e2d65c1ea8 filter-branch: stop suggesting to use grafts
The graft file is deprecated now, so let's use replace refs in the example

f60a7b763f worktree: teach "add" to check out existing branches
Currently 'git worktree add <path>' creates a new branch named after the
basename of the path by default.  If a branch with that name already
exists, the command refuses to do anything, unless the '--force' option
is given.

However we can do a little better than that, and check the branch out if
it is not checked out anywhere else.  This will help users who just want
to check an existing branch out into a new worktree, and save a few
keystrokes.

As the current behaviour is to simply 'die()' when a branch with the name
of the basename of the path already exists, there are no backwards
compatibility worries here.

We will still 'die()' if the branch is checked out in another worktree,
unless the --force flag is passed.

7543f6f444 rebase -i: introduce --rebase-merges=[no-]rebase-cousins
When running `git rebase --rebase-merges` non-interactively with an
ancestor of HEAD as <upstream> (or leaving the todo list unmodified),
we would ideally recreate the exact same commits as before the rebase.

However, if there are commits in the commit range <upstream>.. that do not
have <upstream> as direct ancestor (i.e. if `git log <upstream>..` would
show commits that are omitted by `git log --ancestry-path <upstream>..`),
this is currently not the case: we would turn them into commits that have
<upstream> as direct ancestor.

Let's illustrate that with a diagram:

        C
      /   \
A - B - E - F
  \   /
    D

Currently, after running `git rebase -i --rebase-merges B`, the new branch
structure would be (pay particular attention to the commit `D`):

       --- C' --
      /         \
A - B ------ E' - F'
      \    /
        D'

This is not really preserving the branch topology from before! The
reason is that the commit `D` does not have `B` as ancestor, and
therefore it gets rebased onto `B`.

This is unintuitive behavior. Even worse, when recreating branch
structure, most use cases would appear to want cousins *not* to be
rebased onto the new base commit. For example, Git for Windows (the
heaviest user of the Git garden shears, which served as the blueprint
for --rebase-merges) frequently merges branches from `next` early, and
these branches certainly do *not* want to be rebased. In the example
above, the desired outcome would look like this:

       --- C' --
      /         \
A - B ------ E' - F'
  \        /
   -- D' --

Let's introduce the term "cousins" for such commits ("D" in the
example), and let's not rebase them by default. For hypothetical
use cases where cousins *do* need to be rebased, `git rebase
--rebase=merges=rebase-cousins` needs to be used.

1131ec9818 pull: accept --rebase=merges to recreate the branch topology
Similar to the `preserve` mode simply passing the `--preserve-merges`
option to the `rebase` command, the `merges` mode simply passes the
`--rebase-merges` option.

This will allow users to conveniently rebase non-trivial commit
topologies when pulling new commits, without flattening them.

8f6aed71d2 rebase: introduce the --rebase-merges option
Once upon a time, this here developer thought: wouldn't it be nice if,
say, Git for Windows' patches on top of core Git could be represented as
a thicket of branches, and be rebased on top of core Git in order to
maintain a cherry-pick'able set of patch series?

The original attempt to answer this was: git rebase --preserve-merges.

However, that experiment was never intended as an interactive option,
and it only piggy-backed on git rebase --interactive because that
command's implementation looked already very, very familiar: it was
designed by the same person who designed --preserve-merges: yours truly.

Some time later, some other developer (I am looking at you, Andreas!
;-)) decided that it would be a good idea to allow --preserve-merges to
be combined with --interactive (with caveats!) and the Git maintainer
(well, the interim Git maintainer during Junio's absence, that is)
agreed, and that is when the glamor of the --preserve-merges design
started to fall apart rather quickly and unglamorously.

The reason? In --preserve-merges mode, the parents of a merge commit (or
for that matter, of *any* commit) were not stated explicitly, but were
*implied* by the commit name passed to the `pick` command.

This made it impossible, for example, to reorder commits. Not to mention
to move commits between branches or, deity forbid, to split topic branches
into two.

Alas, these shortcomings also prevented that mode (whose original
purpose was to serve Git for Windows' needs, with the additional hope
that it may be useful to others, too) from serving Git for Windows'
needs.

Five years later, when it became really untenable to have one unwieldy,
big hodge-podge patch series of partly related, partly unrelated patches
in Git for Windows that was rebased onto core Git's tags from time to
time (earning the undeserved wrath of the developer of the ill-fated
git-remote-hg series that first obsoleted Git for Windows' competing
approach, only to be abandoned without maintainer later) was really
untenable, the "Git garden shears" were born [*1*/*2*]: a script,
piggy-backing on top of the interactive rebase, that would first
determine the branch topology of the patches to be rebased, create a
pseudo todo list for further editing, transform the result into a real
todo list (making heavy use of the `exec` command to "implement" the
missing todo list commands) and finally recreate the patch series on
top of the new base commit.

That was in 2013. And it took about three weeks to come up with the
design and implement it as an out-of-tree script. Needless to say, the
implementation needed quite a few years to stabilize, all the while the
design itself proved itself sound.

