* bpo-45950: Introduce Bootstrap Python again (#29859)Christian Heimes2021-12-031-21/+42
| | | | | | | | | The build system now uses a :program:`_bootstrap_python` interpreter for freezing and deepfreezing again. To speed up build process the build tools :program:`_bootstrap_python` and :program:`_freeze_module` are no longer build with LTO. Cross building depends on a build Python interpreter, which must have same version and bytecode as target host Python.
* bpo-45582: Fix out-of-tree build issues with new getpath (GH-29902)Christian Heimes2021-12-031-8/+7

* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-9/+12
| | | | | The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code. This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.

* bpo-45886: Fix OOT build when srcdir has frozen module headers (GH-29793)Christian Heimes2021-11-261-3/+6
| | | | | | | The presence of frozen module headers in srcdir interfers with OOT build. Make considers headers in srcdir up to date, but later builds do not use VPATH to locate files. make clean now removes the headers, too. Also remove stale ``_bootstrap_python`` from .gitignore.

* bpo-45873: Get rid of bootstrap_python (#29717)Guido van Rossum2021-11-231-164/+83
| | | | | | | | | | | | | Instead we use $(PYTHON_FOR_REGEN) .../deepfreeze.py with the frozen .h file as input, as we did for Windows in bpo-45850. We also get rid of the code that generates the .h files when make regen-frozen is run (i.e., .../make_frozen.py), and the MANIFEST file.

* bpo-45573: Introduce extension module flags in Makefile (GH-29594)Christian Heimes2021-11-181-4/+14
| | | | | | | | | | | | | | | | | | ``configure`` now uses a standardized format to forward state, compiler flags, and linker flags to ``Makefile``, ``setup.py``, and ``Modules/Setup``. ``makesetup`` use the new variables by default if a module line does not contain any compiler or linker flags. ``setup.py`` has a new function ``addext()``. For a module ``egg``, configure adds: * ``MODULE_EGG`` with value yes, missing, disabled, or n/a * ``MODULE_EGG_CFLAGS`` * ``MODULE_EGG_LDFLAGS`` ``Makefile.pre.in`` may also provide ``MODULE_EGG_DEPS`` that lists dependencies such as header files and static libs.

* bpo-45800: Move pyexpat build setup into configure (GH-29547)Christian Heimes2021-11-141-3/+51
| | | | | | Settings for :mod:`pyexpat` C extension are now detected by ``configure``. The bundled ``expat`` library is built in ``Makefile``. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-45798: Move _decimal build setup into configure (GH-29541)Christian Heimes2021-11-131-2/+100

* bpo-45696: Deep-freeze selected modules (GH-29118)Guido van Rossum2021-11-111-3/+182
| | | | | | | This gains 10% or more in startup time for `python -c pass` on UNIX-ish systems. The Makefile.pre.in generating code builds on Eric's work for bpo-45020, but the .c file generator is new. Windows version TBD.
* makefile: remove unused SGI_ABI variable (GH-29325)Filipe Laíns2021-11-021-1/+0
| | | | | | | | | SGI_ABI support was removed in [1] but this variable was never removed from the makefile. Currently, it is just a bad variable that does not get replaced by the configure script. [1] https://github.com/python/cpython/pull/3294 Signed-off-by: Filipe Laíns <lains@riseup.net>

* bpo-45548: Some test modules must be built as shared libs (GH-29268)Christian Heimes2021-10-291-2/+11
| | | | | | | | | | | | | Some test cases don't work when test modules are static extensions. Add dependency on Modules/config.c to trigger a rebuild whenever a module build type is changed. ``makesetup`` puts shared extensions into ``Modules/`` directory. Create symlinks from pybuilddir so the extensions can be imported. Note: It is not possible to use the content of pybuilddir.txt as a build target. Makefile evaluates target variables in the first pass. The pybuilddir.txt file does not exist at that point.
* bpo-45548: makesetup improvements (GH-29225)Christian Heimes2021-10-261-2/+3
| | | | | | | * record which modules are build as shared extensions * put object files in same directory as source files * remove dependency on deleted _math.c Signed-off-by: Christian Heimes <christian@python.org>
* bpo-45595: Make extensions depend on header files (GH-29198)Christian Heimes2021-10-251-0/+22
| | | | | | ``setup.py`` and ``makesetup`` now track build dependencies on all Python header files and module specific header files. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-45548: Remove _math.c workarounds for pre-C99 libm (GH-29179)Christian Heimes2021-10-251-5/+1
| | | | | | | | | | | | | The :mod:`math` and :mod:`cmath` implementation now require a C99 compatible ``libm`` and no longer ship with workarounds for missing acosh, asinh, expm1, and log1p functions. The changeset also removes ``_math.c`` and moves the last remaining workaround into ``_math.h``. This simplifies static builds with ``Modules/Setup`` and resolves symbol conflicts.

