Joshua Haberman	9cb10577fc	First version of a real C codegen for upb. Also includes an implementation of the conformance tests to display what the API usage will be like. There is still a lot to do, and things that are broken (oneofs, repeated fields, etc), but it's a good start.	8 years ago
Josh Haberman	e9d79d2441	Added upb::FileDef, which represents the file defs are declared in. It is entirely optional: MessageDef/EnumDef can still exist on their own. But this can represent a def's file when it is desirable to do so (eg. for code generators). This approach will require that we change the way we handle extensions. But I think it will be a good change overall. Specifically, we previously handled extensions by duplicating the extended message and then adding the extension as a regular field to the duplicated message. This required also duplicating any messages that could reach the extended message. In the new world we will need a way of declaring and looking up extensions separately from the message being extended. This change also involves some notable changes to the generated code: - files are now called foo.upbdefs.h instead of foo.upb.h. This reflects the fact that we might possibly generate several different output files for a .proto file, and this one is just for defs. - we no longer generate selectors in the .h file. - the upbdefs.c no longer vends a SymbolTable. Now it vends the individual messages (and possibly a FileDef later). I think this will compose better once we can generate files where one generated files imports another. We also make the descriptor reader vend a list of FileDefs now. This is the best conceptual match for parsing a FileDescriptorSet.	9 years ago

Josh Haberman	919fea438a	Ported upb to C89, for greater portability. A large part of this change contains surface-level porting, like moving variable declarations to the top of the block. However there are a few more substantial things too: - moved internal-only struct definitions to a separate file (structdefs.int.h), for greater encapsulation and ABI compatibility. - removed the UPB_UPCAST macro, since it requires access to the internal-only struct definitions. Replaced uses with calls to inline, type-safe casting functions. - removed the UPB_DEFINE_CLASS/UPB_DEFINE_STRUCT macros. Class and struct definitions are now more explicit -- you get to see the actual class/struct keywords in the source. The casting convenience functions have been moved into UPB_DECLARE_DERIVED_TYPE() and UPB_DECLARE_DERIVED_TYPE2(). - the new way that we duplicate base methods in derived types is also more convenient and requires less duplication. It is also less greppable, but hopefully that is not too big a problem. Compiler flags (-std=c89 -pedantic) should help to rigorously enforce that the code is free of C99-isms. A few functions are not available in C89 (strtoll). There are temporary, hacky solutions in place.	10 years ago

Josh Haberman	26d98ca94f	Merge from Google-internal development: - rewritten decoder; interpreted decoder is bytecode-based, JIT decoder no longer falls back to the interpreter. - C++ improvements: C++11-compatible iterators, upb::reffed_ptr for RAII refcounting, better upcast/downcast support. - removed the gross upb_value abstraction from public upb.h.	11 years ago
Josh Haberman	bada1e94f4	Merge from Google-internal development. - Better error reporting for upb::Def setters. - error reporting for upb::Handlers setters. - made the start/endmsg handlers a little less special-cased.	12 years ago
Josh Haberman	90bb4246c3	Synced with Google-internal development. C++ handlers are now type-safe; SinkFrame is gone. Various other changes.	12 years ago
Josh Haberman	cfdb9907cb	Synced with 3 months of Google-internal development. Major changes: - Got rid of all bytestream interfaces in favor of using regular handlers. - new Pipeline object represents a upb pipeline, does bump allocation internally to manage memory. - proto2 support now can handle extensions.	12 years ago
Josh Haberman	7d3e2bd2c4	Sync with 8 months of Google-internal development. Many things have changed and been simplified. The memory-management story for upb_def and upb_handlers is much more robust; upb_def and upb_handlers should be fairly stable interfaces now. There is still much work to do for the runtime component (upb_sink).	12 years ago
