Scripts and hacks
Things we do unrelated to the code in git/gerrit.

working with UUIDs
Base 36 has code to convert to/from Flow's alphadecimal representation of UUIDs in URLs e.g.  . Note JavaScript integers have insufficient precision, e.g.

There are online base36 converters, e.g. this one with ads.

mysql
We store 88-bit UUIDs in  columns, so they appear as garbled strings such as: �#�����o~p

In mysql, use  and , e.g.:

There is no (?) mysql function to convert to/from Flow's alphadecimal representation.

Determining database, gaining access
The configuration of Flow's cross-wiki external database can be opaque.

ssh into MediaWiki server (e.g. deployment-bastion for the Beta cluster or terbium for production), then $ mwscript eval.php --wiki=enwiki var_dump( Flow\Container::get( 'db.factory' )->getDB( DB_MASTER ) ); this will give you mServer, mDBname, mUser, mPassword to connect from the mysql command line.

E.g. from a labs instance to access the beta cluster, $ mysql -u mUser -p --host=mServer mDBname (enter mPassword)

Clearing cache
Flow caches topic data which can prevent changes and fixes showing up.

If you're using memcached sudo restart memcached

If you're using redis (the default in MediaWiki-Vagrant echo flushdb | redis-cli

However, we can't do this in production. If code you introduce needs to clear the cache, instead your patch should bump. But note in production the one Flow DB is accessed by wikis running different versions of the Flow code...

ee-flow
spage has a cron job that updates Flow and Echo, see the /etc/motd

Don't run git as root. We have git configured for group sharing, so it shouldn't be necessary. If you get permission errors, run sudo chmod -R g+w. && sudo chgrp -R project-editor-engagement.

flow-tests
flow-tests runs Labs-vagrant. There's no labs-vagrant git-update, so

to update other extensions $ cd /vagrant/mediawiki && sudo su vagrant $ git pull --ff-only $ cd extensions $ for i in */ do cd $i git checkout master git pull --ff-only cd /vagrant/mediawiki/extensions done
