streams: Stop cleaning up after orphaned streams (#1854) 
This change introduces some behavior changes that should not impact users that
are following the proper stream protocol. Specifically, one of the following
conditions must be satisfied:

1. The user calls Close on the ClientConn.
2. The user cancels the context provided to NewClientStream, or its deadline
    expires. (Note that it if the context is no longer needed before the deadline
    expires, it is still recommended to call cancel to prevent bloat.) It is always
    recommended to cancel contexts when they are no longer needed, and to
    never use the background context directly, so all users should always be
    doing this.
3. The user calls RecvMsg (or Recv in generated code) until a non-nil error is
    returned.
4. The user receives any error from Header or SendMsg (or Send in generated
    code) besides io.EOF.  If none of the above happen, this will leak a goroutine
    and a context, and grpc will not call the optionally-configured stats handler
    with a stats.End message.

Before this change, if a user created a stream and the server ended the stream,
the stats handler would be invoked with a stats.End containing the final status
of the stream. Subsequent calls to RecvMsg would then trigger the stats handler
with InPayloads, which may be unexpected by stats handlers.

Menghan Li 41d9b6ea2a Do not flush NewStream header on client side for unary RPCs and streaming RPCs with requests. (#1343) 
If it's not client streaming, we should already have the request to be sent,
so we don't flush the header.
If it's client streaming, the user may never send a request or send it any
time soon, so we ask the transport to flush the header.

And flush header even without metadata

dfawley b507112439 Add status package for reporting gRPC status and errors (#1156) 
When an error implemented by the status package is returned from a service
handler, the server will transmit a rich status message in the
"grpc-status-details-bin" trailing metadata field if any detailed data is
attached to the error.  Client-side, we will decode them if present in the
server's response and return them to the user code performing the RPC.

This is backward compatible with the existing errors supported by the grpc
package.  However, the grpc.Errorf, grpc.Code and grpc.ErrorDesc functions for
managing errors are now deprecated; status.Errorf and status.Status type
asserions should be used instead.

Fix crashes where transports returned errors unhandled by the message parser
 2016-02-24 18:22:25 -08:00
Brad Fitzpatrick 110fd99e30 Fix crashes where transports returned errors unhandled by the message parser. 
The http.Handler-based transport body reader was returning error types
not understood by the recvMsg parser. See #557 for some background and
examples.

Fix the http.Handler transport and add tests. I copied in a subset of
the http2 package's serverTest type, adapted slightly to work with
grpc. In the process of adding tests, I discovered that
ErrUnexpectedEOF was also not handled by the regular server
transport. Document the rules and fix that crash as well.

Unrelated stuff in this CL:

* make tests listen on localhost:0 instead of :0, to avoid Mac firewall
  pop-up dialogs.

* rename parser.s field to parser.r, to be more idiomatic that it's an
  io.Reader and not anything fancier. (it's not acting like type
  stream, even if that's the typical concrete type)

* move 5 byte temp buffer into parser, rather than allocating it for
  each new message. (drop in the bucket improvement in garbage; more
  to do later)

* rename http2RSTErrConvTab to http2ErrConvTab, per Qi's earlier
  CL. Also add the HTTP/1.1-required error mapping for completeness,
  not that it should ever arise with gRPC, also per Qi's earlier CL
  referenced in #557.

grpc: make trace.FromContext work, and record handler status in traces
 2015-09-28 23:29:59 -07:00
iamqizhao ec99a32572 redesign the API 2015-09-25 13:21:25 -07:00
Sameer Ajmani ee98c48bb4 Incorporate dsymonds' comments. 
Fix another bug: cancel the Context provided to an RPC server handler
as soon as that handler returns, so that goroutines started by that
handler can detect that the handler is done and exit. Without this
fix, goroutines started by a handler will keep running, unless the
handler itself arranges to cancel the context.

iamqizhao 9afcd0c697 preliminary refactoring for custom naming and load balancing 2015-09-23 19:09:37 -07:00
Sameer Ajmani b6c9c5a70f grpc: record the description of the status returned by server RPC 
handlers in request traces, and mark the trace as an error if the
status is not OK.

Install the trace into the Context passed to server handlers using
trace.NewContext, so that code in the server handlers can annotate the
trace using trace.FromContext.
