2013-04-28upload-pack: ignore 'shallow' lines with unknown obj-idsLibravatar Michael Heemskerk1-2/+1
When the client sends a 'shallow' line for an object that the server does not have, the server currently dies with the error: "did not find object for shallow <obj-id>". The client may have truncated the history at the commit by fetching shallowly from a different server, or the commit may have been garbage collected by the server. In either case, this unknown commit is not relevant for calculating the pack that is to be sent and can be safely ignored, and it is not used when recomputing where the updated history of the client is cauterised. The documentation in technical/pack-protocol.txt has been updated to remove the restriction that "Clients MUST NOT mention an obj-id which it does not know exists on the server". This requirement is not realistic because clients cannot know whether an object has been garbage collected by the server.

2012-05-14pack-protocol: fix first-want separator in the examplesLibravatar Carlos Martín Nieto1-2/+2
When sending the "want" list, the capabilities list is separated from the obj-id by a SP instead of NUL as in the ref advertisement. The text is correct, but the examples wrongly show the separator as NUL. Fix the example so it uses SP.

2011-10-03pack-protocol: document "ERR" lineLibravatar Nguyen Thai Ngoc Duy1-0/+7
Since a807328 (connect.c: add a way for git-daemon to pass an error back to client), git client recognizes "ERR" line and prints a friendly message to user if an error happens at server side. Document this. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-11-13Update packfile transfer protocol documentationLibravatar Scott Chacon1-41/+494
The current technical documentation for the packfile protocol is both sparse and incorrect. This documents the fetch-pack/upload-pack and send-pack/ receive-pack protocols much more fully. Add documentation from Shawn's upcoming http-protocol docs that is shared by the packfile protocol. protocol-common.txt describes ABNF notation amendments, refname rules and the packet line format. Add documentation on the various capabilities supported by the upload-pack and receive-pack protocols. protocol-capabilities.txt describes multi-ack, thin-pack, side-band[-64k], shallow, no-progress, include-tag, ofs-delta, delete-refs and report-status.
