| | | | | | | | Fix test_copyreg when numpy is installed: test.pickletester now saves/restores warnings.filters when importing numpy, to ignore filters installed by numpy. Add the save_restore_warnings_filters() function to the test.support.warnings_helper module.

* bpo-38876: Raise pickle.UnpicklingError when loading an item from memo for ↵Claudiu Popa2019-11-241-1/+3
| | | | | | | | | | | | | | | invalid input (GH-17335) The previous code was raising a `KeyError` for both the Python and C implementation. This was caused by the specified index of an invalid input which did not exist in the memo structure, where the pickle stores what objects it has seen. The malformed input would have caused either a `BINGET` or `LONG_BINGET` load from the memo, leading to a `KeyError` as the determined index was bogus. https://bugs.python.org/issue38876 https://bugs.python.org/issue38876
* Don't skip pickle check_frame_opcodes() (GH-15025)Neil Schemenauer2019-07-301-1/+0
| | | | This looks like the only place that proto 4 framing gets exercised so leave it as part of the PGO task.
* bpo-37707: Exclude expensive unit tests from PGO task (GH-15009)Neil Schemenauer2019-07-301-0/+3
| | | | | Mark some individual tests to skip when --pgo is used. The tests marked increase the PGO task time significantly and likely don't help improve optimization of the final executable.
* bpo-37502: handle default parameter for buffers argument of pickle.loads ↵Markus Mohrhard2019-07-251-0/+5

| | | | | | (GH-11859) Escape ``\r``, ``\0`` and ``\x1a`` (end-of-file on Windows) in Unicode strings.

* bpo-35900: Enable custom reduction callback registration in _pickle (GH-12499)Pierre Glaser2019-05-081-0/+68
| | | | 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 Glaser2019-05-081-1/+39
| | | | | 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.

| | | | | from sys.modules (GH-9047) Fix C implementation of pickle.loads to use importlib's locking mechanisms, and thereby avoid using partially-loaded modules.

* bpo-31993: Do not use memoryview when pickle large strings. (#5154)Serhiy Storchaka2018-01-121-30/+30
| | | | | | 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 Storchaka2018-01-111-8/+9
| | | | | | | 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 Grisel2018-01-061-13/+118
| | | | | | | | | | | | | | | | | 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-32037: Use the INT opcode for 32-bit integers in protocol 0 pickles. (#4407)Serhiy Storchaka2017-11-161-3/+3

* bpo-32032: Test both implementations of module-level pickle API. (#4401)Serhiy Storchaka2017-11-151-12/+12

* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-2/+2
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.
