[git-htmldocs.git] / fetch-options.txt

--[no-]all::
        Fetch all remotes. This overrides the configuration variable
        `fetch.all`.

-a::
--append::
        Append ref names and object names of fetched refs to the
        existing contents of `.git/FETCH_HEAD`.  Without this
        option old data in `.git/FETCH_HEAD` will be overwritten.

--atomic::
        Use an atomic transaction to update local refs. Either all refs are
        updated, or on error, no refs are updated.

--depth=<depth>::
        Limit fetching to the specified number of commits from the tip of
        each remote branch history. If fetching to a 'shallow' repository
        created by `git clone` with `--depth=<depth>` option (see
        linkgit:git-clone[1]), deepen or shorten the history to the specified
        number of commits. Tags for the deepened commits are not fetched.

--deepen=<depth>::
        Similar to --depth, except it specifies the number of commits
        from the current shallow boundary instead of from the tip of
        each remote branch history.

--shallow-since=<date>::
        Deepen or shorten the history of a shallow repository to
        include all reachable commits after <date>.

--shallow-exclude=<revision>::
        Deepen or shorten the history of a shallow repository to
        exclude commits reachable from a specified remote branch or tag.
        This option can be specified multiple times.

--unshallow::
        If the source repository is complete, convert a shallow
        repository to a complete one, removing all the limitations
        imposed by shallow repositories.
+
If the source repository is shallow, fetch as much as possible so that
the current repository has the same history as the source repository.

--update-shallow::
        By default when fetching from a shallow repository,
        `git fetch` refuses refs that require updating
        .git/shallow. This option updates .git/shallow and accepts such
        refs.

--negotiation-tip=<commit|glob>::
        By default, Git will report, to the server, commits reachable
        from all local refs to find common commits in an attempt to
        reduce the size of the to-be-received packfile. If specified,
        Git will only report commits reachable from the given tips.
        This is useful to speed up fetches when the user knows which
        local ref is likely to have commits in common with the
        upstream ref being fetched.
+
This option may be specified more than once; if so, Git will report
commits reachable from any of the given commits.
+
The argument to this option may be a glob on ref names, a ref, or the (possibly
abbreviated) SHA-1 of a commit. Specifying a glob is equivalent to specifying
this option multiple times, one for each matching ref name.
+
See also the `fetch.negotiationAlgorithm` and `push.negotiate`
configuration variables documented in linkgit:git-config[1], and the
`--negotiate-only` option below.

--negotiate-only::
        Do not fetch anything from the server, and instead print the
        ancestors of the provided `--negotiation-tip=*` arguments,
        which we have in common with the server.
+
This is incompatible with `--recurse-submodules=[yes|on-demand]`.
Internally this is used to implement the `push.negotiate` option, see
linkgit:git-config[1].

--dry-run::
        Show what would be done, without making any changes.

--porcelain::
        Print the output to standard output in an easy-to-parse format for
        scripts. See section OUTPUT in linkgit:git-fetch[1] for details.
+
This is incompatible with `--recurse-submodules=[yes|on-demand]` and takes
precedence over the `fetch.output` config option.

ifndef::git-pull[]
--[no-]write-fetch-head::
        Write the list of remote refs fetched in the `FETCH_HEAD`
        file directly under `$GIT_DIR`.  This is the default.
        Passing `--no-write-fetch-head` from the command line tells
        Git not to write the file.  Under `--dry-run` option, the
        file is never written.
endif::git-pull[]

-f::
--force::
        When 'git fetch' is used with `<src>:<dst>` refspec, it may
        refuse to update the local branch as discussed
ifdef::git-pull[]
        in the `<refspec>` part of the linkgit:git-fetch[1]
        documentation.
endif::git-pull[]
ifndef::git-pull[]
        in the `<refspec>` part below.
endif::git-pull[]
        This option overrides that check.

