+# gRPC command line tool
+
+## Overview
+
+This document describes the command line tool that comes with gRPC repository. It is desireable to have command line
+tools written in other languages to roughly follow the same syntax and flags.
+
+At this point, the tool needs to be built from source, and it should be moved out to grpc-tools repository as a stand
+alone application once it is mature enough.
+
+## Core functionality
+
+The command line tool can do the following things:
+
+- Send unary rpc.
+- Attach metadata and display received metadata.
+- Handle common authentication to server.
+- Find the request/response types from a given proto file.
+- Read proto request in text form.
+- Read request in wire form (for protobuf messages, this means serialized binary form).
+- Display proto response in text form.
+- Write response in wire form to a file.
+
+The command line tool should support the following things:
+
+- List server services and methods through server reflection.
+- Infer request/response types from server reflection result.
+- Fine-grained auth control (such as, use this oauth token to talk to the server).
+- Send streaming rpc.
+
+## Code location
+
+To use the tool, you need to get the grpc repository and in the grpc directory execute
+
+```
+$ make grpc_cli
+```
+
+The main file can be found at
+https://github.com/grpc/grpc/blob/master/test/cpp/util/grpc_cli.cc
+
+## Usage
+
+### Basic usage
+
+Send a rpc to a helloworld server at `localhost:50051`:
+
+```
+$ bins/opt/grpc_cli call localhost:50051 SayHello examples/protos/helloworld.proto \
+    "name: 'world'"  --enable_ssl=false
+```
+
+On success, the tool will print out
+
+```
+Rpc succeeded with OK status
+Response: 
+ message: "Hello world"
+```
+
+The `localhost:50051` part indicates the server you are connecting to. `SayHello` is (part of) the
+gRPC method string. Then there is the path to the proto file containing the service definition,
+if it is not under current directory, you can use `--proto_path` to specify a new search root.
+`"name: 'world'"` is the text format of the request proto message. 
+We are not using ssl here by `--enable_ssl=false`. For information on more
+flags, look at the comments of `grpc_cli.cc`.
+
+### Send non-proto rpc
+
+For using gRPC with protocols other than probobuf, you will need the exact method name string
+and a file containing the raw bytes to be sent on the wire
+
+```
+$ bins/opt/grpc_cli call localhost:50051 /helloworld.Greeter/SayHello --input_binary_file=input.bin \
+    --output_binary_file=output.bin
+```
+On success, you will need to read or decode the response from the `output.bin` file.

+Compression is used to reduce the amount of bandwidth used between peers. The
+compression supported by gRPC acts _at the individual message level_, taking
+_message_ [as defined in the wire format
+document](PROTOCOL-HTTP2.md).
+
+The implementation supports different compression algorithms. A _default
+compression level_, to be used in the absence of message-specific settings, MAY
+be specified for during channel creation.
+
+The ability to control compression settings per call and to enable/disable
+compression on a per message basis MAY be used to prevent CRIME/BEAST attacks.
+It also allows for asymmetric compression communication, whereby a response MAY
+be compressed differently, if at all.
+
+### Specification
+
+Compression MAY be configured by the Client Application by calling the
+appropriate API method. There are two scenarios where compression MAY be
+configured:
+
++  At channel creation time, which sets the channel default compression and
+   therefore the compression that SHALL be used in the absence of per-RPC
+   compression configuration.
++  At response time, via:
+   +  For unary RPCs, the {Client,Server}Context instance. 
+   +  For streaming RPCs, the {Client,Server}Writer instance. In this case,
+      configuration is reduced to disabling compression altogether.
+
+### Compression Method Asymmetry Between Peers
+
+A gRPC peer MAY choose to respond using a different compression method to that
+of the request, including not performing any compression, regardless of channel
+and RPC settings (for example, if compression would result in small or negative
+gains).
+
+When a message from a client compressed with an unsupported algorithm is
+processed by a server, it WILL result in an `UNIMPLEMENTED` error status on the
+server. The server will then include in its response a `grpc-accept-encoding`
+header specifying the algorithms it does accept. If an `UNIMPLEMENTED` error
+status is returned from the server despite having used one of the algorithms
+from the `grpc-accept-encoding` header, the cause MUST NOT be related to
+compression. Data sent from a server compressed with an algorithm not supported
+by the client WILL result in an `INTERNAL` error status on the client side.
