If 'dotGitOnly', only the `.git/` - directory is hidden, but no other files starting with a dot. The - default mode is 'dotGitOnly'. - -core.ignoreCase:: - Internal variable which enables various workarounds to enable - Git to work better on filesystems that are not case sensitive, - like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing - finds "makefile" when Git expects "Makefile", Git will assume - it is really the same file, and continue to remember it as - "Makefile". -+ -The default is false, except linkgit:git-clone[1] or linkgit:git-init[1] -will probe and set core.ignoreCase true if appropriate when the repository -is created. -+ -Git relies on the proper configuration of this variable for your operating -and file system. Modifying this value may result in unexpected behavior. - -core.precomposeUnicode:: - This option is only used by Mac OS implementation of Git. - When core.precomposeUnicode=true, Git reverts the unicode decomposition - of filenames done by Mac OS. This is useful when sharing a repository - between Mac OS and Linux or Windows. - (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). - When false, file names are handled fully transparent by Git, - which is backward compatible with older versions of Git. - -core.protectHFS:: - If set to true, do not allow checkout of paths that would - be considered equivalent to `.git` on an HFS+ filesystem. - Defaults to `true` on Mac OS, and `false` elsewhere. - -core.protectNTFS:: - If set to true, do not allow checkout of paths that would - cause problems with the NTFS filesystem, e.g. conflict with - 8.3 "short" names. - Defaults to `true` on Windows, and `false` elsewhere. - -core.fsmonitor:: - If set, the value of this variable is used as a command which - will identify all files that may have changed since the - requested date/time. This information is used to speed up git by - avoiding unnecessary processing of files that have not changed. - See the "fsmonitor-watchman" section of linkgit:githooks[5]. - -core.trustctime:: - If false, the ctime differences between the index and the - working tree are ignored; useful when the inode change time - is regularly modified by something outside Git (file system - crawlers and some backup systems). - See linkgit:git-update-index[1]. True by default. - -core.splitIndex:: - If true, the split-index feature of the index will be used. - See linkgit:git-update-index[1]. False by default. - -core.untrackedCache:: - Determines what to do about the untracked cache feature of the - index. It will be kept, if this variable is unset or set to - `keep`. It will automatically be added if set to `true`. And - it will automatically be removed, if set to `false`. Before - setting it to `true`, you should check that mtime is working - properly on your system. - See linkgit:git-update-index[1]. `keep` by default. - -core.checkStat:: - When missing or is set to `default`, many fields in the stat - structure are checked to detect if a file has been modified - since Git looked at it. When this configuration variable is - set to `minimal`, sub-second part of mtime and ctime, the - uid and gid of the owner of the file, the inode number (and - the device number, if Git was compiled to use it), are - excluded from the check among these fields, leaving only the - whole-second part of mtime (and ctime, if `core.trustCtime` - is set) and the filesize to be checked. -+ -There are implementations of Git that do not leave usable values in -some fields (e.g. JGit); by excluding these fields from the -comparison, the `minimal` mode may help interoperability when the -same repository is used by these other systems at the same time. - -core.quotePath:: - Commands that output paths (e.g. 'ls-files', 'diff'), will - quote "unusual" characters in the pathname by enclosing the - pathname in double-quotes and escaping those characters with - backslashes in the same way C escapes control characters (e.g. - `\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with - values larger than 0x80 (e.g. octal `\302\265` for "micro" in - UTF-8). If this variable is set to false, bytes higher than - 0x80 are not considered "unusual" any more. Double-quotes, - backslash and control characters are always escaped regardless - of the setting of this variable. A simple space character is - not considered "unusual". Many commands can output pathnames - completely verbatim using the `-z` option. The default value - is true. - -core.eol:: - Sets the line ending type to use in the working directory for - files that have the `text` property set when core.autocrlf is false. - Alternatives are 'lf', 'crlf' and 'native', which uses the platform's - native line ending. The default value is `native`. See - linkgit:gitattributes[5] for more information on end-of-line - conversion. - -core.safecrlf:: - If true, makes Git check if converting `CRLF` is reversible when - end-of-line conversion is active. Git will verify if a command - modifies a file in the work tree either directly or indirectly. - For example, committing a file followed by checking out the - same file should yield the original file in the work tree. If - this is not the case for the current setting of - `core.autocrlf`, Git will reject the file. The variable can - be set to "warn", in which case Git will only warn about an - irreversible conversion but continue the operation. -+ -CRLF conversion bears a slight chance of corrupting data. -When it is enabled, Git will convert CRLF to LF during commit and LF to -CRLF during checkout. A file that contains a mixture of LF and -CRLF before the commit cannot be recreated by Git. For text -files this is the right thing to do: it corrects line endings -such that we have only LF line endings in the repository. -But for binary files that are accidentally classified as text the -conversion can corrupt data. -+ -If you recognize such corruption early you can easily fix it by -setting the conversion type explicitly in .gitattributes. Right -after committing you still have the original file in your work -tree and this file is not yet corrupted. You can explicitly tell -Git that this file is binary and Git will handle the file -appropriately. -+ -Unfortunately, the desired effect of cleaning up text files with -mixed line endings and the undesired effect of corrupting binary -files cannot be distinguished. In both cases CRLFs are removed -in an irreversible way. For text files this is the right thing -to do because CRLFs are line endings, while for binary files -converting CRLFs corrupts data. -+ -Note, this safety check does not mean that a checkout will generate a -file identical to the original file for a different setting of -`core.eol` and `core.autocrlf`, but only for the current one. For -example, a text file with `LF` would be accepted with `core.eol=lf` -and could later be checked out with `core.eol=crlf`, in which case the -resulting file would contain `CRLF`, although the original file -contained `LF`. However, in both work trees the line endings would be -consistent, that is either all `LF` or all `CRLF`, but never mixed. A -file with mixed line endings would be reported by the `core.safecrlf` -mechanism. - -core.autocrlf:: - Setting this variable to "true" is the same as setting - the `text` attribute to "auto" on all files and core.eol to "crlf". - Set to true if you want to have `CRLF` line endings in your - working directory and the repository has LF line endings. - This variable can be set to 'input', - in which case no output conversion is performed. - -core.checkRoundtripEncoding:: - A comma and/or whitespace separated list of encodings that Git - performs UTF-8 round trip checks on if they are used in an - `working-tree-encoding` attribute (see linkgit:gitattributes[5]). - The default value is `SHIFT-JIS`. - -core.symlinks:: - If false, symbolic links are checked out as small plain files that - contain the link text. linkgit:git-update-index[1] and - linkgit:git-add[1] will not change the recorded type to regular - file. Useful on filesystems like FAT that do not support - symbolic links. -+ -The default is true, except linkgit:git-clone[1] or linkgit:git-init[1] -will probe and set core.symlinks false if appropriate when the repository -is created. - -core.gitProxy:: - A "proxy command" to execute (as 'command host port') instead - of establishing direct connection to the remote server when - using the Git protocol for fetching. If the variable value is - in the "COMMAND for DOMAIN" format, the command is applied only - on hostnames ending with the specified domain string. This variable - may be set multiple times and is matched in the given order; - the first match wins. -+ -Can be overridden by the `GIT_PROXY_COMMAND` environment variable -(which always applies universally, without the special "for" -handling). -+ -The special string `none` can be used as the proxy command to -specify that no proxy be used for a given domain pattern. -This is useful for excluding servers inside a firewall from -proxy use, while defaulting to a common proxy for external domains. - -core.sshCommand:: - If this variable is set, `git fetch` and `git push` will - use the specified command instead of `ssh` when they need to - connect to a remote system. The command is in the same form as - the `GIT_SSH_COMMAND` environment variable and is overridden - when the environment variable is set. - -core.ignoreStat:: - If true, Git will avoid using lstat() calls to detect if files have - changed by setting the "assume-unchanged" bit for those tracked files - which it has updated identically in both the index and working tree. -+ -When files are modified outside of Git, the user will need to stage -the modified files explicitly (e.g. see 'Examples' section in -linkgit:git-update-index[1]). -Git will not normally detect changes to those files. -+ -This is useful on systems where lstat() calls are very slow, such as -CIFS/Microsoft Windows. -+ -False by default. - -core.preferSymlinkRefs:: - Instead of the default "symref" format for HEAD - and other symbolic reference files, use symbolic links. - This is sometimes needed to work with old scripts that - expect HEAD to be a symbolic link. - -core.alternateRefsCommand:: - When advertising tips of available history from an alternate, use the shell to - execute the specified command instead of linkgit:git-for-each-ref[1]. The - first argument is the absolute path of the alternate. Output must contain one - hex object id per line (i.e., the same as produce by `git for-each-ref - --format='%(objectname)'`). -+ -Note that you cannot generally put `git for-each-ref` directly into the config -value, as it does not take a repository path as an argument (but you can wrap -the command above in a shell script). - -core.alternateRefsPrefixes:: - When listing references from an alternate, list only references that begin - with the given prefix. Prefixes match as if they were given as arguments to - linkgit:git-for-each-ref[1]. To list multiple prefixes, separate them with - whitespace. If `core.alternateRefsCommand` is set, setting - `core.alternateRefsPrefixes` has no effect. - -core.bare:: - If true this repository is assumed to be 'bare' and has no - working directory associated with it. If this is the case a - number of commands that require a working directory will be - disabled, such as linkgit:git-add[1] or linkgit:git-merge[1]. -+ -This setting is automatically guessed by linkgit:git-clone[1] or -linkgit:git-init[1] when the repository was created. By default a -repository that ends in "/.git" is assumed to be not bare (bare = -false), while all other repositories are assumed to be bare (bare -= true). - -core.worktree:: - Set the path to the root of the working tree. - If `GIT_COMMON_DIR` environment variable is set, core.worktree - is ignored and not used for determining the root of working tree. - This can be overridden by the `GIT_WORK_TREE` environment - variable and the `--work-tree` command-line option. - The value can be an absolute path or relative to the path to - the .git directory, which is either specified by --git-dir - or GIT_DIR, or automatically discovered. - If --git-dir or GIT_DIR is specified but none of - --work-tree, GIT_WORK_TREE and core.worktree is specified, - the current working directory is regarded as the top level - of your working tree. -+ -Note that this variable is honored even when set in a configuration -file in a ".git" subdirectory of a directory and its value differs -from the latter directory (e.g. "/path/to/.git/config" has -core.worktree set to "/different/path"), which is most likely a -misconfiguration. Running Git commands in the "/path/to" directory will -still use "/different/path" as the root of the work tree and can cause -confusion unless you know what you are doing (e.g. you are creating a -read-only snapshot of the same index to a location different from the -repository's usual working tree). - -core.logAllRefUpdates:: - Enable the reflog. Updates to a ref is logged to the file - "`$GIT_DIR/logs/`", by appending the new and old - SHA-1, the date/time and the reason of the update, but - only when the file exists. If this configuration - variable is set to `true`, missing "`$GIT_DIR/logs/`" - file is