I picked a bluish green that works on both white and black on Windows.  Test is 
you can and wish.

Of course, I cannot set the background on my Mac, so I will test on Windows and 
let you verify on dark theme mac

[issue44254] Change turtledemo button colors

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I presume you tested pr_26448.  If default colors do not work, that is on 
tcl/tk.  I suspect 8.6.11 is not prepared for dark theme.  The underlying bug 
is ignoring the tk/user setting and deferring to the system for background only.

In the meanwhile, I will try to set the forground to something at least 
readable on either background.  Is the dark theme background black as opposed 
to dark something?

[Ned Deily]

Ned Deily  added the comment:

I also just did a quick test of PR 25448. The current version seems to have 
swapped one problem for another: now button labels are legible when the Light 
mode appearance is in effect but the labels blend into the button background 
when in Dark mode, the opposite of the current behavior.

[Ned Deily]

Ned Deily  added the comment:

I did a quick check and it looks like the code may not be needed on the latest 
macOS and Tk versions; however, I did not go back and check it on older systems 
and, in any case, it doesn't cause seem to cause any harm and it still does 
what it is supposed to do: ensure that the turtledemo process is the frontmost, 
active one regardless of what the OS or Tk may do.

Terry J. Reedy  added the comment:

Ned, could you check the darwin osascript in turtledemo.__main__, lines 138-149 
is current (both needed and correct)?

subprocess.run(
[
'osascript',
'-e', 'tell application "System Events"',
'-e', 'set frontmost of the first process whose '
  'unix id is {} to true'.format(os.getpid()),
'-e', 'end tell',
],
stderr=subprocess.DEVNULL,
stdout=subprocess.DEVNULL,)

The one line could be an fstring now.

[issue44253] tkinter searches for tk.tcl in wrong directory

[Adam Stewart]

Adam Stewart  added the comment:

Thanks, that does help. Spack uses both `--with-tcltk-includes` and 
`--with-tcltk-libs`, and actually RPATHs the libraries in place. According to 
otool, that is all working fine:

$ otool -L 
/Users/Adam/spack/opt/spack/darwin-catalina-x86_64/apple-clang-12.0.0/python-3.8.10-fkj5vkn3tpottyv6yqoj5ucz2emstpvo/lib/python3.8/lib-dynload/_tkinter.cpython-38-darwin.so
/Users/Adam/spack/opt/spack/darwin-catalina-x86_64/apple-clang-12.0.0/python-3.8.10-fkj5vkn3tpottyv6yqoj5ucz2emstpvo/lib/python3.8/lib-dynload/_tkinter.cpython-38-darwin.so:

/Users/Adam/spack/opt/spack/darwin-catalina-x86_64/apple-clang-12.0.0/tcl-8.6.11-n7nea33urrk25rkoqpsc2tdcgai5u4z2/lib/libtcl8.6.dylib
 (compatibility version 8.6.0, current version 8.6.11)

/Users/Adam/spack/opt/spack/darwin-catalina-x86_64/apple-clang-12.0.0/tk-8.6.11-ydmhrbboheucxsuhrnyoxqaihgna5dfe/lib/libtk8.6.dylib
 (compatibility version 8.6.0, current version 8.6.11)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 1281.100.1)

So like you initially thought, the problem isn't that tkinter/_tkinter can't 
find tcl, it's that tcl can't find tk. I'll talk more with the tcl developers 
and see how tcl is trying to find tk. Thanks for all of your help!

[issue44254] Change turtledemo button colors

[Ned Deily]

Ned Deily  added the comment:

One quick comment: one shouldn't assume what colors are being used on current 
macOS systems and a current Tk, like on macOS 11 Big Sur and Tk 8.6.11.  The 
foreground and background colors can depend on what system appearance is 
selected by the user (System Preferences -> General -> Appearance: 
Light/Dark/Auto). Changing the system appearance to Dark causes the Turtle Demo 
buttons to have a darker background and so the white text labels are now quite 
visible.  I don't know what the best solution is but it shouldn't be based on 
the assumption that the colors are fixed.

[issue44252] test_ssl and test_httplib.HTTPSTest crash randomly with "Windows fatal exception: access violation" on Windows

[David Bolen]

David Bolen  added the comment:

Oddly, it turns out it's the "--junit-xml" parameter during buildbot tests that 
is making it reproducible there.

