"""
Build distribution packages for all architectures and all supported
python versions.
Usage:
build_distrib.py VERSION [--no-run-examples] [--no-rebuild]
Options:
VERSION Version number eg. 50.0
--no-run-examples Do not run examples while building cefpython modules.
Examples require interaction, closing window before
proceeding. Only unit tests will be run in such case.
--no-rebuild Do not rebuild cefpython modules. For internal use
so that changes to packaging can be quickly tested.
--no-automate Do not run automate.py --prebuilt-cef. This flag
allows to use CEF prebuilt binaries and libraries
downloaded from CEF Python's Github releases to
build distribution pacakges.
This script does the following:
1. Expects that all supported python versions are installed
a) On Windows search for Pythons in the multiple default install
locations
b) On Linux use only Pythons from ~/.pyenv/versions/
directory
c) On Mac use Pythons from ~/.pyenv/versions/ and /usr/local/bin/python
For example will use Python 2.7.13 from /usr/local/bin/ only
when 2.7 was not found in ~/.pyenv/versions/.
2. Expects that all python compilers for supported python versions
are installed. See docs/Build-instructions.md > Requirements.
3. Expects cef_binary*/ directories from Spotify Automated Builds
to be in the build/ directory. It does not rebuild cefclient
nor libcef_dll_wrapper libraries in these directories. If you
would like to rebuild everything from scratch then delete subdirs
manually (build_cefclient/, build_wrapper*/).
When building CEF from sources copy build/chromium/src/cef/binary_distrib
/cef_binary_*/ to the build/ directory.
4. Install and/or upgrade tools/requirements.txt and uninstall
cefpython3 packages for all python versions
5. Run automate.py --prebuilt-cef using both Python 32-bit and Python 64-bit
6. Pack the prebuilt biaries using zip on Win/Mac and .tar.gz on Linux
and move to build/distrib/
7. Reduce packages size (Issue #321). After packing prebuilt binaries,
reduce its size so that packages will use the reduced prebuilt binaries.
8. Build cefpython modules for all supported Python versions on both
32-bit and 64-bit. Backup and restore subprocess executable on Windows
built with Python 2.7 (Issue #342).
9. Make setup installers and pack them to zip (Win/Mac) or .tar.gz (Linux)
10. Make wheel packages
11. Move setup and wheel packages to the build/distrib/ directory
12. Test wheel packages installation and run unit tests using the
installed wheel package.
13. Show summary
