CONFIGURATION FILE
------------------
The git configuration file contains a number of variables that affect
the git command's behavior. `.git/config` file for each repository
is used to store the information for that repository, and
`$HOME/.gitconfig` is used to store per user information to give
fallback values for `.git/config` file. The file `/etc/gitconfig`
can be used to store system-wide defaults.
They can be used by both the git plumbing
and the porcelains. The variables are divided into sections, where
in the fully qualified variable name 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 and only alphanumeric
characters are allowed. Some variables may appear multiple times.
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 not case sensitive. Only alphanumeric
characters, '`-`' and '`.`' are allowed in section names. Each variable
must belong to some section, which means that there must be section
header before 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 example below:
--------
[section "subsection"]
--------
Subsection names can contain any characters except newline (doublequote
'`"`' and backslash have to be escaped as '`\"`' and '`\\`',
respectively) and are case sensitive. Section header 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 (case insensitive) alternative `[section.subsection]` syntax.
In this syntax subsection names follow the same restrictions as for section
name.
All the other lines are recognized as setting variables, in the form
'name = value'. If there is no equal sign on the line, the entire line
is taken as 'name' and the variable is recognized as boolean "true".
The variable names are case-insensitive and only alphanumeric
characters and '`-`' are allowed. There can be more than one value
for a given variable; we say then that variable is multivalued.
Leading and trailing whitespace in a variable value is discarded.
Internal whitespace within a variable value is retained verbatim.
The values following the equals sign in variable assign are all either
a string, an integer, or a boolean. Boolean values may be given as yes/no,
0/1 or true/false. Case is not significant in boolean values, when
converting value to the canonical form using '--bool' type specifier;
`git-config` will ensure that the output is "true" or "false".
String values may be entirely or partially enclosed in double quotes.
You need to enclose variable value in double quotes if you want to
preserve leading or trailing whitespace, or if variable value contains
beginning of comment characters (if it contains '#' or ';').
Double quote '`"`' and backslash '`\`' characters in variable value 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). No other char escape sequence, nor octal
char sequences are valid.
Variable value ending in a '`\`' is continued on the next line in the
customary UNIX fashion.
Some variables may require special value format.
Example
~~~~~~~
# Core variables
[core]
; Don't trust file modes
filemode = false
# Our diff algorithm
[diff]
external = "/usr/local/bin/gnu-diff -u"
renames = true

# Proxy settings

gitProxy="ssh" for "kernel.org"
gitProxy=default-proxy ; for the rest
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. You will find a description of non-core
porcelain configuration variables in the respective porcelain documentation.
core.fileMode::
If false, the executable bit differences between the index and
the working copy are ignored; useful on broken filesystems like FAT.
See linkgit:git-update-index[1]. True by default.
core.quotepath::
The commands that output paths (e.g. `ls-files`,
`diff`), when not given the `-z` option, will quote
"unusual" characters in the pathname by enclosing the
pathname in a double-quote pair and with backslashes the
same way strings in C source code are quoted. If this
variable is set to false, the bytes higher than 0x80 are
not quoted but output as verbatim. Note that double
quote, backslash and control characters are always
quoted without `-z` regardless of the setting of this
variable.
core.autocrlf::
If true, makes git convert `CRLF` at the end of lines in text files to
`LF` when reading from the filesystem, and convert in reverse when
writing to the filesystem. The variable can be set to
'input', in which case the conversion happens only while
reading from the filesystem but files are written out with
`LF` at the end of lines. Currently, which paths to consider
"text" (i.e. be subjected to the autocrlf mechanism) is
decided purely based on the contents.
safecrlf: Add mechanism to warn about irreversible crlf conversions CRLF conversion bears a slight chance of corrupting data. autocrlf=true will convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and CRLF before the commit cannot be recreated by git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data. If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell git that this file is binary and git will handle the file appropriately. Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data. This patch adds a mechanism that can either warn the user about an irreversible conversion or can even refuse to convert. The mechanism is controlled by the variable core.safecrlf, with the following values: - false: disable safecrlf mechanism - warn: warn about irreversible conversions - true: refuse irreversible conversions The default is to warn. Users are only affected by this default if core.autocrlf is set. But the current default of git is to leave core.autocrlf unset, so users will not see warnings unless they deliberately chose to activate the autocrlf mechanism. The safecrlf mechanism's details depend on the git command. The general principles when safecrlf is active (not false) are: - we warn/error out if files in the work tree can modified in an irreversible way without giving the user a chance to backup the original file. - for read-only operations that do not modify files in the work tree we do not not print annoying warnings. There are exceptions. Even though... - "git add" itself does not touch the files in the work tree, the next checkout would, so the safety triggers; - "git apply" to update a text file with a patch does touch the files in the work tree, but the operation is about text files and CRLF conversion is about fixing the line ending inconsistencies, so the safety does not trigger; - "git diff" itself does not touch the files in the work tree, it is often run to inspect the changes you intend to next "git add". To catch potential problems early, safety triggers. The concept of a safety check was originally proposed in a similar way by Linus Torvalds.

