Tk Library Source Code

The put and get methods currently read from a file or
in-memory string, or write to a file or a variable.
Both methods should support reading from and writing to
a channel too.

Both should also be able to give up ownership of such a
channel so that it can be driven by someone else
instead of only from the inside of the ftp module.

Enclosed a test script for the new functionality. Requires 
the ftp example "ftpd.test", to be submitted as part of the 
implementation of this FR.

Enclosed a patch implementing the feature. Exception: 
Giving up ownership is not implemented. This would require 
a complete reworking of how the ftp package operates. It is 
a big sync. statemachine and cannot give up ownership of a 
channel because this requires jumping out of the SM. IOW, 
we would have rewrite the thing to be completely async.

It might be possible to achieve a similar effect by using 
special in-memory channels, for example fifo2.
