本篇内容介绍了“怎么解决MySQL中InnoDB: Failing assertion: format != 0错误”的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!
1、MySQL版本5.7.19,OS是MAC OSX在删除表空间时,出现如下错误
[root@localhost][(none)]> drop tablespace ts1;
ERROR 2013 (HY000): Lost connection to MySQL server during query
2、查看error.log日志,看样子有点像是BUG
2018-04-09 16:00:21 0x700007f04000 InnoDB: Assertion failure in thread 123145435496448 in file ha_innodb.cc line 20927 InnoDB: Failing assertion: format != 0 InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://bugs.mysql.com. InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html InnoDB: about forcing recovery. 08:00:21 UTC - mysqld got signal 6 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=8388608 read_buffer_size=16777216 max_used_connections=1 max_threads=512 thread_count=2 connection_count=1 It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 25180932 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.
3、查看ha_innodb.cc源码的20927行
void ib_senderrf( THD* thd, ib_log_level_t level, ib_uint32_t code, ...) {
va_list args;
char* str = NULL; const char* format = innobase_get_err_msg(code); ut_a(thd != 0); ut_a(format != 0);
va_start(args, code);
#ifdef _WIN32
int size = _vscprintf(format, args) + 1; if (size > 0) {
str = static_cast<char*>(malloc(size));
} if (str == NULL) {
va_end(args); return; }
str[size - 1] = 0x0;
vsnprintf(str, size, format, args);
#elif HAVE_VASPRINTF
int ret;
ret = vasprintf(&str, format, args); if (ret < 0) {
va_end(args); return; }
#else str = static_cast<char*>(malloc(BUFSIZ)); if (str == NULL) {
va_end(args); return; }
my_vsnprintf(str, BUFSIZ, format, args);
#endif Sql_condition::enum_severity_level l;
l = Sql_condition::SL_NOTE; switch (level) { case IB_LOG_LEVEL_INFO: break; case IB_LOG_LEVEL_WARN:
l = Sql_condition::SL_WARNING; break; case IB_LOG_LEVEL_ERROR: my_printf_error(code, "%s", MYF(0), str); break; case IB_LOG_LEVEL_FATAL:
l = Sql_condition::SEVERITY_END; break;
} if (level != IB_LOG_LEVEL_ERROR) {
push_warning_printf(thd, l, code, "InnoDB: %s", str);
}
va_end(args);
free(str); if (level == IB_LOG_LEVEL_FATAL) {
ut_error;
}
}
