- Renaming default credentials -> google default credentials.
- Various other things in cpp:
- Adding Cpp wrapping for JWT Tokens.
- Renaming ComposeCredentials -> CompositeCredentials.
- Tested with new tool (print_default_creds_token) on:
- workstation for env var and well known place.
- GCE for compute engine default creds.
- I'd prefer the grpc_default_credentials_create() API to remain
synchronous even though there may be an async call for gce detection
on which we block.
We now pass down pointers to closures instead of (callback, arg) pair
elements separately. This allows us to store one word atomically, fixing
a race condition.
All call sites have been updated to the new API. No new allocations are
incurred. grpc_fd_state is deleted to avoid any temptation to ever add
anything there again.
Allow binding a different completion queue to each registered method.
This will allow multiplexing for the C++ server between sync & async
methods more easily.
This is a multipoller based on epoll rather than poll.
Note that this implementation is aimed at correctness rather than
performance, although it should immediately have better scalability to
large numbers of FDs, both due to epoll's O(1) sized API and due to not
needing to wake up polling threads to do interest set changes.
One notable difference here is that we directly attach a wakeup fd
rather than using the freelisting kick mechanism that the poll() based
implementations use, because modifying the epoll set to use a different
kick fd each time isn't free.
- Fixes#405.
- This change is not tested as it should (only end to end and no
negative testing). Will do better when we have testing framework
for filters.
