Cache folder can no longer be a symlink in 2.3.15 #11011
Description
Today I was doing a composer update to go from Symfony 2.3.13 to Symfony 2.3.15 and since then I have been unable to run my application in my Vagrant environment.
The error I received is: MappingException: The mapping file /srv/shm/cache/dev/../../../vendor/symfony/symfony/src/Symfony/Component/Form/Resources/config/validation.xml does not exist
What apparently happened is that something, which I could not find, in Symfony had changed to generate relative paths in the cache instead of absolute paths.
However, to improve performance in vagrant we symlink the app/cache folder to /src/shm/cache in our virtual machine to reduce IO over vbox nfs. Having relative folders means now that it will try to find the vendor folder in my /srv/ folder.
Is this an unintended side-effect of another change? Is the above a supported use-case or should I find another way to improve performance in vagrant?
Here is the complete stacktrace (the name of the project has been replaced with dashes):
