Package: drupal6 Version: 6.22-1~bpo60+1 Severity: normal
Summary: ======================================================================= The deployment of drupal6 in a production environment, that uses php5-fpm and nginx in different servers, is currently cumbersome due to dependencies on apache2 or httpd. Suggested Fix: ======================================================================= Include php5-fpm as a third option along with apache2 and httpd, and list them as Recommends and not as Dependencies. Detailed explanation and Rationale: ======================================================================= The deployment of drupal6 in a server that will run it using php5-fpm is cumbersome due to the dependencies on apache2 or httpd. The application server doesn't need to run that software because it uses a fastCGI daemon to attend the queries that receives from the front-end servers. Due to the dependencies referred, nginx was installed and deactivated on the application server. A somewhat weird behavior of aptitude also required the installation of apache2 even when nginx was already installed and it provides httpd. Apache2 and related packages were removed withotu problems as they were unnecesary. Those dependencies are unchanged in testing and unstable. php5-fpm is available in those releases, and probably soon in squeeze-backports. Therefore dependencies that allow a more straightforward deployment of drupal6 in a production environment that uses php5-fpm, or some other application engine, are desirable. In order to achieve that, it could be considered the inclusion of php5-fpm as a third option along with apache2 and httpd. It could also be considered the inclusion of those three packages as recommendations rather that dependencies, in order to allow an straightforward deployment of some other software stack, for instance one that uses uWSGI ( currently available in testing ) as application engine. The use of advanced application engines and frontends like uWSGI and nginx is very desirable in production environments, therefore it looks appropriate to just list as drupal6 recommends some packages that provide front-end, application containers and back-ends. Currently, the package lists as recommends some back-end software. The front-ends or application containers currently listed as dependencies should also be there. In that way, a simple "aptitude install drupal6" would continue to provide a fully functional installation for development or review purposes, but it would be also possible to use "aptitude --without-recommends drupal6" for a deployment in an environment that has a different software stack or a layered design. A common and recommended practice on the web portals is the deployment of http and application daemons on different clusters of servers. In our case, we are currently setting up a cluster of application servers that will host a web portal. Some of those servers will run drupal6 using php5-fpm. The publishing stack contains http servers based on nginx at the front-end layer, application servers based on php5-fpm and django-fastcgi (pending to be upgraded to uwsgi), and a back-end layer based on a postgresql database cluster and a NFS file server (pending to be upgraded to a clustered filesystem). The deployment of php5-fpm on squeeze required a backport of the 5.4.0-3 version and that was straightforward to build locally. In http://lists.debian.org/debian-backports-changes/2012/03/msg00803.html is reported that the maintainer, or another uploader, has already sent a package that it's currently at the review stage in debian-backports, so it could be expected to be available at the repositories in a short term. Therefore the suggested change on dependencies would even be more appropriate. -- System Information: Debian Release: 6.0.4 APT prefers stable APT policy: (990, 'stable'), (500, 'stable-updates') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/1 CPU core) Locale: LANG=es_VE.UTF-8, LC_CTYPE=es_VE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages drupal6 depends on: ii curl 7.21.0-2.1+squeeze2 Get a file from an HTTP, HTTPS or ii dbconfig-common 1.8.46+squeeze.0 common framework for packaging dat ii debconf [debconf-2.0 1.5.36.1 Debian configuration management sy ii exim4-daemon-light [ 4.72-6+squeeze2 lightweight Exim MTA (v4) daemon ii nginx [httpd] 0.7.67-3+squeeze2 small, but very powerful and effic ii php5 5.4.0-3~bpo60+1 server-side, HTML-embedded scripti ii php5-gd 5.4.0-3~bpo60+1 GD module for php5 ii php5-pgsql 5.4.0-3~bpo60+1 PostgreSQL module for php5 ii postgresql-client 9.1+124~bpo60+1 front-end programs for PostgreSQL ii postgresql-client-9. 9.1.3-2~bpo60+1 front-end programs for PostgreSQL ii wwwconfig-common 0.2.1 Debian web auto configuration Versions of packages drupal6 recommends: pn mysql-server | postgresql <none> (no description available) drupal6 suggests no packages. -- debconf information excluded
