Edit report at https://bugs.php.net/bug.php?id=63411&edit=1 ID: 63411 Comment by: aa dot vasilenko at gmail dot com Reported by: marcel at silverstreet dot com Summary: curl_multi_select() returns invalid value Status: Assigned Type: Bug Package: cURL related Operating System: CentOS 6.3 PHP Version: 5.3.18 Assigned To: pierrick Block user comment: N Private report: N New Comment: This bug breaks existing libs, like Buzz https://github.com/kriswallsmith/Buzz , that relies on curl_multi_* functions. This is how I came here. Previous Comments: ------------------------------------------------------------------------ [2012-11-03 03:42:09] pierrick@php.net I'm not sure we really want to wait 1 second for nothing in this specific case. Furthermore, as mentioned in my commit message, when libcurl returns -1 in max_fd after calling curl_multi_fdset, it is because libcurl currently does something that isn't possible for your application to monitor with a socket and unfortunately you can then not know exactly when the current action is completed using select(). I would personally keep the current behaviour. ------------------------------------------------------------------------ [2012-11-02 04:52:57] reeze@php.net This is related to this see: https://github.com/php/php-src/commit/2e8ab65270e7d1ebe1ef0dfe13836c29d72c7010 http://curl.haxx.se/libcurl/c/curl_multi_fdset.html There is no handles in the test script, it is expected after the patch. ------------------------------------------------------------------------ [2012-11-01 18:33:41] aa dot vasilenko at gmail dot com Confirming the same bug. PHP 5.4.8, CentOS 5.8 ------------------------------------------------------------------------ [2012-11-01 11:10:46] marcel at silverstreet dot com Description: ------------ curl_multi_select() seems broken in PHP 5.3.18 on CentOS 6.3. The behavior of the test script below is different than it used to be, returning immediately without select with a -1 (failure) return value. Test script: --------------- $mh = curl_multi_init(); print curl_multi_select($mh, 1.0); curl_multi_close($mh); Expected result: ---------------- curl_multi_select() should take 1.0 seconds to complete and returns 0 Actual result: -------------- curl_multi_select() returns immediately with return value of -1 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63411&edit=1
