[issue6028] Interpreter crashes when chaining an infinite number of exceptions

2009-05-15 Thread Yury

New submission from Yury yury.sobo...@gmail.com:

def error_handle():
try:
print(5/0)
except:
error_handle()

error_handle()

Fatal Python error: Cannot recover from stack overflow.
Aborted

The interpreter should not crash. Perhaps a RuntimeError should be
thrown instead.

[issue6029] FAIL: test_longdouble (ctypes.test.test_callbacks.Callbacks) [SPARC/64-bit]

2009-05-15 Thread Peter Bray

New submission from Peter Bray pdb...@yahoo.com.au:

Greetings,

  I have downloaded and compiled Python 3.1b1 on Solaris 10 Update 6

test harness failure, which was on SPARC 64-bit.

  Included below are the initial details, is there something more I can
do to assist, if so, please be specific.

[issue1152248] Enhance file.readlines by making line separator selectable

2009-05-15 Thread Nick Coghlan

Nick Coghlan ncogh...@gmail.com added the comment:

While RDM's quick test is encouraging, I think one of the key things is
going to be developing tests for the various cases:

- binary mode, single byte line ending
- binary mode, multi-byte line ending
- text mode, single byte single char line ending*
- text mode, multi-byte single char line ending
- text mode, multiple char line ending

The text mode tests would need to cover a variety of encodings (e.g.
ASCII, latin-1, UTF-8, UTF-16, UTF-32 and maybe something like koi8-r
and/or some of the CJK codecs).

*if applicable to codec under test

[issue1152248] Enhance file.readlines by making line separator selectable

2009-05-15 Thread Antoine Pitrou

Antoine Pitrou pit...@free.fr added the comment:

-1 on this idea. readlines() exists precisely because line endings are
special when it comes to text IO (because of the various platform
differences).

If you want to split on any character, you can just use read() followed
by split(). No need to graft additional complexity on the file IO classes.

[issue6028] Interpreter crashes when chaining an infinite number of exceptions

2009-05-15 Thread Antoine Pitrou

Antoine Pitrou pit...@free.fr added the comment:

This is normal behaviour, actually. The RuntimeError *is* raised, but
you catch it in the except clause and then recurse again ad infinitum.
The interpreter realizes that it cannot recover from stack overflow,
as the message says, and then bails out.

[issue1152248] Enhance file.readlines by making line separator selectable

2009-05-15 Thread Antoine Pitrou

Antoine Pitrou pit...@free.fr added the comment:

Ok, let me qualify my position a bit:
- -1 for abusing the newline parameter
- -1 for abusing readlines()
- +0 on an additional method (readchunks was suggested) which does the
splitting, either on a single character or on a string

Please bear in mind the latter should involve, for each of the C and
Python implementations:
- a generic unoptimized version for BufferedIOBase
- a generic unoptimized version for TextIOBase
- an optimized version for BufferedReader/BufferedRandom
- an optimized version for TextIOWrapper

However, it is certainly an interesting task for someone wanting to play
with C code, optimizations, etc.

[issue1152248] Enhance file.readlines by making line separator selectable

2009-05-15 Thread Nick Coghlan

Nick Coghlan ncogh...@gmail.com added the comment:

I agree with Antoine - given that the newlines parameter now deals with
Skip's alternate line separator use case, a new method readrecords
that takes a mandatory record separator makes more sense than using
readlines to read things that are not lines. (of course, taking the
alternate line ending use case away also reduces the total number of use
cases for the new method).

Note that the problem with the read()+split() approach is that you
either have to read the whole file into memory (which this RFE is trying
to avoid) or you have to do your own buffering and so forth to split
records as you go. Since the latter is both difficult to get right and
very similar to what the IO module already has to do for readlines(), it
makes sense to include the extra complexity there.

I wonder how often this use case happens though. Usually you first split
on lines, and only then you split on another character or string (think
CSV files, HTTP headers, etc.).