+
+Note that a peer MAY choose to not disclose all the encodings it supports.
+However, if it receives a message compressed in an undisclosed but supported
+encoding, it MUST include said encoding in the response's `grpc-accept-encoding
+h`eader.
+
+For every message a server is requested to compress using an algorithm it knows
+the client doesn't support (as indicated by the last `grpc-accept-encoding`
+header received from the client), it SHALL send the message uncompressed. 
+
+### Specific Disabling of Compression
+
+If the user (through the previously described mechanisms) requests to disable
+compression the next message MUST be sent uncompressed. This is instrumental in
+preventing BEAST/CRIME attacks. This applies to both the the unary and streaming
+cases.
+
+### Compression Levels and Algorithms
+
+The set of supported algorithm is implementation dependent. In order to simplify
+the public API and to operate seamlessly across implementations (both in terms
+of languages but also different version of the same one), we introduce the idea
+of _compression levels_ (such as "low", "medium", "high").
+
+Levels map to concrete algorithms and/or their settings (such as "low" mapping
+to "gzip -3" and "high" mapping to "gzip -9") automatically depending on what a
+peer is known to support. A server is always aware of what its clients support,
+as clients disclose it in their Message-Accept-Encoding header as part of their
+initial call. A client doesn't a priori (presently) know which algorithms a
+server supports. This issue can be addressed with an initial negotiation of
+capabilities or an automatic retry mechanism. These features will be implemented
+in the future. Currently however, compression levels are only supported at the
+server side, which is aware of the client's capabilities through the incoming
+Message-Accept-Encoding header.
+
+### Propagation to child RPCs
+
+The inheritance of the compression configuration by child RPCs is left up to the
+implementation. Note that in the absence of changes to the parent channel, its
+configuration will be used.
+
+### Test cases
+
+1. When a compression level is not specified for either the channel or the
+message, the default channel level _none_ is considered: data MUST NOT be
+compressed.
+1. When per-RPC compression configuration isn't present for a message, the
+channel compression configuration MUST be used.
+1. When a compression method (including no compression) is specified for an
+outgoing message, the message MUST be compressed accordingly.
+1. A message compressed by a client in a way not supported by its server MUST
+fail with status `UNIMPLEMENTED`, its associated description indicating the
+unsupported condition as well as the supported ones. The returned
+`grpc-accept-encoding` header MUST NOT contain the compression method
+(encoding) used.
+1. A message compressed by a server in a way not supported by its client MUST
+fail with status `INTERNAL`, its associated description indicating the
+unsupported condition as well as the supported ones. The returned
+`grpc-accept-encoding` header MUST NOT contain the compression method
+(encoding) used.
+1. An ill-constructed message with its [Compressed-Flag
+bit](PROTOCOL-HTTP2.md#compressed-flag)
+set but lacking a
+"[grpc-encoding](PROTOCOL-HTTP2.md#message-encoding)"
+entry different from _identity_ in its metadata MUST fail with `INTERNAL`
+status, its associated description indicating the invalid Compressed-Flag
+condition.

+GRPC C++ STYLE GUIDE
+=====================
+
+Background
+----------
+
+Here we document style rules for C++ usage in the gRPC C++ bindings
+and tests.
+
+General
+-------
+
+- The majority of gRPC's C++ requirements are drawn from the [Google C++ style
+guide] (https://google.github.io/styleguide/cppguide.html)
+   - However, gRPC has some additional requirements to maintain
+     [portability] (#portability)
+- As in C, layout rules are defined by clang-format, and all code
+should be passed through clang-format. A (docker-based) script to do
+so is included in [tools/distrib/clang\_format\_code.sh]
+(../tools/distrib/clang_format_code.sh).
+
+<a name="portability"></a>
+Portability Restrictions
+-------------------
+
+gRPC supports a large number of compilers, ranging from those that are
+missing many key C++11 features to those that have quite detailed
+analysis. As a result, gRPC compiles with a high level of warnings and
+treat all warnings as errors. gRPC also forbids the use of some common
+C++11 constructs. Here are some guidelines, to be extended as needed:
+- Do not use range-based for. Expressions of the form
+  ```c
+  for (auto& i: vec) {
+    // code
+  }
+  ```
+  
+  are not allowed and should be replaced with code such as
+  ```c
+  for (auto it = vec.begin; it != vec.end(); it++) {
+    auto& i = *it;
+    // code
+  }
+  ```
+  
+- Do not use lambda of any kind (no capture, explicit capture, or
+default capture). Other C++ functional features such as
+`std::function` or `std::bind` are allowed
+- Do not use brace-list initializers.
