We recommend that gotsh users should not have direct filesystem access to repositories served by gotd. Which means admins will be setting things up as follows if public read-access should be denied: chown _gotd /git chmod 700 /git su -m _gotd -c 'gotadmin init /git/repo.git" However, gitwrapper would error out when repositories listed in gotd.conf were inaccessible to the user invoking gitwrapper: git-upload-pack: /etc/gotd.conf:2: realpath /git/repo.git: Permission denied Make gitwrapper ignore such errors as they are expected in this situation. While here, add a PROC_GITWRAPPER process ID for use as a global variable parse.y can check while special-casing any specific behaviour required by gitwrapper. (The worse alternative would have been adding a new global variable to parse.y just to control the behaviour on realpath errors.) ok op@
gotadmin dump is used to export (part of) the history of the repository; at the moment it only generates git bundles (which are pack files with a header) but support to generate a fast-import stream is planned. ok/tweaks stsp and jamsek
Reorganize the reference validation and pathlist generation by removing the reflist and building a pathlist directly. The pathlist entries record the object id in their extra data pointer, which also allows several redundant reference lookups to be skipped. This will eventually simplify sending target reference names that do not match the local repo by adding another parameter to insert_sendable_ref for a remote reference. This remote name will be added to the pathlist, but validation and object id lookups will continue to be performed with the local reference. ok jamsek
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. 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. A Got release tarball will install files under /usr/local by default. This default can be changed by passing PREFIX=/some/path to make. A build started in Got's Git repository will install files under ~/bin, which may have to be added to $PATH and be created first: $ mkdir ~/bin To compile the Got client 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) Tests will pass only after 'make install' because they rely on installed binaries in $PATH. Any tests written as shell scripts also 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 To test with packed repositories using the ref-delta representation for deltified objects, run: $ make regress GOT_TEST_PACK=ref-delta 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 The tog automated test suite is also run with 'make regress'. Like Got, however, individual tests or the entire suite can be run: $ cd regress/tog $ make # run all tests $ ./log.sh # run log view tests 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. To compile the Got server tool suite on OpenBSD, run: $ make obj $ make server $ make server-install This will install the following commands: gotd, the repository server program gotctl, the server control utility gotsh, the login shell for users accessing the server via the network gitwrapper, like mailwrapper(8) but for git-upload-pack and git-receive-pack See the following manual page files for information about server setup: $ man -l gotd/gotd.8 $ man -l gotd/gotd.conf.5 $ man -l gotctl/gotctl.8 $ man -l gotsh/gotsh.1 $ man -l gitwrapper/gitwrapper.1 See regress/gotd/README for information about running the server test suite. Game of Trees Web Daemon (gotwebd) is a FastCGI program which displays repository data and is designed to work with httpd(8). To compile gotwebd on OpenBSD, run: $ make webd # make webd-install This will create the following files: the daemon program /usr/local/sbin/gotwebd css and image files in /var/www/htdocs/gotwebd the gotwebd init script in /etc/rc.d man pages (only installed if building sources from a Got release tarball) Documentation is available in manual pages: $ man -l gotwebd/gotwebd.8 $ man -l gotwebd/gotwebd.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 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. 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.
