Override temporrary directory

[josephdpurcell]

Problem

After running phpstan, it tries to write it’s cache to the temporary directory, which is by default sys_get_temp_dir() . '/phpstan'. This may be an issue on filesystems that only have specific directories that are writable.

Proposed Resolution

Allow overriding the phpstan tmp directory.

Note: this is where phpstan looks for the tmpdir: https://github.com/phpstan/phpstan/blob/master/src/Command/CommandHelper.php#L104

You can set the tmpDir by modifying phpstan/base_config.neon and adding this line:

parameters:
    tmpDir: '/my/directory'

However, this requires modifying the drupal-check source, which not super flexbile.

Given that PHPSTan wants a single project file config (see CommandHelper), it would be difficult to expose a parameter to the drupal-check CLI that lets someone pass their own config file. The user would need to know what configs to put in their neon file.

What was the use case for this? Did people not have a writeable tmp directory?

[josephdpurcell]

I believe it had to do with containers and not having /tmp available. One suggestion was to use the temp directory of the Drupal install being inspected.

I have a need to change the temp path as well from the default of /tmp/phpStan/. I use drupal-check on a multi-user linux dev machine. When one of my teammates runs drupal-check it causes /tmp/phpStan/ to be filled with files owned by them. When I later go to run drupal-check I get permission errors due to ownership of the files in /tmp/phpStan/ and need to use the root account to delete the other user's temporary files before I can run it.

I'd like to be able to pass a temporary directory specific to my user account (either in my home directory or just /tmp/username-phpStan/ so that my execution of drupal-check isn't blocked by others'.

@adamfranco you should use phpstan directly probably and not use drupal-check to have more customization.

I've decided that this problem will not be fixed in drupal-check. Use PHPStan directly.