core.safecrlf::
If true, makes git check if converting `CRLF` as controlled by
`core.autocrlf` is reversible. Git will verify if a command
modifies a file in the work tree either directly or indirectly.
For example, committing a file followed by checking out the
same file should yield the original file in the work tree. If
this is not the case for the current setting of
`core.autocrlf`, git will reject the file. The variable can
be set to "warn", in which case git will only warn about an
irreversible conversion but continue the operation.
+
CRLF conversion bears a slight chance of corrupting data.
autocrlf=true will convert CRLF to LF during commit and LF to
CRLF during checkout. A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by git. For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.
+
If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes. Right
after committing you still have the original file in your work
tree and this file is not yet corrupted. You can explicitly tell
git that this file is binary and git will handle the file
appropriately.
+
Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished. In both cases CRLFs are removed
in an irreversible way. For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.
+
Note, this safety check does not mean that a checkout will generate a
file identical to the original file for a different setting of
`core.autocrlf`, but only for the current one. For example, a text
file with `LF` would be accepted with `core.autocrlf=input` and could
later be checked out with `core.autocrlf=true`, in which case the
resulting file would contain `CRLF`, although the original file
contained `LF`. However, in both work trees the line endings would be
consistent, that is either all `LF` or all `CRLF`, but never mixed. A
file with mixed line endings would be reported by the `core.safecrlf`
mechanism.
core.symlinks::
If false, symbolic links are checked out as small plain files that
contain the link text. linkgit:git-update-index[1] and
linkgit:git-add[1] will not change the recorded type to regular
file. Useful on filesystems like FAT that do not support
symbolic links. True by default.
core.gitProxy::
A "proxy command" to execute (as 'command host port') instead
of establishing direct connection to the remote server when
using the git protocol for fetching. If the variable value is
in the "COMMAND for DOMAIN" format, the command is applied only
on hostnames ending with the specified domain string. This variable
may be set multiple times and is matched in the given order;
the first match wins.
+
Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
(which always applies universally, without the special "for"
handling).
core.ignoreStat::
The working copy files are assumed to stay unchanged until you
mark them otherwise manually - Git will not detect the file changes
by lstat() calls. This is useful on systems where those are very
slow, such as Microsoft Windows. See linkgit:git-update-index[1].
False by default.
core.preferSymlinkRefs::
Instead of the default "symref" format for HEAD
and other symbolic reference files, use symbolic links.
This is sometimes needed to work with old scripts that
expect HEAD to be a symbolic link.
core.bare::
If true this repository is assumed to be 'bare' and has no
working directory associated with it. If this is the case a
number of commands that require a working directory will be
disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
+
This setting is automatically guessed by linkgit:git-clone[1] or
linkgit:git-init[1] when the repository was created. By default a
repository that ends in "/.git" is assumed to be not bare (bare =
false), while all other repositories are assumed to be bare (bare
= true).
