What’s New in Karabo 1.4¶
This chapter explains the new features in Karabo 1.4.
New Features¶
Device Ids with Slashes¶
Since release 1.4.0, device ids are allowed to contain slashes (‘/’) to support the European XFEL naming convention.
To allow that, the file names used for data logging had to be changed in a non-backward
compatible way. If an existing installation is upgraded from 1.3.X to 1.4.0 or beyond,
manual intervention is needed to keep the logged data history accessible. For that purpose
a script is provided in $KARABO/bin: convertKaraboHistoryFrom13X.sh
.
It has to be run once on the host of the data logger server(s). Consult the --help
option of the script for further details.
Bug Fixes¶
1.4.2¶
- Several fixes to improve the stability of Karabo, especially cases where the broker topic continuously filled with unacknowledged messages until the topic was full and Karabo became not responsive.
- Fixes in reading back device history. It is recommended to rebuild the index
files in the
karaboHistory
directory of the data logger server(s) using theidxbuild
executable (in$KARABO/bin
). Avoid doing that while the system is running.
