[issue24166] ArgumentParser behavior does not match generated help

2015-05-12 Thread Benjamin Schubert

Benjamin Schubert added the comment:

Thanks a lot for this explanation ! It is more clear now for why it is not 
working.

However, I would suggest that the ArgumentParser should still try to match 
anything the subparser could not, or would this be too complicated ?

Moreover, if this scheme is not feasible, I would suggest modifying the 
documentation, or having a warning, or something to let people know. If this is 
possible.

[issue24166] ArgumentParser behavior does not match generated help

2015-05-12 Thread Benjamin Schubert

Benjamin Schubert added the comment:

I solved my problem by subclassing the ArgumentParser and redefining parse_args 
as follow :

class MultipleArgumentParser(ArgumentParser):
def parse_args(self, args=None, namespace=None):
args, argv = self.parse_known_args(args, namespace)

if not argv:
return args

# save old actions, before rerunning the parser without the 
_SubParsersActions
self._old_actions = self._actions.copy()
self._actions = [action for action in self._old_actions if not 
isinstance(action, _SubParsersAction)]

# parse the remaining command line
args2, argv2 = self.parse_known_args(argv, None)

self._actions = self._old_actions.copy()

if argv2:
msg = _('unrecognized arguments: %s')
self.error(msg % ' '.join(argv2))

for key, value in vars(args2).items():
if isinstance(value, collections.Iterable):
setattr(args, key, [value for value in 
itertools.chain(getattr(args, key), value)])

return args


I know this is not generic enough and not cleanly done. However, would this be 
an interesting addition to the argumentparser ? If so, I can try to make a 
generic implementation, which would allow having multiple arguments after a 
subparser which did not match them

[issue23290] Faster set copying

2015-05-12 Thread Raymond Hettinger

Raymond Hettinger added the comment:

I don't like the patch as-is (comment change is wrong, test in the inner-loop 
making the common case pay for a short-cut for the uncommon case).  As I said 
before, the basic idea is good and I will very likely include some variant of 
this for Python3.5.

I marked this as low priority so I can work on other things (such as deque 
slicing) before the feature freeze and will come back to this after beta 1.  
Please remain calm.  My development time is limited but this is something I do 
want to get done.

[issue24169] sockets convert out-of-range port numbers % 2**16

2015-05-12 Thread Kurt Rose

Kurt Rose added the comment:

I was incorrect -- the result of getsockname() appears to be some garbage port:

 socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
('10.225.89.86', 56446)
 socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
('10.225.89.86', 56447)
 socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
('10.225.89.86', 56448)
 socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
('10.225.89.86', 56449)
 socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
('10.225.89.86', 56450)
 socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
('10.225.89.86', 56451)
 socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
('10.225.89.86', 56452)

Java's stdlib gives a proper error message:

 java.net.Socket(google.com, 2**16 + 80)
Traceback (most recent call last):

java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: port out

The .NET runtime also rejects invalid ports:

Traceback (most recent call last):
  File stdin, line 1, in module
ValueError: Specified argument was out of the range of valid values.
Parameter name: port

IronPython by extension rejects the invalid port:

 socket.create_connection( ('google.com', 2**16 + 80) )
Traceback (most recent call last):
  File stdin, line 1, in module
ValueError: Specified argument was out of the range of valid values.
Parameter name: port

However, Jython recreates the behavior of CPython:

 socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
(u'10.225.89.86', 63071)

[issue2704] IDLE: Patch to make PyShell behave more like a Terminal interface

2015-05-12 Thread Sean Wolfe

Sean Wolfe added the comment:

Windows 7 patch test successful:


https://bugs.python.org/issue2704

* install python 2.7.8 fresh on W7
* check idle terminal functionality
-- should not show terminal changes from 2704:
- up arrows move cursor
- typing out of focus has no effect
- clicking above the prompt, then typing, does not move cursor to the prompt 
and begin typing


* install Terminal.py in idlelib
* apply PyShell.py.patch

* click out of focus and type
-- cursor returns to prompt + text appears
* backspace
-- backspace deletes text on prompt line

* press up arrow
-- cursor does not move up
-- bell sounds as there are no previous commands

* enter a few commands, then use up/down keys to navigate history
-- up and down browse through history

There seems to be a bell command in the history as I cycle through commands 
when I cross from earliest to latest.

