Description:
------------
Yesterday I tried the newest PHP 5.1 snapshot on my SunONE webserver (I
am the maintainer of the NSAPI SAPI code). This webserver is
multithreaded so your new WSDL caching code in ext/soap should work
great. But it doesn't.
The first call to a php script that uses SoapClient works correct
(everytime). Further requests to the same script crash the webserver
with SIGSERV, SIGBUS, SIGILL (illegal instruction!!!).
Because of the SIGILL I suspect that the caching code overwrites some
executale code.
The problem is that it happens at totally different locations, most
times there is not even a core dump available that can be analyzed
(stack is corrupt so no dump availabe). When I disable soap.wsdl-cache
completely, everything works again without any crash. I have seen that
with the new code no longer /tmp/wsdl-XXXXX files are generated. Is
there a possibility to switch
to the older file-based caching code? For eaxample as enumeration in
the wsdl-cache php.ini configuration option? Is there any other
possibility to disable the wsdl cache code without undoing a lot of
soap patches? I want to update the webserver because of security
reasons to latest snapshot.
Do you have similar problems with other webservers that are
multithreaded? Sorry that I cannot give more helpful information (the
crashes are totally different and the corefiles are mostly useless).
Reproduce code:
---------------
The first time after restart this code works without problems. Later
calls (when using the cashed WSDL) mostly crash:
$ws=new
SoapClient('http://ws.pangaea.de/ws/services/PangaVista?wsdl',array('encoding'=>'ISO-8859-1'));
$ua=isset($_SERVER['HTTP_USER_AGENT'])?$_SERVER['HTTP_USER_AGENT']:'nobrowser/0.0';
$sess=$ws->registerSession($this->session,$ua,$_SERVER['REMOTE_HOST'],"PangaVista");
$search=new stdClass();
$search->queryString='grobe';
$res=$ws->advSearch($sess,$search,$this->offset,$this->count,'thumb');
print_r($res);
Expected result:
----------------
No crash :)
Actual result:
--------------
