The rules used by "git push" and "git fetch" to determine if a ref can or cannot be updated were inconsistent; specifically, fetching to update existing tags were allowed even though tags are supposed to be unmoving anchoring points. "git fetch" was taught to forbid updates to existing tags without the "--force" option. * ab/fetch-tags-noclobber: fetch: stop clobbering existing tags without --force fetch: document local ref updates with/without --force push doc: correct lies about how push refspecs work push doc: move mention of "tag <tag>" later in the prose push doc: remove confusing mention of remote merger fetch tests: add a test for clobbering tag behavior push tests: use spaces in interpolated string push tests: make use of unused $1 in test description fetch: change "branch" to "reference" in --force -h output

--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>::
|
|
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 accept 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` configuration variable
|
|
documented in linkgit:git-config[1].
|
|
|
|
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 `<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.
|
|
|
|
-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.
|
|
+
|
|
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[]
|
|
--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. 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`).
|
|
|
|
--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.
|
|
|
|
-j::
|
|
--jobs=<n>::
|
|
Number of parallel children to be used for fetching submodules.
|
|
Each will fetch from different submodules, such that fetching many
|
|
submodules will be faster. By default submodules will be fetched
|
|
one at a time.
|
|
|
|
--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.
|
|
|
|
-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.
|
|
When multiple `--server-option=<option>` are given, they are all
|
|
sent to the other side in the order listed on the command line.
|
|
|
|
-4::
|
|
--ipv4::
|
|
Use IPv4 addresses only, ignoring IPv6 addresses.
|
|
|
|
-6::
|
|
--ipv6::
|
|
Use IPv6 addresses only, ignoring IPv4 addresses.