[issue23290] Faster set copying

2015-05-12 Thread Raymond Hettinger

Raymond Hettinger added the comment:

I looked at the patch again and it is in pretty good shape.

Please hoist the conditionals out of the loop (for intelligibility and to let 
the compiler in-line more effectively).  Also, let's remove the dump and 
clear variable names in favor of comments that explain the conditionals (to 
introducing new terminology to the module). 

If you want, I'll take a crack at it in the next couple of days.

Sorry, dumb mistake on my part.  I should have been calling getpeername(), not

In that case the result is 80:
 socket.create_connection( ('google.com', 2**16 + 80) ).getpeername()
('74.125.239.41', 80)

The random ports were the client-side ephemeral ports.

2015-05-12 Thread Ned Deily

Ned Deily added the comment:

Thanks for the additional info.  I don't know what possible configuration 
options might affect this other than that I would expect to see 127.0.0.1 as 
the primary IPv4 address on the loopback interface, like:

# ifconfig
[...]
loLink encap:Local Loopback
  inet addr:127.0.0.1  Mask:255.0.0.0
  inet6 addr: ::1/128 Scope:Host
  UP LOOPBACK RUNNING  MTU:65536  Metric:1
[...]

Since this does seem to be unique to your configuration, I'm going to close 
this issue for now.  If you do discover the root cause and it appears to be 
something that might be seen by other users and, thus, should be handled in the 
test suite, please re-open.

[issue24169] sockets convert out-of-range port numbers % 2**16

2015-05-12 Thread Kurt Rose

New submission from Kurt Rose:

This appears to affect all versions of Python.  In a behavior inherited from C, 
TCP ports that are  2 bytes are silently truncated.

Here is a simple reproduction:

 socket.create_connection( ('google.com', 2**16 + 80) )
socket.socket object, fd=408, family=2, type=1, proto=0

Needs more investigation, but one likely place to make the fix is here:
https://hg.python.org/cpython/file/9d2c4d887c19/Modules/socketmodule.c#l1535

if (!PyArg_ParseTuple(args, Oi:getsockaddrarg,
  idna_converter, host, port))

Instead of parsing port with i, use H.  This is a deep change to the behavior, 
but I think it is very unlikely that users intentionally mean to pass a TCP 
port  2**16.  More likely, this is silently swallowing errors. 

There no indication that the passed port parameter is not being used for the 
actual TCP communication (which is physically impossible because TCP only has a 
2 byte port field).

In fact, the socket will continue to lie to the user and obfuscate the actual 
port being used if getsockname() is called:

 socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
('10.225.89.86', 54899)

[issue2704] IDLE: Patch to make PyShell behave more like a Terminal interface

2015-05-12 Thread Sean Wolfe

Sean Wolfe added the comment:

successfully tested on Linux in 2014

Hello folks, FYI I also installed this patch on Lubuntu linux in 2014 on a 
series of computers at a lab where I mentor. I don't have the documentation for 
those specific tests, but I did follow the outline above, and it was done.

So, IMO we can call this tested on W7, Linux and OSX 10.9.3, for Python 2.7 .

[issue24169] sockets convert out-of-range port numbers % 2**16

2015-05-12 Thread R. David Murray

R. David Murray added the comment:

You pegged it when you said the behavior is inherited from C.  Technically this 
isn't a bug in Python, since the socket module is a set of (mostly) thin 
wrappers around the C.

Enhancing CPython to do the check is not a bad suggestion, especially since it 
seems that other languages and implementations do so.  We won't fix this in a 
maintenance release, though, since it would pointlessly break working code 
(even if that code is technically buggy).

[issue23290] Faster set copying

2015-05-12 Thread Antoine Pitrou

Antoine Pitrou added the comment:

Le 12/05/2015 20:55, Raymond Hettinger a écrit :
 
 Optimizations aren't new features.  We can still tweak the implementation 
 through-out the betas.

