<div class="block">Holder for a list of constants describing which bugs which have not been
fixed.
<p>You can use these constants to control the flow of your code. For example,
suppose that bug CALCITE-123 causes the "INSERT" statement to return an
incorrect row-count, and you want to disable unit tests. You might use the
constant in your code as follows:
<blockquote>
<pre>Statement stmt = connection.createStatement();
int rowCount = stmt.execute(
"INSERT INTO FemaleEmps SELECT * FROM Emps WHERE gender = 'F'");
if (Bug.CALCITE_123_FIXED) {
assertEquals(rowCount, 5);
}</pre>
</blockquote>
<p>The usage of the constant is a convenient way to identify the impact of
the bug. When someone fixes the bug, they will remove the constant and all
usages of it. Also, the constant helps track the propagation of the fix: as
the fix is integrated into other branches, the constant will be removed from
those branches.</p></div>
