Help testing Mime latest (upcoming v2)
Hi everyone,
I have started working on the v2 version of the Mime library, used by Plug and Phoenix. The previous version depended on an external Mime database, which made it complicated for us to handle corner cases and, often times, it was too large.
The new version starts a new database from scratch, which should be faster to compile, faster to run, and use less memory. However, it may be missing important mime types. Therefore, I would like to request the community help in two possible ways:
-
Compare the list of supported extensions with the files you have in priv/static (or assets/static). Are all extensions listed? If not, please send a PR to add unsupported extensions.
-
Use mime master as a dependency in your project and see if anything fails:
{:mime, "~> 2.0", github: "elixir-plug/mime", override: true}
Your feedback is deeply appreciated!

Hey, José
I still think that using an external database is generally a good choice, even if it is something that is only manually updated and may generate a file that can be parsed during compile.
I maintain mime-types-data, and I’m happy to update the code there to generate something that is both smaller and easier to work with but more comprehensive than the ~76 types that I see now. (It’s pretty easy to filter the data so that only items with extensions are included (still probably larger than expected as there are 1,198 extensions known to the complete database and 824 extensions attached to 864 IANA registered types).

There is a mechanism for you to define additional types. I think you will need to define each version as its own mime type.

Thank you! Note the warning is fixed on more recent plug versions.

Thanks for the follow up and don’t worry about this. 
Get better!

Just to be sure: did you force MIME to be recompiled so it picks your changes?
