+[[summary]]
+== Summary
+
+This is a tutorial demonstrating the end-to-end workflow of creating a change to
+the Git tree, sending it for review, and making changes based on comments.
+
+[[prerequisites]]
+=== Prerequisites
+
+This tutorial assumes you're already fairly familiar with using Git to manage
+source code. The Git workflow steps will largely remain unexplained.
+
+[[related-reading]]
+=== Related Reading
+
+This tutorial aims to summarize the following documents, but the reader may find
+useful additional context:
+
+- `Documentation/SubmittingPatches`
+- `Documentation/howto/new-command.txt`
+
+[[getting-started]]
+== Getting Started
+
+[[cloning]]
+=== Clone the Git Repository
+
+Git is mirrored in a number of locations. Clone the repository from one of them;
+https://git-scm.com/downloads suggests one of the best places to clone from is
+the mirror on GitHub.
+
+----
+$ git clone https://github.com/git/git git
+$ cd git
+----
+
+[[identify-problem]]
+=== Identify Problem to Solve
+
+////
+Use + to indicate fixed-width here; couldn't get ` to work nicely with the
+quotes around "Pony Saying 'Um, Hello'".
+////
+In this tutorial, we will add a new command, +git psuh+, short for ``Pony Saying
+`Um, Hello''' - a feature which has gone unimplemented despite a high frequency
+of invocation during users' typical daily workflow.
+
+(We've seen some other effort in this space with the implementation of popular
+commands such as `sl`.)
+
+[[setup-workspace]]
+=== Set Up Your Workspace
+
+Let's start by making a development branch to work on our changes. Per
+`Documentation/SubmittingPatches`, since a brand new command is a new feature,
+it's fine to base your work on `master`. However, in the future for bugfixes,
+etc., you should check that document and base it on the appropriate branch.
+
+For the purposes of this document, we will base all our work on the `master`
+branch of the upstream project. Create the `psuh` branch you will use for
+development like so:
+
+----
+$ git checkout -b psuh origin/master
+----
+
+We'll make a number of commits here in order to demonstrate how to send a topic
+with multiple patches up for review simultaneously.
+
+[[code-it-up]]
+== Code It Up!
+
+NOTE: A reference implementation can be found at
+https://github.com/nasamuffin/git/tree/psuh.
+
+[[add-new-command]]
+=== Adding a New Command
+
+Lots of the subcommands are written as builtins, which means they are
+implemented in C and compiled into the main `git` executable. Implementing the
+very simple `psuh` command as a built-in will demonstrate the structure of the
+codebase, the internal API, and the process of working together as a contributor
+with the reviewers and maintainer to integrate this change into the system.
+
+Built-in subcommands are typically implemented in a function named "cmd_"
+followed by the name of the subcommand, in a source file named after the
+subcommand and contained within `builtin/`. So it makes sense to implement your
+command in `builtin/psuh.c`. Create that file, and within it, write the entry
+point for your command in a function matching the style and signature:
+
+----
+int cmd_psuh(int argc, const char **argv, const char *prefix)
+----
+
+We'll also need to add the declaration of psuh; open up `builtin.h`, find the
+declaration for `cmd_push`, and add a new line for `psuh` immediately before it,
+in order to keep the declarations sorted:
+
+----
+int cmd_psuh(int argc, const char **argv, const char *prefix);
+----
+
+Be sure to `#include "builtin.h"` in your `psuh.c`.
+
+Go ahead and add some throwaway printf to that function. This is a decent
+starting point as we can now add build rules and register the command.
+
+NOTE: Your throwaway text, as well as much of the text you will be adding over
+the course of this tutorial, is user-facing. That means it needs to be
+localizable. Take a look at `po/README` under "Marking strings for translation".
+Throughout the tutorial, we will mark strings for translation as necessary; you
+should also do so when writing your user-facing commands in the future.
+
+----
+int cmd_psuh(int argc, const char **argv, const char *prefix)
+{
+ printf(_("Pony saying hello goes here.\n"));
+ return 0;
+}
+----
+
+Let's try to build it. Open `Makefile`, find where `builtin/push.o` is added
+to `BUILTIN_OBJS`, and add `builtin/psuh.o` in the same way next to it in
+alphabetical order. Once you've done so, move to the top-level directory and
+build simply with `make`. Also add the `DEVELOPER=1` variable to turn on
+some additional warnings:
+
+----
+$ echo DEVELOPER=1 >config.mak
+$ make
+----
+
+NOTE: When you are developing the Git project, it's preferred that you use the
+`DEVELOPER` flag; if there's some reason it doesn't work for you, you can turn
+it off, but it's a good idea to mention the problem to the mailing list.
+
+NOTE: The Git build is parallelizable. `-j#` is not included above but you can
+use it as you prefer, here and elsewhere.
+
+Great, now your new command builds happily on its own. But nobody invokes it.
+Let's change that.
+
+The list of commands lives in `git.c`. We can register a new command by adding
+a `cmd_struct` to the `commands[]` array. `struct cmd_struct` takes a string
+with the command name, a function pointer to the command implementation, and a
+setup option flag. For now, let's keep mimicking `push`. Find the line where
+`cmd_push` is registered, copy it, and modify it for `cmd_psuh`, placing the new
+line in alphabetical order.
+
+The options are documented in `builtin.h` under "Adding a new built-in." Since
+we hope to print some data about the user's current workspace context later,
+we need a Git directory, so choose `RUN_SETUP` as your only option.
+
+Go ahead and build again. You should see a clean build, so let's kick the tires
+and see if it works. There's a binary you can use to test with in the
+`bin-wrappers` directory.
+
+----
+$ ./bin-wrappers/git psuh
+----
+
+Check it out! You've got a command! Nice work! Let's commit this.
+
+`git status` reveals modified `Makefile`, `builtin.h`, and `git.c` as well as
+untracked `builtin/psuh.c` and `git-psuh`. First, let's take care of the binary,
+which should be ignored. Open `.gitignore` in your editor, find `/git-push`, and
+add an entry for your new command in alphabetical order:
+
+----
+...
+/git-prune-packed
+/git-psuh
+/git-pull
+/git-push
+/git-quiltimport
+/git-range-diff
+...
+----
+
+Checking `git status` again should show that `git-psuh` has been removed from
+the untracked list and `.gitignore` has been added to the modified list. Now we
+can stage and commit:
+
+----
+$ git add Makefile builtin.h builtin/psuh.c git.c .gitignore
+$ git commit -s
+----
+
+You will be presented with your editor in order to write a commit message. Start
+the commit with a 50-column or less subject line, including the name of the
+component you're working on, followed by a blank line (always required) and then
+the body of your commit message, which should provide the bulk of the context.
+Remember to be explicit and provide the "Why" of your change, especially if it
+couldn't easily be understood from your diff. When editing your commit message,
+don't remove the Signed-off-by line which was added by `-s` above.
+
+----
+psuh: add a built-in by popular demand
+
+Internal metrics indicate this is a command many users expect to be
+present. So here's an implementation to help drive customer
+satisfaction and engagement: a pony which doubtfully greets the user,
+or, a Pony Saying "Um, Hello" (PSUH).
+
+This commit message is intentionally formatted to 72 columns per line,
+starts with a single line as "commit message subject" that is written as
+if to command the codebase to do something (add this, teach a command
+that). The body of the message is designed to add information about the
+commit that is not readily deduced from reading the associated diff,
+such as answering the question "why?".
+
+Signed-off-by: A U Thor <author@example.com>
+----
+
+Go ahead and inspect your new commit with `git show`. "psuh:" indicates you
+have modified mainly the `psuh` command. The subject line gives readers an idea
+of what you've changed. The sign-off line (`-s`) indicates that you agree to
+the Developer's Certificate of Origin 1.1 (see the
+`Documentation/SubmittingPatches` +++[[dco]]+++ header).
+
+For the remainder of the tutorial, the subject line only will be listed for the
+sake of brevity. However, fully-fleshed example commit messages are available
+on the reference implementation linked at the top of this document.
+
+[[implementation]]
+=== Implementation
+
+It's probably useful to do at least something besides printing out a string.
+Let's start by having a look at everything we get.
+
+Modify your `cmd_psuh` implementation to dump the args you're passed, keeping
+existing `printf()` calls in place:
+
+----
+ int i;
+
+ ...
+
+ printf(Q_("Your args (there is %d):\n",
+ "Your args (there are %d):\n",
+ argc),
+ argc);
+ for (i = 0; i < argc; i++)
+ printf("%d: %s\n", i, argv[i]);
+
+ printf(_("Your current working directory:\n<top-level>%s%s\n"),
+ prefix ? "/" : "", prefix ? prefix : "");
+
+----
+
+Build and try it. As you may expect, there's pretty much just whatever we give
+on the command line, including the name of our command. (If `prefix` is empty
+for you, try `cd Documentation/ && ../bin-wrappers/git psuh`). That's not so
+helpful. So what other context can we get?
+
+Add a line to `#include "config.h"`. Then, add the following bits to the
+function body:
+
+----
+ const char *cfg_name;
+
+...
