git-pull - Fetch from and integrate with another repository or a
local branch
git pull [options] [<repository> [<refspec>...]]
Incorporates changes from a remote repository into the current
branch. In its default mode, git pull is shorthand for git fetch
followed by git merge FETCH_HEAD.
More precisely, git pull runs git fetch with the given parameters and
calls git merge to merge the retrieved branch heads into the current
branch. With --rebase, it runs git rebase instead of git merge.
<repository> should be the name of a remote repository as passed to
git-fetch(1). <refspec> can name an arbitrary remote ref (for
example, the name of a tag) or even a collection of refs with
corresponding remote-tracking branches (e.g.,
refs/heads/*:refs/remotes/origin/*), but usually it is the name of a
branch in the remote repository.
Default values for <repository> and <branch> are read from the
"remote" and "merge" configuration for the current branch as set by
git-branch(1) --track.
Assume the following history exists and the current branch is
"master":
A---B---C master on origin
/
D---E---F---G master
^
origin/master in your repository
Then "git pull" will fetch and replay the changes from the remote
master branch since it diverged from the local master (i.e., E) until
its current commit (C) on top of master and record the result in a
new commit along with the names of the two parent commits and a log
message from the user describing the changes.
A---B---C origin/master
/ \
D---E---F---G---H master
See git-merge(1) for details, including how conflicts are presented
and handled.
In Git 1.7.0 or later, to cancel a conflicting merge, use git reset
--merge. Warning: In older versions of Git, running git pull with
uncommitted changes is discouraged: while possible, it leaves you in
a state that may be hard to back out of in the case of a conflict.
If any of the remote changes overlap with local uncommitted changes,
the merge will be automatically canceled and the work tree untouched.
It is generally best to get any local changes in working order before
pulling or stash them away with git-stash(1).
-q, --quiet
This is passed to both underlying git-fetch to squelch reporting
of during transfer, and underlying git-merge to squelch output
during merging.
-v, --verbose
Pass --verbose to git-fetch and git-merge.
--[no-]recurse-submodules[=yes|on-demand|no]
This option controls if new commits of all populated submodules
should be fetched and updated, too (see git-config(1) and
gitmodules(5)).
If the checkout is done via rebase, local submodule commits are
rebased as well.
If the update is done via merge, the submodule conflicts are
resolved and checked out.
Options related to merging
--commit, --no-commit
Perform the merge and commit the result. This option can be used
to override --no-commit.
With --no-commit perform the merge but pretend the merge failed
and do not autocommit, to give the user a chance to inspect and
further tweak the merge result before committing.
--edit, -e, --no-edit
Invoke an editor before committing successful mechanical merge to
further edit the auto-generated merge message, so that the user
can explain and justify the merge. The --no-edit option can be
used to accept the auto-generated message (this is generally
discouraged).
Older scripts may depend on the historical behaviour of not
allowing the user to edit the merge log message. They will see an
editor opened when they run git merge. To make it easier to
adjust such scripts to the updated behaviour, the environment
variable GIT_MERGE_AUTOEDIT can be set to no at the beginning of
them.
--ff
When the merge resolves as a fast-forward, only update the branch
pointer, without creating a merge commit. This is the default
behavior.
--no-ff
Create a merge commit even when the merge resolves as a
fast-forward. This is the default behaviour when merging an
annotated (and possibly signed) tag.
--ff-only
Refuse to merge and exit with a non-zero status unless the
current HEAD is already up to date or the merge can be resolved
as a fast-forward.
-S[<keyid>], --gpg-sign[=<keyid>]
GPG-sign the resulting merge commit. The keyid argument is
optional and defaults to the committer identity; if specified, it
must be stuck to the option without a space.
--log[=<n>], --no-log
In addition to branch names, populate the log message with
one-line descriptions from at most <n> actual commits that are
being merged. See also git-fmt-merge-msg(1).
With --no-log do not list one-line descriptions from the actual
commits being merged.
--signoff, --no-signoff
Add Signed-off-by line by the committer at the end of the commit
log message. The meaning of a signoff depends on the project, but
it typically certifies that committer has the rights to submit
this work under the same license and agrees to a Developer
Certificate of Origin (see http://developercertificate.org/ for
more information).
With --no-signoff do not add a Signed-off-by line.
--stat, -n, --no-stat
Show a diffstat at the end of the merge. The diffstat is also
controlled by the configuration option merge.stat.
With -n or --no-stat do not show a diffstat at the end of the
merge.
