should_keep_alive函数测试  ：

返回0的条件是其中一个成立 ，否则返回1

conn->must_close =1 

conn->status_code == 401

config[ENABLE_KEEP_ALIVE], "yes") != 0 ||
header != NULL && mg_strcasecmp(header, "keep-alive") != 0

header == NULL && http_version && strcmp(http_version, "1.1"）

 

 

 

static void test_should_keep_alive(void) {  struct mg_connection conn;  struct mg_context ctx;  char req1[] = "GET / HTTP/1.1\r\n\r\n";  char req2[] = "GET / HTTP/1.0\r\n\r\n";  char req3[] = "GET / HTTP/1.1\r\nConnection: close\r\n\r\n";  char req4[] = "GET / HTTP/1.1\r\nConnection: keep-alive\r\n\r\n";  memset(&conn, 0, sizeof(conn));  conn.ctx = &ctx;  parse_http_request(req1, sizeof(req1), &conn.request_info);  ctx.config[ENABLE_KEEP_ALIVE] = "no";  ASSERT(should_keep_alive(&conn) == 0);  ctx.config[ENABLE_KEEP_ALIVE] = "yes";  ASSERT(should_keep_alive(&conn) == 1);  conn.must_close = 1;  ASSERT(should_keep_alive(&conn) == 0);  conn.must_close = 0;  parse_http_request(req2, sizeof(req2), &conn.request_info);  ASSERT(should_keep_alive(&conn) == 0);  parse_http_request(req3, sizeof(req3), &conn.request_info);  ASSERT(should_keep_alive(&conn) == 0);  parse_http_request(req4, sizeof(req4), &conn.request_info);  ASSERT(should_keep_alive(&conn) == 1);  conn.status_code = 401;  ASSERT(should_keep_alive(&conn) == 0);  conn.status_code = 200;  conn.must_close = 1;  ASSERT(should_keep_alive(&conn) == 0);}

static void test_mg_stat(void) {  static struct mg_context ctx;  struct file file;  memset(&file, 'A', sizeof(file));  ASSERT(!mg_stat(fc(&ctx), " does not exist ", &file));}

fc函数 用来返回假的连接上下文，如果连接不适合现在登录，则用于登录

// Return fake connection structure. Used for logging, if connection// is not applicable at the moment of logging.static struct mg_connection *fc(struct mg_context *ctx) {  static struct mg_connection fake_connection;  fake_connection.ctx = ctx;  return &fake_connection;}
