Why babel load translations every request?

[WokoLiu]

When I use flask_babel.gettext function, I found that it would walk all the BABEL_TRANSLATION_DIRECTORIES to find and load locate&translations every request.

Is it necessary? Why we do this? Maybe we can load all the .mo file before every real request?

Or do I use it wrong?

Here is my localeselector.

from flask import request

@babel.localeselector
    def get_locale():
        return request.accept_languages.best

Please tell me I'm wrong... Thanks

I've been tracking through the code and came to the same conclusion (I doubted myself as it's seems pretty odd). It's this function:

def _get_current_context():
    if has_request_context():
        return request

    if current_app:
        return current_app

which could be optimised. Unfortunately it's a global function, i.e. not in the Babel class, so is hard to override :-(

The forked Flask-BabelEx project cites this as the reason for it to exist. Unfortunately it doesn't seem as well maintained.

Resolved in v2.0.0, pending release.

This is great in production, but is there a way to get the previous behavior in debug mode, for example?
