Upgrade to Symfony 4.0
Scroll down to the script below, click on any sentence (including terminal blocks) to jump to that spot in the video!
With the deprecations gone... yeah! It's time to upgrade to Symfony 4! If you were hoping this was going to be really cool and difficult... sorry. It's super easy... well... mostly easy.
Open composer.json and change symfony/symfony to ^4.0. There are a few other libraries that start with symfony/, but they're independent and follow different release cycles. Oh, except for symfony/phpunit-bridge: change that to ^4.0 also.

Let's do this! Find your terminal and run:
composer update
Yep, upgrading is just that easy! Except... there are almost definitely some libraries in our composer.json file that are not yet compatible with Symfony 4. The best way to find out is just to try it! And then wait for an explosion!
Removing Alice
Ah! Here is our first! Look closely... this is coming from nelmio/alice: the version in our project is not compatible with Symfony 4. If we did some digging, we would find out that there is a new version of Alice that is compatible. But, that version also contains a lot of changes to Alice... and I don't like the library's new version very much. At least, not at this moment.
So, instead of upgrading, remove alice from composer.json. This will break our fixtures: we'll fix them later.
Update again!
composer update
Removing Outdated Libraries
Our next explosion! This comes from incenteev/composer-parameter-handler. This library helps you manage your parameters.yml file and... guess what? When we finish upgrading, that file will be gone! Yep, we do not need this library anymore.
Remove it from composer.json. Oh, also remove the distribution bundle: it helps support the current directory structure, and isn't needed with Flex. And below, remove the generator bundle. We'll install the new MakerBundle later.
Ok, update again!
composer update
When a Library is not Ready: StofDoctrineExtensionsBundle
It works! I'm just kidding - it totally exploded again. This time the culprit is StofDoctrineExtensionsBundle: the version in our project is not compatible with Symfony
- Now... we become detectives! Maybe the library supports it in a new version? Let's find out.
Google for StofDoctrineExtensionsBundle to find its GitHub page. Check out the composer.json file. It does support Symfony 4! Great! Maybe there's a new version that has this! Check out the releases. Oof! No releases for a long, long time.
This means that Symfony 4 support was added, but there is not yet a release that contains that code. Honestly, by the time you're watching this, the bundle probably will have a new release. But this is likely to happen with other libraries.
Actually, another common problem is when a library does not have Symfony 4 support, but there is an open pull request that adds it. In both situations, we have a problem, and you have a choice to make.
First... you can wait. This is the most responsible decision... but the least fun. I hate waiting!
Second, if there is a pull request, you can use that fork as a custom composer repository and temporarily use that until the library merges the pull request and tags a release. For example, imagine this pull request was not merged. We could add this as a vcs repository in composer.json, and then update the version constraint to dev-master, because the branch on the fork is master.
And third, since the pull request is merged, but there is no tag, we can simply change our version to dev-master. Believe me: I am not happy about this. But I'll update it later when there is a release.

Try to update again:
composer update
Ha! Look! It's actually working! Say hello to our new Symfony 4 app! Woohoo!
Upgrading old Packages
Oh, but check out that warning: the symfony/swiftmailer-bridge is abandoned. I don't like that! Hmm, I don't see that package in our composer.json file. Run:
composer why symfony/swiftmailer-bridge
Ah! It's required by symfony/swiftmailer-bundle. We're using version 2.3.8, which is apparently compatible with Symfony 4. But I wonder if there's a newer version?
Tip
Actually, version 2.3.8 is not compatible with Symfony 4. But due to an old issue
with its composer.json file, it appears compatible. Be careful with old libraries!
Google for the package to find its GitHub page. Click releases.
Woh! There is a new version 3 of the bundle. And I bet it fixes that abandoned packages issue. Change our version to ^3.1.

And now, update!
composer update
Because we're upgrading to a new major version, you'll want to check out the CHANGELOG on the project to make sure there aren't any major, breaking changes.
Yes! Abandoned package warning gone! And our project is on Symfony 4. Not bad!
But... get ready... because now the real work starts. And the fun! It's time to migrate our project to the Flex project structure!

