PHP cli Bellek kullanımı optimizasyonu

1 Cevap php

I am trying to code a custom url_rewriter for squid. & also with using some other url_rewriter programs like squidGuard so have to use a wrapper to able use both or any other program.

when i try to loop with php. (that's the way how squid communicates with external programs. STDIN/STDOUT. it gives you a url & you have to send the new one or old one back. )

it has a devastating memory usage even doing nothing. i've changed to wrap it with another bash script it is only a few lines. & it loops instead of php. calls php externally. when php script is done with the url returns it & exits. this way is much more better than instead of to loop the php script.

in php script nearly there is nothing now. (coz i'm still developing it.) it's only replacing video.yahoo.com to youtube.com. and a few variable and an explode() to parse input string that's all... but script is still using huge amount of memory

Burada PHP script

#!/opt/lampp/bin/php -q 
<php
ini_set('html_errors',false);
ini_set('implicit_flush',true);
ini_set('max_execution_time',0);
ini_set('register_argc_argv',true);

$nl="\n"; $tab="\t";
$ds=DIRECTORY_SEPARATOR;
$lamppdir='/opt/lampp/';
$htdocsdir='/opt/lampp/htdocs/';
$wdir='/opt/lampp/htdocs/bin/';
$incdir=$htdocsdir.'inc/';
$logfile=$wdir.'log.txt';

if ($argc>1){
    $return=$argv[1];
    $return=explode(' ',trim($return));
    $url=$return[0];
    $sourceip=$return[1];
    $user=$return[2];
    $method=$return[3];
    $urlgroup=$return[4];
    $myip=$return[5];
    $myport=$return[6];

    $logdata=$argv[1];

    // if(strlen($logdata)>50){ file_put_contents($logfile,$logdata.$nl,FILE_APPEND); }

    fwrite(STDOUT,$return[0]."\r\n");
}

exit(0);

Ve burada bash script

#!/bin/bash
 lamppdir=/opt/lampp/
 phpexecpath=/opt/lampp/bin/php
 phpredirectorpath=/opt/lampp/htdocs/bin/redir.php
 logdfile=/opt/lampp/htdocs/bin/log.txt
 forcedexit=false

 while [ "${forcedexit}" != "true" ]
 do
    read squidinput
    phpout=`"${phpexecpath}" "${phpredirectorpath}" "${squidinput}"`
    echo "${phpout}"
 done

 echo "\r\n"

exit 0

i zaten PHP cli hakkında yararlı belgeleri bulmak için googled & kaynak kullanım ama hayır şans.

Kaynak kullanımını azaltmak için herhangi bir tavsiye var mı?

i bu gülecek eminim. i yanlış yerde bakıyordu.

after a long tracing stdin/stdout of squid. i've just added an if statement in the loop. to control string's length as a url. 

while [ "${forcedexit}" != "true" ]
do
    read squidinput
    if [ -n squidinput ]
       then
    	phpout=`"${phpexecpath}" "${phpredirectorpath}" "${squidinput}"`
    	echo "${phpout}"
    fi
done

result: there is no waiting php processes in background anymore. because it's handling & exiting just in milliseconds.

without the IF statement squid is sending empty spaces and newlines to script so it never stops. i was trimming input string with php that is why i couldn't get earlier squid's weird stdins. trimming $argv is just an habit brought. squid version was 2.6stable7 probably it's all the same in earlier versions. i've just lost half a day :( thank you for everyone read.
