Issue when saving files with long names containing dot in Django 5.1

Django Internals

With my Django Fellow hat on, I would say:

  1. Any custom “path splitting” logic added to this class could potentially introduce a future DoS risk in Storage.get_available_name, so I would advise against adding split_stem_suffix to the base Storage class.
  2. The base Storage class should ideally be filesystem-ignorant, and any further customizations should be evaluated for FilesystemStorage. (I understand this isn’t strictly the case at present in the Django code base, but we definitely shouldn’t make it worse.)
  3. Previous discussions have highlighted the need for redesigning the Storage API to enhance its extensibility, and we should consider this when making decisions on the topic. Related ticket is #35607. I have some concrete thoughts on this and maybe we can schedule a chat or open office hours or similar to go over this?

(We could also incorporate into the chat Document StorageHandler as public API. which is in my inbox, waiting, with a big red PENDING label.)