Hey Gregory B.
There is a plugin for PhpStorm for composer support, it's called "PHP Composer.json support"
Cheers!

Hi Ryan, I'm getting a strange issue I wondered if you could help with:
Cannot autowire service "Twencha\Bundle\EventRegistrationBundle\Form\Registration\BaseRegistrationType": argument "$kernelEnv" of method "VisageFour\Bundle\ToolsBundle\Form\BaseFormType::__construct()" has no type-hint, you should configure its value explicitly.
However this is an abstract class firstly and secondly, the class isn't used as a service. I don't want to create a service definition for an abstract class! I also don't want to have to add this class to an "excludes" list as it shouldn't be trying to create a service. I cannot find any instances of it being used as a service and from what you said, only classes that are injected are put into the compiler. What should I do?

Hey Fox C.
If both classes BaseFormType and BaseRegistrationType are abstract classes and nobody is using or inheriting from them, then everything should work well. Can you double check that there isn't any "concrete" class extending from one of those? git grep "BaseFormType\|BaseRegistrationType should do the trick
Cheers!

Thanks, I searched my project - yes there are classes that extend these abstract classes. However, from my understanding, that's the point: to not be forced to create service definitions for abstract classes, but to create them for their children classes - I'm not sure why symfony would want to create a service for an un-instantiated abstract class, it's very strange.

Hey Fox C.!
This is a fascinating area of Symfony :). It does seem strange that Symfony would register an abstract class as a service. But it's done this way on purpose: someone could (in theory) use this "service auto-registration" feature to register an entire directory of abstract classes as abstract services:
App\AbstractStuff:
resource: '../src/AbstractStuff'
abstract: true
That's a total edge case, but it's valid.
But, back to your situation :). Because, even if the above is valid, it is super annoying that you would have this abstract class that is causing an error. Here's the trick: here's how this "should" be working internally in Symfony:
A) Symfony sees your class and registers it as a service
B) Some argument can't be autowired, so Symfony "attaches" an error to the service (it does not throw it... yet)
C) Symfony now notices that nobody ever uses your service, and so it removes it from the container
D) Symfony does not throw the exception from (B) because the service was removed from the container
And this happens all the time - it's why you could create a "model" class (e.g. src/Model/ProductInfo.php) with required constructor arguments and not get an error: this isn't meant to be a service, so you never use it as a service, so Symfony realizes it is not actually a service and removes it.
So the question is: why/what is "using" your BaseRegistrationType? You've already said that you are not using it as a service, and I believe you. But... Symfony is using it as a service. Because your form class ultimately implements FormTypeInterface::class, "autoconfigure" is automatically adding a form.type tag - thanks to this line in the core - https://github.com/symfony/symfony/blob/1de42a5f0806ee5291943ad8337e06d9a93c98a5/src/Symfony/Bundle/FrameworkBundle/DependencyInjection/FrameworkExtension.php#L430-L431
This ultimately means that Symfony's form system keeps a "reference" to your BaseRegistrationType service, which is not what you want. Honestly, I'm a bit surprised that I've never run into this or heard anyone running into this problem before. There are absolutely ways to work around this, but it is (I agree) an odd behavior (this auto-registration, autoconfigure stuff is tricky!). Unfortunately, unless I'm not seeing something, a work-around will be required. I can see 2 options:
1) Exclude the file like you originally suggested. Not ideal, but it will work
2) At the bottom of your services file, override the service and add abstract: true.
Anyways, I hope this helps at least clarify why you're seeing this odd behavior.
Cheers!

Hello SymfonyCasts Team, i know it's 2 years now, and i red that HHVM is dropped in symfony4, so i got this 2 problems :
1-This package requires php >=7.3.3 but your HHVM version does not satisfy that requirement, migrating to symfony4.
2- The requested package symfony/symony could not be found in any version, there may be a typo in the package name.
I don't know where to find HHVM.

