[JGIT PATCH 0/6] Add timeouts to network IO

From: Shawn O. Pearce <spearce@spearce.org>

If there's a bug in the remote peer software, or even just random network hardware/cable failures between us and the remote peer, we might block indefinitely waiting for more incoming data, or waiting for TCP ACKs necessary to release space in our transmit buffer.

This series adds a timeout to everything, allowing the caller to define some maximum waiting period before we abort and declare the remote peer to be unresponsive. The default timeout of 0 will use the traditional "block indefinitely" behavior we have always had.

Shawn O. Pearce (6):
  Create input and output streams that have timeouts
  Add remote.name.timeout to configure an IO timeout
  Add timeouts to smart transport protocol clients
  Add timeouts to smart transport protocol servers
  Add timeouts to anonymous git:// daemon
  Add --timeout command line options
