[issue15805] Add stdout redirection tool to contextlib

[Nick Coghlan]

Nick Coghlan added the comment:

I'd actually be inclined to make it the full trio: redirect_stdin, 
redirect_stdout, redirect_stderr.

Mostly because I don't see an especially compelling reason to privilege 
redirecting stdout over the other two standard streams, and the "pass in the 
stream name" approach is just ugly (e.g. we don't have 
"sys.stdstream['stdin']", we have sys.stdin).

There are plenty of command line apps that have both -i and -o options (to 
select input and output files), and "2>1" is a pretty common shell redirection.

Agreed that the general purpose nature of standard stream redirection makes it 
a good fit for contextlib, though.

[issue15805] Add stdout redirection tool to contextlib

[Raymond Hettinger]

Raymond Hettinger added the comment:

I like Nick's proposed variant and think it should go in contextlib, not the 
mocking library.  Redirection has a lot of use cases that has nothing to do 
with mocking-up test suites.  Contextlib is about general purpose 
context-managers that apply in many situations (the closing() context manager 
is a good example).

[issue16050] ctypes: callback from C++ to Python fails with Illegal Instruction call

[Pavel Maltsev]

New submission from Pavel Maltsev:

ppc_405, Linux 2.4, GCC 3.3.1

Python crashes on attempt to pass python callback function to custom C++ 
library under PowerPC 405. This happens because some versions of GCC (I guess 
below 4.1) doesn't raise __NO_FPRS__ flag if hard-floats is not supported, 
instead they use _SOFT_FLOAT. So we need to change

#ifndef __NO_FPRS__
to
#if (!defined(__NO_FPRS__) && !defined(_SOFT_FLOAT))

[issue7427] BadStatusLine is hell to debug

[Andrew Swan]

Andrew Swan added the comment:

I just got tripped up by this change, I wanted to catch the specific case of an 
http server closing a connection and assumed that the following would work:

try:
  resp = conn.getresponse()
except httplib.BadStatusLine, e:
  if len(e.line) == 0:
# server closed...
  else:
raise

That doesn't work since e.line holds the representation of the empty string 
instead of just holding the empty string.  I think the fragment above would be 
a much better way to write this test, the current alterntative of:
  if e.line == "''":
is hopelessly obscure.

Seems like the original fix should have been to add __repr__ to BadStatusLine 
rather than changing its contents.  Can this be revisited?

[issue16049] Create abstract base classes by inheritance rather than a direct invocation of __metaclass__

[Raymond Hettinger]

New submission from Raymond Hettinger:

Since inheritance is more commonplace and more easily understood than 
__metaclass__, the abc module would benefit from a simple helper class:

class ABC(metaclass=ABCMeta):
pass

>From a user's point-of-view, writing an abstract base call becomes simpler and 
>clearer:

from abc import ABC, abstractmethod

class Vector(ABC):

@abstractmethod
def __iter__(self):
pass

def dot(self, other):
'Compute a dot product'
return sum(map(operator.mul, self, other))

Notice that this class seems less mysterious because it inherits from ABC 
rather than using __metaclass__=ABCMeta.

Also note, it has become a reasonably common practice for metaclass writers to 
put the __metaclass__ assignment in a class and have it get inherited rather 
than requiring users do the metaclass assignment themselves.

[issue16001] small ints: cache string representation

[Terry J. Reedy]

Terry J. Reedy added the comment:

Small int caching saves both time and space. On a nearly fresh IDLE session:
>>> sys.getrefcount(0)
772
>>> sys.getrefcount(1)
854
>>> sum(sys.getrefcount(i) for i in range(-5, 257))
4878

While an interesting idea, I do not see the same gain here, and agree with 
Martin.

Array lookup *is* faster than string conversion:
>>> ti.repeat(setup = "ar = [str(i) for i in range(101)]", stmt = "ar[100]")
[0.058166605132757995, 0.03438449234832762, 0.034402937150259674]
>>> ti.repeat(setup = "S = str", stmt = 'S(100)')
[0.21833603908330446, 0.19469564386039195, 0.1947128590088596]

but
1: converting ints to decimal digits is nearly always done for output,
and conversion is blazingly fast compared to output, so output time will 
dominate.

>>> ti.repeat(setup = "S = str", stmt = 'S(100)', number = 20)
[1.0144641009901534e-05, 8.914987631669646e-06, 8.914987574826228e-06]
>>> ti.repeat(setup = "p = print", stmt = 'p(100)', number = 20)
...
[0.11873041968999587, 0.039060557051357137, 0.03859697769621562]

2. I presume the conversion of 0 - 9 to '0' - '9' within the conversion 
routines is already optimized. I don't see that 10 - 259 should be more common 
that 257 - 999, let alone more common than all higher ints. So the limited 
optimization can have only limited effect.

