[Pkg-nagios-devel] Bug#893723: nagvis: PHP Fatal error: Redefinition of parameter $_unused_flag

[marsupilami79]

Package: nagvis
Version: 1:1.7.10+dfsg1-3.2
Severity: grave
Tags: patch
Justification: renders package unusable

Dear Maintainer,

We installed the nagvis and nagvis-demos package. Opening nagvis in a browser lead to a HTTP/500 internal server error. In the apache error log we had the following lines:
[Wed Mar 21 16:16:45.976333 2018] [:error] [pid 28158] [client 192.168.12.252:61683] PHP Fatal error:  Redefinition of parameter $_unused_flag in /usr/share/nagvis/share/server/core/classes/objects/NagVisMapObj.php on line 247, referer: http://kameraserver/nagvis/frontend/nagvis-js/index.php?mod=Map&act=view&show=demo-germany

We followed the advice of the user hurr1c4ne on the following forum thread:
https://monitoring-portal.org/woltlab/index.php?thread/37078-php-fatal-error-redefinition-of-parameter-unused-flag-in-usr-share-nagvis-share/

This solved the problem for us. The post of hurr1c4n is as follows:
----------------------------------------------------------------------------
Have the same situation on my Ubuntu 16.04.1 Server.


I just changed the following lines
/usr/share/nagvis/share/server/core/classes/objects/NagiosService.php
:103
function queueState($_unused_flag = true) {


/usr/share/nagvis/share/server/core/classes/objects/NagVisMapObj.php
:247
public function queueState($_unused_flag = true) {


After this changes, the error messages are gone and the website works as expected.
----------------------------------------------------------------------------

This helped to get the demo maps running.

Best regards,

Jan
