# This file implements regression tests for SQLite library. The focus
|
|
# of this script is testing isspace/isalnum/tolower problems with the
|
|
# FTS3 module. Unfortunately, this code isn't a really principled set
|
|
# of tests, because it is 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.
|
|
#
|
|
# UPDATE: The above is no longer true; there is no such code in fts3.
|
|
# But leave the test in just the same.
