mysql - Sonar 库 4.5.4 : MySQL deadlock

Question

我正在使用带有 mysql 数据库的 sonarqube 4.5.4。

我在对我的项目运行分析时遇到了这个异常:

INFO  o.d.m.sonar.runner.RunSonarVisitor - ### Error updating database.  Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLTransactionRollbackException: Deadlock found when trying to get lock; try restarting transaction
2016-02-23 04:05:40.091Z  INFO  o.d.m.sonar.runner.RunSonarVisitor - ### The error may involve org.sonar.core.user.RoleMapper.insertGroupRole-Inline
2016-02-23 04:05:40.091Z  INFO  o.d.m.sonar.runner.RunSonarVisitor - ### The error occurred while setting parameters
2016-02-23 04:05:40.091Z  INFO  o.d.m.sonar.runner.RunSonarVisitor - ### SQL: INSERT INTO group_roles (group_id, resource_id, role)     VALUES (?, ?, ?)

这是 SHOW ENGINE INNODB STATUS 的输出:

你能帮帮我吗

Answer 1

您可以在配置中尝试 innodb_locks_unsafe_for_binlog = 1 吗？

这里是 documentation :实际上这意味着 select for update 使表锁定。关于 locks in innodb 的更多信息.

这里仍然有一些问号，但这是我的第一个想法。如果这仍然是一个问题......让我们从那个 binlog 设置开始。
