I believe I read somewhere (SO?) that root.withdraw sometimes affects the

[issue27364] Deprecate invalid escape sequences in str/bytes

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Yes, this was the intention. One of often errors is using "\n" in non-raw 
docstrings. This change doesn't prevent this error, but increases chances of 
catching it when there are other backslashes in the docstring.

[issue27364] Deprecate invalid escape sequences in str/bytes

[Jason R. Coombs]

Jason R. Coombs added the comment:

One consequence of this change is that now any string that has a backslash 
needs to be escaped or raw, leading to changes like this on 
(https://github.com/cherrypy/cherrypy/pull/1610/commits/1d8c03ea8c5fe90f29bbea267300b97c78391c24#diff-be33a4f55d59dfc70fc6452482f3a7a4)
 where the diagram in the docstring is the culprit. An escaped backslash is not 
viable in this case, so a raw string is required.

This particular example strikes me as counter-intuitive, though maybe I just 
need to adjust my intuition.

Was the intention for a docstring like above to use raw strings?

Again, that is not HTTPS. Don't confuse port number with protocol!

As Chris says, Google Groups is essentially a web forum that happens to
mirror Usenet content.  It's not a news service itself (no NNTP), not an
NNTP server.  So if GG is causing users problems, the solution is to
ditch it and use something better, like a standalone NNTP client and a
real Usenet server.  Or python-list via email.

I wish there was a decent (free) API that everyone used for web forums
that would let me use a decent, threaded news reader to browse forums.
I once wrote a forum scraper using BeautifulSoup that downloaded posts,
along with graphics and made them into MIME messages served over NNTP
(using Twisted) to my NNTP client.  So much information is lost in web
forums (there's no threading in web forums) that it didn't work out that
well.

[issue30803] Truth value of sets not properly documented

[Terry J. Reedy]

Terry J. Reedy added the comment:

Responding here to Peter's PR comment.  Peter opened this issue with the claim 
that the doc failed a specific test case-- document the truth value of set().  
Since mappings are (or can be viewed as) a specialized type of set, I always 
considered that the empty mapping line implicitly covered sets.  But I 
acknowledge that this is not clear for everyone.  The simplest fix to make the 
test pass would be: "any unordered collection, for example, set(), {}".  This 
should also cover frozenset and a possible frozendict.

Raymond noted that 'user-defined' in the last bullet point is wrong (it implies 
that built-in functions are different) and should be deleted.  He then combined 
the corrected rule for false with the default rule in the next sentence to 
produce a succinct statement of the actual rule.  (In CPython, 'default' is 
literally true. Class 'object' has neither __bool__ nor __len__; ditto for all 
subclasses that do not add one.)

With a minor change, I like this statement and agree that it should be moved 
above the examples.  But I think the bullet points should be reduced to just 3, 
rewritten, and single spaced, but not smashed into running text.  I suggest 
replacing everything between the first sentence (ending with 'below.') and the 
last two (beginning with 'Operations') with:

"By default, an object is considered true unless its class defines either a 
__bool__ method that returns False or __len__ method that returns zero, when 
called with the object.  Here are most of the built-in objects considered false.

* constants defined to be false: None and False.
* numeric 0 of any type: 0, 0.0, Decimal(0), Fractions(0, 1)
* empty sequences and collections: '', (), [], {}, set(), range(0)
"

Before writing the above, I checked that an instance attribute __bool__ = 
lambda: False is not consulted by bool().

[issue30893] Expose importlib._bootstrap._ModuleLockManager in importlib.machinery

[Nick Coghlan]

Nick Coghlan added the comment:

Based on https://github.com/python/cpython/pull/2646/files#r126574323, I'm 
actually thinking along different lines: I'm starting to think we should move 
the current sys.modules to sys._modules, and make sys.modules a synchronised 
wrapper that does the following for all get/set/delete operations:

  # Acquires the global import lock
  # Acquires the relevant module lock
  # Releases the global import lock
  # Mutates sys._modules
  # Releases the module lock

That said, I'm not sure that would be sufficient to give the desired level of 
atomicity, so exposing ModuleLockManager may actually be a better approach.

[issue30894] Python 3.6.1 String Literal Error Not Going to sys.stderr

[Steven D'Aprano]

Steven D'Aprano added the comment:

Before Python runs your code, it compiles it to byte-code. A SyntaxError means 
that the code cannot be compiled, and so it does not run.

