Josh Haberman	7d3e2bd2c4	Sync with 8 months of Google-internal development. Many things have changed and been simplified. The memory-management story for upb_def and upb_handlers is much more robust; upb_def and upb_handlers should be fairly stable interfaces now. There is still much work to do for the runtime component (upb_sink).	12 years ago
Joshua Haberman	9a7037a2fa	Got decoder & textprinter compiling in kernel mode.	13 years ago
Joshua Haberman	621c0cdcb5	Const invasion: large parts of upb made const-correct.	13 years ago
Joshua Haberman	10265aa56b	Directory restructure. 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).	14 years ago
Joshua Haberman	3231fd0fdd	Vastly improved/simplified the upb_handlers API.	14 years ago
Joshua Haberman	eb622c0531	Split upb_stream -> upb_bytestream/upb_handlers.	14 years ago
Josh Haberman	b796c1b317	Update copyright to be Google Inc. This doesn't reflect any material change in how I will be working on upb, and I have no problem making this change. It's still open source under the BSD license, and I'll still be working on it well beyond the hours that constitute a normal job.	14 years ago
Josh Haberman	8ef6873e0e	upb_stream: all callbacks registered ahead-of-time. This is a significant change to the upb_stream protocol, and should hopefully be the last significant change. All callbacks are now registered ahead-of-time instead of having delegated callbacks registered at runtime, which makes it much easier to aggressively optimize ahead-of-time (like with a JIT). Other impacts of this change: - You no longer need to have loaded descriptor.proto as a upb_def to load other descriptors! This means the special-case code we used for bootstrapping is no longer necessary, and we no longer need to link the descriptor for descriptor.proto into upb. - A client can now register any upb_value as what will be delivered to their value callback, not just a upb_fielddef*. This should allow for other clients to get more bang out of the streaming decoder. This change unfortunately causes a bit of a performance regression -- I think largely due to highly suboptimal code that GCC generates when structs are returned by value. See: http://blog.reverberate.org/2011/03/19/when-a-compilers-slow-code-actually-bites-you/ On the other hand, once we have a JIT this should no longer matter.

Joshua Haberman	6bdbb45e88	Merged core/ and stream/ -> src/. The split wasn't worth it.	14 years ago
Joshua Haberman	d98db7cb56	Textprinter is compiling again.	14 years ago
Joshua Haberman	2c24cbb108	More work on decoder and stdio bytesrc/bytesink.	14 years ago
Joshua Haberman	87b2c69c15	Fleshed out upb_stdio and upb_textprinter. test_decoder now compiles and links! But it doesn't work yet.	15 years ago
