14 93069372 2023-06-25 stsp Comparison to other version control systems
17 93069372 2023-06-25 stsp The user interface of the Got <a href="got.1.html">client</a> is heavily influenced
18 93069372 2023-06-25 stsp by Git, CVS, and SVN. Some inspiration was taken from Fossil and Mercurial.
20 93069372 2023-06-25 stsp <p>CVS and SVN users will find a familiar user interface which offers additional
21 93069372 2023-06-25 stsp commands for transferring changes between repositories across the network.
23 93069372 2023-06-25 stsp <p>Git users should be aware that Got treats every
24 93069372 2023-06-25 stsp <a href="git-repository.5.html">Git repository</a> as if it was <i>bare</i>.
25 93069372 2023-06-25 stsp This means Got completely ignores the Git work tree and the Git index.
26 93069372 2023-06-25 stsp A separate <a href="got-worktree.5.html">work tree</a> must be checked out from
27 93069372 2023-06-25 stsp a Git repository while working with Got.
29 93069372 2023-06-25 stsp <p>A unique feature of Got is its multi-process model working behind the scenes,
30 93069372 2023-06-25 stsp tailored to interfaces provided by the OpenBSD kernel.
31 93069372 2023-06-25 stsp Processes with an inherent attack surface, such as those talking to the network or
32 93069372 2023-06-25 stsp parsing the data in repositories, run in a separate address space and with
33 93069372 2023-06-25 stsp as little capabilities as possible.
34 93069372 2023-06-25 stsp The OpenBSD version of Got provides the strongest protections by using
35 93069372 2023-06-25 stsp <a href="https://man.openbsd.org/pledge">pledge</a> and
36 93069372 2023-06-25 stsp <a href="https://man.openbsd.org/unveil">unveil</a>
37 93069372 2023-06-25 stsp in combination.
38 93069372 2023-06-25 stsp For example, unveil enforces read-only access to repositories while the
39 93069372 2023-06-25 stsp Got <a href="gotd.8.html">server</a> is serving fetches.
40 93069372 2023-06-25 stsp The Got client main process restricts itself to the repository directory (read-only
41 3dd5e265 2023-06-28 bentley or read-write as appropriate), the <code>/tmp</code> directory, and the work tree.
42 93069372 2023-06-25 stsp Processes speaking the network protocol have no direct filesystem access at all.
43 93069372 2023-06-25 stsp All processes are pledged as tightly as possible to restrict the available system
44 93069372 2023-06-25 stsp calls to those required for regular operation.
45 93069372 2023-06-25 stsp The -portable version of Got uses Capsicum on FreeBSD and Landlock on Linux to restrict
46 93069372 2023-06-25 stsp filesystem access during network access and parsing of repository data, but does not
47 93069372 2023-06-25 stsp restrict the main process (yet?).
50 93069372 2023-06-25 stsp The table below lists network protocols supported by Got and some other systems.
51 93069372 2023-06-25 stsp For now, Got lacks support for Git's HTTP protocols, relying exclusively on
52 93069372 2023-06-25 stsp <a href="https://openssh.com">OpenSSH</a>.
53 93069372 2023-06-25 stsp Got clients interoperate well with popular Git hosting sites over SSH,
54 93069372 2023-06-25 stsp and Got servers can safely offer anonymous SSH access for public distribution.
