[issue31422] tkinter.messagebox and tkinter.filedialog don't show default button's keyboard shortcuts

[Terry J. Reedy]

Terry J. Reedy  added the comment:

jcr: 3.5 only gets security fixes.  If this issue does not apply to 3.6 or 3.7, 
this should be closed.  When core developers (snake after name) change the 
headers, you should assume that they know what they are doing and not change 
them back.

[issue31552] IDLE: Convert browswers to use ttk.Treeview

[Terry J. Reedy]

Terry J. Reedy  added the comment:

The main issue for conversion is expanding nodes.  tree.py does not define a 
widget class.  Rather, is uses a used a canvas and places images and text 
thereupon.  The latter is done with instances of TreeNode.  Each instance 
thereof is initialized with an instance of a subclass of TreeItem.  TreeItems 
can tell their TreeNode whether they can generate children without actually 
doing so.

Treeview *is* a widget which manages internal column and line structures.  
Clicking a [+] or [-] icon generates a '<>' or '<>' 
event.  Double clicking a line generates both a select and flip event.  The 
catch is that there is no [+] unless the node already has at least one child.

One solution would be to initially generate the whole tree of Treeview items 
from the pyclbr tree.  Another is to give items with children a dummy child and 
replace it on demand.  The item could be given its line number (as a string) as 
its id.  A subclass of Treeview (or a Frame containing one) could have a dict 
mapping ids to child dicts).

Since the browser TreeItem subclasses are used by pathbrowser, I would 
initially move them to that module rather than delete them.  Or I would combine 
the two modules.

[issue31552] IDLE: Convert browswers to use ttk.Treeview

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Two concrete reasons to make the conversion: two issues are stymied by current 
tree.TreeNode.

1. #25090 tree.TreeNode requires an icon for every line.  Hence functions and 
classes get python file and director icons and they are difficult to remove.  
By default, Treeview items do not get an image beside the text.

2. #20827 tree.TreeNode hardcodes single click behavior (in multiple places). 
TreeItems can only override or augment double clicks.  So it would be hard to 
keep hilites synchronized in browser and editor.  Treeview generates 
'<>' when a line is clicked on; setting the editor line can be 
done in a select handler.

[issue20827] IDLE : Display function argument list in ClassBrowser

[Terry J. Reedy]

Terry J. Reedy  added the comment:

As with removing icons (#25090), moving 'highlight line in editor' from double 
click to single click is not trivial.  Single click behavior is baked into 
tree.  TreeNode.  TreeItems can only override or augment double-click behavior. 
 I am deferring 'improve visibility of function argument list until I seriously 
look at ttk.Treeview (#31552).

I'm still unable to reproduce the bug.

I'm now monitoring the docs.python.org hierarchy whith a:

grep -rl 'définition' /srv/docs.python.org/ja/; grep -rl か 
/srv/docs.python.org/{2.7,3.6,3.7}

So if it happen again we'll maybe learn more, according to this simple grep the 
bug is not on production at this time on any page.

[issue31614] can't list groupby generator without breaking the sub groups generators

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Except for display the last few elements, this is the documented and intended 
behavior: ( https://docs.python.org/3/library/itertools.html#itertools.groupby 
):

'''
The returned group is itself an iterator that shares the underlying iterable 
with groupby(). Because the source is shared, when the groupby() object is 
advanced, the previous group is no longer visible. So, if that data is needed 
later, it should be stored as a list:

groups = []
uniquekeys = []
data = sorted(data, key=keyfunc)
for k, g in groupby(data, keyfunc):
groups.append(list(g))  # Store group iterator as a list
uniquekeys.append(k)
'''

The display of the last few elements isn't supposed to happen.  That is being 
fixed so that all of the subiterator results are empty when the parent iterator 
is exhausted.

[issue31613] tkinter.simpledialog default buttons (not buttonbox) are not localized, unlike all messagebox

[jcrmatos]

jcrmatos  added the comment:

Hello,

I would expect the same behaviour as askopenfilename from tkinter.filedialog 
where the buttons are localized (in my case in Portuguese).

