[issue25572] _ssl doesn't build on OSX 10.11

[Caleb Hattingh]

Caleb Hattingh added the comment:

I struggled with this issue, and eventually found the recommendations about 
linking with homebrew's OpenSSL on StackOverflow or similar, and then only 
later found this issue here (and with it the link to the devguide); but the 
*first* places I looked were the README in the source root, and then the README 
in the Mac/ directory. That may however just be ignorance on my part of where I 
should have been looking. Yet another reminder that I need to become much more 
familiar with the devguide.

The README only mentions the devguide in the context of contributing, but not 
that it will contain further information required for building. Under "Build 
Instructions", the README says:

***

Build Instructions
--

On Unix, Linux, BSD, OSX, and Cygwin:

./configure
make
make test
sudo make install

This will install Python as python3.

You can pass many options to the configure script; run "./configure --help" to 
find out more.  On OSX and Cygwin, the executable is called python.exe;
elsewhere it's just python.

On Mac OS X, if you have configured Python with --enable-framework, you should 
use "make frameworkinstall" to do the installation.  Note that this installs 
the Python executable in a place that is not normally on your PATH, you may 
want to set up a symlink in /usr/local/bin.

***

It might be helpful to add to the README (in the "Build Instructions" section): 

"The devguide may include further information about specific build dependencies 
for your platform here: 
https://docs.python.org/devguide/setup.html#build-dependencies";

[issue27304] Create "Source Code" links in module sections, where relevant

[Terry J. Reedy]

Terry J. Reedy added the comment:

Three of the links are to one- or two- line modules that import the C 
implementation.  I considered dropping them, but decided that the only way to 
know that they are not worth looking at is to let someone take a look.  A 
counter argument is that we don't have links to CPython C implementations, and 
we could pretend that the Python wrappers are not there. Another core developer 
who feels strongly enough can remove the three.

Thanks for the nice patch.  I hope you do some more.

[issue27370] Inconsistency in docs for list.extend

[Martin Panter]

Martin Panter added the comment:

The t vs x mixup was introduced by my sloppy backport in Issue 16701. The other 
problem here is x is generally defined as any arbitrary object, but redefined 
as an iterable in the footnote. I think we should use t instead, as in the 
other two slice assignment operations and in Python 3. My commit should have 
fixed both these problems.

[issue22228] Adapt bash readline operate-and-get-next function

It looks like ctypes uses ffi_closure_alloc() to allocate an executable 
function on demand. So it should be possible for readline to also call libffi 
and do this, but certainly not trivial.

>>> from ctypes import *
>>> @CFUNCTYPE(c_int, c_int, c_int)
... def operate_and_get_next(count, char):
... print("Boo!", count, char)
... return 0
... 
>>> libreadline = CDLL("libreadline.so.6")
>>> libreadline.rl_add_defun("operate-and-get-next", operate_and_get_next, 
>>> ord("O") & 0x1F)
0

[issue25588] Run test suite from IDLE idlelib.run subprocess

[Terry J. Reedy]

Terry J. Reedy added the comment:

The premise of the issue is this: if IDLE is started with 'pythonx', then 
running 'filex' from a IDLE editor is equivalent to running "python x -i filex" 
at a command line.  For instance, loading test.__main__ into an editor and 
running should give the same result as 
f:/python/dev> 36\pcbuild\win32\python_d.exe -i 36\Lib\test.__main__

However, 
Traceback (most recent call last):
  File "F:\Python\dev\36\Lib\test\__main__.py", line 2, in 
main()

The pseudofile socket wrappers are not real files with a fileno.  I should take 
a better look as sys.stdout and _stdout (and stderr) when connected to a 
console,

[issue27369] [PATCH] Tests break with --with-system-expat and Expat 2.2.0

[Martin Panter]

Martin Panter added the comment:

Thanks for the patches. This test was added in r74435, presumably to test for a 
crash. IMO it would be sufficient to test for the first part of the error 
message, without checking the column number. The test could also use 
assertRaisesRegex().

Should this actually be applied to all security versions, or just 3.5+ and 2.7? 
I guess can see the benefit of fixing 3.2+, and I remember doing this once 
before when the test suite fell over and it was not Python’s fault.

