[Python-Dev] Advice / RTFM needed for tool setup to participate in python development from a Windows host

[pjfarley3]

Hello,

I hope this is the correct place to ask this question.  I have a desire to
participate in python development in a particular area from my Windows host
machine, but I am not finding any concise listing of the tool setup needed
to fully participate, nor any detailed guidance on how to proceed when
underlying code debugging is necessary.

I do know that some version of the MS VS20xx suite is necessary to begin.
My initial attempts using the VS2019 Community Edition have been less than
successful when it comes to debugging an underlying C library component when
the starting program is python because I have not figured out how to use the
VS2019 environment to do that.

So I would appreciate any RTFM / URL that can guide me in starting to
participate, especially for guidance on debugging procedures for underlying
C components when the initial program is a python script.

I have read most of the "Python Developers Guide" material, but there is not
any Window-specific tooling information that I have seen there yet.  What
other tooling do I need besides a VS20xx environment?

I do have good experience in C programming, but not much in using VS20xx
IDE's.

TIA for your gentle guidance in curing my ignorance.

Peter

Yes, that is my specific issue.  I have a C DLL invoked by a python wrapper 
module using ctypes that has at least one issue (and likely more than one) so I 
need to be able to start a python test script and debug the lower-level DLL 
code.  The C test programs for the lower-level C DLL all seen to succeed, so I 
am suspecting something is wrong in the wrapper code.

If anyone has or knows of step-by-step instructions on how to set that debug 
environment up and start the outer-level script with debug breakpoints in the 
DLL I would greatly appreciate it.  I'm also doing my own searches for 
tutorials on debugging python with VS20xx, but have not read/viewed one of 
those yet.

I have in fact been able to re-compile cpython and the lower-level DLL using 
the VS2019 command line tools, but so far my only debugging capability has been 
to insert fprintf's to a trace file in the lower-level DLL code (or macros that 
result in such output) into the C code where I *think* the problem is 
happening, but I have not been able to nail it down yet.  Being able to start 
the process from the IDE and catch any C errors when they happen would be ideal.

My environment is Win10-64 and python 3.8.5.

[pjfarley3]

Thank you Emily!  That may allow me to do what I need to do to find the 
error(s) lurking there.

 

No multi-processing is involved in my current project, so it should be more 
straightforward to accomplish the debugging I need to do.

Even if Python itself is the standard distribution, you should be able to debug 
your outside DLL module in VS just by putting a breakpoint on your favorite 
line and setting "/path/to/python.exe -m yourmodule" as the command path under 
debugging in your project properties, or whatever commandline accomplishes 
whatever initialization you need to test. Multiprocessing might be something 
else entirely, I don't know, I've only debugged DLLs in-process. As soon as 
your breakpoint is hit, it'll stop as you'd expect, even though you started 
something else entirely.

[pjfarley3]

Thanks for that link Steve.  I will read it and see what it can help me do.  It 
does seem like it is pretty much on target for the scenario I have, which is a 
C DLL project that is invoked by python wrapper functions invoked from a python 
script.

[Python-Dev] How to attract developer attention to issue tracker items?

[pjfarley3]

Hi developers,

What should / shouldn't I do to attract any python developer response to
issue tracker items?  I am unsure of the proper procedure to follow so I am
asking here first.

I have filed two issues on the python issue tracker for python curses
issues:

1.  # 43715, a documentation update request (suggested additional
documentation file uploaded)
2.  # 43716, a possible ABI issue for the curses.pair_number() function
return value in a Windows environment

With respect to the documentation issue, I would appreciate any review of
whether the suggested documentation addition that I uploaded as a text file
is acceptable as-is or whether further refinement or correction is needed.

In the case of the possible ABI issue I am uncertain whether the issue is in
the python interface code or in the underlying curses implementation library
(windows-curses V2.2.0 using PDCurses).  I would appreciate it if anyone
knowledgeable of the python curses interfacing code could advise me whether
I need to pursue the issue with the third party library provider or with the
python development team.  At the moment all that I know is that the
"workaround" that I discovered corrects the issue under Windows but is not
necessary under linux / ncurses (in my testing I used Ubuntu 20.04 WSL2 to
confirm that fact).

TIA for your patience with my ignorance of the proper procedures and
channels.

My environment:

Windows 10 Pro 64 (latest version)
Python 3.8.9 (tags/v3.8.9:a743f81, Apr  6 2021, 14:02:34) [MSC v.1928 64 bit
(AMD64)]
Windows-curses V2.2.0

What you're doing here is probably your best bet. Unfortunately the lack of 
response might stem from no core devs being interested in curses (but if any 
are then hopefully this email will spark their interest).

[Python-Dev] Question for potential python development contributions on Windows

[pjfarley3]

The Python Developers Guide specifically states to get VS2017 for developing
or enhancing python on a Windows system.

 

Is it still correct to specifically use VS2017 , or is VS2019 also
acceptable?

 

I ask this because I know that the *.vcproj files and other
build-environment files have changed format pretty dramatically over the
many releases of VS.  If a potential new contribution targeted for current
and future python will require new build environment files, I wouldn't want
to have to "down release" those files (or expect core dev's to do it) at or
after submission to the community for approval.  Much better to use the same
setup as core dev's use than to introduce up-level differences in the build
environment.

 

IOW, for new releases on Windows are core dev's still using VS2017 and so
potential contributors should also use that version, or has the core dev's
process for Windows releases been updated to use VS2019?

Thank you Łukasz, I was hoping that would be the answer.

How does one verify whether the C++ tools are 14.x, or is that just the usual 
for recent versions of VS2019?
