44 Updates remote refs using local refs, while sending objects necessary to complete the given refs\&.
46 You can make interesting things happen to a repository every time you push into it, by setting up \fIhooks\fR there\&. See documentation for \fBgit-receive-pack\fR(1)\&.
48 When the command line does not specify where to push with the \fI<repository>\fR argument, \fBbranch\&.\fR*\&.\fBremote\fR configuration for the current branch is consulted to determine where to push\&. If the configuration is missing, it defaults to \fIorigin\fR\&.
50 When the command line does not specify what to push with \fI<refspec>\fR\&.\&.\&. arguments or \fB\-\-all\fR, \fB\-\-mirror\fR, \fB\-\-tags\fR options, the command finds the default \fI<refspec>\fR by consulting \fBremote\&.\fR*\&.\fBpush\fR configuration, and if it is not found, honors \fBpush\&.default\fR configuration to decide what to push (See \fBgit-config\fR(1) for the meaning of \fBpush\&.default\fR)\&.
52 When neither the command\-line nor the configuration specifies what to push, the default behavior is used, which corresponds to the \fBsimple\fR value for \fBpush\&.default\fR: the current branch is pushed to the corresponding upstream branch, but as a safety measure, the push is aborted if the upstream branch does not have the same name as the local one\&.
57 The "remote" repository that is the destination of a push operation\&. This parameter can be either a URL (see the section
59 below) or the name of a remote (see the section
66 Specify what destination ref to update with what source object\&. The format of a <refspec> parameter is an optional plus
67 \fB+\fR, followed by the source object <src>, followed by a colon
68 \fB:\fR, followed by the destination ref <dst>\&.
70 The <src> is often the name of the branch you would want to push, but it can be any arbitrary "SHA\-1 expression", such as
75 \fBgitrevisions\fR(7))\&.
77 The <dst> tells which ref on the remote side is updated with this push\&. Arbitrary expressions cannot be used here, an actual ref must be named\&. If
80 [\fI<repository>\fR] without any
82 argument is set to update some ref at the destination with
85 \fBremote\&.\fR\fI<repository>\fR\fB\&.push\fR
86 configuration variable,
88 part can be omitted\(em\:such a push will update a ref that
90 normally updates without any
92 on the command line\&. Otherwise, missing
94 means to update the same ref as the
97 If <dst> doesn\(cqt start with
100 \fBrefs/heads/master\fR) we will try to infer where in
101 \fBrefs/\fR* on the destination <repository> it belongs based on the type of <src> being pushed and whether <dst> is ambiguous\&.
111 If <dst> unambiguously refers to a ref on the <repository> remote, then push to that ref\&.
122 If <src> resolves to a ref starting with refs/heads/ or refs/tags/, then prepend that to <dst>\&.
133 Other ambiguity resolutions might be added in the future, but for now any other cases will error out with an error indicating what we tried, and depending on the
134 \fBadvice\&.pushUnqualifiedRefname\fR
136 \fBgit-config\fR(1)) suggest what refs/ namespace you may have wanted to push to\&.
139 The object referenced by <src> is used to update the <dst> reference on the remote side\&. Whether this is allowed depends on where in
140 \fBrefs/\fR* the <dst> reference lives as described in detail below, in those sections "update" means any modifications except deletes, which as noted after the next few sections are treated differently\&.
143 \fBrefs/heads/\fR* namespace will only accept commit objects, and updates only if they can be fast\-forwarded\&.
146 \fBrefs/tags/\fR* namespace will accept any kind of object (as commits, trees and blobs can be tagged), and any updates to them will be rejected\&.
148 It\(cqs possible to push any type of object to any namespace outside of
149 \fBrefs/\fR{tags,heads}/*\&. In the case of tags and commits, these will be treated as if they were the commits inside
150 \fBrefs/heads/\fR* for the purposes of whether the update is allowed\&.
152 I\&.e\&. a fast\-forward of commits and tags outside
153 \fBrefs/\fR{tags,heads}/* is allowed, even in cases where what\(cqs being fast\-forwarded is not a commit, but a tag object which happens to point to a new commit which is a fast\-forward of the commit the last tag (or commit) it\(cqs replacing\&. Replacing a tag with an entirely different tag is also allowed, if it points to the same commit, as well as pushing a peeled tag, i\&.e\&. pushing the commit that existing tag object points to, or a new tag object which an existing commit points to\&.
