Bug #81101 [NEW]: PCRE2 10.37 shows unexpected result
From: rlanting at move4mobile dot com
Operating system: MacOS 11.3.1
PHP version: 8.0.6
Package: PCRE related
Bug Type: Bug
Bug description:PCRE2 10.37 shows unexpected result
Description:
------------
This week I updated php and pcre through homebrew. As a result I got
pcre2 10.37. For that specific version preg_match doesn't work as
expected. Reverting only pcre2 to 10.36 makes it work again.
The regex originates from
https://github.com/phpspec/phpspec/blob/eb0d939b235f6091a8439a2a2fc144c9e0d5f569/src/PhpSpec/CodeAnalysis/TokenizedNamespaceResolver.php#L119
Homebrew issue: https://github.com/Homebrew/homebrew-core/issues/78635
Test script:
---------------
<?php
$matches = [];
$test = ' App\Domain\Repository\MetaData\SomethingRepositoryInterface';
preg_match('/\\\\([^\\\\]+)\s*$/', $test, $matches);
var_dump($matches);
$test2 = ' App\Domain\Exception\NotFoundException';
preg_match('/\\\\([^\\\\]+)\s*$/', $test2, $matches);
var_dump($matches);
Expected result:
----------------
array(2) {
[0]=>
string(29) "\SomethingRepositoryInterface"
[1]=>
string(28) "SomethingRepositoryInterface"
}
array(2) {
[0]=>
string(18) "\NotFoundException"
[1]=>
string(17) "NotFoundException"
}
Actual result:
--------------
array(0) {
}
array(2) {
[0]=>
string(18) "\NotFoundException"
[1]=>
string(17) "NotFoundException"
}