Not really. The period after the first beta is for fixing bugs, not for
risking introducing new bugs.

[issue24171] httplib

2015-05-12 Thread JitterMan

New submission from JitterMan:

In python2.7.9, httplib.py, on line 780, makes a call to:

line = response.fp.readline(_MAXLINE + 1)

This ends up calling a function defined on line 1362 in the same file:

def readline(self):

Notice the argument mismatch. The call passes two arguments, but the function 
defines only one. This can be 'fixed' by changing the definition to:

def readline(self, size=None):

[issue24170] IDLE crashes when I press ^ key

2015-05-12 Thread Ned Deily

Ned Deily added the comment:

Unless I'm very much mistaken, this is another instance of the old Cocoa Tk 
problem documented here (http://sourceforge.net/p/tktoolkit/bugs/2722/) and 
referred to in https://www.python.org/download/mac/tcltk/.  It's not like a 
normal TclError in that it causes the embedded Tcl interpreter used by Python 
to hard crash with no chance of recovery.  This is why we strongly recommend 
people not use older versions of Cocoa Tk as, unfortunately, are still shipped 
by Apple with the latest versions of OS X.  The problem has been fixed in more 
recent versions of Cocoa Tk such as those shipped by ActiveState and which the 
python.org installer will use if installed (and will warn about if not 
installed).

[issue17849] Missing size argument in readline() method for httplib's class LineAndFileWrapper

2015-05-12 Thread JitterMan

JitterMan added the comment:

I ran into this problem when I gave https_proxy an invalid value:

export https_proxy=http://foo.com

No divine intervention required. I was just trying to determine what message 
was printed with the proxy environment variable was set incorrectly.

Perhaps that will help you develop a more reasonable testcase.

Yes, of course, I think we shouldn't drop support of these format units. But

[issue23290] Faster set copying

2015-05-12 Thread Raymond Hettinger

Raymond Hettinger added the comment:

Attaching a variant with several fix-ups (mostly minor):

* Changed the order of the three sections to go from 
most-restricted-most-optimized to the general-fall-through case.  The downside 
is that we test so-fill==0 twice.  The upside is that it corresponds to my way 
of thinking about the logic.

* Put the fill/used increments in the same order as the rest of the file.

* Loop over other_entry++ instead of using indexing.  This corresponds to my 
way of thinking about the entries and gives the compiler a stronger hint that 
it can avoid the indexing overhead.

* Removed the unnecessary dummy check from the direct_pointer_copy case.

* Switch the order of the same size and no dummies tests in the insert_clean 
case.

* Revise the comments to be clearer about the requirements for each case.

* Move the sometimes unnecessary hash variable assignments inside the 
conditional.

[issue24169] sockets convert out-of-range port numbers % 2**16

2015-05-12 Thread Kurt Rose

Kurt Rose added the comment:

Totally agree this needs to be managed carefully.  My goal here was just to 
raise awareness and see if there is consensus that the behavior should be 
changed.

I came across this because an upstream process had a bug which led to 
impossible TCP ports being specified.  So, for my use case it would have been 
better if create_connection() had rejected the invalid data.

If we are talking about enhancements to the socket module, it would also be 
nice if errors included the address :-)

[issue24166] ArgumentParser behavior does not match generated help

2015-05-12 Thread paul j3

paul j3 added the comment:

Look at http://bugs.python.org/issue9338
argparse optionals with nargs='?', '*' or '+' can't be followed by positionals

That has a proposed patch that wraps the main argument consumption loop in 
another loop.

The current loop alternatively consumes optionals and positionals until the 
argv list is done.  The `consume_loop` method in that patch tries various 
allocations of argv strings between optionals and positionals.  It performs 
'dry' runs until it finds something that consumes most of the strings, and then 
does the actual parsing with changes to the namespace.

The idea might be adapted to work with subparsers, paying attention, as you do, 
to the 'extras' from parse_known_args.  But it might be hard to reliably 
perform a 'dry' run when subparsers are involved.

I suspect that any change along this line will be too complex to ever be the 
default behavior.  The chances of messing with backward compatibility are just 
too great.  It might pass as an alternative parsing call.