--squash, --no-squash
Produce the working tree and index state as if a real merge
happened (except for the merge information), but do not actually
make a commit, move the HEAD, or record $GIT_DIR/MERGE_HEAD (to
cause the next git commit command to create a merge commit). This
allows you to create a single commit on top of the current branch
whose effect is the same as merging another branch (or more in
case of an octopus).
With --no-squash perform the merge and commit the result. This
option can be used to override --squash.
-s <strategy>, --strategy=<strategy>
Use the given merge strategy; can be supplied more than once to
specify them in the order they should be tried. If there is no -s
option, a built-in list of strategies is used instead (git
merge-recursive when merging a single head, git merge-octopus
otherwise).
-X <option>, --strategy-option=<option>
Pass merge strategy specific option through to the merge
strategy.
--verify-signatures, --no-verify-signatures
Verify that the tip commit of the side branch being merged is
signed with a valid key, i.e. a key that has a valid uid: in the
default trust model, this means the signing key has been signed
by a trusted key. If the tip commit of the side branch is not
signed with a valid key, the merge is aborted.
--summary, --no-summary
Synonyms to --stat and --no-stat; these are deprecated and will
be removed in the future.
--allow-unrelated-histories
By default, git merge command refuses to merge histories that do
not share a common ancestor. This option can be used to override
this safety when merging histories of two projects that started
their lives independently. As that is a very rare occasion, no
configuration variable to enable this by default exists and will
not be added.
-r, --rebase[=false|true|preserve|interactive]
When true, rebase the current branch on top of the upstream
branch after fetching. If there is a remote-tracking branch
corresponding to the upstream branch and the upstream branch was
rebased since last fetched, the rebase uses that information to
avoid rebasing non-local changes.
When set to preserve, rebase with the --preserve-merges option
passed to git rebase so that locally created merge commits will
not be flattened.
When false, merge the current branch into the upstream branch.
When interactive, enable the interactive mode of rebase.
See pull.rebase, branch.<name>.rebase and branch.autoSetupRebase
in git-config(1) if you want to make git pull always use --rebase
instead of merging.
Note
This is a potentially dangerous mode of operation. It
rewrites history, which does not bode well when you published
that history already. Do not use this option unless you have
read git-rebase(1) carefully.
--no-rebase
Override earlier --rebase.
--autostash, --no-autostash
Before starting rebase, stash local modifications away (see
git-stash(1)) if needed, and apply the stash entry when done.
--no-autostash is useful to override the rebase.autoStash
configuration variable (see git-config(1)).
This option is only valid when "--rebase" is used.
Options related to fetching
--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
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.
-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.
--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 git-config(1).
-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.
--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.
-4, --ipv4
Use IPv4 addresses only, ignoring IPv6 addresses.
-6, --ipv6
Use IPv6 addresses only, ignoring IPv4 addresses.
<repository>
The "remote" repository that is the source of a fetch or pull
operation. This parameter can be either a URL (see the section
GIT URLS below) or the name of a remote (see the section REMOTES
below).
<refspec>
Specifies which refs to fetch and which local refs to update.
When no <refspec>s appear on the command line, the refs to fetch
are read from remote.<repository>.fetch variables instead (see
git-fetch(1)).
The format of a <refspec> parameter is an optional plus +,
followed by the source <src>, followed by a colon :, followed by
the destination ref <dst>. The colon can be omitted when <dst> is
empty. <src> is typically a ref, but it can also be a fully
spelled hex object name.
tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>; it
requests fetching everything up to the given tag.
The remote ref that matches <src> is fetched, and if <dst> is not
empty string, the local ref that matches it is fast-forwarded
using <src>. If the optional plus + is used, the local ref is
updated even if it does not result in a fast-forward update.
Note
When the remote branch you want to fetch is known to be
rewound and rebased regularly, it is expected that its new
tip will not be descendant of its previous tip (as stored in
your remote-tracking branch the last time you fetched). You
would want to use the + sign to indicate non-fast-forward
updates will be needed for such branches. There is no way to
determine or declare that a branch will be made available in
a repository with this behavior; the pulling user simply must
know this is the expected usage pattern for a branch.