So the SyntaxError is raised *before* any of the code runs, and standard error 
is not re-directed. This is expected behaviour, not a bug. You cannot catch 
compile-time errors at run-time.

[issue30896] BytesWarning in re module when compiling certain bytes patterns

[Jelle Zijlstra]

New submission from Jelle Zijlstra:

This code in sre_parse (line 738 and down):

warnings.warn(
'Flags not at the start of the expression %s%s' 
% (
source.string[:20],  # truncate long regexes
' (truncated)' if len(source.string) > 20 
else '',
),
DeprecationWarning, stacklevel=7
)


triggers a BytesWarning if you do `_line_re = re.compile(br'^(.*?)$(?m)')`.

The fix should be simple; I can try to get a PR in over the next few days.

ANN: A new version (0.4.1) of python-gnupg has been released.

[Vinay Sajip via Python-list]

A new version of the Python module which wraps GnuPG has been released.

What Changed?
=
This is an enhancement and bug-fix release, and all users are encouraged to 
upgrade.
See the project website [1] for more information.

Brief summary:

* Updated message handling logic to no longer raise exceptions when a message 
isn't
  recognised. Thanks to Daniel Kahn Gillmor for the patch.
* Always use always use --fixed-list-mode, --batch and --with-colons. Thanks to 
Daniel
  Kahn Gillmor for the patch.
* Improved scan_keys() handling on GnuPG >= 2.1. Thanks to Daniel Kahn Gillmor 
for the
  patch.
* Improved test behaviour with GnuPG >= 2.1. Failures when deleting test 
directory trees
  are now ignored. Thanks to Daniel Kahn Gillmor for the patch.
* Added close_file keyword argument to verify_file to allow the file closing to 
be made
  optional. Current behaviour is maintained - close_file=False can be passed to 
skip
  closing the file being verified.
* Added the extra_args keyword parameter to allow custom arguments to be passed 
to the
  gpg executable.
* Instances of the GPG class now have an additional on_data attribute, which 
defaults to
  None. It can be set to a callable which will be called with a single argument 
- a binary
  chunk of data received from the gpg executable. The callable can do whatever 
it likes
  with the chunks passed to it - e.g. write them to a separate stream. The 
callable should
  not raise any exceptions (unless it wants the current operation to fail).

This release [2] has been signed with my code signing key:

Vinay Sajip (CODE SIGNING KEY) 
Fingerprint: CA74 9061 914E AC13 8E66 EADB 9147 B477 339A 9B86

What Does It Do?

The gnupg module allows Python programs to make use of the
functionality provided by the Gnu Privacy Guard (abbreviated GPG or
GnuPG). Using this module, Python programs can encrypt and decrypt
data, digitally sign documents and verify digital signatures, manage
(generate, list and delete) encryption keys, using proven Public Key
Infrastructure (PKI) encryption technology based on OpenPGP.

This module is expected to be used with Python versions >= 2.4, as it
makes use of the subprocess module which appeared in that version of
Python. This module is a newer version derived from earlier work by
Andrew Kuchling, Richard Jones and Steve Traugott.

A test suite using unittest is included with the source distribution.

Simple usage:

>>> import gnupg
>>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory')
>>> gpg.list_keys()

[{
...
'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2',
'keyid': '197D5DAC68F1AAB2',
'length': '1024',
'type': 'pub',
'uids': ['', 'Gary Gross (A test user) ']},
{
...
'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A',
'keyid': '0C5FEFA7A921FC4A',
'length': '1024',
...
'uids': ['', 'Danny Davis (A test user) ']}]
>>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A'])
>>> str(encrypted)

'-BEGIN PGP MESSAGE-\nVersion: GnuPG v1.4.9 (GNU/Linux)\n
\nhQIOA/6NHMDTXUwcEAf
.
-END PGP MESSAGE-\n'
>>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret')
>>> str(decrypted)

'Hello, world!'
>>> signed = gpg.sign("Goodbye, world!", passphrase='secret')
>>> verified = gpg.verify(str(signed))
>>> print "Verified" if verified else "Not verified"

'Verified'

As always, your feedback is most welcome (especially bug reports [3],
patches and suggestions for improvement, or any other points via the
mailing list/discussion group [4]).

Please refer to the documentation [5] for more information.

Enjoy!

[issue24776] IDLE: Improve config dialog font change user interface

[Terry J. Reedy]

Terry J. Reedy added the comment:

Make this the master issue for improving the font tab user interface by 
improving components and rearranging them.  With basic tests done, I am moving 
this up in priority.

