pcdavid / niouz

Adding new groups currently requires manual editing of a text file. It should be possible to do it using a command, possibly a variant of the main launcher, like:

% niouz groups add --name="test.example" --description="A short description of the group's topic."

Currently groups can only be added. It should be possible to remove them, using something like:

% niouz groups remove test.example

By default, such a command would fail if there are articles in the group. An optional flag would force the removal of the group and of all its contents.

The current storage format is very primitive. The first step towards replacing it with better ones is to decouple the main server code from the storage code, and extract a well-defined Storage abstraction/API.

The server does not currently allow for users to cancel articles.

Should canceled articles be immediatly removed from the storage, or maybe kept until an explicit purge/gc action is performed by the admin?

The code to read/write messages currently needs their whole contents to be in memory. This is not realistic if niouz is to be used e.g. to share big binary files in a workgroup. The server should be able to work with a bounded memory amount (maybe configurable?).
