Changes
-------
Updated again to address recent comment by James - thanks a bunch!
Summary (updated)
-----------------
Updated docker image fetcher to enforce HTTP 1.1.
Bugs: MESOS-8907
https://issues.apache.org/jira/browse/MESOS-8907
Repository: mesos
Description (updated)
-------
Modifies the 'curl' invocation that is returning an http::Response,
locking it into HTTP 1.1. Our current HTTP parser is unable to process
HTTP 2 responses.
With the advent of curl 7.47, HTTPS connections are being enforced
towards HTTP 2 rather aggressively. As a result, our image fetcher
fails when recent curl versions are being used for pulling images from
a registry that supports HTTP 2.
HTTP 1.1 is chosen as long as the underlying curl supports the
'--http1.1' flag. If curl is old enough to not support that flag, we
can deduct that it will not enforce HTTP 2 and therefor need no
further actions.
For allowing all the benefits of HTTP 2 where possible, we do not
adapt any 'curl' invocations that do not attempt to parse headers.
