upb.git - a small protobuf implementation in C

2011-05-20	Add startseq/endseq handlers.	Joshua Haberman
	Startseq/endseq handlers are called at the beginning and end of a sequence of repeated values. Protobuf does not really have direct support for this (repeated primitive fields do not delimit "begin" and "end" of the sequence) but we can infer them from the bytestream. The benefit of supporting them explicitly is that they get their own stack frame and closure, so we can avoid having to find the array's address over and over and deciding if we need to initialize it. This will also pave the way for better support of JSON, which does have explicit "startseq/endseq" markers: [].
2011-05-10	Vastly improved/simplified the upb_handlers API.	Joshua Haberman

2011-05-08	Documentation, some type renaming, nix unknown handler for now.	Joshua Haberman

2011-05-08	Split upb_stream -> upb_bytestream/upb_handlers.	Joshua Haberman

2011-04-01	First rough version of the JIT.	Joshua Haberman
	It can successfully parse SpeedMessage1. Preliminary results: 750MB/s on Core2 2.4GHz. This number is 2.5x proto2. This isn't apples-to-apples, because proto2 is parsing to a struct and we are just doing stream parsing, but for apps that are currently using proto2, this is the improvement they would see if they could move to stream-based processing. Unfortunately perf-regression-test.py is broken, and I'm not 100% sure why. It would be nice to fix it first (to ensure that there are no performance regressions for the table-based decoder) but I'm really impatient to get the JIT checked in.
2011-02-22	Major work on Lua extension and default values.	Joshua Haberman
	Default values are now supported, and the Lua extension can now create and modify individual protobuf objects.
2011-02-10	Add (but do not activate) an SSE varint decoder.	Joshua Haberman

2011-02-06	All tests pass again, valgrind-clean! Next up: benchmarks.	Joshua Haberman

2010-01-15	Remove struct keyword from all types, use typedef instead.	Joshua Haberman

2010-01-15	upb_parser -> upb_decoder	Joshua Haberman

2010-01-05	Ported/fixed tests to new data types.	Joshua Haberman

2010-01-01	Bugfixes: descriptorgen works without leaks!	Joshua Haberman

2009-12-06	Truly fixed type cyclic refcounting.	Joshua Haberman

2009-12-05	Add a test for circularly-linked descriptors.	Joshua Haberman
	The test currently triggers valgrind-detected memory errors.
2009-12-05	Make defs refcounted, rename upb_context->upbsymtab.	Joshua Haberman
	There is currently a memory leak when type definitions form cycles. This will need to be dealt with.
2009-11-14	Changed parse API to know about msgdefs.	Joshua Haberman
	This should make it both easier to use and easier to optimize, in exchange for a small amount of generality. In practice, any remotely normal case is still very natural.
2009-11-14	Refactoring: split defs into their own file, move private parsing funcs out ↵	Joshua Haberman
	of .h file.
2009-09-26	Use a status object for errors so a message can be returned.	Joshua Haberman
	Also delay deletion of subfields until the entire message is deleted.
2009-08-28	Incremental improvements to cbparser, and a test.	Joshua Haberman

2009-08-15	Finish upb_context thread-safety.	Joshua Haberman

2009-08-15	Add refcounting and thread-safety to message definitions.	Joshua Haberman

2009-08-03	Fix tests (and src) such that all tests pass again.	Joshua Haberman

2009-08-01	Added a proper prototype for upb_serialize.	Joshua Haberman

2009-07-25	Move parsing functions to header file in anticipation of code generation ↵	Joshua Haberman
	(want them inlined).
2009-07-23	upb is fully self-hosting (except for text->descriptor)!	Joshua Haberman

2009-07-21	Fix tests and the build (though a few tests are failing).	Joshua Haberman

2009-07-17	Enhanced testing.	Joshua Haberman

2009-07-08	Directory restructuring.	Joshua Haberman