automatically created for branch heads (i.e. under - `refs/heads/`), remote refs (i.e. under `refs/remotes/`), - note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`. - If it is set to `always`, then a missing reflog is automatically - created for any ref under `refs/`. -+ -This information can be used to determine what commit -was the tip of a branch "2 days ago". -+ -This value is true by default in a repository that has -a working directory associated with it, and false by -default in a bare repository. - -core.repositoryFormatVersion:: - Internal variable identifying the repository format and layout - version. - -core.sharedRepository:: - When 'group' (or 'true'), the repository is made shareable between - several users in a group (making sure all the files and objects are - group-writable). When 'all' (or 'world' or 'everybody'), the - repository will be readable by all users, additionally to being - group-shareable. When 'umask' (or 'false'), Git will use permissions - reported by umask(2). When '0xxx', where '0xxx' is an octal number, - files in the repository will have this mode value. '0xxx' will override - user's umask value (whereas the other options will only override - requested parts of the user's umask value). Examples: '0660' will make - the repo read/write-able for the owner and group, but inaccessible to - others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a - repository that is group-readable but not group-writable. - See linkgit:git-init[1]. False by default. - -core.warnAmbiguousRefs:: - If true, Git will warn you if the ref name you passed it is ambiguous - and might match multiple refs in the repository. True by default. - -core.compression:: - An integer -1..9, indicating a default compression level. - -1 is the zlib default. 0 means no compression, - and 1..9 are various speed/size tradeoffs, 9 being slowest. - If set, this provides a default to other compression variables, - such as `core.looseCompression` and `pack.compression`. - -core.looseCompression:: - An integer -1..9, indicating the compression level for objects that - are not in a pack file. -1 is the zlib default. 0 means no - compression, and 1..9 are various speed/size tradeoffs, 9 being - slowest. If not set, defaults to core.compression. If that is - not set, defaults to 1 (best speed). - -core.packedGitWindowSize:: - Number of bytes of a pack file to map into memory in a - single mapping operation. Larger window sizes may allow - your system to process a smaller number of large pack files - more quickly. Smaller window sizes will negatively affect - performance due to increased calls to the operating system's - memory manager, but may improve performance when accessing - a large number of large pack files. -+ -Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 -MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should -be reasonable for all users/operating systems. You probably do -not need to adjust this value. -+ -Common unit suffixes of 'k', 'm', or 'g' are supported. - -core.packedGitLimit:: - Maximum number of bytes to map simultaneously into memory - from pack files. If Git needs to access more than this many - bytes at once to complete an operation it will unmap existing - regions to reclaim virtual address space within the process. -+ -Default is 256 MiB on 32 bit platforms and 32 TiB (effectively -unlimited) on 64 bit platforms. -This should be reasonable for all users/operating systems, except on -the largest projects. You probably do not need to adjust this value. -+ -Common unit suffixes of 'k', 'm', or 'g' are supported. - -core.deltaBaseCacheLimit:: - Maximum number of bytes to reserve for caching base objects - that may be referenced by multiple deltified objects. By storing the - entire decompressed base objects in a cache Git is able - to avoid unpacking and decompressing frequently used base - objects multiple times. -+ -Default is 96 MiB on all platforms. This should be reasonable -for all users/operating systems, except on the largest projects. -You probably do not need to adjust this value. -+ -Common unit suffixes of 'k', 'm', or 'g' are supported. - -core.bigFileThreshold:: - Files larger than this size are stored deflated, without - attempting delta compression. Storing large files without - delta compression avoids excessive memory usage, at the - slight expense of increased disk usage. Additionally files - larger than this size are always treated as binary. -+ -Default is 512 MiB on all platforms. This should be reasonable -for most projects as source code and other text files can still -be delta compressed, but larger binary media files won't be. -+ -Common unit suffixes of 'k', 'm', or 'g' are supported. - -core.excludesFile:: - Specifies the pathname to the file that contains patterns to - describe paths that are not meant to be tracked, in addition - to '.gitignore' (per-directory) and '.git/info/exclude'. - Defaults to `$XDG_CONFIG_HOME/git/ignore`. - If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore` - is used instead. See linkgit:gitignore[5]. - -core.askPass:: - Some commands (e.g. svn and http interfaces) that interactively - ask for a password can be told to use an external program given - via the value of this variable. Can be overridden by the `GIT_ASKPASS` - environment variable. If not set, fall back to the value of the - `SSH_ASKPASS` environment variable or, failing that, a simple password - prompt. The external program shall be given a suitable prompt as - command-line argument and write the password on its STDOUT. - -core.attributesFile:: - In addition to '.gitattributes' (per-directory) and - '.git/info/attributes', Git looks into this file for attributes - (see linkgit:gitattributes[5]). Path expansions are made the same - way as for `core.excludesFile`. Its default value is - `$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not - set or empty, `$HOME/.config/git/attributes` is used instead. - -core.hooksPath:: - By default Git will look for your hooks in the - '$GIT_DIR/hooks' directory. Set this to different path, - e.g. '/etc/git/hooks', and Git will try to find your hooks in - that directory, e.g. '/etc/git/hooks/pre-receive' instead of - in '$GIT_DIR/hooks/pre-receive'. -+ -The path can be either absolute or relative. A relative path is -taken as relative to the directory where the hooks are run (see -the "DESCRIPTION" section of linkgit:githooks[5]). -+ -This configuration variable is useful in cases where you'd like to -centrally configure your Git hooks instead of configuring them on a -per-repository basis, or as a more flexible and centralized -alternative to having an `init.templateDir` where you've changed -default hooks. - -core.editor:: - Commands such as `commit` and `tag` that let you edit - messages by launching an editor use the value of this - variable when it is set, and the environment variable - `GIT_EDITOR` is not set. See linkgit:git-var[1]. - -core.commentChar:: - Commands such as `commit` and `tag` that let you edit - messages consider a line that begins with this character - commented, and removes them after the editor returns - (default '#'). -+ -If set to "auto", `git-commit` would select a character that is not -the beginning character of any line in existing commit messages. - -core.filesRefLockTimeout:: - The length of time, in milliseconds, to retry when trying to - lock an individual reference. Value 0 means not to retry at - all; -1 means to try indefinitely. Default is 100 (i.e., - retry for 100ms). - -core.packedRefsTimeout:: - The length of time, in milliseconds, to retry when trying to - lock the `packed-refs` file. Value 0 means not to retry at - all; -1 means to try indefinitely. Default is 1000 (i.e., - retry for 1 second). - -core.pager:: - Text viewer for use by Git commands (e.g., 'less'). The value - is meant to be interpreted by the shell. The order of preference - is the `$GIT_PAGER` environment variable, then `core.pager` - configuration, then `$PAGER`, and then the default chosen at - compile time (usually 'less'). -+ -When the `LESS` environment variable is unset, Git sets it to `FRX` -(if `LESS` environment variable is set, Git does not change it at -all). If you want to selectively override Git's default setting -for `LESS`, you can set `core.pager` to e.g. `less -S`. This will -be passed to the shell by Git, which will translate the final -command to `LESS=FRX less -S`. The environment does not set the -`S` option but the command line does, instructing less to truncate -long lines. Similarly, setting `core.pager` to `less -+F` will -deactivate the `F` option specified by the environment from the -command-line, deactivating the "quit if one screen" behavior of -`less`. One can specifically activate some flags for particular -commands: for example, setting `pager.blame` to `less -S` enables -line truncation only for `git blame`. -+ -Likewise, when the `LV` environment variable is unset, Git sets it -to `-c`. You can override this setting by exporting `LV` with -another value or setting `core.pager` to `lv +c`. - -core.whitespace:: - A comma separated list of common whitespace problems to - notice. 'git diff' will use `color.diff.whitespace` to - highlight them, and 'git apply --whitespace=error' will - consider them as errors. You can prefix `-` to disable - any of them (e.g. `-trailing-space`): -+ -* `blank-at-eol` treats trailing whitespaces at the end of the line - as an error (enabled by default). -* `space-before-tab` treats a space character that appears immediately - before a tab character in the initial indent part of the line as an - error (enabled by default). -* `indent-with-non-tab` treats a line that is indented with space - characters instead of the equivalent tabs as an error (not enabled by - default). -* `tab-in-indent` treats a tab character in the initial indent part of - the line as an error (not enabled by default). -* `blank-at-eof` treats blank lines added at the end of file as an error - (enabled by default). -* `trailing-space` is a short-hand to cover both `blank-at-eol` and - `blank-at-eof`. -* `cr-at-eol` treats a carriage-return at the end of line as - part of the line terminator, i.e. with it, `trailing-space` - does not trigger if the character before such a carriage-return - is not a whitespace (not enabled by default). -* `tabwidth=` tells how many character positions a tab occupies; this - is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent` - errors. The default tab width is 8. Allowed values are 1 to 63. - -core.fsyncObjectFiles:: - This boolean will enable 'fsync()' when writing object files. -+ -This is a total waste of time and effort on a filesystem that orders -data writes properly, but can be useful for filesystems that do not use -journalling (traditional UNIX filesystems) or that only journal metadata -and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback"). - -core.preloadIndex:: - Enable parallel index preload for operations like 'git diff' -+ -This can speed up operations like 'git diff' and 'git status' especially -on filesystems like NFS that have weak caching semantics and thus -relatively high IO latencies. When enabled, Git will do the -index comparison to the filesystem data in parallel, allowing -overlapping IO's. Defaults to true. - -core.createObject:: - You can set this to 'link', in which case a hardlink followed by - a delete of the source are used to make sure that object creation - will not overwrite existing objects. -+ -On some file system/operating system combinations, this is unreliable. -Set this config setting to 'rename' there; However, This will remove the -check that makes sure that existing object files will not get overwritten. - -core.notesRef:: - When showing commit messages, also show notes which are stored in - the given ref. The ref must be fully qualified. If the given - ref does not exist, it is not an error but means that no - notes should be printed. -+ -This setting defaults to "refs/notes/commits", and it can be overridden by -the `GIT_NOTES_REF` environment variable. See linkgit:git-notes[1]. - -core.commitGraph:: - If true, then git will read the commit-graph file (if it exists) - to parse the graph structure of commits. Defaults to false. See - linkgit:git-commit-graph[1] for more information. - -core.useReplaceRefs:: - If set to `false`, behave as if the `--no-replace-objects` - option was given on the command line. See linkgit:git[1] and - linkgit:git-replace[1] for more information. - -core.multiPackIndex:: - Use the multi-pack-index file to track multiple packfiles using a - single index. See link:technical/multi-pack-index.html[the - multi-pack-index design document]. - -core.sparseCheckout:: - Enable "sparse checkout" feature. See section "Sparse checkout" in - linkgit:git-read-tree[1] for more information. - -core.abbrev:: - Set the length object names are abbreviated to. If - unspecified or set to "auto", an appropriate value is - computed based on the approximate number of packed objects - in your repository, which hopefully is enough for - abbreviated object names to stay unique for some time. - The minimum length is 4. +include::config/core.txt[] add.ignoreErrors:: add.ignore-errors (deprecated):: diff --git