疑似swoft1.0内存泄露问题

[JoeXiong]

Q	A
Bug report?	yes/no
Feature request?	yes/no
Swoft version	1.0.0

swoft1.0版本中开启了自定义进程。使用了swoole_tracker检测内存泄露问题

1. 自定义进程内存一直不断增加

2. 泄露的信息（这个是work进程上传的信息）： `

一个是Logger.php 中 $this->messages 其他的泄露信息都是对Bean单例模式下，设置对象属性时提示的，都是类似下面的形式： public function setData(Data $data) { $this->data = $data; return $this; }

建议升级到2.0，同时这里不不会导致内存泄漏，你需要从业务排除

[JoeXiong]

@stelin 那请问怎么业务排除，应该从哪些方面去检查排除？

[JoeXiong]

之前在再检查这个问题的时候增加了一个处理：在每一次循环后都增加了一次清除 public function clean() { RequestContext::destroy(); App::getLogger()->appendNoticeLog(); } 后内存增长量基本可以忽略了，后因为App::getLogger()->appendNoticeLog();每次循环都增加了一条请求日志，垃圾日志太多，后以为是$this->messages的原因，把appendNoticeLog()替换成flushLog()，观察到现在内存增长量特别明显。现在把flushLog()还原为appendNoticeLog()内存增长量恢复正常。

现有两个问题： 1.swoole_tracker内存泄漏检测是不是不能对自定义进程监控？

2.比较了下appendNoticeLog()和flushLog()的区别 Logger.php 411行 有一行unset的操作 unset($this->profiles[$cid], $this->countings[$cid], $this->pushlogs[$cid], $this-profileStacks[$cid]); 是不是和这个有关？

[stelin]

你把 flushLog 的日志条数 调整低一点试试

[stelin]

每一条就输出
