- Thread-topic: обработка nginx-ом stderr полученного от fast cgi сервера
Работает связка nginx+php-fpm.(nginx 7.22, centos 5.2)
При получении от php-fpm сообщений в stderr(warnings¬ice) nginx не верно
обрабатывает их, поведение напоминает переполнение буфера для stderr.
Вот пример php скрипта который воспроизводит ошибку:
<?php
$array = array();
for ($i = 1; $i < 20; $i++)
{
if ( $array[$i] == 1) {
print "test\n";
}
}
print "done\n";
?>
При $i<20 работает как положено, в лог ошибок пишется:
2008/11/27 18:40:19 [error] 5656#0: *4218 FastCGI sent in stderr: "PHP Notice:
