-This code of conduct outlines our expectations for participants within
-the Git community, as well as steps for reporting unacceptable behavior.
-We are committed to providing a welcoming and inspiring community for
-all and expect our code of conduct to be honored. Anyone who violates
-this code of conduct may be banned from the community.
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to make participation in our project and
-our community a harassment-free experience for everyone, regardless of age,
-body size, disability, ethnicity, sex characteristics, gender identity and
-expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, religion, or sexual identity and
-orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or
-  advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic
-  address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions
-that are not aligned to this Code of Conduct, or to ban temporarily or
-permanently any contributor for other behaviors that they deem inappropriate,
-threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies within all project spaces, and it also applies
-when an individual is representing the project or its community in public
-spaces. Examples of representing a project or community include using an
-official project e-mail address, posting via an official social media account,
-or acting as an appointed representative at an online or offline event.
-Representation of a project may be further defined and clarified by project
-maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting the project team at git@sfconservancy.org. All
-complaints will be reviewed and investigated and will result in a response
-that is deemed necessary and appropriate to the circumstances. The project
-team is obligated to maintain confidentiality with regard to the reporter of
-an incident. Further details of specific enforcement policies may be posted
-separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good
-faith may face temporary or permanent repercussions as determined by other
-members of the project's leadership.

