Bug description: File is missing 2048 bytes after fclose. When script ends the
file is complete
Description:
------------
Since I upgraded to PHP 5.2.10 I have got an problem with files not beiing
completly written. Exactly 2048 bytes are missing while the script is
running. Even after fclose it is not completley written.
If I open the file for reading again and then close it again the file is
complete. But that can't be correct... or is it?
Reproduce code:
---------------
$fh = fopen($pdf_tarfile, "wb");
$ch = curl_init(PDF_SERVICE_URL);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_FILE, $fh);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_exec($ch);
$return_code = curl_errno($ch);
if( $return_code ) {
trigger_error('curl returned error ' . $return_code . ': ' .
curl_error($ch), E_USER_ERROR);
return false;
}
curl_close($ch);
fclose($fh);
// It only works with this workaround
{
$fh = fopen($pdf_tarfile, "rb");
fclose($fh);
}
$cmd = 'tar'
. ' -x' // extract
. ' -f ' . escapeshellarg($pdf_tarfile) // this file
. ' -C ' . escapeshellarg($path); // into this directory
$stdout = array();
exec($cmd . ' 2>&1', $stdout, $return_code);
if ($return_code) {
trigger_error('tar returned error ' . $return_code . ': ' .
implode("\n",
$stdout), E_USER_ERROR);
return false;
}
Expected result:
----------------
Correctly unpacked tar archive.
Actual result:
--------------
Tar fails to unpack the file because it is missing the last 2048 Bytes.
If I run the command manually after the script is finished, the file can
be unpacked without any problem at all.
