# 2007 March 28 # # The author disclaims copyright to this source code. # #************************************************************************* # 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. # # $Id: fts3al.test,v 1.2 2007/12/13 21:54:11 drh Exp $ # set testdir [file dirname $argv0] source $testdir/tester.tcl # If SQLITE4_ENABLE_FTS3 is defined, omit this file. ifcapable !fts3 { finish_test return } # Tests that startsWith() (calls isspace, tolower, isalnum) can handle # hi-bit chars. parseSpec() also calls isalnum here. do_test fts3al-1.1 { execsql "CREATE VIRTUAL TABLE t1 USING fts3(content, \x80)" } {} # Additionally tests isspace() call in getToken(), and isalnum() call # in tokenListToIdList(). do_test fts3al-1.2 { catch { execsql "CREATE VIRTUAL TABLE t2 USING fts3(content, tokenize \x80)" } sqlite4_errmsg $DB } "unknown tokenizer: \x80" # Additionally test final isalnum() in startsWith(). do_test fts3al-1.3 { execsql "CREATE VIRTUAL TABLE t3 USING fts3(content, tokenize\x80)" } {} # The snippet-generation code has calls to isspace() which are sort of # hard to get to. It finds convenient breakpoints by starting ~40 # chars before and after the matched term, and scanning ~10 chars # around that position for isspace() characters. The long word with # embedded hi-bit chars causes one of these isspace() calls to be # exercised. The version with a couple extra spaces should cause the # other isspace() call to be exercised. [Both cases have been tested # in the debugger, but I'm hoping to continue to catch it if simple # constant changes change things slightly. # # The trailing and leading hi-bit chars help with code which tests for # isspace() to coalesce multiple spaces. # # UPDATE: The above is no longer true; there is no such code in fts3. # But leave the test in just the same. # set word "\x80xxxxx\x80xxxxx\x80xxxxx\x80xxxxx\x80xxxxx\x80xxxxx\x80" set phrase1 "$word $word $word target $word $word $word" set phrase2 "$word $word $word target $word $word $word" db eval {CREATE VIRTUAL TABLE t4 USING fts3(content)} db eval "INSERT INTO t4 (content) VALUES ('$phrase1')" db eval "INSERT INTO t4 (content) VALUES ('$phrase2')" do_test fts3al-1.4 { execsql {SELECT rowid, length(snippet(t4)) FROM t4 WHERE t4 MATCH 'target'} } {1 241 2 247} finish_test
