[issue43662] test_tools: test_reindent_file_with_bad_encoding() fails RHEL7 on x86-64 and s390x with GCC 4.8.5 and LTO

[STINNER Victor]

STINNER Victor  added the comment:

This issue should be fixed by:

commit 92a02c1f7e2dcdc62913a4236589e7e5d96172b9
Author: Pablo Galindo 
Date:   Tue Mar 30 00:24:49 2021 +0100

Fix tokenizer error when raw decoding null bytes (GH-25080)

The fix is the usage of strlen() instead of "tok->end - tok->cur" to compute 
the line length.

> https://buildbot.python.org/all/#/builders/244/builds/931

The latest 6 builds are successful. I close the issue.

[issue43665] AIX: test_importlib regression (ENV change)

[Michael Felt]

New submission from Michael Felt :

Since issue43517 test_importlib 'fails' (bot status) with ENV_CHANGED.

The core dump is caused by SIGTRAP. I need help to learn how to stop the core 
dump from being cleaned up so I can load it into dbx and hopefully 
understand/learn with sub-test is actually having issues.

e.g., see 
https://buildbot.python.org/all/#/builders/438/builds/1031/steps/5/logs/stdio 
for current bot exit status

Thx for assistance.

[issue43665] AIX: test_importlib regression (ENV change)

[STINNER Victor]

STINNER Victor  added the comment:

A core dump is a very bad sign of health.

Can you please try to bisect which test is causing the segfault using 
bisect_cmd? Try the command:

./python -m test.bisect_cmd -o bisect --fail-env-changed test_importlib

The command should takes 10-60 minutes, and you should see the number of tests 
decreasing. I hope that at the end, the command will identify a single method 
triggering the crash.

At the end, the create "bisect" file contains the test methods causing the bug.

Then you can re-run tests with:

./python -m test --fail-env-changed test_importlib --matchfile=bisect


> The core dump is caused by SIGTRAP. I need help to learn how to stop the core

You can re-run the test without libregrtest by running it directly. Example:

./python -m test.test_importlib 
test_spec.Frozen_ModuleSpecMethodsTests.test_reload -v

It should create a core dump in the current directory, or you run the command 
in your favorite debugger.

[issue19124] os.execv executes in background on Windows

[Eryk Sun]

Eryk Sun  added the comment:

Steve, what do you think about os.exec*()? Should it be emulated better or 
deprecated? 

We can't hide the reality that it's a new process with a different process ID 
and parent process ID -- against what POSIX requires. But emulating exec() is 
probably good enough for most cases, especially if code expects to work in 
Windows.

> I like the idea, but we shouldn't invert the dependencies like that. 
> nt/os is a lower-level library, and should provide its own 
> implementation (that perhaps subprocess could then use).

The precedent I had in mind is os.popen(), which uses subprocess.

There wouldn't be much need to implement system() and spawnv[e] if ucrt used 
PROC_THREAD_ATTRIBUTE_HANDLE_LIST in the common spawn code (exec\spawnv.cpp). 
Any chance that's in development or planned?

If Python implements its own system() and spawnv[e]() functions, support for 
inheritable file descriptors [1] would probably have to be dropped. That's not 
a great loss, IMO, but I'm sure someone will be unhappy about it. The problem 
is that the flags for an open fd (e.g. FDEV, FPIPE, FAPPEND, FTEXT, 
FNOINHERIT), which the CRT copies to the STARTUPINFO.lpReserved2 buffer, are 
not public data. In particular, the FAPPEND flag for an O_APPEND open can't be 
determined or inferred.

---

[1] Making an fd inheritable currently requires two steps in Windows Python: 
fd2 = os.dup(fd); os.set_inheritable(fd2, True). os.dup(fd) creates a duplicate 
fd that's not flagged FNOINHERIT, but the underlying OS handle isn't 
inheritable. os.set_inheritable(fd, True) makes the OS handle inheritable, but 
it can't remove the FNOINHERIT fd flag.

New submission from Michael Felt :

When working in a WPAR (workload partition) the routines supporting 
aix_platform() may fail if there is no related builddate for bos.mp64.

a) the fileset queried is changed to `bos.rte`
b) an extreme value (9988) is returned for any similar (unexpected) situations 
- so that, in any case, the build of Python can proceed.

