question about .mo file caching mechanism #207

Closed 841020 closed 1 year ago

Hi there

I have a question So we all know that .mo will be cached in flask app I just want to know if when we run flask server it caches all .mo files at the beginning? Or is it just when we switch languages then it creates domain objects and caches that .mo file?

I thought caching all mo files at the beginning would minimize IO time

I checked the source code, I found that I misunderstood, it should be that each language will generate a cache in the Doamin object when it is used

In this way, the next time the language is switched, the cache can be obtained through key mapping from the Domain
