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

Martin Maly	508c39ee13	Resolve compilation errors if compiled with more stringent semantic checks. Adding Travis test to build with strict warnings. Fixing a warning in a test which used signed/unsigned integer comparison.	10 years ago
Chris Fallin	099d57346a	Fixed JSON parser issue: missing NUL byte in parse_number() in some code paths. Also, fix unused-function warnings.	10 years ago
Chris Fallin	fb58504569	Support maps in JSON parsing and serialization. This is a sync of our internal developing of JSON parsing and serialization. It implements native understanding of MapEntry submessages, so that map fields with (key, value) pairs are serialized as JSON maps (objects) natively rather than as arrays of objects with 'key' and 'value' fields. The parser also now understands how to emit handler calls corresponding to MapEntry objects when processing a map field. This sync also picks up a bugfix in `table.c` to handle an alloc-failed case.	10 years ago
Chris Fallin	87a18f3774	Support oneof defs in upb. This change adds support for a OneofDef (upb_oneofdef), which represents a 'oneof' as introduced by Protocol Buffers. This is semantically a union type that contains fields and in turn may be added to a MessageDef. This change does not alter parsing or the handler abstraction in any way, because a oneof has impact only at a higher semantic level (i.e., any sort of storage of the fields in a message object), which is user-specific with respect to upb.	10 years ago
Chris Fallin	b3f6daf83d	Amalgamated distribution (upb.c/upb.h) tool. There are a number of tweaks to get this to work: - The #include dependence graph wasn't quite complete, and I had to add a few #includes to get the tool to work. - I had to change a number of symbol names to avoid conflicts between 'static' definitions in different .c files. This could be avoided if the tool were smart enough to rename static symbols to have unique prefixes instead, but (i) this requires semantic understanding of C, and (ii) the macro-defined static functions (e.g., handlers for primitive types in several places) would probably trip this up. Verified that the resulting upb.h/upb.c compiles and doesn't have any unresolved references.	10 years ago
Chris Fallin	8f8113b4ff	JSON test, symbolic enum names in JSON, and a few improvements. - Added a JSON test that round-trips (parses then re-serializes) several test messages, ensuring that the re-serialized form matches the original exactly. - Added support for printing and parsing symbolic enum names (rather than integer values) in JSON. - Updated JSON printer to properly handle string fields that come in multiple pieces. ('bytes' fields still do not support this, and this work is more challenging because it requires making the base64 encoder resumable. Base64 encoding is not separable at an input-byte granularity, unlike string escaping.) - Fixed a < vs. <= bug in UTF-8 encoding generation (oops).	10 years ago
