[issue19524] ResourceWarning when urlopen() forgets the HTTPConnection object

[Martin Panter]

Martin Panter added the comment:

Added a new test for the invalid response case. Now both tests are included in 
test2.patch.

I separated the actual fix into a separate close3.4.patch (refreshed for the 
3.4 branch). This way it is easier for me to make sure the tests work before 
applying the fix, but it should be easy to combine the patches again if you 
prefer it that way.

[issue3068] IDLE - Add an extension configuration dialog

[Tal Einat]

Tal Einat added the comment:

Bah, my original message was truncated!

I could use some help figuring out how to test with various Tk versions. I have 
a Mac with OSX 10.8, and I've found the "IDLE and tkinter with Tcl/Tk on Mac OS 
X" page[1], but I'm still not sure how to actually go about installing and 
running IDLE with the different versions.

[issue21988] Decrease iterating overhead in timeit

[Tim Peters]

Tim Peters added the comment:

I'm afraid "microoptimizations" aren't worth measuring to begin with, since, 
well, they're "micro" ;-)  Seriously, switch compilers, compilation flags, or 
move to a new release of a single compiler, and a micro-optimization often 
turns into a micro-pessimization.  If I _want_ to measure something unrolled, 
I'll unroll it myself.  But since I almost never want to measure something 
unrolled anyway, an option to do so would just be "yet another attractive 
nuisance" to me.

[issue18320] python installation is broken if prefix is overridden on an install target

[Ned Deily]

Ned Deily added the comment:

The problem you see is being caused by trying to override "prefix" on the 
"altinstall" or "install" targets.  While Makefiles for many products will let 
you do that successfully, you really can't do that with Python's.  
Unfortunately, the values for "prefix" and "exec_prefix" specified (or 
defaulted) on ./configure are used during the main make build targets.  This 
includes the customization of the shebangs lines for the scripts like "idle" 
and "pydoc".  If you change the "prefix" value for the "install" phase, most 
files do get installed at the changed location but there are various places 
where the original, configured values remain.  You can see this if you run 
"python -m sysconfig" and examine the prefix values.  One result is that any 
scripts installed via Distutils (including using pip) will get installed to the 
configured location, e.g. default /usr/local/bin.  This also affects ensurepip 
(new in 3.4): the pip and easy_install scripts are installed in the configured 
value of p
 refix, e.g. /usr/local/bin, rather than the overridden value.  That's not good.

Changing prefix on the install targets seems like a fairly esoteric use case 
and one with an easy workaround: don't do that, use ./configure 
--prefix=/path/to instead.  I don't think it's worth trying to support since it 
may require some major Makefile work to get all the right dependencies.  But, 
at a minimum, it would be worth adding a test to the various install targets 
that would check and abort if prefix is attempted to be changed so you don't 
end up with a silently broken installation.

[issue16509] sqlite3 docs do not explain check_same_thread

[Thomas Kluyver]

Thomas Kluyver added the comment:

This page also looks relevant: sqlite can be compiled or used in three 
different threading modes. Presumably Python compiles/initialises it in the 
serialised mode, which makes it safe to use a connection from different threads.

[issue16509] sqlite3 docs do not explain check_same_thread

[Thomas Kluyver]

Thomas Kluyver added the comment:

The module docs do mention "Older SQLite versions had issues with sharing 
connections between threads." Presumably that means that sharing the connection 
between threads is safe so long as you're not using 'older versions', but it 
would be nice to have some more clarity about how old those versions are.

[issue13041] argparse: terminal width is not detected properly

[paul j3]

paul j3 added the comment:

The latest patch, using _shutil.get_terminal_size(), looks fine.  

It lets environ['COLUMNS'] have priority over the end user's terminal width, as 
demonstrated by the change to test_argparse.  test_argparse doesn't test 
changing the actual terminal size, but I imagine that would be a pain to 
implement.

Ah, I think I was mistaken about some things when I made the first patch but it 
looks like TPen have a few methods that don't work as you'd expect. Since 
_colorstr isn't implemented on TPen fillcolor and pencolor pen don't work as 
intended when you call them directly from TPen. Jesstess suggested raising a 
NotImplementedError on these functions. Would that be a good change to make?

Terry J. Reedy added the comment:

3.3 only gets security fixes.

This looks to be a linux altinstall installation problem rather than an idle 
problem. Idle and pydoc only start if Python starts first.  One way to start 
idle is to start Python and then enter 'import idlelib.idle'.

How did you start python that worked.
How did you try to start idle or pydoc that failed.

[issue21995] Idle: pseudofiles have no buffer attribute.

