Merge branch 'maint'

1 CONFIGURATION FILE
2 ------------------
3
4 The git configuration file contains a number of variables that affect
5 the git command's behavior. They can be used by both the git plumbing
6 and the porcelains. The variables are divided into sections, where
7 in the fully qualified variable name the variable itself is the last
8 dot-separated segment and the section name is everything before the last
9 dot. The variable names are case-insensitive and only alphanumeric
10 characters are allowed. Some variables may appear multiple times.
11
12 The syntax is fairly flexible and permissive; whitespaces are mostly
13 ignored. The '#' and ';' characters begin comments to the end of line,
14 blank lines are ignored, lines containing strings enclosed in square
15 brackets start sections and all the other lines are recognized
16 as setting variables, in the form 'name = value'. If there is no equal
17 sign on the line, the entire line is taken as 'name' and the variable
18 is recognized as boolean "true". String values may be entirely or partially
19 enclosed in double quotes; some variables may require special value format.

39 Variables
40 ~~~~~~~~~
41
42 Note that this list is non-comprehensive and not necessarily complete.
43 For command-specific variables, you will find a more detailed description
44 in the appropriate manual page. You will find a description of non-core
45 porcelain configuration variables in the respective porcelain documentation.
46
47 core.fileMode::
48 If false, the executable bit differences between the index and
49 the working copy are ignored; useful on broken filesystems like FAT.
50 See gitlink:git-update-index[1]. True by default.
51
52 core.gitProxy::
53 A "proxy command" to execute (as 'command host port') instead
54 of establishing direct connection to the remote server when
55 using the git protocol for fetching. If the variable value is
56 in the "COMMAND for DOMAIN" format, the command is applied only
57 on hostnames ending with the specified domain string. This variable
58 may be set multiple times and is matched in the given order;
59 the first match wins.
60 +
61 Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
62 (which always applies universally, without the special "for"
63 handling).
64
65 core.ignoreStat::
66 The working copy files are assumed to stay unchanged until you
67 mark them otherwise manually - Git will not detect the file changes
68 by lstat() calls. This is useful on systems where those are very
69 slow, such as Microsoft Windows. See gitlink:git-update-index[1].
70 False by default.
71
72 core.preferSymlinkRefs::
73 Instead of the default "symref" format for HEAD
74 and other symbolic reference files, use symbolic links.
75 This is sometimes needed to work with old scripts that
76 expect HEAD to be a symbolic link.
77
78 core.logAllRefUpdates::
79 Updates to a ref <ref> is logged to the file
80 "$GIT_DIR/logs/<ref>", by appending the new and old
81 SHA1, the date/time and the reason of the update, but
82 only when the file exists. If this configuration
83 variable is set to true, missing "$GIT_DIR/logs/<ref>"
84 file is automatically created for branch heads.
85
86 This information can be used to determine what commit
87 was the tip of a branch "2 days ago".
88
89 This value is true by default in a repository that has
90 a working directory associated with it, and false by
91 default in a bare repository.
92
93 core.repositoryFormatVersion::
94 Internal variable identifying the repository format and layout
95 version.
96
97 core.sharedRepository::
98 When 'group' (or 'true'), the repository is made shareable between
99 several users in a group (making sure all the files and objects are
100 group-writable). When 'all' (or 'world' or 'everybody'), the
101 repository will be readable by all users, additionally to being
102 group-shareable. When 'umask' (or 'false'), git will use permissions
103 reported by umask(2). See gitlink:git-init-db[1]. False by default.
104
105 core.warnAmbiguousRefs::
106 If true, git will warn you if the ref name you passed it is ambiguous
107 and might match multiple refs in the .git/refs/ tree. True by default.
108
109 core.compression::
110 An integer -1..9, indicating the compression level for objects that
111 are not in a pack file. -1 is the zlib and git default. 0 means no
112 compression, and 1..9 are various speed/size tradeoffs, 9 being
113 slowest.
114
115 core.legacyheaders::
116 A boolean which enables the legacy object header format in case
117 you want to interoperate with old clients accessing the object
118 database directly (where the "http://" and "rsync://" protocols
119 count as direct access).