introduce GIT_WORK_TREE to specify the work tree setup_gdg is used as abbreviation for setup_git_directory_gently. The work tree can be specified using the environment variable GIT_WORK_TREE and the config option core.worktree (the environment variable has precendence over the config option). Additionally there is a command line option --work-tree which sets the environment variable. setup_gdg does the following now: GIT_DIR unspecified repository in .git directory parent directory of the .git directory is used as work tree, GIT_WORK_TREE is ignored GIT_DIR unspecified repository in cwd GIT_DIR is set to cwd see the cases with GIT_DIR specified what happens next and also see the note below GIT_DIR specified GIT_WORK_TREE/core.worktree unspecified cwd is used as work tree GIT_DIR specified GIT_WORK_TREE/core.worktree specified the specified work tree is used Note on the case where GIT_DIR is unspecified and repository is in cwd: GIT_WORK_TREE is used but is_inside_git_dir is always true. I did it this way because setup_gdg might be called multiple times (e.g. when doing alias expansion) and in successive calls setup_gdg should do the same thing every time. Meaning of is_bare/is_inside_work_tree/is_inside_git_dir: (1) is_bare_repository A repository is bare if core.bare is true or core.bare is unspecified and the name suggests it is bare (directory not named .git). The bare option disables a few protective checks which are useful with a working tree. Currently this changes if a repository is bare: updates of HEAD are allowed git gc packs the refs the reflog is disabled by default (2) is_inside_work_tree True if the cwd is inside the associated working tree (if there is one), false otherwise. (3) is_inside_git_dir True if the cwd is inside the git directory, false otherwise. Before this patch is_inside_git_dir was always true for bare repositories. When setup_gdg finds a repository git_config(git_default_config) is always called. This ensure that is_bare_repository makes use of core.bare and does not guess even though core.bare is specified. inside_work_tree and inside_git_dir are set if setup_gdg finds a repository. The is_inside_work_tree and is_inside_git_dir functions will die if they are called before a successful call to setup_gdg.

core.logAllRefUpdates::
Enable the reflog. Updates to a ref <ref> is logged to the file
"$GIT_DIR/logs/<ref>", by appending the new and old
SHA1, the date/time and the reason of the update, but
only when the file exists. If this configuration
variable is set to true, missing "$GIT_DIR/logs/<ref>"
file is automatically created for branch heads.
+
This information can be used to determine what commit
was the tip of a branch "2 days ago".

This value is true by default in a repository that has
a working directory associated with it, and false by
default in a bare repository.
core.repositoryFormatVersion::
Internal variable identifying the repository format and layout
version.
core.sharedRepository::
When 'group' (or 'true'), the repository is made shareable between
several users in a group (making sure all the files and objects are
group-writable). When 'all' (or 'world' or 'everybody'), the
repository will be readable by all users, additionally to being
group-shareable. When 'umask' (or 'false'), git will use permissions
reported by umask(2). See linkgit:git-init[1]. False by default.
core.warnAmbiguousRefs::
If true, git will warn you if the ref name you passed it is ambiguous
and might match multiple refs in the .git/refs/ tree. True by default.
core.compression::
Custom compression levels for objects and packs Add config variables pack.compression and core.loosecompression , and switch --compression=level to pack-objects. Loose objects will be compressed using core.loosecompression if set, else core.compression if set, else Z_BEST_SPEED. Packed objects will be compressed using --compression=level if seen, else pack.compression if set, else core.compression if set, else Z_DEFAULT_COMPRESSION. This is the "pack compression level". Loose objects added to a pack undeltified will be recompressed to the pack compression level if it is unequal to the current loose compression level by the preceding rules, or if the loose object was written while core.legacyheaders = true. Newly deltified loose objects are always compressed to the current pack compression level. Previously packed objects added to a pack are recompressed to the current pack compression level exactly when their deltification status changes, since the previous pack data cannot be reused. In either case, the --no-reuse-object switch from the first patch below will always force recompression to the current pack compression level, instead of assuming the pack compression level hasn't changed and pack data can be reused when possible.

+
Default is 16 MiB on all platforms. This should be reasonable
for all users/operating systems, except on the largest projects.
You probably do not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.
core.excludesfile::
In addition to '.gitignore' (per-directory) and
'.git/info/exclude', git looks into this file for patterns
of files which are not meant to be tracked. See
linkgit:gitignore[5].
core.editor::
Commands such as `commit` and `tag` that lets you edit
messages by launching an editor uses the value of this
variable when it is set, and the environment variable
`GIT_EDITOR` is not set. The order of preference is
`GIT_EDITOR` environment, `core.editor`, `VISUAL` and
`EDITOR` environment variables and then finally `vi`.
core.pager::
The command that git will use to paginate output. Can be overridden
with the `GIT_PAGER` environment variable.
core.whitespace::
A comma separated list of common whitespace problems to
notice. `git diff` will use `color.diff.whitespace` to
highlight them, and `git apply --whitespace=error` will
consider them as errors:
+
* `trailing-space` treats trailing whitespaces at the end of the line
as an error (enabled by default).
* `space-before-tab` treats a space character that appears immediately
before a tab character in the initial indent part of the line as an
error (enabled by default).