Note
There is a difference between listing multiple <refspec>
directly on git pull command line and having multiple
remote.<repository>.fetch entries in your configuration for a
<repository> and running a git pull command without any
explicit <refspec> parameters. <refspec>s listed explicitly
on the command line are always merged into the current branch
after fetching. In other words, if you list more than one
remote ref, git pull will create an Octopus merge. On the
other hand, if you do not list any explicit <refspec>
parameter on the command line, git pull will fetch all the
<refspec>s it finds in the remote.<repository>.fetch
configuration and merge only the first <refspec> found into
the current branch. This is because making an Octopus from
remote refs is rarely done, while keeping track of multiple
remote heads in one-go by fetching more than one is often
useful.
In general, URLs contain information about the transport protocol,
the address of the remote server, and the path to the repository.
Depending on the transport protocol, some of this information may be
absent.
Git supports ssh, git, http, and https protocols (in addition, ftp,
and ftps can be used for fetching, but this is inefficient and
deprecated; do not use it).
The native transport (i.e. git:// URL) does no authentication and
should be used with caution on unsecured networks.
The following syntaxes may be used with them:
· ssh://[user@]host.xz[:port]/path/to/repo.git/
· git://host.xz[:port]/path/to/repo.git/
· http[s]://host.xz[:port]/path/to/repo.git/
· ftp[s]://host.xz[:port]/path/to/repo.git/
An alternative scp-like syntax may also be used with the ssh
protocol:
· [user@]host.xz:path/to/repo.git/
This syntax is only recognized if there are no slashes before the
first colon. This helps differentiate a local path that contains a
colon. For example the local path foo:bar could be specified as an
absolute path or ./foo:bar to avoid being misinterpreted as an ssh
url.
The ssh and git protocols additionally support ~username expansion:
· ssh://[user@]host.xz[:port]/~[user]/path/to/repo.git/
· git://host.xz[:port]/~[user]/path/to/repo.git/
· [user@]host.xz:/~[user]/path/to/repo.git/
For local repositories, also supported by Git natively, the following
syntaxes may be used:
· /path/to/repo.git/
· file:///path/to/repo.git/
These two syntaxes are mostly equivalent, except when cloning, when
the former implies --local option. See git-clone(1) for details.
When Git doesn’t know how to handle a certain transport protocol, it
attempts to use the remote-<transport> remote helper, if one exists.
To explicitly request a remote helper, the following syntax may be
used:
· <transport>::<address>
where <address> may be a path, a server and path, or an arbitrary
URL-like string recognized by the specific remote helper being
invoked. See gitremote-helpers(1) for details.
If there are a large number of similarly-named remote repositories
and you want to use a different format for them (such that the URLs
you use will be rewritten into URLs that work), you can create a
configuration section of the form:
[url "<actual url base>"]
insteadOf = <other url base>
For example, with this:
[url "git://git.host.xz/"]
insteadOf = host.xz:/path/to/
insteadOf = work:
a URL like "work:repo.git" or like "host.xz:/path/to/repo.git" will
be rewritten in any context that takes a URL to be
"git://git.host.xz/repo.git".
If you want to rewrite URLs for push only, you can create a
configuration section of the form:
[url "<actual url base>"]
pushInsteadOf = <other url base>
For example, with this:
[url "ssh://example.org/"]
pushInsteadOf = git://example.org/
a URL like "git://example.org/path/to/repo.git" will be rewritten to
"ssh://example.org/path/to/repo.git" for pushes, but pulls will still
use the original URL.
The name of one of the following can be used instead of a URL as
<repository> argument:
· a remote in the Git configuration file: $GIT_DIR/config,
· a file in the $GIT_DIR/remotes directory, or
· a file in the $GIT_DIR/branches directory.
All of these also allow you to omit the refspec from the command line
because they each contain a refspec which git will use by default.
Named remote in configuration file
You can choose to provide the name of a remote which you had
previously configured using git-remote(1), git-config(1) or even by a
manual edit to the $GIT_DIR/config file. The URL of this remote will
be used to access the repository. The refspec of this remote will be
used by default when you do not provide a refspec on the command
line. The entry in the config file would appear like this:
[remote "<name>"]
url = <url>
pushurl = <pushurl>
push = <refspec>
fetch = <refspec>
The <pushurl> is used for pushes only. It is optional and defaults to
<url>.
Named file in $GIT_DIR/remotes
You can choose to provide the name of a file in $GIT_DIR/remotes. The
URL in this file will be used to access the repository. The refspec
in this file will be used as default when you do not provide a
refspec on the command line. This file should have the following
format:
URL: one of the above URL format
Push: <refspec>
Pull: <refspec>
Push: lines are used by git push and Pull: lines are used by git pull
and git fetch. Multiple Push: and Pull: lines may be specified for
additional branch mappings.
