- Add shutdown() method (to be used in forthcoming call combiner code).
- Use a vtable instead of storing method pointers in each instance.
- Check all callers of pull() to make sure that they are properly
handling errors.
- Clarify ownership rules and attempt to adhere to them.
- Added a new grpc_caching_byte_stream implementation, which is used in
http_client_filter to avoid having to read the whole send_message byte
stream before passing control down the stack. (This class may also be
used in the retry code I'm working on separately.)
- As part of this, did a major rewrite of http_client_filter, which
made the code more readable and fixed a number of potential bugs.
Note that some of this code is hard to test right now, due to the fact
that the send_message byte stream is always a slice_buffer stream, for
which next() is always synchronous and no destruction is needed.
However, some future work (specifically, my call combiner work and
Craig's incremental send work) will start leveraging this.
- When receiving a Trailers-Only response, return the metadata as
trailing metadata instead of initial metadata.
- Send Trailers-Only response when we have no non-default initial metadata,
no message to send, and trailing metadata to send.
- trace system is now thread safe when run with TSAN
- fix a race in client_auth_filter.c
- allow timer manager to run in single threaded mode for fuzzers
- make closures know where they should be executed (eg, on a workqueue,
or a combiner, or on an exec_ctx)
- this allows removal of a large number of trampoline functions that
were appearing whenever we used combiners, and should allow for a much
easier interface to combiner locks