* bpo-35134: Add Include/cpython/longobject.h (GH-29044)Victor Stinner2021-10-191-0/+1
| | | | | | | | | | Move Include/longobject.h non-limited API to a new Include/cpython/longobject.h header file. Move the following definitions to the internal C API: * _PyLong_DigitValue * _PyLong_FormatAdvancedWriter() * _PyLong_FormatWriter()
* bpo-35134: Split warnings.h and weakrefobject.h (GH-29042)Victor Stinner2021-10-181-0/+2
| | | | | | | | | | | | | Split header files to move the non-limited API to Include/cpython/: * Include/warnings.h => Include/cpython/warnings.h * Include/weakrefobject.h => Include/cpython/weakrefobject.h Exclude PyWeakref_GET_OBJECT() from the limited C API. It never worked since the PyWeakReference structure is opaque in the limited C API. Move _PyWarnings_Init() and _PyErr_WarnUnawaitedCoroutine() to the internal C API.
* bpo-45482: Rename namespaceobject.h to pycore_namespace.h (GH-28975)Victor Stinner2021-10-151-1/+1
| | | | | | | | | Rename Include/namespaceobject.h to Include/internal/pycore_namespace.h. The _testmultiphase extension is now built with the Py_BUILD_CORE_MODULE macro defined to access _PyNamespace_Type. object.c: remove unused "pycore_context.h" include.
* bpo-45434: Remove Include/eval.h header file (GH-28973)Victor Stinner2021-10-151-1/+0
| | | | Move Include/eval.h content into Include/ceval.h and Include/cpython/ceval.h, and remove Include/eval.h.
* bpo-35081: Move interpreteridobject.h to Include/internal/ (GH-28969)Victor Stinner2021-10-151-2/+1
| | | | Move the interpreteridobject.h header file from Include/ to Include/internal/. It only provides private functions.
* bpo-35134: Move classobject.h to Include/cpython/ (GH-28968)Victor Stinner2021-10-151-4/+4
| | | | | | | | | Move classobject.h, context.h, genobject.h and longintrepr.h header files from Include/ to Include/cpython/. Remove redundant "#ifndef Py_LIMITED_API" in context.h. Remove explicit #include "longintrepr.h" in C files. It's not needed, Python.h already includes it.
* bpo-35134: Move Include/cellobject.h to Include/cpython/ (GH-28964)Victor Stinner2021-10-151-1/+1

* bpo-35134: Add Include/cpython/floatobject.h (GH-28957)Victor Stinner2021-10-141-0/+2
| | | | | Split Include/floatobject.h into sub-files: add Include/cpython/floatobject.h and Include/internal/pycore_floatobject.h.
* bpo-45434: Remove pystrhex.h header file (GH-28923)Victor Stinner2021-10-131-1/+1
| | | | | | | | | | | | | | | Move Include/pystrhex.h to Include/internal/pycore_strhex.h. The header file only contains private functions. The following C extensions are now built with Py_BUILD_CORE_MODULE macro defined to get access to the internal C API: * _blake2 * _hashopenssl * _md5 * _sha1 * _sha3 * _ssl * binascii

* Install the __phello__ package too. (#28665)Eric Snow2021-10-011-1/+2
| | | | | I broke some buildbots by not adding __phello__ to the list of installed packages. https://bugs.python.org/issue45020
* bpo-45020: Add more test cases for frozen modules. (gh-28664)Eric Snow2021-10-011-2/+27
| | | | | I've added a number of test-only modules. Some of those cases are covered by the recently frozen stdlib modules (and some will be once we add encodings back in). However, I figured we'd play it safe by having a set of modules guaranteed to be there during tests. https://bugs.python.org/issue45020
* bpo-45020: Fix some corner cases for frozen module generation. (gh-28538)Eric Snow2021-09-241-31/+48

* bpo-45020: Fix build out of source tree (GH-28410)Victor Stinner2021-09-171-13/+13
| | | | | | * Makefile.pre.in: Add $(srcdir) when needed, remove it when it was used by mistake. * freeze_modules.py tool uses ./Programs/_freeze_module if the executable doesn't exist in the source tree.
* bpo-45020: Drop the frozen .h files from the repo. (gh-28392)Eric Snow2021-09-161-12/+14
| | | | | The main advantage is that the files will no longer show up in diffs and PRs. That means, for a PR, the number of files / lines changed will more clearly reflect the actual change. (This is essentially an un-revert of gh-28375.) https://bugs.python.org/issue45020
* bpo-45019: Clean up the frozen __hello__ module. (gh-28374)Eric Snow2021-09-151-3/+3
| | | | | Here's one more small cleanup that should have been in PR gh-28319. We eliminate stdout side-effects from importing the frozen __hello__ module, and update tests accordingly. We also move the module's source file into Lib/ from Toos/freeze/flag.py. https://bugs.python.org/issue45019
* bpo-45020: Freeze some of the modules imported during startup. (gh-28335)Eric Snow2021-09-151-12/+36
| | | | | | | Doing this provides significant performance gains for runtime startup (~15% with all the imported modules frozen). We don't yet freeze all the imported modules because there are a few hiccups in the build systems we need to sort out first. (See bpo-45186 and bpo-45188.) Note that in PR GH-28320 we added a command-line flag (-X frozen_modules=[on|off]) that allows users to opt out of (or into) using frozen modules. The default is still "off" but we will change it to "on" as soon as we can do it in a way that does not cause contributors pain. https://bugs.python.org/issue45020
* bpo-45019: Do some cleanup related to frozen modules. (gh-28319)Eric Snow2021-09-131-4/+4
| | | | | There are a few things I missed in gh-27980. This is a follow-up that will make subsequent PRs cleaner. It includes fixes to tests and tools that reference the frozen modules. https://bugs.python.org/issue45019
* bpo-45019: Add a tool to generate list of modules to include for frozen ↵Eric Snow2021-08-301-40/+53
| | | | | | | modules (gh-27980) Frozen modules must be added to several files in order to work properly. Before this change this had to be done manually. Here we add a tool to generate the relevant lines in those files instead. This helps us avoid mistakes and omissions. https://bugs.python.org/issue45019
