Change tool installation directory

[Sn0wCrack]

Right now all tools, such as composer, get installed globally to /usr/local/bin.

On self-hosted runner systems with multiple runner users, this can cause issues as it appears all tools are re-downloaded every time the action is executed.

Is there currently any way to change the install path to another directory, such as ~/.local/bin or /tmp?

Looking at the code I believe this may be hard coded currently: https://github.com/shivammathur/setup-php/blob/main/src/scripts/tools/add_tools.sh#L2

I can't seem to see anything else that overrides this value currently.

Can you reproduce the issue on a public repo and provide me the logs with shivammathur/setup-php@verbose. I would like to understand this better.

@Sn0wCrack Please run it once again, I would like to see the logs.

@shivammathur

Here's a run where it failed: https://github.com/Sn0wCrack/setup-php-multi-runner-users-reproduction/actions/runs/11785460085

The last 3 runs should be of interest in this case.

[shivammathur]

It should install correctly now.

@shivammathur That seems to be working now, last 5 runs seem to be good, thank you very much!

Actually this might have been a fluke, it appears other processes may use composer at a later point and be kicked back with a "text file busy" error on composer.

I still think it might be better to allow setting the tool directory (to say ~/.local/bin) so each runner user gets their own copy. Wasteful I know, but it will mean each one can act independently.
