|
|
# Proc [do_matchinfo_test] is used to test the FTSX matchinfo() function.
|
|
#
|
|
# The first argument - $tn - is a test identifier. This may be either a
|
|
# full identifier (i.e. "fts3matchinfo-1.1") or, if global var $testprefix
|
|
# is set, just the numeric component (i.e. "1.1").
|
|
#
|
|
# The second argument is the name of an FTSX table. The third is the
|
|
# full text of a WHERE/MATCH expression to query the table for
|
|
# (i.e. "t1 MATCH 'abc'"). The final argument - $results - should be a
|
|
# key-value list (serialized array) with matchinfo() format specifiers
|
|
# as keys, and the results of executing the statement:
|
|
#
|
|
# SELECT matchinfo($tbl, '$key') FROM $tbl WHERE $expr
|
|
#
|
|
# For example:
|
|
#
|
|
# CREATE VIRTUAL TABLE t1 USING fts4;
|
|
# INSERT INTO t1 VALUES('abc');
|
|
# INSERT INTO t1 VALUES('def');
|
|
# INSERT INTO t1 VALUES('abc abc');
|
|
#
|
|
# do_matchinfo_test 1.1 t1 "t1 MATCH 'abc'" {
|
|
# n {3 3}
|
|
# p {1 1}
|
|
# c {1 1}
|
|
# x {{1 3 2} {2 3 2}}
|
|
# }
|
|
#
|
|
# If the $results list contains keys mapped to "-" instead of a matchinfo()
|
|
# result, then this command computes the expected results based on other
|
|
# mappings to test the matchinfo() function. For example, the command above
|
|
# could be changed to:
|
|
#
|
|
# do_matchinfo_test 1.1 t1 "t1 MATCH 'abc'" {
|
|
# n {3 3} p {1 1} c {1 1} x {{1 3 2} {2 3 2}}
|
|
# pcx -
|
|
# }
|
|
#
|
|
# And this command would compute the expected results for matchinfo(t1, 'pcx')
|
|
# based on the results of matchinfo(t1, 'p'), matchinfo(t1, 'c') and
|
|
# matchinfo(t1, 'x') in order to test 'pcx'.
