Make git-add behave more sensibly in a case-insensitive environment
[git/git.git] / Documentation / config.txt
1 CONFIGURATION FILE
2 ------------------
3
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.
10
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.
17
18 Syntax
19 ~~~~~~
20
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.
24
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.
31
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:
35
36 --------
37 [section "subsection"]
38
39 --------
40
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
46 don't need to.
47
48 There is also (case insensitive) alternative `[section.subsection]` syntax.
49 In this syntax subsection names follow the same restrictions as for section
50 name.
51
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.
58
59 Leading and trailing whitespace in a variable value is discarded.
60 Internal whitespace within a variable value is retained verbatim.
61
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".
67
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 '`\`'.
74
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.
79
80 Variable value ending in a '`\`' is continued on the next line in the
81 customary UNIX fashion.
82
83 Some variables may require special value format.

106
107 Variables
108 ~~~~~~~~~
109
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.
114
115 core.fileMode::
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 linkgit:git-update-index[1]. True by default.
119
120 core.quotepath::
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
130 variable.
131
132 core.autocrlf::
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.
141
142 core.safecrlf::
143 If true, makes git check if converting `CRLF` as controlled by
144 `core.autocrlf` is reversible. Git will verify if a command
145 modifies a file in the work tree either directly or indirectly.
146 For example, committing a file followed by checking out the
147 same file should yield the original file in the work tree. If
148 this is not the case for the current setting of
149 `core.autocrlf`, git will reject the file. The variable can
150 be set to "warn", in which case git will only warn about an
151 irreversible conversion but continue the operation.
152 +
153 CRLF conversion bears a slight chance of corrupting data.
154 autocrlf=true will convert CRLF to LF during commit and LF to
155 CRLF during checkout. A file that contains a mixture of LF and
156 CRLF before the commit cannot be recreated by git. For text
157 files this is the right thing to do: it corrects line endings
158 such that we have only LF line endings in the repository.
159 But for binary files that are accidentally classified as text the
160 conversion can corrupt data.
161 +
162 If you recognize such corruption early you can easily fix it by
163 setting the conversion type explicitly in .gitattributes. Right
164 after committing you still have the original file in your work
165 tree and this file is not yet corrupted. You can explicitly tell
166 git that this file is binary and git will handle the file
167 appropriately.
168 +
169 Unfortunately, the desired effect of cleaning up text files with
170 mixed line endings and the undesired effect of corrupting binary
171 files cannot be distinguished. In both cases CRLFs are removed
172 in an irreversible way. For text files this is the right thing
173 to do because CRLFs are line endings, while for binary files
174 converting CRLFs corrupts data.
175 +
176 Note, this safety check does not mean that a checkout will generate a
177 file identical to the original file for a different setting of
178 `core.autocrlf`, but only for the current one. For example, a text
179 file with `LF` would be accepted with `core.autocrlf=input` and could
180 later be checked out with `core.autocrlf=true`, in which case the
181 resulting file would contain `CRLF`, although the original file
182 contained `LF`. However, in both work trees the line endings would be
183 consistent, that is either all `LF` or all `CRLF`, but never mixed. A
184 file with mixed line endings would be reported by the `core.safecrlf`
185 mechanism.
186
187 core.symlinks::
188 If false, symbolic links are checked out as small plain files that
189 contain the link text. linkgit:git-update-index[1] and
190 linkgit:git-add[1] will not change the recorded type to regular
191 file. Useful on filesystems like FAT that do not support
192 symbolic links. True by default.
193
194 core.gitProxy::
195 A "proxy command" to execute (as 'command host port') instead
196 of establishing direct connection to the remote server when
197 using the git protocol for fetching. If the variable value is
198 in the "COMMAND for DOMAIN" format, the command is applied only
199 on hostnames ending with the specified domain string. This variable
200 may be set multiple times and is matched in the given order;
201 the first match wins.
202 +
203 Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
204 (which always applies universally, without the special "for"
205 handling).
206
207 core.ignoreStat::
208 The working copy files are assumed to stay unchanged until you
209 mark them otherwise manually - Git will not detect the file changes
210 by lstat() calls. This is useful on systems where those are very
211 slow, such as Microsoft Windows. See linkgit:git-update-index[1].
212 False by default.
213
214 core.preferSymlinkRefs::
215 Instead of the default "symref" format for HEAD
216 and other symbolic reference files, use symbolic links.
217 This is sometimes needed to work with old scripts that
218 expect HEAD to be a symbolic link.
