ID: 29479 Comment by: jerj at coplanar dot net Reported By: black at scene-si dot org Status: Suspended Bug Type: Feature/Change Request Operating System: linux PHP Version: 6CVS New Comment:
It appears someone has implemented this: http://cvs.sourceforge.net/viewcvs.py/wikipedia/extensions/pecl-proctitle/ I'm going to try and compile it now. Previous Comments: ------------------------------------------------------------------------ [2006-02-18 10:39:35] dan812 at hotmail dot com This would be a very nice feature. Using perl you can change $0 variable. PHP do lack this functionality. ---From perlvar doc----- $0 Contains the name of the program being executed. On some (read: not all) operating systems assigning to $0 modifies the argument area that the "ps" program sees. On some platforms you may have to use special "ps" options or a different "ps" to see the changes. Modifying the $0 is more useful as a way of indicating the current program state than it is for hiding the program you're running. (Mnemonic: same as sh and ksh.) Note that there are platform specific limitations on the the maximum length of $0. In the most extreme case it may be limited to the space occupied by the original $0. In some platforms there may be arbitrary amount of padding, for example space characters, after the modified name as shown by "ps". In some platforms this padding may extend all the way to the original length of the argument area, no matter what you do (this is the case for example with Linux 2.2). Note for BSD users: setting $0 does not completely remove "perl" from the ps(1) output. For example, setting $0 to "foobar" may result in "perl: foobar (perl)" (whether both the "perl: " prefix and the " (perl)" suffix are shown depends on your exact BSD variant and version). This is an operating system feature, Perl cannot help it. In multithreaded scripts Perl coordinates the threads so that any thread may modify its copy of the $0 and the change becomes visible to ps(1) (assuming the operating system plays along). Note that the the view of $0 the other threads have will not change since they have their own copies of it. --------------------------- Regards.

How about a work-around? ------------------------------------------------------------------------ [2004-08-01 13:25:48] [EMAIL PROTECTED] setproctitle() is only implemented on BSD; other systems that emulate this use a non-portable dangerous hack that makes certain assumptions about how the process will be run. Suspending until this situation changes. ------------------------------------------------------------------------ [2004-08-01 10:43:06] black at scene-si dot org Description: ------------ With linux it is sometimes useful to be able to change the process name (by identifying a process in the system error logs or for debugging for example).. The c(++) or the perl way doesnt work in php as far as i tried, and so i pressume that it is not possible itself. You can consult yourself with http://lightconsulting.com/~thalakan/process-title-notes.html - an extensive example of how the title should be changed Reproduce code: --------------- $argv[0] = "progname-debugval"; Expected result: ---------------- I expect that the programs process title would be changed by modifying $argv[0], or by introducing a new function which would change the process title respectively. Actual result: -------------- The process name in `ps` output of the respective program should change accordingly to the change of $argv[0]; ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29479&edit=1
