When set to "warn" or "error", `rebase.missingCommitsCheck' would make `rebase -i' warn if the user removed commits from the todo list to prevent mistakes. Unfortunately, `rebase --edit-todo' and `rebase --continue' don't take it into account. This adds the ability for `rebase --edit-todo' and `rebase --continue' to check if commits were dropped by the user. As both edit_todo_list() and complete_action() parse the todo list and check for dropped commits, the code doing so in the latter is removed to reduce duplication. `edit_todo_list_advice' is removed from sequencer.c as it is no longer used there. This changes when a backup of the todo list is made. Until now, it was saved only once, before the initial edit. Now, it is also made if the original todo list has no errors or no dropped commits. Thus, the backup should be error-free. Without this, sequencer_continue() (`rebase --continue') could only compare the current todo list against the original, unedited list. Before this change, this file was only used by edit_todo_list() and `rebase -p' to create the backup before the initial edit, and check_todo_list_from_file(), only used by `rebase -p' to check for dropped commits after its own initial edit. If the edited list has an error, a file, `dropped', is created to report the issue. Otherwise, it is deleted. Usually, the edited list is compared against the list before editing, but if this file exists, it will be compared to the backup. Also, if the file exists, sequencer_continue() checks the list for dropped commits. If the check was performed every time, it would fail when resuming a rebase after resolving a conflict, as the backup will contain commits that were picked, but they will not be in the new list. It's safe to ignore this check if `dropped' does not exist, because that means that no errors were found at the last edition, so any missing commits here have already been picked. Five tests are added to t3404. The tests for `rebase.missingCommitsCheck = warn' and `rebase.missingCommitsCheck = error' have a similar structure. First, we start a rebase with an incorrect command on the first line. Then, we edit the todo list, removing the first and the last lines. This demonstrates that `--edit-todo' notices dropped commits, but not when the command is incorrect. Then, we restore the original todo list, and edit it to remove the last line. This demonstrates that if we add a commit after the initial edit, then remove it, `--edit-todo' will notice that it has been dropped. Then, the actual rebase takes place. In the third test, it is also checked that `--continue' will refuse to resume the rebase if commits were dropped. The fourth test checks that no errors are raised when resuming a rebase after resolving a conflict, the fifth checks that no errors are raised when editing the todo list after pausing the rebase.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