219
220 core.bare::
221 If true this repository is assumed to be 'bare' and has no
222 working directory associated with it. If this is the case a
223 number of commands that require a working directory will be
224 disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
225 +
226 This setting is automatically guessed by linkgit:git-clone[1] or
227 linkgit:git-init[1] when the repository was created. By default a
228 repository that ends in "/.git" is assumed to be not bare (bare =
229 false), while all other repositories are assumed to be bare (bare
230 = true).
231
232 core.worktree::
233 Set the path to the working tree. The value will not be
234 used in combination with repositories found automatically in
235 a .git directory (i.e. $GIT_DIR is not set).
236 This can be overridden by the GIT_WORK_TREE environment
237 variable and the '--work-tree' command line option.
238
239 core.logAllRefUpdates::
240 Enable the reflog. Updates to a ref <ref> is logged to the file
241 "$GIT_DIR/logs/<ref>", by appending the new and old
242 SHA1, the date/time and the reason of the update, but
243 only when the file exists. If this configuration
244 variable is set to true, missing "$GIT_DIR/logs/<ref>"
245 file is automatically created for branch heads.
246 +
247 This information can be used to determine what commit
248 was the tip of a branch "2 days ago".
249 +
250 This value is true by default in a repository that has
251 a working directory associated with it, and false by
252 default in a bare repository.
253
254 core.repositoryFormatVersion::
255 Internal variable identifying the repository format and layout
256 version.
257
258 core.sharedRepository::
259 When 'group' (or 'true'), the repository is made shareable between
260 several users in a group (making sure all the files and objects are
261 group-writable). When 'all' (or 'world' or 'everybody'), the
262 repository will be readable by all users, additionally to being
263 group-shareable. When 'umask' (or 'false'), git will use permissions
264 reported by umask(2). See linkgit:git-init[1]. False by default.
265
266 core.warnAmbiguousRefs::
267 If true, git will warn you if the ref name you passed it is ambiguous
268 and might match multiple refs in the .git/refs/ tree. True by default.
269
270 core.compression::
271 An integer -1..9, indicating a default compression level.
272 -1 is the zlib default. 0 means no compression,
273 and 1..9 are various speed/size tradeoffs, 9 being slowest.
274 If set, this provides a default to other compression variables,
275 such as 'core.loosecompression' and 'pack.compression'.
276
277 core.loosecompression::
278 An integer -1..9, indicating the compression level for objects that
279 are not in a pack file. -1 is the zlib default. 0 means no
280 compression, and 1..9 are various speed/size tradeoffs, 9 being
281 slowest. If not set, defaults to core.compression. If that is
282 not set, defaults to 1 (best speed).
283
284 core.packedGitWindowSize::
285 Number of bytes of a pack file to map into memory in a
286 single mapping operation. Larger window sizes may allow
287 your system to process a smaller number of large pack files
288 more quickly. Smaller window sizes will negatively affect
289 performance due to increased calls to the operating system's
290 memory manager, but may improve performance when accessing
291 a large number of large pack files.
292 +
293 Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
294 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should
295 be reasonable for all users/operating systems. You probably do
296 not need to adjust this value.
297 +
298 Common unit suffixes of 'k', 'm', or 'g' are supported.
299
300 core.packedGitLimit::
301 Maximum number of bytes to map simultaneously into memory
302 from pack files. If Git needs to access more than this many
303 bytes at once to complete an operation it will unmap existing
304 regions to reclaim virtual address space within the process.
305 +
306 Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
307 This should be reasonable for all users/operating systems, except on
308 the largest projects. You probably do not need to adjust this value.
309 +
310 Common unit suffixes of 'k', 'm', or 'g' are supported.
311
312 core.deltaBaseCacheLimit::
313 Maximum number of bytes to reserve for caching base objects
314 that multiple deltafied objects reference. By storing the
315 entire decompressed base objects in a cache Git is able
316 to avoid unpacking and decompressing frequently used base
317 objects multiple times.
318 +
319 Default is 16 MiB on all platforms. This should be reasonable
320 for all users/operating systems, except on the largest projects.
321 You probably do not need to adjust this value.
322 +
323 Common unit suffixes of 'k', 'm', or 'g' are supported.
324
325 core.excludesfile::
326 In addition to '.gitignore' (per-directory) and
327 '.git/info/exclude', git looks into this file for patterns
328 of files which are not meant to be tracked. See
329 linkgit:gitignore[5].
330
331 core.editor::
332 Commands such as `commit` and `tag` that lets you edit
333 messages by launching an editor uses the value of this
334 variable when it is set, and the environment variable
335 `GIT_EDITOR` is not set. The order of preference is
336 `GIT_EDITOR` environment, `core.editor`, `VISUAL` and
337 `EDITOR` environment variables and then finally `vi`.
