Bug description: feof never returns true for damaged file in zip
Description:
------------
Opening a damaged zip archive (7z reports CRC failed for the faulty file),
feof never return true, the script blocks, causing high CPU usage.
Please contact me to get a zip that produces this problem. I don't see how
can i attach it here
Reproduce code:
---------------
$o = new ZipArchive();
if (! $o->open('test.zip',ZipArchive::CHECKCONS)) {
exit ('error can\'t open');
}
$o->getStream('file2'); // this file is ok
echo "OK";
$r = $o->getStream('file1'); // this file has a wrong crc
while (! feof($r)) {
fread($r,1024);
}
echo "never here\n";
Expected result:
----------------
The script either reads the file ignoring the crc error, or reports the
error, but finishes.
Actual result:
--------------
the script never ends, and uses up the CPU
