AF_INET */
int sock_type; /* Socket type, e.g., SOCK_STREAM */

errno, returns NULL and
sets a Python exception */
double sock_timeout; /* Operation timeout in seconds;
0.0 means non-blocking */
} PySocketSockObject;
The PyTypeObject sock_type doesn't have support for cyclic GC. Shouldn't
types that can contain a PyObject* use GC?

Message-ID: <1197033844.22.0.578664150346.issue1567@psf.upfronthosting.co.za>
New submission from Christian Heimes:
The patch adds a new API method _PyImport_ImportModuleNoLock(const char
*name). It works mostly like PyImport_ImportModule except it does not
block. It tries to fetch the module from sys.modules first and falls
back to PyImport_ImportModule UNLESS the import lock is held by another
thread.
It fixes several issues related to dead locks when a thread uses a
function that imports a module but another thread holds the lock. It
doesn't require static caching of modules.
The patch is against py3k but I can backport it to 2.6.

Subject: [New-bugs-announce] [issue1568] PATCH: Armin's attribute lookup
caching for 3.0
Message-ID: <1197034097.09.0.871896219058.issue1568@psf.upfronthosting.co.za>
New submission from Neil Toronto:
This is a half-port of the patches in #1685986 and #1700288 to Python
3.0. Speedups are about the same as in those patches applied to their
respective Python versions for minibenchmarks (included in the patch as
fastattr_test_py3k.py): 5%-30% or more depending on how deep the class
hierarchy is. Pybench takes 4% less time on my system, and pystone takes
6% less time.
(Pybench would do better, but SpecialClassAttribute runs long and spends
half its time setting class attributes.)
The main difference between this and the previous patches is that 3.0's
simplifications allow a smaller footprint and make it easier to analyze
its correctness. Specifically, the fact that every object in the MRO
must be a type allows us to assume that every attribute lookup is
cacheable, and allows integration into the update_subclasses mechanism
when attributes are set. The lack of compiled extension modules means
there is no flag to check to see whether a type object supports caching.

The "common stumbling blocks" section reads:
* Code that unconditionally strips the trailing ``L`` from the

This explains a problem and a fix without any reason (one has to guess
it from context).
It should first mention that the 'L' is no longer displayed.

Message-ID: <1197242604.93.0.919654384861.issue1577@psf.upfronthosting.co.za>
New submission from Ingemar Nilsson:
If you use shutil.move(src, dst) to move a file src to a directory dst,
the file will not be renamed into the dst directory, but rather
copied-then-removed, even if src and dst is on the same filesystem.
There are several ways to fix this:
* (The easiest) Fix the documentation for shutil.move() so that this is
mentioned.
* Fix shutil.move() so that it rename a file into a new directory.
* Change os.rename() to accept a directory as a destination for a file.
The reason for this problem is that shutil.move() tries to use
os.rename(), but fails since the destination is a directory. It then
proceeds to the copy-then-remove method, even though the documentation
gives the impression that this only happens when src and dst are on
different filesystems.

Message-ID: <1197300194.46.0.863908405505.issue1579@psf.upfronthosting.co.za>
New submission from Kylotan:
The documentation for the logging module is quite confusing, and (I am
told) seems to assume prior experience with the log4j utility or similar.
In particular:
- the front page has a rather confusing example of the named hierarchy
system, which might mislead the reader by making them think it's about
file types (perhaps for log output) rather than just arbitrary naming
conventions.
- section 14.5.3 attempts to explain this hierarchy, but does so via an
example for something else (ie. showing logging to multiple
destinations), and is just a large code-dump, mixing several concepts in
one example.
All in all, it could just do with being a lot more explicit about how
the naming convention and the hierarchy works, how each logger relates
to children/parents, and having a more transparent example on the first
page.

Message-ID: <1197314007.06.0.227642647262.issue1580@psf.upfronthosting.co.za>
New submission from Noam Raphael:
The current float repr() always calculates the 17 first digits of the
decimal representation of a float, and displays all of them (discarding
trailing zeros). This is a simple method for making sure that
eval(repr(f)) == f. However, many times it results in a long string,
where a shorter string would have sufficed. For example, currently
repr(1.1) is '1.1000000000000001', where obviously '1.1' would have been
good enough, and much easier to read.
This patch implements an algorithm for finding the shortest string that
will evaluate to the right number. It is based on the code from
http://www.cs.indiana.edu/~burger/fp/index.html, and also on the
floating-point formatting function of TCL, Tcl_PrintDouble.
The patch also adds a test case, which takes a long list of floating
point numbers, created especially for testing binary to decimal
conversion, and makes sure that eval(repr(f)) == f. See
floating_points.txt for the source of the list.

New submission from Andreas Hasenack:
I was trying to use xmlrpclib.ServerProxy() with https and client
certificate validation (I know httplib doesn't do server certificate
validation yet). I found no way to pass on host/uri as a
(host,x509_dict) tuple as the connection methods support, so I came up
with this patch.

New submission from C. E. Ball:
On OS X, I wanted to build my own copy of Python that used my own copy
of Tkinter (built for X11).
To do this, I passed "LDFLAGS=-rpath,/path/to/lib" to configure so that
Python could find my specific lib files, but I also had to edit Python's
setup.py so that detect_tkinter() would not do anything special for Darwin:
$ diff setup.py original_setup.py
1199c1199
< if 0 and (platform == 'darwin' and
---
> if (platform == 'darwin' and
I did this based on a post by Ronald Oussoren to the Python-SIG Mac
mailing list [http://article.gmane.org/gmane.comp.python.apple/14008].
He also suggested that I file a bug report, asking for an argument to be
added to python's configure script to avoid having to edit setup.py.
Thanks

The complex number is being formatted as if it were a string and simply
truncated to 5 characters. I would expect each part of the complex
number to be formatted according to the format specifier, i.e., in the
case of :.5 to both have 5 digits after the decimal point.

