This allows replacing the C99 standard include file names with
a single system-specific file. It should provide all the necessary
system functions (typedefs, memset, memcpy, strlen).
Update issue 62
Status: FixedInGit
This is a more logical name in parallel with PB_HTYPE_REQUIRED and PB_HTYPE_OPTIONAL.
Warning: This breaks backwards-compatibility of generated .pb.c files.
You will have to regenerate the files and recompile.
This allows slight optimizations if only memory buffer support
(as opposed to stream callbacks) is wanted. On ARM difference
is -12% execution time, -4% code size when enabled.
This avoids doing 64-bit arithmetic for 32-bit varint decodings.
It does increase the code size somewhat.
Results for ARM Cortex-M3: -10% execution time, +1% code size, -2% ram usage.
In the pb_istream_from_buffer and pb_ostream_from_buffer, memcpy was
used to transfer values to the buffer. For the common case of
count = 1-10 bytes, a simple loop is faster.
Rationale: it's easy to implement the callback wrong. Doing so introduces
io errors when unknown fields are present in the input. If code is not
tested with unknown fields, these bugs can remain hidden for long time.
Added a special case for the memory buffer stream, where it gives a small
speed benefit.
Added testcase for skipping fields with test_decode2 implementation.
Update issue 37
Status: FixedInGit
This avoids double initialization when decoding nested submessages.
Fixes an issue with submessage arrays that was present in previous
version of this patch.
Update issue 28
Status: FixedInGit
This reverts commit dc2da0edc5.
Add pb_close_string_substream() for copying back the state.
This makes adding error messages easier in the future, as also
them need to be propagated back from the substream.
This makes the field decoding functions more intuitive to use.
The old interface is still present if you specify NANOPB_INTERNALS.
Update issue 2
Status: FixedInGit
This makes it unnecessary to copy back the state, and also relaxes
the requirements on callbacks (bytes_left will always be valid).
It decreases code size by a few bytes, but may be just slightly slower.
Main code is now compiled (for tests) with -pedantic -Wextra.
The test programs are not as strictly bound, but this should
improve the chances that atleast the core library compiles with
most compilers without warnings.
Now the limit of tracked fields is configurable at compile-time using
PB_MAX_REQUIRED_FIELDS. Added related test and updated documentation.
Fixes issue #18.
The size of non-callback bytes-fields was miscalculated, which
caused all following fields in a message to contain garbage.
Previous commit contains a testcase for this.
This fix changes the generated message description. If your protocol uses
bytes-fields, you should regenerate *.pb.c.
On big endian machines, pb_dec_fixed32 and pb_dec_fixed64 were
incorrectly overwriting the result value even if reading failed.

Most importantly, callback fields in submessages were being overwritten with garbage, causing segfaults.
Additionally, converted PB_LTYPE_FIXED to PB_LTYPE_FIXED32 and PB_LTYPE_FIXED64. This makes the interface
a bit easier to use, and in addition runs faster.
