-
-    A grpc_resource_quota represents the pooled resources, and

-
-    There are three kinds of reclamation that take place, in order of increasing

-    - 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

-    - a destructive reclamation, whereby resources that are helping something

-
-    Only one reclamation will be outstanding for a given quota at a given time.

 In the C++ world, there's no universally accepted standard for managing project dependencies.
 Therefore, gRPC supports several major build systems, which should satisfy most users.

 Installing From PyPI
 ~~~~~~~~~~~~~~~~~~~~
-
-If you are installing locally...
-
-::
-
-  $ pip install grpcio
-
-Else system wide (on Ubuntu)...
-
-::
-
-  $ sudo pip install grpcio
-
-If you're on Windows make sure that you installed the :code:`pip.exe` component
-when you installed Python (if not go back and install it!) then invoke:
-
-::
-
-  $ pip.exe install grpcio
-
-Windows users may need to invoke :code:`pip.exe` from a command line ran as
-administrator.
-
-n.b. On Windows and on Mac OS X one *must* have a recent release of :code:`pip`
-to retrieve the proper wheel from PyPI. Be sure to upgrade to the latest

 Installing From Source
 ~~~~~~~~~~~~~~~~~~~~~~
-

-package named :code:`python-dev`).
-
-::
-
-  $ export REPO_ROOT=grpc  # REPO_ROOT can be any directory of your choice

+Building from source requires that you have the Python headers (usually a

+  $ export REPO_ROOT=grpc  # REPO_ROOT can be any directory of your choice 
   $ git clone -b RELEASE_TAG_HERE https://github.com/grpc/grpc $REPO_ROOT
-  $ cd $REPO_ROOT
-  $ git submodule update --init
-
-  # For the next two commands do `sudo pip install` if you get permission-denied errors
-  $ pip install -rrequirements.txt
-  $ GRPC_PYTHON_BUILD_WITH_CYTHON=1 pip install .
-
-You cannot currently install Python from source on Windows. Things might work
-out for you in MSYS2 (follow the Linux instructions), but it isn't officially
-supported at the moment.
-
-Troubleshooting
-~~~~~~~~~~~~~~~
-
-Help, I ...
-
-* **... see a** :code:`pkg_resources.VersionConflict` **when I try to install
-  grpc**
-
-  This is likely because :code:`pip` doesn't own the offending dependency,
-  which in turn is likely because your operating system's package manager owns
-  it. You'll need to force the installation of the dependency:
-
-  :code:`pip install --ignore-installed $OFFENDING_DEPENDENCY`
-
-  For example, if you get an error like the following:
-
-  ::
-
-    Traceback (most recent call last):
-    File "<string>", line 17, in <module>
-     ...
-    File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 509, in find
-      raise VersionConflict(dist, req)
-    pkg_resources.VersionConflict: (six 1.8.0 (/usr/lib/python2.7/dist-packages), Requirement.parse('six>=1.10'))
-
-  You can fix it by doing:
-
-  ::
-
-    sudo pip install --ignore-installed six
-
-* **... see the following error on some platforms**
-
-  ::
-
-    /tmp/pip-build-U8pSsr/cython/Cython/Plex/Scanners.c:4:20: fatal error: Python.h: No such file or directory
-    #include "Python.h"
-                    ^
-    compilation terminated.

