Jacob Alexander 313d0d4c6d Prepare for v2.0.0b1 release
- Update CHANGELOG.md
- Update to bundled capnproto-1.0.1
  * Compiles with capnproto-0.8.0 and higher
- *Breaking Change* Remove allow_cancellation (see
  https://capnproto.org/news/2023-07-28-capnproto-1.0.html)
  * This is tricky to handle for older versions of capnproto. Instead of
    dealing with lots of complication, removing it entirely.
- Fix some documentation after the build backend support was added
- Update tox.ini to support 3.8 to 3.12
- Update cibuildwheel to 2.16.1
  * Adds Python 3.12 supports and implicitly deprecates EOL 3.7 (though it's
    still built)

Installation
============
Pip
---
The pip installation will using the binary versions of the package (if possible). These contain a bundled version of capnproto (on Linux compiled with `manylinux <https://github.com/pypa/manylinux>`_). Starting from v1.0.0b1 binary releases are available for Windows, macOS and Linux from `pypi <https://pypi.org/project/pycapnp/#history>`_::
[sudo] pip install pycapnp
To force rebuilding the pip package from source (you'll need requirments.txt or pipenv)::
pip install --no-binary :all: pycapnp
To force bundling libcapnp (or force system libcapnp), just in case pip isn't doing the right thing::
pip install --no-binary :all: -C force-bundled-libcapnp=True
pip install --no-binary :all: -C force-system-libcapnp=True
If you're using an older Linux distro (e.g. CentOS 6) you many need to set `LDFLAGS="-Wl,--no-as-needed -lrt"`::
LDFLAGS="-Wl,--no-as-needed -lrt" pip install --no-binary :all: pycapnp
It's also possible to specify the libcapnp url when bundling (this may not work, there be dragons)::
pip install --no-binary :all: -C force-bundled-libcapnp=True -C libcapnp-url="https://github.com/capnproto/capnproto/archive/master.tar.gz"
From Source
-----------
Source installation is generally not needed unless you're looking into an issue with capnproto or pycapnp itself.
C++ Cap'n Proto Library
~~~~~~~~~~~~~~~~~~~~~~~
You need to install the C++ Cap'n Proto library first. It requires a C++ compiler with C++14 support, such as GCC 5+ or Clang 5+. Follow installation docs at `https://capnproto.org/install.html <https://capnproto.org/install.html>`_.

If you want the latest development version, you can clone the github repo::
git clone https://github.com/capnproto/pycapnp.git
For development packages use one of the following to install the python dependencies::
pipenv install
pip install -r requirements.txt
And install pycapnp with::
cd pycapnp
pip install .
Development

Clone the repo from https://github.com/capnproto/pycapnp.git::
git clone https://github.com/capnproto/pycapnp.git
For development packages use one of the following to install the python dependencies::

pip install -r requirements.txt
Building::
cd pycapnp
pip install .
Useful targets for setup.py::
python setup.py clean
Useful command-line arguments are available for pip install::
-C force-bundled-libcapnp=True
-C force-system-libcapnp=True
-C libcapnp-url="https://github.com/capnproto/capnproto/archive/master.tar.gz"
Testing is done through pytest::
cd pycapnp
pytest
pytest test/test_rpc_calculator.py
