[issue35259] Py_FinalizeEx unconditionally exists in Py_LIMITED_API

[Martin Panter]

Martin Panter  added the comment:

I added the Py_FinalizeEx API in Issue 5319, but was relying on input from 
others about dealing with Py_LIMITED_API. After reading the documentation 
, I now see that the function 
would be considered part of the limited API because its documentation doesn’t 
say otherwise. So Arthur’s resolution is correct.

[issue34589] Py_Initialize() and Py_Main() should not enable C locale coercion

[STINNER Victor]

STINNER Victor  added the comment:

C locale coercion is just one parameter used to select the Python
filesystem enconding. There are many others which are read later during
Python initialization, and they are inter-dependent.

https://github.com/python/cpython/blob/7f4ba4afd47f21f61de9035544809fc67d136f35/Include/coreconfig.h#L69

I don't see which problem you are trying to solve here.

For me, PYTHONCOERCECLOCALE environment variable must be ignored when -I or
-E is used, for security reasons and to get more deterministic behavior. So
I am opposed to read/enable C locale coercion earlier.

That's also why PYTHONMALLOC only change the memory allocator late in the
Python initialisation, whereas it would be simpler to read/apply the option
earlier.

For the FreeBSD CURRENT bug, I recently modified Python to use ASCII if
"force ASCII" mode is enabled. I made this change for... HP-UX! On FreeBSD,
the filesystem encoding was already ASCII in practice (FreeBSD uses Latin1
but announes ASCII!?). I am not surprised to see bugs on specific
configuration with special option (disable UTF-8 mode) :-)

I am fixing Unicode bugs on weird cased before 3.0 and we are still not
done! Recently I fixed a bug in localeconv() when LC_MONETARY uses a
different encoding than LC_CTYPE... Such config sounds like a bad choice,
but well, it "works" on Python2...

[issue35309] Typo in urllib.request warning: cpath → cpath

New submission from Jakub Wilk :

It should be "capath", not "cpath", in this warning:

DeprecationWarning: cafile, cpath and cadefault are deprecated, use a custom

[issue34589] Py_Initialize() and Py_Main() should not enable C locale coercion

[Nick Coghlan]

Nick Coghlan  added the comment:

If I've understood https://bugs.python.org/issue35290 and its resolution in 
https://github.com/python/cpython/commit/f6e323ce322cf54b1a9e9252b13f93ebc28b5c24
 correctly, that's a concrete example of why I consider the early coercion 
approach that avoids any kind of redecoding dance significantly more robust 
against issues arising from future changes in the CPython startup sequence.

I'm away for AWS Re:Invent until Dec 2, but after I get back, I'll finally sit 
down and take one last pass over this to see if I can come up with a version 
that Victor is actually willing to review and approve.

[issue35308] webbrowser regression: BROWSER env var not respected

[Zhiming Wang]

New submission from Zhiming Wang :

This is a regression in Python 3.7:

$ BROWSER=w3m python3.6 -c 'import sys; import webbrowser; 
print(sys.version); print(webbrowser.get()); print(webbrowser._tryorder)'
3.6.7 (default, Nov 24 2018, 09:47:01)
[GCC 4.2.1 Compatible Apple LLVM 10.0.0 (clang-1000.11.45.5)]

['w3m', 'MacOSX', 'chrome', 'firefox', 'safari', 'w3m']

$ BROWSER=w3m python3.7 -c 'import sys; import webbrowser; 
print(sys.version); print(webbrowser.get()); print(webbrowser._tryorder)'
3.7.1 (default, Nov 24 2018, 09:35:18)
[Clang 10.0.0 (clang-1000.11.45.5)]

['MacOSX', 'chrome', 'firefox', 'safari', 'w3m', 'w3m']

Note how Python 3.7.1 webbrowser decides to choose MacOSX as the default 
although BROWSER is explicitly set to w3m. (The above code does not run on 
Python 3.7.0 due to bpo-31014).

This is because of misinterpretation of the `preferred` kwarg when bpo-31014 
was fixed. See 
https://github.com/python/cpython/commit/25b804a9c21c735ce322877f105ebab2539ccfc1#diff-546766353a40839aa72374ecca5b0925R566.
 Browsers in BROWSER should be registered as `preferred=True` instead.

[issue35307] Command line help example is missing "--prompt" option

[HolgerFrey]

New submission from HolgerFrey :

In the documentation of the command line options of the "vent" module, the 
option "--prompt" is missing:

Current text:
> [...]
> 
> The command, if run with -h, will show the available options:
> 
> usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear]
>  [--upgrade] [--without-pip]
>  ENV_DIR [ENV_DIR ...]
> 
> [...]

The prompt option is also missing in the rest of the example output

output of python3 -m venv -h:
> python3 -m venv -h
> usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear]
> [--upgrade] [--without-pip] [--prompt PROMPT]
> ENV_DIR [ENV_DIR ...]
> [...]

While I can see your point, I'm a little skeptical that anyone who's able to 
write C source code and compile it can't work out how to combine two binary 
files... :-)

[issue35301] python.exe crashes - lzma?

[Jonathan]

Jonathan  added the comment:

In total my python.exe process crashed 6 times with the exact same error, 
compressing about 60,000 pages, so about 1 in 10,000 failed.
However, I have ran the same process monthly for the last several months and it 
has never done that before despite processing mostly the same sites and 
compressing similar quantities of pages. The code is completely unchanged from 
last month.

Upon reflection, the only thing that has changed since then is that I am now 
running BOINC (https://boinc.berkeley.edu/) in the background on the machine. 
So I have just re-ran the entire process with BOINC suspended. Not a single 
crash!
It seems that somehow BOINC and Python are interacting to cause Python to crash.

[issue34160] ElementTree not preserving attribute order

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I am working on adding a canonization support (issue13611 for ElementTree and 
perhaps separate issue for minidom), but prefer to keep this issue open for the 
case if this task turns out to be too difficult.

Ned, what module is used in your tests for serialization? minidom or 
ElementTree?