When you don't split on lines, conversely, you probably have a binary
format, and binary formats have more efficient ways of chunking (for
example, a couple of bytes at the beginning indicating the length of the
chunk).

[issue5964] WeakSet cmp methods

2009-05-15 Thread Robert Schuppenies

Robert Schuppenies robert.schuppen...@gmail.com added the comment:

Maybe because I take the doc too specfic. It says A rich comparison
method may return the singleton NotImplemented if it does not implement
the operation for a given pair of arguments.

I see the type check of the 'other' object as an operation towards the
equal comparison, since it validates wether 'self' and 'other' can be
equal at all. If they are of a different type, then they cannot be
equal, thus the anwser to Are 'self' and 'other' equal? should be
False. This again, would mean an equal operation is implemented and
returning NotImplemented is not the right anwser.

But going through similar code snippets shows otherwise, so my
understanding must be lacking something. Therefore here is patch which
returns NotImplemented.

The explanation for NotImplemented is that an user-defined class may
decide it can compare equal to a WeakSet (without inheriting from
WeakSet). Returning NotImplemented from WeakSet.__eq__ gives a chance to
the user-defined class' __eq__ method to be called.

[issue1152248] Enhance file.readlines by making line separator selectable

2009-05-15 Thread Douglas Alan

Douglas Alan d...@alum.mit.edu added the comment:

Antoine Pitrou rep...@bugs.python.org wrote:

 Nick Coghlan ncogh...@gmail.com added the comment:

  Note that the problem with the read()+split() approach is that you
  either have to read the whole file into memory (which this RFE is 
trying
  to avoid) or you have to do your own buffering and so forth to split
  records as you go. Since the latter is both difficult to get right 
and
  very similar to what the IO module already has to do for 
readlines(), it
  makes sense to include the extra complexity there.

 I wonder how often this use case happens though.

Every day for me.  The reason that I originally brought up this request
some years back on comp.lang.python was that I wanted to be able to use
Python easily like I use the xargs program.

E.g.,

   find -type f -regex 'myFancyRegex' -print0 | stuff-to-do-on-each-
file.py

With -print0 the line separator is chaged to null, so that you can
deal with filenames that have newlines in them.

(find and xargs traditionally have used newline to separate files,
but that fails in the face of filenames that have newlines in them, so
the -print0 argument to find and the -0 argument to xargs were
thankfully eventually added as a fix for this issue.  Nulls are not
allowed in filenames.  At least not on Unix.)

 When you don't split on lines, conversely, you probably have a binary
 format,

That's not true for the daily use case I just mentioned.

|ouglas

P.S. I wrote my own version of readlines, of course, as the archives of
comp.lang.python will show.  I just don't feel that everyone should be
required to do the same, when this is the sort of thing that sysadmins
and other Unix-savy folks are wont to do on a daily basis.

P.P.S. Another use case is that I often end up with files that have
beeen transferred back and forth between Unix and Windows and
god-knows-what-else, and the newlines end up being some weird mixture of
carriage returns and line feeds (and sometimes some other stray
characters such as =20 or somesuch) that many programs seem to have a
hard time recognizing as newlines.

[issue6028] Interpreter crashes when chaining an infinite number of exceptions

2009-05-15 Thread Amaury Forgeot d'Arc

Amaury Forgeot d'Arc amaur...@gmail.com added the comment:

Hmm, the interpreter should not crash so easily with pyre Python code.
(The same code correctly raises RuntimeException wich python 2.x)
The issue should be corrected IMO.

The exact behavior seem to depend on where the recursion limit is detected:

- If it is detected at the beginning of the function (at the start of
PyEval_EvalFrameEx) or before the try statement, the exception is
correctly propagated and displayed. This case always happens with 2.x,
and you get the same on 3.0 if you add for example str()
at the beginning of the function.

- The crash occurs when the recursion limit is detected while
PyEval_EvalFrameEx calls PyErr_NormalizeException() (in the why ==
WHY_EXCEPTION block). This does not change the control flow: the
original exception is simply replaced by the RuntimeError, and nested
calls continue 50 more frames.

