Raw
1 core.fileMode::
2 Tells Git if the executable bit of files in the working tree
3 is to be honored.
4 +
5 Some filesystems lose the executable bit when a file that is
6 marked as executable is checked out, or checks out a
7 non-executable file with executable bit on.
8 linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
9 to see if it handles the executable bit correctly
10 and this variable is automatically set as necessary.
11 +
12 A repository, however, may be on a filesystem that handles
13 the filemode correctly, and this variable is set to 'true'
14 when created, but later may be made accessible from another
15 environment that loses the filemode (e.g. exporting ext4 via
16 CIFS mount, visiting a Cygwin created repository with
17 Git for Windows or Eclipse).
18 In such a case it may be necessary to set this variable to 'false'.
19 See linkgit:git-update-index[1].
20 +
21 The default is true (when core.filemode is not specified in the config file).
22
23 core.hideDotFiles::
24 (Windows-only) If true, mark newly-created directories and files whose
25 name starts with a dot as hidden. If 'dotGitOnly', only the `.git/`
26 directory is hidden, but no other files starting with a dot. The
27 default mode is 'dotGitOnly'.
28
29 core.ignoreCase::
30 Internal variable which enables various workarounds to enable
31 Git to work better on filesystems that are not case sensitive,
32 like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing
33 finds "makefile" when Git expects "Makefile", Git will assume
34 it is really the same file, and continue to remember it as
35 "Makefile".
36 +
37 The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
38 will probe and set core.ignoreCase true if appropriate when the repository
39 is created.
40 +
41 Git relies on the proper configuration of this variable for your operating
42 and file system. Modifying this value may result in unexpected behavior.
43
44 core.precomposeUnicode::
45 This option is only used by Mac OS implementation of Git.
46 When core.precomposeUnicode=true, Git reverts the unicode decomposition
47 of filenames done by Mac OS. This is useful when sharing a repository
48 between Mac OS and Linux or Windows.
49 (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
50 When false, file names are handled fully transparent by Git,
51 which is backward compatible with older versions of Git.
52
53 core.protectHFS::
54 If set to true, do not allow checkout of paths that would
55 be considered equivalent to `.git` on an HFS+ filesystem.
56 Defaults to `true` on Mac OS, and `false` elsewhere.
57
58 core.protectNTFS::
59 If set to true, do not allow checkout of paths that would
60 cause problems with the NTFS filesystem, e.g. conflict with
61 8.3 "short" names.
62 Defaults to `true` on Windows, and `false` elsewhere.
63
64 core.fsmonitor::
65 If set to true, enable the built-in file system monitor
66 daemon for this working directory (linkgit:git-fsmonitor{litdd}daemon[1]).
67 +
68 Like hook-based file system monitors, the built-in file system monitor
69 can speed up Git commands that need to refresh the Git index
70 (e.g. `git status`) in a working directory with many files. The
71 built-in monitor eliminates the need to install and maintain an
72 external third-party tool.
73 +
74 The built-in file system monitor is currently available only on a
75 limited set of supported platforms. Currently, this includes Windows
76 and MacOS.
77 +
78 Otherwise, this variable contains the pathname of the "fsmonitor"
79 hook command.
80 +
81 This hook command is used to identify all files that may have changed
82 since the requested date/time. This information is used to speed up
83 git by avoiding unnecessary scanning of files that have not changed.
84 +
85 See the "fsmonitor-watchman" section of linkgit:githooks[5].
86 +
87 Note that if you concurrently use multiple versions of Git, such
88 as one version on the command line and another version in an IDE
89 tool, that the definition of `core.fsmonitor` was extended to
90 allow boolean values in addition to hook pathnames. Git versions
91 2.35.1 and prior will not understand the boolean values and will
92 consider the "true" or "false" values as hook pathnames to be
93 invoked. Git versions 2.26 thru 2.35.1 default to hook protocol
94 V2 and will fall back to no fsmonitor (full scan). Git versions
95 prior to 2.26 default to hook protocol V1 and will silently
96 assume there were no changes to report (no scan), so status
97 commands may report incomplete results. For this reason, it is
98 best to upgrade all of your Git versions before using the built-in
99 file system monitor.
100
101 core.fsmonitorHookVersion::
102 Sets the protocol version to be used when invoking the
103 "fsmonitor" hook.