verify hostname against commonName in certificate
Message-ID: <1197387663.32.0.0598513497038.issue1589@psf.upfronthosting.co.za>
New submission from Andreas Hasenack:
(I hope I used the correct component for this report)
http://pypi.python.org/pypi/ssl/
I used the client example shown at
http://docs.python.org/dev/library/ssl.html#client-side-operation to
connect to a bank site called www.realsecureweb.com.br at
200.208.16.101. Its certificate signed by verisign. My OpenSSL has this
CA at /etc/pki/tls/rootcerts/verisign-inc-class-3-public-primary.pem.
The verification works.
If I make up a hostname called something else, like "wwws", and place it
in /etc/hosts pointing to that IP address, the SSL connection should not
be established because that name doesn't match the common name field in
the server certificate. But the SSL module happily connects to it
(excerpt below):
cert = verisign-inc-class-3-public-primary.pem
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ssl_sock = ssl.wrap_socket(s,
ca_certs="/etc/pki/tls/rootcerts/%s" % cert,
cert_reqs=ssl.CERT_REQUIRED)
ssl_sock.connect(('wwws', 443))
print repr(ssl_sock.getpeername())
output:
('200.208.16.101', 443)
('RC4-MD5', 'TLSv1/SSLv3', 128)
{'notAfter': 'Sep 10 23:59:59 2008 GMT',
'subject': ((('countryName', u'BR'),),
(('stateOrProvinceName', u'Sao Paulo'),),
(('localityName', u'Sao Paulo'),),
(('organizationName', u'Banco ABN AMRO Real SA'),),
(('organizationalUnitName', u'TI Internet PF e PJ'),),
(('commonName', u'www.realsecureweb.com.br'),))}
If I now open, say, a firefox window and point it to "https://wwws", it
gives me the expected warning that the hostname doesn't match the
certificate.
I'll attach the verisign CA certificate to make it easier to reproduce
the error.

Python 3.0a2, Gentoo Linux, x86
"make altinstall" installs idle, pydoc, and smtpd.py
This can partially break the previous Python install, which is counter
to the idea of altinstall being safe to use in parallel with an existing
install of a different version of Python.
IMO altinstall should install no files that lack a version number
somewhere in their path. I suggest having altinstall simply not install
pydoc, idle, and smtpd.py.

documentation misleading / confusing
Message-ID: <1197393124.23.0.965302988913.issue1591@psf.upfronthosting.co.za>
New submission from Mark Tomczak:
The help documentation for the popen2.Popen3 class includes the
following information:
class Popen3
| Class representing a child process. Normally instances are created
| by the factory functions popen2() and popen3().
This information is misleading because the function popen2.popen3
actually returns a tuple of file objects (child_stdout, child_stdin,
child_stderr), not an instance of class Popen3. Additionally, some of
the properties of class Popen3 are monkey-patched into the instance when
it is created and so do not appear in a dir(popen2.Popen3) call on the
class itself. This means that some automatic documentation generators
seem to fail to list these properties of the runtime Popen3 instance, as
they are not apparent in the class definition.
I suggest adding a note in the documentation of popen2.Popen3 to refer
users to the manual page http://docs.python.org/lib/popen3-objects.html.
An example of usage that takes into account the monkey-patched
properties would also be helpful.

Subject: [New-bugs-announce] [issue1595] Probable extra semicolon in
Py_LeaveRecursiveCall macro
Message-ID: <1197409249.11.0.710274454226.issue1595@psf.upfronthosting.co.za>
New submission from Amaury Forgeot d'Arc:
In file ceval.h, the macro Py_LeaveRecursiveCall is defined like this:
#define Py_LeaveRecursiveCall() \
do{ if((--PyThreadState_GET()->recursion_depth) < \
_Py_CheckRecursionLimit - 50); \
PyThreadState_GET()->overflowed = 0; \
} while(0)
The semicolon on the third line seems very suspicious to me: the if()
statement has no side effect, and "overflowed" is always reset to zero.
I don't really understand the consequences, though. The variable seems
to be used as an additional protection against C code that does not
correctly unwind when the recursion limit is hit.

better in 2.x
Message-ID: <1197410546.31.0.23440598734.issue1596@psf.upfronthosting.co.za>
New submission from Alexandre Vassalotti:
I think Python 2.x should mimic, or improve on, the behavior of Py3k for
handling broken pipes. That is:
1. Don't print the message "close failed: [Errno 32] Broken pipe",
from filemodule.c; since this is impossible to override from Python.
2. Check sys.stdout if it's closed before calling the print routine.
Raise an IOError if so.
Finally, here's some examples to illustrate what I am saying:
alex:~% python -c "print" | head -n0
close failed: [Errno 32] Broken pipe
alex:~% python -c "while 1: print" | head -n0
[The loop continues running, even if the output stream is closed]
^C
Traceback (most recent call last):
File "<string>", line 1, in <module>
KeyboardInterrupt
close failed: [Errno 32] Broken pipe
alex:~% py3k -c "print()" | head -n0
alex:~% py3k -c "while 1: print()" | head -n0
Traceback (most recent call last):
...
IOError: [Errno 32] Broken pipe

Message-ID: <1197427257.83.0.419655228027.issue1598@psf.upfronthosting.co.za>
New submission from Scott Moser:
I'm running into a problem with imaplib where it is unable to download a
message. The example code at
http://www.python.org/doc/current/lib/imap4-example.html easily
demonstrates the problem.
#!/usr/bin/python
import getpass, imaplib
M = imaplib.IMAP4("my.imap.host.tld")
M.login(getpass.getuser(), getpass.getpass())
M.debug = 5
M.select("msg-test")
typ, data = M.search(None, 'ALL')
for num in data[0].split():
typ, data = M.fetch(num, '(RFC822)')
print 'Message %s\n%s\n' % (num, data[0][1])
M.close()
M.logout()
The majority of the messages transfer correctly, but some do not. I've
put 3 messages in the 'msg-test' folder, and one of them causes the
error below.
Traceback (most recent call last):
File "test.py", line 9, in <module>
typ, data = M.fetch(num, '(RFC822)')
File "/usr/lib/python2.5/imaplib.py", line 437, in fetch
typ, dat = self._simple_command(name, message_set, message_parts)
File "/usr/lib/python2.5/imaplib.py", line 1055, in _simple_command
return self._command_complete(name, self._command(name, *args))
File "/usr/lib/python2.5/imaplib.py", line 887, in _command_complete
raise self.abort('command: %s => %s' % (name, val))
imaplib.abort: command: FETCH => unexpected response: ')'
imaplib.py has a comment in _get_tagged_response:
# Some have reported "unexpected response" exceptions.
# Note that ignoring them here causes loops.
# Instead, send me details of the unexpected response and
# I'll update the code in `_get_response()'.
I can not provide access to the imap host, but I can help debug wherever
possible.
The most recent log messages are in the file attachment.

Message-ID: <1197450243.14.0.729685827203.issue1600@psf.upfronthosting.co.za>
New submission from Mark Summerfield:
I don't know if this is a bug, but it is certainly a difference in
behavior between platforms:
Python 3.0a2 on linux2:
>>> "{0:.3e}".format(123.45678901)
'1.235e+02'
Python 3.0a2 on win32:
>>> "{0:.3e}".format(123.45678901)
'1.235e+002'
It seems to me that str.format() should produce consistent results
across platforms, but I don't think the PEP says anything either way.

