4 The git configuration file contains a number of variables that affect
5 the git command's behavior. `.git/config` file for each repository
6 is used to store the information for that repository, and
7 `$HOME/.gitconfig` is used to store per user information to give
8 fallback values for `.git/config` file. The file `/etc/gitconfig`
9 can be used to store system-wide defaults.
11 They can be used by both the git plumbing
12 and the porcelains. The variables are divided into sections, where
13 in the fully qualified variable name the variable itself is the last
14 dot-separated segment and the section name is everything before the last
15 dot. The variable names are case-insensitive and only alphanumeric
16 characters are allowed. Some variables may appear multiple times.
21 The syntax is fairly flexible and permissive; whitespaces are mostly
22 ignored. The '#' and ';' characters begin comments to the end of line,
23 blank lines are ignored.
25 The file consists of sections and variables. A section begins with
26 the name of the section in square brackets and continues until the next
27 section begins. Section names are not case sensitive. Only alphanumeric
28 characters, '`-`' and '`.`' are allowed in section names. Each variable
29 must belong to some section, which means that there must be section
30 header before first setting of a variable.
32 Sections can be further divided into subsections. To begin a subsection
33 put its name in double quotes, separated by space from the section name,
34 in the section header, like in example below:
37 [section "subsection"]
41 Subsection names can contain any characters except newline (doublequote
42 '`"`' and backslash have to be escaped as '`\"`' and '`\\`',
43 respectively) and are case sensitive. Section header cannot span multiple
44 lines. Variables may belong directly to a section or to a given subsection.
45 You can have `[section]` if you have `[section "subsection"]`, but you
48 There is also (case insensitive) alternative `[section.subsection]` syntax.
49 In this syntax subsection names follow the same restrictions as for section
52 All the other lines are recognized as setting variables, in the form
53 'name = value'. If there is no equal sign on the line, the entire line
54 is taken as 'name' and the variable is recognized as boolean "true".
55 The variable names are case-insensitive and only alphanumeric
56 characters and '`-`' are allowed. There can be more than one value
57 for a given variable; we say then that variable is multivalued.
59 Leading and trailing whitespace in a variable value is discarded.
60 Internal whitespace within a variable value is retained verbatim.
62 The values following the equals sign in variable assign are all either
63 a string, an integer, or a boolean. Boolean values may be given as yes/no,
64 0/1 or true/false. Case is not significant in boolean values, when
65 converting value to the canonical form using '--bool' type specifier;
66 `git-config` will ensure that the output is "true" or "false".
68 String values may be entirely or partially enclosed in double quotes.
69 You need to enclose variable value in double quotes if you want to
70 preserve leading or trailing whitespace, or if variable value contains
71 beginning of comment characters (if it contains '#' or ';').
72 Double quote '`"`' and backslash '`\`' characters in variable value must
73 be escaped: use '`\"`' for '`"`' and '`\\`' for '`\`'.
75 The following escape sequences (beside '`\"`' and '`\\`') are recognized:
76 '`\n`' for newline character (NL), '`\t`' for horizontal tabulation (HT, TAB)
77 and '`\b`' for backspace (BS). No other char escape sequence, nor octal
78 char sequences are valid.
80 Variable value ending in a '`\`' is continued on the next line in the
81 customary UNIX fashion.
83 Some variables may require special value format.
90 ; Don't trust file modes
95 external = "/usr/local/bin/gnu-diff -u"
100 merge = refs/heads/devel
104 gitProxy="ssh" for "kernel.org"
105 gitProxy=default-proxy ; for the rest
110 Note that this list is non-comprehensive and not necessarily complete.
111 For command-specific variables, you will find a more detailed description
112 in the appropriate manual page. You will find a description of non-core
113 porcelain configuration variables in the respective porcelain documentation.
116 If false, the executable bit differences between the index and
117 the working copy are ignored; useful on broken filesystems like FAT.