Here is a tentative patch.

[issue5353] Improve IndexError messages with actual values

2009-05-15 Thread Terry J. Reedy

Terry J. Reedy tjre...@udel.edu added the comment:

This issue is about formatting a value into an error message.
#1182143 is about adding values that have already been formatted into an
error message to the resulting exception object.  If this suggestion
were implemented, then IndexError would be added to the exceptions
covered by #1182143

Patches to mailing lists tend to get lost.  Thank you for finding
Bjourne's. I have invited him (at the email then given) to update it and
attach it here.

[issue5353] Improve IndexError messages with actual values

2009-05-15 Thread Raymond Hettinger

Raymond Hettinger rhettin...@users.sourceforge.net added the comment:

I've seen his patch and am working on my own variant that also attaches
the index value as a separate field in the args tuple.  The problem may
be that it slows down the code -- at first I thought that didn't matter,
but someone made a good effort to make the existing code fast (possibly
to support cases where IndexError is used for control flow instead of
for error conditions).

[issue5141] C API for appending to arrays

2009-05-15 Thread kxroberto

kxroberto kxrobe...@users.sourceforge.net added the comment:

I had a similar problem creating a C-fast array.array interface for Cython.
The array.pxd package here (latest zip file)
http://trac.cython.org/cython_trac/ticket/314
includes a arrayarray.h file, which provides ways for efficient creation
and growth from C (extend, extend_buffer, resize, resize_smart ). Its
probably in one of the next Cython distributions anyway, and will be
maintained. And perhaps array2 and arrayM extension subclasses (very
light-weight numpy) with public API coming soon too.
It respects the different Python versions, so its a lite quasi API.
And in case there will be a (unlikely) change in future Pythons, the
Cython people will take care as far as there is no official API coming up.
Or perhaps most people with such interest use Cython anyway.

[issue6015] Tkinter Scrollbar in OS X 10.5

2009-05-15 Thread Marc Culler

Marc Culler cul...@math.uic.edu added the comment:

I have the same issues with Python 2.6 code I have written.  In OS X
10.4 the scrollbars work correctly with a Tkinter Text widget.  The same
code running in 10.5 exhibits this erratic behavior.  It appears as
though mouse movement events are queued up, causing the mouse to get
ahead of the scrollbar.  Later, at some random time, it appears as
though the queued events get processed all at once, causing the
scrollbar to leap ahead of the mouse.  The scrollbar widget display also
becomes corrupted at times, with the blue color from the slider being
written into the buttons at the bottom.

[issue6028] Interpreter crashes when chaining an infinite number of exceptions

2009-05-15 Thread Antoine Pitrou

Antoine Pitrou pit...@free.fr added the comment:

Amaury, your patch might make some individual cases better, but it won't
prevent a FatalError from occurring in all cases.

Also, it makes things worse in the following case:

def recurse():
try:
recurse()
except:
recurse()

recurse()

(the script goes into an uninterruptible infinite loop, rather than
raising an explicit Fatal error)

More useful, IMHO, would be to patch Py_FatalError() so that a traceback
is printed.

2009-05-15 Thread Terry J. Reedy

Terry J. Reedy tjre...@udel.edu added the comment:

Having to bind and unbind a classmethod to get at the function is
definitely a bit weird, and also susceptible to changing implementation,
but do you have a practical use case to motivate the effort needed?

In Py3, '__func__' replaced 'im_func', and that is the name to use if
the attribute is added.  A change in 3.2 is at least as likely as a
change in 2.7.

[issue6031] BaseServer.shutdown documentation is incomplete

2009-05-15 Thread Gabriel Genellina

New submission from Gabriel Genellina gagsl-...@yahoo.com.ar:

BaseServer.shutdown is documented as Tells the serve_forever() loop to 
stop and waits until it does.

The docstring is much more explicit: Stops the serve_forever loop. 
Blocks until the loop has finished. This must be called while 
serve_forever() is running in another thread, or it will deadlock.

