This means we can't receiving data until all the READ packets sent. is that ok?
No, that's not OK and we can't have it so. The best way (to get high transfer speeds) is to send as many READ packets as possible before we read anything, as on a fast network we might get read responses back once have saturated the outgoing "queue".
Why not send window adjust packet in _libssh2_channel_write() .
I think we should move out the window_adjust calling from within channel_read() to have it done more independently. Doing that would also remove the unexpected side effect that channel_read() will actually send data on the channel at times. If we did only this, sftp_read() would immediately get in a better shape as then the receive_window call won't destroy the outgoing packets like now.
