Re: How to rename on complete

[David Latorre <dv...@gmail.com>]

Hello,

 I would say sebb's answer is the easiest way to go.

 If this is not a solution for you,   there are several possible solutions:

- You can implement your own version of "STOR/STOU" commands and  invoke
the rename there. Done this, it works but I prefer sebb's solution.

- You can develop a "Filesystem" implementation which locks files. Never
tried this, but should work.

- Don't lock or rename files, just change the 'client' which is reading the
incomplete files.  We integrate different channels, not only FTP,  so we
always do this.  Whenever we find a new file we store the size and
timestamp and we wait for some time to check if the file has been changed.
When we detect that the file isn't being changed anymore, we process it.


Would that be enough for you ?
