Edit report at http://bugs.php.net/bug.php?id=53241&edit=1 ID: 53241 Updated by: cataphract@php.net Reported by: Alexander dot Farber at gmail dot com Summary: fopen(..., 'xb') and CURLOPT_FILE make cURL fail with: fopencookie failed -Status: Assigned +Status: Closed Type: Bug Package: Streams related Operating System: CentOS 5.5 Linux PHP Version: Irrelevant Assigned To: cataphract Block user comment: N New Comment: Made the sanitizing function not exported. See rev #305108. Closing. Previous Comments: ------------------------------------------------------------------------ [2010-11-05 11:55:58] pajoye@php.net Is it really necessary to export php_stream_rep_nonstand_mode? If an extension uses it now it will be then compatible only with 5.3.4 or later, which is bad (remeber the 5.2.6+ pain). We also have some mode checks already in the stream implemenation, maybe it could be cleaner to use this function there as well. About the implementation of php_stream_rep_nonstand_mode, it should be stricter, not assuming that anything else is 'c' or 'x', we had bugs related to bogus mode in the past. ------------------------------------------------------------------------ [2010-11-05 02:33:42] cataphract@php.net Fixed for PHP 5.3 and trunk. Thank you for your report. ------------------------------------------------------------------------ [2010-11-05 02:29:10] cataphract@php.net Automatic comment from SVN on behalf of cataphract Revision: http://svn.php.net/viewvc/?view=revision&amp;revision=305095 Log: - Fixed bug #53241 (stream casting that relies on fdopen/fopencookie fails with streams opened with, inter alia, the 'xb' mode). ------------------------------------------------------------------------ [2010-11-04 19:55:42] cataphract@php.net The problem is the cast to a FILE* pointer fails when the modes "x"/"c" and variants are used. I'll see what can be done. ------------------------------------------------------------------------ [2010-11-04 14:36:39] Alexander dot Farber at gmail dot com Description: ------------ If I call: $fh = fopen('/tmp/yahoo.html', 'xb'); $ch = curl_init('http://www.yahoo.com/'); curl_setopt($ch, CURLOPT_FILE, $fh); then the last line will fail with the misleading fopencookie-message. I need to use 'xb' and not 'wb', to ensure that just 1 script instance writes into that file - please see more info here: http://stackoverflow.com/questions/4096470/php-curl-curl-setopt-fopencookie-failed Test script: --------------- <?php #phpinfo(); $fh = fopen('/tmp/yahoo.html', 'xb'); if ($fh) { $ch = curl_init('http://www.yahoo.com/'); curl_setopt($ch, CURLOPT_FILE, $fh); # XXX the line 6 curl_setopt($ch, CURLOPT_HEADER, FALSE); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); #curl_setopt($ch, CURLOPT_COOKIEJAR, '/dev/null'); #curl_setopt($ch, CURLOPT_COOKIEFILE, '/dev/null'); #curl_setopt($ch, CURLOPT_COOKIEJAR, '/tmp/cookies.txt'); #curl_setopt($ch, CURLOPT_COOKIEFILE, '/tmp/cookies.txt'); curl_exec($ch); if(!curl_errno($ch)) { $info = curl_getinfo($ch); echo 'Took '.$info['total_time'] . 's to send a request to '.$info['url']; } curl_close($ch); fclose($fh); } else { echo 'Can not open /tmp/yahoo.html'; } ?> Expected result: ---------------- I expect the script create the file /tmp/yahoo.html on the 1st run and put the downloaded content into it. Actual result: -------------- Nov 4 12:55:19 centos httpd: PHP Fatal error: curl_setopt() [<a href='function.curl-setopt'>function.curl-setopt</a>]: fopencookie failed in /var/www/html/proxy3.php on line 6 And the file is sero-sized: afarber@centos:html> ls -alZ /tmp/yahoo.html -rw-r--r-- apache apache user_u:object_r:httpd_tmp_t /tmp/yahoo.html ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53241&edit=1
