I have installed the phabricator, and when browser form browser, encounter exception "openssl_random_pseudo_bytes() returned an unexpected number of bytes (got %d, expected %d)". after verification it happened in" /libphutil/src/filesysem/Filesysem.php in method readRandomBytes (line 392)
$data = openssl_random_pseudo_bytes($number_of_bytes, $strong);
if (!$strong) {
// NOTE: This indicates we're using a weak random source. This is
// probably OK, but maybe we should be more strict here.
}
if ($data === false) {
throw new Exception(
pht('openssl_random_pseudo_bytes() failed to generate entropy!'));
}
if (strlen($data) != $number_of_bytes) {
throw new Exception(
pht(
'openssl_random_pseudo_bytes() returned an unexpected number of '.
'bytes (got %d, expected %d)!',
strlen($data),
$number_of_bytes));
}Is it a bug here, strlen will return string's length, not the bytes length, so it always return exception.
I tried to comment out the lines, the issue gone. but hit another issue to connect with my mysql which should not relate with this.
Can anyone have a look? thanks.
