Some parallel worker jobs have not finished.

[yphoenix]

Seeing this error message: "Some parallel worker jobs have not finished." af the end of a PHPStan run, no actual PHPStan errors and only happens on the one machine.

Anybody have any clues as to how to work out what is causing it?

Thanks

When I run in debug mode --debug things look good and then the message Killed

[ondrejmirtes]

Any chance you're on Alpine 3.19? I've seen a similar issue recently which was fixed on Alpine 3.20.

Other than that it means the OS killed the process for some reason, maybe because of exhausted memory.

Try:

• running with bleeding edge which consumes less memory https://phpstan.org/blog/what-is-bleeding-edge
• lowering the number of processes https://phpstan.org/config-reference#parallel-processing

[yphoenix]

Running Ubuntu 22.04.4 LTS (Jammy Jellyfish), works just fine on macOS and RHEL8.
Using PHP 8.1
Cut the parallel processing to 1 already
Memory doesn't seem to be an issue, but who really knows.

[yphoenix]

Analyzing fewer files at a time does seem to help. It could indeed be memory related.

[andreypopov]

How to fix it? for me only "composer update" works somehow. Is there any other way?

It is really annoying during builds:

[ondrejmirtes]

The processes might be getting killed by Azure for some reason...

[ppaulis]

happened to me when a method defined in an interface wasn't correctly implemented :

public function setCreated(\DateTime $created): UserInterface;

vs.

public function setCreated(?\DateTime $created): UserInterface;

once I fixed this error, phpstan output went back to normal.

[ondrejmirtes]

You should have seen another error about that.

Try adding --memory-limit=2G

[pereorga]

I'm experiencing this since 1.11.6, on Mac, php 8.3.8. Changing the number of processes or the memory limit did not make any difference, and I am already using bleeding edge.

Can be reproduced in this public repository:

git clone git@github.com:Softcatala/pccd.git
cd pccd
# installs composer and other tools, via phive
tools/phive install
# installs phpstan 1.11.4, via composer
php tools/composer.phar install
# this works fine:
vendor/bin/phpstan --memory-limit=2G -vvv
# update phpstan
php tools/composer.phar require --dev phpstan@1.11.6
# this doesn't work, and it is slow:
vendor/bin/phpstan --memory-limit=2G -vvv

Note: Using configuration file /Users/pere/dev/pccd/phpstan.neon.

Used memory: 50 MB

The problem doesn't seem to be specific to a single file (if I delete src/common.php OR src/reports/directory, it does not fail).

@pereorga Isolated and reported here: #11292

[Kaikina]

Still having the same issue. It's raging to have no clues about the error. Memory isn't the problem.

[ondrejmirtes]

Hi, this isn't actionable feedback. It'd be best if you were able to reproduce this problem in GitHub ACtions.

[Kaikina]

For people having the same issue. My project is kind of special but who knows. I found the error, too bad PhpStan couldn't give me it.
I was requiring several autoloads and some of them had the same classes loaded.

[yphoenix]

I ran into this issue (again) recently (with the last couple of releases of PHPStan). Narrowed it down to one line in one file. Couldn't produce a simple reproducible case to submit, but can confirm that PHPStan can get in a "Hung" state and eventually times out. I ran it with the stack trace option, but the stack trace wasn't useful.

This was the code that caused this issue:

foreach ($res['csv'] as $idx => &$row)
{
	if (isset($row['id']))
	{
		// This blows up PHPStan so for this line only we access the array by index
		// $row['id'] = '<b>' . GetIDName($row['id']) . '</b>';

		$res['csv'][$idx]['id'] = '<b>' . GetIDName($row['id'] . '</b>';

I also had this problem ("Result is incomplete because of severe errors."), but only in PHPStorm popping up in notifications.
On command line everything looked fine. No errors were reported, no baseline.

I had introduced an interface for several classes using the same getters and setters and in some implementations the name did not match case wise, so the function in the interface was getXyZ() and the implemented version was getXyz().
I didn't realise this because no error was shown :).

I fixed that and now the error in PHPStorm notifications seems to have stopped.
Edit... nope it's back again :(.
But the point stands that the difference in upper and lower case wasn't reported.

I also found mismatches in type hinting ?string vs string... the also didn't show up in the errors, but this still doesn't make the error stop.

Is there any way to debug what phpstan is doing? It just says severe errors, but not which :(.

Edit again...
Found this one:
https://youtrack.jetbrains.com/issue/WI-80734/PHPStan-Improve-internal-quality-tool-errors-reporting
You got to dig up the full error message from .idea Log (https://intellij-support.jetbrains.com/hc/en-us/articles/207241085-Locating-IDE-log-files)...
At least gives you the file... but not the problem itself.

I'm getting the feeling that PHPStan doesn't like me creating getters and setters for properties that are just added via @Property annotations... Using Laravel here.

[nathaliemohrsynaigy]

-> Solution #11137 (reply in thread)

[nathaliemohrsynaigy]

@ondrejmirtes So I think I have narrowed it down to the access to magic properties in Laravel models.

This code will cause a severe error, both with and without the @Property annotation

<?php

declare(strict_types=1);

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

/**
 * @property int $id
 */
class Abc extends Model
{
    public function getId(): int
    {
        return $this->id;
    }
}

I would expect PHPStan to tell me off about accessing a not existing property (especially without the property annotation) instead of crashing.

I am currently running phpstan/phpstan on 2.1.20

[nathaliemohrsynaigy]

Here you go:
https://github.com/nathaliemohrsynaigy/laravel-sandbox
Added it to app/Models/User.php that comes with Laravel.
Interestingly enough I saw output of PHPStan here in PHPStorm, but it still kept giving me the Crash notice.
It only appears in PHPStorm, I used the phpstan.neon config here to let it run in Storm.

[ondrejmirtes]

I can't reproduce it:

laravel-sandbox main $ vendor/bin/phpstan
Note: Using configuration file /Users/ondrej/Downloads/laravel-sandbox/phpstan.neon.

 [OK] No errors

[nathaliemohrsynaigy]

Yes when I execute it on cli it also comes back with 0 errors.
But in the inspection running in PHPStorm it crashes :(

I just added a real error to the repo, this shows up when executing Stan on Cli but not in Storm.

Do you think I should raise the issue at Jetbrains instead?

[ondrejmirtes]

No, please try to recreate what PhpStorm does, it just runs PHPStan on CLI anyway so it should be reproducible on CLI. This isn't JetBrains's mistake.

[nathaliemohrsynaigy]

Ahhh finally....
I kept running phpstan through ddev.
I now ran it through the WSL2 host Ubuntu - which is configured in PHPStorm as for some reason running it directly on the containers is not supported - Now I'm getting the error I assume PHPStorm is running into:

     This message is coming from Laravel Framework itself.
     Larastan boots up your application in order to provide
     smarter static analysis of your codebase.

     In order to do that, the environment you run PHPStan in
     must match the environment you run your application in.

     Make sure you've set your environment variables
     or the .env file correctly.

So it is a Laravel issue that came with the update (and wasn't in the Upgrade Guide, yeah).
Needed to install the mbstring extension (laravel/framework#56478) now it works :).
No idea, though why PHPStorm does not give me this output, neither in the GUI, nor in the idea.log, would be so much easier if the error was just shown...
I guess Larastan somehow got into the equation when accessing the magic properties.

Thank you so much for your help <3.
