比特彗星pt模式，tracker汇报最小间隔不会发送完成 min interval = 00:30

zhuxiaoying85309 · 2019年06月08日11:22

比特彗星pt模式，tracker汇报最小间隔不会发送完成，如果之前tracker返回最小间隔min interval = 00:30

复现，如果在99%进度的时候更新了tracker，然后在30秒内下载完成100%，会导致没有&event=completed参数发送到tracker

wxhere15 · 2019年06月21日16:03

代码里没有发现completed通告会受到更新间隔的限制。如果能重现的话，麻烦看看tracker日志，completed通告是没有发送，还是发送失败了呢

等下我看看，运行两分钟了还是这样，又卡new add了

现在没复现这个问题，，可能之前是网络原因导致的发送失败。那这个问题就不管他了。（不能复现的都不叫问题嗯。。）
当时没注意看这个，手动更新了几次，后来只看到网站上没有标记完成状态。

zhuxiaoying85309 · 2019年06月21日16:32

但是我发现另一个问题，，返回60个peer，比特彗星只能获取到54个，在网页中看到存在6个ipv6的用户
查看比特彗星用户列表，也没有获取到ipv6的用户ip地址，应该是解码出问题了？
直接浏览器访问tracker地址后获取数据如下，计算了下有59个peer，应该有一个是自己的ip，网站没有返回，毕竟我自己的ip 176.113.71.22不在里面

谢谢截屏反馈。BitComet支持解析tracker返回的ipv6地址peer，经测试，你提供的直接浏览器访问的数据转给BitComet能够得到59个peer地址。会不会是tracker本身有判断，直接浏览器访问的数据含ipv6地址，BitComet访问返回的数据只有ipv4？能抓包看看就更准确了。

tracker回包里有 Content-Encoding: gzip，需要gunzip解码才能看到明文

wxhere15 · 2019年06月22日14:25

你可以试试把抓包里的HTTP GET请求直接用浏览器访问tracker试试看呢。。。

zhuxiaoying85309 · 2019年06月22日14:38

请求浏览器的数据就和我上面那种样子一样啊

zhuxiaoying85309 · 2019年06月22日14:39

比如浏览器，上面就能看到这种ipv6，客户端上面没有。

浏览器访问确实会不一样，User-Agent不同
