- Had to chnage the core API to add a destroy function pointer in
grpc_auth_metadata_processor.
- Tested end to end.
- Fixed some issues in the server_auth_filter (we were not checking the
length which put us at risk of an overflow).
- Removing service_accounts credentials. These credentials just have
drawbacks compared to service_account_jwt_access credentials, notably
in terms for security.
- Renaming Google specific credentials with a Google prefix for C and
C++. This should be done as well for wrapped languages.
Rephrase API's such that resolvers are constrained to be able to provide a
default host given just the text of the URI channel target.
This avoids needing to rewrite such details in the core library during
retries, and generally makes things much saner to debug.
- Positive tests pass even if we will have to change the interface to
add the processor to the server credentials (will be done in a
separate pull request).
- ASAN leaks for the error case.
- The client should get a GRPC_STATUS_UNAUTHENTICATED as opposed to
GPRC_STATUS_INTERNAL.
- Right now it is a global function: would be better to have this per
(secure) port.
- Changed the interface of the auth_context slightly to make it more
friendly.
- Positive tests pass. Still need some work on error case (have a
negative case as well).
- Fixing cpp auth context tests so that they use the shiny new C API.
