ready for the views creation

@Banyek did GRANT this wiki into the labsdb user role grants? If not, the views will fail to be created

I did the grant as

 set session sql_log_bin=0; create database shnwiki_p;
Query OK, 0 rows affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> set session sql_log_bin=0; GRANT SELECT, SHOW VIEW ON `shnwiki\_p`.* TO 'labsdbuser';
Query OK, 0 rows affected (0.00 sec)

Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]>

@Bstorm you can work with this

Ping? Other similar tasks (T205713) are closed, is this one waiting on anything?

Mentioned in SAL (#wikimedia-operations) [2018-11-28T16:50:24Z] <gtirloni> T206916 created shnwiki views/index in labsdb replicas

On my side, sql shnwiki on labs runs okay. Running @Pathoschild's command linked above does fail though.

@MarcoAurelio most likely the wikis is available but not on the meta_p- I am unsure if adding it to meta_p is a process that runs regularly from time to time (so it is only a question of waiting) or it is done automatically by a script, or handled manually. Ping @GTirloni in case he can research it as that seems missing according to user reports.

The step of running our maintain-meta_p script had not been done yet apparently. After running sudo /usr/local/sbin/maintain-meta_p --databases shnwiki --debug on each of the Wiki Replica backend servers:

$ sql meta
( [meta_p]> SELECT * FROM WHERE dbname = 'shnwiki' OR url = ''\G
*************************** 1. row ***************************
          dbname: shnwiki
            lang: shn
            name: Wikipedia
          family: wikipedia

I only ran that command on the first replica server (labsdb1009), that must be it. Did it work without errors on all 3 servers?

Note: we should maybe take a look at recently created wikis at Wiki-Setup (Create) and check if they're also added to the table. Or compare its contents with public.dblist @ operations/mediawiki-config and find if any public wiki which is at public.dblist is missing on the table. I'm sure you'll find a better way to do it :) Thanks.
