Seems to have been introduce in r262454. ------------------------------------------------------------------------ [2011-12-21 15:03:29] roberto at spadim dot com dot br maybe the array parameters isn´t being removed from memory? i tryed to change code inserting a comma after timeout parameter "'timeout'=>1," and it add more memory leak per interaction more commas = more memory leak $context= stream_context_create(array('http'=>array('timeout'=>1,,,,,))); ------------------------------------------------------------------------ [2011-12-20 05:20:49] roberto at spadim dot com dot br Description: ------------ hi, when i create a context inside a function i see a memory leak, but when i create it in the main source code line, i don´t see it... please check the script.. i think the problem is something that don´t leave memory get back when destroying context variable Test script: --------------- memory leak: <?php function g(){ $context=stream_context_create(array('http'=>array('timeout'=>1))); $ret=file_get_contents('http://172.17.0.5/not_found',0,$context); unset($context); return($ret); } $base=memory_get_usage(); while(1){ g(); usleep(50000); echo (memory_get_usage()-$base)."\n"; // memory get bigger and bigger here.... } ?> memory leak too: <?php $base=memory_get_usage(); while(1){ $context= stream_context_create(array('http'=>array('timeout'=>1))); $ret=file_get_contents('http://172.17.0.5/not_found',0,$context); usleep(50000);unset($ret,$context); echo (memory_get_usage()-$base)."\n"; // memory get bigger and bigger... } ?> nice: <?php $base=memory_get_usage(); $context= stream_context_create(array('http'=>array('timeout'=>1))); while(1){ $ret=file_get_contents('http://172.17.0.5/not_found',0,$context); usleep(50000);unset($ret); echo (memory_get_usage()-$base)."\n"; // memory is nice here... } ?> Expected result: ---------------- NICE: Warning... 3552 Warning... 3552 Warning... 3552 Warning... 3552 Warning... 3552 Warning... 3552 MEMORY LEAK: Warning... 40120 Warning... 41344 Warning... 42568 Warning... 43792 Actual result: -------------- well i think that others fields explain... MEMORY LEAK: Warning... 40120 Warning... 41344 Warning... (+- 1224 per while interaction) i don´t know how to solve this, unset don´t work, =null don´t work, and i don´t find a function to destroy contexts... ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60570&edit=1
