[Minemeld 0.9.48] - Some prototypes not available in the GUI

[camsad]

Hello team!

I hope you are doing alright !

It looks like that since the last update (0.9.48), I am no longer able to setup new nodes with the prototypes:

stdlib.localDB

OR

stdlib.aggregatorIPv4Inbound

Moreover,  a couple of my miners/nodes now have an "unknown" type.

Any idea of what could be the cause of that ?

Thanks in advance for your help.

Hi @camsad,

please could you share the output of "ls -l /opt/minemeld/prototypes/" ?

Thanks,

luigi

Hi Luigi,

ls -l /opt/minemeld/prototypes/

Hi @camsad,

which prototypes are missing from the UI?

Thanks,

luigi

Luigi,

Pretty much everything starting with stdlib

[lmori]

Could you try this command?

ls -la /opt/minemeld/prototypes/0.9.48/stdlib.yml

[camsad]

 ls -la /opt/minemeld/prototypes/0.9.48/stdlib.yml
-rw-r--r-- 1 minemeld minemeld 32243 Jun 13 06:36 /opt/minemeld/prototypes/0.9.48/stdlib.yml

diff between 0.9.46/stdlib.yml and 0.9.48/stlib.yml indicates no difference 

[lmori]

Ok, prototypes looks good.

Could you go in System > API and click on restart?

[camsad]

Done. Did not solve the issue.

[lmori]

Did you also do a hard refresh of the browser after restarting the API? Prototypes are cached both in the browser and in the API process.

If that doesn't solve, could you share your minemeld-web.log file?

[camsad]

Hi Luigi,

A stated by the minemeld-web.log file,  it was a permission issue:

Traceback (most recent call last):
  File "/opt/minemeld/engine/0.9.48.post1/local/lib/python2.7/site-packages/minemeld/flask/prototypeapi.py", line 128, in list_prototypes
    with open(os.path.join(p, plibrary), 'r') as f:
IOError: [Errno 13] Permission denied: '/opt/minemeld/prototypes/current/minemeldlocal.yml'

Then, setting "minemeld" as the owner of 

/opt/minemeld/prototypes/current/minemeldlocal.yml

solved the issue.

Thanks a lot for your help !

P.S. : Do I need minemeldlocal.yml in /opt/minemeld/prototypes/current ?

Hi @camsad,

no, you should place it in /opt/minemeld/local/prototypes. This way it won't be overwritten on upgrades.