What I get is the buttons (in tkinter.simpledialog) are always in English.

There is a difference in behaviour between messagebox windows (no shortcuts at

[issue31614] can't list groupby generator without breaking the sub groups generators

[Loïc Le Loarer]

New submission from Loïc Le Loarer :

If I "list" the itertools groupby generator, then the sub generators of each 
groups are all empty except the last one.

import itertools as i
L = ['azerty','abcd','ac','aaa','z','baba','bitte','rhum','z','y']
g = list(i.groupby(L, lambda x: x[0]))
number_of_groups = len(g)
ans = 0
for k, v in g: # This doesn't work
#for k, v in i.groupby(L, lambda x: x[0]): # This works
v = list(v)
print(k,v,len(v))
ans += 100*len(v)//number_of_groups
print(ans)
assert(ans == 163)
I don't understand why. Is my code broken ?

The need for saving the group generator first exists when I need the number of 
groups before walking thru the groups, like in the above example.

I have not been able to test to latest python versions, is the problem already 
fixed ?

I'd prefer to understand exacly what is going wrong and fix it, but I agree it 
would fix the issue and even fix the other hypothesis, so I don't exclude doing 
it, even if I find the root cause.

I'm currently doing a full build locally (I previously tried building using the 
Doc/Makefile, was unable to reproduce the bug, I'm now building using the 
build_docs.py script) it will take like an hour on my laptop, I'll see.

Julien Palard  added the comment:

Found another hypothesis: As the builds take a long time, builds may overlap 
(starting a build while another is still unfinished, typically rsync-ing its 
files), but this would result in:

- japanese being build while french being rsynced
- french being build while english being rsynced
- english being build while japanese being rsynced

This mean japanese on french pages, french on english pages, and english on 
japanese pages, which is the other way around, nobody spotted any of this 
overlaps, so I discard this hypothesis.

Thanks for those details.

Until we find japanese on a french page, or french on an english page, which 
would clearly disproove the hypothesis of a build picking up translated files 
from a previous build, I still consider this hypothesis the good one.

I'm also seeing pages like genindex-位.html on the english directory tree, which 
is less surprising : the english build may just not remove them.

[issue31612] Building 3.6 fails on Windows

[Steve Dower]

Steve Dower  added the comment:

If you install VS 2017 and select the "Python native development" option as 
described in the dev guide, you get the correct compilers (plural) for Python 
3.5 onwards. The build.bat file (specifically, the find_msbuild.bat helper) 
will choose the correct version.

You do not need to install VS 2015 anymore. VS 2015 and VS 2017 both include VC 
toolset v140, which is the officially supported compiler (the VS version is 
separate).

The error is coming from the Tcl makefile at these lines:

.SUFFIXES:
.SUFFIXES:.c .rc

I personally have no idea what these mean or why it is failing, and I don't 
even know what these are meant to do. But perhaps you have some file called 
".SUFFIXES" or similar that is causing the Tcl build to fail?

[issue31611] Tests failures using -u largefile when the disk is full

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

largefile - It is okay to run some test that may create huge
files.  These tests can take a long time and may
consume >2GB of disk space temporarily.

I understand this as 2GB is a minimum free disk space for tests without 
"largefile". Tests with "largefile" need more free disk space.


Accordingly the bigmemtest decorator is used for tests that consume >1GB of RAM.

I don't think this is worth adding a separate command.

If some controls were needed (changing the list size has not been requested 
before), it may be better to follow gdb with set/get commands that could be 
used for other parameters as well.

[issue23239] SSL match_hostname does not accept IP Address

[Alex Gaynor]

Alex Gaynor  added the comment:

I'd be in favor of backporting this to the 2.x - encouraging reliance on the 
nonsense behaviour of putting IPAddresses in DNS Names or relying on CN over 
SAN is bad, and we shouldn't encourage it.

spotted the bug on production neither. If anyone see it please write down the

Did the strings were all over the page, or only a few strings on a normally

[issue31612] Building 3.6 fails on Windows

[STINNER Victor]

STINNER Victor  added the comment:

To compile Python 2.7, you need VS 2008 *and* 2010.

