+# Overview
+
+gRPC-Web provides a JS client library that supports the same API
+as gRPC-Node to access a gRPC service. Due to browser limitation,
+the Web client library implements a different protocol than the
+[native gRPC protocol](http://www.grpc.io/docs/guides/wire.html).
+This protocol is designed to make it easy for a proxy to translate
+between the protocols as this is the most likely deployment model.
+
+This document lists the differences between the two protocols.
+To help tracking future revisions, this document describes a delta
+with the protocol details specified in the
+[native gRPC protocol](http://www.grpc.io/docs/guides/wire.html).
+
+# Design goals
+
+For the gRPC-Web protocol, we have decided on the following design goals:
+
+* adopt the same framing as “application/grpc� whenever possible
+* decouple from HTTP/2 framing which is not, and will never, be directly
+exposed by browsers
+* support text streams (e.g. base64) in order to provide cross-browser
+support (e.g. IE-10)
+
+While the new protocol will be published/reviewed publicly, we also
+intend to keep the protocol as an internal detail to gRPC-Web.
+More specifically, we expect the protocol to
+
+* evolve over time, mainly to optimize for browser clients or support
+web-specific features such as CORS, XSRF
+* become optional (in 1-2 years) when browsers are able to speak the native
+gRPC protocol via the new [whatwg fetch/streams API](https://github.com/whatwg/fetch)
+
+# Protocol differences vs [gRPC over HTTP2](http://www.grpc.io/docs/guides/wire.html)
+
+Content-Type
+
+1. application/grpc-web
+  * e.g. application/grpc-web+[proto, json, thrift]
+2. application/grpc-web-text
+  * text-encoded streams of “application/grpc-web�
+
+---
+
+HTTP wire protocols
+
+1. support any HTTP/*, with no dependency on HTTP/2 specific framing
+2. use lower-case header/trailer names
+3. use EOF (end of body) to close the stream
+
+---
+
+HTTP/2 related behavior (specified in [gRPC over HTTP2](http://www.grpc.io/docs/guides/wire.html))
+
+1. stream-id is not supported or used
+2. go-away is not supported or used
+
+---
+
+Message framing (vs. [http2-transport-mapping](http://www.grpc.io/docs/guides/wire.html#http2-transport-mapping))
+
+1. Response status encoded as part of the response body
+  * Key-value pairs encoded in the HTTP/2 [literal header format](https://tools.ietf.org/html/rfc7541#section-6.2) as a single header block.
+2. 8th (MSB) bit of the 1st gRPC frame byte
+  * 0: data
+  * 1: trailers
+3. Trailers must be the last message of the response, as enforced
+by the implementation
+4. Trailers-only responses: no change to the gRPC protocol spec.
+Trailers will be sent together with response headers, with no message
+in the body.
+
+---
+
+User Agent
+
+* grpc-web-javascript/0.1
+
+---
+
+Text-encoded (response) streams
+
+1. The client library should indicate to the server via the "Accept" header that
+the response stream needs to be text encoded e.g. when XHR is used or due
+to security policies with XHR
+  * Accept: application/grpc-web-text
+2. The default text encoding is base64
+  * Text encoding may be specified with Content-Type or Accept headers as
+      * application/grpc-web-text-base64
+  * Note that “Content-Transfer-Encoding: base64� should not be used.
+  Due to in-stream base64 padding when delimiting messages, the entire
+  response body is not necessarily a valid base64-encoded entity
+  * While the server runtime will always base64-encode and flush gRPC messages
+  atomically the client library should not assume base64 padding always
+  happens at the boundary of message frames.
+3. For binary trailers, when the content-type is set to
+application/grpc-web-text, the extra base64 encoding specified
+in [gRPC over HTTP2](http://www.grpc.io/docs/guides/wire.html)
+for binary custom metadata is skipped.
