upb.git - a small protobuf implementation in C

Age	Commit message (Collapse)	Author
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

2011-05-21	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
2011-05-20	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: [].

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

2011-04-14	Fix GDB JIT registration on Linux.	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.
2011-04-04	Speed up parsetostruct by using type-specialized callbacks.	Joshua Haberman

2011-04-02	JIT passes all tests!	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.
