[issue42225] Tkinter hangs or crashes when displaying astral chars

[Ronald Oussoren]

Ronald Oussoren  added the comment:

W.r.t. the SyntaxError I got (msg380552): It looks like it will be possible to 
work around that problem in _tkinter.c:unicodeFromTclStringAndSize by merging 
surrogate pairs.

[issue42225] Tkinter hangs or crashes when displaying astral chars

[Ronald Oussoren]

Ronald Oussoren  added the comment:

Note that the main installers for Python 3.8 and 3.9 will continue to use Tk 
8.6.8 due to problems when building later Tk version on macOS 10.9.  

The current plan is to add an installer variant to (amongst others) uses Tk 
8.6.10 (and .11 when that's released).

[issue42179] Clarify chaining exceptions in tutorial/errors.rst

Inada Naoki  added the comment:

> OK, I will send this topic to python-dev first.

For the record, there is a long thread in python-dev about this issue:

* main thread: 
https://mail.python.org/archives/list/python-...@python.org/thread/MXMEFFYB6JXAKSS36SZ7DX4ASP6APWFP/
* another thread: 
https://mail.python.org/archives/list/python-...@python.org/thread/WNHVZLEO3ZVDOFP2FHRBUQR4GY24RIJJ/

## High level discussion: focus on new user vs write more and more details.

More detail:
* Abdur-Rahmaan Janhangeer

Focus on new user:
* Paul Moore 
* Brett Cannon
* Guido van Rossum
* Kyle Stanley
* Carol Willing
* Serhiy Storchaka

## About this specific case. (Adding __context__ and __suppress_context vs 
removing __cause__)

Add __context__:
(no one)

Remove __cause__:
* Kyle Stanley
* Éric Araujo (in GH-23160)

Riccardo Polignieri asked that to be very careful about removing something, but 
he did not vote for adding __context__ and __supress_context__.

I merged PR-23162 for keep focus on new users and consistent for now.

But I have not closed this issue yet because documentation WG may revisit the 
issue. (see

[issue42289] Found a secret/private key in code.

[Zachary Ware]

Zachary Ware  added the comment:

That commit does not appear to be part of any branch of the main repository, 
and also appears to contain non-changes to every file in the repository.

There are known private keys somewhere in Lib/test for use in tests.  If you're 
referring to something else, please point it out a bit more clearly, preferably 
with a link directly to the file :)

If you're talking about accidentally committing your own private key to your 
personal fork of the repo, your best course is probably to delete your fork and 
re-fork, though I don't know if that will actually make that commit go away 
forever; you'd need to talk to GitHub about that.

[issue42293] Installation of pyinstaller in Windows fails with utf8 error

[Eryk Sun]

Eryk Sun  added the comment:

This looks to be a bug in the constructor of pip's BuildEnvironment class:

https://github.com/pypa/pip/blob/a4f4bfbf8ba7fd1e60884a439907e3f2a32e117a/src/pip/_internal/build_env.py#L82

Python 3 source files are UTF-8 by default, but text files default to the 
platform's preferred encoding, unless overridden by Python's UTF-8 mode. It is 
thus a mistake to create "sitecustomize.py" without explicitly specifying UTF-8 
as the encoding. 

The preferred encoding in Windows is the process active code page, which is the 
system code page, unless, in Windows 10 only, it's overridden to use UTF-8 by 
the application manifest's "activeCodePage" setting. The system code page is 
usually a legacy code page, such as 1252, unless, in Windows 10 only, it's set 
to UTF-8 or the system language is Unicode only (e.g. Hindi).

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Serhiy, does Ronald's report above re 8.6.10 on macOS suggest what might be 
needed to make print("") work on Mac?  As I remember, your year-old _tkinter 
patch to make print() work on Linux and Windows converts Python strings 
differently on the two systems.  But you did not know for sure what to do for 
macOS because nothing would work.

