There are occasions when you decide to abort an in-progress rebase and
move on to do something else but you forget to do "git rebase --abort"
first. Or the rebase has been in progress for so long you forgot about
it. By the time you realize that (e.g. by starting another rebase)
it's already too late to retrace your steps. The solution is normally
rm -r .git/<some rebase dir>
and continue with your life. But there could be two different
directories for <some rebase dir> (and it obviously requires some
knowledge of how rebase works), and the ".git" part could be much
longer if you are not at top-dir, or in a linked worktree. And
"rm -r" is very dangerous to do in .git, a mistake in there could
destroy object database or other important data.
Provide "git rebase --quit" for this use case, mimicking a precedent
that is "git cherry-pick --quit".

By adding the word "just", which might have been accidentally omitted.
Adding the word "just" makes it clear that the point is to *not* do an
octopus merge simply because you *can* do it. In other words, you
should have a reason for doing it beyond simply having two (seemingly)
independent commits that you need to merge into another branch, since
it's not always the best approach.
The previous sentence made it look more like it was trying to say that
you shouldn't do an octopus merge *because* you can do an octopus merge.
Although this interpretation doesn't make sense and the rest of the
paragraph makes the intended meaning clear, this adjustment should make
the intent of the sentence more immediately clear to the reader.

We instruct curl to always follow HTTP redirects. This is
convenient, but it creates opportunities for malicious
servers to create confusing situations. For instance,
imagine Alice is a git user with access to a private
repository on Bob's server. Mallory runs her own server and
wants to access objects from Bob's repository.
Mallory may try a few tricks that involve asking Alice to
clone from her, build on top, and then push the result:
1. Mallory may simply redirect all fetch requests to Bob's
server. Git will transparently follow those redirects
and fetch Bob's history, which Alice may believe she
got from Mallory. The subsequent push seems like it is
just feeding Mallory back her own objects, but is
actually leaking Bob's objects. There is nothing in
git's output to indicate that Bob's repository was
involved at all.
The downside (for Mallory) of this attack is that Alice
will have received Bob's entire repository, and is
likely to notice that when building on top of it.
2. If Mallory happens to know the sha1 of some object X in
Bob's repository, she can instead build her own history
that references that object. She then runs a dumb http
server, and Alice's client will fetch each object
individually. When it asks for X, Mallory redirects her
to Bob's server. The end result is that Alice obtains
objects from Bob, but they may be buried deep in
history. Alice is less likely to notice.
Both of these attacks are fairly hard to pull off. There's a
social component in getting Mallory to convince Alice to
work with her. Alice may be prompted for credentials in
accessing Bob's repository (but not always, if she is using
a credential helper that caches). Attack (1) requires a
certain amount of obliviousness on Alice's part while making
a new commit. Attack (2) requires that Mallory knows a sha1
in Bob's repository, that Bob's server supports dumb http,
and that the object in question is loose on Bob's server.
But we can probably make things a bit more obvious without
any loss of functionality. This patch does two things to
that end.
First, when we encounter a whole-repo redirect during the
initial ref discovery, we now inform the user on stderr,
making attack (1) much more obvious.
Second, the decision to follow redirects is now
configurable. The truly paranoid can set the new
http.followRedirects to false to avoid any redirection
entirely. But for a more practical default, we will disallow
redirects only after the initial ref discovery. This is
enough to thwart attacks similar to (2), while still
allowing the common use of redirects at the repository
level. Since c93c92f30 (http: update base URLs when we see
redirects, 2013-09-28) we re-root all further requests from
the redirect destination, which should generally mean that
no further redirection is necessary.
As an escape hatch, in case there really is a server that
needs to redirect individual requests, the user can set
http.followRedirects to "true" (and this can be done on a
per-server basis via http.*.followRedirects config).

This options makes sorting ignore case, which is great when you have
branches named bug-12-do-something, Bug-12-do-some-more and
BUG-12-do-what and want to group them together. Sorting externally may
not be an option because we lose coloring and column layout from
git-branch and git-tag.
The same could be said for filtering, but it's probably less important
because you can always go with the ugly pattern [bB][uU][gG]-* if you're
desperate.
You can't have case-sensitive filtering and case-insensitive sorting (or
the other way around) with this though. For branch and tag, that should
be no problem. for-each-ref, as a plumbing, might want finer control.
But we can always add --{filter,sort}-ignore-case when there is a need

Git's clean/smudge mechanism invokes an external filter process for
every single blob that is affected by a filter. If Git filters a lot of
blobs then the startup time of the external filter processes can become
a significant part of the overall Git execution time.
In a preliminary performance test this developer used a clean/smudge
filter written in golang to filter 12,000 files. This process took 364s
with the existing filter mechanism and 5s with the new mechanism. See
details here: https://github.com/github/git-lfs/pull/1382
This patch adds the `filter.<driver>.process` string option which, if
used, keeps the external filter process running and processes all blobs
with the packet format (pkt-line) based protocol over standard input and
standard output. The full protocol is explained in detail in
`Documentation/gitattributes.txt`.
A few key decisions:
* The long running filter process is referred to as filter protocol
version 2 because the existing single shot filter invocation is
considered version 1.
* Git sends a welcome message and expects a response right after the
external filter process has started. This ensures that Git will not
hang if a version 1 filter is incorrectly used with the
filter.<driver>.process option for version 2 filters. In addition,
Git can detect this kind of error and warn the user.
* The status of a filter operation (e.g. "success" or "error) is set
before the actual response and (if necessary!) re-set after the
response. The advantage of this two step status response is that if
the filter detects an error early, then the filter can communicate
this and Git does not even need to create structures to read the
response.
* All status responses are pkt-line lists terminated with a flush
packet. This allows us to send other status fields with the same
protocol in the future.

