1 Game of Trees (Got) is a version control system which prioritizes ease
2 of use and simplicity over flexibility (https://gameoftrees.org)
4 Got is still under development; it is being developed exclusively
5 on OpenBSD and its target audience are OpenBSD developers. Got is
6 ISC-licensed and was designed with pledge(2) and unveil(2) in mind.
8 Got uses Git repositories to store versioned data. At present, Got
9 supports local version control operations only. Git can be used
10 for any functionality which has not yet been implemented in Got.
11 It will always remain possible to work with both Got and Git on
14 To compile the Got client tool suite on OpenBSD, run:
20 This will install the following commands:
22 got, the command line interface
23 tog, an ncurses-based interactive Git repository browser
24 several helper programs from the libexec directory
25 man pages (only installed if building sources from a Got release tarball)
27 A Got release tarball will install files under /usr/local by default.
28 A build started in Got's Git repository will install files under ~/bin.
30 Tests will pass only after 'make install' because they rely on installed
31 binaries in $PATH. Tests in the cmdline directory currently depend on git(1).
32 Tests which use the got clone, fetch, and send commands will fail if
33 'ssh 127.0.0.1' does not succeed non-interactively.
38 To test with packed repositories, run:
40 $ make regress GOT_TEST_PACK=1
42 To test with packed repositories using the ref-delta representation for
43 deltified objects, run:
45 $ make regress GOT_TEST_PACK=ref-delta
47 Because got unveils the /tmp directory by default using the /tmp directory
48 for test data can hide bugs. However, /tmp remains the default because
49 there is no better alternative that works out of the box. In order to
50 store test data in a directory other than /tmp, such as ~/got-test, run:
53 $ make regress GOT_TEST_ROOT=~/got-test
55 Man page files in the Got source tree can be viewed with 'man -l':
58 $ man -l got/git-repository.5
59 $ man -l got/got-worktree.5
62 EXAMPLES in got.1 contains a quick-start guide for OpenBSD developers.
65 To compile the Got server tool suite on OpenBSD, run:
71 This will install the following commands:
73 gotd, the repository server program
74 gotctl, the server control utility
75 gotsh, the login shell for users accessing the server via the network
77 See the following manual page files for information about server setup:
80 $ man -l gotd/gotd.conf.5
81 $ man -l gotctl/gotctl.8
82 $ man -l gotsh/gotsh.1
84 See regress/gotd/README for information about running the server test suite.
87 Game of Trees Web Daemon (gotwebd) is a FastCGI program which displays
88 repository data and is designed to work with httpd(8).
90 To compile gotwebd on OpenBSD, run:
95 This will create the following files:
96 the daemon program /usr/local/sbin/gotwebd
97 css and image files in /var/www/htdocs/gotwebd
98 the gotwebd init script in /etc/rc.d
99 man pages (only installed if building sources from a Got release tarball)
101 Documentation is available in manual pages:
103 $ man -l gotwebd/gotwebd.8
104 $ man -l gotwebd/gotwebd.conf.5
107 Got can be built with profiling enabled to debug performance issues.
108 Note that profiled builds cannot make use of pledge(2).
109 Profiling should only be enabled for one program at a time. Otherwise,
110 multiple programs will attempt to write to the 'gmon.out' file in the
111 current working directory.
113 For example, to compile got-read-pack with profiling enabled:
115 $ cd libexec/got-read-pack
120 Running any Got command which ends up using got-read-pack should now
121 produce the file 'gmon.out' in the current working directory.
122 The gprof2dot program can be used to generate a profile graph:
124 $ doas pkg_add gprof2dot graphviz
125 $ gprof ~/bin/got-read-pack gmon.out | gprof2dot | dot -T png > profile.png
128 Guidelines for reporting problems:
130 All problem/bug reports should include a reproduction recipe in form of a
131 shell script which starts out with an empty repository and runs a series of
132 Got and/or Git commands to trigger the problem, be it a crash or some other
133 undesirable behaviour.
135 The regress/cmdline directory contains plenty of example scripts.
136 An ideal reproduction recipe is written as an xfail ("expected failure")
137 regression test. For a real-world example of an xfail test, see commits
138 4866d0842a2b34812818685aaa31d3e0a966412d and
139 2b496619daecc1f25b1bc0c53e01685030dc2c74 in Got's history.
141 Please take this request very seriously; Ask for help with writing your
142 regression test before asking for your problem to be fixed. Time invested
143 in writing a regression test saves time wasted on back-and-forth discussion
144 about how the problem can be reproduced. A regression test will need to be
145 written in any case to verify a fix and prevent the problem from resurfacing.
147 It is also possible to write test cases in C. Various examples of this
148 exist in the regress/ directory. Most such tests are unit tests; it is
149 unlikely that a problem found during regular usage will require a test
152 Some areas of code, such as the tog UI, are not covered by automated tests.
153 Please always try to find a way to trigger your problem via the command line
154 interface before reporting a problem without a written test case included.
155 If writing an automated test really turns out to be impossible, please
156 explain in very clear terms how the problem can be reproduced.
