Masaya Suzuki	2d103c31c2	pack-protocol.txt: accept error packets in any context In the Git pack protocol definition, an error packet may appear only in a certain context. However, servers can face a runtime error (e.g. I/O error) at an arbitrary timing. This patch changes the protocol to allow an error packet to be sent instead of any packet. Without this protocol spec change, when a server cannot process a request, there's no way to tell that to a client. Since the server cannot produce a valid response, it would be forced to cut a connection without telling why. With this protocol spec change, the server can be more gentle in this situation. An old client may see these error packets as an unexpected packet, but this is not worse than having an unexpected EOF. Following this protocol spec change, the error packet handling code is moved to pkt-line.c. Implementation wise, this implementation uses pkt-line to communicate with a subprocess. Since this is not a part of Git protocol, it's possible that a packet that is not supposed to be an error packet is mistakenly parsed as an error packet. This error packet handling is enabled only for the Git pack protocol parsing code considering this.

Brandon Williams	ecc3e5342d	serve: introduce the server-option capability Introduce the "server-option" capability to protocol version 2. This enables future clients the ability to send server specific options in command requests when using protocol version 2.

Brandon Williams	72d0ea0056	ls-refs: introduce ls-refs server command Introduce the ls-refs server command. In protocol v2, the ls-refs command is used to request the ref advertisement from the server. Since it is a command which can be requested (as opposed to mandatory in v1), a client can sent a number of parameters in its request to limit the ref advertisement based on provided ref-prefixes.

Brandon Williams	ed10cb952d	serve: introduce git-serve Introduce git-serve, the base server for protocol version 2. Protocol version 2 is intended to be a replacement for Git's current wire protocol. The intention is that it will be a simpler, less wasteful protocol which can evolve over time. Protocol version 2 improves upon version 1 by eliminating the initial ref advertisement. In its place a server will export a list of capabilities and commands which it supports in a capability advertisement. A client can then request that a particular command be executed by providing a number of capabilities and command specific parameters. At the completion of a command, a client can request that another command be executed or can terminate the connection by sending a flush packet.
