BUG reports




Install notes 

...

Problem with php composer.phar install ....   cannot access DB over had to reconfigure mysql access method via localhost to older way (mysql_native_password) ... IMHO   ubuntu 16.04 specific, NOT related to MEICAN ... 

configure Apache ...   OK 

Initial configuration notes

No certificates yet ...  is that a problem for function testing? 

Configure CS under "circuits" ....   point it to "lab" domain aggregator from table above

Operation notes and first try

Logged in as master ....  master is in root group and root is the system group ...  it seems that one need user with DOMAIN role to be abble to work with topologies.... 

Created user "admin" ...  and now ...  need to add "Roles for Domains" 

Problem and IMHO a  BUG: The dialogue window for adding the role requires to specify DOMAIN ...   There is no DOMAIN created ye!!  One must have a role for domains to be able to create domain, but DOMAIN needs to be specified to add role...  Chicken and egg problem (smile) →  DEADLOCK   
(I did not hit this before in older version)
Work around: I injected the DOMAIN to mysql manually from the root console of the server and it works, domain is now available in meican to choose when adding role ... TODO: Report possible BUG 

Role added OK ,  user "admin" now can manage topology

Domain already there in topology ....   (because.... previous work around)

Dyscovery: use the topology service provided by lab1 uPA to discover the topology ... place it under the "lab" domain created before .... 
topology discovered ....  apply all ports found ... 
OBSERVATION: This automatically created new domain called lab1.nsi.new.lab (fetched network id of the uPA). I do not want this. I need the topology of this uPA placed under the lab domain. Lets look at this later ...  just ignore the created domain for now ....  lets check ports and edit the domain ....

What is the semantic of Providers and Networks in MEICAN?? investigate later .... 

Problem and IMHO a  BUG: Cannot open the Ports section. Getting a error message: Error processing your request. Sorry. :(  Debugging console provides log message: "PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'meican.meican_device' doesn't exist in /home/taas/meican/vendor/yiisoft/yii2/db/Command.php:900" . 
It looks like that meican is trying to query unexciting table in DB ... BUG?  There was a Device section in topologies before in previous version of meican. Could this be related?    Anyway ... cannot manage ports ....     TODO: Report possible BUG 

Try to reserve a circuit:   Looks ports are there...   I can choose them in the reservation form. Filling the form OK ...   Reserving ... 

Reserve state screen occurred:  looks it hangs on something  BUG? ....   lets check aggregator ....   NO request arrived .... does meican send anything at all?   

Found this in logs:
