055930bc89 branch: deprecate "-l" option
The "-l" option is short for "--create-reflog". This has
caused much confusion over the years. Most people expect it
to work as "--list", because that would match the other
"mode" options like -d/--delete and -m/--move, as well as
the similar -l/--list option of git-tag.

Adding to the confusion, using "-l" _appears_ to work as
"--list" in some cases:

  $ git branch -l
  * master

because the branch command defaults to listing (so even
trying to specify --list in the command above is redundant).
But that may bite the user later when they add a pattern,
like:

  $ git branch -l foo

which does not return an empty list, but in fact creates a
new branch (with a reflog, naturally) called "foo".

It's also probably quite uncommon for people to actually use
"-l" to create a reflog. Since 0bee591869 (Enable reflogs by
default in any repository with a working directory.,
2006-12-14), this is the default in non-bare repositories.
So it's rather unfortunate that the feature squats on the
short-and-sweet "-l" (which was only added in 3a4b3f269c
(Create/delete branch ref logs., 2006-05-19), meaning there
were only 7 months where it was actually useful).

Let's deprecate "-l" in hopes of eventually re-purposing it
to "--list".

Note that we issue the warning only when we're not in list
mode. This means that people for whom it works as a happy
accident, namely:

  $ git branch -l
  master

won't see the warning at all. And when we eventually switch
to it meaning "--list", that will just continue to work.

We do the issue the warning for these important cases:

  - when we are actually creating a branch, in case the user
    really did mean it as "--create-reflog"

  - when we are in some _other_ mode, like deletion. There
    the "-l" is a noop for now, but it will eventually
    conflict with any other mode request, and the user
    should be told that this is changing.

a449f27ffa builtin/grep.c: add '--column' option to 'git-grep(1)'
Teach 'git-grep(1)' a new option, '--column', to show the column
number of the first match on a non-context line. This makes it possible
to teach 'contrib/git-jump/git-jump' how to seek to the first matching

b2453d3449 RelNotes 2.18: clarify where directory rename detection applies
Mention that this feature works with some commands (merge and cherry-pick,
implying that it also works with commands that build on these like rebase
-m and rebase -i).  Explicitly mentioning two commands hopefully implies
that it may not always work with other commands (am, and rebase without
flags that imply either -m or -i).

Also, since the directory rename detection from this cycle was
specifically added in merge-recursive and not diffcore-rename, remove the
'in "diff" family" phrase from the note.  (Folks have requested in the
past that `git diff` detect directory renames and somehow simplify its
output, so it may be helpful to avoid implying that diff has any new
capability here.)

f55b87c1c7 git-p4: add options --commit and --disable-rebase
On a daily work with multiple local git branches, the usual way to
submit only a specified commit was to cherry-pick the commit on
master then run git-p4 submit.  It can be very annoying to switch
between local branches and master, only to submit one commit.  The
proposed new way is to select directly the commit you want to
submit.

Add option --commit to command 'git-p4 submit' in order to submit
only specified commit(s) in p4.

On a daily work developping software with big compilation time, one
may not want to rebase on his local git tree, in order to avoid long
recompilation.

Add option --disable-rebase to command 'git-p4 submit' in order to
disable rebase after submission.

8d7b558bae checkout & worktree: introduce checkout.defaultRemote
Introduce a checkout.defaultRemote setting which can be used to
designate a remote to prefer (via checkout.defaultRemote=origin) when
running e.g. "git checkout master" to mean origin/master, even though
there's other remotes that have the "master" branch.

I want this because it's very handy to use this workflow to checkout a
repository and create a topic branch, then get back to a "master" as
retrieved from upstream:

    (
        cd /tmp &&
        rm -rf tbdiff &&
        git clone git@github.com:trast/tbdiff.git &&
        cd tbdiff &&
        git branch -m topic &&
        git checkout master
    )

That will output:

    Branch 'master' set up to track remote branch 'master' from 'origin'.
    Switched to a new branch 'master'

But as soon as a new remote is added (e.g. just to inspect something
from someone else) the DWIMery goes away:

    (
        cd /tmp &&
        rm -rf tbdiff &&
        git clone git@github.com:trast/tbdiff.git &&
        cd tbdiff &&
        git branch -m topic &&
        git remote add avar git@github.com:avar/tbdiff.git &&
        git fetch avar &&
        git checkout master
    )

Will output (without the advice output added earlier in this series):

    error: pathspec 'master' did not match any file(s) known to git.

The new checkout.defaultRemote config allows me to say that whenever
that ambiguity comes up I'd like to prefer "origin", and it'll still
work as though the only remote I had was "origin".

