Running into PHP memory limits when running `infection/infection` with this CI action

Bug Report

Q	A
Version(s)	1.11.4

Summary

When running infection/infection with this action, relatively low memory limits are hit in this job:

https://github.com/laminas/laminas-ci-matrix-action/blob/71aa5bef47be3a9d3e1a3865f43caf16708ed847/src/create-jobs.js#L175-L191

An example is visible at https://github.com/Roave/BackwardCompatibilityCheck/runs/4634739860?check_suite_focus=true#step:3:479

[PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 8192 bytes) in /github/workspace/vendor/symfony/finder/Iterator/RecursiveDirectoryIterator.php on line 69]

134217728 is 128Mb, which is something that is prohibitively low for PHP: we should really use -dmemory_limit=-1 here 🤔

Fixed downstream via Roave/BackwardCompatibilityCheck#372 - this is mostly about changing defaults, rather than a bug itself then? Unsure 🤔

[Ocramius]

Looks like setting {"ini": ["memory_limit=-1"]} does not suffice.

In Roave/BackwardCompatibilityCheck#372, the build still fails due to memory limits: https://github.com/Roave/BackwardCompatibilityCheck/runs/4634782919?check_suite_focus=true#step:3:479

The problem is potentially wrong evaluation in

laminas-continuous-integration-action/entrypoint.sh

Lines 171 to 174 in dadfeaf

	if [[ "${INI}" != "" ]];then
	echo "Installing php.ini settings"
	echo "$INI" > "/etc/php/${PHP}/cli/conf.d/99-settings.ini"
	fi

(perhaps changed/wrong file location?)

[Ocramius]

Found it: phpdbg does not load settings from /etc/php/$VERSION/cli, but from /etc/php/$VERSION/phpdbg, which we don't populate in

laminas-continuous-integration-action/entrypoint.sh

Lines 171 to 174 in dadfeaf

	if [[ "${INI}" != "" ]];then
	echo "Installing php.ini settings"
	echo "$INI" > "/etc/php/${PHP}/cli/conf.d/99-settings.ini"
	fi

Sending a patch shortly :)

Fixed via #67