155 Tree and blob objects outside of
156 \fBrefs/\fR{tags,heads}/* will be treated the same way as if they were inside
157 \fBrefs/tags/\fR*, any update of them will be rejected\&.
159 All of the rules described above about what\(cqs not allowed as an update can be overridden by adding an the optional leading
161 to a refspec (or using
163 command line option)\&. The only exception to this is that no amount of forcing will make the
164 \fBrefs/heads/\fR* namespace accept a non\-commit object\&. Hooks and configuration can also override or amend these rules, see e\&.g\&.
165 \fBreceive\&.denyNonFastForwards\fR
175 Pushing an empty <src> allows you to delete the <dst> ref from the remote repository\&. Deletions are always accepted without a leading
178 \fB\-\-force\fR), except when forbidden by configuration or hooks\&. See
179 \fBreceive\&.denyDeletes\fR
193 to allow non\-fast\-forward updates) directs Git to push "matching" branches: for every branch that exists on the local side, the remote side is updated if a branch of the same name already exists on the remote side\&.
198 \fBrefs/tags/\fR\fI<tag>\fR\fB:refs/tags/\fR\fI<tag>\fR\&.
201 \-\-all, \-\-branches
203 Push all branches (i\&.e\&. refs under
204 \fBrefs/heads/\fR); cannot be used with other <refspec>\&.
209 Remove remote branches that don\(cqt have a local counterpart\&. For example a remote branch
211 will be removed if a local branch with the same name doesn\(cqt exist any more\&. This also respects refspecs, e\&.g\&.
216 \fBrefs/heads/\fR*:refs/tmp/* would make sure that remote
225 Instead of naming each ref to push, specifies that all refs under
227 (which includes but is not limited to
229 \fBrefs/remotes/\fR, and
230 \fBrefs/tags/\fR) be mirrored to the remote repository\&. Newly created local refs will be pushed to the remote end, locally updated refs will be force updated on the remote end, and deleted refs will be removed from the remote end\&. This is the default if the configuration option
231 \fBremote\&.\fR\fI<remote>\fR\fB\&.mirror\fR
237 Do everything except actually send the updates\&.
242 Produce machine\-readable output\&. The output status line for each ref will be tab\-separated and sent to stdout instead of stderr\&. The full symbolic names of the refs will be given\&.
247 All listed refs are deleted from the remote repository\&. This is the same as prefixing all refs with a colon\&.
254 are pushed, in addition to refspecs explicitly listed on the command line\&.
259 Push all the refs that would be pushed without this option, and also push annotated tags in
261 that are missing from the remote but are pointing at commit\-ish that are reachable from the refs being pushed\&. This can also be specified with configuration variable
262 \fBpush\&.followTags\fR\&. For more information, see
263 \fBpush\&.followTags\fR
265 \fBgit-config\fR(1)\&.
268 \-\-[no\-]signed, \-\-signed=(true|false|if\-asked)
270 GPG\-sign the push request to update refs on the receiving side, to allow it to be checked by the hooks and/or be logged\&. If
273 \fB\-\-no\-signed\fR, no signing will be attempted\&. If
276 \fB\-\-signed\fR, the push will fail if the server does not support signed pushes\&. If set to
277 \fBif\-asked\fR, sign if and only if the server supports signed pushes\&. The push will also fail if the actual call to
281 \fBgit-receive-pack\fR(1)
282 for the details on the receiving end\&.
287 Use an atomic transaction on the remote side if available\&. Either all refs are updated, or on error, no refs are updated\&. If the server does not support atomic pushes the push will fail\&.
290 \-o <option>, \-\-push\-option=<option>
292 Transmit the given string to the server, which passes them to the pre\-receive as well as the post\-receive hook\&. The given string must not contain a NUL or LF character\&. When multiple
293 \fB\-\-push\-option=\fR\fI<option>\fR
294 are given, they are all sent to the other side in the order listed on the command line\&. When no
295 \fB\-\-push\-option=\fR\fI<option>\fR
296 is given from the command line, the values of configuration variable
297 \fBpush\&.pushOption\fR
301 \-\-receive\-pack=<git\-receive\-pack>, \-\-exec=<git\-receive\-pack>
304 \fIgit\-receive\-pack\fR
305 program on the remote end\&. Sometimes useful when pushing to a remote repository over ssh, and you do not have the program in a directory on the default $PATH\&.