[Terry J. Reedy]

New submission from Terry J. Reedy:

sys.stdin on 3.4.1 is also 'missing' (among public names) 'line_buffering' 
(True) and 'mode' ('r'). It seems that these could be trivially added, so the 
focus of this issue is 'buffer'. The associated 
.detach method is a no-op, (It is also a bit dangerous for interactive 
operation.)

3.4.1 Console interpreter:
>>> import sys; b = sys.stdin.buffer.readline()
a line
>>> b
b'a line\r\n'

3.4.1 Idle:
>>> import sys; b = sys.stdin.buffer.readline()
Traceback (most recent call last):
  File "", line 1, in 
import sys; b = sys.stdin.buffer.readline()
AttributeError: 'PseudoInputFile' object has no attribute 'buffer'

https://docs.python.org/3/library/sys.html#sys.stdin
presents the idiom. It also warns (too narrowly -- 'if you are writing a 
library ...') that it might not.

As far as I could find, the Idle doc does not mention the standard streams, let 
alone Idle specific limitations.

I intentionally wrote the title as a statement of a problematical situation, 
rather than as a proposed solution, as there are two: change code and change 
doc.

Code: add .buffer as a bytes-oriented Pseudofile.

Doc: at least mention that standard streams are replaced by objects that ship 
text between processes, and use gui for input and display, and the consiquences 
of this.

[issue21993] counterintuitive behavior of list.index with boolean values

No, it's not that simple and I don't think this should be closed:

In my example:
>>> l = ['a', '', {}, 2.7, 1, 0, False, True]
>>> l.index(True)
4
>>> l.index(False)
5

if using __eq__ consistently, you'd expect the first call to return 0 and the 
second 1 (since the empty string evaluates to False).

[Wolfgang Maier]

New submission from Wolfgang Maier:

>>> l = [False, True]

1

0

good, but:

>>> l = ['a', '', {}, 2.7, 1, 0, False, True]
>>> l.index(True)
4
>>> l.index(False)
5

Apparently, True and False get converted to int in comparisons to ints.
I would expect items to be compared either by:

a) object identity or
b) __eq__

but not this inconsistently.

Best,
Wolfgang

Oh, that's a good point, I hadn't thought of that.  Maybe I can come up with a

[issue13540] Document the Action API in argparse

[Jason R. Coombs]

Jason R. Coombs added the comment:

That's interesting that there's activity on this again. I had forgotten I'd 
filed it. It's particularly timely, as I just yesterday had this experience 
again. I looked at the documentation and found it inadequate for me to 
understand how to implement a custom action, so I went to the source to figure 
it out. The action I ended up creating was this one:

class SandboxAction(argparse.Action):
def __init__(self, *args, **kwargs):
super().__init__(*args, nargs=0, **kwargs)

def __call__(self, *args, **kwargs):
cls.use()

Where 'cls' is defined in the same scope where SandboxAction was defined. I'm 
not sure if my documentation patch would have been sufficient to allow me to 
write that Action without consulting the source, but this example represents 
another case where that should be possible.

I haven't made any tweaks to the patch as a result of Steven's comments, so I 
probably could do that. I don't now when I'll have the time to do that, but 
I'll keep a tab to remind me to revisit the issue again.

[issue21059] idle_test.test_warning failure

[Zachary Ware]

Zachary Ware added the comment:

I believe I eventually figured out the reason for the failure, it had to do 
with the fact that the Tcl/Tk DLLs were copied into PCbuild to avoid adding 
..\tcltk[64]\bin to PATH and the persistent issue that tkinter._fix changes 
environment variables to make init.tcl findable, while regrtest unsets those 
variables at the end of each test.  The issue is successfully worked around in 
test[-amd64].bat, and should be fixed by #20035 (once reviewed :)).

Closing this issue.

[issue15968] Incorporate Tcl/Tk/Tix into the Windows build process

[Zachary Ware]

Zachary Ware added the comment:

Terry: the difference you saw between using regrtest and using unittest.main 
from the interactive prompt was because of regrtest.saved_test_environment: 
tkinter._fix sets environment variables at the beginning of one test which are 
cleared at the end by saved_test_environment, and not reset at the beginning of 
the next.  #20035 has my preferred fix for that situation.

Mark: Glad this helped, and thanks for the ping.

[issue19806] smtpd crashes when a multi-byte UTF-8 sequence is split between consecutive data packets

[R. David Murray]

R. David Murray added the comment:

No, I think the error return is better.  Crashing the server on bad input data 
(which, worse, could be perfectly valid if the server were standards compliant) 
is a bad thing, I think.  That is, if someone has an application that actually 
works with decode_data=True, I think it is better if it doesn't crash just 
because of different input data or TCP packet boundaries, as long as the error 
is reported.  I'm willing to be convinced otherwise, but that's how I'm leaning.