With this patch, the goodness of the Git garden shears comes to `git
rebase -i` itself. Passing the `--rebase-merges` option will generate
a todo list that can be understood readily, and where it is obvious
how to reorder commits. New branches can be introduced by inserting
`label` commands and calling `merge <label>`. And once this mode will
have become stable and universally accepted, we can deprecate the design
mistake that was `--preserve-merges`.

25d5f52901 builtin/blame: highlight recently changed lines
Choose a different color for dates and imitate a 'temperature cool down'

Originally I had planned to have the temperature cool down dependent on
the age of the project or file for example, as that might scale better,
but that can be added on top of this commit, e.g. instead of giving a
date, you could imagine giving a percentage that would be the linearly
interpolated between now and the beginning of the file.

Similarly to the previous patch, this offers the command line option
'--color-by-age' to enable this mode and the config option
'color.blame.highlightrecent' to select colors. A later patch will offer
a config option to select the default mode.

cdc2d5f11f builtin/blame: dim uninteresting metadata lines
When using git-blame lots of lines contain redundant information, for
example in hunks that consist of multiple lines, the metadata (commit
name, author, date) are repeated. A reader may not be interested in those,
so offer an option to color the information that is repeated from the
previous line differently. Traditionally, we use CYAN for lines that
are less interesting than others (e.g. hunk header), so go with that.

The command line option '--color-lines' will trigger the coloring of
repeated lines, and the config option 'color.blame.colorLines' is
provided to select the color. Setting the config option doesn't imply
that repeated lines are colored. A later patch will introduce a config
to enable this mode by default.

2e85a0c8ab http-fetch: make -a standard behaviour
This is a follow-up to a6c786fce8 (Mark http-fetch without -a as
deprecated, 2011-08-23). For more than six years, we have been warning
when `-a` is not provided, and the documentation has been saying that
`-a` will become the default.

It is a bit unclear what "default" means here. There is no such thing as
`http-fetch --no-a`. But according to my searches, no-one has been
asking on the mailing list how they should silence the warning and
prepare for overriding the flipped default. So let's assume that
everybody is happy with `-a`. They should be, since not using it may
break the repo in such a way that Git itself is unable to fix it.

Always behave as if `-a` was given. Since `-a` implies `-c` (get commit
objects) and `-t` (get trees), all three options are now unnecessary.
Document all of these as historical artefacts that have no effect.

Leave no-op code for handling these options in http-fetch.c. The
options-handling is currently rather loose. If someone tightens it, we
will not want these ignored options to accidentally turn into hard
errors.

Since `-a` was the only safe and sane usage and we have been pushing
people towards it for a long time, refrain from warning when it is used
"unnecessarily" now. Similarly, do not add anything scary-looking to the
man-page about how it will be removed in the future. We can always do so
later. (It is not like we are in desperate need of freeing up
one-letter arguments.)

63e2a0f8e9 builtin/config: introduce color type specifier
As of this commit, the canonical way to retreive an ANSI-compatible
color escape sequence from a configuration file is with the
`--get-color` action.

This is to allow Git to "fall back" on a default value for the color
should the given section not exist in the specified configuration(s).

With the addition of `--default`, this is no longer needed since:

  $ git config --default red --type=color core.section

will be have exactly as:

  $ git config --get-color core.section red

For consistency, let's introduce `--type=color` and encourage its use
with `--default` together over `--get-color` alone.

eeaa24b990 builtin/config: introduce --default
For some use cases, callers of the `git-config(1)` builtin would like to
fallback to default values when the variable asked for does not exist.
In addition, users would like to use existing type specifiers to ensure
that values are parsed correctly when they do exist in the
configuration.

For example, to fetch a value without a type specifier and fallback to
`$fallback`, the following is required:

  $ git config core.foo || echo "$fallback"

This is fine for most values, but can be tricky for difficult-to-express
`$fallback`'s, like ANSI color codes.

This motivates `--get-color`, which is a one-off exception to the normal
type specifier rules wherein a user specifies both the configuration
variable and an optional fallback. Both are formatted according to their
type specifier, which eases the burden on the user to ensure that values
are correctly formatted.

This commit (and those following it in this series) aim to eventually
replace `--get-color` with a consistent alternative. By introducing
`--default`, we allow the `--get-color` action to be promoted to a
`--type=color` type specifier, retaining the "fallback" behavior via the
`--default` flag introduced in this commit.

For example, we aim to replace:

  $ git config --get-color variable [default] [...]

with:

  $ git config --default default --type=color variable [...]

Values filled by `--default` behave exactly as if they were present in
the affected configuration file; they will be parsed by type specifiers
without the knowledge that they are not themselves present in the
configuration.

Specifically, this means that the following will work:

  $ git config --int --default 1M does.not.exist
  1048576

In subsequent commits, we will offer `--type=color`, which (in
conjunction with `--default`) will be sufficient to replace
`--get-color`.

fb0dc3bac1 builtin/config.c: support --type=<type> as preferred alias for --<type>
`git config` has long allowed the ability for callers to provide a 'type
specifier', which instructs `git config` to (1) ensure that incoming
values can be interpreted as that type, and (2) that outgoing values are
canonicalized under that type.

In another series, we propose to extend this functionality with
`--type=color` and `--default` to replace `--get-color`.

