#37335 [Fbk->Bgs]: zip_entry_read handling of null byte

ID: 37335 Updated by: pajoye@php.net Reported By: humbads at alum dot mit dot edu -Status: Feedback +Status: Bogus Bug Type: ZZiplib Related Operating System: FreeBSD 4.7 RELEASE PHP Version: 4.4.2 Assigned To: pajoye New Comment: Thank you for taking the time to report a problem with PHP. Unfortunately you are not using a current version of PHP -- the problem might already be fixed. Please download a new PHP version from http://www.php.net/downloads.php If you are able to reproduce the bug with one of the latest versions of PHP, please change the PHP version on this bug report to the version you tested and change the status back to "Open". Again, thank you for your continued support of PHP. I cannot reproduce your problen with the latest Zip release. Your zip works with php 4.4 and 5.1.x. I can read and extract the image. I also recommend to use the new API with php 5.1+. It is more efficient and you can extract directly to the disk. You can fetch the latest release from the PECL site: http://pecl.php.net/package/zip If you still have troubles, please reopen this bug.

Thank you for helping us make PHP better. Which version(s) of the zip package do you use? ------------------------------------------------------------------------ [2006-05-05 21:15:37] humbads at alum dot mit dot edu Description: ------------ When using zip_entry_read to decompress a zip entry containing a null byte, the function only returns data up to the first null byte in the decompressed file. Bug does not occur on PHP 5.1.2 for Windows XP. Reproduce code: --------------- <?php dl("zip.so"); // test.zip contains one file with a null byte in the middle $zipfile = zip_open("onejpg.zip"); $zipentry = zip_read($zipfile); zip_entry_open($zipfile, $zipentry); $content = zip_entry_read($zipentry, zip_entry_filesize($zipentry)); print "filesize: ".filesize("onejpg.jpg")."\n"; print "variable: "; var_dump($content); zip_entry_close($zipentry); zip_close($zipfile); ?> Expected result: ---------------- var_dump should show a string with the same length as the file size. To download onejpg.zip and onejpg.jpg, go here: http://www.somacon.com/p258.php http://www.somacon.com/p257.php Actual result: -------------- var_dump only shows length 4, which is the length up to the null byte. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37335&edit=1
