-# OVERVIEW
-#
-#   This test file attempts to verify that SQLite does not read past the 
-#   end of any in-memory buffers as a result of corrupted database page 
-#   images. Usually this happens because a field within a database page
-#   that contains an offset to some other structure within the same page
-#   is set to too large a value. A database page contains the following
-#   such fields:
-#
-#     1. The page header field that contains the offset to the first 
-#        free block of space.
-#
-#     2. The first two bytes of all but the last free block on the free-block
-#        list (the offset to the next free block).
-#
-#     3. The page header field containing the number of cells on the page
-#        (implicitly defines the offset to the final element in the cell offset
-#        array, which could potentially be off the end of the page).
-#
-#     4. The page header field containing the offset to the start of the cell
-#        content area.
-#
-#     5. The contents of the cell offset array.
-#
-#     6. The first few bytes of each cell determine the size of the cell
-#        stored within the page, and hence the offset to the final byte of
-#        the cell.
-#
-#   If any of the above fields are set to too large a value, then a buffer
-#   overread may occur. This test script creates and operates on various
-#   strategically corrupted database files to attempt to provoke such buffer
-#   overreads.
-#
-#   Very often, a buffer overread passes unnoticed, particularly in workstation
-#   environments. For this reason, this test script should be run using valgrind
-#   (or similar) in order to verify that no overreads occur.
-#
-# TEST PLAN
-# 
-#   Test cases corruptD-1.* are white-box tests. They attempt to corrupt
-#   one of the above fields, then exercise each part of the code in btree.c
-#   that uses said field.
-#   
-#   Offset variables 1, 2, 3 and 4 are all checked to make sure they
-#   will not result in buffer overruns as part of page initialization in
-#   sqlite3BtreeInitPage(). Offsets 5 and 6 cannot be tested as part of
-#   page initialization, as trying to do so causes a performance hit.
