// this type. The name must start with a '-'. If the name is longer
// than one letter, it must start with two '-'s.
// * generator: The CodeGenerator which will be called to generate files
// of this type.
// * help_text: Text describing this flag in the --help output.
//
// Some generators accept extra parameters. You can specify this parameter
// on the command-line by placing it before the output directory, separated
// by a colon:
// protoc --foo_out=enable_bar:outdir
// The text before the colon is passed to CodeGenerator::Generate() as the
// "parameter".
void RegisterGenerator(const string& flag_name,

// Enables "plugins". In this mode, if a command-line flag ends with "_out"
// but does not match any registered generator, the compiler will attempt to
// find a "plugin" to implement the generator. Plugins are just executables.
// They should live somewhere in the PATH.
//
// The compiler determines the executable name to search for by concatenating
// exe_name_prefix with the unrecognized flag name, removing "_out". So, for
// example, if exe_name_prefix is "protoc-" and you pass the flag --foo_out,
// the compiler will try to run the program "protoc-foo".
//
// The plugin program should implement the following usage:
// plugin [--out=OUTDIR] [--parameter=PARAMETER] PROTO_FILES < DESCRIPTORS
// --out indicates the output directory (as passed to the --foo_out
// parameter); if omitted, the current directory should be used. --parameter
// gives the generator parameter, if any was provided. The PROTO_FILES list
// the .proto files which were given on the compiler command-line; these are
// the files for which the plugin is expected to generate output code.
// Finally, DESCRIPTORS is an encoded FileDescriptorSet (as defined in
// descriptor.proto). This is piped to the plugin's stdin. The set will
// include descriptors for all the files listed in PROTO_FILES as well as
// all files that they import. The plugin MUST NOT attempt to read the
// PROTO_FILES directly -- it must use the FileDescriptorSet.
//
// The plugin should generate whatever files are necessary, as code generators
// normally do. It should write the names of all files it generates to
// stdout. The names should be relative to the output directory, NOT absolute
// names or relative to the current directory. If any errors occur, error
// messages should be written to stderr. If an error is fatal, the plugin
// should exit with a non-zero exit code.

// - You want to parse .proto files at runtime. In this case, you should
// look at importer.h. Since this functionality is widely useful, it is
// included in the libprotobuf base library; you do not have to link against
// libprotoc.
// - You want to write a custom protocol compiler which generates different
// kinds of code, e.g. code in a different language which is not supported
// by the official compiler. For this purpose, command_line_interface.h
// provides you with a complete compiler front-end, so all you need to do
// is write a custom implementation of CodeGenerator and a trivial main()
// function. You can even make your compiler support the official languages
// in addition to your own. Since this functionality is only useful to those
// writing custom compilers, it is in a separate library called "libprotoc"
// which you will have to link against.

// Front-end for protoc code generator plugins written in C++.
//
// To implement a protoc plugin in C++, simply write an implementation of
// CodeGenerator, then create a main() function like:
// int main(int argc, char* argv[]) {
// MyCodeGenerator generator;
// return google::protobuf::compiler::PluginMain(argc, argv, &generator);
// }
// You must link your plugin against libprotobuf and libprotoc.
//
// To get protoc to use the plugin, do one of the following:
// * Place the plugin binary somewhere in the PATH and give it the name
// "protoc-gen-NAME" (replacing "NAME" with the name of your plugin). If you
// then invoke protoc with the parameter --NAME_out=OUT_DIR (again, replace
// "NAME" with your plugin's name), protoc will invoke your plugin to generate
// the output, which will be placed in OUT_DIR.
// * Place the plugin binary anywhere, with any name, and pass the --plugin
// parameter to protoc to direct it to your plugin like so:
// protoc --plugin=protoc-gen-NAME=path/to/mybinary --NAME_out=OUT_DIR
// On Windows, make sure to include the .exe suffix:
// protoc --plugin=protoc-gen-NAME=path/to/mybinary.exe --NAME_out=OUT_DIR