-= My First Object Walk
-
-== What's an Object Walk?
-
-The object walk is a key concept in Git - this is the process that underpins
-operations like object transfer and fsck. Beginning from a given commit, the
-list of objects is found by walking parent relationships between commits (commit
-X based on commit W) and containment relationships between objects (tree Y is
-contained within commit X, and blob Z is located within tree Y, giving our
-working tree for commit X something like `y/z.txt`).
-
-A related concept is the revision walk, which is focused on commit objects and
-their parent relationships and does not delve into other object types. The
-revision walk is used for operations like `git log`.
-
-=== Related Reading
-
-- `Documentation/user-manual.txt` under "Hacking Git" contains some coverage of
-  the revision walker in its various incarnations.
-- `revision.h`
-- https://eagain.net/articles/git-for-computer-scientists/[Git for Computer Scientists]
-  gives a good overview of the types of objects in Git and what your object
-  walk is really describing.
-
-== Setting Up
-
-Create a new branch from `master`.
-
-----
-git checkout -b revwalk origin/master
-----
-
-We'll put our fiddling into a new command. For fun, let's name it `git walken`.
-Open up a new file `builtin/walken.c` and set up the command handler:
-
-----
-/*
- * "git walken"
- *
- * Part of the "My First Object Walk" tutorial.
- */
-
-#include "builtin.h"
-
-int cmd_walken(int argc, const char **argv, const char *prefix)
-{
-	trace_printf(_("cmd_walken incoming...\n"));
-	return 0;
-}
-----
-
-NOTE: `trace_printf()` differs from `printf()` in that it can be turned on or
-off at runtime. For the purposes of this tutorial, we will write `walken` as
-though it is intended for use as a "plumbing" command: that is, a command which
-is used primarily in scripts, rather than interactively by humans (a "porcelain"
-command). So we will send our debug output to `trace_printf()` instead. When
-running, enable trace output by setting the environment variable `GIT_TRACE`.
-
-Add usage text and `-h` handling, like all subcommands should consistently do
-(our test suite will notice and complain if you fail to do so).
-
-----
-int cmd_walken(int argc, const char **argv, const char *prefix)
-{
-	const char * const walken_usage[] = {
-		N_("git walken"),
-		NULL,
-	}
-	struct option options[] = {
-		OPT_END()
-	};
-
-	argc = parse_options(argc, argv, prefix, options, walken_usage, 0);
-
-	...
-}
-----
-
-Also add the relevant line in `builtin.h` near `cmd_whatchanged()`:
-
-----
-int cmd_walken(int argc, const char **argv, const char *prefix);
-----
-
-Include the command in `git.c` in `commands[]` near the entry for `whatchanged`,
-maintaining alphabetical ordering:
-
-----
-{ "walken", cmd_walken, RUN_SETUP },
-----
-
-Add it to the `Makefile` near the line for `builtin/worktree.o`:
-
-----
-BUILTIN_OBJS += builtin/walken.o
-----
-
-Build and test out your command, without forgetting to ensure the `DEVELOPER`
-flag is set, and with `GIT_TRACE` enabled so the debug output can be seen:
-
-----
-$ echo DEVELOPER=1 >>config.mak
-$ make
-$ GIT_TRACE=1 ./bin-wrappers/git walken
-----
-
-NOTE: For a more exhaustive overview of the new command process, take a look at
-`Documentation/MyFirstContribution.txt`.
-
-NOTE: A reference implementation can be found at
-https://github.com/nasamuffin/git/tree/revwalk.
-
-=== `struct rev_cmdline_info`
-
-The definition of `struct rev_cmdline_info` can be found in `revision.h`.
-
-This struct is contained within the `rev_info` struct and is used to reflect
-parameters provided by the user over the CLI.
-
-`nr` represents the number of `rev_cmdline_entry` present in the array.
-
-`alloc` is used by the `ALLOC_GROW` macro. Check `cache.h` - this variable is
-used to track the allocated size of the list.
-
-Per entry, we find:
-
-`item` is the object provided upon which to base the object walk. Items in Git
-can be blobs, trees, commits, or tags. (See `Documentation/gittutorial-2.txt`.)
-
-`name` is the object ID (OID) of the object - a hex string you may be familiar
-with from using Git to organize your source in the past. Check the tutorial
-mentioned above towards the top for a discussion of where the OID can come
-from.
-
-`whence` indicates some information about what to do with the parents of the
-specified object. We'll explore this flag more later on; take a look at
-`Documentation/revisions.txt` to get an idea of what could set the `whence`
-value.
-
-`flags` are used to hint the beginning of the revision walk and are the first
-block under the `#include`s in `revision.h`. The most likely ones to be set in
-the `rev_cmdline_info` are `UNINTERESTING` and `BOTTOM`, but these same flags
-can be used during the walk, as well.
-
-=== `struct rev_info`
-
-This one is quite a bit longer, and many fields are only used during the walk
-by `revision.c` - not configuration options. Most of the configurable flags in
-`struct rev_info` have a mirror in `Documentation/rev-list-options.txt`. It's a
-good idea to take some time and read through that document.
-
-== Basic Commit Walk
-
-First, let's see if we can replicate the output of `git log --oneline`. We'll
-refer back to the implementation frequently to discover norms when performing
-an object walk of our own.
-
-To do so, we'll first find all the commits, in order, which preceded the current
-commit. We'll extract the name and subject of the commit from each.
-
-Ideally, we will also be able to find out which ones are currently at the tip of
-various branches.
-
-=== Setting Up
-
-Preparing for your object walk has some distinct stages.
-
-1. Perform default setup for this mode, and others which may be invoked.
-2. Check configuration files for relevant settings.
-3. Set up the `rev_info` struct.
-4. Tweak the initialized `rev_info` to suit the current walk.
-5. Prepare the `rev_info` for the walk.
-6. Iterate over the objects, processing each one.
-
-==== Default Setups
-
-Before examining configuration files which may modify command behavior, set up
-default state for switches or options your command may have. If your command
-utilizes other Git components, ask them to set up their default states as well.
-For instance, `git log` takes advantage of `grep` and `diff` functionality, so
-its `init_log_defaults()` sets its own state (`decoration_style`) and asks
-`grep` and `diff` to initialize themselves by calling each of their
-initialization functions.
-
-For our first example within `git walken`, we don't intend to use any other
-components within Git, and we don't have any configuration to do.  However, we
-may want to add some later, so for now, we can add an empty placeholder. Create
-a new function in `builtin/walken.c`:
-
-----
-static void init_walken_defaults(void)
-{
-	/*
-	 * We don't actually need the same components `git log` does; leave this
-	 * empty for now.
-	 */
-}
-----
-
-Make sure to add a line invoking it inside of `cmd_walken()`.
-
-----
-int cmd_walken(int argc, const char **argv, const char *prefix)
-{
-	init_walken_defaults();
-}
-----
-
-==== Configuring From `.gitconfig`
-
-Next, we should have a look at any relevant configuration settings (i.e.,
-settings readable and settable from `git config`). This is done by providing a
-callback to `git_config()`; within that callback, you can also invoke methods
-from other components you may need that need to intercept these options. Your
-callback will be invoked once per each configuration value which Git knows about
-(global, local, worktree, etc.).
-
-Similarly to the default values, we don't have anything to do here yet
-ourselves; however, we should call `git_default_config()` if we aren't calling
-any other existing config callbacks.
-
-Add a new function to `builtin/walken.c`:
-
-----
-static int git_walken_config(const char *var, const char *value, void *cb)
-{
-	/*
-	 * For now, we don't have any custom configuration, so fall back to
-	 * the default config.
-	 */
-	return git_default_config(var, value, cb);
-}
-----
-
-Make sure to invoke `git_config()` with it in your `cmd_walken()`:
-
-----
-int cmd_walken(int argc, const char **argv, const char *prefix)
-{
-	...
-
-	git_config(git_walken_config, NULL);
-
-	...
-}
-----
-
-==== Setting Up `rev_info`
-
-Now that we've gathered external configuration and options, it's time to
-initialize the `rev_info` object which we will use to perform the walk. This is
-typically done by calling `repo_init_revisions()` with the repository you intend
-to target, as well as the `prefix` argument of `cmd_walken` and your `rev_info`
-struct.
-
-Add the `struct rev_info` and the `repo_init_revisions()` call:
-----
-int cmd_walken(int argc, const char **argv, const char *prefix)
-{
-	/* This can go wherever you like in your declarations.*/
-	struct rev_info rev;
-	...
-
-	/* This should go after the git_config() call. */
-	repo_init_revisions(the_repository, &rev, prefix);
-
-	...
-}
-----
-
-==== Tweaking `rev_info` For the Walk
-
-We're getting close, but we're still not quite ready to go. Now that `rev` is
-initialized, we can modify it to fit our needs. This is usually done within a
-helper for clarity, so let's add one:
-
-----
-static void final_rev_info_setup(struct rev_info *rev)
-{
-	/*
-	 * We want to mimic the appearance of `git log --oneline`, so let's
-	 * force oneline format.
-	 */
-	get_commit_format("oneline", rev);
-
-	/* Start our object walk at HEAD. */
-	add_head_to_pending(rev);
-}
-----
-
-[NOTE]
-====
-Instead of using the shorthand `add_head_to_pending()`, you could do
-something like this:
-----
-	struct setup_revision_opt opt;
-
-	memset(&opt, 0, sizeof(opt));
-	opt.def = "HEAD";
-	opt.revarg_opt = REVARG_COMMITTISH;
-	setup_revisions(argc, argv, rev, &opt);
-----
-Using a `setup_revision_opt` gives you finer control over your walk's starting
-point.
-====
-
-Then let's invoke `final_rev_info_setup()` after the call to
-`repo_init_revisions()`:
-
-----
-int cmd_walken(int argc, const char **argv, const char *prefix)
-{
-	...
-
-	final_rev_info_setup(&rev);
-
-	...
-}
-----
-
-Later, we may wish to add more arguments to `final_rev_info_setup()`. But for
-now, this is all we need.
-
-==== Preparing `rev_info` For the Walk
-
-Now that `rev` is all initialized and configured, we've got one more setup step
-before we get rolling. We can do this in a helper, which will both prepare the
-`rev_info` for the walk, and perform the walk itself. Let's start the helper
-with the call to `prepare_revision_walk()`, which can return an error without
-dying on its own:
-
-----
-static void walken_commit_walk(struct rev_info *rev)
-{
-	if (prepare_revision_walk(rev))
-		die(_("revision walk setup failed"));
-}
-----
-
-NOTE: `die()` prints to `stderr` and exits the program. Since it will print to
-`stderr` it's likely to be seen by a human, so we will localize it.
-
-==== Performing the Walk!
-
-Finally! We are ready to begin the walk itself. Now we can see that `rev_info`
-can also be used as an iterator; we move to the next item in the walk by using
-`get_revision()` repeatedly. Add the listed variable declarations at the top and
-the walk loop below the `prepare_revision_walk()` call within your
-`walken_commit_walk()`:
-
-----
-static void walken_commit_walk(struct rev_info *rev)
-{
-	struct commit *commit;
-	struct strbuf prettybuf = STRBUF_INIT;
-
-	...
-
-	while ((commit = get_revision(rev))) {
-		strbuf_reset(&prettybuf);
-		pp_commit_easy(CMIT_FMT_ONELINE, commit, &prettybuf);
-		puts(prettybuf.buf);
-	}
-	strbuf_release(&prettybuf);
-}
-----
-
-NOTE: `puts()` prints a `char*` to `stdout`. Since this is the part of the
-command we expect to be machine-parsed, we're sending it directly to stdout.
-
-Give it a shot.
-
-----
-$ make
-$ ./bin-wrappers/git walken
-----
-
-You should see all of the subject lines of all the commits in
-your tree's history, in order, ending with the initial commit, "Initial revision
-of "git", the information manager from hell". Congratulations! You've written
-your first revision walk. You can play with printing some additional fields
-from each commit if you're curious; have a look at the functions available in
-`commit.h`.
-
-=== Adding a Filter
-
-Next, let's try to filter the commits we see based on their author. This is
-equivalent to running `git log --author=<pattern>`. We can add a filter by
-modifying `rev_info.grep_filter`, which is a `struct grep_opt`.
-
-First some setup. Add `init_grep_defaults()` to `init_walken_defaults()` and add
-`grep_config()` to `git_walken_config()`:
-
-----
-static void init_walken_defaults(void)
-{
-	init_grep_defaults(the_repository);
-}
-
-...
-
-static int git_walken_config(const char *var, const char *value, void *cb)
-{
-	grep_config(var, value, cb);
-	return git_default_config(var, value, cb);
-}
-----
-
-Next, we can modify the `grep_filter`. This is done with convenience functions
-found in `grep.h`. For fun, we're filtering to only commits from folks using a
-`gmail.com` email address - a not-very-precise guess at who may be working on
-Git as a hobby. Since we're checking the author, which is a specific line in the
-header, we'll use the `append_header_grep_pattern()` helper. We can use
-the `enum grep_header_field` to indicate which part of the commit header we want
-to search.
-
-In `final_rev_info_setup()`, add your filter line:
-
-----
-static void final_rev_info_setup(int argc, const char **argv,
-		const char *prefix, struct rev_info *rev)
-{
-	...
-
-	append_header_grep_pattern(&rev->grep_filter, GREP_HEADER_AUTHOR,
-		"gmail");
-	compile_grep_patterns(&rev->grep_filter);
-
-	...
-}
-----
-
-`append_header_grep_pattern()` adds your new "gmail" pattern to `rev_info`, but
-it won't work unless we compile it with `compile_grep_patterns()`.
-
-NOTE: If you are using `setup_revisions()` (for example, if you are passing a
-`setup_revision_opt` instead of using `add_head_to_pending()`), you don't need
-to call `compile_grep_patterns()` because `setup_revisions()` calls it for you.
-
-NOTE: We could add the same filter via the `append_grep_pattern()` helper if we
-wanted to, but `append_header_grep_pattern()` adds the `enum grep_context` and
-`enum grep_pat_token` for us.
-
-=== Changing the Order
-
-There are a few ways that we can change the order of the commits during a
-revision walk. Firstly, we can use the `enum rev_sort_order` to choose from some
-typical orderings.
-
-`topo_order` is the same as `git log --topo-order`: we avoid showing a parent
-before all of its children have been shown, and we avoid mixing commits which
-are in different lines of history. (`git help log`'s section on `--topo-order`
-has a very nice diagram to illustrate this.)
-
-Let's see what happens when we run with `REV_SORT_BY_COMMIT_DATE` as opposed to
-`REV_SORT_BY_AUTHOR_DATE`. Add the following:
-
-----
-static void final_rev_info_setup(int argc, const char **argv,
-		const char *prefix, struct rev_info *rev)
-{
-	...
-
-	rev->topo_order = 1;
-	rev->sort_order = REV_SORT_BY_COMMIT_DATE;
-
-	...
-}
-----
-
-Let's output this into a file so we can easily diff it with the walk sorted by
-author date.
-
-----
-$ make
-$ ./bin-wrappers/git walken > commit-date.txt
-----
-
-Then, let's sort by author date and run it again.
-
-----
-static void final_rev_info_setup(int argc, const char **argv,
-		const char *prefix, struct rev_info *rev)
-{
-	...
-
-	rev->topo_order = 1;
-	rev->sort_order = REV_SORT_BY_AUTHOR_DATE;
-
-	...
-}
-----
-
-----
-$ make
-$ ./bin-wrappers/git walken > author-date.txt
-----
-
-Finally, compare the two. This is a little less helpful without object names or
-dates, but hopefully we get the idea.
-
-----
-$ diff -u commit-date.txt author-date.txt
-----
-
-This display indicates that commits can be reordered after they're written, for
-example with `git rebase`.
-
-Let's try one more reordering of commits. `rev_info` exposes a `reverse` flag.
-Set that flag somewhere inside of `final_rev_info_setup()`:
-
-----
-static void final_rev_info_setup(int argc, const char **argv, const char *prefix,
-		struct rev_info *rev)
-{
-	...
-
-	rev->reverse = 1;
-
-	...
-}
-----
-
-Run your walk again and note the difference in order. (If you remove the grep
-pattern, you should see the last commit this call gives you as your current
-HEAD.)
-
-== Basic Object Walk
-
-So far we've been walking only commits. But Git has more types of objects than
-that! Let's see if we can walk _all_ objects, and find out some information
-about each one.
-
-We can base our work on an example. `git pack-objects` prepares all kinds of
-objects for packing into a bitmap or packfile. The work we are interested in
-resides in `builtins/pack-objects.c:get_object_list()`; examination of that
-function shows that the all-object walk is being performed by
-`traverse_commit_list()` or `traverse_commit_list_filtered()`. Those two
-functions reside in `list-objects.c`; examining the source shows that, despite
-the name, these functions traverse all kinds of objects. Let's have a look at
-the arguments to `traverse_commit_list_filtered()`, which are a superset of the
-arguments to the unfiltered version.
-
-- `struct list_objects_filter_options *filter_options`: This is a struct which
-  stores a filter-spec as outlined in `Documentation/rev-list-options.txt`.
-- `struct rev_info *revs`: This is the `rev_info` used for the walk.
-- `show_commit_fn show_commit`: A callback which will be used to handle each
-  individual commit object.
-- `show_object_fn show_object`: A callback which will be used to handle each
-  non-commit object (so each blob, tree, or tag).
-- `void *show_data`: A context buffer which is passed in turn to `show_commit`
-  and `show_object`.
-- `struct oidset *omitted`: A linked-list of object IDs which the provided
-  filter caused to be omitted.
-
-It looks like this `traverse_commit_list_filtered()` uses callbacks we provide
-instead of needing us to call it repeatedly ourselves. Cool! Let's add the
-callbacks first.
-
-For the sake of this tutorial, we'll simply keep track of how many of each kind
-of object we find. At file scope in `builtin/walken.c` add the following
-tracking variables:
-
-----
-static int commit_count;
-static int tag_count;
-static int blob_count;
-static int tree_count;
-----
-
-Commits are handled by a different callback than other objects; let's do that
-one first:
-
-----
-static void walken_show_commit(struct commit *cmt, void *buf)
-{
-	commit_count++;
-}
-----
-
-The `cmt` argument is fairly self-explanatory. But it's worth mentioning that
-the `buf` argument is actually the context buffer that we can provide to the
-traversal calls - `show_data`, which we mentioned a moment ago.
-
-Since we have the `struct commit` object, we can look at all the same parts that
-we looked at in our earlier commit-only walk. For the sake of this tutorial,
-though, we'll just increment the commit counter and move on.
-
-The callback for non-commits is a little different, as we'll need to check
-which kind of object we're dealing with:
-
-----
-static void walken_show_object(struct object *obj, const char *str, void *buf)
-{
-	switch (obj->type) {
-	case OBJ_TREE:
-		tree_count++;
-		break;
-	case OBJ_BLOB:
-		blob_count++;
-		break;
-	case OBJ_TAG:
-		tag_count++;
-		break;
-	case OBJ_COMMIT:
-		BUG("unexpected commit object in walken_show_object\n");
-	default:
-		BUG("unexpected object type %s in walken_show_object\n",
-			type_name(obj->type));
-	}
-}
-----
-
-Again, `obj` is fairly self-explanatory, and we can guess that `buf` is the same
-context pointer that `walken_show_commit()` receives: the `show_data` argument
-to `traverse_commit_list()` and `traverse_commit_list_filtered()`. Finally,
-`str` contains the name of the object, which ends up being something like
-`foo.txt` (blob), `bar/baz` (tree), or `v1.2.3` (tag).
-
-To help assure us that we aren't double-counting commits, we'll include some
-complaining if a commit object is routed through our non-commit callback; we'll
-also complain if we see an invalid object type. Since those two cases should be
-unreachable, and would only change in the event of a semantic change to the Git
-codebase, we complain by using `BUG()` - which is a signal to a developer that
-the change they made caused unintended consequences, and the rest of the
-codebase needs to be updated to understand that change. `BUG()` is not intended
-to be seen by the public, so it is not localized.
-
-Our main object walk implementation is substantially different from our commit
-walk implementation, so let's make a new function to perform the object walk. We
-can perform setup which is applicable to all objects here, too, to keep separate
-from setup which is applicable to commit-only walks.
-
-We'll start by enabling all types of objects in the `struct rev_info`.  We'll
-also turn on `tree_blobs_in_commit_order`, which means that we will walk a
-commit's tree and everything it points to immediately after we find each commit,
-as opposed to waiting for the end and walking through all trees after the commit
-history has been discovered. With the appropriate settings configured, we are
-ready to call `prepare_revision_walk()`.
-
-----
-static void walken_object_walk(struct rev_info *rev)
-{
-	rev->tree_objects = 1;
-	rev->blob_objects = 1;
-	rev->tag_objects = 1;
-	rev->tree_blobs_in_commit_order = 1;
-
-	if (prepare_revision_walk(rev))
-		die(_("revision walk setup failed"));
-
-	commit_count = 0;
-	tag_count = 0;
-	blob_count = 0;
-	tree_count = 0;
-----
-
-Let's start by calling just the unfiltered walk and reporting our counts.
-Complete your implementation of `walken_object_walk()`:
-
-----
-	traverse_commit_list(rev, walken_show_commit, walken_show_object, NULL);
-
-	printf("commits %d\nblobs %d\ntags %d\ntrees %d\n", commit_count,
-		blob_count, tag_count, tree_count);
-}
-----
-
-NOTE: This output is intended to be machine-parsed. Therefore, we are not
-sending it to `trace_printf()`, and we are not localizing it - we need scripts
-to be able to count on the formatting to be exactly the way it is shown here.
-If we were intending this output to be read by humans, we would need to localize
-it with `_()`.
-
-Finally, we'll ask `cmd_walken()` to use the object walk instead. Discussing
-command line options is out of scope for this tutorial, so we'll just hardcode
-a branch we can change at compile time. Where you call `final_rev_info_setup()`
-and `walken_commit_walk()`, instead branch like so:
-
-----
-	if (1) {
-		add_head_to_pending(&rev);
-		walken_object_walk(&rev);
-	} else {
-		final_rev_info_setup(argc, argv, prefix, &rev);
-		walken_commit_walk(&rev);
-	}
-----
-
-NOTE: For simplicity, we've avoided all the filters and sorts we applied in
-`final_rev_info_setup()` and simply added `HEAD` to our pending queue. If you
-want, you can certainly use the filters we added before by moving
-`final_rev_info_setup()` out of the conditional and removing the call to
-`add_head_to_pending()`.
-
-Now we can try to run our command! It should take noticeably longer than the
-commit walk, but an examination of the output will give you an idea why. Your
-output should look similar to this example, but with different counts:
-
-----
-Object walk completed. Found 55733 commits, 100274 blobs, 0 tags, and 104210 trees.
-----
-
-This makes sense. We have more trees than commits because the Git project has
-lots of subdirectories which can change, plus at least one tree per commit. We
-have no tags because we started on a commit (`HEAD`) and while tags can point to
-commits, commits can't point to tags.
-
-NOTE: You will have different counts when you run this yourself! The number of
-objects grows along with the Git project.
-
-=== Adding a Filter
-
-There are a handful of filters that we can apply to the object walk laid out in
-`Documentation/rev-list-options.txt`. These filters are typically useful for
-operations such as creating packfiles or performing a partial clone. They are
-defined in `list-objects-filter-options.h`. For the purposes of this tutorial we
-will use the "tree:1" filter, which causes the walk to omit all trees and blobs
-which are not directly referenced by commits reachable from the commit in
-`pending` when the walk begins. (`pending` is the list of objects which need to
-be traversed during a walk; you can imagine a breadth-first tree traversal to
-help understand. In our case, that means we omit trees and blobs not directly
-referenced by `HEAD` or `HEAD`'s history, because we begin the walk with only
-`HEAD` in the `pending` list.)
-
-First, we'll need to `#include "list-objects-filter-options.h`" and set up the
-`struct list_objects_filter_options` at the top of the function.
-
-----
-static void walken_object_walk(struct rev_info *rev)
-{
-	struct list_objects_filter_options filter_options = {};
-
-	...
-----
-
-For now, we are not going to track the omitted objects, so we'll replace those
-parameters with `NULL`. For the sake of simplicity, we'll add a simple
-build-time branch to use our filter or not. Replace the line calling
-`traverse_commit_list()` with the following, which will remind us which kind of
-walk we've just performed:
-
-----
-	if (0) {
-		/* Unfiltered: */
-		trace_printf(_("Unfiltered object walk.\n"));
-		traverse_commit_list(rev, walken_show_commit,
-				walken_show_object, NULL);
-	} else {
-		trace_printf(
-			_("Filtered object walk with filterspec 'tree:1'.\n"));
-		parse_list_objects_filter(&filter_options, "tree:1");
-
-		traverse_commit_list_filtered(&filter_options, rev,
-			walken_show_commit, walken_show_object, NULL, NULL);
-	}
-----
-
-`struct list_objects_filter_options` is usually built directly from a command
-line argument, so the module provides an easy way to build one from a string.
-Even though we aren't taking user input right now, we can still build one with
-a hardcoded string using `parse_list_objects_filter()`.
-
-With the filter spec "tree:1", we are expecting to see _only_ the root tree for
-each commit; therefore, the tree object count should be less than or equal to
-the number of commits. (For an example of why that's true: `git commit --revert`
-points to the same tree object as its grandparent.)
-
-=== Counting Omitted Objects
-
-We also have the capability to enumerate all objects which were omitted by a
-filter, like with `git log --filter=<spec> --filter-print-omitted`. Asking
-`traverse_commit_list_filtered()` to populate the `omitted` list means that our
-object walk does not perform any better than an unfiltered object walk; all
-reachable objects are walked in order to populate the list.
-
-First, add the `struct oidset` and related items we will use to iterate it:
-
-----
-static void walken_object_walk(
-	...
-
-	struct oidset omitted;
-	struct oidset_iter oit;
-	struct object_id *oid = NULL;
-	int omitted_count = 0;
-	oidset_init(&omitted, 0);
-
-	...
-----
-
-Modify the call to `traverse_commit_list_filtered()` to include your `omitted`
-object:
-
-----
-	...
-
-		traverse_commit_list_filtered(&filter_options, rev,
-			walken_show_commit, walken_show_object, NULL, &omitted);
-
-	...
-----
-
-Then, after your traversal, the `oidset` traversal is pretty straightforward.
-Count all the objects within and modify the print statement:
-
-----
-	/* Count the omitted objects. */
-	oidset_iter_init(&omitted, &oit);
-
-	while ((oid = oidset_iter_next(&oit)))
-		omitted_count++;
-
-	printf("commits %d\nblobs %d\ntags %d\ntrees%d\nomitted %d\n",
-		commit_count, blob_count, tag_count, tree_count, omitted_count);
-----
-
-By running your walk with and without the filter, you should find that the total
-object count in each case is identical. You can also time each invocation of
-the `walken` subcommand, with and without `omitted` being passed in, to confirm
-to yourself the runtime impact of tracking all omitted objects.
-
-=== Changing the Order
-
-Finally, let's demonstrate that you can also reorder walks of all objects, not
-just walks of commits. First, we'll make our handlers chattier - modify
-`walken_show_commit()` and `walken_show_object()` to print the object as they
-go:
-
-----
-static void walken_show_commit(struct commit *cmt, void *buf)
-{
-	trace_printf("commit: %s\n", oid_to_hex(&cmt->object.oid));
-	commit_count++;
-}
-
-static void walken_show_object(struct object *obj, const char *str, void *buf)
-{
-	trace_printf("%s: %s\n", type_name(obj->type), oid_to_hex(&obj->oid));
-
-	...
-}
-----
-
-NOTE: Since we will be examining this output directly as humans, we'll use
-`trace_printf()` here. Additionally, since this change introduces a significant
-number of printed lines, using `trace_printf()` will allow us to easily silence
-those lines without having to recompile.
-
-(Leave the counter increment logic in place.)
-
-With only that change, run again (but save yourself some scrollback):
-
-----
-$ GIT_TRACE=1 ./bin-wrappers/git walken | head -n 10
-----
-
-Take a look at the top commit with `git show` and the object ID you printed; it
-should be the same as the output of `git show HEAD`.
-
-Next, let's change a setting on our `struct rev_info` within
-`walken_object_walk()`. Find where you're changing the other settings on `rev`,
-such as `rev->tree_objects` and `rev->tree_blobs_in_commit_order`, and add the
-`reverse` setting at the bottom:
-
-----
-	...
-
-	rev->tree_objects = 1;
-	rev->blob_objects = 1;
-	rev->tag_objects = 1;
-	rev->tree_blobs_in_commit_order = 1;
-	rev->reverse = 1;
-
-	...
-----
-
-Now, run again, but this time, let's grab the last handful of objects instead
-of the first handful:
-
-----
-$ make
-$ GIT_TRACE=1 ./bin-wrappers git walken | tail -n 10
-----
-
-The last commit object given should have the same OID as the one we saw at the
-top before, and running `git show <oid>` with that OID should give you again
-the same results as `git show HEAD`. Furthermore, if you run and examine the
-first ten lines again (with `head` instead of `tail` like we did before applying
-the `reverse` setting), you should see that now the first commit printed is the
-initial commit, `e83c5163`.
-
-== Wrapping Up
-
-Let's review. In this tutorial, we:
-
-- Built a commit walk from the ground up
-- Enabled a grep filter for that commit walk
-- Changed the sort order of that filtered commit walk
-- Built an object walk (tags, commits, trees, and blobs) from the ground up
-- Learned how to add a filter-spec to an object walk
-- Changed the display order of the filtered object walk

