+# This file implements regression tests for SQLite library.
+#
+# This file implements tests to verify that ticket #1433 has been
+# fixed.  
+#
+# The problem in ticket #1433 was that the dependencies on the right-hand
+# side of an IN operator were not being checked correctly.  So in an
+# expression of the form:
+#
+#         t1.x IN (1,t2.b,3)
+#
+# the optimizer was missing the fact that the right-hand side of the IN
+# depended on table t2.  It was checking dependencies based on the
+# Expr.pRight field rather than Expr.pList and Expr.pSelect.  
+#
+# Such a bug could be verifed using a less elaborate test case.  But
+# this test case (from the original bug poster) exercises so many different
+# parts of the system all at once, that it seemed like a good one to
+# include in the test suite. 
+#
+# NOTE:  Yes, in spite of the name of this file (tkt1443.test) this
+# test is for ticket #1433 not #1443.  I mistyped the name when I was
+# creating the file and I had already checked in the file by the wrong
+# name be the time I noticed the error.  With CVS it is a really hassle
+# to change filenames, so I'll just leave it as is.  No harm done.