120
121 alias.*::
122 Command aliases for the gitlink:git[1] command wrapper - e.g.
123 after defining "alias.last = cat-file commit HEAD", the invocation
124 "git last" is equivalent to "git cat-file commit HEAD". To avoid
125 confusion and troubles with script usage, aliases that
126 hide existing git commands are ignored. Arguments are split by
127 spaces, the usual shell quoting and escaping is supported.
128 quote pair and a backslash can be used to quote them.
129
130 apply.whitespace::
131 Tells `git-apply` how to handle whitespaces, in the same way
132 as the '--whitespace' option. See gitlink:git-apply[1].
133
134 branch.<name>.remote::
135 When in branch <name>, it tells `git fetch` which remote to fetch.
136 If this option is not given, `git fetch` defaults to remote "origin".
137
138 branch.<name>.merge::
139 When in branch <name>, it tells `git fetch` the default refspec to
140 be marked for merging in FETCH_HEAD. The value has exactly to match
141 a remote part of one of the refspecs which are fetched from the remote
142 given by "branch.<name>.remote".
143 The merge information is used by `git pull` (which at first calls
144 `git fetch`) to lookup the default branch for merging. Without
145 this option, `git pull` defaults to merge the first refspec fetched.
146 Specify multiple values to get an octopus merge.
147
148 color.diff::
149 When true (or `always`), always use colors in patch.
150 When false (or `never`), never. When set to `auto`, use
151 colors only when the output is to the terminal.
152
153 color.diff.<slot>::
154 Use customized color for diff colorization. `<slot>`
155 specifies which part of the patch to use the specified
156 color, and is one of `plain` (context text), `meta`
157 (metainformation), `frag` (hunk header), `old` (removed
158 lines), or `new` (added lines). The value for these
159 configuration variables can be one of: `normal`, `bold`,
160 `dim`, `ul`, `blink`, `reverse`, `reset`, `black`,
161 `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, or
162 `white`.
163
164 color.pager::
165 A boolean to enable/disable colored output when the pager is in
166 use (default is true).
167
168 color.status::
169 A boolean to enable/disable color in the output of
170 gitlink:git-status[1]. May be set to `true` (or `always`),
171 `false` (or `never`) or `auto`, in which case colors are used
172 only when the output is to a terminal. Defaults to false.
173
174 color.status.<slot>::
175 Use customized color for status colorization. `<slot>` is
176 one of `header` (the header text of the status message),
177 `added` or `updated` (files which are added but not committed),
178 `changed` (files which are changed but not added in the index),
179 or `untracked` (files which are not tracked by git). The values of
180 these variables may be specified as in color.diff.<slot>.
181
182 diff.renameLimit::
183 The number of files to consider when performing the copy/rename
184 detection; equivalent to the git diff option '-l'.
185
186 diff.renames::
187 Tells git to detect renames. If set to any boolean value, it
188 will enable basic rename detection. If set to "copies" or
189 "copy", it will detect copies, as well.
190
191 format.headers::
192 Additional email headers to include in a patch to be submitted
193 by mail. See gitlink:git-format-patch[1].
194
195 gitcvs.enabled::
196 Whether the cvs pserver interface is enabled for this repository.
197 See gitlink:git-cvsserver[1].
198
199 gitcvs.logfile::
200 Path to a log file where the cvs pserver interface well... logs
201 various stuff. See gitlink:git-cvsserver[1].
202
203 http.sslVerify::
204 Whether to verify the SSL certificate when fetching or pushing
205 over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
206 variable.
207
208 http.sslCert::
209 File containing the SSL certificate when fetching or pushing
210 over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
211 variable.
212
213 http.sslKey::
214 File containing the SSL private key when fetching or pushing
215 over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
216 variable.
217
218 http.sslCAInfo::
219 File containing the certificates to verify the peer with when
220 fetching or pushing over HTTPS. Can be overridden by the
221 'GIT_SSL_CAINFO' environment variable.
222
223 http.sslCAPath::
224 Path containing files with the CA certificates to verify the peer
225 with when fetching or pushing over HTTPS. Can be overridden
226 by the 'GIT_SSL_CAPATH' environment variable.
