protobuf-c/ChangeLog

protobuf-c (1.0.0) UNRELEASED

  [ Dave Benson ]
  * Treat a "length-prefixed" wire-type message for a repeated field as
    packed-repeated whenever it makes sense (for all types other than
    messages, strings, and bytes).

  * Switch to New BSD license.

  * Add protobuf_c_message_check().

  * Compile error in packing 64-bit versions on some platforms
    (srobbins99: Issue #68 Comment 1).

  * Fix for memory error if the required-field check fails. See Issue #63
    for demo (w/ nice test case by dror.harari).

  * Add PROTOBUF_C_{MAJOR,MINOR} for compile-time checks and
    protobuf_c_{major,minor} for checks about the running library
    (Issue #53).

  * Use a small constant-size hash-table instead of alloca() for detecting
    required fields, and it also prevents us from using too much stack, etc.
    (Related to Issue #60, #79).

  * Add a macro to ensure enums are the size of ints (Issue #69).

  [ Ilya Lipnitskiy ]
  * Travis-CI integration.

  * Add source .proto filename to generated files.

  * Add protobuf-c version to protoc-c --version output (Issue #52).

  * For embedded submessage fields, merge multiple instances of the same
    field, per the protobuf documentation (Issue #91).

  * Don't print unpack errors by default.

  * Optionally allow running the test suite under valgrind with ./configure
    --enable-valgrind-tests. (Based on valgrind-tests.m4 from gnulib.)

  [Kevin Lyda]
  * Autoconf portability fixes.

  * Add doxygen detection and make targets to the build system.

  [Nick Galbreath]
  * Prevent possible overflow on 64-bit systems (Issue #106).

  [ Robert Edmonds ]
  * Remove CMake (Issue #87).

  * Modernize the build system.
    - Don't generate any diagnostics when building the build system with
      modern autotools (Issue #89).

    - Use the PKG_CHECK_MODULES macro to locate protobuf.

    - Use the AC_C_BIGENDIAN macro to detect endianness, rather than custom
      code.

    - Use the automake silent-rules option so the build output is actually
      readable.

    - Generate our own pkg-config .pc files.

  * Reorganize the source tree. This affects the public protobuf-c header
    path, which is now <protobuf-c/protobuf-c.h>. A compatibility symlink from
    <google/protobuf-c/> to <protobuf-c/> has been installed so that existing
    code will continue to compile. New code should at some point begin using
    the new include path, i.e., "#include <protobuf-c/protobuf-c.h>" rather
    than "#include <google/protobuf-c/protobuf-c.h>".

  * The RPC code has been split out into a separate project, protobuf-c-rpc.

  * Fix a potential use of an unitialized value in protobuf_c_message_unpack()
    and several memory leaks in protoc-c, discovered by a commercial static code
    analysis tool.

  * Bump the libprotobuf-c SONAME.

  * Begin versioning the library's symbols. (Based on ld-version-script.m4
    from gnulib.)

  * Preserve case in enum value names generated by protoc-c (Issue #129).
    Reported by Oleg Efimov.

  * Update copyright and license statements throughout. The original
    protobuf code released by Google was relicensed from Apache-2.0 to
    BSD-3-Clause. Dave Benson also converted his license from BSD-3-Clause
    to BSD-2-Clause.

  [Tomasz Wasilczyk]
  * Don't export protobuf_c_message_init_generic() as an external symbol.

  * Don't use C++ style comments in C code.

  * Fix -Wcast-align warnings when compiled with clang.

      - add generation / installation of pkg-config files. (Bobby Powers)
      - support for packed repeated fields (Dave Benson)
      - bug in protobuf_c_dispatch_close_fd(), which usually only
        showed up in later function calls.
      - support for deprecated fields -- enable a GCC warning
        if a field has the "deprecated" option enabled. (Andrei Nigmatulin)
      - hackery to try to avoid touching inttypes.h on windows (Issue #41)
      - fix for protobuf_c_message_unpack() to issue error if any
        "required" field is missing in input stream. (Andrei Nigmatulin)

protobuf-c (0.13)
      - Fix for when the number of connections gets too great in RPC.
        (Leszek Swirski) (issue #32)
      - Add --disable-protoc to only build libprotobuf-c (daveb)
      - Bug fixes for protobuf_c_enum_descriptor_get_value_by_name()
        and protobuf_c_service_descriptor_get_method_by_name()
      - if descriptor->message_init != NULL, use it from unpack()
        as an optimization (daveb)
      - implement protobuf_c_{client,server}_set_error_handler()

protobuf-c (0.12)
      - for field names which are reserved words, use the real name
        given in the protobuf-c file, not the mangled name which
        is the name of the member in the C structure.  (Andrei Nigmatulin)
      - add protobuf_c_message_init() function; add virtual function
        that implements it efficiently.  (Andrei Nigmatulin)
      - bug fix for sfixed32, fixed32, float wire-types on
        big-endian platforms (Robert Edmonds)
      - compile with the latest protobuf (the header file wire_format_inl.h
        is now wire_format.h) (Robert Edmonds)

protobuf-c (0.11)
      - allow CFLAGS=-DPRINT_UNPACK_ERRORS=0 to suppress
        unpack warnings from being printed at compile time (Andrei Nigmatulin)
      - give error if an unknown wire-type is encountered (Andrei Nigmatulin)
      - fix technically possible overflows during unpack of very
        large messages (Andrei Nigmatulin)
      - [UNFINISHED] windows RPC work
      - use automake's "foreign" mode from within configure.ac
        and add version information to the library (Robert Edmonds)
      - ProtobufCServiceDescriptor::method_indices_by_name:  missing
        const.  (Issue 21)
      - Update to support new UnknownFields API.  (fix by dcreager) (Issue 20)

protobuf-c (0.10)
      - build issue on platforms which don't compute library dependencies
        automatically.
      - fix for certain types of corrupt messages (Landon Fuller) (issue 16)

protobuf-c (0.9)
      - build issue: needed $(EXEEXT) in dependency lists for cygwin
      - bug fix:  protobuf_c_service_get_method_by_name() was not correct b/c
        the service's methods were not sorted by name (the header file
        used to incorrectly state that they were).
        Now we correctly implement protobuf_c_service_get_method_by_name()
        (using a bsearch indexed by separate array).
      - generated source incompatibility:  we added a new
        member to ProtobufCServiceDescriptor (method_indices_by_name).
        You will have to run the latest protobuf
        to generate those structures.
      - rename rpc-client's "autoretry" mechanism to "autoreconnect".
      - bug fixes using TCP clients with the RPC system.
      - handle allocation failures more gracefully (Jason Lunz) (issue 15)

      - Destroy function typedef for Services was omitting a "*"
      - service_machgen_invoke was broken. (issue 12)
      - add RPC system (BETA)
      - don't segfault when packing NULL strings and messages. (issue 13)

protobuf-c (0.7)
      - memory leak:  unknown fields were not being freed by free_unpacked()
      - lowercase field names consistently when composing
        default_value names. (issue 11)
      - remove spurious semicolon (issue 10)

protobuf-c (0.6)
      - Warning suppression for -Wcast-qual and -Wshadow.
      - Support for default values of all types allowed by core protobuf.
      - Generate message__init functions, for when the static initializer
        isn't convenient.
      - add some reserved fields at the end of the various descriptors
