2018-05-30Merge branch 'jt/partial-clone-proto-v2'Libravatar Junio C Hamano1-0/+9
Transfer protocol v2 learned to support the partial clone. * jt/partial-clone-proto-v2: {fetch,upload}-pack: support filter in protocol v2 upload-pack: read config when serving protocol v2 upload-pack: fix error message typo
2018-05-06{fetch,upload}-pack: support filter in protocol v2Libravatar Jonathan Tan1-0/+9
The fetch-pack/upload-pack protocol v2 was developed independently of the filter parameter (used in partial fetches), thus it did not include support for it. Add support for the filter parameter. Like in the legacy protocol, the server advertises and supports "filter" only if uploadpack.allowfilter is configured. Like in the legacy protocol, the client continues with a warning if "--filter" is specified, but the server does not advertise it.

2018-04-24serve: introduce the server-option capabilityLibravatar Brandon Williams1-0/+10
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. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-03-15fetch-pack: support shallow requestsLibravatar Brandon Williams1-7/+11
Enable shallow clones and deepen requests using protocol version 2 if the server 'fetch' command supports the 'shallow' feature. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-03-15fetch-pack: perform a fetch using v2Libravatar Brandon Williams1-1/+66
When communicating with a v2 server, perform a fetch by requesting the 'fetch' command. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-03-15ls-refs: introduce ls-refs server commandLibravatar Brandon Williams1-0/+31
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.

2018-03-15serve: introduce git-serveLibravatar Brandon Williams1-0/+170
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.