// to be defined in any other file. In particular, if a file defines a symbol
// "Foo", then searching for "Foo.[anything]" will match that file. This way,
// the database does not need to aggressively index all children of a symbol.
//
// FindFileContainingExtension() is mostly-implemented. It works if and only
// if the original FieldDescriptorProto defining the extension has a
// fully-qualified type name in its "extendee" field (i.e. starts with a '.').
// If the extendee is a relative name, SimpleDescriptorDatabase will not

// extension's containing type will never actually find that extension. Note
// that this is an unlikely problem, as all FileDescriptorProtos created by the
// protocol compiler (as well as ones created by calling

// prefixes of other symbols in the map. For example, "foo.bar" is a
// prefix of "foo.bar.baz" (but is not a prefix of "foo.barbaz").
//
// This invariant is important because it means that given a symbol name,
// we can find a key in the map which is a prefix of the symbol in O(lg n)
// time, and we know that there is at most one such key.
//
// The prefix lookup algorithm works like so:
// 1) Find the last key in the map which is less than or equal to the
// search key.
// 2) If the found key is a prefix of the search key, then return it.
// Otherwise, there is no match.
//
// I am sure this algorithm has been described elsewhere, but since I
// wasn't able to find it quickly I will instead prove that it works
// myself. The key to the algorithm is that if a match exists, step (1)
// will find it. Proof:
// 1) Define the "search key" to be the key we are looking for, the "found
// key" to be the key found in step (1), and the "match key" to be the
// key which actually matches the serach key (i.e. the key we're trying
// to find).
// 2) The found key must be less than or equal to the search key by
// definition.
// 3) The match key must also be less than or equal to the search key
// (because it is a prefix).
// 4) The match key cannot be greater than the found key, because if it
// were, then step (1) of the algorithm would have returned the match
// key instead (since it finds the *greatest* key which is less than or
// equal to the search key).
// 5) Therefore, the found key must be between the match key and the search
// key, inclusive.
// 6) Since the search key must be a sub-symbol of the match key, if it is
// not equal to the match key, then search_key[match_key.size()] must
// be '.'.
// 7) Since '.' sorts before any other character that is valid in a symbol
// name, then if the found key is not equal to the match key, then
// found_key[match_key.size()] must also be '.', because any other value
// would make it sort after the search key.
// 8) Therefore, if the found key is not equal to the match key, then the
// found key must be a sub-symbol of the match key. However, this would
// contradict our map invariant which says that no symbol in the map is
// a sub-symbol of any other.
// 9) Therefore, the found key must match the match key.
//
// The above proof assumes the match key exists. In the case that the
// match key does not exist, then step (1) will return some other symbol.
// That symbol cannot be a super-symbol of the search key since if it were,
// then it would be a match, and we're assuming the match key doesn't exist.

// DynamicMessage is implemented by constructing a data structure which
// has roughly the same memory layout as a generated message would have.
// Then, we use GeneratedMessageReflection to implement our reflection
// interface. All the other operations we need to implement (e.g.
// parsing, copying, etc.) are already implemented in terms of
// Reflection, so the rest is easy.
//
// The up side of this strategy is that it's very efficient. We don't
// need to use hash_maps or generic representations of fields. The
// down side is that this is a low-level memory management hack which
// can be tricky to get right.
//
// As mentioned in the header, we only expose a DynamicMessageFactory
// publicly, not the DynamicMessage class itself. This is because
// GenericMessageReflection wants to have a pointer to a "default"
// copy of the class, with all fields initialized to their default
// values. We only want to construct one of these per message type,
// so DynamicMessageFactory stores a cache of default messages for
// each type it sees (each unique Descriptor pointer). The code
// refers to the "default" copy of the class as the "prototype".
//
// Note on memory allocation: This module often calls "operator new()"
// to allocate untyped memory, rather than calling something like
// "new uint8[]". This is because "operator new()" means "Give me some
// space which I can use as I please." while "new uint8[]" means "Give
// me an array of 8-bit integers.". In practice, the later may return
// a pointer that is not aligned correctly for general use. I believe
// Item 8 of "More Effective C++" discusses this in more detail, though
// I don't have the book on me right now so I'm not sure.

