@phuedx what am I missing? I've checked and it seems that if MFUseWikibaseDescription is false we don't add the property to the parser output.

Regarding impl, this is what I see:

• Move header html from SkinMinervaBeta to [[ https://github.com/wikimedia/mediawiki-extensions-MobileFrontend/blob/235fbcf537b3d1648d05b9638b29d8f555fad066/includes/skins/SkinMinerva.php#L613 | SkinMinerva ]]
• Remove references to isBeta when adding the property to the parser output
• Update readme to remove references to beta regarding the config variable

Is there anything else TODO? I'm going to tentatively add it to the description.

I've also added Change wm config to disable the feature by default and enable on first rollout wikis.

Do we want to have this feature disabled by default on MobileFrontend proper? Or enabled by default in MF, disabled for all wm wikis, and enable per wiki as we rollout? (with the intention of removing the WM config once the adoption is spread)

Disabled by default.

While the feature is enabled, we're adding metadata to the parser output. While the feature is disabled, we're not using the metadata but it might still be there, until the page is edited again. We need to be clear about whether we're going to actively remove the metadata from the parser output.

We're going to use this task for preparing the beta feature to roll out to stable.

Please create followup tasks blocked by this one to enable the feature on specific wikis (ping @JKatzWMF @dr0ptp4kt @Moushira @Lydia_Pintscher)

@JKatzWMF @Moushira @Lydia_Pintscher, so would this be the proposed rollout?

1. Roll to Spanish, Portuguese, and Polish for a week
2. Then roll to the rest. (Also, what is the rest?)

To be clear, this task (let's call it (0)) here is the part that makes it possible to do (1) and (2). That is to say we'd probably need a week or two between (0) task being merged & deployed and (1) happening.

@dr0ptp4kt @Jhernandez Sounds good to me! Thanks.

Regarding #2 is it only mdot Wikipedias?

I've created the following on the hunch we're talking mdot Wikipedias only right now.

T135429: Deploy Wikidata descriptions to Catalan and Polish mobile web Wikipedias stable
T135433: Deploy Wikidata descriptions to all mobile web Wikipedias

I'm moving this to sprint 74, in recognition of slightly higher Hovercards bugfixes load than expected.

It seems like what we have here is a conflict of use cases. According to the official guidelines, the purpose of the description is to "disambiguate items with the same or similar labels," which is subtly but crucially different from our use case of "a one-line summary of the subject."

This seems to be an even bigger concern than forcing mobile web Wikipedias to use Wikidata descriptions.

@jhobs can you also do the last bullet point?

Of course, just ran out of time last week and wanted to get it in code review. If I'm not mistaken though, won't we need to SWAT deploy the labs patch first? If not, I may be misunderstanding the the last bullet point (I assume it means "screenshot cached pages after the change has been implemented."

You can test how your patch affects the cached pages by following these steps:

1. ./dev-scripts/cachedpage.sh 6d588b23ddab1a2cb1514d97018a8213063153ad San_Francisco <- The command fetches the San Francisco article for the commit 6d588b23ddab1a2cb1514d97018a8213063153ad which is before your change.
2. The above command creates a file called /tmp/cached.html which you can access using the browser. While accessing the file, make sure your patch is active.

The second step above does not occur when I run the command. The script executes "successfully" and says the file has been generated, but no such file exists.

@jhobs /tmp/cached.html is relative to the MF extension directory, not the system dir. Mybad.

Yeah, I understood that. The tmp folder in my extension directory is empty.

Weird! This worked perfectly for me.

@jhobs I think your config file is ready to be SWAT deployed.

@bmansurov thanks. I'll talk with you guys at standup to see when a good time to schedule it is.

Can someone else upload the cached page screenshot? I was finally able to get the dev script working with the help of Baha, but I can't view the page within Mediawiki for some reason (maybe I need to wipe vagrant...).

It looks like the SWAT deploy is going to happen on Tuesday 2016-06-21. With that in mind, I'm moving this back to RfS since it's been verified.

Check that, it's happening tonight. Thanks @dr0ptp4kt!

Test how cached pages appear and post a screenshot on the card.

👍

Okay, @bmansurov and @jhobs and I spoke this afternoon. As noted in the patch:

* Note: A follow-up deployment will happen on Monday to disable
*       this by default on production. It is not included in
*       this patch in order to minimize the time in prod-beta
*       without wikibase descriptions.

Some additional code on top of the existing MASTER is also needed to add logic to ensure beta will generally retain Wikidata descriptions.

^ Heads up @Lydia_Pintscher there may be a brief period next week on beta mobile web Wikipedias where you wouldn't see Wikidata descriptions, but work will be in flight to keep that period short.

@dr0ptp4kt do we have follow-up tasks for:

A follow-up deployment will happen on Monday to disable this by default on production

and

Some additional code on top of the existing MASTER is also needed to add logic to ensure beta will generally retain Wikidata descriptions.

?

@Jhernandez, I'll file the Task for the SWAT.

@jhobs is going to fix the conditional logic via this task to make it complete.
