#39448 [NEW]: Maximum execution time exceeded even if is unlimited

[jschwabik at koop dot cz]

From: jschwabik at koop dot cz
Operating system: CentOS release 4.3
PHP version: 5.2.0
PHP Bug Type: Performance problem
Bug description: Maximum execution time exceeded even if is unlimited

Description:
------------
I've got script running from linux shell and sometimes it crashes with
"Maximum execution time of 30 seconds exceeded in some line" error in the
script.

The command on which it crashes is unpredictable. The script is runnig
sometimes 10 minutes, sometimes 30 minutes and crashes on different lines.
(It never runs 30 seconds).

I am running it from command line (CLI) (max_execution_time should be 0)
an I set it with set_time_limit(0) to 0.

I've tried two servers 4 php versions (4.4.2, 4.4.4,5.1.6,5.2.0)

In my php.ini is max_execution_time set to 0.

Sometimes it ends on ifx_fetch_row().
Sometimes it ends on mktime().

My configure
'./configure' '--with-config-file-path=/etc/php.ini'
'--with-apache=../apache_1.3.37/' '--with-informix=/opt/informix'
'--with-mysql=/usr/local/mysql/' '--enable-ftp' '--with-gd'
'--enable-gd-native-ttf' '--enable-gd-imgstrttf' '--with-zlib'
'--with-jpeg-dir=/usr/' '--with-freetype-dir=/usr' '--with-dom=./ext'
'--with-ldap' '--with-mssql=/usr/local/' '--enable-dbase'
'--with-iconv=/usr/local'


PHP Core Info
..
..
..
max_execution_time => 0 => 30
max_input_time => -1 => 60
open_basedir => no value => no value
output_buffering => 0 => no value
output_handler => no value => no value
post_max_size => 8M => 8M
precision => 12 => 12
safe_mode => Off => Off
..
..

Reproduce code:
---------------
<?
set_time_limit(0);

//connection to MYsql database
//connection to Informix database

//running Informix query (10 queries)


//doing some transformations and inserting into MYsql database (multiple
insert every 100 rows)

echo "End";


?>




Expected result:
----------------
"End" is echoed or some meaningful error message.

Actual result:
--------------
Fatal error:Maximum execution time of 30 seconds exceeded in ...

Perhaps this has to do with the problem in Bug #39361, where ini
settings which are valid for a directory only are still active when
leaving the directory (although ini_get() returns the correct value).

I tested some settings and they worked, so I though this problem is a
mbstring problem - but it possibly occurs also with other ini
settings...

I'm using IIS, MySQL, and PHP 5.1.1. This problem starting happening
randomly within the code, and there doesn't seem to be a reason for it
other then it seems to be related to MySQL calls... but I haven't
taken the time yet to test that theory. Its also is random which makes
it VERY hard to create a reproducable version.

I'll be upgrading PHP and MySQL tonight and will then spend some time
building a test case to reproduce this problem as its becoming more
frequent as of late.