118 See gitlink:git-update-index[1]. True by default.
121 The commands that output paths (e.g. `ls-files`,
122 `diff`), when not given the `-z` option, will quote
123 "unusual" characters in the pathname by enclosing the
124 pathname in a double-quote pair and with backslashes the
125 same way strings in C source code are quoted. If this
126 variable is set to false, the bytes higher than 0x80 are
127 not quoted but output as verbatim. Note that double
128 quote, backslash and control characters are always
129 quoted without `-z` regardless of the setting of this
133 If true, makes git convert `CRLF` at the end of lines in text files to
134 `LF` when reading from the filesystem, and convert in reverse when
135 writing to the filesystem. The variable can be set to
136 'input', in which case the conversion happens only while
137 reading from the filesystem but files are written out with
138 `LF` at the end of lines. Currently, which paths to consider
139 "text" (i.e. be subjected to the autocrlf mechanism) is
140 decided purely based on the contents.
143 If false, symbolic links are checked out as small plain files that
144 contain the link text. gitlink:git-update-index[1] and
145 gitlink:git-add[1] will not change the recorded type to regular
146 file. Useful on filesystems like FAT that do not support
147 symbolic links. True by default.
150 A "proxy command" to execute (as 'command host port') instead
151 of establishing direct connection to the remote server when
152 using the git protocol for fetching. If the variable value is
153 in the "COMMAND for DOMAIN" format, the command is applied only
154 on hostnames ending with the specified domain string. This variable
155 may be set multiple times and is matched in the given order;
156 the first match wins.
158 Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
159 (which always applies universally, without the special "for"
163 The working copy files are assumed to stay unchanged until you
164 mark them otherwise manually - Git will not detect the file changes
165 by lstat() calls. This is useful on systems where those are very
166 slow, such as Microsoft Windows. See gitlink:git-update-index[1].
169 core.preferSymlinkRefs::
170 Instead of the default "symref" format for HEAD
171 and other symbolic reference files, use symbolic links.
172 This is sometimes needed to work with old scripts that
173 expect HEAD to be a symbolic link.
176 If true this repository is assumed to be 'bare' and has no
177 working directory associated with it. If this is the case a
178 number of commands that require a working directory will be
179 disabled, such as gitlink:git-add[1] or gitlink:git-merge[1].
181 This setting is automatically guessed by gitlink:git-clone[1] or
182 gitlink:git-init[1] when the repository was created. By default a
183 repository that ends in "/.git" is assumed to be not bare (bare =
184 false), while all other repositories are assumed to be bare (bare
188 Set the path to the working tree. The value will not be
189 used in combination with repositories found automatically in
190 a .git directory (i.e. $GIT_DIR is not set).
191 This can be overriden by the GIT_WORK_TREE environment
192 variable and the '--work-tree' command line option.
194 core.logAllRefUpdates::
195 Enable the reflog. Updates to a ref <ref> is logged to the file
196 "$GIT_DIR/logs/<ref>", by appending the new and old
197 SHA1, the date/time and the reason of the update, but
198 only when the file exists. If this configuration
199 variable is set to true, missing "$GIT_DIR/logs/<ref>"
200 file is automatically created for branch heads.
202 This information can be used to determine what commit
203 was the tip of a branch "2 days ago".
205 This value is true by default in a repository that has
206 a working directory associated with it, and false by
207 default in a bare repository.
209 core.repositoryFormatVersion::
210 Internal variable identifying the repository format and layout
213 core.sharedRepository::
214 When 'group' (or 'true'), the repository is made shareable between
215 several users in a group (making sure all the files and objects are
216 group-writable). When 'all' (or 'world' or 'everybody'), the
217 repository will be readable by all users, additionally to being
218 group-shareable. When 'umask' (or 'false'), git will use permissions
219 reported by umask(2). See gitlink:git-init[1]. False by default.
221 core.warnAmbiguousRefs::
222 If true, git will warn you if the ref name you passed it is ambiguous
223 and might match multiple refs in the .git/refs/ tree. True by default.
226 An integer -1..9, indicating a default compression level.
227 -1 is the zlib default. 0 means no compression,
228 and 1..9 are various speed/size tradeoffs, 9 being slowest.
230 core.loosecompression::
231 An integer -1..9, indicating the compression level for objects that
232 are not in a pack file. -1 is the zlib default. 0 means no
233 compression, and 1..9 are various speed/size tradeoffs, 9 being
234 slowest. If not set, defaults to core.compression. If that is
235 not set, defaults to 0 (best speed).
237 core.packedGitWindowSize::
238 Number of bytes of a pack file to map into memory in a
239 single mapping operation. Larger window sizes may allow
240 your system to process a smaller number of large pack files
241 more quickly. Smaller window sizes will negatively affect
242 performance due to increased calls to the operating system's
243 memory manager, but may improve performance when accessing
244 a large number of large pack files.
