A crash, for the tracker, is failed execution without a Python exception and

Debian, Fedora, Gentoo, RHEL, and Ubuntu (AMD64) buildbots are currently green. 
 We don't have one for SUSE, open or other wise.

If you have not yet reported the issue to openSUSE, I would do so in case this 
is something they should deal with.

[issue34063] binhex REASONABLY_LARGE = 32768 so what is 128000

[Jim Jewett]

New submission from Jim Jewett :

binhex defines a module-wide constant of 

REASONABLY_LARGE = 32768  # Minimal amount we pass the rle-coder

Later on, in 5 locations it does either ifp.read(128000) or 
ifp.read_rsrc(128000)

It isn't clear why a different constant is used, let alone why a literal is 
used instead of something like REASONABLY_LARGE.

[issue34057] Py_Initialize aborts when using static Python version. Windows

[Alberto]

Alberto  added the comment:

Hey Victor,

I've spent another number of hours debugging the problem and trying to avoid 
encodings to be loaded but I've had no luck since initfsencoding is necesary 
for init_sys_streams to work and that's an important function that sets stdin, 
stout and sterr. 

It seems that encodings is the only thing that prevents Py_Initialize to be 
called and therefore for a static python version to be used.

Is there any way to move encodings to pythoncore? Is there any other solution? 
I'm happy to put my time on this (I've already spent 3 full days debugging the 
problem).

I think this could be considered a bug since there is no point on statically 
build python and use it as a library as the README stands if there is still 
requirements on encodings which need to reside on the filesystem. 

Thank you again for your time

[issue34062] Python launcher on Windows does not work with --list or --list-paths

[Eryk Sun]

Eryk Sun  added the comment:

I don't think the launcher has unit tests.

The if statement in process() that calls show_python_list only checks for "-0". 
It needs to check for the long names as well, e.g.:

if (argc == 2) {
/* First check for -0[p], --list, or --list-paths. */
if (!wcsncmp(p, L"-0", 2) || !wcscmp(p, L"--list") ||
!wcscmp(p, L"--list-paths")) {
valid = show_python_list(argv);
}
}

show_python_list shouldn't need to be modified. It already looks for -0p and 
--list-paths to include paths in the output format.

[issue34059] multiprocessing deadlock

[Guillaume Perrault-Archambault]

Guillaume Perrault-Archambault  added the comment:

A friend of mine has suggested a fix that seems to work for now (upgrade numpy 
from 1.14.3 to 1.14.5). This makes no sense at all but it does seem to work for 
now. I have a strong suspicion that this is just masking the problem and that 
it will reappear.

However, since it works I would not want you to waste any time on this. I will 
reopen if the deadlock reappears!

I do apologize if you already spent a lot of time on this.

Regards,
Guillaume

[issue34059] multiprocessing deadlock

[Guillaume Perrault-Archambault]

Guillaume Perrault-Archambault  added the comment:

Hi Victor and Yang,

Thanks for your fast replies.

I did initially think it could be a torch issue. Indeed, I have an
equivalent numpy testcase that does not deadlock. However, the fact that it
gets stuck inside a multiprocessing wait statement makes me think it's
still a multiprocessing issue.

I've spent two weeks full time on this issue. Over at torch forums I've had
no replies (
https://discuss.pytorch.org/t/multiprocessing-code-works-using-numpy-but-deadlocked-using-pytorch/20473
).

On stackexchange I only got a workaround suggestion that works sporadically
(
https://stackoverflow.com/questions/51093970/multiprocessing-code-works-using-numpy-but-deadlocked-using-pytorch).
Basically I can get rid of the deadlock (sometimes) if I impose only one
thread per process. But this is not a solution anyway.

I have tried stepping through the code, but because it is multiprocessed,
you cannot step through it (at least not in the conventional way, since the
main thread is not doing the heavy lifting).

I've tried adding print statements in the multiprocess library and mucking
around with it a bit, but debugging multi-processed code in this way is an
absolute nightmare because you can't even trust the order in which print
statements display on the screen. And probably more relevant, I'm out of my
league here.

I'm really at a complete dead end. I'm blocked and my work cannot progress
without fixing this issue. I'd be very grateful if you could try to
reproduce and rule out the multiprocessing library. If you need help
reproducing I can send a different testcase that deadlocked on my friend's
Mac (for him, the original testcase did not deadlock).

Testcase I attached in my original post it sometimes deadlocks and
sometimes doesn't, depending on the machine I run on. So I'm not suprised
you got no deadlock when you tried to reproduce.

I can always get it deadlocking on Linux/Mac though, by tweaking the code.

To give you a sense of how unreliably it deadlocks, just removing the for
loop in the code (which is outside the multiprocessing portion of the
code!) somehow gets rid of the deadlock. Also, it never deadlocks on
Windows.

If you could provide any help on this issue I'd be very grateful.

Regards,
Guillaume.