3. Much production numerical output is float or decimal rather than int. The 
3.3 optimization of ascii-only strings to bytes helped here.

[issue16023] IDLE freezes on ^5 or ^6 (Un-)Tabify Region with OS X Cocoa Tk 8.5

[Ned Deily]

Ned Deily added the comment:

Thanks for the additional information!  I can now reproduce a hang using just 
Ctrl-5 on a US keyboard input method.  Ctrl-5 is the default IDLE keyboard 
accelerator for the "Tabify Region" menu item under the "Format" menu cascade 
for an edit window.  With any current Python (2.7.3, 3.2.3, or 3.3.0rc3) linked 
with Cocoa Tk 8.5, using the Ctrl-5 accelerator key causes the hang, requiring 
a force quit.  Selecting the menu item with a mouse causes the "Tab Width" 
window to appear as expected.  Ctrl-5 seems to work properly with Pythons 
linked with either Carbon Tk 8.4 or with X11 8.5.  There is a similar hang 
behavior with Ctrl-6 "Untabify Region" using Cocoa Tk 8.5 as well.  Attached is 
an excerpt from a hang dump when running with a debug framework build of 3.3 
tip.

[issue16048] Tutorial-classes-remarks: replace paragragh

[Terry J. Reedy]

Terry J. Reedy added the comment:

Ian Kelly reminds me that instance.__xxx__ is only skipped by the internal 
machinery and not by direct accesses in user code. In the other hand, docs, 
official or otherwise, are filled with things like 'len(a) calls a.__len__', so 
I think something should be said that giving instances special method 
attributes does not have the effect one might expect.

[issue16048] Tutorial-classes-remarks: replace paragragh

[Terry J. Reedy]

Terry J. Reedy added the comment:

Peter Otten thought the first clause should instead be ""Data attributes and 
method attributes share the same namespace.", which is also true for a given 
object. This is a different intepretation of what the original author was 
getting at. The convention remark applies both within the class namespace and 
between class and instance namespaces.

[issue16048] Tutorial-classes-remarks: replace paragragh

[Terry J. Reedy]

New submission from Terry J. Reedy:

(from python-list thread "data attributes override method attributes?")

"9.4. Random Remarks

Data attributes override method attributes with the same name; to avoid 
accidental name conflicts, which may cause hard-to-find bugs in large programs, 
it is wise to use some kind of convention that minimizes the chance of 
conflicts. Possible conventions include capitalizing method names, prefixing 
data attribute names with a small unique string (perhaps just an underscore), 
or using verbs for methods and nouns for data attributes."

The first semi-sentence is wrong. Within a class or instance attribute space, 
later assignments replace earlier ones. Between them, instance attributes 
(usually) override class attributes. The exceptions are (some? all?) special 
methods. One suggestion on the thread is to replace the clause with 'Instance 
attributes override class attributes', as that is the apparent intent, but the 
exception needs to be noted.

The suggested Method and _data conventions are wrong in that they contradict 
PEP8 style. Peter Otten suggested that the convention suggestion be shortened 
to "To avoid name conflicts consider using verbs for methods and nouns for data 
attributes".

That's good to know. I did the whole thing manually and pasted the ./configure
environment from

   
http://buildbot.python.org/all/builders/RS6000%20AIX%207.1%20%5BSB%5D%203.x/builds/85/steps/configure/logs/stdio

to a file "build_env" in the home directory. Perhaps we can put that subroutine
in the file instead.

I think that's not so important right now. It's good to have more diversity
w.r.t compilers.

For the commercial compilers it might be good to switch to optimized builds
in order to see if there are either optimizer bugs or Python bugs that don't
show up with gcc.

[issue16002] AIX buildbot compile errors

[Trent Nelson]

Trent Nelson added the comment:

Hi Stefan, quick question: how did you invoke ./configure on the AIX box?  The 
reason for asking is that a7/arsenic is a little quirky, you need to run a zsh 
subroutine via `_xlc 12` to set up the right CC env (see 
~/buildslave/start.zsh).

Once you've done that, you need ./configure --without-gcc --with-pydebug to get 
the same environment as the build slave.

(I haven't set up a buildslave for gcc on that box.)

[issue16047] Tools/freeze no longer works in Python 3

[Marc-Andre Lemburg]

New submission from Marc-Andre Lemburg:

The freeze tool used for compiling Python binaries with frozen modules no 
longer works with Python 3.x.

It looks like it was never updated to the various path and symbols changes 
introduced with PEP 3149 (ABI tags) in Python 3.2.

Even with lots of symlinks to restore the non-ABI flagged names, freezing fails 
with a linker error in Python 3.3:

Tools/freeze> python3 freeze.py hello.py
Tools/freeze> make
config.o:(.data+0x38): undefined reference to `PyInit__imp'
collect2: ld returned 1 exit status
make: *** [hello] Error 1

[Ezio Melotti]

Ezio Melotti added the comment:

Before adding tests (and possibly documentation) for edge cases like

> int(base='foo')  # no exception; returns 0

I'd take a look at what other implementations do.  If they do something 
different we might still decide to keep the tests and mark them as 
cpython-specific, but I would refrain to document them.