Message-ID: <1197450599.05.0.953423788601.issue1601@psf.upfronthosting.co.za>
New submission from Mark Summerfield:
(1) IDLE starts up on Windows OK, but if I press Alt+F the file menu
comes up giant sized (i.e., each menu entry is almost as tall as the
screen).
(2) If I open a file using Ctrl+O, the Open dialog pops up fine, but
when I select a file and click Open, IDLE crashes.
Oh, and (no version of) IDLE respects the cursor blink setting on Windows.

(Py30a2)
Message-ID: <1197453390.87.0.813702844893.issue1602@psf.upfronthosting.co.za>
New submission from Mark Summerfield:
I am not sure if this is a Python bug or simply a limitation of cmd.exe.
I am using Windows XP Home.
I run cmd.exe with the /u option and I have set my console font to
"Lucida Console" (the only TrueType font offered), and I run chcp 65001
to set the utf8 code page.
When I run the following program:
for x in range(32, 2000):
print("{0:5X} {0:c}".format(x))
one blank line is output.
But if I do chcp 1252 the program prints up to 7F before hitting a
unicode encoding error.
This is different behaviour from Python 2.5.1 which (with a suitably
modified print line) after chcp 65001 prints up to 7F and then fails
with "IOError: [Errno 0] Error".

Passing an interable to the __init__ method of an existing deque
appends those elements, rather than reinitializing the deque with the

Subject: [New-bugs-announce] [issue1611] doctest.testmod gets noisy if
called more than once per SystemExit
Message-ID: <1197555194.14.0.664818118617.issue1611@psf.upfronthosting.co.za>
New submission from Pat LaVarre:
SUMMARY:
Calling doctest.testmod more than once before SystemExit spews stderr
messages such as "*** DocTestRunner.merge: '__main__' in both testers;
summing outcomes"
STEPS TO REPRODUCE:
$ cat tttestmod.py
import doctest
doctest.testmod() # 1
doctest.testmod() # 2
doctest.testmod() # 3
$
ACTUAL RESULTS:
$ python ./tttestmod.py
*** DocTestRunner.merge: '__main__' in both testers; summing outcomes.
*** DocTestRunner.merge: '__main__' in both testers; summing outcomes.
$
EXPECTED RESULTS:
$ python ./tttestmod.py
$
WORKAROUND:
Filter stdout.write calls from doctest.py to squelch the noise.
REGRESSION/ ISOLATION:
$ python --version
Python 2.5.1
$
Also mentioned 2006-10 in comp.lang.python at DocTestRunner.merge
verbose,
i.e., http://groups.google.com/group/comp.lang.python/search?
group=comp.lang.python&q=DocTestRunner.merge+verbose
Not yet found in Bugs.python.org at DocTestRunner.
NOTES:
We can reasonably expect newbies to doctest random things
that need to be doctested more than once.
We can't reasonably expect newbies to know to how to filter doctest
stdout,
for example as below.
#!/usr/bin/env python
r""" ttestmod.py
Filter Doctest stdout a la http://wiki.python.org/moin/doctest
to call doctest.testmod more than once per SystemExit
without producing noise.
>>> import random
>>> import sys
>>>
>>> die = random.randint(1, 6)
>>> print >>sys.stderr, die
>>>
>>> die == 6
True
>>>
"""
import sys
class DocTestOutput:
def __init__(self, out = sys.stdout):
self.out = out
self.write = self.writeOut
self.quietly = False
def writeOut(self, bytes):
head = "*** DocTestRunner.merge: '__main__"
tail = "' in both testers; summing outcomes."
if bytes.startswith(head):

if not self.quietly:

Subject: [New-bugs-announce] [issue1612] infinite recursion when using
collections.Sequence in a recursive function (Py30a2)
Message-ID: <1197560466.82.0.156189455789.issue1612@psf.upfronthosting.co.za>
New submission from Mark Summerfield:
In the attached file there are two tiny functions, flatten1() and
flatten2(). There is only one difference between them:
flatten1() has the line:
if isinstance(x, list):
and flatten2() has this line instead:
if isinstance(x, collections.Sequence):
flatten1() works perfectly in Python 2.5.1 and Python 30a2 (just comment
out the flatten2() code).
But flatten2() goes into "infinite" recursion in Python 30a2 when trying
to flatten list "c".

Subject: [New-bugs-announce] [issue1615] descriptor protocol bug
Message-ID: <1197576817.5.0.617961278098.issue1615@psf.upfronthosting.co.za>
New submission from ganges master:
it seems the code of PyObject_GenericGetAttr, which invokes the
descriptor protocol, silences any AttributeErrors raised by the
descriptor, for classes that also define __getattr__. it should
propagate up rather than being silently ignored.
the attached example is quite artificial, but it's a simplification of
real world code i had hard time debugging. turned out i misspelled an
attribute name inside the property getter function, which raised an
AttributeError as expected -- but the exception i got was quite
misleading, saying the instance has no attribute named so.
this bug only happens when the class defines a custom __getattr__. see
attached demo file for details.

New submission from Filip Salomonsson:
locale.strxfrm currently does not handle non-ascii strings:

Python 3.0a2 (py3k:59482, Dec 13 2007, 21:27:14)

The patch does not include what's needed to define HAVE_WCSXFRM, since I
really don't know how to do that properly (I edited 'configure' and
'pyconfig.h.in' manually to compile it).

New submission from Christian Heimes:
As reported by Duncan Booth at
http://permalink.gmane.org/gmane.comp.python.general/551183 the new
@spam.getter syntax modifies the property in place but it should create
a new one.
The patch is the first draft of a fix. I've to write unit tests to
verify the patch. It copies the property and as a bonus grabs the
__doc__ string from the getter if the doc string initially came from the
getter as well.

New submission from Gregory P. Smith:
The resolution to http://bugs.python.org/issue1608 looks like it'll add
a -fwrapv gcc flag when building python. This works around the issue
nicely on one compiler (gcc) but doesn't fix our fundamentally broken code.
We should fix all dependencies on integer overflow behavior, starting by
making everything compile properly with gcc's -Wstrict-overflow and
-Werror flags.