-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.
-
- * "git bundle verify" needs to see if prerequisite objects exist in
-   the receiving repository, but the command did not check if we are
-   in a repository upfront, which has been corrected.
-
- * "git merge --squash" is designed to update the working tree and the
-   index without creating the commit, and this cannot be countermanded
-   by adding the "--commit" option; the command now refuses to work
-   when both options are given.
-
- * The data collected by fsmonitor was not properly written back to
-   the on-disk index file, breaking t7519 tests occasionally, which
-   has been corrected.
-
- * Update to Unicode 12.1 width table.
-
- * The command line to invoke a "git cat-file" command from inside
-   "git p4" was not properly quoted to protect a caret and running a
-   broken command on Windows, which has been corrected.
-
- * "git request-pull" learned to warn when the ref we ask them to pull
-   from in the local repository and in the published repository are
-   different.
-
- * When creating a partial clone, the object filtering criteria is
-   recorded for the origin of the clone, but this incorrectly used a
-   hardcoded name "origin" to name that remote; it has been corrected
-   to honor the "--origin <name>" option.
-
- * "git fetch" into a lazy clone forgot to fetch base objects that are
-   necessary to complete delta in a thin packfile, which has been
-   corrected.
-
- * The filter_data used in the list-objects-filter (which manages a
-   lazily sparse clone repository) did not use the dynamic array API
-   correctly---'nr' is supposed to point at one past the last element
-   of the array in use.  This has been corrected.
-
- * The description about slashes in gitignore patterns (used to
-   indicate things like "anchored to this level only" and "only
-   matches directories") has been revamped.
-
- * The URL decoding code has been updated to avoid going past the end
-   of the string while parsing %-<hex>-<hex> sequence.
-
- * The list of for-each like macros used by clang-format has been
-   updated.
-
- * "git branch --list" learned to show branches that are checked out
-   in other worktrees connected to the same repository prefixed with
-   '+', similar to the way the currently checked out branch is shown
-   with '*' in front.
-   (merge 6e9381469e nb/branch-show-other-worktrees-head later to maint).
-
- * Code restructuring during 2.20 period broke fetching tags via
-   "import" based transports.
-
- * The commit-graph file is now part of the "files that the runtime
-   may keep open file descriptors on, all of which would need to be
-   closed when done with the object store", and the file descriptor to
-   an existing commit-graph file now is closed before "gc" finalizes a
-   new instance to replace it.
-
- * "git checkout -p" needs to selectively apply a patch in reverse,
-   which did not work well.
-
- * Code clean-up to avoid signed integer wraparounds during binary search.
-
- * "git interpret-trailers" always treated '#' as the comment
-   character, regardless of core.commentChar setting, which has been
-   corrected.
-
- * "git stash show 23" used to work, but no more after getting
-   rewritten in C; this regression has been corrected.
-
- * "git rebase --abort" used to leave refs/rewritten/ when concluding
-   "git rebase -r", which has been corrected.
-
- * An incorrect list of options was cached after command line
-   completion failed (e.g. trying to complete a command that requires
-   a repository outside one), which has been corrected.
-
- * The code to parse scaled numbers out of configuration files has
-   been made more robust and also easier to follow.
-
- * The codepath to compute delta islands used to spew progress output
-   without giving the callers any way to squelch it, which has been
-   fixed.
-
- * Protocol capabilities that go over wire should never be translated,
-   but it was incorrectly marked for translation, which has been
-   corrected.  The output of protocol capabilities for debugging has
-   been tweaked a bit.
-
- * Use "Erase in Line" CSI sequence that is already used in the editor
-   support to clear cruft in the progress output.
-
- * "git submodule foreach" did not protect command line options passed
-   to the command to be run in each submodule correctly, when the
-   "--recursive" option was in use.
-
- * The configuration variable rebase.rescheduleFailedExec should be
-   effective only while running an interactive rebase and should not
-   affect anything when running a non-interactive one, which was not
-   the case.  This has been corrected.
-
- * The "git clone" documentation refers to command line options in its
-   description in the short form; they have been replaced with long
-   forms to make them more recognisable.
-
- * Generation of pack bitmaps are now disabled when .keep files exist,
-   as these are mutually exclusive features.
-   (merge 7328482253 ew/repack-with-bitmaps-by-default later to maint).
-
- * "git rm" to resolve a conflicted path leaked an internal message
-   "needs merge" before actually removing the path, which was
-   confusing.  This has been corrected.
-
- * "git stash --keep-index" did not work correctly on paths that have
-   been removed, which has been fixed.
-   (merge b932f6a5e8 tg/stash-keep-index-with-removed-paths later to maint).
-
- * Window 7 update ;-)
-
- * A codepath that reads from GPG for signed object verification read
-   past the end of allocated buffer, which has been fixed.
-
- * "git clean" silently skipped a path when it cannot lstat() it; now
-   it gives a warning.
-
- * "git push --atomic" that goes over the transport-helper (namely,
-   the smart http transport) failed to prevent refs to be pushed when
-   it can locally tell that one of the ref update will fail without
-   having to consult the other end, which has been corrected.
-
- * The internal diff machinery can be made to read out of bounds while
-   looking for --function-context line in a corner case, which has been
-   corrected.
-   (merge b777f3fd61 jk/xdiff-clamp-funcname-context-index later to maint).
-
- * Other code cleanup, docfix, build fix, etc.
-   (merge fbec05c210 cc/test-oidmap later to maint).