Hey Abdallah O.
1.- I have no any particular experience in HHVM but you will have to pump up your PHP version of your machine somehow
2.- Since Symfony4 you don't install symfony/symfony package anymore, you just install the components or bundles that you will need. I recommend you to read about Symfony Flex so you get a better idea of what I'm talking about (https://symfony.com/doc/cur...

Hey Mark,
Is it the full output you have? What PHP version do you have? You can check it with "$ php --version" in your terminal. Also, could you show us your dependencies in composer.json?

friendsofsymfony/user-bundle (v2.0) is not compatible yet with SF4.
After doing the way that Ryan suggest for doctrine extension bundle it's working.
Also I noticed that it's Ryan was a major players into refactoring FOS userbundle for SF4 so it should be soon 'composer ready'.
Thank Ryan btw.
So use this line will make your project good to go : "friendsofsymfony/user-bundle": "dev-master"

I need php-ffmpeg/php-ffmpeg, which require neutron/temporary-filesystem, which allows only symfony/filesystem: ^2.3 || ^3.0
How could I solve?
(PHP-FFMpeg was required by pulse00/ffmpeg-bundle, which I already forked to allow SF4)

Hey toporovvv ,
Yes, you're right about PHP 7! Well, actually, Symfony 4 requires PHP ^7.1.3, but you have to point platform PHP version to that version you have on production. We just do not have this platform PHP version in our composer.json, but your comment may be useful for people who has. Thanks for sharing it!

Hi Ryan, thanks a lot for the great upgrade tutorial!
For me, I don'nt know exactly when it happened first, the cache is broken and it seems to have created an memory leak. If composer is starting clear:cache command the memory usage explode while creating the warmup-cache. I tried it on my local xampp-installation with 8GB Ram and with dev-server with 16GB RAM same issue. My next step was to check the memory_limit. This is fine to.
Do you have any hints how to debug/solve this?

Hey Thomas,
Yes, good step about checking memory limit, so what memory limit do you have? Here's some recommendations from Composer which probably can help: https://getcomposer.org/doc... - it worked for me. Also, do you have Xdebug installed? Did you disabled it during installation? See https://getcomposer.org/doc... . I'd also recommend you to upgrade to the latest Composer version available, I see it's 1.6.2.
Let us know if it does not help
Cheers!

Hi Victor,
thanks for suggestions. On DEV machine the memory limit for CLI is disabled and we increased the memory to 32G. Composer is neweset version. xdebug is installed and suggestions did not help also.
So now I've started from scratch with a new symfony 4 installation and copy related project files one by one and test results. What I saw while profiling is an heavy increase of nested functions while compiling cache. I've set value to 10000 (! default is 256 i mention !) and same issue. I mention that there is sleeping anywhere a small bug in symfony 4 code but I am not sure how to find him.
For now I will continue with my workaround above and maybe I can reproduce the behaviour and have more clue what file/function/class is causing this one.

Hey Thomas L.
How much swap memory do you have available? I experienced a somehow similar problem like this one in the past, and I managed to fix it by increasing the swap memory to 4GB
I hope it helps you. Cheers!

Hi MolloKhan,
2G swap but this is not the cause. If 32G RAM are fully used there must be another issue. I copied yesterday non-symfony-files (only my projectfiles) without configuration to a from-scratch-installation and tried it step by step to fullfill the configuration I need. And ... no issue. I have no clear whats going on but for now thats by dirthy workaround.

Hey Thomas L.!
That IS very strange and concerning.... and it *is* totally possible there's some sleeping bug in Symfony. I have a recommendation: try profiling with blackfire. You can even use Blackfire to profile a command you run at the command line: https://blackfire.io/docs/c.... I've done this many times, and it works awesome. THIS would be the way to find out what's causing the huge memory. I'd be very interested in knowing :).
Cheers!

Hello Ryan, could you tell us what PhpStorm plugin gives you the autocompletion on release versions of composer packages in composer.json ?
