New question - why it was NDEBUG, but became SQLITE_DEBUG? > Before this change, definition of pragma parser_trace was under the condition that SQLITE_DEBUG was defined, but body of the pragma was described under the condition that NDEBUG was undefined. I decided that it would be right to do the same condition for both parts of the pragma. I chose SQLITE_DEBUG because other similar pragmas use it. > >-    case PragTyp_PARSER_TRACE:{ > >-            if (zRight) { > >-                if (sqlite3GetBoolean(zRight, 0)) { > >-                    sqlite3ParserTrace(stdout, "parser: "); > >-                } else { > >-                    sqlite3ParserTrace(0, 0); > >-                } > >-            } > >-            break; > >-        } > >-#endif > > > >          /* > >           * Reinstall the LIKE and functions.
