Review request for KDE Frameworks and David Faure.


Changes
-------

Addressed Mark's suggestions.


Repository: kio


Description
-------

So far, we used to just read whenever some data was required. This works on sequential devices because the data is already available. This is not the case when we have a sequential device, such as a socket, where data arrives when it arrives. This will also prove useful on non-sequential devices as well when we want to keep reading in case new data appears.

This patch takes the AsyncDataEnabled setting on accordinly by:

* only reading from the device when readyRead is available.
* finishes the transfer whenever the device is closed.

Testing
-------

Tests still pass, new test also passes.

The test is using lambdas to delay write. I don't think it's available.
Can I add some kind of #if HAS_LAMBDA and make the test depend on it?
I don't think adding slots and make the buffer an attribute would be very nice... I can also sub-class the buffer.


Thanks,

Aleix Pol Gonzalez
