Irit Katriel  added the comment:

Since this is fixed in 3.6 and it’s too late for 3.5, I think this issue can be 
closed.

[issue44424] Decompress streaming bz2 file

[Carlos Franzreb]

New submission from Carlos Franzreb :

I am trying to lazily load items from a compressed file that resides in Zenodo. 
My goal is to iteratively yield the items without storing the file in my 
computer. My problem is that an EOFerror occurs right after the first non-empty 
line is read. How can I overcome this issue?

Here is my code:

import requests as req
import json
from bz2 import BZ2Decompressor


def lazy_load(file_url):
dec = BZ2Decompressor()
with req.get(file_url, stream=True) as res:
for chunk in res.iter_content(chunk_size=1024):
data = dec.decompress(chunk).decode('utf-8')
# do something with 'data'


if __name__ == "__main__":
creds = json.load(open('credentials.json'))
url = 'https://zenodo.org/api/records/'
id = '4617285'
filename = '10.Papers.nt.bz2'
res = req.get(f'{url}{id}', params={'access_token': 
creds['zenodo_token']})
for file in res.json()['files']:
if file['key'] == filename:
for item in lazy_load(file['links']['self']):
# do something with 'item'

The error I become is the following:

Traceback (most recent call last):
File ".\mag_loader.py", line 51, in 
  for item in lazy_load(file['links']['self']):
File ".\mag_loader.py", line 18, in lazy_load
  data = dec.decompress(chunk)
EOFError: End of stream already reache

To run the code you need a Zenodo access token, for which you need an account. 
Once you have logged in, you can create the token here: 
https://zenodo.org/account/settings/applications/tokens/new/

[issue44425] 'dirty' added to sys.version on Linux and Mac source builds depending on git version

[Mark Final]

New submission from Mark Final :

Hi,

We build Python 3.7 from source in-house for Windows, Linux and macOSX.

It's been noticed that 'dirty' has been appended to sys.version in our builds, 
even though the source tree has not been modified from a git clone. This only 
happens for Linux and macOSX.

I traced this to the following commands (which are unchanged in main):

https://github.com/python/cpython/blob/main/configure#L2833
https://github.com/python/cpython/blob/main/configure.ac#L50

> GITTAG="git --git-dir \$(srcdir)/.git describe --all --always --dirty"

I further traced it to behaviours of different versions of git. In particular, 
when git is invoked outside of the working tree, and --git-dir is used alone, 
'dirty' is always appended.

It's been noticed in a number of places online, including 
https://www.reddit.com/r/git/comments/4edtlx/git_describe_in_makefile_always_dirty/

Additionally using --work-tree does avoid the 'dirty' flag for a clean source 
tree, for git v2.21.0+.

I believe that this was this fix 
https://github.com/git/git/commit/a1e19004e11dcbc0ceebd92c425ceb1770e52d0b

However, since we do have usage of older versions of git, we've had to go with 
a different solution, which was to use git -C, i.e.

GITTAG="git -C \$(srcdir) describe --all --always --dirty"

so that git's working directory is changed to $(srcdir).

The other git commands in the code linked to do not seem to have the same 
issue, but we haven't changed them.

I'm writing this up in case anyone else has seen the issue, and offer the 
solution we found if it is useful.

Many thanks,
Mark

[issue39217] GC of a ctypes object causes application crash

[Irit Katriel]

Irit Katriel  added the comment:

As Terry suggested, it would be better to establish whether this is a python 
bug by asking on python-list, where more people are likely to see your question.

A complete script reproducing the crash is *always* better than a verbal 
description that we may or may not understand correctly.

Please reopen this or create a new issue if you are still seeing this issue on 
a recent (3.9+) version and you can provide a complete script that reproduces 
it.

[Rostislav Kondratenko]

Rostislav Kondratenko  added the comment:

Hello, I don't have that code, as I worked around that issue at the time.
I checked with my project, using PyObject_GC_New works fine.
It seems that since then the issue has been fixed at some point since 2017.
Either that or I misinterpreted what was going on back then.
I think we can safely close this issue.

[issue44426] Docs fail to build with Sphinx 4 due to Invalid C declaration

[Karolina Surma]

New submission from Karolina Surma :

Hello all,
I want to build Python 3.10~b2 documentation using Sphinx 4.0.2 (released in 
May 2021) as RPM in Fedora with aim to ship it in Fedora 35.

The build fails with the following error:

Warning, treated as error:
/builddir/build/BUILD/Python-3.10.0b2/Doc/c-api/complex.rst:49:Error in 
declarator or parameters
Error in declarator or parameters
Invalid C declaration: Expected identifier, got keyword: complex [error at 39]
  Py_complex _Py_c_neg(Py_complex complex)
  ---^
make: *** [Makefile:51: build] Error 2


The Sphinx changelog mentions in Bug fixes in 
https://www.sphinx-doc.org/en/master/changes.html#id21 the likely cause:
C, properly reject function declarations when a keyword is used as parameter 
name.

[issue44427] File extension for scripts on windows is unclear

[Malte Kliemann]

New submission from Malte Kliemann :

It is common practice to use no extension for python scripts on UNIX. In 
3.8.1.4., it is hinted that a script with a shebang line can be executed on 
windows only if the file extension of the script is associated with the python 
launcher.

