#595 text is limited in length

[Stefan Schorn]

in phpwiki cvs version there seems to be a problem with long texts in phpwiki.

For testing purposes the text should be in one part (no crlf) and more than 2000 signs long.

after saving the text, the text is no longer shown. when editing the page again the text is there again ...

after days of trying to solve the bug i gave up and returned to php4. The same bug is present in phpwiki 1.3.14 final also.

after spending 200€ to come nearer to a solution, it seems to be a problem of $hugepat (line 82) in InlineParser.php.

the function in line 185 closes with false when the line is to long. After making $hugepat shorter the text can be longer ...

strange part of code there

I have rewrote the stupid function _match in InlineParser.php. for me the limit is brocken and all seems to work. If someone is interested at the solution here is the code

function _match ($text, $regexps, $repeat) {
    $posold = -1;
    $match = new RegexpSet_match;
        for ($i=0; $i < count($regexps); $i++) {                
                    if (!trim($regexps[$i])) {
                        trigger_error("empty regexp $i", E_USER_WARNING);
                        continue;
                    }
                    $pat= "/ ( . $repeat ) ( " . $regexps[$i] . " ) /Asx";
                    if (preg_match($pat, $text, $m)) {
                if ($m[2]) {
                        $posakt = strpos($text, $m[2]);
                        if ((($posakt < $posold) || ($posold == -1)) && $m[2]){ 
                                    $posold = $posakt;
                                    $match->prematch = substr($text,0,$posakt);
                                    $delpart = substr($text,0,$posakt).$m[2];       
                                    $match->postmatch = substr($text, strlen($m[0]));
                                    $match->match = $m[2];
                                    $match->regexp_ind = $i;
                            }
                            }   else {
                                    $match->prematch = $text;
                                    $match->match = "";
                                    $match->regexp_ind = 0;
                                    $match->postmatch = "";
                            }
                    }
        }
        if (empty($match)) return false;
    return $match;
}
