dfget --limit doesn't work

[ismewen]

Bug report:

dfget --limit doesn't work， the download speed does not follow the specified speed。

Expected behavior:

The download speed follow the specified speed

How to reproduce it:

./dfget --limit 1G -u http://10.190.113.78:8001/1gfile.tgz -b
./dfget --limit 10M -u http://10.190.113.78:8001/1gfile.tgz -b

Environment:

• Dragonfly version: 2.0.3
• OS: centos
• Kernel (e.g. uname -a): SMP Wed Sep 29 11:01:45 CST 2021 x86_64 x86_64 x86_64 GNU/Linux
• Others:

flag and config do not agree on the name, so the limit is not passed in
I will fix it

[1037husterljx]

• The command line flag limit should be ratelimit
• ratelimit deserialization failed, change type to solve
• When ratelimit limit is too low, below the download size of the slice, otherwise it will fail back to the source
• The ratelimit rate described by -b is limited and cannot describe the speed limit of p2p network