104 +
105 There are currently versions 1 and 2. When this is not set,
106 version 2 will be tried first and if it fails then version 1
107 will be tried. Version 1 uses a timestamp as input to determine
108 which files have changes since that time but some monitors
109 like Watchman have race conditions when used with a timestamp.
110 Version 2 uses an opaque string so that the monitor can return
111 something that can be used to determine what files have changed
112 without race conditions.
113
114 core.trustctime::
115 If false, the ctime differences between the index and the
116 working tree are ignored; useful when the inode change time
117 is regularly modified by something outside Git (file system
118 crawlers and some backup systems).
119 See linkgit:git-update-index[1]. True by default.
120
121 core.splitIndex::
122 If true, the split-index feature of the index will be used.
123 See linkgit:git-update-index[1]. False by default.
124
125 core.untrackedCache::
126 Determines what to do about the untracked cache feature of the
127 index. It will be kept, if this variable is unset or set to
128 `keep`. It will automatically be added if set to `true`. And
129 it will automatically be removed, if set to `false`. Before
130 setting it to `true`, you should check that mtime is working
131 properly on your system.
132 See linkgit:git-update-index[1]. `keep` by default, unless
133 `feature.manyFiles` is enabled which sets this setting to
134 `true` by default.
135
136 core.checkStat::
137 When missing or is set to `default`, many fields in the stat
138 structure are checked to detect if a file has been modified
139 since Git looked at it. When this configuration variable is
140 set to `minimal`, sub-second part of mtime and ctime, the
141 uid and gid of the owner of the file, the inode number (and
142 the device number, if Git was compiled to use it), are
143 excluded from the check among these fields, leaving only the
144 whole-second part of mtime (and ctime, if `core.trustCtime`
145 is set) and the filesize to be checked.
146 +
147 There are implementations of Git that do not leave usable values in
148 some fields (e.g. JGit); by excluding these fields from the
149 comparison, the `minimal` mode may help interoperability when the
150 same repository is used by these other systems at the same time.
151
152 core.quotePath::
153 Commands that output paths (e.g. 'ls-files', 'diff'), will
154 quote "unusual" characters in the pathname by enclosing the
155 pathname in double-quotes and escaping those characters with
156 backslashes in the same way C escapes control characters (e.g.
157 `\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with
158 values larger than 0x80 (e.g. octal `\302\265` for "micro" in
159 UTF-8). If this variable is set to false, bytes higher than
160 0x80 are not considered "unusual" any more. Double-quotes,
161 backslash and control characters are always escaped regardless
162 of the setting of this variable. A simple space character is
163 not considered "unusual". Many commands can output pathnames
164 completely verbatim using the `-z` option. The default value
165 is true.
166
167 core.eol::
168 Sets the line ending type to use in the working directory for
169 files that are marked as text (either by having the `text`
170 attribute set, or by having `text=auto` and Git auto-detecting
171 the contents as text).
172 Alternatives are 'lf', 'crlf' and 'native', which uses the platform's
173 native line ending. The default value is `native`. See
174 linkgit:gitattributes[5] for more information on end-of-line
175 conversion. Note that this value is ignored if `core.autocrlf`
176 is set to `true` or `input`.
177
178 core.safecrlf::
179 If true, makes Git check if converting `CRLF` is reversible when
180 end-of-line conversion is active. Git will verify if a command
181 modifies a file in the work tree either directly or indirectly.
182 For example, committing a file followed by checking out the
183 same file should yield the original file in the work tree. If
184 this is not the case for the current setting of
185 `core.autocrlf`, Git will reject the file. The variable can
186 be set to "warn", in which case Git will only warn about an
187 irreversible conversion but continue the operation.
188 +
189 CRLF conversion bears a slight chance of corrupting data.
190 When it is enabled, Git will convert CRLF to LF during commit and LF to
191 CRLF during checkout. A file that contains a mixture of LF and
192 CRLF before the commit cannot be recreated by Git. For text
193 files this is the right thing to do: it corrects line endings
194 such that we have only LF line endings in the repository.
195 But for binary files that are accidentally classified as text the
196 conversion can corrupt data.
197 +
198 If you recognize such corruption early you can easily fix it by
199 setting the conversion type explicitly in .gitattributes. Right
200 after committing you still have the original file in your work
201 tree and this file is not yet corrupted. You can explicitly tell
202 Git that this file is binary and Git will handle the file
203 appropriately.