However, we traditionally use `--color` to mean "colorize this output",
instead of "this value should be treated as a color".

Currently, `git config` does not support this kind of colorization, but
we should be careful to avoid squatting on this option too soon, so that
`git config` can support `--color` (in the traditional sense) in the
future, if that is desired.

In this patch, we support `--type=<int|bool|bool-or-int|...>` in
addition to `--int`, `--bool`, and etc. This allows the aforementioned
upcoming patch to support querying a color value with a default via
`--type=color --default=...`, without squandering `--color`.

We retain the historic behavior of complaining when multiple,
legacy-style `--<type>` flags are given, as well as extend this to
conflicting new-style `--type=<type>` flags. `--int --type=int` (and its
commutative pair) does not complain, but `--bool --type=int` (and its
commutative pair) does.

6955047ff4 git-[short]log.txt: unify quoted standalone --
In git-log.txt, we have an instance of \--, which is known to sometimes
render badly. This one is even worse than normal though, since ``\-- ''
(with or without that trailing space) appears to be entirely broken,
both in HTML and manpages, both with AsciiDoc (version 8.6.9) and
Asciidoctor (version 1.5.4).

Further down in git-log.txt we have a ``--'', which renders good. In
git-shortlog.txt, we use "\-- " (including the quotes and the space),
which happens to look fairly good. I failed to find any other similar
instances. So all in all, we quote a double-dash in three different
places and do it differently each time, with various degrees of success.

Switch all of these to `--`. This sets the double-dash in monospace and
matches what we usually do with example command line usages and options.
Note that we drop the trailing space as well, since `-- ` does not
render well. These should still be clear enough since just a few lines
above each instance, the space is clearly visible in a longer context.

Change all [\--] to [--]. This changes nothing for AsciiDoc version
8.6.9, but is an improvement for Asciidoctor version 1.5.4.

d228eea514 worktree: accept -f as short for --force for removal
Many commands support a "--force" option, frequently abbreviated as
"-f", however, "git worktree remove"'s hand-rolled OPT_BOOL forgets
to recognize the short form, despite git-worktree.txt documenting
"-f" as supported. Replace OPT_BOOL with OPT__FORCE, which provides
"-f" for free, and makes 'remove' consistent with 'add' option
parsing (which also specifies the PARSE_OPT_NOCOMPLETE flag).

a279b74c68 glossary: substitute "ancestor" for "direct ancestor" in 'push' description.
Even though "direct ancestor" is not defined in the glossary, the
common meaning of the term is simply "parent", parents being the only
direct ancestors, and the rest of ancestors being indirect ancestors.

As "parent" is obviously wrong in this place in the description, we
should simply say "ancestor", as everywhere else.

9806f5a7bf gc --auto: exclude base pack if not enough mem to "repack -ad"
pack-objects could be a big memory hog especially on large repos,
everybody knows that. The suggestion to stick a .keep file on the
giant base pack to avoid this problem is also known for a long time.

Recent patches add an option to do just this, but it has to be either
configured or activated manually. This patch lets `git gc --auto`
activate this mode automatically when it thinks `repack -ad` will use
a lot of memory and start affecting the system due to swapping or
flushing OS cache.

gc --auto decides to do this based on an estimation of pack-objects
memory usage, which is quite accurate at least for the heap part, and
whether that fits in half of system memory (the assumption here is for
desktop environment where there are many other applications running).

This mechanism only kicks in if gc.bigBasePackThreshold is not configured.
If it is, it is assumed that the user already knows what they want.

8fc6776247 gc: handle a corner case in gc.bigPackThreshold
This config allows us to keep <N> packs back if their size is larger
than a limit. But if this N >= gc.autoPackLimit, we may have a
problem. We are supposed to reduce the number of packs after a
threshold because it affects performance.

We could tell the user that they have incompatible gc.bigPackThreshold
and gc.autoPackLimit, but it's kinda hard when 'git gc --auto' runs in
background. Instead let's fall back to the next best stategy: try to
reduce the number of packs anyway, but keep the base pack out. This
reduces the number of packs to two and hopefully won't take up too
much resources to repack (the assumption still is the base pack takes
most resources to handle).

55dfe13df9 gc: add gc.bigPackThreshold config
The --keep-largest-pack option is not very convenient to use because
you need to tell gc to do this explicitly (and probably on just a few
large repos).

Add a config key that enables this mode when packs larger than a limit
are found. Note that there's a slight behavior difference compared to
--keep-largest-pack: all packs larger than the threshold are kept, not
just the largest one.

ae4e89e549 gc: add --keep-largest-pack option
This adds a new repack mode that combines everything into a secondary
pack, leaving the largest pack alone.

This could help reduce memory pressure. On linux-2.6.git, valgrind
massif reports 1.6GB heap in "pack all" case, and 535MB in "pack
all except the base pack" case. We save roughly 1GB memory by
excluding the base pack.

This should also lower I/O because we don't have to rewrite a giant
pack every time (e.g. for linux-2.6.git that's a 1.4GB pack file)..

