CONFIGURATION FILE
------------------
The Git configuration file contains a number of variables that affect
worktree: add per-worktree config files A new repo extension is added, worktreeConfig. When it is present: - Repository config reading by default includes $GIT_DIR/config _and_ $GIT_DIR/config.worktree. "config" file remains shared in multiple worktree setup. - The special treatment for core.bare and core.worktree, to stay effective only in main worktree, is gone. These config settings are supposed to be in config.worktree. This extension is most useful in multiple worktree setup because you now have an option to store per-worktree config (which is either .git/config.worktree for main worktree, or .git/worktrees/xx/config.worktree for linked ones). This extension can be used in single worktree mode, even though it's pretty much useless (but this can happen after you remove all linked worktrees and move back to single worktree). "git config" reads from both "config" and "config.worktree" by default (i.e. without either --user, --file...) when this extension is present. Default writes still go to "config", not "config.worktree". A new option --worktree is added for that (*). Since a new repo extension is introduced, existing git binaries should refuse to access to the repo (both from main and linked worktrees). So they will not misread the config file (i.e. skip the config.worktree part). They may still accidentally write to the config file anyway if they use with "git config --file <path>". This design places a bet on the assumption that the majority of config variables are shared so it is the default mode. A safer move would be default writes go to per-worktree file, so that accidental changes are isolated. (*) "git config --worktree" points back to "config" file when this extension is not present and there is only one worktree so that it works in any both single and multiple worktree setups.

the Git commands' behavior. The files `.git/config` and optionally
`config.worktree` (see the "CONFIGURATION FILE" section of
linkgit:git-worktree[1]) in each repository are used to store the
configuration for that repository, and `$HOME/.gitconfig` is used to
store a per-user configuration as fallback values for the `.git/config`
file. The file `/etc/gitconfig` can be used to store a system-wide
default configuration.
The configuration variables are used by both the Git plumbing
and the porcelains. The variables are divided into sections, wherein
the fully qualified variable name of the variable itself is the last
dot-separated segment and the section name is everything before the last
dot. The variable names are case-insensitive, allow only alphanumeric
characters and `-`, and must start with an alphabetic character. Some
variables may appear multiple times; we say then that the variable is
multivalued.
Syntax
~~~~~~
The syntax is fairly flexible and permissive; whitespaces are mostly
ignored. The '#' and ';' characters begin comments to the end of line,
blank lines are ignored.
The file consists of sections and variables. A section begins with
the name of the section in square brackets and continues until the next
section begins. Section names are case-insensitive. Only alphanumeric

In asciidoc, the single quotes provide emphasis, literal text should be distintive enough. Change "`...`" to `...`.

All instances are around command line arguments where no in-shell quoting should be necessary. gitcli.txt Change `"..."` to `...`. All instances are around command line examples or single command arguments. They do not semanticly belong inside the literal text, and they are not needed outside it. glossary-content.txt user-manual.txt Change "`...`" to `...`. All instances were around command lines.

characters, `-` and `.` are allowed in section names. Each variable
must belong to some section, which means that there must be a section
header before the first setting of a variable.
Sections can be further divided into subsections. To begin a subsection
put its name in double quotes, separated by space from the section name,
in the section header, like in the example below:
--------
[section "subsection"]
--------
Subsection names are case sensitive and can contain any characters except
newline and the null byte. Doublequote `"` and backslash can be included
by escaping them as `\"` and `\\`, respectively. Backslashes preceding
other characters are dropped when reading; for example, `\t` is read as
`t` and `\0` is read as `0` Section headers cannot span multiple lines.
Variables may belong directly to a section or to a given subsection. You
can have `[section]` if you have `[section "subsection"]`, but you don't
need to.
There is also a deprecated `[section.subsection]` syntax. With this
syntax, the subsection name is converted to lower-case and is also
compared case sensitively. These subsection names follow the same
restrictions as section names.
All the other lines (and the remainder of the line after the section
header) are recognized as setting variables, in the form
'name = value' (or just 'name', which is a short-hand to say that
the variable is the boolean "true").
The variable names are case-insensitive, allow only alphanumeric characters
and `-`, and must start with an alphabetic character.
A line that defines a value can be continued to the next line by
ending it with a `\`; the backquote and the end-of-line are
stripped. Leading whitespaces after 'name =', the remainder of the
line after the first comment character '#' or ';', and trailing
whitespaces of the line are discarded unless they are enclosed in
double quotes. Internal whitespaces within the value are retained
verbatim.