338
339 core.pager::
340 The command that git will use to paginate output. Can be overridden
341 with the `GIT_PAGER` environment variable.
342
343 core.whitespace::
344 A comma separated list of common whitespace problems to
345 notice. `git diff` will use `color.diff.whitespace` to
346 highlight them, and `git apply --whitespace=error` will
347 consider them as errors:
348 +
349 * `trailing-space` treats trailing whitespaces at the end of the line
350 as an error (enabled by default).
351 * `space-before-tab` treats a space character that appears immediately
352 before a tab character in the initial indent part of the line as an
353 error (enabled by default).
354 * `indent-with-non-tab` treats a line that is indented with 8 or more
355 space characters as an error (not enabled by default).
356 * `cr-at-eol` treats a carriage-return at the end of line as
357 part of the line terminator, i.e. with it, `trailing-space`
358 does not trigger if the character before such a carriage-return
359 is not a whitespace (not enabled by default).
360
361 alias.*::
362 Command aliases for the linkgit:git[1] command wrapper - e.g.
363 after defining "alias.last = cat-file commit HEAD", the invocation
364 "git last" is equivalent to "git cat-file commit HEAD". To avoid
365 confusion and troubles with script usage, aliases that
366 hide existing git commands are ignored. Arguments are split by
367 spaces, the usual shell quoting and escaping is supported.
368 quote pair and a backslash can be used to quote them.
369 +
370 If the alias expansion is prefixed with an exclamation point,
371 it will be treated as a shell command. For example, defining
372 "alias.new = !gitk --all --not ORIG_HEAD", the invocation
373 "git new" is equivalent to running the shell command
374 "gitk --all --not ORIG_HEAD".
375
376 apply.whitespace::
377 Tells `git-apply` how to handle whitespaces, in the same way
378 as the '--whitespace' option. See linkgit:git-apply[1].
379
380 branch.autosetupmerge::
381 Tells `git-branch` and `git-checkout` to setup new branches
382 so that linkgit:git-pull[1] will appropriately merge from the
383 starting point branch. Note that even if this option is not set,
384 this behavior can be chosen per-branch using the `--track`
385 and `--no-track` options. The valid settings are: `false` -- no
386 automatic setup is done; `true` -- automatic setup is done when the
387 starting point is a remote branch; `always` -- automatic setup is
388 done when the starting point is either a local branch or remote
389 branch. This option defaults to true.
390
391 branch.<name>.remote::
392 When in branch <name>, it tells `git fetch` which remote to fetch.
393 If this option is not given, `git fetch` defaults to remote "origin".
394
395 branch.<name>.merge::
396 When in branch <name>, it tells `git fetch` the default
397 refspec to be marked for merging in FETCH_HEAD. The value is
398 handled like the remote part of a refspec, and must match a
399 ref which is fetched from the remote given by
400 "branch.<name>.remote".
401 The merge information is used by `git pull` (which at first calls
402 `git fetch`) to lookup the default branch for merging. Without
403 this option, `git pull` defaults to merge the first refspec fetched.
404 Specify multiple values to get an octopus merge.
405 If you wish to setup `git pull` so that it merges into <name> from
406 another branch in the local repository, you can point
407 branch.<name>.merge to the desired branch, and use the special setting
408 `.` (a period) for branch.<name>.remote.
409
410 branch.<name>.mergeoptions::
411 Sets default options for merging into branch <name>. The syntax and
412 supported options are equal to that of linkgit:git-merge[1], but
413 option values containing whitespace characters are currently not
414 supported.
415
416 branch.<name>.rebase::
417 When true, rebase the branch <name> on top of the fetched branch,
418 instead of merging the default branch from the default remote.
419 *NOTE*: this is a possibly dangerous operation; do *not* use
420 it unless you understand the implications (see linkgit:git-rebase[1]
421 for details).
422
423 browser.<tool>.cmd::
424 Specify the command to invoke the specified browser. The
425 specified command is evaluated in shell with the URLs passed
426 as arguments. (See linkgit:git-web--browse[1].)
427
428 browser.<tool>.path::
429 Override the path for the given tool that may be used to
430 browse HTML help (see '-w' option in linkgit:git-help[1]) or a
431 working repository in gitweb (see linkgit:git-instaweb[1]).
432
433 clean.requireForce::
434 A boolean to make git-clean do nothing unless given -f
435 or -n. Defaults to true.