[issue34061] Document sqlite3.NotSupportedError exception

[Berker Peksag]

New submission from Berker Peksag :

Most of the exceptions in sqlite3 module were documented in issue 6057 
(https://github.com/python/cpython/commit/ed789f9cf9586d94e85115bb516a2ab6b9a2f668)

Unfortunately, I noticed that I missed NotSupportedError while reviewing PR 
8086. I think it should be documented in the Exceptions section as well:

https://docs.python.org/3.8/library/sqlite3.html#exceptions

We can adapt the text in PEP 249:

Hi,

First of all thank you for your answer.
If every module can't be statically compiled within a library, what is the

Can I modify the code to make it completely statically?

Thank you

I think there are open tickets discussing this, and the problem is more complex 
that a simple PR:

- Debian does multiarch that’s more than just lib/lib64
- some systems have lib32 I think
- recent systems merge / and /usr, is that relevant?
- how does virtualenv follow or customize install schemes

I'm not sure what you mean by "what you often do". I'll push a fix to master 
and 3.7 branches in a few minutes, so perhaps you can open a PR to ask Linux 
vendors to add a patch for 3.7.0 to their packages.  An easier solution would 
be for you to disable refcounting tests that rely on gettotalrefcount just for 
3.7.0.  And I apologize for the hassle :(

[issue34059] multiprocessing deadlock

[STINNER Victor]

STINNER Victor  added the comment:

IMHO it's an issue with your usage of the torch module which is not part of the 
Python stdlib, so I suggest to close this issue as "third party" or "not a bug".

I'm can't reproduce the deadlock, maybe it's related to torch package? Can you 
try without torch to see if this happens again?

Agree. a) who will separate its functionality into separate module for PyPI, b) 
who start a thread on python-devel?

[issue23493] optimize sort_keys in json module by using operator.itemgetter()

[INADA Naoki]

INADA Naoki  added the comment:

I can't confirm significant performance benefit.
sort_keys is not bottleneck of pure Python encoder.

BTW, benefit from C encoder is more significant.  It's about 3x faster.
Adding `indent` option support to C encoder may be good target for new 
contributors who want to write C.

[issue34042] Reference loss for local classes

[Kay Hayen]

Kay Hayen  added the comment:

Hello,

so it's harmless and it explains the other reference counting issue, where a 
change in call convention could make a reference counting bug show or go away:

codecs.open(TESTFN, encoding='cp949')
This was showing it, where as
codecs.open(TESTFN, "rb", 'cp949')

was not. With all the difference being a dictionary passed into a function call 
or not. I am now assuming that getting your fix this will also go away. Caused 
me a bit of head scratching already.

If you could do what you often you, and make this what distributions like 
Debian pull from, it would be good enough in terms of release for me, as it 
blocks Nuitka tests from passing on them.

Yours,
Kay

[issue34007] test_gdb fails in s390x SLES buildbots

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

All the builds fail consistently after 
http://buildbot.python.org/all/#/builders/54/builds/465 and things were passing 
before 465. Maybe is this something to do with the commit that happened there 
that we could revert and test it in the machine by doing a git-bisect? But I 
couldn't see anything on GDB related code being changed in Python on #465. My 
initial hunch was that it had something to do with GDB 8.0+ but Ubuntu 18.04 
LTS also runs on 8.0+ fine.

[issue34057] Py_Initialize aborts when using static Python version. Windows

[STINNER Victor]

STINNER Victor  added the comment:

> Why is Python looking for external modules when it is a statically linked 
> library and encodings should be built-in?

Hi, this is not a bug. Python needs its standard library. You might want to put 
the whole stdlib into a single ZIP, but I don't recall how to do that.

The encodings and codecs modules are not built-in, but _codecs is built-in:

>>> import encodings, codecs, _codecs
>>> encodings

>>> codecs

>>> _codecs


I suggest to close this issue as "not a bug". You should ask on a Python 
mailing list or forum to get help how to build a standalone Python.

[issue16822] execv (et al.) should invoke atexit handlers before executing new code

[Tal Einat]

Tal Einat  added the comment:

> we could definitely have a separate "atexec" handler

Couldn't coverage.py and similar apps can just invoke the atexit handlers 
before calling os.execv() or similar?  If so, perhaps a mention of this in the 
docs would suffice?

[issue34047] IDLE: on macOS, scroll slider 'sticks' at bottom of file

[Tal Einat]

Tal Einat  added the comment:

Confirmed on latest master on OSX.

I'm also experiencing many other kinds of erratic scrolling behavior:
1. Dragging the scrollbar isn't possible immediately after opening the file 
Lib/idlelib/editor.py.  Also later after scrolling to the top.
2. Scrolling via two-finger swipte on the trackpad scrolls down both when I 
scroll up and down.
3. Clicking in the trough slightly below the slider has no effect.

There's definitely something very broken!

Commenting out the `return 'break'` in handle_yview() doesn't appear to affect 
this.

In all cases I ran idle from a terminal via `python -m idlelib` and saw no 
errors.