a/Documentation/config/core.txt b/Documentation/config/core.txt new file mode 100644 index 0000000000..73430b635b --- /dev/null +++ b/Documentation/config/core.txt @@ -0,0 +1,594 @@ +core.fileMode:: + Tells Git if the executable bit of files in the working tree + is to be honored. ++ +Some filesystems lose the executable bit when a file that is +marked as executable is checked out, or checks out a +non-executable file with executable bit on. +linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem +to see if it handles the executable bit correctly +and this variable is automatically set as necessary. ++ +A repository, however, may be on a filesystem that handles +the filemode correctly, and this variable is set to 'true' +when created, but later may be made accessible from another +environment that loses the filemode (e.g. exporting ext4 via +CIFS mount, visiting a Cygwin created repository with +Git for Windows or Eclipse). +In such a case it may be necessary to set this variable to 'false'. +See linkgit:git-update-index[1]. ++ +The default is true (when core.filemode is not specified in the config file). + +core.hideDotFiles:: + (Windows-only) If true, mark newly-created directories and files whose + name starts with a dot as hidden.

Modifying this value may result in unexpected behavior. + +core.precomposeUnicode:: + This option is only used by Mac OS implementation of Git. + When core.precomposeUnicode=true, Git reverts the unicode decomposition + of filenames done by Mac OS. This is useful when sharing a repository + between Mac OS and Linux or Windows. + (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). + When false, file names are handled fully transparent by Git, + which is backward compatible with older versions of Git. + +core.protectHFS:: + If set to true, do not allow checkout of paths that would + be considered equivalent to `.git` on an HFS+ filesystem. + Defaults to `true` on Mac OS, and `false` elsewhere. + +core.protectNTFS:: + If set to true, do not allow checkout of paths that would + cause problems with the NTFS filesystem, e.g. conflict with + 8.3 "short" names. + Defaults to `true` on Windows, and `false` elsewhere. + +core.fsmonitor:: + If set, the value of this variable is used as a command which + will identify all files that may have changed since the + requested date/time. This information is used to speed up git by + avoiding unnecessary processing of files that have not changed. + See the "fsmonitor-watchman" section of linkgit:githooks[5]. + +core.trustctime:: + If false, the ctime differences between the index and the + working tree are ignored; useful when the inode change time + is regularly modified by something outside Git (file system + crawlers and some backup systems). + See linkgit:git-update-index[1].

Before + setting it to `true`, you should check that mtime is working + properly on your system. + See linkgit:git-update-index[1]. `keep` by default. + +core.checkStat:: + When missing or is set to `default`, many fields in the stat + structure are checked to detect if a file has been modified + since Git looked at it. When this configuration variable is + set to `minimal`, sub-second part of mtime and ctime, the + uid and gid of the owner of the file, the inode number (and + the device number, if Git was compiled to use it), are + excluded from the check among these fields, leaving only the + whole-second part of mtime (and ctime, if `core.trustCtime` + is set) and the filesize to be checked. ++ +There are implementations of Git that do not leave usable values in +some fields (e.g. JGit); by excluding these fields from the +comparison, the `minimal` mode may help interoperability when the +same repository is used by these other systems at the same time. + +core.quotePath:: + Commands that output paths (e.g. 'ls-files', 'diff'), will + quote "unusual" characters in the pathname by enclosing the + pathname in double-quotes and escaping those characters with + backslashes in the same way C escapes control characters (e.g. + `\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with + values larger than 0x80 (e.g. octal `\302\265` for "micro" in + UTF-8). If this variable is set to false, bytes higher than + 0x80 are not considered "unusual" any more. Double-quotes, + backslash and control characters are always escaped regardless + of the setting of this variable. A simple space character is + not considered "unusual". Many commands can output pathnames + completely verbatim using the `-z` option. The default value + is true. + +core.eol:: + Sets the line ending type to use in the working directory for + files that have the `text` property set when core.autocrlf is false. + Alternatives are 'lf', 'crlf' and 'native', which uses the platform's + native line ending. The default value is `native`. See + linkgit:gitattributes[5] for more information on end-of-line + conversion. + +core.safecrlf:: + If true, makes Git check if converting `CRLF` is reversible when + end-of-line conversion is active. Git will verify if a command + modifies a file in the work tree either directly or indirectly. + For example, committing a file followed by checking out the + same file should yield the original file in the work tree. If + this is not the case for the current setting of + `core.autocrlf`, Git will reject the file. The variable can + be set to "warn", in which case Git will only warn about an + irreversible conversion but continue the operation. ++ +CRLF conversion bears a slight chance of corrupting data. +When it is enabled, Git will convert CRLF to LF during commit and LF to +CRLF during checkout. A file that contains a mixture of LF and +CRLF before the commit cannot be recreated by Git. For text +files this is the right thing to do: it corrects line endings +such that we have only LF line endings in the repository. +But for binary files that are accidentally classified as text the +conversion can corrupt data. ++ +If you recognize such corruption early you can easily fix it by +setting the conversion type explicitly in .gitattributes. Right +after committing you still have the original file in your work +tree and this file is not yet corrupted. You can explicitly tell +Git that this file is binary and Git will handle the file +appropriately. ++ +Unfortunately, the desired effect of cleaning up text files with +mixed line endings and the undesired effect of corrupting binary +files cannot be distinguished. In both cases CRLFs are removed +in an irreversible way. For text files this is the right thing +to do because CRLFs are line endings, while for binary files +converting CRLFs