- Added a JSON test that round-trips (parses then re-serializes) several
test messages, ensuring that the re-serialized form matches the
original exactly.
- Added support for printing and parsing symbolic enum names (rather than
integer values) in JSON.
- Updated JSON printer to properly handle string fields that come in
multiple pieces. ('bytes' fields still do not support this, and this
work is more challenging because it requires making the base64 encoder
resumable. Base64 encoding is not separable at an input-byte
granularity, unlike string escaping.)
- Fixed a < vs. <= bug in UTF-8 encoding generation (oops).

Most notably, a JSON parser is now provided.

This avoids requiring protoc to be installed
just to build/run the basic tests.
When upb has its own .proto file parser we should
be able to remove this precompiled version from the
repository.

Notable changes:
- We now only build things by default that require
no dependencies. So you can build upb even if you
don't have Lua or Google protobuf installed.
- Checked in a pre-built version of the JIT, so you
don't need Lua installed at build time to run DynASM.
It will still notice if you change the .dasc file and
attempt to re-run DynASM in that case.
- The build system now builds all modules of upb into
separate libraries, reflecting the modularity that
is already inherent in upb's design. This should
make it easier to trim the fat.
- removed the GDB JIT interface. I wasn't using it
much; using a .so is easier and more robust.

- rewritten decoder; interpreted decoder is bytecode-based,
JIT decoder no longer falls back to the interpreter.
- C++ improvements: C++11-compatible iterators, upb::reffed_ptr
for RAII refcounting, better upcast/downcast support.
- removed the gross upb_value abstraction from public upb.h.
|

|
|
- Better error reporting for upb::Def setters.
- error reporting for upb::Handlers setters.
- made the start/endmsg handlers a little less special-cased.
|
|
C++ handlers are now type-safe; SinkFrame is gone.
Various other changes.
|
|
Major changes:
- Got rid of all bytestream interfaces in favor of
using regular handlers.
- new Pipeline object represents a upb pipeline, does
bump allocation internally to manage memory.
- proto2 support now can handle extensions.
|
|
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).

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.

This breaks the open-source build, will
follow up with a change to fix it.

Added a upb_byteregion that tracks a region of
the input buffer; decoders use this instead of
using a upb_bytesrc directly. upb_byteregion
is also used as the way of passing a string to
a upb_handlers callback. This symmetry makes
decoders compose better; if you want to take
a parsed string and decode it as something else,
you can take the string directly from the callback
and feed it as input to another parser.
A commented-out version of a pinning interface
is present; I decline to actually implement it
(and accept its extra complexity) until/unless
it is clear that it is actually a win. But it
is included as a proof-of-concept, to show that
it fits well with the existing interface.

This might actually just bring to light my misuse of the upb_fielddef
functions. The test assertions are fine, but an assertion in upb/upb.h
fails:
./upb/upb.h:181: upb_value_getptr: Assertion `val.type == 33' failed.

This type was nothing but a map of defs.
We can as easily just pass an array of defs
into upb_symtab_add().
|
|
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).
|
|
|
|
Next on the chopping block is upb_string.
|
|
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
|

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: [].
|
|
Now the dispatcher will call error handlers
instaed of returning statuses that the caller
has to constantly check.
