The git-update-server-info command prepares informational files
to help clients discover the contents of a repository, and pull
from it via a dumb transport protocols. Currently, the
following files are produced.
- The $repo/info/refs file lists the name of heads and tags
available in the $repo/refs/ directory, along with their
SHA1. This can be used by git-ls-remote command running on
the client side.
- The $repo/info/rev-cache file describes the commit ancestry
reachable from references in the $repo/refs/ directory. This
file is in an append-only binary format to make the server
side friendly to rsync mirroring scheme, and can be read by
git-show-rev-cache command.
- The $repo/objects/info/pack file lists the name of the packs
available, the interdependencies among them, and the head
commits and tags contained in them. Along with the other two
files, this is designed to help clients to make smart pull
decisions.
The git-receive-pack command is changed to invoke it at the end,
so just after a push to a public repository finishes via "git
push", the server info is automatically updated.
In addition, building of the rev-cache file can be done by a
standalone git-build-rev-cache command separately.
