git-lfs-config - Configuration options for git-lfs


git-lfs reads its configuration from a file called .lfsconfig at the root of the reposi‐ tory. 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 or similar, although occasionally an lfs option can be scoped inside the configuration for a remote.


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 con‐ nection. 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 connec‐ tions. Default: 30 minutes. · 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. · 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 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 API. Once this feature is finalized, this setting will be removed, and 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 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. · 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: true. 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 consid‐ ered 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 (authen‐ tication 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:‐ fig-httplturlgt. To set this value per-host: git config --global lfs. [true|false]. · 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 suc‐ cess 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´.


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


Configure a custom LFS endpoint for your repository: git config -f .lfsconfig lfs.url