308 \-\-[no\-]force\-with\-lease, \-\-force\-with\-lease=<refname>, \-\-force\-with\-lease=<refname>:<expect>
310 Usually, "git push" refuses to update a remote ref that is not an ancestor of the local ref used to overwrite it\&.
312 This option overrides this restriction if the current value of the remote ref is the expected value\&. "git push" fails otherwise\&.
314 Imagine that you have to rebase what you have already published\&. You will have to bypass the "must fast\-forward" rule in order to replace the history you originally published with the rebased history\&. If somebody else built on top of your original history while you are rebasing, the tip of the branch at the remote may advance with their commit, and blindly pushing with
316 will lose their work\&.
318 This option allows you to say that you expect the history you are updating is what you rebased and want to replace\&. If the remote ref still points at the commit you specified, you can be sure that no other people did anything to the ref\&. It is like taking a "lease" on the ref without explicitly locking it, and the remote ref is updated only if the "lease" is still valid\&.
320 \fB\-\-force\-with\-lease\fR
321 alone, without specifying the details, will protect all remote refs that are going to be updated by requiring their current value to be the same as the remote\-tracking branch we have for them\&.
323 \fB\-\-force\-with\-lease=\fR\fI<refname>\fR, without specifying the expected value, will protect the named ref (alone), if it is going to be updated, by requiring its current value to be the same as the remote\-tracking branch we have for it\&.
325 \fB\-\-force\-with\-lease=\fR\fI<refname>\fR\fB:\fR\fI<expect>\fR
326 will protect the named ref (alone), if it is going to be updated, by requiring its current value to be the same as the specified value
328 (which is allowed to be different from the remote\-tracking branch we have for the refname, or we do not even have to have such a remote\-tracking branch when this form is used)\&. If
330 is the empty string, then the named ref must not already exist\&.
332 Note that all forms other than
333 \fB\-\-force\-with\-lease=\fR\fI<refname>\fR\fB:\fR\fI<expect>\fR
334 that specifies the expected current value of the ref explicitly are still experimental and their semantics may change as we gain experience with this feature\&.
336 "\-\-no\-force\-with\-lease" will cancel all the previous \-\-force\-with\-lease on the command line\&.
338 A general note on safety: supplying this option without an expected value, i\&.e\&. as
339 \fB\-\-force\-with\-lease\fR
341 \fB\-\-force\-with\-lease=\fR\fI<refname>\fR
342 interacts very badly with anything that implicitly runs
345 on the remote to be pushed to in the background, e\&.g\&.
349 on your repository in a cronjob\&.
351 The protection it offers over
353 is ensuring that subsequent changes your work wasn\(cqt based on aren\(cqt clobbered, but this is trivially defeated if some background process is updating refs in the background\&. We don\(cqt have anything except the remote tracking info to go by as a heuristic for refs you\(cqre expected to have seen & are willing to clobber\&.
355 If your editor or some other system is running
358 in the background for you a way to mitigate this is to simply set up another remote:
364 git remote add origin\-push $(git config remote\&.origin\&.url)
365 git fetch origin\-push
371 Now when the background process runs
377 won\(cqt be updated, and thus commands like:
383 git push \-\-force\-with\-lease origin\-push
389 Will fail unless you manually run
392 \fBorigin\-push\fR\&. This method is of course entirely defeated by something that runs
395 \fB\-\-all\fR, in that case you\(cqd need to either disable it or do something more tedious like:
401 git fetch # update \*(Aqmaster\*(Aq from remote
402 git tag base master # mark our base point
403 git rebase \-i master # rewrite some commits
404 git push \-\-force\-with\-lease=master:base master:master
412 tag for versions of the upstream code that you\(cqve seen and are willing to overwrite, then rewrite history, and finally force push changes to
414 if the remote version is still at
415 \fBbase\fR, regardless of what your local
416 \fBremotes/origin/master\fR
417 has been updated to in the background\&.
