Move CPython C API from Include/fileutils.h into a new
Include/cpython/fileutils.h header file which is included by
Include/fileutils.h.
Exclude the following private symbols from the limited C API:
* _Py_error_handler
* _Py_GetErrorHandler()
* _Py_DecodeLocaleEx()
* _Py_EncodeLocaleEx()

Add Include/cpython/bytearrayobject.h and
Include/cpython/bytesobject.h header files.
Move CPython C API from Include/bytesobject.h into a new
Include/cpython/bytesobject.h header file which is included by
Include/bytesobject.h. Do a similar change for
Include/bytearrayobject.h.

Move the dtoa.h header file to the internal C API as pycore_dtoa.h:
it only contains private functions (prefixed by "_Py").
The math and cmath modules must now be compiled with the
Py_BUILD_CORE macro defined.
|
|
|
|
|

Move the bytes_methods.h header file to the internal C API as
pycore_bytes_methods.h: it only contains private symbols (prefixed by
"_Py"), except of the PyDoc_STRVAR_shared() macro.

This allows clang to get rid of the dependency on libgcov.
When linking, GCC passes -lgcov while clang passes the path to libclang_rt.profile-$arch.a

Provide Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() as
regular functions for the limited API. Previously, there were defined
as macros, but these macros didn't work with the limited API which
cannot access PyThreadState.recursion_depth field.
Remove _Py_CheckRecursionLimit from the stable ABI.
Add Include/cpython/ceval.h header file.

Change "clean" makefile target to also clean the program guided
optimization (PGO) data. Previously you would have to use "make

(GH-15757)
The missing dependencies prevented incremental builds from working when you touched any
of these files. Based on GH-14758 by @vemakereporter.

Reduce the number of unit tests run for the PGO generation task. This
speeds up the task by a factor of about 15x. Running the full unit test
suite is slow. This change may result in a slightly less optimized build
since not as many code branches will be executed. If you are willing to
wait for the much slower build, the old behavior can be restored using
'./configure [..] PROFILE_TASK="-m test --pgo-extended"'. We make no
guarantees as to which PGO task set produces a faster build. Users who
care should run their own relevant benchmarks as results can depend on
the environment, workload, and compiler tool chain.

To embed Python into an application, a new --embed option must be
passed to "python3-config --libs --embed" to get "-lpython3.8" (link
the application to libpython). To support both 3.8 and older, try
"python3-config --libs --embed" first and fallback to "python3-config
--libs" (without --embed) if the previous command fails.
Add a pkg-config "python-3.8-embed" module to embed Python into an
application: "pkg-config python-3.8-embed --libs" includes
"-lpython3.8". To support both 3.8 and older, try "pkg-config
python-X.Y-embed --libs" first and fallback to "pkg-config python-X.Y
--libs" (without --embed) if the previous command fails (replace
"X.Y" with the Python version).
On the other hand, "pkg-config python3.8 --libs" no longer contains
"-lpython3.8". C extensions must not be linked to libpython (except
on Android, case handled by the script); this change is backward
incompatible on purpose.
"make install" now also installs "python-3.8-embed.pc".

Misc/python-config.sh lives in the build directory, not in the source
directory.

Add PYTHONPATH=$(srcdir) to run $(PYTHON_FOR_REGEN) -m Parser.pgen,
so it's possible to build Python from a different directory.

On Unix, C extensions are no longer linked to libpython.
It is now possible to load a C extension built using a shared library
Python with a statically linked Python.
When Python is embedded, libpython must not be loaded with
RTLD_LOCAL, but RTLD_GLOBAL instead. Previously, using RTLD_LOCAL, it
was already not possible to load C extensions which were not linked
to libpython, like C extensions of the standard library built by the
"*shared*" section of Modules/Setup.
distutils, python-config and python-config.py have been modified.

After the removal of pgen, multiple header and function prototypes that lack implementation or are unused are still lying around.

python-config --ldflags no longer includes flags of the LINKFORSHARED
variable. The LINKFORSHARED variable must only be used to build
executables.

pgen (GH-12456)
Now that the parser generator is written in Python (Parser/pgen) we can make use of it to regenerate the Lib/keyword file that contains the language keywords instead of parsing the autogenerated grammar files. This also allows checking in the CI that the autogenerated files are up to date.

Pgen is the oldest piece of technology in the CPython repository, building it requires various #if[n]def PGEN hacks in other parts of the code and it also depends more and more on CPython internals. This commit removes the old pgen C code and replaces it for a new version implemented in pure Python. This is a modified and adapted version of lib2to3/pgen2 that can generate grammar files compatibles with the current parser.
This commit also eliminates all the #ifdef and code branches related to pgen, simplifying the code and making it more maintainable. The regen-grammar step now uses $(PYTHON_FOR_REGEN) that can be any version of the interpreter, so the new pgen code maintains compatibility with older versions of the interpreter (this also allows regenerating the grammar with the current CI solution that uses Python3.5). The new pgen Python module also makes use of the Grammar/Tokens file that holds the token specification, so is always kept in sync and avoids having to maintain duplicate token definitions.

`BLDSHARED` needs to have both `LDFLAGS` and `LDFLAGS_NODIST`, not just `LDFLAGS_NODIST`; `PY_CORE_LDFLAGS` provides both. For example, as it stands now with just `LDFLAGS_NODIST`, macOS universal builds are broken as the necessary `-arch` flags are no longer passed to the standard library extension module link step from `setup.py` resulting in extension modules being single architecture only.

(GH-10370)
"Include/token.h", "Lib/token.py" (containing now some data moved from
"Lib/tokenize.py") and new files "Parser/token.c" (containing the code
moved from "Parser/tokenizer.c") and "Doc/library/token-list.inc" (included
in "Doc/library/token.rst") are now generated from "Grammar/Tokens" by
"Tools/scripts/generate_token.py". The script overwrites files only if
needed and can be used on the read-only sources tree.
"Lib/symbol.py" is now generated by "Tools/scripts/generate_symbol_py.py"
instead of been executable itself.
Added new make targets "regen-token" and "regen-symbol" which are now
dependencies of "regen-all".
The documentation contains now strings for operators and punctuation tokens.