Named file in $GIT_DIR/branches
You can choose to provide the name of a file in $GIT_DIR/branches.
The URL in this file will be used to access the repository. This file
should have the following format:
<url>#<head>
<url> is required; #<head> is optional.
Depending on the operation, git will use one of the following
refspecs, if you don’t provide one on the command line. <branch> is
the name of this file in $GIT_DIR/branches and <head> defaults to
master.
git fetch uses:
refs/heads/<head>:refs/heads/<branch>
git push uses:
HEAD:refs/heads/<head>
The merge mechanism (git merge and git pull commands) allows the
backend merge strategies to be chosen with -s option. Some strategies
can also take their own options, which can be passed by giving
-X<option> arguments to git merge and/or git pull.
resolve
This can only resolve two heads (i.e. the current branch and
another branch you pulled from) using a 3-way merge algorithm. It
tries to carefully detect criss-cross merge ambiguities and is
considered generally safe and fast.
recursive
This can only resolve two heads using a 3-way merge algorithm.
When there is more than one common ancestor that can be used for
3-way merge, it creates a merged tree of the common ancestors and
uses that as the reference tree for the 3-way merge. This has
been reported to result in fewer merge conflicts without causing
mismerges by tests done on actual merge commits taken from Linux
2.6 kernel development history. Additionally this can detect and
handle merges involving renames. This is the default merge
strategy when pulling or merging one branch.
The recursive strategy can take the following options:
ours
This option forces conflicting hunks to be auto-resolved
cleanly by favoring our version. Changes from the other tree
that do not conflict with our side are reflected to the merge
result. For a binary file, the entire contents are taken from
our side.
This should not be confused with the ours merge strategy,
which does not even look at what the other tree contains at
all. It discards everything the other tree did, declaring our
history contains all that happened in it.
theirs
This is the opposite of ours; note that, unlike ours, there
is no theirs merge stragegy to confuse this merge option
with.
patience
With this option, merge-recursive spends a little extra time
to avoid mismerges that sometimes occur due to unimportant
matching lines (e.g., braces from distinct functions). Use
this when the branches to be merged have diverged wildly. See
also git-diff(1) --patience.
diff-algorithm=[patience|minimal|histogram|myers]
Tells merge-recursive to use a different diff algorithm,
which can help avoid mismerges that occur due to unimportant
matching lines (such as braces from distinct functions). See
also git-diff(1) --diff-algorithm.
ignore-space-change, ignore-all-space, ignore-space-at-eol,
ignore-cr-at-eol
Treats lines with the indicated type of whitespace change as
unchanged for the sake of a three-way merge. Whitespace
changes mixed with other changes to a line are not ignored.
See also git-diff(1) -b, -w, --ignore-space-at-eol, and
--ignore-cr-at-eol.
· If their version only introduces whitespace changes to a
line, our version is used;
· If our version introduces whitespace changes but their
version includes a substantial change, their version is
used;
· Otherwise, the merge proceeds in the usual way.
renormalize
This runs a virtual check-out and check-in of all three
stages of a file when resolving a three-way merge. This
option is meant to be used when merging branches with
different clean filters or end-of-line normalization rules.
See "Merging branches with differing checkin/checkout
attributes" in gitattributes(5) for details.
no-renormalize
Disables the renormalize option. This overrides the
merge.renormalize configuration variable.
no-renames
Turn off rename detection. See also git-diff(1) --no-renames.
find-renames[=<n>]
Turn on rename detection, optionally setting the similarity
threshold. This is the default. See also git-diff(1)
--find-renames.
rename-threshold=<n>
Deprecated synonym for find-renames=<n>.
subtree[=<path>]
This option is a more advanced form of subtree strategy,
where the strategy makes a guess on how two trees must be
shifted to match with each other when merging. Instead, the
specified path is prefixed (or stripped from the beginning)
to make the shape of two trees to match.
octopus
This resolves cases with more than two heads, but refuses to do a
complex merge that needs manual resolution. It is primarily meant
to be used for bundling topic branch heads together. This is the
default merge strategy when pulling or merging more than one
branch.
ours
This resolves any number of heads, but the resulting tree of the
merge is always that of the current branch head, effectively
ignoring all changes from all other branches. It is meant to be
used to supersede old development history of side branches. Note
that this is different from the -Xours option to the recursive
merge strategy.
subtree
This is a modified recursive strategy. When merging trees A and
B, if B corresponds to a subtree of A, B is first adjusted to
match the tree structure of A, instead of reading the trees at
the same level. This adjustment is also done to the common
ancestor tree.
