#27722 [NEW]: Better pointer check to avoid crashes

From: fjortiz at comunet dot es Operating system: any PHP version: 5.0.0RC1 PHP Bug Type: SOAP related Bug description: Better pointer check to avoid crashes Description: ------------ Hi, In my WSDL I defined a schema and forgot the attibute "targetNamespace". I know that's something you shoudn't forget, but, instead making Apache crash, wouldn't it be more robust to check for NULL pointers and send a gentle error? Fortunately I have a debug PHP5RC1 installed so I located the crash: php_schema.c line 1410 newType->namens = estrdup(ns->children->content); Sure it crashes, ns==NULL ... I guess it's the same problem for other retrieved elements/attributes. PHP-SOAP should be capable of trapping any unvalidated XML. If you are short of time I even offer myself to do some of that nasty pointer-check around. Thanks for your attention and your great efforts. -- Edit bug report at http://bugs.php.net/?id=27722&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27722&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27722&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27722&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27722&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27722&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27722&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27722&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27722&r=support Expected behavior: http://bugs.php.net/fix.php?id=27722&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27722&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27722&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27722&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27722&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27722&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27722&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27722&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27722&r=float
