Bug description:CRC32 Error not reported
Description:
------------
I corrupted a file using a hex editor.
"echo shell_exec('unzip -t file')" shows the CRC32 mismatch.
ZipArchive::extractTo() doesn't report CRC32 errors.
Reading a stream received from ZipArchive::getStream('myfile') echoes a CRC
error if the number of bytes read with one fread() is below 2157 bytes.
Test script:
---------------
$zip = new ZipArchive();
if ($zip->open('test.zip')) {
zip->extractTo('mydir'); //no error printed
$fp = $z->getStream('brokenfile');
while (!feof($fp)) {
$buf .= fread($fp, 2048+108); //CRC error printed
}
$fclose($fp);
$fp = $z->getStream('brokenfile');
while (!feof($fp)) {
$buf .= fread($fp, 2048+109); //CRC error NOT printed
}
$fclose($fp);
zip.close()
}
Expected result:
----------------
A CRC32 error report that can be handled.
The one from "fread($fp, 2048+108)" is fine: "Warning: fread()
[function.fread]: Zip stream error: CRC error in ..." (can be handled with
"ob_get_contents()");
For "ZipArchive::extractTo()" the corrupt file(s) should be printed.
Actual result:
--------------
CRC32 errors are reported always.
