# Upstream https://github.com/protocolbuffers/upb does not support building

# Monitor this at https://bugzilla.redhat.com/show_bug.cgi?id=1470842.
# 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)

# 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.

%changelog
* Sun Mar 21 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 1.26.0-13
- General:
  * Replace * with • in descriptions
  * Use cmake() dependencies first, and pkgconfig() dependencies second, where
    available
  * Drop explicit pkgconfig BR
  * Fix the directory in which CMake installs pkgconfig files
  * Improved CMake options
- C (core) and C++ (cpp):
  * Let the -devel package require cmake-filesystem
  * Allow building tests with our own copy of gtest/gmock, which will become
    mandatory when we depend on abseil-cpp and switch to C++17
  * Fix a link error in the core tests when using CMake
  * Manually install grpc_cli (CMake)
  * Add CMake files to the files list for the -devel package
- Python:
  * Add several patches required for the tests
  * BR gevent for gevent_tests
  * Fix build; in particular, add missing preprocess and build_package_protos
    steps, without which the packages were missing generated proto modules and
    were not
    usable!
  * Add %%py_provides for Fedora 32
  * Drop python3dist(setuptools) BR, redundant with %%pyproject_buildrequires
  * Start running most of the tests in %%check

* Tue Feb 16 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 1.26.0-12
- C (core) and C++ (cpp):
  * Add CMake build support but do not enable it yet; there is still a problem
    where grpc_cli is only built with the tests, and a linking problem when
    building the tests

* Tue Feb 02 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 1.26.0-11
- General:
  * Update summaries and descriptions
  * Update License fields to include licenses from bundled components
  * Fix failure to respect Fedora build flags
  * Use the system shared certificate bundle instead of shipping our own
- CLI:
  * No longer set rpath $ORIGIN
- C (core) and C++ (cpp):
  * Add c_so_version/cpp_so_version macros
  * Split out C++ bindings and shared data into subpackages
  * Drop obsolete ldconfig_scriptlets macro
  * Stop stripping debugging symbols
- Python:
  * Use generated BR’s
  * Build and package Python binding documentation
  * Disable accommodations for older libc’s
  * Patch out -std=gnu99 flag, which is inappropriate for C++
  * Build additional Python packages grpcio_tools, gprcio_channelz,
    grpcio_health_checking, grpcio_reflection, grpcio_status, and
    grpcio_testing
