git-lfs-config(5) -- Configuration options for git-lfs
======================================================

## CONFIGURATION FILES

git-lfs reads its configuration from a file called `.lfsconfig` at the root of
the repository. The `.lfsconfig` file uses the same format as `.gitconfig`.

Additionally, all settings can be overridden by values returned by `git config -l`.
This allows you to override settings like `lfs.url` in your local environment
without having to modify the `.lfsconfig` file.

Most options regarding git-lfs are contained in the `[lfs]` section, meaning
they are all named `lfs.foo` or similar, although occasionally an lfs option can
be scoped inside the configuration for a remote.


## LIST OF OPTIONS

### General settings

* `lfs.url` / `remote.<remote>.lfsurl`

  The url used to call the Git LFS remote API. Default blank (derive from clone
  URL).

* `lfs.pushurl` / `remote.<remote>.lfspushurl`

  The url used to call the Git LFS remote API when pushing. Default blank (derive
  from either LFS non-push urls or clone url).

* `lfs.dialtimeout`

  Sets the maximum time, in seconds, that the HTTP client will wait to initiate
  a connection. This does not include the time to send a request and wait for a
  response. Default: 30 seconds

* `lfs.tlstimeout`

  Sets the maximum time, in seconds, that the HTTP client will wait for a TLS
  handshake. Default: 30 seconds.

* `lfs.activitytimeout` / `lfs.https://<host>.activitytimeout`

  Sets the maximum time, in seconds, that the HTTP client will wait for the
  next tcp read or write. If < 1, no activity timeout is used at all.
  Default: 30 seconds

* `lfs.keepalive`

  Sets the maximum time, in seconds, for the HTTP client to maintain keepalive
  connections. Default: 30 minutes.

* `lfs.ssh.retries`

  Specifies the number of times Git LFS will attempt to obtain authorization via
  SSH before aborting. Default: 5.

* `core.askpass`, GIT_ASKPASS

  Given as a program and its arguments, this is invoked when authentication is
  needed against the LFS API. The contents of stdout are interpreted as the
  password.

* `lfs.cachecredentials`

  Enables in-memory SSH and Git Credential caching for a single 'git lfs'
  command. Default: enabled.

* `lfs.storage`

  Allow override LFS storage directory. Non-absolute path is relativized to
  inside of Git repository directory (usually `.git`).

  Note: you should not run `git lfs prune` if you have different repositories
  sharing the same storage directory.

  Default: `lfs` in Git repository directory (usually `.git/lfs`).

### Transfer (upload / download) settings

  These settings control how the upload and download of LFS content occurs.

* `lfs.concurrenttransfers`

  The number of concurrent uploads/downloads. Default 8.

* `lfs.basictransfersonly`

  If set to true, only basic HTTP upload/download transfers will be used,
  ignoring any more advanced transfers that the client/server may support.
  This is primarily to work around bugs or incompatibilities.

  The git-lfs client supports basic HTTP downloads, resumable HTTP downloads
  (using `Range` headers), and resumable uploads via tus.io protocol. Custom
  transfer methods can be added via `lfs.customtransfer` (see next section).
  However setting this value to true limits the client to simple HTTP.

* `lfs.tustransfers`

  If set to true, this enables resumable uploads of LFS objects through the
  tus.io API. Once this feature is finalized, this setting will be removed,
  and tus.io uploads will be available for all clients.

* `lfs.standalonetransferagent`

  Allows the specified custom transfer agent to be used directly
  for transferring files, without asking the server how the transfers
  should be made. The custom transfer agent has to be defined in a
  `lfs.customtransfer.<name>` settings group.

* `lfs.customtransfer.<name>.path`

  `lfs.customtransfer.<name>` is a settings group which defines a custom
  transfer hook which allows you to upload/download via an intermediate process,
  using any mechanism you like (rather than just HTTP). `path` should point to
  the process you wish to invoke. The protocol between the git-lfs client and
  the custom transfer process is documented at
  https://github.com/git-lfs/git-lfs/blob/master/docs/custom-transfers.md

  <name> must be a unique identifier that the LFS server understands. When
  calling the LFS API the client will include a list of supported transfer
  types. If the server also supports this named transfer type, it will select it
  and actions returned from the API will be in relation to that transfer type
  (may not be traditional URLs for example). Only if the server accepts <name>
  as a transfer it supports will this custom transfer process be invoked.

