Bug #64793 [NEW]: finfo_open raises warning with env magic file

From: weierophinney Operating system: Ubuntu 13.04 PHP version: 5.4.14 Package: Filesystem function related Bug Type: Bug Bug description:finfo_open raises warning with env magic file Description: ------------ Using either the system magic file (/usr/share/file/magic.mgc) or the one shipped with PHP (http://lxr.php.net/xref/PHP_5_5/ext/fileinfo/tests/magic? r=12cf930a403d0bbee0c40a5e93554cafd6b0895e), and ensuring that my MAGIC env points to the file, any call to finfo_open() that does not specify a MIME file raises a warning: "offset `' invalid". This occurs in 5.3.3 and 5.4.14; I cannot reproduce it in 5.3.21. I've tried a variety of magic files, and not yet found one that works reliably across versions. Test script: --------------- $finfo = finfo_open(FILEINFO_MIME_TYPE); Expected result: ---------------- (no error) Actual result: -------------- finfo_open(): Warning: offset `' invalid -- Edit bug report at https://bugs.php.net/bug.php?id=64793&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64793&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64793&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64793&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64793&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64793&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64793&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64793&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64793&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64793&r=support Expected behavior: https://bugs.php.net/fix.php?id=64793&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64793&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64793&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64793&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64793&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64793&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64793&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64793&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64793&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64793&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64793&r=mysqlcfg