To compile Python 3.5, 3.6 or master, you need VS 2015.

To compile Python 3.4, you need VS 2010.

I had to work on Python 2.7, 3.4, 3.5, 3.6 and master, so I installed VS 2008, 
2010 and 2015 :-)

I didn't give a try to VS 2017 yet. I'm fine with 3 VS versions installed in

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Definitely the test shouldn't be quietly skipped! If you enable the "largefile" 
resource, but the test can't write large file, this is either a bug in the 
tested code, or an error in the test, or misconfiguration.

We already have the "extralargefile" resource which is excluded from "all". 
"largefile" is for moderately large files, around 2 GiB.

[issue31580] Defer compiling regular expressions

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

I'm closing this experiment.

I'm not convinced that even if we can make start up time faster for module 
global regular expressions, we'll ever get enough buy-in from the ecosystem to 
make this worth it, because you'd really want to get all your dependencies 
converted, and that would take years, especially since any wins wouldn't be 
possible until Python 3.7.

[issue31611] Tests failures using -u largefile when the disk is full

[STINNER Victor]

STINNER Victor  added the comment:

> This is expected behavior, isn't?

I would prefer that the test skips itself when the disk is full: on "OSError: 
[Errno 28] No space left on device".

Or maybe largefile resource should be excluded from "all"... at least on 
Windows, since NTFS doesn't see to support files full of zeros without 
accounting zero bytes (seek + write 1 byte: NTFS counts the seek in the disk 
space).

[issue31607] Add listsize in pdb.py

[Stéphane Wirtel]

Stéphane Wirtel  added the comment:

Hi David,

It's my fault and you are right, I didn't give the right description.

By default when you want to list the source code with pdb, you will use the 
list command but this one is just limited to the 10 next lines and there is no 
possibility to change this limit of 10 lines.

We can play with the second parameter of pdb, examples:

* list 10, 11
will show the code from the line 10 to 11

* list 10, 50
will show the code from the line 10 to 50

* list 10, 5
will show the code from the line 10 and the next 5 lines.

* list
will show from the current position and the next 10 lines.

and my first question was, why this limit exists? Could we change that?

after, I have read the doc of gdb and I have seen there was a "set linesize 
count" option where you can configure the number of lines to show.

Here is the reason of my proposal.

For the configuration of pdb, I am interested, I know we can use the .pdbrc 
file but it is really interesting if we desire to add new aliases or add new 
commands for the breakpoints.


Here is an other example for this issue:

./python -m pdb demo.py
 
> demo.py(1)()
-> import os
(Pdb) listsize 5
List size: 5
(Pdb) l
  1  -> import os
  2 import sys
  3 
  4 def main():
  5 print(f"CWD: {sys.getcwd()}")
  6 print(f"PID: {sys.getpid()}")
(Pdb) l
  7 
  8 if __name__ == '__main__':
  9 main()
[EOF]
(Pdb)

[issue31607] Add listsize in pdb.py

[R. David Murray]

R. David Murray  added the comment:

It isn't obvious from your description here what 'listsize' does.  I think you 
should have provided some more motivating details :)

Looking at your PR, this is essentially a configuration setting.  I wonder if 
we should think about the general problem rather than continuing to clutter the 
top level command namespace.  (The only current example of this I spotted in 
the pdb docs is display/undisplay.)

This is probably a topic for the python-ideas mailing list.  For example, 
rather than complicating input, it might be better to propose adding a 
redirect_stdin to contextlib to parallel the two existing redirect context 
managers.  I don't remember why that was not added when the others were, but 
there was probably a reason, so a discussion about what the best solution is 
for the use case is in order, and python-ideas is the place for that.