+
+ git_config(git_default_config, NULL);
+ if (git_config_get_string_const("user.name", &cfg_name) > 0)
+ printf(_("No name is found in config\n"));
+ else
+ printf(_("Your name: %s\n"), cfg_name);
+----
+
+`git_config()` will grab the configuration from config files known to Git and
+apply standard precedence rules. `git_config_get_string_const()` will look up
+a specific key ("user.name") and give you the value. There are a number of
+single-key lookup functions like this one; you can see them all (and more info
+about how to use `git_config()`) in `Documentation/technical/api-config.txt`.
+
+You should see that the name printed matches the one you see when you run:
+
+----
+$ git config --get user.name
+----
+
+Great! Now we know how to check for values in the Git config. Let's commit this
+too, so we don't lose our progress.
+
+----
+$ git add builtin/psuh.c
+$ git commit -sm "psuh: show parameters & config opts"
+----
+
+NOTE: Again, the above is for sake of brevity in this tutorial. In a real change
+you should not use `-m` but instead use the editor to write a meaningful
+message.
+
+Still, it'd be nice to know what the user's working context is like. Let's see
+if we can print the name of the user's current branch. We can mimic the
+`git status` implementation; the printer is located in `wt-status.c` and we can
+see that the branch is held in a `struct wt_status`.
+
+`wt_status_print()` gets invoked by `cmd_status()` in `builtin/commit.c`.
+Looking at that implementation we see the status config being populated like so:
+
+----
+status_init_config(&s, git_status_config);
+----
+
+But as we drill down, we can find that `status_init_config()` wraps a call
+to `git_config()`. Let's modify the code we wrote in the previous commit.
+
+Be sure to include the header to allow you to use `struct wt_status`:
+----
+#include "wt-status.h"
+----
+
+Then modify your `cmd_psuh` implementation to declare your `struct wt_status`,
+prepare it, and print its contents:
+
+----
+ struct wt_status status;
+
+...
+
+ wt_status_prepare(the_repository, &status);
+ git_config(git_default_config, &status);
+
+...
+
+ printf(_("Your current branch: %s\n"), status.branch);
+----
+
+Run it again. Check it out - here's the (verbose) name of your current branch!
+
+Let's commit this as well.
+
+----
+$ git add builtin/psuh.c
+$ git commit -sm "psuh: print the current branch"
+----
+
+Now let's see if we can get some info about a specific commit.
+
+Luckily, there are some helpers for us here. `commit.h` has a function called
+`lookup_commit_reference_by_name` to which we can simply provide a hardcoded
+string; `pretty.h` has an extremely handy `pp_commit_easy()` call which doesn't
+require a full format object to be passed.
+
+Add the following includes:
+
+----
+#include "commit.h"
+#include "pretty.h"
+----
+
+Then, add the following lines within your implementation of `cmd_psuh()` near
+the declarations and the logic, respectively.
+
+----
+ struct commit *c = NULL;
+ struct strbuf commitline = STRBUF_INIT;
+
+...
+
+ c = lookup_commit_reference_by_name("origin/master");
+
+ if (c != NULL) {
+ pp_commit_easy(CMIT_FMT_ONELINE, c, &commitline);
+ printf(_("Current commit: %s\n"), commitline.buf);
+ }
+----
+
+The `struct strbuf` provides some safety belts to your basic `char*`, one of
+which is a length member to prevent buffer overruns. It needs to be initialized
+nicely with `STRBUF_INIT`. Keep it in mind when you need to pass around `char*`.
+
+`lookup_commit_reference_by_name` resolves the name you pass it, so you can play
+with the value there and see what kind of things you can come up with.
+
+`pp_commit_easy` is a convenience wrapper in `pretty.h` that takes a single
+format enum shorthand, rather than an entire format struct. It then
+pretty-prints the commit according to that shorthand. These are similar to the
+formats available with `--pretty=FOO` in many Git commands.
+
+Build it and run, and if you're using the same name in the example, you should
+see the subject line of the most recent commit in `origin/master` that you know
+about. Neat! Let's commit that as well.
+
+----
+$ git add builtin/psuh.c
+$ git commit -sm "psuh: display the top of origin/master"
+----
+
+[[add-documentation]]
+=== Adding Documentation
+
+Awesome! You've got a fantastic new command that you're ready to share with the
+community. But hang on just a minute - this isn't very user-friendly. Run the
+following:
+
+----
+$ ./bin-wrappers/git help psuh
+----
+
+Your new command is undocumented! Let's fix that.
+
+Take a look at `Documentation/git-*.txt`. These are the manpages for the
+subcommands that Git knows about. You can open these up and take a look to get
+acquainted with the format, but then go ahead and make a new file
+`Documentation/git-psuh.txt`. Like with most of the documentation in the Git
+project, help pages are written with AsciiDoc (see CodingGuidelines, "Writing
+Documentation" section). Use the following template to fill out your own
+manpage:
+
+// Surprisingly difficult to embed AsciiDoc source within AsciiDoc.
+[listing]
+....
+git-psuh(1)
+===========
+
+NAME
+----
+git-psuh - Delight users' typo with a shy horse
+
+
+SYNOPSIS
+--------
+[verse]
+'git-psuh [<arg>...]'
+
+DESCRIPTION
+-----------
+...
+
+OPTIONS[[OPTIONS]]
+------------------
+...
+
+OUTPUT
+------
+...
+
+GIT
+---
+Part of the linkgit:git[1] suite
+....
+
+The most important pieces of this to note are the file header, underlined by =,
+the NAME section, and the SYNOPSIS, which would normally contain the grammar if
+your command took arguments. Try to use well-established manpage headers so your
+documentation is consistent with other Git and UNIX manpages; this makes life
+easier for your user, who can skip to the section they know contains the
+information they need.
+
+Now that you've written your manpage, you'll need to build it explicitly. We
+convert your AsciiDoc to troff which is man-readable like so:
+
+----
+$ make all doc
+$ man Documentation/git-psuh.1
+----
+
+or
+
+----
+$ make -C Documentation/ git-psuh.1
+$ man Documentation/git-psuh.1
+----
+
+NOTE: You may need to install the package `asciidoc` to get this to work.
+
+While this isn't as satisfying as running through `git help`, you can at least
+check that your help page looks right.
+
+You can also check that the documentation coverage is good (that is, the project
+sees that your command has been implemented as well as documented) by running
+`make check-docs` from the top-level.
+
+Go ahead and commit your new documentation change.
+
+[[add-usage]]
+=== Adding Usage Text
+
+Try and run `./bin-wrappers/git psuh -h`. Your command should crash at the end.
+That's because `-h` is a special case which your command should handle by
+printing usage.
+
+Take a look at `Documentation/technical/api-parse-options.txt`. This is a handy
+tool for pulling out options you need to be able to handle, and it takes a
+usage string.
+
+In order to use it, we'll need to prepare a NULL-terminated array of usage
+strings and a `builtin_psuh_options` array.
+
+Add a line to `#include "parse-options.h"`.
+
+At global scope, add your array of usage strings:
+
+----
+static const char * const psuh_usage[] = {
+ N_("git psuh [<arg>...]"),
+ NULL,
+};
+----
+
+Then, within your `cmd_psuh()` implementation, we can declare and populate our
+`option` struct. Ours is pretty boring but you can add more to it if you want to
+explore `parse_options()` in more detail:
+
+----
+ struct option options[] = {
+ OPT_END()
+ };
+----
+
+Finally, before you print your args and prefix, add the call to
+`parse-options()`:
+
+----
+ argc = parse_options(argc, argv, prefix, options, psuh_usage, 0);
+----
+
+This call will modify your `argv` parameter. It will strip the options you
+specified in `options` from `argv` and the locations pointed to from `options`
+entries will be updated. Be sure to replace your `argc` with the result from
+`parse_options()`, or you will be confused if you try to parse `argv` later.
+
+It's worth noting the special argument `--`. As you may be aware, many Unix
+commands use `--` to indicate "end of named parameters" - all parameters after
+the `--` are interpreted merely as positional arguments. (This can be handy if
+you want to pass as a parameter something which would usually be interpreted as
+a flag.) `parse_options()` will terminate parsing when it reaches `--` and give
+you the rest of the options afterwards, untouched.
+
+Build again. Now, when you run with `-h`, you should see your usage printed and
+your command terminated before anything else interesting happens. Great!
+
+Go ahead and commit this one, too.
+
+[[testing]]
+== Testing
+
+It's important to test your code - even for a little toy command like this one.
+Moreover, your patch won't be accepted into the Git tree without tests. Your
+tests should:
+
+* Illustrate the current behavior of the feature
+* Prove the current behavior matches the expected behavior
+* Ensure the externally-visible behavior isn't broken in later changes
+
+So let's write some tests.
+
+Related reading: `t/README`
+
+[[overview-test-structure]]
+=== Overview of Testing Structure
+
+The tests in Git live in `t/` and are named with a 4-digit decimal number using
+the schema shown in the Naming Tests section of `t/README`.
+
+[[write-new-test]]
+=== Writing Your Test
+
+Since this a toy command, let's go ahead and name the test with t9999. However,
+as many of the family/subcmd combinations are full, best practice seems to be
+to find a command close enough to the one you've added and share its naming
+space.