Inside double quotes, double quote `"` and backslash `\` characters
must be escaped: use `\"` for `"` and `\\` for `\`.

The following escape sequences (beside `\"` and `\\`) are recognized:
`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
and `\b` for backspace (BS). Other char escape sequences (including octal
escape sequences) are invalid.
config: add include directive It can be useful to split your ~/.gitconfig across multiple files. For example, you might have a "main" file which is used on many machines, but a small set of per-machine tweaks. Or you may want to make some of your config public (e.g., clever aliases) while keeping other data back (e.g., your name or other identifying information). Or you may want to include a number of config options in some subset of your repos without copying and pasting (e.g., you want to reference them from the .git/config of participating repos). This patch introduces an include directive for config files. It looks like: [include] path = /path/to/file This is syntactically backwards-compatible with existing git config parsers (i.e., they will see it as another config entry and ignore it unless you are looking up include.path). The implementation provides a "git_config_include" callback which wraps regular config callbacks. Callers can pass it to git_config_from_file, and it will transparently follow any include directives, passing all of the discovered options to the real callback. Include directives are turned on automatically for "regular" git config parsing. This includes calls to git_config, as well as calls to the "git config" program that do not specify a single file (e.g., using "-f", "--global", etc). They are not turned on in other cases, including: 1. Parsing of other config-like files, like .gitmodules. There isn't a real need, and I'd rather be conservative and avoid unnecessary incompatibility or confusion. 2. Reading single files via "git config". This is for two reasons: a. backwards compatibility with scripts looking at config-like files. b. inspection of a specific file probably means you care about just what's in that file, not a general lookup for "do we have this value anywhere at all". If that is not the case, the caller can always specify "--includes". 3. Writing files via "git config"; we want to treat include.* variables as literal items to be copied (or modified), and not expand them. So "git config --unset-all foo.bar" would operate _only_ on .git/config, not any of its included files (just as it also does not operate on ~/.gitconfig).

Includes
~~~~~~~~
The `include` and `includeIf` sections allow you to include config
directives from another source. These sections behave identically to
each other with the exception that `includeIf` sections may be ignored
if their condition does not evaluate to true; see "Conditional includes"
below.
You can include a config file from another by setting the special
`include.path` (or `includeIf.*.path`) variable to the name of the file
to be included. The variable takes a pathname as its value, and is
subject to tilde expansion. These variables can be given multiple times.
The contents of the included file are inserted immediately, as if they
had been found at the location of the include directive. If the value of the
variable is a relative path, the path is considered to
be relative to the configuration file in which the include directive
was found. See below for examples.
config: add conditional include Sometimes a set of repositories want to share configuration settings among themselves that are distinct from other such sets of repositories. A user may work on two projects, each of which have multiple repositories, and use one user.email for one project while using another for the other. Setting $GIT_DIR/.config works, but if the penalty of forgetting to update $GIT_DIR/.config is high (especially when you end up cloning often), it may not be the best way to go. Having the settings in ~/.gitconfig, which would work for just one set of repositories, would not well in such a situation. Having separate ${HOME}s may add more problems than it solves. Extend the include.path mechanism that lets a config file include another config file, so that the inclusion can be done only when some conditions hold. Then ~/.gitconfig can say "include config-project-A only when working on project-A" for each project A the user works on. In this patch, the only supported grouping is based on $GIT_DIR (in absolute path), so you would need to group repositories by directory, or something like that to take advantage of it. We already have include.path for unconditional includes. This patch goes with includeIf.<condition>.path to make it clearer that a condition is required. The new config has the same backward compatibility approach as include.path: older git versions that don't understand includeIf will simply ignore them.

Conditional includes
~~~~~~~~~~~~~~~~~~~~
You can include a config file from another conditionally by setting a
`includeIf.<condition>.path` variable to the name of the file to be
included.

The condition starts with a keyword followed by a colon and some data
whose format and meaning depends on the keyword. Supported keywords
are:
`gitdir`::
The data that follows the keyword `gitdir:` is used as a glob
pattern. If the location of the .git directory matches the
pattern, the include condition is met.
+
The .git location may be auto-discovered, or come from `$GIT_DIR`
environment variable. If the repository is auto discovered via a .git
file (e.g. from submodules, or a linked worktree), the .git location
would be the final location where the .git directory is, not where the
.git file is.
+
The pattern can contain standard globbing wildcards and two additional
ones, `**/` and `/**`, that can match multiple path components. Please
refer to linkgit:gitignore[5] for details. For convenience:
* If the pattern starts with `~/`, `~` will be substituted with the
content of the environment variable `HOME`.
