#### Description
This extension checks to see if a logged in editor qualifies for access to [[ https://wikipedialibrary.wmflabs.org/ | The Wikipedia Library ]] by checking their account age and global edit count. The first time they become eligible, it sends them a notification about it.
#### Preview environment
https://en.wikipedia.beta.wmflabs.org/wiki/Main_Page
This has been deployed to beta cluster. It is currently configured to notify editors when they reach 100 edits with an account that is at least one day old.
#### Which code to review
https://gerrit.wikimedia.org/r/mediawiki/extensions/TheWikipediaLibrary
#### Performance assessment
Please initiate the performance assessment by answering the below:
- What work has been done to ensure the best possible performance of the feature?
- None, will update with details when we have done so.
- What are likely to be the weak areas (e.g. bottlenecks) of the code in terms of performance?
- We're doing an extra read + write to global preferences on save in a pretty common case. This was originally sending duplicate notifications on beta do to silent failures to read/write global prefs, and this workaround ensures that we only send if we're **really** sure that globalprefs is working correctly.
- Are there potential optimisations that haven't been performed yet?
- We could potentially do a more efficient globalprefs check if we were ever able to reproduce the duplicate notifications outside of beta
- Please list which performance measurements are in place for the feature and/or what you've measured ad-hoc so far. If you are unsure what to measure, ask the Performance Team for advice: [[ mailto:performance-team@wikimedia.org | performance-team@wikimedia.org ]].
- We have emailed the performance team as recommended, but have not heard back yet
