Description Martin Kyral 2017-01-20 08:57:51 UTC

The same problem is with perl-libwww-perl-6.05-2.el7. This bug shall be fixed to prevent regressions upon upgrade from RHEL 6.9 to RHEL 7.x.

+++ This bug was initially created as a clone of Bug #1400632 +++

Description of problem:

With perl-libwww-perl-5.883-2 the $env{https_proxy} variable ceases to be honoured


Version-Release number of selected component (if applicable):
perl-libwww-perl-5.883-2 

How reproducible:
Always

Steps to Reproduce:
1. check soap_test.pl script

Actual results:
Never connects to webproxy

Expected results:
Should connect to web proxy

Additional info:
Verified via Wireshark & tcpdump that the server never attempts to use the web proxy

--- Additional comment from Petr Pisar on 2016-12-02 06:46:53 EST ---

How to test:

(1) Use LWP::UserAgent without env_proxy option to connect to an HTTPS server while https_proxy environment variable is set to a HTTP proxy server and verify the TCP connection is opened to the proxy server, not to the HTTPS server. Example:

$ https_proxy=http://localhost:80 perl -e 'use LWP::UserAgent; LWP::UserAgent->new->get(q{https://localhost:443/})'

Before: There it connects to localhost:443.
After: It connects to localhost:80.

(2) Repeat the same with HTTPS_PROXY with the same results as in (1).

(3) Specify https_proxy without the "http://" schema. It should also work.

Please note that this applies to HTTPS proxy. Not to HTTP (http_proxy or HTTP_PROXY) variables. Please also note that it does not apply to LWP::UserAgent->new() invocations that have env_proxy argument.

Comment 2 Petr Pisar 2017-01-20 09:50:47 UTC

No, this feature will not be implemented in RHEL-7 or later.

The RHEL-6 bug #1400632 is to restore compatibility with previous RHEL-6 code because we changed default HTTPS implementation in the middle of RHEL-6 life cycle.

RHEL-7 uses the new HTTPS implementation as default since the beginning and is in line with upstream intention to stop using the old HTTPS implementation.
