# Notes from bootstraping Python 3.6

# ==================================

#

# New Python major version (3.X) break ABI and bytecode compatibility,

# so all packages depending on it need to be rebuilt.

#

# Due to a dependency cycle between Python, gdb, rpm, pip, setuptools, wheel,

# and other packages, this isn't straightforward.

# Build in the following order:

#

# 1. At the same time:

#     - gdb without python support (add %%global _without_python 1 on top of

#       gdb's SPEC file)

#     - python-rpm-generators with bootstrapping_python set to 1

#       (this can be done also during step 2., but should be done before 3.)

# 2. python3 without rewheel (use %%bcond_with rewheel instead of

#     %%bcond_without)

# 3. At the same time:

#     - gdb with python support (remove %%global _without_python 1 on top of

#       gdb's SPEC file)

#     - python-rpm-generators with bootstrapping_python set to 0

#       (this can be done at any later step without negative effects)

# 4. rpm

# 5. python-setuptools with bootstrap set to 1

# 6. python-pip with build_wheel set to 0

# 7. python-wheel with %%bcond_without bootstrap

# 8. python-setuptools with bootstrap set to 0 and also with_check set to 0

# 9. python-pip with build_wheel set to 1

# 10. pyparsing

# 11. python3 with rewheel

#

# Then the most important packages have to be built, in dependency order.

# These were:

#   python-sphinx, pytest, python-requests, cloud-init, dnf, anaconda, abrt

#

# After these have been built, a targeted rebuild should be done for the rest.

%description -n platform-python-debug

python3-debug provides a version of the Python runtime with numerous debugging

features enabled, aimed at advanced Python users such as developers of Python

extension modules.

This version uses more memory and will be slower than the regular Python build,

but is useful for tracking down reference-counting issues and other bugs.

The bytecode format is unchanged, so that .pyc files are compatible between

this and the standard version of Python, but the debugging features mean that

C/C++ extension modules are ABI-incompatible and must be built for each version

separately.

The debug build shares installation directories with the standard Python

runtime, so that .py and .pyc files can be shared.

Compiled extension modules use a special ABI flag ("d") in the filename,

so extensions for both versions can co-exist in the same directory.
