Hello,

Yesterday I've used wp core update to update a site from 4.1.1 to 4.2.2. The update went through and after a wp core update-db the system also stated that it is now running 4.2.2. However the site and admin tool was partially broken as the update pulled just incremental changes between 4.2.1 and 4.2.2 and did not pull the changes from 4.2 and all the other versions between 4.1.1 and 4.2.2.

After I manually copied all core files from a blank new install the site worked bug free.

I'm not sure if this is the intended mechanism? How would I ensure to apply all incremental changes between two versions? How could I force to download the full install?

I remember to have seen a notification that wp-cli was using a cached file in ~/.wp-cli/cache/core
Unfortunately I can't remember which file has been used. As you can see the following files are in this folder. All would have been pulled by wp-cli (probably sometimes used in a sudo command).

-rw-r--r--  1 novazembla  staff  6183711 28 Jan 13:51 en_US-4.1.tar.gz
-rw-r--r--  1 novazembla  staff  6321767  5 May 22:18 en_US-4.2.1.tar.gz
-rw-r--r--  1 root        staff  6307937  8 Jun 17:40 en_US-4.2.2.tar.gz
-rw-r--r--  1 novazembla  staff   519434 15 Jun 13:29 en_US-4.2.2.zip

Looking at the file sizes I assume that it has been using the .zip file.

Is there a way to ensure that wp core update always updates all changes between two versions.

Thanks!