  Pass: python_d -m test.regrtest test_ssl
  Fail: python_d -m test.regrtest --junit-xml out.xml test_ssl

The latter consistently fails all of the time for me manually.

I also found what I think is the same commit Pablo just referenced (albeit the 
cherry pick version on the 3.10 branch) - 
ea47a8a71ad56ec349f02bf8c6a1d3bf04acabcc.  Reverting just that commit as part 
of the latest 3.10 source passes.

[issue44252] test_ssl and test_httplib.HTTPSTest crash randomly with "Windows fatal exception: access violation" on Windows

[STINNER Victor]

STINNER Victor  added the comment:

For me, there are different issues:

* PyType_FromSpec() must fail if a type is declared with Py_TPFLAGS_HAVE_GC but 
its tp_traverse function is NULL.
* _ssl.SSLError must implement the tp_traverse slot

Moreover, in debug mode, PyObject_GC_Track() calls the traverse function to 
ensure that it's safe to call it. PyObject_GC_Track() must crash of tp_traverse 
is NULL. If it didn't track, it means that the _ssl.SSLError instance was not 
tracked by the GC. Is that ok? Objects implementing the GC protocol should be 
tracked by the GC, no?

An exception is *likely* to be part of a reference cycle because it contains a 
traceback which contains frames which contains variables, and one variable can 
be the exception.

[issue44252] test_ssl and test_httplib.HTTPSTest crash randomly with "Windows fatal exception: access violation" on Windows

[STINNER Victor]

STINNER Victor  added the comment:

I remove Mark from the issue. I may open later a different issue for 
tb_frame.f_globals=None, but it's unrelated to this bug.

I can reproduce the issue with a small hack to make GC collections make likely:

diff --git a/Lib/site.py b/Lib/site.py
index 939893eb5e..4103792e84 100644
--- a/Lib/site.py
+++ b/Lib/site.py
@@ -672,3 +672,6 @@ def exists(path):
 
 if __name__ == '__main__':
 _script()
+
+import gc
+gc.set_threshold(5)


With this patch, it becomes trivial to reproduce the crash on Linux:

$ ./python -m test test_ssl -m test_ssl_cert_verify_error -v 
(...)
Fatal Python error: Segmentation fault

Current thread 0x7fd0f72a8640 (most recent call first):
  File "/home/vstinner/python/3.10/Lib/traceback.py", line 132 in 
format_exception
  File "/home/vstinner/python/3.10/Lib/test/test_ssl.py", line 262 in 
handle_error
  File "/home/vstinner/python/3.10/Lib/test/test_ssl.py", line 2401 in wrap_conn
(...)

So the problem is that _ssl.SSLError type traverse function is NULL.

[issue44253] tkinter searches for tk.tcl in wrong directory

[Ned Deily]

Ned Deily  added the comment:

tkinter does not find Tk; the linker at build time (ld) and usually the dynamic 
linker (dyld) at run time do all the work. Typically on macOS, the linkers 
prefer to dynamically link to libraries, deferring the decision to dyld at run 
time exactly which dynamic library will be linked to rather than statically 
linking in a library at build time. The expected shared library name (or path) 
is recorded at build time into the executables generated. The 
--with-tcltk-includes Python ./configure option is passed at build time to the 
C compiler chain to add the directories(s) for Tcl and Tk header files, if not 
otherwise found, and the --with-tcltk-libs option gives the locations of the 
libraries to add directories with Tcl and Tk libraries for ld to link against 
including generating the shared library file paths in the binaries produced.

In a standard Python build, tkinter has a Python component that calls a private 
C-language extension _module helper named _tkinter that does all the C-level 
calls to Tk and Tkinter. You can find the file name of the _tkinter extension 
module by importing it in the interpreter and looking at its __file__ 
attribute. With that you can use the Xcode / Command Line Tools "otool" utility 
to examine the binary to find the shared library names it is linked with and 
expecting to find at run time.