// Glue for generated extension accessors
// -------------------------------------------------------------------
// Template magic
// First we have a set of classes representing "type traits" for different
// field types. A type traits class knows how to implement basic accessors
// for extensions of a particular type given an ExtensionSet. The signature
// for a type traits class looks like this:
//
// class TypeTraits {
// public:
// typedef ? ConstType;
// typedef ? MutableType;
//
// static inline ConstType Get(int number, const ExtensionSet& set);
// static inline void Set(int number, ConstType value, ExtensionSet* set);
// static inline MutableType Mutable(int number, ExtensionSet* set);
//
// // Variants for repeated fields.
// static inline ConstType Get(int number, const ExtensionSet& set,
// int index);
// static inline void Set(int number, int index,
// ConstType value, ExtensionSet* set);
// static inline MutableType Mutable(int number, int index,
// ExtensionSet* set);
// static inline void Add(int number, ConstType value, ExtensionSet* set);
// static inline MutableType Add(int number, ExtensionSet* set);
// };
//
// Not all of these methods make sense for all field types. For example, the
// "Mutable" methods only make sense for strings and messages, and the
// repeated methods only make sense for repeated types. So, each type
// traits class implements only the set of methods from this signature that it
// actually supports. This will cause a compiler error if the user tries to
// access an extension using a method that doesn't make sense for its type.
// For example, if "foo" is an extension of type "optional int32", then if you
// try to write code like:
// my_message.MutableExtension(foo)
// you will get a compile error because PrimitiveTypeTraits<int32> does not
// have a "Mutable()" method.

// we must explicitly define the methods of the type traits class for each
// known type.

// A GeneratedMessageReflection is an implementation of Reflection

// memory. The locations are given using a base pointer and a set of
// offsets.
//
// It is required that the user represents fields of each type in a standard
// way, so that GeneratedMessageReflection can cast the void* pointer to
// the appropriate type. For primitive fields and string fields, each field
// should be represented using the obvious C++ primitive type. Enums and
// Messages are different:
// - Singular Message fields are stored as a pointer to a Message. These
// should start out NULL, except for in the default instance where they
// should start out pointing to other default instances.
// - Enum fields are stored as an int. This int must always contain
// a valid value, such that EnumDescriptor::FindValueByNumber() would
// not return NULL.
// - Repeated fields are stored as RepeatedFields or RepeatedPtrFields
// of whatever type the individual field would be. Strings and
// Messages use RepeatedPtrFields while everything else uses
// RepeatedFields.

// embedded message fields *must* have non-NULL pointers
// in the default instance.)
// offsets: An array of ints giving the byte offsets, relative to
// the start of the message object, of each field. These can
// be computed at compile time using the
// GOOGLE_PROTOBUF_GENERATED_MESSAGE_FIELD_OFFSET() macro, defined
// below.
// has_bits_offset: Offset in the message of an array of uint32s of size
// descriptor->field_count()/32, rounded up. This is a
// bitfield where each bit indicates whether or not the
// corresponding field of the message has been initialized.
// The bit for field index i is obtained by the expression:

// unknown_fields_offset: Offset in the message of the UnknownFieldSet for

// extensions_offset: Offset in the message of the ExtensionSet for the

// ranges.
// pool: DescriptorPool to search for extension definitions. Only

// There are some places in proto2 where dynamic_cast would be useful as an

// For a given generated message FooMessage, we generate these two methods:
// void MergeFrom(const FooMessage& other);
// void MergeFrom(const Message& other);
// The former method can be implemented directly in terms of FooMessage's