+
+# Other features
+
+Compression
+
+* Full-body compression is supported and expected for all unary
+requests/responses. The compression/decompression will be done
+by browsers, using standard Content-Encoding headers
+  * “grpc-encoding� header is not used
+  * SDCH, Brotli will be supported
+* Message-level compression for streamed requests/responses is not supported
+because manual compression/decompression is prohibitively expensive using JS
+  * Per-message compression may be feasible in future with wasm
+
+---
+
+Retries, caching
+
+* Will spec out the support after their respective gRPC spec extensions
+are finalized
+  * Safe retries: PUT
+  * Caching: header encoded request and/or a web specific spec
+
+---
+
+Security
+
+* XSRF, XSS etc to be specified
+
+---
+
+CORS preflight
+
+* The client library may support header overwrites to avoid preflight
+  * https://github.com/whatwg/fetch/issues/210
+* CSP support to be specified
+
+---
+
+Keep-alive
+
+* HTTP/2 PING is not supported or used
+* Will not support send-beacon (GET)
+
+---
+
+Bidi-streaming, with flow-control
+
+* Pending on [whatwg fetch/streams](https://github.com/whatwg/fetch) to be
+finalized and implemented in modern browsers
+* gRPC-Web client will support the native gRPC protocol with modern browsers

-<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`.

+Negative HTTP/2 Interop Test Case Descriptions
+=======================================
+
+Client and server use
+[test.proto](../src/proto/grpc/testing/test.proto).
+
+Server
+------
+The code for the custom http2 server can be found
+[here](https://github.com/grpc/grpc/tree/master/test/http2_test).
+It is responsible for handling requests and sending responses, and also for 
+fulfilling the behavior of each particular test case.
+
+Server should accept these arguments:
+* --port=PORT
+  * The port the server will run on. For example, "8080"
+* --test_case=TESTCASE
+  * The name of the test case to execute. For example, "goaway"
+
+Client
+------
+
+Clients implement test cases that test certain functionality. Each client is
+provided the test case it is expected to run as a command-line parameter. Names
+should be lowercase and without spaces.
+
+Clients should accept these arguments:
+* --server_host=HOSTNAME
+    * The server host to connect to. For example, "localhost" or "127.0.0.1"
+* --server_port=PORT
+    * The server port to connect to. For example, "8080"
+* --test_case=TESTCASE
+    * The name of the test case to execute. For example, "goaway"
+
+Note
+-----
+
+Note that the server and client must be invoked with the same test case or else
+the test will be meaningless. For convenience, we provide a shell script wrapper
+that invokes both server and client at the same time, with the same test_case.
+This is the preferred way to run these tests.
+
+## Test Cases
+
+### goaway
+
+This test verifies that the client correctly responds to a goaway sent by the
+server. The client should handle the goaway by switching to a new stream without
+the user application having to do a thing.
+
+Client Procedure:
+ 1. Client sends two UnaryCall requests with:
+ 
+    ```
+    {
+      response_size: 314159
+      payload:{
+        body: 271828 bytes of zeros
+      }
+    }
+    ```
+
+Client asserts:
+* Call was successful.
+* Response payload body is 314159 bytes in size.
+
+Server Procedure:
+  1. Server sends a GOAWAY after receiving the first UnaryCall.
+
+Server asserts:
+* The second UnaryCall has a different stream_id than the first one.
+
+### rst_after_header
+
+This test verifies that the client fails correctly when the server sends a
+RST_STREAM immediately after sending headers to the client.
+
+Procedure:
+ 1. Client sends UnaryCall with:
+ 
+    ```
+    {
+      response_size: 314159
+      payload:{
+        body: 271828 bytes of zeros
+      }
+    }
+    ```
+
+Client asserts:
+* Call was not successful.
+
+Server Procedure:
+  1. Server sends a RST_STREAM with error code 0 after sending headers to the client.
+  
+*At the moment the error code and message returned are not standardized throughout all
+languages. Those checks will be added once all client languages behave the same way. [#9142](https://github.com/grpc/grpc/issues/9142) is in flight.*
+
+### rst_during_data
+
+This test verifies that the client fails "correctly" when the server sends a
+RST_STREAM halfway through sending data to the client.
+
+Procedure:
+ 1. Client sends UnaryCall with:
+ 
+    ```
+    {
+      response_size: 314159
+      payload:{
+        body: 271828 bytes of zeros
+      }
+    }
+    ```
+
+Client asserts:
+* Call was not successful.
+
+Server Procedure:
+  1. Server sends a RST_STREAM with error code 0 after sending half of 
+     the requested data to the client.