* `indent-with-non-tab` treats a line that is indented with 8 or more
space characters as an error (not enabled by default).
alias.*::
Command aliases for the linkgit:git[1] command wrapper - e.g.
after defining "alias.last = cat-file commit HEAD", the invocation
"git last" is equivalent to "git cat-file commit HEAD". To avoid
confusion and troubles with script usage, aliases that
hide existing git commands are ignored. Arguments are split by
spaces, the usual shell quoting and escaping is supported.
quote pair and a backslash can be used to quote them.
+
If the alias expansion is prefixed with an exclamation point,
it will be treated as a shell command. For example, defining
"alias.new = !gitk --all --not ORIG_HEAD", the invocation
"git new" is equivalent to running the shell command
"gitk --all --not ORIG_HEAD".
apply.whitespace::
Tells `git-apply` how to handle whitespaces, in the same way
as the '--whitespace' option. See linkgit:git-apply[1].
branch.autosetupmerge::
Tells `git-branch` and `git-checkout` to setup new branches
so that linkgit:git-pull[1] will appropriately merge from that
remote branch. Note that even if this option is not set,
this behavior can be chosen per-branch using the `--track`
and `--no-track` options. This option defaults to true.
branch.<name>.remote::
When in branch <name>, it tells `git fetch` which remote to fetch.
If this option is not given, `git fetch` defaults to remote "origin".
branch.<name>.merge::
When in branch <name>, it tells `git fetch` the default
refspec to be marked for merging in FETCH_HEAD. The value is
handled like the remote part of a refspec, and must match a
ref which is fetched from the remote given by
"branch.<name>.remote".
The merge information is used by `git pull` (which at first calls
`git fetch`) to lookup the default branch for merging. Without
this option, `git pull` defaults to merge the first refspec fetched.
Specify multiple values to get an octopus merge.
If you wish to setup `git pull` so that it merges into <name> from
another branch in the local repository, you can point
branch.<name>.merge to the desired branch, and use the special setting
`.` (a period) for branch.<name>.remote.
branch.<name>.mergeoptions::
Sets default options for merging into branch <name>. The syntax and
supported options are equal to that of linkgit:git-merge[1], but
option values containing whitespace characters are currently not
supported.
branch.<name>.rebase::
When true, rebase the branch <name> on top of the fetched branch,
instead of merging the default branch from the default remote.
*NOTE*: this is a possibly dangerous operation; do *not* use
it unless you understand the implications (see linkgit:git-rebase[1]
for details).
browser.<tool>.path::
Override the path for the given tool that may be used to
browse HTML help (see '-w' option in linkgit:git-help[1]) or a
working repository in gitweb (see linkgit:git-instaweb[1]).
clean.requireForce::
A boolean to make git-clean do nothing unless given -f
or -n. Defaults to true.
color.branch::
A boolean to enable/disable color in the output of
linkgit:git-branch[1]. May be set to `always`,
`false` (or `never`) or `auto` (or `true`), in which case colors are used
only when the output is to a terminal. Defaults to false.
color.branch.<slot>::
Use customized color for branch coloration. `<slot>` is one of
`current` (the current branch), `local` (a local branch),
`remote` (a tracking branch in refs/remotes/), `plain` (other
refs).
+
The value for these configuration variables is a list of colors (at most
two) and attributes (at most one), separated by spaces. The colors
accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
`blink` and `reverse`. The first color given is the foreground; the
second is the background. The position of the attribute, if any,
doesn't matter.
color.diff::
When set to `always`, always use colors in patch.
When false (or `never`), never. When set to `true` or `auto`, use
colors only when the output is to the terminal. Defaults to false.
color.diff.<slot>::
Use customized color for diff colorization. `<slot>` specifies
which part of the patch to use the specified color, and is one
of `plain` (context text), `meta` (metainformation), `frag`
(hunk header), `old` (removed lines), `new` (added lines),
`commit` (commit headers), or `whitespace` (highlighting
whitespace errors). The values of these variables may be specified as
in color.branch.<slot>.
color.interactive::
When set to `always`, always use colors for interactive prompts
and displays (such as those used by "git add --interactive").