+
+Create a new file `t/t9999-psuh-tutorial.sh`. Begin with the header as so (see
+"Writing Tests" and "Source 'test-lib.sh'" in `t/README`):
+
+----
+#!/bin/sh
+
+test_description='git-psuh test
+
+This test runs git-psuh and makes sure it does not crash.'
+
+. ./test-lib.sh
+----
+
+Tests are framed inside of a `test_expect_success` in order to output TAP
+formatted results. Let's make sure that `git psuh` doesn't exit poorly and does
+mention the right animal somewhere:
+
+----
+test_expect_success 'runs correctly with no args and good output' '
+ git psuh >actual &&
+ test_i18ngrep Pony actual
+'
+----
+
+Indicate that you've run everything you wanted by adding the following at the
+bottom of your script:
+
+----
+test_done
+----
+
+Make sure you mark your test script executable:
+
+----
+$ chmod +x t/t9999-psuh-tutorial.sh
+----
+
+You can get an idea of whether you created your new test script successfully
+by running `make -C t test-lint`, which will check for things like test number
+uniqueness, executable bit, and so on.
+
+[[local-test]]
+=== Running Locally
+
+Let's try and run locally:
+
+----
+$ make
+$ cd t/ && prove t9999-psuh-tutorial.sh
+----
+
+You can run the full test suite and ensure `git-psuh` didn't break anything:
+
+----
+$ cd t/
+$ prove -j$(nproc) --shuffle t[0-9]*.sh
+----
+
+NOTE: You can also do this with `make test` or use any testing harness which can
+speak TAP. `prove` can run concurrently. `shuffle` randomizes the order the
+tests are run in, which makes them resilient against unwanted inter-test
+dependencies. `prove` also makes the output nicer.
+
+Go ahead and commit this change, as well.
+
+[[ready-to-share]]
+== Getting Ready to Share
+
+You may have noticed already that the Git project performs its code reviews via
+emailed patches, which are then applied by the maintainer when they are ready
+and approved by the community. The Git project does not accept patches from
+pull requests, and the patches emailed for review need to be formatted a
+specific way. At this point the tutorial diverges, in order to demonstrate two
+different methods of formatting your patchset and getting it reviewed.
+
+The first method to be covered is GitGitGadget, which is useful for those
+already familiar with GitHub's common pull request workflow. This method
+requires a GitHub account.
+
+The second method to be covered is `git send-email`, which can give slightly
+more fine-grained control over the emails to be sent. This method requires some
+setup which can change depending on your system and will not be covered in this
+tutorial.
+
+Regardless of which method you choose, your engagement with reviewers will be
+the same; the review process will be covered after the sections on GitGitGadget
+and `git send-email`.
+
+[[howto-ggg]]
+== Sending Patches via GitGitGadget
+
+One option for sending patches is to follow a typical pull request workflow and
+send your patches out via GitGitGadget. GitGitGadget is a tool created by
+Johannes Schindelin to make life as a Git contributor easier for those used to
+the GitHub PR workflow. It allows contributors to open pull requests against its
+mirror of the Git project, and does some magic to turn the PR into a set of
+emails and send them out for you. It also runs the Git continuous integration
+suite for you. It's documented at http://gitgitgadget.github.io.
+
+[[create-fork]]
+=== Forking `git/git` on GitHub
+
+Before you can send your patch off to be reviewed using GitGitGadget, you will
+need to fork the Git project and upload your changes. First thing - make sure
+you have a GitHub account.
+
+Head to the https://github.com/git/git[GitHub mirror] and look for the Fork
+button. Place your fork wherever you deem appropriate and create it.
+
+[[upload-to-fork]]
+=== Uploading to Your Own Fork
+
+To upload your branch to your own fork, you'll need to add the new fork as a
+remote. You can use `git remote -v` to show the remotes you have added already.
+From your new fork's page on GitHub, you can press "Clone or download" to get
+the URL; then you need to run the following to add, replacing your own URL and
+remote name for the examples provided:
+
+----
+$ git remote add remotename git@github.com:remotename/git.git
+----
+
+or to use the HTTPS URL:
+
+----
+$ git remote add remotename https://github.com/remotename/git/.git
+----
+
+Run `git remote -v` again and you should see the new remote showing up.
+`git fetch remotename` (with the real name of your remote replaced) in order to
+get ready to push.
+
+Next, double-check that you've been doing all your development in a new branch
+by running `git branch`. If you didn't, now is a good time to move your new
+commits to their own branch.
+
+As mentioned briefly at the beginning of this document, we are basing our work
+on `master`, so go ahead and update as shown below, or using your preferred
+workflow.
+
+----
+$ git checkout master
+$ git pull -r
+$ git rebase master psuh
+----
+
+Finally, you're ready to push your new topic branch! (Due to our branch and
+command name choices, be careful when you type the command below.)
+
+----
+$ git push remotename psuh
+----
+
+Now you should be able to go and check out your newly created branch on GitHub.
+
+[[send-pr-ggg]]
+=== Sending a PR to GitGitGadget
+
+In order to have your code tested and formatted for review, you need to start by
+opening a Pull Request against `gitgitgadget/git`. Head to
+https://github.com/gitgitgadget/git and open a PR either with the "New pull
+request" button or the convenient "Compare & pull request" button that may
+appear with the name of your newly pushed branch.
+
+Review the PR's title and description, as it's used by GitGitGadget as the cover
+letter for your change. When you're happy, submit your pull request.
+
+[[run-ci-ggg]]
+=== Running CI and Getting Ready to Send
+
+If it's your first time using GitGitGadget (which is likely, as you're using
+this tutorial) then someone will need to give you permission to use the tool.
+As mentioned in the GitGitGadget documentation, you just need someone who
+already uses it to comment on your PR with `/allow <username>`. GitGitGadget
+will automatically run your PRs through the CI even without the permission given
+but you will not be able to `/submit` your changes until someone allows you to
+use the tool.
+
+If the CI fails, you can update your changes with `git rebase -i` and push your
+branch again:
+
+----
+$ git push -f remotename psuh
+----
+
+In fact, you should continue to make changes this way up until the point when
+your patch is accepted into `next`.
+
+////
+TODO https://github.com/gitgitgadget/gitgitgadget/issues/83
+It'd be nice to be able to verify that the patch looks good before sending it
+to everyone on Git mailing list.
+[[check-work-ggg]]
+=== Check Your Work
+////
+
+[[send-mail-ggg]]
+=== Sending Your Patches
+
+Now that your CI is passing and someone has granted you permission to use
+GitGitGadget with the `/allow` command, sending out for review is as simple as
+commenting on your PR with `/submit`.
+
+[[responding-ggg]]
+=== Updating With Comments
+
+Skip ahead to <<reviewing,Responding to Reviews>> for information on how to
+reply to review comments you will receive on the mailing list.
+
+Once you have your branch again in the shape you want following all review
+comments, you can submit again:
+
+----
+$ git push -f remotename psuh
+----
+
+Next, go look at your pull request against GitGitGadget; you should see the CI
+has been kicked off again. Now while the CI is running is a good time for you
+to modify your description at the top of the pull request thread; it will be
+used again as the cover letter. You should use this space to describe what
+has changed since your previous version, so that your reviewers have some idea
+of what they're looking at. When the CI is done running, you can comment once
+more with `/submit` - GitGitGadget will automatically add a v2 mark to your
+changes.
+
+[[howto-git-send-email]]
+== Sending Patches with `git send-email`
+
+If you don't want to use GitGitGadget, you can also use Git itself to mail your
+patches. Some benefits of using Git this way include finer grained control of
+subject line (for example, being able to use the tag [RFC PATCH] in the subject)
+and being able to send a ``dry run'' mail to yourself to ensure it all looks
+good before going out to the list.
+
+[[setup-git-send-email]]
+=== Prerequisite: Setting Up `git send-email`
+
+Configuration for `send-email` can vary based on your operating system and email
+provider, and so will not be covered in this tutorial, beyond stating that in
+many distributions of Linux, `git-send-email` is not packaged alongside the
+typical `git` install. You may need to install this additional package; there
+are a number of resources online to help you do so. You will also need to
+determine the right way to configure it to use your SMTP server; again, as this
+configuration can change significantly based on your system and email setup, it
+is out of scope for the context of this tutorial.
+
+[[format-patch]]
+=== Preparing Initial Patchset
+
+Sending emails with Git is a two-part process; before you can prepare the emails
+themselves, you'll need to prepare the patches. Luckily, this is pretty simple:
+
+----
+$ git format-patch --cover-letter -o psuh/ master..psuh
+----
+
+The `--cover-letter` parameter tells `format-patch` to create a cover letter
+template for you. You will need to fill in the template before you're ready
+to send - but for now, the template will be next to your other patches.
+
+The `-o psuh/` parameter tells `format-patch` to place the patch files into a
+directory. This is useful because `git send-email` can take a directory and
+send out all the patches from there.