PS. The use of string_list here seems overkill, but we'll need it in
the next patch...

ed7e5fc3a2 repack: add --keep-pack option
We allow to keep existing packs by having companion .keep files. This
is helpful when a pack is permanently kept. In the next patch, git-gc
just wants to keep a pack temporarily, for one pack-objects
run. git-gc can use --keep-pack for this use case.

A note about why the pack_keep field cannot be reused and
pack_keep_in_core has to be added. This is about the case when
--keep-pack is specified together with either --keep-unreachable or
--unpack-unreachable, but --honor-pack-keep is NOT specified.

In this case, we want to exclude objects from the packs specified on
command line, not from ones with .keep files. If only one bit flag is
used, we have to clear pack_keep on pack files with the .keep file.

But we can't make any assumption about unreachable objects in .keep
packs. If "pack_keep" field is false for .keep packs, we could
potentially pull lots of unreachable objects into the new pack, or
unpack them loose. The safer approach is ignore all packs with either
.keep file or --keep-pack.

e92d622536 convert: add round trip check based on 'core.checkRoundtripEncoding'
UTF supports lossless conversion round tripping and conversions between
UTF and other encodings are mostly round trip safe as Unicode aims to be
a superset of all other character encodings. However, certain encodings
(e.g. SHIFT-JIS) are known to have round trip issues [1].

Add 'core.checkRoundtripEncoding', which contains a comma separated
list of encodings, to define for what encodings Git should check the
conversion round trip if they are used in the 'working-tree-encoding'
attribute.

Set SHIFT-JIS as default value for 'core.checkRoundtripEncoding'.

107642fe26 convert: add 'working-tree-encoding' attribute
Git recognizes files encoded with ASCII or one of its supersets (e.g.
UTF-8 or ISO-8859-1) as text files. All other encodings are usually
interpreted as binary and consequently built-in Git text processing
tools (e.g. 'git diff') as well as most Git web front ends do not
visualize the content.

Add an attribute to tell Git what encoding the user has defined for a
given file. If the content is added to the index, then Git reencodes
the content to a canonical UTF-8 representation. On checkout Git will
reverse this operation.

* A list of metadata for the commits.
* A list of "large edges" to enable octopus merges.

The format automatically includes two parent positions for every
commit. This favors speed over space, since using only one position
per commit would cause an extra level of indirection for every merge
commit. (Octopus merges suffer from this indirection, but they are

c7620bd0f3 upload-pack: disable object filtering when disabled by config
When upload-pack gained partial clone support (v2.17.0-rc0~132^2~12,
2017-12-08), it was guarded by the uploadpack.allowFilter config item
to allow server operators to control when they start supporting it.

That config item didn't go far enough, though: it controls whether the
'filter' capability is advertised, but if a (custom) client ignores
the capability advertisement and passes a filter specification anyway,
the server would handle that despite allowFilter being false.

This is particularly significant if a security bug is discovered in
this new experimental partial clone code.  Installations without
uploadpack.allowFilter ought not to be affected since they don't
intend to support partial clone, but they would be swept up into being
vulnerable.

Simplify and limit the attack surface by making uploadpack.allowFilter
disable the feature, not just the advertisement of it.

--exec "make check" --signoff' which is useful when preparing a patch
series for publication and is more convenient than doing the signoff
with another --exec command.

This change also allows --root without --onto to work with --signoff
as well (--root with --onto was already supported).

0a790f09c6 git-stash.txt: remove extra square bracket
In 1ada5020b3 ("stash: use stash_push for no verb form", 2017-02-28),
when the pathspec argument was introduced in 'git stash', that was also
documented.  However I forgot to remove an extra square bracket after
the '--message' argument, even though the square bracket should have
been after the pathspec argument (where it was also added).

Remove the extra square bracket after the '--message' argument, to show
that the pathspec argument should be used with the 'push' verb.

While the pathspec argument can be used without the push verb, that's a
special case described later in the man page, and removing the first extra
square bracket instead of the second one makes the synopis easier to
understand.

5988eb631a doc hash-function-transition: clarify what SHAttered means
Attempt to clarify what the SHAttered attack means in practice for
Git. The previous version of the text made no mention whatsoever of
Git already having a mitigation for this specific attack, which the
SHAttered researchers claim will detect cryptanalytic collision
attacks.

I may have gotten some of the nuances wrong, but as far as I know this
new text accurately summarizes the current situation with SHA-1 in
git. I.e. git doesn't really use SHA-1 anymore, it uses
Hardened-SHA-1 (they just so happen to produce the same outputs
99.99999999999...% of the time).

Thus the previous text was incorrect in asserting that:

    [...]As a result [of SHAttered], SHA-1 cannot be considered
    cryptographically secure any more[...]

That's not the case. We have a mitigation against SHAttered, *however*
we consider it prudent to move to work towards a NewHash should future
vulnerabilities in either SHA-1 or Hardened-SHA-1 emerge.

rules for recursion are different.

In an ideal world, we would make them the same (if for

would create backwards compatibility issues. For some

3800135b89 worktree: delete dead code
This "link" was a feature in early iterations of multiple worktree
functionality for some reason it was dropped [1]. Since nobody creates
this "link", there's no need to check it.

This is mostly used to let the user moves a worktree manually [2]. If
you move a worktree within the same file system, this hard link count
lets us know the worktree is still there even if we don't know where it
is.