419 Alternatively, specifying
420 \fB\-\-force\-if\-includes\fR
421 as an ancillary option along with
422 \fB\-\-force\-with\-lease\fR[\fB=\fR\fI<refname>\fR] (i\&.e\&., without saying what exact commit the ref on the remote side must be pointing at, or which refs on the remote side are being protected) at the time of "push" will verify if updates from the remote\-tracking refs that may have been implicitly updated in the background are integrated locally before allowing a forced update\&.
427 Usually, the command refuses to update a remote ref that is not an ancestor of the local ref used to overwrite it\&. Also, when
428 \fB\-\-force\-with\-lease\fR
429 option is used, the command refuses to update a remote ref whose current value does not match what is expected\&.
431 This flag disables these checks, and can cause the remote repository to lose commits; use it with care\&.
435 applies to all the refs that are pushed, hence using it with
439 or with multiple push destinations configured with
440 \fBremote\&.\fR*\&.\fBpush\fR
441 may overwrite refs other than the current branch (including local refs that are strictly behind their remote counterpart)\&. To force a push to only one branch, use a
443 in front of the refspec to push (e\&.g
448 to force a push to the
451 \fI<refspec>\fR\&.\&.\&. section above for details\&.
454 \-\-[no\-]force\-if\-includes
456 Force an update only if the tip of the remote\-tracking ref has been integrated locally\&.
458 This option enables a check that verifies if the tip of the remote\-tracking ref is reachable from one of the "reflog" entries of the local branch based in it for a rewrite\&. The check ensures that any updates from the remote have been incorporated locally by rejecting the forced update if that is not the case\&.
460 If the option is passed without specifying
461 \fB\-\-force\-with\-lease\fR, or specified along with
462 \fB\-\-force\-with\-lease=\fR\fI<refname>\fR\fB:\fR\fI<expect>\fR, it is a "no\-op"\&.
465 \fB\-\-no\-force\-if\-includes\fR
466 disables this behavior\&.
469 \-\-repo=<repository>
471 This option is equivalent to the <repository> argument\&. If both are specified, the command\-line argument takes precedence\&.
474 \-u, \-\-set\-upstream
476 For every branch that is up to date or successfully pushed, add upstream (tracking) reference, used by argument\-less
478 and other commands\&. For more information, see
479 \fBbranch\&.\fR\fI<name>\fR\fB\&.merge\fR
481 \fBgit-config\fR(1)\&.
486 These options are passed to
487 \fBgit-send-pack\fR(1)\&. A thin transfer significantly reduces the amount of sent data when the sender and receiver share many of the same objects in common\&. The default is
493 Suppress all output, including the listing of updated refs, unless an error occurs\&. Progress is not reported to the standard error stream\&.
503 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\&.
506 \-\-no\-recurse\-submodules, \-\-recurse\-submodules=check|on\-demand|only|no
508 May be used to make sure all submodule commits used by the revisions to be pushed are available on a remote\-tracking branch\&. If
510 is used Git will verify that all submodule commits that changed in the revisions to be pushed are available on at least one remote of the submodule\&. If any commits are missing the push will be aborted and exit with non\-zero status\&. If
512 is used all submodules that changed in the revisions to be pushed will be pushed\&. If on\-demand was not able to push all necessary revisions it will also be aborted and exit with non\-zero status\&. If
514 is used all submodules will be pushed while the superproject is left unpushed\&. A value of
517 \fB\-\-no\-recurse\-submodules\fR
518 can be used to override the push\&.recurseSubmodules configuration variable when no submodule recursion is required\&.
523 \fIonly\fR, if a submodule has a "push\&.recurseSubmodules={on\-demand,only}" or "submodule\&.recurse" configuration, further recursion will occur\&. In this case, "only" is treated as "on\-demand"\&.
528 Toggle the pre\-push hook (see
529 \fBgithooks\fR(5))\&. The default is \-\-verify, giving the hook a chance to prevent the push\&. With \-\-no\-verify, the hook is bypassed completely\&.
534 Use IPv4 addresses only, ignoring IPv6 addresses\&.
539 Use IPv6 addresses only, ignoring IPv4 addresses\&.
543 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\&.