+
+### rst_after_data
+
+This test verifies that the client fails "correctly" when the server sends a
+RST_STREAM after sending all of the data to the client.
+
+Procedure:
+ 1. Client sends UnaryCall with:
+ 
+    ```
+    {
+      response_size: 314159
+      payload:{
+        body: 271828 bytes of zeros
+      }
+    }
+    ```
+
+Client asserts:
+* Call was not successful.
+
+Server Procedure:
+  1. Server sends a RST_STREAM with error code 0 after sending all of the
+  data to the client.
+
+*Certain client languages allow the data to be accessed even though a RST_STREAM
+was encountered. Once all client languages behave this way, checks will be added on
+the incoming data.*
+
+### ping
+
+This test verifies that the client correctly acknowledges all pings it gets from the
+server.
+
+Procedure:
+ 1. Client sends UnaryCall with:
+ 
+    ```
+    {
+      response_size: 314159
+      payload:{
+        body: 271828 bytes of zeros
+      }
+    }
+    ```
+  
+Client asserts:
+* call was successful.
+* response payload body is 314159 bytes in size.
+
+Server Procedure:
+  1. Server tracks the number of outstanding pings (i.e. +1 when it sends a ping, and -1 
+  when it receives an ack from the client).
+  2. Server sends pings before and after sending headers, also before and after sending data.
+  
+Server Asserts:
+* Number of outstanding pings is 0 when the connection is lost.
+
+### max_streams
+
+This test verifies that the client observes the MAX_CONCURRENT_STREAMS limit set by the server.
+
+Client Procedure:
+  1. Client sends initial UnaryCall to allow the server to update its MAX_CONCURRENT_STREAMS settings.
+  2. Client concurrently sends 10 UnaryCalls.
+  
+Client Asserts:
+* All UnaryCalls were successful, and had the correct type and payload size.
+ 
+Server Procedure:
+  1. Sets MAX_CONCURRENT_STREAMS to one after the connection is made.
+
+*The assertion that the MAX_CONCURRENT_STREAMS limit is upheld occurs in the http2 library we used.*

+# Stress Test framework for gRPC
+
+(Sree Kuchibhotla - sreek@)
+
+> Status: This is implemented. More details at [README.md](https://github.com/grpc/grpc/blob/master/tools/run_tests/stress_test/README.md)
+
+
+**I. GOALS**
+
+1) Build a stress test suite for gRPC:
+
+* Build a stress test suite that can Identify bugs by testing the system (gRPC server/client) under extreme conditions:
+  * High load
+  * High concurrency
+  * Limited resources 
+  * Intermittent failures
+* Should be integrated with Jenkins CI
+
+2) Make it generic enough (i.e build a generic test framework) that can be used for:
+
+* Executing M instances of a client against N instances of a server with an arbitrarily defined connection matrix
+   * Execute heterogenous test configurations - for example: Java stress test clients against C++ servers or Node clients against Python servers or TSAN C++ clients vs ASAN C++ Servers etc.
+   * Easy and Flexible enough that Devs can use it to recreate complex test scenarios
+
+The implementation effort is divided into two parts:
+
+* Building a "Stress Test Framework" to run the stress test suites- More details in **Section II** (The idea is that the Stress Test framework is generic enough that it would be easier to modify it to run other suites like interop-tests or custom test scenarios)
+* Building a 'Stress test suite' - More details in **section III**
+
+**Terminology:**
+
+GCE - Google compute engine
+GKE - Google Container engine
+Kubernetes - Google's open source service scheduler / orchestrator.