corrupts data. ++ +Note, this safety check does not mean that a checkout will generate a +file identical to the original file for a different setting of +`core.eol` and `core.autocrlf`, but only for the current one. For +example, a text file with `LF` would be accepted with `core.eol=lf` +and could later be checked out with `core.eol=crlf`, in which case the +resulting file would contain `CRLF`, although the original file +contained `LF`. However, in both work trees the line endings would be +consistent, that is either all `LF` or all `CRLF`, but never mixed. A +file with mixed line endings would be reported by the `core.safecrlf` +mechanism. + +core.autocrlf:: + Setting this variable to "true" is the same as setting + the `text` attribute to "auto" on all files and core.eol to "crlf". + Set to true if you want to have `CRLF` line endings in your + working directory and the repository has LF line endings. + This variable can be set to 'input', + in which case no output conversion is performed. + +core.checkRoundtripEncoding:: + A comma and/or whitespace separated list of encodings that Git + performs UTF-8 round trip checks on if they are used in an + `working-tree-encoding` attribute (see linkgit:gitattributes[5]). + The default value is `SHIFT-JIS`. + +core.symlinks:: + If false, symbolic links are checked out as small plain files that + contain the link text. linkgit:git-update-index[1] and + linkgit:git-add[1] will not change the recorded type to regular + file. Useful on filesystems like FAT that do not support + symbolic links. ++ +The default is true, except linkgit:git-clone[1] or linkgit:git-init[1] +will probe and set core.symlinks false if appropriate when the repository +is created. + +core.gitProxy:: + A "proxy command" to execute (as 'command host port') instead + of establishing direct connection to the remote server when + using the Git protocol for fetching. If the variable value is + in the "COMMAND for DOMAIN" format, the command is applied only + on hostnames ending with the specified domain string. This variable + may be set multiple times and is matched in the given order; + the first match wins. ++ +Can be overridden by the `GIT_PROXY_COMMAND` environment variable +(which always applies universally, without the special "for" +handling). ++ +The special string `none` can be used as the proxy command to +specify that no proxy be used for a given domain pattern. +This is useful for excluding servers inside a firewall from +proxy use, while defaulting to a common proxy for external domains. + +core.sshCommand:: + If this variable is set, `git fetch` and `git push` will + use the specified command instead of `ssh` when they need to + connect to a remote system. The command is in the same form as + the `GIT_SSH_COMMAND` environment variable and is overridden + when the environment variable is set. + +core.ignoreStat:: + If true, Git will avoid using lstat() calls to detect if files have + changed by setting the "assume-unchanged" bit for those tracked files + which it has updated identically in both the index and working tree. ++ +When files are modified outside of Git, the user will need to stage +the modified files explicitly (e.g. see 'Examples' section in +linkgit:git-update-index[1]). +Git will not normally detect changes to those files. ++ +This is useful on systems where lstat() calls are very slow, such as +CIFS/Microsoft Windows. ++ +False by default. + +core.preferSymlinkRefs:: + Instead of the default "symref" format for HEAD + and other symbolic reference files, use symbolic links. + This is sometimes needed to work with old scripts that + expect HEAD to be a symbolic link. + +core.alternateRefsCommand:: + When advertising tips of available history from an alternate, use the shell to + execute the specified command instead of linkgit:git-for-each-ref[1]. The + first argument is the absolute path of the alternate. Output must contain one + hex object id per line (i.e., the same as produce by `git for-each-ref + --format='%(objectname)'`). ++ +Note that you cannot generally put `git for-each-ref` directly into the config +value, as it does not take a repository path as an argument (but you can wrap +the command above in a shell script). + +core.alternateRefsPrefixes:: + When listing references from an alternate, list only references that begin + with the given prefix. Prefixes match as if they were given as arguments to + linkgit:git-for-each-ref[1]. To list multiple prefixes, separate them with + whitespace. If `core.alternateRefsCommand` is set, setting + `core.alternateRefsPrefixes` has no effect. + +core.bare:: + If true this repository is assumed to be 'bare' and has no + working directory associated with it. If this is the case a + number of commands that require a working directory will be + disabled, such as linkgit:git-add[1] or linkgit:git-merge[1]. ++ +This setting is automatically guessed by linkgit:git-clone[1] or +linkgit:git-init[1] when the repository was created. By default a +repository that ends in "/.git" is assumed to be not bare (bare = +false), while all other repositories are assumed to be bare (bare += true). + +core.worktree:: + Set the path to the root of the working tree. + If `GIT_COMMON_DIR` environment variable is set, core.worktree + is ignored and not used for determining the root of working tree. + This can be overridden by the `GIT_WORK_TREE` environment + variable and the `--work-tree` command-line option. + The value can be an absolute path or relative to the path to + the .git directory, which is either specified by --git-dir + or GIT_DIR, or automatically discovered. + If --git-dir or GIT_DIR is specified but none of + --work-tree, GIT_WORK_TREE and core.worktree is specified, + the current working directory is regarded as the top level + of your working tree. ++ +Note that this variable is honored even when set in a configuration +file in a ".git" subdirectory of a directory and its value differs +from the latter directory (e.g. "/path/to/.git/config" has +core.worktree set to "/different/path"), which is most likely a +misconfiguration. Running Git commands in the "/path/to" directory will +still use "/different/path" as the root of the work tree and can cause +confusion unless you know what you are doing (e.g. you are creating a +read-only snapshot of the same index to a location different from the +repository's usual working tree). + +core.logAllRefUpdates:: + Enable the reflog. Updates to a ref is logged to the file + "`$GIT_DIR/logs/`", by appending the new and old + SHA-1, the date/time and the reason of the update, but + only when the file exists. If