* If the pattern starts with `./`, it is replaced with the directory
containing the current config file.
* If the pattern does not start with either `~/`, `./` or `/`, `**/`
will be automatically prepended. For example, the pattern `foo/bar`
becomes `**/foo/bar` and would match `/any/path/to/foo/bar`.
* If the pattern ends with `/`, `**` will be automatically added. For
example, the pattern `foo/` becomes `foo/**`. In other words, it
matches "foo" and everything inside, recursively.
`gitdir/i`::
This is the same as `gitdir` except that matching is done
case-insensitively (e.g. on case-insensitive file systems)

`onbranch`::
The data that follows the keyword `onbranch:` is taken to be a
pattern with standard globbing wildcards and two additional
ones, `**/` and `/**`, that can match multiple path components.
If we are in a worktree where the name of the branch that is
currently checked out matches the pattern, the include condition
is met.
+
If the pattern ends with `/`, `**` will be automatically added. For
example, the pattern `foo/` becomes `foo/**`. In other words, it matches
all branches that begin with `foo/`. This is useful if your branches are
organized hierarchically and you would like to apply a configuration to
all the branches in that hierarchy.

A few more notes on matching via `gitdir` and `gitdir/i`:
* Symlinks in `$GIT_DIR` are not resolved before matching.
* Both the symlink & realpath versions of paths will be matched
outside of `$GIT_DIR`. E.g. if ~/git is a symlink to
/mnt/storage/git, both `gitdir:~/git` and `gitdir:/mnt/storage/git`
will match.
+
This was not the case in the initial release of this feature in
v2.13.0, which only matched the realpath version. Configuration that
wants to be compatible with the initial release of this feature needs
to either specify only the realpath version, or both versions.

Values
~~~~~~
Values of many variables are treated as a simple string, but there
are variables that take values of specific types and there are rules
as to how to spell them.
boolean::
When a variable is said to take a boolean value, many
synonyms are accepted for 'true' and 'false'; these are all
case-insensitive.
true;; Boolean true literals are `yes`, `on`, `true`,
and `1`. Also, a variable defined without `= <value>`
is taken as true.
false;; Boolean false literals are `no`, `off`, `false`,
`0` and the empty string.
+
When converting a value to its canonical form using the `--type=bool` type
specifier, 'git config' will ensure that the output is "true" or
"false" (spelled in lowercase).
integer::
The value for many variables that specify various sizes can
be suffixed with `k`, `M`,... to mean "scale the number by
1024", "by 1024x1024", etc.
color::
The value for a variable that takes a color is a list of
colors (at most two, one for foreground and one for background)
and attributes (as many as you want), separated by spaces.
+
The basic colors accepted are `normal`, `black`, `red`, `green`, `yellow`,
`blue`, `magenta`, `cyan` and `white`. The first color given is the
foreground; the second is the background. All the basic colors except
`normal` have a bright variant that can be speficied by prefixing the
color with `bright`, like `brightred`.
+
Colors may also be given as numbers between 0 and 255; these use ANSI
256-color mode (but note that not all terminals may support this). If
your terminal supports it, you may also specify 24-bit RGB values as
hex, like `#ff0ab3`.
+
The accepted attributes are `bold`, `dim`, `ul`, `blink`, `reverse`,
`italic`, and `strike` (for crossed-out or "strikethrough" letters).
The position of any attributes with respect to the colors
(before, after, or in between), doesn't matter. Specific attributes may
be turned off by prefixing them with `no` or `no-` (e.g., `noreverse`,
`no-ul`, etc).
+
An empty color string produces no color effect at all. This can be used
to avoid coloring specific elements without disabling color entirely.
+
For git's pre-defined color slots, the attributes are meant to be reset
at the beginning of each item in the colored output. So setting
`color.decorate.branch` to `black` will paint that branch name in a
plain `black`, even if the previous thing on the same output line (e.g.
opening parenthesis before the list of branch names in `log --decorate`
output) is set to be painted with `bold` or some other attribute.
However, custom log formats may do more complicated and layered
coloring, and the negated forms may be useful there.
pathname::
A variable that takes a pathname value can be given a
string that begins with "`~/`" or "`~user/`", and the usual
tilde expansion happens to such a string: `~/`
is expanded to the value of `$HOME`, and `~user/` to the
specified user's home directory.
Variables
~~~~~~~~~
Note that this list is non-comprehensive and not necessarily complete.
For command-specific variables, you will find a more detailed description
in the appropriate manual page.
