#46846 [Opn]: Regex failure in run-tests

ID: 46846 Updated by: zoe@php.net Reported By: hannes dot magnusson at gmail dot com Status: Open Bug Type: *Configuration Issues Operating System: Linux PHP Version: 5.3.0alpha3 Assigned To: zoe New Comment: Ignore my previous comment. It not a PCRE problem, it's that the test is producing too much output. The behaviour of PCRE hasn't changed, but the test has. I have no idea how it ever passed in this form. Previous Comments: ------------------------------------------------------------------------ [2008-12-12 16:39:59] zoe@php.net Although the test isn't very good at it produces far too much output the problem is in preg_match() and did not exist in PHP 5.2.6.I believe that it was probably introduced when the PCRE library was upgraded to version 7.8. From the documentation for preg_match() the maximum length of a compiled pattern is 65539, preg_match() fails with pattern strings sizes somewhere between 29738 and 29310 characters, I'm not sure what the relationship is between the string length and the compiled pattern length. ------------------------------------------------------------------------ [2008-12-12 12:35:58] hannes dot magnusson at gmail dot com Description: ------------ Running ext/standard/tests/file/tempnam_variation4.phpt via run-tests.php causes regex compile failure.
