It is not + // sufficient for it to simply contain a descriptor that has the same name + // and content -- it must be the *exact object*. In other words: + // assert(pool->FindMessageTypeByName(m->GetDescriptor()->full_name()) == + // m->GetDescriptor()); + // There are two ways to satisfy this requirement: + // 1) Use m->GetDescriptor()->pool() as the pool. This is generally useless + // because this is the pool that would be used anyway if you didn't call + // SetExtensionRegistry() at all. + // 2) Use a DescriptorPool which has m->GetDescriptor()->pool() as an + // "underlay". Read the documentation for DescriptorPool for more + // information about underlays. + // + // You must also provide a MessageFactory. This factory will be used to + // construct Message objects representing extensions. The factory's + // GetPrototype() MUST return non-NULL for any Descriptor which can be found + // through the provided pool. + // + // If the provided factory might return instances of protocol-compiler- + // generated (i.e. compiled-in) types, or if the outer message object m is + // a generated type, then the given factory MUST have this property: If + // GetPrototype() is given a Descriptor which resides in + // DescriptorPool::generated_pool(), the factory MUST return the same + // prototype which MessageFactory::generated_factory() would return.

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?

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.

See the Service interface +// in service.h. +// +// To automatically construct a Closure which calls a particular function or +// method with a particular set of parameters, use the NewCallback() function. +// Example: +// void FooDone(const FooResponse* response) { +// ... +// } +// +// void CallFoo() { +// ... +// // When done, call FooDone() and pass it a pointer to the response. +// Closure* callback = NewCallback(&FooDone, response); +// // Make the call. +// service->Foo(controller, request, response, callback); +// } +// +// Example that calls a method: +// class Handler { +// public: +// ... +// +// void FooDone(const FooResponse* response) { +// ... +// } +// +// void CallFoo() { +// ... +// // When done, call FooDone() and pass it a pointer to the response. +// Closure* callback = NewCallback(this, &Handler::FooDone, response); +// // Make the call. +// service->Foo(controller, request, response, callback); +// } +// }; +// +// Currently NewCallback() supports binding zero, one, or two arguments. +// +// Callbacks created with NewCallback() automatically delete themselves when +// executed. They should be used when a callback is to be called exactly +// once (usually the case with RPC callbacks). If a callback may be called +// a different number of times (including zero), create it with +// NewPermanentCallback() instead. You are then responsible for deleting the +// callback (using the "delete" keyword as normal). +// +// Note that NewCallback() is a bit touchy regarding argument types. Generally, +// the values you provide for the parameter bindings must exactly match the +// types accepted by the callback function. For example: +// void Foo(string s); +// NewCallback(&Foo, "foo"); // WON'T WORK: const char* != string +// NewCallback(&Foo, string("foo")); // WORKS +// Also note that the arguments cannot be references: +// void Foo(const string& s); +// string my_str; +// NewCallback(&Foo, my_str); // WON'T WORK: Can't use referecnes. +// However, correctly-typed pointers will work just fine. +class LIBPROTOBUF_EXPORT Closure { + public: + Closure() {} + virtual ~Closure();

This assures that enough bytes are output + in order for the decompressor to finish the block before the empty fixed code + block. + + If flush is set to Z_BLOCK, a deflate block is completed and emitted, as + for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to + seven bits of the current block are held to be written as the next byte after + the next deflate block is completed. In this case, the decompressor may not + be provided enough bits at this point in order to complete decompression of + the data provided so far to the compressor. It may need to wait for the next + block to be emitted. This is for advanced applications that need to control + the emission of deflate blocks. + + If flush is set to Z_FULL_FLUSH, all output is flushed as with + Z_SYNC_FLUSH, and the compression state is reset so that decompression can + restart from this point if previous compressed data has been damaged or if + random access is desired.

When decoding + the zlib or gzip format, this will cause inflate() to return immediately + after the header and before the first block. When doing a raw inflate, + inflate() will go ahead and process the first block, and will return when it + gets to the end of that block, or when it runs out of data. + + The Z_BLOCK option assists in appending to or combining deflate streams. + Also to assist in this, on return inflate() will set strm->data_type to the + number of unused bits in the last byte taken from strm->next_in, plus 64 if + inflate() is currently decoding the last block in the deflate stream, plus + 128 if inflate() returned immediately after decoding an end-of-block code or + decoding the complete header up to just before the first byte of the deflate + stream. The end-of-block will not be indicated until all of the uncompressed + data from that block has been written to strm->next_out. The number of + unused bits may in general be greater than seven, except when bit 7 of + data_type is set, in which case the number of unused bits will be less than + eight. data_type is set as noted here every time inflate() returns for all + flush options, and so can be used to determine the amount of currently + consumed input in bits. + + The Z_TREES option behaves as Z_BLOCK does, but it also returns when the + end of each deflate block header is reached, before any actual data in that + block is decoded. This allows the caller to determine the length of the + deflate block header for later use in random access within a deflate block. + 256 is added to the value of strm->data_type when inflate() returns + immediately after reaching the end of the deflate block header. + + inflate() should normally be called until it returns Z_STREAM_END or an + error. However if all decompression is to be performed in a single step (a + single call of inflate), the parameter flush should be set to Z_FINISH. In + this case all pending input is processed and all pending output is flushed; + avail_out must be large enough to hold all the uncompressed data.

So the only effect of the flush parameter in this implementation + is on the return value of inflate(), as noted below, or when it returns early + because Z_BLOCK or Z_TREES is used. + + If a preset dictionary is needed after this call (see inflateSetDictionary + below), inflate sets strm->adler to the adler32 checksum of the dictionary + chosen by the compressor and returns Z_NEED_DICT; otherwise it sets + strm->adler to the adler32 checksum of all output produced so far (that is, + total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described + below. At the end of the stream, inflate() checks that its computed adler32 + checksum is equal to that saved by the compressor and returns Z_STREAM_END + only if the checksum is correct. + + inflate() can decompress and check either zlib-wrapped or gzip-wrapped + deflate data.