[issue42293] Installation of pyinstaller in Windows fails with utf8 error

[giomach]

New submission from giomach :

Python 3.9 freshly installed in Windows 10 to C:\Program Files\Python39, 
everything done as administrator, installed for all users, added to PATH.

Installation of pyinstaller fails with message "SyntaxError: (unicode error) 
'utf-8' codec can't decode byte 0xe1 in position 0: unexpected end of data 
(sitecustomize.py, line 21)" (attachment)

This may be due to the character á in my Windows username (0xe1 in ANSI, which 
is my default 8-bit codepage) being misinterpreted as being in utf8 instead of 
ANSI.

There is no sitecustomize.py in my file system.

[issue42288] typing.get_type_hints() returns Optional[Any] if the default value of the argument is None

[Guido van Rossum]

Guido van Rossum  added the comment:

There is actually a difference between Any and Optional[Any]. Try the following 
using e.g. mypy:

def f(a: Optional[Any]):
a+1

def g(a: Any):
a+1

You'll get an error in f but not in g.

So this behavior is not a bug.

[issue42292] C API: Allocating Objects on the Heap. Misleading documentation.

[igo95862]

New submission from igo95862 :

The issue is that the function names are too similar to other function that do 
completely different things.


`PyObject_Init` this function does not use `__init__` at all.
What it does is sets the already allocated object pointer to the specific type 
and increments its reference.


`PyObject_New` this function has nothing to do with `__new__`. It mallocs the 
new object and when calls `PyObject_Init` to set its type and increment 
reference.


Most importantly neither function actually calls `__init__`. You need to do it 
manually otherwise you might get garbage in your object data from residual 
memory.


I think there should be a small example showing how to allocate objects on heap 
and initialize them. This is what I do (ignore the names):


```
SdBusMessageObject *message_object = PyObject_NEW(SdBusMessageObject, 
);
SdBusMessageType.tp_init((PyObject *)message_object, NULL, NULL);
```

[issue41116] build on macOS 11 (beta) does not find system-supplied third-party libraries

[Ronald Oussoren]

Ronald Oussoren  added the comment:

So close...

the problem we're running into is that "-isysroot" is only added for universal 
builds, not for regular builds. Furthermore unixccompiler doesn't know that is 
should always look in the SDK and not in the regular location (for system 
locations). 

I guess we should switch to:
- Never add -isysroot to CFLAGS (change to configure)
- Teach _osx_support about locating the default sdk root, both for Xcode and 
"command line tools" (_osx_support.default_sdk_root())
- Use that new function in setup.py and unixccompiler.

The first item might affect older systems where Xcode shipped with 2 SDKs 
(current and previous OS version). 

Is that something we can back port to 3.8 and 3.9? 

A less clean, but smaller, change is to teach the configure script to always 
add -isysroot on macOS, not just when doing a universal build.

[issue42142] test_ttk timeout: FAIL tkinter ttk LabeledScale test_resize, and more

[E. Paine]

E. Paine  added the comment:

This is starting to get *very* annoying. Today's failure was a new one (but 
still `wait_visibility`):

test_variable_change (tkinter.test.test_ttk.test_extensions.LabeledScaleTest) 
... Timeout (0:20:00)!
Thread 0x7f31dade1080 (most recent call first):
  File "/home/runner/work/cpython/cpython/Lib/tkinter/__init__.py", line 696 in 
wait_visibility
  File 
"/home/runner/work/cpython/cpython/Lib/tkinter/test/test_ttk/test_extensions.py",
 line 147 in test_variable_change

Again, this was on the Github Ubuntu test 
(https://github.com/python/cpython/pull/23200/checks?check_run_id=1370499785#step:10:912).
 I will update my PR to skip *all* tests that use `wait_visbility` on Ubuntu 
and ask that this would be committed sooner rather than later.

