Description (last modified by ocean90)

Related: #34432, #36335

trunk/src/wp-admin/includes/class-wp-upgrader-skins.php includes WP_Upgrader_Skin, Plugin_Upgrader_Skin, Bulk_Upgrader_Skin, Plugin_Installer_Skin, Theme_Installer_Skin, Theme_Upgrader_Skin, Language_Pack_Upgrader_Skin, and Automatic_Upgrader_Skin.

trunk/src/wp-admin/includes/class-wp-upgrader.php includes WP_Upgrader, Plugin_Upgrader, Theme_Upgrader, Language_Pack_Upgrader, and Core_Upgrader.
The same file includes also File_Upload_Upgrader and WP_Automatic_Updater which are not a subclass of WP_Upgrader and the file includes class-wp-upgrader-skins.php.

Sadly, the naming of the classes isn't quite good because they don't have a unique prefix.

Based on the current naming schema we'd have the following new and old files:

wp-admin/includes/class-wp-upgrader.php // Includes WP_Upgrader and requires files below except fo class-wp-upgrader-skins.php.
wp-admin/includes/class-plugin-upgrader.php
wp-admin/includes/class-theme-upgrader.php
wp-admin/includes/class-language-pack-upgrader.php
wp-admin/includes/class-core-upgrader.php
wp-admin/includes/class-file-upload-upgrader.php
wp-admin/includes/class-wp-automatic-updater.php
wp-admin/includes/class-wp-upgrader-skins.php // Only for back-compat, requires files below.
wp-admin/includes/class-automatic-upgrader-skin.php
wp-admin/includes/class-wp-upgrader-skin.php
wp-admin/includes/class-bulk-upgrader-skin.php
wp-admin/includes/class-bulk-plugin-upgrader-skin.php
wp-admin/includes/class-bulk-theme-upgrader-skin.php
wp-admin/includes/class-language-pack-upgrader-skin.php
wp-admin/includes/class-plugin-upgrader-skin.php
wp-admin/includes/class-theme-upgrader-skin.php
wp-admin/includes/class-plugin-installer-skin.php
wp-admin/includes/class-theme-installer-skin.php

Thoughts?

+100. The prefix doesn't matter too much, as they have a common suffix. (I have a autoloader written that already handles that. :) )

Splitting it would be pretty useful, although has the potential to break currently if someone is loading the file directly. That could be fixed by using an autoloader (#36335) to ensure the class is available regardless of what files are loaded manually.

Replying to rmccue:

Can you elaborate on this? In my approach class-wp-upgrader.php will continue loading all the files.

#3 @rmccue

Just a general comment about splitting, not to this specific ticket. :)

#4 @ocean90

  • Keywords early added

Noting here that this needs some extensive testing on how it could affect a core upgrade.

@dd32 Any thoughts on this?

#5 @dd32

I have no objections, to either the main file just including everything else, or using a autoloader (probably in the future - Sorry there wasn't a common prefix!)

The only potential issue would be an incomplete failed update which then couldn't be completed from within wp-admin. As it is, the chances of a failed *major* update leaving WordPress in a state that WordPress can update itself again is rather slim.

Let's do this in stages. Each stage is one commit.

1) Create wp-admin/includes/class-automatic-upgrader-skin.php, wp-admin/includes/class-bulk-plugin-upgrader-skin.php, wp-admin/includes/class-bulk-theme-upgrader-skin.php, wp-admin/includes/class-bulk-upgrader-skin.php, wp-admin/includes/class-language-pack-upgrader-skin.php, wp-admin/includes/class-plugin-installer-skin.php, wp-admin/includes/class-plugin-upgrader-skin.php, wp-admin/includes/class-theme-installer-skin.php, wp-admin/includes/class-theme-upgrader-skin.php, and wp-admin/includes/class-wp-upgrader-skin.php as a copy of wp-admin/includes/class-wp-upgrader-skins.php.
2) Update file headers and DocBlocks for each new file.
3) Change wp-admin/includes/class-wp-upgrader-skins.php to require_once all the new files and update file header.

4) Create wp-admin/includes/class-plugin-upgrader.php, wp-admin/includes/class-theme-upgrader.php, wp-admin/includes/class-language-pack-upgrader.php, wp-admin/includes/class-core-upgrader.php, wp-admin/includes/class-file-upload-upgrader.php, and wp-admin/includes/class-wp-automatic-updater.php as a copy of wp-admin/includes/class-wp-upgrader.php.
5) Update file headers and DocBlocks for each new file.
6) Change wp-admin/includes/class-wp-upgrader.php to only include WP_Upgrader and add require_once for all the new files (upgrader and skins). Update file header.

7) If necessary, update file paths for hook docs.
8) Check references to include/require wp-admin/includes/class-wp-upgrader.php and if they can be changed to include/require only necessary files. File_Upload_Upgrader might to be one of those.

Replying to ocean90:

8) Check references to include/require wp-admin/includes/class-wp-upgrader.php and if they can be changed to include/require only necessary files. File_Upload_Upgrader might to be one of those.

File_Upload_Upgrader is only used in /wp-admin/update.php which has an include_once for class-wp-upgrader.php on top. WP_Automatic_Updater is another class which is not a subclass of WP_Upgrader but it's using skins and other upgraders.
For now, we have to continue loading wp-admin/includes/class-wp-upgrader.php until we have an autoloader, see #36335.

#20 follow-up: @swissspidy

@ocean90 Attention! [37411] broke update functionality in core.

There's a $package = ''; line in WP_Upgrader::download_package(), probably a leftover from debugging.

#21 @ocean90

In 37413:

Upgrader: Remove debug cruft.

See #36618.