[issue21708] Deprecate nonstandard behavior of a dumbdbm database

2015-05-12 Thread Serhiy Storchaka

Serhiy Storchaka added the comment:

Warnings are not raised by default. They are raised only when the database is 
opened with the 'r' mode and then modified.

The earlier we start deprecation period, the earlier we could add true 
read-only and update existing modes to dbm.dumb.

[issue24017] Implemenation of the PEP 492 - Coroutines with async and await syntax

2015-05-12 Thread Yury Selivanov

Yury Selivanov added the comment:

 Is there are a specific reason this implicit exception handler can't be 
 decomposed and implemented using the same opcodes as are used to implement 
 explicit exception handlers?

I don't think it's possible to replace ASYNC_WITH_CLEANUP_EXCEPT opcode with 
some combination of existing opcodes.

What might be possible is to implement 'async with' without using 
WITH_CLEANUP_* opcodes at all.  Let me try that.

[issue24017] Implemenation of the PEP 492 - Coroutines with async and await syntax

2015-05-12 Thread Nick Coghlan

Nick Coghlan added the comment:

I'm going to dig into this one locally, as it sounds to me like something may 
be going wrong with the refcounts in the complex stack manipulation involved in 
WITH_CLEANUP. It seems plausible that there's a genuinely missing incref/decref 
pair somewhere in the non-exceptional path, which the proposed new opcode is 
working around.

Avoiding WITH_CLEANUP entirely in the async case also sounds like a plausible

[issue24017] Implemenation of the PEP 492 - Coroutines with async and await syntax

2015-05-12 Thread Yury Selivanov

Yury Selivanov added the comment:

Nick, Guido,

Attached is a patch that fixes a refleak in 'async with' implementation.

The problem is related to WITH_CLEANUP_START/WITH_CLEANUP_FINISH opcodes.

For regular 'with' statements, these opcodes go one after another (essentially, 
it was one opcode before 'async with').

For 'async with' statements, we have a GET_AWAITABLE/YIELD_FROM pair between 
them.

Now, if an error occurred during running a GET_AWAITABLE or a YIELD_FROM 
opcode, WITH_CLEANUP_FINISH was unreachable.  All blocks were correctly unwound 
by the eval loop, but exception object got too many DECREFS.

My solution is to continue using WITH_CLEANUP_START/WITH_CLEANUP_FINISH 
opcodes, but use SETUP_EXCEPT to guard them and nested YIELD_FROM and 
GET_AWAITABLE.

In case of an exception, I propose to use another new opcode -- 
ASYNC_WITH_CLEANUP_EXCEPT.  It unwinds the block set up by SETUP_EXCEPT, 
restores exception, NULLifies a copy of exception in the stack and does 'goto 
error', letting eval loop do the rest.

./python.exe -m test -R3:3 test_coroutines with this patch reports no 
refleaks.  I also updates test_coroutines with a lot of new 'async with' tests, 
I think that I got all usecases covered.

Please take a look at the patch, I want to commit it as soon as possible.

[issue24079] xml.etree.ElementTree.Element.text does not conform to the documentation

2015-05-12 Thread Martin Panter

Martin Panter added the comment:

Another problem with tostring() is that it seems you have to call it with 
encoding=unicode. Perhaps it would be better to suggest code like 
.join(element.itertext())?

I would also improve on Jérôme’s version by making the None case more explicit. 
And perhaps both attributes can be defined together, rather than giving a 
half-hearted definition linking between them:

.. attribute:: text
.. attribute:: tail

   The *text* attribute holds any text between the element's begin tag and the 
next tag. The *tail* attribute holds any text between the element's end tag and 
the next tag. These attributes are set to ``None`` if there is no text. For 
example, in the XML data ``ab1c2d/3/c/b4/a``, the *a* element has 
``None`` for both *text* and *tail* attributes, the *b* element has *text* 
``1`` and *tail* ``4``, the *c* element has *text* ``2`` and *tail* 
``None``, the *d* element has *text* ``None`` and *tail* ``3``.
   
   To collect the inner text of an element, use :meth:`itertext`, for example 
``.join(element.itertext())``.
   
   Applications may store arbitrary objects in these attributes.