Message-ID: <1197595878.01.0.706002731675.issue1622@psf.upfronthosting.co.za>
New submission from Eric Huss:
Creating a ZipFile object with a certain type of zip file can cause it
to go into an infinite loop. The problem is the new extra field parsing
routine. It unpacks integers as a signed value, which if they are
sufficiently large (over 32767), then it will loop forever.
There are many places in the zipfile module that incorrectly unpack
values as signed integers, but this is the only place that I can
determine that causes a serious problem.
Attached is a fix.

Message-ID: <1197624030.23.0.503522059328.issue1625@psf.upfronthosting.co.za>
New submission from Thomas Herve:
The BZ2File class only supports one stream per file. It possible to have
multiple streams concatenated in one file, it the resulting data should
be the concatenation of all the streams. It's what the bunzip2 program
produces, for example. It's also supported by the gzip module.
Once this done, this would add the ability to open a file for appending,
by adding another stream to the file.
I'll probably try to do this, but the fact it's done in C (unlike gzip)
makes it harder, so if someone beats me to it, etc.

New submission from Sebastien BRACQUEMONT:
After a call to join() method on a Threading.thread object,there is no
way to successfully call start() method on it.
Indeed, the __started flag is not reset in the theading.Thread join()
method.
Since the start() method checks for __started flag , this flag is always
true after a first start, despite the thread was effectively stopped by
the join() call
Since it's perfectly legal to store a threading.Thread object in a
variable or an object member, i think the join() behaviour is odd
because it prevents instance reusability.

Content-Length: -1
Message-ID: <1197636721.61.0.0455165758222.issue1627@psf.upfronthosting.co.za>
New submission from ?lvaro Iradier:
When opening an IP Webcam URL with urllib2, the response is a continuous
secuence of Jpeg files from the server, preceded by the following headers:
Server: DM-Web
Content-type:
multipart/x-mixed-replace;boundary=0plm(Pico-Web:Server-Push:Boundary-String)1qaz
Content-length: -1
As you can see, the Content-Type is multipart/x-mixed-replace, and the
Content-Length reported by the server is '-1', which is strange (I guess
it would be better not to report Content-Length)
The problem is trying to read anything from the file-like object
returned by urlopen will block forever. Problem seems to be here, in
httplib.py, class HTTPResponse, method 'begin':
...
# will the connection close at the end of the response?
self.will_close = self._check_close()
# do we have a Content-Length?
# NOTE: RFC 2616, S4.4, #3 says we ignore this if tr_enc is
"chunked"
length = self.msg.getheader('content-length')
if length and not self.chunked:
try:
self.length = int(length)
except ValueError:
self.length = None
else:
self.length = None
...
The length attribute is being set to '-1' which leads to blocking when
reading from the endless stream of data. (See the read method in class
_fileobject, socket.py).
I don't know if this is the right fix, but I would suggest changing:
length = self.msg.getheader('content-length')
if length and not self.chunked:
to:
length = self.msg.getheader('content-length')
if length >= 0 and not self.chunked:

Message-ID: <1197680493.69.0.0120420737472.issue1631@psf.upfronthosting.co.za>
New submission from Nishkar Grover:
It would be nice if we could send output from subprocess.Popen objects
to any object with a write() method.
Consider the following example, where I'm using Python 2.4.4 (#1, Jun 28
2007, 15:10:17, GCC 3.4.3 on linux2)...
>>>
>>> fh = open('/tmp/file.txt', 'w')
>>> cmdObj = subprocess.Popen('uname -a', shell=True, stdout=fh)
>>> fh.close()
>>> fh = open('/tmp/file.txt', 'r')
>>> fh.read()
'Linux northstar 2.6.9-42.0.2.IT111843.1.ELsmp #1 SMP Fri May 11
18:50:54 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux\n'
>>>
That demonstrates that I can successfully send the stdout output from my
subprocess.Popen object to a file handle.
I tried to send that output to a custom object that has a write() method...
>>>
>>> class Foo(object):
... def write(self, msg):
... sys.stdout.write('*** %s ***' % msg.rstrip() + os.linesep)
... sys.stdout.flush()
... def close(self):
... pass
...
>>>
>>> foo = Foo()
>>>
>>> cmdObj = subprocess.Popen('uname -a', shell=True, stdout=foo)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/rel/lang/python/2.4.4-4/lib/python2.4/subprocess.py", line 534,
in __init__
(p2cread, p2cwrite,
File "/rel/lang/python/2.4.4-4/lib/python2.4/subprocess.py", line 840,
in _get_handles
c2pwrite = stdout.fileno()
AttributeError: 'Foo' object has no attribute 'fileno'
>>>
so I gave it a fileno() method that returns None...
>>>
>>> class Foo(object):
... def write(self, msg):
... sys.stdout.write('*** %s ***' % msg.rstrip() + os.linesep)
... sys.stdout.flush()
... def close(self):
... pass
... def fileno(self):
... return None
...
>>>
>>> foo = Foo()
>>>
>>> cmdObj = subprocess.Popen('uname -a', shell=True, stdout=foo)
>>> Linux northstar 2.6.9-42.0.2.IT111843.1.ELsmp #1 SMP Fri May 11
18:50:54 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux
>>>
Notice that the output went straight to the console and bypassed my
'foo' object's write() method.

New submission from Jack Atkinson:
I found this problem while using PySNMP and trying to load a custom MIB
converted to python code. Inside the PySNMP, it uses execfile() to load
the python MIBs, and I assume so it won't be put into a separate
namespace. On one particular MIB, which I cannot modify because it's a
company product MIB, this error of unable to take in more than 255
arguments occurs. The problem line is quite long, but surely in this
day and age of 32 bit to 64 bit machines this 255 constraint could be
done away with in the execfile function. I'm assuming the 255
constraint has something to do with unsigned 8 bit number.

Subject: [New-bugs-announce] [issue1638] %zd configure test fails on Linux
Message-ID: <1197836573.7.0.318332454178.issue1638@psf.upfronthosting.co.za>
New submission from Hrvoje Nik?i?:
The printf("%zd", ...) configure test fails on Linux, although it
supports the %zd format. config.log reveals that the test tests for %zd
with Py_ssize_t, which is (within the test) typedeffed to ssize_t. But
the appropriate system header is not included by the test, and ssize_t
is not defined. This results in Py_ssize_t not being correctly defined,
and the test failing.
According to http://tinyurl.com/3dhbbm/, ssize_t is defined in
<sys/types.h>. Adding #include <sys/types.h> manually to the test fixes
the test for me. A patch like the one attached should fix the problem.

