From: r dot staribacher at hypermove dot com Operating system: windows 2000/xp PHP version: 4.3.2 PHP Bug Type: Zlib Related Bug description: gzuncompress problem
Description: ------------ error occured on: OS: windows 2000 and xp webserver: apache and iis I am using a PHP class for reading pdf files. this class uses gzuncompress which causes problems on windows. IE displays the message "action canceled". Under Linux it "seems" to work. Parsing a large amount of pdf files also causes the process to stop. I have seen the Bug #20535: zLib crashes when trying to gzuncompress. So I tried to solve the problem using the optional length parameter. That didn't solve the problem. you can see or download the class on: http://www.phpclasses.org/browse.html/package/702.html I tried also xpdf (pdftotext.exe) to read PDFs using exec(), but another problem (unable to fork ...) occured! But this is not part of my bug report, but also annoying. One question: We can create PDFs using PHP! Why can't we read PDFs using PHP? It should be easier reading them instead of creating them? php.ini settings: savemode = off magic quotes = off no additional modules are activated (gzip is already compiled into php 4.3) Reproduce code: --------------- function nextline() { $pos = strpos($this->_buffer, "\r"); if ($pos === false) { return false; } $line = substr($this->_buffer, 0, $pos); $this->_buffer = substr($this->_buffer, $pos + 1); if ($line == "stream") { $endpos = strpos($this->_buffer, "endstream"); $stream = substr($this->_buffer, 1, $endpos - 1); $stream = gzuncompress($stream,1); $this->_buffer = $stream . substr($this->_buffer, $endpos + 9); } return $line; } Expected result: ---------------- The code will return an integer (how many times is the search expression in the pdf document). The original class returns true (found search expression) othewise false I think! -- Edit bug report at http://bugs.php.net/?id=25224&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25224&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25224&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25224&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25224&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25224&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25224&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25224&r=support Expected behavior: http://bugs.php.net/fix.php?id=25224&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25224&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25224&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25224&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25224&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25224&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25224&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25224&r=gnused