+- Do not compare a pointer to `nullptr` . This is because gcc 4.4
+  does not support `nullptr` directly and gRPC implements a subset of
+  its features in [include/grpc++/impl/codegen/config.h]
+  (../include/grpc++/impl/codegen/config.h). Instead, pointers should
+  be checked for validity using their implicit conversion to `bool`.
+  In other words, use `if (p)` rather than `if (p != nullptr)`
+- Do not initialize global/static pointer variables to `nullptr`. Just let
+  the compiler implicitly initialize them to `nullptr` (which it will
+  definitely do). The reason is that `nullptr` is an actual object in
+  our implementation rather than just a constant pointer value, so
+  static/global constructors will be called in a potentially
+  undesirable sequence.
+- Do not use `final` or `override` as these are not supported by some
+  compilers. Instead use `GRPC_FINAL` and `GRPC_OVERRIDE` . These
+  compile down to the traditional C++ forms for compilers that support
+  them but are just elided if the compiler does not support those features.
+- In the [include] (../../../tree/master/include/grpc++) and [src]
+  (../../../tree/master/src/cpp) directory trees, you should also not
+  use certain STL objects like `std::mutex`, `std::lock_guard`,
+  `std::unique_lock`, `std::nullptr`, `std::thread` . Instead, use
+  `grpc::mutex`, `grpc::lock_guard`, etc., which are gRPC
+  implementations of the prominent features of these objects that are
+  not always available. You can use the `std` versions of those in  [test]
+  (../../../tree/master/test/cpp)
+- Similarly, in the same directories, do not use `std::chrono` unless
+  it is guarded by `#ifndef GRPC_CXX0X_NO_CHRONO` . For platforms that
+  lack`std::chrono,` there is a C-language timer called gpr_timespec that can
+  be used instead.
+- `std::unique_ptr` must be used with extreme care in any kind of
+  collection. For example `vector<std::unique_ptr>` does not work in
+  gcc 4.4 if the vector is constructed to its full size at
+  initialization but does work if elements are added to the vector
+  using functions like `push_back`. `map` and other pair-based
+  collections do not work with `unique_ptr` under gcc 4.4. The issue
+  is that many of these collection implementations assume a copy
+  constructor
+  to be available.
+- Don't use `std::this_thread` . Use `gpr_sleep_until` for sleeping a thread.
+- [Some adjacent character combinations cause problems]
+  (https://en.wikipedia.org/wiki/Digraphs_and_trigraphs#C). If declaring a
+  template against some class relative to the global namespace,
+  `<::name` will be non-portable. Separate the `<` from the `:` and use `< ::name`.

+/** Round Robin Policy.
+ *
+ * This policy keeps:
+ * - A circular list of ready (connected) subchannels, the *readylist*. An empty
+ *   readylist consists solely of its root (dummy) node.
+ * - A pointer to the last element picked from the readylist, the *lastpick*.
+ *   Initially set to point to the readylist's root.
+ *
+ * Behavior:
+ * - When a subchannel connects, it's *prepended* to the readylist's root node.
+ *   Ie, if readylist = A <-> B <-> ROOT <-> C
+ *                      ^                    ^
+ *                      |____________________|
+ *   and subchannel D becomes connected, the addition of D to the readylist
+ *   results in  readylist = A <-> B <-> D <-> ROOT <-> C
+ *                           ^                          ^
+ *                           |__________________________|
+ * - When a subchannel disconnects, it's removed from the readylist. If the
+ *   subchannel being removed was the most recently picked, the *lastpick*
+ *   pointer moves to the removed node's previous element. Note that if the
+ *   readylist only had one element, this is still legal, as the lastpick would
+ *   point to the dummy root node, for an empty readylist.
