# Open Build Service 2.3
#
Please read the README.SETUP file for initial installation
instructions or use the OBS Appliance from
http://en.opensuse.org/Build_Service/OBS-Appliance
There is also an install medium with installs OBS on hard disc now.
README.UPDATERS file has informations for updaters.
OBS Appliance users who have setup their LVM can just replace
their appliance image without data loss. The migration will
happen automatically.
Main Features
=============
The main topic of OBS 2.3 is to deliver a number of features to allow
product maintenance handling with OBS. No external build or tracking tool
is needed to do the typical maintenance workflow of a distribution team.
The usage of these features are documented in the OBS book:
http://doc.opensuse.org/products/draft/OBS/obs-reference-guide_draft/
OBS 2.3 comes also with a feature which was planned for the not released
OBS 2.2 version. New created projects can set to hidden. That means no source
or binary read access is possible. Please read the following for details:
To be considered regarding read access checks
=============================================
* "access" flag is hiding and protecting entire project. This includes binaries
and sources. It can only be used at project creation time and can just be
globally enabled (aka make it public again) afterwards.
This flag can only be used on projects.
NOTE: there is no support in request system to hide projects which should not
be visible. Don't create requests if you don't want to expose them.
* "sourceaccess" flag is hiding the sources to non maintainers, this includes also debug packages
in case the distribution is supporting this correctly.
This flag can also only be used at package creation time. There is no code
yet which is checking for possible references to this package.
This flag can be used on projects or packages.
* "downloadbinary" permission still exists like before. However, unlike "access"
and "sourceaccess" this is not a security feature. It is just a convinience feature, which
makes it impossible to get the binaries via the API directly. But it still possible
to get the binaries via build time in any case.
Security aspects
================
Former OBS releases lack protection against XSS attacks. Esp. public instances
should update to OBS 2.3, which is using rails plugins to protect against XSS
attempts. This fixes (CVE-2011-0462).
Building in "chroot" environments is known to be unsecure. XEN and KVM is considered to
be a secure environment. However KVM is known to be unstable, it leads to build
failures.
Apache & mod_rails switch
=========================
Former OBS versions used lighttpd as default web server. We have switched to
apache with mod_rails (known as passenger) as default web server.
We have also added an mod_xforward apache module to allow unloading the rails
stack with long running requests to the backend.
Please note that current apache2 versions have a known bug which cuts the http
headers regardless to it's configuration. Please use apache2 from openSUSE:Tools
project to get this fixed for now.
Also the patched version of rubygem-passenger from openSUSE:Tools project is recommended.
Known Regressions to 2.1:
=========================
* none yet
Features:
=========
* web interface improvements:
- package filtering
- Generic authentification proxy support
- delete request dialogs
- request and review handling improvements
- social features, i.e. show other user's projects and requests
* api
- review of requests by project or package maintainers is possible now (FATE #310806)
- better Cross-Site Scripting (XSS) protection
- larger number of request handling improvements
* backend:
- dispatcher got rewritten having a more clever sort order based on defined
priorities and the trigger reason.
Changes:
========
* web interface
- bug reporting for projects/packages is only possible if a bugowner is set
- XSS protection plugins are used now (CVE-2011-0462)
* api
- It was not possible so far to create submit requests from packages where no write access exists.
This is possible now, but the source package maintainer will get asked for review the request.
- the route /group/$GROUP is showing correct xml description and no directory anymore
* new source service handling
- Source services do not generate an extra commit for the result. Instead they work like
source links, this means the generated files become visible with expand=1 parameter.
- The state of the service is visible via serviceinfo element in package file list.
* The scheduler is excluding the link information on calculating rebuilds. This means it triggers
only builds when the merged source has changed.
NOTE: as a side effect all linked packages will get rebuild due to changed md5sum after 2.3 update.
* The backend is only accepting write access from the localhost by default. Build results can be
still delivered from any host. This can be changed in BSConfig.pm
* The scheduler architectures of armvXel and armv7hl are recommended to be renamed to armvXl.
Package architectures can be kept to arm7hl or armv8l via the "Target: " tag in project config.
Deprecated:
===========
The following calls have been marked as deprecated, they will get removed in OBS 3.0
* api
- /person/$LOGIN/group -> use /group?login=$LOGIN instead
Requirements:
=============
* The OBS server should not run on a system with less than 2GB memory.
4GB is recommended, esp. when the same system is also building packages.
* Use osc 0.132 or later to get access to the new features.
* Usage of Ruby on Rails version 2.3.11 is recommended.
