upb.git - a small protobuf implementation in C

Age	Commit message (Collapse)	Author
2012-03-24	Sync from internal Google development.	Joshua Haberman
	Many improvements, too many to mention. One significant perf regression warrants investigation: omitfp.parsetoproto2_googlemessage1.upb_jit: 343 -> 252 (-26.53) plain.parsetoproto2_googlemessage1.upb_jit: 334 -> 251 (-24.85) 25% regression for this benchmark is bad, but since I don't think there's any fundamental design issue that caused it I'm going to go ahead with the commit anyway. Can investigate and fix later. Other benchmarks were neutral or showed slight improvement.
2011-09-04	Const invasion: large parts of upb made const-correct.	Joshua Haberman

2011-08-31	Header cleanup, clarify/correct comments for interfaces.	Joshua Haberman

2011-07-31	Fixed "make descriptorgen".	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).
2011-02-13	Moved upbc -> src/	Joshua Haberman

2011-02-13	Fix upbc and descriptorgen, and update descriptor.	Joshua Haberman

2010-06-26	Added constants for field names and numbers.	Joshua Haberman
	Not used in this branch, but it is used in the src-refactoring branch.
2010-01-16	Removed union tag from types.	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

2010-01-04	upb_array -> upb_arrayptr.	Joshua Haberman

2010-01-02	Move string representations back upb.h -> upb_data.h.	Joshua Haberman

2010-01-02	upb_string* -> upb_strptr, to follow aliasing rules.	Joshua Haberman

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

2009-12-31	Other than a couple memory leaks, "make descriptorgen" works again!	Joshua Haberman

2009-12-28	upbc compiles, but doesn't link due to unimplemented stuff in upb_data.	Joshua Haberman

2009-12-28	More incremental work; ported some of upbc.	Joshua Haberman

2009-12-06	Updated upbc to new dyncasts.	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	Scheme for collecting circular refs.	Joshua Haberman
	"make descriptorgen" is now valgrind-clean again.
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.
2009-11-28	Overhaul defs to derive from a common base.	Joshua Haberman

2009-11-27	Update upbc to use self-describing upb_msg instead of void*.	Joshua Haberman

2009-11-26	Make upb_msgdef own all its data.	Joshua Haberman
	This is in anticipation of making upb_msgdef's easy to dup. This involved removing all traces of any descriptors from the defs.
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	Renamed upb_msg_fielddef -> upb_fielddef, upb_enum -> upb_enumdef.	Joshua Haberman

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.
2009-08-30	Small bugfix: enums are int32, not uint32.	Joshua Haberman

2009-08-27	Fix upbc for upb_array API change.	Joshua Haberman

2009-08-24	Significant memory-management refactoring any Python extension.	Joshua Haberman

2009-08-16	Various fixes.	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

2009-08-12	Refactoring: unify upb_msg.	Joshua Haberman
	The cost is that a upb_msg will now always have an overhead of 2sizeof(void). This is comparable to proto2 overhead. The benefit is that upb_msg is now self-describing, and read-only algorithms can now operate on a upb_msg regardless of the memory-management scheme. Also, upb_array and upb_string now know inherently if they own their associated memory, and upb_array has a generic pointer for memory management purposes like upb_msg does.
2009-08-07	Fixed memory leaks in upbc.	Joshua Haberman

2009-08-07	Major refactoring of upb_msg. Temporary functionality regression.	Joshua Haberman
	There is significant refactoring here, as well as some more trivial name changes. upb_msg has become upb_msgdef, to reflect the fact that a upb_msg is not itself a message, it describes a message. There are other renamings, such as upb_parse_state -> upb_stream_parser. More significantly, the upb_msg class and parser have been refactored to reflect my recent realization about how memory management should work. upb_msg now has no memory management, and a memory mangement scheme (that works beautifully with multiple language runtimes) will be layered on top of it. This iteration has the new, read-only upb_msg. upb_mm_msg (a memory-managed message class) will come in the next change.
2009-08-02	Add a friendly comment at the top of auto-generated C files.	Joshua Haberman

2009-07-23	upb is fully self-hosting (except for text->descriptor)!	Joshua Haberman

2009-07-23	Make the compiler correctly define the top-level extern symbol.	Joshua Haberman

2009-07-22	Compiler finally works (except string arrays). Untested. Holy crap that ↵	Joshua Haberman
	was a lot of work.
2009-07-22	More work on the compiler.	Joshua Haberman

2009-07-21	More work on the compiler.	Joshua Haberman
