Description andrew-beck 2024-04-12 14:36:19 UTC

Description of problem:
The RMSPEC for mapserver (https://src.fedoraproject.org/rpms/mapserver/blob/epel9/f/mapserver.spec) has an install requirement on the "httpd" package that it does not need.
It also has a matching build requirement requirement of "httpd-devel" it does not need.

This cause it to fail to install if the machine is using "Easy Apache" package.

The mapserv binary in this package is a standalone cgi binary it does not need "httpd" to run or "httpd-devel" to build as configured in the package.

The package as built by the RPMSPEC taken from the build log (https://kojipkgs.fedoraproject.org//packages/mapserver/8.0.0/3.el9/data/logs/x86_64/build.log) of hpackage build https://koji.fedoraproject.org/koji/buildinfo?buildID=2082450

show that mapserver was build with the option
"Apache Module (Experimental): disabled"

This is an experimental non default build option and is the only part of Mapserver that require the Apache "httpd" package (https://github.com/MapServer/MapServer/blob/branch-8-0/apache/CMakeLists.txt)

Thus as the RPMSPEC does not build mapserver with any option that requires "httpd" they should be removed from the RPMSPEC

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


How reproducible:

Setup an Enterprise Redhat based machine like AlmaLinux 9
Install Easy Apache 4 (and cPanel)
Make sure the necessary EPEL repos are enabled 
dnf install mapserver


Actual results:
Error:
 Problem: problem with installed package ea-apache24-2.4.59-1.1.1.cpanel.x86_64
  - package ea-apache24-2.4.59-1.1.1.cpanel.x86_64 from @System conflicts with httpd-mmn provided by httpd-core-2.4.57-5.el9.x86_64 from appstream

  - package httpd-2.4.57-5.el9.x86_64 from appstream requires httpd-core = 2.4.57-5.el9, but none of the providers can be installed
  - package mapserver-8.0.0-3.el9.x86_64 from epel requires httpd, but none of the providers can be installed
  - conflicting requests
(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)


Expected results:
The package to install

Additional info:
Removing the lines from the RPMSPEC:-

Requires:       httpd
BuildRequires:  httpd-devel

Results in successful build and package.
The package then installs on a system without the "httpd" package
Running the "mapserv" binary produced the normal html output.

Comment 1 Sandro Mani 2025-03-23 12:51:13 UTC

This is not a mapserver package bug, but the result of httpd not being installable due to other conflicts.

Comment 2 andrew-beck 2025-03-23 17:00:15 UTC

This is most definitely a Bug is the mapserver package.

Mapserver default build has no dependencies on httpd, therefore why does it need httpd to be installed to install the mapserver package?

The reason why I was installing mapserver without a httpd package has no relevance other than it highlighted the redundant dependency on httpd.

The httpd package does not provide any of these libraries.

The mapserv binary has a commandline interface, e.g.
sh-5.1# ./mapserv -h
Usage: mapserv [--help] [-v] [-nh] [QUERY_STRING=value] [PATH_INFO=value]
                [-conf filename]

Options :
  -h, --help              Display this help message.
  -v                      Display version and exit.
  -nh                     Suppress HTTP headers in CGI mode.
  -conf filename          Filename of the MapServer configuration file.
  QUERY_STRING=value      Set the QUERY_STRING in GET request mode.
  PATH_INFO=value         Set the PATH_INFO for an API request.

Yes it is common to have an Http server execute the standalone mapserv binary inside it's cgi environment, just it not a requirement to actually do this.
