rebase -i: remove git-rebase--interactive.sh

2018-10-09T01:44:10Z

This removes git-rebase--interactive.sh, as its functionnality has been replaced by git-rebase--interactive2. git-rebase--interactive2.c is then renamed to git-rebase--interactive.c. Signed-off-by: Alban Gruin Signed-off-by: Junio C Hamano

rebase -i: implement the main part of interactive rebase as a builtin

2018-10-09T01:44:10Z

This rewrites the part of interactive rebase which initializes the basic state, make the script and complete the action, as a buitin, named git-rebase--interactive2 for now. Others modes (`--continue`, `--edit-todo`, etc.) will be rewritten in the next commit. git-rebase--interactive.sh is modified to call git-rebase--interactive2 instead of git-rebase--helper.

rebase -i: rewrite init_basic_state() in C

2018-08-29T20:38:18Z

This rewrites init_basic_state() from shell to C. The call to write_basic_state() in cmd_rebase__helper() is replaced by a call to the new function. The shell version is then stripped from git-rebase--interactive.sh. Signed-off-by: Alban Gruin Signed-off-by: Junio C Hamano

rebase -i: rewrite write_basic_state() in C

2018-08-29T20:38:18Z

This rewrites write_basic_state() from git-rebase.sh in C. This is the first step in the conversion of init_basic_state(), hence the mode in rebase--helper.c is called INIT_BASIC_STATE. init_basic_state() will be converted in the next commit. The part of read_strategy_opts() that parses the stategy options is moved to a new function to allow its use in rebase--helper.c. Finally, the call to write_basic_state() is removed from git-rebase--interactive.sh, replaced by a call to `--init-basic-state`. Signed-off-by: Alban Gruin Signed-off-by: Junio C Hamano

rebase -i: rewrite the rest of init_revisions_and_shortrevisions() in C

2018-08-29T20:38:18Z

This rewrites the part of init_revisions_and_shortrevisions() needed by `--complete-action` (which initialize $shortrevisions) from shell to C. When `upstream` is empty, it means that the user launched a `rebase --root`, and `onto` contains the ID of an empty commit. As a range between an empty commit and `head` is not really meaningful, `onto` is not used to initialize `shortrevisions` in this case. The corresponding arguments passed to `--complete-action` are then dropped, and init_revisions_and_shortrevisions() is stripped from git-rebase--interactive.sh Signed-off-by: Alban Gruin Signed-off-by: Junio C Hamano

rebase -i: implement the logic to initialize $revisions in C

2018-08-29T20:38:18Z

This rewrites the part of init_revisions_and_shortrevisions() needed by `--make-script` from shell to C. The new version is called get_revision_ranges(), and is a static function inside of rebase--helper.c. As this does not initialize $shortrevision, the original shell version is not yet stripped. Unlike init_revisions_and_shortrevisions(), get_revision_ranges() doesn’t write $squash_onto to the state directory, it’s done by the handler of `--make-script` instead. Finally, this drops the $revision argument passed to `--make-script` in git-rebase--interactive.sh, and rebase--helper is changed accordingly.

rebase -i: remove unused modes and functions

2018-08-29T20:38:18Z

This removes the modes `--skip-unnecessary-picks`, `--append-todo-help`, and `--checkout-onto` from rebase--helper.c, the functions of git-rebase--interactive.sh that were rendered useless by the rewrite of complete_action(), and append_todo_help_to_file() from rebase-interactive.c. skip_unnecessary_picks() and checkout_onto() becomes static, as they are only used inside of the sequencer.

rebase -i: rewrite complete_action() in C

2018-08-29T20:38:18Z

This rewrites complete_action() from shell to C. A new mode is added to rebase--helper (`--complete-action`), as well as a new flag (`--autosquash`). Finally, complete_action() is stripped from git-rebase--interactive.sh. The original complete_action() would return the code 2 when the todo list contained no actions. This was a special case for rebase -i and -p; git-rebase.sh would then apply the autostash, delete the state directory, and die with the message "Nothing to do". This cleanup is rewritten in C instead of returning 2. As rebase -i no longer returns 2, the comment describing this behaviour in git-rebase.sh is updated to reflect this change. The message "Nothing to do" is now printed with error(), and so becomes "error: nothing to do". Some tests in t3404 check this value, so they are updated to fit this change. The first check might seem useless as we write "noop" to the todo list if it is empty. Actually, the todo list might contain commented commands (ie. empty commits). In this case, complete_action() won’t write "noop", and will abort without starting the editor. Signed-off-by: Alban Gruin Signed-off-by: Junio C Hamano

rebase -i: rewrite checkout_onto() in C

2018-08-10T18:56:22Z

This rewrites checkout_onto() from shell to C. A new command (“checkout-onto”) is added to rebase--helper.c. The shell version is then stripped. Signed-off-by: Alban Gruin Signed-off-by: Junio C Hamano

rebase -i: rewrite setup_reflog_action() in C

2018-08-10T18:56:22Z

This rewrites (the misnamed) setup_reflog_action() from shell to C. The new version is called prepare_branch_to_be_rebased(). A new command is added to rebase--helper.c, “checkout-base”, as well as a new flag, “verbose”, to avoid silencing the output of the checkout operation called by checkout_base_commit(). The function `run_git_checkout()` will also be used in the next commit, therefore its code is not part of `checkout_base_commit()`. The shell version is then stripped in favour of a call to the helper. As $GIT_REFLOG_ACTION is no longer set at the first call of checkout_onto(), a call to comment_for_reflog() is added at the beginning of this function.
