Bug #14052 Updated: ftp_rawlist: Hangs up

ID: 14052 Comment by: kofaldt@basic-vision.com Old Reported By: msjackson@bluemail.ch Reported By: kofaldt@basic-vision.com Status: Open Bug Type: FTP related Operating System: Win2K PHP Version: 4.1.1 New Comment: I had the same problem with linux and PHP 4.1.1. In my opinion there's a problem in line 886 of file ext/ftp/ftp.c. I replaced memmove(ftp->inbuf, ftp->inbuf+4, FTP_BUFSIZE-4); with memmove(ftp->inbuf, ftp->inbuf+4, FTP_BUFSIZE-4); if (ftp->extra) ftp->extra -= 4; The execution of memmove drops 4 bytes of the last response text which is stored in ftp->inbuf. In case of ftp->extra != NULL, there are extra characters and 4 characters of the next response are lost if you don't adjust ftp->extra.

It just won't interprete the script anymore for a second there it allmost seems as if it needs to flush or waits for a timeout to occur. ------------------------------------------------------------------------ [2002-01-09 11:32:45] yohgaki@php.net Please update version :) ------------------------------------------------------------------------ [2002-01-09 11:31:38] mfischer@php.net I'm setting this to open, version to 4.1.1. Although in CVS there exists now a way to adjust the timeout (ftp_set_option(FTP_TIMEOUT_SEC, 10); for example) it's not a solution and there are still some flaws in the implementation IMO. ------------------------------------------------------------------------ [2002-01-09 11:06:06] msjackson@bluemail.ch Yes I've tested it with 4.1.1 and the problem ist still present. 90 Seconds is absolutly true! In this time he hangs in the ftp_rawlist function... and then he will continue, but often doesn't work the next call to ftp_rawlist too. And sorry, it isn't a problem of the user, but when executing per CLI, the script run more reliable than executed by apache. When I start the script directly it run sometimes until end (Not often). I tested it on 2 machines (W2K-Notebook and W2K-PC). I'm very intrested in this function, because i'm working on a little web-filesharing-tool, which should index content of ftps. Thanks for your feedback! ------------------------------------------------------------------------ [2002-01-02 09:46:20] mfischer@php.net Is this bug still present to you, also with 4.1.0? If so, can you verify that the 'hang' time is about 90 seconds (its a fixed coded timeout value in ext/ftp)? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
