This will save space as we don't need to keep many results in memory. It will also make it possible to do simple 'comparison' fixes like accepting the result even if a float differed in the last decimals. - Don't buffer lines from the test that you don't expect to need again. - Change 'read_line' to be faster by using the readline.cc code; We can do better than calling feof() for each character! **********************************************************************/ #define MTEST_VERSION "1.27" #include <my_global.h> #include <mysql_embed.h> #include <my_sys.h> #include <m_string.h> #include <mysql.h> #include <mysql_version.h> #include <mysqld_error.h> #include <m_ctype.h> #include <my_dir.h> #include <hash.h> #include <stdio.h> #include <stdlib.h> #include <my_getopt.h> #include <stdarg.h> #include <sys/stat.h> #include <unistd.h> #include <errno.h> #include <violite.h> #define MAX_QUERY 65536 #define PAD_SIZE 128 #define MAX_CONS 1024 #define MAX_INCLUDE_DEPTH 16 #define LAZY_GUESS_BUF_SIZE 8192 #define INIT_Q_LINES 1024 #define MIN_VAR_ALLOC 32 #define BLOCK_STACK_DEPTH 32 #define MAX_EXPECTED_ERRORS 10 #define QUERY_SEND 1 #define QUERY_REAP 2 #ifndef MYSQL_MANAGER_PORT #define MYSQL_MANAGER_PORT 23546 #endif /* Sometimes in a test the client starts before the server - to solve the problem, we try again after some sleep if connection fails the first time */ #define CON_RETRY_SLEEP 2 #define MAX_CON_TRIES 5 #define SLAVE_POLL_INTERVAL 300000 /* 0.3 of a sec */ enum {OPT_MANAGER_USER=256,OPT_MANAGER_HOST,OPT_MANAGER_PASSWD, OPT_MANAGER_PORT,OPT_MANAGER_WAIT_TIMEOUT, OPT_SKIP_SAFEMALLOC, OPT_SSL_SSL, OPT_SSL_KEY, OPT_SSL_CERT, OPT_SSL_CA, OPT_SSL_CAPATH, OPT_SSL_CIPHER};
