document new regress dependency on p5-http-daemon

make installation prefix info more visible in README

run the tog tests as part of the default regress set ok and README update by jamsek

remove outdated information from README

update regress test info in README

tog: implement automated test harness Add framework for scripting tog tests by capturing screen dumps to compare with expected output. Includes some preliminary log view tests but lots more tests are needed to cover diff, blame, tree, ref, and help views. ok stsp@

add gitwrapper(1) ok op@, tracey@ earlier version

mention GOT_TEST_PACK=ref-delta in the README too

gotwebd is a Web daemon

farewell, gotweb. you served us well. rm gotweb, ok stsp@

add a test suite for gotd(8); check basic clone and send functionality

add gotctl(8); initially supported commands are 'info' and 'stop' This will be used by an upcoming regress test suite for gotd(8). ok tracey

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.
