Re: [asterisk-users] Asterisk AMI - Create a daemon (background process)
PHP has had memory leak issues in the past, though modern versions are apparently much better. The thing is, when you write a daemon you must EXPECT it to exit at some point, maybe the socket went away or the system restarted or you are out of memory, whatever. You need to make sure you handle these situations regardless of which language you write in. Using inittab is one way, daemon-tools is another. For me, PHP with its C-like syntax, decent string handling, Perl Regex, and POSIX process control (including fork), it is good enough for most stuff that I do. -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Steve Edwards Sent: Tuesday, February 26, 2013 11:12 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Asterisk AMI - Create a daemon (background process) On Tue, 26 Feb 2013, Paul Belanger wrote: You don't want to use PHP for your daemon, change to another scripting language (EG: python).

Perl is always the correct language to use :D (In case anyone mistakes the above for a serious remark, it hardly matters what scripting language you use as long as it has an AGI library. PHP has outgrown powering web pages and is now a fully-fledged scripting language. Use whatever you feel comfortable with and if you don't feel comfortable with it, use something else; or at least, abstract out the scariest parts. You don't get prizes depending on the language you use, at least not in the parts of the real world I've lived in.) -- AJS Answers come *after* questions. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Since C is my sharpest tool, the question is somewhat moot :) Once you get past the overhead of parsing a scripting language like PHP or Python, I think the efficiency advantage of C is minimal and the actual execution time will be dominated by whatever the daemon is 'talking to' -- i.e. Asterisk or MySQL or ... For smaller, frequently executed programs, C will be at home enjoying a cold one with friends and family before scripting programs get out of the starting gate. -- Thanks in advance, - Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