-Git 2.24 Release Notes
-======================
-
-Updates since v2.23
--------------------
-
-Backward compatibility note
-
- * "filter-branch" is showing its age and alternatives are available.
-   From this release, we started to discourage its use and hint
-   people about filter-repo.
-
-UI, Workflows & Features
-
- * We now have an active interim maintainer for the Git-Gui part of
-   the system.  Praise and thank Pratyush Yadav for volunteering.
-
- * The command line parser learned "--end-of-options" notation; the
-   standard convention for scripters to have hardcoded set of options
-   first on the command line, and force the command to treat end-user
-   input as non-options, has been to use "--" as the delimiter, but
-   that would not work for commands that use "--" as a delimiter
-   between revs and pathspec.
-
- * A mechanism to affect the default setting for a (related) group of
-   configuration variables is introduced.
-
- * "git fetch" learned "--set-upstream" option to help those who first
-   clone from their private fork they intend to push to, add the true
-   upstream via "git remote add" and then "git fetch" from it.
-
- * Device-tree files learned their own userdiff patterns.
-   (merge 3c81760bc6 sb/userdiff-dts later to maint).
-
- * "git rebase --rebase-merges" learned to drive different merge
-   strategies and pass strategy specific options to them.
-
- * A new "pre-merge-commit" hook has been introduced.
-
- * Command line completion updates for "git -c var.name=val" have been
-   added.
-
- * The lazy clone machinery has been taught that there can be more
-   than one promisor remote and consult them in order when downloading
-   missing objects on demand.
-
- * The list-objects-filter API (used to create a sparse/lazy clone)
-   learned to take a combined filter specification.
-
- * The documentation and tests for "git format-patch" have been
-   cleaned up.
-
- * On Windows, the root level of UNC share is now allowed to be used
-   just like any other directory.
-
- * The command line completion support (in contrib/) learned about the
-   "--skip" option of "git revert" and "git cherry-pick".
-
- * "git rebase --keep-base <upstream>" tries to find the original base
-   of the topic being rebased and rebase on top of that same base,
-   which is useful when running the "git rebase -i" (and its limited
-   variant "git rebase -x").
-
-   The command also has learned to fast-forward in more cases where it
-   can instead of replaying to recreate identical commits.
-
- * A configuration variable tells "git fetch" to write the commit
-   graph after finishing.
-
- * "git add -i" has been taught to show the total number of hunks and
-   the hunks that has been processed so far when showing prompts.
-
- * "git fetch --jobs=<n>" allowed <n> parallel jobs when fetching
-   submodules, but this did not apply to "git fetch --multiple" that
-   fetches from multiple remote repositories.  It now does.
-
- * The installation instruction for zsh completion script (in
-   contrib/) has been a bit improved.
-
-
-Performance, Internal Implementation, Development Support etc.
-
- * The code to write commit-graph over given commit object names has
-   been made a bit more robust.
-
- * The first line of verbose output from each test piece now carries
-   the test name and number to help scanning with eyeballs.
-
- * Further clean-up of the initialization code.
-
- * xmalloc() used to have a mechanism to ditch memory and address
-   space resources as the last resort upon seeing an allocation
-   failure from the underlying malloc(), which made the code complex
-   and thread-unsafe with dubious benefit, as major memory resource
-   users already do limit their uses with various other mechanisms.
-   It has been simplified away.
-
- * Unnecessary full-tree diff in "git log -L" machinery has been
-   optimized away.
-
- * The http transport lacked some optimization the native transports
-   learned to avoid unnecessary ref advertisement, which has been
-   corrected.
-
- * Preparation for SHA-256 upgrade continues in the test department.
-   (merge 0c37c41d13 bc/hash-independent-tests-part-5 later to maint).
-
- * The memory ownership model of the "git fast-import" got
-   straightened out.
-
- * Output from trace2 subsystem is formatted more prettily now.
-
- * The internal code originally invented for ".gitignore" processing
-   got reshuffled and renamed to make it less tied to "excluding" and
-   stress more that it is about "matching", as it has been reused for
-   things like sparse checkout specification that want to check if a
-   path is "included".
-
- * "git stash" learned to write refreshed index back to disk.
-
- * Coccinelle checks are done on more source files than before now.
-
- * The cache-tree code has been taught to be less aggressive in
-   attempting to see if a tree object it computed already exists in
-   the repository.
-
- * The code to parse and use the commit-graph file has been made more
-   robust against corrupted input.
-
- * The hg-to-git script (in contrib/) has been updated to work with
-   Python 3.
-
- * Update the way build artifacts in t/helper/ directory are ignored.
-
- * Preparation for SHA-256 upgrade continues.
-
- * "git log --graph" for an octopus merge is sometimes colored
-   incorrectly, which is demonstrated and documented but not yet
-   fixed.
-
- * The trace2 output, when sending them to files in a designated
-   directory, can populate the directory with too many files; a
-   mechanism is introduced to set the maximum number of files and
-   discard further logs when the maximum is reached.
-
- * We have adopted a Code-of-conduct document.
-   (merge 3f9ef874a7 jk/coc later to maint).
-
-
-Fixes since v2.23
------------------
-
- * "git grep --recurse-submodules" that looks at the working tree
-   files looked at the contents in the index in submodules, instead of
-   files in the working tree.
-   (merge 6a289d45c0 mt/grep-submodules-working-tree later to maint).
-
- * Codepaths to walk tree objects have been audited for integer
-   overflows and hardened.
-   (merge 5aa02f9868 jk/tree-walk-overflow later to maint).
-
- * "git pack-refs" can lose refs that are created while running, which
-   is getting corrected.
-   (merge a613d4f817 sc/pack-refs-deletion-racefix later to maint).
-
- * "git checkout" and "git restore" to re-populate the index from a
-   tree-ish (typically HEAD) did not work correctly for a path that
-   was removed and then added again with the intent-to-add bit, when
-   the corresponding working tree file was empty.  This has been
-   corrected.
-
- * Compilation fix.
-   (merge 70597e8386 rs/nedalloc-fixlets later to maint).
-
- * "git gui" learned to call the clean-up procedure before exiting.
-   (merge 0d88f3d2c5 py/git-gui-do-quit later to maint).
-
- * We promoted the "indent heuristics" that decides where to split
-   diff hunks from experimental to the default a few years ago, but
-   some stale documentation still marked it as experimental, which has
-   been corrected.
-   (merge 64e5e1fba1 sg/diff-indent-heuristic-non-experimental later to maint).
-
- * Fix a mismerge that happened in 2.22 timeframe.
-   (merge acb7da05ac en/checkout-mismerge-fix later to maint).
-
- * "git archive" recorded incorrect length in extended pax header in
-   some corner cases, which has been corrected.
-   (merge 71d41ff651 rs/pax-extended-header-length-fix later to maint).
-
- * On-demand object fetching in lazy clone incorrectly tried to fetch
-   commits from submodule projects, while still working in the
-   superproject, which has been corrected.
-   (merge a63694f523 jt/diff-lazy-fetch-submodule-fix later to maint).
-
- * Prepare get_short_oid() codepath to be thread-safe.
-   (merge 7cfcb16b0e rs/sort-oid-array-thread-safe later to maint).
-
- * "for-each-ref" and friends that show refs did not protect themselves
-   against ancient tags that did not record tagger names when asked to
-   show "%(taggername)", which have been corrected.
-   (merge 8b3f33ef11 mp/for-each-ref-missing-name-or-email later to maint).
-
- * The "git am" based backend of "git rebase" ignored the result of
-   updating ".gitattributes" done in one step when replaying
-   subsequent steps.
-   (merge 2c65d90f75 bc/reread-attributes-during-rebase later to maint).
-
- * Tell cURL library to use the same malloc() implementation, with the
-   xmalloc() wrapper, as the rest of the system, for consistency.
-   (merge 93b980e58f cb/curl-use-xmalloc later to maint).
-
- * Build fix to adjust .gitignore to unignore a path that we started to track.
-   (merge aac6ff7b5b js/visual-studio later to maint).
-
- * A few implementation fixes in the notes API.
-   (merge 60fe477a0b mh/notes-duplicate-entries later to maint).
-
- * Fix an earlier regression to "git push --all" which should have
-   been forbidden when the target remote repository is set to be a
-   mirror.
-   (merge 8e4c8af058 tg/push-all-in-mirror-forbidden later to maint).
-
- * Fix an earlier regression in the test suite, which mistakenly
-   stopped running HTTPD tests.
-   (merge 3960290675 sg/git-test-boolean later to maint).
-
- * "git rebase --autostash <upstream> <branch>", when <branch> is
-   different from the current branch, incorrectly moved the tip of the
-   current branch, which has been corrected.
-   (merge bf1e28e0ad bw/rebase-autostash-keep-current-branch later to maint).
-
- * Update support for Asciidoctor documentation toolchain.
-   (merge 83b0b8953e ma/asciidoctor-refmiscinfo later to maint).
-
- * Start using DocBook 5 (instead of DocBook 4.5) as Asciidoctor 2.0
-   no longer works with the older one.
-   (merge f6461b82b9 bc/doc-use-docbook-5 later to maint).
-
- * The markup used in user-manual has been updated to work better with
-   asciidoctor.
-   (merge c4d2f6143a ma/user-manual-markup-update later to maint).
-
- * Make sure the grep machinery does not abort when seeing a payload
-   that is not UTF-8 even when JIT is not in use with PCRE1.
-   (merge ad7c543e3b cb/skip-utf8-check-with-pcre1 later to maint).
-
- * The name of the blob object that stores the filter specification
-   for sparse cloning/fetching was interpreted in a wrong place in the
-   code, causing Git to abort.
-
- * "git log --decorate-refs-exclude=<pattern>" was incorrectly
-   overruled when the "--simplify-by-decoration" option is used, which
-   has been corrected.
-   (merge 0cc7380d88 rs/simplify-by-deco-with-deco-refs-exclude later to maint).
-
- * The "upload-pack" (the counterpart of "git fetch") needs to disable
-   commit-graph when responding to a shallow clone/fetch request, but
-   the way this was done made Git panic, which has been corrected.
-
- * The object traversal machinery has been optimized not to load tree
-   objects when we are only interested in commit history.
-   (merge 72ed80c784 jk/list-objects-optim-wo-trees later to maint).
-
- * The object name parser for "Nth parent" syntax has been made more
-   robust against integer overflows.
-   (merge 59fa5f5a25 rs/nth-parent-parse later to maint).
-
- * The code used in following tags in "git fetch" has been optimized.
-   (merge b7e2d8bca5 ms/fetch-follow-tag-optim later to maint).
-
- * Regression fix for progress output.
-   (merge 2bb74b53a4 sg/progress-fix later to maint).
-
- * A bug in merge-recursive code that triggers when a branch with a
-   symbolic link is merged with a branch that replaces it with a
-   directory has been fixed.
-   (merge 83e3ad3b12 jt/merge-recursive-symlink-is-not-a-dir-in-way later to maint).
-
- * The rename detection logic sorts a list of rename source candidates
-   by similarity to pick the best candidate, which means that a tie
-   between sources with the same similarity is broken by the original
-   location in the original candidate list (which is sorted by path).
-   Force the sorting by similarity done with a stable sort, which is
-   not promised by system supplied qsort(3), to ensure consistent
-   results across platforms.
-   (merge 2049b8dc65 js/diff-rename-force-stable-sort later to maint).
-
- * The code to skip "UTF" and "UTF-" prefix, when computing an advice
-   message, did not work correctly when the prefix was "UTF", which
-   has been fixed.
-   (merge b181676ce9 rs/convert-fix-utf-without-dash later to maint).
-
- * The author names taken from SVN repositories may have extra leading
-   or trailing whitespaces, which are now munged away.
-   (merge 4ddd4bddb1 tk/git-svn-trim-author-name later to maint).
-
- * "git rebase -i" showed a wrong HEAD while "reword" open the editor.
-   (merge b0a3186140 pw/rebase-i-show-HEAD-to-reword later to maint).
-
- * A few simplification and bugfixes to PCRE interface.
-   (merge c581e4a749 ab/pcre-jit-fixes later to maint).
-
- * PCRE fixes.
-   (merge ff61681b46 cb/pcre1-cleanup later to maint).
-
- * "git range-diff" segfaulted when diff.noprefix configuration was
-   used, as it blindly expected the patch it internally generates to
-   have the standard a/ and b/ prefixes.  The command now forces the
-   internal patch to be built without any prefix, not to be affected
-   by any end-user configuration.
-   (merge 937b76ed49 js/range-diff-noprefix later to maint).
-
- * "git stash apply" in a subdirectory of a secondary worktree failed
-   to access the worktree correctly, which has been corrected.
-   (merge dfd557c978 js/stash-apply-in-secondary-worktree later to maint).
-
- * The merge-recursive machinery is one of the most complex parts of
-   the system that accumulated cruft over time.  This large series
-   cleans up the implementation quite a bit.
-   (merge b657047719 en/merge-recursive-cleanup later to maint).
-
- * Pretty-printed command line formatter (used in e.g. reporting the
-   command being run by the tracing API) had a bug that lost an
-   argument that is an empty string, which has been corrected.
-   (merge ce2d7ed2fd gs/sq-quote-buf-pretty later to maint).
-
- * "git range-diff" failed to handle mode-only change, which has been
-   corrected.
-   (merge 2b6a9b13ca tg/range-diff-output-update later to maint).
-
- * Dev support update.
-   (merge 4f3c1dc5d6 dl/allow-running-cocci-verbosely later to maint).
-
- * "git format-patch -o <outdir>" did an equivalent of "mkdir <outdir>"
-   not "mkdir -p <outdir>", which was corrected.
-
- * "git stash save" lost local changes to submodules, which has been
-   corrected.
-   (merge 556895d0c8 jj/stash-reset-only-toplevel later to maint).
-
- * The atomic push over smart HTTP transport did not work, which has
-   been corrected.
-   (merge 6f1194246a bc/smart-http-atomic-push later to maint).
-
- * Other code cleanup, docfix, build fix, etc.
-   (merge d1387d3895 en/fast-import-merge-doc later to maint).

