#44665 [NEW]: Memory leak in array_push operation
From: sasha at integrate dot ru
Operating system: Linux
PHP version: 5.2.5
PHP Bug Type: Arrays related
Bug description: Memory leak in array_push operation
Description:
Sorry for my english
php with curl, dbase, dom, gd2, mbstring,pgsql, simplexml,soap,sockets
It running under eAccelerator, but when I turn it off, the result is just
the same.
actually we use only pgsql. we get request (rather big - more than 3000
rows in result) making array of objects and then trying to convert each
object into html string. converted string (each about 2 Kb length) have
been pushed into array
very soon memory usage growing to 64 Mb and script is crushed
This problem is solved by method refact
protected function _refact($arr)
{
$myarr=array();
while(!empty($arr)) $myarr[]=array_shift($arr);
return ($myarr);
}
I call this function after 75, 150, 300 etc iterations, but calling this
function reduce performance. Is that behaviour (I mean memory usage
growing) normal?
Reproduce code:
---
Normal script (crushed)
http://ver.web.integrate.ru/test1.php
Cheated script (with refact method)
http://ver.web.integrate.ru/test1.php
Each script reports tht Init memory (Memory at the begin), how much
objects it proceeds (Now showing), iteration counter (Cicling iteration),
current memry usage (current memory usage) and length of string we pushed
into array (string_length).
Cheated script (in red hrs) show also the length of array we throw to
refact method
Expected result:
I guess that the memory usage won't grow while running this script because
the array of objects poped every turn, and the volume of each element of
this array more than the volume of elements of the result array
Actual result:

ORACLE_HOME should be available for _Apache_ process during the start
up process.
Oracle directory also has to be readable by Apache user.