436
437 color.branch::
438 A boolean to enable/disable color in the output of
439 linkgit:git-branch[1]. May be set to `always`,
440 `false` (or `never`) or `auto` (or `true`), in which case colors are used
441 only when the output is to a terminal. Defaults to false.
442
443 color.branch.<slot>::
444 Use customized color for branch coloration. `<slot>` is one of
445 `current` (the current branch), `local` (a local branch),
446 `remote` (a tracking branch in refs/remotes/), `plain` (other
447 refs).
448 +
449 The value for these configuration variables is a list of colors (at most
450 two) and attributes (at most one), separated by spaces. The colors
451 accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
452 `magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
453 `blink` and `reverse`. The first color given is the foreground; the
454 second is the background. The position of the attribute, if any,
455 doesn't matter.
456
457 color.diff::
458 When set to `always`, always use colors in patch.
459 When false (or `never`), never. When set to `true` or `auto`, use
460 colors only when the output is to the terminal. Defaults to false.
461
462 color.diff.<slot>::
463 Use customized color for diff colorization. `<slot>` specifies
464 which part of the patch to use the specified color, and is one
465 of `plain` (context text), `meta` (metainformation), `frag`
466 (hunk header), `old` (removed lines), `new` (added lines),
467 `commit` (commit headers), or `whitespace` (highlighting
468 whitespace errors). The values of these variables may be specified as
469 in color.branch.<slot>.
470
471 color.interactive::
472 When set to `always`, always use colors for interactive prompts
473 and displays (such as those used by "git add --interactive").
474 When false (or `never`), never. When set to `true` or `auto`, use
475 colors only when the output is to the terminal. Defaults to false.
476
477 color.interactive.<slot>::
478 Use customized color for `git add --interactive`
479 output. `<slot>` may be `prompt`, `header`, or `help`, for
480 three distinct types of normal output from interactive
481 programs. The values of these variables may be specified as
482 in color.branch.<slot>.
483
484 color.pager::
485 A boolean to enable/disable colored output when the pager is in
486 use (default is true).
487
488 color.status::
489 A boolean to enable/disable color in the output of
490 linkgit:git-status[1]. May be set to `always`,
491 `false` (or `never`) or `auto` (or `true`), in which case colors are used
492 only when the output is to a terminal. Defaults to false.
493
494 color.status.<slot>::
495 Use customized color for status colorization. `<slot>` is
496 one of `header` (the header text of the status message),
497 `added` or `updated` (files which are added but not committed),
498 `changed` (files which are changed but not added in the index),
499 or `untracked` (files which are not tracked by git). The values of
500 these variables may be specified as in color.branch.<slot>.
501
502 commit.template::
503 Specify a file to use as the template for new commit messages.
504
505 color.ui::
506 When set to `always`, always use colors in all git commands which
507 are capable of colored output. When false (or `never`), never. When
508 set to `true` or `auto`, use colors only when the output is to the
509 terminal. When more specific variables of color.* are set, they always
510 take precedence over this setting. Defaults to false.
511
512 diff.autorefreshindex::
513 When using `git diff` to compare with work tree
514 files, do not consider stat-only change as changed.
515 Instead, silently run `git update-index --refresh` to
516 update the cached stat information for paths whose
517 contents in the work tree match the contents in the
518 index. This option defaults to true. Note that this
519 affects only `git diff` Porcelain, and not lower level
520 `diff` commands, such as `git diff-files`.
521
522 diff.external::
523 If this config variable is set, diff generation is not
524 performed using the internal diff machinery, but using the
525 given command. Note: if you want to use an external diff
526 program only on a subset of your files, you might want to
527 use linkgit:gitattributes[5] instead.
528
529 diff.renameLimit::
530 The number of files to consider when performing the copy/rename
531 detection; equivalent to the git diff option '-l'.
532
533 diff.renames::
534 Tells git to detect renames. If set to any boolean value, it
535 will enable basic rename detection. If set to "copies" or
536 "copy", it will detect copies, as well.
537
538 fetch.unpackLimit::
539 If the number of objects fetched over the git native
540 transfer is below this
541 limit, then the objects will be unpacked into loose object
542 files. However if the number of received objects equals or
543 exceeds this limit then the received pack will be stored as
544 a pack, after adding any missing delta bases. Storing the
545 pack from a push can make the push operation complete faster,
546 especially on slow filesystems. If not set, the value of
547 `transfer.unpackLimit` is used instead.
548
549 format.numbered::
550 A boolean which can enable sequence numbers in patch subjects.
551 Setting this option to "auto" will enable it only if there is
552 more than one patch. See --numbered option in
553 linkgit:git-format-patch[1].