[issue31610] Use select.poll instead of select.select in SocketServer.BaseServer.serve_forever

[Беатрис Бонева]

New submission from Беатрис Бонева :

The select function does not work for file descriptors with number >= 1024. It 
has FD_SETSIZE limit (see 
https://stackoverflow.com/questions/7976388/increasing-limit-of-fd-setsize-and-select#7977082).
So, serve_forever won't work if more than 1024 file descriptors are opened in 
the process (ValueError: filedescriptor out of range in select() is raised).
Moreover, the select function is considered inefficient, hard to scale and 
old-fashioned nowadays. Refer to 
https://stackoverflow.com/questions/970979/what-are-the-differences-between-poll-and-select#3951845.
Better alternative will be to use poll or epoll even.

[issue31608] crash in methods of a subclass of _collections.deque with a bad __new__()

[Oren Milman]

New submission from Oren Milman :

The following code causes the interpreter to crash:

import _collections
class BadDeque(_collections.deque):
def __new__(cls, *args):
if len(args):
return 42
return _collections.deque.__new__(cls)

BadDeque() * 42

(The interpreter would crash also if we replaced 'BadDeque() * 42' with
'BadDeque() + _collections.deque([42])'.)

This is because deque_copy() (in Modules/_collectionsmodule.c) returns whatever
BadDeque() returned, without verifying it is a deque.
deque_repeat() assumes that deque_copy() returned a deque, and passes it to
deque_inplace_repeat(), which assumes it is a deque, and crashes.

(Similarly, deque_concat() assumes that deque_copy() returned a deque, which
is the reason for the other crash.)


ISTM it is a very unlikely corner case, so that adding a test (as well as
a NEWS.d item) for it is unnecessary.
What do you think?

[issue31588] SystemError in class creation in case of a metaclass with a bad __prepare__() method

[Oren Milman]

Oren Milman  added the comment:

Nick, maybe you tried to reproduce in release?
In debug (where I got the SystemError), you have in the beginning of 
_PyFrame_New_NoTrack():
#ifdef Py_DEBUG
if (code == NULL || globals == NULL || !PyDict_Check(globals) ||
(locals != NULL && !PyMapping_Check(locals))) {
PyErr_BadInternalCall();
return NULL;
}

[issue31588] SystemError in class creation in case of a metaclass with a bad __prepare__() method

[Nick Coghlan]

Nick Coghlan  added the comment:

There's no __prepare__ method in 2.7, so that version can't be affected by this.

For 3.6 and 3.7, I can't reproduce the reported SystemError. Instead, I get:

```
>>> class BadMetaclass(type):
... def __prepare__(*args):
... pass
... 
>>> class Foo(metaclass=BadMetaclass):
... pass
... 
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 1, in Foo
TypeError: 'NoneType' object is not subscriptable

```

The error remains the same if I add `@classmethod` to the __prepare__ 
definition.


That's still thoroughly cryptic and worth changing, but indicates the test 
should be checking the error message details, not just the error type.

[issue31604] unittest.TestLoader().loadTestsFromTestCase(...) fails when adding test cases with the expectedFailure decorator

[Erasmus Cedernaes]

New submission from Erasmus Cedernaes :

How to reproduce:
* Run the attached file with Python 2.7 without any modifications. This will 
produce an error, as described below.
* Uncomment line 2 (the decorator @unittest.expectedFailure) and run the file 
with Python 2.7. This will not produce an error.

Description:
Adding the decorator @unittest.expectedFailure to a unittest.TestCase causes 
the TestLoader().loadTestsFromTestCase(...) to fail with the following output:

===
$ python2.7 mwe.py
Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 174, in _run_module_as_main
"__main__", fname, loader, pkg_name)
  File "/usr/lib/python2.7/runpy.py", line 72, in _run_code
exec code in run_globals
  File "[...]/mwe.py", line 12, in 
tests = unittest.TestLoader().loadTestsFromTestCase(TestClassThatFails)
  File "/usr/lib/python2.7/unittest/loader.py", line 50, in 
loadTestsFromTestCase
if issubclass(testCaseClass, suite.TestSuite):
TypeError: issubclass() arg 1 must be a class
==

The error does only occur when adding the test manually to a test suite. 
Running unittest.main(), does not produce the error.
