Fetching from a shallow-cloned repository used to be forbidden, primarily because the codepaths involved were not carefully vetted and we did not bother supporting such usage. This attempts to allow object transfer out of a shallow-cloned repository in a controlled way (i.e. the receiver become a shallow repository with truncated history). * nd/shallow-clone: (31 commits) t5537: fix incorrect expectation in test case 10 shallow: remove unused code send-pack.c: mark a file-local function static git-clone.txt: remove shallow clone limitations prune: clean .git/shallow after pruning objects clone: use git protocol for cloning shallow repo locally send-pack: support pushing from a shallow clone via http receive-pack: support pushing to a shallow clone via http smart-http: support shallow fetch/clone remote-curl: pass ref SHA-1 to fetch-pack as well send-pack: support pushing to a shallow clone receive-pack: allow pushes that update .git/shallow connected.c: add new variant that runs with --shallow-file add GIT_SHALLOW_FILE to propagate --shallow-file to subprocesses receive/send-pack: support pushing from a shallow clone receive-pack: reorder some code in unpack() fetch: add --update-shallow to accept refs that update .git/shallow upload-pack: make sure deepening preserves shallow roots fetch: support fetching from a shallow repository clone: support remote shallow repository ...

--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::
|
|
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 accept such
|
|
refs.
|
|
|
|
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::
|
|
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.
|
|
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[]
|
|
-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').
|
|
|
|
--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.
|
|
|
|
--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.
