    Qt Quick 5.15.0 Connections 新语法

    过去的 Connection 连接某个对象的信号时是这样写的:Connections { target: authManager onError: { busyContainer.visible = false return textMeetingId.length >= 11 && textNickname.length > 0 }) message.error(result.msg) }}新的语法中可以这样写:Connections 官方文档中也介绍了一些其他好处,见:Qt官方文档如果你使用 Qt 15.5.0 版本打开了一个旧的工程并使用的是旧的写法,那么会收到一个警告:qrc:qmlAnonJoinPage.qml:54:5: QML Connections : Implicitly defined onFoo properties in Connections are deprecated.

    MySQL中的too many connections错误

    MySQL中的too many connections错误 今天中午,开发测试环境的MySQL服务报了一个too many connections的错误,从问题上看,可能是连接池被打满了,导致所有的连接都不可用了 connections2019-08-12T06:02:44.597160Z 0 Too many connections2019-08-12T06:02:44.782042Z 0 Too many connections 全部都是too many connections,幸亏是开发环境,这样的话,我们可以使用停止数据库服务的方法来进行重启,然后重新增加最大连接数,当然,这个增加的量需要考量,一般情况下,需要跟wait_timeout routinely and as many as 10,000 connections if you have many gigabytes of RAM available and the workload 除此之外,官方文档上还说了一个特点,挺好的,就是mysqld actually permits max_connections + 1 client connections.

    mongodb报错:connection refused because too many open connections: 819

    问题:发现mongodb无法连接,查看mongodb日志,出现大量的如下报错: connection refused because too many open connections: 819mongodb 2、ulimit 限制如果调大了maxConns,还是出现 too many open connections 的报错,也可能跟系统的ulimit限制有关。