246 Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
247 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should
248 be reasonable for all users/operating systems. You probably do
249 not need to adjust this value.
251 Common unit suffixes of 'k', 'm', or 'g' are supported.
253 core.packedGitLimit::
254 Maximum number of bytes to map simultaneously into memory
255 from pack files. If Git needs to access more than this many
256 bytes at once to complete an operation it will unmap existing
257 regions to reclaim virtual address space within the process.
259 Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
260 This should be reasonable for all users/operating systems, except on
261 the largest projects. You probably do not need to adjust this value.
263 Common unit suffixes of 'k', 'm', or 'g' are supported.
265 core.deltaBaseCacheLimit::
266 Maximum number of bytes to reserve for caching base objects
267 that multiple deltafied objects reference. By storing the
268 entire decompressed base objects in a cache Git is able
269 to avoid unpacking and decompressing frequently used base
270 objects multiple times.
272 Default is 16 MiB on all platforms. This should be reasonable
273 for all users/operating systems, except on the largest projects.
274 You probably do not need to adjust this value.
276 Common unit suffixes of 'k', 'm', or 'g' are supported.
279 In addition to '.gitignore' (per-directory) and
280 '.git/info/exclude', git looks into this file for patterns
281 of files which are not meant to be tracked. See
282 gitlink:gitignore[5].
285 Commands such as `commit` and `tag` that lets you edit
286 messages by lauching an editor uses the value of this
287 variable when it is set, and the environment variable
288 `GIT_EDITOR` is not set. The order of preference is
289 `GIT_EDITOR` environment, `core.editor`, `VISUAL` and
290 `EDITOR` environment variables and then finally `vi`.
293 The command that git will use to paginate output. Can be overridden
294 with the `GIT_PAGER` environment variable.
297 Command aliases for the gitlink:git[1] command wrapper - e.g.
298 after defining "alias.last = cat-file commit HEAD", the invocation
299 "git last" is equivalent to "git cat-file commit HEAD". To avoid
300 confusion and troubles with script usage, aliases that
301 hide existing git commands are ignored. Arguments are split by
302 spaces, the usual shell quoting and escaping is supported.
303 quote pair and a backslash can be used to quote them.
305 If the alias expansion is prefixed with an exclamation point,
306 it will be treated as a shell command. For example, defining
307 "alias.new = !gitk --all --not ORIG_HEAD", the invocation
308 "git new" is equivalent to running the shell command
309 "gitk --all --not ORIG_HEAD".
312 Tells `git-apply` how to handle whitespaces, in the same way
313 as the '--whitespace' option. See gitlink:git-apply[1].
315 branch.autosetupmerge::
316 Tells `git-branch` and `git-checkout` to setup new branches
317 so that gitlink:git-pull[1] will appropriately merge from that
318 remote branch. Note that even if this option is not set,
319 this behavior can be chosen per-branch using the `--track`
320 and `--no-track` options. This option defaults to false.
322 branch.<name>.remote::
323 When in branch <name>, it tells `git fetch` which remote to fetch.
324 If this option is not given, `git fetch` defaults to remote "origin".
326 branch.<name>.merge::
327 When in branch <name>, it tells `git fetch` the default refspec to
328 be marked for merging in FETCH_HEAD. The value has exactly to match
329 a remote part of one of the refspecs which are fetched from the remote
330 given by "branch.<name>.remote".
331 The merge information is used by `git pull` (which at first calls
332 `git fetch`) to lookup the default branch for merging. Without
333 this option, `git pull` defaults to merge the first refspec fetched.
334 Specify multiple values to get an octopus merge.
335 If you wish to setup `git pull` so that it merges into <name> from
336 another branch in the local repository, you can point
337 branch.<name>.merge to the desired branch, and use the special setting
338 `.` (a period) for branch.<name>.remote.
341 A boolean to make git-clean do nothing unless given -f or -n. Defaults
345 A boolean to enable/disable color in the output of
346 gitlink:git-branch[1]. May be set to `true` (or `always`),
347 `false` (or `never`) or `auto`, in which case colors are used
348 only when the output is to a terminal. Defaults to false.
