* bpo-45950: Introduce Bootstrap Python again (#29859)Christian Heimes2021-12-032-2/+6
| | | | | | | | | 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-45952: Get the C analyzer tool working again. (gh-29882)Eric Snow2021-12-016-99/+111
| | | | | There wasn't much that needed to be done. Mostly it was just a few new files that got added. https://bugs.python.org/issue45952

* bpo-45866: pegen strips directory of "generated from" header (GH-29777)Victor Stinner2021-11-263-3/+7
| | | | | "make regen-all" now produces the same output when run from a directory other than the source tree: when building Python out of the source tree.

* bpo-45873: Get rid of bootstrap_python (#29717)Guido van Rossum2021-11-233-264/+170
| | | | | | | | | | | | | 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-45561: Run smelly.py tool from $(srcdir) (GH-29138)Neil Schemenauer2021-11-231-3/+6

* bpo-45850: Implement deep-freeze on Windows (#29648)Guido van Rossum2021-11-224-13/+416
| | | | | | Implement changes to build with deep-frozen modules on Windows. Note that we now require Python 3.10 as the "bootstrap" or "host" Python. This causes a modest startup speed (around 7%) on Windows.
* Fix out-of-tree build support for multissltest (GH-29694)Christian Heimes2021-11-221-4/+10

* bpo-45696: Deep-freeze selected modules (GH-29118)Guido van Rossum2021-11-113-17/+491
| | | | | | | 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.

* bpo-45395: Make custom frozen modules additions instead of replacements. ↵Eric Snow2021-10-282-25/+44
| | | | | | | | | (gh-28778) Currently custom modules (the array set on PyImport_FrozenModules) replace all the frozen stdlib modules. That can be problematic and is unlikely to be what the user wants. This change treats the custom frozen modules as additions instead. They take precedence over all other frozen modules except for those needed to bootstrap the import system. If the "code" field of an entry in the custom array is NULL then that frozen module is treated as disabled, which allows a custom entry to disable a frozen stdlib module. This change allows us to get rid of is_essential_frozen_module() and simplifies the logic for which frozen modules should be ignored. https://bugs.python.org/issue45395
* bpo-45629: Add a test for the "freeze" tool. (gh-29222)Eric Snow2021-10-281-0/+194
| | | | | | | The "freeze" tool has been part of the repo for a long time. However, it hasn't had any tests in the test suite to guard against regressions. We add such a test here. This is especially important as there has been a lot of change recently related to frozen modules, with more to come. Note that as part of the test we build Python out-of-tree and install it in a temp dir. https://bugs.python.org/issue45629
* bpo-43795: Add a test for Stable ABI symbol availability using ctypes (GH-26354)Petr Viktorin2021-10-221-0/+38
| | | | | | | | | This is a cross-platform check that the symbols are actually exported in the ABI, not e.g. hidden in a macro. Caveat: PyModule_Create2 & PyModule_FromDefAndSpec2 are skipped. These aren't exported on some of our buildbots. This is a bug (bpo-44133). This test now makes sure all the others don't regress.

* bpo-45494: Fix parser crash when reporting errors involving invalid ↵Pablo Galindo Salgado2021-10-191-1/+1
| | | | | | | | | | | | continuation characters (GH-28993) There are two errors that this commit fixes: * The parser was not correctly computing the offset and the string source for E_LINECONT errors due to the incorrect usage of strtok(). * The parser was not correctly unwinding the call stack when a tokenizer exception happened in rules involving optionals ('?', [...]) as we always make them return valid results by using the comma operator. We need to check first if we don't have an error before continuing.
* bpo-35081: Move interpreteridobject.h to Include/internal/ (GH-28969)Victor Stinner2021-10-151-1/+0
| | | | Move the interpreteridobject.h header file from Include/ to Include/internal/. It only provides private functions.
* po-35134: Move Include/funcobject.h to Include/cpython/ (GH-28958)Victor Stinner2021-10-141-1/+0
| | | Remove redundant "#ifndef Py_LIMITED_API" in funcobject.h.
* bpo-45340: Don't create object dictionaries unless actually needed (GH-28802)Mark Shannon2021-10-131-11/+64
| | | | | | | | | | | | | | * Never change types' cached keys. It could invalidate inline attribute objects. * Lazily create object dictionaries. * Update specialization of LOAD/STORE_ATTR. * Don't update shared keys version for deletion of value. * Update gdb support to handle instance values. * Rename SPLIT_KEYS opcodes to INSTANCE_VALUE.
* Fix EncodingWarning in test_tools. (GH-28846)Inada Naoki2021-10-101-2/+2

* bpo-45256: Remove the usage of the C stack in Python to Python calls (GH-28488)Pablo Galindo Salgado2021-10-091-29/+55
| | | | Ths commit inlines calls to Python functions in the eval loop and steals all the arguments in the call from the caller for performance.
* bpo-45402: Fix test_tools.test_sundry() (GH-28786)Victor Stinner2021-10-071-3/+4
| | | | Fix test_tools.test_sundry() when Python is built out of tree: fix how the freeze_modules.py tool locates the _freeze_module program.
* Fix typos in the Tools directory (GH-28769)Christian Clauss2021-10-0615-24/+24
