(Updated Oct. 18, 2018, 11:41 p.m.)


Review request for mesos, Alexander Rukletsov, Armand Grillet, Jie Yu, and James Peach.


Changes
-------

updated to support centos 6 and 7


Summary (updated)
-----------------

Updated docker image fetcher to enforce HTTP1.0.


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 1.0. Our current HTTP parser is unable to process
HTTP 2 responses.

HTTP 1.0 was chosen instead of HTTP 1.1 as some supported linux
distributions still come with curl 7.19 which does not support the
'--http1.1' flag.

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.

For allowing all the benefits of HTTP 2 where possible, we do not
adapt any 'curl' invocations that do not attempt to parse headers.


Diffs (updated)

Changes: https://reviews.apache.org/r/69075/diff/1-2/


Testing (updated)
-------

`make check`
`sudo ./bin/mesos-tests.sh --gtest_filter="ImageAlpine/ProvisionerDockerTest.ROOT_INTERNET_CURL_SimpleCommand/2"`
on a system with curl 7.59.0 installed.


Thanks,

Till Toenshoff
