[issue24064] Make the property doctstring writeable

I don't see a need for this restriction.  Even regular classes don't enforce 
this.

[issue24032] urlparse.urljoin does not add query part

[Martin Panter]

Martin Panter added the comment:

This is not how URL joining is meant to work. For example if the base URL “. . 
./foo.php?param=10” produces a HTML file with a relative link to “bar.php”, the 
parent path should be joined on, but not the query part.

I understand the Python implementation is meant to more or less follow the RFC. 
See the second example at 
 which is the same form 
as your case, and shows the query part being removed:

Base URI: http://a/b/c/d;p?q
Relative reference: "g"
Target URL: "http://a/b/c/g";

There are occasionally cases where keeping the base query, or even joining two 
sets of query parameters together, is desirable. But these cases are rare and 
urljoin() is not meant to handle them.

[issue24172] Errors in resource.getpagesize module documentation

[Mahmoud Hashemi]

New submission from Mahmoud Hashemi:

The resource module's description of resource.getpagesize is woefully 
misguiding. Reproduced in full for convenience:

resource.getpagesize()

Returns the number of bytes in a system page. (This need not be the same as 
the hardware page size.) This function is useful for determining the number of 
bytes of memory a process is using. The third element of the tuple returned by 
getrusage() describes memory usage in pages; multiplying by page size produces 
number of bytes.

Besides being vague by not referring to the third element as ru_maxrss, the 
peak RSS for the process (i.e., not the current memory usage), tests on Linux, 
Darwin, and FreeBSD show the following:

  * Linux: ru_maxrss is in kilobytes
  * Darwin (OS X): ru_maxrss is in bytes
  * FreeBSD: ru_maxrss is in kilobytes (same as Linux)

Knowing the page size is probably useful to someone, but the misinformation has 
definitely sent more than one person down the wrong path here. Additionally, 
the correct information should be up in the getrusage() method documentation, 
closer to relevant field descriptions.

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

[Nick Coghlan]

Nick Coghlan added the comment:

A bit more detail on the patch-as-merged: it has all of Yury's new tests, but 
the actual bug turned out to just be a missing INCREF/DECREF pair in 
WITH_CLEANUP_START and WITH_CLEANUP_FINISH.

In the success case the reference counting errors cancelled each other out 
without causing a problem, as there was always a second live reference to the 
exception object on the stack.

However, in the case where the awaitable threw an exception the standard 
exception handling machinery took care of removing the saved exception from the 
stack, and correctly decremented the reference count, which then caused 
problems due to the missing INCREF in WITH_CLEANUP_START.

[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.

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.

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

[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 ``1234``, 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.

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

[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.

[issue23290] Faster set copying

[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

[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

[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.

[issue24170] IDLE crashes when I press ^ key

[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).

Terry J. Reedy added the comment:

Does not happen on Windows. Please start Idle with "python -m idlelib" in a 
console and report any error traceback you see.  Replace 'python' with 
'python3' or 'py -3' as needed to start 3.x.  (I am not familiar with osx

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

[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.

[issue24156] test.test_ssl.ThreadedTests unit test failed

[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

[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).

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.

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):

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

[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 .

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.

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

[Kurt Rose]

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

('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()

>>> socket.create_connection( ('google.com', 2**16 + 80) ).getsockname()
('10.225.89.86', 56452)

Java's stdlib gives a proper error message:

The .NET runtime also rejects invalid ports:

Traceback (most recent call last):

ValueError: Specified argument was out of the range of valid values.

IronPython by extension rejects the invalid port:

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

However, Jython recreates the behavior of CPython:

(u'10.225.89.86', 63071)

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

[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.

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

[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) )


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, "O&i: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)

[issue23290] Faster set copying

[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.

[issue24156] test.test_ssl.ThreadedTests unit test failed

[Roman Rader]

Roman Rader added the comment:

You're right, it does not reproduces on any machine. I'm using Arch Linux, 
still trying to figure out the repro steps.

My hosts file doesn't contain such entries for localhost, it's pretty standard. 
If I disable my external network interface, it retrieves my second IP from 
virtual interface. And only when I disable all interfaces, I can get 127.0.0.1 
on source in IP packet.

The problem is, even if I enforce client to bind to "127.0.0.1", it substitutes 
as well (see https://gist.github.com/rrader/3e575cde56827b1f74a1).

strace is clean, Python calls all kernel functions with 127.0.0.1 IP. So, I 
suppose, the problem not in the Python code itself, but somewhere deeper 
(however it can be lack of some flags?)

[issue23895] PATCH: python socket module fails to build on Solaris when -zignore is in LDFLAGS

[R. David Murray]

R. David Murray added the comment:

Do you know anyone else using solaris who could do a review (ie: confirm that 
your patch makes sense and works for them)?  It looks like jcea, who is our 
only current committer who uses Solaris as far as I know (well, OpenIndiana), 
hasn't had time to look at this.

On the other hand, it isn't 100% clear to me that this is appropriate.  I'm not 
(yet) experienced enough with the internals of our build system to be the one 
to make the call, but it seems to me that you can support -z ignore by 
modifying your Modules/Setup file, so it may not be appropriate to inject 
solaris specific support in setup.py for an option that isn't normally used.
