+# This file implements regression tests for SQLite library.  The focus
+# of this script is testing isspace/isalnum/tolower problems with the
+# FTS1 module.  Unfortunately, this code isn't a really principled set
+# of tests, because it's impossible to know where new uses of these
+# functions might appear.

+# The snippet-generation code has calls to isspace() which are sort of
+# hard to get to.  It finds convenient breakpoints by starting ~40
+# chars before and after the matched term, and scanning ~10 chars
+# around that position for isspace() characters.  The long word with
+# embedded hi-bit chars causes one of these isspace() calls to be
+# exercised.  The version with a couple extra spaces should cause the
+# other isspace() call to be exercised.  [Both cases have been tested
+# in the debugger, but I'm hoping to continue to catch it if simple
+# constant changes change things slightly.
+#
+# The trailing and leading hi-bit chars help with code which tests for
+# isspace() to coalesce multiple spaces.
