Dashboard contents are not shown in Fedora 23

[lcorreia]

No error shown in log. In firebug I can see the following:

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help http://xhr.spec.whatwg.org/ jquery.min.js:5:0
not well-formed :1:80
TypeError: data.memory is undefined jquery.min.js:636:9

It is worth saying that this error was revealed when installing Ginger via RPM.

[samhenri]

Does it happens on all browsers (including Windows browsers when you access the server remotely)? The XMLHttpRequest message is just a warning and not part of the problem, it is due to jquery implementation.
I haven't touched a bit of the dashboard js scripts, I just tweaked a bit from the line-charts JS and the old kimchi.hosts.js that had the scripts for all the components in Host tab. Last time I checked it was fine on Fedora 22 but I never installed by RPM.
I believe this problem might be related to dependencies not being installed. I had the same problem in the latest CentOs build. Can you check on Chrome and confirm if you have the same errors on the developer console?
It would also give a hint if in the Networks tab from Google Inspector it shows the "stats" XHR request and it contents.
I think data.memory key should come from this json so if it's empty, undefined or null, it must be a problem.

I can assert that this bug is happening in the RPM install of wok/ginger/gingerbase in F23. I don't believe this is a F23 only issue though.

This is the result when loading WoK for the first time in Chrome running in incognito (private) mode:

To be completely fair this is an 'old' error of the old UI that happens quite often even when things are working. Thus I don't know if this is the root cause of this specific bug (although it should be looked at when possible).

This is the error that happens when trying to load the Dashboard tab:

I've expanded the error in the console to show you more details:

From this screenshot we can see that the error is happening because data['memory'] is undefined, as said in the first comment of this issue. Again, this was discovered running in Chrome in private mode, so cache problems are somewhat discarded too.

If you have a Fedora 22 machine it is possible to create the RPM packages and install them in your own environment to see the error occurring:

• build wok, gingerbase and ginger
• execute $sudo make rpm in Wok root, Gingerbase root and Ginger root. The RPM will be generated in the rpm/RPMs/noarch subdir
• install each generated RPM using rpm or even yum/dnf
• run wokd service: $ sudo systemctl start wokd.service
• if everything goes smooth, WoK should be running in localhost:8000.

Let me know if you have issues creating the RPMs. @lcorreia and myself are actively to make the packaging works due to the WoK/Gingerbase separation from Kimchi and if a new problem is detected we'll try to fix them ASAP.

Hi @danielhb! Hi @samhenri!

Recently the API was changed to return multiple values for memory.
It is worth to verify the backend too.
@chandrureddy, could you, please, take a look on it?

[danielhb]

This is the current API:

[danielhb@arthas gingerbase]$ curl -u root -H "Content-Type: application/json" -H "Accept: application/json" -k "https://localhost:8001/plugins/gingerbase/host" -X GET
Enter host password for user 'root':
{
  "os_distro":"Fedora",
  "cpus":{
    "offline":0,
    "online":4
  },
  "cpu_model":"Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz",
  "os_version":"22",
  "host":"arthas.ltc.br.ibm.com",
  "os_codename":"Twenty Two",
  "architecture":"x86_64",
  "memory":{
    "offline":0,
    "online":8059600896
  }
}[danielhb@arthas gingerbase]$ 

At first glance it doesn't look that data['memory'] is undefined

[potula-chandra]

@danielhb, First errors due tot he fact that we split the functionality of the Host into Dashboard and Updates. I guess we also need to split the help html same. Probably I will work on the help split part.

@sureshab, Could you please quickly help in to solving the memory attribute issue ?

[danielhb]

Update: in F23 the gingerbase/host API returns empty:

[danielhb@localhost ~]$ curl -u root -H "Content-Type: application/json" -H "Accept: application/json" -k "https://localhost:8001/plugins/gingerbase/host" -X GET
Enter host password for user 'root':

{}

I consider this a backend bug, not an UI one. I'll reassign it to myself for the time being to free up @samhenri queue. Let me know if someone else is willing to fix this

@chandrureddy ,

"First errors due tot he fact that we split the functionality of the Host into Dashboard and Updates. I guess we also need to split the help html same. Probably I will work on the help split part."

Okay! Feel free to create a new issue to report this bug if you like.

[potula-chandra]

Yep Sure.

@danielhb
Please feel free to reassign this issue to me. I can take a look at back end code.

[danielhb]

@sureshab , I just went trigger happy and fixed this bug. The fix is available in the ML.

Thanks