-  You can fix it by installing `python-dev` package. i.e
-
-  ::
-
-    sudo apt-get install python-dev
-
+  $ cd $REPO_ROOT 
+  $ git submodule update --init 
+ 
+  # For the next two commands do `sudo pip install` if you get permission-denied errors 
+  $ pip install -rrequirements.txt 
+  $ GRPC_PYTHON_BUILD_WITH_CYTHON=1 pip install . 
+ 
+You cannot currently install Python from source on Windows. Things might work 
+out for you in MSYS2 (follow the Linux instructions), but it isn't officially 
+supported at the moment. 
+ 
+Troubleshooting 
+~~~~~~~~~~~~~~~ 
+ 
+Help, I ... 
+ 
+* **... see a** :code:`pkg_resources.VersionConflict` **when I try to install 
+  grpc** 
+ 
+  This is likely because :code:`pip` doesn't own the offending dependency, 
+  which in turn is likely because your operating system's package manager owns 
+  it. You'll need to force the installation of the dependency: 
+ 
+  :code:`pip install --ignore-installed $OFFENDING_DEPENDENCY` 
+ 
+  For example, if you get an error like the following: 
+ 
+  :: 
+ 
+    Traceback (most recent call last): 
+    File "<string>", line 17, in <module> 
+     ... 
+    File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 509, in find 
+      raise VersionConflict(dist, req) 
+    pkg_resources.VersionConflict: (six 1.8.0 (/usr/lib/python2.7/dist-packages), Requirement.parse('six>=1.10')) 
+ 
+  You can fix it by doing: 
+ 
+  :: 
+ 
+    sudo pip install --ignore-installed six 
+ 
+* **... see the following error on some platforms** 
+ 
+  :: 
+ 
+    /tmp/pip-build-U8pSsr/cython/Cython/Plex/Scanners.c:4:20: fatal error: Python.h: No such file or directory 
+    #include "Python.h" 
+                    ^ 
+    compilation terminated. 
+ 
+  You can fix it by installing `python-dev` package. i.e 
+ 
+  :: 
+ 
+    sudo apt-get install python-dev 
+

-GRPC Python Cython layer
-========================
-
-Package for the GRPC Python Cython layer.
-
-What is Cython?
----------------
-
-Cython is both a superset of the Python language with extensions for dealing
-with C types and a tool that transpiles this superset into C code. It provides
-convenient means of statically typing expressions and of converting Python
-strings to pointers (among other niceties), thus dramatically smoothing the
-Python/C interop by allowing fluid use of APIs in both from the same source.
-See the wonderful `Cython website`_.
-
-Why Cython?
------------
-
-- **Python 2 and 3 support**
-  Cython generated C code has precompiler macros to target both Python 2 and
-  Python 3 C APIs, even while acting as a superset of just the Python 2
-  language (e.g. using ``basestring``).
-- **Significantly less semantic noise**
-  A lot of CPython code is just glue, especially human-error-prone
-  ``Py_INCREF``-ing and ``Py_DECREF``-ing around error handlers and such.
-  Cython takes care of that automagically.
-- **Possible PyPy support**
-  One of the major developments in Cython over the past few years was the
-  addition of support for PyPy. We might soon be able to provide such support
-  ourselves through our use of Cython.
-- **Less Python glue code**
-  There existed several adapter layers in and around the original CPython code
-  to smooth the surface exposed to Python due to how much trouble it was to
-  make such a smooth surface via the CPython API alone. Cython makes writing
-  such a surface incredibly easy, so these adapter layers may be removed.
-
-Implications for Users
-----------------------
-
-Nothing additional will be required for users. PyPI packages will contain
-Cython generated C code and thus not necessitate a Cython installation.
-
-Implications for GRPC Developers
---------------------------------
-
-A typical edit-compile-debug cycle now requires Cython. We install Cython in
-the ``virtualenv`` generated for the Python tests in this repository, so
-initial test runs may take an extra 2+ minutes to complete.  Subsequent test
-runs won't reinstall ``Cython`` (unless required versions change and the
-``virtualenv`` doesn't have installed versions that satisfy the change).

-"""A Future interface.
-
-Python doesn't have a Future interface in its standard library. In the absence
-of such a standard, three separate, incompatible implementations
-(concurrent.futures.Future, ndb.Future, and asyncio.Future) have appeared. This
-interface attempts to be as compatible as possible with
-concurrent.futures.Future. From ndb.Future it adopts a traceback-object accessor
-method.
-
-Unlike the concrete and implemented Future classes listed above, the Future
-class defined in this module is an entirely abstract interface that anyone may
-implement and use.
-
-The one known incompatibility between this interface and the interface of
-concurrent.futures.Future is that this interface defines its own CancelledError
-and TimeoutError exceptions rather than raising the implementation-private
-concurrent.futures._base.CancelledError and the
-built-in-but-only-in-3.3-and-later TimeoutError.
