Bug #63795 [Asn]: url-7.28.1 breaks PHP curl_getinfo and curl_multi_getcontent

Edit report at https://bugs.php.net/bug.php?id=63795&edit=1 ID: 63795 Updated by: pierrick@php.net Reported by: blueness at gentoo dot org Summary: url-7.28.1 breaks PHP curl_getinfo and curl_multi_getcontent Status: Assigned Type: Bug Package: cURL related Operating System: Linux PHP Version: 5.4.9 Assigned To: pierrick Block user comment: N Private report: N New Comment: This bug was introduced when the support of the value 1 for CURLOPT_SSL_VERIFYHOST was removed in 7.28.1. In your code sample, you're using curl_setopt_array. How this function work internally is that it will loop over all your options and set them one by one on your curl handle using the libcurl curl_easy_setopt function. If one of this set fail, the function will break the iteration and will return false. In your case, when you're using libcurl 7.28.1, curl_setopt_array will fail when it will try to set CURLOPT_SSL_VERIFYHOST to 1, and then will not set CURLOPT_HEADER. The result of your curl_exec function will then not include the headers. Then when you remove the begining of your string to remove your header, you're in fact removing the begining of your content since there is no header included in the original string. If you move your CURLOPT_SSL_VERIFYHOST to the end of your array this should fix your problem. Can you confirm ? I started a discussion on internal to see how we want to deal with this problem.

See the following downstream bugs for more details: https://sourceforge.net/p/curl/bugs/1172/ https://bugs.gentoo.org/show_bug.cgi?id=444788 In the gentoo bug, please look at comment #14 since it pin points the curl commit that deprecated CURLOPT_SSL_VERIFYHOST=1 and led to the breakage in php. Test script: --------------- <?php $cm = curl_multi_init(); $stuffs = curl_init(); $curl_options = array( CURLOPT_URL => 'http://www.google.ca', CURLOPT_RETURNTRANSFER => 1, CURLOPT_SSL_VERIFYHOST => 0, // these are the problem CURLOPT_SSL_VERIFYPEER => 0, // toggle 0/1 to test CURLOPT_HEADER => 1 ); curl_setopt_array($stuffs, $curl_options); curl_multi_add_handle($cm, $stuffs); do { curl_multi_exec($cm, $running); } while($running > 0); $content = curl_multi_getcontent($stuffs); $info = curl_getinfo($stuffs); curl_multi_remove_handle($cm, $stuffs); curl_multi_close($cm); print_r($info); // cuts off too much, the header size is incorrect echo mb_substr($content, $info['header_size']); ?> Expected result: ---------------- For the expected and actual results, please see https://bugs.gentoo.org/show_bug.cgi?id=444788 comments #10-13 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63795&edit=1
