Description static 2023-10-23 15:43:12 UTC

Description of problem:
If you try to use the setopt(CURLOPT_RESOLV, ...) option, perl core dumps.  This was tracked down awhile but seems to not be fixed upstream.  A previous commit in the upstream source for version 4.17 added #ifdef in Curl.xs for building CURLOPT_RESOLV support but the ifdef for CURLOPT_RESOLV is always false because CURLOPT_RESOLV is an enum and not a define.

Version-Release number of selected component (if applicable):


How reproducible:
Every time

Steps to Reproduce:
1. Install perl-WWW-Curl
1. Create program that uses WWW::Curl::Easy and does a setopt OPTCURL_RESOLV.  Perl immediately crashes when it hits that line.
   An example simple source program and an explenation of the problem is below...
   https://github.com/szbalint/WWW--Curl/issues/9

Additional info:
To fix it, removing the #ifdef for CURLOPT_RESOLV in the Curl.xs allows it to be compiled into perl-WWW-Curl.

It looks like besides the license change, the #ifdef was the only change for 4.17 version.  They tried to add the #ifdef for old libcurl versions that didn't support for the setopt CURLOPT_RESOLV.  I don't know that is an issue with EL8 or EL7.  Looking at the changelog for curl/libcurl, it looks like that has been in curl even in EL7.

Thanks for this.  I updated perl-WWW-Curl on my x86_64 EL 9 system with the linked test RPM in FEDORA-EPEL-2023-458b180abe.  CURLOPT_RESOLV works with the updated test RPM installed.
