Remote Debugging Status

Overview on the ongoing work to enable remote debugging with GammaRay.

Core

• split the ToolFactory for core/ui so we can also split plugins
• use ToolModel for the plugin info dialog, so we see the server state rather than the client one
• remote selection model sometimes "oscillates" [DONE]
• add deferred QHeaderView configuration also for sort order (lost on column count reset), and possibly other QHeaderView settings as well
• compress dataChanged() signals in RemoteModel
• QIcon serialization across processes does not work unless QRC file is available in both

Server

• automatically pick a different port if the default one is already in use

Client

• properly handle connection errors [DONE]

Launcher

• add support for SSH remote launch
• adjust launch and attach actions to use out-of-process mode by default

Tools

• split core and ui parts
• turn tools with QtWidget dependency into plugins (same for QtGui even?)

Action Inspector

• core/ui split [DONE]
• triggering actions does not yet work remotely [DONE]
• Qt patches https://codereview.qt-project.org/#change,53097 / https://codereview.qt-project.org/#change,55367 are needed to properly view the action model remotely (integrated for Qt 5.1.0 and Qt 4.8.5)

Connections

• core/ui split [DONE]
• was using a proxy detacher optimization before, still needed considering the remote model (un)monitoring feature?

Fonts

• font preview needs to be rendered on the server side
• basic core/ui split [DONE]
• triggers a crash on QCoreApplication [FIXED]

Graphics Scene

• needs to be turned into a plugin [DONE]
• basic core/ui split [DONE]
• scene preview and overlays don't work remotely
• initial scene selection fails
• glitches in the scene model amplified by remoting

KJobs

• core/ui split [DONE]
• UI does not depend on KJob and thus could be built even if KJob is not available (e.g. with Qt5)

Locales

• core/ui split [DONE]

Messages

• core/ui split [DONE]
• qFatal handler still depends on QtWidgets [DONE]

Meta Objects

• core/ui split [DONE]
• initial tree expansion still assumes immediately populated model

Meta Types

• core/ui split [DONE]

Mimetypes

• core/ui split [DONE]

Models

• core/ui split [DONE]
• QModelIndex details shown in the client are not the ones from the server
• for viewing content of proxy models that overwrite data() https://codereview.qt-project.org/#change,53097 is needed

Objects

• core/ui split [DONE]

Object Visualization

• port me!

Resources

• core/ui split [DONE]
• first column doesn't show content remotely [DONE]
• content preview is not yet working remotely (might need on-demand role loading in RemoteModel)
• tree view and splitter setup fails due to lazy model population
• triggers crash in Qt due to QFileIconProvider when used inside a QCoreApplication.

Script Engines

• probably unportable, hide in out-of-process mode [DONE]

Selection Models

• core/ui split [DONE]
• selection content view does not work remotely yet [DONE]

Standard Paths

• core/ui split [DONE]

State Machines

• port me! [IN REVIEW: https://github.com/KDAB/GammaRay/pull/55]

Style

• needs to be turned into a plugin [DONE]
• core/ui split [DONE]
• performance issue: all rendered primitives seem to be transferred initially rather than on demand
• some states are stuck on "loading..."
• view properties (height, width, zoom) are not working remotely
• icons are not properly transferred [DONE]
• initial style selection fails
• crashes when selecting a different style remotely before showing the style locally/in-probe

Text Codecs

• core/ui split [DONE]
• move into plugin [DONE]
• selected codecs model resets on text change, causing annoying flickering when used remotely [DONE]

Text Documents

• core/ui split [DONE]
• content preview does not work remotely
• block bounding boxes are not shown remotely

Timers

• core/ui split [DONE]
• periodic view update needs to be moved to the model

Web Inspector

• WebKit 1 inspection not available remotely - show information message [DONE]
• WebKit 2 inspection:
  • enable developer mode automatically
  • use hostname and port from the GammaRay connection
  • environment variable apparently not set early enough

Widgets

• needs to be turned into a plugin [DONE]
• basic core/ui split [DONE]
• "Save As" actions need to send data to the client, to be written into a file there
• paint analyzer needs to be split in client and server part
• widget preview does not yet work remotely [DONE]
• initial selection happens too early for anything being present for selection