An example with a current python.org macOS Python:

$ /usr/local/bin/python3.9
Python 3.9.5 (v3.9.5:0a7dcbdb13, May  3 2021, 13:05:53)
[Clang 12.0.5 (clang-1205.0.22.9)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import _tkinter
>>> _tkinter.__file__
'/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/lib-dynload/_tkinter.cpython-39-darwin.so'
>>> ^D
$ otool -L 
'/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/lib-dynload/_tkinter.cpython-39-darwin.so'
/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/lib-dynload/_tkinter.cpython-39-darwin.so:
/Library/Frameworks/Python.framework/Versions/3.9/lib/libtcl8.6.dylib 
(compatibility version 8.6.0, current version 8.6.11)
/Library/Frameworks/Python.framework/Versions/3.9/lib/libtk8.6.dylib 
(compatibility version 8.6.0, current version 8.6.11)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 1292.100.5)

In this case, the libtcl and libtk shared libraries are included within the 
python.org distribution installed in /Library/Frameworks.

Another example with a MacPorts python built from source:

$ otool -L $(/opt/macports/bin/python3.9 -c "import 
_tkinter;print(_tkinter.__file__)")
/opt/macports/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/_tkinter.cpython-39-darwin.so:
/opt/macports/lib/libtcl8.6.dylib (compatibility version 8.6.0, current 
version 8.6.11)
/opt/macports/lib/libtk8.6.dylib (compatibility version 8.6.0, current 
version 8.6.11)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 1292.100.5)

In this case, the _tkinter module was linked with libtcl and libtk included in 
the MacPorts distribution.

Unlike many other platforms, the shared library names seen in macOS binaries 
are usually absolute path names although they can be relative paths.  It is 
possible to use environment variables to override the default search paths used 
by dyld at run time and it is also possible to ask dyld to display debug info 
about exactly what files it ends up using, among other things.  See the dyld 
man page for lots of useful info.  An example:

$ DYLD_PRINT_LIBRARIES=1 /opt/macports/bin/python3.9 -c "import 
_tkinter;print(_tkinter.__file__)" 2>&1 | grep 'libt'
dyld: loaded:  
/opt/macports/lib/libtcl8.6.dylib
dyld: loaded: <403FAC32-CB24-3ED3-B680-02AE4FBB11A7> 
/opt/macports/lib/libtk8.6.dylib

Hope this helps!

[issue44252] test_ssl and test_httplib.HTTPSTest crash randomly with "Windows fatal exception: access violation" on Windows

[STINNER Victor]

STINNER Victor  added the comment:

Maybe the problem is related to Python frames. I think Mark Shannon made 
changes related to frames recently in 3.10 and main branches.

It's strange that I got such error:

  File "C:\vstinner\python\main\lib\unittest\result.py", line 205, in 
_is_relevant_tb_level
return '__unittest' in tb.tb_frame.f_globals
TypeError: argument of type 'NoneType' is not iterable

It's also strange that two crashes occurred while reading a traceback:

Windows fatal exception: access violation

Current thread 0x09e0 (most recent call first):
  File "D:\a\1\s\lib\linecache.py", line 63 in checkcache
  File "D:\a\1\s\lib\traceback.py", line 375 in extract
  File "D:\a\1\s\lib\traceback.py", line 494 in __init__
  File "D:\a\1\s\lib\traceback.py", line 132 in format_exception
  File "D:\a\1\s\lib\test\test_ssl.py", line 262 in handle_error

and:

Fatal Python error: Segmentation fault

  File

 line 262 in handle_error

Extract of test_ssl.py:

def handle_error(prefix):
exc_format = ' '.join(traceback.format_exception(*sys.exc_info()))
...

Maybe sometimes somehow, frames are invalid.

Maybe test_ssl/test_httplib only makes the crash more likely, but there is a 
regression to frames somewhere.

[issue44252] test_ssl and test_httplib.HTTPSTest crash randomly with "Windows fatal exception: access violation" on Windows

[David Bolen]

David Bolen  added the comment:

The win10 buildbot appears to have this failure consistently (100%) on the 3.10 
branch.  The first such failure appears to be yesterday 
(https://buildbot.python.org/all/#/builders/600/builds/79), following commit 
da8097aaf5a55c23f5b5ddbeffc2d90d06e00d93 - GC changes for mmap.

I'm not yet having much luck reproducing manually (which is perplexing given 
the consistent failures during the automatic tests).  I did see one test run 
where 8 other tests failed instead, but haven't been able to repeat.  The 3.x 
branch also seems to be doing fine on the buildbot while including the same 
patch that was cherry picked for 3.10.