We support 'worktree move' now and don't need this anymore.

edc9caf7e2 transport-helper: introduce stateless-connect
Introduce the transport-helper capability 'stateless-connect'.  This
capability indicates that the transport-helper can be requested to run
the 'stateless-connect' command which should attempt to make a
stateless connection with a remote end.  Once established, the
connection can be used by the git client to communicate with
the remote end natively in a stateless-rpc manner as supported by
protocol v2.  This means that the client must send everything the server
needs in a single request as the client must not assume any
state-storing on the part of the server or transport.

If a stateless connection cannot be established then the remote-helper
will respond in the same manner as the 'connect' command indicating that
the client should fallback to using the dumb remote-helper commands.

A future patch will implement the 'stateless-connect' capability in our
http remote-helper (remote-curl) so that protocol v2 can be used using
the http transport.

Introduce git-serve, the base server for protocol version 2.

Protocol version 2 is intended to be a replacement for Git's current
wire protocol.  The intention is that it will be a simpler, less
wasteful protocol which can evolve over time.

Protocol version 2 improves upon version 1 by eliminating the initial
ref advertisement.  In its place a server will export a list of
capabilities and commands which it supports in a capability
advertisement.  A client can then request that a particular command be
executed by providing a number of capabilities and command specific
parameters.  At the completion of a command, a client can request that
another command be executed or can terminate the connection by sending a
flush packet.

a8210328f4 git-shortlog.txt: reorder usages
The first usage we give is the original one where, e.g., `git log` is
piped through `git shortlog`. The description that follows reads the
other way round, by first focusing on the general behavior, then ending
with the behavior when reading from stdin.

It is also a tiny bit odd that what is probably the most common usage
and the one a reader is probably looking for is not at the top of the
list. Of course, it is only a two-item list, so it is not _that_ hard to
find... The next commit will add the original usage to the usage string
in builtin/shortlog.c, and it feels more natural to do so below the
most common usage. To avoid being inconsistent, reorder these two
usages here first.

create a merge commit instead of fast-forwarding) when merging a

signed tags from their downstream contributors, but caused an
unnecessary merges when used by downstream contributors who
habitually "catch up" their topic branches with tagged releases
from the upstream.  Update "git merge" to default to --no-ff only

d11c943c78 send-email: support separate Reply-To address
In some projects contributions from groups are only accepted from a
common group email address. But every individual may want to receive
replies to her own personal address. That's what we have 'Reply-To'
headers for in SMTP. So introduce an optional '--reply-to' command
line option.

This patch re-uses the $reply_to variable. This could break
out-of-tree patches!

0aa7a78099 smart-http: document flush after "# service" line
The http-protocol.txt spec fails to mention that a flush packet
comes in the smart server response after sending the "service"
header.

Technically the client code is actually ready to receive an
arbitrary number of headers here, but since we haven't
introduced any other headers in the past decade (and the
client would just throw them away), let's not mention it in
the spec.

This fixes both BNF and the example. While we're fixing the
latter, let's also add the missing flush after the ref list.

1dbf0c0ad6 userdiff: add built-in pattern for golang
This adds xfuncname and word_regex patterns for golang, a quite
popular programming language. It also includes test cases for the
xfuncname regex (t4018) and updated documentation.

The xfuncname regex finds functions, structs and interfaces.  Although
the Go language prohibits the opening brace from being on its own
line, the regex does not makes it mandatory, to be able to match
`func` statements like this:

    func foo(bar int,
    	baz int) {
    }

This is covered by the test case t4018/golang-long-func.

The word_regex pattern finds identifiers, integers, floats, complex
numbers and operators, according to the go specification.

ddf88fa616 diff: add --compact-summary
Certain information is currently shown with --summary, but when used
in combination with --stat it's a bit hard to read since info of the
same file is in two places (--stat and --summary).

On top of that, commits that add or remove files double the number of
display lines, which could be a lot if you add or remove a lot of
files.

--compact-summary embeds most of --summary back in --stat in the
little space between the file name part and the graph line, e.g. with
commit 0433d533f1:

   Documentation/merge-config.txt         |  4 +
   builtin/merge.c                        |  2 +
   ...-pull-verify-signatures.sh (new +x) | 81 ++++++++++++++
   t/t7612-merge-verify-signatures.sh     | 45 ++++++++
   4 files changed, 132 insertions(+)

It helps both condensing information and saving some text
space. What's new in diffstat is:

- A new 0644 file is shown as (new)
- A new 0755 file is shown as (new +x)
- A new symlink is shown as (new +l)
- A deleted file is shown as (gone)
- A mode change adding executable bit is shown as (mode +x)
- A mode change removing it is shown as (mode -x)

Note that --compact-summary does not contain all the information
--summary provides. Rewrite percentage is not shown but it could be
added later, like R50% or C20%.

32888b8fd5 config: respect pager.config in list/get-mode only
Similar to de121ffe5 (tag: respect `pager.tag` in list-mode only,
2017-08-02), use the DELAY_PAGER_CONFIG-mechanism to only respect
`pager.config` when we are listing or "get"ing config.

