| 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. | |
| 53 # | |
| 54 # The trailing and leading hi-bit chars help with code which tests for | |
| 55 # isspace() to coalesce multiple spaces. | |