350 color.branch.<slot>::
351 Use customized color for branch coloration. `<slot>` is one of
352 `current` (the current branch), `local` (a local branch),
353 `remote` (a tracking branch in refs/remotes/), `plain` (other
356 The value for these configuration variables is a list of colors (at most
357 two) and attributes (at most one), separated by spaces. The colors
358 accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
359 `magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
360 `blink` and `reverse`. The first color given is the foreground; the
361 second is the background. The position of the attribute, if any,
365 When true (or `always`), always use colors in patch.
366 When false (or `never`), never. When set to `auto`, use
367 colors only when the output is to the terminal.
370 Use customized color for diff colorization. `<slot>` specifies
371 which part of the patch to use the specified color, and is one
372 of `plain` (context text), `meta` (metainformation), `frag`
373 (hunk header), `old` (removed lines), `new` (added lines),
374 `commit` (commit headers), or `whitespace` (highlighting dubious
375 whitespace). The values of these variables may be specified as
376 in color.branch.<slot>.
379 A boolean to enable/disable colored output when the pager is in
380 use (default is true).
383 A boolean to enable/disable color in the output of
384 gitlink:git-status[1]. May be set to `true` (or `always`),
385 `false` (or `never`) or `auto`, in which case colors are used
386 only when the output is to a terminal. Defaults to false.
388 color.status.<slot>::
389 Use customized color for status colorization. `<slot>` is
390 one of `header` (the header text of the status message),
391 `added` or `updated` (files which are added but not committed),
392 `changed` (files which are changed but not added in the index),
393 or `untracked` (files which are not tracked by git). The values of
394 these variables may be specified as in color.branch.<slot>.
397 Specify a file to use as the template for new commit messages.
400 The number of files to consider when performing the copy/rename
401 detection; equivalent to the git diff option '-l'.
404 Tells git to detect renames. If set to any boolean value, it
405 will enable basic rename detection. If set to "copies" or
406 "copy", it will detect copies, as well.
409 If the number of objects fetched over the git native
410 transfer is below this
411 limit, then the objects will be unpacked into loose object
412 files. However if the number of received objects equals or
413 exceeds this limit then the received pack will be stored as
414 a pack, after adding any missing delta bases. Storing the
415 pack from a push can make the push operation complete faster,
416 especially on slow filesystems.
419 Additional email headers to include in a patch to be submitted
420 by mail. See gitlink:git-format-patch[1].
423 The default for format-patch is to output files with the suffix
424 `.patch`. Use this variable to change that suffix (make sure to
425 include the dot if you want it).
427 gc.aggressiveWindow::
428 The window size parameter used in the delta compression
429 algorithm used by 'git gc --aggressive'. This defaults
433 `git gc` does not run `git pack-refs` in a bare repository by
434 default so that older dumb-transport clients can still fetch
435 from the repository. Setting this to `true` lets `git
436 gc` to run `git pack-refs`. Setting this to `false` tells
437 `git gc` never to run `git pack-refs`. The default setting is
438 `notbare`. Enable it only when you know you do not have to
439 support such clients. The default setting will change to `true`
440 at some stage, and setting this to `false` will continue to
441 prevent `git pack-refs` from being run from `git gc`.
444 `git reflog expire` removes reflog entries older than
445 this time; defaults to 90 days.
447 gc.reflogexpireunreachable::
448 `git reflog expire` removes reflog entries older than
449 this time and are not reachable from the current tip;
453 Records of conflicted merge you resolved earlier are
454 kept for this many days when `git rerere gc` is run.
455 The default is 60 days. See gitlink:git-rerere[1].
457 gc.rerereunresolved::
458 Records of conflicted merge you have not resolved are
459 kept for this many days when `git rerere gc` is run.
460 The default is 15 days. See gitlink:git-rerere[1].
463 Activate recording of resolved conflicts, so that identical
464 conflict hunks can be resolved automatically, should they
465 be encountered again. See gitlink:git-rerere[1].
468 Whether the cvs server interface is enabled for this repository.
469 See gitlink:git-cvsserver[1].
472 Path to a log file where the cvs server interface well... logs
473 various stuff. See gitlink:git-cvsserver[1].
476 If true, all files are sent to the client in mode '-kb'. This
477 causes the client to treat all files as binary files which suppresses
478 any newline munging it otherwise might do. A work-around for the
479 fact that there is no way yet to set single files to mode '-kb'.