Recently, the situation has changed. We should consider this issue again.

typing.SupportsComplex is an ABC with one abstract method __complex__.
Thus, isinstance(complex, typing.SupportsComplex) is False.

[issue43622] TLS 1.3, client polling returns event without data

[gchauvel]

gchauvel  added the comment:

Based on your first comment, poll returning an event and recv not able to read 
data is a behavior to expect with TLSv1.2/TLSv1.3 (or ...)
So in order to use SSLContext in a polling loop with multiple file descriptors, 
a non-blocking mode (to avoid an fd event and not being able to read data) is 
mandatory. Do you agree with this statement ?

Furthermore, I looked at [1], the other tests in test_ssl.py and also set a few 
traces in _ssl.c

- without non blocking mode: even with a fd event, the test blocks on SSL_read
- with non blocking mode: SSL_read returns a negative value, PySSL_SetError 
throws PySSLWantWriteErrorObject, but:

nothing is printed on the console, a thread is blocked at 
PyThread_acquire_lock_timed, so the test hangs forever.

- with non blocking mode + try/except ssl.SSLWantReadError [2], the test is ok

Oh I see. Did not think about that. I can see a scenario where you install 3.9, 
PATH is set, you install 3.10, the PATH update fails for some reason and then 
you get stuck because PATH was not updated correctly... and then you're back to 
manually setting PATH which was the thing we were trying to prevent ...

Good to know, thanks. That was one of my concerns actually.

I'm sorry to hear that and I apologize - I was simply trying to get answers.

Well, now that I know why the box is not ticked, I can say I'm happy with the 
state of the installer, and I guess I'll continue to teach my students about 
PATH - after all, it's a useful skill to have ;)

[issue43667] Solaris: Fix broken Unicode encoding in non-UTF locales

[Jakub Kulik]

New submission from Jakub Kulik :

On Linux, wchar_t values are mapped to their UTF-8 counterparts; however, that 
does not have to be the case as the standard allows any arbitrary 
representation to be used, and this is the case for Solaris.

In Oracle Solaris, the internal form of wchar_t is specific to a locale; in the 
Unicode locales, wchar_t has the UTF-32 Unicode encoding form, and other 
locales have different representations [1].

This is an issue because Python expects wchar_t to correspond with Unicode, 
which on Oracle Solaris with non-UTF locale results either in errors (values 
are outside the Unicode range) or in output with different symbols.

Unicode locales work as expected, but they are not an acceptable workaround for 
some Oracle Solaris users that cannot use Unicode encoding for various reasons.


Because of that, we fixed it a few months ago with a patch to 
`PyUnicode_FromWideChar`, which handles conversion to unicode (attached in PR). 
It was tested over the last half a year, and we didn't see any related issues 
since.

Is something like this acceptable or should it be fixed on a different place/in 
a different way? All comments are appreciated.

[issue43667] Solaris: Fix broken Unicode encoding in non-UTF locales

[Jakub Kulik]

Jakub Kulik  added the comment:

I forgot to mention: this affects Oracle Solaris. I tested this on SmartOS, and 
I cannot reproduce it there as it seems that they are using Unicode 
representation for all locales. Based on the documentation, this might also 
affect other systems as well (e.g. HP UIX specifically says: 'These values may 
not be compatible with values obtained by specifying other locales that are 
supported'), but it's hard to tell without testing that.

This one liner breaks with ValueError: character U+3069 is not in range 
[U+; U+10] if the issue is present:
python3.7 -c 'import datetime; import locale; 
locale.setlocale(locale.LC_ALL,"es_ES.ISO8859-1"); datetime.date(2001, 1, 
3).strftime("%a")'

[issue43668] Segfault with for fresh ubuntu 20.04 install

[axel]

New submission from axel :

The python interpreter segfaults when running in a miniconda environment on a 
fresh install of ubuntu 20.04.2. This seems to happen intermittently, both 
while running "pip" during the conda setup of an environment and during the 
execution of code like below. The issue is most have mostly been reproduced 
with conda, but seems to happen regardless, which is why I suspect it is a 
python bug. It is very odd that I can't seem to find anyone else with the same 
issue.

The segfault always occurs when running the following code, which reads texts 
from files and tokenizes the result. The segfault location changes from run to 
run. Also the exact same code can run on another computer with the same conda 
environment on a ubuntu 18.04.

