# A shared object which includes registration mechanisms for ops and
# kernels. Does not include the implementations of any ops or kernels. Instead,
# the library which loads libtensorflow_framework.so
# (e.g. _pywrap_tensorflow_internal.so for Python, libtensorflow.so for the C
# API) is responsible for registering ops with libtensorflow_framework.so. In
# addition to this core set of ops, user libraries which are loaded (via
# TF_LoadLibrary/tf.load_op_library) register their ops and kernels with this
# shared object directly.
#
# For example, from Python tf.load_op_library loads a custom op library (via
# dlopen() on Linux), the library finds libtensorflow_framework.so (no
# filesystem search takes place, since libtensorflow_framework.so has already
# been loaded by pywrap_tensorflow) and registers its ops and kernels via
# REGISTER_OP and REGISTER_KERNEL_BUILDER (which use symbols from
# libtensorflow_framework.so), and pywrap_tensorflow can then use these
# ops. Since other languages use the same libtensorflow_framework.so, op
# libraries are language agnostic.
#
# This shared object is not used unless framework_shared_object=true (set in the
# configure script unconditionally); otherwise if it is false or undefined, the
# build is static and TensorFlow symbols (in Python only) are loaded into the
# global symbol table in order to support op registration. This means that
# projects building with Bazel and importing TensorFlow as a dependency will not
# depend on libtensorflow_framework.so unless they opt in.
#
# DEBUGGING DUPLICATE INITIALIZATION
# ----------------------------------
#
# Having a dynamic library introduces a diamond dependency problem:
# if a target X is depended on by both libtensorflow_framework.so and the
# users of libtensorflow_framework.so, the definitions will get duplicated.
# This causes global initializers which need to be run exactly once (e.g.
# protobuf registration) to crash, as the initialization is run once from the
# statically linked in global, and one by the global which comes in from
# libtensorflow_framework.so.
# Even worse, global objects which need to be singletons for semantical
# correctness (e.g. registers) might get duplicated.
#
# In order to avoid these HARD TO DEBUG CRASHES, it is sufficient to follow
# these rules:
#  - All globals with non-trivial static constructors or for which a
#    single identity is required (e.g. registers) need to live in `*_impl`
#    targets.
#
#  - An `*_impl` target has to be (transitively) included into
#    `libtensorflow_framework.so`.
#
#  - A target T1 can depend on `*_impl` target T2 only if:
#
#    -> It's a tf_cc_shared_object, and there is no other tf_cc_shared_object
#       transitively depending on T2.
#    -> It's an `*_impl` target by itself
#    -> The dependency is guarded by `if_static`. This is discouraged,
#       as it diverges dependency topology between static and dynamic TF.
#
