upb.git - a small protobuf implementation in C

Age	Commit message (Collapse)	Author
2011-08-22	Add comment clarifying that the proto2 benchmark is ugly and temporary.	Joshua Haberman

2011-08-21	Some progress on upb_stdio.	Josh Haberman
	It's still not correct, but it's closer.
2011-08-20	Fold gen-deps.sh into Makefile.	Joshua Haberman

2011-08-20	Let the JIT emit hasbit-setting code in addition to calling a callback.	Joshua Haberman
	This leads to a major (20-40%) improvement in the parsetoproto2 benchmark with small messages. We now are faster than proto2 in all apples-to-apples comparisons, at least given the (admittedly limited) set of benchmarks in this source tree.
2011-08-20	Fix stack alignment on OS X.	Joshua Haberman

2011-08-20	Prime the decoder buf for modest perf improvement on small messages.	Joshua Haberman

2011-08-19	Renamed lang_ext -> bindings, README updates.	Joshua Haberman

2011-08-19	Avoid longjmp() in successful case.	Josh Haberman
	Speeds up short messages by 15-25%.
2011-08-19	Fix proto2 benchmark for newer proto2.	Josh Haberman

2011-08-19	Benchmark to parse into proto2 messages.	Joshua Haberman

2011-08-17	x86 JIT: add callback specializations for a 10% speedup when parsing to struct.	Joshua Haberman

2011-08-17	Benchmark JIT vs no JIT without forcing a whole-project recompile.	Joshua Haberman

2011-08-12	Python: fleshed out accessors.	Joshua Haberman

2011-08-12	Python: basic SymbolTable support and empty accessors.	Joshua Haberman

2011-08-11	Python: fixed object cache and fleshed out MessageDef a bit.	Joshua Haberman

2011-08-10	Fixed overzealous assert().	Joshua Haberman

2011-08-10	Fixed a few memory leaks and Makefile tweaks.	Joshua Haberman

2011-08-10	Fixed off-by-one stack allocation error.	Joshua Haberman

2011-08-10	Python: Implemented weak-ref'd object cache.	Joshua Haberman
	Also some preliminary work on upb.MessageDef.
2011-08-09	Makefile target for running Python tests.	Joshua Haberman

2011-08-09	More Python upb.FieldDef functionality and tests.	Joshua Haberman

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