For each signature only one of the codes GOODSIG, BADSIG,
EXPSIG, EXPKEYSIG, REVKEYSIG or ERRSIG will be emitted.
gpg1 ("classic") behaves the same (although doc/DETAILS differs).
Currently, we parse gpg's status output for GOODSIG, BADSIG and
trust information and translate that into status codes G, B, U, N
for the %G? format specifier.
git-verify-* returns success in the GOODSIG case only. This is
somewhat in disagreement with gpg, which considers the first 5 of
the 6 above as VALIDSIG, but we err on the very safe side.
Introduce additional status codes E, X, Y, R for ERRSIG, EXPSIG,
EXPKEYSIG, and REVKEYSIG so that a user of %G? gets more information
about the absence of a 'G' on first glance.

Unlike the url variable a user cannot override the the path variable,
as it is part of the content together with the gitlink at the given
path. To avoid confusion do not mention the .path variable in the config
section and rely on the documentation provided in gitmodules[5].
Enhance the description of submodule.<name>.url and mention its two use
cases separately.

It is a common mistake to say "git blame --reverse OLD path",
expecting that the command line is dwimmed as if asking how lines
in path in an old revision OLD have survived up to the current
commit.

The existing "git fetch --depth=<n>" option was hard to use
correctly when making the history of an existing shallow clone
deeper. A new option, "--deepen=<n>", has been added to make this
easier to use. "git clone" also learned "--shallow-since=<date>"
and "--shallow-exclude=<tag>" options to make it easier to specify
"I am interested only in the recent N months worth of history" and
"Give me only the history since that version".

There's no way to get the list of alternates that git
computes internally; our tests only infer it based on which
objects are available. In addition to testing, knowing this
list may be helpful for somebody debugging their alternates
setup.
Let's add it to the "count-objects -v" output. We could give
it a separate flag, but there's not really any need.
"count-objects -v" is already a debugging catch-all for the
object database, its output is easily extensible to new data
items, and printing the alternates is not expensive (we
already had to find them to count the objects).

Pathspecs can be a bit tricky when trying to apply them to submodules.
The main challenge is that the pathspecs will be with respect to the
superproject and not with respect to paths in the submodule. The
approach this patch takes is to pass in the identical pathspec from the
superproject to the submodule in addition to the submodule-prefix, which
is the path from the root of the superproject to the submodule, and then
we can compare an entry in the submodule prepended with the
submodule-prefix to the pathspec in order to determine if there is a
match.
This patch also permits the pathspec logic to perform a prefix match against
submodules since a pathspec could refer to a file inside of a submodule.
Due to limitations in the wildmatch logic, a prefix match is only done
literally. If any wildcard character is encountered we'll simply punt
and produce a false positive match. More accurate matching will be done
once inside the submodule. This is due to the superproject not knowing
what files could exist in the submodule.

Allow ls-files to recognize submodules in order to retrieve a list of
files from a repository's submodules. This is done by forking off a
process to recursively call ls-files on all submodules. Use top-level
--super-prefix option to pass a path to the submodule which it can
use to prepend to output or pathspec matching logic.

Add a super-prefix environment variable 'GIT_INTERNAL_SUPER_PREFIX'
which can be used to specify a path from above a repository down to its
root. When such a super-prefix is specified, the paths reported by Git
are prefixed with it to make them relative to that directory "above".
The paths given by the user on the command line
(e.g. "git subcmd --output-file=path/to/a/file" and pathspecs) are taken
relative to the directory "above" to match.
The immediate use of this option is by commands which have a
--recurse-submodule option in order to give context to submodules about
how they were invoked. This option is currently only allowed for
builtins which support a super-prefix.

"git log rev^..rev" is an often-used revision range specification
to show what was done on a side branch merged at rev. This has
gained a short-hand "rev^-1". In general "rev^-$n" is the same as
"^rev^$n rev", i.e. what has happened on other branches while the
history leading to nth parent was looking the other way.

When given an abbreviated object name that is not (or more
realistically, "no longer") unique, we gave a fatal error
"ambiguous argument". This error is now accompanied by hints that
lists the objects that begins with the given prefix. During the
course of development of this new feature, numerous minor bugs were
uncovered and corrected, the most notable one of which is that we
gave "short SHA1 xxxx is ambiguous." twice without good reason.

How pathspec is used, with and without --interactive/--patch, is
different. But this is not clear from the document. These changes hint
the user to keep reading (to option #5) instead of stopping at #2 and
assuming --patch/--interactive behaves the same way.
And since all the options listed here always mention how the index is
involved (or not) in the final commit, add that bit for #5 as well. This
"on top of the index" is implied when you head over git-add(1), but if
you just go straight to the "Interactive mode" and not read what git-add
is for, you may miss it.