The core dumps always points to some function in the unicodeobject.c file in 
python but the exact function changes from crash to crash. At least one crash 
has a clear dereferenced pointer 0x0 where the "unicode object" should be.

My guess is that something causes the python interpreter to throw away the 
pointed to unicode object while it is still being worked on causing a segfault. 
But any bug in the interpreter or NLTK should have been noticed by more users, 
and I cannot find anyone with similar issues. 

Things tried that didn't fix the issue:
1. Reformatting and reinstalling ubuntu
2. Switched to ubuntu 18.04 (on this computer, another computer with 18.04 can 
run the code just fine)
3. Replacing hardware, to ensure that RAM, or SSD disk isn't broken
4. Changing to python versions 3.8.6, 3.8.8, 3.9.2
5. Cloning the conda environment from a working computer to the broken one

Attached is one stacktrace of the fault handler along with it's corresponding 
core dump stack trace from gdb.

[issue43668] Segfault with for fresh ubuntu 20.04 install

[STINNER Victor]

STINNER Victor  added the comment:

This is very likely a crash in a 3rd party C extensions. You should try to 
write a simpler reproducer and report it to the C extensions causing the crash. 
You can try to enable the Python Development Mode to see if it provides you 
more information:
https://docs.python.org/dev/library/devmode.html

See also my notes on debugging a Python crash:

Python no longer create "not ready" strings: _PyUnicode_Ready() is called to 
convert strings created with the deprecated legacy C API. It is likely a string 
created by a 3rd party C extension.

"begin=0x0 and end=0x4" sounds like the string is corrupted: in 
_PyUnicode_Ready(), _PyUnicode_WSTR(unicode) must not be NULL (begin=0x0).

Thanks for the reply, I don't know exactly what you mean by making a simpler 
reproducer, but as I wrote in the original post, just using pip will cause this 
issue to happen from time to time, which is why I find it unlikely to be caused 
by third party libs. 

I will try to cause a reproduction without 3rd party libs but since I don't 
have a good idea of what is causing it, I'm not really sure where to start.

[issue43510] PEP 597: Implemente encoding="locale" option and EncodingWarning

[Inada Naoki]

Inada Naoki  added the comment:

In bpo-43651, I found code pattern that it's difficult to use 
io.text_encoding():

class OpenWrapper:
def __new__(cls, *args, **kwargs):
return open(*args, **kwargs)

`kwargs["encoding"] = text_encoding(kwargs.get("encoding)` doesn't work because 
`open(filename, "b", encoding="locale")` raises `ValueError: binary mode 
doesn't take an encoding argument`.

I think we should accept `encoding="locale"` even in binary mode. It makes easy 
to use `text_encoding()` and `encoding="locale"`.

pip is a 3rd party project using 3rd party C extensions.

"3rd party" means "not maintained by python.org" (not part of the stdlib). See 
also:

Set PYTHONDEVMODE=1 in your ~/.bashrc, to run all Python applications with the

[issue36384] ipaddress Should not reject IPv4 addresses with leading zeroes as ambiguously octal

[Christian Heimes]

Christian Heimes  added the comment:

Serhiy was right, this is a security issue.

The patch should not have landed in 3.8. At a bare minimum the patch should 
have been postponed until documentation was updated. Since 3.8 the ipaddresss 
does not behave as documented. A similar security issue in NPM was published 
two days ago, CVE-2021-28918.

I proposed to not only revert the change, but also tighten the check for 
leading zeros so it behaves like glibc's inet_pton(). It refuses any IPv4 
string with a leading zero.

>>> socket.inet_pton(socket.AF_INET, "01.1.1.1")
Traceback (most recent call last):
  File "", line 1, in 
OSError: illegal IP address string passed to inet_pton
>>> socket.inet_pton(socket.AF_INET, "1.1.1.01")
Traceback (most recent call last):
  File "", line 1, in 
OSError: illegal IP address string passed to inet_pton

Is there anything else I should be doing, in order to get this merged in time

For the record, the equivalent PR for PyPy is now merged in the py3.7 branch: 
https://foss.heptapod.net/pypy/pypy/-/merge_requests/807.