-k::
--keep::
        Keep downloaded pack.

ifndef::git-pull[]
--multiple::
        Allow several <repository> and <group> arguments to be
        specified. No <refspec>s may be specified.

--[no-]auto-maintenance::
--[no-]auto-gc::
        Run `git maintenance run --auto` at the end to perform automatic
        repository maintenance if needed. (`--[no-]auto-gc` is a synonym.)
        This is enabled by default.

--[no-]write-commit-graph::
        Write a commit-graph after fetching. This overrides the config
        setting `fetch.writeCommitGraph`.
endif::git-pull[]

--prefetch::
        Modify the configured refspec to place all refs into the
        `refs/prefetch/` namespace. See the `prefetch` task in
        linkgit:git-maintenance[1].

-p::
--prune::
        Before fetching, remove any remote-tracking references that no
        longer exist on the remote.  Tags are not subject to pruning
        if they are fetched only because of the default tag
        auto-following or due to a --tags option.  However, if tags
        are fetched due to an explicit refspec (either on the command
        line or in the remote configuration, for example if the remote
        was cloned with the --mirror option), then they are also
        subject to pruning. Supplying `--prune-tags` is a shorthand for
        providing the tag refspec.
ifndef::git-pull[]
+
See the PRUNING section below for more details.

-P::
--prune-tags::
        Before fetching, remove any local tags that no longer exist on
        the remote if `--prune` is enabled. This option should be used
        more carefully, unlike `--prune` it will remove any local
        references (local tags) that have been created. This option is
        a shorthand for providing the explicit tag refspec along with
        `--prune`, see the discussion about that in its documentation.
+
See the PRUNING section below for more details.

endif::git-pull[]

ifndef::git-pull[]
-n::
endif::git-pull[]
--no-tags::
        By default, tags that point at objects that are downloaded
        from the remote repository are fetched and stored locally.
        This option disables this automatic tag following. The default
        behavior for a remote may be specified with the remote.<name>.tagOpt
        setting. See linkgit:git-config[1].

ifndef::git-pull[]
--refetch::
        Instead of negotiating with the server to avoid transferring commits and
        associated objects that are already present locally, this option fetches
        all objects as a fresh clone would. Use this to reapply a partial clone
        filter from configuration or using `--filter=` when the filter
        definition has changed. Automatic post-fetch maintenance will perform
        object database pack consolidation to remove any duplicate objects.
endif::git-pull[]

--refmap=<refspec>::
        When fetching refs listed on the command line, use the
        specified refspec (can be given more than once) to map the
        refs to remote-tracking branches, instead of the values of
        `remote.*.fetch` configuration variables for the remote
        repository.  Providing an empty `<refspec>` to the
        `--refmap` option causes Git to ignore the configured
        refspecs and rely entirely on the refspecs supplied as
        command-line arguments. See section on "Configured Remote-tracking
        Branches" for details.

-t::
--tags::
        Fetch all tags from the remote (i.e., fetch remote tags
        `refs/tags/*` into local tags with the same name), in addition
        to whatever else would otherwise be fetched.  Using this
        option alone does not subject tags to pruning, even if --prune
        is used (though tags may be pruned anyway if they are also the
        destination of an explicit refspec; see `--prune`).

ifndef::git-pull[]
--recurse-submodules[=(yes|on-demand|no)]::
        This option controls if and under what conditions new commits of
        submodules should be fetched too. When recursing through submodules,
        `git fetch` always attempts to fetch "changed" submodules, that is, a
        submodule that has commits that are referenced by a newly fetched
        superproject commit but are missing in the local submodule clone. A
        changed submodule can be fetched as long as it is present locally e.g.
        in `$GIT_DIR/modules/` (see linkgit:gitsubmodules[7]); if the upstream
        adds a new submodule, that submodule cannot be fetched until it is
        cloned e.g. by `git submodule update`.
+
When set to 'on-demand', only changed submodules are fetched. When set
to 'yes', all populated submodules are fetched and submodules that are
both unpopulated and changed are fetched. When set to 'no', submodules
are never fetched.
+
When unspecified, this uses the value of `fetch.recurseSubmodules` if it
is set (see linkgit:git-config[1]), defaulting to 'on-demand' if unset.
When this option is used without any value, it defaults to 'yes'.
endif::git-pull[]

