"FIlename too long" error -- where does the 190 character limit come from?

[timstallmann]

Hi! I'm encountering "Filename too long" errors from this plugin on an Omeka site I maintain; there seems to be a 190 character hard limit on foldername + filename, but from my understanding most Linux filesystems have an unlimited path length and a 255 character limit on filenames -- is there any reason I couldn't patch this file to change the storageName length on my local install?

Here is the relevant bit of code, in ArchiveRepertoryPlugin.php:

if (strlen($storageName) > 190) {
    $msg = __(
        'Cannot move file "%s" inside archive directory: filename too long.',
        pathinfo($file->original_filename, PATHINFO_BASENAME)
    );
    throw new Omeka_Storage_Exception('[ArchiveRepertory] ' . $msg);
}