[issue22115] Add new methods to trace Tkinter variables

[Terry J. Reedy]

Terry J. Reedy added the comment:

I gather that 'add', 'delete', and 'info' replace 'variable', 'vdelete', and 
'vinfo'.  Also see review.  Deprecation period should be fairly long.  Of 
course, a currently hypothetical tcl/tk 9.0 with old stuff gone would make it 
immediate for users of 9.0.

Applies cleanly and tests pass, but do not hardly interact with the patch.  
More importantly, IDLE starts fresh, option dialog comes up and appears to 
work.  So old functions continue to work.

The real test from IDLE would be to recode configdialog to use the new 
functions and then test.  I am thinking about how to test configdialog enough 
that I am willing to refactor it for real.

[issue27362] json.dumps to check for obj.__json__ before raising TypeError

[R. David Murray]

R. David Murray added the comment:

Pretty much any project that makes non-trivial use of json ends up implementing 
a jsonification protocol, usually by creating either a __json__ method or (more 
commonly, I think) a to_json method.

But, yeah, this is python-ideas material and would get into the stdlib only as 
an officially blessed protocol, in which case using __json__ would make sense.  
So I'm going to close the issue pending a consensus on python-ideas.  If it 
gets accepted the issue can be reopened.

[issue27196] Eliminate 'ThemeChanged' warning when running IDLE tests

[Terry J. Reedy]

Terry J. Reedy added the comment:

The only thing I still see is a pair of ThemeChanged warnings from 2.7.  Using 
binary search, I identified test_editmenu as the culprit.  This in spite of all 
the cleanup I can think of

@classmethod
def tearDownClass(cls):
del cls.text, cls.entry, cls.spin
cls.root.clipboard_clear()
cls.root.update_idletasks()
cls.root.update()
cls.root.destroy()
del cls.root

When I tried to determine which test method(s) gave the warning, as disable all 
to make sure the warnings vanished, which then did.  But after re-enabling, the 
warnings did not come back -- until they did after a few more runs.  I suspect 
that the only permanent solution will be Serhiy's patch to have .destroy cancel 
pending callbacks.

[issue27372] Test_idle should stop changing locale

[Terry J. Reedy]

New submission from Terry J. Reedy:

test.test_idle has long resulted in warnings about the locale being changed.  
In 3.6, this warning causes test_idle to be tagged a failure. Though this does 
not (yet) turn the overall run of a buildbot from green to red, it is annoying 
to have success reported as a failure.

The culprit is in iomenu: locale.setlocale(locale.LC_CTYPE, "") Commenting it 
out removed the warning and tests pass. But I don't know the real effect, if it 
would work for tests on all systems, and the consequence when running IDLE 
normally.

The problem cannot be monkey-patched away since the damage is done on import.  
Instead I added 'testing = False' to idlelib.__init__, made test_idle change it 
to True, and replace the locale-encoding code with "encoding = 'utf-8'" when 
testing is True.

Serhiy, I *think* this is ready.  However, another eagle-eye review would be 
welcome.  Tests also pass with 'ascii'.  Would that be better?

---
Side note: the locale and encoding code could use a review from someone who 
knows more that me.  For instance, suppressing ImportError here:

try:
import locale
locale.setlocale(locale.LC_CTYPE, "")
except (ImportError, locale.Error):
pass

guarantees a NameError a few lines further.  There is another chunk labelled 
deprecated, and more might be obsolete in 3.x.  But this is another issue.

[issue27371] Runaway memory consumption using update()

[Jeremy Blow]

New submission from Jeremy Blow:

Hi folks, 

While going about running tkinter's update() call within a coroutine/asyncio 
event loop in lieu of using mainloop(), I came across odd memory behavior on 
MacOS where the cpython process gradually increases memory consumption. 
Suspicious that there may be some unfavorable interaction between asyncio's use 
of KqueueSelector and the lower level tk calls, I stripped things down to a 
simple implementation and found the behavior exhibits itself without asyncio 
involved at all. 

```
import tkinter as tk


def start(root):

while True:
root.update()


# tk update loop: mem consumption increases
start(tk.Tk())

# tk mainloop: mem consumption stable
# tk.Tk().mainloop()
```

# Using tk mainloop, ~1 minute

That's 31,756,288 versus 545,976,320 after ~1 minute. If I let the update loop 
continue, it eventually consumes many gigabytes of memory. 