545 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 them)\&.
547 The native transport (i\&.e\&. \fBgit://\fR URL) does no authentication and should be used with caution on unsecured networks\&.
549 The following syntaxes may be used with them:
559 \fBssh://\fR[\fI<user>\fR\fB@\fR]\fI<host>\fR[\fB:\fR\fI<port>\fR]\fB/\fR\fI<path\-to\-git\-repo>\fR
570 \fBgit://\fR\fI<host>\fR[\fB:\fR\fI<port>\fR]\fB/\fR\fI<path\-to\-git\-repo>\fR
581 \fBhttp\fR[\fBs\fR]\fB://\fR\fI<host>\fR[\fB:\fR\fI<port>\fR]\fB/\fR\fI<path\-to\-git\-repo>\fR
592 \fBftp\fR[\fBs\fR]\fB://\fR\fI<host>\fR[\fB:\fR\fI<port>\fR]\fB/\fR\fI<path\-to\-git\-repo>\fR
595 An alternative scp\-like syntax may also be used with the ssh protocol:
605 [\fI<user>\fR\fB@\fR]\fI<host>\fR\fB:/\fR\fI<path\-to\-git\-repo>\fR
608 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 \fBfoo:bar\fR could be specified as an absolute path or \&.\fB/foo:bar\fR to avoid being misinterpreted as an ssh url\&.
610 The ssh and git protocols additionally support \fB~\fR\fI<username>\fR expansion:
620 \fBssh://\fR[\fI<user>\fR\fB@\fR]\fI<host>\fR[\fB:\fR\fI<port>\fR]\fB/~\fR\fI<user>\fR\fB/\fR\fI<path\-to\-git\-repo>\fR
631 \fBgit://\fR\fI<host>\fR[\fB:\fR\fI<port>\fR]\fB/~\fR\fI<user>\fR\fB/\fR\fI<path\-to\-git\-repo>\fR
642 [\fI<user>\fR\fB@\fR]\fI<host>\fR\fB:~\fR\fI<user>\fR\fB/\fR\fI<path\-to\-git\-repo>\fR
645 For local repositories, also supported by Git natively, the following syntaxes may be used:
655 \fB/path/to/repo\&.git/\fR
666 \fBfile:///path/to/repo\&.git/\fR
669 These two syntaxes are mostly equivalent, except when cloning, when the former implies \fB\-\-local\fR option\&. See \fBgit-clone\fR(1) for details\&.
671 \fBgit\fR \fBclone\fR, \fBgit\fR \fBfetch\fR and \fBgit\fR \fBpull\fR, but not \fBgit\fR \fBpush\fR, will also accept a suitable bundle file\&. See \fBgit-bundle\fR(1)\&.
673 When Git doesn\(cqt know how to handle a certain transport protocol, it attempts to use the \fBremote\-\fR\fI<transport>\fR remote helper, if one exists\&. To explicitly request a remote helper, the following syntax may be used:
683 \fI<transport>\fR\fB::\fR\fI<address>\fR
686 where \fI<address>\fR may be a path, a server and path, or an arbitrary URL\-like string recognized by the specific remote helper being invoked\&. See \fBgitremote-helpers\fR(7) for details\&.
688 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:
694 [url "\fI<actual\-url\-base>\fR"]
695 insteadOf = \fI<other\-url\-base>\fR
701 For example, with this:
707 [url "git://git\&.host\&.xz/"]
708 insteadOf = host\&.xz:/path/to/
715 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"\&.
717 If you want to rewrite URLs for push only, you can create a configuration section of the form:
723 [url "\fI<actual\-url\-base>\fR"]
724 pushInsteadOf = \fI<other\-url\-base>\fR
730 For example, with this:
736 [url "ssh://example\&.org/"]
737 pushInsteadOf = git://example\&.org/
743 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\&.
746 The name of one of the following can be used instead of a URL as \fI<repository>\fR argument:
756 a remote in the Git configuration file:
757 \fB$GIT_DIR/config\fR,
769 \fB$GIT_DIR/remotes\fR
782 \fB$GIT_DIR/branches\fR
786 All of these also allow you to omit the refspec from the command line because they each contain a refspec which git will use by default\&.