554
555 format.headers::
556 Additional email headers to include in a patch to be submitted
557 by mail. See linkgit:git-format-patch[1].
558
559 format.suffix::
560 The default for format-patch is to output files with the suffix
561 `.patch`. Use this variable to change that suffix (make sure to
562 include the dot if you want it).
563
564 format.pretty::
565 The default pretty format for log/show/whatchanged command,
566 See linkgit:git-log[1], linkgit:git-show[1],
567 linkgit:git-whatchanged[1].
568
569 gc.aggressiveWindow::
570 The window size parameter used in the delta compression
571 algorithm used by 'git gc --aggressive'. This defaults
572 to 10.
573
574 gc.auto::
575 When there are approximately more than this many loose
576 objects in the repository, `git gc --auto` will pack them.
577 Some Porcelain commands use this command to perform a
578 light-weight garbage collection from time to time. The
579 default value is 6700. Setting this to 0 disables it.
580
581 gc.autopacklimit::
582 When there are more than this many packs that are not
583 marked with `*.keep` file in the repository, `git gc
584 --auto` consolidates them into one larger pack. The
585 default value is 50. Setting this to 0 disables it.
586
587 gc.packrefs::
588 `git gc` does not run `git pack-refs` in a bare repository by
589 default so that older dumb-transport clients can still fetch
590 from the repository. Setting this to `true` lets `git
591 gc` to run `git pack-refs`. Setting this to `false` tells
592 `git gc` never to run `git pack-refs`. The default setting is
593 `notbare`. Enable it only when you know you do not have to
594 support such clients. The default setting will change to `true`
595 at some stage, and setting this to `false` will continue to
596 prevent `git pack-refs` from being run from `git gc`.
597
598 gc.pruneexpire::
599 When `git gc` is run, it will call `prune --expire 2.weeks.ago`.
600 Override the grace period with this config variable.
601
602 gc.reflogexpire::
603 `git reflog expire` removes reflog entries older than
604 this time; defaults to 90 days.
605
606 gc.reflogexpireunreachable::
607 `git reflog expire` removes reflog entries older than
608 this time and are not reachable from the current tip;
609 defaults to 30 days.
610
611 gc.rerereresolved::
612 Records of conflicted merge you resolved earlier are
613 kept for this many days when `git rerere gc` is run.
614 The default is 60 days. See linkgit:git-rerere[1].
615
616 gc.rerereunresolved::
617 Records of conflicted merge you have not resolved are
618 kept for this many days when `git rerere gc` is run.
619 The default is 15 days. See linkgit:git-rerere[1].
620
621 rerere.enabled::
622 Activate recording of resolved conflicts, so that identical
623 conflict hunks can be resolved automatically, should they
624 be encountered again. linkgit:git-rerere[1] command is by
625 default enabled if you create `rr-cache` directory under
626 `$GIT_DIR`, but can be disabled by setting this option to false.
627
628 gitcvs.enabled::
629 Whether the CVS server interface is enabled for this repository.
630 See linkgit:git-cvsserver[1].
631
632 gitcvs.logfile::
633 Path to a log file where the CVS server interface well... logs
634 various stuff. See linkgit:git-cvsserver[1].
635
636 gitcvs.allbinary::
637 If true, all files are sent to the client in mode '-kb'. This
638 causes the client to treat all files as binary files which suppresses
639 any newline munging it otherwise might do. A work-around for the
640 fact that there is no way yet to set single files to mode '-kb'.
641
642 gitcvs.dbname::
643 Database used by git-cvsserver to cache revision information
644 derived from the git repository. The exact meaning depends on the
645 used database driver, for SQLite (which is the default driver) this
646 is a filename. Supports variable substitution (see
647 linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
648 Default: '%Ggitcvs.%m.sqlite'
649
650 gitcvs.dbdriver::
651 Used Perl DBI driver. You can specify any available driver
652 for this here, but it might not work. git-cvsserver is tested
653 with 'DBD::SQLite', reported to work with 'DBD::Pg', and
654 reported *not* to work with 'DBD::mysql'. Experimental feature.
655 May not contain double colons (`:`). Default: 'SQLite'.
656 See linkgit:git-cvsserver[1].
657
658 gitcvs.dbuser, gitcvs.dbpass::
659 Database user and password. Only useful if setting 'gitcvs.dbdriver',
660 since SQLite has no concept of database users and/or passwords.
661 'gitcvs.dbuser' supports variable substitution (see
662 linkgit:git-cvsserver[1] for details).
