#48203 [Asn]: crash when CURLOPT_STDERR is set to regular file

ID: 48203 Updated by: jani@php.net Reported By: php-bug at paulsohier dot nl Status: Assigned Bug Type: cURL related Operating System: * PHP Version: 5.*, 6CVS (2009-05-09) Assigned To: jani New Comment: This fixes all the test cases I could come up with: http://pecl.php.net/~jani/patches/bug48203.patch Even the quite insane ones too. It falls back to using STDERR which is the default anyway if the file pointer is closed prematurely. Previous Comments: ------------------------------------------------------------------------ [2009-05-26 06:09:24] jani@php.net It's also the bad implementation for CURLOPT_STDERR which causes such problems. It should be handled using the debugging facilities in cURL. ------------------------------------------------------------------------ [2009-05-10 16:27:48] jani@php.net It's about the order in which stuff is freed/destroyed. Common problem with some other extensions as well. ------------------------------------------------------------------------ [2009-05-09 21:35:15] php-bug at paulsohier dot nl We just tried it with some more different hosts, and it happens at at least google.nl and nu.nl as well. Also, adding the curl_close() to the end fixs the problem. But should php's GC not do the same call internally? ------------------------------------------------------------------------ [2009-05-09 21:30:58] jani@php.net Mark: CURLOPT_STDERR Pass a FILE * as parameter. Tell libcurl to use this stream instead of stderr when showing the progress meter and displaying CURLOPT_VERBOSE data. ------------------------------------------------------------------------ [2009-05-09 21:30:12] jani@php.net Adding this as last line also fixes the problem (ie. reset to default..) curl_setopt($ch, CURLOPT_STDERR, STDERR); I don't know why the other hosts work and other don't. Propably there's some traffic / error and the file handle gets destroyed or otherwise mangled during shutdown and curl then tries to use it.. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