204 +
205 Unfortunately, the desired effect of cleaning up text files with
206 mixed line endings and the undesired effect of corrupting binary
207 files cannot be distinguished. In both cases CRLFs are removed
208 in an irreversible way. For text files this is the right thing
209 to do because CRLFs are line endings, while for binary files
210 converting CRLFs corrupts data.
211 +
212 Note, this safety check does not mean that a checkout will generate a
213 file identical to the original file for a different setting of
214 `core.eol` and `core.autocrlf`, but only for the current one. For
215 example, a text file with `LF` would be accepted with `core.eol=lf`
216 and could later be checked out with `core.eol=crlf`, in which case the
217 resulting file would contain `CRLF`, although the original file
218 contained `LF`. However, in both work trees the line endings would be
219 consistent, that is either all `LF` or all `CRLF`, but never mixed. A
220 file with mixed line endings would be reported by the `core.safecrlf`
221 mechanism.
222
223 core.autocrlf::
224 Setting this variable to "true" is the same as setting
225 the `text` attribute to "auto" on all files and core.eol to "crlf".
226 Set to true if you want to have `CRLF` line endings in your
227 working directory and the repository has LF line endings.
228 This variable can be set to 'input',
229 in which case no output conversion is performed.
230
231 core.checkRoundtripEncoding::
232 A comma and/or whitespace separated list of encodings that Git
233 performs UTF-8 round trip checks on if they are used in an
234 `working-tree-encoding` attribute (see linkgit:gitattributes[5]).
235 The default value is `SHIFT-JIS`.
236
237 core.symlinks::
238 If false, symbolic links are checked out as small plain files that
239 contain the link text. linkgit:git-update-index[1] and
240 linkgit:git-add[1] will not change the recorded type to regular
241 file. Useful on filesystems like FAT that do not support
242 symbolic links.
243 +
244 The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
245 will probe and set core.symlinks false if appropriate when the repository
246 is created.
247
248 core.gitProxy::
249 A "proxy command" to execute (as 'command host port') instead
250 of establishing direct connection to the remote server when
251 using the Git protocol for fetching. If the variable value is
252 in the "COMMAND for DOMAIN" format, the command is applied only
253 on hostnames ending with the specified domain string. This variable
254 may be set multiple times and is matched in the given order;
255 the first match wins.
256 +
257 Can be overridden by the `GIT_PROXY_COMMAND` environment variable
258 (which always applies universally, without the special "for"
259 handling).
260 +
261 The special string `none` can be used as the proxy command to
262 specify that no proxy be used for a given domain pattern.
263 This is useful for excluding servers inside a firewall from
264 proxy use, while defaulting to a common proxy for external domains.
265
266 core.sshCommand::
267 If this variable is set, `git fetch` and `git push` will
268 use the specified command instead of `ssh` when they need to
269 connect to a remote system. The command is in the same form as
270 the `GIT_SSH_COMMAND` environment variable and is overridden
271 when the environment variable is set.
272
273 core.ignoreStat::
274 If true, Git will avoid using lstat() calls to detect if files have
275 changed by setting the "assume-unchanged" bit for those tracked files
276 which it has updated identically in both the index and working tree.
277 +
278 When files are modified outside of Git, the user will need to stage
279 the modified files explicitly (e.g. see 'Examples' section in
280 linkgit:git-update-index[1]).
281 Git will not normally detect changes to those files.
282 +
283 This is useful on systems where lstat() calls are very slow, such as
284 CIFS/Microsoft Windows.
285 +
286 False by default.
287
288 core.preferSymlinkRefs::
289 Instead of the default "symref" format for HEAD
290 and other symbolic reference files, use symbolic links.
291 This is sometimes needed to work with old scripts that
292 expect HEAD to be a symbolic link.
293 +
294 This configuration is deprecated and will be removed in Git 3.0. Symbolic refs
295 will always be written as textual symrefs.
296
297 core.alternateRefsCommand::
298 When advertising tips of available history from an alternate, use the shell to
299 execute the specified command instead of linkgit:git-for-each-ref[1]. The
300 first argument is the absolute path of the alternate. Output must contain one
301 hex object id per line (i.e., the same as produced by `git for-each-ref
302 --format='%(objectname)'`).
303 +
304 Note that you cannot generally put `git for-each-ref` directly into the config
305 value, as it does not take a repository path as an argument (but you can wrap
306 the command above in a shell script).