So this could be a false lead, but it might be another place to review.  Or for 
anyone who can at least sporadically get a failure (I'm still trying), 
something to try reverting.

asyncore and asynchat are deprecated since 3.6, so this is not going to be

[issue44253] tkinter searches for tk.tcl in wrong directory

[Adam Stewart]

Adam Stewart  added the comment:

And... now it's not working again. Can you clarify exactly how tkinter finds 
tk/tcl? Does it rely on TCL_LIBRARY or TK_LIBRARY env vars? TCLLIBPATH? If I 
use all of these env vars, tkinter finds tcl/tk, but commands like:

$ python -m tkinter
$ python -c 'import tkinter; tkinter._test()'

open a window and immediately minimize it. If I try to maximize the window it 
immediately closes, so something is definitely wrong with my installation.

[issue42627] urllib.request.getproxies() misparses Windows registry proxy settings

[狂男风]

狂男风  added the comment:

I removed the multi-proxies-per-protocol support from the PR I submitted. The 
reason is that:

1. This code reads the proxy settings from the Windows registry. 
Multi-proxies-per-protocol cannot be resolved by Windows system.
2. Using a comma-separated string for the multi-proxies-per-protocol support, 
is not backward compatible. Not only Windows, but Linux is also one proxy per 
protocol.

If you want to implement the multi-proxies-per-protocol support, then I think 
you should open another issue and make changes to all OS platforms.

As you can see the tar generated using the `tar` command are always same, 
instead the one generated using python are not.

Am I missing some arguments?

Thanks

[issue44261] SocketType documentation misleading

[Sebastian Rittau]

New submission from Sebastian Rittau :

The documentation of socket.SocketType 
(https://docs.python.org/3/library/socket.html?highlight=sockettype#socket.SocketType)
 is misleading. It states:

This is a Python type object that represents the socket object type. It is 
the same as type(socket(...)).

This is untrue. socket.SocketType is in reality re-exported from _socket, where 
it is an alias for class _socket.socket, a super type of class socket.socket. I 
think that either the documentation should be fixed, or SocketType should be 
moved to socket and made an alias of socket.socket.

[issue32779] urljoining an empty query string doesn't clear query string

[Paul Fisher]

Paul Fisher  added the comment:

Reading more into this, from section 5.2,1:

> A component is undefined if its associated delimiter does not appear in the 
> URI reference

So you could say that since there is a '?', the query component is *defined*, 
but *empty*. This would mean that assigning the target query to be '' has the 
desired effect as implemented by browsers and other languages' standard 
libraries.

[issue44252] test_ssl and test_httplib.HTTPSTest crash randomly with "Windows fatal exception: access violation" on Windows

[STINNER Victor]

STINNER Victor  added the comment:

Ken Jin:
"Sorry, I introduced the test_httplib regression on Windows with GH-26381 
commit 0fa282c55f1a45765340cb24ed65c90ffe2aa405. I made a second PR GH-26429 to 
fix it."

That would help to fix the issue, sadly the crash is earlier to your PR merge, 
and test_httplib doesn't use asyncio.

[STINNER Victor]

STINNER Victor  added the comment:

I'm not fully satified by the overlapped_dealloc() implementation neither. 
There is an unpleasant code path for Windows XP but it's no longer needed in 
Python 3.11. I would prefer to always call PyObject_GC_UnTrack() and call it 
earlier.

See the dicsussion in the PR:
https://github.com/python/cpython/pull/26381

But it can be modified later.

I'm not fully satisfied by the implementation of the two LRU types in

The _lru_list_elem doesnt implement the GC protocol for performance reasons:

But I'm not sure if it's ok that _lru_list_elem doesn't implement the GC 
protocol: it's disucssion in this issue.

[issue14965] super() and property inheritance behavior

[Aaron Gallagher]

Aaron Gallagher <_...@habnab.it> added the comment:

@daniel.urban would you kindly resubmit your patch as a PR to the cpython repo? 
I've learned out-of-band from someone else that putting patches on bpo is 
considered obsolete. you can use the PR I've submitted 
(https://github.com/python/cpython/pull/26194) and reset the author. 

I'd be happy to do it myself (giving you a branch that's all set up, so all you 
need to do is click the 'new PR' button) if you tell me what to set the author 
to.

[issue38575] Child process deadlock in subprocess.Popen

[Irit Katriel]

Irit Katriel  added the comment:

Python 2.7 is no longer supported and the code of subprocess has been changed a 
lot compared to what shows up in your traceback. Please create a new issue if 
you still see this problem in Python 3.9+.
