* objectivec: Quash -Wself-assign
* objectivec: Set -Wno-vla when building
Objective-C protobuf uses VLAs for performance reasons. Ensure Clang
doesn’t complain about them.
This change reduces the excessive warnings when compiling C++ protobufs like "external/protobuf_archive/python/google/protobuf/pyext/message.cc:2629:1: warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings]"
`python/google/__init__.py` declares the top-level 'google' namespace so that
`google.protobuf` can be imported alongside other Google Python modules like
`google.auth`.
This works well when installing protobuf via Pip, but the Bazel `//:python_srcs`
rule doesn't include this file in its `srcs`. Bazel implicitly creates an empty
`google/__init__.py`, which does *not* set up a namespace. The result is that
consuming Python protobuf via Bazel breaks all other Google Python libraries.
This fixes#4658.
@com_google_protobuf prefixed versions. This allows them to work in 3rd party
repositories.
Fix a bad visibility rule. :hidden does not exist, but :private does.
This prevents the Bazel `CcProtoAspect` from generating and linking
C++ object code for these files. Without this blacklist, symbols for
protobuf types depended on by `libprotobuf` may be defined multiple
times and violate the ODR rule.
Fixes https://github.com/google/protobuf/issues/4311
Fixes: #4256.
Bazel@HEAD supports Java 9.
The current code has one single issue with Java 9 compliance: the usage
of sun.misc package. We add jdk.unsupported module with --add-modules
compiler option for now. Long term, the usage of non public API should
be avoided.
To build with Java 9, build custom bazel version and issue:
$ bazel --host_javabase=/usr/lib64/jvm/java-9-openjdk build \
--javacopt='--release 9' \
--java_toolchain=@bazel_tools//tools/jdk:toolchain_jdk9 \
:protobuf_java
-Wno-writable-strings removes 230 "ISO C++11 does not allow conversion from
string literal to 'char *'" warnings from TensorFlow test / build output.
These happen because pyext/ sources pass string literals to Python C API data
structures, e.g. PyGetSetDef, which for some reason were designed to not have
the const qualifier.
The SDK and os versions were hard coded. Archs were mixed up.
Because of this, Was getting errors with latest SDK:

Currently none of these are needed when using bazel with https://github.com/bazelbuild/rules_apple.
-target arm64-apple-ios is passed properly to clang. So -arch armv7 etc are not needed.
OS_IOS is not used anywhere.
Sources have: GOOGLE_PROTOBUF_NO_THREADLOCAL defined in src/google/protobuf/stubs/platform_macros.h for iOS. So __thread= is not needed. In fact now that bazel is using C++11 by default, __thread should ideally be moved to thread_local.
-miphoneos-version-min is passed by rules_apple.
Adds a proto_library rule for each well known type proto:
$ bazel query "filter(\".*_proto$\", \"...\")"
//:wrappers_proto
//:timestamp_proto
//:struct_proto
//:field_mask_proto
//:empty_proto
//:duration_proto
//:compiler_plugin_proto
//:descriptor_proto
//:api_proto
//:type_proto
//:source_context_proto
//:any_proto
Bazel users can reference these proto_library rules for their own
language specific rules i.e.
java_proto_library(
name = "any_java_proto",
deps = ["@com_google_protobuf//:any_proto"],
)
Also set the workspace name to "com_google_protobuf", as proto_library
rules reference protobuf that way.