// That said, dynamic_cast requires RTTI, which many people like to disable

// Here we have a hand-written lexer. At first you might ask yourself,
// "Hand-written text processing? Is Kenton crazy?!" Well, first of all,
// yes I am crazy, but that's beside the point. There are actually reasons
// why I ended up writing this this way.
//
// The traditional approach to lexing is to use lex to generate a lexer for
// you. Unfortunately, lex's output is ridiculously ugly and difficult to
// integrate cleanly with C++ code, especially abstract code or code meant
// as a library. Better parser-generators exist but would add dependencies
// which most users won't already have, which we'd like to avoid. (GNU flex
// has a C++ output option, but it's still ridiculously ugly, non-abstract,
// and not library-friendly.)
//
// The next approach that any good software engineer should look at is to
// use regular expressions. And, indeed, I did. I have code which
// implements this same class using regular expressions. It's about 200
// lines shorter. However:
// - Rather than error messages telling you "This string has an invalid
// escape sequence at line 5, column 45", you get error messages like
// "Parse error on line 5". Giving more precise errors requires adding
// a lot of code that ends up basically as complex as the hand-coded
// version anyway.
// - The regular expression to match a string literal looks like this:
// kString = new RE("(\"([^\"\\\\]|" // non-escaped
// "\\\\[abfnrtv?\"'\\\\0-7]|" // normal escape
// "\\\\x[0-9a-fA-F])*\"|" // hex escape
// "\'([^\'\\\\]|" // Also support single-quotes.
// "\\\\[abfnrtv?\"'\\\\0-7]|"
// "\\\\x[0-9a-fA-F])*\')");
// Verifying the correctness of this line noise is actually harder than
// verifying the correctness of ConsumeString(), defined below. I'm not
// even confident that the above is correct, after staring at it for some
// time.
// - PCRE is fast, but there's still more overhead involved than the code
// below.
// - Sadly, regular expressions are not part of the C standard library, so
// using them would require depending on some other library. For the
// open source release, this could be really annoying. Nobody likes
// downloading one piece of software just to find that they need to
// download something else to make it work, and in all likelihood
// people downloading Protocol Buffers will already be doing so just
// to make something else work. We could include a copy of PCRE with
// our code, but that obligates us to keep it up-to-date and just seems
// like a big waste just to save 200 lines of code.
//
// On a similar but unrelated note, I'm even scared to use ctype.h.
// Apparently functions like isalpha() are locale-dependent. So, if we used
// that, then if this code is being called from some program that doesn't
// have its locale set to "C", it would behave strangely. We can't just set
// the locale to "C" ourselves since we might break the calling program that
// way, particularly if it is multi-threaded. WTF? Someone please let me
// (Kenton) know if I'm missing something here...
//
// I'd love to hear about other alternatives, though, as this code isn't
// exactly pretty.

//
// This file contains the ZeroCopyInputStream and ZeroCopyOutputStream
// interfaces, which represent abstract I/O streams to and from which
// protocol buffers can be read and written. For a few simple
// implementations of these interfaces, see zero_copy_stream_impl.h.
//
// These interfaces are different from classic I/O streams in that they
// try to minimize the amount of data copying that needs to be done.
// To accomplish this, responsibility for allocating buffers is moved to
// the stream object, rather than being the responsibility of the caller.
// So, the stream can return a buffer which actually points directly into
// the final data structure where the bytes are to be stored, and the caller
// can interact directly with that buffer, eliminating an intermediate copy
// operation.
//
// As an example, consider the common case in which you are reading bytes
// from an array that is already in memory (or perhaps an mmap()ed file).
// With classic I/O streams, you would do something like:
// char buffer[BUFFER_SIZE];
// input->Read(buffer, BUFFER_SIZE);
// DoSomething(buffer, BUFFER_SIZE);
// Then, the stream basically just calls memcpy() to copy the data from
// the array into your buffer. With a ZeroCopyInputStream, you would do
// this instead:
// const void* buffer;
// int size;
// input->Next(&buffer, &size);
// DoSomething(buffer, size);
// Here, no copy is performed. The input stream returns a pointer directly
// into the backing array, and the caller ends up reading directly from it.
//
// If you want to be able to read the old-fashion way, you can create
// a CodedInputStream or CodedOutputStream wrapping these objects and use
// their ReadRaw()/WriteRaw() methods. These will, of course, add a copy
// step, but Coded*Stream will handle buffering so at least it will be
// reasonably efficient.
//
// ZeroCopyInputStream example:
// // Read in a file and print its contents to stdout.
// int fd = open("myfile", O_RDONLY);
// ZeroCopyInputStream* input = new FileInputStream(fd);
//
// const void* buffer;
// int size;
// while (input->Next(&buffer, &size)) {
// cout.write(buffer, size);
// }
//
// delete input;
// close(fd);
//
// ZeroCopyOutputStream example:
// // Copy the contents of "infile" to "outfile", using plain read() for
// // "infile" but a ZeroCopyOutputStream for "outfile".
// int infd = open("infile", O_RDONLY);
// int outfd = open("outfile", O_WRONLY);
// ZeroCopyOutputStream* output = new FileOutputStream(outfd);
//
// void* buffer;
// int size;
// while (output->Next(&buffer, &size)) {
// int bytes = read(infd, buffer, size);
// if (bytes < size) {
// // Reached EOF.
// output->BackUp(size - bytes);
// break;
// }
// }
//
// delete output;
// close(infd);
// close(outfd);