this configuration + variable is set to `true`, missing "`$GIT_DIR/logs/`" + file is automatically created for branch heads (i.e. under + `refs/heads/`), remote refs (i.e. under `refs/remotes/`), + note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`. + If it is set to `always`, then a missing reflog is automatically + created for any ref under `refs/`. ++ +This information can be used to determine what commit +was the tip of a branch "2 days ago". ++ +This value is true by default in a repository that has +a working directory associated with it, and false by +default in a bare repository. + +core.repositoryFormatVersion:: + Internal variable identifying the repository format and layout + version. + +core.sharedRepository:: + When 'group' (or 'true'), the repository is made shareable between + several users in a group (making sure all the files and objects are + group-writable). When 'all' (or 'world' or 'everybody'), the + repository will be readable by all users, additionally to being + group-shareable. When 'umask' (or 'false'), Git will use permissions + reported by umask(2). When '0xxx', where '0xxx' is an octal number, + files in the repository will have this mode value. '0xxx' will override + user's umask value (whereas the other options will only override + requested parts of the user's umask value). Examples: '0660' will make + the repo read/write-able for the owner and group, but inaccessible to + others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a + repository that is group-readable but not group-writable. + See linkgit:git-init[1]. False by default. + +core.warnAmbiguousRefs:: + If true, Git will warn you if the ref name you passed it is ambiguous + and might match multiple refs in the repository. True by default. + +core.compression:: + An integer -1..9, indicating a default compression level. + -1 is the zlib default. 0 means no compression, + and 1..9 are various speed/size tradeoffs, 9 being slowest. + If set, this provides a default to other compression variables, + such as `core.looseCompression` and `pack.compression`. + +core.looseCompression:: + An integer -1..9, indicating the compression level for objects that + are not in a pack file. -1 is the zlib default. 0 means no + compression, and 1..9 are various speed/size tradeoffs, 9 being + slowest. If not set, defaults to core.compression. If that is + not set, defaults to 1 (best speed). + +core.packedGitWindowSize:: + Number of bytes of a pack file to map into memory in a + single mapping operation. Larger window sizes may allow + your system to process a smaller number of large pack files + more quickly. Smaller window sizes will negatively affect + performance due to increased calls to the operating system's + memory manager, but may improve performance when accessing + a large number of large pack files. ++ +Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 +MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should +be reasonable for all users/operating systems. You probably do +not need to adjust this value. ++ +Common unit suffixes of 'k', 'm', or 'g' are supported. + +core.packedGitLimit:: + Maximum number of bytes to map simultaneously into memory + from pack files. If Git needs to access more than this many + bytes at once to complete an operation it will unmap existing + regions to reclaim virtual address space within the process. ++ +Default is 256 MiB on 32 bit platforms and 32 TiB (effectively +unlimited) on 64 bit platforms. +This should be reasonable for all users/operating systems, except on +the largest projects. You probably do not need to adjust this value. ++ +Common unit suffixes of 'k', 'm', or 'g' are supported. + +core.deltaBaseCacheLimit:: + Maximum number of bytes to reserve for caching base objects + that may be referenced by multiple deltified objects. By storing the + entire decompressed base objects in a cache Git is able + to avoid unpacking and decompressing frequently used base + objects multiple times. ++ +Default is 96 MiB on all platforms. This should be reasonable +for all users/operating systems, except on the largest projects. +You probably do not need to adjust this value. ++ +Common unit suffixes of 'k', 'm', or 'g' are supported. + +core.bigFileThreshold:: + Files larger than this size are stored deflated, without + attempting delta compression. Storing large files without + delta compression avoids excessive memory usage, at the + slight expense of increased disk usage. Additionally files + larger than this size are always treated as binary. ++ +Default is 512 MiB on all platforms. This should be reasonable +for most projects as source code and other text files can still +be delta compressed, but larger binary media files won't be. ++ +Common unit suffixes of 'k', 'm', or 'g' are supported. + +core.excludesFile:: + Specifies the pathname to the file that contains patterns to + describe paths that are not meant to be tracked, in addition + to '.gitignore' (per-directory) and '.git/info/exclude'. + Defaults to `$XDG_CONFIG_HOME/git/ignore`. + If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore` + is used instead. See linkgit:gitignore[5]. + +core.askPass:: + Some commands (e.g. svn and http interfaces) that interactively + ask for a password can be told to use an external program given + via the value of this variable. Can be overridden by the `GIT_ASKPASS` + environment variable. If not set, fall back to the value of the + `SSH_ASKPASS` environment variable or, failing that, a simple password + prompt. The external program shall be given a suitable prompt as + command-line argument and write the password on its STDOUT. + +core.attributesFile:: + In addition to '.gitattributes' (per-directory) and + '.git/info/attributes', Git looks into this file for attributes + (see linkgit:gitattributes[5]). Path expansions are made the same + way as for `core.excludesFile`. Its default value is + `$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not + set or empty, `$HOME/.config/git/attributes` is used instead. + +core.hooksPath:: + By default Git will look for your hooks in the + '$GIT_DIR/hooks' directory. Set this to different path, + e.g. '/etc/git/hooks', and Git will try to find your hooks in + that directory, e.g. '/etc/git/hooks/pre-receive' instead of + in '$GIT_DIR/hooks/pre-receive'. ++ +The path can be either absolute or relative. A relative path is +taken as relative to the directory where the hooks are run (see +the "DESCRIPTION" section of linkgit:githooks[5]). ++ +This configuration variable is useful in cases where you'd like to +centrally configure your Git hooks