227
228 http.maxRequests::
229 How many HTTP requests to launch in parallel. Can be overridden
230 by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
231
232 http.lowSpeedLimit, http.lowSpeedTime::
233 If the HTTP transfer speed is less than 'http.lowSpeedLimit'
234 for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
235 Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
236 'GIT_HTTP_LOW_SPEED_TIME' environment variables.
237
238 http.noEPSV::
239 A boolean which disables using of EPSV ftp command by curl.
240 This can helpful with some "poor" ftp servers which doesn't
241 support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
242 environment variable. Default is false (curl will use EPSV).
243
244 i18n.commitEncoding::
245 Character encoding the commit messages are stored in; git itself
246 does not care per se, but this information is necessary e.g. when
247 importing commits from emails or in the gitk graphical history
248 browser (and possibly at other places in the future or in other
249 porcelains). See e.g. gitlink:git-mailinfo[1]. Defaults to 'utf-8'.
250
251 log.showroot::
252 If true, the initial commit will be shown as a big creation event.
253 This is equivalent to a diff against an empty tree.
254 Tools like gitlink:git-log[1] or gitlink:git-whatchanged[1], which
255 normally hide the root commit will now show it. True by default.
256
257 merge.summary::
258 Whether to include summaries of merged commits in newly created
259 merge commit messages. False by default.
260
261 pack.window::
262 The size of the window used by gitlink:git-pack-objects[1] when no
263 window size is given on the command line. Defaults to 10.
264
265 pull.octopus::
266 The default merge strategy to use when pulling multiple branches
267 at once.
268
269 pull.twohead::
270 The default merge strategy to use when pulling a single branch.
271
272 remote.<name>.url::
273 The URL of a remote repository. See gitlink:git-fetch[1] or
274 gitlink:git-push[1].
275
276 remote.<name>.fetch::
277 The default set of "refspec" for gitlink:git-fetch[1]. See
278 gitlink:git-fetch[1].
279
280 remote.<name>.push::
281 The default set of "refspec" for gitlink:git-push[1]. See
282 gitlink:git-push[1].
283
284 repack.usedeltabaseoffset::
285 Allow gitlink:git-repack[1] to create packs that uses
286 delta-base offset. Defaults to false.
287
288 show.difftree::
289 The default gitlink:git-diff-tree[1] arguments to be used
290 for gitlink:git-show[1].
291
292 showbranch.default::
293 The default set of branches for gitlink:git-show-branch[1].
294 See gitlink:git-show-branch[1].
295
296 tar.umask::
297 By default, gitlink:git-tar-tree[1] sets file and directories modes
298 to 0666 or 0777. While this is both useful and acceptable for projects
299 such as the Linux Kernel, it might be excessive for other projects.
300 With this variable, it becomes possible to tell
301 gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
302 The special value "user" indicates that the user's current umask will
303 be used. This should be enough for most projects, as it will lead to
304 the same permissions as gitlink:git-checkout[1] would use. The default
305 value remains 0, which means world read-write.
306
307 user.email::
308 Your email address to be recorded in any newly created commits.
309 Can be overridden by the 'GIT_AUTHOR_EMAIL' and 'GIT_COMMITTER_EMAIL'
310 environment variables. See gitlink:git-commit-tree[1].
311
312 user.name::
313 Your full name to be recorded in any newly created commits.
314 Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
315 environment variables. See gitlink:git-commit-tree[1].
316
317 whatchanged.difftree::
318 The default gitlink:git-diff-tree[1] arguments to be used
319 for gitlink:git-whatchanged[1].
320
321 imap::
322 The configuration variables in the 'imap' section are described
323 in gitlink:git-imap-send[1].
324
325 receive.unpackLimit::
326 If the number of objects received in a push is below this
327 limit then the objects will be unpacked into loose object
328 files. However if the number of received objects equals or
329 exceeds this limit then the received pack will be stored as
330 a pack, after adding any missing delta bases. Storing the
331 pack from a push can make the push operation complete faster,
332 especially on slow filesystems.
333
334 receive.denyNonFastForwards::
335 If set to true, git-receive-pack will deny a ref update which is
336 not a fast forward. Use this to prevent such an update via a push,
337 even if that push is forced. This configuration variable is
338 set when initializing a shared repository.
339