Related issues currently open.
#30870 (dependency) made Up/Down change font selection; unit test needed.
#27755 replaces IDLE's custom DynOptionMenu with ttk.Combobox.  Comboboxes 
allow key entry of a value and the arrow toggles. See msg298091 for comparison 
and evaluation for font page.
#13802 (dependency) is about the improving the sample display.
#17642 is about font resizing by hot key and wheel in editor.
#20917 is about the font change notification system.

Additional changes for this issue or new related issues.

* Selecting a font by name (as well as a font size by number) can be done with 
an entry box with a validator linked to the listbox.  If a ttk Combobox can be 
locked open, I would try that.  See #27755.  For a demo of another alternative, 
run the tk fontchooser.

import tkinter
root = tkinter.Tk()
root.tk.call('tk', 'fontchooser', 'show')

For IDLE, I like some parts, not others.  I view it as an alternate mockup for 
ideas to build on.

* Mark's mockup removes "Base Editor Font".  If an editor window can have its 
font individually resized, then the settings on the font page define just that. 
 'Font Size' would then have to be 'Starting [or Default] Font Size'. 

* Font size a slider?  I am not convinced.  It would have to be vertical to go 
up to 40.  (I added larger sizes by request for classroom projector use.)  On 
the other hand, it would allow any size in the given range.  A spinbox that 
could be spun by mousewheel would also and stay compact.  Or use a ttk Combobox.

* See #13802 for discussion of sample display.

* Indent.  I don't understand "cries out to be moved (usually when people are 
intending to increase their font size)."  But I think it take too much space 
and should be shrunk to a spin box or drop box.  Reduced to a single line, I am 
thinking of moving it to the General tab, or perhaps a new Editor tab.  It does 
not particularly belong with font selection.

* Factor the Font page, with associated Variables and their tracers, other 
attributes, and methods, into a FontPage class.

[issue27755] Retire DynOptionMenu with a ttk Combobox

[Terry J. Reedy]

Terry J. Reedy added the comment:

I did more experiments with DOM (DynamicOptionMenu) and Combobox (CB).  This 
was partly to evaluate CB as replacement for DOM for font size; partly to 
consider CB for the font list.   At least by default, both start closed.  Font 
list should start open. CB has an Entry area, DOM does not.  They get focus by 
clicking.  Both open with Down or click on Down button.  DOM also opens on Up, 
not essential. CB adds scrollbar if needed.  DOM?  Needed for font list.  Up 
and Down move the selection highlight but do not select.  Selection by click 
and  close the box and generate <>  This is unlike 
Listbox where moving highlight generates <>.  #30870 fixed code 
so that Up and Down, in addition to click, caused sample change.  I want to 
keep this for font choice and add it for size choice.  For CB, click on Down 
button closes without changing selection.  For DOM, it does not, a deficiency.

Compiling Python 3.6.1 on macOS 10.12.5

[Nigel Palmer]

Hi

I am trying to compile Python 3.6.1  on macOS 10.12.5 with xcode 8.8.3 using 
the instructions at 
https://docs.python.org/devguide/setup.html#build-dependencies but I am getting 
the error

./python.exe -E -S -m sysconfig --generate-posix-vars ;\
if test $? -ne 0 ; then \
echo "generate-posix-vars failed" ; \
rm -f ./pybuilddir.txt ; \
exit 1 ; \
fi
/bin/sh: line 1: 96973 Killed: 9   ./python.exe -E -S -m sysconfig 
--generate-posix-vars
generate-posix-vars failed
make: *** [pybuilddir.txt] Error 1

When I manually run that command using dbll I get:

lldb ./python.exe -- -E -S -m sysconfig --generate-posix-vars
(lldb) target create "./python.exe"
Current executable set to './python.exe' (x86_64).
(lldb) settings set -- target.run-args  "-E" "-S" "-m" "sysconfig" 
"--generate-posix-vars"
(lldb) r
Process 96978 launched: './python.exe' (x86_64)
Could not find platform dependent libraries 
Consider setting $PYTHONHOME to [:]
Process 96978 exited with status = 0 (0x)
(lldb)


The commands I ran to configure and build python are:
brew install openssl xz
CPPFLAGS="-I$(brew --prefix openssl)/include" LDFLAGS="-L$(brew --prefix 
openssl)/lib" ./configure --prefix=`pwd`/../build
make

Any ideas on what I am doing wrong?

