- Date:
add an initial implementation of gotadmin load
it is intended to be the counterpart of `gotadmin dump' and, just
like it, there's planned support for handling fast-import stream.
At the moment it only deals with git bundles.

- Date:
add an initial implementation of gotadmin dump
gotadmin dump is used to export (part of) the history of the
repository; at the moment it only generates git bundles (which are
pack files with a header) but support to generate a fast-import
stream is planned.

remove dependency of gitwrapper, gotctl, and gotsh on object_parse.c
Move some functions from object_parse.c into hash.c. These functions either
require hash.c code anyway or contain object ID implementation internals.
Add a new file object_qid.c, for got_object_id_queue and got_object_qid.
This new file must be linked to virtually every program.

rename lib/sha1.c to lib/hash.c
It will soon grow functions to deal with sha256 too. stsp@ agrees.

introduce gotd(8), a Git repository server reachable via ssh(1)
This is an initial barebones implementation which provides the absolute
minimum of functionality required to serve got(1) and git(1) clients.
Basic fetch/send functionality has been tested and seems to work here,
but this server is not yet expected to be stable.
More testing is welcome. See the man pages for setup instructions.
The current design uses one reader and one writer process per repository,
which will have to be extended to N readers and N writers in the future.
At startup, each process will chroot(2) into its assigned repository.
This works because gotd(8) can only be started as root, and will then
fork+exec, chroot, and privdrop.
At present the parent process runs with the following pledge(2) promises:
"stdio rpath wpath cpath proc getpw sendfd recvfd fattr flock unix unveil"
The parent is the only process able to modify the repository in a way
that becomes visible to Git clients. The parent uses unveil(2) to
restrict its view of the filesystem to /tmp and the repositories
listed in the configuration file gotd.conf(5).
Per-repository chroot(2) processes use "stdio rpath sendfd recvfd".
The writer defers to the parent for modifying references in the
repository to point at newly uploaded commits. The reader is fine
without such help, because Git repositories can be read without
having to create any lock-files.
gotd(8) requires a dedicated user ID, which should own repositories
on the filesystem, and a separate secondary group, which should not
have filesystem-level repository access, and must be allowed access
to the gotd(8) socket.
To obtain Git repository access, users must be members of this
secondary group, and must have their login shell set to gotsh(1).
gotsh(1) connects to the gotd(8) socket and speaks Git-protocol
towards the client on the other end of the SSH connection.
gotsh(1) is not an interactive command shell.
At present, authenticated clients are granted read/write access to
all repositories and all references (except for the "refs/got/" and
the "refs/remotes/" namespaces, which are already being protected
from modification).
While complicated access control mechanism are not a design goal,
making it possible to safely offer anonymous Git repository access
over ssh(1) is on the road map.

move code for reading Git's config file into new file read_gitconfig_privsep.c
The end goal here is to remove the dependency of repository.c on privsep.c
during compilation.

- Date:
move functions which open objects into new file object_open_privsep.c
For the future, this will make it possible to provide alternative
implementations of functions now stored in object_open_privsep.c.
This will probably be needed by future gotd(8) which runs inside
a chroot(2) environment and without the "exec" pledge(2) promise,
making it impossible to run libexec helpers on the fly.
Details of this design are not yet settled, but moving functions
into a separate compilation unit won't hurt in any case.

create and verify tags signed by SSH keys
This adds a new -s flag to 'got tag' that specifies the signer
identity (for example, a key file) of the tagger. The tag object will
include a signature that validates each of the tag object headers and
the tag message.
Verifying these signed tags requires maintaining an allowed signers
file which maps signer identities (i.e. the email address of the
tagger) to SSH public keys. See ssh-keygen(1) for more details of the
allowed signers file. After creating this file and providing the path
to it in got.conf(5) using the allowed_signers option, tags may be
verified using with 'got tag -V tag_name'. The return code will be
non-zero if a signature fails to verify.

let gotadmin find the repository automatically if invoked in a work tree
Move a small amount of code from worktree.c to a new file worktree_open.c,
which contains everything required to open and close a work tree and inspect
some of its basic parameters. This can be used by gotadmin.