Regarding the backporting, I understand from the devguide this is done 
automatically from GitHub labels (nice!), but it does not look like I have the

assert is_forking(sys.argv), "Not forking"

if sys.platform == 'win32':

else:
source_process = None
try:

[issue33125] Windows 10 ARM64 platform support

[Steve Dower]

Steve Dower  added the comment:

Our builds are fine, so there's no need for an issue on our side. The decision 
to release is based on the ecosystem catching up.

If you're able to help projects like setuptools, pip, and the core parts of the 
data science stack (which will need the most help) be able to support ARM64 
builds (despite the current lack of CI/CD support, which I'm working on 
separately), that will accelerate us being able to make the ARM64 releases 
available/supported.

[issue19124] os.execv executes in background on Windows

[Steve Dower]

Steve Dower  added the comment:

> emulating exec() is probably good enough for most cases, especially if code 
> expects to work in Windows.

I think good-enough emulation is fine, but we should update the docs to clarify 
that non-Unix platforms may create a subprocess with a new PID, and callers 
should avoid relying on POSIX semantics if they may run on non-compliant 
platforms.

> If Python implements its own system() and spawnv[e]() functions, support for 
> inheritable file descriptors [1] would probably have to be dropped

I don't see how its behaviour would change at all, unless we're going well out 
of our way to override the CRT. Which I wouldn't want to see us do.

So let's at least fix the current issue of having the child process break away 
immediately, by waiting for it and then exiting. Even if that's just swapping 
the execv call for spawnv(_P_WAIT) and then exiting, that's fine by me (all the 
CRT calls go through the same path, so they'll launch it consistently 
regardless of mode).

[issue19124] os.execv executes in background on Windows

[Eryk Sun]

Eryk Sun  added the comment:

> Even if that's just swapping the execv call for spawnv(_P_WAIT) 
> and then exiting, that's fine by me

Maybe call SuspendThread() on other threads, at least the ones that can be 
enumerated with the threading module.

> I don't see how its behaviour would change at all, unless we're going
> well out of our way to override the CRT. Which I wouldn't want to see 
> us do.

The suggestion was for Python to implement system() and spawnv[e]() using 
subprocess or _winapi. That would eliminate the problem of leaked handles when 
subprocess.Popen() is called concurrently with os.system() and os.spawn*(). 
However, inheritance of file descriptors cannot be reasonably implemented in 
that case, not without accessing private CRT data (i.e. the internal flags of 
each file descriptor). 

If os.spawn*() has to continue supporting inheritance of file descriptors, then 
the idea is probably a non-starter. All we can do is hope that the CRT's common 
spawn code will eventually use PROC_THREAD_ATTRIBUTE_HANDLE_LIST. This feature 
only protects against leaked handles (particularly important for pipes) if it's 
used by all concurrent CreateProcessW() calls that inherit handles.

[issue43671] segfault when using tkinter + pygame for ~5 minutes

[E. Paine]

E. Paine  added the comment:

Not sure why this was marked as a problem with tkinter (neither Pygame nor the 
example use it). I would be very surprised if this wasn't an issue with Pygame, 
as the Python is just requesting a dictionary deallocation which is then 
handled by Pygame's `font.cpython-39-darwin.so`.

My original script has tkinter used as well. I wasn't entirely sure where it

It does look now I've managed to investigate further to be something in pygame. 
I've never had to debug a segfault before.

[issue43674] strange effect at recursion limit

[TW]

New submission from TW :

user@development:~$ python3
Python 3.7.3 (default, Jan 22 2021, 20:04:44) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

def recurse(n):
print(n)
try:
recurse(n+1)
except RecursionError:
print("recursion error")
print(n)


Please note that there are 2 print(n) on the same level.

>>> recurse(0)
0
1
2
...
994
995
recursion error
994
993
...
2
1
0

Why is there no 2nd 995 after the recursion error?

Same happens for python 3.8.8 and 3.9.2.

Related question:

I also tried to set sys.setrecursionlimit(10) and ran recurse(0), but at a 
bit beyond 21800, it just segfaulted.

Is there a way to determine the practically working maximum it can do?

[issue39228] traceback.FrameSummary does not handle exceptions from `repr()`

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

__repr__() and repr() can raise exceptions. Silencing arbitrary exception is 
usually a bad idea. Even correctly raised code can raise exceptions such as 
MemoryError, RecursionError and KeybordInterrupt.

For this reason I think that the proposed change should not be made.
