Bottle

Bottle is a really small python-based framework. The whole its code takes 1 file with ~4000 rows. Meanwhile, Bottle is pretty self-sufficient - it supports:

• wsgi-server
• routing
• authorization
• plugins
• own templates language
• a lot of extensions (mostly one-paged too)
• custom error pages
• and much more!

I was excited trying to write my blog using Bottle. The first issue I faced - you can login, but you can't logout :D

Bottle supports basic auth mechanism, so you can do something like:

def auth_callback(user, password):
    return user == password  # or any check you want

@bottle.auth_basic(auth_callback)
def edit_post(db, post_id):
    ....

But there is no way to logout. The only workaround I found is to return 401 status as a response. It allows to force logout the user. It's not quite correct, because user doesn't expect to get 401Error on logout, but this is why it's called workaround.

To make the solution to look more pretty I also customized 401 Error page, by adding an html-template with link to login.

def logout():
    return bottle.abort(401)

@app.error(401)
def error_401(error):
    return bottle.template("errors/401")

app.route("/logout/", ["GET"], logout)

As alternative, there is an extension for bottle, called bottle-login, which has been archived few years ago.
