* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-0933-2503/+3362
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.

* bpo-32030: Add _PyImport_Fini2() (#4737)Victor Stinner2017-12-063-35/+78
| | | | | | | | | | | | | | | | | | | | | PyImport_ExtendInittab() now uses PyMem_RawRealloc() rather than PyMem_Realloc(). PyImport_ExtendInittab() can be called before Py_Initialize() whereas only the PyMem_Raw allocator is supposed to be used before Py_Initialize(). Add _PyImport_Fini2() to release the memory allocated by PyImport_ExtendInittab() at exit. PyImport_ExtendInittab() now forces the usage of the default raw allocator, to be able to release memory in _PyImport_Fini2(). Don't export these functions anymore to be C API, only to Py_BUILD_CORE: * _PyExc_Fini() * _PyImport_Fini() * _PyGC_DumpShutdownStats() * _PyGC_Fini() * _PyType_Fini() * _Py_HashRandomization_Fini()

* bpo-27240 Rewrite the email header folding algorithm. (#3488)R. David Murray2017-12-036-563/+511
| | | | | | | | | | | | | | | | | | | | | The original algorithm tried to delegate the folding to the tokens so that those tokens whose folding rules differed could specify the differences. However, this resulted in a lot of duplicated code because most of the rules were the same. The new algorithm moves all folding logic into a set of functions external to the token classes, but puts the information about which tokens can be folded in which ways on the tokens...with the exception of mime-parameters, which are a special case (which was not even implemented in the old folder). This algorithm can still probably be improved and hopefully simplified somewhat. Note that some of the test expectations are changed. I believe the changes are toward more desirable and consistent behavior: in general when (re) folding a line the canonical version of the tokens is generated, rather than preserving errors or extra whitespace.

* Refactor PyImport_ImportModuleLevelObject(). (#4680)Neil Schemenauer2017-12-031-50/+57
| | | | | | Add import_find_and_load() helper function. The addition of the importtime option has made PyImport_ImportModuleLevelObject() large and so using a helper seems worthwhile. It also makes it clearer that abs_name is the only argument needed by _find_and_load().
* bpo-32176: Set CO_NOFREE in the code object constructor (GH-4675)Nick Coghlan2017-12-034-6/+59
| | | | | | | | Previously, CO_NOFREE was set in the compiler, which meant it could end up being set incorrectly when code objects were created directly. Setting it in the constructor based on freevars and cellvars ensures it is always accurate, regardless of how the code object is defined.

* Add a minimal unit test for Python/frozen.c. (#2995)Neil Schemenauer2017-12-021-0/+30
| | | | | | If the marshal or bytecode formats get changed, frozen.c needs to be updated as well. It can be easy to miss this step and not doing so can cause test_importlib to crash in mysterious ways. Add an explict unit test to make it easier to track down the problem.
