84: #--------------------------------------------------------------------------
85: # Proc [do_matchinfo_test] is used to test the FTSX matchinfo() function.
86: #
87: # The first argument - $tn - is a test identifier. This may be either a
88: # full identifier (i.e. "fts3matchinfo-1.1") or, if global var $testprefix
89: # is set, just the numeric component (i.e. "1.1").
90: #
91: # The second argument is the name of an FTSX table. The third is the
92: # full text of a WHERE/MATCH expression to query the table for
93: # (i.e. "t1 MATCH 'abc'"). The final argument - $results - should be a
94: # key-value list (serialized array) with matchinfo() format specifiers
95: # as keys, and the results of executing the statement:
96: #
97: # SELECT matchinfo($tbl, '$key') FROM $tbl WHERE $expr
98: #
99: # For example:
100: #
101: # CREATE VIRTUAL TABLE t1 USING fts4;
102: # INSERT INTO t1 VALUES('abc');
103: # INSERT INTO t1 VALUES('def');
104: # INSERT INTO t1 VALUES('abc abc');
105: #
106: # do_matchinfo_test 1.1 t1 "t1 MATCH 'abc'" {
107: # n {3 3}
108: # p {1 1}
109: # c {1 1}
110: # x {{1 3 2} {2 3 2}}
111: # }
112: #
113: # If the $results list contains keys mapped to "-" instead of a matchinfo()
114: # result, then this command computes the expected results based on other
115: # mappings to test the matchinfo() function. For example, the command above
116: # could be changed to:
117: #
118: # do_matchinfo_test 1.1 t1 "t1 MATCH 'abc'" {
119: # n {3 3} p {1 1} c {1 1} x {{1 3 2} {2 3 2}}
120: # pcx -
121: # }
122: #
123: # And this command would compute the expected results for matchinfo(t1, 'pcx')
124: # based on the results of matchinfo(t1, 'p'), matchinfo(t1, 'c') and
125: # matchinfo(t1, 'x') in order to test 'pcx'.