When false (or `never`), never. When set to `true` or `auto`, use
colors only when the output is to the terminal. Defaults to false.
color.interactive.<slot>::
Use customized color for `git add --interactive`
output. `<slot>` may be `prompt`, `header`, or `help`, for
three distinct types of normal output from interactive
programs. The values of these variables may be specified as
in color.branch.<slot>.
color.pager::
A boolean to enable/disable colored output when the pager is in
use (default is true).
color.status::
A boolean to enable/disable color in the output of
linkgit:git-status[1]. May be set to `always`,
`false` (or `never`) or `auto` (or `true`), in which case colors are used
only when the output is to a terminal. Defaults to false.
color.status.<slot>::
Use customized color for status colorization. `<slot>` is
one of `header` (the header text of the status message),
`added` or `updated` (files which are added but not committed),
`changed` (files which are changed but not added in the index),
or `untracked` (files which are not tracked by git). The values of
these variables may be specified as in color.branch.<slot>.
commit.template::
Specify a file to use as the template for new commit messages.
color.ui::
When set to `always`, always use colors in all git commands which
are capable of colored output. When false (or `never`), never. When
set to `true` or `auto`, use colors only when the output is to the
terminal. When more specific variables of color.* are set, they always
take precedence over this setting. Defaults to false.
diff.autorefreshindex::
When using `git diff` to compare with work tree
files, do not consider stat-only change as changed.
Instead, silently run `git update-index --refresh` to
update the cached stat information for paths whose
contents in the work tree match the contents in the
index. This option defaults to true. Note that this
affects only `git diff` Porcelain, and not lower level
`diff` commands, such as `git diff-files`.
diff.external::
If this config variable is set, diff generation is not
performed using the internal diff machinery, but using the
given command. Note: if you want to use an external diff
program only on a subset of your files, you might want to
use linkgit:gitattributes[5] instead.
diff.renameLimit::
The number of files to consider when performing the copy/rename
detection; equivalent to the git diff option '-l'.
diff.renames::
Tells git to detect renames. If set to any boolean value, it
will enable basic rename detection. If set to "copies" or
"copy", it will detect copies, as well.
fetch.unpackLimit::
If the number of objects fetched over the git native
transfer is below this
limit, then the objects will be unpacked into loose object
files. However if the number of received objects equals or
exceeds this limit then the received pack will be stored as
a pack, after adding any missing delta bases. Storing the
pack from a push can make the push operation complete faster,
especially on slow filesystems. If not set, the value of
`transfer.unpackLimit` is used instead.
format.numbered::
A boolean which can enable sequence numbers in patch subjects.
Setting this option to "auto" will enable it only if there is
more than one patch. See --numbered option in
linkgit:git-format-patch[1].
format.headers::
Additional email headers to include in a patch to be submitted
by mail. See linkgit:git-format-patch[1].
format.suffix::
The default for format-patch is to output files with the suffix
`.patch`. Use this variable to change that suffix (make sure to
include the dot if you want it).
gc.aggressiveWindow::
The window size parameter used in the delta compression
algorithm used by 'git gc --aggressive'. This defaults
to 10.
gc.auto::
When there are approximately more than this many loose
objects in the repository, `git gc --auto` will pack them.
Some Porcelain commands use this command to perform a
light-weight garbage collection from time to time. The
default value is 6700. Setting this to 0 disables it.
gc.autopacklimit::
When there are more than this many packs that are not
marked with `*.keep` file in the repository, `git gc
--auto` consolidates them into one larger pack. The
default value is 20. Setting this to 0 disables it.
gc.packrefs::
`git gc` does not run `git pack-refs` in a bare repository by
default so that older dumb-transport clients can still fetch
from the repository. Setting this to `true` lets `git
gc` to run `git pack-refs`. Setting this to `false` tells
`git gc` never to run `git pack-refs`. The default setting is
`notbare`. Enable it only when you know you do not have to
support such clients. The default setting will change to `true`
at some stage, and setting this to `false` will continue to
prevent `git pack-refs` from being run from `git gc`.
gc.reflogexpire::
`git reflog expire` removes reflog entries older than
this time; defaults to 90 days.
gc.reflogexpireunreachable::
`git reflog expire` removes reflog entries older than
this time and are not reachable from the current tip;
defaults to 30 days.
gc.rerereresolved::
Records of conflicted merge you resolved earlier are
kept for this many days when `git rerere gc` is run.
The default is 60 days. See linkgit:git-rerere[1].
gc.rerereunresolved::
Records of conflicted merge you have not resolved are
kept for this many days when `git rerere gc` is run.
The default is 15 days. See linkgit:git-rerere[1].
rerere.enabled::
Activate recording of resolved conflicts, so that identical
conflict hunks can be resolved automatically, should they
be encountered again. linkgit:git-rerere[1] command is by
default enabled if you create `rr-cache` directory under
`$GIT_DIR`, but can be disabled by setting this option to false.
gitcvs.enabled::
Whether the CVS server interface is enabled for this repository.