307
308 core.alternateRefsPrefixes::
309 When listing references from an alternate, list only references that begin
310 with the given prefix. Prefixes match as if they were given as arguments to
311 linkgit:git-for-each-ref[1]. To list multiple prefixes, separate them with
312 whitespace. If `core.alternateRefsCommand` is set, setting
313 `core.alternateRefsPrefixes` has no effect.
314
315 core.bare::
316 If true this repository is assumed to be 'bare' and has no
317 working directory associated with it. If this is the case a
318 number of commands that require a working directory will be
319 disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
320 +
321 This setting is automatically guessed by linkgit:git-clone[1] or
322 linkgit:git-init[1] when the repository was created. By default a
323 repository that ends in "/.git" is assumed to be not bare (bare =
324 false), while all other repositories are assumed to be bare (bare
325 = true).
326
327 core.worktree::
328 Set the path to the root of the working tree.
329 If `GIT_COMMON_DIR` environment variable is set, core.worktree
330 is ignored and not used for determining the root of working tree.
331 This can be overridden by the `GIT_WORK_TREE` environment
332 variable and the `--work-tree` command-line option.
333 The value can be an absolute path or relative to the path to
334 the .git directory, which is either specified by --git-dir
335 or GIT_DIR, or automatically discovered.
336 If --git-dir or GIT_DIR is specified but none of
337 --work-tree, GIT_WORK_TREE and core.worktree is specified,
338 the current working directory is regarded as the top level
339 of your working tree.
340 +
341 Note that this variable is honored even when set in a configuration
342 file in a ".git" subdirectory of a directory and its value differs
343 from the latter directory (e.g. "/path/to/.git/config" has
344 core.worktree set to "/different/path"), which is most likely a
345 misconfiguration. Running Git commands in the "/path/to" directory will
346 still use "/different/path" as the root of the work tree and can cause
347 confusion unless you know what you are doing (e.g. you are creating a
348 read-only snapshot of the same index to a location different from the
349 repository's usual working tree).
350
351 core.lockfilePid::
352 If true, Git will create a PID file alongside lock files. When a
353 lock acquisition fails and a PID file exists, Git can provide
354 additional diagnostic information about the process holding the
355 lock, including whether it is still running. Defaults to `false`.
356 +
357 The PID file is named by inserting `~pid` before the `.lock` suffix.
358 For example, if the lock file is `index.lock`, the PID file will be
359 `index~pid.lock`. The file contains a single line in the format
360 `pid <value>` followed by a newline.
361
362 core.logAllRefUpdates::
363 Enable the reflog. Updates to a ref <ref> is logged to the file
364 "`$GIT_DIR/logs/<ref>`", by appending the new and old
365 SHA-1, the date/time and the reason of the update, but
366 only when the file exists. If this configuration
367 variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`"
368 file is automatically created for branch heads (i.e. under
369 `refs/heads/`), remote refs (i.e. under `refs/remotes/`),
370 note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`.
371 If it is set to `always`, then a missing reflog is automatically
372 created for any ref under `refs/`.
373 +
374 This information can be used to determine what commit
375 was the tip of a branch "2 days ago".
376 +
377 This value is true by default in a repository that has
378 a working directory associated with it, and false by
379 default in a bare repository.
380
381 core.repositoryFormatVersion::
382 Internal variable identifying the repository format and layout
383 version. See linkgit:gitrepository-layout[5].
384
385 core.sharedRepository::
386 When 'group' (or 'true'), the repository is made shareable between
387 several users in a group (making sure all the files and objects are
388 group-writable). When 'all' (or 'world' or 'everybody'), the
389 repository will be readable by all users, additionally to being
390 group-shareable. When 'umask' (or 'false'), Git will use permissions
391 reported by umask(2). When '0xxx', where '0xxx' is an octal number,
392 files in the repository will have this mode value. '0xxx' will override
393 user's umask value (whereas the other options will only override
394 requested parts of the user's umask value). Examples: '0660' will make
395 the repo read/write-able for the owner and group, but inaccessible to
396 others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
397 repository that is group-readable but not group-writable.
398 See linkgit:git-init[1]. False by default.
399
400 core.warnAmbiguousRefs::
401 If true, Git will warn you if the ref name you passed it is ambiguous
402 and might match multiple refs in the repository. True by default.
