Subject: [PATCH 03/62] Tests: update to allow for running the tests on PHPCS
 4.x

As of PHPCS 4.0, the base sniff test class has been renamed from `AbstractSniffUnitTest` to `AbstractSniffTestCase`. Additionally, the PHPCS test setup no longer uses the outdated custom test suite creation.

This means that to allow for the tests to run on both PHPCS 3.x and 4.x, some changes are needed.

This commit handles this by:
* Changing all test files to `extend` the new test case class and adding a class alias to the test bootstrap for compatibility with PHPCS 3.x.
* Adding separate scripts to the `composer.json` file for invoking the tests on PHPCS 3.x vs 4.x.
* Updating the minimum PHPUnit 9 version to 9.3.4 as required by the PHPCS 4.x native test framework.
* Add jobs to test against PHPCS 4.x to all `test` matrices.
* Updating the `quicktest` and `unit-tests` jobs to use the correct Composer script based on the installed PHPCS version.

This commit also adds a step `unit-tests` to remove the `PHPCompatibility` dependency. This dependency is not needed in the tests and is currently not (yet) compatible with PHPCS 4.x, so it would block the `composer require`.

_Note: even though PHPCS 4.x supports PHPUnit 10 and 11, we cannot widen the version restrictions for PHPUnit (yet) while PHPCS 3.x is also supported as it would lead to PHPUnit 10/11 being installed for PHPCS 3.x on PHP >= 8.1, which would break the test runs._

Subject: [PATCH 04/62] PR 2619 DB/DirectDatabaseQuery: fix handling of
 namespaced calls to cache functions

Before this sniff was not properly differentiating between fully qualified calls to global WP cache functions, and namespaced calls to non-WP functions with the same name as the WP functions.

In other words, the sniff was correctly identifying `\wp_cache_get()` as a WP cache function, but it was incorrectly identifying `MyNamespace\wp_cache_get()` as a WP cache function. This commit fixes this issue.

This method was incorrectly identifying constant alias as the use of a global constant which is incorrect. This change aligns this method with how the sibling method in PHPCompatibility behaves.

Subject: [PATCH 30/62] CHECK WPDBTrait::is_wpdb_method_call(): update for
 PHPCS 4.0

The tokenization of (namespaced) "names" has changed in PHP 8.0, and this new tokenization will come into effect for PHP_CodeSniffer as of version 4.0.0.

This commit adds handling for the new tokenization of fully qualified calls to WPDB methods.

As there are no dedicated tests for this trait, a test will be added in a later commit that will update the `PreparedSQLPlaceholders` sniff for PHPCS 4.0. The test can't be added now because the sniff code needs to be updated as well to handle the new PHPCS 4.0 tokenization.

CHECK: I might end up adding dedicated tests for this method.

The tokenization of (namespaced) "names" has changed in PHP 8.0, and this new tokenization will come into effect for PHP_CodeSniffer as of version 4.0.0.

This commit adds handling for the new tokenization of fully qualified function/method calls when checking if the sniff can determine the key used to retrieve a value from the `$GLOBALS` array. The sniff was already handling this correct by chance due to a check that happens later in the code execution to bow out if `$var_name` is empty.

Subject: [PATCH 34/62] AbstractFunctionRestrictions: update for PHPCS 4.0

The tokenization of (namespaced) "names" has changed in PHP 8.0, and this new tokenization will come into effect for PHP_CodeSniffer as of version 4.0.0.

This commit adds handling for the new tokenization when checking if a given fully qualified function is a target function. In those cases, the leading backslash is removed from the token content to allow for the function name comparisons to continue working as they worked in PHPCS 3.x.

Subject: [PATCH 41/62] ConstantsHelper::is_use_of_global_constant(): update
 for PHPCS 4.0

The tokenization of (namespaced) "names" has changed in PHP 8.0, and this new tokenization will come into effect for PHP_CodeSniffer as of version 4.0.0.

This commit adds handling for the new tokenization when determining if a constant is global or not.

Subject: [PATCH 44/62] WIP NamingConventions/PrefixAllGlobals: improve prefix
 validation

Add a new error when validating prefixes if a prefix is not a string or is an empty string.

This is necessary in preparation for PHPCS 4.0. Starting with this version, array properties can have types other than string, and the sniff needs to be updated to handle non-string prefixes.

Using the same error when the string is empty made sense as before the sniff would generate an error complaining about the length of the prefix.

TODO: the value of the prefix is type casted to a string when displaying the error message. For example, `true` becomes `1`. I need to think if this is a problem or not.

Also, if `true` is passed as the first and only element of an array property there seems to be an error in PHPCS.

Check how https://github.com/PHPCSStandards/PHP_CodeSniffer/pull/1172 and https://github.com/PHPCSStandards/PHP_CodeSniffer/pull/1193 impact this commit.

Subject: [PATCH 45/62] WIP ContextHelper::is_in_function_call(): add basic
 tests

Check the way the tests are structured. There is for sure room to improve their organization.

Also check the way that I'm running the tests in the WordPress/Util/Tests in composer.json and the need to add a custom autoloader to bootstrap.php. There is probably a better way to achieve both.

Check the way the tests are structured. There is for sure room to improve their organization.

This commit is just the basic structured generated by Claude. Everything needs to be reviewed.

Subject: [PATCH 51/62] WIP ContextHelper::is_token_namespaced(): update for
 PHPCS 4.0

The tokenization of (namespaced) "names" has changed in PHP 8.0, and this new tokenization will come into effect for PHP_CodeSniffer as of version 4.0.0.

This commit adds handling for the new tokenization when determining if a token is namespaced or not. Since the tokenization of namespaced names changed between PHPCS 3 and 4, it was necessary to use different logic depending on the PHPCS version.

TODO check if the approach to support both PHPCS 3 and 4 is good.

Subject: [PATCH 52/62] WIP WPDBTrait::is_wpdb_method_call(): add basic tests

Check the way the tests are structured. There is for sure room to improve their organization.

This commit is just the basic structured generated by Claude. Everything needs to be reviewed.

Subject: [PATCH 54/62] PR 2631 WP/EnqueuedResourceParameters: fix handling of
 non-lowercased `null`

This commit fixes how the sniff handles non-lowercased `null` when passed as the value of the `$ver` parameter. Now the sniff consistently handles `null` regardless of the case and always returns a warning. Before, it would return a warning only for lower-cased `null` and an error for all other variations of `null`.

Subject: [PATCH 55/62] WP/EnqueuedResourceParameters: handle fully qualified
 `\false` and `\null` correctly

Before this change passing `\false` or `\null` as the `$ver` parameter would result in a false negative.

 names

I'm adding two different tests for fully qualified global function calls to cover all the global functions that are referenced directly in the `EnqueuedResourceParametersSniff::process_parameters` method.

Subject: [PATCH 58/62] DB/PreparedSQLPlaceholders: update for PHPCS 4.0

The tokenization of (namespaced) "names" has changed in PHP 8.0, and this new tokenization will come into effect for PHP_CodeSniffer as of version 4.0.0.

This commit adds handling for the new tokenization of fully qualified static calls to `wpdb::prepare()`, `sprintf()` and `implode()`.

Subject: [PATCH 62/62] DB/PreparedSQL: update for PHPCS 4.0

The tokenization of (namespaced) "names" has changed in PHP 8.0, and this new tokenization will come into effect for PHP_CodeSniffer as of version 4.0.0.

This commit adds handling for the new tokenization of fully qualified function calls and static method calls to this sniff.