Combined with #2302 I'd rewrite both (rst and docstring) as:

BaseServer.shutdown(): Tells the serve_forever() loop to stop, and 
waits until the loop has finished. This must be called after 
serve_forever() has started and while it is running in another thread, 
or the shutdown() call will deadlock.

[issue4174] Performance optimization for min() and max() over lists

2009-05-15 Thread Daniel Diniz

Daniel Diniz aja...@gmail.com added the comment:

Given the drawbacks mentioned (and the fact that the current patch would
break when the list mutates under its feet), is this still valid?

[issue6033] LOOKUP_METHOD and CALL_METHOD optimization

2009-05-15 Thread Benjamin Peterson

New submission from Benjamin Peterson benja...@python.org:

This is an optimization ported from PyPy. [1] It tries to prevent bound
methods from being created by using the stack as a cache. I couldn't
apply this to builtin methods because those use a method-wrapper
descriptor. The results were not very impressive. However, I'm attaching
the patch to see if anyone else wants to look at it.

But here is the root cause.  The Python-3.1b1 files were created by Stuffit 
Expander ffrom the original 
Python-3.1b1 tar ball downloaded from the Python website.  Changing the Stuffit 
preferences does not 
make any difference.  

However, if that same tar ball is uncompressed by the  tar -zxf ... command, 
there are no directories.  
Only five simple files, as expected:

-rw-r--r--   1 jean  jean   61440 Jul 15  2008 wininst-6.0.exe
-rw-r--r--   1 jean  jean   65536 Jul 15  2008 wininst-7.1.exe

-rw-r--r--   1 jean  jean  196096 Jan 29 05:08 wininst-9.0.exe


After removing the directory files (and renaming the *.1.exe to *.exe), the 
regression tests passes.

[issue6034] Fix object.__reversed__ doc

2009-05-15 Thread Terry J. Reedy

New submission from Terry J. Reedy tjre...@udel.edu:

3.3.5. Emulating container types
object.__reversed__(self)
says in 3.0 and 3.1 and I assume in 2.x:
Objects should normally only provide __reversed__() if they do not
support the sequence protocol and an efficient implementation of reverse
iteration is possible.

The builtin sequences violate this because because they do support the
sequence and have __ reversed__ methods anyway.  And iterables that do
not support that protocol obviously *must* provide a method to be
reverse iterable.

I believe the point is that it is hard for Python code to beat the
C-coded version of the obvious

def __reversed__(self):
   for i in reversed(range(self.__len__)):
  yield self.__getitem__(i)

So I think the entry should say: Objects that support the sequence
protocol should only provide __reversed__ if they can provide an
implementation that is more efficient than the one provided by
reversed(). possibly followed by Objects that do not supposrt the
sequence protocol must provide __reversed__ to be reverse iterable.

[issue5992] spurious space after opening parenthesis when auto-completing

Terry J. Reedy tjre...@udel.edu added the comment:

What system are you using?  On Windows 3.0.1, standard interpreter window,
'h' 'e' 'tab' prints 'h' 'e' ' ' ' ' (making, with ' ', 8 chars.
Which is to say, there is no tab completion.

On IDLE, same brings up box and tab tab completes to 'help'

I presume you claim the dict example to be a bug in relation to A class

all of its abstract methods and properties are overridden.

There is the same difference with @abstractproperty

class C(metaclass=abc.ABCMeta):
@abc.abstractmethod
def f(self): return True

class C2(dict,metaclass=abc.ABCMeta):

[issue6017] Dict fails to notice addition and deletion of keys during iteration

2009-05-15 Thread Terry J. Reedy

Terry J. Reedy tjre...@udel.edu added the comment:

The OP reported a real mismatch between doc and behavior.  If the
behavior is not changed, I think the doc should be.  Other implementors,
reading the doc, might think that they do have to write code to track
changes.  From the doc, I thought that CPython did that.