+ * - Upon picking, *lastpick* is updated to point to the returned (connected)
+ *   subchannel. Note that it's possible that the selected subchannel becomes
+ *   disconnected in the interim between the selection and the actual usage of
+ *   the subchannel by the caller.

 Prior to version 0.13, installing `grpc_csharp_ext` was required to make gRPC work on Linux and MacOS. Starting with version 0.13, we have improved the packaging story significantly and precompiled versions of the native library for all supported platforms are now shipped with the NuGet package. Just installing the `Grpc` NuGet package should be the only step needed to use gRPC C#, regardless of your platform (Windows, Linux or Mac) and the bitness (32 or 64bit).

+// Census lets you define a Metric - something which can be measured, like the
+// latency of an RPC, the number of CPU cycles spent on an operation, or
+// anything else you care to measure. You can record individual instances of
+// measurements (a double value) for every metric of interest. These
+// individual measurements are aggregated together into an Aggregation. There
+// are two Aggregation types available: Distribution (describes the
+// distribution of all measurements, possibly with a histogram) and
+// IntervalStats (the count and mean of measurements across specified time
+// periods). An Aggregation is described by an AggregationDescriptor.
+//
+// You can define how your stats are broken down by Tag values and which
+// Aggregations to use through a View. The corresponding combination of
+// Metric/View/Aggregation which is available to census clients is called a
+// ViewAggregation.
+
+
+// The following two types are copied from
+// google/protobuf/{duration,timestamp}.proto. Ideally, we would be able to
+// import them, but this causes compilation issues on C-based systems
+// (e.g. https://koti.kapsi.fi/jpa/nanopb/), which cannot process the C++
+// headers generated from the standard protobuf distribution. See the relevant
+// proto files for full documentation of these types.

 /*
-  A command line tool to talk to any grpc server.
+  A command line tool to talk to a grpc server.
   Example of talking to grpc interop server:
-  1. Prepare request binary file:
-    a. create a text file input.txt, containing the following:
-        response_size: 10
-        payload: {
-          body: "hello world"
-        }
-    b. under grpc/ run
-        protoc --proto_path=src/proto/grpc/testing/ \
-        --encode=grpc.testing.SimpleRequest
-  src/proto/grpc/testing/messages.proto \
-        < input.txt > input.bin
-  2. Start a server
-    make interop_server && bins/opt/interop_server --port=50051
-  3. Run the tool
-    make grpc_cli && bins/opt/grpc_cli call localhost:50051 \
-    /grpc.testing.TestService/UnaryCall --enable_ssl=false \
-    --input_binary_file=input.bin --output_binary_file=output.bin
-  4. Decode response
-    protoc --proto_path=src/proto/grpc/testing/ \
-    --decode=grpc.testing.SimpleResponse src/proto/grpc/testing/messages.proto \
-    < output.bin > output.txt
-  5. Now the text form of response should be in output.txt
-  Optionally, metadata can be passed to server via flag --metadata, e.g.
-    --metadata="MyHeaderKey1:Value1:MyHeaderKey2:Value2"
+  grpc_cli call localhost:50051 UnaryCall src/proto/grpc/testing/test.proto \
+    "response_size:10"  --enable_ssl=false
+
+  Options:
+    1. --proto_path, if your proto file is not under current working directory,
+       use this flag to provide a search root. It should work similar to the
+       counterpart in protoc.
+    2. --metadata specifies metadata to be sent to the server, such as:
+       --metadata="MyHeaderKey1:Value1:MyHeaderKey2:Value2"
+    3. --enable_ssl, whether to use tls.
+    4. --use_auth, if set to true, attach a GoogleDefaultCredentials to the call
+    3. --input_binary_file, a file containing the serialized request. The file
+       can be generated by calling something like:
+       protoc --proto_path=src/proto/grpc/testing/ \
+         --encode=grpc.testing.SimpleRequest \
+         src/proto/grpc/testing/messages.proto \
+         < input.txt > input.bin
+       If this is used and no proto file is provided in the argument list, the
+       method string has to be exact in the form of /package.service/method.
+    4. --output_binary_file, a file to write binary format response into, it can
+       be later decoded using protoc:
+       protoc --proto_path=src/proto/grpc/testing/ \
+       --decode=grpc.testing.SimpleResponse \
+       src/proto/grpc/testing/messages.proto \
+       < output.bin > output.txt
