Jump to Symfony 4.4

[j0k3r]

Migration was pretty easy, only few steps were a bit more complex.
In fact, if you've already managed all deprecated messages in the past, you won't have much code to change, mostly configuration.

Most of job can be done following different doc:

• https://symfony.com/doc/4.4/setup/upgrade_major.html
• https://symfony.com/doc/4.4/setup/flex.html
• https://github.com/symfony/symfony/blob/4.0/UPGRADE-4.0.md
• https://github.com/symfony/demo (which helps a lot)

The most boring step is to move the previous config files to the new structure and split them in many small files.

Also some bundles might not be allowed to be installed for Symfony 4, which require a PR (see AshleyDawson/SimplePaginationBundle#7)

Few things that bothered me:

• I wasn't using a mappings for Doctrine before and I spend some time understanding some issue. Found it on the symfony/demo.
• I got a complex issue where logged in user during tests weren't working anymore. The issue were with the logout_on_user_change security parameter which went from false to true by default. During the login process, the logged in user wasn't detected as the same and got logged out. Which means I wasn't able to login at all. SO helped me I was forced to implement the isEqualTo method to check myself if the user changed (and if important stuff changed between the two).

There is massive additions mostly found in composer.lock.

Also:

• Fixtures moved into a single file, I found more easy to understand and avoid having to remember which order between fixtures.