Also adjust the advice.checkoutAmbiguousRemoteBranchName message to
mention this new config setting to the user, the full output on my
git.git is now (the last paragraph is new):

    $ ./git --exec-path=$PWD checkout master
    error: pathspec 'master' did not match any file(s) known to git.
    hint: 'master' matched more than one remote tracking branch.
    hint: We found 26 remotes with a reference that matched. So we fell back
    hint: on trying to resolve the argument as a path, but failed there too!
    hint:
    hint: If you meant to check out a remote tracking branch on, e.g. 'origin',
    hint: you can do so by fully qualifying the name with the --track option:
    hint:
    hint:     git checkout --track origin/<name>
    hint:
    hint: If you'd like to always have checkouts of an ambiguous <name> prefer
    hint: one remote, e.g. the 'origin' remote, consider setting
    hint: checkout.defaultRemote=origin in your config.

I considered splitting this into checkout.defaultRemote and
worktree.defaultRemote, but it's probably less confusing to break our
own rules that anything shared between config should live in core.*
than have two config settings, and I couldn't come up with a short
name under core.* that made sense (core.defaultRemoteForCheckout?).

See also 70c9ac2f19 ("DWIM "git checkout frotz" to "git checkout -b
frotz origin/frotz"", 2009-10-18) which introduced this DWIM feature
to begin with, and 4e85333197 ("worktree: make add <path> <branch>
dwim", 2017-11-26) which added it to git-worktree.

ad8d5104b4 checkout: add advice for ambiguous "checkout <branch>"
As the "checkout" documentation describes:

    If <branch> is not found but there does exist a tracking branch in
    exactly one remote (call it <remote>) with a matching name, treat
    as equivalent to [...] <remote>/<branch.

This is a really useful feature. The problem is that when you add
another remote (e.g. a fork), git won't find a unique branch name
anymore, and will instead print this unhelpful message:

    $ git checkout master
    error: pathspec 'master' did not match any file(s) known to git

Now it will, on my git.git checkout, print:

    $ ./git --exec-path=$PWD checkout master
    error: pathspec 'master' did not match any file(s) known to git.
    hint: 'master' matched more than one remote tracking branch.
    hint: We found 26 remotes with a reference that matched. So we fell back
    hint: on trying to resolve the argument as a path, but failed there too!
    hint:
    hint: If you meant to check out a remote tracking branch on, e.g. 'origin',
    hint: you can do so by fully qualifying the name with the --track option:
    hint:
    hint:     git checkout --track origin/<name>

Note that the "error: pathspec[...]" message is still printed. This is
because whatever else checkout may have tried earlier, its final
fallback is to try to resolve the argument as a path. E.g. in this
case:

    $ ./git --exec-path=$PWD checkout master pu
    error: pathspec 'master' did not match any file(s) known to git.
    error: pathspec 'pu' did not match any file(s) known to git.

There we don't print the "hint:" implicitly due to earlier logic
around the DWIM fallback. That fallback is only used if it looks like
we have one argument that might be a branch.

I can't think of an intrinsic reason for why we couldn't in some
future change skip printing the "error: pathspec[...]" error. However,
to do so we'd need to pass something down to checkout_paths() to make
it suppress printing an error on its own, and for us to be confident
that we're not silencing cases where those errors are meaningful.

I don't think that's worth it since determining whether that's the
case could easily change due to future changes in the checkout logic.

3ac68a93fd help: add --config to list all available config
Sometimes it helps to list all available config vars so the user can
search for something they want. The config man page can also be used
but it's harder to search if you want to focus on the variable name,
for example.

This is not the best way to collect the available config since it's
not precise. Ideally we should have a centralized list of config in C
code (pretty much like 'struct option'), but that's a lot more work.
This will do for now.

fb3010c31f show-index: update documentation for index v2
Commit 32637cdf4a (show-index.c: learn about index v2,
2007-04-09) changed the output format of show-index to
include the object CRC32 but didn't update the
documentation. Let's fix that and generally describe the
output in more detail.

There are a few other fixes here while we're rewording:

 - refer to index-pack along with pack-objects, since either
   can create .idx files

 - use "linkgit:" for referring to other commands

 - expand the bit about verify-pack, giving reasons why you
   might want this command instead. I almost omitted this
   entirely, but referring to verify-pack might help a
   reader who is looking for more information.

123f631761 git-p4: add unshelve command
This can be used to "unshelve" a shelved P4 commit into
a git commit.

For example:

  $ git p4 unshelve 12345

The resulting commit ends up in the branch:
   refs/remotes/p4/unshelved/12345

If that branch already exists, it is renamed - for example
the above branch would be saved as p4/unshelved/12345.1.

git-p4 checks that the shelved changelist is based on files
which are at the same Perforce revision as the origin branch
being used for the unshelve (HEAD by default). If they are not,
it will refuse to unshelve. This is to ensure that the unshelved
change does not contain other changes mixed-in.

The reference branch can be changed manually with the "--origin"
option.