* `lfs.customtransfer.<name>.args`

  If the custom transfer process requires any arguments, these can be provided
  here.  This string will be expanded by the shell.

* `lfs.customtransfer.<name>.concurrent`

  If true (the default), git-lfs will invoke the custom transfer process
  multiple times in parallel, according to `lfs.concurrenttransfers`, splitting
  the transfer workload between the processes.

* `lfs.customtransfer.<name>.direction`

  Specifies which direction the custom transfer process supports, either
  "download", "upload", or "both". The default if unspecified is "both".

* `lfs.transfer.maxretries`

  Specifies how many retries LFS will attempt per OID before marking the
  transfer as failed. Must be an integer which is at least one. If the value is
  not an integer, is less than one, or is not given, a value of eight will be
  used instead.

* `lfs.transfer.maxverifies`

  Specifies how many verification requests LFS will attempt per OID before
  marking the transfer as failed, if the object has a verification action
  associated with it. Must be an integer which is at least one. If the value is
  not an integer, is less than one, or is not given, a default value of three
  will be used instead.

### Push settings

* `lfs.allowincompletepush`

  When pushing, allow objects to be missing from the local cache without halting
  a Git push. Default: false.

### Fetch settings

* `lfs.fetchinclude`

  When fetching, only download objects which match any entry on this
  comma-separated list of paths/filenames. Wildcard matching is as per
  git-ignore(1). See git-lfs-fetch(1) for examples.

* `lfs.fetchexclude`

  When fetching, do not download objects which match any item on this
  comma-separated list of paths/filenames. Wildcard matching is as per
  git-ignore(1). See git-lfs-fetch(1) for examples.

* `lfs.fetchrecentrefsdays`

  If non-zero, fetches refs which have commits within N days of the current
  date. Only local refs are included unless lfs.fetchrecentremoterefs is true.
  Also used as a basis for pruning old files.
  The default is 7 days.

* `lfs.fetchrecentremoterefs`

  If true, fetches remote refs (for the remote you're fetching) as well as local
  refs in the recent window. This is useful to fetch objects for remote branches
  you might want to check out later. The default is true; if you set this to
  false, fetching for those branches will only occur when you either check them
  out (losing the advantage of fetch --recent), or create a tracking local
  branch separately then fetch again.

* `lfs.fetchrecentcommitsdays`

  In addition to fetching at refs, also fetches previous changes made within N
  days of the latest commit on the ref. This is useful if you're often reviewing
  recent changes.   Also used as a basis for pruning old files.
  The default is 0 (no previous changes).

* `lfs.fetchrecentalways`

  Always operate as if --recent was included in a `git lfs fetch` call. Default
  false.

### Prune settings

* `lfs.pruneoffsetdays`

  The number of days added to the `lfs.fetchrecent*` settings to determine what
  can be pruned. Default is 3 days, i.e. that anything fetched at the very
  oldest edge of the 'recent window' is eligible for pruning 3 days later.

* `lfs.pruneremotetocheck`

  Set the remote that LFS files must have been pushed to in order for them to
  be considered eligible for local pruning. Also the remote which is called if
  --verify-remote is enabled.

* `lfs.pruneverifyremotealways`

  Always run `git lfs prune` as if `--verify-remote` was provided.

### Extensions

* `lfs.extension.<name>.<setting>`

  Git LFS extensions enable the manipulation of files streams during smudge and
  clean. `name` groups the settings for a single extension, and the settings
  are:
  * `clean` The command which runs when files are added to the index
  * `smudge` The command which runs when files are written to the working copy
  * `priority` The order of this extension compared to others

### Other settings

* `lfs.<url>.access`

  Note: this setting is normally set by LFS itself on receiving a 401 response
  (authentication required), you don't normally need to set it manually.

