 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
+The majority of gRPC's C++ requirements are drawn from the [Google C++ style
+guide] (https://google.github.io/styleguide/cppguide.html). Additionally,
+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`.

+/** \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) */
