Filedownloader: 所有任务全部卡在 pending

[BinarySatan]

当我下载文件时，有时会突然 不走progress， 这时如果 pause reuse start .. 有时会一直卡在 pending, 如果卡在pending的话， 这时候不论开启几个任务，全部都是卡在pending状态

[rantianhua]

希望能提供 FileDownloader 的日志，这样能更清楚更快地解决问题。

一直停在这了, 并且也没有.temp文件创建， 跟了下代码，最后好像线程池里面的 run没有跑..不太确定.

[rantianhua]

通过分析你的日志，前面的下载一直是正常进行的，progress 也是一直在回调者，所以不清楚你说的突然不走 progress 回调是怎么回事？你想要的 progress 回调是怎样的？（比如频率）。

---

当 task 进入 pending 状态，下一步是进行一次很轻量的连接获取文件的大小。从你给的日志看，还没有连接结果返回，所以我推测是连接还未完成。完全卡主应该不会出现的，因为发生任何问题都会在 error 进行回调，内部不会有死循环的逻辑。而且在你第一段日志里，中间出现了 connect reset by peer 的错误，所以我怀疑后面你再重新开启任务建立连接的时候，也有可能有问题。关于 connect reset by peer 的问题，已经详细回答你了。综上，你再排除下连接的问题，比如你可以用 Charles/Wireshark 进行抓包，看看连接是否一直正常。

[BinarySatan]

这个是我针对FileDownloadMessenger 进行的日志截取， 关掉过滤的话， 最后会有System.out Close OKHttp的 显示。然后就不在进行progress回调了，但是getStatus状态还是3。 这种情况下，我等了能有5 6分钟 都不动。 而且我下载别的任务 也全部卡在了pending,觉得这是不应该的。 我自己在看看，跟踪下日志吧。

[rantianhua]

那这种情况下你可对 FetchDataTask 的 run 方法进行断点，读取 stream 流的操作就在这里面，可以通过在这里断点判断下载任务是否还在继续。或者更直观一点用 Charles 抓包，可以持续观察 response 里 body 大小的变化。

[BinarySatan]

开启所有任务都是pending状态， FetchDataTask 的 run方法没有跑。

[rantianhua]

@BinarySatan 可以提供你有问题的 Demo 的 Github 地址吗？然后我按照你目前提供的信息找下问题，在目前 FileDownloader 的 Demo 里面没有遇到过这种情况。

[BinarySatan]

行，我弄个demo。

[BinarySatan]

https://github.com/BinarySatan/FileDownDemo 你好这是项目地址，现在有的问题如下:
1,进度回滚
2,总是在66% 会卡.
3,只要一个任务一直pending,所有任务都会pending.

问题需要多测几次 就会出来。

[rantianhua]

好的，我会调试你的 Demo 看看具体问题。

[BinarySatan]

谢谢。

[rantianhua]

已经试过了你的 Demo ，目前发现的问题是，下载的过程中经常出现 ProtocolException: unexpected end of stream 这个错误。我用 Charles 抓包看了下连接，发现对于每一个连接，在 request 里面 range 指定需要下载的大小为 15M 左右，但实际上 response 的 body 里只接收到几百 K 连接就断掉了，这是问题所在。这个问题应该是发生在后端，为什么没有返回请求里指定多的数据就关掉了连接，造成 ProtocolException ？

当然也有可能是后端做了限制，即一个请求最多请求几百 K 的数据。基于这个假设，那么在断点下载的基础上，增加重试次数应该最终能下载完整个文件。为了验证，索性在你的 demo 里把重试次数改为 100 ，然后再试一下，发现果然可以正常下载完整个文件。

后来我把你 Demo 里第一个下载链接放在 Chrome 里进行下载，发现也是同样的情况，得重新加载好几次才能最终加载出整个文件。

[rantianhua]

不过你所描述的突然不走 progress 的问题我依然没有在你的 Demo 里面复现

[BinarySatan]

我这试了一下，应该不是后端做限制的问题，因为我这次可能下载停了，下次可能就不停，所以不确定是哪的问题 而且 就算改成100, 也会在某个点直接停下来不走了(需要手动pause 在 重新 createImpl .start，
而这步操作之后，可能继续下载，也有小概率一直pending,这时在开启别的任务也都是pending状态)
问题可能是基于后台断开链接才出现的吧,不太确定。
