I've been using FileZilla for a while now for FTP stuff, and while it works great almost all of the time, there is one major flaw I've found:
If I upload a changed file, and a user of my site happens to do something that uses that file (much more common with include files) right at the moment it's uploading, the user gets a PHP error along the lines of unexpected $end
because the file is being read while it is half-uploaded.
Is there an option somewhere in FileZilla to lock a file while it is being uploaded, thus making the upload atomic, or am I out of luck and back to the search for a good FTP program?
