Development/Software_Engineering_Framework


This page is intended to be a summary of the tools and processes used by the KDE project for Software Engineering tasks, i.e. everything around coding work. This includes bugfixing, review, testing, documentation, requirements etc.

The current tool used by KDE should be listed along with the extent of its use, known alternatives, and advantages/disadvantages.

Subversion is currently used for source control management in KDE on a server hosted in Frankfurt. A separate server is used for access to the read-only mirror anonsvn.kde.org.

There is begun migrating to Git, see Move to Git. A guide to KDE Git infrastructure can be found on the Git.kde.org Manual.

Build System

CMake is the build tool currently used by KDE. It is Free Software developed by kitware inc and available on multiple platforms supported by KDE.

This tool was chosen as the buildsystem for the KDE SC 4 series, and there are no plans currently to migrate away from it.

LXR indexes classes and methods used in KDE. This can be useful for finding examples of how to use a class, and finding all uses of a class while refactoring or updating API.

Review

Patch review (pre commit)

Patch review (pre commit)
Current State   People  
Get Involved   Alternative Tools  
  • Launchpad.net offers merge review/approval pre-merge [1] [2] [3]


In general KDE does not have a formal patch review policy for individual patches. Some patches do get reviewed prior to committing to svn by the relevant mailing lists. This is the case for particularly large patches or patches by new developers.

As an official policy kdereview is used to review new applications and new classes for kdelibs prior to inclusion in KDE trunk. A drawback of this system is that not all reviewers report that they have reviewed the new content. It may make sense to have a checklist for reviewers to use, eg,

  • All new classes documented [x]
  • Private classes and d-pointers used where appropriate [x]
  • Passes all krazy checks [ ]
  • No obvious security concerns [ ]
  • Designed well/maintainable [ ]
  • etc...

This was discussed to some extent here, but has not yet been refined into a techbase page.

Commit review (after commit)

Commit review (after commit)
Current State   People  
  • Action mail generic.svg kde-commits mailing list records all commits to KDE svn.
  • The CommitFilter is used to filter relevant commits based on path of the commit.
  • SVN CCMAIL: feature used to notify relevant mailing lists or individuals of specific commits.
  • SVN BUG: feature used to close bugs, and also notifies all bug subscribers of the commit.
  • SVN CCBUG: feature used to notify closed bugs of updates. Commonly used when porting fixes between branches. Also notifies all bug subscribers of the commit.

Unknown

Get Involved   Alternative Tools  
  • Unknown


The commit filter is used by several projects to forward all commits to the relevant mailing list.


Design Review

Design Review
Current State   People  

Design review takes place on

  • mailing lists
  • project wikis
  • face-to-face/BOF sessions and sprints
  • kdereview

Unknown

Get Involved   Alternative Tools  

n/a


KDE does not have an offical design review process. Some design review takes place as part of the kdereview process. It may be possible to further formalise this or encourage design documentation.

Documentation

Technical documentation

Technical documentation
Current State   People  
  • Danimo is the MediaWiki admin for techbase.kde.org.
Get Involved   Alternative Tools  

n/a


techbase.kde.org is a MediaWiki powered site used for collaborating on technical tasks such as tutorials, schedules, and project information.

API documentation

API documentation
Current State   People  
  • Doxygen is used to generate api documentation from documentation strings in code.
Get Involved   Alternative Tools  


KDE API documentation is generated nightly and hosted on http://api.kde.org. It is also possible to generate the same documentation locally for use in an IDE for example.

It is possible to create man pages and qthelp documentation from kde sources.

User documentation

User documentation
Current State   People  

Unknown

Get Involved   Alternative Tools  

n/a


User documentation is generated from module doc/ folders and hosted on http://docs.kde.org.

meinproc is a KDE tool (written by Stephen Kulow which uses libxslt to transform docbook into (bzipped) html. At runtime kio_help opens that bzipped html and displays it to the user in khelpcenter.

http://userbase.kde.org is intended to be the primary source of user documentation on the web. Content will possibly be packaged for offline use in the future.

Testing and Quality

Bug tracking

Bug tracking
Current State   People  
  • Matt Rogers and the KDE sysadmin team maintain the KDE bugzilla installation.
Get Involved   Alternative Tools  


Bug tracking in KDE currently is managed using Bugzilla 3.0. Work was recently merged on a transition to Bugzilla 3.0 from Bugzilla 2.16. There is still cleanup work going on but most features of the previous Bugzilla installation already work.

Bugzilla can be difficult to use and daunting to newbies.

Static code analysis

Static code analysis
Current State   People  
  • Krazy hosted at EnglishBreakfastNetwork (EBN).
  • Coverity is used to find possible sources of defects and suggested optimizations. Results are displayed per module as part of Dirks Dashboard builds.
Get Involved   Alternative Tools  

n/a


Additional checks are always welcome for adding to Krazy. See http://websvn.kde.org/trunk/quality/.

Build testing

Build testing
Current State   People  
Get Involved   Alternative Tools  

n/a


There is interest in more build testing for KDE especially on non-linux platforms. Improvements include some standard ctest scripts that can be used to build and submit a dashboard result for kdelibs to CDash. This would be run on a cronjob for simplicity.

Builds are planned for the following platforms:

  • Windows
  • MacOS
  • FreeBSD 6 (gcc)
  • FreeBSD 7 (gcc)
  • Solaris (S10, S11) on SPARC and amd64

Unit testing

Unit testing
Current State   People  

Unit tests may be written with the QTest framework. Tests can be run with the command 'make test'.

  • Action mail generic.svg kde-optimize mailing list coordinates optimizations in KDE.
  • Krazy and Coverity tools also include some optimization checks.

Additional contributed artwork is available on kde-look.org.

There may be a need to create tutorials on how to create artwork for kde.

Resolving licencing issues.

Resolving licencing issues.
Current State   People  
  • A Fiduicary Licence Agreement is available, which will allow KDE developers to optionally assign copyright of their contributions to KDE e.v. This would allow easier relicencing of contributors content in the event that KDE needs to move to another licence. It also allows the e.v. to more easily represent the work in the unlikely event of a court dispute involving KDE code.
  • KDE licencing policy allows commercial and non-commercial development and proprietry and non-proprietry development.
  • Projects/KDE_Relicensing Effort to relicence KDE code to use version 3 of GNU GPL and LGPL. This work is unfinished but not still being performed. Many contributors are no longer contactable.