New submission from Christian Heimes:
The patch adds several small enhancements to the math module and pyport.h.
* Py_MATH_PI and Py_MATH_E in long double precision
* Py_IS_NAN and Py_IS_INFINITY use isnan() and isinf() functions were
available (checked by configure)
* isnan and isinf for the math module
* Bessel (1st and 2nd kind), erf, erfc, lgamma function for math module.
They are defined in almost (or all?) math libraries.
Together with http://bugs.python.org/issue1635 it implements most of PEP
754.

Subject: [New-bugs-announce] [issue1641] asyncore delayed calls feature
Message-ID: <1197908693.3.0.330108725692.issue1641@psf.upfronthosting.co.za>
New submission from Giampaolo Rodola':
Hi,
I post this message here in the hope someone using asyncore could review
this.
Since the thing I miss mostly in asyncore is a system for calling a
function after a certain amount of time, I spent the last 3 days trying
to implement this with the hopes that this could be included in asyncore
in the the future.
The logic consists in calling a certain function (the "scheduler") at
every loop to check if it is the proper time to call one or more
scheduled functions.
Such functions are scheduled by the new delayed_call class which is very
similar to the DelayedCall class defined in /twisted/internet/base.py I
drew on.
It provides a basic API which can be used for setting, resetting and
canceling the scheduled functions.
For better performance I used an heap queue structure. This way the
scheduler() only needs to check the scheduled functions due to expire
soonest.
The following code sample implements an idle-timeout capability using
the attached modified asyncore library.
--- code snippet ---
import asyncore, asynchat, socket
class foo(asynchat.async_chat):
def __init__(self, conn=None):
asynchat.async_chat.__init__(self, conn)
self.set_terminator(None)
self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
self.connect(('127.0.0.1', 21))
self.scheduled_timeout = self.call_later(120, self.handle_timeout)
def collect_incoming_data(self, data):
self.scheduled_timeout.reset()
# do something with the data...
def handle_timeout(self):
self.push("500 Connection timed out.\r\n")
self.close_when_done()
def close(self):
if not self.scheduled_timeout.cancelled:
self.scheduled_timeout.cancel()
asyncore.dispatcher.close(self)
foo()
asyncore.loop()
--- /code snippet ---
Today I played a little more with it and I tried to add bandwidth
throttling capabilities to the base asynchat.py.
The code could be surely improved but it's just an example to show
another useful feature which wouldn't be possible to implement without
having a "call_later" function under the hood:
--- code snippet ---
class throttled_async_chat(asynchat.async_chat):
# maximum number of bytes to transmit in a second (0 == no limit)
read_limit = 100 * 1024
write_limit = 100 * 1024
# smaller the buffers, the less bursty and smoother the throughput
ac_in_buffer_size = 2048
ac_out_buffer_size = 2048
def __init__(self, conn=None):
asynchat.async_chat.__init__(self, conn)
self.read_this_second = 0
self.written_this_second = 0
self.r_timenext = 0
self.w_timenext = 0
self.r_sleep = False
self.w_sleep = False
self.delayed_r = None
self.delayed_w = None
def readable(self):
return asynchat.async_chat.readable(self) and not self.r_sleep
def writable(self):
return asynchat.async_chat.writable(self) and not self.w_sleep
def recv(self, buffer_size):
chunk = asyncore.dispatcher.recv(self, buffer_size)
if self.read_limit:
self.read_this_second += len(chunk)
self.throttle_read()
return chunk
def send(self, data):
num_sent = asyncore.dispatcher.send(self, data)
if self.write_limit:
self.written_this_second += num_sent
self.throttle_write()
return num_sent
def throttle_read(self):
if self.read_this_second >= self.read_limit:
self.read_this_second = 0
now = time.time()
sleepfor = self.r_timenext - now
if sleepfor > 0:
# we've passed bandwidth limits
self.r_sleep = True
def unthrottle():
self.r_sleep = False
self.delayed_r = self.call_later((sleepfor * 2), unthrottle)
self.r_timenext = now + 1
def throttle_write(self):
if self.written_this_second >= self.write_limit:
self.written_this_second = 0
now = time.time()
sleepfor = self.w_timenext - now
if sleepfor > 0:
# we've passed bandwidth limits
self.w_sleep = True
def unthrottle():
self.w_sleep = False
self.delayed_w = self.call_later((sleepfor * 2), unthrottle)
self.w_timenext = now + 1
def close(self):
if self.delayed_r and not self.delayed_r.cancelled:
self.delayed_r.cancel()
if self.delayed_w and not self.delayed_w.cancelled:
self.delayed_w.cancel()
asyncore.dispatcher.close(self)
--- /code snippet ---
I don't know if there's a better way to implement this "call_later" feature.
Maybe someone experienced with Twisted could provide a better approach.
I would ask someone using asyncore to review this since, IMHO, it would
fill a very big gap.

When trying to delete the .value member of ctypes simple types my python

$ python
Python 2.5.1 (r251:54863, Oct 5 2007, 13:36:32)

>>> from ctypes import c_long
>>> c = c_long(1)
>>> c.value
1
>>> del c.value
Segmentation fault (core dumped)
Admittedly there is no good usecase for this, but it should raise an
exception and not segfault.

Subject: [New-bugs-announce] [issue1643] Add group() to itertools
Message-ID: <1197942559.18.0.611472238589.issue1643@psf.upfronthosting.co.za>
New submission from Kirk McDonald:
One question which is asked with surprising frequency in #python is how
to yield multiple objects at a time from an iterable object. That is,
given [1, 2, 3, 4, 5, 6], get [(1, 2), (3, 4), (5, 6)].
The "grouper" function in the itertools recipes page provides one
pattern for this. A similar function (which behaves differently when the
length of the iterable is not evenly divisible by n) looks like this:
def group(iterable, n=2):
return itertools.izip(*(iter(iterable),)*n)
This code is fairly opaque to the novice. It is ugly, and takes a bit of
head-scratching to realize exactly what it is doing. Because this
operation is asked for with some frequency, and because this general
implementation is so ugly, I believe it belongs in the library.
There is a related function which is asked for much less frequently, but
which is a more general case of the group() function listed above. This
other function has a third "step" argument. This argument controls how
far each group is in advance of the previous group. For example:
list(group([1, 2, 3, 4], n=2, step=1)) -> [(1, 2), (2, 3), (3, 4)]
The original function is equivalent to this function when step is equal
to n.
Please find attached a patch with implementation, documentation, and tests.

I think that the cached default encoding version of the unicode object
should be limited in size. It's probably a bad idea to cache a 100MB of
data. For large amount strings and unicode objects the user should do
explicit caching if required.