-Git 2.25 Release Notes
-======================
-
-Updates since v2.24
--------------------
-
-Backward compatibility notes
-
-
-UI, Workflows & Features
-
- * A tutorial on object enumeration has been added.
-
- * The branch description ("git branch --edit-description") has been
-   used to fill the body of the cover letters by the format-patch
-   command; this has been enhanced so that the subject can also be
-   filled.
-
- * "git rebase --preserve-merges" has been marked as deprecated; this
-   release stops advertising it in the "git rebase -h" output.
-
- * The code to generate multi-pack index learned to show (or not to
-   show) progress indicators.
-
- * "git apply --3way" learned to honor merge.conflictStyle
-   configuration variable, like merges would.
-
- * The custom format for "git log --format=<format>" learned the l/L
-   placeholder that is similar to e/E that fills in the e-mail
-   address, but only the local part on the left side of '@'.
-
- * Documentation pages for "git shortlog" now list commit limiting
-   options explicitly.
-
- * The patterns to detect function boundary for Elixir language has
-   been added.
-
- * The completion script (in contrib/) learned that the "--onto"
-   option of "git rebase" can take its argument as the value of the
-   option.
-
- * The userdiff machinery has been taught that "async def" is another
-   way to begin a "function" in Python.
-
- * "git range-diff" learned to take the "--notes=<ref>" and the
-   "--no-notes" options to control the commit notes included in the
-   log message that gets compared.
-
- * "git rev-parse --show-toplevel" run outside of any working tree did
-   not error out, which has been corrected.
-
- * A few commands learned to take the pathspec from the standard input
-   or a named file, instead of taking it as the command line
-   arguments, with the "--pathspec-from-file" option.
-
- * "git submodule" learned a subcommand "set-url".
-
- * "git log" family learned "--pretty=reference" that gives the name
-   of a commit in the format that is often used to refer to it in log
-   messages.
-
- * The interaction between "git clone --recurse-submodules" and
-   alternate object store was ill-designed.  The documentation and
-   code have been taught to make more clear recommendations when the
-   users see failures.
-
- * Management of sparsely checked-out working tree has gained a
-   dedicated "sparse-checkout" command.
-
- * Miscellaneous small UX improvements on "git-p4".
-
- * "git sparse-checkout list" subcommand learned to give its output in
-   a more concise form when the "cone" mode is in effect.
-
-
-Performance, Internal Implementation, Development Support etc.
-
- * Debugging support for lazy cloning has been a bit improved.
-
- * Move the definition of a set of bitmask constants from 0ctal
-   literal to (1U<<count) notation.
-
- * Test updates to prepare for SHA-2 transition continues.
-
- * Crufty code and logic accumulated over time around the object
-   parsing and low-level object access used in "git fsck" have been
-   cleaned up.
-
- * The implementation of "git log --graph" got refactored and then its
-   output got simplified.
-
- * Follow recent push to move API docs from Documentation/ to header
-   files and update config.h
-
- * "git bundle" has been taught to use the parse options API.  "git
-   bundle verify" learned "--quiet" and "git bundle create" learned
-   options to control the progress output.
-
- * Handling of commit objects that use non UTF-8 encoding during
-   "rebase -i" has been improved.
-
- * The beginning of rewriting "git add -i" in C.
-
- * A label used in the todo list that are generated by "git rebase
-   --rebase-merges" is used as a part of a refname; the logic to come
-   up with the label has been tightened to avoid names that cannot be
-   used as such.
-
- * The logic to avoid duplicate label names generated by "git rebase
-   --rebase-merges" forgot that the machinery itself uses "onto" as a
-   label name, which must be avoided by auto-generated labels, which
-   has been corrected.
-
- * We have had compatibility fallback macro definitions for "PRIuMAX",
-   "PRIu32", etc. but did not for "PRIdMAX", while the code used the
-   last one apparently without any hiccup reported recently.  The
-   fallback macro definitions for these <inttypes.h> macros that must
-   appear in C99 systems have been removed.
-
- * Recently we have declared that GIT_TEST_* variables take the
-   usual boolean values (it used to be that some used "non-empty
-   means true" and taking GIT_TEST_VAR=YesPlease as true); make
-   sure we notice and fail when non-bool strings are given to
-   these variables.
-
- * Users of oneway_merge() (like "reset --hard") learned to take
-   advantage of fsmonitor to avoid unnecessary lstat(2) calls.
-
- * Performance tweak on "git push" into a repository with many refs
-   that point at objects we have never heard of.
-
- * PerfTest fix to avoid stale result mixed up with the latest round
-   of test results.
-
- * Hide lower-level verify_signed-buffer() API as a pure helper to
-   implement the public check_signature() function, in order to
-   encourage new callers to use the correct and more strict
-   validation.
-
- * Unnecessary reading of state variables back from the disk during
-   sequencer operation has been reduced.
-
- * The code has been made to avoid gmtime() and localtime() and prefer
-   their reentrant counterparts.
-
- * In a repository with many packfiles, the cost of the procedure that
-   avoids registering the same packfile twice was unnecessarily high
-   by using an inefficient search algorithm, which has been corrected.
-
- * Redo "git name-rev" to avoid recursive calls.
-
- * FreeBSD CI support via Cirrus-CI has been added.
-
-
-Fixes since v2.24
------------------
-
- * "rebase -i" ceased to run post-commit hook by mistake in an earlier
-   update, which has been corrected.
-
- * "git notes copy $original" ought to copy the notes attached to the
-   original object to HEAD, but a mistaken tightening to command line
-   parameter validation made earlier disabled that feature by mistake.
-
- * When all files from some subdirectory were renamed to the root
-   directory, the directory rename heuristics would fail to detect that
-   as a rename/merge of the subdirectory to the root directory, which has
-   been corrected.
-
- * Code clean-up and a bugfix in the logic used to tell worktree local
-   and repository global refs apart.
-   (merge f45f88b2e4 sg/dir-trie-fixes later to maint).
-
- * "git stash save" in a working tree that is sparsely checked out
-   mistakenly removed paths that are outside the area of interest.
-   (merge 4a58c3d7f7 js/update-index-ignore-removal-for-skip-worktree later to maint).
-
- * "git rev-parse --git-path HEAD.lock" did not give the right path
-   when run in a secondary worktree.
-   (merge 76a53d640f js/git-path-head-dot-lock-fix later to maint).
-
- * "git merge --no-commit" needs "--no-ff" if you do not want to move
-   HEAD, which has been corrected in the manual page for "git bisect".
-   (merge 8dd327b246 ma/bisect-doc-sample-update later to maint).
-
- * "git worktree add" internally calls "reset --hard" that should not
-   descend into submodules, even when submodule.recurse configuration
-   is set, but it was affected.  This has been corrected.
-   (merge 4782cf2ab6 pb/no-recursive-reset-hard-in-worktree-add later to maint).
-
- * Messages from die() etc. can be mixed up from multiple processes
-   without even line buffering on Windows, which has been worked
-   around.
-   (merge 116d1fa6c6 js/vreportf-wo-buffering later to maint).
-
- * HTTP transport had possible allocator/deallocator mismatch, which
-   has been corrected.
-
- * The watchman integration for fsmonitor was racy, which has been
-   corrected to be more conservative.
-   (merge dd0b61f577 kw/fsmonitor-watchman-fix later to maint).
-
- * Fetching from multiple remotes into the same repository in parallel
-   had a bad interaction with the recent change to (optionally) update
-   the commit-graph after a fetch job finishes, as these parallel
-   fetches compete with each other.  Which has been corrected.
-
- * Recent update to "git stash pop" made the command empty the index
-   when run with the "--quiet" option, which has been corrected.
-
- * "git fetch" codepath had a big "do not lazily fetch missing objects
-   when I ask if something exists" switch.  This has been corrected by
-   marking the "does this thing exist?" calls with "if not please do not
-   lazily fetch it" flag.
-
- * Test update to avoid wasted cycles.
-   (merge e0316695ec sg/skip-skipped-prereq later to maint).
-
- * Error handling after "git push" finishes sending the packdata and
-   waits for the response to the remote side has been improved.
-   (merge ad7a403268 jk/send-pack-remote-failure later to maint).
-
- * Some codepaths in "gitweb" that forgot to escape URLs generated
-   based on end-user input have been corrected.
-   (merge a376e37b2c jk/gitweb-anti-xss later to maint).
-
- * CI jobs for macOS has been made less chatty when updating perforce
-   package used during testing.
-   (merge 0dbc4a0edf jc/azure-ci-osx-fix-fix later to maint).
-
- * "git unpack-objects" used to show progress based only on the number
-   of received and unpacked objects, which stalled when it has to
-   handle an unusually large object.  It now shows the throughput as
-   well.
-   (merge bae60ba7e9 sg/unpack-progress-throughput later to maint).
-
- * The sequencer machinery compared the HEAD and the state it is
-   attempting to commit to decide if the result would be a no-op
-   commit, even when amending a commit, which was incorrect, and
-   has been corrected.
-
- * The code to parse GPG output used to assume incorrectly that the
-   finterprint for the primary key would always be present for a valid
-   signature, which has been corrected.
-   (merge 67a6ea6300 hi/gpg-optional-pkfp-fix later to maint).
-
- * "git submodule status" and "git submodule status --cached" show
-   different things, but the documentation did not cover them
-   correctly, which has been corrected.
-   (merge 8d483c8408 mg/doc-submodule-status-cached later to maint).
-
- * "git reset --patch $object" without any pathspec should allow a
-   tree object to be given, but incorrectly required a committish,
-   which has been corrected.
-
- * "git submodule status" that is run from a subdirectory of the
-   superproject did not work well, which has been corrected.
-   (merge 1f3aea22c7 mg/submodule-status-from-a-subdirectory later to maint).
-
- * The revision walking machinery uses resources like per-object flag
-   bits that need to be reset before a new iteration of walking
-   begins, but the resources related to topological walk were not
-   cleared correctly, which has been corrected.
-   (merge 0aa0c2b2ec mh/clear-topo-walk-upon-reset later to maint).
-
- * TravisCI update.
-   (merge 176441bfb5 sg/osx-force-gcc-9 later to maint).
-
- * While running "revert" or "cherry-pick --edit" for multiple
-   commits, a recent regression incorrectly detected "nothing to
-   commit, working tree clean", instead of replaying the commits,
-   which has been corrected.
-   (merge befd4f6a81 sg/assume-no-todo-update-in-cherry-pick later to maint).
-
- * Work around a issue where a FD that is left open when spawning a
-   child process and is kept open in the child can interfere with the
-   operation in the parent process on Windows.
-
- * One kind of progress messages were always given during commit-graph
-   generation, instead of following the "if it takes more than two
-   seconds, show progress" pattern, which has been corrected.
-
- * "git rebase" did not work well when format.useAutoBase
-   configuration variable is set, which has been corrected.
-
- * The "diff" machinery learned not to lose added/removed blank lines
-   in the context when --ignore-blank-lines and --function-context are
-   used at the same time.
-   (merge 0bb313a552 rs/xdiff-ignore-ws-w-func-context later to maint).
-
- * The test on "fast-import" used to get stuck when "fast-import" died
-   in the middle.
-   (merge 0d9b0d7885 sg/t9300-robustify later to maint).
-
- * "git format-patch" can take a set of configured format.notes values
-   to specify which notes refs to use in the log message part of the
-   output.  The behaviour of this was not consistent with multiple
-   --notes command line options, which has been corrected.
-   (merge e0f9095aaa dl/format-patch-notes-config-fixup later to maint).
-
- * "git p4" used to ignore lfs.storage configuration variable, which
-   has been corrected.
-   (merge ea94b16fb8 rb/p4-lfs later to maint).
-
- * Assorted fixes to the directory traversal API.
-   (merge 6836d2fe06 en/fill-directory-fixes later to maint).
-
- * Forbid pathnames that the platform's filesystem cannot represent on
-   MinGW.
-   (merge 4dc42c6c18 js/mingw-reserved-filenames later to maint).
-
- * "git rebase --signoff" stopped working when the command was written
-   in C, which has been corrected.
-   (merge 4fe7e43c53 en/rebase-signoff-fix later to maint).
-
- * An earlier update to Git for Windows declared that a tree object is
-   invalid if it has a path component with backslash in it, which was
-   overly strict, which has been corrected.  The only protection the
-   Windows users need is to prevent such path (or any path that their
-   filesystem cannot check out) from entering the index.
-   (merge 224c7d70fa js/mingw-loosen-overstrict-tree-entry-checks later to maint).
-
- * The code to write split commit-graph file(s) upon fetching computed
-   bogus value for the parameter used in splitting the resulting
-   files, which has been corrected.
-   (merge 63020f175f ds/commit-graph-set-size-mult later to maint).

-Git 2.25.1 Release Notes
-========================
-
-Fixes since v2.25
------------------
-
- * "git commit" gives output similar to "git status" when there is
-   nothing to commit, but without honoring the advise.statusHints
-   configuration variable, which has been corrected.
-
- * has_object_file() said "no" given an object registered to the
-   system via pretend_object_file(), making it inconsistent with
-   read_object_file(), causing lazy fetch to attempt fetching an
-   empty tree from promisor remotes.
-
- * The code that tries to skip over the entries for the paths in a
-   single directory using the cache-tree was not careful enough
-   against corrupt index file.
-
- * Complete an update to tutorial that encourages "git switch" over
-   "git checkout" that was done only half-way.
-
- * Reduce unnecessary round-trip when running "ls-remote" over the
-   stateless RPC mechanism.
-
- * "git restore --staged" did not correctly update the cache-tree
-   structure, resulting in bogus trees to be written afterwards, which
-   has been corrected.
-
- * The code recently added to move to the entry beyond the ones in the
-   same directory in the index in the sparse-cone mode did not count
-   the number of entries to skip over incorrectly, which has been
-   corrected.
-
- * Work around test breakages caused by custom regex engine used in
-   libasan, when address sanitizer is used with more recent versions
-   of gcc and clang.
-
- * "git fetch --refmap=" option has got a better documentation.
-
- * Corner case bugs in "git clean" that stems from a (necessarily for
-   performance reasons) awkward calling convention in the directory
-   enumeration API has been corrected.
-
- * "git grep --no-index" should not get affected by the contents of
-   the .gitmodules file but when "--recurse-submodules" is given or
-   the "submodule.recurse" variable is set, it did.  Now these
-   settings are ignored in the "--no-index" mode.
-
- * Technical details of the bundle format has been documented.
-
- * Unhelpful warning messages during documentation build have been
-   squelched.
-
-Also contains various documentation updates, code clean-ups and minor fixups.

