ID: 49295 Updated by: srina...@php.net Reported By: frase at cs dot wisc dot edu Status: Assigned Bug Type: OpenSSL related Operating System: Win 2000 Pro SP4 PHP Version: 5.2.11RC1 Assigned To: srinatar New Comment:
ok, i was looking into this issue today. the issue is that , especially on windows -where sockets are not file descriptors unlike in unix, async sockets and openssl works together only if we use BIO wrappers provided by openssl module instead of directly accessing underlying sockets as file descriptors. the possible right way to do this would be to use to socket wrappers provided by SSL module (known as BIO wrappers which makes it work properly on windows). this will require some amount of fiddling our openssl module. i don't think, 5.2 is a good place to do this change. for now, commenting this below code should help you to run your script properly on windows. stream_set_blocking($socket, 0); i will spend more time on this and investigate on the best way to use BIO wrappers within existing openssl module say within php 5.3 Previous Comments: ------------------------------------------------------------------------ [2009-08-21 15:05:47] frase at cs dot wisc dot edu I had a chance to compile and test PHP5.2.11RC1 under Linux this morning (Ubuntu Jaunty, Apache 2.2.11 from repositories), and these warnings do not appear, however I noticed another problem. Although the SSL+async connection is successful and data is returned under Linux, the socket is not actually opened asynchonously. The script blocks until the socket has finished opening, exactly as it does without the ASYNC flag. This is also true under Windows, for the first run -- after that, of course, it returns the errors posted above. ------------------------------------------------------------------------ [2009-08-21 01:15:44] srina...@php.net this issue seems to be happening when this script is executed more than once and also seems to be happening only on windows. ------------------------------------------------------------------------ [2009-08-19 13:52:18] frase at cs dot wisc dot edu Description: ------------ stream_socket_client() can only open one socket using SSL and the STREAM_CLIENT_ASYNC_CONNECT flag, and then fails every time until the Apache process is restarted. SSL sockets without ASYNC open fine, as do plain TCP sockets with or without ASYNC. Originally reported as an update to bug #48182, which also only affected the combination of SSL+ASYNC, but now reported separately here per srina...@php.net's request. Additionally, the timeout (argument #4 to stream_socket_client()) is not ignored when using ASYNC, contrary to the manual: if set to 0 here, the first warning is "SSL: connection timeout" instead of "SSL: The operation completed successfully."
