Class 'WordPress\AbstractArrayAssignmentRestrictionsSniff' not found

[guillaumemolter]

Context:

• Fresh install via composer on my local machine (MacOS) and CircleCI (Ubuntu)
• Occurs with: master and develop branch, as well as 0.13 tag. Fixed when rolling back to 0.12 ( composer also rolls-back PHPCS to 2.9.1).
• How to reproduce:
  • composer install --no-interaction
  • vendor/bin/phpcs ./

Error:

Downgrading to squizlabs/php_codesniffer:2.9.1 fixes the issue.

[jrfnl]

@guillaumemolter I have a slight suspicion of why this is occurring for you, but I need more info to be sure.

1. When you run the composer install && vendor/bin/phpcs command, what version of PHPCS did this resolve to ?
2. Can you share the custom ruleset you are using ?
3. Probably not relevant, but just in case: On which PHP version are you running PHPCS ?

[guillaumemolter]

@jrfnl

1. Resolved to 3.0.2, rolling back to 2.9.1 fixed the issue.
2. See bellow
3. PHP 5.6.30 on my Mac and 7.0.4 on CircleCI

Ruleset:

<?xml version="1.0"?>
<ruleset name="HSPH WordPress Coding Standards">
    <config name="installed_paths" value="vendor/wp-coding-standards/wpcs"/>
    <exclude-pattern>*/vendor/*</exclude-pattern>
    <exclude-pattern>*/assets/*</exclude-pattern>
    <arg name="extensions" value="php"/>
    <!-- Include the WordPress ruleset, with exclusions. -->
    <rule ref="WordPress"></rule>
    <rule ref="WordPress.VIP">
        <exclude name="WordPress.VIP.PostsPerPage" />
        <exclude name="WordPress.VIP.RestrictedFunctions" />
    </rule>
    <rule ref="WordPress.WP.I18n">
        <properties>
            <property name="text_domain" type="array" value="hsph-plugin-custom-sidebar" />
        </properties>
    </rule>
    <rule ref="WordPress.WP.DeprecatedFunctions">
        <properties>
            <property name="minimum_supported_version" value="4.8" />
        </properties>
    </rule>
    <rule ref="WordPress.Files.FileName">
        <properties>
            <property name="is_theme" value="false" />
        </properties>
    </rule>
</ruleset>

[jrfnl]

Ok, this confirmed my suspicion. This is a known upstream issue - see: squizlabs/PHP_CodeSniffer#1582

In the mean time, it can easily be solved for you with a minor adjustment to your ruleset.

The WordPress ruleset already includes the WordPress-VIP ruleset, so there is no need to include it separately. Moving the exclusions you have up into the WordPress block should fix this.

In other words, replace :

    <rule ref="WordPress"></rule>
    <rule ref="WordPress.VIP">
        <exclude name="WordPress.VIP.PostsPerPage" />
        <exclude name="WordPress.VIP.RestrictedFunctions" />
    </rule>

with:

    <rule ref="WordPress">
        <exclude name="WordPress.VIP.PostsPerPage" />
        <exclude name="WordPress.VIP.RestrictedFunctions" />
    </rule>

On a completely unrelated side-note: happy to see you're using the new custom properties in your ruleset. You may want to add WordPress.NamingConventions.PrefixAllGlobals / prefixes and minimum_supported_version for WordPress.WP.DeprecatedClasses + WordPress.WP.DeprecatedParameters (all newly introduced in 0.12.0)

@jrfnl Ok thanks for the explanation. I've implemented the change to our ruleset. It makes sense when you think about it for more than 10 seconds :-). However this didn't fix the issue. How would I fix the issue via our ruleset? I can also keep using 0.12 for now.

Re custom prop: We welcome anything that can make our code more standard, future-proof and secure. I cannot stress enough how much our code base quality has improved since we have decided to strictly enforce WPCS using PHPCS and your tool. So thank you for all the good work and dedication.

[jrfnl]

However this didn't fix the issue. How would I fix the issue via our ruleset?

@guillaumemolter I've run some tests with your ruleset and I cannot reproduce the issue as long as you made the adjustment I suggested.

• I've tested with both PHPCS master and 3.0.2 + WPCS 0.13.0.
• I've tested with the installed_paths value in the ruleset both as an absolute as well as a relative path.

The only error I manage to get is:
ERROR: You must supply at least one file or directory to process.

And that's because neither the ruleset nor the command you supplied tell PHPCS which files to scan.
Changing the command to vendor/bin/phpcs . solved that and gave me the normal PHPCS report without errors.

