upb previously attempted to support C89 and pre-2015 versions
of Visual Studio. This was to support older compilers with
limited C99 support (particularly MSVC). But as of last August,
even gRPC has dropped support for MSVC prior to 2015
c87276d058
Therefore it seems safe for upb to no longer attempt C89 support
(we were already not truly C89 compliant, with our use of "bool").
We now explicitly require C99 or greater and MSVC 2015 or greater.
This cleaned up port_def.inc a fair bit. I took the chance to
also remove some obsolete macros.
* Added -Wextra and -Wshorten-64-to-32 and fixed resulting errors.
* Disable -Wshorten-32-to-64 since Kokoro is missing Clang.
* Fixed -Wextra warnings for gcc.
* Reordered UPB_UNUSED() to come after declarations.
* Added another -pedantic fix and log CC version.
* Fix compile error and conditionally run use_bazel.sh.
* Moved set -e after use_bazel.sh.
* Fixed typo in conditional.
* Simplified epoch day algorithm.
* A nicer version that divides by 2048, thanks to Gerben. for the suggestion.
* A little less cleverness, for the sake of readability.
* A bit more tweaking for readability.
* Updated CMake copy.
* Add tests for proto2
* Fix ignore unknown enum value
* Fix CheckConsistency
* Add note to mention clear field for unknown enum value
* Update Comment
* Fix generated test
* Fix generated test
* Added support for proto3 optional to defs.
* Added proto3 optional support. Untested at the moment.
* Changes to support proto3 optional.
* Fixed real oneof count for messages with no fields.
* Fixed compile error and test.
* Added comment about why I'm commenting out the assert.
* Removed reflection and other extraneous things from the core library.
* Added missing files and ran buildifier.
* New CMakeLists.txt.
* Made table its own cc_library() for internal usage.
* Implement json decoding for Any message.
type url may not appear as the first value in json. As a result,
other data cannot be resolved before resolving type url. To solve that,
this change caches the start and end position of unparsed values and
resolve them in end_any_object when type url has been resolved.
* Handle Any in switch
* Update json parser size
* Fix comments
* Sync upstream
* Add dependency on upb_pb for upb_json
* Debug failed test
* Fix cmake
* Update test generated files
* Remove debug tests
* Fix json ignore unknown
Previously, there were several problems with ignoring unknown in json.
1) After finding a field is unknown, the parser's state is not changed. Thus, there is no way to distinguish whether the parser is dealing with an unknown field or it's just a top level message.
2) Several method didn't respect unknown field, e.g., start_object, end_bool, start_array.
* Update json parser size
* Update json parser size
* Fix json encoding for wrappers, ListValue, Struct and Value.
* Add well_known_type field in upb_msgdef to specify type of well known messages.
* Remove comma at end of enum definition.
* Group number wrappers
* Fix comments
* Refactoring to use is_wellknown_{msg/field}
