PhpMetrics v3.0.0-rc6 hanging

[andrii-pukhalevych]

Bug report

PhpMetrics v3.0.0-rc6
Composer version 2.8.1 2024-10-04 11:31:01
PHP version 8.1.29

I created directory PhpMetricsDemo with single class Hello inside:

<?php
class Hello {

	public function start(): void {
		echo 'start';
	}
}

Call of PhpMetrics/bin/phpmetrics PhpMetricsDemo results hanging after output

Hanging seems to be caused by Composer analyzer, because composer is not present in my folder.
It should not happens, not all projects have composer.

Tested with your snippet using Docker image PHP php:8.1.29-cli and PhpMetrics v3.0.0-rc6 and got no issue (Docker image doesn't have Composer installed).

> docker container run -it --rm -v /tmp/:/app/ -v ~/Projects/GitHub/phpmetrics/PhpMetrics:/phpmetrics --workdir=/app/ php:8.1.29-cli /phpmetrics/bin/phpmetrics PhpMetricsDemo

Done

Are you sure about your path? It could be hanging because lots of files are being analyzed.

What application was used? I my case it was app with single class, but without composer.json/vendor. In system composer was installed.

I created a folder in /tmp only with your Hello class (in Hello.php), copy/pasted from this ticket.
Nothing more, nothing less. No composer.json, no composer.lock, no vendor folder. Plus, the Docker image I used doesn't have composer installed.
I firstly tried with another image with composer installed in system (i.e exactly your status), but I didn't report it here because I thought you didn't have composer at all. Anyway, in the 2 cases, PhpMetrics in v3.0.0-rc6 is behaving as expected.

[andrii-pukhalevych]

Thanks for checking. I found halt reason: I call PhpMetrics/bin/phpmetrics PhpMetricsDemo from directory with many projects. So composerJsonFinder->fetch() in getComposerJsonRequirements() returns composer.json files from all of these projects, not from PhpMetricsDemo only.

Not sure if it bug or another way of phpmetrics launch should be used.

This might be a bug similar to #463

I already gave it a try on it but I need to spend more time, and I can't find it right now.

In the meantime, try to run your command being located on your project folder only and it should be OK. Sorry for the inconvinience about it.
