#19050 [Fbk->Opn]: ftp_* functions vs. proftpd

ID: 19050 User updated by: darklord@revai.hu -Summary: Problems with fgets useing large buffers (about 65530) Reported By: darklord@revai.hu -Status: Feedback +Status: Open -Bug Type: Filesystem function related +Bug Type: FTP related -Operating System: Linux Debian Woody +Operating System: Linux Debian Woody (2.4.18) -PHP Version: 4.1.2 +PHP Version: 4.2.2 New Comment: It turned out to be ftp_* bug, sorry. So: To solve the error with ftp_get i've rewriten the code to use fopen with ftp:// filename. It's a workaround, not a FIX! To solve the error with ftp_nlist, i've used the code posted bellow (the one which retries the listing) I've no idea why has the buffer size change worked (65530->3000) but temporary it solved the problem (my first bug report), but then more calls were made to the reader function and the hanging began again. The proftpd developer team says that it's not their problem, I'll write them something nice ... And sorry for the misleading ... to all of you. Previous Comments: ------------------------------------------------------------------------ [2002-08-26 06:29:46] wez@php.net Is this a problem with fgets or is the problem with ftp_get? (there's a big difference!). Can you put these two lines before your fopen line: echo "Downloaded file from server\n"; flush(); ------------------------------------------------------------------------ [2002-08-26 04:02:54] darklord@revai.hu The -d 3 doesn't solve the problem with ftp_rawlist, but the following code works for it: $i=0; while (($a=ftp_rawlist($this->ftp_fd,$dir)) === false) { $i++; if ($i > 5) { die("Error"); } } ------------------------------------------------------------------------ [2002-08-26 03:33:35] darklord@revai.hu #13400 is a workaround for this bug, but I think proftp dev team should know about this thing ... ------------------------------------------------------------------------ [2002-08-26 03:28:38] darklord@revai.hu I think this error is specific to proftpd becouse the script works fine on a wu-ftpd ... ------------------------------------------------------------------------ [2002-08-26 02:13:07] darklord@revai.hu Hi! I've tryed php 4.2.2 (php-cvs don't compile, the error is in the mysql lib). Ok! The script above now prints the following (I've chaged the ftp timeout to 1 sec): Warning: ftp_get: in /home_real/darklord/devel/iwo/modules/host_access/ftp/base.php on line 144 I use proftpd and this bug is like #18781, but they say the functions are slow, but in my case the functions are hanging. I use a local server (my computer) so the transfer should be fast. (Sorry for the prev bug report ... but changing the buffer size solved the problem ... temporaly) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
