From: mikeb at xamo dot com Operating system: FreeBSD 4.8 PHP version: 5.0.2 PHP Bug Type: cURL related Bug description: Curl curl_getinfo()
Description: ------------ When requesting the CURLINFO_CONTENT_TYPE using curl_getinfo(), if there is an error (such as connection error) or missing header for any reason, running the function using specifically curl_getinfo($fd,CURLINFO_CONTENT_TYPE) will cause a PHP core dump. The problem seems to be that the function does not check for the instance of the Content-Type: header before it tries to parse it. Temporary workaround is simply not using the function, and parsing for the data yourself. Reproduce code: --------------- <? $ch=curl_init(); curl_setopt($ch,CURLOPT_URL,"http://sell.yahoo.com/";); curl_setopt($ch,CURLOPT_HEADER,1); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); $contents=curl_exec($ch); // the following line will cause a core dump // as sell.yahoo.com does not return an appropriate Content-Type header. Also happens on connect errors. $content_type=curl_getinfo($ch,CURLINFO_CONTENT_TYPE); curl_close($ch); ?> Expected result: ---------------- Should return content-type in the HTTP Header (if it exists, or false/empty string if it doesnt exist) Actual result: -------------- PHP Core Dump. -- Edit bug report at http://bugs.php.net/?id=30475&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30475&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30475&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30475&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30475&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30475&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30475&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30475&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30475&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30475&r=support Expected behavior: http://bugs.php.net/fix.php?id=30475&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30475&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30475&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30475&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30475&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30475&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30475&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30475&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30475&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30475&r=mysqlcfg
