6: # This file implements regression tests for SQLite library. The focus
7: # of this script is testing isspace/isalnum/tolower problems with the
8: # FTS2 module. Unfortunately, this code isn't a really principled set
9: # of tests, because it is impossible to know where new uses of these
10: # functions might appear.

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

54: # The trailing and leading hi-bit chars help with code which tests for
55: # isspace() to coalesce multiple spaces.