instead of configuring them on a +per-repository basis, or as a more flexible and centralized +alternative to having an `init.templateDir` where you've changed +default hooks. + +core.editor:: + Commands such as `commit` and `tag` that let you edit + messages by launching an editor use the value of this + variable when it is set, and the environment variable + `GIT_EDITOR` is not set. See linkgit:git-var[1]. + +core.commentChar:: + Commands such as `commit` and `tag` that let you edit + messages consider a line that begins with this character + commented, and removes them after the editor returns + (default '#'). ++ +If set to "auto", `git-commit` would select a character that is not +the beginning character of any line in existing commit messages. + +core.filesRefLockTimeout:: + The length of time, in milliseconds, to retry when trying to + lock an individual reference. Value 0 means not to retry at + all; -1 means to try indefinitely. Default is 100 (i.e., + retry for 100ms). + +core.packedRefsTimeout:: + The length of time, in milliseconds, to retry when trying to + lock the `packed-refs` file. Value 0 means not to retry at + all; -1 means to try indefinitely. Default is 1000 (i.e., + retry for 1 second). + +core.pager:: + Text viewer for use by Git commands (e.g., 'less'). The value + is meant to be interpreted by the shell. The order of preference + is the `$GIT_PAGER` environment variable, then `core.pager` + configuration, then `$PAGER`, and then the default chosen at + compile time (usually 'less'). ++ +When the `LESS` environment variable is unset, Git sets it to `FRX` +(if `LESS` environment variable is set, Git does not change it at +all). If you want to selectively override Git's default setting +for `LESS`, you can set `core.pager` to e.g. `less -S`. This will +be passed to the shell by Git, which will translate the final +command to `LESS=FRX less -S`. The environment does not set the +`S` option but the command line does, instructing less to truncate +long lines. Similarly, setting `core.pager` to `less -+F` will +deactivate the `F` option specified by the environment from the +command-line, deactivating the "quit if one screen" behavior of +`less`. One can specifically activate some flags for particular +commands: for example, setting `pager.blame` to `less -S` enables +line truncation only for `git blame`. ++ +Likewise, when the `LV` environment variable is unset, Git sets it +to `-c`. You can override this setting by exporting `LV` with +another value or setting `core.pager` to `lv +c`. + +core.whitespace:: + A comma separated list of common whitespace problems to + notice. 'git diff' will use `color.diff.whitespace` to + highlight them, and 'git apply --whitespace=error' will + consider them as errors. You can prefix `-` to disable + any of them (e.g. `-trailing-space`): ++ +* `blank-at-eol` treats trailing whitespaces at the end of the line + as an error (enabled by default). +* `space-before-tab` treats a space character that appears immediately + before a tab character in the initial indent part of the line as an + error (enabled by default). +* `indent-with-non-tab` treats a line that is indented with space + characters instead of the equivalent tabs as an error (not enabled by + default). +* `tab-in-indent` treats a tab character in the initial indent part of + the line as an error (not enabled by default). +* `blank-at-eof` treats blank lines added at the end of file as an error + (enabled by default). +* `trailing-space` is a short-hand to cover both `blank-at-eol` and + `blank-at-eof`. +* `cr-at-eol` treats a carriage-return at the end of line as + part of the line terminator, i.e. with it, `trailing-space` + does not trigger if the character before such a carriage-return + is not a whitespace (not enabled by default). +* `tabwidth=` tells how many character positions a tab occupies; this + is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent` + errors. The default tab width is 8. Allowed values are 1 to 63. + +core.fsyncObjectFiles:: + This boolean will enable 'fsync()' when writing object files. ++ +This is a total waste of time and effort on a filesystem that orders +data writes properly, but can be useful for filesystems that do not use +journalling (traditional UNIX filesystems) or that only journal metadata +and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback"). + +core.preloadIndex:: + Enable parallel index preload for operations like 'git diff' ++ +This can speed up operations like 'git diff' and 'git status' especially +on filesystems like NFS that have weak caching semantics and thus +relatively high IO latencies. When enabled, Git will do the +index comparison to the filesystem data in parallel, allowing +overlapping IO's. Defaults to true. + +core.createObject:: + You can set this to 'link', in which case a hardlink followed by + a delete of the source are used to make sure that object creation + will not overwrite existing objects. ++ +On some file system/operating system combinations, this is unreliable. +Set this config setting to 'rename' there; However, This will remove the +check that makes sure that existing object files will not get overwritten. + +core.notesRef:: + When showing commit messages, also show notes which are stored in + the given ref. The ref must be fully qualified. If the given + ref does not exist, it is not an error but means that no + notes should be printed. ++ +This setting defaults to "refs/notes/commits", and it can be overridden by +the `GIT_NOTES_REF` environment variable. See linkgit:git-notes[1]. + +core.commitGraph:: + If true, then git will read the commit-graph file (if it exists) + to parse the graph structure of commits. Defaults to false. See + linkgit:git-commit-graph[1] for more information. + +core.useReplaceRefs:: + If set to `false`, behave as if the `--no-replace-objects` + option was given on the command line. See linkgit:git[1] and + linkgit:git-replace[1] for more information. + +core.multiPackIndex:: + Use the multi-pack-index file to track multiple packfiles using a + single index. See link:technical/multi-pack-index.html[the + multi-pack-index design document]. + +core.sparseCheckout:: + Enable "sparse checkout" feature. See section "Sparse checkout" in + linkgit:git-read-tree[1] for more information. + +core.abbrev:: + Set the length object names are abbreviated to. If + unspecified or set to "auto", an appropriate value is + computed based on the approximate number of packed objects + in your repository, which hopefully is enough for + abbreviated object names to stay unique for some time. + The minimum length is 4.
