[issue5672] Implement a way to change the python process name
Marcelo Fernández marcelo.fidel.fernan...@gmail.com added the comment: So, while I'd be pleased to have it included in the stdlib, I'm not really convinced it would be useful to such a large audience. I think different, if python becomes even more successful to be used in desktop apps, this feature will be *very* important, because the reasons I've exposed in this thread.

Any possibility this module can be included in the regular python standard library, in the future? Only in the far future. I don't think the Python standard library should include a module whose version number is 0.2. I agree: I started the project 4-5 days ago and, albeit very limited in its scope, for portability reasons is way more complex than a simple syscall and needs to be tested on many other platforms. Of course, when I said future I meant when this project is stable and tested enough... :-) Thanks -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5672 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5672] Implement a way to change the python process name
Marcelo Fernández marcelo.fidel.fernan...@gmail.com added the comment: Great, piro! I'm taking a look at it, and it seems to use setproctitle() in BSD, and writes over the argv array in most Sys-V like systems; this includes Linux? My question is because I think there's a better and supported method for Linux, that is, using prctl [1]. I read somewhere that changing argv causes some inconsistencies between programs who read /sys files, /proc files... or I don't remember what, but it is, in fact, not the *recommended* way. Prctl is. :-) PR_SET_NAME and PR_GET_NAME parameters in prctl.h: [1] http://www.kernel.org/doc/man-pages/online/pages/man2/prctl.2.html Could this module be altered to use a prctl call in Linux (2.6.9)?

I read somewhere that changing argv causes some inconsistencies between programs who read /sys files, /proc files... or I don't remember what, but it is, in fact, not the *recommended* way. Prctl is. :-) This is interesting: do you have any reference? For example, take a look at the comments here: http://abock.org/2006/02/09/changing-process-name-in-mono It seems that some utilities and programs (killall, gnome-system-monitor, and so on) looks for the process name in /proc/PID/status, not in /proc/PID/cmdline, so it should be better (in Linux), to modify both, /proc/PID/cmdline (changing argv) *and* /proc/PID/status (calling prctl()). I installed py-setproctitle, and can't kill it with killall once I set the name to hello, for example. :-( [1]+ Detenidopython marc...@marcelo-laptop:~/src/py-setproctitle$ ps a PID TTY STAT TIME COMMAND 1030 tty4 Ss+0:00 /sbin/getty -8 38400 tty4 1033 tty5 Ss+0:00 /sbin/getty -8 38400 tty5 1049 tty2 Ss+0:00 /sbin/getty -8 38400 tty2 1050 tty3 Ss+0:00 /sbin/getty -8 38400 tty3 1052 tty6 Ss+0:00 /sbin/getty -8 38400 tty6 1349 tty7 Ss+ 17:14 /usr/bin/X :0 -br -verbose -auth /var/run/gdm/auth-for-gdm-XhETSO/database -nolisten tcp vt7 2225 tty1 Ss+0:00 /sbin/getty -8 38400 tty1 10344 pts/0Ss+0:00 /bin/bash -l 11923 pts/1Ss 0:00 bash 12068 pts/2Ss+0:00 bash 12485 pts/1T 0:00 hello 12496 pts/1R+ 0:00 ps a marc...@marcelo-laptop:~/src/py-setproctitle$ killall hello hello: proceso no encontrado Another example: The gnome-system-monitor still lists the 'hello' process (PID 12485) like 'python'. So we should try I've tested with the difference between clobbering argv and call prctl: two demo programs are in the tools directory of the module project [2]. For what I observed, clobbering argv changes what shown in ``/proc/PID/cmdline``, whereas prctl changes what can be read in ``/proc/PID/status`` (and ``stat`` too). ``ps`` uses the former, but switches to the latter when calling ``ps a`` and ``ps f``. ``top`` toggles between the two pressing ``c``. Sorry, but here (Ubuntu 9.10) it works the other way around: ps lists the /proc/PID/status - name field and ps a lists the /proc/PID/cmdline. But I got the explanation. :-) I think is probably better to have both strings updated: I'd prefer this behavior instead of the title being set in different places on different Linux versions. IMHO, I'd prefer both things: to change the argv array *and* calling prctl() if possible (Linux 2.6.9). If Linux is lower than 2.6.9, fallback to change argv only. Regards -- Marcelo F.

[issue3466] urllib2 should support HTTPS connections with client keys
Marcelo Fernández fernandez...@yahoo.com.ar added the comment: The workaround I posted before doesn't work with Python 2.6. This one works (at least) with Python 2.5 *and* Python 2.6: import httplib import urllib2 key_file = 'mykey.pem' cert_file = 'mycert-signed.pem' class HTTPSClientAuthConnection(httplib.HTTPSConnection): def __init__(self, host, timeout=None): httplib.HTTPSConnection.__init__(self, host, key_file=key_file, cert_file=cert_file) self.timeout = timeout # Only valid in Python 2.6 class HTTPSClientAuthHandler(urllib2.HTTPSHandler): def https_open(self, req): return self.do_open(HTTPSClientAuthConnection, req) This is a little class to use it: class Connection(object): def __init__(self, url): # TODO: Validate/Sanitize the url self.url = url self._cookiejar = cookielib.CookieJar() def send(self, **data): parameters = urllib.urlencode(data) opener = urllib2.build_opener(HTTPHandler(debuglevel=DEBUG_LEVEL), HTTPSClientAuthHandler(debuglevel=DEBUG_LEVEL), HTTPCookieProcessor(self._cookiejar)) req = Request(self.url, parameters) server_response = opener.open(req).read() print server_response return server_response Regards -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue3466 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5672] Implement a way to change the python process name
Marcelo Fernández fernandez...@yahoo.com.ar added the comment:
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/2S+ 0:00 | \_ ./python
5611 pts/3S+ 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/2S+ 0:00 | \_ hello_process_name
5635 pts/3S+ 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).

[issue5672] Implement a way to change the python process name
New submission from Marcelo Fernández fernandez...@yahoo.com.ar: As python gains more popularity, more and more applications run under CPython in a common user desktop. The problem is that if a user has 2 or more python apps running there is no way to identify them correctly from the generic Task/Process Manager Application (in Windows/Linux/OSX/any OS), because all appear as a python process. Take Ubuntu for an example. There are more cases when this is annoying: - Imagine two python process (doing different things, of course) sending messages to syslog: looks like all coming from python process. - A bash script which wants to killall one application: how can it identify a given python script between two or more python processes? There are some methods [1][2] to work around it, but there are not just Linux/BSD only, moreover, there are not included in the python standard modules. [1] http://davyd.livejournal.com/166352.html [2] http://code.google.com/p/procname/ I hope this issue gets considered in the community to fix it, I really think this is important... :-) Regards, Marcelo -- components: Extension Modules messages: 85252 nosy: marcelo_fernandez severity: normal status: open title: Implement a way to change the python process name type: feature request ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5672 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