+
+`master..psuh` tells `format-patch` to generate patches for the difference
+between `master` and `psuh`. It will make one patch file per commit. After you
+run, you can go have a look at each of the patches with your favorite text
+editor and make sure everything looks alright; however, it's not recommended to
+make code fixups via the patch file. It's a better idea to make the change the
+normal way using `git rebase -i` or by adding a new commit than by modifying a
+patch.
+
+NOTE: Optionally, you can also use the `--rfc` flag to prefix your patch subject
+with ``[RFC PATCH]'' instead of ``[PATCH]''. RFC stands for ``request for
+comments'' and indicates that while your code isn't quite ready for submission,
+you'd like to begin the code review process. This can also be used when your
+patch is a proposal, but you aren't sure whether the community wants to solve
+the problem with that approach or not - to conduct a sort of design review. You
+may also see on the list patches marked ``WIP'' - this means they are incomplete
+but want reviewers to look at what they have so far. You can add this flag with
+`--subject-prefix=WIP`.
+
+Check and make sure that your patches and cover letter template exist in the
+directory you specified - you're nearly ready to send out your review!
+
+[[cover-letter]]
+=== Preparing Email
+
+In addition to an email per patch, the Git community also expects your patches
+to come with a cover letter, typically with a subject line [PATCH 0/x] (where
+x is the number of patches you're sending). Since you invoked `format-patch`
+with `--cover-letter`, you've already got a template ready. Open it up in your
+favorite editor.
+
+You should see a number of headers present already. Check that your `From:`
+header is correct. Then modify your `Subject:` to something which succinctly
+covers the purpose of your entire topic branch, for example:
+
+----
+Subject: [PATCH 0/7] adding the 'psuh' command
+----
+
+Make sure you retain the ``[PATCH 0/X]'' part; that's what indicates to the Git
+community that this email is the beginning of a review, and many reviewers
+filter their email for this type of flag.
+
+You'll need to add some extra parameters when you invoke `git send-email` to add
+the cover letter.
+
+Next you'll have to fill out the body of your cover letter. This is an important
+component of change submission as it explains to the community from a high level
+what you're trying to do, and why, in a way that's more apparent than just
+looking at your diff. Be sure to explain anything your diff doesn't make clear
+on its own.
+
+Here's an example body for `psuh`:
+
+----
+Our internal metrics indicate widespread interest in the command
+git-psuh - that is, many users are trying to use it, but finding it is
+unavailable, using some unknown workaround instead.
+
+The following handful of patches add the psuh command and implement some
+handy features on top of it.
+
+This patchset is part of the MyFirstContribution tutorial and should not
+be merged.
+----
+
+The template created by `git format-patch --cover-letter` includes a diffstat.
+This gives reviewers a summary of what they're in for when reviewing your topic.
+The one generated for `psuh` from the sample implementation looks like this:
+
+----
+ Documentation/git-psuh.txt | 40 +++++++++++++++++++++
+ Makefile | 1 +
+ builtin.h | 1 +
+ builtin/psuh.c | 73 ++++++++++++++++++++++++++++++++++++++
+ git.c | 1 +
+ t/t9999-psuh-tutorial.sh | 12 +++++++
+ 6 files changed, 128 insertions(+)
+ create mode 100644 Documentation/git-psuh.txt
+ create mode 100644 builtin/psuh.c
+ create mode 100755 t/t9999-psuh-tutorial.sh
+----
+
+Finally, the letter will include the version of Git used to generate the
+patches. You can leave that string alone.
+
+[[sending-git-send-email]]
+=== Sending Email
+
+At this point you should have a directory `psuh/` which is filled with your
+patches and a cover letter. Time to mail it out! You can send it like this:
+
+----
+$ git send-email --to=target@example.com psuh/*.patch
+----
+
+NOTE: Check `git help send-email` for some other options which you may find
+valuable, such as changing the Reply-to address or adding more CC and BCC lines.
+
+NOTE: When you are sending a real patch, it will go to git@vger.kernel.org - but
+please don't send your patchset from the tutorial to the real mailing list! For
+now, you can send it to yourself, to make sure you understand how it will look.
+
+After you run the command above, you will be presented with an interactive
+prompt for each patch that's about to go out. This gives you one last chance to
+edit or quit sending something (but again, don't edit code this way). Once you
+press `y` or `a` at these prompts your emails will be sent! Congratulations!
+
+Awesome, now the community will drop everything and review your changes. (Just
+kidding - be patient!)
+
+[[v2-git-send-email]]
+=== Sending v2
+
+Skip ahead to <<reviewing,Responding to Reviews>> for information on how to
+handle comments from reviewers. Continue this section when your topic branch is
+shaped the way you want it to look for your patchset v2.
+
+When you're ready with the next iteration of your patch, the process is fairly
+similar.
+
+First, generate your v2 patches again:
+
+----
+$ git format-patch -v2 --cover-letter -o psuh/ master..psuh
+----
+
+This will add your v2 patches, all named like `v2-000n-my-commit-subject.patch`,
+to the `psuh/` directory. You may notice that they are sitting alongside the v1
+patches; that's fine, but be careful when you are ready to send them.
+
+Edit your cover letter again. Now is a good time to mention what's different
+between your last version and now, if it's something significant. You do not
+need the exact same body in your second cover letter; focus on explaining to
+reviewers the changes you've made that may not be as visible.
+
+You will also need to go and find the Message-Id of your previous cover letter.
+You can either note it when you send the first series, from the output of `git
+send-email`, or you can look it up on the
+https://public-inbox.org/git[mailing list]. Find your cover letter in the
+archives, click on it, then click "permalink" or "raw" to reveal the Message-Id
+header. It should match:
+
+----
+Message-Id: <foo.12345.author@example.com>
+----
+
+Your Message-Id is `<foo.12345.author@example.com>`. This example will be used
+below as well; make sure to replace it with the correct Message-Id for your
+**previous cover letter** - that is, if you're sending v2, use the Message-Id
+from v1; if you're sending v3, use the Message-Id from v2.
+
+While you're looking at the email, you should also note who is CC'd, as it's
+common practice in the mailing list to keep all CCs on a thread. You can add
+these CC lines directly to your cover letter with a line like so in the header
+(before the Subject line):
+
+----
+CC: author@example.com, Othe R <other@example.com>
+----
+
+Now send the emails again, paying close attention to which messages you pass in
+to the command:
+
+----
+$ git send-email --to=target@example.com
+ --in-reply-to="<foo.12345.author@example.com>"
+ psuh/v2*
+----
+
+[[single-patch]]
+=== Bonus Chapter: One-Patch Changes
+
+In some cases, your very small change may consist of only one patch. When that
+happens, you only need to send one email. Your commit message should already be
+meaningful and explain at a high level the purpose (what is happening and why)
+of your patch, but if you need to supply even more context, you can do so below
+the `---` in your patch. Take the example below, which was generated with `git
+format-patch` on a single commit, and then edited to add the content between
+the `---` and the diffstat.
+

+
+[[now-what]]
+== My Patch Got Emailed - Now What?
+
+[[reviewing]]
+=== Responding to Reviews
+
+After a few days, you will hopefully receive a reply to your patchset with some
+comments. Woohoo! Now you can get back to work.
+
+It's good manners to reply to each comment, notifying the reviewer that you have
+made the change requested, feel the original is better, or that the comment
+inspired you to do something a new way which is superior to both the original
+and the suggested change. This way reviewers don't need to inspect your v2 to
+figure out whether you implemented their comment or not.
+
+If you are going to push back on a comment, be polite and explain why you feel
+your original is better; be prepared that the reviewer may still disagree with
+you, and the rest of the community may weigh in on one side or the other. As
+with all code reviews, it's important to keep an open mind to doing something a
+different way than you originally planned; other reviewers have a different
+perspective on the project than you do, and may be thinking of a valid side
+effect which had not occurred to you. It is always okay to ask for clarification
+if you aren't sure why a change was suggested, or what the reviewer is asking
+you to do.
+
+Make sure your email client has a plaintext email mode and it is turned on; the
+Git list rejects HTML email. Please also follow the mailing list etiquette
+outlined in the
+https://kernel.googlesource.com/pub/scm/git/git/+/todo/MaintNotes[Maintainer's
+Note], which are similar to etiquette rules in most open source communities
+surrounding bottom-posting and inline replies.
+
+When you're making changes to your code, it is cleanest - that is, the resulting
+commits are easiest to look at - if you use `git rebase -i` (interactive
+rebase). Take a look at this
+https://www.oreilly.com/library/view/git-pocket-guide/9781449327507/ch10.html[overview]
+from O'Reilly. The general idea is to modify each commit which requires changes;
+this way, instead of having a patch A with a mistake, a patch B which was fine
+and required no upstream reviews in v1, and a patch C which fixes patch A for
+v2, you can just ship a v2 with a correct patch A and correct patch B. This is
+changing history, but since it's local history which you haven't shared with
+anyone, that is okay for now! (Later, it may not make sense to do this; take a
+look at the section below this one for some context.)
