Doctrine error: “Failed opening required '/tmp/__CG__Source.php' ”

Question

I am trying to migrate my PHP application to an Ubuntu server, but without succes. Any help would be appreciated.

First I installed Doctrine successfully into /jorrit/mya

TL;DR You'll just need to generate your proxy classes manually

vendor/bin/doctrine orm:generate-proxies

Doctrine uses Proxies to connect the to database. Proxies are generated from the the Entity classes.

In development mode, it generates a Proxies on every request because you could make changes to Entity classes.

In production mode, it does not generate Proxies every time. For performance reason, it assumes the Proxies exist and include them directly.

There are a few mode for Proxies generation:

1. ALWAYS - It alwayes generates Proxies, this is the default setting for development mode
2. NEVER - It never generates Proxies, this is the default setting for production mode
3. ON_DEMAND - It only generates the Proxies if the Proxy files do not exist. The drawback of this option is that it has to call file_exists() every time which could potentially cause a performance issue.

Now the command

vendor/bin/doctrine orm:generate-proxies

generates Proxy classes to /tmp. I would say this might still cause trouble because other applications on your server might delete these files unexpectedlly. One option is you can change your /tmp directory access permission to 1777

sudo chmod 1777 /tmp

The stricky bit '1' in front of 777 means that, although everyone can read/write to the /tmp directory, but you can only operate on your own files. i.e. You can't remove files created by other users.

For further reading, please have a look at http://docs.doctrine-project.org/en/latest/reference/advanced-configuration.html#auto-generating-proxy-classes-optional

You can also set the Proxies directory to somewhere else so no other applications can modify them. http://docs.doctrine-project.org/en/latest/reference/advanced-configuration.html#autoloading-proxies