787 .SS "Named remote in configuration file"
789 You can choose to provide the name of a remote which you had previously configured using \fBgit-remote\fR(1), \fBgit-config\fR(1) or even by a manual edit to the \fB$GIT_DIR/config\fR 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:
805 The \fI<pushurl>\fR is used for pushes only\&. It is optional and defaults to \fI<URL>\fR\&. Pushing to a remote affects all defined pushurls or all defined urls if no pushurls are defined\&. Fetch, however, will only fetch from the first defined url if multiple urls are defined\&.
806 .SS "Named file in \fB$GIT_DIR/remotes\fR"
808 You can choose to provide the name of a file in \fB$GIT_DIR/remotes\fR\&. 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:
814 URL: one of the above URL formats
822 \fBPush:\fR lines are used by \fIgit push\fR and \fBPull:\fR lines are used by \fIgit pull\fR and \fIgit fetch\fR\&. Multiple \fBPush:\fR and \fBPull:\fR lines may be specified for additional branch mappings\&.
823 .SS "Named file in \fB$GIT_DIR/branches\fR"
825 You can choose to provide the name of a file in \fB$GIT_DIR/branches\fR\&. The URL in this file will be used to access the repository\&. This file should have the following format:
837 \fI<URL>\fR is required; #\fI<head>\fR is optional\&.
839 Depending on the operation, git will use one of the following refspecs, if you don\(cqt provide one on the command line\&. \fI<branch>\fR is the name of this file in \fB$GIT_DIR/branches\fR and \fI<head>\fR defaults to \fBmaster\fR\&.
847 refs/heads/<head>:refs/heads/<branch>
859 HEAD:refs/heads/<head>
866 The output of "git push" depends on the transport method used; this section describes the output when pushing over the Git protocol (either locally or via ssh)\&.
868 The status of the push is output in tabular form, with each line representing the status of a single ref\&. Each line is of the form:
874 <flag> <summary> <from> \-> <to> (<reason>)
880 If \-\-porcelain is used, then each line of the output is of the form:
886 <flag> \et <from>:<to> \et <summary> (<reason>)
892 The status of up\-to\-date refs is shown only if \-\-porcelain or \-\-verbose option is used\&.
896 A single character indicating the status of the ref:
900 for a successfully pushed fast\-forward;
905 for a successful forced update;
910 for a successfully deleted ref;
915 for a successfully pushed new ref;
920 for a ref that was rejected or failed to push; and
925 for a ref that was up to date and did not need pushing\&.
931 For a successfully pushed ref, the summary shows the old and new values of the ref in a form suitable for using as an argument to
935 \fI<old>\fR\fB\&.\&.\fR\fI<new>\fR
937 \fI<old>\fR\fB\&.\&.\&.\fR\fI<new>\fR
938 for forced non\-fast\-forward updates)\&.
940 For a failed update, more details are given:
944 Git did not try to send the ref at all, typically because it is not a fast\-forward and you did not force the update\&.
949 The remote end refused the update\&. Usually caused by a hook on the remote side, or because the remote repository has one of the following safety options in effect:
950 \fBreceive\&.denyCurrentBranch\fR
951 (for pushes to the checked out branch),
952 \fBreceive\&.denyNonFastForwards\fR
953 (for forced non\-fast\-forward updates),
954 \fBreceive\&.denyDeletes\fR
956 \fBreceive\&.denyDeleteCurrent\fR\&. See
957 \fBgit-config\fR(1)\&.
962 The remote end did not report the successful update of the ref, perhaps because of a temporary error on the remote side, a break in the network connection, or other transient error\&.
968 The name of the local ref being pushed, minus its
969 \fBrefs/\fR\fI<type>\fR\fB/\fR

975 The name of the remote ref being updated, minus its
976 \fBrefs/\fR\fI<type>\fR\fB/\fR
982 A human\-readable explanation\&. In the case of successfully pushed refs, no explanation is needed\&. For a failed ref, the reason for failure is described\&.
984 .SH "NOTE ABOUT FAST\-FORWARDS"
986 When an update changes a branch (or more in general, a ref) that used to point at commit A to point at another commit B, it is called a fast\-forward update if and only if B is a descendant of A\&.