We have several getters and some are guaranteed to give at most one line
of output. Paging all getters including those could be convenient from a
documentation point-of-view. The downside would be that a misconfigured
or not so modern pager might wait for user interaction before
terminating. Let's instead respect the config for precisely those
getters which may produce more than one line of output.

`--get-urlmatch` may or may not produce multiple lines of output,
depending on the exact usage. Let's not try to recognize the two modes,
but instead make `--get-urlmatch` always respect the config. Analyzing
the detailed usage might be trivial enough here, but could establish a
precedent that we will never be able to enforce throughout the codebase
and that will just open a can of worms.

This fixes the failing test added in the previous commit. Also adapt the
test for whether `git config foo.bar bar` and `git config --get foo.bar`
respects `pager.config`.

d023df1ee6 git-worktree.txt: fix indentation of example and text of 'add' command
When 4e85333197 (worktree: make add <path> <branch> dwim, 2017-11-26)
added an example command in a literal code block, it neglected to
insert a mandatory "+" line before the block. This omission resulted
in both the literal code block and the (existing) paragraph following
the block to be outdented, even though they should be indented under
the 'add' sub-command along with the rest of the text pertaining to
that command. Furthermore, the mandatory "+" line separating the code
block from the following text got rendered as a leading character on
the line ("+ If <commit-ish>...") rather than being treated as a
formatting directive.

Fix these problems by adding the missing "+" line before the example
code block.

adcc94a0aa merge: allow fast-forward when merging a tracked tag
Long time ago at fab47d05 ("merge: force edit and no-ff mode when
merging a tag object", 2011-11-07), "git merge" was made to always
create a merge commit when merging a tag, even when the side branch
being merged is a descendant of the current branch.

This default is good for merges made by upstream maintainers to
integrate work signed by downstream contributors, but will leave
pointless no-ff merges when downstream contributors pull a newer
release tag to make their long-running topic branches catch up with
the upstream.  When there is no local work left on the topic, such a
merge should simply fast-forward to the commit pointed at by the
release tag.

Update the default (again) for "git merge" that merges a tag object
to (1) --no-ff (i.e. create a merge commit even when side branch
fast forwards) if the tag being merged is not at its expected place
in refs/tags/ hierarchy and (2) --ff (i.e. allow fast-forward update
when able) otherwise.

e4e5da2796 Documentation/git-status: clarify status table for porcelain mode
It is possible to have the output ' A' from 'git status --porcelain'
by adding a file using the '--intend-to-add' flag.  Make this clear by
adding the pattern in the table of the documentation.

However the mode 'DM' (deleted in the index, modified in the working tree)
is not possible in the non-merge case in which the file only shows
as 'D ' (and adding it back to the worktree would show an additional line
of an '??' untracked file). It is also not possible in the merge case as
then the mode involves a 'U' on one side of the merge.
Remove that pattern.

In preparation for implementing narrow/partial clone, the machinery
for checking object connectivity used by gc and fsck has been
taught that a missing object is OK when it is referenced by a
packfile specially marked as coming from trusted repository that
promises to make them available on-demand and lazily.

fbd7a23237 rebase: introduce and use pseudo-ref REBASE_HEAD
The new command `git rebase --show-current-patch` is useful for seeing
the commit related to the current rebase state. Some however may find
the "git show" command behind it too limiting. You may want to
increase context lines, do a diff that ignores whitespaces...

For these advanced use cases, the user can execute any command they
want with the new pseudo ref REBASE_HEAD.

This also helps show where the stopped commit is from, which is hard
to see from the previous patch which implements --show-current-patch.

cc73385cf6 worktree remove: new command
This command allows to delete a worktree. Like 'move' you cannot
remove the main worktree, or one with submodules inside [1].

For deleting $GIT_WORK_TREE, Untracked files or any staged entries are
considered precious and therefore prevent removal by default. Ignored
files are not precious.

When it comes to deleting $GIT_DIR, there's no "clean" check because
there should not be any valuable data in there, except:

- HEAD reflog. There is nothing we can do about this until somebody
  steps up and implements the ref graveyard.

- Detached HEAD. Technically it can still be recovered. Although it
  may be nice to warn about orphan commits like 'git checkout' does.

[1] We do 'git status' with --ignore-submodules=all for safety
    anyway. But this needs a closer look by submodule people before we
    can allow deletion. For example, if a submodule is totally clean,
    but its repo not absorbed to the main .git dir, then deleting
    worktree also deletes the valuable .submodule repo too.

9f792bb472 worktree move: new command
This command allows to relocate linked worktrees. Main worktree cannot
(yet) be moved.

There are two options to move the main worktree, but both have
complications, so it's not implemented yet. Anyway the options are:

- convert the main worktree to a linked one and move it away, leave
  the git repository where it is. The repo essentially becomes bare
  after this move.

- move the repository with the main worktree. The tricky part is make
  sure all file descriptors to the repository are closed, or it may
  fail on Windows.

