 928 <div class="paragraph"><p>Everything below this line in this section is selectively included

 937         During fsck git may find issues with legacy data which
 938         wouldn&#8217;t be generated by current versions of git, and which
 939         wouldn&#8217;t be sent over the wire if <code>transfer.fsckObjects</code> was
 940         set. This feature is intended to support working with legacy
 941         repositories containing such data.
 942 </p>
 943 <div class="paragraph"><p>Setting <code>fsck.&lt;msg-id&gt;</code> will be picked up by <a href="git-fsck.html">git-fsck(1)</a>, but
 944 to accept pushes of such data set <code>receive.fsck.&lt;msg-id&gt;</code> instead, or
 945 to clone or fetch it set <code>fetch.fsck.&lt;msg-id&gt;</code>.</p></div>
 946 <div class="paragraph"><p>The rest of the documentation discusses <code>fsck.*</code> for brevity, but the
 947 same applies for the corresponding <code>receive.fsck.*</code> and
 948 <code>fetch.fsck.*</code>. variables.</p></div>
 949 <div class="paragraph"><p>Unlike variables like <code>color.ui</code> and <code>core.editor</code>, the
 950 <code>receive.fsck.&lt;msg-id&gt;</code> and <code>fetch.fsck.&lt;msg-id&gt;</code> variables will not
 951 fall back on the <code>fsck.&lt;msg-id&gt;</code> configuration if they aren&#8217;t set. To
 952 uniformly configure the same fsck settings in different circumstances,
 953 all three of them must be set to the same values.</p></div>
 954 <div class="paragraph"><p>When <code>fsck.&lt;msg-id&gt;</code> is set, errors can be switched to warnings and
 955 vice versa by configuring the <code>fsck.&lt;msg-id&gt;</code> setting where the
 956 <code>&lt;msg-id&gt;</code> is the fsck message ID and the value is one of <code>error</code>,
 957 <code>warn</code> or <code>ignore</code>. For convenience, fsck prefixes the error/warning
 958 with the message ID, e.g. "missingEmail: invalid author/committer
 959 line - missing email" means that setting <code>fsck.missingEmail = ignore</code>
 960 will hide that issue.</p></div>
 961 <div class="paragraph"><p>In general, it is better to enumerate existing objects with problems
 962 with <code>fsck.skipList</code>, instead of listing the kind of breakages these
 963 problematic objects share to be ignored, as doing the latter will
 964 allow new instances of the same breakages go unnoticed.</p></div>
 965 <div class="paragraph"><p>Setting an unknown <code>fsck.&lt;msg-id&gt;</code> value will cause fsck to die, but
 966 doing the same for <code>receive.fsck.&lt;msg-id&gt;</code> and <code>fetch.fsck.&lt;msg-id&gt;</code>
 967 will only cause git to warn.</p></div>
 968 <div class="paragraph"><p>See the <code>Fsck Messages</code> section of <a href="git-fsck.html">git-fsck(1)</a> for supported
 969 values of <code>&lt;msg-id&gt;</code>.</p></div>

 976         The path to a list of object names (i.e. one unabbreviated SHA-1 per
 977         line) that are known to be broken in a non-fatal way and should
 978         be ignored. On versions of Git 2.20 and later, comments (<em>#</em>), empty
 979         lines, and any leading and trailing whitespace are ignored. Everything
 980         but a SHA-1 per line will error out on older versions.
 981 </p>
 982 <div class="paragraph"><p>This feature is useful when an established project should be accepted
 983 despite early commits containing errors that can be safely ignored,
 984 such as invalid committer email addresses.  Note: corrupt objects
 985 cannot be skipped with this setting.</p></div>
 986 <div class="paragraph"><p>Like <code>fsck.&lt;msg-id&gt;</code> this variable has corresponding
 987 <code>receive.fsck.skipList</code> and <code>fetch.fsck.skipList</code> variants.</p></div>

 991 uniformly configure the same fsck settings in different circumstances,
 992 all three of them must be set to the same values.</p></div>
 993 <div class="paragraph"><p>Older versions of Git (before 2.20) documented that the object names
 994 list should be sorted. This was never a requirement; the object names
 995 could appear in any order, but when reading the list we tracked whether
 996 the list was sorted for the purposes of an internal binary search
 997 implementation, which could save itself some work with an already sorted
 998 list. Unless you had a humongous list there was no reason to go out of
 999 your way to pre-sort the list. After Git version 2.20 a hash implementation
1000 is used instead, so there&#8217;s now no reason to pre-sort the list.</p></div>