403
404 core.compression::
405 An integer -1..9, indicating a default compression level.
406 -1 is the zlib default. 0 means no compression,
407 and 1..9 are various speed/size tradeoffs, 9 being slowest.
408 If set, this provides a default to other compression variables,
409 such as `core.looseCompression` and `pack.compression`.
410
411 core.looseCompression::
412 An integer -1..9, indicating the compression level for objects that
413 are not in a pack file. -1 is the zlib default. 0 means no
414 compression, and 1..9 are various speed/size tradeoffs, 9 being
415 slowest. If not set, defaults to core.compression. If that is
416 not set, defaults to 1 (best speed).
417
418 core.packedGitWindowSize::
419 Number of bytes of a pack file to map into memory in a
420 single mapping operation. Larger window sizes may allow
421 your system to process a smaller number of large pack files
422 more quickly. Smaller window sizes will negatively affect
423 performance due to increased calls to the operating system's
424 memory manager, but may improve performance when accessing
425 a large number of large pack files.
426 +
427 Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
428 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should
429 be reasonable for all users/operating systems. You probably do
430 not need to adjust this value.
431 +
432 Common unit suffixes of 'k', 'm', or 'g' are supported.
433
434 core.packedGitLimit::
435 Maximum number of bytes to map simultaneously into memory
436 from pack files. If Git needs to access more than this many
437 bytes at once to complete an operation it will unmap existing
438 regions to reclaim virtual address space within the process.
439 +
440 Default is 256 MiB on 32 bit platforms and 32 TiB (effectively
441 unlimited) on 64 bit platforms.
442 This should be reasonable for all users/operating systems, except on
443 the largest projects. You probably do not need to adjust this value.
444 +
445 Common unit suffixes of 'k', 'm', or 'g' are supported.
446
447 core.deltaBaseCacheLimit::
448 Maximum number of bytes per thread to reserve for caching base objects
449 that may be referenced by multiple deltified objects. By storing the
450 entire decompressed base objects in a cache Git is able
451 to avoid unpacking and decompressing frequently used base
452 objects multiple times.
453 +
454 Default is 96 MiB on all platforms. This should be reasonable
455 for all users/operating systems, except on the largest projects.
456 You probably do not need to adjust this value.
457 +
458 Common unit suffixes of 'k', 'm', or 'g' are supported.
459
460 core.bigFileThreshold::
461 The size of files considered "big", which as discussed below
462 changes the behavior of numerous git commands, as well as how
463 such files are stored within the repository. The default is
464 512 MiB. Common unit suffixes of 'k', 'm', or 'g' are
465 supported.
466 +
467 Files above the configured limit will be:
468 +
469 * Stored deflated in packfiles, without attempting delta compression.
470 +
471 The default limit is primarily set with this use-case in mind. With it,
472 most projects will have their source code and other text files delta
473 compressed, but not larger binary media files.
474 +
475 Storing large files without delta compression avoids excessive memory
476 usage, at the slight expense of increased disk usage.
477 +
478 * Will be treated as if they were labeled "binary" (see
479 linkgit:gitattributes[5]). e.g. linkgit:git-log[1] and
480 linkgit:git-diff[1] will not compute diffs for files above this limit.
481 +
482 * Will generally be streamed when written, which avoids excessive
483 memory usage, at the cost of some fixed overhead. Commands that make
484 use of this include linkgit:git-archive[1],
485 linkgit:git-fast-import[1], linkgit:git-index-pack[1],
486 linkgit:git-unpack-objects[1] and linkgit:git-fsck[1].
487
488 core.excludesFile::
489 Specifies the pathname to the file that contains patterns to
490 describe paths that are not meant to be tracked, in addition
491 to `.gitignore` (per-directory) and `.git/info/exclude`.
492 Defaults to `$XDG_CONFIG_HOME/git/ignore`.
493 If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore`
494 is used instead. See linkgit:gitignore[5].
495
496 core.askPass::
497 Some commands (e.g. svn and http interfaces) that interactively
498 ask for a password can be told to use an external program given
499 via the value of this variable. Can be overridden by the `GIT_ASKPASS`
500 environment variable. If not set, fall back to the value of the
501 `SSH_ASKPASS` environment variable or, failing that, a simple password
502 prompt. The external program shall be given a suitable prompt as
503 command-line argument and write the password on its STDOUT.
