An unfortunate side effect of #364 is that it broke compatibility for
users on very old API versions because their `refunds` field will come
back as an array.
This adds a compatibility layer that will allow even users on old API
versions to seamlessly upgrade their gem versions.
Our CA bundle has fallen quite out of date since it was last pulled.
This patch updates it and adds a Rake task to make this task more
repeatable.
One thing worth noting is I've switched us over from the Ubuntu bundle
to the Mozilla bundle that's maintained by cURL. The bundle seemed to be
previously extracted by a custom script that I don't really want to
maintain. cURL and Excon both use the Mozilla bundle and it should be a
safe replacement.
As requested in #370, this will allow advanced users to configure a
certificate bundle that is expected to be more up-to-date than what
we've managed to include with the gem.
As discussed previously in #354 and alluded to in #363, this patch
deprecates the `#refund` helpers on `Charge` and `ApplicationFee` in
favor of the resource-centric approach (i.e. `charge.refunds.create`).
We do this for a few reasons:
1. The new approach is far preferred and uses our modern endpoints. It's
also been the mechanism suggested by the documentation for ages now.
2. The old approach is somewhat risky in that a forgotten "s" can lead
to an accidental refund (i.e. `charge.refund` instead of
`charge.refunds`).
Follows up #354. Fixes#363.
This is kind of a weird one because it'll only cause a failure when
serializing a subobject or hash of a `StripeObject`, but it's good
practice to initialize instance variables anyway.
Fixes#360.
Follows up the patch in #351, which I now believe is wrong. The trouble
is that we were mutating the application fee object, when in reality an
application fee refund is actually a completely new resource (see
[creating a refund][create-refund]). This patch edits the original
attempt to cut a new object and updates tests accordingly.
Once again, related to stripe/stripe-php#208.
