#39951 [NEW]: PCRE Failed for Long Matches (Less Than MATCH_LIMIT)
From: imacat at mail dot imacat dot idv dot tw
Operating system: Linux 2.6.16.29
PHP version: 5.2.0
PHP Bug Type: PCRE related
Bug description: PCRE Failed for Long Matches (Less Than MATCH_LIMIT)
Description:
------------
Hi. This is imacat from Taiwan. I experienced PCRE failure after
long matches. It doesn't seems to pass the 50000 match limit, UTF-8 or
not. However, looking into the included PCRE library directory I saw no
such limit anywhere. In config0.m4 the setting is
-DMATCH_LIMIT=10000000. In pcrelib/README it states that the default of
--with-match-limit is 500000. In php.ini I saw
pcre.backtrack_limit=100000. Whatever I saw are far less than the 50000
match limit.
This is hard to me since I have several articles to be parsed that's
of size over 50000 bytes/characters.
Reproduce code:
---------------
#! /usr/bin/php
<?php
echo "=== Test #01 Non-UTF-8\n";
$a = str_repeat("a", 49997);
echo "1. \"a\" repeated 49997 times\n";
printf(" strlen(): %6d, preg_match(): %d\n",
strlen($a), preg_match("/^(.*?)\s*$/us", $a));
$a = str_repeat("a", 49998);
echo "2. \"a\" repeated 49998 times\n";
printf(" strlen(): %6d, preg_match(): %d\n",
strlen($a), preg_match("/^(.*?)\s*$/us", $a));
echo "=== Test #02 UTF-8\n";
$a = str_repeat("\xE4\xB8\x80", 49997);
echo "1. \"\\xE4\\xB8\\x80\" repeated 49997 times\n";
printf(" strlen(): %6d, preg_match(): %d\n",
strlen($a), preg_match("/^(.*?)\s*$/us", $a));
$a = str_repeat("\xE4\xB8\x80", 49998);
echo "2. \"\\xE4\\xB8\\x80\" repeated 49998 times\n";
printf(" strlen(): %6d, preg_match(): %d\n",
strlen($a), preg_match("/^(.*?)\s*$/us", $a));
?>
Expected result:
----------------
=== Test #01 Non-UTF-8
1. "a" repeated 49997 times
strlen(): 49997, preg_match(): 1
2. "a" repeated 49998 times
strlen(): 49998, preg_match(): 0
=== Test #02 UTF-8
1. "\xE4\xB8\x80" repeated 49997 times
strlen(): 149991, preg_match(): 1
2. "\xE4\xB8\x80" repeated 49998 times
strlen(): 149994, preg_match(): 0
Actual result:
--------------
=== Test #01 Non-UTF-8
1. "a" repeated 49997 times
strlen(): 49997, preg_match(): 1
2. "a" repeated 49998 times
strlen(): 49998, preg_match(): 1
=== Test #02 UTF-8
1. "\xE4\xB8\x80" repeated 49997 times
strlen(): 149991, preg_match(): 1
2. "\xE4\xB8\x80" repeated 49998 times
strlen(): 149994, preg_match(): 1

Well.... This must be some kind of blind spot. I spent a lot of time
finding out the configuration setting, but have never thought of
altering it.
It seems to solve the problem. I'm terribly sorry for the bothering.