Since this is very likely something others will encounter in the

document both that it exists, and how to "fix" it with a one-off

As noted in that commit, even though this bug gets the untracked cache
into a bad state, we have not yet found a case where this is user
visible, and thus it makes sense for these docs to focus on the

97716d217c fetch: add a --prune-tags option and fetch.pruneTags config
Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:

    git fetch -p -P
    git fetch --prune --prune-tags
    git fetch -p -P origin
    git fetch --prune --prune-tags origin

Or simply:

    git config fetch.prune true &&
    git config fetch.pruneTags true &&
    git fetch

Instead of the much more verbose:

    git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'

Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.

At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.

Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:

    git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"

Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.

Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.

It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.

Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.

The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.

All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().

It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.

d0e07472fa git remote doc: correct dangerous lies about what prune does
The "git remote prune <name>" command uses the same machinery as "git
fetch <name> --prune", and shares all the same caveats, but its
documentation has suggested that it'll just "delete stale
remote-tracking branches under <name>".

This isn't true, and hasn't been true since at least v1.8.5.6 (the
oldest version I could be bothered to test).

E.g. if "refs/tags/*:refs/tags/*" is explicitly set in the refspec of
the remote, it'll delete all local tags <name> doesn't know about.

Instead, briefly give the reader just enough of a hint that this
option might constitute a shotgun aimed at their foot, and point them
to the new PRUNING section in the git-fetch documentation which
explains all the nuances of what this facility does.

config" (CACi5S_39wNrbfjLfn0xhCY+uewtFN2YmnAcRc86z6pjUTjWPHQ@mail.gmail.com)

89a9f2c862 CodingGuidelines: mention "static" and "extern"
It perhaps goes without saying that file-local stuff should
be marked static, but it does not hurt to remind people.

Less obvious is that we are settling on "do not include
extern in function declarations". It is already the default
unless the function was previously declared static (but if
you are following a static declaration with an unmarked one,
you should think about why you are declaring the thing
twice). And so it just becomes an extra noise-word in our
header files.

We used to give the opposite advice, so there are quite a
few "extern" markers in early Git code. But this at least
makes a concrete suggestion that we can follow going
forward.

a6c612b528 rebase: add --allow-empty-message option
This option allows commits with empty commit messages to be rebased,
matching the same option in git-commit and git-cherry-pick. While empty
log messages are frowned upon, sometimes one finds them in older
repositories (e.g. translated from another VCS [0]), or have other
reasons for desiring them. The option is available in git-commit and
git-cherry-pick, so it is natural to make other git tools play nicely
with them. Adding this as an option allows the default to be "give the
user a chance to fix", while not interrupting the user's workflow
otherwise [1].

0c591cacba daemon: add --log-destination=(stderr|syslog|none)
This new option can be used to override the implicit --syslog of
--inetd, or to disable all logging. (While --detach also implies
--syslog, --log-destination=stderr with --detach is useless since
--detach disassociates the process from the original stderr.) --syslog
is retained as an alias for --log-destination=syslog.

--log-destination always overrides implicit --syslog regardless of
option order. This is different than the “last one wins” logic that
applies to some implicit options elsewhere in Git, but should hopefully
be less confusing. (I also don’t know if *all* implicit options in Git
follow “last one wins”.)

The combination of --inetd with --log-destination=stderr is useful, for
instance, when running `git daemon` as an instanced systemd service
(with associated socket unit). In this case, log messages sent via
syslog are received by the journal daemon, but run the risk of being
processed at a time when the `git daemon` process has already exited
(especially if the process was very short-lived, e.g. due to client
error), so that the journal daemon can no longer read its cgroup and
attach the message to the correct systemd unit (see systemd/systemd#2913
[1]). Logging to stderr instead can solve this problem, because systemd
can connect stderr directly to the journal daemon, which then already
knows which unit is associated with this stream.

9bd2ce5432 cat-file doc: document that -e will return some output
The -e option added in 7950571ad7 ("A few more options for
git-cat-file", 2005-12-03) has always errored out with message on
stderr saying that the provided object is malformed, like this:

    $ git cat-file -e malformed; echo $?
    fatal: Not a valid object name malformed
    128

A reader of this documentation may be misled into thinking that

    if ! git cat-file -e "$object" [...]

as opposed to:

    if ! git cat-file -e "$object" 2>/dev/null [...]

is sufficient to implement a truly silent test that checks whether
some arbitrary $object string was both valid, and pointed to an
object that exists.

15af58c1ad diffcore: add a pickaxe option to find a specific blob
Sometimes users are given a hash of an object and they want to
identify it further (ex.: Use verify-pack to find the largest blobs,
but what are these? or [1])

One might be tempted to extend git-describe to also work with blobs,
such that `git describe <blob-id>` gives a description as
'<commit-ish>:<path>'.  This was implemented at [2]; as seen by the sheer
number of responses (>110), it turns out this is tricky to get right.
The hard part to get right is picking the correct 'commit-ish' as that
could be the commit that (re-)introduced the blob or the blob that
removed the blob; the blob could exist in different branches.

Junio hinted at a different approach of solving this problem, which this
patch implements. Teach the diff machinery another flag for restricting
the information to what is shown. For example:

    $ ./git log --oneline --find-object=v2.0.0:Makefile
    b2feb64309 Revert the whole "ask curl-config" topic for now
    47fbfded53 i18n: only extract comments marked with "TRANSLATORS:"

we observe that the Makefile as shipped with 2.0 was appeared in
v1.9.2-471-g47fbfded53 and in v2.0.0-rc1-5-gb2feb6430b.  The
reason why these commits both occur prior to v2.0.0 are evil
merges that are not found using this new mechanism.