Obviously something is very wrong here. To further the fun, I've tested this 
across three Macs, and only two exhibit the behavior. This may or may not be 
interesting to those who are already aware of Tk / Cocoa event loop interaction 
issues.

+---+++--+
| MacOS Version | Python Version | Tcl/Tk Version | Exhibits |
+---+++--+
| 10.11.3/15D21 | 3.5.1  | 8.5/8.5| Yes  |
| 10.9.4/13E28  | 3.5.1  | 8.5/8.5| No   |
| 10.11.2/15C50 | 3.5.1  | 8.5/8.5| Yes  |
+---+++--+

Could someone illuminate me as to as whether I'm facing a PEBKAC, update() is 
lacking some housekeeping that exists in the mainloop routine, a new/known bug, 
or other? Further troubleshooting steps I can take are appreciated, I'm happy 
to try to isolate it further. 

My use case is a tkinter app written solely w/ coroutines thus the event loop 
selection is constrained.

Env details below.. Cheers.

[issue27172] Add skip_bound_arg argument to inspect.Signature.from_callable()

[Nick Coghlan]

Nick Coghlan added the comment:

OK, so maybe the right answer here is to officially undeprecate 
inspect.getfullargspec(), as we definitely *don't* want people feeling obliged 
to write their own version of that, and potentially introducing inconsistencies 
between different tools.

Then the deprecation warning on inspect.getargspec() can be updated to point 
people towards "inspect.signature() or inspect.getfullargspec()", while the 
docs for getfullargspec() itself can be updated to say it isn't recommended for 
use in new code, rather than that it's deprecated.

You speak confidently, for a guy who hasn't seen any sort of schedule from the 
3.5 RM.  :-O

After 3.6 comes out, I expect 3.5 to get one more "bug fix" release.  And 
*then* it will transition to "security fixes only" mode.  Six months is the 
absolute minimum, and I'd expect it to be longer than that.

[issue27172] Add skip_bound_arg argument to inspect.Signature.from_callable()

[Ryan Petrello]

Ryan Petrello added the comment:

Nick,

My main reasoning for not using it is that it's marked as deprecated in the 
docstring, and I want to avoid relying on it if disappears in the future :)

Warnings or not, the shim that I wrote doesn't use any deprecated code, so 
that's why I took that approach.

[issue27172] Add skip_bound_arg argument to inspect.Signature.from_callable()

[Nick Coghlan]

Nick Coghlan added the comment:

Are you able to use inspect.getfullargspec() on Python 3 rather than 
inspect.getargspec()?

While both are technically deprecated, only inspect.getargspec() actually emits 
a deprecation warning - inspect.getfullargspec() still works without complaint 
and is in no danger of being removed.

[issue27370] Inconsistency in docs for list.extend

[Andrew Cameron]

New submission from Andrew Cameron:

The documentation for Mutable Sequence Types states that, for operation:
s.extend(x) or s += t

the expected result is:
for the most part the same as s[len(s):len(s)] = x

Note that if you perform operation 's += t' the result is not the same as 
's[len(s):len(s)] = x' unless 't == x'.

This does not occur with the Python 3 docs, which uses exclusively 't' (not 
'x'). However for people reading the Python 2 docs the variable mix-up could 
cause confusion.

[issue27365] Allow non-ascii chars in IDLE NEWS.txt (for contributor names)

[Terry J. Reedy]

Terry J. Reedy added the comment:

No, it ends with the last 3.5 maintenance release in about 6 months.  When I 
did it right, as in #27245, which was otherwise a clean single file merge, 
there was no problem and it took at most an extra 30 seconds.  I know what I 
did wrong this time, starting with not writing down the steps needed, and in 
which order, for a much more complicated merge.

Probably not in 2.7.  It may be broken, but what if someone is depending on it? 
 (Unlikely, but the chance of it outweighs the benefit of changing it in a 
mainteance release.)

Does the same problem exist in 3.6?  That's probably the only version where we 
would change it.