With the strategies that use 3-way merge (including the default,
recursive), if a change is made on both branches, but later reverted
on one of the branches, that change will be present in the merged
result; some people find this behavior confusing. It occurs because
only the heads and the merge base are considered when performing a
merge, not the individual commits. The merge algorithm therefore
considers the reverted change as no change at all, and substitutes
the changed version instead.
Often people use git pull without giving any parameter.
Traditionally, this has been equivalent to saying git pull origin.
However, when configuration branch.<name>.remote is present while on
branch <name>, that value is used instead of origin.
In order to determine what URL to use to fetch from, the value of the
configuration remote.<origin>.url is consulted and if there is not
any such variable, the value on the URL: line in
$GIT_DIR/remotes/<origin> is used.
In order to determine what remote branches to fetch (and optionally
store in the remote-tracking branches) when the command is run
without any refspec parameters on the command line, values of the
configuration variable remote.<origin>.fetch are consulted, and if
there aren’t any, $GIT_DIR/remotes/<origin> is consulted and its
Pull: lines are used. In addition to the refspec formats described in
the OPTIONS section, you can have a globbing refspec that looks like
this:
refs/heads/*:refs/remotes/origin/*
A globbing refspec must have a non-empty RHS (i.e. must store what
were fetched in remote-tracking branches), and its LHS and RHS must
end with /*. The above specifies that all remote branches are tracked
using remote-tracking branches in refs/remotes/origin/ hierarchy
under the same name.
The rule to determine which remote branch to merge after fetching is
a bit involved, in order not to break backward compatibility.
If explicit refspecs were given on the command line of git pull, they
are all merged.
When no refspec was given on the command line, then git pull uses the
refspec from the configuration or $GIT_DIR/remotes/<origin>. In such
cases, the following rules apply:
1. If branch.<name>.merge configuration for the current branch
<name> exists, that is the name of the branch at the remote site
that is merged.
2. If the refspec is a globbing one, nothing is merged.
3. Otherwise the remote branch of the first refspec is merged.
· Update the remote-tracking branches for the repository you cloned
from, then merge one of them into your current branch:
$ git pull
$ git pull origin
Normally the branch merged in is the HEAD of the remote
repository, but the choice is determined by the
branch.<name>.remote and branch.<name>.merge options; see
git-config(1) for details.
· Merge into the current branch the remote branch next:
$ git pull origin next
This leaves a copy of next temporarily in FETCH_HEAD, but does
not update any remote-tracking branches. Using remote-tracking
branches, the same can be done by invoking fetch and merge:
$ git fetch origin
$ git merge origin/next
If you tried a pull which resulted in complex conflicts and would
want to start over, you can recover with git reset.
The fetch and push protocols are not designed to prevent one side
from stealing data from the other repository that was not intended to
be shared. If you have private data that you need to protect from a
malicious peer, your best option is to store it in another
repository. This applies to both clients and servers. In particular,
namespaces on a server are not effective for read access control; you
should only grant read access to a namespace to clients that you
would trust with read access to the entire repository.
The known attack vectors are as follows:
1. The victim sends "have" lines advertising the IDs of objects it
has that are not explicitly intended to be shared but can be used
to optimize the transfer if the peer also has them. The attacker
chooses an object ID X to steal and sends a ref to X, but isn’t
required to send the content of X because the victim already has
it. Now the victim believes that the attacker has X, and it sends
the content of X back to the attacker later. (This attack is most
straightforward for a client to perform on a server, by creating
a ref to X in the namespace the client has access to and then
fetching it. The most likely way for a server to perform it on a
client is to "merge" X into a public branch and hope that the
user does additional work on this branch and pushes it back to
the server without noticing the merge.)
2. As in #1, the attacker chooses an object ID X to steal. The
victim sends an object Y that the attacker already has, and the
attacker falsely claims to have X and not Y, so the victim sends
Y as a delta against X. The delta reveals regions of X that are
similar to Y to the attacker.
Using --recurse-submodules can only fetch new commits in already
checked out submodules right now. When e.g. upstream added a new
submodule in the just fetched commits of the superproject the
submodule itself can not be fetched, making it impossible to check
out that submodule later without having to do a fetch again. This is
expected to be fixed in a future Git version.