988 In a fast\-forward update from A to B, the set of commits that the original commit A built on top of is a subset of the commits the new commit B builds on top of\&. Hence, it does not lose any history\&.
990 In contrast, a non\-fast\-forward update will lose history\&. For example, suppose you and somebody else started at the same commit X, and you built a history leading to commit B while the other person built a history leading to commit A\&. The history looks like this:
1004 Further suppose that the other person already pushed changes leading to A back to the original repository from which you two obtained the original commit X\&.
1006 The push done by the other person updated the branch that used to point at commit X to point at commit A\&. It is a fast\-forward\&.
1008 But if you try to push, you will attempt to update the branch (that now points at A) with commit B\&. This does \fInot\fR fast\-forward\&. If you did so, the changes introduced by commit A will be lost, because everybody will now start building on top of B\&.
1010 The command by default does not allow an update that is not a fast\-forward to prevent such loss of history\&.
1012 If you do not want to lose your work (history from X to B) or the work by the other person (history from X to A), you would need to first fetch the history from the repository, create a history that contains changes done by both parties, and push the result back\&.
1014 You can perform "git pull", resolve potential conflicts, and "git push" the result\&. A "git pull" will create a merge commit C between commits A and B\&.
1028 Updating A with the resulting merge commit will fast\-forward and your push will be accepted\&.
1030 Alternatively, you can rebase your change between X and B on top of A, with "git pull \-\-rebase", and push the result back\&. The rebase will create a new commit D that builds the change between X and B on top of A\&.
1044 Again, updating A with this commit will fast\-forward and your push will be accepted\&.
1046 There is another common situation where you may encounter non\-fast\-forward rejection when you try to push, and it is possible even when you are pushing into a repository nobody else pushes into\&. After you push commit A yourself (in the first picture in this section), replace it with "git commit \-\-amend" to produce commit B, and you try to push it out, because forgot that you have pushed A out already\&. In such a case, and only if you are certain that nobody in the meantime fetched your earlier commit A (and started building on top of it), you can run "git push \-\-force" to overwrite it\&. In other words, "git push \-\-force" is a method reserved for a case where you do mean to lose history\&.

1187 Update the origin repository\(cqs master branch with the dev branch, allowing non\-fast\-forward updates\&.
1188 \fBThis can leave unreferenced commits dangling in the origin repository\&.\fR
1189 Consider the following situation, where a fast\-forward is not possible:
1195 o\-\-\-o\-\-\-o\-\-\-A\-\-\-B origin/master
1203 The above command would change the origin repository to
1209 A\-\-\-B (unnamed branch)
1211 o\-\-\-o\-\-\-o\-\-\-X\-\-\-Y\-\-\-Z master
1217 Commits A and B would no longer belong to a branch with a symbolic name, and so would be unreachable\&. As such, these commits would be removed by a
1220 command on the origin repository\&.
1224 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\&.
1226 The known attack vectors are as follows:
1236 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\(cqt 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\&.)
1247 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\&.
1251 Everything below this line in this section is selectively included from the \fBgit-config\fR(1) documentation\&. The content is the same as what\(cqs found there:
1253 push\&.autoSetupRemote
1255 If set to "true" assume
1256 \fB\-\-set\-upstream\fR
1257 on default push when no upstream tracking exists for the current branch; this option takes effect with push\&.default options
1260 \fIcurrent\fR\&. It is useful if by default you want new branches to be pushed to the default remote (like the behavior of
1261 \fIpush\&.default=current\fR) and you also want the upstream tracking to be set\&. Workflows most likely to benefit from this option are
1263 central workflows where all branches are expected to have the same name on the remote\&.
1271 should take if no refspec is given (whether from the command\-line, config, or elsewhere)\&. Different values are well\-suited for specific workflows; for instance, in a purely central workflow (i\&.e\&. the fetch source is equal to the push destination),
1273 is probably what you want\&. Possible values are:
1277 \h'-04'\(bu\h'+03'\c
1284 \- do not push anything (error out) unless a refspec is given\&. This is primarily meant for people who want to avoid mistakes by always being explicit\&.
