Putting this in the backlog since it's waiting on Eran (who's on vacation).

@Niharika: What's the status on this now?

It's in progress. I added the script to crontab and did a test run which ran into an error with iThenticate being down or hitting the query limit. Trace here: P4438
I'm going to try and add error handling to the script. Pinged Eran about it, yet to hear back.
For now, the script is running fine and we have data: https://tools.wmflabs.org/plagiabot/fr?filter=all
Community Tech Bot is auto reviewing all of the records because right now it only checks against enwiki. I'll close this task after fixing this.

I've gone over the code and it seems alright, it's not explicitly querying against enwiki API but it's still somehow checking for dead pages against enwiki only. The API querying code seems fine because the same part is used for getting editor and editor contributions etc. Somehow just this part is broken.

Maybe @Samwilson or @MusikAnimal can take a look. :)

Looking into it. I did notice red links won't show for user/user talk. When you query for User/User talk pages on another wiki it will work (example), automatically normalizing to that wiki's namespace title, but in the code we're comparing the hard-coded "User" and "User talk" strings. I think we can somehow do this without creating a hash of each wiki's user / user talk namespace titles.

Still looking into this... a few other things: I had to update the production CopyPatrol because French articles were showing up =P Also it seems the comparison tool is loading enwiki articles and not frwiki. Also working some updates to the wikiproject bot task

Alrighty, T150904 and T150911 have been fixed, but new bugs were found: T150921, T150920, T150919. I also fixed a bug with MusikBot where it wasn't decoding the WikiProject names for frwiki, since they are parsed from links on the page.
