# Therefore upb cannot be packaged for Fedora, and we must use the bundled

# copy.

#

# Note that upstream has never chosen a version, and it is not clear from which

# commit the bundled copy was taken or forked.

#

# Note also that libupb is installed in the system-wide linker path, which will

# be a problem if upb is ever packaged separately. We will cross that bridge if

# we get there.

Provides:       bundled(upb)

# The bundled upb itself bundles https://github.com/cyb70289/utf8; we follow

# upstream in styling this as “utf8_range”. It cannot reasonably be unbundled

# because the original code is not structured for distribution as a library (it

# does not even include header files). It is not clear which upstream commit

# was used.

Provides:       bundled(utf8_range)

# Regarding third_party/address_sorting: this looks a bit like a bundled

# library, but it is not. From a source file comment:

#   This is an adaptation of Android's implementation of RFC 6724 (in Android’s

#   getaddrinfo.c). It has some cosmetic differences from Android’s

#   getaddrinfo.c, but Android’s getaddrinfo.c was used as a guide or example

#   of a way to implement the RFC 6724 spec when this was written.

%description

gRPC is a modern open source high performance RPC framework that can run in any

environment. It can efficiently connect services in and across data centers

with pluggable support for load balancing, tracing, health checking and

authentication. It is also applicable in last mile of distributed computing to

connect devices, mobile applications and browsers to backend services.

The main usage scenarios:

  • Efficiently connecting polyglot services in microservices style

    architecture

  • Connecting mobile devices, browser clients to backend services

  • Generating efficient client libraries

Core Features that make it awesome:

  • Idiomatic client libraries in 10 languages

  • Highly efficient on wire and with a simple service definition framework

  • Bi-directional streaming with http/2 based transport

  • Pluggable auth, tracing, load balancing and health checking

This package provides the shared C core library.

gRPC Python Admin Interface Package

===================================

Debugging gRPC library can be a complex task. There are many configurations and

internal states, which will affect the behavior of the library. This Python

package will be the collection of admin services that are exposing debug

information. Currently, it includes:

* Channel tracing metrics (grpcio-channelz)

* Client Status Discovery Service (grpcio-csds)

Here is a snippet to create an admin server on "localhost:50051":

    server = grpc.server(ThreadPoolExecutor())

    port = server.add_insecure_port('localhost:50051')

    grpc_admin.add_admin_servicers(self._server)

    server.start()

Welcome to explore the admin services with CLI tool "grpcdebug":

# Patch CMakeLists for external gtest/gmock.

#

#  1. Create dummy sources, adding a typedef so the translation unit is not

#     empty, rather than removing references to these sources from

#     CMakeLists.txt. This is so that we do not end up with executables with no

#     sources, only libraries, which is a CMake error.

#  2. Either remove references to the corresponding include directories, or

#     create the directories and leave them empty.

#  3. “Stuff” the external library into the target_link_libraries() for each

#     test by noting that GMock/GTest/GFlags are always used together.