See linkgit:git-cvsserver[1].
gitcvs.logfile::
Path to a log file where the CVS server interface well... logs
various stuff. See linkgit:git-cvsserver[1].
gitcvs.allbinary::
If true, all files are sent to the client in mode '-kb'. This
causes the client to treat all files as binary files which suppresses
any newline munging it otherwise might do. A work-around for the
fact that there is no way yet to set single files to mode '-kb'.
gitcvs.dbname::
Database used by git-cvsserver to cache revision information
derived from the git repository. The exact meaning depends on the
used database driver, for SQLite (which is the default driver) this
is a filename. Supports variable substitution (see
linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
Default: '%Ggitcvs.%m.sqlite'
gitcvs.dbdriver::
Used Perl DBI driver. You can specify any available driver
for this here, but it might not work. git-cvsserver is tested
with 'DBD::SQLite', reported to work with 'DBD::Pg', and
reported *not* to work with 'DBD::mysql'. Experimental feature.
May not contain double colons (`:`). Default: 'SQLite'.
See linkgit:git-cvsserver[1].
gitcvs.dbuser, gitcvs.dbpass::
Database user and password. Only useful if setting 'gitcvs.dbdriver',
since SQLite has no concept of database users and/or passwords.
'gitcvs.dbuser' supports variable substitution (see
linkgit:git-cvsserver[1] for details).
All gitcvs variables except for 'gitcvs.allbinary' can also be
specified as 'gitcvs.<access_method>.<varname>' (where 'access_method'
is one of "ext" and "pserver") to make them apply only for the given
access method.
help.browser::
Specify the browser that will be used to display help in the
'web' format. See linkgit:git-help[1].
help.format::
Override the default help format used by linkgit:git-help[1].
Values 'man', 'info', 'web' and 'html' are supported. 'man' is
the default. 'web' and 'html' are the same.
http.proxy::
Override the HTTP proxy, normally configured using the 'http_proxy'
environment variable (see linkgit:curl[1]). This can be overridden
on a per-remote basis; see remote.<name>.proxy
http.sslVerify::
Whether to verify the SSL certificate when fetching or pushing
over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
variable.
http.sslCert::
File containing the SSL certificate when fetching or pushing
over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
variable.
http.sslKey::
File containing the SSL private key when fetching or pushing
over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
variable.
http.sslCAInfo::
File containing the certificates to verify the peer with when
fetching or pushing over HTTPS. Can be overridden by the
'GIT_SSL_CAINFO' environment variable.
http.sslCAPath::
Path containing files with the CA certificates to verify the peer
with when fetching or pushing over HTTPS. Can be overridden
by the 'GIT_SSL_CAPATH' environment variable.
http.maxRequests::
How many HTTP requests to launch in parallel. Can be overridden
by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
http.lowSpeedLimit, http.lowSpeedTime::
If the HTTP transfer speed is less than 'http.lowSpeedLimit'
for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
'GIT_HTTP_LOW_SPEED_TIME' environment variables.
http.noEPSV::
A boolean which disables using of EPSV ftp command by curl.
This can helpful with some "poor" ftp servers which don't
support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
environment variable. Default is false (curl will use EPSV).
i18n.commitEncoding::
Character encoding the commit messages are stored in; git itself
does not care per se, but this information is necessary e.g. when
importing commits from emails or in the gitk graphical history
browser (and possibly at other places in the future or in other
porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
i18n.logOutputEncoding::
Character encoding the commit messages are converted to when
running `git-log` and friends.
instaweb.browser::
Specify the program that will be used to browse your working
repository in gitweb. See linkgit:git-instaweb[1].
instaweb.httpd::
The HTTP daemon command-line to start gitweb on your working
repository. See linkgit:git-instaweb[1].

If true the web server started by linkgit:git-instaweb[1] will
be bound to the local IP (127.0.0.1).
instaweb.modulepath::
The module path for an apache httpd used by linkgit:git-instaweb[1].
instaweb.port::
The port number to bind the gitweb httpd to. See
linkgit:git-instaweb[1].
log.showroot::
If true, the initial commit will be shown as a big creation event.
This is equivalent to a diff against an empty tree.
Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
normally hide the root commit will now show it. True by default.
merge.summary::
Whether to include summaries of merged commits in newly created
merge commit messages. False by default.
merge.tool::
Controls which merge resolution program is used by
linkgit:git-mergetool[1]. Valid values are: "kdiff3", "tkdiff",
"meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", and "opendiff".
merge.verbosity::
Controls the amount of output shown by the recursive merge
strategy. Level 0 outputs nothing except a final error
message if conflicts were detected. Level 1 outputs only
conflicts, 2 outputs conflicts and file changes. Level 5 and
above outputs debugging information. The default is level 2.
Can be overridden by 'GIT_MERGE_VERBOSITY' environment variable.
merge.<driver>.name::
Defines a human readable name for a custom low-level
merge driver. See linkgit:gitattributes[5] for details.
merge.<driver>.driver::
Defines the command that implements a custom low-level
merge driver. See linkgit:gitattributes[5] for details.
merge.<driver>.recursive::
Names a low-level merge driver to be used when
performing an internal merge between common ancestors.

window size is given on the command line. Defaults to 10.
pack.depth::
The maximum delta depth used by linkgit:git-pack-objects[1] when no
maximum depth is given on the command line. Defaults to 50.
pack.windowMemory::
The window memory size limit used by linkgit:git-pack-objects[1]
when no limit is given on the command line. The value can be
suffixed with "k", "m", or "g". Defaults to 0, meaning no
limit.
Custom compression levels for objects and packs Add config variables pack.compression and core.loosecompression , and switch --compression=level to pack-objects. Loose objects will be compressed using core.loosecompression if set, else core.compression if set, else Z_BEST_SPEED. Packed objects will be compressed using --compression=level if seen, else pack.compression if set, else core.compression if set, else Z_DEFAULT_COMPRESSION. This is the "pack compression level". Loose objects added to a pack undeltified will be recompressed to the pack compression level if it is unequal to the current loose compression level by the preceding rules, or if the loose object was written while core.legacyheaders = true. Newly deltified loose objects are always compressed to the current pack compression level. Previously packed objects added to a pack are recompressed to the current pack compression level exactly when their deltification status changes, since the previous pack data cannot be reused. In either case, the --no-reuse-object switch from the first patch below will always force recompression to the current pack compression level, instead of assuming the pack compression level hasn't changed and pack data can be reused when possible. This applies on top of the following patches from Nicolas Pitre: [PATCH] allow for undeltified objects not to be reused [PATCH] make "repack -f" imply "pack-objects --no-reuse-object" Signed-off-by: Dana L. How <danahow@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-05-09 22:56:50 +02:00
pack.compression::
An integer -1..9, indicating the compression level for objects
in a pack file. -1 is the zlib default. 0 means no
compression, and 1..9 are various speed/size tradeoffs, 9 being
slowest. If not set, defaults to core.compression. If that is
not set, defaults to -1, the zlib default, which is "a default
compromise between speed and compression (currently equivalent
to level 6)."
Custom compression levels for objects and packs Add config variables pack.compression and core.loosecompression , and switch --compression=level to pack-objects. Loose objects will be compressed using core.loosecompression if set, else core.compression if set, else Z_BEST_SPEED. Packed objects will be compressed using --compression=level if seen, else pack.compression if set, else core.compression if set, else Z_DEFAULT_COMPRESSION. This is the "pack compression level". Loose objects added to a pack undeltified will be recompressed to the pack compression level if it is unequal to the current loose compression level by the preceding rules, or if the loose object was written while core.legacyheaders = true. Newly deltified loose objects are always compressed to the current pack compression level. Previously packed objects added to a pack are recompressed to the current pack compression level exactly when their deltification status changes, since the previous pack data cannot be reused. In either case, the --no-reuse-object switch from the first patch below will always force recompression to the current pack compression level, instead of assuming the pack compression level hasn't changed and pack data can be reused when possible. This applies on top of the following patches from Nicolas Pitre: [PATCH] allow for undeltified objects not to be reused [PATCH] make "repack -f" imply "pack-objects --no-reuse-object" Signed-off-by: Dana L. How <danahow@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-05-09 22:56:50 +02:00
pack.deltaCacheSize::
The maximum memory in bytes used for caching deltas in
linkgit:git-pack-objects[1].
