[ome-devel] Python API - Server version check

[Sebastien Besson]

Hi Luca,

sorry for the delay. To implement a simple dependency check, your code changes make sense and I don't see anything wrong with your implementation.
Obviously, modifying the version target creates a very tight coupling between the omero version and the biobank version, but this may be exactly part of the design you want to achieve.

I am away for two weeks but I will definitely try out omero.biobank once back from vacation. I will let you know if I have some extra comment by then.
Note also that providing ways to define dependencies between server and components is something we want to explore in the upcoming months.

Cheers,
Sebastien

Thanks Ola!
I used the omero_version variable and the configService to perform a check between client and server versions (as you can see in the attached python example) and it worked fine.
I also added a property in the components/antlib/resources/global.xml file like this

<!--
   OMERO.biobank properties
-->
<property name="biobank.version" value="0.6-beta"/>

and updated the build.xml file like this

    <target name="version">

        <gitdescribe select="\2\3\5\6">
        </gitdescribe>
        <echo>${version.describe}-ice${versions.ice_lib}-biobank${biobank.version}</echo>
    </target>

in order to apply the biobank tag we needed.

The results is

luca at tensa-zangetsu:/opt/omero_4.4.8$ ./build.py version
Buildfile: /opt/omero_4.4.8/build.xml

version:
4.4.8-dirty-ice34-biobank0.6-beta

BUILD SUCCESSFUL
Total time: 0 seconds

Are these the right files that I need to update or is it better to make these changes somewhere else?

Thanks

Luca

Hi Luca

There is a python function in https://github.com/openmicroscopy/openmicroscopy/blob/dev_4_4/components/tools/OmeroWeb/omeroweb/webadmin/webadmin_utils.py#L12

you just need to call it during the login process

from omeroweb.webadmin.webadmin_utils import upgradeCheck
upgradeCheck()


Thanks
Ola

Hi,
is there a way to perform a version check between the Python API and an OMERO server?
We need some kind of automatic mechanism that will throw an exception if the version of the server and the version of the compiled API are not the same (i.e. using an OMERO 4.4.8 Python API against a 4.3 OMERO server).
Our idea is to add a "biobank" tag to perform a check which can guarantee that the API we are using was compiled against the same ICE version and the same OMERO.biobank models used to compile the server.

Thanks,

Luca
