Game of Trees (Got) is a version control system which prioritizes ease of use and simplicity over flexibility (https://gameoftrees.org) Got is still under development; it is being developed exclusively on OpenBSD and its target audience are OpenBSD developers. Got is ISC-licensed and was designed with pledge(2) and unveil(2) in mind. Got uses Git repositories to store versioned data. At present, Got supports local version control operations only. Git can be used for any functionality which has not yet been implemented in Got. It will always remain possible to work with both Got and Git on the same repository. To compile the Got tool suite on OpenBSD, run: $ make obj $ make $ make install This will install the following commands: got, the command line interface tog, an ncurses-based interactive Git repository browser several helper programs from the libexec directory man pages (only installed if building sources from a Got release tarball) A Got release tarball will install files under /usr/local by default. A build started in Got's Git repository will install files under ~/bin. Tests will pass only after 'make install' because they rely on installed binaries in $PATH. Tests in the cmdline directory currently depend on git(1). Tests which use the got clone, fetch, and send commands will fail if 'ssh 127.0.0.1' does not succeed non-interactively. $ doas pkg_add git $ make regress To test with packed repositories, run: $ make regress GOT_TEST_PACK=1 Because got unveils the /tmp directory by default using the /tmp directory for test data can hide bugs. However, /tmp remains the default because there is no better alternative that works out of the box. In order to store test data in a directory other than /tmp, such as ~/got-test, run: $ mkdir ~/got-test $ make regress GOT_TEST_ROOT=~/got-test Man page files in the Got source tree can be viewed with 'man -l': $ man -l got/got.1 $ man -l got/git-repository.5 $ man -l got/got-worktree.5 $ man -l tog/tog.1 EXAMPLES in got.1 contains a quick-start guide for OpenBSD developers. Game of Trees Web (Gotweb) is a CGI program which displays repository data and is designed to work with httpd(8) and slowcgi(8). It requires the Kristaps Dzonsons kcgi library, version 0.12.0 or greater. To compile gotweb on OpenBSD, run: # pkg_add kcgi $ make web # make web-install This will create the following files: the CGI program /var/www/cgi-bin/gotweb/gotweb helper programs from the libexec directory in /var/www/cgi-bin/gotweb/libexec several template files in /var/www/cgi-bin/gw_tmpl/ html, css, and image files in /var/www/htdocs/gotweb/ the directory /var/www/got/tmp/ man pages (only installed if building sources from a Got release tarball) Documentation is available in manual pages: $ man -l gotweb/gotweb.8 $ man -l gotweb/gotweb.conf.5 Got can be built with profiling enabled to debug performance issues. Note that profiled builds cannot make use of pledge(2). Profiling should only be enabled for one program at a time. Otherwise, multiple programs will attempt to write to the 'gmon.out' file in the current working directory. For example, to compile got-read-pack with profiling enabled: $ cd libexec/got-read-pack $ make clean $ make PROFILE=1 $ make install Running any Got command which ends up using got-read-pack should now produce the file 'gmon.out' in the current working directory. The gprof2dot program can be used to generate a profile graph: $ doas pkg_add gprof2dot graphviz $ gprof ~/bin/got-read-pack gmon.out | gprof2dot | dot -T png > profile.png As another example, to compile gotweb with profiling enabled: $ cd gotweb $ make clean $ make PROFILE=1 gotweb $ make # compile remaining gotweb binaries as usual $ doas make install $ doas chown www /var/www/cgi-bin/gotweb/ After loading a gotweb page in the browser, there should now be a gmon.out file next to the gotweb binary: $ ls -l /var/www/cgi-bin/gotweb/ total 6088 -rw-r--r-- 1 www daemon 427642 Jun 17 22:04 gmon.out -rwxr-xr-x 1 www www 2630488 Jun 17 22:03 gotweb drwxr-xr-x 2 root daemon 512 Jun 17 22:03 gw_tmpl drwxr-xr-x 2 root daemon 512 Jun 17 22:03 libexec Guidelines for reporting problems: All problem/bug reports should include a reproduction recipe in form of a shell script which starts out with an empty repository and runs a series of Got and/or Git commands to trigger the problem, be it a crash or some other undesirable behaviour. The regress/cmdline directory contains plenty of example scripts. An ideal reproduction recipe is written as an xfail ("expected failure") regression test. For a real-world example of an xfail test, see commits 4866d0842a2b34812818685aaa31d3e0a966412d and 2b496619daecc1f25b1bc0c53e01685030dc2c74 in Got's history. Please take this request very seriously; Ask for help with writing your regression test before asking for your problem to be fixed. Time invested in writing a regression test saves time wasted on back-and-forth discussion about how the problem can be reproduced. A regression test will need to be written in any case to verify a fix and prevent the problem from resurfacing. It is also possible to write test cases in C. Various examples of this exist in the regress/ directory. Most such tests are unit tests; it is unlikely that a problem found during regular usage will require a test to be written in C. Some areas of code, such as the tog UI, are not covered by automated tests. Please always try to find a way to trigger your problem via the command line interface before reporting a problem without a written test case included. If writing an automated test really turns out to be impossible, please explain in very clear terms how the problem can be reproduced.