1289 \h'-04'\(bu\h'+03'\c
1296 \- push the current branch to update a branch with the same name on the receiving end\&. Works in both central and non\-central workflows\&.
1301 \h'-04'\(bu\h'+03'\c
1308 \- push the current branch back to the branch whose changes are usually integrated into the current branch (which is called
1309 \fB@\fR{upstream})\&. This mode only makes sense if you are pushing to the same repository you would normally pull from (i\&.e\&. central workflow)\&.
1314 \h'-04'\(bu\h'+03'\c
1321 \- This is a deprecated synonym for
1327 \h'-04'\(bu\h'+03'\c
1334 \- push the current branch with the same name on the remote\&.
1336 If you are working on a centralized workflow (pushing to the same repository you pull from, which is typically
1337 \fBorigin\fR), then you need to configure an upstream branch with the same name\&.
1339 This mode is the default since Git 2\&.0, and is the safest option suited for beginners\&.
1344 \h'-04'\(bu\h'+03'\c
1351 \- push all branches having the same name on both ends\&. This makes the repository you are pushing to remember the set of branches that will be pushed out (e\&.g\&. if you always push
1355 there and no other branches, the repository you push to will have these two branches, and your local
1359 will be pushed there)\&.
1361 To use this mode effectively, you have to make sure
1363 the branches you would push out are ready to be pushed out before running
1364 \fIgit push\fR, as the whole point of this mode is to allow you to push all of the branches in one go\&. If you usually finish work on only one branch and push out the result, while other branches are unfinished, this mode is not for you\&. Also this mode is not suitable for pushing into a shared central repository, as other people may add new branches there, or update the tip of existing branches outside your control\&.
1366 This used to be the default, but not since Git 2\&.0 (\fBsimple\fR
1367 is the new default)\&.
1373 If set to true, enable
1374 \fB\-\-follow\-tags\fR
1375 option by default\&. You may override this configuration at time of push by specifying
1376 \fB\-\-no\-follow\-tags\fR\&.
1381 May be set to a boolean value, or the string
1382 \fIif\-asked\fR\&. A true value causes all pushes to be GPG signed, as if
1385 \fBgit-push\fR(1)\&. The string
1387 causes pushes to be signed if the server supports it, as if
1388 \fB\-\-signed=if\-asked\fR
1390 \fIgit push\fR\&. A false value may override a value from a lower\-priority config file\&. An explicit command\-line flag always overrides this config option\&.
1396 \fB\-\-push\-option=\fR\fI<option>\fR
1397 argument is given from the command line,
1400 behaves as if each <value> of this variable is given as
1401 \fB\-\-push\-option=\fR\fI<value>\fR\&.
1403 This is a multi\-valued variable, and an empty value can be used in a higher priority configuration file (e\&.g\&. \&.\fBgit/config\fR
1404 in a repository) to clear the values inherited from a lower priority configuration files (e\&.g\&.
1405 \fB$HOME/\&.gitconfig\fR)\&.
1414 push\&.pushoption = a
1415 push\&.pushoption = b
1418 push\&.pushoption = c
1422 push\&.pushoption = b
1424 This will result in only b (a and c are cleared)\&.
1431 push\&.recurseSubmodules
1433 May be "check", "on\-demand", "only", or "no", with the same behavior as that of "push \-\-recurse\-submodules"\&. If not set,
1435 is used by default, unless
1436 \fIsubmodule\&.recurse\fR
1437 is set (in which case a
1440 \fIon\-demand\fR)\&.
1443 push\&.useForceIfIncludes
1445 If set to "true", it is equivalent to specifying
1446 \fB\-\-force\-if\-includes\fR
1449 in the command line\&. Adding
1450 \fB\-\-no\-force\-if\-includes\fR
1451 at the time of push overrides this configuration setting\&.
1456 If set to "true", attempt to reduce the size of the packfile sent by rounds of negotiation in which the client and the server attempt to find commits in common\&. If "false", Git will rely solely on the server\(cqs ref advertisement to find commits in common\&.
1461 If set to "false", disable use of bitmaps for "git push" even if
1462 \fBpack\&.useBitmaps\fR
1463 is "true", without preventing other git operations from using bitmaps\&. Default is true\&.
