2011-08-08	Begin port of Python extension to new APIs.	Joshua Haberman

2011-08-04	More work on Lua extension, and consequent core refactoring.	Joshua Haberman

2011-07-31	More work on Lua extension.	Joshua Haberman

2011-07-31	Fixed "make descriptorgen".	Joshua Haberman

2011-07-29	Significant work on Lua extension.	Joshua Haberman
	Also changes in core library to accommodate.
2011-07-19	Added comment about how to disassemble JIT output.	Joshua Haberman

2011-07-16	Get rid of upb_symtabtxn.	Joshua Haberman
	This type was nothing but a map of defs. We can as easily just pass an array of defs into upb_symtab_add().
2011-07-15	Make Lua extension build again.	Joshua Haberman

2011-07-15	Directory restructure.	Joshua Haberman
	Includes are now via upb/foo.h. Files specific to the protobuf format are now in upb/pb (the core library is concerned with message definitions, handlers, and byte streams, but knows nothing about any particular serializationf format).
2011-07-14	Major refactoring: upb_string is gone in favor of upb_strref.	Joshua Haberman

2011-06-17	Major refactoring: abandon upb_msg, add upb_accessors.	Joshua Haberman
	Next on the chopping block is upb_string.
2011-05-21	Make all handlers objects refcounted.	Joshua Haberman
	I'm realizing that basically all upb objects will need to be refcounted to be sharable across languages, but not messages which are on their way out so we can get out of the business of data representations. Things which must be refcounted: - encoders, decoders - handlers objects - defs
2011-05-21	Add proof-of-concept C++ wrapper header.	Joshua Haberman

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: [].
2011-05-20	JIT: factor out push/pop frame into macros.	Josh Haberman

2011-05-19	Change dispatcher error handling model.	Joshua Haberman
	Now the dispatcher will call error handlers instaed of returning statuses that the caller has to constantly check.
2011-05-10	Fix JIT for new interface.	Joshua Haberman

2011-05-10	Fix aliasing violation.	Joshua Haberman

2011-05-10	Vastly improved/simplified the upb_handlers API.	Joshua Haberman

2011-05-08	More renaming.	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

2011-05-08	Decoder redesign in preparation for packed fields and start/endseq.	Joshua Haberman

2011-05-06	Refactor varint encoding/decoding.	Joshua Haberman

2011-04-25	Revise/clarify comment about clear() implementation.	Joshua Haberman

2011-04-15	Calculate and print string sizes in test messages.	Joshua Haberman

2011-04-15	Merge branch 'master' of git@github.com:haberman/upb	Joshua Haberman

2011-04-14	Fix GDB JIT registration on Linux.	Joshua Haberman

2011-04-08	Small change to make Lua extension compile again.	Joshua Haberman

2011-04-06	JIT now works on OS X!	Joshua Haberman
	Had to fix the case where the jump table was allocated in a >4GB address.
2011-04-06	Disable GDB JIT interface on OS X.	Josh Haberman
	OS X doesn't use ELF, so our little trick doesn't work there.
2011-04-05	Update README and fix small decoder issue.	Joshua Haberman

2011-04-04	Speed up parsetostruct by using type-specialized callbacks.	Joshua Haberman

2011-04-02	JIT passes all tests!	Joshua Haberman

2011-04-01	Whoops, add src/jit_debug_elf_file.s	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.
2011-03-28	Switch to non-branching varint decoder.	Joshua Haberman

2011-03-26	Small semantics changes in the decoder.	Josh Haberman
	Simplified some of the semantics around the decoder's data structures, in anticipation of sharing them between the regular C decoder and a JIT-ted decoder.
