This patch (to python 2.7 trunk) allows to call prctl() function from
Linux kernel to change the process name. It adds two methods to the os
module: os.getprocname() and os.setprocname().
Working example:
marc...@marcelo-laptop:~/src/pytrunk$ ./python
Python 2.7a0 (trunk:71261M, Apr 5 2009, 16:32:55)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
[34831 refs]
>>> os.getprocname()
'./python'
[34833 refs]
>>> os.getpid()
5601
[34833 refs]
>>> os.setprocname('hello_process_name')
[34833 refs]
>>> os.getprocname()
'hello_process_name'
[34833 refs]
Before changing the process name:
marc...@marcelo-laptop:~/src/pytrunk$ ps -fax | grep 5601
Warning: bad ps syntax, perhaps a bogus '-'? See
http://procps.sf.net/faq.html
5601 pts/2 S+ 0:00 | \_ ./python
5611 pts/3 S+ 0:00 \_ grep 5601
After changing the process name:
marc...@marcelo-laptop:~/src/pytrunk$ ps -fax | grep 5601
Warning: bad ps syntax, perhaps a bogus '-'? See
http://procps.sf.net/faq.html
5601 pts/2 S+ 0:00 | \_ hello_process_name
5635 pts/3 S+ 0:00 \_ grep 5601
And "killall hello_process_name" works, Gnome Process monitor shows it
fine too. By now this is Linux only, but I hope to implement it also for
BSD (FreeBSD has it[1], OpenBSD [2] and NetBSD [3] too).
