WordPress/wp-admin/includes/update-core.php
John Blackbourn a027edc277 Comments: The year is 2003. Permalinks are a new thing and everyone's using Blogger. It's a time when opening a modal window in JavaScript to view a section of a website is not a completely weird thing, although many users get annoyed by it. b2 has recently become WordPress, and with it comes a bunch of functionality that will become stale over the next decade, remnants of simpler times.
Twelve years later, after no fewer than three themes have intentionally implemented popup comments in their functionality, before being abandoned for at least the last six years, we've reached a time where we can put this era behind us. A time when we can remove comment popup functionality from WordPress.

If this breaks the internet, I'll eat my hat.

Fixes #28617

* 1. Test unzipped location for select files to ensure that unzipped worked.
* 2. Create the .maintenance file in current WordPress base.
* 3. Copy new WordPress directory over old WordPress files.

* 5. Delete new WordPress directory path.
* 6. Delete .maintenance file.
* 7. Remove old files.
* 8. Delete 'update_core' option.

* 6, then you will not be able to access any portion of your site. Also, since
* the upgrade will not continue where it left off, you will not be able to
* automatically remove old files and remove the 'update_core' option. This
* isn't that bad.
*
* If the copy of the new WordPress over the old fails, then the worse is that
* the new WordPress directory will remain.
*
* If it is assumed that every file will be copied over, including plugins and
* themes, then if you edit the default theme, you should rename it, so that
* your changes remain.
