Bug #15836 Updated: Bug #11162 pfsockopen closes connection after script finishes !
ID: 15836 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: Documentation problem Operating System: FreeBSD PHP Version: 4.1.1 New Comment: I think this locate the problem and try to test it as soon as possible. http://marc.theaimsgroup.com/?l=php-dev&m=100842297427750&w=2 [2000-09-27 22:17:24] [EMAIL PROTECTED] A UNIX socket connection is made using pfsockopen(). On the initial script entry, a message is sent to our server and the reply is correctly received by the script. On subsequent script entries, messages to the server are still sent successfully, but upon attempting to reply a SIGPIPE is received by server, and the php script receives a 0-length reply to its fgets() read. We traced the problem to ext/standard/file.c, in the routine _file_socket_dtor(). In that routine, the macro SOCK_FCLOSE is used, which calls php_sock_close() in fsock.c. This routine correctly handles the persistent socket. However, after that call, _file_socket_dtor() then incorrectly calls the C routine shutdown(), which is what caused the problem. In fact, php_sock_close() already completely takes care of the shutdown() (for the non-persistent case), so in any event the shutdown() call in _file_socket_dtor() is not necessary.

But in any case p* functions should not close this connection, but hold it opened in hashed table for next time, same script will be executed on this apache process, isnt it ? Unfortunately this doen not happend ;( PHP really closes the socket right after script end ;( And in tests apache was configured like: MinSpareServers 1 MaxSpareServers 1 StartServers 1 MaxClients 1 That means that only 2 apache processes are in memory, (parent and a child) and only one of them handles php scripts. But all tests faied, as i talk. any pfsockopen connections are closed after end of script ;( [2002-03-02 13:44:13] [EMAIL PROTECTED] [EMAIL PROTECTED] 29-Jan-2001 03:26 OK, WRT to the p* functions opening a new connection when one already exists. It is my understanting that (under Apache anyways) this is on a per-process basis. If you do a 'ps auxw|grep httpd' on your server you will see more than one process. What p* does is make a p-connection on one of those processes only, the one that actually handles your request. Chances are that when you hit the page again it will be answered by a different process. I'm guessing if you keep hitting reload you'll get around to the original process again and there will be no error message or second connection open. Anyhow, this is true of all p* functions; they open not one connection per server, but one connection per server _process_. Hope this explains something (it's from the manual at http://www.php.net/manual/en/function.pfsockopen.php) I'm keeping this open as a doc problem though, cause the documentation is very skimmy.

Closing. [2001-11-21 12:03:03] [EMAIL PROTECTED] Can try with latest RC and see if the problem still exists http://www.php.net/~zeev/php-4.1.0RC3.tar.gz Feedback. [2001-05-29 01:18:39] [EMAIL PROTECTED] When using pfsockopen() it closes the connection as soon as the script finishes. According to the manual, the connection should remain open. I have had a few people write their own script to test this on their machine to make sure it wasn't my machine, or my code, and both of them also produced the same result. So I beleive this is either a bug with pfsockopen() or with the online documents. -- Edit this bug report at http://bugs.php.net/?id=11162&edit=1