I'm not sure where the right place is, but I suggest clearly stating that this 
is a critical requirement. As scripts on UNIX usually don't use file 
extensions, using these scripts without further modification is not possible 
cross-platform.

[issue40240] Expose public spelling of _PyGC_FINALIZED and _PyGC_SET_FINALIZED?

[STINNER Victor]

STINNER Victor  added the comment:

Pablo: "That is out of contract and goes against the guarantees on the GC and 
can (will) cause the finalizer of the object to be executed more than once. I 
don't think is a good idea to expose an API that allows breaking the guarantees 
that we give: every object is finalized once."

I concur with Pablo. We must not expose an API to "unfinalize" an object.

Irit Katriel: "Can this be closed now? It seems that the query API was added 
and the set API was rejected."

Right. I close the issue as rejected.

[issue44428] _ProactorBasePipeTransport.abort() after _ProactorBasePipeTransport.close() does not cancel writes

[Thomas Grainger]

New submission from Thomas Grainger :

demo program:

import asyncio
import socket
import threading

async def amain():
family = socket.AddressFamily.AF_INET
sock = socket.socket(family, socket.SOCK_STREAM)
sock.settimeout(1)
sock.bind(('localhost', 0))
sock.listen()
host, port = sock.getsockname()[:2]

event = threading.Event()

def serve():

with client:
client.recv(1)
event.wait()

t = threading.Thread(target=serve, daemon=True)
t.start()

reader, writer = await asyncio.open_connection(host=host, port=port)
try:
while True:

[issue44429] Tkinter Flow Geometry Manager

[Gary Davenport]

New submission from Gary Davenport :

Hi there.  I love Python and Tkinter.  I know that there are geometry managers 
pack, place, and grid.  I think there should be a flow type management 
available, like what is done in Java or html/css.  This is more important as 
responsive GUI design is needed with different screen sizes.

I initially addressed this by inheriting from the Frame in tkinter to a 
'FlowFrame' object and anything in that Frame would have flow geometry.

But this is a little awkward because the syntax is widget.pack() or 
widget.grid(), etc, so the method is linked to the widget.

So I altered the tkinter __init__.py  wrapper to add the .flow method so you 
can use widget.flow() syntax.

The flow geometry manager uses the grid managers methods.

The changes are straight-forward and I have 3 related projects on github:

1) https://github.com/garydavenport73/tkinterFlow - 
there are only 2 versions so history will demonstrate the relatively simple 
changes.

2) https://github.com/garydavenport73/FlowFrame -
a related project, FlowFrame object

3) https://github.com/garydavenport73/cpython
the formal changes to the most recent

https://github.com/python/cpython/blob/3.9/Lib/tkinter/__init__.py file.

[issue44430] [sqlite3] refactor threading tests

[Erlend E. Aasland]

New submission from Erlend E. Aasland :

The threading tests (ThreadTests) in Lib/sqlite3/test/dbapi.py has a lot of 
code duplication, and none of the test methods use the 
test.support.threading_helper.reap_threads helper. Also, some branches are not 
covered by this test class. Suggesting the following:

1. Rewrite ThreadTests with a _run_test() helper method that does the heavy 
lifting
2. Add test.support.threading_helper.reap_threads to _run_test()
3. Use _run_test() in all threading tests
4. Add test case for sqlite3.Connection.set_trace_callback
5. Add test case for sqlite3.Connection.create_collation

[issue43945] [Enum] standardize format() behavior

[Ethan Furman]

Ethan Furman  added the comment:

Thinking about this some more I am partially reversing course.  The idea behind 
`IntEnum` and `IntFlag` is to be, as close as possible, drop-in replacements 
for existing integer-based constants.  If the format() of those two change then 
they become much less attractive.

So it won't.  Instead, any user-mixed enumerations will get the new behavior:

class Grades(int, Enum):
A = 5
F = 0

will emit a DeprecationWarning now, and in 3.12 `format(Grades.A)` will product 
'A' instead of '5'.

[issue44429] Tkinter Flow Geometry Manager

[Zachary Ware]

Zachary Ware  added the comment:

Hi Gary.

This sounds interesting.  However, Tkinter generally tries to be a pretty thin 
wrapper around Tcl/Tk; is there something like this already in Tk that could be 
used instead, or existing discussion to add such to Tk?  We certainly would not 
want to wind up in the situation of conflicting with Tcl/Tk if they later add 
something in the same vein :)

Also, the ship has long sailed for adding this to 3.9; 3.11 is the earliest 
this could happen at this point; I've adjusted the issue metadata accordingly.

[issue44432] SourceFileLoader.load_module() is mixing content of previosly loaded files

[Andrew Johnson]

New submission from Andrew Johnson :

Hi,

I'm loading multiple files in same convention - same filename, as a part of 
creating a build system. I can compare the case to the loading multple 
configuration files for various plugins in the application, the file contents 
of multiple files from different directories are mixed together which looks 
dangerous.

Here is a reproducible case for Python 3.9.4 (running on Arch Linux)