Subject: [New-bugs-announce] [issue1652] subprocess should have an option to
restore SIGPIPE to default action
Message-ID: <1197992466.47.0.0612439954222.issue1652@psf.upfronthosting.co.za>
New submission from Colin Watson:
On Unix, Python sets SIGPIPE to SIG_IGN on startup, because it prefers
to check every write and raise an IOError exception rather than taking
SIGPIPE. This is all well and good for Python itself. However,
non-Python Unix subprocesses generally expect to have SIGPIPE set to the
default action, since that's what will happen if they're started from a
normal shell. If this is not the case, then rather than taking SIGPIPE
when a write fails due to the reading end of a pipe having been closed,
write will return EPIPE and it's up to the process to check that. Many
programs are lazy and fail to check for write errors, but in the
specific case of pipe closure they are fine when invoked from a normal
shell because they rely on taking the signal. Even correctly written
programs that diligently check for write errors will typically produce
different (and confusing) output when SIGPIPE is ignored. For instance,
an example only very slightly adapted from one in the subprocess
documentation:
$ dd if=/dev/zero of=bigfile bs=1024 seek=10000 count=1
1+0 records in
1+0 records out
1024 bytes (1.0 kB) copied, 0.000176709 seconds, 5.8 MB/s
$ cat bigfile | head -n0
$ cat t.py
from subprocess import Popen, PIPE
p1 = Popen(["cat", "bigfile"], stdout=PIPE)
p2 = Popen(["head", "-n0"], stdin=p1.stdout, stdout=PIPE)
output = p2.communicate()[0]
$ python t.py
cat: write error: Broken pipe
In some cases this problem can be much more significant. For instance,
it is very common for shell scripts to rely on SIGPIPE's default action
in order to behave correctly. A year or two ago I ran into this in OS
installer code I was writing in Python, which called some underlying
utility code in shell and C to deal with disk partitioning. In the event
that the Python code failed to handle an exception, the shell script
being run in a subprocess would spiral out of control rather than
cleanly exiting at the first sign of trouble. This actually caused
massive data loss on several testers' systems and required a quick
release to fix
(https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/40464 and
https://wiki.ubuntu.com/DapperBeta/PartitionTableCorruption). Now
obviously this was ultimately my fault for failing to catch the
exceptional condition in testing, but this misdesign in Python and the
lack of any documentation of this gotcha really didn't help at the time.
For the record, the fix was to call this in a preexec_fn:
signal.signal(signal.SIGPIPE, signal.SIG_DFL)
This is an area of Unix that's very easy to get wrong. I've written my
own subprocess handling library in C for another project, and I still
found it non-trivial to track this down when it bit me. Since it
essentially arises due to an implementation detail of the Python
language, I think it should also be Python's responsibility to fix it up
when subprocesses are involved.
There are many ways to invoke subprocesses in Python, but the new,
all-singing, all-dancing one is of course the subprocess module. I think
it would be sufficient for that to do the right thing, or at least have
an option to do so, and it's certainly the easiest place to add the
option. I'm attaching a suggested patch which adds a restore_sigpipe
option and documents it in what seem to be all the relevant places.
Note that nearly all the examples end up with restore_sigpipe enabled.
In some future release of Python, I think this should be the default.
I'm not entirely familiar with migration plan processes in Python; how
should this be done?

Message-ID: <1197999998.22.0.922085373773.issue1653@psf.upfronthosting.co.za>
New submission from Joseph Armbruster:
I added an option to msi.py (and a support script) that allows the user
to optionally decompile the python30.chm post installation. In doing
so, I was testing out help() from the interpreter and stumbled upon a
few things that I think are issues. One of the ways I experimented, was
by typing the following commands at the interpreter, to see what I could
pull up on the global statement:
help()
keywords
global
I had run into the following issues on my way. Additional eyes /
insight would definitely be helpful. Just a couple forewords:
- os.environ.get("PYTHONDOCS") returns 'C:\\Python30\\Doc'
- my version of the installer decompiled the Python30.chm as dictated by
pydoc. So that, c:\Python30\Doc has folders c-api, data, distutils, etc..
If I missed anything basic with these, my apologies in advanced.
Issue 1: PYTHONDOCS does not appear to be respected.
* I generated python-3.0.13865.msi and installed
* post-install I set PYTHONDOCS to C:\python30\doc
* I fired up a new command prompt
* Fire up Python3k interpreter and attempt the help() session listed
above.
* I had to hack at pydoc.py, since the #windows statement never gets
reached.
join = os.path.join
if sys.platform=='win32': #hack
self.docdir=join(execdir,'doc') #...
else: #...
for dir in [os.environ.get('PYTHONDOCS'),
homedir and os.path.join(homedir, 'doc'),
join(execdir, 'doc'), # for Windows
Issue 2: pydoc.py class Helper member keywords contain several invalid
paths. For instance:
'global': ('ref/global', 'NAMESPACES'),
Most of the keywords appear to have the ref/ prefixes.
Issue 3: formatter.py will throw an exception within push_margin /
pop_margin on the lines where a len(fstack) is attempted. The two lines
look like this:
self.writer.new_margin(margin, len(fstack))
I do not have a patch for this, since i'm still wandering about through
the whole installer generation stuffs. When I get home, I will examine
further.
Thoughts?

My interface is almost identical to Twisted's API except for some names.

New submission from Quentin Gallet-Gilles:
While investigating for the stdlib reorg of Tkinter, I came across the
following error:
~/dev/py3k$ ./python Lib/lib-tk/Dialog.py
Traceback (most recent call last):
File "Lib/lib-tk/Dialog.py", line 45, in <module>

File "/home/quentin/dev/py3k/Lib/lib-tk/Tkinter.py", line 1921, in

for k in cnf.keys():
RuntimeError: dictionary changed size during iteration
The attached patch adds list() around the dict.keys() call.
On a related note, this doesn't appear to be an isolated error, since a
similar issue (#1649) was recently fixed in r59554. Would it be a good
idea to look for other identical cases ?