663
664 gitcvs.dbTableNamePrefix::
665 Database table name prefix. Prepended to the names of any
666 database tables used, allowing a single database to be used
667 for several repositories. Supports variable substitution (see
668 linkgit:git-cvsserver[1] for details). Any non-alphabetic
669 characters will be replaced with underscores.
670
671 All gitcvs variables except for 'gitcvs.allbinary' can also be
672 specified as 'gitcvs.<access_method>.<varname>' (where 'access_method'
673 is one of "ext" and "pserver") to make them apply only for the given
674 access method.
675
676 help.browser::
677 Specify the browser that will be used to display help in the
678 'web' format. See linkgit:git-help[1].
679
680 help.format::
681 Override the default help format used by linkgit:git-help[1].
682 Values 'man', 'info', 'web' and 'html' are supported. 'man' is
683 the default. 'web' and 'html' are the same.
684
685 http.proxy::
686 Override the HTTP proxy, normally configured using the 'http_proxy'
687 environment variable (see linkgit:curl[1]). This can be overridden
688 on a per-remote basis; see remote.<name>.proxy
689
690 http.sslVerify::
691 Whether to verify the SSL certificate when fetching or pushing
692 over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
693 variable.
694
695 http.sslCert::
696 File containing the SSL certificate when fetching or pushing
697 over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
698 variable.
699
700 http.sslKey::
701 File containing the SSL private key when fetching or pushing
702 over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
703 variable.
704
705 http.sslCAInfo::
706 File containing the certificates to verify the peer with when
707 fetching or pushing over HTTPS. Can be overridden by the
708 'GIT_SSL_CAINFO' environment variable.
709
710 http.sslCAPath::
711 Path containing files with the CA certificates to verify the peer
712 with when fetching or pushing over HTTPS. Can be overridden
713 by the 'GIT_SSL_CAPATH' environment variable.
714
715 http.maxRequests::
716 How many HTTP requests to launch in parallel. Can be overridden
717 by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
718
719 http.lowSpeedLimit, http.lowSpeedTime::
720 If the HTTP transfer speed is less than 'http.lowSpeedLimit'
721 for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
722 Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
723 'GIT_HTTP_LOW_SPEED_TIME' environment variables.
724
725 http.noEPSV::
726 A boolean which disables using of EPSV ftp command by curl.
727 This can helpful with some "poor" ftp servers which don't
728 support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
729 environment variable. Default is false (curl will use EPSV).
730
731 i18n.commitEncoding::
732 Character encoding the commit messages are stored in; git itself
733 does not care per se, but this information is necessary e.g. when
734 importing commits from emails or in the gitk graphical history
735 browser (and possibly at other places in the future or in other
736 porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
737
738 i18n.logOutputEncoding::
739 Character encoding the commit messages are converted to when
740 running `git-log` and friends.
741
742 instaweb.browser::
743 Specify the program that will be used to browse your working
744 repository in gitweb. See linkgit:git-instaweb[1].
745
746 instaweb.httpd::
747 The HTTP daemon command-line to start gitweb on your working
748 repository. See linkgit:git-instaweb[1].
749
750 instaweb.local::
751 If true the web server started by linkgit:git-instaweb[1] will
752 be bound to the local IP (127.0.0.1).
753
754 instaweb.modulepath::
755 The module path for an apache httpd used by linkgit:git-instaweb[1].
756
757 instaweb.port::
758 The port number to bind the gitweb httpd to. See
759 linkgit:git-instaweb[1].
760
761 log.showroot::
762 If true, the initial commit will be shown as a big creation event.
763 This is equivalent to a diff against an empty tree.
764 Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
765 normally hide the root commit will now show it. True by default.
766
767 man.viewer::
768 Specify the programs that may be used to display help in the
769 'man' format. See linkgit:git-help[1].
770
771 merge.summary::
772 Whether to include summaries of merged commits in newly created
773 merge commit messages. False by default.
774
775 merge.tool::
776 Controls which merge resolution program is used by
777 linkgit:git-mergetool[1]. Valid built-in values are: "kdiff3",
778 "tkdiff", "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", and
779 "opendiff". Any other value is treated is custom merge tool
780 and there must be a corresponing mergetool.<tool>.cmd option.
781
782 merge.verbosity::
783 Controls the amount of output shown by the recursive merge
784 strategy. Level 0 outputs nothing except a final error
785 message if conflicts were detected. Level 1 outputs only
786 conflicts, 2 outputs conflicts and file changes. Level 5 and
787 above outputs debugging information. The default is level 2.
788 Can be overridden by 'GIT_MERGE_VERBOSITY' environment variable.
789
790 merge.<driver>.name::
791 Defines a human readable name for a custom low-level
792 merge driver. See linkgit:gitattributes[5] for details.
