The test failures are due to $this->handler being an instance of DummyHandler. This means the apcu driver's ->isSupported() call in CacheFactory returns false so you may want to debug there why it is not working on Github actions.

It seems to me that APCu extension just needs to be installed in the CI environment.

It seems to me that APCu extension just needs to be installed in the CI environment.

Please add then in test-phpunit.yml under the extra-extensions parameter of cache-live-tests job.

APCu enabled. Can't get why tests failed.

[paulbalandan]

Probably apcu_enabled() returns false?

[michalsn]

By default, APCu is disabled in CLI, see: https://www.php.net/manual/en/apcu.configuration.php#ini.apcu.enable-cli

We can use:

ini-values: apc.enable_cli=1

But this should be abstracted, like other options.

Thanks!
Please provide full details in the PR description.

This. Forgot about this parameter.

We can use:

ini-values: apc.enable_cli=1

But this should be abstracted, like other options.

Could you elaborate a bit? At first glance, I just wanted to add -d apcu.enable_cli=1 at the end of

CodeIgniter4/.github/workflows/test-phpunit.yml

Line 167 in 12cf2b4

extra-composer-options: ${{ matrix.composer-option }}

I don't think it will have any effect if you add it to the extra-composer-options.

The proper way to add ini settings to setup-php is by ini-values: https://github.com/marketplace/actions/setup-php-action#ini-values-optional

So I think we should have an abstract value, like: extra-ini-options, which will be applied when we setup php:

CodeIgniter4/.github/workflows/reusable-phpunit-test.yml

Lines 160 to 166 in 12cf2b4

	- name: Setup PHP
	uses: shivammathur/setup-php@v2
	with:
	php-version: ${{ inputs.php-version }}
	tools: composer
	extensions: gd, ${{ inputs.extra-extensions }}
	coverage: ${{ env.COVERAGE_DRIVER }}

I don't think it will have any effect if you add it to the extra-composer-options.

I was in a hurry and made a mistake. The composer parameters are of course irrelevant. I rather meant something like this
extra-phpunit-options: -d apcu.enable_cli=1

Thanks for the clarification. I'll look into this now.

[sk757a]

Time dependent test fail. May be just rerun?

[paulbalandan]

Can you also add ext-apcu in the suggested extensions in composer.json? Both root composer.json and framework composer.json

Thank you @sk757a