Message-ID: <1198078803.93.0.586517631888.issue1661@psf.upfronthosting.co.za>
New submission from Brandon Corfman:
Python's documentation for the re.match function is match(pattern,
string, [flags]) where pattern can be either a regex string or a
compiled regex object. If it's a compiled regex object, then supplying
an optional flag to re.match (in my case, re.IGNORECASE) doesn't work
and, more to the point, fails silently. I think this should throw an
exception if it's not going to work.
See

Subject: [New-bugs-announce] [issue1666] integer subclass range behavior
Message-ID: <1198121982.55.0.188898496542.issue1666@psf.upfronthosting.co.za>
New submission from Joseph Armbruster:
I was wondering what would happen, so I tried this out for the heck of
it with:
Python 3.0a2 (py3k:59572M, Dec 19 2007, 15:54:07) [MSC v.1500 32 bit
(Intel)]
on win32
class a(int):
def __new__(cls,number):
return int.__new__(cls,number)
for x in range(0,a(5)):
print(x)
This resulted in a:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "a.py", line 5, in <module>
for x in range(0,a(5)):
SystemError: ..\Objects\longobject.c:400: bad argument to internal
function
[41030 refs]
It looks like the rangeobject performs a FitsInLong test on each of
the parameters to range, which uses the function
_PyLong_FitsInLong(PyObject *vv) within longobject.c. In tern, this
performs a typecheck: #define PyLong_CheckExact(op) (Py_TYPE(op) ==
&PyLong_Type) that fails.

New submission from Joseph Armbruster:

The intent of the -E command line parameter is not entirely clear from
it's description. If it implies that All environment variables will be
ignored then this is not currently the case. If it implies that a few
select environment variables will be ignored, then this is partially the
case.
See the attached patch for the potentially odd cases.

Message-ID: <1198140802.03.0.559721880432.issue1669@psf.upfronthosting.co.za>
New submission from Tim Koopman:
When using rmtree with a symlink to a directory as path, it will first
follow the symlink, (try to) remove all the contents of the source
directory and then raise the exception "OSError: [Errno 20] Not a
directory".
Expected behaviour: The function should only raise an exception.
If the current behaviour is indeed wanted, it should a least be documented.

Message-ID: <1198166659.78.0.580498645891.issue1674@psf.upfronthosting.co.za>
New submission from Eric Moyer:
I installed the python-2.5.1.msi stable package from the python.org
website using a super-user account on my system. I installed "for all
users" and used the default location and chose to install everything,
not omitting any component.
After installation, I moved the startup menu folder to be a sub-menu of
my Programming startup menu folder. Then I ran IDLE and typed in a few
recipes from the itertools package to ensure that everything worked.
Then I logged out and logged back in with my normal user account. In my
normal account, the three startup menu items "IDLE (Python GUI)",
"Module Docs", and "Python (command line)" all crash. The first two
crash with a window titled "pythonw.exe - Application Error". The last
one opens an empty command prompt window before dying with a window
titled "python.exe - Application Error". All the error windows have the
text, "The application failed to initialize properly (0xc0000022). Click
on OK to terminate the application"
Since it works when I am logged in as an administrator, my guess is that
the error has something to do with windows security.

Message-ID: <1198180171.38.0.482360233935.issue1675@psf.upfronthosting.co.za>
New submission from Isaac Morland:
There appears to be a race condition in os.makedirs. Suppose two
processes simultaneously try to create two different directories with a
common non-existent ancestor. For example process 1 tries to create
"a/b" and process 2 tries to create "a/c". They both check that "a"
does not exist, then both invoke makedirs on "a". One of these will
throw OSError (due to the underlying EEXIST system error), and this
exception will be propagated. Note that this happens even though the
two processes are trying to create two different directories and so one
would not expect either to report a problem with the directory already
existing.

I've just updated to Tk 8.5 on OS X (Leopard, 10.5.1) and have rebuilt
Python to link to the new version of Tk. I'm seeing tons of weird error

12/20/07 8:18:46 PM [0x0-0xa50a5].org.python.IDLE[1300] The process has
forked and you cannot use this CoreFoundation functionality safely. You

I'm not sure if this is a showstopper bug or not, but I'm a bit
concerned about all these error messages. Can someone investigate?

When running Python 2.5.1 stable in Windows, you can press Ctrl-C as
many times as you want and it will always output Keyboard Interrupt in

Python 3.0a+ will quit if you press ctrl-c too many times. The last
release of 3.0a2 can handle many interrupts before quitting, but the
latest snapshot (Dec 20th) can not.
Steps to reproduce:
Run python.exe
hold down ctrl-c, or press it many times. It will quit the interpreter
eventually.

Message-ID: <1198263226.4.0.968502752614.issue1683@psf.upfronthosting.co.za>
New submission from roudkerk:
I got a report that one of the tests for processing
(http://cheeseshop.python.org/pypi/processing) was failing with
Fatal Python error: Invalid thread state for this thread
when run with a debug interpreter. This appears to be caused by the
interaction between os.fork() and threads. The following attached
program reliably reproduces the problem for me on Ubuntu edgy for x86.
All that happens is that the parent process starts a subthread then
forks, and then the child process starts a subthread.
With the normal interpreter I get
started thread -1211028576 in process 18683
I am thread -1211028576 in process 18683
started thread -1211028576 in process 18685
I am thread -1211028576 in process 18685
as expected, but with the debug interpreter I get
started thread -1210782816 in process 18687
I am thread -1210782816 in process 18687
started thread -1210782816 in process 18689
Fatal Python error: Invalid thread state for this thread
[5817 refs]
Notice that the child process is reusing a thread id that was
being used by the parent process at the time of the fork.
The code raising the error seems to be in pystate.c:
PyThreadState *
PyThreadState_Swap(PyThreadState *new)
{
PyThreadState *old = _PyThreadState_Current;
_PyThreadState_Current = new;
/* It should not be possible for more than one thread state
to be used for a thread. Check this the best we can in
debug
builds.
*/
#if defined(Py_DEBUG) && defined(WITH_THREAD)
if (new) {
PyThreadState *check = PyGILState_GetThisThreadState();
if (check && check != new)
Py_FatalError("Invalid thread state for this
thread");
}
#endif
return old;
}
It looks as though PyGILState_GetThisThreadState() is returning the
thread state of the thread from the parent process which has the same
id as the current thread. Therefore the check fails.
I think the thread local storage implementation in thread.c should
provide a function _PyThread_ReInitTLS() which PyOS_AfterFork() can
call. I think _PyThread_ReInitTLS() just needs to remove and free
each "struct key" in the linked list which does not match the id of
the calling thread.

Message-ID: <1198274242.65.0.204698066624.issue1684@psf.upfronthosting.co.za>
New submission from Fazal Majid:
The CGI specification does not specify the working directory the CGI is
invoked in, but the usual behavior is to use the directory containing
the script.
CGIHTTPServer should either change working directory by default (see
patch below), or offer a hook to be called before the exec() call to the
CGI.

