= Mailing list and IRC =

The central places to get help and to meet the crowd are
 * 1) labs-l, the mailing list. This is an excellent place for your questions. And subscribe to it too!
 * 2) #wikimedia-labs connect, the IRC channel on the freenode network (more information).

= Table of features and tools' dependencies needed for current tools =

At the end of 2012, a list of features has been started. Feel free to add things! In the first part, we are collecting indispensable technical features Labs needs to offer what the toolserver has to offer now. Below, there is a list of features that are nice to have.

Wikimedia Labs/Toolserver features wanted

'''In addition, we are collecting technical details (like software and data dependencies) about tools on the toolserver to make Tool Labs fit for the existing tools. We need all tool developers' help to complete that list.''' Please edit it here:

Do I have to migrate my software to Tool Labs?
You are all volunteers. We know that you are putting your free time into the development of tools to improve Wikimedia projects. We know that we are asking extra work by asking you to migrate your tools. Unfortunately, at some point in 2014, WMDE will discontinue the toolserver so that staying is no option. So we really encourage you to move over to Tool Labs.

When can I migrate my software to Labs?
Now. For many tools, database replication is a crucial prerequisite that is available now. Cluster s7 (with CentralAuth) is still missing, but upcoming in June 2013.

What do I have to think of when finishing migration?

 * Please clean up on the toolserver: Once your tool is running inside Labs/Tool Labs, please delete it from the toolserver and announce to the toolserver admins that your account can be deleted.

Where's the bug tracker?

 * WMF uses using Bugzilla. Please use it for your issues!
 * There are the following categories in Bugzilla:
 * product: "Wikimedia Labs"
 * component "bots" - for bot-related issues
 * component "General" - Issues surrounding set up of labs projects.
 * component "deployment-prep" - Bugs relating to the configuration/management of the WMF deployment-prep project at http://beta.wmflabs.org. More info: wikitech:Nova Resource:Deployment-prep.
 * component "Infrastructure" - Bugs related to Wikimedia Labs infrastructure and not a specific Labs project.
 * component "webtools" - issues related to webtools
 * component "wikistats" - http://wikistats.wmflabs.org/
 * If former Jira users need help / introductions, please don't hesitate to ask your questions on labs-l or on IRC (links above). Inform us about wishes for workshops! We are considering to offer workshops about software you are/will be working with in Labs that you didn't have on the toolserver. Tell us what you need!

Where is documentation?

 * wikitech:Help:Getting Started
 * Labs Glossary
 * Magnus Manske's experience when migrating a tool

What about file permissions? Who can see my code?
There are projects where users have root, so that all users in the project have full access to the whole project. This setup is not mandatory though: Tools can also use tool user IDs to control file permissions. On the tools project (which will be where toolserver tools migrate), you have full control over access permissions of your code and data. By default, only the tool maintainers have access (all the maintainers of a tool are in the tool's group).

Do stewards have a specific project on WMF Labs?
There is no plan to have distinct projects for different tool makers; but the tools are separated from each other. There is nothing that prevents you from sharing the maintenance of some tools between different stewards (in fact, it is recommended that you do so to ensure that there is always someone able to keep them up at need).

Do I explicitly have to specify the license of my tools?
Yes. If you think "this is just a draft, nothing ready" and you do not put a license into your code it's non-free software contradicting the idea of Tool Labs. So please add a license in the beginning!

How do I access the database replicas?
mysql --defaults-file=~/replica.my.cnf -h enwiki.labsdb # <- for English WP mysql --defaults-file=~/replica.my.cnf -h dewiki.labsdb # <- for German language WP mysql --defaults-file=~/replica.my.cnf -h wikidatawiki.labsdb # <- for Wikidata mysql --defaults-file=~/replica.my.cnf -h commonswiki.labsdb # <- for Commons mysql -h commonswiki.labsdb # <- for Commons
 * In your home directory you find your credentials for mariadb (in the file replica.my.cnf). You need to specify this file and the server you want to connect to. Some examples:
 * Alternatively you can rename the credentials file from replica.my.cnf to .my.cnf and just run

= How can chapters, communities and developers support the process =

Now / Phase of preparations

 * You are running software on the toolserver? Please document what you need for it to work (link above)! Focus on functionalities rather than exact details, e.g. software versions.
 * Please talk to us if you are ready to become an early adopter to try Labs, e.g. once the database replication is up and running.

Know how and documentation

 * You are planning migration or did already accomplish it? Please help us to improve and add documentation. If you miss documentation, poke us. If you found out undocumented processes on your own tell us about them or write them down. If you don't know where to put documentation, don't hesitate to ask!
 * Would you like to give a talk or a workshop on a topic related to the Toolserver -> Labs transition at a Hackathon or online? Don't hesitate to propose it to us!

Hands-on support for others

 * You have migrated your own project successfully and feel like supporting somebody else? You are able to adapt software that needs modifications? Your help would be greatly appreciated! Please talk to us!

Financial support
Are you a chapter or some other project with funding, using the toolserver?
 * Please consider donating for the toolserver so it can run until we have got an alternative ready.
 * If you have paid developers in your projects, please consider paying them to migrate your project from the toolserver to Labs. You could even have them offer support to another / a related volunteer project if this is fine with the volunteers.