[issue42278] Remove usage of tempfile.mktemp in stdlib

[E. Paine]

E. Paine  added the comment:

> Most of them are in tests. There is no security issue there
TBH, I don't know enough about the exploit to comment, but it seems that the 
tempfile tests take this seriously (Lib/test/test_tempfile.py:782 "For safety, 
all use of mktemp must occur in a private directory.")

> distutils and msilib are dropped
Is this wise? As you noted, PEP 594 and PEP 632 have yet to be approved (in 
which case, should we not still be looking at these modules, particularly as 
PEP 594 has been around for a while).

> if someone wants to fix pydoc

I am currently drafting a PR which will replace it with `NamedTemporaryFile` 
(and while we're at it, replace the `os.system` call with `subprocess.run`)

[issue42225] Tkinter hangs or crashes when displaying astral chars

[Ronald Oussoren]

Ronald Oussoren  added the comment:

The crash I had on macOS with tk 8.6.8 appears to be gone when using tk 8.6.10.

What I got back was a SyntaxError when pasting a smiley emoji in an IDLE shell 
window when trying to type execute print("").  The SyntaxError message says: 
'utf-8' codec can't encode characters in position 7-12: surrogates not allowed. 
 That's likely to to how Tk represents this character in its text widget, and 
is something we could work around when converting Tcl/Tk strings to Python 
strings.

Printing the emoji using 'print(chr(128516))' works fine.

The scriptlet in msg380173 also works.

[issue42225] Tkinter hangs or crashes when displaying astral chars

[Ronald Oussoren]

Ronald Oussoren  added the comment:

I've filed a Tk issue about this: 
https://core.tcl-lang.org/tk/tktview/f9fa92d8e06972b5f0583b07a3c98eaac0a0

What versions of Tk are used? 
- On macOS I've tested with the  Python.org installer, which uses Tk 8.6.8.

[issue42225] Tkinter hangs or crashes when displaying astral chars

[Ian Strawbridge]

Ian Strawbridge  added the comment:

Further to the information I posted on Stack Overflow (referred to above) 
relating to reproducing emoticon characters from Idle under Ubuntu, I have done 
more testing.  Based on some of the code/comments above, I tried modifications 
which I hoped might identify errors before Idle crashed.
At a simple level I can generate some error information in a Ubuntu terminal 
from the following.
usr/bin$ idle-python3.8
Entering chr(0x1f624) gives the following error message in terminal.
X Error of failed request:  BadLength (poly request too large or internal Xlib 
length error)
  Major opcode of failed request:  139 (RENDER)
  Minor opcode of failed request:  20 (RenderAddGlyphs)
  Serial number of failed request:  4484
  Current serial number in output stream:  4484

Another test used this code.
--
def FileSave(sav_file_name,outputstring):
with open(sav_file_name, "a", encoding="utf8",newline='') as myfile:
myfile.write(outputstring)

def FileSave1(sav_file_name,eoutputstring):
with open(sav_file_name, "a", encoding="utf8",newline='') as myfile:
myfile.write(eoutputstring)

tk = True
if tk:
from tkinter import Tk
from tkinter.scrolledtext import ScrolledText
root = Tk()
text = ScrolledText(root, width=80, height=40)
text.pack()
def print1(txt):
text.insert('insert', txt+'\n')

errors = []
outputstring = "Characters:"+ "\n"+"\n"
eoutputstring = "Errors:"+ "\n"+"\n"

#for i in range(0x1f600, 0x1f660):   #crashes at 0x1f624
for i in range(0x1f623, 0x1f624):  # 1f624, 1f625 then try 1f652  
chars = chr(i)
decimal = str(int(hex(i)[2:],16))
try:
outputstring = str(hex(i))+" "+decimal+" "+chars+ "\n"
FileSave("Charsfile.txt", outputstring)
print1(f"{hex(i)} {decimal} {chars}")
print(f"{hex(i)} {decimal} {chars}")
except Exception as e:
print(str(hex(i)))
eoutputstring = str(hex(i))+ "\n"
FileSave1("Errorfile.txt", eoutputstring)
errors.append(f"{hex(i)} {e}")

print("ERRORS:")

for line in errors:
print(line)

