I started copying a 200MiB file from my desktop machine onto the Samba share. While that was copying, I got onto the server and tried to copy the file to /tmp and it happily did that for me without any indication that it was still being written to (which is was by the way.) So, that's not a good way of dealing with this. I think I'm going to have to go with a time delay function here ... -- There are potential problems using timing delays, and networking compounds them. It might be more robust to use some simple method outside of php to indicate a file is busy being copied, like using a reserved extension for the copy and then renaming to the proper filename after the copy is complete, or copying to a temp directory and then moving the file to the destination directory once copied (renames and moves take milliseconds). Assuming you're able to automate the copy process. Cheers Arno -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