A value of 0 means no limit. Defaults to 0.
pack.deltaCacheLimit::
The maximum size of a delta, that is cached in
linkgit:git-pack-objects[1]. Defaults to 1000.
pack.threads::
Specifies the number of threads to spawn when searching for best
delta matches. This requires that linkgit:git-pack-objects[1]
be compiled with pthreads otherwise this option is ignored with a
warning. This is meant to reduce packing time on multiprocessor
machines. The required amount of memory for the delta search window
is however multiplied by the number of threads.
pack.indexVersion::
Specify the default pack index version. Valid values are 1 for
legacy pack index used by Git versions prior to 1.5.2, and 2 for
the new pack index with capabilities for packs larger than 4 GB
as well as proper protection against the repacking of corrupted
packs. Version 2 is selected and this config option ignored
whenever the corresponding pack is larger than 2 GB. Otherwise
the default is 1.
pack.packSizeLimit:
The default maximum size of a pack. This setting only affects
packing to a file, i.e. the git:// protocol is unaffected. It
can be overridden by the `\--max-pack-size` option of
linkgit:git-repack[1].
pull.octopus::
The default merge strategy to use when pulling multiple branches
at once.
pull.twohead::
The default merge strategy to use when pulling a single branch.
remote.<name>.url::
The URL of a remote repository. See linkgit:git-fetch[1] or
linkgit:git-push[1].
remote.<name>.proxy::
For remotes that require curl (http, https and ftp), the URL to
the proxy to use for that remote. Set to the empty string to
disable proxying for that remote.
remote.<name>.fetch::
The default set of "refspec" for linkgit:git-fetch[1]. See
linkgit:git-fetch[1].
remote.<name>.push::
The default set of "refspec" for linkgit:git-push[1]. See
linkgit:git-push[1].
remote.<name>.skipDefaultUpdate::
If true, this remote will be skipped by default when updating
using the update subcommand of linkgit:git-remote[1].
remote.<name>.receivepack::
The default program to execute on the remote side when pushing. See
option \--exec of linkgit:git-push[1].
remote.<name>.uploadpack::
The default program to execute on the remote side when fetching. See
option \--exec of linkgit:git-fetch-pack[1].
remote.<name>.tagopt::
Setting this value to --no-tags disables automatic tag following when fetching
from remote <name>
remotes.<group>::
The list of remotes which are fetched by "git remote update
<group>". See linkgit:git-remote[1].
repack.usedeltabaseoffset::
Allow linkgit:git-repack[1] to create packs that uses
delta-base offset. Defaults to false.
show.difftree::
The default linkgit:git-diff-tree[1] arguments to be used
for linkgit:git-show[1].
showbranch.default::
The default set of branches for linkgit:git-show-branch[1].
See linkgit:git-show-branch[1].
status.relativePaths::
By default, linkgit:git-status[1] shows paths relative to the
current directory. Setting this variable to `false` shows paths
relative to the repository root (this was the default for git
prior to v1.5.4).
tar.umask::
This variable can be used to restrict the permission bits of
tar archive entries. The default is 0002, which turns off the
world write bit. The special value "user" indicates that the
archiving user's umask will be used instead. See umask(2) and
linkgit:git-archive[1].
user.email::
Your email address to be recorded in any newly created commits.
Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
'EMAIL' environment variables. See linkgit:git-commit-tree[1].
user.name::
Your full name to be recorded in any newly created commits.
Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
environment variables. See linkgit:git-commit-tree[1].
user.signingkey::
If linkgit:git-tag[1] is not selecting the key you want it to
automatically when creating a signed tag, you can override the
default selection with this variable. This option is passed
unchanged to gpg's --local-user parameter, so you may specify a key
using any method that gpg supports.
whatchanged.difftree::
The default linkgit:git-diff-tree[1] arguments to be used
for linkgit:git-whatchanged[1].
imap::
The configuration variables in the 'imap' section are described
in linkgit:git-imap-send[1].
receive.unpackLimit::
If the number of objects received in a push is below this
limit then the objects will be unpacked into loose object
files. However if the number of received objects equals or
exceeds this limit then the received pack will be stored as
a pack, after adding any missing delta bases. Storing the
pack from a push can make the push operation complete faster,
especially on slow filesystems. If not set, the value of
`transfer.unpackLimit` is used instead.
receive.denyNonFastForwards::
If set to true, git-receive-pack will deny a ref update which is
not a fast forward. Use this to prevent such an update via a push,
even if that push is forced. This configuration variable is
set when initializing a shared repository.
transfer.unpackLimit::
When `fetch.unpackLimit` or `receive.unpackLimit` are
not set, the value of this variable is used instead.
The default value is 100.
web.browser::
Specify a web browser that may be used by some commands.
Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
may use it.