482 Database used by git-cvsserver to cache revision information
483 derived from the git repository. The exact meaning depends on the
484 used database driver, for SQLite (which is the default driver) this
485 is a filename. Supports variable substitution (see
486 gitlink:git-cvsserver[1] for details). May not contain semicolons (`;`).
487 Default: '%Ggitcvs.%m.sqlite'
490 Used Perl DBI driver. You can specify any available driver
491 for this here, but it might not work. git-cvsserver is tested
492 with 'DBD::SQLite', reported to work with 'DBD::Pg', and
493 reported *not* to work with 'DBD::mysql'. Experimental feature.
494 May not contain double colons (`:`). Default: 'SQLite'.
495 See gitlink:git-cvsserver[1].
497 gitcvs.dbuser, gitcvs.dbpass::
498 Database user and password. Only useful if setting 'gitcvs.dbdriver',
499 since SQLite has no concept of database users and/or passwords.
500 'gitcvs.dbuser' supports variable substitution (see
501 gitlink:git-cvsserver[1] for details).
503 All gitcvs variables except for 'gitcvs.allbinary' can also specifed
504 as 'gitcvs.<access_method>.<varname>' (where 'access_method' is one
505 of "ext" and "pserver") to make them apply only for the given access
509 Whether to verify the SSL certificate when fetching or pushing
510 over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
514 File containing the SSL certificate when fetching or pushing
515 over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
519 File containing the SSL private key when fetching or pushing
520 over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
524 File containing the certificates to verify the peer with when
525 fetching or pushing over HTTPS. Can be overridden by the
526 'GIT_SSL_CAINFO' environment variable.
529 Path containing files with the CA certificates to verify the peer
530 with when fetching or pushing over HTTPS. Can be overridden
531 by the 'GIT_SSL_CAPATH' environment variable.
534 How many HTTP requests to launch in parallel. Can be overridden
535 by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
537 http.lowSpeedLimit, http.lowSpeedTime::
538 If the HTTP transfer speed is less than 'http.lowSpeedLimit'
539 for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
540 Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
541 'GIT_HTTP_LOW_SPEED_TIME' environment variables.
544 A boolean which disables using of EPSV ftp command by curl.
545 This can helpful with some "poor" ftp servers which don't
546 support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
547 environment variable. Default is false (curl will use EPSV).
549 i18n.commitEncoding::
550 Character encoding the commit messages are stored in; git itself
551 does not care per se, but this information is necessary e.g. when
552 importing commits from emails or in the gitk graphical history
553 browser (and possibly at other places in the future or in other
554 porcelains). See e.g. gitlink:git-mailinfo[1]. Defaults to 'utf-8'.
556 i18n.logOutputEncoding::
557 Character encoding the commit messages are converted to when
558 running `git-log` and friends.
561 If true, the initial commit will be shown as a big creation event.
562 This is equivalent to a diff against an empty tree.
563 Tools like gitlink:git-log[1] or gitlink:git-whatchanged[1], which
564 normally hide the root commit will now show it. True by default.
567 Whether to include summaries of merged commits in newly created
568 merge commit messages. False by default.
571 Controls which merge resolution program is used by
572 gitlink:git-mergetool[l]. Valid values are: "kdiff3", "tkdiff",
573 "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", and "opendiff".
576 Controls the amount of output shown by the recursive merge
577 strategy. Level 0 outputs nothing except a final error
578 message if conflicts were detected. Level 1 outputs only
579 conflicts, 2 outputs conflicts and file changes. Level 5 and
580 above outputs debugging information. The default is level 2.
581 Can be overriden by 'GIT_MERGE_VERBOSITY' environment variable.
583 merge.<driver>.name::
584 Defines a human readable name for a custom low-level
585 merge driver. See gitlink:gitattributes[5] for details.
587 merge.<driver>.driver::
588 Defines the command that implements a custom low-level
589 merge driver. See gitlink:gitattributes[5] for details.
591 merge.<driver>.recursive::
592 Names a low-level merge driver to be used when
593 performing an internal merge between common ancestors.
594 See gitlink:gitattributes[5] for details.
597 The size of the window used by gitlink:git-pack-objects[1] when no
598 window size is given on the command line. Defaults to 10.