793
794 merge.<driver>.driver::
795 Defines the command that implements a custom low-level
796 merge driver. See linkgit:gitattributes[5] for details.
797
798 merge.<driver>.recursive::
799 Names a low-level merge driver to be used when
800 performing an internal merge between common ancestors.
801 See linkgit:gitattributes[5] for details.
802
803 mergetool.<tool>.path::
804 Override the path for the given tool. This is useful in case
805 your tool is not in the PATH.
806
807 mergetool.<tool>.cmd::
808 Specify the command to invoke the specified merge tool. The
809 specified command is evaluated in shell with the following
810 variables available: 'BASE' is the name of a temporary file
811 containing the common base of the files to be merged, if available;
812 'LOCAL' is the name of a temporary file containing the contents of
813 the file on the current branch; 'REMOTE' is the name of a temporary
814 file containing the contents of the file from the branch being
815 merged; 'MERGED' contains the name of the file to which the merge
816 tool should write the results of a successful merge.
817
818 mergetool.<tool>.trustExitCode::
819 For a custom merge command, specify whether the exit code of
820 the merge command can be used to determine whether the merge was
821 successful. If this is not set to true then the merge target file
822 timestamp is checked and the merge assumed to have been successful
823 if the file has been updated, otherwise the user is prompted to
824 indicate the success of the merge.
825
826 mergetool.keepBackup::
827 After performing a merge, the original file with conflict markers
828 can be saved as a file with a `.orig` extension. If this variable
829 is set to `false` then this file is not preserved. Defaults to
830 `true` (i.e. keep the backup files).
831
832 pack.window::
833 The size of the window used by linkgit:git-pack-objects[1] when no
834 window size is given on the command line. Defaults to 10.
835
836 pack.depth::
837 The maximum delta depth used by linkgit:git-pack-objects[1] when no
838 maximum depth is given on the command line. Defaults to 50.
839
840 pack.windowMemory::
841 The window memory size limit used by linkgit:git-pack-objects[1]
842 when no limit is given on the command line. The value can be
843 suffixed with "k", "m", or "g". Defaults to 0, meaning no
844 limit.
845
846 pack.compression::
847 An integer -1..9, indicating the compression level for objects
848 in a pack file. -1 is the zlib default. 0 means no
849 compression, and 1..9 are various speed/size tradeoffs, 9 being
850 slowest. If not set, defaults to core.compression. If that is
851 not set, defaults to -1, the zlib default, which is "a default
852 compromise between speed and compression (currently equivalent
853 to level 6)."
854
855 pack.deltaCacheSize::
856 The maximum memory in bytes used for caching deltas in
857 linkgit:git-pack-objects[1].
858 A value of 0 means no limit. Defaults to 0.
859
860 pack.deltaCacheLimit::
861 The maximum size of a delta, that is cached in
862 linkgit:git-pack-objects[1]. Defaults to 1000.
863
864 pack.threads::
865 Specifies the number of threads to spawn when searching for best
866 delta matches. This requires that linkgit:git-pack-objects[1]
867 be compiled with pthreads otherwise this option is ignored with a
868 warning. This is meant to reduce packing time on multiprocessor
869 machines. The required amount of memory for the delta search window
870 is however multiplied by the number of threads.
871 Specifying 0 will cause git to auto-detect the number of CPU's
872 and set the number of threads accordingly.
873
874 pack.indexVersion::
875 Specify the default pack index version. Valid values are 1 for
876 legacy pack index used by Git versions prior to 1.5.2, and 2 for
877 the new pack index with capabilities for packs larger than 4 GB
878 as well as proper protection against the repacking of corrupted
879 packs. Version 2 is selected and this config option ignored
880 whenever the corresponding pack is larger than 2 GB. Otherwise
881 the default is 1.
882
883 pack.packSizeLimit::
884 The default maximum size of a pack. This setting only affects
885 packing to a file, i.e. the git:// protocol is unaffected. It
886 can be overridden by the `\--max-pack-size` option of
887 linkgit:git-repack[1].
888
889 pull.octopus::
890 The default merge strategy to use when pulling multiple branches
891 at once.
892
893 pull.twohead::
894 The default merge strategy to use when pulling a single branch.
895
896 remote.<name>.url::
897 The URL of a remote repository. See linkgit:git-fetch[1] or
898 linkgit:git-push[1].
899
900 remote.<name>.proxy::
901 For remotes that require curl (http, https and ftp), the URL to
902 the proxy to use for that remote. Set to the empty string to
903 disable proxying for that remote.