+
+[[after-approval]]
+=== After Review Approval
+
+The Git project has four integration branches: `pu`, `next`, `master`, and
+`maint`. Your change will be placed into `pu` fairly early on by the maintainer
+while it is still in the review process; from there, when it is ready for wider
+testing, it will be merged into `next`. Plenty of early testers use `next` and
+may report issues. Eventually, changes in `next` will make it to `master`,
+which is typically considered stable. Finally, when a new release is cut,
+`maint` is used to base bugfixes onto. As mentioned at the beginning of this
+document, you can read `Documents/SubmittingPatches` for some more info about
+the use of the various integration branches.
+
+Back to now: your code has been lauded by the upstream reviewers. It is perfect.
+It is ready to be accepted. You don't need to do anything else; the maintainer
+will merge your topic branch to `next` and life is good.
+
+However, if you discover it isn't so perfect after this point, you may need to
+take some special steps depending on where you are in the process.
+
+If the maintainer has announced in the "What's cooking in git.git" email that
+your topic is marked for `next` - that is, that they plan to merge it to `next`
+but have not yet done so - you should send an email asking the maintainer to
+wait a little longer: "I've sent v4 of my series and you marked it for `next`,
+but I need to change this and that - please wait for v5 before you merge it."
+
+If the topic has already been merged to `next`, rather than modifying your
+patches with `git rebase -i`, you should make further changes incrementally -
+that is, with another commit, based on top of the maintainer's topic branch as
+detailed in https://github.com/gitster/git. Your work is still in the same topic
+but is now incremental, rather than a wholesale rewrite of the topic branch.
+
+The topic branches in the maintainer's GitHub are mirrored in GitGitGadget, so
+if you're sending your reviews out that way, you should be sure to open your PR
+against the appropriate GitGitGadget/Git branch.
+
+If you're using `git send-email`, you can use it the same way as before, but you
+should generate your diffs from `<topic>..<mybranch>` and base your work on
+`<topic>` instead of `master`.

+Git 2.23 Release Notes
+======================
+
+Updates since v2.22
+-------------------
+
+Backward compatibility note
+
+ * The "--base" option of "format-patch" computed the patch-ids for
+ prerequisite patches in an unstable way, which has been updated to
+ compute in a way that is compatible with "git patch-id --stable".
+
+ * The "git log" command by default behaves as if the --mailmap option
+ was given.
+
+
+UI, Workflows & Features
+
+ * The "git fast-export/import" pair has been taught to handle commits
+ with log messages in encoding other than UTF-8 better.
+
+ * In recent versions of Git, per-worktree refs are exposed in
+ refs/worktrees/<wtname>/ hierarchy, which means that worktree names
+ must be a valid refname component. The code now sanitizes the names
+ given to worktrees, to make sure these refs are well-formed.
+
+ * "git merge" learned "--quit" option that cleans up the in-progress
+ merge while leaving the working tree and the index still in a mess.
+
+ * "git format-patch" learns a configuration to set the default for
+ its --notes=<ref> option.
+
+ * The code to show args with potential typo that cannot be
+ interpreted as a commit-ish has been improved.
+
+ * "git clone --recurse-submodules" learned to set up the submodules
+ to ignore commit object names recorded in the superproject gitlink
+ and instead use the commits that happen to be at the tip of the
+ remote-tracking branches from the get-go, by passing the new
+ "--remote-submodules" option.
+
+ * The pattern "git diff/grep" use to extract funcname and words
+ boundary for Matlab has been extend to cover Octave, which is more
+ or less equivalent.
+
+ * "git help git" was hard to discover (well, at least for some
+ people).
+
+ * The pattern "git diff/grep" use to extract funcname and words
+ boundary for Rust has been added.
+
+ * "git status" can be told a non-standard default value for the
+ "--[no-]ahead-behind" option with a new configuration variable
+ status.aheadBehind.
+
+ * "git fetch" and "git pull" reports when a fetch results in
+ non-fast-forward updates to let the user notice unusual situation.
+ The commands learned "--no-show-forced-updates" option to disable
+ this safety feature.
+
+ * Two new commands "git switch" and "git restore" are introduced to
+ split "checking out a branch to work on advancing its history" and
+ "checking out paths out of the index and/or a tree-ish to work on
+ advancing the current history" out of the single "git checkout"
+ command.
+
+ * "git branch --list" learned to always output the detached HEAD as
+ the first item (when the HEAD is detached, of course), regardless
+ of the locale.
+
+ * The conditional inclusion mechanism learned to base the choice on
+ the branch the HEAD currently is on.
+
+ * "git rev-list --objects" learned the "--no-object-names" option to
+ squelch the path to the object that is used as a grouping hint for
+ pack-objects.
+
+ * A new tag.gpgSign configuration variable turns "git tag -a" into
+ "git tag -s".
+
+ * "git multi-pack-index" learned expire and repack subcommands.
+
+ * "git blame" learned to "ignore" commits in the history, whose
+ effects (as well as their presence) get ignored.
+
+ * "git cherry-pick/revert" learned a new "--skip" action.
+
+ * The tips of refs from the alternate object store can be used as
+ starting point for reachability computation now.
+
+ * Extra blank lines in "git status" output have been reduced.
+
+ * The commits in a repository can be described by multiple
+ commit-graph files now, which allows the commit-graph files to be
+ updated incrementally.
+
+ * "git range-diff" output has been tweaked for easier identification
+ of which part of what file the patch shown is about.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Update supporting parts of "git rebase" to remove code that should
+ no longer be used.
+
+ * Developer support to emulate unsatisfied prerequisites in tests to
+ ensure that the remainder of the tests still succeeds when tests
+ with prerequisites are skipped.
+
+ * "git update-server-info" learned not to rewrite the file with the
+ same contents.
+
+ * The way of specifying the path to find dynamic libraries at runtime
+ has been simplified. The old default to pass -R/path/to/dir has been
+ replaced with the new default to pass -Wl,-rpath,/path/to/dir,
+ which is the more recent GCC uses. Those who need to build with an
+ old GCC can still use "CC_LD_DYNPATH=-R"
+
+ * Prepare use of reachability index in topological walker that works
+ on a range (A..B).
+
+ * A new tutorial targeting specifically aspiring git-core
+ developers has been added.
+
+ * Auto-detect how to tell HP-UX aCC where to use dynamically linked
+ libraries from at runtime.
+
+ * "git mergetool" and its tests now spawn fewer subprocesses.
+
+ * Dev support update to help tracing out tests.
+
+ * Support to build with MSVC has been updated.
+
+ * "git fetch" that grabs from a group of remotes learned to run the
+ auto-gc only once at the very end.
+
+ * A handful of Windows build patches have been upstreamed.
+
+ * The code to read state files used by the sequencer machinery for
+ "git status" has been made more robust against a corrupt or stale
+ state files.
+
+ * "git for-each-ref" with multiple patterns have been optimized.
+
+ * The tree-walk API learned to pass an in-core repository
+ instance throughout more codepaths.
+
+ * When one step in multi step cherry-pick or revert is reset or
+ committed, the command line prompt script failed to notice the
+ current status, which has been improved.
+
+ * Many GIT_TEST_* environment variables control various aspects of
+ how our tests are run, but a few followed "non-empty is true, empty
+ or unset is false" while others followed the usual "there are a few
+ ways to spell true, like yes, on, etc., and also ways to spell
+ false, like no, off, etc." convention.
+
+ * Adjust the dir-iterator API and apply it to the local clone
+ optimization codepath.
+
+ * We have been trying out a few language features outside c89; the
+ coding guidelines document did not talk about them and instead had
+ a blanket ban against them.
+
+ * A test helper has been introduced to optimize preparation of test
+ repositories with many simple commits, and a handful of test
+ scripts have been updated to use it.
+
+
+Fixes since v2.22
+-----------------
+
+ * A relative pathname given to "git init --template=<path> <repo>"
+ ought to be relative to the directory "git init" gets invoked in,
+ but it instead was made relative to the repository, which has been
+ corrected.
+
+ * "git worktree add" used to fail when another worktree connected to
+ the same repository was corrupt, which has been corrected.
+
+ * The ownership rule for the file descriptor to fast-import remote
+ backend was mixed up, leading to an unrelated file descriptor getting
+ closed, which has been fixed.
+
+ * A "merge -c" instruction during "git rebase --rebase-merges" should
+ give the user a chance to edit the log message, even when there is
+ otherwise no need to create a new merge and replace the existing
+ one (i.e. fast-forward instead), but did not. Which has been
+ corrected.
+
+ * Code cleanup and futureproof.
+
+ * More parameter validation.
+
+ * "git update-server-info" used to leave stale packfiles in its
+ output, which has been corrected.
+
+ * The server side support for "git fetch" used to show incorrect
+ value for the HEAD symbolic ref when the namespace feature is in
+ use, which has been corrected.
+
+ * "git am -i --resolved" segfaulted after trying to see a commit as
+ if it were a tree, which has been corrected.
+

+NAME

+git-restore - Restore working tree files
+
+SYNOPSIS
+--------
+[verse]
+'git restore' [<options>] [--source=<tree>] [--staged] [--worktree] <pathspec>...
+'git restore' (-p|--patch) [<options>] [--source=<tree>] [--staged] [--worktree] [<pathspec>...]
+
+DESCRIPTION
+-----------
+Restore specified paths in the working tree with some contents from a
+restore source. If a path is tracked but does not exist in the restore
+source, it will be removed to match the source.
