What’s New in Karabo 2.2.6¶

Hotfix release for MDL and cpp DeviceClient. Previously, the middlelayer devices described their schema with vectors using minSize and maxSize wrong. This is corrected here. The DeviceNode bug occurs when multiple device nodes are used in a device, giving an exception. The input channels created by DeviceClient, e.g. as happening in DOOCS, will get an instance id to not confuse connected outputchannels.

Detailed Merge-Log¶

Middlelayer Core¶

MDL: Fix current hash setting in DeviceNode !2989
MDL: Fix attribute type description in schema !2963

cpp/bound Core¶

C++: Give and id to input channels created by DeviceClient !2981

What’s New in Karabo 2.2.5¶

Hotfix release regarding cpp pipelining and GUI fixes for trashed projects. In summary, the trashing design follows now in the direction of the meta data catalogue, where one can declare a RUN quality. The trashing attribute is used in exactly the same transparent way. Trashing should be exceptional!

Save as is NOT possible anymore
GUI server can refuse old clients to enforce GUI client version
Trashing a project will not close the project
Trashing from ‘Load Dialog’ is not possible anymore
The operator is allowed to load trashed project, it might still contain valid data
Trashed projects will appear in pink in the project view and operator gets a notify dialog (2.2.4.4)

The datalogger instantiation is slowed down, to make the establish signal connection reliably and the cpp pipelining was corrected for empty detector data.

What’s New in Karabo 2.2.4.4¶

Hotfix release regarding GUI fixes for trashed projects. A loaded trashed project will appear in pink color and the operator will get a pop-up. Scene links are blindly copied if only the subproject is ‘saved as ..’ and the uuid’s are shown in tooltip fashion for projects and scenes.

In addition, the focus behavior in the Configurator was corrected.

What’s New in Karabo 2.2.4.2¶

A hotfix release run configurator due to the correct validation of readonly and reconfigurable parameters introduced in 2.2.4.

Detailed Merge-Log¶

core Devices¶

Make _RunConfigurator sources reconfigurable !2893

What’s New in Karabo 2.2.4.1¶

A hotfix release for the middlelayer api. Timestamp behavior was fixed for device node. Servers reconnect now to the timeserver. UNKNOWN state is always allowed for proxies, which is required since the state is set to UNKNOWN if the underlying device is gone.

Detailed Merge-Log¶

Middlelayer core¶

FIX bound mdl pipeline integration test !2883
MDL: Always allow State UNKNOWN for state property in descriptor !2882
MDL: Fix device node timestamp handling !2878
MDL: Reconnect device server to timeServer !2877
MDL: Provide possiblity to explicitly close outputchannel !2874

Graphical user interface¶

GUI: Protect trendlines against -np.inf and np.inf !2870

What’s New in Karabo 2.2.4¶

The most relevant improvements and fixes are:

getServers() and getDevices() account for visibility (!2761, !2774)
Pretty Print output (!2766)
Add getSchema and getConfiguration (!2707, !2720)

MDL: Harmonize device interface with C++/bound - slotClearLock, lastCommand, process id, input channel EndOfStream handler (!2799, !2744 !2845, !2742)
MDL: Pipelines automatically reconnect (!2855, !2867)
MDL: Full trainID integration (!2694)
C++, bound: Speed up NDArray (de-) serialization for pipelines processing (!2725, !2783, !2775)
C++, bound: Fix runtime attribute setting for reconfigurable parameters (!2717, !2726)
C++, bound: Do not ignore empty keys in Hash (!2706)
C++, bound: Hash printing suppresses content of long vectors/NDArrays (!2698, !2739)
Add State.PROCESSING to Karabo (!2806)
Add binning information to ImageData (!2691)
Bound: Fix setting of timestamp (!2722)

GUI: Fix that sometimes project data was stored in wrong domain (!2757)
Flickering alarms do not block GUI anymore (!2772)
GUI: Implement macro code editor with line numbers and highlight (!2779)
GUI: Pop-up for properties in the configurator can be freezed to allow copy/paste from it (!2850)
GUI: Clean-up icons, add new ones (!2751, !2750,!2749, !2718)
GUI: Easier precision placement of scene items (!2745, !2723)
GUI: Display YUV images (!2661)

Empty strings are now valid keys of a Hash.

Before, a completely empty path (aHash.set(“”, something)) let to a crash and empty keys as part of a path with sub-keys were simply ignored. That means that aHash.set(“a..b.”, something) had the same effect as aHash.set(“a.b”, something), i.e. a path with the two sub-keys a and b, whereas in Karabo 2.2.4 the path of the former actually differs and has four sub-keys of which two are empty keys.

What’s New in Karabo 2.2¶

C++ and Bound Python¶

Standalone DeviceClient¶

The constructors to create a standalone DeviceClient do not take anymore arguments about the broker connection. They always use the default behaviour.

Instead, one can now specify the instanceId of the DeviceClient object instead of getting a default one generated: DeviceClient(instanceId). In fact, that is the recommended way since otherwise a program that crashes after creating a standalone DeviceClient may leave remnants in the system, even if restarted.

These remnants are useless signal subscriptions since the restarted program has a new instanceId. They can potentially slow down the broker and every recipient of the emitted signals. If restarted with the same id as before (as usually is done with devices and servers), these remnants are cleaned.