The change adds a new Unshelve command class. This just runs the
existing P4Sync code tweaked to handle a shelved changelist.

3301d36b29 completion: add and use --list-cmds=alias
By providing aliases via --list-cmds=, we could simplify command
collection code in the script. We only issue one git command. Before
this patch that is "git config", after it's "git --list-cmds=". In
"git help" completion case we actually reduce one "git" process (for
getting guides) but that call was added in this series so it does not
really count.

A couple of bash functions are removed because they are not needed
anymore. __git_compute_all_commands() and $__git_all_commands stay
because they are still needed for completing pager.* config and
without "alias" group, the result is still cacheable.

There is a slight (good) change in _git_help() with this patch: before
"git help <tab>" shows external commands (as in _not_ part of git) as
well as part of $__git_all_commands. We have finer control over
command listing now and can exclude that because we can't provide a
man page for external commands anyway.

63eae83f8f help: add "-a --verbose" to list all commands with synopsis
This lists all recognized commands [1] by category. The group order
follows closely git.txt.

[1] We may actually show commands that are not built (e.g. if you set
NO_PERL you don't have git-instaweb but it's still listed here). I
ignore the problem because on Linux a git package could be split
anyway. The "git-core" package may not contain git-instaweb even if
it's built because it may end up in a separate package. We can't know
anyway.

6bb2dc0b94 completion: implement and use --list-cmds=main,others
This is part of the effort to break down and provide commands by
category in machine-readable form. This could be helpful later on when
completion script switches to use --list-cmds for selecting
completable commands. It would be much easier for the user to choose
to complete _all_ commands instead of the default selection by passing
different values to --list-cmds in git-completino.bash.

While at there, replace "git help -a" in git-completion.bash with
--list-cmds since it's better suited for this task.

e8b2dc2c2a add status config and command line options for rename detection
After performing a merge that has conflicts git status will, by default,
attempt to detect renames which causes many objects to be examined.  In a
virtualized repo, those objects do not exist locally so the rename logic
triggers them to be fetched from the server. This results in the status call
taking hours to complete on very large repos vs seconds with this patch.

Add a new config status.renames setting to enable turning off rename
detection during status and commit.  This setting will default to the value
of diff.renames.

Add a new config status.renamelimit setting to to enable bounding the time
spent finding out inexact renames during status and commit.  This setting
will default to the value of diff.renamelimit.

Add --no-renames command line option to status that enables overriding the
config setting from the command line. Add --find-renames[=<n>] command line
option to status that enables detecting renames and optionally setting the
similarity index.

5cc044e025 get_short_oid: sort ambiguous objects by type, then SHA-1
Change the output emitted when an ambiguous object is encountered so
that we show tags first, then commits, followed by trees, and finally
blobs. Within each type we show objects in hashcmp() order. Before
this change the objects were only ordered by hashcmp().

The reason for doing this is that the output looks better as a result,
e.g. the v2.17.0 tag before this change on "git show e8f2" would
display:

    hint: The candidates are:
    hint:   e8f2093055 tree
    hint:   e8f21caf94 commit 2013-06-24 - bash prompt: print unique detached HEAD abbreviated object name
    hint:   e8f21d02f7 blob
    hint:   e8f21d577c blob
    hint:   e8f25a3a50 tree
    hint:   e8f26250fa commit 2017-02-03 - Merge pull request #996 from jeffhostetler/jeffhostetler/register_rename_src
    hint:   e8f2650052 tag v2.17.0
    hint:   e8f2867228 blob
    hint:   e8f28d537c tree
    hint:   e8f2a35526 blob
    hint:   e8f2bc0c06 commit 2015-05-10 - Documentation: note behavior for multiple remote.url entries
    hint:   e8f2cf6ec0 tree

Now we'll instead show:

    hint:   e8f2650052 tag v2.17.0
    hint:   e8f21caf94 commit 2013-06-24 - bash prompt: print unique detached HEAD abbreviated object name
    hint:   e8f26250fa commit 2017-02-03 - Merge pull request #996 from jeffhostetler/jeffhostetler/register_rename_src
    hint:   e8f2bc0c06 commit 2015-05-10 - Documentation: note behavior for multiple remote.url entries
    hint:   e8f2093055 tree
    hint:   e8f25a3a50 tree
    hint:   e8f28d537c tree
    hint:   e8f2cf6ec0 tree
    hint:   e8f21d02f7 blob
    hint:   e8f21d577c blob
    hint:   e8f2867228 blob
    hint:   e8f2a35526 blob

Since we show the commit data in the output that's nicely aligned once
we sort by object type. The decision to show tags before commits is
pretty arbitrary. I don't want to order by object_type since there
tags come last after blobs, which doesn't make sense if we want to
show the most important things first.

I could display them after commits, but it's much less likely that
we'll display a tag, so if there is one it makes sense to show it
prominently at the top.