// Defines Message, the abstract interface implemented by non-lite
// protocol message objects. Although it's possible to implement this
// interface manually, most users will use the protocol compiler to
// generate implementations.
//
// Example usage:
//
// Say you have a message defined as:
//
// message Foo {
// optional string text = 1;
// repeated int32 numbers = 2;
// }
//
// Then, if you used the protocol compiler to generate a class from the above
// definition, you could use it like so:
//
// string data; // Will store a serialized version of the message.
//
// {
// // Create a message and serialize it.
// Foo foo;
// foo.set_text("Hello World!");
// foo.add_numbers(1);
// foo.add_numbers(5);
// foo.add_numbers(42);
//
// foo.SerializeToString(&data);
// }
//
// {
// // Parse the serialized message and check that it contains the
// // correct data.
// Foo foo;
// foo.ParseFromString(data);
//
// assert(foo.text() == "Hello World!");
// assert(foo.numbers_size() == 3);
// assert(foo.numbers(0) == 1);
// assert(foo.numbers(1) == 5);
// assert(foo.numbers(2) == 42);
// }
//
// {
// // Same as the last block, but do it dynamically via the Message
// // reflection interface.
// Message* foo = new Foo;
// Descriptor* descriptor = foo->GetDescriptor();
//
// // Get the descriptors for the fields we're interested in and verify
// // their types.
// FieldDescriptor* text_field = descriptor->FindFieldByName("text");
// assert(text_field != NULL);
// assert(text_field->type() == FieldDescriptor::TYPE_STRING);
// assert(text_field->label() == FieldDescriptor::TYPE_OPTIONAL);
// FieldDescriptor* numbers_field = descriptor->FindFieldByName("numbers");
// assert(numbers_field != NULL);
// assert(numbers_field->type() == FieldDescriptor::TYPE_INT32);
// assert(numbers_field->label() == FieldDescriptor::TYPE_REPEATED);
//
// // Parse the message.
// foo->ParseFromString(data);
//
// // Use the reflection interface to examine the contents.
// const Reflection* reflection = foo->GetReflection();
// assert(reflection->GetString(foo, text_field) == "Hello World!");
// assert(reflection->FieldSize(foo, numbers_field) == 3);
// assert(reflection->GetRepeatedInt32(foo, numbers_field, 0) == 1);

// To get the Reflection for a given Message, call Message::GetReflection().
//
// This interface is separate from Message only for efficiency reasons;
// the vast majority of implementations of Message will share the same
// implementation of Reflection (GeneratedMessageReflection,
// defined in generated_message.h), and all Messages of a particular class
// should share the same Reflection object (though you should not rely on
// the latter fact).
//
// There are several ways that these methods can be used incorrectly. For
// example, any of the following conditions will lead to undefined
// results (probably assertion failures):
// - The FieldDescriptor is not a field of this message type.
// - The method called is not appropriate for the field's type. For
// each field type in FieldDescriptor::TYPE_*, there is only one
// Get*() method, one Set*() method, and one Add*() method that is
// valid for that type. It should be obvious which (except maybe
// for TYPE_BYTES, which are represented using strings in C++).
// - A Get*() or Set*() method for singular fields is called on a repeated
// field.
// - GetRepeated*(), SetRepeated*(), or Add*() is called on a non-repeated
// field.
// - The Message object passed to any method is not of the right type for
// this Reflection object (i.e. message.GetReflection() != reflection).
//
// You might wonder why there is not any abstract representation for a field
// of arbitrary type. E.g., why isn't there just a "GetField()" method that
// returns "const Field&", where "Field" is some class with accessors like
// "GetInt32Value()". The problem is that someone would have to deal with
// allocating these Field objects. For generated message classes, having to
// allocate space for an additional object to wrap every field would at least
// double the message's memory footprint, probably worse. Allocating the
// objects on-demand, on the other hand, would be expensive and prone to
// memory leaks. So, instead we ended up with this flat interface.