So I suggest changing reopening and changing the doc to say
Changing the net size of the dictionary while using iteritems() will
raise a RuntimeError.  Same for iterkeys() and itervalues()[sp?]

Or remove the warning, as happened in the Py3 changeover to views, or
was that a mistake?

[issue6028] Interpreter crashes when chaining an infinite number of exceptions

2009-05-15 Thread Yury

Yury yury.sobo...@gmail.com added the comment:

The code you posted causes an infinite loop in the 2.x branch as well.
Anyway, I do not see how crashing is a desired result. An infinite loop
means the programmer made a mistake somewhere. A crash means the
interpreter did.

[issue858809] Use directories from configure rather than hardcoded

2009-05-15 Thread soundmurderer

soundmurderer soundmurde...@gmail.com added the comment:

I can confirm that --bindir and --libdir are broken in Python 2.6.2,
despite the fact that ./configure --help lists them as helpful options.
 At the very least, ./configure should complain if you're using options
that don't do anything!  That would be the easy fix.

Here is what I am doing:

./configure \
--prefix=/home/soundmurderer \
--bindir=/home/soundmurderer/bin/x86_64/Python-2.6.2 \
--libdir=/home/soundmurderer/lib/x86_64 

OK, now let's see the relevant section of the generated Makefile:

# Install prefix for architecture-independent files
prefix= /home/soundmurderer/auzilov

# Install prefix for architecture-dependent files
exec_prefix=${prefix}

# Install prefix for data files
datarootdir=${prefix}/share

# Expanded directories
BINDIR= $(exec_prefix)/bin
LIBDIR= $(exec_prefix)/lib
MANDIR= ${datarootdir}/man
INCLUDEDIR= ${prefix}/include
CONFINCLUDEDIR= $(exec_prefix)/include
SCRIPTDIR=  $(prefix)/lib

# Detailed destination directories
BINLIBDEST= $(LIBDIR)/python$(VERSION)
LIBDEST=$(SCRIPTDIR)/python$(VERSION)
INCLUDEPY=  $(INCLUDEDIR)/python$(VERSION)
CONFINCLUDEPY=  $(CONFINCLUDEDIR)/python$(VERSION)
LIBP=   $(LIBDIR)/python$(VERSION)

So, the --libdir and --bindir flags had no effect on LIBDIR and BINDIR,
and I wind up editing the Makefile by hand to get desired behavior.

[issue858809] Use directories from configure rather than hardcoded

2009-05-15 Thread soundmurderer

soundmurderer soundmurde...@gmail.com added the comment:

I tried applying nijel's 2.3.2 patch to Python 2.6.2 Makefile.pre.in,
then configure/make/install with --bindir and --libdir flags to
./configure.  It works in terms of producing the correct Makefile with
LIBDIR and BINDIR that I want, but I get problems after the make
install step when I launch the Python interpreter.  This is what happens:

Could not find platform independent libraries prefix
Could not find platform dependent libraries exec_prefix
Consider setting $PYTHONHOME to prefix[:exec_prefix]
'import site' failed; use -v for traceback
Python 2.6.2 (r262:71600, May 15 2009, 22:46:19)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
Type help, copyright, credits or license for more information.

I can work around bad imports and could not find libraries by adding
various subdirs of my desired LIBDIR to PYTHONHOME and PYTHONPATH.  But
the point is -- I thought that a *properly* installed Python
distribution should know where to find its own standard libraries??  I
should not have to hack PYTHONHOME and PYTHONPATH to get my local
install to work... right?

Once upon a time in 2.5.x days, I was able to do a local install using
only ./configure --prefix, and that's it.  No hacking PYTHONHOME or
PYTHONPATH that I recall.

How is the path to stuff like site.py getting encoded in the Python
installation?  Because I suspect that although nijel's patch may work
for generating makefiles that put binaries/libs in the right place, that
encoding step is still getting botched, requiring to manually set
PYTHONHOME and PYTHONPATH as a workaround.

Or maybe I am just confused.