-j::
--jobs=<n>::
        Number of parallel children to be used for all forms of fetching.
+
If the `--multiple` option was specified, the different remotes will be fetched
in parallel. If multiple submodules are fetched, they will be fetched in
parallel. To control them independently, use the config settings
`fetch.parallel` and `submodule.fetchJobs` (see linkgit:git-config[1]).
+
Typically, parallel recursive and multi-remote fetches will be faster. By
default fetches are performed sequentially, not in parallel.

ifndef::git-pull[]
--no-recurse-submodules::
        Disable recursive fetching of submodules (this has the same effect as
        using the `--recurse-submodules=no` option).
endif::git-pull[]

--set-upstream::
        If the remote is fetched successfully, add upstream
        (tracking) reference, used by argument-less
        linkgit:git-pull[1] and other commands. For more information,
        see `branch.<name>.merge` and `branch.<name>.remote` in
        linkgit:git-config[1].

ifndef::git-pull[]
--submodule-prefix=<path>::
        Prepend <path> to paths printed in informative messages
        such as "Fetching submodule foo".  This option is used
        internally when recursing over submodules.

--recurse-submodules-default=[yes|on-demand]::
        This option is used internally to temporarily provide a
        non-negative default value for the --recurse-submodules
        option.  All other methods of configuring fetch's submodule
        recursion (such as settings in linkgit:gitmodules[5] and
        linkgit:git-config[1]) override this option, as does
        specifying --[no-]recurse-submodules directly.

-u::
--update-head-ok::
        By default 'git fetch' refuses to update the head which
        corresponds to the current branch.  This flag disables the
        check.  This is purely for the internal use for 'git pull'
        to communicate with 'git fetch', and unless you are
        implementing your own Porcelain you are not supposed to
        use it.
endif::git-pull[]

--upload-pack <upload-pack>::
        When given, and the repository to fetch from is handled
        by 'git fetch-pack', `--exec=<upload-pack>` is passed to
        the command to specify non-default path for the command
        run on the other end.

ifndef::git-pull[]
-q::
--quiet::
        Pass --quiet to git-fetch-pack and silence any other internally
        used git commands. Progress is not reported to the standard error
        stream.

-v::
--verbose::
        Be verbose.
endif::git-pull[]

--progress::
        Progress status is reported on the standard error stream
        by default when it is attached to a terminal, unless -q
        is specified. This flag forces progress status even if the
        standard error stream is not directed to a terminal.

-o <option>::
--server-option=<option>::
        Transmit the given string to the server when communicating using
        protocol version 2.  The given string must not contain a NUL or LF
        character.  The server's handling of server options, including
        unknown ones, is server-specific.
        When multiple `--server-option=<option>` are given, they are all
        sent to the other side in the order listed on the command line.

--show-forced-updates::
        By default, git checks if a branch is force-updated during
        fetch. This can be disabled through fetch.showForcedUpdates, but
        the --show-forced-updates option guarantees this check occurs.
        See linkgit:git-config[1].

--no-show-forced-updates::
        By default, git checks if a branch is force-updated during
        fetch. Pass --no-show-forced-updates or set fetch.showForcedUpdates
        to false to skip this check for performance reasons. If used during
        'git-pull' the --ff-only option will still check for forced updates
        before attempting a fast-forward update. See linkgit:git-config[1].

-4::
--ipv4::
        Use IPv4 addresses only, ignoring IPv6 addresses.

-6::
--ipv6::
        Use IPv6 addresses only, ignoring IPv4 addresses.
