Symfony version(s) affected

All

Description

When the cache dirs don't exist (rm -fr var/cache/*) if you run the command bin/console cache:clear, Symfony runs cache warmers first and then deletes the entire cache (removing all the data created in the cache warmers).

If the cache dirs exist, Symfony does the right thing: first it clears the cache and then it runs the cache warmers.

Note: this is not a theoretical edge-case; this is impacting in real-world (see e.g. EasyCorp/EasyAdminBundle#6680)