Note: I didn't use Composer for the tests, but that shouldn't make any difference.

Ruleset I used:

<?xml version="1.0"?>
<ruleset name="HSPH WordPress Coding Standards">
    <config name="installed_paths" value="path/to/my/phpcs/install"/>
    <exclude-pattern>*/vendor/*</exclude-pattern>
    <exclude-pattern>*/assets/*</exclude-pattern>
    <arg name="extensions" value="php"/>
    <!-- Include the WordPress ruleset, with exclusions. -->
    <rule ref="WordPress">
        <exclude name="WordPress.VIP.PostsPerPage" />
        <exclude name="WordPress.VIP.RestrictedFunctions" />
    </rule>
    <rule ref="WordPress.WP.I18n">
        <properties>
            <property name="text_domain" type="array" value="hsph-plugin-custom-sidebar" />
        </properties>
    </rule>
    <rule ref="WordPress.WP.DeprecatedFunctions">
        <properties>
            <property name="minimum_supported_version" value="4.8" />
        </properties>
    </rule>
    <rule ref="WordPress.Files.FileName">
        <properties>
            <property name="is_theme" value="false" />
        </properties>
    </rule>
</ruleset>

[guillaumemolter]

I'm sorry but it still fails on both my computer and CircleCi. Yes the command was a typo from me, I've edited the OP with the correct command I actually use.

Here is my new ruleset (you will notice the new custom props :-P):

<?xml version="1.0"?>
<ruleset name="HSPH WordPress Coding Standards">
    <config name="installed_paths" value="vendor/wp-coding-standards/wpcs"/>
    <exclude-pattern>*/vendor/*</exclude-pattern>
    <exclude-pattern>*/assets/*</exclude-pattern>
    <arg name="extensions" value="php"/>
    <!-- Include the WordPress ruleset, with exclusions. -->
    <rule ref="WordPress">
        <exclude name="WordPress.VIP.PostsPerPage" />
        <exclude name="WordPress.VIP.RestrictedFunctions" />
    </rule>
    <rule ref="WordPress.WP.I18n">
        <properties>
            <property name="text_domain" type="array" value="hsph-plugin-custom-sidebar" />
        </properties>
    </rule>
    <rule ref="WordPress.NamingConventions.PrefixAllGlobals">
        <properties>
            <property name="prefixes" type="array" value="hsph" />
        </properties>
    </rule>
    <rule ref="WordPress.WP.DeprecatedFunctions">
        <properties>
            <property name="minimum_supported_version" value="4.8" />
        </properties>
    </rule>
    <rule ref="WordPress.WP.DeprecatedParameters">
        <properties>
            <property name="minimum_supported_version" value="4.8" />
        </properties>
    </rule>
    <rule ref="WordPress.WP.DeprecatedClasses">
        <properties>
            <property name="minimum_supported_version" value="4.8" />
        </properties>
    </rule>
    <rule ref="WordPress.Files.FileName">
        <properties>
            <property name="is_theme" value="false" />
        </properties>
    </rule>
</ruleset>

@guillaumemolter What about your composer.json file ? I've tested (again) with the updated ruleset and still cannot reproduce the issue, so I'm wondering if it is related to your Composer setup.
The fact that CircleCI does not easily seem to be able to determine the correct version to use for WPCS - even though it does seem to use the right commit in the end - also indicates a potential issue with the composer setup.

The ruleset itself is fine the way it is now and should not cause the fatal error.

Here is my new ruleset (you will notice the new custom props :-P):

👍

[jrfnl]

Hang on... I seem to have found the issue.

[jrfnl]

Ok, this is an upstream issue and we'll need to report it there. Jolly, you've found another bug with the autoloader....

Apparently, if installed_paths is set via the ruleset, things go haywire and PHPCS does not load "our" <autoload> file.

The simplest solution for now would be to install the suggested Composer plugin - dealerdirect/phpcodesniffer-composer-installer:^0.4.1 - to handle the installed_paths config for you.
You could then remove the <config...> directive for this from your ruleset, though based on my tests, leaving it in should do no harm either.

Let me know if that solves it for you.

[ervasive]

Can confirm, installation of dealerdirect/phpcodesniffer-composer-installer solved the issue for me.

[jrfnl]

@ervasive Thanks for letting us know.

[jrfnl]

I've reported the underlying issue upstream: squizlabs/PHP_CodeSniffer#1591

and pulled a temporary fix for now: #1090