904
905 remote.<name>.fetch::
906 The default set of "refspec" for linkgit:git-fetch[1]. See
907 linkgit:git-fetch[1].
908
909 remote.<name>.push::
910 The default set of "refspec" for linkgit:git-push[1]. See
911 linkgit:git-push[1].
912
913 remote.<name>.skipDefaultUpdate::
914 If true, this remote will be skipped by default when updating
915 using the update subcommand of linkgit:git-remote[1].
916
917 remote.<name>.receivepack::
918 The default program to execute on the remote side when pushing. See
919 option \--receive-pack of linkgit:git-push[1].
920
921 remote.<name>.uploadpack::
922 The default program to execute on the remote side when fetching. See
923 option \--upload-pack of linkgit:git-fetch-pack[1].
924
925 remote.<name>.tagopt::
926 Setting this value to \--no-tags disables automatic tag following when
927 fetching from remote <name>
928
929 remotes.<group>::
930 The list of remotes which are fetched by "git remote update
931 <group>". See linkgit:git-remote[1].
932
933 repack.usedeltabaseoffset::
934 Allow linkgit:git-repack[1] to create packs that uses
935 delta-base offset. Defaults to false.
936
937 show.difftree::
938 The default linkgit:git-diff-tree[1] arguments to be used
939 for linkgit:git-show[1].
940
941 showbranch.default::
942 The default set of branches for linkgit:git-show-branch[1].
943 See linkgit:git-show-branch[1].
944
945 status.relativePaths::
946 By default, linkgit:git-status[1] shows paths relative to the
947 current directory. Setting this variable to `false` shows paths
948 relative to the repository root (this was the default for git
949 prior to v1.5.4).
950
951 tar.umask::
952 This variable can be used to restrict the permission bits of
953 tar archive entries. The default is 0002, which turns off the
954 world write bit. The special value "user" indicates that the
955 archiving user's umask will be used instead. See umask(2) and
956 linkgit:git-archive[1].
957
958 url.<base>.insteadOf::
959 Any URL that starts with this value will be rewritten to
960 start, instead, with <base>. In cases where some site serves a
961 large number of repositories, and serves them with multiple
962 access methods, and some users need to use different access
963 methods, this feature allows people to specify any of the
964 equivalent URLs and have git automatically rewrite the URL to
965 the best alternative for the particular user, even for a
966 never-before-seen repository on the site. When more than one
967 insteadOf strings match a given URL, the longest match is used.
968
969 user.email::
970 Your email address to be recorded in any newly created commits.
971 Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
972 'EMAIL' environment variables. See linkgit:git-commit-tree[1].
973
974 user.name::
975 Your full name to be recorded in any newly created commits.
976 Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
977 environment variables. See linkgit:git-commit-tree[1].
978
979 user.signingkey::
980 If linkgit:git-tag[1] is not selecting the key you want it to
981 automatically when creating a signed tag, you can override the
982 default selection with this variable. This option is passed
983 unchanged to gpg's --local-user parameter, so you may specify a key
984 using any method that gpg supports.
985
986 whatchanged.difftree::
987 The default linkgit:git-diff-tree[1] arguments to be used
988 for linkgit:git-whatchanged[1].
989
990 imap::
991 The configuration variables in the 'imap' section are described
992 in linkgit:git-imap-send[1].
993
994 receive.fsckObjects::
995 If it is set to true, git-receive-pack will check all received
996 objects. It will abort in the case of a malformed object or a
997 broken link. The result of an abort are only dangling objects.
998 Defaults to false.
999
1000 receive.unpackLimit::
1001 If the number of objects received in a push is below this
1002 limit then the objects will be unpacked into loose object
1003 files. However if the number of received objects equals or
1004 exceeds this limit then the received pack will be stored as
1005 a pack, after adding any missing delta bases. Storing the
1006 pack from a push can make the push operation complete faster,
1007 especially on slow filesystems. If not set, the value of
1008 `transfer.unpackLimit` is used instead.
1009
1010 receive.denyNonFastForwards::
1011 If set to true, git-receive-pack will deny a ref update which is
1012 not a fast forward. Use this to prevent such an update via a push,
1013 even if that push is forced. This configuration variable is
1014 set when initializing a shared repository.
1015
1016 transfer.unpackLimit::
1017 When `fetch.unpackLimit` or `receive.unpackLimit` are
1018 not set, the value of this variable is used instead.
1019 The default value is 100.
1020
1021 web.browser::
1022 Specify a web browser that may be used by some commands.
1023 Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1024 may use it.