-Git 2.25.2 Release Notes
-========================
-
-Fixes since v2.25.1
--------------------
-
- * Minor bugfixes to "git add -i" that has recently been rewritten in C.
-
- * An earlier update to show the location of working tree in the error
-   message did not consider the possibility that a git command may be
-   run in a bare repository, which has been corrected.
-
- * The "--recurse-submodules" option of various subcommands did not
-   work well when run in an alternate worktree, which has been
-   corrected.
-
- * Running "git rm" on a submodule failed unnecessarily when
-   .gitmodules is only cache-dirty, which has been corrected.
-
- * "git rebase -i" identifies existing commits in its todo file with
-   their abbreviated object name, which could become ambigous as it
-   goes to create new commits, and has a mechanism to avoid ambiguity
-   in the main part of its execution.  A few other cases however were
-   not covered by the protection against ambiguity, which has been
-   corrected.
-
- * The index-pack code now diagnoses a bad input packstream that
-   records the same object twice when it is used as delta base; the
-   code used to declare a software bug when encountering such an
-   input, but it is an input error.
-
- * The code to automatically shrink the fan-out in the notes tree had
-   an off-by-one bug, which has been killed.
-
- * "git check-ignore" did not work when the given path is explicitly
-   marked as not ignored with a negative entry in the .gitignore file.
-
- * The merge-recursive machinery failed to refresh the cache entry for
-   a merge result in a couple of places, resulting in an unnecessary
-   merge failure, which has been fixed.
-
- * Fix for a bug revealed by a recent change to make the protocol v2
-   the default.
-
- * "git merge signed-tag" while lacking the public key started to say
-   "No signature", which was utterly wrong.  This regression has been
-   reverted.
-
- * MinGW's poll() emulation has been improved.
-
- * "git show" and others gave an object name in raw format in its
-   error output, which has been corrected to give it in hex.
-
- * Both "git ls-remote -h" and "git grep -h" give short usage help,
-   like any other Git subcommand, but it is not unreasonable to expect
-   that the former would behave the same as "git ls-remote --head"
-   (there is no other sensible behaviour for the latter).  The
-   documentation has been updated in an attempt to clarify this.
-
-Also contains various documentation updates, code clean-ups and minor fixups.

-Git 2.26 Release Notes
-======================
-
-Updates since v2.25
--------------------
-
-Backward compatibility notes
-
- * "git rebase" uses a different backend that is based on the 'merge'
-   machinery by default.  There are a few known differences in the
-   behaviour from the traditional machinery based on patch+apply.
-
-   If your workflow is negatively affected by this change, please
-   report it to git@vger.kernel.org so that we can take a look into
-   it.  After doing so, you can set the 'rebase.backend' configuration
-   variable to 'apply', in order to use the old default behaviour in
-   the meantime.
-
-
-UI, Workflows & Features
-
- * Sample credential helper for using .netrc has been updated to work
-   out of the box.
-
- * gpg.minTrustLevel configuration variable has been introduced to
-   tell various signature verification codepaths the required minimum
-   trust level.
-
- * The command line completion (in contrib/) learned to complete
-   subcommands and arguments to "git worktree".
-
- * Disambiguation logic to tell revisions and pathspec apart has been
-   tweaked so that backslash-escaped glob special characters do not
-   count in the "wildcards are pathspec" rule.
-
- * One effect of specifying where the GIT_DIR is (either with the
-   environment variable, or with the "git --git-dir=<where> cmd"
-   option) is to disable the repository discovery.  This has been
-   placed a bit more stress in the documentation, as new users often
-   get confused.
-
- * Two help messages given when "git add" notices the user gave it
-   nothing to add have been updated to use advise() API.
-
- * A new version of fsmonitor-watchman hook has been introduced, to
-   avoid races.
-
- * "git config" learned to show in which "scope", in addition to in
-   which file, each config setting comes from.
-
- * The basic 7 colors learned the brighter counterparts
-   (e.g. "brightred").
-
- * "git sparse-checkout" learned a new "add" subcommand.
-
- * A configuration element used for credential subsystem can now use
-   wildcard pattern to specify for which set of URLs the entry
-   applies.
-
- * "git clone --recurse-submodules --single-branch" now uses the same
-   single-branch option when cloning the submodules.
-
- * "git rm" and "git stash" learns the new "--pathspec-from-file"
-   option.
-
- * "git am --show-current-patch" is a way to show the piece of e-mail
-   for the stopped step, which is not suitable to directly feed "git
-   apply" (it is designed to be a good "git am" input).  It learned a
-   new option to show only the patch part.
-
- * Handling of conflicting renames in merge-recursive have further
-   been made consistent with how existing codepaths try to mimic what
-   is done to add/add conflicts.
-
-
-Performance, Internal Implementation, Development Support etc.
-
- * Tell .editorconfig that in this project, *.txt files are indented
-   with tabs.
-
- * The test-lint machinery knew to check "VAR=VAL shell_function"
-   construct, but did not check "VAR= shell_function", which has been
-   corrected.
-
- * Replace "git config --bool" calls with "git config --type=bool" in
-   sample templates.
-
- * The effort to move "git-add--interactive" to C continues.
-
- * Improve error message generation for "git submodule add".
-
- * Preparation of test scripts for the day when the object names will
-   use SHA-256 continues.
-
- * Warn programmers about pretend_object_file() that allows the code
-   to tentatively use in-core objects.
-
- * The way "git pack-objects" reuses objects stored in existing pack
-   to generate its result has been improved.
-
- * The transport protocol version 2 becomes the default one.
-
- * Traditionally, we avoided threaded grep while searching in objects
-   (as opposed to files in the working tree) as accesses to the object
-   layer is not thread-safe.  This limitation is getting lifted.
-
- * "git rebase -i" (and friends) used to unnecessarily check out the
-   tip of the branch to be rebased, which has been corrected.
-
- * A low-level API function get_oid(), that accepts various ways to
-   name an object, used to issue end-user facing error messages
-   without l10n, which has been updated to be translatable.
-
- * Unneeded connectivity check is now disabled in a partial clone when
-   fetching into it.
-
- * Some rough edges in the sparse-checkout feature, especially around
-   the cone mode, have been cleaned up.
-
- * The diff-* plumbing family of subcommands now pay attention to the
-   diff.wsErrorHighlight configuration, which has been ignored before;
-   this allows "git add -p" to also show the whitespace problems to
-   the end user.
-
- * Some codepaths were given a repository instance as a parameter to
-   work in the repository, but passed the_repository instance to its
-   callees, which has been cleaned up (somewhat).
-
- * Memory footprint and performance of "git name-rev" has been
-   improved.
-
- * The object reachability bitmap machinery and the partial cloning
-   machinery were not prepared to work well together, because some
-   object-filtering criteria that partial clones use inherently rely
-   on object traversal, but the bitmap machinery is an optimization
-   to bypass that object traversal.  There however are some cases
-   where they can work together, and they were taught about them.
-
- * "git rebase" has learned to use the merge backend (i.e. the
-   machinery that drives "rebase -i") by default, while allowing
-   "--apply" option to use the "apply" backend (e.g. the moral
-   equivalent of "format-patch piped to am").  The rebase.backend
-   configuration variable can be set to customize.
-
- * Underlying machinery of "git bisect--helper" is being refactored
-   into pieces that are more easily reused.
-
-
-Fixes since v2.25
------------------
-
- * "git commit" gives output similar to "git status" when there is
-   nothing to commit, but without honoring the advise.statusHints
-   configuration variable, which has been corrected.

- * The code recently added to move to the entry beyond the ones in the
-   same directory in the index in the sparse-cone mode did not count
-   the number of entries to skip over incorrectly, which has been
-   corrected.
-
- * Rendering by "git log --graph" of ancestry lines leading to a merge
-   commit were made suboptimal to waste vertical space a bit with a
-   recent update, which has been corrected.
-
- * Work around test breakages caused by custom regex engine used in
-   libasan, when address sanitizer is used with more recent versions
-   of gcc and clang.
-
- * Minor bugfixes to "git add -i" that has recently been rewritten in C.
-
- * "git fetch --refmap=" option has got a better documentation.
-
- * "git checkout X" did not correctly fail when X is not a local
-   branch but could name more than one remote-tracking branches
-   (i.e. to be dwimmed as the starting point to create a corresponding
-   local branch), which has been corrected.
-   (merge fa74180d08 am/checkout-file-and-ref-ref-ambiguity later to maint).
-
- * Corner case bugs in "git clean" that stems from a (necessarily for
-   performance reasons) awkward calling convention in the directory
-   enumeration API has been corrected.
-
- * A fetch that is told to recursively fetch updates in submodules
-   inevitably produces reams of output, and it becomes hard to spot
-   error messages.  The command has been taught to enumerate
-   submodules that had errors at the end of the operation.
-   (merge 0222540827 es/fetch-show-failed-submodules-atend later to maint).
-
- * The "--recurse-submodules" option of various subcommands did not

-   detail.
-
- * Running "git rm" on a submodule failed unnecessarily when
-   .gitmodules is only cache-dirty, which has been corrected.
-
- * C pedantry ;-) fix.
-
- * "git grep --no-index" should not get affected by the contents of
-   the .gitmodules file but when "--recurse-submodules" is given or
-   the "submodule.recurse" variable is set, it did.  Now these
-   settings are ignored in the "--no-index" mode.
-
- * Technical details of the bundle format has been documented.
-
- * Unhelpful warning messages during documentation build have been squelched.
-
- * "git rebase -i" identifies existing commits in its todo file with
-   their abbreviated object name, which could become ambiguous as it
-   goes to create new commits, and has a mechanism to avoid ambiguity
-   in the main part of its execution.  A few other cases however were
-   not covered by the protection against ambiguity, which has been
-   corrected.
-
- * Allow the rebase.missingCommitsCheck configuration to kick in when
-   "rebase --edit-todo" and "rebase --continue" restarts the procedure.
-   (merge 5a5445d878 ag/edit-todo-drop-check later to maint).
-
- * The way "git submodule status" reports an initialized but not yet
-   populated submodule has not been reimplemented correctly when a
-   part of the "git submodule" command was rewritten in C, which has
-   been corrected.
-   (merge f38c92452d pk/status-of-uncloned-submodule later to maint).
-
- * The code to automatically shrink the fan-out in the notes tree had
-   an off-by-one bug, which has been killed.
-
- * The index-pack code now diagnoses a bad input packstream that
-   records the same object twice when it is used as delta base; the
-   code used to declare a software bug when encountering such an
-   input, but it is an input error.
-
-
- * The code to compute the commit-graph has been taught to use a more
-   robust way to tell if two object directories refer to the same
-   thing.
-   (merge a7df60cac8 tb/commit-graph-object-dir later to maint).
-
- * "git remote rename X Y" needs to adjust configuration variables
-   (e.g. branch.<name>.remote) whose value used to be X to Y.
-   branch.<name>.pushRemote is now also updated.
-
- * Update to doc-diff.
-
- * Doc markup fix.
-
- * "git check-ignore" did not work when the given path is explicitly
-   marked as not ignored with a negative entry in the .gitignore file.
-
- * The merge-recursive machinery failed to refresh the cache entry for
-   a merge result in a couple of places, resulting in an unnecessary
-   merge failure, which has been fixed.
-
- * Fix for a bug revealed by a recent change to make the protocol v2
-   the default.
-
- * In rare cases "git worktree add <path>" could think that <path>
-   was already a registered worktree even when it wasn't and refuse
-   to add the new worktree. This has been corrected.
-   (merge bb69b3b009 es/worktree-avoid-duplication-fix later to maint).
-
- * "git push" should stop from updating a branch that is checked out
-   when receive.denyCurrentBranch configuration is set, but it failed
-   to pay attention to checkouts in secondary worktrees.  This has
-   been corrected.
-   (merge 4d864895a2 hv/receive-denycurrent-everywhere later to maint).
-
- * "git rebase BASE BRANCH" rebased/updated the tip of BRANCH and
-   checked it out, even when the BRANCH is checked out in a different
-   worktree.  This has been corrected.
-   (merge b5cabb4a96 es/do-not-let-rebase-switch-to-protected-branch later to maint).
-
- * "git describe" in a repository with multiple root commits sometimes
-   gave up looking for the best tag to describe a given commit with
-   too early, which has been adjusted.
-
- * "git merge signed-tag" while lacking the public key started to say
-   "No signature", which was utterly wrong.  This regression has been
-   reverted.
-
- * MinGW's poll() emulation has been improved.
-
- * "git show" and others gave an object name in raw format in its
-   error output, which has been corrected to give it in hex.
-
- * "git fetch" over HTTP walker protocol did not show any progress
-   output.  We inherently do not know how much work remains, but still
-   we can show something not to bore users.
-   (merge 7655b4119d rs/show-progress-in-dumb-http-fetch later to maint).
-
- * Both "git ls-remote -h" and "git grep -h" give short usage help,
-   like any other Git subcommand, but it is not unreasonable to expect
-   that the former would behave the same as "git ls-remote --head"
-   (there is no other sensible behaviour for the latter).  The
-   documentation has been updated in an attempt to clarify this.
-
- * Other code cleanup, docfix, build fix, etc.

