Raw Normal View History

--all::
Fetch all remotes.
-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.
--depth=<depth>::
Deepen or shorten the history of a 'shallow' repository created by
`git clone` with `--depth=<depth>` option (see linkgit:git-clone[1])
to the specified number of commits from the tip of each remote
branch history. Tags for the deepened commits are not fetched.
--unshallow::
Convert a shallow repository to a complete one, removing all
the limitations imposed by shallow repositories.
ifndef::git-pull[]
--dry-run::
Show what would be done, without making any changes.
endif::git-pull[]
-f::
--force::
When 'git fetch' is used with `<rbranch>:<lbranch>`
refspec, it refuses to update the local branch
`<lbranch>` unless the remote branch `<rbranch>` it
fetches is a descendant of `<lbranch>`. 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.
-p::
--prune::
fetch --prune: prune only based on explicit refspecs The old behavior of "fetch --prune" was to prune whatever was being fetched. In particular, "fetch --prune --tags" caused tags not only to be fetched, but also to be pruned. This is inappropriate because there is only one tags namespace that is shared among the local repository and all remotes. Therefore, if the user defines a local tag and then runs "git fetch --prune --tags", then the local tag is deleted. Moreover, "--prune" and "--tags" can also be configured via fetch.prune / remote.<name>.prune and remote.<name>.tagopt, making it even less obvious that an invocation of "git fetch" could result in tag lossage. Since the command "git remote update" invokes "git fetch", it had the same problem. The command "git remote prune", on the other hand, disregarded the setting of remote.<name>.tagopt, and so its behavior was inconsistent with that of the other commands. So the old behavior made it too easy to lose tags. To fix this problem, change "fetch --prune" to prune references based only on refspecs specified explicitly by the user, either on the command line or via remote.<name>.fetch. Thus, tags are no longer made subject to pruning by the --tags option or the remote.<name>.tagopt setting. However, tags *are* still subject to pruning if they are fetched as part of a refspec, and that is good. For example: * On the command line, git fetch --prune 'refs/tags/*:refs/tags/*' causes tags, and only tags, to be fetched and pruned, and is therefore a simple way for the user to get the equivalent of the old behavior of "--prune --tag". * For a remote that was configured with the "--mirror" option, the configuration is set to include [remote "name"] fetch = +refs/*:refs/* , which causes tags to be subject to pruning along with all other references. This is the behavior that will typically be desired for a mirror. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>

After 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.

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].

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').
--recurse-submodules[=yes|on-demand|no]::
This option controls if and under what conditions new commits of
populated submodules should be fetched too. It can be used as a
boolean option to completely disable recursion when set to 'no' or to
unconditionally recurse into all populated submodules when set to
'yes', which is the default when this option is used without any
value. Use 'on-demand' to only recurse into a populated submodule
when the superproject retrieves a commit that updates the submodule's
reference to a commit that isn't already in the local submodule
clone.
--no-recurse-submodules::
Disable recursive fetching of submodules (this has the same effect as
using the '--recurse-submodules=no' option).
--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.
fetch/pull: recurse into submodules when necessary To be able to access all commits of populated submodules referenced by the superproject it is sufficient to only then let "git fetch" recurse into a submodule when the new commits fetched in the superproject record new commits for it. Having these commits present is extremely useful when using the "--submodule" option to "git diff" (which is what "git gui" and "gitk" do since 1.6.6), as all submodule commits needed for creating a descriptive output can be accessed. Also merging submodule commits (added in 1.7.3) depends on the submodule commits in question being present to work. Last but not least this enables disconnected operation when using submodules, as all commits necessary for a successful "git submodule update -N" will have been fetched automatically. So we choose this mode as the default for fetch and pull. Before a new or changed ref from upstream is updated in update_local_ref() "git rev-list <new-sha1> --not --branches --remotes" is used to determine all newly fetched commits. These are then walked and diffed against their parent(s) to see if a submodule has been changed. If that is the case, its path is stored to be fetched after the superproject fetch is completed. Using the "--recurse-submodules" or the "--no-recurse-submodules" option disables the examination of the fetched refs because the result will be ignored anyway. There is currently no infrastructure for storing deleted and new submodules in the .git directory of the superproject. That's why fetch and pull for now only fetch submodules that are already checked out and are not renamed. In t7403 the "--no-recurse-submodules" argument had to be added to "git pull" to avoid failure because of the moved upstream submodule repo.

--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.
endif::git-pull[]
-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.
--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.
