[jira] [Updated] (MESOS-4853) Considering using libcurl multi interface to implement 'curl' in Mesos.

     [ https://issues.apache.org/jira/browse/MESOS-4853?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jie Yu updated MESOS-4853:
--------------------------
    Description: 
Reference:
https://curl.haxx.se/libcurl/c/libcurl-multi.html

Currently, some URI fetchers rely on 'curl' command directly (using subprocess). This is not ideal. The libcurl easy interface is blocking, so it does not compose well with our async environment. However, the multi interface seems to be suitable for our async environment. The tricky part is that we need to hook the fd selecting logic with our underlying libev/libevent runtime, but this should be doable.