Many Thanks
Nigel

[issue30894] Python 3.6.1 String Literal Error Not Going to sys.stderr

[George Gillan]

New submission from George Gillan:

Python 3.6.1 String Literal Error Not Going to sys.stderr

Using Windows 7 and Python 3.6.1. Attempting to redirect sys.stderr to a file. 
The application will be deployed via .pyw file instead of .py so the GUI 
application runs without a console window.

Is this fixable or 'as-is' due to the nature of the way the interpreter scans 
the code?

The following code worked as intended.

#!/usr/bin/env python3.6 
errfile = 'test_err.txt'

import sys
errorlog = open(errfile, 'w')
sys.stderr = errorlog

1/0

The code above produced a file called test_err.txt with the following contents:

Traceback (most recent call last):
  File "C:\Users\George\Coding\Python\test\mintest.py", line 8, in 
1/0
ZeroDivisionError: division by zero


The following code did not work as intended.

#!/usr/bin/env python3.6 
errfile = 'test_err.txt'

import sys
errorlog = open(errfile, 'w')
sys.stderr = errorlog

print("test)

The code above did not create the file test_err.txt with the error going to the 
console window instead.


Copy-paste from the Windows console.

The successful test (first) showed nothing in the console window; the error was 
logged to the file as noted above. The unsuccessful test (second) did not 
create the file, instead the error was sent to the console.

C:\Users\George\Coding\Python\test>mintest

C:\Users\George\Coding\Python\test>mintest
  File "C:\Users\George\Coding\Python\test\mintest.py", line 8
print("test)
   ^
SyntaxError: EOL while scanning string literal

C:\Users\George\Coding\Python\test>

PS: This is my first bug/issue submission here. Please coach me as needed if I 
messed it up.

RFC 4642 (updated by RFC 8143) describes the use of TLS with NNTP. It
enhances the connection between NNTP client and server, primarily with
encryption but optionally with other benefits.

Of course it does nothing to improve the content of Usenet.

[issue20917] Idle: Enhance font change notification system

[Terry J. Reedy]

Terry J. Reedy added the comment:

I believe I saw somewhere that the 'somehow' in the opening post is looping 
through the windows listed under the Window tab.

This issue was inspired by #17642, which allows hotkeys (^-, ^+) and wheel to 
change font size in editor window.  If the size change only applies to the 
current window, then only the CodeContext for that window should be notified.  
If CodeContext becomes a feature rather than extension, #27099, then code 
editor windows could know they have a code context and notify it when they get 
notified.  That will not help external extensions.

What's the meaning of "https news service" then? If it's netnews, it's
NNTP, not HTTP. If it just happens to be a web app that carries
information from a newsgroup, then that's not a news service, it's a
web forum, and there's no such thing as a generic web forum API.

Traditionally NNTP over SSL was done on port 563.  Some feeds now also
provide it on 443 to get around client-side firewall hassles.

I don't think that rule would block too many reasonable posts. On the
other hand, I also block everything from Google Groups, and, as of
recently, everything from netfront.net, so I don't actually worry too
much about false positives in this group, given it contains so much
trash.

And wrong.

Two equivalent integer objects _might_ be the same object, but that's
not guaranteed.  It's an _implementation_detail_ of CPython that small
integers are cached:

  >>> x =  0
  >>> x is 0
  True

But larger integers aren't:

  >>> a =  123412341234
  >>> a is 123412341234
  False

The first example could have returned False and been correct.

[issue30891] Sometimes, test_concurrency() of test_import fails with AttributeError: module 'package' has no attribute 'submodule' on AMD64 Windows8.1 Refleaks 3.6

[Nick Coghlan]

Nick Coghlan added the comment:

I'm about to head to bed so I'll get back to this discussion tomorrow, but in 
the meantime: Victor, maybe it would make sense to reformulate your reproducer 
as a monkeypatch for _find_and_load_unlocked() that injects the 10 ms sleep 
from the test case if it finds _frozen_importlib in sys.modules?

That is, temporarily replacing it with something like:

orig_find_and_load_unlocked = _frozen_importlib._find_and_load_unlocked
def _slow_find_and_load_unlocked(name, import_):
time.sleep(0.010)
return orig_find_and_load_unlocked(name, import_)

That way, we'd hopefully be able to reproduce the failure independently of the 
slower buildbot.

That is probably ok, but I was worried some legit posts would get caught
