# Replace sphinxcontrib-asyncio, which is not working properly:
#   (Error in "py:comethod directive: unknown option: "async".):
# with sphinxcontrib-trio

BuildRequires:  gcc
BuildRequires:  python3-devel
BuildRequires:  pyproject-rpm-macros

BuildRequires:  python3-docs

BuildRequires:  make

# For tests:
#
# For pg_config binary
BuildRequires:  libpq-devel
# For pg_ctl binary
BuildRequires:  postgresql-server
# For citext extension
BuildRequires:  postgresql-contrib

# Note that asyncpg/pgproto comes from a git submodule referencing a separate
# project, https://github.com/MagicStack/py-pgproto. However, we do not treat
# it as a bundled dependency because it contains only sources; it has no build
# system and is not designed for separate installation; and it is managed as a
# part of the asyncpg package, as evidenced by the comment “This module is part
# of asyncpg” in the file headers.

%global common_description %{expand:
asyncpg is a database interface library designed specifically for PostgreSQL
and Python/asyncio. asyncpg is an efficient, clean implementation of PostgreSQL
server binary protocol for use with Python’s asyncio framework. You can read
more about asyncpg in an introductory blog post
http://magic.io/blog/asyncpg-1m-rows-from-postgres-to-python/.}
