626 Rebase commits on the specified
628 onto the tip of the current branch of the work tree.
631 must share common ancestry with the work tree's current branch.
632 Rebasing begins with the first descendent commit of the youngest
633 common ancestor commit shared by the specified
635 and the work tree's current branch, and stops once the tip commit
640 Rebased commits are accumulated on a temporary branch which the work tree
641 will remain switched to throughout the entire rebase operation.
642 Commits on this branch represent the same changes with the same log
643 messages as their counterparts on the original
645 but with different commit IDs.
646 Once rebasing has completed successfully, the temporary branch becomes
647 the new version of the specified
649 and the work tree is automatically switched to it.
651 While rebasing commits, show the status of each affected file,

663 If merge conflicts occur the rebase operation is interrupted and may
664 be continued once conflicts have been resolved.
665 Alternatively, the rebase operation may be aborted which will leave
667 unmodified and the work tree switched back to its original branch.
669 If a merge conflict is resolved in a way which renders the merged
670 change into a no-op change, the corresponding commit will be elided
671 when the rebase operation continues.

694 conflict resolution purposes.

711 Edit commit history between the work tree's current base commit and
712 the tip commit of the work tree's current branch.
714 Editing of commit history is controlled via a
716 which can be edited interactively or passed on the command line.
717 The format of the histedit script is line-based.
718 Each line in the script begins with a command name, followed by
719 whitespace and an argument.
720 For most commands, the expected argument is a commit ID SHA1 hash.
721 Any remaining text on the line is ignored.
722 Lines which begin with the
724 character are ignored entirely.
726 The available commands are as follows:
727 .Bl -column YXZ pick-commit
728 .It pick Ar commit Ta Use the specified commit as it is.
729 .It edit Ar commit Ta Use the specified commit but once changes have been
730 merged into the work tree interrupt the histedit operation for amending.
731 .It fold Ar commit Ta Combine the specified commit with the next commit
732 listed further below that will be used.
733 .It drop Ar commit Ta Remove this commit from the edited history.
734 .It mesg Ar log-message Ta Use the specified single-line log message for
735 the commit on the previous line.
736 If the log message argument is left empty, open an editor where a new
737 log message can be written.
740 Every commit in the history being edited must be mentioned in the script.
741 Lines may be re-ordered to change the order of commits in the edited history.
743 Edited commits are accumulated on a temporary branch which the work tree
744 will remain switched to throughout the entire histedit operation.
745 Once history editing has completed successfully, the temporary branch becomes
746 the new version of the work tree's branch and the work tree is automatically

761 If merge conflicts occur the histedit operation is interrupted and may
762 be continued once conflicts have been resolved.
763 Alternatively, the histedit operation may be aborted which will leave
764 the work tree switched back to its original branch.
766 If a merge conflict is resolved in a way which renders the merged
767 change into a no-op change, the corresponding commit will be elided
768 when the histedit operation continues.

772 If the work tree's current branch is not in the
774 reference namespace, the history of the branch may not be edited.

842 Check out a work tree from the Git repository to /usr/src:

863 Switch an existing work tree to the branch
864 .Dq unified-buffer-cache .
865 Local changes in the work tree will be preserved and merged if necessary:
867 .Dl $ got update -b unified-buffer-cache
869 Create a new commit from local changes in a work tree directory.
870 This new commit will become the head commit of the work tree's current branch:
874 In a work tree or a git repository directory, view changes committed in
875 the 3 most recent commits to the work tree's branch, or the branch resolved
876 via the repository's HEAD reference, respectively:

880 Add new files and remove obsolete files in a work tree directory:
882 .Dl $ got add sys/uvm/uvm_ubc.c
883 .Dl $ got remove sys/uvm/uvm_vnode.c
885 Create a new commit from local changes in a work tree directory
886 with a pre-defined log message.
888 .Dl $ got commit -m 'unify the buffer cache'
890 Update any work tree checked out from the

896 Roll file content on the unified-buffer-cache branch back by one commit,

901 .Dl $ got commit -m 'roll back previous'
902 .Dl $ # now back out the previous backout :-)
903 .Dl $ got backout unified-buffer-cache

934 Additional steps are necessary if local changes need to be pushed back
935 to the remote repository, which currently requires
939 Before working against existing branches in a repository cloned with
940 .Dq git clone --bare ,
943 must be configured to map all references in the remote repository
946 namespace of the local repository.
947 This can achieved by setting Git's
948 .Pa remote.origin.fetch
949 configuration variable to the value
950 .Dq +refs/heads/*:refs/remotes/origin/*
955 .Dl $ cd /var/git/repo
956 .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*'
958 Alternatively, the following
960 configuration item can be added manually to the Git repository's
964 .Dl [remote "origin"]
966 .Dl fetch = +refs/heads/*:refs/remotes/origin/*
968 This configuration leaves the local repository's
970 namespace free for use by local branches checked out with
972 and, if needed, created with
977 namespace can be updated with incoming changes from the remote
981 .Dl $ cd /var/git/repo
984 Before outgoing changes on the local
986 branch can be pushed to the remote repository, the local
988 branch must be rebased onto the
992 .Dl $ got update -b origin/master
993 .Dl $ got rebase master
997 branch can then be pushed to the remote
1001 .Dl $ cd /var/git/repo
1002 .Dl $ git push origin master

1014 is a work-in-progress and many commands remain to be implemented.
1015 At present, the user has to fall back on
1017 to perform many tasks, in particular tasks related to repository
1018 administration and tasks which require a network connection.
