Components

The bugzilla product kwin has several Components. Here a short overview is peresented.

General

Component general for untriaged bugs or not fitting anywhere else.

Core

Core components include everything that is part of KWin core.

Core

Bugs directly in the core of KWin. E.g. stacking order related

Tabbox

Everything related to Alt+Tab except effects

Tiling

Everything related to window tiling.

Scripting

Everything related to KWin's JavaScript itnerfaces

Client Grouping

Everything related to client grouping aka window tabbing. This is the crashers in core, but not the implementation in decorations.

Compatability

Activities

Everything related to Activities

Rules

Everything related to KWin's window specific rules handling

Multi Screen

Multi screen related bugs

Multihead

As before everything to multi head (two+ X servers)

XRandR

Bugs related to XRandR (modern). General multiscreen issues should be put into this component.

Xinerama

Anything to Xinerama/Twinview (legacy).

Compositor

Compositing related bugs in the core (not effects).

Compositing

General bugs either in the effects library or it's implementation in core and scene.

Scene-OpenGL

OpenGL related compositor bugs.

Scene-XRender

Xrender related compositor bugs.

Colorcorrection

Bugs related to the color correction integration inside the Scene-OpenGL

Decorations

KDecoration

Bugs in the decoration libraries (KDecoration and KCommonDecoration) plus bugs in the bridge.

Decorations

Bugs in various decorations shipped with KWin (e.g. Plastik), but not Oxygen (has own component and product) and not Aurorae.

Aurorae

Bugs in the Aurorae Theme Engine

Appmenu

Bugs related to app-menu integration inside window decorations

Effects

Effects-Various

Bugs in any effects not matching into the more specialized components.

Effects-Tabbox

Bugs in any tabbox related effects (boxswitch, coverswitch, flipswitch).

Effects-Window-Management

Bugs in effects for window management (e.g. PresentWindows and desktop Grid).

Handling priority

For the purpose of making handling of (not so small number of) KWin bugreports simpler, each bugreport should have a priority assigned, making it possible to sort the list of bugreports and see what bugreports should be handled first. For consistent setting of priorities, these rules should be followed:

Priorities

There are 5 priorities, VHI (highest), HI, NOR, LO, VLO:

VHI - urgent, should be handled as soon as possible. Examples: Broken trunk, stable branch often crashing for many people, basic often-used feature not working properly, etc.
HI - important, should be ideally fixed for the next release (meaning minor release, i.e. x.y.0). Examples: A crash that may happen for many people but is not critical, a basic but non-critical feature not working properly, very good idea for a new feature, etc.
NOR - the default, no priority has been assigned yet (new bugreports get this priority and should get other priority assigned)
LO - not important enough to be in the next release, low priority for when somebody will feel like fixing it. Examples: Relatively rare crash, not-often-used feature not working, feature request without important benefits, etc.
VLO - minor issues, too specific or questionable (but still reasonable enough, complete nonsense or "nobody will ever do that" should be closed with WONTFIX).

A short simple way of explaining the priorities is "VHI ASAP, HI reasonably soon, LO somewhen, VLO who knows when".

Guidelines

It is important to note that these rules are just guidelines and do not need to be strictly followed when it makes sense (for example, a minor crash that should be however simple to fix can get HI in order to be checked before next release). Specifically, the examples given are just examples and the description of the priority should be used. The main purpose of these rules is to help with handling many bugreports, not to have rules for the sake of having rules. It is not a big problem if at the time of a KDE release there are tens of HI bugreports.

Wishes should use the same priorities like normal bugreports.

Flags

Driver Specific

For each of the drivers a flag exists. This should be used to indicate that a given bug is specific for a driver. If the flag is set to "+" it means that the bug is specific to a given driver. All those flags are not requestable.

NVIDIA

Bug is specific to the proprieatary NVIDIA driver.

Catalyst/fglrx

Bug is specific to the proprietary ATI/AMD driver.

Intel

Bug is specific to the Intel driver.

r300g

Bug is specific to the Mesa driver for ATI r300 generation (Gallium driver).

r600g

Bug is specific to the Mesa driver for ATI r600 generation (gallium driver).

nouveau

Bug is specific to the Mesa driver for NVIDIA.

Gallium3D

Bug is specific to any Gallium3D driver.

Mesa

Bug is specific to any Mesa driver.

Workflow Related Flags

Reproducable-4.8

A requestable flag to ask whether a user is still able to reproduce the report with KWin 4.8. If yes it should be set to "+", if not it should be set to "-".

Reproducable-4.9

Like Reproducable-4.9 for the next version.

Triaged

A requestable flag to indicate whether the bug report has been triaged (put into correct category). "?" means unknown, "+" means is in correct component, "-" it is in the wrong component.

Decision Required

A flag to be set by a developer to ask another developer for a decision. The flag is specifically requestable.

Answer Required

A specifically requestable flag to ask the user for an answer (e.g. config options, better backtrace, etc.). User should set it to "+" when it has been set. As the user might be asked several times for answers the flag is multiplicable.

Review Request

Whether a Review Request has been created for the bug report.