[issue27172] Add skip_bound_arg argument to inspect.Signature.from_callable()

[Ryan Petrello]

Ryan Petrello added the comment:

Nick,

My use case is an issue of backwards compatibility and multiple Python version 
support for a library that makes prolific use of the legacy argspec (args, 
varargs, varkw, defaults) namedtuple, *including* the bound self argument 
behavior.  argspec and signature are quite different, and supporting a 
Py26-Py36 codebase that handles both simultaneously seemed like quite a burden, 
so I opted to write a compatibility shim that returned an Argspec-like object 
for all versions of Python;  this seemed the simplest approach to bridge the 
gap in a codebase that supports Python 2.6 through 3.6, and it's the approach 
that I've seen other major libraries (like Django) take:

https://github.com/pecan/pecan/pull/61

I'm using a similar approach to Python 3.5's getfullargspec() implementation:

https://github.com/python/cpython/blob/3.5/Lib/inspect.py#L1069

...but I don't have a long-term public API for doing it (so I have to rely on 
the private inspect._signature_from_callable call, which seems icky).

I suspect it is a problem with textView/textview, so I will temporarily disable

Problem:
os.mkdir is not working for multiple level of directory creation in windows 
environment.

Explanation:
Suppose there is a directory whose path is "D:\Output"

Now to create 2 levels of directory in side the path "D:\Output", when 
os.mkdir("D:\Output\Dir1\Dir2") is used, python 2.7 throws errors as below:
Traceback (most recent call last):
  File "", line 1, in 
WindowsError: [Error 3] The system cannot find the path specified: 
'D:\\Output\\Dir1\\Dir2'

Please update python to create multiple level of directory.

[issue26859] unittest fails with "Start directory is not importable" when trying to run sourceless tests

[Xavier de Gaye]

Xavier de Gaye added the comment:

> the list_dir() nested function is never called
Verifying that load_tests is called is the purpose of this test. In this case 
should_recurse is false in _find_tests() and os.listdir() is not invoked by 
this method.

This new patch does not use vfs and list_dir and uses subtests to also check 
that TestLoader.discover() does consider that a path refers to a package 
directory when it contains an '__init__.pyc' file and no '__init__.py' file, 
and vice-versa.

I should mention that I have separate 3.5 and 3.6 patches because I know that

[issue27365] Allow non-ascii chars in IDLE NEWS.txt (for contributor names)

[Larry Hastings]

Larry Hastings added the comment:

If the diff is literally changing two lines, I'll accept it.  Guido relaxed the 
rules for IDLE changes.  If it breaks something it's on *your* head ;-)

Please just check it in normally.  Either I'm going to use hg to cherry-pick 
the changes for 3.5.2 final, or I'm going to have to apply patches manually 
anyway.  Either way an hg checkin is fine.

Please check in this minimal change *as a separate checkin* from the larger 
changes, if you're committing the other changes any time soon.

[issue27366] PEP487: Simpler customization of class creation

[Martin Teichmann]

New submission from Martin Teichmann:

This is the implementation of PEP 487.

It adds a metaclass to types that calls a method on a class
once it is subclassed. This way one can customize the creation
of classes without the need to write an own metaclass.

As a second functionality, it calls a method on each descriptor
in a class, such that descriptors know their name.

[issue22228] Adapt bash readline operate-and-get-next function

[Lele Gaifax]

Lele Gaifax added the comment:

I addressed Martin's comments (thank you!) in
https://github.com/lelit/cpython/commits/issue8_2, removing pointless
usage of a macro and avoiding usage of module's state to store the "next line
index", keeping it in a plain static variable.

Let me know how it looks now.

Yes, it confused me too. Also, there is at least one spot in setup_readline()
that seems wrong to me, because it does not consider if it's effectively using
libedit:

#ifndef __APPLE__
if (!isatty(STDOUT_FILENO)) {
/* Issue #19884: stdout is not a terminal. Disable meta modifier
   keys to not write the ANSI sequence "\033[1034h" into stdout. On
   terminals supporting 8 bit characters like TERM=xterm-256color
   (which is now the default Fedora since Fedora 18), the meta key 
is
   used to enable support of 8 bit characters (ANSI sequence
   "\033[1034h").

   With libedit, this call makes readline() crash. */
rl_variable_bind ("enable-meta-key", "off");
}
#endif

I will try to find some spare time to spend on this, but unfortunately I can
not promise I'll be able to do that in the near future, sorry.

Yeah, I know (I've been here nearly from the beginning ;-).