That's difficult to test, since the Tools/freeze/ tool no longer works
in Python 3.3. I'll open a separate issue for that.

[issue16035] Segmentation fault in test suite of apsw

[Antoine Pitrou]

Antoine Pitrou added the comment:

The cause for Stefan's traceback looks quite clear:

Connection_createaggregatefunction() release the GIL (through the 
PYSQLITE_CON_CALL macro) before calling into sqlite3_create_function_v2, which 
itself calls the destructor for the old aggregate function, aka. 
apsw_free_func(), which calls Py_DECREF without re-acquiring the GIL.

So apsw needs to sanitize its callbacks implementation here.

[issue16027] pkgutil doesn't support frozen modules

[Nick Coghlan]

Nick Coghlan added the comment:

Can you confirm this problem still exists on 3.3? The pkgutil emulation isn't 
used by runpy any more - with the migration to importlib, the interface that 
runpy invokes fails outright if no loader is found rather than falling back to 
the emulation (we only retained the emulation for backwards compatibility - 
it's a public API, so others may be using it directly).

I have a feeling that there may still be a couple of checks which are 
restricted to PY_SOURCE and PY_COMPILED that really should be allowing 
PY_FROZEN as well.

[issue16027] pkgutil doesn't support frozen modules

[Marc-Andre Lemburg]

Marc-Andre Lemburg added the comment:

Here's the fix we're applying in pyrun to make -m imports work at least for 
top-level modules:

--- /home/lemburg/orig/Python-2.7.3/Lib/pkgutil.py  2012-04-10 
01:07:30.0 +0200
+++ pkgutil.py  2012-09-24 22:53:30.982526065 +0200
@@ -273,10 +273,21 @@ class ImpLoader:
 def is_package(self, fullname):

 return self.etc[2]==imp.PKG_DIRECTORY

 def get_code(self, fullname=None):
+if self.code is not None:
+return self.code
+fullname = self._fix_name(fullname)

 fullname = self._fix_name(fullname)
 if self.code is None:
 mod_type = self.etc[2]
 if mod_type==imp.PY_SOURCE:
 source = self.get_source(fullname)

This makes runpy work for top-level frozen modules, but it's really only 
partial solution, since pkgutil would need to get such support in more places.

We also found that for some reason, runpy/pkgutil does not work for frozen 
package imports, e.g. wsgiref.util. The reasons for this appear to be deeper 
than just in the pkgutil module. We don't have a solution for this yet. It is 
also not clear whether the problem still exists in Python 3.x. The __path__ 
attribute of frozen modules was changed in 3.0 to be a list like for all other 
modules, however, applying that change to 2.x lets runpy/pkgutil fail 
altogether (not even the above fix works anymore).

[issue16045] create some unit tests for built-in int()

[Chris Jerdonek]

New submission from Chris Jerdonek:

The built-in function int() does not seem to have any basic unit tests (e.g. in 
test_builtin).  It would be good to add some.

Some cases (including edge cases) for possible inclusion:

int()
int(base='foo')  # no exception; returns 0
int(x=5)
int(x=5, base=10)  # raises TypeError
int(5.8)  # test truncation towards zero
int(-5.8)  # ditto
int('5.8')  # raises ValueError

Both positional and keyword argument combinations should be tested.

I couldn't find what you're talking about.
If I look at AbstractHTTPHandler.do_request_, it actually mandates a 
Content-Length header for POST data (hence no chunked encoding).

[issue2126] BaseHTTPServer.py fails long POST from IE

[Antoine Pitrou]

Antoine Pitrou added the comment:

Reading the original issue:

"it appears that IE is sending 2 extra bytes ('\r\n') after 
the request data.  and if you don't read those two extra 
bytes off, the window's socket handling gets messed up.

the result is that a partial response is returned and the 
socket closed.  IE tries to recover by re-POST'ing (which 
is behavior specified in the HTTP/1.1 RFC)... only they 
seem to add an embedded NULL the second time through, and 
the original socket problem happens again anyway."


... I have a hard time believing IE is still broken today. I'd rather close 
this issue, please re-open if you can reproduce with a recent IE.

[issue16044] xml.etree.ElementTree.Element: append method iterator param is broken

[Ronald Oussoren]

Ronald Oussoren added the comment:

Use the extend method to add multiple elements. Both the source and 
documentation indicate that 'append' is used for appending a single item and 
'extend' for appending multiple items (just like with list).

IMHO this is not a bug.

As an aside: when you import xml.etree.cElementTree you get a faster 
implementation of the same interface, and this (C-based) implementation does 
validate arguments.