-Git 2.27 Release Notes
-======================
-
-Updates since v2.26
--------------------
-
-Backward compatibility notes
-
- * When "git describe C" finds that commit C is pointed by a signed or
-   annotated tag, which records T as its tagname in the object, the
-   command gives T as its answer.  Even if the user renames or moves
-   such a tag from its natural location in the "refs/tags/" hierarchy,
-   "git describe C" would still give T as the answer, but in such a
-   case "git show T^0" would no longer work as expected.  There may be
-   nothing at "refs/tags/T" or even worse there may be a different tag
-   instead.
-
-   Starting from this version, "git describe" will always use the
-   "long" version, as if the "--long" option were given, when giving
-   its output based on such a misplaced tag to work around the problem.
-
- * "git pull" issues a warning message until the pull.rebase
-   configuration variable is explicitly given, which some existing
-   users may find annoying---those who prefer not to rebase need to
-   set the variable to false to squelch the warning.
-
- * The transport protocol version 2, which was promoted to the default
-   in Git 2.26 release, turned out to have some remaining rough edges,
-   so it has been demoted from the default.
-
-
-UI, Workflows & Features
-
- * A handful of options to configure SSL when talking to proxies have
-   been added.
-
- * Smudge/clean conversion filters are now given more information
-   (e.g. the object of the tree-ish in which the blob being converted
-   appears, in addition to its path, which has already been given).
-
- * When "git describe C" finds an annotated tag with tagname A to be
-   the best name to explain commit C, and the tag is stored in a
-   "wrong" place in the refs/tags hierarchy, e.g. refs/tags/B, the
-   command gave a warning message but used A (not B) to describe C.
-   If C is exactly at the tag, the describe output would be "A", but
-   "git rev-parse A^0" would not be equal as "git rev-parse C^0".  The
-   behavior of the command has been changed to use the "long" form
-   i.e. A-0-gOBJECTNAME, which is correctly interpreted by rev-parse.
-
- * "git pull" learned to warn when no pull.rebase configuration
-   exists, and neither --[no-]rebase nor --ff-only is given (which
-   would result a merge).
-
- * "git p4" learned four new hooks and also "--no-verify" option to
-   bypass them (and the existing "p4-pre-submit" hook).
-
- * "git pull" shares many options with underlying "git fetch", but
-   some of them were not documented and some of those that would make
-   sense to pass down were not passed down.
-
- * "git rebase" learned the "--no-gpg-sign" option to countermand
-   commit.gpgSign the user may have.
-
- * The output from "git format-patch" uses RFC 2047 encoding for
-   non-ASCII letters on From: and Subject: headers, so that it can
-   directly be fed to e-mail programs.  A new option has been added
-   to produce these headers in raw.
-
- * "git log" learned "--show-pulls" that helps pathspec limited
-   history views; a merge commit that takes the whole change from a
-   side branch, which is normally omitted from the output, is shown
-   in addition to the commits that introduce real changes.
-
- * The interactive input from various codepaths are consolidated and
-   any prompt possibly issued earlier are fflush()ed before we read.
-
- * Allow "git rebase" to reapply all local commits, even if the may be
-   already in the upstream, without checking first.
-
- * The 'pack.useSparse' configuration variable now defaults to 'true',
-   enabling an optimization that has been experimental since Git 2.21.
-
- * "git rebase" happens to call some hooks meant for "checkout" and
-   "commit" by this was not a designed behaviour than historical
-   accident.  This has been documented.
-
- * "git merge" learns the "--autostash" option.
-
- * "sparse-checkout" UI improvements.
-
- * "git update-ref --stdin" learned a handful of new verbs to let the
-   user control ref update transactions more explicitly, which helps
-   as an ingredient to implement two-phase commit-style atomic
-   ref-updates across multiple repositories.
-
- * "git commit-graph write" learned different ways to write out split
-   files.
-
- * Introduce an extension to the commit-graph to make it efficient to
-   check for the paths that were modified at each commit using Bloom
-   filters.
-
- * The approxidate parser learns to parse seconds with fraction and
-   ignore fractional part.
-
- * The userdiff patterns for Markdown documents have been added.
-
- * The sparse-checkout patterns have been forbidden from excluding all
-   paths, leaving an empty working tree, for a long time.  This
-   limitation has been lifted.
-
- * "git restore --staged --worktree" now defaults to take the contents
-   out of "HEAD", instead of erring out.
-
- * "git p4" learned to recover from a (broken) state where a directory
-   and a file are recorded at the same path in the Perforce repository
-   the same way as their clients do.
-
- * "git multi-pack-index repack" has been taught to honor some
-   repack.* configuration variables.
-
-
-Performance, Internal Implementation, Development Support etc.
-
- * The advise API has been revamped to allow more systematic enumeration of
-   advice knobs in the future.
-
- * SHA-256 transition continues.
-
- * The code to interface with GnuPG has been refactored.
-
- * "git stash" has kept an escape hatch to use the scripted version
-   for a few releases, which got stale.  It has been removed.
-
- * Enable tests that require GnuPG on Windows.
-
- * Minor test usability improvement.
-
- * Trace2 enhancement to allow logging of the environment variables.
-
- * Test clean-up continues.
-
- * Perf-test update.
-
- * A Windows-specific test element has been made more robust against
-   misuse from both user's environment and programmer's errors.
-
- * Various tests have been updated to work around issues found with
-   shell utilities that come with busybox etc.
-
- * The config API made mixed uses of int and size_t types to represent
-   length of various pieces of text it parsed, which has been updated
-   to use the correct type (i.e. size_t) throughout.
-
- * The "--decorate-refs" and "--decorate-refs-exclude" options "git
-   log" takes have learned a companion configuration variable
-   log.excludeDecoration that sits at the lowest priority in the
-   family.
-
- * A new CI job to build and run test suite on linux with musl libc
-   has been added.
-
- * Update the CI configuration to use GitHub Actions, retiring the one
-   based on Azure Pipelines.
-
- * The directory traversal code had redundant recursive calls which
-   made its performance characteristics exponential with respect to
-   the depth of the tree, which was corrected.
-
- * "git blame" learns to take advantage of the "changed-paths" Bloom
-   filter stored in the commit-graph file.
-
- * The "bugreport" tool has been added.
-
- * The object walk with object filter "--filter=tree:0" can now take
-   advantage of the pack bitmap when available.
-
- * Instead of always building all branches at GitHub via Actions,
-   users can specify which branches to build.
-
- * Codepaths that show progress meter have been taught to also use the
-   start_progress() and the stop_progress() calls as a "region" to be
-   traced.
-
- * Instead of downloading Windows SDK for CI jobs for windows builds
-   from an external site (wingit.blob.core.windows.net), use the one
-   created in the windows-build job, to work around quota issues at
-   the external site.
-
-
-Fixes since v2.26
------------------
-
- * The real_path() convenience function can easily be misused; with a
-   bit of code refactoring in the callers' side, its use has been
-   eliminated.
-   (merge 49d3c4b481 am/real-path-fix later to maint).
-
- * Update "git p4" to work with Python 3.
-   (merge 6bb40ed20a yz/p4-py3 later to maint).
-
- * The mechanism to prevent "git commit" from making an empty commit
-   or amending during an interrupted cherry-pick was broken during the
-   rewrite of "git rebase" in C, which has been corrected.
-   (merge 430b75f720 pw/advise-rebase-skip later to maint).
-
- * Fix "git checkout --recurse-submodules" of a nested submodule
-   hierarchy.
-   (merge 846f34d351 pb/recurse-submodules-fix later to maint).
-
- * The "--fork-point" mode of "git rebase" regressed when the command
-   was rewritten in C back in 2.20 era, which has been corrected.
-   (merge f08132f889 at/rebase-fork-point-regression-fix later to maint).
-
- * The import-tars importer (in contrib/fast-import/) used to create
-   phony files at the top-level of the repository when the archive
-   contains global PAX headers, which made its own logic to detect and
-   omit the common leading directory ineffective, which has been
-   corrected.
-   (merge c839fcff65 js/import-tars-do-not-make-phony-files-from-pax-headers later to maint).
-
- * Simplify the commit ancestry connectedness check in a partial clone
-   repository in which "promised" objects are assumed to be obtainable
-   lazily on-demand from promisor remote repositories.
-   (merge 2b98478c6f jt/connectivity-check-optim-in-partial-clone later to maint).
-
- * The server-end of the v2 protocol to serve "git clone" and "git
-   fetch" was not prepared to see a delim packets at unexpected
-   places, which led to a crash.
-   (merge cacae4329f jk/harden-protocol-v2-delim-handling later to maint).
-
- * When fed a midx that records no objects, some codepaths tried to
-   loop from 0 through (num_objects-1), which, due to integer
-   arithmetic wrapping around, made it nonsense operation with out of
-   bounds array accesses.  The code has been corrected to reject such
-   an midx file.
-   (merge 796d61cdc0 dr/midx-avoid-int-underflow later to maint).
-
- * Utitiles run via the run_command() API were not spawned correctly
-   on Cygwin, when the paths to them are given as a full path with
-   backslashes.
-   (merge 05ac8582bc ak/run-command-on-cygwin-fix later to maint).
-
- * "git pull --rebase" tried to run a rebase even after noticing that
-   the pull results in a fast-forward and no rebase is needed nor
-   sensible, for the past few years due to a mistake nobody noticed.
-   (merge fbae70ddc6 en/pull-do-not-rebase-after-fast-forwarding later to maint).
-
- * "git rebase" with the merge backend did not work well when the
-   rebase.abbreviateCommands configuration was set.
-   (merge de9f1d3ef4 ag/rebase-merge-allow-ff-under-abbrev-command later to maint).
-
- * The logic to auto-follow tags by "git clone --single-branch" was
-   not careful to avoid lazy-fetching unnecessary tags, which has been
-   corrected.
-   (merge 167a575e2d jk/use-quick-lookup-in-clone-for-tag-following later to maint).
-
- * "git rebase -i" did not leave the reflog entries correctly.
-   (merge 1f6965f994 en/sequencer-reflog-action later to maint).
-
- * The more aggressive updates to remote-tracking branches we had for
-   the past 7 years or so were not reflected in the documentation,
-   which has been corrected.
-   (merge a44088435c pb/pull-fetch-doc later to maint).
-
- * We've left the command line parsing of "git log :/a/b/" broken for
-   about a full year without anybody noticing, which has been
-   corrected.
-   (merge 0220461071 jc/missing-ref-store-fix later to maint).
-
- * Misc fixes for Windows.
-   (merge 3efc128cd5 js/mingw-fixes later to maint).
-
- * "git rebase" (again) learns to honor "--no-keep-empty", which lets
-   the user to discard commits that are empty from the beginning (as
-   opposed to the ones that become empty because of rebasing).  The
-   interactive rebase also marks commits that are empty in the todo.
-   (merge 50ed76148a en/rebase-no-keep-empty later to maint).
-
- * Parsing the host part out of URL for the credential helper has been corrected.
-   (merge 4c5971e18a jk/credential-parsing-end-of-host-in-URL later to maint).
-
- * Document the recommended way to abort a failing test early (e.g. by
-   exiting a loop), which is to say "return 1".
-   (merge 7cc112dc95 jc/doc-test-leaving-early later to maint).
-
- * The code that refreshes the last access and modified time of
-   on-disk packfiles and loose object files have been updated.
-   (merge 312cd76130 lr/freshen-file-fix later to maint).
-
- * Validation of push certificate has been made more robust against
-   timing attacks.
-   (merge 719483e547 bc/constant-memequal later to maint).
-
- * The custom hash function used by "git fast-import" has been
-   replaced with the one from hashmap.c, which gave us a nice
-   performance boost.
-   (merge d8410a816b jk/fast-import-use-hashmap later to maint).
-
- * The "git submodule" command did not initialize a few variables it
-   internally uses and was affected by variable settings leaked from
-   the environment.
-   (merge 65d100c4dd lx/submodule-clear-variables later to maint).
-
- * Raise the minimum required version of docbook-xsl package to 1.74,
-   as 1.74.0 was from late 2008, which is more than 10 years old, and
-   drop compatibility cruft from our documentation suite.
-   (merge 3c255ad660 ma/doc-discard-docbook-xsl-1.73 later to maint).
-
- * "git log" learns "--[no-]mailmap" as a synonym to "--[no-]use-mailmap"
-   (merge 88acccda38 jc/log-no-mailmap later to maint).
-
- * "git commit-graph write --expire-time=<timestamp>" did not use the
-   given timestamp correctly, which has been corrected.
-   (merge b09b785c78 ds/commit-graph-expiry-fix later to maint).
-
- * Tests update to use "test-chmtime" instead of "touch -t".
-   (merge e892a56845 ds/t5319-touch-fix later to maint).
-
- * "git diff" in a partial clone learned to avoid lazy loading blob
-   objects in more casese when they are not needed.
-   (merge 95acf11a3d jt/avoid-prefetch-when-able-in-diff later to maint).
-
- * "git push --atomic" used to show failures for refs that weren't
-   even pushed, which has been corrected.
-   (merge dfe1b7f19c jx/atomic-push later to maint).
-
- * Code in builtin/*, i.e. those can only be called from within
-   built-in subcommands, that implements bulk of a couple of
-   subcommands have been moved to libgit.a so that they could be used
-   by others.
-   (merge 9460fd48b5 dl/libify-a-few later to maint).
-
- * Allowing the user to split a patch hunk while "git stash -p" does
-   not work well; a band-aid has been added to make this (partially)
-   work better.
-
- * "git diff-tree --pretty --notes" used to hit an assertion failure,
-   as it forgot to initialize the notes subsystem.
-   (merge 5778b22b3d tb/diff-tree-with-notes later to maint).
-
- * "git range-diff" fixes.
-   (merge 8d1675eb7f vd/range-diff-with-custom-pretty-format-fix later to maint).
-
- * "git grep" did not quote a path with unusual character like other
-   commands (like "git diff", "git status") do, but did quote when run
-   from a subdirectory, both of which has been corrected.
-   (merge 45115d8490 mt/grep-cquote-path later to maint).
-
- * GNU/Hurd is also among the ones that need the fopen() wrapper.
-   (merge 274a1328fb jc/gnu-hurd-lets-fread-read-dirs later to maint).
-
- * Those fetching over protocol v2 from linux-next and other kernel
-   repositories are reporting that v2 often fetches way too much than
-   needed.
-   (merge 11c7f2a30b jn/demote-proto2-from-default later to maint).
-
- * The upload-pack protocol v2 gave up too early before finding a
-   common ancestor, resulting in a wasteful fetch from a fork of a
-   project.  This has been corrected to match the behaviour of v0
-   protocol.
-   (merge 2f0a093dd6 jt/v2-fetch-nego-fix later to maint).
-
- * The build procedure did not use the libcurl library and its include
-   files correctly for a custom-built installation.
-   (merge 0573831950 jk/build-with-right-curl later to maint).
-
- * Tighten "git mailinfo" to notice and error out when decoded result
-   contains NUL in it.
-   (merge 3919997447 dd/mailinfo-with-nul later to maint).
-
- * Fix in-core inconsistency after fetching into a shallow repository
-   that broke the code to write out commit-graph.
-   (merge 37b9dcabfc tb/reset-shallow later to maint).
-
- * The commit-graph code exhausted file descriptors easily when it
-   does not have to.
-   (merge c8828530b7 tb/commit-graph-fd-exhaustion-fix later to maint).
-
- * The multi-pack-index left mmapped file descriptors open when it
-   does not have to.
-   (merge 6c7ff7cf7f ds/multi-pack-index later to maint).
-
- * Recent update to Homebrew used by macOS folks breaks build by
-   moving gettext library and necessary headers.
-   (merge a0b3108618 ds/build-homebrew-gettext-fix later to maint).
-
- * Incompatible options "--root" and "--fork-point" of "git rebase"
-   have been marked and documented as being incompatible.
-   (merge a35413c378 en/rebase-root-and-fork-point-are-incompatible later to maint).
-
- * Error and verbose trace messages from "git push" did not redact
-   credential material embedded in URLs.
-   (merge d192fa5006 js/anonymise-push-url-in-errors later to maint).
-
- * Update the parser used for credential.<URL>.<variable>
-   configuration, to handle <URL>s with '/' in them correctly.
-   (merge b44d0118ac bc/wildcard-credential later to maint).
-
- * Recent updates broke parsing of "credential.<url>.<key>" where