+
+The command can also be used to restore the content in the index with
+`--staged`, or restore both the working tree and the index with
+`--staged --worktree`.
+
+By default, the restore sources for working tree and the index are the
+index and `HEAD` respectively. `--source` could be used to specify a
+commit as the restore source.
+
+See "Reset, restore and revert" in linkgit:git[1] for the differences
+between the three commands.
+
+THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOR MAY CHANGE.
+
+OPTIONS
+-------
+-s <tree>::
+--source=<tree>::
+ Restore the working tree files with the content from the given
+ tree. It is common to specify the source tree by naming a
+ commit, branch or tag associated with it.
++
+If not specified, the default restore source for the working tree is
+the index, and the default restore source for the index is
+`HEAD`. When both `--staged` and `--worktree` are specified,
+`--source` must also be specified.
+
+-p::
+--patch::
+ Interactively select hunks in the difference between the
+ restore source and the restore location. See the ``Interactive
+ Mode'' section of linkgit:git-add[1] to learn how to operate
+ the `--patch` mode.
++
+Note that `--patch` can accept no pathspec and will prompt to restore
+all modified paths.
+
+-W::
+--worktree::
+-S::
+--staged::
+ Specify the restore location. If neither option is specified,
+ by default the working tree is restored. Specifying `--staged`
+ will only restore the index. Specifying both restores both.
+
+-q::
+--quiet::
+ Quiet, suppress feedback messages. Implies `--no-progress`.
+
+--progress::
+--no-progress::
+ Progress status is reported on the standard error stream
+ by default when it is attached to a terminal, unless `--quiet`
+ is specified. This flag enables progress reporting even if not
+ attached to a terminal, regardless of `--quiet`.
+
+--ours::
+--theirs::
+ When restoring files in the working tree from the index, use
+ stage #2 ('ours') or #3 ('theirs') for unmerged paths.
++
+Note that during `git rebase` and `git pull --rebase`, 'ours' and
+'theirs' may appear swapped. See the explanation of the same options
+in linkgit:git-checkout[1] for details.
+
+-m::
+--merge::
+ When restoring files on the working tree from the index,
+ recreate the conflicted merge in the unmerged paths.
+
+--conflict=<style>::
+ The same as `--merge` option above, but changes the way the
+ conflicting hunks are presented, overriding the
+ `merge.conflictStyle` configuration variable. Possible values
+ are "merge" (default) and "diff3" (in addition to what is
+ shown by "merge" style, shows the original contents).
+
+--ignore-unmerged::
+ When restoring files on the working tree from the index, do
+ not abort the operation if there are unmerged entries and
+ neither `--ours`, `--theirs`, `--merge` or `--conflict` is
+ specified. Unmerged paths on the working tree are left alone.
+
+--ignore-skip-worktree-bits::
+ In sparse checkout mode, by default is to only update entries
+ matched by `<pathspec>` and sparse patterns in
+ $GIT_DIR/info/sparse-checkout. This option ignores the sparse
+ patterns and unconditionally restores any files in
+ `<pathspec>`.
+
+--overlay::
+--no-overlay::
+ In overlay mode, the command never removes files when
+ restoring. In no-overlay mode, tracked files that do not
+ appear in the `--source` tree are removed, to make them match
+ `<tree>` exactly. The default is no-overlay mode.
+
+EXAMPLES
+--------
+
+The following sequence switches to the `master` branch, reverts the
+`Makefile` to two revisions back, deletes hello.c by mistake, and gets
+it back from the index.
+
+------------
+$ git switch master
+$ git restore --source master~2 Makefile <1>
+$ rm -f hello.c
+$ git restore hello.c <2>
+------------
+
+<1> take a file out of another commit
+<2> restore hello.c from the index
+
+If you want to restore _all_ C source files to match the version in
+the index, you can say
+
+------------
+$ git restore '*.c'
+------------
+
+Note the quotes around `*.c`. The file `hello.c` will also be
+restored, even though it is no longer in the working tree, because the
+file globbing is used to match entries in the index (not in the
+working tree by the shell).
+
+To restore all files in the current directory
+
+------------
+$ git restore .
+------------
+
+or to restore all working tree files with 'top' pathspec magic (see
+linkgit:gitglossary[7])
+
+------------
+$ git restore :/
+------------
+
+To restore a file in the index to match the version in `HEAD` (this is
+the same as using linkgit:git-reset[1])
+
+------------
+$ git restore --staged hello.c
+------------
+
+or you can restore both the index and the working tree (this the same
+as using linkgit:git-checkout[1])
+
+------------
+$ git restore --source=HEAD --staged --worktree hello.c
+------------
+
+or the short form which is more practical but less readable:
+
+------------
+$ git restore -s@ -SW hello.c

+NAME
+----
+git-switch - Switch branches
+
+SYNOPSIS
+--------
+[verse]
+'git switch' [<options>] [--no-guess] <branch>
+'git switch' [<options>] --detach [<start-point>]
+'git switch' [<options>] (-c|-C) <new-branch> [<start-point>]
+'git switch' [<options>] --orphan <new-branch>
+
+DESCRIPTION
+-----------
+Switch to a specified branch. The working tree and the index are
+updated to match the branch. All new commits will be added to the tip
+of this branch.
+
+Optionally a new branch could be created with either `-c`, `-C`,
+automatically from a remote branch of same name (see `--guess`), or
+detach the working tree from any branch with `--detach`, along with
+switching.
+
+Switching branches does not require a clean index and working tree
+(i.e. no differences compared to `HEAD`). The operation is aborted
+however if the operation leads to loss of local changes, unless told
+otherwise with `--discard-changes` or `--merge`.
+
+THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOR MAY CHANGE.
+
+OPTIONS
+-------
+<branch>::
+ Branch to switch to.
+
+<new-branch>::
+ Name for the new branch.
+
+<start-point>::
+ The starting point for the new branch. Specifying a
+ `<start-point>` allows you to create a branch based on some
+ other point in history than where HEAD currently points. (Or,
+ in the case of `--detach`, allows you to inspect and detach
+ from some other point.)
++
+You can use the `@{-N}` syntax to refer to the N-th last
+branch/commit switched to using "git switch" or "git checkout"
+operation. You may also specify `-` which is synonymous to `@{-1}`.
+This is often used to switch quickly between two branches, or to undo
+a branch switch by mistake.
++
+As a special case, you may use `A...B` as a shortcut for the merge
+base of `A` and `B` if there is exactly one merge base. You can leave
+out at most one of `A` and `B`, in which case it defaults to `HEAD`.
+
+-c <new-branch>::
+--create <new-branch>::
+ Create a new branch named `<new-branch>` starting at
+ `<start-point>` before switching to the branch. This is a
+ convenient shortcut for:
++
+------------
+$ git branch <new-branch>
+$ git switch <new-branch>
+------------
+
+-C <new-branch>::
+--force-create <new-branch>::
+ Similar to `--create` except that if `<new-branch>` already
+ exists, it will be reset to `<start-point>`. This is a
+ convenient shortcut for:
++
+------------
+$ git branch -f <new-branch>
+$ git switch <new-branch>
+------------
+
+-d::
+--detach::
+ Switch to a commit for inspection and discardable
+ experiments. See the "DETACHED HEAD" section in
+ linkgit:git-checkout[1] for details.
+
+--guess::
+--no-guess::
+ If `<branch>` is not found but there does exist a tracking
+ branch in exactly one remote (call it `<remote>`) with a
+ matching name, treat as equivalent to
++
+------------
+$ git switch -c <branch> --track <remote>/<branch>
+------------
++
+If the branch exists in multiple remotes and one of them is named by
+the `checkout.defaultRemote` configuration variable, we'll use that
+one for the purposes of disambiguation, even if the `<branch>` isn't
+unique across all remotes. Set it to e.g. `checkout.defaultRemote=origin`
+to always checkout remote branches from there if `<branch>` is
+ambiguous but exists on the 'origin' remote. See also
+`checkout.defaultRemote` in linkgit:git-config[1].
++
+`--guess` is the default behavior. Use `--no-guess` to disable it.
+
+-f::
+--force::
+ An alias for `--discard-changes`.
+
+--discard-changes::
+ Proceed even if the index or the working tree differs from
+ `HEAD`. Both the index and working tree are restored to match
+ the switching target. If `--recurse-submodules` is specified,
+ submodule content is also restored to match the switching
+ target. This is used to throw away local changes.
+
+-m::
+--merge::
+ If you have local modifications to one or more files that are
+ different between the current branch and the branch to which
+ you are switching, the command refuses to switch branches in
+ order to preserve your modifications in context. However,
+ with this option, a three-way merge between the current
+ branch, your working tree contents, and the new branch is
+ done, and you will be on the new branch.
++
+When a merge conflict happens, the index entries for conflicting
+paths are left unmerged, and you need to resolve the conflicts
+and mark the resolved paths with `git add` (or `git rm` if the merge
+should result in deletion of the path).
