 832         Internal variable used for handshaking the wire protocol. Server

 840 <dd>
 841 <p>
 842         When cloning or fetching from a partial repository (i.e., one
 843         itself cloned with <code>--filter</code>), the server-side <code>upload-pack</code>
 844         may need to fetch extra objects from its upstream in order to
 845         complete the request. By default, <code>upload-pack</code> will refuse to
 846         perform such a lazy fetch, because <code>git fetch</code> may run arbitrary
 847         commands specified in configuration and hooks of the source
 848         repository (and <code>upload-pack</code> tries to be safe to run even in
 849         untrusted <code>.git</code> directories).
 850 </p>
 851 <div class="paragraph"><p>This is implemented by having <code>upload-pack</code> internally set the
 852 <code>GIT_NO_LAZY_FETCH</code> variable to <code>1</code>. If you want to override it
 853 (because you are fetching from a partial clone, and you are sure
 854 you trust it), you can explicitly set <code>GIT_NO_LAZY_FETCH</code> to
 855 <code>0</code>.</p></div>

 865 avoid any dangerous configuration options or hooks from the repository
 866 it&#8217;s serving, making it safe to clone an untrusted directory and run
 867 commands on the resulting clone.</p></div>
