Bug#878066: ganglia-webfrontend: not compatible with PHP 7

[Rike-Benjamin Schuppner]

Package: ganglia-webfrontend
Version: 3.6.1-3
Severity: normal

Hi,

The ganglia-webfrontend code contains calls to split() which is not
available in PHP 7 anymore (and therefore breaks on Debian 9) as can be
seen by accessing http://localhost/ganglia/api/host.php?action=list.

A quick fix seems to be to replace split() with explode() in
/usr/share/ganglia-webfrontend/api/host.php.

Upstream seems to have this fixed with this commit:
https://github.com/ganglia/ganglia-web/commit/c5e5831d23c6db0b04a868578680b32cb03ee952#diff-6e9d3d41e5bc04968be8f28e0b6f7a1a

- list( $_cluster, $_host ) = split( '/', $v );
+ list( $_cluster, $_host ) = str_split( '/', $v );

The patch is from 2016, but no new upstream release with this fix.

Dear Maintainer,

the bug report talks about two needed changes:
1. https://github.com/ganglia/ganglia-web/commit/c5e5831d23c6db0b04a868578680b32cb03ee952#diff-6e9d3d41e5bc04968be8f28e0b6f7a1a

- list( $_cluster, $_host ) = split( '/', $v );
+ list( $_cluster, $_host ) = str_split( '/', $v );

2. https://github.com/ganglia/ganglia-web/commit/13d426bcf66fb0f27d44847154ba2180884edcd6
- $context_metrics = "";
+ $context_metrics = array();

Both changes are in 3.7.5+debian-3, so I suggest to finally close the bug.

Thanks,
Jochen