46af107bde docs/diff-options: clarify scope of diff-filter types
The same document for "--diff-filter" is included by many
programs in the diff family. Because it mentions all
possible types (added, removed, etc), this may imply to the
reader that all types can be generated by a particular
command. But this isn't necessarily the case; "diff-files"
cannot generally produce an "Added" entry, since the diff is
limited to what is already in the index.

Let's make it clear that the list here is the full one, and
does not imply anything about what a particular invocation
may produce.

Note that conditionally including items (e.g., omitting
"Added" in the git-diff-files manpage) isn't the right
solution here for two reasons:

  - The problem isn't diff-files, but doing an index to
    working tree diff. "git diff" can do the same diff, but
    also has other modes where "Added" does show up.

  - The direction of the diff matters. Doing "diff-files -R"
    can get you Added entries (but not Deleted ones).

So it's best just to explain that the set of available types
depends on the specific diff invocation.

c9e3d472f9 doc/SubmittingPatches: improve text formatting
049e64aa50 ("Documentation: convert SubmittingPatches to AsciiDoc",
2017-11-12) changed the `git blame` and `git shortlog` examples given in
the section on sending your patches.

In order to italicize the `$path` argument the commands are enclosed in
plus characters as opposed to backticks.  The difference between the
quoting methods is that backtick enclosed text is not subject to further
expansion.  This formatting makes reading SubmittingPatches in a git
clone a little more difficult.  In addition to the underscores around
`$path` the `--` chars in `git shortlog --no-merges` must be replaced
with `{litdd}`.

Use backticks to quote these commands.  The italicized `$path` is lost
from the html version but the commands can be read (and copied) more
easily by users reading the text version.  These readers are more likely
to use the commands while submitting patches.  Make it easier for them.

176ea74793 wt-status.c: handle worktree renames
Before 425a28e0a4 (diff-lib: allow ita entries treated as "not yet exist
in index" - 2016-10-24) there are never "new files" in the index, which
essentially disables rename detection because we only detect renames
when a new file appears in a diff pair.

After that commit, an i-t-a entry can appear as a new file in "git
diff-files". But the diff callback function in wt-status.c does not
handle this case and produces incorrect status output.

PS. The reader may notice that this patch adds a new xstrdup() but not
a free(). Yes we leak memory (the same for head_path). But wt_status
so far has been short lived, this leak should not matter in
practice.

8cf422dbf1 git-p4: update multiple shelved change lists
--update-shelve can now be specified multiple times on the
command-line, to update multiple shelved changelists in a single
submit.

This then means that a git patch series can be mirrored to a
sequence of shelved changelists, and (relatively easily) kept in
sync as changes are made in git.

Note that Perforce does not really support overlapping shelved
changelists where one change touches the files modified by
another. Trying to do this will result in merge conflicts.

30884c9afc commit: add support for --fixup <commit> -m"<extra message>"
Add support for supplying the -m option with --fixup. Doing so has
errored out ever since --fixup was introduced. Before this, the only
way to amend the fixup message while committing was to use --edit and
amend it in the editor.

The use-case for this feature is one of:

 * Leaving a quick note to self when creating a --fixup commit when
   it's not self-evident why the commit should be squashed without a
   note into another one.

 * (Ab)using the --fixup feature to "fix up" commits that have already
   been pushed to a branch that doesn't allow non-fast-forwards,
   i.e. just noting "this should have been part of that other commit",
   and if the history ever got rewritten in the future the two should
   be combined.

   In such a case you might want to leave a small message,
   e.g. "forgot this part, which broke XYZ".

With this, --fixup <commit> -m"More" -m"Details" will result in a
commit message like:

    !fixup <subject of <commit>>

    More

    Details

The reason the test being added here seems to squash "More" at the end
of the subject line of the commit being fixed up is because the test
code is using "%s%b" so the body immediately follows the subject, it's
not a bug in this code, and other tests t7500-commit.sh do the same
thing.

When the --fixup option was initially added the "Option -m cannot be
combined" error was expanded from -c, -C and -F to also include
--fixup[1]

Those options could also support combining with -m, but given what
they do I can't think of a good use-case for doing that, so I have not
made the more invasive change of splitting up the logic in commit.c to
first act on those, and then on -m options.

1feb061701 config.txt: document behavior of backslashes in subsections
Unrecognized escape sequences are invalid in values:

  $ git config -f - --list <<EOF
  [foo]
    bar = "\t\\\y\"\u"
  EOF
  fatal: bad config line 2 in standard input

But in subsection names, the backslash is simply dropped if the
following character does not produce a recognized escape sequence:

  $ git config -f - --list <<EOF
  [foo "\t\\\y\"\u"]
    bar = baz
  EOF
  foo.t\y"u.bar=baz

Although it would be nice for subsection names and values to have
consistent behavior, changing the behavior for subsection names is a
nonstarter since it would cause existing, valid config files to
suddenly be interpreted differently.