+
+**Note:** The terms GKE and Kubernetes are used interchangeably in this document
+
+# II. STRESS TEST FRAMEWORK
+
+(The details of each step are explained below))
+![image](images/stress_test_framework.png)
+**Figure 1**
+
+### Step 1 Read the test config, generate base docker images
+
+**_Test Config:_** The test configuration contains the following information:
+
+* _GKE info:_ GKE project and cluster info
+* _Docker images:_ Instructions to build docker images
+* _Client templates:_ One or more client templates each containing the following information:
+    * Which docker image to use
+    * Path to the client program to launch (within the docker image)
+    * Parameters to the client program
+* _Server templates:_ Similar to Client templates - except that these are for servers
+* Test matrix containing the following:
+    * _Server groups:_ One or more groups of servers containing the following info for each group
+        * Which server template to use
+        * How many instances to launch
+    * _Client groups:_ One or more groups of clients containing the following (for each group):
+        * Which client template to use
+        * How many instances to launch
+        * Which server group to talk to (all clients in this group will talk to all servers in the server group)
+
+The first step is to read the test config and build the docker images
+
+**_Stress server docker image:_** The following are the main files in the server docker images
+
+* _Interop_server:_ The server program
+* `run_server.py`: This is a python script which is the entry point of the docker image (i.e this is the script that is called when the docker image is run in GKE).  This script launches the interop server and also updates the status in BigQuery.  If the interop_server fails for whatever reason, the script launch_server.py logs that status in BigQuery
+
+**_Stress client docker image:_**
+
+* Stress client: The stress test client.  In addition to talking to the interop_server, the stress client also exports metrics (which can be queried by the metrics_client described below)
+* Metrics client: Metrics client connects to the stress_client to get the current qps metrics.
+* `run_client.py`: This is a python script which is the entry point of the docker image (i.e this is the script that is called when the docker image is run in GKE). This script launches the stress client and also updates the status in BigQuery.  The script then periodically launches metrics client to query the qps from the stress client and then uploads the qps to BigQuery.
+
+### Step 2) Upload the docker images to GKE
+The docker images are uploaded to the GKE registry
+
+### Step 3) Launch the tests in GKE
+The test driver reads the test matrix (described in step 1) and creates the necessary server and client pods in GKE.
+
+### Step 4) Tests are run in GKE
+GKE starts running the tests by calling the entry points in *each* docker image (i.e `run_server.py` or `run_client.py` depending on whcih docker image it is)
+
+### Step 5) Upload the status to GKE and Monitor the status in GKE
+* 5.1 The tests periodically update their status in BigQuery
+* 5.2 The test driver periodically checks the status in Bigquery to see if any tests failed.  If any tests failed, the driver immediately stops the tests.  If not, the driver continues to run the tests for a configurable amount of time.
+
+### Step 6) Create a summary report
+The test driver creates a final summary report containing details about any test failures and information about how to connect the failed pods in GKE for debugging.

+/** \file Tracks resource usage against a pool.
+
+    The current implementation tracks only memory usage, but in the future
+    this may be extended to (for example) threads and file descriptors.
+
+    A grpc_resource_quota represents the pooled resources, and
+    grpc_resource_user instances attach to the quota and consume those
+    resources. They also offer a vector for reclamation: if we become
+    resource constrained, grpc_resource_user instances are asked (in turn) to
+    free up whatever they can so that the system as a whole can make progress.
+
+    There are three kinds of reclamation that take place, in order of increasing
+    invasiveness:
+    - an internal reclamation, where cached resource at the resource user level
+      is returned to the quota
+    - a benign reclamation phase, whereby resources that are in use but are not
+      helping anything make progress are reclaimed
+    - a destructive reclamation, whereby resources that are helping something
+      make progress may be enacted so that at least one part of the system can
+      complete.
+
+    Only one reclamation will be outstanding for a given quota at a given time.
+    On each reclamation attempt, the kinds of reclamation are tried in order of
+    increasing invasiveness, stopping at the first one that succeeds. Thus, on a
+    given reclamation attempt, if internal and benign reclamation both fail, it
+    will wind up doing a destructive reclamation. However, the next reclamation
+    attempt may then be able to get what it needs via internal or benign
+    reclamation, due to resources that may have been freed up by the destructive
+    reclamation in the previous attempt.
+
+    Future work will be to expose the current resource pressure so that back
+    pressure can be applied to avoid reclamation phases starting.
+
+    Resource users own references to resource quotas, and resource quotas
+    maintain lists of users (which users arrange to leave before they are
+    destroyed) */

+#Internal continuous integration
+
+gRPC's externally facing testing is managed by Jenkins CI (see `tools/jenkins`
+directory). Nevertheless, some of the tests are better suited for being run
+on internal infrastructure and using an internal CI system. Configuration for
+such tests is under this directory.