504
505 core.attributesFile::
506 Specifies the pathname to the file that contains attributes (see
507 linkgit:gitattributes[5]), in addition to `.gitattributes` (per-directory)
508 and `.git/info/attributes`. Its default value is
509 `$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not
510 set or empty, `$HOME/.config/git/attributes` is used instead.
511
512 core.hooksPath::
513 By default Git will look for your hooks in the
514 `$GIT_DIR/hooks` directory. Set this to different path,
515 e.g. `/etc/git/hooks`, and Git will try to find your hooks in
516 that directory, e.g. `/etc/git/hooks/pre-receive` instead of
517 in `$GIT_DIR/hooks/pre-receive`.
518 +
519 The path can be either absolute or relative. A relative path is
520 taken as relative to the directory where the hooks are run (see
521 the "DESCRIPTION" section of linkgit:githooks[5]).
522 +
523 This configuration variable is useful in cases where you'd like to
524 centrally configure your Git hooks instead of configuring them on a
525 per-repository basis, or as a more flexible and centralized
526 alternative to having an `init.templateDir` where you've changed
527 default hooks.
528 +
529 You can also disable all hooks entirely by setting `core.hooksPath`
530 to `/dev/null`. This is usually only advisable for expert users and
531 on a per-command basis using configuration parameters of the form
532 `git -c core.hooksPath=/dev/null ...`.
533
534 core.editor::
535 Commands such as `commit` and `tag` that let you edit
536 messages by launching an editor use the value of this
537 variable when it is set, and the environment variable
538 `GIT_EDITOR` is not set. See linkgit:git-var[1].
539
540 core.commentChar::
541 core.commentString::
542 Commands such as `commit` and `tag` that let you edit
543 messages consider a line that begins with this character
544 commented, and removes them after the editor returns
545 (default '#').
546 +
547 ifndef::with-breaking-changes[]
548 If set to "auto", `git-commit` will select a character that is not
549 the beginning character of any line in existing commit messages.
550 Support for this value is deprecated and will be removed in Git 3.0
551 due to the following limitations:
552 +
553 --
554 * It is incompatible with adding comments in a commit message
555 template. This includes the conflicts comments added to
556 the commit message by `cherry-pick`, `merge`, `rebase` and
557 `revert`.
558 * It is incompatible with adding comments to the commit message
559 in the `prepare-commit-msg` hook.
560 * It is incompatible with the `fixup` and `squash` commands when
561 rebasing,
562 * It is not respected by `git notes`
563 --
564 +
565 endif::with-breaking-changes[]
566 Note that these two variables are aliases of each other, and in modern
567 versions of Git you are free to use a string (e.g., `//` or `⁑⁕⁑`) with
568 `commentChar`. Versions of Git prior to v2.45.0 will ignore
569 `commentString` but will reject a value of `commentChar` that consists
570 of more than a single ASCII byte. If you plan to use your config with
571 older and newer versions of Git, you may want to specify both:
572 +
573 [core]
574 # single character for older versions
575 commentChar = "#"
576 # string for newer versions (which will override commentChar
577 # because it comes later in the file)
578 commentString = "//"
579
580 core.filesRefLockTimeout::
581 The length of time, in milliseconds, to retry when trying to
582 lock an individual reference. Value 0 means not to retry at
583 all; -1 means to try indefinitely. Default is 100 (i.e.,
584 retry for 100ms).
585
586 core.packedRefsTimeout::
587 The length of time, in milliseconds, to retry when trying to
588 lock the `packed-refs` file. Value 0 means not to retry at
589 all; -1 means to try indefinitely. Default is 1000 (i.e.,
590 retry for 1 second).
591
592 core.configLockTimeout::
593 The length of time, in milliseconds, to retry when trying to
594 lock a configuration file for writing. Value 0 means not to
595 retry at all; -1 means to try indefinitely. Default is 1000
596 (i.e., retry for 1 second). This is read from the configuration
597 that is already on disk before the lock is taken, so it can be
598 set persistently like any other option.
599
600 core.pager::
601 Text viewer for use by Git commands (e.g., 'less'). The value
602 is meant to be interpreted by the shell. The order of preference
603 is the `$GIT_PAGER` environment variable, then `core.pager`
604 configuration, then `$PAGER`, and then the default chosen at
605 compile time (usually 'less').