+
+--conflict=<style>::
+ The same as `--merge` option above, but changes the way the
+ conflicting hunks are presented, overriding the
+ `merge.conflictStyle` configuration variable. Possible values are
+ "merge" (default) and "diff3" (in addition to what is shown by
+ "merge" style, shows the original contents).
+
+-q::
+--quiet::
+ Quiet, suppress feedback messages.
+
+--progress::
+--no-progress::
+ Progress status is reported on the standard error stream
+ by default when it is attached to a terminal, unless `--quiet`
+ is specified. This flag enables progress reporting even if not
+ attached to a terminal, regardless of `--quiet`.
+
+-t::
+--track::
+ When creating a new branch, set up "upstream" configuration.
+ `-c` is implied. See `--track` in linkgit:git-branch[1] for
+ details.
++
+If no `-c` option is given, the name of the new branch will be derived
+from the remote-tracking branch, by looking at the local part of the
+refspec configured for the corresponding remote, and then stripping
+the initial part up to the "*". This would tell us to use `hack` as
+the local branch when branching off of `origin/hack` (or
+`remotes/origin/hack`, or even `refs/remotes/origin/hack`). If the
+given name has no slash, or the above guessing results in an empty
+name, the guessing is aborted. You can explicitly give a name with
+`-c` in such a case.
+
+--no-track::
+ Do not set up "upstream" configuration, even if the
+ `branch.autoSetupMerge` configuration variable is true.
+
+--orphan <new-branch>::
+ Create a new 'orphan' branch, named `<new-branch>`. All
+ tracked files are removed.
+
+--ignore-other-worktrees::
+ `git switch` refuses when the wanted ref is already
+ checked out by another worktree. This option makes it check
+ the ref out anyway. In other words, the ref can be held by
+ more than one worktree.
+
+--recurse-submodules::
+--no-recurse-submodules::
+ Using `--recurse-submodules` will update the content of all
+ initialized submodules according to the commit recorded in the
+ superproject. If nothing (or `--no-recurse-submodules`) is
+ used, the work trees of submodules will not be updated. Just
+ like linkgit:git-submodule[1], this will detach `HEAD` of the
+ submodules.
+
+EXAMPLES
+--------
+
+The following command switches to the "master" branch:
+
+------------
+$ git switch master
+------------
+
+After working in the wrong branch, switching to the correct branch
+would be done using:
+
+------------
+$ git switch mytopic
+------------
+
+However, your "wrong" branch and correct "mytopic" branch may differ
+in files that you have modified locally, in which case the above
+switch would fail like this:
+
+------------
+$ git switch mytopic
+error: You have local changes to 'frotz'; not switching branches.
+------------
+
+You can give the `-m` flag to the command, which would try a three-way
+merge:
+
+------------
+$ git switch -m mytopic
+Auto-merging frotz
+------------
+
+After this three-way merge, the local modifications are _not_
+registered in your index file, so `git diff` would show you what
+changes you made since the tip of the new branch.
+
+To switch back to the previous branch before we switched to mytopic
+(i.e. "master" branch):
+
+------------
+$ git switch -
+------------
+
+You can grow a new branch from any commit. For example, switch to
+"HEAD~3" and create branch "fixup":
+
+------------
+$ git switch -c fixup HEAD~3
+Switched to a new branch 'fixup'
+------------
+
+If you want to start a new branch from a remote branch of the same
+name:
+
+------------
+$ git switch new-topic
+Branch 'new-topic' set up to track remote branch 'new-topic' from 'origin'
+Switched to a new branch 'new-topic'
+------------
+
+To check out commit `HEAD~3` for temporary inspection or experiment
+without creating a new branch:
+
+------------
+$ git switch --detach HEAD~3
+HEAD is now at 9fc9555312 Merge branch 'cc/shared-index-permbits'
+------------
+
+If it turns out whatever you have done is worth keeping, you can
+always create a new name for it (without switching away):
+
+------------
+$ git switch -c good-surprises
+------------

+Reset, restore and revert
+~~~~~~~~~~~~~~~~~~~~~~~~~
+There are three commands with similar names: `git reset`,
+`git restore` and `git revert`.
+
+* linkgit:git-revert[1] is about making a new commit that reverts the
+ changes made by other commits.
+
+* linkgit:git-restore[1] is about restoring files in the working tree
+ from either the index or another commit. This command does not
+ update your branch. The command can also be used to restore files in
+ the index from another commit.
+
+* linkgit:git-reset[1] is about updating your branch, moving the tip
+ in order to add or remove commits from the branch. This operation
+ changes the commit history.
++
+`git reset` can also be used to restore the index, overlapping with
+`git restore`.
+
Low-level commands (plumbing)
-----------------------------
These attributes affect how the contents stored in the
repository are copied to the working tree files when commands
-such as 'git checkout' and 'git merge' run. They also affect how
+such as 'git switch', 'git checkout' and 'git merge' run.
+They also affect how
Git stores the contents you prepare in the working tree in the
repository upon 'git add' and 'git commit'.

The former lets your shell expand the fileglob, and you are asking
http://marc.info/?l=git&m=119150393620273 for further
information.
+Some other commands that also work on files in the working tree and/or
+in the index can take `--staged` and/or `--worktree`.
+
+* `--staged` is exactly like `--cached`, which is used to ask a
+ command to only work on the index, not the working tree.
+
+* `--worktree` is the opposite, to ask a command to work on the
+ working tree only, not the index.
+
+* The two options can be specified together to ask a command to work
+ on both the index and the working tree.

+Commit Graphs Chains
+--------------------
+
+Typically, repos grow with near-constant velocity (commits per day). Over time,
+the number of commits added by a fetch operation is much smaller than the
+number of commits in the full history. By creating a "chain" of commit-graphs,
+we enable fast writes of new commit data without rewriting the entire commit
+history -- at least, most of the time.
+
+## File Layout
+
+A commit-graph chain uses multiple files, and we use a fixed naming convention
+to organize these files. Each commit-graph file has a name
+`$OBJDIR/info/commit-graphs/graph-{hash}.graph` where `{hash}` is the hex-
+valued hash stored in the footer of that file (which is a hash of the file's
+contents before that hash). For a chain of commit-graph files, a plain-text
+file at `$OBJDIR/info/commit-graphs/commit-graph-chain` contains the
+hashes for the files in order from "lowest" to "highest".
+
+For example, if the `commit-graph-chain` file contains the lines
+
+```
+ {hash0}
+ {hash1}
+ {hash2}
+```
+
+then the commit-graph chain looks like the following diagram:
+
+ +-----------------------+
+ | graph-{hash2}.graph |
+ +-----------------------+
+ |
+ +-----------------------+
+ | |
+ | graph-{hash1}.graph |
+ | |
+ +-----------------------+
+ |
+ +-----------------------+
+ | |
+ | |
+ | |
+ | graph-{hash0}.graph |
+ | |
+ | |
+ | |
+ +-----------------------+
+
+Let X0 be the number of commits in `graph-{hash0}.graph`, X1 be the number of
+commits in `graph-{hash1}.graph`, and X2 be the number of commits in
+`graph-{hash2}.graph`. If a commit appears in position i in `graph-{hash2}.graph`,
+then we interpret this as being the commit in position (X0 + X1 + i), and that
+will be used as its "graph position". The commits in `graph-{hash2}.graph` use these
+positions to refer to their parents, which may be in `graph-{hash1}.graph` or
+`graph-{hash0}.graph`. We can navigate to an arbitrary commit in position j by checking
+its containment in the intervals [0, X0), [X0, X0 + X1), [X0 + X1, X0 + X1 +
+X2).
+
+Each commit-graph file (except the base, `graph-{hash0}.graph`) contains data
+specifying the hashes of all files in the lower layers. In the above example,
+`graph-{hash1}.graph` contains `{hash0}` while `graph-{hash2}.graph` contains
+`{hash0}` and `{hash1}`.
+
+## Merging commit-graph files
+
+If we only added a new commit-graph file on every write, we would run into a
+linear search problem through many commit-graph files. Instead, we use a merge
+strategy to decide when the stack should collapse some number of levels.
+
+The diagram below shows such a collapse. As a set of new commits are added, it
+is determined by the merge strategy that the files should collapse to
+`graph-{hash1}`. Thus, the new commits, the commits in `graph-{hash2}` and
+the commits in `graph-{hash1}` should be combined into a new `graph-{hash3}`
+file.
+
+ +---------------------+
+ | |
+ | (new commits) |
+ | |
+ +---------------------+
+ | |
+ +-----------------------+ +---------------------+
+ | graph-{hash2} |->| |
+ +-----------------------+ +---------------------+
+ | | |
+ +-----------------------+ +---------------------+
+ | | | |
+ | graph-{hash1} |->| |
+ | | | |
+ +-----------------------+ +---------------------+
+ | tmp_graphXXX
+ +-----------------------+
+ | |
+ | |
+ | |
+ | graph-{hash0} |
+ | |
+ | |
+ | |
+ +-----------------------+
+
+During this process, the commits to write are combined, sorted and we write the
+contents to a temporary file, all while holding a `commit-graph-chain.lock`
+lock-file. When the file is flushed, we rename it to `graph-{hash3}`
+according to the computed `{hash3}`. Finally, we write the new chain data to
+`commit-graph-chain.lock`:
+
+```
+ {hash3}
+ {hash0}
+```
+
+We then close the lock-file.
