Many classes within collections were moved to collections.abc in Python
3.3 -- their usage as imported directly from collections is now
deprecated as of Python 3.7 and will be removed soon.
The fallback import added in this PR can be removed entirely when
support for versions of Python prior to 3.3 is dropped.
1. Fix C++ tests.
* Add missing files to Makefile.am and fix distcheck in tests.sh
* Remove BUILT_SOURCES from conformance/Makefile.am.
* Add some missing override keyword.
* Add a type cast to int64 because our StrCat() in stubs can't handle size_t.
2. Fix Java tests.
* Add missing test dependency on guava in pom.xml.
* Include newly referenced test data in test resources.
* Manually fix map_lite_test.proto which is overwritten because it's mapped
from map_test.proto in google3.
* Add back "optimize_for = LITE_RUNTIME" which is still needed to keep the
opensource test passing as it's still running lite tests.
* Add a type cast in newBuilder() because without it the code doesn't compile
with openjdk javac 1.8 (the compiler can't figure if it's the right type
due to complex generic typing).
3. Fix Python tests.
* Remove/replace references to <hash_map>.
* Suppress more warnings in setup.py.
* Replace incorrect header inclusion for google/protobuf/proto_api.h.
* Add strings::EndsWith to google/protobuf/stubs/strutil.h because it's
referenced in the updated python C extension code.
* Replace proto2 with google::protobuf. The proto2 name is leaked to
opensource because we removed the subsitition rule for proto2 namespace
but only fixed C++ source code and forgot to update python C extension code.
Compilation of Python wrappers fails with Python 3.7 because
the Python folks changed their C API such that
PyUnicode_AsUTF8AndSize() now returns a const char* rather
than a char*. Add a patch to work around. Relates #4086.
The compiler and util subpackages are created by the build_py class in
setup.py. This has caused an issue in the protobuf package in
conda-forge (https://github.com/conda-forge/protobuf-feedstock/issues/40),
which is fixed by this commit.
Otherwise, pip complains "cannot find a version satisfies the
requirement." I suspect it was due to caching issues. I usued to
manually add a `sleep 30` between the upload and the installation test
which is quite unstable.
Add _file_desc_by_toplevel_extension back for compatibility issue with 3.4.1.
_file_desc_by_toplevel_extension is a temporary solution for FieldDescriptor.file.
FieldDescriptor.file was added in code gen. However, we need to keep it for some time for compatibility reason (with 3.4.1 only). May try to remove it after 2 years.