  If set to "basic" then credentials will be requested before making batch
  requests to this url, otherwise a public request will initially be attempted.

* `lfs.<url>.locksverify`

  Determines whether locks are checked before Git pushes. This prevents you from
  pushing changes to files that other users have locked. The Git LFS pre-push
  hook varies its behavior based on the value of this config key.

  * `null` - In the absence of a value, Git LFS will attempt the call, and warn
  if it returns an error. If the response is valid, Git LFS will set the value
  to `true`, and will halt the push if the user attempts to update a file locked
  by another user. If the server returns a `501 Not Implemented` response, Git
  LFS will set the value to `false.`
  * `true` - Git LFS will attempt to verify locks, halting the Git push if there
  are any server issues, or if the user attempts to update a file locked by
  another user.
  * `false` - Git LFS will completely skip the lock check in the pre-push hook.
  You should set this if you're not using File Locking, or your Git server
  verifies locked files on pushes automatically.

  Supports URL config lookup as described in:
  https://git-scm.com/docs/git-config#git-config-httplturlgt. To set this value
  per-host: `git config --global lfs.https://github.com/.locksverify [true|false]`.

* `lfs.<url>.contenttype`

  Determines whether Git LFS should attempt to detect an appropriate HTTP
  `Content-Type` header when uploading using the 'basic' upload adapter. If set
  to false, the default header of `Content-Type: application/octet-stream` is
  chosen instead. Default: 'true'.

* `lfs.skipdownloaderrors`

  Causes Git LFS not to abort the smudge filter when a download error is
  encountered, which allows actions such as checkout to work when you are unable
  to download the LFS content. LFS files which could not download will contain
  pointer content instead.

  Note that this will result in git commands which call the smudge filter to
  report success even in cases when LFS downloads fail, which may affect
  scripts.

  You can also set the environment variable GIT_LFS_SKIP_DOWNLOAD_ERRORS=1 to
  get the same effect.

* `GIT_LFS_PROGRESS`

  This environment variable causes Git LFS to emit progress updates to an
  absolute file-path on disk when cleaning, smudging, or fetching.

  Progress is reported periodically in the form of a new line being appended to
  the end of the file. Each new line will take the following format:

  `<direction> <current>/<total files> <downloaded>/<total> <name>`

  Each field is described below:
  * `direction`: The direction of transfer, either "checkout", "download", or
    "upload".
  * `current` The index of the currently transferring file.
  * `total files` The estimated count of all files to be transferred.
  * `downloaded` The number of bytes already downloaded.
  * `total` The entire size of the file, in bytes.
  * `name` The name of the file.

* `GIT_LFS_SET_LOCKABLE_READONLY`
  `lfs.setlockablereadonly`

  These settings, the first an environment variable and the second a gitconfig
  setting, control whether files marked as 'lockable' in `git lfs track` are
  made read-only in the working copy when not locked by the current user.
  The default is `true`; you can disable this behaviour and have all files
  writeable by setting either variable to 0, 'no' or 'false'.

* `lfs.defaulttokenttl`

  This setting sets a default token TTL when git-lfs-authenticate does not
  include the TTL in the JSON response but still enforces it.

  Note that this is only necessary for larger repositories hosted on LFS
  servers that don't include the TTL.

## LFSCONFIG

The .lfsconfig file in a repository is read and interpreted in the same format
as the file stored in .git/config. It allows a subset of keys to be used,
including and limited to:

- lfs.fetchexclude
- lfs.fetchinclude
- lfs.gitprotocol
- lfs.pushurl
- lfs.url
- lfs.extension.{name}.clean
- lfs.extension.{name}.smudge
- lfs.extension.{name}.priority
- remote.{name}.lfsurl
- remote.{name}.{*}.access

## EXAMPLES

*  Configure a custom LFS endpoint for your repository:

  `git config -f .lfsconfig lfs.url https://lfs.example.com/foo/bar/info/lfs`
