| | | | | | | | | | | | (#18630) Fix a regression where the C pickle module wouldn't allow unpickling from a file-like object that doesn't expose a readinto() method.

* bpo-39426: Fix outdated default and highest protocols in docs (GH-18154)Miss Islington (bot)2020-01-241-9/+10
| | | | | | | | Some portions of the pickle documentation hadn't been updated for the pickle protocol changes in Python 3.8 (new protocol 5, default protocol 4). This PR fixes those docs. https://bugs.python.org/issue39426 (cherry picked from commit e9652e8d58392f5022759ba06b444ce970eb12db) Co-authored-by: Mark Dickinson <mdickinson@enthought.com>
* [3.8] bpo-37206: Unrepresentable default values no longer represented as ↵Serhiy Storchaka2019-09-141-16/+16
| | | | | | | | | | None. (GH-13933) (GH-16141) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all.

| | | | Enable custom reduction callback registration for functions and classes in _pickle.c, using the new Pickler's attribute ``reducer_override``.
* bpo-35900: Add a state_setter arg to save_reduce (GH-12588)Pierre Glaser2019-05-081-8/+40
| | | | | Allow reduction methods to return a 6-item tuple where the 6th item specifies a custom state-setting method that's called instead of the regular ``__setstate__`` method.

* bpo-36635: Change pyport.h for Py_BUILD_CORE_MODULE define (GH-12853)Victor Stinner2019-04-171-4/+7
| | | | | | | | | | | | | | | | | | | | Change PyAPI_FUNC(type), PyAPI_DATA(type) and PyMODINIT_FUNC macros of pyport.h when Py_BUILD_CORE_MODULE is defined. The Py_BUILD_CORE_MODULE define must be now be used to build a C extension as a dynamic library accessing Python internals: export the PyInit_xxx() function in DLL exports on Windows. Changes: * Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE now imply Py_BUILD_CORE directy in pyport.h. * ceval.c compilation now fails with an error if Py_BUILD_CORE is not defined, just to ensure that Python is build with the correct defines. * setup.py now compiles _pickle.c with Py_BUILD_CORE_MODULE define. * setup.py compiles _json.c with Py_BUILD_CORE_MODULE define, rather than Py_BUILD_CORE_BUILTIN define * PCbuild/pythoncore.vcxproj: Add Py_BUILD_CORE_BUILTIN define.
* bpo-34572: change _pickle unpickling to use import rather than retrieving ↵tjb9002019-02-181-6/+6
| | | | | from sys.modules (GH-9047) Fix C implementation of pickle.loads to use importlib's locking mechanisms, and thereby avoid using partially-loaded modules.

| | | | | | | | (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".

* bpo-35059: Cleanup usage of Python macros (GH-10648)Victor Stinner2018-11-221-7/+19
| | | | | | | | | | | | | Don't pass complex expressions but regular variables to Python macros. * _datetimemodule.c: split single large "if" into two "if" in date_new(), time_new() and datetime_new(). * _pickle.c, load_extension(): flatten complex "if" expression into more regular C code. * _ssl.c: addbool() now uses a temporary bool_obj to only evaluate the value once. * weakrefobject.c: replace "Py_INCREF(result = proxy);" with "result = proxy; Py_INCREF(result);"
* bpo-35133: Fix mistakes when concatenate string literals on different lines. ↵Serhiy Storchaka2018-11-051-2/+2
| | | | | | | | | | (GH-10284) Two kind of mistakes: 1. Missed space. After concatenating there is no space between words. 2. Missed comma. Causes unintentional concatenating in a list of strings.
* Fix incorrect error handling in _pickle.Unpickler.__init__() (GH-9630)Zackery Spytz2018-09-291-1/+1

* bpo-31993: Do not use memoryview when pickle large strings. (#5154)Serhiy Storchaka2018-01-121-2/+3
| | | | | | PyMemoryView_FromMemory() created a memoryview referring to the internal data of the string. When the string is destroyed the memoryview become referring to a freed memory.
* bpo-31993: Do not create frames for large bytes and str objects (#5114)Serhiy Storchaka2018-01-111-94/+86
| | | | | | | when serialize into memory buffer with C pickle implementations. This optimization already is performed when serialize into memory with Python pickle implementations or into a file with both implementations.
* bpo-31993: Do not allocate large temporary buffers in pickle dump. (#4353)Olivier Grisel2018-01-061-24/+114
| | | | | | | | | | | | | | | | | The picklers do no longer allocate temporary memory when dumping large bytes and str objects into a file object. Instead the data is directly streamed into the underlying file object. Previously the C implementation would buffer all content and issue a single call to file.write() at the end of the dump. With protocol 4 this behavior has changed to issue one call to file.write() per frame. The Python pickler with protocol 4 now dumps each frame content as a memoryview to an IOBytes instance that is never reused and the memoryview is no longer released after the call to write. This makes it possible for the file object to delay access to the memoryview of previous frames without forcing any additional memory copy as was already possible with the C pickler.

* bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)Eric Snow2017-09-151-39/+68
| | | | | The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls. We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.
