Subject: [PATCH] Ensure `close` is called on the response body no matter what
|
|
|
|
Another fallout from https://github.com/puma/puma/pull/2809 is that
|
|
in some cases the `res_body.close` wasn't called because some previous code
|
|
raised.
|
|
|
|
For Rails apps it means CurrentAttributes and a few other important
|
|
states aren't reset properly.
|
|
|
|
This is being improved on the Rails side too, but I believe it would
|
|
be good to harden this on the puma side as well.