606 +
607 When the `LESS` environment variable is unset, Git sets it to `FRX`
608 (if `LESS` environment variable is set, Git does not change it at
609 all). If you want to selectively override Git's default setting
610 for `LESS`, you can set `core.pager` to e.g. `less -S`. This will
611 be passed to the shell by Git, which will translate the final
612 command to `LESS=FRX less -S`. The environment does not set the
613 `S` option but the command line does, instructing less to truncate
614 long lines. Similarly, setting `core.pager` to `less -+F` will
615 deactivate the `F` option specified by the environment from the
616 command-line, deactivating the "quit if one screen" behavior of
617 `less`. One can specifically activate some flags for particular
618 commands: for example, setting `pager.blame` to `less -S` enables
619 line truncation only for `git blame`.
620 +
621 Likewise, when the `LV` environment variable is unset, Git sets it
622 to `-c`. You can override this setting by exporting `LV` with
623 another value or setting `core.pager` to `lv +c`.
624
625 core.whitespace::
626 A comma separated list of common whitespace problems to
627 notice. 'git diff' will use `color.diff.whitespace` to
628 highlight them, and 'git apply --whitespace=error' will
629 consider them as errors. You can prefix `-` to disable
630 any of them (e.g. `-trailing-space`):
631 +
632 * `blank-at-eol` treats trailing whitespaces at the end of the line
633 as an error (enabled by default).
634 * `space-before-tab` treats a space character that appears immediately
635 before a tab character in the initial indent part of the line as an
636 error (enabled by default).
637 * `indent-with-non-tab` treats a line that is indented with space
638 characters instead of the equivalent tabs as an error (not enabled by
639 default).
640 * `tab-in-indent` treats a tab character in the initial indent part of
641 the line as an error (not enabled by default).
642 * `blank-at-eof` treats blank lines added at the end of file as an error
643 (enabled by default).
644 * `trailing-space` is a short-hand to cover both `blank-at-eol` and
645 `blank-at-eof`.
646 * `cr-at-eol` treats a carriage-return at the end of line as
647 part of the line terminator, i.e. with it, `trailing-space`
648 does not trigger if the character before such a carriage-return
649 is not a whitespace (not enabled by default).
650 * `incomplete-line` treats the last line of a file that is missing the
651 newline at the end as an error (not enabled by default).
652 * `tabwidth=<n>` tells how many character positions a tab occupies; this
653 is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
654 errors. The default tab width is 8. Allowed values are 1 to 63.
655
656 core.fsync::
657 A comma-separated list of components of the repository that
658 should be hardened via the core.fsyncMethod when created or
659 modified. You can disable hardening of any component by
660 prefixing it with a '-'. Items that are not hardened may be
661 lost in the event of an unclean system shutdown. Unless you
662 have special requirements, it is recommended that you leave
663 this option empty or pick one of `committed`, `added`,
664 or `all`.
665 +
666 When this configuration is encountered, the set of components starts with
667 the platform default value, disabled components are removed, and additional
668 components are added. `none` resets the state so that the platform default
669 is ignored.
670 +
671 The empty string resets the fsync configuration to the platform
672 default. The default on most platforms is equivalent to
673 `core.fsync=committed,-loose-object`, which has good performance,
674 but risks losing recent work in the event of an unclean system shutdown.
675 +
676 * `none` clears the set of fsynced components.
677 * `loose-object` hardens objects added to the repo in loose-object form.
678 * `pack` hardens objects added to the repo in packfile form.
679 * `pack-metadata` hardens packfile bitmaps and indexes.
680 * `commit-graph` hardens the commit-graph file.
681 * `index` hardens the index when it is modified.
682 * `objects` is an aggregate option that is equivalent to
683 `loose-object,pack`.
684 * `reference` hardens references modified in the repo.
685 * `derived-metadata` is an aggregate option that is equivalent to
686 `pack-metadata,commit-graph`.
687 * `committed` is an aggregate option that is currently equivalent to
688 `objects`. This mode sacrifices some performance to ensure that work
689 that is committed to the repository with `git commit` or similar commands
690 is hardened.
691 * `added` is an aggregate option that is currently equivalent to
692 `committed,index`. This mode sacrifices additional performance to
693 ensure that the results of commands like `git add` and similar operations
694 are hardened.
695 * `all` is an aggregate option that syncs all individual components above.
696
697 core.fsyncMethod::
698 A value indicating the strategy Git will use to harden repository data
699 using fsync and related primitives.