+
+## Merge Strategy
+
+When writing a set of commits that do not exist in the commit-graph stack of
+height N, we default to creating a new file at level N + 1. We then decide to
+merge with the Nth level if one of two conditions hold:
+
+ 1. `--size-multiple=<X>` is specified or X = 2, and the number of commits in
+ level N is less than X times the number of commits in level N + 1.
+
+ 2. `--max-commits=<C>` is specified with non-zero C and the number of commits
+ in level N + 1 is more than C commits.
+
+This decision cascades down the levels: when we merge a level we create a new
+set of commits that then compares to the next level.
+
+The first condition bounds the number of levels to be logarithmic in the total
+number of commits. The second condition bounds the total number of commits in
+a `graph-{hashN}` file and not in the `commit-graph` file, preventing
+significant performance issues when the stack merges and another process only
+partially reads the previous stack.
+
+The merge strategy values (2 for the size multiple, 64,000 for the maximum
+number of commits) could be extracted into config settings for full
+flexibility.
+
+## Deleting graph-{hash} files
+
+After a new tip file is written, some `graph-{hash}` files may no longer
+be part of a chain. It is important to remove these files from disk, eventually.
+The main reason to delay removal is that another process could read the
+`commit-graph-chain` file before it is rewritten, but then look for the
+`graph-{hash}` files after they are deleted.
+
+To allow holding old split commit-graphs for a while after they are unreferenced,
+we update the modified times of the files when they become unreferenced. Then,
+we scan the `$OBJDIR/info/commit-graphs/` directory for `graph-{hash}`
+files whose modified times are older than a given expiry window. This window
+defaults to zero, but can be changed using command-line arguments or a config
+setting.
+
+## Chains across multiple object directories
+
+In a repo with alternates, we look for the `commit-graph-chain` file starting
+in the local object directory and then in each alternate. The first file that
+exists defines our chain. As we look for the `graph-{hash}` files for
+each `{hash}` in the chain file, we follow the same pattern for the host
+directories.
+
+This allows commit-graphs to be split across multiple forks in a fork network.
+The typical case is a large "base" repo with many smaller forks.
+
+As the base repo advances, it will likely update and merge its commit-graph
+chain more frequently than the forks. If a fork updates their commit-graph after
+the base repo, then it should "reparent" the commit-graph chain onto the new
+chain in the base repo. When reading each `graph-{hash}` file, we track
+the object directory containing it. During a write of a new commit-graph file,
+we check for any changes in the source object directory and read the
+`commit-graph-chain` file for that source and create a new file based on those
+files. During this "reparent" operation, we necessarily need to collapse all
+levels in the fork, as all of the files are invalid against the new base file.
+
+It is crucial to be careful when cleaning up "unreferenced" `graph-{hash}.graph`
+files in this scenario. It falls to the user to define the proper settings for
+their custom environment:
+
+ 1. When merging levels in the base repo, the unreferenced files may still be
+ referenced by chains from fork repos.
+
+ 2. The expiry time should be set to a length of time such that every fork has
+ time to recompute their commit-graph chain to "reparent" onto the new base
+ file(s).
+
+ 3. If the commit-graph chain is updated in the base, the fork will not have
+ access to the new chain until its chain is updated to reference those files.
+ (This may change in the future [5].)

+High-level operations such as linkgit:git-commit[1] and
+linkgit:git-restore[1] work by moving data
between the working tree, the index, and the object database. Git
provides low-level operations which perform each of these steps
individually.
A good place to start is with the contents of the initial commit, with:
----------------------------------------------------
-$ git checkout e83c5163
+$ git switch --detach e83c5163
----------------------------------------------------
The initial revision lays the foundation for almost everything Git has
-----------------
-----------------------------------------------
-$ git branch # list all local branches in this repo
-$ git checkout test # switch working directory to branch "test"
-$ git branch new # create branch "new" starting at current HEAD
-$ git branch -d new # delete branch "new"
+$ git branch # list all local branches in this repo
+$ git switch test # switch working directory to branch "test"
+$ git branch new # create branch "new" starting at current HEAD
+$ git branch -d new # delete branch "new"

Instead of basing a new branch on current HEAD (the default), use:
Create and switch to a new branch at the same time:
-----------------------------------------------
-$ git checkout -b new v2.6.15
+$ git switch -c new v2.6.15
-----------------------------------------------
Update and examine branches from the repository you cloned from:

+/MSVC-DEFS-GEN
+/VCPKG-DEFS
+The Steps to Build Git with VS2015 or VS2017 from the command line.
+
+1. Install the "vcpkg" open source package manager and build essential
+ third-party libraries. The steps for this have been captured in a
+ set of convenience scripts. These can be run from a stock Command
+ Prompt or from an SDK bash window:
+
+ $ cd <repo_root>
+ $ ./compat/vcbuild/vcpkg_install.bat
+
+ The vcpkg tools and all of the third-party sources will be installed
+ in this folder:
+ <repo_root>/compat/vcbuild/vcpkg/
+
+ A file will be created with a set of Makefile macros pointing to a
+ unified "include", "lib", and "bin" directory (release and debug) for
+ all of the required packages. This file will be included by the main
+ Makefile:
+ <repo_root>/compat/vcbuild/MSVC-DEFS-GEN
+
+2. OPTIONALLY copy the third-party *.dll and *.pdb files into the repo
+ root to make it easier to run and debug git.exe without having to
+ manipulate your PATH. This is especially true for debug sessions in
+ Visual Studio.
+
+ Use ONE of the following forms which should match how you want to
+ compile git.exe.
+
+ $ ./compat/vcbuild/vcpkg_copy_packages.bat debug
+ $ ./compat/vcbuild/vcpkg_copy_packages.bat release
+
+3. Build git using MSVC from an SDK bash window using one of the
+ following commands:
+
+ $ make MSVC=1
+ $ make MSVC=1 DEBUG=1
+
+================================================================
+
+Alternatively, run `make vcxproj` and then load the generated `git.sln` in
+Visual Studio. The initial build will install the vcpkg system and build the
+dependencies automatically. This will take a while.
+
+Instead of generating the `git.sln` file yourself (which requires a full Git
+for Windows SDK), you may want to consider fetching the `vs/master` branch of
+https://github.com/git-for-windows/git instead (which is updated automatically
+via CI running `make vcxproj`). The `vs/master` branch does not require a Git
+for Windows to build, but you can run the test scripts in a regular Git Bash.
+
+Note that `make vcxproj` will automatically add and commit the generated `.sln`
+and `.vcxproj` files to the repo. This is necessary to allow building a
+fully-testable Git in Visual Studio, where a regular Git Bash can be used to
+run the test scripts (as opposed to a full Git for Windows SDK): a number of
+build targets, such as Git commands implemented as Unix shell scripts (where
+`@@SHELL_PATH@@` and other placeholders are interpolated) require a full-blown
+Git for Windows SDK (which is about 10x the size of a regular Git for Windows
+installation).
+
+If your plan is to open a Pull Request with Git for Windows, it is a good idea
+to drop this commit before submitting.
+
+================================================================
The Steps of Build Git with VS2008
1. You need the build environment, which contains the Git dependencies
--- /dev/null
+@ECHO OFF
+REM ================================================================
+REM You can use either GCC (the default) or MSVC to build git
+REM using the GIT-SDK command line tools.
+REM $ make
+REM $ make MSVC=1
+REM
+REM GIT-SDK BASH windows inherit environment variables with all of
+REM the bin/lib/include paths for GCC. It DOES NOT inherit values
+REM for the corresponding MSVC tools.
+REM
+REM During normal (non-git) Windows development, you launch one
+REM of the provided "developer command prompts" to set environment
+REM variables for the MSVC tools.
+REM
+REM Therefore, to allow MSVC command line builds of git from BASH
+REM and MAKE, we must blend these two different worlds. This script
+REM attempts to do that.
+REM ================================================================
+REM This BAT file starts in a plain (non-developer) command prompt,
+REM searches for the "best" commmand prompt setup script, installs
+REM it into the current CMD process, and exports the various MSVC
+REM environment variables for use by MAKE.
+REM
+REM The output of this script should be written to a make "include
+REM file" and referenced by the top-level Makefile.
+REM
+REM See "config.mak.uname" (look for compat/vcbuild/MSVC-DEFS-GEN).
+REM ================================================================
+REM The provided command prompts are custom to each VS release and
+REM filled with lots of internal knowledge (such as Registry settings);
+REM even their names vary by release, so it is not appropriate for us
+REM to look inside them. Rather, just run them in a subordinate
+REM process and extract the settings we need.
+REM ================================================================
+REM
+REM Current (VS2017 and beyond)
+REM -------------------
+REM Visual Studio 2017 introduced a new installation layout and
+REM support for side-by-side installation of multiple versions of
+REM VS2017. Furthermore, these can all coexist with installations
+REM of previous versions of VS (which have a completely different
+REM layout on disk).
+REM
+REM VS2017 Update 2 introduced a "vswhere.exe" command:
