+Thrift C++ Software Library

+
+Using Thrift with C++
+=====================
+
+The Thrift C++ libraries are built using the GNU tools. Follow the instructions
+in the top-level README, or run bootstrap.sh in this folder to generate the
+Makefiles.
+
+In case you do not want to open another README file, do this:
+  ./bootstrap.sh
+  ./configure (--with-boost=/usr/local)
+  make
+  sudo make install
+
+Thrift is divided into two libraries.
+
+libthrift
+  The core Thrift library contains all the core Thrift code. It requires
+  boost shared pointers, pthreads, and librt.
+
+libthriftnb
+  This library contains the Thrift nonblocking server, which uses libevent.
+  To link this library you will also need to link libevent.
+
+Linking Against Thrift
+======================
+
+After you build and install Thrift the libraries are installed to
+/usr/local/lib by default. Make sure this is in your LDPATH.
+
+On Linux, the best way to do this is to ensure that /usr/local/lib is in
+your /etc/ld.so.conf and then run /sbin/ldconfig.
+
+Depending upon whether you are linking dynamically or statically and how
+your build environment it set up, you may need to include additional
+libraries when linking against thrift, such as librt and/or libpthread. If
+you are using libthriftnb you will also need libevent.
+
+Dependencies
+============
+
+boost shared pointers
+http://www.boost.org/libs/smart_ptr/smart_ptr.htm
+
+libevent (for libthriftnb only)
+http://monkey.org/~provos/libevent/

+
+IMPLEMENTATION DETAILS
+
+TDenseProtocol was designed to have a smaller serialized form than
+TBinaryProtocol.  This is accomplished using two techniques.  The first is
+variable-length integer encoding.  We use the same technique that the Standard
+MIDI File format uses for "variable-length quantities"
+(http://en.wikipedia.org/wiki/Variable-length_quantity).
+All integers (including i16, but not byte) are first cast to uint64_t,
+then written out as variable-length quantities.  This has the unfortunate side
+effect that all negative numbers require 10 bytes, but negative numbers tend
+to be far less common than positive ones.
+
+The second technique eliminating the field ids used by TBinaryProtocol.  This
+decision required support from the Thrift compiler and also sacrifices some of
+the backward and forward compatibility of TBinaryProtocol.
+
+We considered implementing this technique by generating separate readers and
+writers for the dense protocol (this is how Pillar, Thrift's predecessor,
+worked), but this idea had a few problems:
+- Our abstractions go out the window.
+- We would have to maintain a second code generator.
+- Preserving compatibility with old versions of the structures would be a
+  nightmare.
+
+Therefore, we chose an alternate implementation that stored the description of
+the data neither in the data itself (like TBinaryProtocol) nor in the
+serialization code (like Pillar), but instead in a separate data structure,
+called a TypeSpec.  TypeSpecs are generated by the Thrift compiler
+(specifically in the t_cpp_generator), and their structure should be
+documented there (TODO(dreiss): s/should be/is/).
+
+We maintain a stack of TypeSpecs within the protocol so it knows where the
+generated code is in the reading/writing process.  For example, if we are
+writing an i32 contained in a struct bar, contained in a struct foo, then the
+stack would look like: TOP , i32 , struct bar , struct foo , BOTTOM.
+The following invariant: whenever we are about to read/write an object
+(structBegin, containerBegin, or a scalar), the TypeSpec on the top of the
+stack must match the type being read/written.  The main reasons that this
+invariant must be maintained is that if we ever start reading a structure, we
+must have its exact TypeSpec in order to pass the right tags to the
+deserializer.
+
+We use the following strategies for maintaining this invariant:
+
+- For structures, we have a separate stack of indexes, one for each structure
+  on the TypeSpec stack.  These are indexes into the list of fields in the
+  structure's TypeSpec.  When we {read,write}FieldBegin, we push on the
+  TypeSpec for the field.
+- When we begin writing a list or set, we push on the TypeSpec for the
+  element type.
+- For maps, we have a separate stack of booleans, one for each map on the
+  TypeSpec stack.  The boolean is true if we are writing the key for that
+  map, and false if we are writing the value.  Maps are the trickiest case
+  because the generated code does not call any protocol method between
+  the key and the value.  As a result, we potentially have to switch
+  between map key state and map value state after reading/writing any object.
+- This job is handled by the stateTransition method.  It is called after
+  reading/writing every object.  It pops the current TypeSpec off the stack,
+  then optionally pushes a new one on, depending on what the next TypeSpec is.
+  If it is a struct, the job is left to the next writeFieldBegin.  If it is a
+  set or list, the just-popped typespec is pushed back on.  If it is a map,
+  the top of the key/value stack is toggled, and the appropriate TypeSpec
+  is pushed.
+
+Optional fields are a little tricky also.  We write a zero byte if they are
+absent and prefix them with an 0x01 byte if they are present

+ * !!!WARNING!!!
+ * This class is still highly experimental.  Incompatible changes
+ * WILL be made to it without notice.  DO NOT USE IT YET unless
+ * you are coordinating your testing with the author.
+ *
+ * The dense protocol is designed to use as little space as possible.
+ *
+ * There are two types of dense protocol instances.  Standalone instances
+ * are not used for RPC and just encoded and decode structures of
+ * a predetermined type.  Non-standalone instances are used for RPC.
+ * Currently, only standalone instances exist.
+ *
+ * To use a standalone dense protocol object, you must set the type_spec
+ * property (either in the constructor, or with setTypeSpec) to the local
+ * reflection TypeSpec of the structures you will write to (or read from) the
+ * protocol instance.
+ *
+ * BEST PRACTICES:
+ * - Never use optional for primitives or containers.
+ * - Only use optional for structures if they are very big and very rarely set.
+ * - All integers are variable-length, so you can use i64 without bloating.
+ * - NEVER EVER change the struct definitions IN ANY WAY without either
+ *   changing your cache keys or talking to dreiss.
+ *
+ * TODO(dreiss): New class write with old meta.
+ *
+ * We override all of TBinaryProtocol's methods.
+ * We inherit so that we can can explicitly call TBPs's primitive-writing
+ * methods within our versions.

+/**
+ * JSON protocol for Thrift.
+ *
+ * Implements a protocol which uses JSON as the wire-format.
+ *
+ * Thrift types are represented as described below:
+ *
+ * 1. Every Thrift integer type is represented as a JSON number.
+ *
+ * 2. Thrift doubles are represented as JSON numbers. Some special values are
+ *    represented as strings:
+ *    a. "NaN" for not-a-number values
+ *    b. "Infinity" for postive infinity
+ *    c. "-Infinity" for negative infinity
+ *
+ * 3. Thrift string values are emitted as JSON strings, with appropriate
+ *    escaping.
+ *
+ * 4. Thrift binary values are encoded into Base64 and emitted as JSON strings.
+ *    The readBinary() method is written such that it will properly skip if
+ *    called on a Thrift string (although it will decode garbage data).
+ *
+ * 5. Thrift structs are represented as JSON objects, with the field ID as the
+ *    key, and the field value represented as a JSON object with a single
+ *    key-value pair. The key is a short string identifier for that type,
+ *    followed by the value. The valid type identifiers are: "tf" for bool,
+ *    "i8" for byte, "i16" for 16-bit integer, "i32" for 32-bit integer, "i64"
+ *    for 64-bit integer, "dbl" for double-precision loating point, "str" for
+ *    string (including binary), "rec" for struct ("records"), "map" for map,
+ *    "lst" for list, "set" for set.
+ *
+ * 6. Thrift lists and sets are represented as JSON arrays, with the first
+ *    element of the JSON array being the string identifier for the Thrift
+ *    element type and the second element of the JSON array being the count of
+ *    the Thrift elements. The Thrift elements then follow.
+ *
+ * 7. Thrift maps are represented as JSON arrays, with the first two elements
+ *    of the JSON array being the string identifiers for the Thrift key type
+ *    and value type, followed by the count of the Thrift pairs, followed by a
+ *    JSON object containing the key-value pairs. Note that JSON keys can only
+ *    be strings, which means that the key type of the Thrift map should be
+ *    restricted to numeric or string types -- in the case of numerics, they
+ *    are serialized as strings.
+ *
+ * 8. Thrift messages are represented as JSON arrays, with the protocol
+ *    version #, the message name, the message type, and the sequence ID as
+ *    the first 4 elements.
+ *
+ * More discussion of the double handling is probably warranted. The aim of
+ * the current implementation is to match as closely as possible the behavior
+ * of Java's Double.toString(), which has no precision loss.  Implementors in
+ * other languages should strive to achieve that where possible. I have not
+ * yet verified whether boost:lexical_cast, which is doing that work for me in
+ * C++, loses any precision, but I am leaving this as a future improvement. I
+ * may try to provide a C component for this, so that other languages could
+ * bind to the same underlying implementation for maximum consistency.
+ *
+ * Note further that JavaScript itself is not capable of representing
+ * floating point infinities -- presumably when we have a JavaScript Thrift
+ * client, this would mean that infinities get converted to not-a-number in
+ * transmission. I don't know of any work-around for this issue.