A note on the implementation: Derrick rightly pointed out[1] that
we're bending over backwards here in get_short_oid() to first
de-duplicate the list, and then emit it, but could simply do it in one
step.

The reason for that is that oid_array_for_each_unique() doesn't
actually require that the array be sorted by oid_array_sort(), it just
needs to be sorted in some order that guarantees that all objects with
the same ID are adjacent to one another, which (barring a hash
collision, which'll be someone else's problem) the sort_ambiguous()
function does.

I agree that would be simpler for this code, and had forgotten why I
initially wrote it like this[2]. But on further reflection I think
it's better to do more work here just so we're not underhandedly using
the oid-array API where we lie about the list being sorted. That would
break any subsequent use of oid_array_lookup() in subtle ways.

I could get around that by hacking the API itself to support this
use-case and documenting it, which I did as a WIP patch in [3], but I
think it's too much code smell just for this one call site. It's
simpler for the API to just introduce a oid_array_for_each() function
to eagerly spew out the list without sorting or de-duplication, and
then do the de-duplication and sorting in two passes.

ba95710a3b {fetch,upload}-pack: support filter in protocol v2
The fetch-pack/upload-pack protocol v2 was developed independently of
the filter parameter (used in partial fetches), thus it did not include
support for it. Add support for the filter parameter.

Like in the legacy protocol, the server advertises and supports "filter"
only if uploadpack.allowfilter is configured.

Like in the legacy protocol, the client continues with a warning if
"--filter" is specified, but the server does not advertise it.

7213c28818 git: add -P as a short option for --no-pager
It is possible to configure 'less', the pager, to use an alternate
screen to show the content, for example, by setting LESS=RS in the
environment. When it is closed in this configuration, it switches
back to the original screen, and all content is gone.

It is not uncommon to request that the output remains visible in
the terminal. For this, the option --no-pager can be used. But
it is a bit cumbersome to type, even when command completion is
available. Provide a short option, -P, to make the option more
easily accessible.

76a8788c14 doc: keep first level section header in upper case
When formatted as a man page, 1st section header is always in upper
case even if we write it otherwise. Make all 1st section headers
uppercase to keep it close to the final output.

This does affect html since case is kept there, but I still think it's
a good idea to maintain a consistent style for 1st section headers.

Some sections perhaps should become second sections instead, where
case is kept, and for better organization. I will update if anyone has
suggestions about this.

While at there I also make some header more consistent (e.g. examples
vs example) and fix a couple minor things here and there.

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.

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`.

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

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

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

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.

4c57a4f8fe git-submodule.txt: quote usage in monospace, drop backslash
We tend to quote command line examples using `` to set them in a
monospace font. The immediate motivation for this patch is to get rid of
another instance of \--. As noted in the previous commits, \-- has a
tendency of rendering badly. Here, it renders ok (at least with
AsciiDoc 8.6.9 and Asciidoctor 1.5.4), but by getting rid of this
instance, we reduce the chances of \-- cropping up in places where it
matters more.

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.

933c758c7d doc: convert [\--] to [--]
Commit 1c262bb7b (doc: convert \--option to --option, 2015-05-13)
explains that we used to need to write \--option to play well with older
versions of AsciiDoc, but that we do not support such versions anymore
anyway, and that Asciidoctor literally renders \--.

With [\--], which is used to denote the optional separator between
revisions and paths, Asciidoctor renders the backslash literally.
Change all [\--] to [--]. This changes nothing for AsciiDoc version
8.6.9, but is an improvement for Asciidoctor version 1.5.4.

We use double-dashes in several list entries (\--::). In my testing, it
appears that we do need to use the backslash there, so leave those.

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).

you need to tell gc to do this explicitly (and probably on just a few

Add a config key that enables this mode when packs larger than a limit

--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.

(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'.

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.

directory in some situations. This makes sense if the program is part of
the repository but prevents searching via $PATH.

The old behaviour is still retained, but if the file does not exists, then
authors-prog is searched for in $PATH as any other command.

b84f767c8a commit-graph: add format document
Add document specifying the binary format for commit graphs. This
format allows for:

* New versions.
* New hash functions and hash lengths.
* Optional extensions.

Basic header information is followed by a binary table of contents
into "chunks" that include:

* An ordered list of commit object IDs.
* A 256-entry fanout into that list of OIDs.
* 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
very rare.)

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.

a852ec7f27 rebase: extend --signoff support
Allow --signoff to be used with --interactive and --merge. In
interactive mode only commits marked to be picked, edited or reworded
will be signed off.

The main motivation for this patch was to allow one to run 'git rebase
--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).

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
nothing else than consistency and simplicity), but that
would create backwards compatibility issues. For some
discussion, see this thread:

  https://public-inbox.org/git/slrnkldd3g.1l4.jan@majutsushi.net/

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.