-
- * "git branch" and other "for-each-ref" variants accepted multiple

-   with the refname, which have been fixed.

-
- * The coding guideline for shell scripts instructed to refer to a
-   variable with dollar-sign inside arithmetic expansion to work
-   around a bug in old versions of dash, which is a thing of the past.
-   Now we are not forbidden from writing $((var+1)).
-   (merge 32b5fe7f0e jk/arith-expansion-coding-guidelines later to maint).
-
- * The <stdlib.h> header on NetBSD brings in its own definition of

-   around the issue.

-   the "--quiet" option, to pass "--quiet" down to "gc --auto".
-   (merge 7c3e9e8cfb jc/auto-gc-quiet later to maint).
-
- * The code to skip unmerged paths in the index when sparse checkout
-   is in use would have made out-of-bound access of the in-core index
-   when the last path was unmerged, which has been corrected.
-
- * Serving a "git fetch" client over "git://" and "ssh://" protocols
-   using the on-wire protocol version 2 was buggy on the server end
-   when the client needs to make a follow-up request to
-   e.g. auto-follow tags.

- * "rebase -i" segfaulted when rearranging a sequence that has a

-   fix-up of yet another step).
-   (merge 02471e7e20 js/rebase-autosquash-double-fixup-fix later to maint).
-
- * "git fsck" ensures that the paths recorded in tree objects are
-   sorted and without duplicates, but it failed to notice a case where

-   name.  This has been corrected.

-Git 2.28 Release Notes
-======================
-
-Updates since v2.27
--------------------
-
-Backward compatibility notes
-
- * "fetch.writeCommitGraph" is deemed to be still a bit too risky and
-   is no longer part of the "feature.experimental" set.
-
- * It used to be that setting extensions.* configuration variables
-   alone, while leaving core.repositoryFormatVersion=0, made these
-   settings effective, which was a wrong thing to do.  In version 0,
-   there was no special meaning in extensions.* configuration
-   variables.  This has been corrected.  If you need these repository
-   extensions to be effective, the core.repositoryFormatVersion
-   variable needs to be updated to 1 after vetting these extensions.*
-   variables are set correctly.
-
-
-UI, Workflows & Features
-
- * The commands in the "diff" family learned to honor "diff.relative"
-   configuration variable.
-
- * The check in "git fsck" to ensure that the tree objects are sorted
-   still had corner cases it missed unsorted entries.
-
- * The interface to redact sensitive information in the trace output
-   has been simplified.
-
- * The command line completion (in contrib/) learned to complete
-   options that the "git switch" command takes.
-
- * "git diff" used to take arguments in random and nonsense range
-   notation, e.g. "git diff A..B C", "git diff A..B C...D", etc.,
-   which has been cleaned up.
-
- * "git diff-files" has been taught to say paths that are marked as
-   intent-to-add are new files, not modified from an empty blob.
-
- * "git status" learned to report the status of sparse checkout.
-
- * "git difftool" has trouble dealing with paths added to the index
-   with the intent-to-add bit.
-
- * "git fast-export --anonymize" learned to take customized mapping to
-   allow its users to tweak its output more usable for debugging.
-
- * The command line completion support (in contrib/) used to be
-   prepared to work with "set -u" but recent changes got a bit more
-   sloppy.  This has been corrected.
-
-
-Performance, Internal Implementation, Development Support etc.
-
- * Code optimization for a common case.
-   (merge 8777616e4d an/merge-single-strategy-optim later to maint).
-
- * We've adopted a convention that any on-stack structure can be
-   initialized to have zero values in all fields with "= { 0 }",
-   even when the first field happens to be a pointer, but sparse
-   complained that a null pointer should be spelled NULL for a long
-   time.  Start using -Wno-universal-initializer option to squelch
-   it (the latest sparse has it on by default).
-
- * "git log -L..." now takes advantage of the "which paths are touched
-   by this commit?" info stored in the commit-graph system.
-
- * As FreeBSD is not the only platform whose regexp library reports
-   a REG_ILLSEQ error when fed invalid UTF-8, add logic to detect that
-   automatically and skip the affected tests.
-
- * "git bugreport" learns to report what shell is in use.
-
- * Support for GIT_CURL_VERBOSE has been rewritten in terms of
-   GIT_TRACE_CURL.
-
- * Preliminary clean-ups around refs API, plus file format
-   specification documentation for the reftable backend.
-
- * Workaround breakage in MSVC build, where "curl-config --cflags"
-   gives settings appropriate for GCC build.
-
- * Code clean-up of "git clean" resulted in a fix of recent
-   performance regression.
-
- * Code clean-up in the codepath that serves "git fetch" continues.
-
- * "git merge-base --is-ancestor" is taught to take advantage of the
-   commit graph.
-
- * Rewrite of parts of the scripted "git submodule" Porcelain command
-   continues; this time it is "git submodule set-branch" subcommand's
-   turn.
-
- * The "fetch/clone" protocol has been updated to allow the server to
-   instruct the clients to grab pre-packaged packfile(s) in addition
-   to the packed object data coming over the wire.
-
- * A misdesigned strbuf_write_fd() function has been retired.
-
- * SHA-256 migration work continues, including CVS/SVN interface.
-
- * A few fields in "struct commit" that do not have to always be
-   present have been moved to commit slabs.
-
- * API cleanup for get_worktrees()
-
- * By renumbering object flag bits, "struct object" managed to lose
-   bloated inter-field padding.
-
- * The name of the primary branch in existing repositories, and the
-   default name used for the first branch in newly created
-   repositories, is made configurable, so that we can eventually wean
-   ourselves off of the hardcoded 'master'.
-
- * The effort to avoid using test_must_fail on non-git command continues.
-
- * In 2.28-rc0, we corrected a bug that some repository extensions are
-   honored by mistake even in a version 0 repositories (these
-   configuration variables in extensions.* namespace were supposed to
-   have special meaning in repositories whose version numbers are 1 or
-   higher), but this was a bit too big a change.  The behaviour in
-   recent versions of Git where certaion extensions.* were honored by
-   mistake even in version 0 repositories has been restored.
-
-
-Fixes since v2.27
------------------
-
- * The "--prepare-p4-only" option of "git p4" is supposed to stop
-   after replaying one changeset, but kept going (by mistake?)
-
- * The error message from "git checkout -b foo -t bar baz" was
-   confusing.
-
- * Some repositories in the wild have commits that record nonsense
-   committer timezone (e.g. rails.git); "git fast-import" learned an
-   option to pass these nonsense timestamps intact to allow recreating
-   existing repositories as-is.
-   (merge d42a2fb72f en/fast-import-looser-date later to maint).
-
- * The command line completion script (in contrib/) tried to complete
-   "git stash -p" as if it were "git stash push -p", but it was too
-   aggressive and also affected "git stash show -p", which has been
-   corrected.
-   (merge fffd0cf520 vs/complete-stash-show-p-fix later to maint).
-
- * On-the-wire protocol v2 easily falls into a deadlock between the
-   remote-curl helper and the fetch-pack process when the server side
-   prematurely throws an error and disconnects.  The communication has
-   been updated to make it more robust.
-
- * "git checkout -p" did not handle a newly added path at all.
-   (merge 2c8bd8471a js/checkout-p-new-file later to maint).
-
- * The code to parse "git bisect start" command line was lax in
-   validating the arguments.
-   (merge 4d9005ff5d cb/bisect-helper-parser-fix later to maint).
-
- * Reduce memory usage during "diff --quiet" in a worktree with too
-   many stat-unmatched paths.
-   (merge d2d7fbe129 jk/diff-memuse-optim-with-stat-unmatch later to maint).
-
- * The reflog entries for "git clone" and "git fetch" did not
-   anonymize the URL they operated on.
-   (merge 46da295a77 js/reflog-anonymize-for-clone-and-fetch later to maint).
-
- * The behaviour of "sparse-checkout" in the state "git clone
-   --no-checkout" left was changed accidentally in 2.27, which has
-   been corrected.
-
- * Use of negative pathspec, while collecting paths including
-   untracked ones in the working tree, was broken.
-
- * The same worktree directory must be registered only once, but
-   "git worktree move" allowed this invariant to be violated, which
-   has been corrected.
-   (merge 810382ed37 es/worktree-duplicate-paths later to maint).
-
- * The effect of sparse checkout settings on submodules is documented.
-   (merge e7d7c73249 en/sparse-with-submodule-doc later to maint).
-
- * Code clean-up around "git branch" with a minor bugfix.
-   (merge dc44639904 dl/branch-cleanup later to maint).
-
- * A branch name used in a test has been clarified to match what is
-   going on.
-   (merge 08dc26061f pb/t4014-unslave later to maint).
-
- * An in-code comment in "git diff" has been updated.
-   (merge c592fd4c83 dl/diff-usage-comment-update later to maint).
-
- * The documentation and some tests have been adjusted for the recent
-   renaming of "pu" branch to "seen".
-   (merge 6dca5dbf93 js/pu-to-seen later to maint).
-
- * The code to push changes over "dumb" HTTP had a bad interaction
-   with the commit reachability code due to incorrect allocation of
-   object flag bits, which has been corrected.
-   (merge 64472d15e9 bc/http-push-flagsfix later to maint).
-
- * "git send-email --in-reply-to=<msg>" did not use the In-Reply-To:
-   header with the value given from the command line, and let it be
-   overridden by the value on In-Reply-To: header in the messages
-   being sent out (if exists).
-   (merge f9f60d7066 ra/send-email-in-reply-to-from-command-line-wins later to maint).
-
- * "git log -Lx,y:path --before=date" lost track of where the range
-   should be because it didn't take the changes made by the youngest
-   commits that are omitted from the output into account.
-
- * When "fetch.writeCommitGraph" configuration is set in a shallow
-   repository and a fetch moves the shallow boundary, we wrote out
-   broken commit-graph files that do not match the reality, which has
-   been corrected.
-
- * "git checkout" failed to catch an error from fstat() after updating
-   a path in the working tree.
-   (merge 35e6e212fd mt/entry-fstat-fallback-fix later to maint).
-
- * When an aliased command, whose output is piped to a pager by git,
-   gets killed by a signal, the pager got into a funny state, which
-   has been corrected (again).
-   (merge c0d73a59c9 ta/wait-on-aliased-commands-upon-signal later to maint).
-
- * The code to produce progress output from "git commit-graph --write"
-   had a few breakages, which have been fixed.
-
- * Other code cleanup, docfix, build fix, etc.
-   (merge 2c31a7aa44 jx/pkt-line-doc-count-fix later to maint).
-   (merge d63ae31962 cb/t5608-cleanup later to maint).
