 758 <h2 id="_description">DESCRIPTION</h2>
 759 <div class="sectionbody">
 760 <div class="paragraph"><p>Remote helper programs are normally not used directly by end users,
 761 but they are invoked by Git when it needs to interact with remote
 762 repositories Git does not support natively.  A given helper will
 763 implement a subset of the capabilities documented here. When Git
 764 needs to interact with a repository using a remote helper, it spawns
 765 the helper as an independent process, sends commands to the helper&#8217;s
 766 standard input, and expects results from the helper&#8217;s standard
 767 output. Because a remote helper runs as an independent process from
 768 Git, there is no need to re-link Git to add a new helper, nor any
 769 need to link the helper with the implementation of Git.</p></div>
 770 <div class="paragraph"><p>Every helper must support the "capabilities" command, which Git
 771 uses to determine what other commands the helper will accept.  Those
 772 other commands can be used to discover and update remote refs,
 773 transport objects between the object database and the remote repository,
 774 and update the local object store.</p></div>
 775 <div class="paragraph"><p>Git comes with a "curl" family of remote helpers, that handle various
 776 transport protocols, such as <em>git-remote-http</em>, <em>git-remote-https</em>,
 777 <em>git-remote-ftp</em> and <em>git-remote-ftps</em>. They implement the capabilities
 778 <em>fetch</em>, <em>option</em>, and <em>push</em>.</p></div>
 779 </div>
 780 </div>
 781 <div class="sect1">
 782 <h2 id="_invocation">INVOCATION</h2>
 783 <div class="sectionbody">
 784 <div class="paragraph"><p>Remote helper programs are invoked with one or (optionally) two
 785 arguments. The first argument specifies a remote repository as in Git;
 786 it is either the name of a configured remote or a URL. The second
 787 argument specifies a URL; it is usually of the form
 788 <em>&lt;transport&gt;://&lt;address&gt;</em>, but any arbitrary string is possible.
 789 The <code>GIT_DIR</code> environment variable is set up for the remote helper
 790 and can be used to determine where to store additional data or from
 791 which directory to invoke auxiliary Git commands.</p></div>
 792 <div class="paragraph"><p>When Git encounters a URL of the form <em>&lt;transport&gt;://&lt;address&gt;</em>, where
 793 <em>&lt;transport&gt;</em> is a protocol that it cannot handle natively, it
 794 automatically invokes <em>git remote-&lt;transport&gt;</em> with the full URL as
 795 the second argument. If such a URL is encountered directly on the
 796 command line, the first argument is the same as the second, and if it
 797 is encountered in a configured remote, the first argument is the name
 798 of that remote.</p></div>
 799 <div class="paragraph"><p>A URL of the form <em>&lt;transport&gt;::&lt;address&gt;</em> explicitly instructs Git to
 800 invoke <em>git remote-&lt;transport&gt;</em> with <em>&lt;address&gt;</em> as the second
 801 argument. If such a URL is encountered directly on the command line,
 802 the first argument is <em>&lt;address&gt;</em>, and if it is encountered in a
 803 configured remote, the first argument is the name of that remote.</p></div>
 804 <div class="paragraph"><p>Additionally, when a configured remote has <code>remote.&lt;name&gt;.vcs</code> set to
 805 <em>&lt;transport&gt;</em>, Git explicitly invokes <em>git remote-&lt;transport&gt;</em> with
 806 <em>&lt;name&gt;</em> as the first argument. If set, the second argument is
 807 <code>remote.&lt;name&gt;.url</code>; otherwise, the second argument is omitted.</p></div>
 808 </div>
 809 </div>
 810 <div class="sect1">
 811 <h2 id="_input_format">INPUT FORMAT</h2>
 812 <div class="sectionbody">
 813 <div class="paragraph"><p>Git sends the remote helper a list of commands on standard input, one
 814 per line.  The first command is always the <em>capabilities</em> command, in
 815 response to which the remote helper must print a list of the
 816 capabilities it supports (see below) followed by a blank line.  The
 817 response to the capabilities command determines what commands Git uses
 818 in the remainder of the command stream.</p></div>
 819 <div class="paragraph"><p>The command stream is terminated by a blank line.  In some cases
 820 (indicated in the documentation of the relevant commands), this blank
 821 line is followed by a payload in some other protocol (e.g., the pack
 822 protocol), while in others it indicates the end of input.</p></div>
 823 <div class="sect2">
 824 <h3 id="_capabilities">Capabilities</h3>
 825 <div class="paragraph"><p>Each remote helper is expected to support only a subset of commands.
 826 The operations a helper supports are declared to Git in the response
 827 to the <code>capabilities</code> command (see COMMANDS, below).</p></div>
 828 <div class="paragraph"><p>In the following, we list all defined capabilities and for
 829 each we list which commands a helper with that capability
 830 must provide.</p></div>

 987         For remote helpers that implement <em>import</em> or <em>export</em>, this capability
 988         allows the refs to be constrained to a private namespace, instead of
 989         writing to refs/heads or refs/remotes directly.
 990         It is recommended that all importers providing the <em>import</em>
 991         capability use this. It&#8217;s mandatory for <em>export</em>.
 992 </p>
 993 <div class="paragraph"><p>A helper advertising the capability
 994 <code>refspec refs/heads/*:refs/svn/origin/branches/*</code>
 995 is saying that, when it is asked to <code>import refs/heads/topic</code>, the
 996 stream it outputs will update the <code>refs/svn/origin/branches/topic</code>
 997 ref.</p></div>
 998 <div class="paragraph"><p>This capability can be advertised multiple times.  The first
 999 applicable refspec takes precedence.  The left-hand of refspecs
1000 advertised with this capability must cover all refs reported by
1001 the list command.  If no <em>refspec</em> capability is advertised,
1002 there is an implied <code>refspec *:*</code>.</p></div>
1003 <div class="paragraph"><p>When writing remote-helpers for decentralized version control
1004 systems, it is advised to keep a local copy of the repository to
1005 interact with, and to let the private namespace refs point to this
1006 local repository, while the refs/remotes namespace is used to track
1007 the remote repository.</p></div>

1013 <p>
1014         This modifies the <em>import</em> capability.
1015         The fast-import commands <em>cat-blob</em> and <em>ls</em> can be used by remote-helpers
1016         to retrieve information about blobs and trees that already exist in
1017         fast-import&#8217;s memory. This requires a channel from fast-import to the
1018         remote-helper.
1019         If it is advertised in addition to "import", Git establishes a pipe from
1020         fast-import to the remote-helper&#8217;s stdin.
1021         It follows that Git and fast-import are both connected to the
1022         remote-helper&#8217;s stdin. Because Git can send multiple commands to
1023         the remote-helper it is required that helpers that use <em>bidi-import</em>
1024         buffer all <em>import</em> commands of a batch before sending data to fast-import.
1025         This is to prevent mixing commands and fast-import responses on the
1026         helper&#8217;s stdin.
