Dan Stromberg added the comment: Isn't this "python script doesn't show up in top correctly" issue a matter of "#!/usr/bin/env python3"? If you "#!/usr/bin/python3" (for example) instead, top seems happy. -- nosy: +strombrg ___ Python tracker

Floris Bruynooghe added the comment: There are actually a few implementations on pypi, just search for prctl. At least one of them is pretty decent IIRC but I can't remember which one I looked at in detail before. Anyway, they would certainly be a reasonable starting point for python inclusion

Daniele Varrazzo added the comment: Hello everybody, I've finished porting the module to Python 3, so I think it's a good starting point for considering its inclusion into the stdlib. The source is already out; tomorrow I'll test for regressions on mac osx and release the package. I'm not go

Daniele Varrazzo added the comment: setproctitle is quite stable, my company uses it in production environment very heavily with python 2.x. Probably its users base is not huge, but that's because it's a relatively specialized tool. Python3 porting is not straightforward because python2 expor

Martin v. Löwis added the comment: Please don't provide a wrapper around ptrctrl. Instead, expose prctl as is (similar to how ioctl and fcntl get wrapped). It's ok to make some convenience adjustments (e.g. allowing fewer parameters than the actual call), and it's also ok to filter by option (fo

Marcelo Fernández added the comment: Great, it's my first patch to python and I'm very happy with your comments. :-) Thanks Amaury, do you think is better that I should take out getprocname() if setprocname() changes sys.argv too? When I got some spare time, I'll take a look at your suggestion

Amaury Forgeot d'Arc added the comment: Some remarks about the patch: 1 - this line causes a buffer overrun: strncpy(argv[0], name , strlen(name)); A possible solution is to do like posix_putenv(): have a static PyString that holds the memory, and just change the pointer argv[0]: argv[0]