Message-ID: <1198300635.1.0.891509425639.issue1685@psf.upfronthosting.co.za>
New submission from PyScripter:
linecache.updatecache works as follows after it finds a module name:
fp = open(fullname, 'rU')
lines = fp.readlines()
fp.close()
It then tries to detect a file encoding comment...
The problem is that readlines fails with a UnicodeDecodeError if the
file is utf8 encoded, the preferred locale encoding is something else
and the file contains characters that cannot be decoded.
Instead the function should:
a) read the raw data into a bytes object
b)then search for a file encoding comment and
c)use one if found else use utf8 since this is not the default file
encoding.

Message-ID: <1198357772.97.0.682407228029.issue1688@psf.upfronthosting.co.za>
New submission from Vlastimil Brom:
While testing the 3.0a2 build (on Win XPh SP2, Czech), I found a
possible bug in the input() function;
if the prompt text contains non-ascii characters (even those present in
the default charset of the system locale - Czech in this case) the
prompt is displayed incorrectly; however, the inserted value is treated
as expected.
The print() function deals with these characters correctly.
This bug occurs in the system console (cmd.exe) only, using idle
everything works ok.

Hi, I am having problems both in the Windows version on the Linux

>>> 2.0
2.0
>>> 1.55
1.55
>>> 1.56
1.5600000000000001

>>> 1.64
1.6399999999999999
>>> 1.71
1.71
>>> 6.0
6.0
Recalling that the error happens only with the digit 6 in float.

New submission from Olivier Croquette:
Some servers allow the @ character is usernames. It gives URLs like:
ftp://user at xyz@host/dir
user at xyz could for example by an email address.
I am not sure if this is RFC compliant. What's sure is that is makes
trouble with urlparse:
>>> from urlparse import urlparse
>>> p = urlparse("ftp://user at host1@host2/dir")
>>> print p.username
user
>>> print p.hostname
host1 at host2
By using rsplit instead of split in lib/python2.5/urlparse.py, the
problem can be solved.

Message-ID: <1198729720.38.0.104417938854.issue1702@psf.upfronthosting.co.za>
New submission from Devin Jeanpierre:
I was slightly misled by the wording of part of the docs
(http://docs.python.org/lib/bltin-file-objects.html):
"file() is new in Python 2.2. The older built-in open() is an alias
for file()."
I actually thought it meant that open was an alias of file, so
that 'open is file'. However,
>>> open is file
False
I feel that "alias" is the wrong word to use here, though I don't know
a suitable replacement.

Message-ID: <1198800874.65.0.655232075234.issue1703@psf.upfronthosting.co.za>
New submission from Philip Jenvey:
getpass (in particular _raw_input, used by unix_getpass and
default_getpass) prints out a password prompt to a stream (by default
stdout) but doesn't flush that stream. It assumes calling
sys.stdin.readline() to read the password causes stdout to be flushed
(probably a libc file buffering behavior)
This is a problem in Py3k where file buffering is done by Python;
getpass needs to manually flush the stream it prints the prompt to.
Otherwise the prompt isn't printed until after the password is entered
e.g.:
Python 3.0a2 (py3k:59601, Dec 27 2007, 14:28:14)
[GCC 4.1.3 20071209 (prerelease) (Debian 4.1.2-18)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import getpass
>>> getpass.getpass()
<no prompt is printed, i type 'foo\n', and only afterwards is the prompt
printed>
Password:
'foo'
>>>
Windows doesn't use _raw_input so it wouldn't see this issue.
Attached is a patch to flush the stream. There's no getpass tests so I
didn't get around to creating one for this issue. Ideally we'd test
getpass via spawning a python subprocess and ensuring its I/O looked
correct.
This was noticed on Jython as its file object is now based off Py3k's

Message-ID: <1198814325.03.0.53847270276.issue1704@psf.upfronthosting.co.za>
New submission from Rich Marinaccio:
I have been using python for Civilization IV map scripting, and I
believe I have found a small problem with the randint function. Once in
a blue moon, randint(a,b) returns b + 1, rather than a >= N <= b. I
have seen this behavior a few times. Here is the code I used to
determine this.
randIndex = PWRand.randint(0,len(preshuffle)-1)#PWRand calls randint
directly with these parameters
if randIndex < 0 or randIndex >= len(preshuffle):
raise ValueError, " bad index shuffling plot list randIndex=%(r)d
listLength=%(l)d, mapSize=%(s)d" % {"r":randIndex,"l":len
(preshuffle),"s":hm.mapWidth*hm.mapHeight}
#output is
ValueError: bad index shuffling plot list randIndex=1453
listLength=1453, mapSize=13824
according to the docs, the max randIndex should be listLength - 1

New submission from Wummel:
Hi,
the trace module does not properly count the global statement. So
coverage tests of functions that use the global statement always file.
To reproduce write a simple function using the global statement and
store it in "mytest.py" (which is attached). Then run "python -m trace
-c mytest.py".
You'll see that the global statement line will not be covered (ie. there
is no "1:" at the beginning of the line).
I tested with Python 2.5 and 2.4.

New submission from Andre Roberge:
There appears to be a bug in code.py in Python 3.0a2/a1.
I believe that the body of
InteractiveConsole().raw_input()
should be changed from
sys.stdout.write(prompt)
sys.stdout.flush()
return sys.stdin.readline()
to
return input(prompt)
Here's a sample session.

The same problem affects function definitions - it is impossible to

Message-ID: <1199024318.28.0.602984080184.issue1708@psf.upfronthosting.co.za>
New submission from umaxx:
here comes a simple patch for linecache core module, which does the
following:
- remove double comment
- instead of adding all lines with readlines() to the cache, just add
seek points for every line
- return lines from cached seek-points instead directly from dict-cache
advantages of this patch:
- reading lines from very big files (>1GB) is no problem anymore
- linecache can handle a large number of large files now
- updatecache() is faster now because "for line in fp:" is faster than
readlines()
disadvantages:
- reading a single line from cache will be a little bit slower, then
before because of extra open() call to the file
summary:
- this diff presents a different caching approach which is able to
handle a lot of large files too
__future__-work:
- the code is ugly and unstructured, someone needs to beautify it
- an extra function: get_list_of_lines_from_list_of_linenumbers() would
be nice to have
- test-cases for cache-consistence would be nice to have

The meaning of the "score" column shown when a search is done on the

Example:

To understand its meaning I had to find this document:
http://pycheesecake.org/#algorithm-for-computing-the-cheesecake-index
IMHO, it would be better putting a note somewhere in the pypi...
something which explains what the "score" value stands for.

Maybe it was once used for indexing, but is pointless now.

I have some configuration params with leading space. And program

(and trailing) spaces from values. This is very often the most wanted

it there.
Therefore I suggest to optionaly write string value as