700 +
701 * `fsync` uses the fsync() system call or platform equivalents.
702 * `writeout-only` issues pagecache writeback requests, but depending on the
703 filesystem and storage hardware, data added to the repository may not be
704 durable in the event of a system crash. This is the default mode on macOS.
705 * `batch` enables a mode that uses writeout-only flushes to stage multiple
706 updates in the disk writeback cache and then does a single full fsync of
707 a dummy file to trigger the disk cache flush at the end of the operation.
708 +
709 Currently `batch` mode only applies to loose-object files. Other repository
710 data is made durable as if `fsync` was specified. This mode is expected to
711 be as safe as `fsync` on macOS for repos stored on HFS+ or APFS filesystems
712 and on Windows for repos stored on NTFS or ReFS filesystems.
713
714 core.fsyncObjectFiles::
715 This boolean will enable 'fsync()' when writing object files.
716 This setting is deprecated. Use core.fsync instead.
717 +
718 This setting affects data added to the Git repository in loose-object
719 form. When set to true, Git will issue an fsync or similar system call
720 to flush caches so that loose-objects remain consistent in the face
721 of a unclean system shutdown.
722
723 core.preloadIndex::
724 Enable parallel index preload for operations like 'git diff'
725 +
726 This can speed up operations like 'git diff' and 'git status' especially
727 on filesystems like NFS that have weak caching semantics and thus
728 relatively high IO latencies. When enabled, Git will do the
729 index comparison to the filesystem data in parallel, allowing
730 overlapping IO's. Defaults to true.
731
732 core.unsetenvvars::
733 Windows-only: comma-separated list of environment variables'
734 names that need to be unset before spawning any other process.
735 Defaults to `PERL5LIB` to account for the fact that Git for
736 Windows insists on using its own Perl interpreter.
737
738 core.createObject::
739 You can set this to 'link', in which case a hardlink followed by
740 a delete of the source are used to make sure that object creation
741 will not overwrite existing objects.
742 +
743 On some file system/operating system combinations, this is unreliable.
744 Set this config setting to 'rename' there; however, this will remove the
745 check that makes sure that existing object files will not get overwritten.
746
747 core.notesRef::
748 When showing commit messages, also show notes which are stored in
749 the given ref. The ref must be fully qualified. If the given
750 ref does not exist, it is not an error but means that no
751 notes should be printed.
752 +
753 This setting defaults to "refs/notes/commits", and it can be overridden by
754 the `GIT_NOTES_REF` environment variable. See linkgit:git-notes[1].
755
756 core.commitGraph::
757 If true, then git will read the commit-graph file (if it exists)
758 to parse the graph structure of commits. Defaults to true. See
759 linkgit:git-commit-graph[1] for more information.
760
761 core.useReplaceRefs::
762 If set to `false`, behave as if the `--no-replace-objects`
763 option was given on the command line. See linkgit:git[1] and
764 linkgit:git-replace[1] for more information.
765
766 core.multiPackIndex::
767 Use the multi-pack-index file to track multiple packfiles using a
768 single index. See linkgit:git-multi-pack-index[1] for more
769 information. Defaults to true.
770
771 core.sparseCheckout::
772 Enable "sparse checkout" feature. See linkgit:git-sparse-checkout[1]
773 for more information.
774
775 core.sparseCheckoutCone::
776 Enables the "cone mode" of the sparse checkout feature. When the
777 sparse-checkout file contains a limited set of patterns, this
778 mode provides significant performance advantages. The "non-cone
779 mode" can be requested to allow specifying more flexible
780 patterns by setting this variable to 'false'. See
781 linkgit:git-sparse-checkout[1] for more information.
782
783 core.abbrev::
784 Set the length object names are abbreviated to. If
785 unspecified or set to "auto", an appropriate value is
786 computed based on the approximate number of packed objects
787 in your repository, which hopefully is enough for
788 abbreviated object names to stay unique for some time.
789 If set to "no", no abbreviation is made and the object names
790 are shown in their full length.
791 The minimum length is 4.
792
793 core.maxTreeDepth::
794 The maximum depth Git is willing to recurse while traversing a
795 tree (e.g., "a/b/cde/f" has a depth of 4). This is a fail-safe
796 to allow Git to abort cleanly, and should not generally need to
797 be adjusted. When Git is compiled with MSVC, the default is 512.
798 Otherwise, the default is 2048.
