Deprecated: Return type of Jack202505\Nette\Utils\DateTime::createFromFormat

[shakaran]

I think that it cames from upstream packages or used in composer like nette/utils, but not sure exactly which package brings the deprecated in your deps.

https://github.com/nette/utils/blob/master/src/Utils/DateTime.php#L96

 vendor/bin/jack open-versions
Analyzing "composer.json" for outdated packages

Deprecated: Return type of Jack202505\Nette\Utils\DateTime::createFromFormat(string $format, string $time, $timezone = null) should either be compatible with DateTime::createFromFormat(string $format, string $datetime, ?DateTimeZone $timezone = null): DateTime|false, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /srv/vendor/rector/jack/vendor/nette/utils/src/Utils/DateTime.php on line 67

Looking into this...

[TomasVotruba]

Let's see if this helps: #17

[TomasVotruba]

@shakaran Could you give 0.2.2 a try and let me know, how it works?

[shakaran]

Testing with 0.2.3 I get this:

$ vendor/bin/jack open-versions -vv
Analyzing "composer.json" for outdated packages

In Json.php line 58:

Thanks. What's the invalid json contents there?

[shakaran]

I put this debug in the nette file:

/**
     * Parses JSON to PHP value. The $forceArrays enforces the decoding of objects as arrays.
     * @throws JsonException
     * @param bool|int $forceArrays
     * @return mixed
     */
    public static function decode(string $json, $forceArrays = \false)
    {
        $flags = \is_int($forceArrays) ? $forceArrays : ($forceArrays ? \JSON_OBJECT_AS_ARRAY : 0);
        $flags |= \JSON_BIGINT_AS_STRING;
        var_dump($json);
        $value = \json_decode($json, null, 512, $flags);
        echo 'VALUE:' . PHP_EOL;
        var_dump($value);
        var_dump(\json_last_error());
        if ($error = \json_last_error()) {
            throw new JsonException(\json_last_error_msg(), $error);
        }
        return $value;
    }

This is the output:

It seems that the problem is mine, since via php.ini in docker is inyecting wrong the datetime, and the json is displaying that. Not sure if should be silenced at some part, for avoid this false positive errors
Warning: PHP Startup: Invalid date.timezone value 'TIMEZONE', using 'UTC' instead in Unknown on line 0

[TomasVotruba]

I see. I think your git/composer itself does that.
Ideally solve this on your end, as silencing errors might lead to some hidden bugs 👍

Hi,
Had the same issue. Just tested with 0.2.3 on 2 projects and it's all good.
Thanks!

[TomasVotruba]

Thanks for confirmation. Closing then
