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. Git can be used
9 for any functionality which has not yet been implemented in Got.
10 It will always remain possible to work with both Got and Git on
13 A Got release tarball will install files under /usr/local by default.
14 This default can be changed by passing PREFIX=/some/path to make.
16 A build started in Got's Git repository will install files under ~/bin,
17 which may have to be added to $PATH and be created first:
21 To compile the Got client tool suite on OpenBSD, run:
27 This will install the following commands:
29 got, the command line interface
30 tog, an ncurses-based interactive Git repository browser
31 several helper programs from the libexec directory
32 man pages (only installed if building sources from a Got release tarball)
34 Tests will pass only after 'make install' because they rely on installed
35 binaries in $PATH. Any tests written as shell scripts also depend on git(1).
36 Tests which use the got clone, fetch, and send commands will fail if
37 'ssh 127.0.0.1' does not succeed non-interactively.
39 Tests for HTTP protocol support rely on the HTTP::Daemon Perl module.
41 $ doas pkg_add git p5-http-daemon
44 To test with packed repositories, run:
46 $ make regress GOT_TEST_PACK=1
48 To test with packed repositories using the ref-delta representation for
49 deltified objects, run:
51 $ make regress GOT_TEST_PACK=ref-delta
53 Because got unveils the /tmp directory by default using the /tmp directory
54 for test data can hide bugs. However, /tmp remains the default because
55 there is no better alternative that works out of the box. In order to
56 store test data in a directory other than /tmp, such as ~/got-test, run:
59 $ make regress GOT_TEST_ROOT=~/got-test
61 The tog automated test suite is also run with 'make regress'.
62 Like Got, however, individual tests or the entire suite can be run:
65 $ make # run all tests
66 $ ./log.sh # run log view tests
68 Man page files in the Got source tree can be viewed with 'man -l':
71 $ man -l got/git-repository.5
72 $ man -l got/got-worktree.5
75 EXAMPLES in got.1 contains a quick-start guide for OpenBSD developers.
78 To compile the Got server tool suite on OpenBSD, run:
84 This will install the following commands:
86 gotd, the repository server program
87 gotctl, the server control utility
88 gotsh, the login shell for users accessing the server via the network
89 gitwrapper, like mailwrapper(8) but for git-upload-pack and git-receive-pack
91 See the following manual page files for information about server setup:
94 $ man -l gotd/gotd.conf.5
95 $ man -l gotctl/gotctl.8
96 $ man -l gotsh/gotsh.1
97 $ man -l gitwrapper/gitwrapper.1
99 See regress/gotd/README for information about running the server test suite.
102 Game of Trees Web Daemon (gotwebd) is a FastCGI program which displays
103 repository data and is designed to work with httpd(8).
105 To compile gotwebd on OpenBSD, run:
110 This will create the following files:
111 the daemon program /usr/local/sbin/gotwebd
112 css and image files in /var/www/htdocs/gotwebd
113 the gotwebd init script in /etc/rc.d
114 man pages (only installed if building sources from a Got release tarball)
116 Documentation is available in manual pages:
118 $ man -l gotwebd/gotwebd.8
119 $ man -l gotwebd/gotwebd.conf.5
122 Got can be built with profiling enabled to debug performance issues.
123 Note that profiled builds cannot make use of pledge(2).
124 Profiling should only be enabled for one program at a time. Otherwise,
125 multiple programs will attempt to write to the 'gmon.out' file in the
126 current working directory.
128 For example, to compile got-read-pack with profiling enabled:
130 $ cd libexec/got-read-pack
135 Running any Got command which ends up using got-read-pack should now
136 produce the file 'gmon.out' in the current working directory.
137 The gprof2dot program can be used to generate a profile graph:
139 $ doas pkg_add gprof2dot graphviz
140 $ gprof ~/bin/got-read-pack gmon.out | gprof2dot | dot -T png > profile.png
143 Guidelines for reporting problems:
145 All problem/bug reports should include a reproduction recipe in form of a
146 shell script which starts out with an empty repository and runs a series of
147 Got and/or Git commands to trigger the problem, be it a crash or some other
148 undesirable behaviour.
150 The regress/cmdline directory contains plenty of example scripts.
151 An ideal reproduction recipe is written as an xfail ("expected failure")
152 regression test. For a real-world example of an xfail test, see commits
153 4866d0842a2b34812818685aaa31d3e0a966412d and
154 2b496619daecc1f25b1bc0c53e01685030dc2c74 in Got's history.
156 Please take this request very seriously; Ask for help with writing your
157 regression test before asking for your problem to be fixed. Time invested
158 in writing a regression test saves time wasted on back-and-forth discussion
159 about how the problem can be reproduced. A regression test will need to be
160 written in any case to verify a fix and prevent the problem from resurfacing.
162 It is also possible to write test cases in C. Various examples of this
163 exist in the regress/ directory. Most such tests are unit tests; it is
164 unlikely that a problem found during regular usage will require a test
167 Please always try to find a way to trigger your problem via the command line
168 interface before reporting a problem without a written test case included.
169 If writing an automated test really turns out to be impossible, please
170 explain in very clear terms how the problem can be reproduced.
