Lost device attributes when restart Server
|

---|---|
Hello, I have created a Tango Device Server with 4 devices that have dynamic attributes. I want to restart all devices in the device server. According to the doc, that is the function of DevRestartServer. But when I call: Only my first device gets its attributes back.The 3 other devices restart with no attributes. Did I miss something or is there an issue in restart_server function ? |

Hi Marc, Could you please give us more details on the versions you are using? How did you install Tango? What version of the Tango C++ library are you using? What version of Pogo are you using? In which part of the code are you creating the dynamic attributes? If possible, could you please send us a simple piece of code reproducing the problem? I tried to reproduce the issue with Tango 9.2.5a and POGO 9.6.3 with a simple case (creating the dynamic attributes in add_dynamic_attributes() method) but I did not see the issues you were reporting here. Kind regards, Reynald

Hello, I have built the libraries from source code with theses versions : Zeromq-4.0.5, omniORB-4.2.1-2, tango-9.2.2 For Tango, i used the following option : configure –prefix=/opt/tango –disable-jpegmmx Pogo is in version 9.2.4. To create dynamic attribute, i used the example : how-add-dynamic-attributes-device-class I am trying an alternative: to add attributes dynamically after device creation. It works. But I have a crash when I: - restart server - addAttribute to the devices - device->setState(Tango::RUNNING) : problem of event subscription at this point So I will update to Tango 9.2.5a and generate again my DynAttr class. If I still have the issue, I will send you the piece of code. |

The loss of my attributes after restarting the server was due to spaces in attribute names. I have tested also with spaces in device name. My attributes are also lost. I have noted that pogo remove spaces for attributes. Is it forbidden ? I will add some checkings for names in my device/attribute editor. |

As far as I know, spaces are indeed forbidden in attribute names and device names. This is why Pogo is removing the spaces.