// Message interface, by adding the following line to the .proto file:
//
// option optimize_for = LITE_RUNTIME;

// This is particularly useful on resource-constrained systems where
// the full protocol buffers runtime library is too big.
//
// Note that on non-constrained systems (e.g. servers) when you need
// to link in lots of protocol definitions, a better way to reduce
// total code footprint is to use optimize_for = CODE_SIZE. This
// will make the generated code smaller while still supporting all the
// same features (at the expense of speed). optimize_for = LITE_RUNTIME
// is best when you only have a small number of message types linked
// into your binary, in which case the size of the protocol buffers
// runtime itself is the biggest problem.

// not safe to access that object in any other thread simultaneously.
//
// Put simply, read-only access to an object can happen in multiple threads
// simultaneously, but write access can only happen in a single thread at
// a time.
//
// The implementation does contain some "const" methods which actually modify
// the object behind the scenes -- e.g., to cache results -- but in these cases
// mutex locking is used to make the access thread-safe.

// DEPRECATED: This module declares the abstract interfaces underlying proto2
// RPC services. These are intented to be independent of any particular RPC
// implementation, so that proto2 services can be used on top of a variety
// of implementations. Starting with version 2.3.0, RPC implementations should
// not try to build on these, but should instead provide code generator plugins
// which generate code specific to the particular RPC implementation. This way
// the generated code can be more appropriate for the implementation in use
// and can avoid unnecessary layers of indirection.
//
//
// When you use the protocol compiler to compile a service definition, it
// generates two classes: An abstract interface for the service (with
// methods matching the service definition) and a "stub" implementation.
// A stub is just a type-safe wrapper around an RpcChannel which emulates a
// local implementation of the service.
//
// For example, the service definition:
// service MyService {
// rpc Foo(MyRequest) returns(MyResponse);
// }
// will generate abstract interface "MyService" and class "MyService::Stub".
// You could implement a MyService as follows:
// class MyServiceImpl : public MyService {
// public:
// MyServiceImpl() {}
// ~MyServiceImpl() {}
//
// // implements MyService ---------------------------------------
//
// void Foo(google::protobuf::RpcController* controller,
// const MyRequest* request,
// MyResponse* response,
// Closure* done) {
// // ... read request and fill in response ...
// done->Run();
// }
// };
// You would then register an instance of MyServiceImpl with your RPC server
// implementation. (How to do that depends on the implementation.)
//
// To call a remote MyServiceImpl, first you need an RpcChannel connected to it.
// How to construct a channel depends, again, on your RPC implementation.
// Here we use a hypothentical "MyRpcChannel" as an example:
// MyRpcChannel channel("rpc:hostname:1234/myservice");
// MyRpcController controller;
// MyServiceImpl::Stub stub(&channel);
// FooRequest request;
// FooRespnose response;
//
// // ... fill in request ...
//
// stub.Foo(&controller, request, &response, NewCallback(HandleResponse));
//
// On Thread-Safety:
//
// Different RPC implementations may make different guarantees about what
// threads they may run callbacks on, and what threads the application is
// allowed to use to call the RPC system. Portable software should be ready
// for callbacks to be called on any thread, but should not try to call the
// RPC system from any thread except for the ones on which it received the
// callbacks. Realistically, though, simple software will probably want to
// use a single-threaded RPC system while high-end software will want to
// use multiple threads. RPC implementations should provide multiple
// choices.
