高并发请求下，日志出现冲突

[winner7776]

并发请求下，日志出现被截断的情况，请问是配置问题吗？

[Neeke]

能提供一个样例吗？

SeasLog :: warning("client_log=" . $param);
将客户端的所有请求内容写入文件中。
文件中出现类似如下的日志

日志的内容显示上一次日志未输出完，后一个日志就插入到中间。

@xuhaifeng666 在写入日志时出于性能考虑，使用的是乐观锁。
请开启buffer进行尝试，会有改善

[winner7776]

seaslog.use_buffer = 1
seaslog.buffer_size= 100
buffer是有开启的

@xuhaifeng666 高并发写触发日志截断的 demo 代码帮给个

[winner7776]

$param = file_get_contents("php://input");
$param = urldecode($param);
if(!empty($param)){
SeasLog :: warning("client_log=" . $param);
}

我的代码就是收到请求打印内容，当post数据过大时就会出现日志截断的情况。

[hi-man]

$param = file_get_contents("php://input");
$param = urldecode($param);
if(!empty($param)){
SeasLog :: warning("client_log=" . $param);
}

我的代码就是收到请求打印内容，当post数据过大时就会出现日志截断的情况。

复现出body较大时，客户端分片传输，服务端收到多个请求，样例代码只记录第一个请求，SeasLog正常记录，后续数据被样例代码丢弃（http 400)
