Bug Type: Bug
Bug description:file_put_contents is not atomic.
Description:
------------
The function file_put_contents is not atomic. When the function fails a
file
should not be created. However, when the reason for failure is full
directory,
(full diskspace, 0 empty), the function return FALSE, but a file is still
created
in
the directory with size 0. The function should either complete the job
successfully or have no effects at all (atomic).
Test script:
---------------
$data = 'somedata';
$temp_name = '/tmp/myfile';
if (file_put_contents($temp_name, $data) === FALSE) {
// the message print that the file could not be created.
print 'The file could not be created.';
}
// after this a file named myfile will exist in the directory.
Expected result:
----------------
No file should be created
Actual result:
--------------
File is created in the directory.
