Fedora 17 Boost 1.48 Uplift
This feature brings Boost 1.48.0 to Fedora 17.
- Name: Denis Arnaud
- Email: firstname.lastname@example.org
- Targeted release: Fedora 17 (and its Feature List)
- Last updated: 2011-12-17
- Percentage of completion: 80%
- Boost 1.48.0 has been released in November 2011.
- The builds have been successful for Rawhide on Koji for both the i386 and x86_64 architectures -- darnaud (Talk - Contrib) 12:50, 20 November 2011 (UTC)
- A ticket has been open for the release engineering team to support in the rebuilding process of the dependant packages -- darnaud (Talk - Contrib) 16:28, 20 November 2011 (UTC)
- It is not up to the release engineering team to support such massive rebuilds. A specific distribution tag should be created for Boost, instead. Then, the massive rebuild would be performed against that specific tag. There has been a discussion on the Fedora-devel mailing list about that topic. -- darnaud (Talk - Contrib) 16:38, 17 December 2011 (UTC)
- Almost all the dependencies have been rebuilt on Fedora Rawhide. Only a few packages are still failing to rebuild (FTBFS bugs need to be created). See https://bugzilla.redhat.com/show_bug.cgi?id=754865 for more details.
That feature aims at synchronising the top of the Fedora tree with the current Boost upstream release. The current Fedora release is boost-1.47.0, folded into devel July 2011.
As of Fedora 13, the canonical sources used for the package switched from the official Boost release (with BJam build) to an alternate repository (with CMake build, for boost-1.41.0). That alternate repository has been deprecated and may be deleted any time soon (as of November 2011). boost-1.41.0 has been delivered from that (now deprecated) Boost-CMake repository (hosted on Gitorious), where the code base had slightly diverged from upstream.
From Fedora 14, boost-1.44.0 has been rebased on upstream, with a mere patch implementing CMake support. Moreover, there is a new Git repository reflecting those changes, hosted on GitHub (and cloned on Gitorious). That repository relies on the Ryppl project (in particular, on the Boost Subversion replicated repository), created and maintained by two talented Boost developers, namely Eric Niebler and Dave Abrahams.
The objective is now to keep delivering the latest stable Boost release for each new Fedora and RedHat releases.
- Boost package in Fedora
- Boost build status in Koji
- Fedora 16 Boost-1.47 Feature
- Fedora 15 Boost-1.46 Feature
- Fedora 14 Boost-1.44 Feature
- Fedora 13 Boost-1.41 Feature
- Boost ships with an ad-hoc build system named BJam.
Technical details are available in a Bugzilla-filed (#754865) enhancement request.
Benefit to Fedora
Syncing with upstream keeps Fedora current. This is part of regular package maintenance.
- With every new release of Boost come new components and libraries. For instance, Boost 1.48 brings Container, Locale and Move, and Boost 1.47 had already brought Chrono, Geometry, Phoenix and Ratio.
- Moreover, the existing components and libraries are enhanced with new features and bug fixes. For instance, to name a few, Asio, Chrono, Geometry, Maths, Spirit have benefited from numerous bug fixes and small evolutions.
Upstream sources for Boost releases are evaluated, along with alternate repositories. One is selected, packaged according to Fedora package conventions and cognizant of existing package practices, tested, evaluated, and then built in Koji. This is then pushed to fedora devel. Dependencies are rebuilt. The unicorns are once again happy, and can go back to drinking champagne and complaining about slow build times.
How To Test
- No special hardware is needed.
- Testing of the Boost packages themselves requires the host system to have the boost-test package installed. Testing can then be enabled at package build time by passing --with tests. Note that that testing phase should be done only once per type of architecture and distribution version.
- Once the Boost packages have been built and checked according to the previous step, testing simply consists in installing them on Fedora 16 and checking that it does not break any other package dependency.
- Expected results: all the packages depending on Boost (for instance, hugin, gnash, pingus, kdeedu or k3d) should work properly on Fedora 16.
Expected to remain largely the same.
There are a large number of dependencies for the boost package in Fedora. Following is a non-exhaustive list, collected from the first Rawhide report:
Non-completion will result in the F16 boost version, 1.47.0, being used in F17.