--
With the range starting at 0x1f623 and changing the end point, in Ubuntu, with 
end point 0x1f624, this prints ok, but if higher numbers are used the Idle 
windows all closed. However on some occasions, if I began with end point at 
0x1f624 and run, then without closing the editor window I increased the end 
point to 0x1f625, save and run, the Text window would close, but the console 
window would remain open.  I could then increase the upper range further and 
repeat and more characters would print to the console.
I have attached screenshots of the console output with the 
fonts-noto-color-emoji fonts package installed(with font), then with this 
package uninstalled (no font) and finally the same when run under Windows 10.  
For the console output produced while the font package is installed, if I 
select in the character column where there is a blank space, "something" can be 
selected.  If I save the console as a text file or select all the rows, copy 
and paste to a text file, the missing characters are revealed. When the font 
package is uninstalled, the missing characters are truely missing.  It is the 
apparently missing characters (such as 0x1f624, 0x1f62c, 0x1f641, 0x1f642, 
0x1f644-0x1f64f) which appear to be causing the Idle crashes.  Presumably such 
as 0x1f650 and 0x1f651 are unallocated codes so show up as rectangular 
outlines. 

In none of the tests with the more complex code above did I manage to generate 
any error output.

My set up is as follows.
Ubuntu 20.04.1 LTS
x86_64
GNOME version: 3.36.3
Python 3.8.6 (default, Sep 25 2020, 21:22:01) 
Tk version: 8.6.10
[GCC 7.5.0] on linux

Hopefully, the above might give some pointers to handling these characters.

[issue42291] Incorrect signature of CodeType.replace()

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

Currently the signature of types.CodeType.replace() is

replace(self, /, *, co_argcount=-1, co_posonlyargcount=-1, 
co_kwonlyargcount=-1, co_nlocals=-1, co_stacksize=-1, co_flags=-1, 
co_firstlineno=-1, co_code=None, co_consts=None, co_names=None, 
co_varnames=None, co_freevars=None, co_cellvars=None, co_filename=None, 
co_name=None, co_lnotab=None)

But -1 and None are incorrect values for many parameters, and even if they 
would be correct, they are not default values. By default, if you do not 
specify some argument, the value of the corresponding attribute would not be 
changed.

Argument Clinic and the inspect module do not support this case.

[issue42283] test_idle is interactive on macOS 11

[Ronald Oussoren]

Ronald Oussoren  added the comment:

I was using a Tk 8.6.8 build on macOS 11. Looking at this more closely there 
are clearly other problems with that build: All windows that were created by 
the test were completely black except for the window chrome. 

@terry.reedy: I got those crash reporter pop-ups as well, they seem to be 
related to tests where the interpreter is made to crash as part of the test 
(for example in the concurrent.futures tests).  I hope we can find a way to 
suppress those pop-ups.

[issue42278] Remove usage of tempfile.mktemp in stdlib

[Steve Dower]

Steve Dower  added the comment:

Yeah, once tests are excluded and the (deprecated or nearly deprecated) 
distutils and msilib are dropped, the problems are pydoc (which looks 
non-exploitable) and anywhere we need to generate a named pipe.

Both cases where named pipes are being created are as safe as the OS allows, so 
it's really just pydoc that might deserve a fix. (For reference, it's in the 
variation of help() that writes the docstring to a file and triggers the 
equivalent of "type  | more" or "cat  | less", which is already 
only useful in an interactive shell.)

So I'd suggest it's already as low as possible, but if someone wants to fix 
pydoc (and encourage the SC to approve PEP 594 and PEP 632 so we don't have to 
worry about msilib or distutils) then they can feel free.