[Zachary Ware]

Zachary Ware added the comment:

I think a pyvenv.exe would be overkill, but I think it would be reasonable to 
install the pyvenv script to \Scripts rather than 
\Tools\Scripts, possibly as both 'pyvenv.py' and 'pyvenv-X.Y.py'.  
Personally, I still prefer 'py -3 -m venv', but I understand the argument that 
that's not enough.

[issue21918] Convert test_tools to directory

Committed, thanks for the reviews!

I had modeled load_tests after test_json's load_tests.  The idiom used in 
test_email causes a warning from regrtest about sys.path being modified, so I 
modified the idiom slightly and used that.  I have declined to backport the 
patch to 2.7; it's more trouble than it's worth to me.

_fields_ = [
("uint8_0", ctypes.c_uint8, 8),
("uint8_1", ctypes.c_uint8, 8),
("_ignore", Empty),
("uint16_0", ctypes.c_uint16, 1),
("uint16_1", ctypes.c_uint16, 15),
]

for f in Struct._fields_:
print f[0], getattr(Struct, f[0])

[issue21815] imaplib truncates some untagged responses

[R. David Murray]

R. David Murray added the comment:

Postel's Law says: be conservative in what you do, be liberal in what you 
accept from others.  So the client should not violate the RFC when sending data 
to the server.  The server, on the other hand, by that law could accept "dirty" 
data if it can do something reasonable with it...except that in general the 
IMAP RFC in particular says "don't do that".  IMAP servers are supposed to be 
IMAP RFC sticklers, even when accepting input.  So gmail is broken for some 
definition of broken, and so is imaplib.

Since the code has been this way for a long time, and gmail does in fact accept 
it, I think a doc warning about []s violating the RFC should be sufficient; a 
warning would probably just be annoying to little real benefit.

[issue21927] BOM appears in stdin when using Powershell

[eryksun]

eryksun added the comment:

> PS C:\Users\jaraco> echo £ | py -3 -c "import sys;

> Curiously, it appears as if powershell is actually receiving

PowerShell calls ReadConsoleW to read the console input buffer, i.e. it reads 
"£" as a wide character from the command line. The default encoding when 
writing to the pipe should be ASCII [*]. If that's the case it explains the 
question mark that Python reads from stdin. It's the default replacement 
character (WC_DEFAULTCHAR) used by WideCharToMultiByte. 

[*] 
http://blogs.msdn.com/b/powershell/archive/2006/12/11/outputencoding-to-the-rescue.aspx

You can change PowerShell's output encoding to match the console:

$OutputEncoding = [Console]::OutputEncoding

If the console codepage is 65001, the above is equivalent to setting 

$OutputEncoding = [System.Text.Encoding]::UTF8

http://msdn.microsoft.com/en-us/library/system.text.encoding.utf8

As Victor mentioned, this setting always writes a BOM, and under codepage 65001 
it actually writes 2 BOMs (at least in PowerShell 2). Victor also mentioned 
that you can avoid the BOM by passing $False to the constructor:

$OutputEncoding = New-Object System.Text.UTF8Encoding($False)

http://msdn.microsoft.com/en-us/library/system.text.utf8encoding

There's still a BOM under codepage 65001, but maybe that's fixed in PowerShell 
3. 

I avoid setting the console to codepage 65001 anyway. ReadFile/WriteFile 
incorrectly return the number of characters read/written instead of the number 
of bytes because the call is actually handled by ReadConsoleA/WriteConsoleA. 
Maybe that's finally fixed in Windows 8.

[issue21815] imaplib truncates some untagged responses

>>> first_id = msg_ids.split()[0]
>>> mail.store(first_id, "+FLAGS", "[test]")
('OK', [b'1 (FLAGS (\\Seen Answered [test] NotJunk $NotJunk [Brackets]
[testing2]))'])

However, I would think it would be the server's job to uphold this rule,
not the library. The server should return with a BAD response, but right
now, Gmail allows you to do this.

Should we throw a warning in the "store" method? Otherwise, I can update
the documenation in the "store" method stating that having '[]' is allowed
but violates the RFC protocol.

[issue21988] Decrease iterating overhead in timeit

[Antoine Pitrou]

Antoine Pitrou added the comment:

I think it is overkill. Apart from rather silly microbenchmarks, there 
isn't much point in adding the loop unrolling facility. In real world, 
even cheap operations such as "x = x + 1" will be surrounded by less 
cheap operations, so if an improvement cannot yield tangible benefits 
inside a simple for loop, then it doesn't deserve to be committed.

[issue21247] test_asyncio: test_subprocess_send_signal hangs on Fedora builders

[STINNER Victor]

STINNER Victor added the comment:

Here is a patch implementing a basic synchronization between the parent and the 
child processing, to wait until the child is sleeping.

Can you please try this patch?

If it doesn't work, we might add a small sleep of 500 ms after the readline().