Other git-related tools may and do use their own variables. When
inventing new variables for use in your own tool, make sure their
names do not conflict with those that are used by Git itself and
other popular tools, and describe them in your documentation.

add--interactive: allow custom diff highlighting programs The patch hunk selector of add--interactive knows how ask git for colorized diffs, and correlate them with the uncolored diffs we apply. But there's not any way for somebody who uses a diff-filter tool like contrib's diff-highlight to see their normal highlighting. This patch lets users define an arbitrary shell command to pipe the colorized diff through. The exact output shouldn't matter (since we just show the result to humans) as long as it is line-compatible with the original diff (so that hunk-splitting can split the colorized version, too). I left two minor issues with the new system that I don't think are worth fixing right now, but could be done later: 1. We only filter colorized diffs. Theoretically a user could want to filter a non-colorized diff, but I find it unlikely in practice. Users who are doing things like diff-highlighting are likely to want color, too. 2. add--interactive will re-colorize a diff which has been hand-edited, but it won't have run through the filter. Fixing this is conceptually easy (just pipe the diff through the filter), but practically hard to do without using tempfiles (it would need to feed data to and read the result from the filter without deadlocking; this raises portability questions with respect to Windows). I've punted on both issues for now, and if somebody really cares later, they can do a patch on top. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

pack-bitmap: implement optional name_hash cache When we use pack bitmaps rather than walking the object graph, we end up with the list of objects to include in the packfile, but we do not know the path at which any tree or blob objects would be found. In a recently packed repository, this is fine. A fetch would use the paths only as a heuristic in the delta compression phase, and a fully packed repository should not need to do much delta compression. As time passes, though, we may acquire more objects on top of our large bitmapped pack. If clients fetch frequently, then they never even look at the bitmapped history, and all works as usual. However, a client who has not fetched since the last bitmap repack will have "have" tips in the bitmapped history, but "want" newer objects. The bitmaps themselves degrade gracefully in this circumstance. We manually walk the more recent bits of history, and then use bitmaps when we hit them. But we would also like to perform delta compression between the newer objects and the bitmapped objects (both to delta against what we know the user already has, but also between "new" and "old" objects that the user is fetching). The lack of pathnames makes our delta heuristics much less effective. This patch adds an optional cache of the 32-bit name_hash values to the end of the bitmap file. If present, a reader can use it to match bitmapped and non-bitmapped names during delta compression. Here are perf results for p5310: Test origin/master HEAD^ HEAD ------------------------------------------------------------------------------------------------- 5310.2: repack to disk 36.81(37.82+1.43) 47.70(48.74+1.41) +29.6% 47.75(48.70+1.51) +29.7% 5310.3: simulated clone 30.78(29.70+2.14) 1.08(0.97+0.10) -96.5% 1.07(0.94+0.12) -96.5% 5310.4: simulated fetch 3.16(6.10+0.08) 3.54(10.65+0.06) +12.0% 1.70(3.07+0.06) -46.2% 5310.6: partial bitmap 36.76(43.19+1.81) 6.71(11.25+0.76) -81.7% 4.08(6.26+0.46) -88.9% You can see that the time spent on an incremental fetch goes down, as our delta heuristics are able to do their work. And we save time on the partial bitmap clone for the same reason.

repack: add `repack.packKeptObjects` config var The git-repack command always passes `--honor-pack-keep` to pack-objects. This has traditionally been a good thing, as we do not want to duplicate those objects in a new pack, and we are not going to delete the old pack. However, when bitmaps are in use, it is important for a full repack to include all reachable objects, even if they may be duplicated in a .keep pack. Otherwise, we cannot generate the bitmaps, as the on-disk format requires the set of objects in the pack to be fully closed. Even if the repository does not generally have .keep files, a simultaneous push could cause a race condition in which a .keep file exists at the moment of a repack. The repack may try to include those objects in one of two situations: 1. The pushed .keep pack contains objects that were already in the repository (e.g., blobs due to a revert of an old commit). 2. Receive-pack updates the refs, making the objects reachable, but before it removes the .keep file, the repack runs. In either case, we may prefer to duplicate some objects in the new, full pack, and let the next repack (after the .keep file is cleaned up) take care of removing them. This patch introduces both a command-line and config option to disable the `--honor-pack-keep` option. By default, it is triggered when pack.writeBitmaps (or `--write-bitmap-index` is turned on), but specifying it explicitly can override the behavior (e.g., in cases where you prefer .keep files to bitmaps, but only when they are present). Note that this option just disables the pack-objects behavior. We still leave packs with a .keep in place, as we do not necessarily know that we have duplicated all of their objects.
