Re: [PHP-SOAP-DEV] some benchmarks.

[Andrey H. <ahr...@ic...>]

Maybe I've some good news for you. Last night I do some hacking on the test
scripts.
Testing with ab a simple hello_world_client+server.php gives me 377 errors -
probably all of those are because of the segfault.
I started to debug in th userspace to realize where it is crashing - and
what a surprise, after I started to debug the scripts do not crash.
Here I will post 2 pairs of sample scripts. The first one gives errors, the
second one not. To be almost completely sure I have done throughout test for
the latter pair for 1,500,000 reqs or 25200 secs(7hours) - it did 1,386,142
requests. The difference between then is the server part of the pair. No
segfaulting scripts have just 2 lines more and these lines have nothing in
common with the SOAP extension.
hello_world_client.php + hello_world_server.php:
<?php
error_reporting(E_ALL);
echo microtime()."<br>\n";
$hello = new SoapObject("http://192.168.1.140/hello_world_server.php",
"urn:HelloWord");
echo microtime()."<br>\n";
echo $hello->hello_soap("alala");
echo microtime()."<br>\n";
//var_dump($hello);
//var_dump(get_class_methods('SoapServer'));
?>
hello_world_server.php
<?php
/*
$fname = 'tests/dbg'.str_replace(" ","_",microtime()).'.xml';
$fd=fopen($fname,'w+');

ob_start();
//var_dump($HTTP_RAW_POST_DATA);
//$a=ob_get_contents();
ob_end_clean();

fputs($fd,$a."\n");
fclose($fd);
*/
$server = new SoapServer("urn:HelloWord");
/*
$fd=fopen($fname,'a+');
fputs($fd,"after_server_create\n");
fclose($fd);
*/
$server->addfunction("hello_soap");

//$fd=fopen($fname,'a');
//fputs($fd,"after_addfunction\n");
//fclose($fd);

$server->handle();

function hello_soap($message){
 return "PHP-SOAP says ($message)";
}
?>
NOT SEGFAULTING pair:
<?php
error_reporting(E_ALL);
echo microtime()."<br>\n";
$hello = new SoapObject("http://192.168.1.140/hello_world_server_noseg.php",
"urn:HelloWord");
echo microtime()."<br>\n";
echo $hello->hello_soap("alala");
echo microtime()."<br>\n";
//var_dump($hello);
//var_dump(get_class_methods('SoapServer'));
?>
<?php
/*
$fname = 'tests/dbg'.str_replace(" ","_",microtime()).'.xml';
$fd=fopen($fname,'w+');
*/
ob_start();
//var_dump($HTTP_RAW_POST_DATA);
//$a=ob_get_contents();
ob_end_clean();
/*
fputs($fd,$a."\n");
fclose($fd);
*/
$server = new SoapServer("urn:HelloWord");
/*
$fd=fopen($fname,'a+');
fputs($fd,"after_server_create\n");
fclose($fd);
*/
$server->addfunction("hello_soap");

//$fd=fopen($fname,'a');
//fputs($fd,"after_addfunction\n");
//fclose($fd);

$server->handle();

function hello_soap($message){
 return "PHP-SOAP says ($message)";
}
?>

I hope that this will give some light what is going on.

Have a nice day
