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.

25 # hi-bit chars. parseSpec() also calls isalnum here.

31 # in tokenListToIdList().

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.