601 The maximum delta depth used by gitlink:git-pack-objects[1] when no
602 maximum depth is given on the command line. Defaults to 50.
605 The window memory size limit used by gitlink:git-pack-objects[1]
606 when no limit is given on the command line. The value can be
607 suffixed with "k", "m", or "g". Defaults to 0, meaning no
611 An integer -1..9, indicating the compression level for objects
612 in a pack file. -1 is the zlib default. 0 means no
613 compression, and 1..9 are various speed/size tradeoffs, 9 being
614 slowest. If not set, defaults to core.compression. If that is
615 not set, defaults to -1.
617 pack.deltaCacheSize::
618 The maxium memory in bytes used for caching deltas in
619 gitlink:git-pack-objects[1].
620 A value of 0 means no limit. Defaults to 0.
622 pack.deltaCacheLimit::
623 The maxium size of a delta, that is cached in
624 gitlink:git-pack-objects[1]. Defaults to 1000.
627 The default merge strategy to use when pulling multiple branches
631 The default merge strategy to use when pulling a single branch.
634 The URL of a remote repository. See gitlink:git-fetch[1] or
637 remote.<name>.fetch::
638 The default set of "refspec" for gitlink:git-fetch[1]. See
639 gitlink:git-fetch[1].
642 The default set of "refspec" for gitlink:git-push[1]. See
645 remote.<name>.skipDefaultUpdate::
646 If true, this remote will be skipped by default when updating
647 using the remote subcommand of gitlink:git-remote[1].
649 remote.<name>.receivepack::
650 The default program to execute on the remote side when pushing. See
651 option \--exec of gitlink:git-push[1].
653 remote.<name>.uploadpack::
654 The default program to execute on the remote side when fetching. See
655 option \--exec of gitlink:git-fetch-pack[1].
657 remote.<name>.tagopt::
658 Setting this value to --no-tags disables automatic tag following when fetching
662 The list of remotes which are fetched by "git remote update
663 <group>". See gitlink:git-remote[1].
665 repack.usedeltabaseoffset::
666 Allow gitlink:git-repack[1] to create packs that uses
667 delta-base offset. Defaults to false.
670 The default gitlink:git-diff-tree[1] arguments to be used
671 for gitlink:git-show[1].
674 The default set of branches for gitlink:git-show-branch[1].
675 See gitlink:git-show-branch[1].
678 By default, gitlink:git-tar-tree[1] sets file and directories modes
679 to 0666 or 0777. While this is both useful and acceptable for projects
680 such as the Linux Kernel, it might be excessive for other projects.
681 With this variable, it becomes possible to tell
682 gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
683 The special value "user" indicates that the user's current umask will
684 be used. This should be enough for most projects, as it will lead to
685 the same permissions as gitlink:git-checkout[1] would use. The default
686 value remains 0, which means world read-write.
689 Your email address to be recorded in any newly created commits.
690 Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
691 'EMAIL' environment variables. See gitlink:git-commit-tree[1].
694 Your full name to be recorded in any newly created commits.
695 Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
696 environment variables. See gitlink:git-commit-tree[1].
699 If gitlink:git-tag[1] is not selecting the key you want it to
700 automatically when creating a signed tag, you can override the
701 default selection with this variable. This option is passed
702 unchanged to gpg's --local-user parameter, so you may specify a key
703 using any method that gpg supports.
705 whatchanged.difftree::
706 The default gitlink:git-diff-tree[1] arguments to be used
707 for gitlink:git-whatchanged[1].
710 The configuration variables in the 'imap' section are described
711 in gitlink:git-imap-send[1].
713 receive.unpackLimit::
714 If the number of objects received in a push is below this
715 limit then the objects will be unpacked into loose object
716 files. However if the number of received objects equals or
717 exceeds this limit then the received pack will be stored as
718 a pack, after adding any missing delta bases. Storing the
719 pack from a push can make the push operation complete faster,
720 especially on slow filesystems.
722 receive.denyNonFastForwards::
723 If set to true, git-receive-pack will deny a ref update which is
724 not a fast forward. Use this to prevent such an update via a push,
725 even if that push is forced. This configuration variable is
726 set when initializing a shared repository.
728 transfer.unpackLimit::
729 When `fetch.unpackLimit` or `receive.unpackLimit` are
730 not set, the value of this variable is used instead.
